       "This is an assorted set I've been queuing up:

        Jeff Mahoney tracked down a tricky one where we ended up starting IO
        on the wrong mapping for special files in btrfs_evict_inode.  A few
        people reported this one on the list.

        Filipe found (and provided a test for) a difficult bug in reading
        compressed extents, and Josef fixed up some quota record keeping with
        snapshot deletion.  Chandan killed off an accounting bug during DIO
        that lead to WARN_ONs as we freed inodes"

      KVM: disable halt_poll_ns as default for s390x

      We observed some performance degradation on s390x with dynamic
      halt polling. Until we can provide a proper fix, let's enable
      halt_poll_ns as default only for supported architectures.

      Architectures are now free to set their own halt_poll_ns
      default value.

      KVM: x86: fix off-by-one in reserved bits check

      29ecd6601904 ("KVM: x86: avoid uninitialized variable warning",
      2015-09-06) introduced a not-so-subtle problem, which probably
      escaped review because it was not part of the patch context.

      Before the patch, leaf was always equal to iterator.level.  After,
      it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set,
      and when is_shadow_zero_bits_set does another "-1" the check on
      reserved bits becomes incorrect.  Using "iterator.level" in the call
      fixes this call trace:

      KVM: x86: use correct page table format to check nested page table 
reserved bits

      Intel CPUID on AMD host or vice versa is a weird case, but it can
      happen.  Handle it by checking the host CPU vendor instead of the
      guest's in reset_tdp_shadow_zero_bits_mask.  For speed, the
      check uses the fact that Intel EPT has an X (executable) bit while
      AMD NPT has NX.

      KVM: svm: do not call kvm_set_cr0 from init_vmcb

      kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the
      memslots array (SRCU protected).  Using a mini SRCU critical section
      is ugly, and adding it to kvm_arch_vcpu_create doesn't work because
      the VMX vcpu_create callback calls synchronize_srcu.

      Documentation: arm: Fix typo in the idle-states bindings examples

      The idle-states bindings mandate that the entry-method string
      in the idle-states node must be "psci" for ARM v8 64-bit systems,
      but the examples in the bindings report a wrong entry-method string.
      Owing to this typo, some dts in the kernel wrongly defined the
      entry-method property, since they likely cut and pasted the example
      definition without paying attention to the bindings definitions.

      This patch fixes the typo in the DT idle states bindings examples and
      respective dts in the kernel so that the bindings and related dts
      files are made compliant.

      gpio: mention in DT binding doc that <name>-gpio is deprecated

      The gpiolib supports parsing DT properties of the form <name>-gpio but it
      was only added for compatibility with older DT bindings that got it wrong
      and should not be used in newer bindings.

      The commit that added support for this was:

      dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names")

      but didn't update the documentation to explain this so it's been a source
      of confusion. So let's make this clear in the GPIO DT binding doc.

      PCI: Use function 0 VPD for identical functions, regular VPD for others

      932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0")
      added PCI_DEV_FLAGS_VPD_REF_F0.  Previously, we set the flag on every
      non-zero function of quirked devices.  If a function turned out to be
      different from function 0, i.e., it had a different class, vendor ID, or
      device ID, the flag remained set but we didn't make VPD accessible at all.

      Flip this around so we only set PCI_DEV_FLAGS_VPD_REF_F0 for functions 
that
      are identical to function 0, and allow regular VPD access for any other
      functions.

      PCI: Fix devfn for VPD access through function 0

      Commit 932c435caba8 ("PCI: Add dev_flags bit to access VPD through 
function
      0") passes PCI_SLOT(devfn) for the devfn parameter of pci_get_slot().
      Generally this works because we're fairly well guaranteed that a PCIe
      device is at slot address 0, but for the general case, including
      conventional PCI, it's incorrect.  We need to get the slot and then 
convert
      it back into a devfn.

      PCI/MSI: Fix MSI IRQ domains for VFs on virtual buses

      SR-IOV creates a virtual bus where bus->self is NULL.  When we add VFs and
      scan for an MSI domain, pci_set_bus_msi_domain() dereferences bus->self,
      which causes a kernel NULL pointer dereference oops.

      Scan up to the parent bus until we find a real bridge where we can get the
      MSI domain.

      ALSA: hda - Disable power_save_node for Thinkpads

      Lenovo Thinkpads with recent Realtek codecs seem suffering from click
      noises at power transition since the introduction of widget power
      saving in 4.1 kernel.  Although this might be solved by some delays in
      appropriate points, as a quick workaround, just disable the
      power_save_node feature for now.  The gain it gives is relatively
      small, and this makes the situation back to pre 4.1 time.

      This patch ended up with a bit more code changes than usual because
      the existing fixup for Thinkpads is highly chained.  Instead of adding
      yet another chain, combine a few of them into a single fixup entry, as
      a gratis cleanup.

      ALSA: hda/tegra - async probe for avoiding module loading deadlock

      The Tegra HD-audio controller driver causes deadlocks when loaded as a
      module since the driver invokes request_module() at binding with the
      codec driver.  This patch works around it by deferring the probe in a
      work like Intel HD-audio controller driver does.  Although hovering
      the codec probe stuff into udev would be a better solution, it may
      cause other regressions, so let's try this band-aid fix until the more
      proper solution gets landed.

      drm: Allow also control clients to check the drm version

      This should be harmless.
      Vmware will, due to old infrastructure reasons, be using a privileged
      control client to supply GUI layout information rather than obtaining
      it from the device. That control client will be needing access to DRM
      version information.

      drm/mgag200: Fix driver_load error handling

      mgag200_driver_load's error path just calls the drm driver's
      driver_unload op. It isn't safe to call this because it doesn't handle
      things well if driver_load fails somewhere mid way.

      Replace the call to mgag200_driver_unload with a more finegrained
      error handling path.

      drm/amdgpu: sync ce and me with SWITCH_BUFFER(2)

      we used to adopt wait_reg_mem to let CE wait before DE finish page
      updating, but from Tonga+, CE doesn't support wait_reg_mem package so
      this logic no longer works.

      so here is another approach to do same thing:
      Insert two of SWITCH_BUFFER at both front and end of vm_flush can
      guarantee that CE not go further to process IB_const before vm_flush
      done.

      Insert two of SWITCH_BUFFER also works on CI, so remove legency method
      to sync CE and ME

      v2:
      Insert double SWITCH_BUFFER at front of vm flush as well.

      drm/amdgpu: unwind properly in amdgpu_cs_parser_init()

      The amdgpu_cs_parser_init() function doesn't clean up after itself but
      instead the caller uses a free everything function amdgpu_cs_parser_fini()
      on failure.  This style of error handling is often buggy.  In this
      example, we call "drm_free_large(parser->chunks[i].kdata);" when it is
      an unintialized pointer or when "parser->chunks" is NULL.

      I fixed this bug by adding unwind code so that it frees everything that
      it allocates.

      I also mode some other very minor changes:
      1) Renamed "r" to "ret".
      2) Moved the chunk_array allocation to the start of the function.
      3) Removed some initializers which are no longer needed.

      drm/i915/bios: handle MIPI Sequence Block v3+ gracefully

      The VBT MIPI Sequence Block version 3 has forward incompatible changes:

      First, the block size in the header has been specified reserved, and the
      actual size is a separate 32-bit value within the block. The current
      find_section() function to will only look at the size in the block
      header, and, depending on what's in that now reserved size field,
      continue looking for other sections in the wrong place.

      Fix this by taking the new block size field into account. This will
      ensure that the lookups for other sections will work properly, as long
      as the new 32-bit size does not go beyond the opregion VBT mailbox size.

      Second, the contents of the block have been completely
      changed. Gracefully refuse parsing the yet unknown data version.

      cxl: Fix lockdep warning while creating afu_err_buff attribute

      Presently a lockdep warning is reported during creation of afu_err_buff
      bin_attribute for the afu. This is caused due to the variable attr.key
      not pointing to a static class key, hence the function lockdep_init_map
      reports this warning:

       BUG: key <some-address> not in .data!

      The patch fixes this issue by calling sysfs_attr_init on the
      attr_eb.attr structure before populating it with the afu_err_buff file
      details. This will populate the attr.key variable with a static class
      key so that lockdep_init_map stops complaining about the lockdep key not
      being static.

      drm/i915: workaround bad DSL readout v3

      On HSW at least (still testing other platforms, but should be harmless
      elsewhere), the DSL reg reads back as 0 when read around vblank start
      time.  This ends up confusing the atomic start/end checking code, since
      it causes the update to appear as if it crossed a frame count boundary.
      Avoid the problem by making sure we don't return scanline_offset from
      the get_crtc_scanline function.  In moving the code there, I add to add
      an additional delay since it could be called and have a legitimate 0
      result for some time (depending on the pixel clock).

      v3: use break instead of goto (Ville)

      ocfs2/dlm: fix deadlock when dispatch assert master

      The order of the following three spinlocks should be:
      dlm_domain_lock < dlm_ctxt->spinlock < dlm_lock_resource->spinlock

      But dlm_dispatch_assert_master() is called while holding
      dlm_ctxt->spinlock and dlm_lock_resource->spinlock, and then it calls
      dlm_grab() which will take dlm_domain_lock.

      Once another thread (for example, dlm_query_join_handler) has already
      taken dlm_domain_lock, and tries to take dlm_ctxt->spinlock deadlock
      happens.

      rather than the rather specific <asm-generic/unistd.h>.  Include

      x86, efi, kasan: #undef memset/memcpy/memmove per arch

      In not-instrumented code KASAN replaces instrumented memset/memcpy/memmove
      with not-instrumented analogues __memset/__memcpy/__memove.

      However, on x86 the EFI stub is not linked with the kernel.  It uses
      not-instrumented mem*() functions from arch/x86/boot/compressed/string.c

      So we don't replace them with __mem*() variants in EFI stub.

      On ARM64 the EFI stub is linked with the kernel, so we should replace
      mem*() functions with __mem*(), because the EFI stub runs before KASAN
      sets up early shadow.

      So let's move these #undef mem* into arch's asm/efi.h which is also
      included by the EFI stub.

      Also, this will fix the warning in 32-bit build reported by kbuild test
      robot:

        efi-stub-helper.c:599:2: warning: implicit declaration of function

      mm, dax: VMA with vm_ops->pfn_mkwrite wants to be write-notified

      For VM_PFNMAP and VM_MIXEDMAP we use vm_ops->pfn_mkwrite instead of
      vm_ops->page_mkwrite to notify abort write access.  This means we want
      vma->vm_page_prot to be write-protected if the VMA provides this vm_ops.

      A theoretical scenario that will cause these missed events is:

        On writable mapping with vm_ops->pfn_mkwrite, but without
        vm_ops->page_mkwrite: read fault followed by write access to the pfn.
        Writable pte will be set up on read fault and write fault will not be
        generated.

      I found it examining Dave's complaint on generic/080:

        http://lkml.kernel.org/g/20150831233803.GO3902@dastard

      Although I don't think it's the reason.

      It shouldn't be a problem for ext2/ext4 as they provide both pfn_mkwrite
      and page_mkwrite.

      userfaultfd: register uapi generic syscall (aarch64)

      Add the userfaultfd syscalls to uapi asm-generic, it was tested with
      postcopy live migration on aarch64 with both 4k and 64k pagesize
      kernels.

      userfaultfd: selftest: don't error out if pthread_mutex_t isn't identical

      On ppc big endian this check fails, the mutex doesn't necessarily need
      to be identical for all pages after pthread_mutex_lock/unlock cycles.
      The count verification (outside of the pthread_mutex_t structure)
      suffices and that is retained.

      userfaultfd: revert "userfaultfd: waitqueue: add nr wake parameter to 
__wake_up_locked_key"

      This reverts commit 51360155eccb907ff8635bd10fc7de876408c2e0 and adapts
      fs/userfaultfd.c to use the old version of that function.

      It didn't look robust to call __wake_up_common with "nr == 1" when we
      absolutely require wakeall semantics, but we've full control of what we
      insert in the two waitqueue heads of the blocked userfaults.  No
      exclusive waitqueue risks to be inserted into those two waitqueue heads
      so we can as well stick to "nr == 1" of the old code and we can rely
      purely on the fact no waitqueue inserted in one of the two waitqueue
      heads we must enforce as wakeall, has wait->flags WQ_FLAG_EXCLUSIVE set.

      PCI: Clear IORESOURCE_UNSET when clipping a bridge window

      c770cb4cb505 ("PCI: Mark invalid BARs as unassigned") sets 
IORESOURCE_UNSET
      if we fail to claim a resource.  If we tried to claim a bridge window,
      failed, clipped the window, and tried to claim the clipped window, we
      failed again because of IORESOURCE_UNSET:

        pci_bus 0000:00: root bus resource [mem 0xc0000000-0xffffffff window]
        pci 0000:00:01.0: can't claim BAR 15 [mem 0xbdf00000-0xddefffff 64bit 
pref]: no compatible bridge window
        pci 0000:00:01.0: [mem size 0x20000000 64bit pref] clipped to [mem size 
0x1df00000 64bit pref]
        pci 0000:00:01.0:   bridge window [mem size 0x1df00000 64bit pref]
        pci 0000:00:01.0: can't claim BAR 15 [mem size 0x1df00000 64bit pref]: 
no address assigned

      The 00:01.0 window started as [mem 0xbdf00000-0xddefffff 64bit pref].  
That
      starts before the host bridge window [mem 0xc0000000-0xffffffff window], 
so
      we clipped the 00:01.0 window to [mem 0xc0000000-0xddefffff 64bit pref].
      But we left it marked IORESOURCE_UNSET, so the second claim failed when it
      should have succeeded.

      This means downstream devices will also fail for lack of resources, e.g.,
      in the bugzilla below,

        radeon 0000:01:00.0: Fatal error during GPU init

      Clear IORESOURCE_UNSET when we clip a bridge window.  Also clear
      IORESOURCE_UNSET in our copy of the unclipped window so we can see exactly
      what the original window was and how it now fits inside the upstream
      window.

      Btrfs: keep dropped roots in cache until transaction commit

      When dropping a snapshot we need to account for the qgroup changes.  If 
we drop
      the snapshot in all one go then the backref code will fail to find blocks 
from
      the snapshot we dropped since it won't be able to find the root in the fs 
root
      cache.  This can lead to us failing to find refs from other roots that 
pointed
      at blocks in the now deleted root.  To handle this we need to not remove 
the fs
      roots from the cache until after we process the qgroup operations.  Do 
this by
      adding dropped roots to a list on the transaction, and letting the 
transaction
      remove the roots at the same time it drops the commit roots.  This will 
keep all
      of the backref searching code in sync properly, and fixes a problem Mark 
was
      seeing with snapshot delete and qgroups.  Thanks,

      Pull cgroup fixes from Tejun Heo:

        added write locking of a percpu_rwsem in cgroup task migration path;
        unfortunately, that involved expedited rcu syncing which turned out to
        be too slow and heavy for certain workloads.  The patchset which is
        dependent on this one didn't get committed during that devel cycle, so
        these two patches can be reverted safely.

        Oleg reworked percpu_rwsem for 4.4 so that the writer path is a lot
        lighter.  The reported issue goes away with Oleg's reworked
        percpu_rwsem and I'll reapply these patches on the for-4.4 branch so

      This means that the inode had non-zero "outstanding extents" during
      eviction. This occurs because, during direct I/O a task which successfully
      used up its reserved data space would set BTRFS_INODE_DIO_READY bit and 
does
      not clear the bit after finishing the DIO write. A future DIO write could
      actually fail and the unused reserve space won't be freed because of the
      previously set BTRFS_INODE_DIO_READY bit.

      Clearing the BTRFS_INODE_DIO_READY bit in btrfs_direct_IO() caused the
      following issue,

      Hence this commit introduces "struct btrfs_dio_data" to track the usage of
      reserved data space. The remaining unused "reserve space" can now be freed
      reliably.

      KVM: x86: trap AMD MSRs for the TSeg base and mask

      These have roughly the same purpose as the SMRR, which we do not need
      to implement in KVM.  However, Linux accesses MSR_K8_TSEG_ADDR at
      boot, which causes problems when running a Xen dom0 under KVM.
      Just return 0, meaning that processor protection of SMRAM is not
      in effect.

      NFSv4: Recovery of recalled read delegations is broken

      When a read delegation is being recalled, and we're reclaiming the
      cached opens, we need to make sure that we only reclaim read-only
      modes.
      A previous attempt to do this, relied on retrieving the delegation
      type from the nfs4_opendata structure. Unfortunately, as Kinglong
      pointed out, this field can only be set when performing reboot recovery.

      Furthermore, if we call nfs4_open_recover(), then we end up clobbering
      the state->flags for all modes that we're not recovering...

      The fix is to have the delegation recall code pass this information
      to the recovery call, and then refactor the recovery code so that
      nfs4_open_delegation_recall() does not need to call nfs4_open_recover().

kvmppc_h_logical_ci_load/store()

      Access to the kvm->buses (like with the kvm_io_bus_read() and -write()
      functions) has to be protected via the kvm->srcu lock.
      The kvmppc_h_logical_ci_load() and -store() functions are missing
      this lock so far, so let's add it there, too.
      This fixes the problem that the kernel reports "suspicious RCU usage"
      when lock debugging is enabled.

      KVM: PPC: Book3S HV: Pass the correct trap argument to kvmhv_commence_exit

      In guest_exit_cont we call kvmhv_commence_exit which expects the trap
      number as the argument. However r3 doesn't contain the trap number at
      this point and as a result we would be calling the function with a
      spurious trap number.

      Fix this by copying r12 into r3 before calling kvmhv_commence_exit as
      r12 contains the trap number.

      The bug is that kvmppc_run_vcpu does not correctly handle the case
      where a vcpu task receives a signal while its guest vcpu is executing
      in the guest as a result of being piggy-backed onto the execution of
      another vcore.  In that case we need to wait for the vcpu to finish
      executing inside the guest, and then remove this vcore from the
      preempted vcores list.  That way, we avoid leaving this vcpu's vcore
      on the preempted vcores list when the vcpu gets interrupted.

      NFS: Fix an infinite loop when layoutget fail with BAD_STATEID

      If layouget fail with BAD_STATEID, restart should not using the old 
stateid.
      But, nfs client choose the layout stateid at first, and then the open 
stateid.

      To avoid the infinite loop of using bad stateid for layoutget,
      this patch sets the layout flag'ss NFS_LAYOUT_INVALID_STID bit to
      skip choosing the bad layout stateid.

      thermal: power_allocator: exit early if there are no cooling devices

      Don't waste cycles in the power allocator governor's throttle function
      if there are no cooling devices and exit early.

      This commit doesn't change any functionality, but should provide better
      performance for the odd case of a thermal zone with trip points but
      without cooling devices.

      fs-writeback: unplug before cond_resched in writeback_sb_inodes

      Commit 505a666ee3fc ("writeback: plug writeback in wb_writeback() and
      writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes,
      which increases the merge rate when relatively contiguous small files
      are written by the filesystem.  It helps both on flash and spindles.

      For an fs_mark workload creating 4K files in parallel across 8 drives,
      this commit improves performance ~9% more by unplugging before calling
      cond_resched().  cond_resched() doesn't trigger an implicit unplug, so
      explicitly getting the IO down to the device before scheduling reduces
      latencies for anyone waiting on clean pages.

      It also cuts down on how often we use kblockd to unplug, which means
      less work bouncing from one workqueue to another.

      Many more details about how we got here:

      ASoC: fsl_ssi: Fix checking of dai format for AC97 mode

      Current code incorrectly treats dai format for AC97 as bit mask
      whereas it's actually an integer value. This causes DAI formats
      other than AC97 (e.g. DSP_B) to trigger AC97 related code,
      which is incorrect and breaks functionality. This patch fixes
      the code to correctly compare values to determine AC97 or not.

      ASoC: wm0010: fix error path

      Fix the error path so that we can free the allocated memory on the error
      path instead of releasing them individually on each error.

      ASoC: wm0010: fix memory leak

      We have requested for the firmware but we have missed releasing it both
      on success and on error path.
      While checking the code it turned out that the requested firmware is not
      even used. More over the same firmware is being loaded by
      wm0010_stage2_load().

      mm: fix type cast in __pfn_to_phys()

      The various definitions of __pfn_to_phys() have been consolidated to
      use a generic macro in include/asm-generic/memory_model.h. This hit
      mainline in the form of 012dcef3f058 "mm: move __phys_to_pfn and
      __pfn_to_phys to asm/generic/memory_model.h". When the generic macro
      was implemented the type cast to phys_addr_t was dropped which caused
      boot regressions on ARM platforms with more than 4GB of memory and
      LPAE enabled.

      It was suggested to use PFN_PHYS() defined in include/linux/pfn.h
      as provides the correct logic and avoids further duplication.

      IB/hfi: Properly set permissions for user device files

      Some of the device files are required to be user accessible for PSM while
      most should remain accessible only by root.

      Add a parameter to hfi1_cdev_init which controls if the user should have 
access
      to this device which places it in a different class with the appropriate
      devnode callback.

      In addition set the devnode call back for the existing class to be a bit 
more
      explicit for those permissions.

      Finally remove the unnecessary null check before class_destroy

         - Final split of the irq_data into chip specific and common data to
           reflect the needs of hierarchical irq domains.

         - Treewide removal of the first argument of interrupt flow handlers,
           i.e. the irq number, which is not used by the majority of handlers
           and simple to retrieve from the other argument the irq descriptor.

      kvm: svm: reset mmu on VCPU reset

      When INIT/SIPI sequence is sent to VCPU which before that
      was in use by OS, VMRUN might fail with:

       KVM: entry failed, hardware error 0xffffffff

       [...]
       EFER=0000000000000000

      with corresponding SVM error:
       KVM: FAILED VMRUN WITH VMCB:
       [...]
       cpl:            0                efer:         0000000000001000

       [...]

      What happens is that VCPU state right after offlinig:
      CR0: 0x80050033  EFER: 0xd01  CR4: 0x7e0
        -> long mode with CR3 pointing to longmode page tables

      and when VCPU gets INIT/SIPI following transition happens
      CR0: 0 -> 0x60000010 EFER: 0x0  CR4: 0x7e0
        -> paging disabled with stale CR3

      However SVM under the hood puts VCPU in Paged Real Mode*
      which effectively translates CR0 0x60000010 -> 80010010 after

         svm_vcpu_reset()
             -> init_vmcb()
                 -> kvm_set_cr0()
                     -> svm_set_cr0()

      but from  kvm_set_cr0() perspective CR0: 0 -> 0x60000010
      only caching bits are changed and
      commit d81135a57aa6
       ("KVM: x86: do not reset mmu if CR0.CD and CR0.NW are changed")'
      regressed svm_vcpu_reset() which relied on MMU being reset.

      As result VMRUN after svm_vcpu_reset() tries to run
      VCPU in Paged Real Mode with stale MMU context (longmode page tables),
      which causes some AMD CPUs** to bail out with VMEXIT_INVALID.

      Fix issue by unconditionally resetting MMU context
      at init_vmcb() time.

      sched: access local runqueue directly in single_task_running

      Commit 2ee507c47293 ("sched: Add function single_task_running to let a 
task
      check if it is the only task running on a cpu") referenced the current
      runqueue with the smp_processor_id.  When CONFIG_DEBUG_PREEMPT is enabled,
      that is only allowed if preemption is disabled or the currrent task is
      bound to the local cpu (e.g. kernel worker).

      With commit f78195129963 ("kvm: add halt_poll_ns module parameter") KVM
      calls single_task_running. If CONFIG_DEBUG_PREEMPT is enabled that
      generates a lot of kernel messages.

      To avoid adding preemption in that cases, as it would limit the 
usefulness,
      we change single_task_running to access directly the cpu local runqueue.

      s390: wire up separate socketcalls system calls

      As discussed on linux-arch all architectures should wire up the separate
      system calls that are hidden behind the socketcall multiplexer system 
call.

      It's just a couple more system calls and gives us a very small performance
      improvement.

      s390/compat: remove superfluous compat wrappers

      A couple of compat wrapper functions are simply trampolines to the real
      system call. This happened because the compat wrapper defines will only
      sign and zero extend system call parameters which are of different size
      on s390/s390x (longs and pointers).
      All other parameters will be correctly sign and zero extended by the
      normal system call wrappers.

      lib/string_helpers.c: fix infinite loop in string_get_size()

      Some string_get_size() calls (e.g.:
       string_get_size(1, 512, STRING_UNITS_10, ..., ...)
       string_get_size(15, 64, STRING_UNITS_10, ..., ...)
      ) result in an infinite loop. The problem is that if size is equal to
      divisor[units]/blk_size and is smaller than divisor[units] we'll end
      up with size == 0 when we start doing sf_cap calculations:

      For string_get_size(1, 512, STRING_UNITS_10, ..., ...) case:
         ...
         remainder = do_div(size, divisor[units]); -> size is 0, remainder is 1
         remainder *= blk_size; -> remainder is 512
         ...
         size *= blk_size; -> size is still 0
         size += remainder / divisor[units]; -> size is still 0

      The caller causing the issue is sd_read_capacity(), the problem was
      noticed on Hyper-V, such weird size was reported by host when scanning
      collides with device removal.  This is probably a separate issue worth
      fixing, this patch is intended to prevent the library routine from
      infinite looping.

      kasan: fix last shadow judgement in memory_is_poisoned_16()

      The shadow which correspond 16 bytes memory may span 2 or 3 bytes.  If
      the memory is aligned on 8, then the shadow takes only 2 bytes.  So we
      check "shadow_first_bytes" is enough, and need not to call
      "memory_is_poisoned_1(addr + 15);".  But the code "if
      (likely(!last_byte))" is wrong judgement.

      e.g.  addr=0, so last_byte = 15 & KASAN_SHADOW_MASK = 7, then the code
      will continue to call "memory_is_poisoned_1(addr + 15);"

      zcomp_create() verifies the success of zcomp_strm_{multi,single}_create()
      through comp->stream, which can potentially be pointing to memory that
      was freed if these functions returned an error.

      While at it, replace a 'ERR_PTR(-ENOMEM)' by a more generic
      'ERR_PTR(error)' as in the future zcomp_strm_{multi,siggle}_create()
      could return other error codes.  Function documentation updated
      accordingly.

      SUNRPC: Ensure that we wait for connections to complete before retrying

      Commit 718ba5b87343, moved the responsibility for unlocking the socket to
      xs_tcp_setup_socket, meaning that the socket will be unlocked before we
      know that it has finished trying to connect. The following patch is based 
on
      an initial patch by Russell King to ensure that we delay clearing the
      XPRT_CONNECTING flag until we either know that we failed to initiate
      a connection attempt, or the connection attempt itself failed.

      Failing to send a CLOSE if file is opened WRONLY and server reboots on a 
4.x mount

      A test case is as the description says:
      open(foobar, O_WRONLY);
      sleep()  --> reboot the server
      close(foobar)

      The bug is because in nfs4state.c in nfs4_reclaim_open_state() a few
      line before going to restart, there is
      clear_bit(NFS4CLNT_RECLAIM_NOGRACE, &state->flags).

      NFS4CLNT_RECLAIM_NOGRACE is a flag for the client states not open
      owner states. Value of NFS4CLNT_RECLAIM_NOGRACE is 4 which is the
      value of NFS_O_WRONLY_STATE in nfs4_state->flags. So clearing it wipes
      out state and when we go to close it, â??call_closeâ?? doesnâ??t get set 
as
      state flag is not set and CLOSE doesnâ??t go on the wire.

      of_pci_irq: Silence bogus "of_irq_parse_pci() failed ..." messages.

      It is perfectly legitimate for a PCI device to have an
      PCI_INTERRUPT_PIN value of zero.  This happens if the device doesn't
      use interrupts, or on PCIe devices, where only MSI/MSI-X are
      supported.

      Silence the annoying "of_irq_parse_pci() failed with rc=-19" error
      messages by moving the printing code into of_irq_parse_pci(), and only
      emitting the message for cases where PCI_INTERRUPT_PIN == 0 is not the
      cause for an early exit.

      devicetree: bindings: Extend the bma180 bindings with bma250 info

      The bma180 / bma250 accelerometers share a driver (at least under Linux),
      so it makes sense to also have their bindings info in a single .txt.

      This commit extends the bma180 bindings with bma250 bindings, specifically
      it specifies how the 2 seperate interrupts the bma250 has must be listed
      in devicetree. The existing bma180 driver is already fully compatible
      with the specified bindings.

      regulator: core: Correct return value check in regulator_resolve_supply

      The ret pointer passed to regulator_dev_lookup is only filled with a
      valid error code if regulator_dev_lookup returned NULL. Currently
      regulator_resolve_supply checks this ret value before it checks if a
      regulator was returned, this can result in valid regulator lookups being

      block: fix bounce_end_io

      When bio bounce is involved, one new bio and its biovecs are
      cloned from the comming bio, which can be one fast-cloned bio
      from upper layer(such as dm).

      So it is obviously wrong to assume the start index of the coming(
      original) bio's io vector is zero, which can be any value between
      0 and (bi_max_vecs - 1), especially in case of bio split.

      This patch fixes Fedora's booting oops on i386, often with the
      following kernel log together:

      block: blk-merge: fast-clone bio when splitting rw bios

      biovecs has become immutable since v3.13, so it isn't necessary
      to allocate biovecs for the new cloned bios, then we can save
      one extra biovecs allocation/copy, and the allocation is often
      not fixed-length and a bit more expensive.

      For example, if the 'max_sectors_kb' of null blk's queue is set
      as 16(32 sectors) via sysfs just for making more splits, this patch
      can increase throught about ~70% in the sequential read test over
      null_blk(direct io, bs: 1M).

      arm/arm64: KVM: Remove 'config KVM_ARM_MAX_VCPUS'

      This patch removes config option of KVM_ARM_MAX_VCPUS,
      and like other ARCHs, just choose the maximum allowed
      value from hardware, and follows the reasons:

      1) from distribution view, the option has to be
      defined as the max allowed value because it need to
      meet all kinds of virtulization applications and
      need to support most of SoCs;

      2) using a bigger value doesn't introduce extra memory
      consumption, and the help text in Kconfig isn't accurate
      because kvm_vpu structure isn't allocated until request
      of creating VCPU is sent from QEMU;

      3) the main effect is that the field of vcpus[] in 'struct kvm'
      becomes a bit bigger(sizeof(void *) per vcpu) and need more cache
      lines to hold the structure, but 'struct kvm' is one generic struct,
      and it has worked well on other ARCHs already in this way. Also,
      the world switch frequecy is often low, for example, it is ~2000
      when running kernel building load in VM from APM xgene KVM host,
      so the effect is very small, and the difference can't be observed
      in my test at all.

      Although the ThumbEE registers and traps were present in earlier
      versions of the v8 architecture, it was retrospectively removed and so
      we can do the same.

      Whilst this breaks migrating a guest started on a previous version of
      the kernel, it is much better to kill these (non existent) registers
      as soon as possible.

      When running a guest with the architected timer disabled (with QEMU and

      s390/vtime: correct scaled cputime for SMT

      The scaled cputime is supposed to be derived from the normal per-thread
      cputime by dividing it with the average thread density in the last 
interval.

      The calculation of the scaling values for the average thread density is
      incorrect. The current, incorrect calculation:

          Ci = cycle count with i active threads
          T = unscaled cputime, sT = scaled cputime
          sT = T * (C1 + C2 + ... + Cn) / (1*C1 + 2*C2 + ... + n*Cn)

      The calculation happens to yield the correct numbers for the simple cases
      with only one Ci value not zero. But for cases with multiple Ci values not
      zero it fails. E.g. on a SMT-2 system with one thread active half the time
      and two threads active for the other half of the time it fails, the 
scaling
      factor should be 3/4 but the formula gives 2/3.

      The correct formula is

          sT = T * (C1/1 + C2/2 + ... + Cn/n) / (C1 + C2 + ... + Cn)

      s390/cpum_cf: Corrected return code for unauthorized counter sets

      Previously, the cpum_cf PMU returned -EPERM if a counter is requested and
      the counter set to which the counter belongs is not authorized.  According
      to the perf_event_open() system call manual, an error code of EPERM 
indicates
      an unsupported exclude setting or CAP_SYS_ADMIN is missing.

      Use ENOENT to indicate that particular counters are not available when the
      counter set which contains the counter is not authorized.  For generic 
events,
      this might trigger a fall back, for example, to a software event.

      s390/compat: correct uc_sigmask of the compat signal frame

      The uc_sigmask in the ucontext structure is an array of words to keep
      the 64 signal bits (or 1024 if you ask glibc but the kernel sigset_t
      only has 64 bits).

      For 64 bit the sigset_t contains a single 8 byte word, but for 31 bit
      there are two 4 byte words. The compat signal handler code uses a
      simple copy of the 64 bit sigset_t to the 31 bit compat_sigset_t.
      As s390 is a big-endian architecture this is incorrect, the two words
      in the 31 bit sigset_t array need to be swapped.

      arm64: errata: add module build workaround for erratum #843419

      Cortex-A53 processors <= r0p4 are affected by erratum #843419 which can
      lead to a memory access using an incorrect address in certain sequences
      headed by an ADRP instruction.

      There is a linker fix to generate veneers for ADRP instructions, but
      this doesn't work for kernel modules which are built as unlinked ELF
      objects.

      This patch adds a new config option for the erratum which, when enabled,
      builds kernel modules with the mcmodel=large flag. This uses absolute
      addressing for all kernel symbols, thereby removing the use of ADRP as
      a PC-relative form of addressing. The ADRP relocs are removed from the
      module loader so that we fail to load any potentially affected modules.

      arm64: compat: fix vfp save/restore across signal handlers in big-endian

      When saving/restoring the VFP registers from a compat (AArch32)
      signal frame, we rely on the compat registers forming a prefix of the
      native register file and therefore make use of copy_{to,from}_user to
      transfer between the native fpsimd_state and the compat_vfp_sigframe.

      Unfortunately, this doesn't work so well in a big-endian environment.
      Our fpsimd save/restore code operates directly on 128-bit quantities
      (Q registers) whereas the compat_vfp_sigframe represents the registers
      as an array of 64-bit (D) registers. The architecture packs the compat D
      registers into the Q registers, with the least significant bytes holding
      the lower register. Consequently, we need to swap the 64-bit halves when
      converting between these two representations on a big-endian machine.

      This patch replaces the __copy_{to,from}_user invocations in our
      compat VFP signal handling code with explicit __put_user loops that
      operate on 64-bit values and swap them accordingly.

      leds:lp55xx: Correct Kconfig dependency for f/w user helper

      The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
      tries to address the firmware file handling with user helper, but it
      sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK.  Since the
      wrong option was enabled, the system got a regression -- it suffers
      from the unexpected long delays for non-present firmware files.

      This patch corrects the Kconfig dependency to the right one,
      CONFIG_FW_LOADER_USER_HELPER.  This doesn't change the fallback
      behavior but only enables UMH when needed.

      ARM: 8425/1: kgdb: Don't try to stop the machine when setting breakpoints

      In (23a4e40 arm: kgdb: Handle read-only text / modules) we moved to
      using patch_text() to set breakpoints so that we could handle the case
      when we had CONFIG_DEBUG_RODATA.  That patch used patch_text().
      Unfortunately, patch_text() assumes that we're not in atomic context
      when it runs since it needs to grab a mutex and also wait for other
      CPUs to stop (which it does with a completion).

      This would result in a stack crawl if you had
      CONFIG_DEBUG_ATOMIC_SLEEP and tried to set a breakpoint in kgdb.  The

      ARM: get rid of needless #if in signal handling code

      Remove the #if statement which caused trouble for kernels that support
      both ARMv6 and ARMv7.  Older architectures do not implement these bits,
      so it should be safe to always clear them.

      clk: check for invalid parent index of orphans in __clk_init()

      If a mux clock is initialised (by hardware or firmware) with an
      invalid parent, its ->get_parent() can return an out of range
      index.  For example, the generic mux clock attempts to return
      -EINVAL, which due to the u8 return type ends up a rather large
      number.  Using this index with the parent_names[] array results
      in an invalid pointer and (usually) a crash in the following
      strcmp().

      This patch adds a check for the parent index being in range,
      ignoring clocks reporting invalid values.

      ASoC: fix broken pxa SoC support

      The previous fix of pxa library support, which was introduced to fix the
      library dependency, broke the previous SoC behavior, where a machine
      code binding pxa2xx-ac97 with a coded relied on :
       - sound/soc/pxa/pxa2xx-ac97.c
       - sound/soc/codecs/XXX.c

      For example, the mioa701_wm9713.c machine code is currently broken. The
      "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
      compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
      in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

      Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
      pxa2xx-ac97 compilation.

      arm/arm64: KVM: vgic: Check for !irqchip_in_kernel() when mapping 
resources

      Until b26e5fdac43c ("arm/arm64: KVM: introduce per-VM ops"),
      kvm_vgic_map_resources() used to include a check on irqchip_in_kernel(),
      and vgic_v2_map_resources() still has it.

      But now vm_ops are not initialized until we call kvm_vgic_create().
      Therefore kvm_vgic_map_resources() can being called without a VGIC,
      and we die because vm_ops.map_resources is NULL.

      Fixing this restores QEMU's kernel-irqchip=off option to a working state,
      allowing to use GIC emulation in userspace.

      arm64: Remove ununsed set_irq_flags

      Now that all users of set_irq_flags and custom flags are converted to
      genirq functions, the ARM specific set_irq_flags can be removed.

      sh: Kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      x86/platform: Fix Geode LX timekeeping in the generic x86 build

      In 2007, commit 07190a08eef36 ("Mark TSC on GeodeLX reliable")
      bypassed verification of the TSC on Geode LX. However, this code
      (now in the check_system_tsc_reliable() function in
      arch/x86/kernel/tsc.c) was only present if CONFIG_MGEODE_LX was
      set.

      OpenWRT has recently started building its generic Geode target
      for Geode GX, not LX, to include support for additional
      platforms. This broke the timekeeping on LX-based devices,
      because the TSC wasn't marked as reliable:
      https://dev.openwrt.org/ticket/20531

      By adding a runtime check on is_geode_lx(), we can also include
      the fix if CONFIG_MGEODEGX1 or CONFIG_X86_GENERIC are set, thus
      fixing the problem.

      arm: KVM: Fix incorrect device to IPA mapping

      A critical bug has been found in device memory stage1 translation for
      VMs with more then 4GB of address space. Once vm_pgoff size is smaller
      then pa (which is true for LPAE case, u32 and u64 respectively) some
      more significant bits of pa may be lost as a shift operation is performed
      on u32 and later cast onto u64.

      Example: vm_pgoff(u32)=0x00210030, PAGE_SHIFT=12
              expected pa(u64):   0x0000002010030000
              produced pa(u64):   0x0000000010030000

      The fix is to change the order of operations (casting first onto 
phys_addr_t
      and then shifting).

      genirq: Remove irq argument from irq flow handlers

      Most interrupt flow handlers do not use the irq argument. Those few
      which use it can retrieve the irq number from the irq descriptor.

      Remove the argument.

      Search and replace was done with coccinelle and some extra helper
      scripts around it. Thanks to Julia for her help!

      KVM: vmx: fix VPID is 0000H in non-root operation

      Reference SDM 28.1:

      The current VPID is 0000H in the following situations:
      - Outside VMX operation. (This includes operation in system-management
        mode under the default treatment of SMIs and SMM with VMX operation;
        see Section 34.14.)
      - In VMX root operation.
      - In VMX non-root operation when the â??enable VPIDâ?? VM-execution 
control
        is 0.

      The VPID should never be 0000H in non-root operation when "enable VPID"
      VM-execution control is 1. However, commit 34a1cd60 ("kvm: x86: vmx:
      move some vmx setting from vmx_init() to hardware_setup()") remove the
      codes which reserve 0000H for VMX root operation.

      This patch fix it by again reserving 0000H for VMX root operation.

      powerpc/mm: Recompute hash value after a failed update

      If we had secondary hash flag set, we ended up modifying hash value in
      the updatepp code path. Hence with a failed updatepp we will be using
      a wrong hash value for the following hash insert. Fix this by
      recomputing hash before insert.

      Without this patch we can end up with using wrong slot number in linux
      pte. That can result in us missing an hash pte update or invalidate
      which can cause memory corruption or even machine check.

      KVM: add halt_attempted_poll to VCPU stats

      This new statistic can help diagnosing VCPUs that, for any reason,
      trigger bad behavior of halt_poll_ns autotuning.

      For example, say halt_poll_ns = 480000, and wakeups are spaced exactly
      like 479us, 481us, 479us, 481us. Then KVM always fails polling and wastes
      10+20+40+80+160+320+480 = 1110 microseconds out of every
      479+481+479+481+479+481+479 = 3359 microseconds. The VCPU then
      is consuming about 30% more CPU than it would use without
      polling.  This would show as an abnormally high number of
      attempted polling compared to the successful polls.

      ARM: fix Thumb2 signal handling when ARMv6 is enabled

      When a kernel is built covering ARMv6 to ARMv7, we omit to clear the
      IT state when entering a signal handler.  This can cause the first
      few instructions to be conditionally executed depending on the parent
      context.

      In any case, the original test for >= ARMv7 is broken - ARMv6 can have
      Thumb-2 support as well, and an ARMv6T2 specific build would omit this
      code too.

      Relax the test back to ARMv6 or greater.  This results in us always
      clearing the IT state bits in the PSR, even on CPUs where these bits
      are reserved.  However, they're reserved for the IT state, so this
      should cause no harm.

      dax: fix O_DIRECT I/O to the last block of a blockdev

      commit bbab37ddc20b (block: Add support for DAX reads/writes to
      block devices) caused a regression in mkfs.xfs.  That utility
      sets the block size of the device to the logical block size
      using the BLKBSZSET ioctl, and then issues a single sector read
      from the last sector of the device.  This results in the dax_io
      code trying to do a page-sized read from 512 bytes from the end
      of the device.  The result is -ERANGE being returned to userspace.

      The fix is to align the block to the page size before calling
      get_block.

      PCI: Revert "PCI: Call pci_read_bridge_bases() from core instead of arch 
code"

      Revert dff22d2054b5 ("PCI: Call pci_read_bridge_bases() from core instead
      of arch code").

      Reading PCI bridge windows is not arch-specific in itself, but there is 
PCI
      core code that doesn't work correctly if we read them too early.  For
      example, Hannes found this case on an ARM Freescale i.mx6 board:

        pci_bus 0000:00: root bus resource [mem 0x01000000-0x01efffff]
        pci 0000:00:00.0: PCI bridge to [bus 01-ff]
        pci 0000:00:00.0: BAR 8: no space for [mem size 0x01000000] (mem window)
        pci 0000:01:00.0: BAR 2: failed to assign [mem size 0x00200000]
        pci 0000:01:00.0: BAR 1: failed to assign [mem size 0x00004000]
        pci 0000:01:00.0: BAR 0: failed to assign [mem size 0x00000100]

      The 00:00.0 mem window needs to be at least 3MB: the 01:00.0 device needs
      0x204100 of space, and mem windows are megabyte-aligned.

      Bus sizing can increase a bridge window size, but never *decrease* it (see
      d65245c3297a ("PCI: don't shrink bridge resources")).  Prior to
      dff22d2054b5, ARM didn't read bridge windows at all, so the "original 
size"
      was zero, and we assigned a 3MB window.

      After dff22d2054b5, we read the bridge windows before sizing the bus.  The
      firmware programmed a 16MB window (size 0x01000000) in 00:00.0, and since
      we never decrease the size, we kept 16MB even though we only needed 3MB.
      But 16MB doesn't fit in the host bridge aperture, so we failed to assign
      space for the window and the downstream devices.

      I think this is a defect in the PCI core: we shouldn't rely on the 
firmware
      to assign sensible windows.

      Ray reported a similar problem, also on ARM, with Broadcom iProc.

      Issues like this are too hard to fix right now, so revert dff22d2054b5.

      irqchip/renesas-irqc: Propagate wake-up settings to parent

      The renesas-irqc interrupt controller is cascaded to the GIC, but its
      driver doesn't propagate wake-up settings to the parent interrupt
      controller.

      Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and
      MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and
      wake-up through gpio-keys now fails on r8a73a4/ape6evm.

      Fix this by propagating wake-up settings to the parent interrupt
      controller. There's no need to handle irq_set_irq_wake() failures, as
      the renesas-irqc interrupt controller is always cascaded to a GIC, and
      the GIC driver always sets SKIP_SET_WAKE since the aforementioned
      commit.

      irqchip/renesas-intc-irqpin: Propagate wake-up settings to parent

      The renesas-intc-irqpin interrupt controller is cascaded to the GIC, but
      its driver doesn't propagate wake-up settings to the parent interrupt
      controller.

      Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and
      MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and
      wake-up through gpio-keys now fails on r8a7740/armadillo and
      sh73a0/kzm9g.

      Fix this by propagating wake-up settings to the parent interrupt
      controller. There's no need to handle irq_set_irq_wake() failures, as
      the renesas-intc-irqpin interrupt controller is always cascaded to a
      GIC, and the GIC driver always sets SKIP_SET_WAKE since the
      aforementioned commit.

      After GICv2m was enabled for 32-bit ARM kernel, a warning popped up:

      irqchip/gic-v3-its: Add missing cache flushes

      When the ITS is configured for non-cacheable transactions, make sure
      that the allocated, zeroed memory is flushed to the Point of
      Coherency, allowing the ITS to observe the zeros instead of random
      garbage (or even get its own data overwritten by zeros being evicted
      from the cache...).

      irqchip/GIC: Add workaround for aliased GIC400

      The GICv2 architecture mandates that the two 4kB GIC regions are
      contiguous, and on two separate physical pages (so that access to
      the second page can be trapped by a hypervisor). This doesn't work
      very well when PAGE_SIZE is 64kB.

      A relatively common hack^Wway to work around this is to alias each
      4kB region over its own 64kB page. Of course in this case, the base
      address you want to use is not really the begining of the region,
      but base + 60kB (so that you get a contiguous 8kB region over two
      distinct pages).

      Normally, this would be described in DT with a new property, but
      some HW is already out there, and the firmware makes sure that
      it will override whatever you put in the GIC node. Duh. And of course,
      said firmware source code is not available, despite being based
      on u-boot.

      The workaround is to detect the case where the CPU interface size
      is set to 128kB, and verify the aliasing by checking that the ID
      register for GIC400 (which is the only GIC wired this way so far)
      is the same at base and base + 0xF000. In this case, we update
      the GIC base address and let it roll.

      And if you feel slightly sick by looking at this, rest assured that
      I do too...

      platform-msi: Do not cache msi_desc in handler_data

      The current implementation of platform MSI caches the msi_desc
      pointer in irq_data::handler_data. This is a bit silly, as
      we also have irq_data::msi_desc, which is perfectly valid.

      Remove the useless assignment and simplify the whole flow.

      kvm: fix zero length mmio searching

      Currently, if we had a zero length mmio eventfd assigned on
      KVM_MMIO_BUS. It will never be found by kvm_io_bus_cmp() since it
      always compares the kvm_io_range() with the length that guest
      wrote. This will cause e.g for vhost, kick will be trapped by qemu
      userspace instead of vhost. Fixing this by using zero length if an
      iodevice is zero length.

      kvm: fix double free for fast mmio eventfd

      We register wildcard mmio eventfd on two buses, once for KVM_MMIO_BUS
      and once on KVM_FAST_MMIO_BUS but with a single iodev
      instance. This will lead to an issue: kvm_io_bus_destroy() knows
      nothing about the devices on two buses pointing to a single dev. Which
      will lead to double free[1] during exit. Fix this by allocating two
      instances of iodevs then registering one on KVM_MMIO_BUS and another
      on KVM_FAST_MMIO_BUS.

      This patch ensures that the register is initialised so that all traps

      perf evlist: Remove redundant validation from propagate_maps()

      The validation checks that the values that were just assigned, got
      assigned i.e. the error can't ever happen.  Subsequent patches will call
      this code in places where errors are not being returned.  Changing those
      code paths to return this non-existent error is counter-productive, so
      just remove it.

      That in turn results in perf_evlist__set_maps not needing to return an
      error, but callers aren't checking it either, so remove that too.

      cxl: Fix build failure due to -Wunused-variable behaviour change

      A recent change in gcc caused this build failure:

      
/var/lib/jenkins/workspace/gcc_kernel_build/linux/drivers/misc/cxl/cxl.h:72:27:
      error: â??CXL_PSL_DLCNTLâ?? defined but not used 
[-Werror=unused-const-variable]
       static const cxl_p1_reg_t CXL_PSL_DLCNTL  = {0x0060};

      Because of this gcc commit:

      Commit 1bca8cbd0c68366f07277f98ce6963e10c2aa617 by mark
      PR28901 -Wunused-variable ignores unused const initialised variables in C
      12 years ago it was decided that -Wunused-variable shouldn't warn about
      static const variables because some code used const static char rcsid[]
      strings which were never used but wanted in the code anyway. But as the
      bug points out this hides some real bugs. These days the usage of
      rcsids is not very popular anymore. So this patch changes the default
      to warn about unused static const variables in C with
      -Wunused-variable. And it adds a new option -Wno-unused-const-variable
      to turn this warning off. For C++ this new warning is off by default,
      since const variables can be used as #defines in C++. New testcases for
      the new defaults in C and C++ are included testing the new warning and
      suppressing it with an unused attribute or using
      -Wno-unused-const-variable. gcc/ChangeLog

      The cxl driver uses static consts in place of #defines in some cases
      for type safety, so this change causes the driver to fail to build on
      new copilers as these constants are not all used in every file that
      imports the header. Suppress the warning for this driver to return to
      the old behaviour of -Wunused-variable.

      cxl: Fix unbalanced pci_dev_get in cxl_probe

      Currently the first thing we do in cxl_probe is to grab a reference
      on the pci device. Later on, we call device_register on our adapter.
      In our remove path, we call device_unregister, but we never call
      pci_dev_put. We therefore leak the device every time we do a
      reflash.

      device_register/unregister is sufficient to hold the reference.
      Therefore, drop the call to pci_dev_get.

      Here's why this is safe.
      The proposed cxl_probe(pdev) calls cxl_adapter_init:
          a) init calls cxl_adapter_alloc, which creates a struct cxl,
             conventionally called adapter. This struct contains a
             device entry, adapter->dev.

          b) init calls cxl_configure_adapter, where we set
             adapter->dev.parent = &dev->dev (here dev is the pci dev)

      So at this point, the cxl adapter's device's parent is the PCI
      device that I want to be refcounted properly.

          c) init calls cxl_register_adapter
             *) cxl_register_adapter calls device_register(&adapter->dev)

      So now we're in device_register, where dev is the adapter device, and
      we want to know if the PCI device is safe after we return.

      device_register(&adapter->dev) calls device_initialize() and then
      device_add().

      device_add() does a get_device(). device_add() also explicitly grabs
      the device's parent, and calls get_device() on it:

               parent = get_device(dev->parent);

      So therefore, device_register() takes a lock on the parent PCI dev,
      which is what pci_dev_get() was guarding. pci_dev_get() can therefore
      be safely removed.

      drm/ttm: Fix memory space allocation v2

      In the event that TTM doesn't find a compatible memory type for the
      driver's first placement choice (placement without eviction), TTM
      returns -EINVAL without trying the driver's second choice.
      This causes problems on vmwgfx when VRAM is disabled before first modeset
      and during VT switches when fbdev is not enabled.

      Fix this by also trying the driver's second choice before returning
      -EINVAL.

      v2: Also check that man->use_type is true for the driver's second choice.
      Fixes a bug where disallowed memory types could be used.

      btrfs: skip waiting on ordered range for special files

      In btrfs_evict_inode, we properly truncate the page cache for evicted
      inodes but then we call btrfs_wait_ordered_range for every inode as well.
      It's the right thing to do for regular files but results in incorrect
      behavior for device inodes for block devices.

      filemap_fdatawrite_range gets called with inode->i_mapping which gets
      resolved to the block device inode before getting passed to
      wbc_attach_fdatawrite_inode and ultimately to inode_to_bdi.  What happens
      next depends on whether there's an open file handle associated with the
      inode.  If there is, we write to the block device, which is unexpected
      behavior.  If there isn't, we through normally and inode->i_data is used.
      We can also end up racing against open/close which can result in crashes
      when i_mapping points to a block device inode that has been closed.

      Since there can't be any page cache associated with special file inodes,
      it's safe to skip the btrfs_wait_ordered_range call entirely and avoid
      the problem.

      Btrfs: fix read corruption of compressed and shared extents

      If a file has a range pointing to a compressed extent, followed by
      another range that points to the same compressed extent and a read
      operation attempts to read both ranges (either completely or part of
      them), the pages that correspond to the second range are incorrectly
      filled with zeroes.

      Consider the following example:

        File layout
        [0 - 8K]                      [8K - 24K]
            |                             |
            |                             |
         points to extent X,         points to extent X,
         offset 4K, length of 8K     offset 0, length 16K

        [extent X, compressed length = 4K uncompressed length = 16K]

      If a readpages() call spans the 2 ranges, a single bio to read the extent
      is submitted - extent_io.c:submit_extent_page() would only create a new
      bio to cover the second range pointing to the extent if the extent it
      points to had a different logical address than the extent associated with
      the first range. This has a consequence of the compressed read end io
      handler (compression.c:end_compressed_bio_read()) finish once the extent
      is decompressed into the pages covering the first range, leaving the
      remaining pages (belonging to the second range) filled with zeroes (done
      by compression.c:btrfs_clear_biovec_end()).

      So fix this by submitting the current bio whenever we find a range
      pointing to a compressed extent that was preceded by a range with a
      different extent map. This is the simplest solution for this corner
      case. Making the end io callback populate both ranges (or more, if we
      have multiple pointing to the same extent) is a much more complex
      solution since each bio is tightly coupled with a single extent map and
      the extent maps associated to the ranges pointing to the shared extent
      can have different offsets and lengths.

      The following test case for fstests triggers the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

            rm -f $tmp.*

      Then on the resulting empty interface, press right key:

      x86/apic: Serialize LVTT and TSC_DEADLINE writes

      The APIC LVTT register is MMIO mapped but the TSC_DEADLINE register is an
      MSR. The write to the TSC_DEADLINE MSR is not serializing, so it's not
      guaranteed that the write to LVTT has reached the APIC before the
      TSC_DEADLINE MSR is written. In such a case the write to the MSR is
      ignored and as a consequence the local timer interrupt never fires.

      The SDM decribes this issue for xAPIC and x2APIC modes. The
      serialization methods recommended by the SDM differ.

      xAPIC:
       "1. Memory-mapped write to LVT Timer Register, setting bits 18:17 to 10b.
        2. WRMSR to the IA32_TSC_DEADLINE MSR a value much larger than current 
time-stamp counter.
        3. If RDMSR of the IA32_TSC_DEADLINE MSR returns zero, go to step 2.
        4. WRMSR to the IA32_TSC_DEADLINE MSR the desired deadline."

      x2APIC:
       "To allow for efficient access to the APIC registers in x2APIC mode,
        the serializing semantics of WRMSR are relaxed when writing to the
        APIC registers. Thus, system software should not use 'WRMSR to APIC
        registers in x2APIC mode' as a serializing instruction. Read and write
        accesses to the APIC registers will occur in program order. A WRMSR to
        an APIC register may complete before all preceding stores are globally
        visible; software can prevent this by inserting a serializing
        instruction, an SFENCE, or an MFENCE before the WRMSR."

      The xAPIC method is to just wait for the memory mapped write to hit
      the LVTT by checking whether the MSR write has reached the hardware.
      There is no reason why a proper MFENCE after the memory mapped write would
      not do the same. Andi Kleen confirmed that MFENCE is sufficient for the
      xAPIC case as well.

      Issue MFENCE before writing to the TSC_DEADLINE MSR. This can be done
      unconditionally as all CPUs which have TSC_DEADLINE also have MFENCE
      support.

      x86/ioapic: Force affinity setting in setup_ioapic_dest()

      The recent ioapic cleanups changed the affinity setting in
      setup_ioapic_dest() from a direct write to the hardware to the delayed
      affinity setup via irq_set_affinity().

      That results in a warning from chained_irq_exit():
      WARNING: CPU: 0 PID: 5 at kernel/irq/migration.c:32 irq_move_masked_irq
      [<ffffffff810a0a88>] irq_move_masked_irq+0xb8/0xc0
      [<ffffffff8103c161>] ioapic_ack_level+0x111/0x130
      [<ffffffff812bbfe8>] intel_gpio_irq_handler+0x148/0x1c0

      The reason is that irq_set_affinity() does not write directly to the
      hardware. It marks the affinity setting as pending and executes it
      from the next interrupt. The chained handler infrastructure does not
      take the irq descriptor lock for performance reasons because such a
      chained interrupt is not visible to any interfaces. So the delayed
      affinity setting triggers the warning in irq_move_masked_irq().

      Restore the old behaviour by calling the set_affinity function of the
      ioapic chip in setup_ioapic_dest(). This is safe as none of the
      interrupts can be on the fly at this point.

      dm crypt: constrain crypt device's max_segment_size to PAGE_SIZE

      Setting the dm-crypt device's max_segment_size to PAGE_SIZE is an
      unfortunate constraint that is required to avoid the potential for
      exceeding dm-crypt's underlying device's max_segments limits -- due to
      crypt_alloc_buffer() possibly allocating pages for the encryption bio
      that are not as physically contiguous as the original bio.

      It is interesting to note that this problem was already fixed back in
      2007 via commit 91e106259 ("dm crypt: use bio_add_page").  But Linux 4.0
      commit cf2f1abfb ("dm crypt: don't allocate pages for a partial
      request") regressed dm-crypt back to _not_ using bio_add_page().  But
      given dm-crypt's cpu parallelization changes all depend on commit
      cf2f1abfb's abandoning of the more complex io fragments processing that
      dm-crypt previously had we cannot easily go back to using
      bio_add_page().

      So all said the cleanest way to resolve this issue is to fix dm-crypt to
      properly constrain the original bios entering dm-crypt so the encryption
      bios that dm-crypt generates from the original bios are always
      compatible with the underlying device's max_segments queue limits.

      It should be noted that technically Linux 4.3 does _not_ need this fix
      because of the block core's new late bio-splitting capability.  But, it
      is reasoned, there is little to be gained by having the block core split
      the encrypted bio that is composed of PAGE_SIZE segments.  That said, in
      the future we may revert this change.

      KVM: arm64: add workaround for Cortex-A57 erratum #852523

      When restoring the system register state for an AArch32 guest at EL2,
      writes to DACR32_EL2 may not be correctly synchronised by Cortex-A57,
      which can lead to the guest effectively running with junk in the DACR
      and running into unexpected domain faults.

      This patch works around the issue by re-ordering our restoration of the
      AArch32 register aliases so that they happen before the AArch64 system
      registers. Ensuring that the registers are restored in this order
      guarantees that they will be correctly synchronised by the core.

      The power allocator governor currently requires that a sustainable power
      is passed as part of the thermal zone's thermal zone parameters.  If

      While this parameter is strongly recommended for optimal performance, it
      doesn't need to be mandatory.  Relax the requirement and allow the
      governor to bind to thermal zones that don't provide it by estimating it
      from the cooling devices' power model.

      Depending on CONFIG_ARM64_HW_AFDBM, we use either bit 57 or 51 of the
      pte to represent PTE_WRITE. Given that bit 51 is reserved prior to
      ARMv8.1, we can just use that bit regardless of the config option. That
      also matches what happens if a kernel configured with ARM64_HW_AFDBM=y
      is run on a CPU without the DBM functionality.

      arm64: Fix pte_modify() to preserve the hardware dirty information

      The pte_modify() function with hardware AF/DBM enabled must transfer the
      hardware dirty information to the software PTE_DIRTY bit. However, it
      was setting this bit in newprot and the mask does not cover such bit.
      This patch sets PTE_DIRTY on the original pte which will be preserved in
      the returned value.

      arm64: Fix the pte_hw_dirty() check when AF/DBM is enabled

      Commit 2f4b829c625e ("arm64: Add support for hardware updates of the
      access and dirty pte bits") introduced support for handling hardware
      updates of the access flag and dirty status. The PTE is automatically
      dirtied in hardware (if supported) by clearing the PTE_RDONLY bit when
      the PTE_DBM/PTE_WRITE bit is set. The pte_hw_dirty() macro was added to
      detect a hardware dirtied pte. The pte_dirty() macro checks for both
      software PTE_DIRTY and pte_hw_dirty().

      Functions like pte_modify() clear the PTE_RDONLY bit since it is meant
      to be set in set_pte_at() when written to memory. In such cases,
      pte_hw_dirty() would return true even though such pte is clean. This
      patch changes pte_hw_dirty() to test the PTE_DBM/PTE_WRITE bit together
      with PTE_RDONLY.

access and dirty pte bits")

      arm64: dma-mapping: check whether cma area is initialized or not

      If CMA is turned on and CMA size is set to zero, kernel should
      behave as if CMA was not enabled at compile time.
      Every dma allocation should check existence of cma area
      before requesting memory.

      Arm has done this by commit e464ef16c4f0 ("arm: dma-mapping: add
      checking cma area initialized"), also do this for arm64.

      x86/ldt: Fix small LDT allocation for Xen

      While the following commit:

        37868fe113 ("x86/ldt: Make modify_ldt synchronous")

      added a nice comment explaining that Xen needs page-aligned
      whole page chunks for guest descriptor tables, it then
      nevertheless used kzalloc() on the small size path.

      As I'm unaware of guarantees for kmalloc(PAGE_SIZE, ) to return
      page-aligned memory blocks, I believe this needs to be switched
      back to __get_free_page() (or better get_zeroed_page()).

      drm/vmwgfx: Map the fifo as cached

      On the guest kernel side, previously the FIFO has been mapped write-
      combined. This has worked since VMs up to now has not honored the mapping
      type and mapped the FIFO cached anyway. Since the FIFO is accessed cached
      by the CPU on the virtual device side, this leads to inconsistent
      mappings once the guest starts to honor the mapping types.

      So ask for cached mappings when we map the FIFO. We do this by
      using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup.
      On the TTM side, MOBs, GMRs and VRAM buffers are already requesting
      cached mappings for kernel- and user-space.

      drm/vmwgfx: Fix up user_dmabuf refcounting

      If user space calls unreference on a user_dmabuf it will typically
      kill the struct ttm_base_object member which is responsible for the
      user-space visibility. However the dmabuf part may still be alive and
      refcounted. In some situations, like for shared guest-backed surface
      referencing/opening, the driver may try to reference the
      struct ttm_base_object member again, causing an immediate kernel warning
      and a later kernel NULL pointer dereference.

      Fix this by always maintaining a reference on the struct
      ttm_base_object member, in situations where it might subsequently be
      referenced.

      gpio: sx150x: Remove unnecessary MODULE_ALIAS()

      The driver has a I2C device id table that is used to create the module
      aliases and also "sx150x" isn't a supported I2C id, so it's never used.

      The con_id parameter has to match the GPIO description and is 
automatically

      gpio: Propagate errors from chip->get()

      It's possible to have gpio chips hanging off unreliable remote buses
      where the get() operation will fail to acquire a readout of the current
      gpio state. Propagate these errors to the consumer so that they can
      act on, retry or ignore these failing reads, instead of treating them as
      the line being held high.

      drivers: sh: Disable PM runtime for multi-platform ARM with genpd

      If the default PM Domain using PM_CLK is used for PM runtime, the real
      Clock Domain cannot be registered from DT later.

      Hence do not enable it when running a multi-platform kernel with genpd
      support on R-Car or RZ.  The CPG/MSTP Clock Domain driver will take care
      of PM runtime management of the module clocks.

      Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile,
      R-Car, RZ) use DT-based PM Domains to take care of PM runtime management
      of the module clocks, simplify the platform logic by replacing the
      explicit SoC checks by a single check for the presence of MSTP clocks in
      DT.

      Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided
      by checking for the presence of a "#power-domain-cells" property in DT.

      The default PM Domain is still needed for:
        - backwards-compatibility with old DTs that lack PM Domain properties,
        - the CONFIG_PM=n case,
        - legacy (non-DT) ARM/shmobile platforms without genpd support
          (r8a7778, r8a7779),
        - legacy SuperH.

      perf header: Fixup reading of HEADER_NRCPUS feature

      The original patch introducing this header wrote the number of CPUs 
available
      and online in one order and then swapped those values when reading, fix 
it.

      Before:

        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 4
        # echo 0 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 3
        # echo 0 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 2

      After the fix, bringing back the CPUs online:

        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 2
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'

      time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of 
abs64()

      The internal clocksteering done for fine-grained error
      correction uses a logarithmic approximation, so any time
      adjtimex() adjusts the clock steering, timekeeping_freqadjust()
      quickly approximates the correct clock frequency over a series
      of ticks.

      Unfortunately, the logic in timekeeping_freqadjust(), introduced
      in commit:

        dc491596f639 ("timekeeping: Rework frequency adjustments to work better 
w/ nohz")

      used the abs() function with a s64 error value to calculate the
      size of the approximated adjustment to be made.

      Per include/linux/kernel.h:

        "abs() should not be used for 64-bit types (s64, u64, long long) - use 
abs64()".

      Thus on 32-bit platforms, this resulted in the clocksteering to
      take a quite dampended random walk trying to converge on the
      proper frequency, which caused the adjustments to be made much
      slower then intended (most easily observed when large
      adjustments are made).

      This patch fixes the issue by using abs64() instead.

      924e101a7ab6 ("x86/debug: Dump family, model, stepping of the

      blk: rq_data_dir() should not return a boolean

      rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
      a boolean value.

      Now, admittedly the "!= 0" doesn't really change the value (0 stays as
      zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
      causes gcc to warn about the construct

          switch (rq_data_dir(req)) {
              case READ:
                  ...
              case WRITE:
                  ...

      that we have in a few drivers.

      Now, the gcc warning is silly and stupid (it seems to warn not about the
      switch value having a different type from the case statements, but about
      _any_ boolean switch value), but in this case the code itself is silly
      and stupid too, so let's just change it, and get rid of warnings like
      this:

        drivers/block/hd.c: In function â??hd_requestâ??:
        drivers/block/hd.c:630:11: warning: switch condition has boolean value 
[-Wswitch-bool]
           switch (rq_data_dir(req)) {

      The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
      commit 5953316dbf90 ("block: make rq->cmd_flags be 64-bit") and is
      presumably because the old code (that just did a logical 'and' with 1)
      would then end up making the type of rq_data_dir() be u64 too.

      But if we want to retain the old regular integer type, let's just cast
      the result to 'int' rather than use that rather odd '!= 0'.

      writeback: plug writeback in wb_writeback() and writeback_inodes_wb()

      We had to revert the pluggin in writeback_sb_inodes() because the
      wb->list_lock is held, but we could easily plug at a higher level before
      taking that lock, and unplug after releasing it.  This does that.

      Chris will run performance numbers, just to verify that this approach is
      comparable to the alternative (we could just drop and re-take the lock
      around the blk_finish_plug() rather than these two commits.

      I'd have preferred waiting for actual performance numbers before picking
      one approach over the other, but I don't want to release rc1 with the
      known "sleeping function called from invalid context" issue, so I'll
      pick this cleanup version for now.  But if the numbers show that we
      really want to plug just at the writeback_sb_inodes() level, and we
      should just play ugly games with the spinlock, we'll switch to that.

      thermal: fix intel PCH thermal driver mismerge

      I didn't notice this when merging the thermal code from Zhang, but his
      merge (commit 5a924a07f882: "Merge branches 'thermal-core' and
      'thermal-intel' of .git into next") of the thermal-core and
      thermal-intel branches was wrong.

      In thermal-core, commit 17e8351a7739 ("thermal: consistently use int for
      temperatures") converted the thermal layer to use "int" for
      temperatures.

      But in parallel, in the thermal-intel branch commit d0a12625d2ff
      ("thermal: Add Intel PCH thermal driver") added support for the intel
      PCH thermal sensor using the old interfaces that used "unsigned long"
      pointers.

      This resulted in warnings like this:

        drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization 
from incompatible pointer type [-Wincompatible-pointer-types]
          .get_temp = pch_thermal_get_temp,

        drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization

        drivers/thermal/intel_pch_thermal.c:186:19: note: (near initialization

      This fixes it.

      early_memunmap() has not been declared yet at this point in the .c file,
      nor by any explicitly included header files, we are depending on a
      transitive include of asm/early_ioremap.h to declare it, which is
      fragile.

      So instead, include this header explicitly.

      sys_membarrier(): system-wide memory barrier (generic, x86)

      Here is an implementation of a new system call, sys_membarrier(), which
      executes a memory barrier on all threads running on the system.  It is
      implemented by calling synchronize_sched().  It can be used to
      distribute the cost of user-space memory barriers asymmetrically by
      transforming pairs of memory barriers into pairs consisting of
      sys_membarrier() and a compiler barrier.  For synchronization primitives
      that distinguish between read-side and write-side (e.g.  userspace RCU
      [1], rwlocks), the read-side can be accelerated significantly by moving
      the bulk of the memory barrier overhead to the write-side.

      The existing applications of which I am aware that would be improved by
      this system call are as follows:

      * Through Userspace RCU library (http://urcu.so)
        - DNS server (Knot DNS) https://www.knot-dns.cz/
        - Network sniffer (http://netsniff-ng.org/)
        - Distributed object storage (https://sheepdog.github.io/sheepdog/)
        - User-space tracing (http://lttng.org)
        - Network storage system (https://www.gluster.org/)
        - Virtual routers 
(https://events.linuxfoundation.org/sites/events/files/slides/DPDK_RCU_0MQ.pdf)
        - Financial software (https://lkml.org/lkml/2015/3/23/189)

      Those projects use RCU in userspace to increase read-side speed and
      scalability compared to locking.  Especially in the case of RCU used by
      libraries, sys_membarrier can speed up the read-side by moving the bulk of
      the memory barrier cost to synchronize_rcu().

      * Direct users of sys_membarrier
        - core dotnet garbage collector 
(https://github.com/dotnet/coreclr/issues/198)

      Microsoft core dotnet GC developers are planning to use the mprotect()
      side-effect of issuing memory barriers through IPIs as a way to implement
      Windows FlushProcessWriteBuffers() on Linux.  They are referring to
      sys_membarrier in their github thread, specifically stating that
      sys_membarrier() is what they are looking for.

      To explain the benefit of this scheme, let's introduce two example 
threads:

      Thread A (non-frequent, e.g. executing liburcu synchronize_rcu())
      Thread B (frequent, e.g. executing liburcu
      rcu_read_lock()/rcu_read_unlock())

      In a scheme where all smp_mb() in thread A are ordering memory accesses
      with respect to smp_mb() present in Thread B, we can change each
      smp_mb() within Thread A into calls to sys_membarrier() and each
      smp_mb() within Thread B into compiler barriers "barrier()".

      Before the change, we had, for each smp_mb() pairs:

      Thread A                    Thread B
      previous mem accesses       previous mem accesses
      smp_mb()                    smp_mb()
      following mem accesses      following mem accesses

      After the change, these pairs become:

      Thread A                    Thread B
      prev mem accesses           prev mem accesses
      sys_membarrier()            barrier()
      follow mem accesses         follow mem accesses

      As we can see, there are two possible scenarios: either Thread B memory
      accesses do not happen concurrently with Thread A accesses (1), or they
      do (2).

      1) Non-concurrent Thread A vs Thread B accesses:

      Thread A                    Thread B
      prev mem accesses
      sys_membarrier()
      follow mem accesses
                                  prev mem accesses
                                  barrier()
                                  follow mem accesses

      In this case, thread B accesses will be weakly ordered. This is OK,
      because at that point, thread A is not particularly interested in
      ordering them with respect to its own accesses.

      2) Concurrent Thread A vs Thread B accesses

      Thread A                    Thread B
      prev mem accesses           prev mem accesses
      sys_membarrier()            barrier()
      follow mem accesses         follow mem accesses

      In this case, thread B accesses, which are ensured to be in program
      order thanks to the compiler barrier, will be "upgraded" to full
      smp_mb() by synchronize_sched().

      * Benchmarks

      On Intel Xeon E5405 (8 cores)
      (one thread is calling sys_membarrier, the other 7 threads are busy
      looping)

      1000 non-expedited sys_membarrier calls in 33s =3D 33 milliseconds/call.

      * User-space user of this system call: Userspace RCU library

      Both the signal-based and the sys_membarrier userspace RCU schemes
      permit us to remove the memory barrier from the userspace RCU
      rcu_read_lock() and rcu_read_unlock() primitives, thus significantly
      accelerating them. These memory barriers are replaced by compiler
      barriers on the read-side, and all matching memory barriers on the
      write-side are turned into an invocation of a memory barrier on all
      active threads in the process. By letting the kernel perform this
      synchronization rather than dumbly sending a signal to every process
      threads (as we currently do), we diminish the number of unnecessary wake
      ups and only issue the memory barriers on active threads. Non-running
      threads do not need to execute such barrier anyway, because these are
      implied by the scheduler context switches.

      Results in liburcu:

      Operations in 10s, 6 readers, 2 writers:

      memory barriers in reader:    1701557485 reads, 2202847 writes
      signal-based scheme:          9830061167 reads,    6700 writes
      sys_membarrier:               9952759104 reads,     425 writes
      sys_membarrier (dyn. check):  7970328887 reads,     425 writes

      The dynamic sys_membarrier availability check adds some overhead to
      the read-side compared to the signal-based scheme, but besides that,
      sys_membarrier slightly outperforms the signal-based scheme. However,
      this non-expedited sys_membarrier implementation has a much slower grace
      period than signal and memory barrier schemes.

      Besides diminishing the number of wake-ups, one major advantage of the
      membarrier system call over the signal-based scheme is that it does not
      need to reserve a signal. This plays much more nicely with libraries,
      and with processes injected into for tracing purposes, for which we
      cannot expect that signals will be unused by the application.

      An expedited version of this system call can be added later on to speed
      up the grace period. Its implementation will likely depend on reading
      the cpu_curr()->mm without holding each CPU's rq lock.

      This patch adds the system call to x86 and to asm-generic.

                    entry to and return from the system  call  (non-running  
threads
                    are de facto in such a state). This covers threads from all 
pro=E2=80=90
                    cesses running on the system.  This command returns 0.

             The flags argument needs to be 0. For future extensions.

             All memory accesses performed  in  program  order  from  each  
targeted
             thread is guaranteed to be ordered with respect to 
sys_membarrier(). If
             we use the semantic "barrier()" to represent a compiler barrier 
forcing
             memory  accesses  to  be performed in program order across the 
barrier,
             and smp_mb() to represent explicit memory barriers forcing full  
memory
             ordering  across  the barrier, we have the following ordering 
table for
             each pair of barrier(), sys_membarrier() and smp_mb():

             The pair ordering is detailed as (O: ordered, X: not ordered):

                                    barrier()   smp_mb() sys_membarrier()
                    barrier()          X           X            O
                    smp_mb()           X           O            O
                    sys_membarrier()   O           O            O

      RETURN VALUE
             On success, these system calls return zero.  On error, -1 is  
returned,
             and errno is set appropriately. For a given command, with flags
             argument set to 0, this system call is guaranteed to always return 
the
             same value until reboot.

      ERRORS
             ENOSYS System call is not implemented.

             EINVAL Invalid arguments.

      IB/ehca: Deprecate driver, move to staging, schedule deletion

      The ehca driver is only supported on IBM machines with a custom EBus.
      As they have opted to build their newer machines using more industry
      standard technology and haven't really been pushing EBus capable
      machines for a while, this driver can now safely be moved to the
      staging area and scheduled for eventual removal.  This plan was brought
      to IBM's attention and received their sign-off.

      Revert "writeback: plug writeback at a high level"

      This reverts commit d353d7587d02116b9732d5c06615aed75a4d3a47.

      Doing the block layer plug/unplug inside writeback_sb_inodes() is
      broken, because that function is actually called with a spinlock held:
      wb->list_lock, as pointed out by Chris Mason.

      Chris suggested just dropping and re-taking the spinlock around the
      blk_finish_plug() call (the plgging itself can happen under the
      spinlock), and that would technically work, but is just disgusting.

      We do something fairly similar - but not quite as disgusting because we
      at least have a better reason for it - in writeback_single_inode(), so
      it's not like the caller can depend on the lock being held over the
      call, but in this case there just isn't any good reason for that
      "release and re-take the lock" pattern.

      [ In general, we should really strive to avoid the "release and retake"
        pattern for locks, because in the general case it can easily cause
        subtle bugs when the caller caches any state around the call that
        might be invalidated by dropping the lock even just temporarily. ]

      But in this case, the plugging should be easy to just move up to the
      callers before the spinlock is taken, which should even improve the
      effectiveness of the plug.  So there is really no good reason to play
      games with locking here.

      I'll send off a test-patch so that Dave Chinner can verify that that
      plug movement works.  In the meantime this just reverts the problematic
      commit and adds a comment to the function so that we hopefully don't
      make this mistake again.

      ARM: 8431/1: fix alignement of __bug_table section entries

      On old ARM chips, unaligned accesses to memory are not trapped and

      arm/xen: Enable user access to the kernel before issuing a privcmd call

      When Xen is copying data to/from the guest it will check if the kernel
      has the right to do the access. If not, the hypercall will return an
      error.

      After the commit a5e090acbf545c0a3b04080f8a488b17ec41fe02 "ARM:
      software-based privileged-no-access support", the kernel can't access
      any longer the user space by default. This will result to fail on every
      hypercall made by the userspace (i.e via privcmd).

      We have to enable the userspace access and then restore the correct
      permission every time the privcmd is used to made an hypercall.

      I didn't find generic helpers to do a these operations, so the change
      is only arm32 specific.

      ARM: domains: add memory dependencies to get_domain/set_domain

      We need to have memory dependencies on get_domain/set_domain to avoid
      the compiler over-optimising these inline assembly instructions.

      Loads/stores must not be reordered across a set_domain(), so introduce
      a compiler barrier for that assembly.

      The value of get_domain() must not be cached across a set_domain(), but
      we still want to allow the compiler to optimise it away.  Introduce a
      dependency on current_thread_info()->cpu_domain to avoid this; the new
      memory clobber in set_domain() should therefore cause the compiler to
      re-load this.  The other advantage of using this is we should have its
      address in the register set already, or very soon after at most call
      sites.

      block: blkg_destroy_all() should clear q->root_blkg and ->root_rl.blkg

      While making the root blkg unconditional, ec13b1d6f0a0 ("blkcg: always
      create the blkcg_gq for the root blkcg") removed the part which clears
      q->root_blkg and ->root_rl.blkg during q exit.  This leaves the two
      pointers dangling after blkg_destroy_all().  blk-throttle exit path
      performs blkg traversals and dereferences ->root_blkg and can lead to
      the following oops.

      While the bug is a straigh-forward use-after-free bug, it is tricky to
      reproduce because blkg release is RCU protected and the rest of exit
      path usually finishes before RCU grace period.

      This patch fixes the bug by updating blkg_destro_all() to clear
      q->root_blkg and ->root_rl.blkg.

      block: Copy a user iovec if it includes gaps

      For drivers that don't support gaps in the SG lists handed to
      them we must bounce (copy the user buffers) and pass a bio that
      does not include gaps. This doesn't matter for any current user,
      but will help to allow iser which can't handle gaps to use the
      block virtual boundary instead of using driver-local bounce
      buffering when handling SG_IO commands.

      block: Refuse adding appending a gapped integrity page to a bio

      This is only theoretical at the moment given that the only
      subsystems that generate integrity payloads are the block layer
      itself and the scsi target (which generate well aligned integrity
      payloads). But when we will expose integrity meta-data to user-space,
      we'll need to refuse appending a page with a gap (if the queue
      virtual boundary is set).

      CIFS: fix type confusion in copy offload ioctl

      This might lead to local privilege escalation (code execution as
      kernel) for systems where the following conditions are met:

       - CONFIG_CIFS_SMB2 and CONFIG_CIFS_POSIX are enabled
       - a cifs filesystem is mounted where:
        - the mount option "vers" was used and set to a value >=2.0
        - the attacker has write access to at least one file on the filesystem

      To attack this, an attacker would have to guess the target_tcon
      pointer (but guessing wrong doesn't cause a crash, it just returns an
      error code) and win a narrow race.

      target: Attach EXTENDED_COPY local I/O descriptors to xcopy_pt_sess

      This patch is a >= v4.1 regression bug-fix where control CDB
      emulation logic in commit 38b57f82 now expects a se_cmd->se_sess
      pointer to exist when determining T10-PI support is to be exposed
      for initiator host ports.

      To address this bug, go ahead and add locally generated se_cmd
      descriptors for copy-offload block-copy to it's own stand-alone
      se_session nexus, while the parent EXTENDED_COPY se_cmd descriptor
      remains associated with it's originating se_cmd->se_sess nexus.

      target/qla2xxx: Honor max_data_sg_nents I/O transfer limit

      This patch adds an optional fabric driver provided SGL limit
      that target-core will honor as it's own internal I/O maximum
      transfer length limit, as exposed by EVPD=0xb0 block limits
      parameters.

      This is required for handling cases when host I/O transfer
      length exceeds the requested EVPD block limits maximum
      transfer length. The initial user of this logic is qla2xxx,
      so that we can avoid having to reject I/Os from some legacy
      FC hosts where EVPD=0xb0 parameters are not honored.

      When se_cmd payload length exceeds the provided limit in
      target_check_max_data_sg_nents() code, se_cmd->data_length +
      se_cmd->prot_length are reset with se_cmd->residual_count
      plus underflow bit for outgoing TFO response callbacks.
      It also checks for existing CDB level underflow + overflow
      and recalculates final residual_count as necessary.

      Note this patch currently assumes 1:1 mapping of PAGE_SIZE
      per struct scatterlist entry.

      As Peterz pointed out:

      | So the normal rules for changing task_struct::cpus_allowed are holding
      | both pi_lock and rq->lock, such that holding either stabilizes the mask.
      |
      | This is so that wakeup can happen without rq->lock and load-balance
      | without pi_lock.
      |
      | From this we already get the relaxation that we can omit acquiring
      | rq->lock if the task is not on the rq, because in that case
      | load-balancing will not apply to it.
      |
      | ** these are the rules currently tested in do_set_cpus_allowed() **
      |
      | Now, since __set_cpus_allowed_ptr() uses task_rq_lock() which
      | unconditionally acquires both locks, we could get away with holding just
      | rq->lock when on_rq for modification because that'd still exclude
      | __set_cpus_allowed_ptr(), it would also work against
      | __kthread_bind_mask() because that assumes !on_rq.
      |
      | That said, this is all somewhat fragile.
      |
      | Now, I don't think dropping rq->lock is quite as disastrous as it
      | usually is because !cpu_active at this point, which means load-balance
      | will not interfere, but that too is somewhat fragile.
      |
      | So we end up with a choice of two fragile..

      This patch fixes it by following the rules for changing
      task_struct::cpus_allowed with both pi_lock and rq->lock held.

      locking/qspinlock/x86: Fix performance regression under unaccelerated VMs

      Dave ran into horrible performance on a VM without PARAVIRT_SPINLOCKS
      set and Linus noted that the test-and-set implementation was retarded.

      One should spin on the variable with a load, not a RMW.

      While there, remove 'queued' from the name, as the lock isn't queued
      at all, but a simple test-and-set.

      Merge branch 'for-4.3/blkcg' of git://git.kernel.dk/linux-block

      Pull blk-cg updates from Jens Axboe:
       "A bit later in the cycle, but this has been in the block tree for a a
        while.  This is basically four patchsets from Tejun, that improve our
        buffered cgroup writeback.  It was dependent on the other cgroup
        changes, but they went in earlier in this cycle.

        Series 1 is set of 5 patches that has cgroup writeback updates:

         - bdi_writeback iteration fix which could lead to some wb's being
           skipped or repeated during e.g. sync under memory pressure.

         - Simplification of wb work wait mechanism.

         - Writeback tracepoints updated to report cgroup.

        Series 2 is is a set of updates for the CFQ cgroup writeback handling:

           cfq has always charged all async IOs to the root cgroup.  It didn't
           have much choice as writeback didn't know about cgroups and there
           was no way to tell who to blame for a given writeback IO.
           writeback finally grew support for cgroups and now tags each
           writeback IO with the appropriate cgroup to charge it against.

           This patchset updates cfq so that it follows the blkcg each bio is
           tagged with.  Async cfq_queues are now shared across cfq_group,
           which is per-cgroup, instead of per-request_queue cfq_data.  This
           makes all IOs follow the weight based IO resource distribution
           implemented by cfq.

           - Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff.

           - Other misc review points addressed, acks added and rebased.

        Series 3 is the blkcg policy cleanup patches:

           This patchset contains assorted cleanups for blkcg_policy methods
           and blk[c]g_policy_data handling.

           - alloc/free added for blkg_policy_data.  exit dropped.

           - alloc/free added for blkcg_policy_data.

           - blk-throttle's async percpu allocation is replaced with direct
             allocation.

           - all methods now take blk[c]g_policy_data instead of blkcg_gq or
             blkcg.

        And finally, series 4 is a set of patches cleaning up the blkcg stats
        handling:

          blkcg's stats have always been somwhat of a mess.  This patchset
          tries to improve the situation a bit.

           - The following patches added to consolidate blkcg entry point and
             blkg creation.  This is in itself is an improvement and helps
             colllecting common stats on bio issue.

           - per-blkg stats now accounted on bio issue rather than request
             completion so that bio based and request based drivers can behave
             the same way.  The issue was spotted by Vivek.

           - cfq-iosched implements custom recursive stats and blk-throttle
             implements custom per-cpu stats.  This patchset make blkcg core
             support both by default.

           - cfq-iosched and blk-throttle keep track of the same stats
             multiple times.  Unify them"

      drm/qxl: validate monitors config modes

      Due to some recent changes in
      drm_helper_probe_single_connector_modes_merge_bits(), old custom modes
      were not being pruned properly. In current kernels,
      drm_mode_validate_basic() is called to sanity-check each mode in the
      list. If the sanity-check passes, the mode's status gets set to to
      MODE_OK. In older kernels this check was not done, so old custom modes
      would still have a status of MODE_UNVERIFIED at this point, and would
      therefore be pruned later in the function.

      As a result of this new behavior, the list of modes for a device always
      includes every custom mode ever configured for the device, with the
      largest one listed first. Since desktop environments usually choose the
      first preferred mode when a hotplug event is emitted, this had the
      result of making it very difficult for the user to reduce the size of
      the display.

      The qxl driver did implement the mode_valid connector function, but it
      was empty. In order to restore the old behavior where old custom modes
      are pruned, we implement a proper mode_valid function for the qxl
      driver. This function now checks each mode against the last configured
      custom mode and the list of standard modes. If the mode doesn't match
      any of these, its status is set to MODE_BAD so that it will be pruned as
      expected.

      toshiba_acpi: Fix hotkeys registration on some toshiba models

      Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function
      for keymap choosing") changed the *setup_keyboard function to query for
      the Hotkey Event Type to help choose the correct keymap, but turns out
      that here are certain Toshiba models out there not implementing this
      feature, and thus, failing to continue the input device registration and
      leaving such laptops without hotkey support.

      This patch changes such check, and instead of returning an error if
      the Hotkey Event Type is not present, we simply inform userspace about it,
      changing the message printed from err to notice, making the function
      responsible for registering the input device to continue.

      This issue was found on a Toshiba Portege Z30-B, but there might be
      some other models out there affected by this regression as well.

      Now that the rockchip clock subsystem does clock gating with GPIO banks,
      these are no longer enabled once during probe and no longer stay enabled
      for eternity. When all these clocks are disabled, the parent clock 
pclk_peri
      might be disabled too, as no other child claims it. So, we need to add 
pclk_peri
      to the critical clocks.

      clk: rockchip: handle critical clocks after registering all clocks

      Currently the registration of critical clocks is done in the function
      shared between rk3066 and rk3188 clock trees. That results in them
      getting handled maybe before all of them are registered.

      Therefore move the critical clock handling down to the end of the soc-
      specific clock registration function, so that all clocks are registered
      before they're maybe handled as critical clock.

      dma-mapping: consolidate dma_set_mask

      Almost everyone implements dma_set_mask the same way, although some time
      that's hidden in ->set_dma_mask methods.

      This patch consolidates those into a common implementation that either
      calls ->set_dma_mask if present or otherwise uses the default
      implementation.  Some architectures used to only call ->set_dma_mask
      after the initial checks, and those instance have been fixed to do the
      full work.  h8300 implemented dma_set_mask bogusly as a no-ops and has
      been fixed.

      Unfortunately some architectures overload unrelated semantics like 
changing
      the dma_ops into it so we still need to allow for an architecture override
      for now.

      dma-mapping: consolidate dma_supported

      Most architectures just call into ->dma_supported, but some also return 1
      if the method is not present, or 0 if no dma ops are present (although
      that should never happeb). Consolidate this more broad version into
      common code.

      Also fix h8300 which inorrectly always returned 0, which would have been
      a problem if it's dma_set_mask implementation wasn't a similarly buggy
      noop.

      As a few architectures have much more elaborate implementations, we
      still allow for arch overrides.

      dma-mapping: cosolidate dma_mapping_error

      Currently there are three valid implementations of dma_mapping_error:

       (1) call ->mapping_error
       (2) check for a hardcoded error code
       (3) always return 0

      This patch provides a common implementation that calls ->mapping_error
      if present, then checks for DMA_ERROR_CODE if defined or otherwise
      returns 0.

      dma-mapping: consolidate dma_{alloc,free}_noncoherent

      Most architectures do not support non-coherent allocations and either
      define dma_{alloc,free}_noncoherent to their coherent versions or stub
      them out.

      Openrisc uses dma_{alloc,free}_attrs to implement them, and only Mips
      implements them directly.

      This patch moves the Openrisc version to common code, and handles the
      DMA_ATTR_NON_CONSISTENT case in the mips dma_map_ops instance.

      Note that actual non-coherent allocations require a dma_cache_sync
      implementation, so if non-coherent allocations didn't work on
      an architecture before this patch they still won't work after it.

      dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}

      Since 2009 we have a nice asm-generic header implementing lots of DMA API
      functions for architectures using struct dma_map_ops, but unfortunately
      it's still missing a lot of APIs that all architectures still have to
      duplicate.

      This series consolidates the remaining functions, although we still need
      arch opt outs for two of them as a few architectures have very
      non-standard implementations.

      This patch (of 5):

      The coherent DMA allocator works the same over all architectures 
supporting
      dma_map operations.

      This patch consolidates them and converges the minor differences:

       - the debug_dma helpers are now called from all architectures, including
         those that were previously missing them
       - dma_alloc_from_coherent and dma_release_from_coherent are now always
         called from the generic alloc/free routines instead of the ops
         dma-mapping-common.h always includes dma-coherent.h to get the 
defintions
         for them, or the stubs if the architecture doesn't support this feature
       - checks for ->alloc / ->free presence are removed.  There is only one
         magic instead of dma_map_ops without them (mic_dma_ops) and that one
         is x86 only anyway.

      Besides that only x86 needs special treatment to replace a default devices
      if none is passed and tweak the gfp_flags.  An optional arch hook is 
provided
      for that.

      mm: make sure all file VMAs have ->vm_ops set

      We rely on vma->vm_ops == NULL to detect anonymous VMA: see
      vma_is_anonymous(), but some drivers doesn't set ->vm_ops.

      As a result we can end up with anonymous page in private file mapping.
      That should not lead to serious misbehaviour, but nevertheless is wrong.

      Let's fix by setting up dummy ->vm_ops for file mmapping if f_op->mmap()
      didn't set its own.

      The patch also adds sanity check into __vma_link_rb(). It will help
      catch broken VMAs which inserted directly into mm_struct via
      insert_vm_struct().

      mm, mpx: add "vm_flags_t vm_flags" arg to do_mmap_pgoff()

      Add the additional "vm_flags_t vm_flags" argument to do_mmap_pgoff(),
      rename it to do_mmap(), and re-introduce do_mmap_pgoff() as a simple
      wrapper on top of do_mmap().  Perhaps we should update the callers of
      do_mmap_pgoff() and kill it later.

      This way mpx_mmap() can simply call do_mmap(vm_flags => VM_MPX) and do not
      play with vm internals.

      After this change mmap_region() has a single user outside of mmap.c,
      arch/tile/mm/elf.c:arch_setup_additional_pages().  It would be nice to
      change arch/tile/ and unexport mmap_region().

      ipc: convert invalid scenarios to use WARN_ON

      Considering Linus' past rants about the (ab)use of BUG in the kernel, I
      took a look at how we deal with such calls in ipc.  Given that any errors
      or corruption in ipc code are most likely contained within the set of
      processes participating in the broken mechanisms, there aren't really many
      strong fatal system failure scenarios that would require a BUG call.
      Also, if something is seriously wrong, ipc might not be the place for such
      a BUG either.

      1. For example, recently, a customer hit one of these BUG_ONs in shm
         after failing shm_lock().  A busted ID imho does not merit a BUG_ON,
         and WARN would have been better.

      2. MSG_COPY functionality of posix msgrcv(2) for checkpoint/restore.
         I don't see how we can hit this anyway -- at least it should be IS_ERR.
          The 'copy' arg from do_msgrcv is always set by calling prepare_copy()
         first and foremost.  We could also probably drop this check altogether.
          Either way, it does not merit a BUG_ON.

      3. No ->fault() callback for the fs getting the corresponding page --
         seems selfish to make the system unusable.

      the new buffer is at 0x46fe000000ULL, decompressor_gzip is using
      0xffffffb901ffffff as out_len.  gunzip in lib/zlib_inflate/inflate.c cap
      that len to 0x01ffffff and decompress fails later.

      We could hit this problem with crashkernel booting that uses kexec loading
      kernel above 4GiB.

      We have decompress_* support:
          1. inbuf[]/outbuf[] for kernel preboot.
          2. inbuf[]/flush() for initramfs
          3. fill()/flush() for initrd.
      This bug only affect kernel preboot path that use outbuf[].

      Add __decompress and take real out_buf_len for gunzip instead of guessing
      wrong buf size.

      sysctl: fix int -> unsigned long assignments in INT_MIN case

      The following

          if (val < 0)
              *lvalp = (unsigned long)-val;

      is incorrect because the compiler is free to assume -val to be positive
      and use a sign-extend instruction for extending the bit pattern.  This is
      a problem if val == INT_MIN:

          # echo -2147483648 >/proc/sys/dev/scsi/logging_level
          # cat /proc/sys/dev/scsi/logging_level

      kexec: export KERNEL_IMAGE_SIZE to vmcoreinfo

      In x86_64, since v2.6.26 the KERNEL_IMAGE_SIZE is changed to 512M, and
      accordingly the MODULES_VADDR is changed to 0xffffffffa0000000.  However,
      in v3.12 Kees Cook introduced kaslr to randomise the location of kernel.
      And the kernel text mapping addr space is enlarged from 512M to 1G.  That
      means now KERNEL_IMAGE_SIZE is variable, its value is 512M when kaslr
      support is not compiled in and 1G when kaslr support is compiled in.
      Accordingly the MODULES_VADDR is changed too to be:

          #define MODULES_VADDR    (__START_KERNEL_map + KERNEL_IMAGE_SIZE)

      So when kaslr is compiled in and enabled, the kernel text mapping addr
      space and modules vaddr space need be adjusted.  Otherwise makedumpfile
      will collapse since the addr for some symbols is not correct.

      Hence KERNEL_IMAGE_SIZE need be exported to vmcoreinfo and got in
      makedumpfile to help calculate MODULES_VADDR.

      kexec: align crash_notes allocation to make it be inside one physical page

      People reported that crash_notes in /proc/vmcore were corrupted and this
      cause crash kdump failure.  With code debugging and log we got the root
      cause.  This is because percpu variable crash_notes are allocated in 2
      vmalloc pages.  Currently percpu is based on vmalloc by default.  Vmalloc
      can't guarantee 2 continuous vmalloc pages are also on 2 continuous
      physical pages.  So when 1st kernel exports the starting address and size
      of crash_notes through sysfs like below:

      /sys/devices/system/cpu/cpux/crash_notes
      /sys/devices/system/cpu/cpux/crash_notes_size

      kdump kernel use them to get the content of crash_notes.  However the 2nd
      part may not be in the next neighbouring physical page as we expected if
      crash_notes are allocated accross 2 vmalloc pages.  That's why
      nhdr_ptr->n_namesz or nhdr_ptr->n_descsz could be very huge in
      update_note_header_size_elf64() and cause note header merging failure or
      some warnings.

      In this patch change to call __alloc_percpu() to passed in the align value
      by rounding crash_notes_size up to the nearest power of two.  This makes
      sure the crash_notes is allocated inside one physical page since
      sizeof(note_buf_t) in all ARCHS is smaller than PAGE_SIZE.  Meanwhile add
      a BUILD_BUG_ON to break compile if size is bigger than PAGE_SIZE since
      crash_notes definitely will be in 2 pages.  That need be avoided, and need
      be reported if it's unavoidable.

      kexec: split kexec_load syscall from kexec core code

      There are two kexec load syscalls, kexec_load another and kexec_file_load.
       kexec_file_load has been splited as kernel/kexec_file.c.  In this patch I
      split kexec_load syscall code to kernel/kexec.c.

      And add a new kconfig option KEXEC_CORE, so we can disable kexec_load and
      use kexec_file_load only, or vice verse.

      The original requirement is from Ted Ts'o, he want kexec kernel signature
      being checked with CONFIG_KEXEC_VERIFY_SIG enabled.  But kexec-tools use
      kexec_load syscall can bypass the checking.

      Vivek Goyal proposed to create a common kconfig option so user can compile
      in only one syscall for loading kexec kernel.  KEXEC/KEXEC_FILE selects
      KEXEC_CORE so that old config files still work.

      Because there's general code need CONFIG_KEXEC_CORE, so I updated all the
      architecture Kconfig with a new option KEXEC_CORE, and let KEXEC selects
      KEXEC_CORE in arch Kconfig.  Also updated general kernel code with to
      kexec_load syscall.

      fs: Don't dump core if the corefile would become world-readable.

      On a filesystem like vfat, all files are created with the same owner
      and mode independent of who created the file. When a vfat filesystem
      is mounted with root as owner of all files and read access for everyone,
      root's processes left world-readable coredumps on it (but other
      users' processes only left empty corefiles when given write access
      because of the uid mismatch).

      Given that the old behavior was inconsistent and insecure, I don't see
      a problem with changing it. Now, all processes refuse to dump core unless
      the resulting corefile will only be readable by their owner.

      fs: if a coredump already exists, unlink and recreate with O_EXCL

      It was possible for an attacking user to trick root (or another user) into
      writing his coredumps into an attacker-readable, pre-existing file using
      rename() or link(), causing the disclosure of secret data from the victim
      process' virtual memory.  Depending on the configuration, it was also
      possible to trick root into overwriting system files with coredumps.  Fix
      that issue by never writing coredumps into existing files.

      Requirements for the attack:
       - The attack only applies if the victim's process has a nonzero
         RLIMIT_CORE and is dumpable.
       - The attacker can trick the victim into coredumping into an
         attacker-writable directory D, either because the core_pattern is
         relative and the victim's cwd is attacker-writable or because an
         absolute core_pattern pointing to a world-writable directory is used.
       - The attacker has one of these:
        A: on a system with protected_hardlinks=0:
           execute access to a folder containing a victim-owned,
           attacker-readable file on the same partition as D, and the
           victim-owned file will be deleted before the main part of the attack
           takes place. (In practice, there are lots of files that fulfill
           this condition, e.g. entries in Debian's /var/lib/dpkg/info/.)
           This does not apply to most Linux systems because most distros set
           protected_hardlinks=1.
        B: on a system with protected_hardlinks=1:
           execute access to a folder containing a victim-owned,
           attacker-readable and attacker-writable file on the same partition
           as D, and the victim-owned file will be deleted before the main part
           of the attack takes place.
           (This seems to be uncommon.)
        C: on any system, independent of protected_hardlinks:
           write access to a non-sticky folder containing a victim-owned,
           attacker-readable file on the same partition as D
           (This seems to be uncommon.)

      The basic idea is that the attacker moves the victim-owned file to where
      he expects the victim process to dump its core.  The victim process dumps
      its core into the existing file, and the attacker reads the coredump from
      it.

      If the attacker can't move the file because he does not have write access
      to the containing directory, he can instead link the file to a directory
      he controls, then wait for the original link to the file to be deleted
      (because the kernel checks that the link count of the corefile is 1).

      A less reliable variant that requires D to be non-sticky works with link()
      and does not require deletion of the original link: link() the file into
      D, but then unlink() it directly before the kernel performs the link count
      check.

      On systems with protected_hardlinks=0, this variant allows an attacker to
      not only gain information from coredumps, but also clobber existing,
      victim-writable files with coredumps.  (This could theoretically lead to a
      privilege escalation.)

      kmod: handle UMH_WAIT_PROC from system unbound workqueue

      The UMH_WAIT_PROC handler runs in its own thread in order to make sure
      that waiting for the exec kernel thread completion won't block other
      usermodehelper queued jobs.

      On older workqueue implementations, worklets couldn't sleep without
      blocking the rest of the queue.  But now the workqueue subsystem handles
      that.  Khelper still had the older limitation due to its singlethread
      properties but we replaced it to system unbound workqueues.

      Those are affine to the current node and can block up to some number of
      instances.

      They are a good candidate to handle UMH_WAIT_PROC assuming that we have
      enough system unbound workers to handle lots of parallel usermodehelper
      jobs.

      kmod: use system_unbound_wq instead of khelper

      We need to launch the usermodehelper kernel threads with the widest
      affinity and this is partly why we use khelper.  This workqueue has
      unbound properties and thus a wide affinity inherited by all its children.

      Now khelper also has special properties that we aren't much interested in:
      ordered and singlethread.  There is really no need about ordering as all
      we do is creating kernel threads.  This can be done concurrently.  And
      singlethread is a useless limitation as well.

      The workqueue engine already proposes generic unbound workqueues that
      don't share these useless properties and handle well parallel jobs.

      The only worrysome specific is their affinity to the node of the current
      CPU.  It's fine for creating the usermodehelper kernel threads but those
      inherit this affinity for longer jobs such as requesting modules.

      This patch proposes to use these node affine unbound workqueues assuming

      kmod: add up-to-date explanations on the purpose of each asynchronous 
levels

      There seem to be quite some confusions on the comments, likely due to
      changes that came after them.

      Now since it's very non obvious why we have 3 levels of asynchronous code
      to implement usermodehelpers, it's important to comment in detail the
      reason of this layout.

      kmod: remove unecessary explicit wide CPU affinity setting

      Khelper is affine to all CPUs.  Now since it creates the
      call_usermodehelper_exec_[a]sync() kernel threads, those inherit the wide
      affinity.

      As such explicitly forcing a wide affinity from those kernel threads
      is like a no-op.

      Just remove it. It's needless and it breaks CPU isolation users who
      rely on workqueue affinity tuning.

      kmod: bunch of internal functions renames

      This patchset does a bunch of cleanups and converts khelper to use system
      unbound workqueues.  The 3 first patches should be uncontroversial.  The
      last 2 patches are debatable.

      Kmod creates kernel threads that perform userspace jobs and we want those
      to have a large affinity in order not to contend busy CPUs.  This is
      (partly) why we use khelper which has a wide affinity that the kernel
      threads it create can inherit from.  Now khelper is a dedicated workqueue
      that has singlethread properties which we aren't interested in.

      Hence those two debatable changes:

      _ We would like to use generic workqueues. System unbound workqueues are
        a very good candidate but they are not wide affine, only node affine.
        Now probably a node is enough to perform many parallel kmod jobs.

      _ We would like to remove the wait_for_helper kernel thread (UMH_WAIT_PROC
        handler) to use the workqueue. It means that if the workqueue blocks,
        and no other worker can take pending kmod request, we can be screwed.
        Now if we have 512 threads, this should be enough.

      This patch (of 5):

      Underscores on function names aren't much verbose to explain the purpose
      of a function.  And kmod has interesting such flavours.

      Lets rename the following functions:

      * __call_usermodehelper -> call_usermodehelper_exec_work
      * ____call_usermodehelper -> call_usermodehelper_exec_async
      * wait_for_helper -> call_usermodehelper_exec_sync

      kmod: correct documentation of return status of request_module

      If request_module() successfully runs modprobe, but modprobe exits with a
      non-zero status, then the return value from request_module() will be that
      (positive) error status.  So the return from request_module can be:

       negative errno
       zero for success
       positive exit code.

      hfs,hfsplus: cache pages correctly between bnode_create and bnode_free

      Pages looked up by __hfs_bnode_create() (called by hfs_bnode_create() and
      hfs_bnode_find() for finding or creating pages corresponding to an inode)
      are immediately kmap()'ed and used (both read and write) and kunmap()'ed,
      and should not be page_cache_release()'ed until hfs_bnode_free().

      This patch fixes a problem I first saw in July 2012: merely running "du"
      on a large hfsplus-mounted directory a few times on a reasonably loaded
      system would get the hfsplus driver all confused and complaining about
      B-tree inconsistencies, and generates a "BUG: Bad page state".  Most
      recently, I can generate this problem on up-to-date Fedora 22 with shipped
      kernel 4.0.5, by running "du /" (="/" + "/home" + "/mnt" + other smaller
      mounts) and "du /mnt" simultaneously on two windows, where /mnt is a
      lightly-used QEMU VM image of the full Mac OS X 10.9:

      $ df -i / /home /mnt
      Filesystem                  Inodes   IUsed      IFree IUse% Mounted on
      /dev/mapper/fedora-root    3276800  551665    2725135   17% /
      /dev/mapper/fedora-home   52879360  716221   52163139    2% /home
      /dev/nbd0p2             4294967295 1387818 4293579477    1% /mnt

      After applying the patch, I was able to run "du /" (60+ times) and "du
      /mnt" (150+ times) continuously and simultaneously for 6+ hours.

      There are many reports of the hfsplus driver getting confused under load
      and generating "BUG: Bad page state" or other similar issues over the
      years.  [1]

      The unpatched code [2] has always been wrong since it entered the kernel
      tree.  The only reason why it gets away with it is that the
      kmap/memcpy/kunmap follow very quickly after the page_cache_release() so
      the kernel has not had a chance to reuse the memory for something else,
      most of the time.

      The current RW driver appears to have followed the design and development
      of the earlier read-only hfsplus driver [3], where-by version 0.1 (Dec
      2001) had a B-tree node-centric approach to
      read_cache_page()/page_cache_release() per bnode_get()/bnode_put(),
      migrating towards version 0.2 (June 2002) of caching and releasing pages
      per inode extents.  When the current RW code first entered the kernel [2]
      in 2005, there was an REF_PAGES conditional (and "//" commented out code)
      to switch between B-node centric paging to inode-centric paging.  There
      was a mistake with the direction of one of the REF_PAGES conditionals in
      __hfs_bnode_create().  In a subsequent "remove debug code" commit [4], the
      read_cache_page()/page_cache_release() per bnode_get()/bnode_put() were
      removed, but a page_cache_release() was mistakenly left in (propagating
      the "REF_PAGES <-> !REF_PAGE" mistake), and the commented-out
      page_cache_release() in bnode_release() (which should be spanned by
      !REF_PAGES) was never enabled.

      fs/coda: fix readlink buffer overflow

      Dan Carpenter discovered a buffer overflow in the Coda file system
      readlink code.  A userspace file system daemon can return a 4096 byte
      result which then triggers a one byte write past the allocated readlink
      result buffer.

      This does not trigger with an unmodified Coda implementation because Coda
      has a 1024 byte limit for symbolic links, however other userspace file
      systems using the Coda kernel module could be affected.

      Although this is an obvious overflow, I don't think this has to be handled
      as too sensitive from a security perspective because the overflow is on
      the Coda userspace daemon side which already needs root to open Coda's
      kernel device and to mount the file system before we get to the point that
      links can be read.

      checkpatch: add some <foo>_destroy functions to NEEDLESS_IF tests

      Sergey Senozhatsky has modified several destroy functions that can
      now be called with NULL values.

       - kmem_cache_destroy()
       - mempool_destroy()
       - dma_pool_destroy()

      Update checkpatch to warn when those functions are preceded by an if.

      Update checkpatch to --fix all the calls too only when the code style
      form is using leading tabs.

      from:
        if (foo)
                <func>(foo);
      to:
        <func>(foo);

      lib/test_kasan.c: make kmalloc_oob_krealloc_less more correctly

      In kmalloc_oob_krealloc_less, I think it is better to test
      the size2 boundary.

      If we do not call krealloc, the access of position size1 will still cause
      out-of-bounds and access of position size2 does not.  After call krealloc,
      the access of position size2 cause out-of-bounds.  So using size2 is more
      correct.

      In __bitmap_parselist we can accept whitespaces on head or tail during
      every parsing procedure.  If input has valid ranges, there is no reason to
      reject the user.

      For example, bitmap_parselist(" 1-3, 5, ", &mask, nmaskbits).  After
      separating the string, we get " 1-3", " 5", and " ".  It's possible and
      reasonable to accept such string as long as the parsing result is correct.

      kernel/cred.c: remove unnecessary kdebug atomic reads

      Commit e0e817392b9a ("CRED: Add some configurable debugging [try #6]")
      added the kdebug mechanism to this file back in 2009.

      The kdebug macro calls no_printk which always evaluates arguments.

      Most of the kdebug uses have an unnecessary call of
        atomic_read(&cred->usage)

      Make the kdebug macro do nothing by defining it with
        do { if (0) no_printk(...); } while (0)
      when not enabled.

      include/linux/poison.h: fix LIST_POISON{1,2} offset

      Poison pointer values should be small enough to find a room in
      non-mmap'able/hardly-mmap'able space.  E.g.  on x86 "poison pointer space"
      is located starting from 0x0.  Given unprivileged users cannot mmap
      anything below mmap_min_addr, it should be safe to use poison pointers
      lower than mmap_min_addr.

      The current poison pointer values of LIST_POISON{1,2} might be too big for
      mmap_min_addr values equal or less than 1 MB (common case, e.g.  Ubuntu
      uses only 0x10000).  There is little point to use such a big value given
      the "poison pointer space" below 1 MB is not yet exhausted.  Changing it
      to a smaller value solves the problem for small mmap_min_addr setups.

      The values are suggested by Solar Designer:

      proc: change proc_subdir_lock to a rwlock

      The proc_subdir_lock spinlock is used to allow only one task to make
      change to the proc directory structure as well as looking up information
      in it.  However, the information lookup part can actually be entered by
      more than one task as the pde_get() and pde_put() reference count update
      calls in the critical sections are atomic increment and decrement
      respectively and so are safe with concurrent updates.

      The x86 architecture has already used qrwlock which is fair and other
      architectures like ARM are in the process of switching to qrwlock.  So
      unfairness shouldn't be a concern in that conversion.

      This patch changed the proc_subdir_lock to a rwlock in order to enable
      concurrent lookup. The following functions were modified to take a
      write lock:
       - proc_register()
       - remove_proc_entry()
       - remove_proc_subtree()

      The following functions were modified to take a read lock:
       - xlate_proc_name()
       - proc_lookup_de()
       - proc_readdir_de()

      A parallel /proc filesystem search with the "find" command (1000 threads)
      was run on a 4-socket Haswell-EX box (144 threads).  Before the patch, the
      parallel search took about 39s.  After the patch, the parallel find took
      only 25s, a saving of about 14s.

      The micro-benchmark that I used was artificial, but it was used to
      reproduce an exit hanging problem that I saw in real application.  In
      fact, only allow one task to do a lookup seems too limiting to me.

      procfs: always expose /proc/<pid>/map_files/ and make it readable

      Currently, /proc/<pid>/map_files/ is restricted to CAP_SYS_ADMIN, and is
      only exposed if CONFIG_CHECKPOINT_RESTORE is set.

      Each mapped file region gets a symlink in /proc/<pid>/map_files/
      corresponding to the virtual address range at which it is mapped.  The
      symlinks work like the symlinks in /proc/<pid>/fd/, so you can follow them
      to the backing file even if that backing file has been unlinked.

      Currently, files which are mapped, unlinked, and closed are impossible to
      stat() from userspace.  Exposing /proc/<pid>/map_files/ closes this
      functionality "hole".

      Not being able to stat() such files makes noticing and explicitly
      accounting for the space they use on the filesystem impossible.  You can
      work around this by summing up the space used by every file in the
      filesystem and subtracting that total from what statfs() tells you, but
      that obviously isn't great, and it becomes unworkable once your filesystem
      becomes large enough.

      This patch moves map_files/ out from behind CONFIG_CHECKPOINT_RESTORE, and
      adjusts the permissions enforced on it as follows:

      * proc_map_files_lookup()
      * proc_map_files_readdir()
      * map_files_d_revalidate()

        Remove the CAP_SYS_ADMIN restriction, leaving only the current
        restriction requiring PTRACE_MODE_READ. The information made
        available to userspace by these three functions is already
        available in /proc/PID/maps with MODE_READ, so I don't see any
        reason to limit them any further (see below for more detail).

      * proc_map_files_follow_link()

        This stub has been added, and requires that the user have
        CAP_SYS_ADMIN in order to follow the links in map_files/,
        since there was concern on LKML both about the potential for
        bypassing permissions on ancestor directories in the path to
        files pointed to, and about what happens with more exotic
        memory mappings created by some drivers (ie dma-buf).

      In older versions of this patch, I changed every permission check in
      the four functions above to enforce MODE_ATTACH instead of MODE_READ.
      This was an oversight on my part, and after revisiting the discussion
      it seems that nobody was concerned about anything outside of what is
      made possible by ->follow_link(). So in this version, I've left the
      checks for PTRACE_MODE_READ as-is.

      proc: export idle flag via kpageflags

      As noted by Minchan, a benefit of reading idle flag from /proc/kpageflags
      is that one can easily filter dirty and/or unevictable pages while
      estimating the size of unused memory.

      Note that idle flag read from /proc/kpageflags may be stale in case the
      page was accessed via a PTE, because it would be too costly to iterate
      over all page mappings on each /proc/kpageflags read to provide an
      up-to-date value.  To make sure the flag is up-to-date one has to read
      /sys/kernel/mm/page_idle/bitmap first.

      mm: introduce idle page tracking

      Knowing the portion of memory that is not used by a certain application or
      memory cgroup (idle memory) can be useful for partitioning the system
      efficiently, e.g.  by setting memory cgroup limits appropriately.
      Currently, the only means to estimate the amount of idle memory provided
      by the kernel is /proc/PID/{clear_refs,smaps}: the user can clear the
      access bit for all pages mapped to a particular process by writing 1 to
      clear_refs, wait for some time, and then count smaps:Referenced.  However,
      this method has two serious shortcomings:

       - it does not count unmapped file pages
       - it affects the reclaimer logic

      To overcome these drawbacks, this patch introduces two new page flags,
      Idle and Young, and a new sysfs file, /sys/kernel/mm/page_idle/bitmap.
      A page's Idle flag can only be set from userspace by setting bit in
      /sys/kernel/mm/page_idle/bitmap at the offset corresponding to the page,
      and it is cleared whenever the page is accessed either through page tables
      (it is cleared in page_referenced() in this case) or using the read(2)
      system call (mark_page_accessed()). Thus by setting the Idle flag for
      pages of a particular workload, which can be found e.g.  by reading
      /proc/PID/pagemap, waiting for some time to let the workload access its
      working set, and then reading the bitmap file, one can estimate the amount
      of pages that are not used by the workload.

      The Young page flag is used to avoid interference with the memory
      reclaimer.  A page's Young flag is set whenever the Access bit of a page
      table entry pointing to the page is cleared by writing to the bitmap file.
      If page_referenced() is called on a Young page, it will add 1 to its
      return value, therefore concealing the fact that the Access bit was
      cleared.

      Note, since there is no room for extra page flags on 32 bit, this feature
      uses extended page flags when compiled on 32 bit.

      mmu-notifier: add clear_young callback

      In the scope of the idle memory tracking feature, which is introduced by
      the following patch, we need to clear the referenced/accessed bit not only
      in primary, but also in secondary ptes.  The latter is required in order
      to estimate wss of KVM VMs.  At the same time we want to avoid flushing
      tlb, because it is quite expensive and it won't really affect the final
      result.

      Currently, there is no function for clearing pte young bit that would meet
      our requirements, so this patch introduces one.  To achieve that we have
      to add a new mmu-notifier callback, clear_young, since there is no method
      for testing-and-clearing a secondary pte w/o flushing tlb.  The new method
      is not mandatory and currently only implemented by KVM.

      hwpoison: use page_cgroup_ino for filtering by memcg

      Hwpoison allows to filter pages by memory cgroup ino.  Currently, it
      calls try_get_mem_cgroup_from_page to obtain the cgroup from a page and
      then its ino using cgroup_ino, but now we have a helper method for
      that, page_cgroup_ino, so use it instead.

      This patch also loosens the hwpoison memcg filter dependency rules - it
      makes it depend on CONFIG_MEMCG instead of CONFIG_MEMCG_SWAP, because
      hwpoison memcg filter does not require anything (nor it used to) from
      CONFIG_MEMCG_SWAP side.

      memcg: add page_cgroup_ino helper

      This patchset introduces a new user API for tracking user memory pages
      that have not been used for a given period of time.  The purpose of this
      is to provide the userspace with the means of tracking a workload's
      working set, i.e.  the set of pages that are actively used by the
      workload.  Knowing the working set size can be useful for partitioning the
      system more efficiently, e.g.  by tuning memory cgroup limits
      appropriately, or for job placement within a compute cluster.

      ==== USE CASES ====

      The unified cgroup hierarchy has memory.low and memory.high knobs, which
      are defined as the low and high boundaries for the workload working set
      size.  However, the working set size of a workload may be unknown or
      change in time.  With this patch set, one can periodically estimate the
      amount of memory unused by each cgroup and tune their memory.low and
      memory.high parameters accordingly, therefore optimizing the overall
      memory utilization.

      Another use case is balancing workloads within a compute cluster.  Knowing
      how much memory is not really used by a workload unit may help take a more
      optimal decision when considering migrating the unit to another node
      within the cluster.

      Also, as noted by Minchan, this would be useful for per-process reclaim
      (https://lwn.net/Articles/545668/). With idle tracking, we could reclaim 
idle
      pages only by smart user memory manager.

      ==== USER API ====

      The user API consists of two new files:

       * /sys/kernel/mm/page_idle/bitmap.  This file implements a bitmap where 
each
         bit corresponds to a page, indexed by PFN. When the bit is set, the
         corresponding page is idle. A page is considered idle if it has not 
been
         accessed since it was marked idle. To mark a page idle one should set 
the
         bit corresponding to the page by writing to the file. A value written 
to the
         file is OR-ed with the current bitmap value. Only user memory pages 
can be
         marked idle, for other page types input is silently ignored. Writing 
to this
         file beyond max PFN results in the ENXIO error. Only available when
         CONFIG_IDLE_PAGE_TRACKING is set.

         This file can be used to estimate the amount of pages that are not
         used by a particular workload as follows:

         1. mark all pages of interest idle by setting corresponding bits in the
            /sys/kernel/mm/page_idle/bitmap
         2. wait until the workload accesses its working set
         3. read /sys/kernel/mm/page_idle/bitmap and count the number of bits 
set

       * /proc/kpagecgroup.  This file contains a 64-bit inode number of the
         memory cgroup each page is charged to, indexed by PFN. Only available 
when
         CONFIG_MEMCG is set.

         This file can be used to find all pages (including unmapped file pages)
         accounted to a particular cgroup. Using 
/sys/kernel/mm/page_idle/bitmap, one
         can then estimate the cgroup working set size.

      For an example of using these files for estimating the amount of unused
      memory pages per each memory cgroup, please see the script attached
      below.

      ==== REASONING ====

      The reason to introduce the new user API instead of using
      /proc/PID/{clear_refs,smaps} is that the latter has two serious
      drawbacks:

       - it does not count unmapped file pages
       - it affects the reclaimer logic

      The new API attempts to overcome them both. For more details on how it
      is achieved, please see the comment to patch 6.

      ==== PATCHSET STRUCTURE ====

      The patch set is organized as follows:

       - patch 1 adds page_cgroup_ino() helper for the sake of
         /proc/kpagecgroup and patches 2-3 do related cleanup
       - patch 4 adds /proc/kpagecgroup, which reports cgroup ino each page is
         charged to
       - patch 5 introduces a new mmu notifier callback, clear_young, which is
         a lightweight version of clear_flush_young; it is used in patch 6
       - patch 6 implements the idle page tracking feature, including the
         userspace API, /sys/kernel/mm/page_idle/bitmap
       - patch 7 exports idle flag via /proc/kpageflags

      ==== SIMILAR WORKS ====

      Originally, the patch for tracking idle memory was proposed back in 2011
      by Michel Lespinasse (see http://lwn.net/Articles/459269/).  The main
      difference between Michel's patch and this one is that Michel implemented
      a kernel space daemon for estimating idle memory size per cgroup while
      this patch only provides the userspace with the minimal API for doing the
      job, leaving the rest up to the userspace.  However, they both share the
      same idea of Idle/Young page flags to avoid affecting the reclaimer logic.

      ==== PERFORMANCE EVALUATION ====

      SPECjvm2008 (https://www.spec.org/jvm2008/) was used to evaluate the
      performance impact introduced by this patch set.  Three runs were carried
      out:

       - base: kernel without the patch
       - patched: patched kernel, the feature is not used
       - patched-active: patched kernel, 1 minute-period daemon is used for
         tracking idle memory

      For tracking idle memory, idlememstat utility was used:

      This patch (of 8):

      Add page_cgroup_ino() helper to memcg.

      This function returns the inode number of the closest online ancestor of
      the memory cgroup a page is charged to.  It is required for exporting
      information about which page is charged to which cgroup to userspace,
      which will be introduced by a following patch.

      Update the zpool and compressor parameters to be changeable at runtime.
      When changed, a new pool is created with the requested zpool/compressor,
      and added as the current pool at the front of the pool list.  Previous
      pools remain in the list only to remove existing compressed pages from.
      The old pool(s) are removed once they become empty.

      zpool: add zpool_has_pool()

      This series makes creation of the zpool and compressor dynamic, so that
      they can be changed at runtime.  This makes using/configuring zswap
      easier, as before this zswap had to be configured at boot time, using boot
      params.

      This uses a single list to track both the zpool and compressor together,
      although Seth had mentioned an alternative which is to track the zpools
      and compressors using separate lists.  In the most common case, only a
      single zpool and single compressor, using one list is slightly simpler
      than using two lists, and for the uncommon case of multiple zpools and/or
      compressors, using one list is slightly less simple (and uses slightly
      more memory, probably) than using two lists.

      This patch (of 4):

      Add zpool_has_pool() function, indicating if the specified type of zpool
      is available (i.e.  zsmalloc or zbud).  This allows checking if a pool is
      available, without actually trying to allocate it, similar to
      crypto_has_alg().

      This is used by a following patch to zswap that enables the dynamic
      runtime creation of zswap zpools.

      tcp_cubic: better follow cubic curve after idle period

      Jana Iyengar found an interesting issue on CUBIC :

      The epoch is only updated/reset initially and when experiencing losses.
      The delta "t" of now - epoch_start can be arbitrary large after app idle
      as well as the bic_target. Consequentially the slope (inverse of
      ca->cnt) would be really large, and eventually ca->cnt would be
      lower-bounded in the end to 2 to have delayed-ACK slow-start behavior.

      This particularly shows up when slow_start_after_idle is disabled
      as a dangerous cwnd inflation (1.5 x RTT) after few seconds of idle
      time.

      Jana initial fix was to reset epoch_start if app limited,
      but Neal pointed out it would ask the CUBIC algorithm to recalculate the
      curve so that we again start growing steeply upward from where cwnd is
      now (as CUBIC does just after a loss). Ideally we'd want the cwnd growth
      curve to be the same shape, just shifted later in time by the amount of
      the idle period.

      wmi: Remove private %pUL implementation

      The work performed by wmi_gtoa is equivalent to simply sprintf(out,
      "%pUL", in), so one could replace its body by this. However, most
      users feed the result directly as a %s argument to some other function
      which also understands the %p extensions (they all ultimately use
      vsnprintf), so we can eliminate some stack buffers and quite a bit of
      code by just using %pUL directly.

      In wmi_dev_uevent I'm not sure whether there's room for a
      nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
      equivalent sprintf call.

      drm/i915: Don't try to use DDR DVFS on CHV when disabled in the BIOS

      If one disables DDR DVFS in the BIOS, Punit will apparently ignores
      all DDR DVFS request. Currently we assume that DDR DVFS is always
      operational, which leads to errors in dmesg when the DDR DVFS requests
      time out.

      Fix the problem by gently prodding Punit during driver load to find out
      whether it will respond to DDR DVFS requests. If the request times out,
      we assume that DDR DVFS has been permanenly disabled in the BIOS and
      no longer perster the Punit about it.

      Btrfs: remove unnecessary locking of cleaner_mutex to avoid deadlock

      After commmit e44163e17796 ("btrfs: explictly delete unused block groups
      in close_ctree and ro-remount"), added in the 4.3 merge window, we have
      calls to btrfs_delete_unused_bgs() while holding the cleaner_mutex.
      This can cause a deadlock with a concurrent block group relocation (when
      a filesystem balance or shrink operation is in progress for example)
      because btrfs_delete_unused_bgs() locks delete_unused_bgs_mutex and the
      relocation path locks first delete_unused_bgs_mutex and then it locks
      cleaner_mutex, resulting in a classic ABBA deadlock:

               CPU 0                                        CPU 1

      lock fs_info->cleaner_mutex

                                                 __btrfs_balance() || 
btrfs_shrink_device()
                                                   lock 
fs_info->delete_unused_bgs_mutex
                                                   btrfs_relocate_chunk()
                                                     
btrfs_relocate_block_group()
                                                       lock 
fs_info->cleaner_mutex
      btrfs_delete_unused_bgs()
        lock fs_info->delete_unused_bgs_mutex

      Fix this by not taking the cleaner_mutex before calling
      btrfs_delete_unused_bgs() because it's no longer needed after
      commit 67c5e7d464bc ("Btrfs: fix race between balance and unused block
      group deletion"). The mutex fs_info->delete_unused_bgs_mutex, the
      spinlock fs_info->unused_bgs_lock and a block group's spinlock are
      enough to get correct serialization between tasks running relocation
      and unused block group deletion (as well as between multiple tasks
      concurrently calling btrfs_delete_unused_bgs()).

      This issue was discussed (in the mailing list) during the review of
      the patch titled "btrfs: explictly delete unused block groups in
      close_ctree and ro-remount" and it was agreed that acquiring the
      cleaner mutex had to be dropped after the patch titled
      "Btrfs: fix race between balance and unused block group deletion"
      got merged (both patches were submitted at about the same time, but
      one landed in kernel 4.2 and the other in the 4.3 merge window).

      spi: bcm2835: BUG: fix wrong use of PAGE_MASK

      There is a bug in the alignment checking of transfers,
      that results in DMA not being used for un-aligned
      transfers that do not cross page-boundries, which is valid.

      This is due to a missconception of the meaning PAGE_MASK
      when implementing that check originally - (PAGE_SIZE - 1)
      should have been used instead.

      Also fixes a copy/paste error.

      powerpc/MSI: Fix race condition in tearing down MSI interrupts

      This fixes a race which can result in the same virtual IRQ number
      being assigned to two different MSI interrupts.  The most visible
      consequence of that is usually a warning and stack trace from the
      sysfs code about an attempt to create a duplicate entry in sysfs.

      The race happens when one CPU (say CPU 0) is disposing of an MSI
      while another CPU (say CPU 1) is setting up an MSI.  CPU 0 calls
      (for example) pnv_teardown_msi_irqs(), which calls
      msi_bitmap_free_hwirqs() to indicate that the MSI (i.e. its
      hardware IRQ number) is no longer in use.  Then, before CPU 0 gets
      to calling irq_dispose_mapping() to free up the virtal IRQ number,
      CPU 1 comes in and calls msi_bitmap_alloc_hwirqs() to allocate an
      MSI, and gets the same hardware IRQ number that CPU 0 just freed.
      CPU 1 then calls irq_create_mapping() to get a virtual IRQ number,
      which sees that there is currently a mapping for that hardware IRQ
      number and returns the corresponding virtual IRQ number (which is
      the same virtual IRQ number that CPU 0 was using).  CPU 0 then
      calls irq_dispose_mapping() and frees that virtual IRQ number.
      Now, if another CPU comes along and calls irq_create_mapping(), it
      is likely to get the virtual IRQ number that was just freed,
      resulting in the same virtual IRQ number apparently being used for
      two different hardware interrupts.

      To fix this race, we just move the call to msi_bitmap_free_hwirqs()
      to after the call to irq_dispose_mapping().  Since virq_to_hw()
      doesn't work for the virtual IRQ number after irq_dispose_mapping()
      has been called, we need to call it before irq_dispose_mapping() and
      remember the result for the msi_bitmap_free_hwirqs() call.

      The pattern of calling msi_bitmap_free_hwirqs() before
      irq_dispose_mapping() appears in 5 places under arch/powerpc, and
      appears to have originated in commit 05af7bd2d75e ("[POWERPC] MPIC
      U3/U4 MSI backend") from 2007.

      netlink, mmap: fix edge-case leakages in nf queue zero-copy

      When netlink mmap on receive side is the consumer of nf queue data,
      it can happen that in some edge cases, we write skb shared info into
      the user space mmap buffer:

      Assume a possible rx ring frame size of only 4096, and the network skb,
      which is being zero-copied into the netlink skb, contains page frags
      with an overall skb->len larger than the linear part of the netlink
      skb.

      skb_zerocopy(), which is generic and thus not aware of the fact that
      shared info cannot be accessed for such skbs then tries to write and
      fill frags, thus leaking kernel data/pointers and in some corner cases
      possibly writing out of bounds of the mmap area (when filling the
      last slot in the ring buffer this way).

      I.e. the ring buffer slot is then of status NL_MMAP_STATUS_VALID, has
      an advertised length larger than 4096, where the linear part is visible
      at the slot beginning, and the leaked sizeof(struct skb_shared_info)
      has been written to the beginning of the next slot (also corrupting
      the struct nl_mmap_hdr slot header incl. status etc), since skb->end
      points to skb->data + ring->frame_size - NL_MMAP_HDRLEN.

      The fix adds and lets __netlink_alloc_skb() take the actual needed
      linear room for the network skb + meta data into account. It's completely
      irrelevant for non-mmaped netlink sockets, but in case mmap sockets
      are used, it can be decided whether the available skb_tailroom() is
      really large enough for the buffer, or whether it needs to internally
      fallback to a normal alloc_skb().

      >From nf queue side, the information whether the destination port is
      an mmap RX ring is not really available without extra port-to-socket
      lookup, thus it can only be determined in lower layers i.e. when
      __netlink_alloc_skb() is called that checks internally for this. I
      chose to add the extra ldiff parameter as mmap will then still work:
      We have data_len and hlen in nfqnl_build_packet_message(), data_len
      is the full length (capped at queue->copy_range) for skb_zerocopy()
      and hlen some possible part of data_len that needs to be copied; the
      rem_len variable indicates the needed remaining linear mmap space.

      The only other workaround in nf queue internally would be after
      allocation time by f.e. cap'ing the data_len to the skb_tailroom()
      iff we deal with an mmap skb, but that would 1) expose the fact that
      we use a mmap skb to upper layers, and 2) trim the skb where we
      otherwise could just have moved the full skb into the normal receive
      queue.

      After the patch, in my test case the ring slot doesn't fit and therefore
      shows NL_MMAP_STATUS_COPY, where a full skb carries all the data and
      thus needs to be picked up via recv().

      netlink, mmap: don't walk rx ring on poll if receive queue non-empty

      In case of netlink mmap, there can be situations where received frames
      have to be placed into the normal receive queue. The ring buffer indicates
      this through NL_MMAP_STATUS_COPY, so the user is asked to pick them up
      via recvmsg(2) syscall, and to put the slot back to NL_MMAP_STATUS_UNUSED.

      Commit 0ef707700f1c ("netlink: rx mmap: fix POLLIN condition") changed
      polling, so that we walk in the worst case the whole ring through the
      new netlink_has_valid_frame(), for example, when the ring would have no
      NL_MMAP_STATUS_VALID, but at least one NL_MMAP_STATUS_COPY frame.

      Since we do a datagram_poll() already earlier to pick up a mask that could
      possibly contain POLLIN | POLLRDNORM already (due to NL_MMAP_STATUS_COPY),
      we can skip checking the rx ring entirely.

      In case the kernel is compiled with !CONFIG_NETLINK_MMAP, then all this is
      irrelevant anyway as netlink_poll() is just defined as datagram_poll().

      net: fec: add netif status check before set mac address

      There exist one issue by below case that case system hang:
      ifconfig eth0 down
      ifconfig eth0 hw ether 00:10:19:19:81:19

      After eth0 down, all fec clocks are gated off. In the 
.fec_set_mac_address()
      function, it will set new MAC address to registers, which causes system 
hang.

      So it needs to add netif status check to avoid registers access when 
clocks are
      gated off. Until eth0 up the new MAC address are wrote into related 
registers.

      V2:
      As Lucas Stach's suggestion, add a comment in the code to explain why it 
needed.

      Still for checking result of phy_connect() IS_ERR() makes perfect sense.

      So let's use combined check IS_ERR_OR_NULL() that covers both cases.

      ARM: uaccess: fix undefined instruction on ARMv7M/noMMU

      The use of get_domain() in copy_thread() results in an oops on
      ARMv7M/noMMU systems.  The thread cpu_domain value is only used when
      CONFIG_CPU_USE_DOMAINS is enabled, so there's no need to save the
      value in copy_thread() except when this is enabled, and this option
      will never be enabled on these platforms.

      net: ipv6: use common fib_default_rule_pref

      This switches IPv6 policy routing to use the shared
      fib_default_rule_pref() function of IPv4 and DECnet. It is also used in
      multicast routing for IPv4 as well as IPv6.

      The motivation for this patch is a complaint about iproute2 behaving
      inconsistent between IPv4 and IPv6 when adding policy rules: Formerly,
      IPv6 rules were assigned a fixed priority of 0x3FFF whereas for IPv4 the
      assigned priority value was decreased with each rule added.

      Since then all users of the default_pref field have been converted to
      assign the generic function fib_default_rule_pref(), fib_nl_newrule()
      may just use it directly instead. Therefore get rid of the function
      pointer altogether and make fib_default_rule_pref() static, as it's not
      used outside fib_rules.c anymore.

      ipv6: fix multipath route replace error recovery

      Problem:
      The ecmp route replace support for ipv6 in the kernel, deletes the
      existing ecmp route too early, ie when it installs the first nexthop.
      If there is an error in installing the subsequent nexthops, its too late
      to recover the already deleted existing route leaving the fib
      in an inconsistent state.

      This patch reduces the possibility of this by doing the following:
      a) Changes the existing multipath route add code to a two stage process:
        build rt6_infos + insert them
        ip6_route_add rt6_info creation code is moved into
        ip6_route_info_create.
      b) This ensures that most errors are caught during building rt6_infos
        and we fail early
      c) Separates multipath add and del code. Because add needs the special
        two stage mode in a) and delete essentially does not care.
      d) In any event if the code fails during inserting a route again, a
        warning is printed (This should be unlikely)

      Before the patch:

      intel_pstate: Fix user input of min/max to legal policy region

      In current code, max_perf_pct might be smaller than min_perf_pct
      by improper user input:

      $ grep . /sys/devices/system/cpu/intel_pstate/m*_perf_pct
      /sys/devices/system/cpu/intel_pstate/max_perf_pct:100
      /sys/devices/system/cpu/intel_pstate/min_perf_pct:100

      $ echo 80 > /sys/devices/system/cpu/intel_pstate/max_perf_pct

      $ grep . /sys/devices/system/cpu/intel_pstate/m*_perf_pct
      /sys/devices/system/cpu/intel_pstate/max_perf_pct:80
      /sys/devices/system/cpu/intel_pstate/min_perf_pct:100

      Fix this problem by 2 steps:
       1. Normalize the user input to [min_policy, max_policy].
       2. Make sure max_perf_pct>=min_perf_pct, suggested by Seiichi Ikarashi.

      ebpf: fix fd refcount leaks related to maps in bpf syscall

      We may already have gotten a proper fd struct through fdget(), so
      whenever we return at the end of an map operation, we need to call
      fdput(). However, each map operation from syscall side first probes
      CHECK_ATTR() to verify that unused fields in the bpf_attr union are
      zero.

      In case of malformed input, we return with error, but the lookup to
      the map_fd was already performed at that time, so that we return
      without an corresponding fdput(). Fix it by performing an fdget()
      only right before bpf_map_get(). The fdget() invocation on maps in
      the verifier is not affected.

      Watchdog: Fix parent of watchdog_devices

      /sys/class/watchdog/watchdogn/device/modalias can help to identify the
      driver/module for a given watchdog node. However, many wdt devices do not
      set their parent and so, we do not see an entry for device in sysfs for
      such devices.

      This patch fixes parent of watchdog_device so that
      /sys/class/watchdog/watchdogn/device is populated.

      Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not
      have any parent. Not sure, how we can identify driver for these devices.

      watchdog: add a driver to support SAMA5D4 watchdog timer

      From SAMA5D4, the watchdog timer is upgrated with a new feature,
      which is describled as in the datasheet, "WDT_MR can be written
      until a LOCKMR command is issued in WDT_CR".
      That is to say, as long as the bootstrap and u-boot don't issue
      a LOCKMR command, WDT_MR can be written more than once in the driver.

      So the SAMA5D4 watchdog driver's implementation is different from
      the at91sam9260 watchdog driver implemented in file at91sam9_wdt.c.
      The user application open the device file to enable the watchdog timer
      hardware, and close to disable it, and set the watchdog timer timeout
      by seting WDV and WDD fields of WDT_MR register, and ping the watchdog
      by issuing WDRSTT command to WDT_CR register with hard-coded key.

      Since commit ef90174f8210 ("watchdog: watchdog_core: Add watchdog
      registration deferral mechanism") there is no need to delay the call to
      watchdog_register_device any more. So simplify the registration code
      accordingly.

      Resetting wd_base to NULL can the also be dropped because nothing
      depends on it being NULL to signal probe failure any more. (The matching
      wd_base = NULL in .remove was missing, too.)

      watchdog: NXP LPC18xx Watchdog Timer Driver

      This commit adds support for the watchdog timer found in NXP LPC SoCs
      family, which includes LPC18xx/LPC43xx. Other SoCs in that family may
      share the same watchdog hardware.

      Watchdog driver registers a restart handler that will restart the system
      by performing an incorrect feed after ensuring the watchdog is enabled in
      reset mode.

      As watchdog cannot be disabled in hardware, driver's stop routine will
      regularly send a keepalive ping using a timer.

      watchdog: gpio-wdt: ping already at startup for always running devices

      During probe for an always-running watchdog a timer is setup to
      constantly ping the watchdog while the device is not open. The gpio to
      ping the watchdog is setup to inactive.

      For a watchdog with hw_algo = "toggle" this results in a ping depending
      on the initial state of the gpio, for hw_algo = "level" no ping is
      generated.

      Make sure that the first automatic ping is sent immediately and not only
      when the timer expires the first time. This makes the machine survive in
      case more than half of the watchdog timeout is already elapsed. (Which
      is very probable for the chip I'm faced with that has a timeout of one
      second.)

      watchdog: gpio-wdt: be more strict about hw_algo matching

      strncmp(algo, "toggle", 6) doesn't compare the trailing '\0' byte, so
      using

        hw_algo = "toggleboggle"

      is recognized the same way as

        hw_algo = "toggle"

      . While this doesn't introduce any problems for a device tree that
      sticks to the documented settings it's still ugly.

      Fix this by using strcmp to only match on "toggle" and "level".

      xen-netback: require fewer guest Rx slots when not using GSO

      Commit f48da8b14d04ca87ffcffe68829afd45f926ec6a (xen-netback: fix
      unlimited guest Rx internal queue and carrier flapping) introduced a
      regression.

      The PV frontend in IPXE only places 4 requests on the guest Rx ring.
      Since netback required at least (MAX_SKB_FRAGS + 1) slots, IPXE could
      not receive any packets.

      a) If GSO is not enabled on the VIF, fewer guest Rx slots are required
         for the largest possible packet.  Calculate the required slots
         based on the maximum GSO size or the MTU.

         This calculation of the number of required slots relies on
         1650d5455bd2 (xen-netback: always fully coalesce guest Rx packets)
         which present in 4.0-rc1 and later.

      b) Reduce the Rx stall detection to checking for at least one
         available Rx request.  This is fine since we're predominately
         concerned with detecting interfaces which are down and thus have
         zero available Rx requests.

      dax: update PMD fault handler with PMEM API

      As part of the v4.3 merge window the DAX code was updated by Matthew and
      Kirill to handle PMD pages.  Also as part of the v4.3 merge window we
      updated the DAX code to do proper PMEM flushing (commit 2765cfbb342c:
      "dax: update I/O path to do proper PMEM flushing").

      The additional code added by the DAX PMD patches also needs to be
      updated to properly use the PMEM API.  This ensures that after a PMD
      fault is handled the zeros written to the newly allocated pages are
      durable on the DIMMs.

      linux/dax.h is included to get rid of a bunch of sparse warnings.

      Pull inifiniband/rdma updates from Doug Ledford:
       "This is a fairly sizeable set of changes.  I've put them through a
        decent amount of testing prior to sending the pull request due to
        that.

        There are still a few fixups that I know are coming, but I wanted to
        go ahead and get the big, sizable chunk into your hands sooner rather
        than waiting for those last few fixups.

        Of note is the fact that this creates what is intended to be a
        temporary area in the drivers/staging tree specifically for some
        cleanups and additions that are coming for the RDMA stack.  We
        deprecated two drivers (ipath and amso1100) and are waiting to hear
        back if we can deprecate another one (ehca).  We also put Intel's new
        hfi1 driver into this area because it needs to be refactored and a
        transfer library created out of the factored out code, and then it and
        the qib driver and the soft-roce driver should all be modified to use
        that library.

        I expect drivers/staging/rdma to be around for three or four kernel
        releases and then to go away as all of the work is completed and final
        deletions of deprecated drivers are done.

        Summary of changes for 4.3:

         - Create drivers/staging/rdma
         - Move amso1100 driver to staging/rdma and schedule for deletion
         - Move ipath driver to staging/rdma and schedule for deletion
         - Add hfi1 driver to staging/rdma and set TODO for move to regular
           tree
         - Initial support for namespaces to be used on RDMA devices
         - Add RoCE GID table handling to the RDMA core caching code
         - Infrastructure to support handling of devices with differing read
           and write scatter gather capabilities
         - Various iSER updates
         - Kill off unsafe usage of global mr registrations
         - Update SRP driver
         - Misc  mlx4 driver updates
         - Support for the mr_alloc verb
         - Support for a netlink interface between kernel and user space cache
           daemon to speed path record queries and route resolution
         - Ininitial support for safe hot removal of verbs devices"

      pwm: NXP LPC18xx PWM/SCT driver

      This commit adds support for NXP LPC18xx PWM/SCT.

      NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State
      Configurable Timer (SCT) which can be configured as a Pulse Width
      Modulator. Other SoCs in that family may share the same hardware.

      The PWM supports a total of 16 channels, but only 15 can be simultaneously
      requested. There's only one period, global to all the channels, thus PWM
      driver will refuse setting different values to it, unless there's only one
      channel requested.

      drm/i915: Limit the number of loops for reading a split 64bit register

      In I915_READ64_2x32 we attempt to read a 64bit register using 2 32bit
      reads. Due to the nature of the registers we try to read in this manner,
      they may increment between the two instruction (e.g. a timestamp
      counter). To keep the result accurate, we repeat the read if we detect
      an overflow (i.e. the upper value varies). However, some hardware is just
      plain flaky and may endless loop as the the upper 32bits are not stable.
      Just give up after a couple of tries and report whatever we read last.

      v2: Use the most recent values when erring out on an unstable register.

      ceph: improve readahead for file holes

      When readahead encounters file holes, osd reply returns error -ENOENT,
      finish_read() skips adding pages to the the page cache. So readahead
      does not work for file holes. The fix is adding zero pages to the
      page cache when -ENOENT is returned.

      libceph: check data_len in ->alloc_msg()

      Only ->alloc_msg() should check data_len of the incoming message
      against the preallocated ceph_msg, doing it in the messenger is not
      right.  The contract is that either ->alloc_msg() returns a ceph_msg
      which will fit all of the portions of the incoming message, or it
      returns NULL and possibly sets skip, signaling whether NULL is due to
      an -ENOMEM.  ->alloc_msg() should be the only place where we make the
      skip/no-skip decision.

      I stumbled upon this while looking at con/osd ref counting.  Right now,
      if we get a non-extent message with a larger data portion than we are
      prepared for, ->alloc_msg() returns a ceph_msg, and then, when we skip
      it in the messenger, we don't put the con/osd ref acquired in
      ceph_con_in_msg_alloc() (which is normally put in process_message()),
      so this also fixes a memory leak.

      An existing BUG_ON in ceph_msg_data_cursor_init() ensures we don't
      corrupt random memory should a buggy ->alloc_msg() return an unfit
      ceph_msg.

      While at it, I changed the "unknown tid" dout() to a pr_warn() to make
      sure all skips are seen and unified format strings.

                                        // it tries to wake up a sender.
                                        tipc_write_space(sk)
                                                
wake_up_interruptible_sync_poll()
                        }

      After the sender thread is woke up it can gather control and perform
      an attempt to send a message. But if there is no enough place in send
      queue it will call link_schedule_user() function which puts a message
      of type SOCK_WAKEUP to the wakeup queue and put the sender to sleep.
      Thus the size of the queue actually is not changed and the while()
      loop never exits.

      The approach I proposed is to wake up only senders for which there is
      enough place in send queue so the described issue can't occur.
      Moreover the same approach is already used to wake up senders on
      unicast links.

      I have got into the issue on our product code but to reproduce the
      issue I changed a benchmark test application (from
      tipcutils/demos/benchmark) to perform the following scenario:
        1. Run 64 instances of test application (nodes). It can be done
           on the one physical machine.
        2. Each application connects to all other using TIPC sockets in
           RDM mode.
        3. When setup is done all nodes start simultaneously send
           broadcast messages.
        4. Everything hangs up.

      The issue is reproducible only when a congestion on broadcast link
      occurs. For example, when there are only 8 nodes it works fine since
      congestion doesn't occur. Send queue limit is 40 in my case (I use a
      critical importance level) and when 64 nodes send a message at the
      same moment a congestion occurs every time.

      net: dsa: bcm_sf2: Fix ageing conditions and operation

      The comparison check between cur_hw_state and hw_state is currently
      invalid because cur_hw_state is right shifted by G_MISTP_SHIFT, while
      hw_state is not, so we end-up comparing bits 2:0 with bits 7:5, which is
      going to cause an additional aging to occur. Fix this by not shifting
      cur_hw_state while reading it, but instead, mask the value with the
      appropriately shitfted bitmask.

      The other problem with the fast-ageing process is that we did not set
      the EN_AGE_DYNAMIC bit to request the ageing to occur for dynamically
      learned MAC addresses. Finally, write back 0 to the FAST_AGE_CTRL
      register to avoid leaving spurious bits sets from one operation to the
      other.

           in the ARM and Tegra SMMU drivers.

       "This has been a busy release for regmap.

        By far the biggest set of changes here are those from Markus Pargmann
        which implement support for block transfers in smbus devices.  This
        required quite a bit of refactoring but leaves us better able to
        handle odd restrictions that controllers may have and with better
        performance on smbus.

        Other new features include:

         - Fix interactions with lockdep for nested regmaps (eg, when a device
           using regmap is connected to a bus where the bus controller has a
           separate regmap).  Lockdep's default class identification is too
           crude to work without help.

         - Support for must write bitfield operations, useful for operations
           which require writing a bit to trigger them from Kuniori Morimoto.

         - Support for delaying during register patch application from Nariman
           Poushin.

      hexagon/time: Migrate to new 'set-state' interface

      Migrate hexagon driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      We weren't doing anything in the ->set_mode() callback. So, this patch
      doesn't provide any set-state callbacks.

      sb_edac: correctly fetch DIMM width on Ivy Bridge and Haswell

      dimm_dev_type has been incorrectly determined in sb_edac. This patch 
fixes it
      for Ivy Bridge and Haswell only since nothing like exists for Sandy 
Bridge.
      We tested this patch in multiple systems matching the results with the
      installed memory modules.

      sb_edac: look harder for DDRIO on Haswell systems

      In case the memory banks are populated so the first channel isn't used, 
the
      DDRIO PCI device won't be visible and it won't be possible to determine 
the
      memory type.

      zswap_get_swap_cache_page and read_swap_cache_async have pretty much the
      same code with only significant difference in return value and usage of
      swap_readpage.

      I a helper __read_swap_cache_async() with the common code.  Behavior
      change: now zswap_get_swap_cache_page will use radix_tree_maybe_preload
      instead radix_tree_preload.  Looks like, this wasn't changed only by the
      reason of code duplication.

      zram: unify error reporting

      Make zram syslog error reporting more consistent. We have random
      error levels in some places. For example, critical errors like
        "Error allocating memory for compressed page"
      and
        "Unable to allocate temp memory"
      are reported as KERN_INFO messages.

      a) Reassign error levels

      Error messages that directly affect zram
      functionality -- pr_err():

       Error allocating zram address table
       Error creating memory pool
       Decompression failed! err=%d, page=%u
       Unable to allocate temp memory
       Compression failed! err=%d
       Error allocating memory for compressed page: %u, size=%zu
       Cannot initialise %s compressing backend
       Error allocating disk queue for device %d
       Error allocating disk structure for device %d
       Error creating sysfs group for device %d
       Unable to register zram-control class
       Unable to get major number

      Messages that do not affect functionality, but user
      must be warned (because sysfs attrs will be removed in
      this particular case) -- pr_warn():

       %d (%s) Attribute %s (and others) will be removed. %s

      Messages that do not affect functionality and mostly are
      informative -- pr_info():

      zsmalloc: do not take class lock in zs_shrinker_count()

      We can avoid taking class ->lock around zs_can_compact() in
      zs_shrinker_count(), because the number that we return back is outdated
      in general case, by design.  We have different sources that are able to
      change class's state right after we return from zs_can_compact() --
      ongoing I/O operations, manually triggered compaction, or two of them
      happening simultaneously.

      We re-do this calculations during compaction on a per class basis
      anyway.

      zs_unregister_shrinker() will not return until we have an active
      shrinker, so classes won't unexpectedly disappear while
      zs_shrinker_count() iterates them.

      zsmalloc: partial page ordering within a fullness_list

      We want to see more ZS_FULL pages and less ZS_ALMOST_{FULL, EMPTY}
      pages.  Put a page with higher ->inuse count first within its
      ->fullness_list, which will give us better chances to fill up this page
      with new objects (find_get_zspage() return ->fullness_list head for new
      object allocation), so some zspages will become ZS_ALMOST_FULL/ZS_FULL
      quicker.

      It performs a trivial and cheap ->inuse compare which does not slow down
      zsmalloc and in the worst case keeps the list pages in no particular
      order.

      A more expensive solution could sort fullness_list by ->inuse count.

      zsmalloc: use shrinker to trigger auto-compaction

      Perform automatic pool compaction by a shrinker when system is getting
      tight on memory.

      User-space has a very little knowledge regarding zsmalloc fragmentation
      and basically has no mechanism to tell whether compaction will result in
      any memory gain.  Another issue is that user space is not always aware
      of the fact that system is getting tight on memory.  Which leads to very
      uncomfortable scenarios when user space may start issuing compaction
      'randomly' or from crontab (for example).  Fragmentation is not always
      necessarily bad, allocated and unused objects, after all, may be filled
      with the data later, w/o the need of allocating a new zspage.  On the
      other hand, we obviously don't want to waste memory when the system
      needs it.

      Compaction now has a relatively quick pool scan so we are able to
      estimate the number of pages that will be freed easily, which makes it
      possible to call this function from a shrinker->count_objects()
      callback.  We also abort compaction as soon as we detect that we can't
      free any pages any more, preventing wasteful objects migrations.

      zsmalloc: account the number of compacted pages

      Compaction returns back to zram the number of migrated objects, which is
      quite uninformative -- we have objects of different sizes so user space
      cannot obtain any valuable data from that number.  Change compaction to
      operate in terms of pages and return back to compaction issuer the
      number of pages that were freed during compaction.  So from now on we
      will export more meaningful value in zram<id>/mm_stat -- the number of
      freed (compacted) pages.

      This requires:
       (a) a rename of `num_migrated' to 'pages_compacted'
       (b) a internal API change -- return first_page's fullness_group from
           putback_zspage(), so we know when putback_zspage() did
           free_zspage().  It helps us to account compaction stats correctly.

      zsmalloc/zram: introduce zs_pool_stats api

      `zs_compact_control' accounts the number of migrated objects but it has
      a limited lifespan -- we lose it as soon as zs_compaction() returns back
      to zram.  It worked fine, because (a) zram had it's own counter of
      migrated objects and (b) only zram could trigger compaction.  However,
      this does not work for automatic pool compaction (not issued by zram).
      To account objects migrated during auto-compaction (issued by the
      shrinker) we need to store this number in zs_pool.

      Define a new `struct zs_pool_stats' structure to keep zs_pool's stats
      there.  It provides only `num_migrated', as of this writing, but it
      surely can be extended.

      A new zsmalloc zs_pool_stats() symbol exports zs_pool's stats back to
      caller.

      Use zs_pool_stats() in zram and remove `num_migrated' from zram_stats.

      zsmalloc: always keep per-class stats

      Always account per-class `zs_size_stat' stats.  This data will help us
      make better decisions during compaction.  We are especially interested
      in OBJ_ALLOCATED and OBJ_USED, which can tell us if class compaction
      will result in any memory gain.

      For instance, we know the number of allocated objects in the class, the
      number of objects being used (so we also know how many objects are not
      used) and the number of objects per-page.  So we can ensure if we have
      enough unused objects to form at least one ZS_EMPTY zspage during
      compaction.

      We calculate this value on per-class basis so we can calculate a total
      number of zspages that can be released.  Which is exactly what a
      shrinker wants to know.

      zsmalloc: drop unused variable `nr_to_migrate'

      This patchset tweaks compaction and makes it possible to trigger pool
      compaction automatically when system is getting low on memory.

      zsmalloc in some cases can suffer from a notable fragmentation and
      compaction can release some considerable amount of memory.  The problem
      here is that currently we fully rely on user space to perform compaction
      when needed.  However, performing zsmalloc compaction is not always an
      obvious thing to do.  For example, suppose we have a `idle' fragmented
      (compaction was never performed) zram device and system is getting low
      on memory due to some 3rd party user processes (gcc LTO, or firefox,
      etc.).  It's quite unlikely that user space will issue zpool compaction
      in this case.  Besides, user space cannot tell for sure how badly pool
      is fragmented; however, this info is known to zsmalloc and, hence, to a
      shrinker.

      This patch (of 7):

      __zs_compact() does not use `nr_to_migrate', drop it.

      Commit 1dfb059b9438 ("thp: reduce khugepaged freezing latency") fixed
      khugepaged to do not block a system suspend.  But the result is that it
      could not get interrupted before the given timeout because the condition
      for the wait event is "false".

      This patch puts back the original approach but it uses
      freezable_schedule_timeout_interruptible() instead of
      schedule_timeout_interruptible().  It does the right thing.  I am pretty
      sure that the freezable variant was not used in the original fix only
      because it was not available at that time.

      The regression has been there for ages.  It was not critical.  It just
      did the allocation throttling a little bit more aggressively.

      I found this problem when converting the kthread to kthread worker API
      and trying to understand the code.

      This bug is thought to have minimal userspace-visible impact.  Somebody
      could set a high alloc_sleep value by mistake, and then try to fix it
      back, but khugepaged would keep sleeping until the high value expires.

      mm/compaction: correct to flush migrated pages if pageblock skip happens

      We cache isolate_start_pfn before entering isolate_migratepages().  If
      pageblock is skipped in isolate_migratepages() due to whatever reason,
      cc->migrate_pfn can be far from isolate_start_pfn hence we flush pages
      that were freed.  For example, the following scenario can be possible:

      - assume order-9 compaction, pageblock order is 9
      - start_isolate_pfn is 0x200
      - isolate_migratepages()
        - skip a number of pageblocks
        - start to isolate from pfn 0x600
        - cc->migrate_pfn = 0x620
        - return
      - last_migrated_pfn is set to 0x200
      - check flushing condition
        - current_block_start is set to 0x600
        - last_migrated_pfn < current_block_start then do useless flush

      This wrong flush would not help the performance and success rate so this
      patch tries to fix it.  One simple way to know the exact position where
      we start to isolate migratable pages is that we cache it in
      isolate_migratepages() before entering actual isolation.  This patch
      implements that and fixes the problem.

      mm: use numa_mem_id() in alloc_pages_node()

      alloc_pages_node() might fail when called with NUMA_NO_NODE and
      __GFP_THISNODE on a CPU belonging to a memoryless node.  To make the
      local-node fallback more robust and prevent such situations, use
      numa_mem_id(), which was introduced for similar scenarios in the slab
      context.

      mm: unify checks in alloc_pages_node() and __alloc_pages_node()

      Perform the same debug checks in alloc_pages_node() as are done in
      __alloc_pages_node(), by making the former function a wrapper of the
      latter one.

      In addition to better diagnostics in DEBUG_VM builds for situations
      which have been already fatal (e.g.  out-of-bounds node id), there are
      two visible changes for potential existing buggy callers of
      alloc_pages_node():

      - calling alloc_pages_node() with any negative nid (e.g. due to arithmetic
        overflow) was treated as passing NUMA_NO_NODE and fallback to local 
node was
        applied. This will now be fatal.
      - calling alloc_pages_node() with an offline node will now be checked for
        DEBUG_VM builds. Since it's not fatal if the node has been previously 
online,
        and this patch may expose some existing buggy callers, change the 
VM_BUG_ON
        in __alloc_pages_node() to VM_WARN_ON.

      mm: rename alloc_pages_exact_node() to __alloc_pages_node()

      alloc_pages_exact_node() was introduced in commit 6484eb3e2a81 ("page
      allocator: do not check NUMA node ID when the caller knows the node is
      valid") as an optimized variant of alloc_pages_node(), that doesn't
      fallback to current node for nid == NUMA_NO_NODE.  Unfortunately the
      name of the function can easily suggest that the allocation is
      restricted to the given node and fails otherwise.  In truth, the node is
      only preferred, unless __GFP_THISNODE is passed among the gfp flags.

      The misleading name has lead to mistakes in the past, see for example
      commits 5265047ac301 ("mm, thp: really limit transparent hugepage
      allocation to local node") and b360edb43f8e ("mm, mempolicy:
      migrate_to_node should only migrate to node").

      Another issue with the name is that there's a family of
      alloc_pages_exact*() functions where 'exact' means exact size (instead
      of page order), which leads to more confusion.

      To prevent further mistakes, this patch effectively renames
      alloc_pages_exact_node() to __alloc_pages_node() to better convey that
      it's an optimized variant of alloc_pages_node() not intended for general
      usage.  Both functions get described in comments.

      It has been also considered to really provide a convenience function for
      allocations restricted to a node, but the major opinion seems to be that
      __GFP_THISNODE already provides that functionality and we shouldn't
      duplicate the API needlessly.  The number of users would be small
      anyway.

      Existing callers of alloc_pages_exact_node() are simply converted to
      call __alloc_pages_node(), with the exception of sba_alloc_coherent()
      which open-codes the check for NUMA_NO_NODE, so it is converted to use
      alloc_pages_node() instead.  This means it no longer performs some
      VM_BUG_ON checks, and since the current check for nid in
      alloc_pages_node() uses a 'nid < 0' comparison (which includes
      NUMA_NO_NODE), it may hide wrong values which would be previously
      exposed.

      Both differences will be rectified by the next patch.

      To sum up, this patch makes no functional changes, except temporarily
      hiding potentially buggy callers.  Restricting the checks in
      alloc_pages_node() is left for the next patch which can in turn expose
      more existing buggy callers.

      shmem: recalculate file inode when fstat

      Shmem uses shmem_recalc_inode to update i_blocks when it allocates page,
      undoes range or swaps.  But mm can drop clean page without notifying
      shmem.  This makes fstat sometimes return out-of-date block size.

      The problem can be partially solved when we add
      inode_operations->getattr which calls shmem_recalc_inode to update
      i_blocks for fstat.

      shmem_recalc_inode also updates counter used by statfs and
      vm_committed_as.  For them the situation is not changed.  They still
      suffer from the discrepancy after dropping clean page and before the
      function is called by aforementioned triggers.

      mm/hwpoison: don't try to unpoison containment-failed pages

      memory_failure() can be called at any page at any time, which means that
      we can't eliminate the possibility of containment failure.  In such case
      the best option is to leak the page intentionally (and never touch it
      later.)

      We have an unpoison function for testing, and it cannot handle such
      containment-failed pages, which results in kernel panic (visible with
      various calltraces.) So this patch suggests that we limit the
      unpoisonable pages to properly contained pages and ignore any other
      ones.

      Testers are recommended to keep in mind that there're un-unpoisonable
      pages when writing test programs.

        __soft_offline_page

isolate_lru_page in __soft_offline_page
        migrate_pages

      The second put_page() releases refcount held by isolate_lru_page() which
      will lead to unmap_and_move() releases the last refcount of page and w/
      mapcount still 1 since try_to_unmap() is not called if there is only one
      user map the page.  Anyway, the page refcount and mapcount will still
      mess if the page is mapped by multiple users.

      This race was introduced by commit 4491f71260 ("mm/memory-failure: set
      PageHWPoison before migrate_pages()"), which focuses on preventing the
      reuse of successfully migrated page.  Before this commit we prevent the
      reuse by changing the migratetype to MIGRATE_ISOLATE during soft
      offlining, which has the following problems, so simply reverting the
      commit is not a best option:

        1) it doesn't eliminate the reuse completely, because
           set_migratetype_isolate() can fail to set MIGRATE_ISOLATE to the
           target page if the pageblock of the page contains one or more
           unmovable pages (i.e.  has_unmovable_pages() returns true).

        2) the original code changes migratetype to MIGRATE_ISOLATE
           forcibly, and sets it to MIGRATE_MOVABLE forcibly after soft offline,
           regardless of the original migratetype state, which could impact
           other subsystems like memory hotplug or compaction.

      This patch moves PageSetHWPoison just after put_page() in
      unmap_and_move(), which closes up the reported race window and minimizes
      another race window b/w SetPageHWPoison and reallocation (which causes
      the reuse of soft-offlined page.) The latter race window still exists
      but it's acceptable, because it's rare and effectively the same as
      ordinary "containment failure" case even if it happens, so keep the
      window open is acceptable.

      mm/hwpoison: fix refcount of THP head page in no-injection case

      Hwpoison injection takes a refcount of target page and another refcount
      of head page of THP if the target page is the tail page of a THP.
      However, current code doesn't release the refcount of head page if the
      THP is not supported to be injected wrt hwpoison filter.

      Fix it by reducing the refcount of head page if the target page is the
      tail page of a THP and it is not supported to be injected.

      arm64: support initrd outside kernel linear map

      The use of mem= could leave part or all of the initrd outside of the
      kernel linear map.  This will lead to an error when unpacking the initrd

      relocates the initrd to be fully within the linear map.

      mm: add utility for early copy from unmapped ram

      When booting an arm64 kernel w/initrd using UEFI/grub, use of mem= will
      likely cut off part or all of the initrd.  This leaves it outside the
      kernel linear map which leads to failure when unpacking.  The x86 code
      has a similar need to relocate an initrd outside of mapped memory in
      some cases.

      The current x86 code uses early_memremap() to copy the original initrd
      from unmapped to mapped RAM.  This patchset creates a generic
      copy_from_early_mem() utility based on that x86 code and has arm64 and
      x86 share it in their respective initrd relocation code.

      This patch (of 3):

      In some early boot circumstances, it may be necessary to copy from RAM
      outside the kernel linear mapping to mapped RAM.  The need to relocate
      an initrd is one example in the x86 code.  This patch creates a helper
      function based on current x86 code.

      mm, compaction: skip compound pages by order in free scanner

      The compaction free scanner is looking for PageBuddy() pages and
      skipping all others.  For large compound pages such as THP or hugetlbfs,
      we can save a lot of iterations if we skip them at once using their
      compound_order().  This is generally unsafe and we can read a bogus
      value of order due to a race, but if we are careful, the only danger is
      skipping too much.

      When tested with stress-highalloc from mmtests on 4GB system with 1GB
      hugetlbfs pages, the vmstat compact_free_scanned count decreased by at
      least 15%.

      mm, compaction: always skip all compound pages by order in migrate scanner

      The compaction migrate scanner tries to skip THP pages by their order,
      to reduce number of iterations for pages it cannot isolate.  The check
      is only done if PageLRU() is true, which means it applies to THP pages,
      but not e.g.  hugetlbfs pages or any other non-LRU compound pages, which
      we have to iterate by base pages.

      This limitation comes from the assumption that it's only safe to read
      compound_order() when we have the zone's lru_lock and THP cannot be
      split under us.  But the only danger (after filtering out order values
      that are not below MAX_ORDER, to prevent overflows) is that we skip too
      much or too little after reading a bogus compound_order() due to a rare
      race.  This is the same reasoning as patch 99c0fd5e51c4 ("mm,
      compaction: skip buddy pages by their order in the migrate scanner")
      introduced for unsafely reading PageBuddy() order.

      After this patch, all pages are tested for PageCompound() and we skip
      them by compound_order().  The test is done after the test for
      balloon_page_movable() as we don't want to assume if balloon pages (or
      other pages with own isolation and migration implementation if a generic
      API gets implemented) are compound or not.

      When tested with stress-highalloc from mmtests on 4GB system with 1GB
      hugetlbfs pages, the vmstat compact_migrate_scanned count decreased by
      15%.

      mm, compaction: simplify handling restart position in free pages scanner

      Handling the position where compaction free scanner should restart
      (stored in cc->free_pfn) got more complex with commit e14c720efdd7 ("mm,
      compaction: remember position within pageblock in free pages scanner").
      Currently the position is updated in each loop iteration of
      isolate_freepages(), although it should be enough to update it only when
      breaking from the loop.  There's also an extra check outside the loop
      updates the position in case we have met the migration scanner.

      This can be simplified if we move the test for having isolated enough
      from the for-loop header next to the test for contention, and
      determining the restart position only in these cases.  We can reuse the
      isolate_start_pfn variable for this instead of setting cc->free_pfn
      directly.  Outside the loop, we can simply set cc->free_pfn to current
      value of isolate_start_pfn without any extra check.

      Also add a VM_BUG_ON to catch possible mistake in the future, in case we
      later add a new condition that terminates isolate_freepages_block()
      prematurely without also considering the condition in
      isolate_freepages().

      mm, compaction: more robust check for scanners meeting

      Assorted compaction cleanups and optimizations.  The interesting patches
      are 4 and 5.  In 4, skipping of compound pages in single iteration is
      improved for migration scanner, so it works also for !PageLRU compound
      pages such as hugetlbfs, slab etc.  Patch 5 introduces this kind of
      skipping in the free scanner.  The trick is that we can read
      compound_order() without any protection, if we are careful to filter out
      values larger than MAX_ORDER.  The only danger is that we skip too much.
      The same trick was already used for reading the freepage order in the
      migrate scanner.

      To demonstrate improvements of Patches 4 and 5 I've run stress-highalloc
      from mmtests, set to simulate THP allocations (including __GFP_COMP) on
      a 4GB system where 1GB was occupied by hugetlbfs pages.  I'll include
      just the relevant stats:

      With 5 iterations per patch, the results are still noisy, but we can see
      that Patch 4 does reduce migrate_scanned by 15% thanks to skipping the
      hugetlbfs pages at once.  Interestingly, free_scanned is also reduced
      and I have no idea why.  Patch 5 further reduces free_scanned as
      expected, by 15%.  Other stats are unaffected modulo noise.

      This patch (of 5):

      Compaction should finish when the migration and free scanner meet, i.e.
      they reach the same pageblock.  Currently however, the test in
      compact_finished() simply just compares the exact pfns, which may yield
      a false negative when the free scanner position is in the middle of a
      pageblock and the migration scanner reaches the begining of the same
      pageblock.

      This hasn't been a problem until commit e14c720efdd7 ("mm, compaction:
      remember position within pageblock in free pages scanner") allowed the
      free scanner position to be in the middle of a pageblock between
      invocations.  The hot-fix 1d5bfe1ffb5b ("mm, compaction: prevent
      infinite loop in compact_zone") prevented the issue by adding a special
      check in the migration scanner to satisfy the current detection of
      scanners meeting.

      However, the proper fix is to make the detection more robust.  This
      patch introduces the compact_scanners_met() function that returns true
      when the free scanner position is in the same or lower pageblock than
      the migration scanner.  The special case in isolate_migratepages()
      introduced by 1d5bfe1ffb5b is removed.

      mm: add support for __GFP_ZERO flag to dma_pool_alloc()

      Currently a call to dma_pool_alloc() with a ___GFP_ZERO flag returns a
      non-zeroed memory region.

      This patchset adds support for the __GFP_ZERO flag to dma_pool_alloc(),
      adds 2 wrapper functions for allocing zeroed memory from a pool, and
      provides a coccinelle script for finding & replacing instances of
      dma_pool_alloc() followed by memset(0) with a single dma_pool_zalloc()
      call.

      There was some concern that this always calls memset() to zero, instead
      of passing __GFP_ZERO into the page allocator.
      [https://lkml.org/lkml/2015/7/15/881]

      I ran a test on my system to get an idea of how often dma_pool_alloc()
      calls into pool_alloc_page().

      After Boot:       [   30.119863] alloc_calls:541, page_allocs:7
      After an hour:    [ 3600.951031] alloc_calls:9566, page_allocs:12
      After copying 1GB file onto a USB drive:
                [ 4260.657148] alloc_calls:17225, page_allocs:12

      It doesn't look like dma_pool_alloc() calls down to the page allocator
      very often (at least on my system).

      This patch (of 4):

      Currently the __GFP_ZERO flag is ignored by dma_pool_alloc().
      Make dma_pool_alloc() zero the memory if this flag is set.

      vmscan: fix increasing nr_isolated incurred by putback unevictable pages

      reclaim_clean_pages_from_list() assumes that shrink_page_list() returns
      number of pages removed from the candidate list.  But shrink_page_list()
      puts back mlocked pages without passing it to caller and without
      counting as nr_reclaimed.  This increases nr_isolated.

      To fix this, this patch changes shrink_page_list() to pass unevictable
      pages back to caller.  Caller will take care those pages.

      Minchan said:

      It fixes two issues.

      1. With unevictable page, cma_alloc will be successful.

      Exactly speaking, cma_alloc of current kernel will fail due to
      unevictable pages.

      2. fix leaking of NR_ISOLATED counter of vmstat

      With it, too_many_isolated works.  Otherwise, it could make hang until
      the process get SIGKILL.

      mm: vmscan: never isolate more pages than necessary

      If transparent huge pages are enabled, we can isolate many more pages
      than we actually need to scan, because we count both single and huge
      pages equally in isolate_lru_pages().

      Since commit 5bc7b8aca942d ("mm: thp: add split tail pages to shrink
      page list in page reclaim"), we scan all the tail pages immediately
      after a huge page split (see shrink_page_list()).  As a result, we can
      reclaim up to SWAP_CLUSTER_MAX * HPAGE_PMD_NR (512 MB) in one run!

      This is easy to catch on memcg reclaim with zswap enabled.  The latter
      makes swapout instant so that if we happen to scan an unreferenced huge
      page we will evict both its head and tail pages immediately, which is
      likely to result in excessive reclaim.

      bootmem: avoid freeing to bootmem after bootmem is done

      Bootmem isn't popular any more, but some architectures still use it, and
      freeing to bootmem after calling free_all_bootmem_core() can end up
      scribbling over random memory.  Instead, make sure the kernel generates
      a warning in this case by ensuring the node_bootmem_map field is
      non-NULL when are freeing or marking bootmem.

      An instance of this bug was just fixed in the tile architecture ("tile:
      use free_bootmem_late() for initrd") and catching this case more widely
      seems like a good thing.

      mem-hotplug: handle node hole when initializing numa_meminfo.

      When parsing SRAT, all memory ranges are added into numa_meminfo.  In
      numa_init(), before entering numa_cleanup_meminfo(), all possible memory
      ranges are in numa_meminfo.  And numa_cleanup_meminfo() removes all
      ranges over max_pfn or empty.

      But, this only works if the nodes are continuous.  Let's have a look at
      the following example:

      We have an SRAT like this:
      SRAT: Node 0 PXM 0 [mem 0x00000000-0x5fffffff]
      SRAT: Node 0 PXM 0 [mem 0x100000000-0x1ffffffffff]
      SRAT: Node 1 PXM 1 [mem 0x20000000000-0x3ffffffffff]
      SRAT: Node 4 PXM 2 [mem 0x40000000000-0x5ffffffffff] hotplug
      SRAT: Node 5 PXM 3 [mem 0x60000000000-0x7ffffffffff] hotplug
      SRAT: Node 2 PXM 4 [mem 0x80000000000-0x9ffffffffff] hotplug
      SRAT: Node 3 PXM 5 [mem 0xa0000000000-0xbffffffffff] hotplug
      SRAT: Node 6 PXM 6 [mem 0xc0000000000-0xdffffffffff] hotplug
      SRAT: Node 7 PXM 7 [mem 0xe0000000000-0xfffffffffff] hotplug

      On boot, only node 0,1,2,3 exist.

      And the numa_meminfo will look like this:
      numa_meminfo.nr_blks = 9
      1. on node 0: [0, 60000000]
      2. on node 0: [100000000, 20000000000]
      3. on node 1: [20000000000, 40000000000]
      4. on node 4: [40000000000, 60000000000]
      5. on node 5: [60000000000, 80000000000]
      6. on node 2: [80000000000, a0000000000]
      7. on node 3: [a0000000000, a0800000000]
      8. on node 6: [c0000000000, a0800000000]
      9. on node 7: [e0000000000, a0800000000]

      And numa_cleanup_meminfo() will merge 1 and 2, and remove 8,9 because the
      end address is over max_pfn, which is a0800000000.  But 4 and 5 are not
      removed because their end addresses are less then max_pfn.  But in fact,
      node 4 and 5 don't exist.

      In a word, numa_cleanup_meminfo() is not able to handle holes between 
nodes.

      Since memory ranges in node 4 and 5 are in numa_meminfo, in
      numa_register_memblks(), node 4 and 5 will be mistakenly set to online.

      If you run lscpu, it will show:
      NUMA node0 CPU(s):     0-14,128-142
      NUMA node1 CPU(s):     15-29,143-157
      NUMA node2 CPU(s):
      NUMA node3 CPU(s):
      NUMA node4 CPU(s):     62-76,190-204
      NUMA node5 CPU(s):     78-92,206-220

      In this patch, we use memblock_overlaps_region() to check if ranges in
      numa_meminfo overlap with ranges in memory_block.  Since memory_block
      contains all available memory at boot time, if they overlap, it means the
      ranges exist.  If not, then remove them from numa_meminfo.

      After this patch, lscpu will show:
      NUMA node0 CPU(s):     0-14,128-142
      NUMA node1 CPU(s):     15-29,143-157
      NUMA node4 CPU(s):     62-76,190-204
      NUMA node5 CPU(s):     78-92,206-220

      memblock_overlaps_region() checks if the given memblock region
      intersects a region in memblock.  If so, it returns the index of the

      But its only caller is memblock_is_region_reserved(), and it returns 0

      mm: madvise allow remove operation for hugetlbfs

      Now that we have hole punching support for hugetlbfs, we can also
      support the MADV_REMOVE interface to it.

      hugetlbfs: add hugetlbfs_fallocate()

      This is based on the shmem version, but it has diverged quite a bit.  We
      have no swap to worry about, nor the new file sealing.  Add
      synchronication via the fault mutex table to coordinate page faults,
      fallocate allocation and fallocate hole punch.

      What this allows us to do is move physical memory in and out of a
      hugetlbfs file without having it mapped.  This also gives us the ability
      to support MADV_REMOVE since it is currently implemented using
      fallocate().  MADV_REMOVE lets madvise() remove pages from the middle of
      a hugetlbfs file, which wasn't possible before.

      hugetlbfs fallocate only operates on whole huge pages.

      Based on code by Dave Hansen.

      mm/hugetlb: vma_has_reserves() needs to handle fallocate hole punch

      In vma_has_reserves(), the current assumption is that reserves are
      always present for shared mappings.  However, this will not be the case
      with fallocate hole punch.  When punching a hole, the present page will
      be deleted as well as the region/reserve map entry (and hence any
      reservation).  vma_has_reserves is passed "chg" which indicates whether
      or not a region/reserve map is present.  Use this to determine if
      reserves are actually present or were removed via hole punch.

      hugetlbfs: truncate_hugepages() takes a range of pages

      Modify truncate_hugepages() to take a range of pages (start, end)
      instead of simply start.  If an end value of LLONG_MAX is passed, the
      current "truncate" functionality is maintained.  Existing callers are
      modified to pass LLONG_MAX as end of range.  By keying off end ==
      LLONG_MAX, the routine behaves differently for truncate and hole punch.
      Page removal is now synchronized with page allocation via faults by
      using the fault mutex table.  The hole punch case can experience the
      rare region_del error and must handle accordingly.

      Add the routine hugetlb_fix_reserve_counts to fix up reserve counts in
      the case where region_del returns an error.

      Since the routine handles more than just the truncate case, it is
      renamed to remove_inode_hugepages().  To be consistent, the routine
      truncate_huge_page() is renamed remove_huge_page().

      Downstream of remove_inode_hugepages(), the routine
      hugetlb_unreserve_pages() is also modified to take a range of pages.
      hugetlb_unreserve_pages is modified to detect an error from region_del and
      pass it back to the caller.

      Modify the existing hugetlb_vmtruncate_list() routine to take a

      mm/hugetlb: add region_del() to delete a specific range of entries

      fallocate hole punch will want to remove a specific range of pages.  The
      existing region_truncate() routine deletes all region/reserve map
      entries after a specified offset.  region_del() will provide this same
      functionality if the end of region is specified as LONG_MAX.  Hence,
      region_del() can replace region_truncate().

      Unlike region_truncate(), region_del() can return an error in the rare
      case where it can not allocate memory for a region descriptor.  This
      ONLY happens in the case where an existing region must be split.
      Current callers passing LONG_MAX as end of range will never experience
      this error and do not need to deal with error handling.  Future callers
      of region_del() (such as fallocate hole punch) will need to handle this
      error.

      mm/hugetlb: add cache of descriptors to resv_map for region_add

      hugetlbfs is used today by applications that want a high degree of
      control over huge page usage.  Often, large hugetlbfs files are used to
      map a large number huge pages into the application processes.  The
      applications know when page ranges within these large files will no
      longer be used, and ideally would like to release them back to the
      subpool or global pools for other uses.  The fallocate() system call
      provides an interface for preallocation and hole punching within files.
      This patch set adds fallocate functionality to hugetlbfs.

      fallocate hole punch will want to remove a specific range of pages.
      When pages are removed, their associated entries in the region/reserve
      map will also be removed.  This will break an assumption in the
      region_chg/region_add calling sequence.  If a new region descriptor must
      be allocated, it is done as part of the region_chg processing.  In this
      way, region_add can not fail because it does not need to attempt an
      allocation.

      To prepare for fallocate hole punch, create a "cache" of descriptors
      that can be used by region_add if necessary.  region_chg will ensure
      there are sufficient entries in the cache.  It will be necessary to
      track the number of in progress add operations to know a sufficient
      number of descriptors reside in the cache.  A new routine region_abort
      is added to adjust this in progress count when add operations are
      aborted.  vma_abort_reservation is also added for callers creating
      reservations with vma_needs_reservation/vma_commit_reservation.

      mm: rename and move get/set_freepage_migratetype

      The pair of get/set_freepage_migratetype() functions are used to cache
      pageblock migratetype for a page put on a pcplist, so that it does not
      have to be retrieved again when the page is put on a free list (e.g.
      when pcplists become full).  Historically it was also assumed that the
      value is accurate for pages on freelists (as the functions' names
      unfortunately suggest), but that cannot be guaranteed without affecting
      various allocator fast paths.  It is in fact not needed and all such
      uses have been removed.

      The last remaining (but pointless) usage related to pages of freelists
      is in move_freepages(), which this patch removes.

      To prevent further confusion, rename the functions to
      get/set_pcppage_migratetype() and expand their description.  Since all
      the users are now in mm/page_alloc.c, move the functions there from the
      shared header.

      mm, page_isolation: remove bogus tests for isolated pages

      The __test_page_isolated_in_pageblock() is used to verify whether all
      pages in pageblock were either successfully isolated, or are hwpoisoned.
      Two of the possible state of pages, that are tested, are however bogus
      and misleading.

      Both tests rely on get_freepage_migratetype(page), which however has no
      guarantees about pages on freelists.  Specifically, it doesn't guarantee
      that the migratetype returned by the function actually matches the
      migratetype of the freelist that the page is on.  Such guarantee is not
      its purpose and would have negative impact on allocator performance.

      The first test checks whether the freepage_migratetype equals
      MIGRATE_ISOLATE, supposedly to catch races between page isolation and
      allocator activity.  These races should be fixed nowadays with
      51bb1a4093 ("mm/page_alloc: add freepage on isolate pageblock to correct
      buddy list") and related patches.  As explained above, the check
      wouldn't be able to catch them reliably anyway.  For the same reason
      false positives can happen, although they are harmless, as the
      move_freepages() call would just move the page to the same freelist it's
      already on.  So removing the test is not a bug fix, just cleanup.  After
      this patch, we assume that all PageBuddy pages are on the correct
      freelist and that the races were really fixed.  A truly reliable
      verification in the form of e.g.  VM_BUG_ON() would be complicated and
      is arguably not needed.

      The second test (page_count(page) == 0 && get_freepage_migratetype(page)
      == MIGRATE_ISOLATE) is probably supposed (the code comes from a big
      memory isolation patch from 2007) to catch pages on MIGRATE_ISOLATE
      pcplists.  However, pcplists don't contain MIGRATE_ISOLATE freepages
      nowadays, those are freed directly to free lists, so the check is
      obsolete.  Remove it as well.

      lib/show_mem.c: correct reserved memory calculation

      CMA reserved memory is not part of total reserved memory.  Currently
      when we print the total reserve memory it considers cma as part of

      get negative values & while printing we print as unsigned and we will
      get a very large value.

      memcg: move memcg_proto_active from sock.h

      The only user is sock_update_memcg which is living in memcontrol.c so it
      doesn't make much sense to pollute sock.h by this inline helper.  Move it
      to memcontrol.c and open code it into its only caller.

      memcg, tcp_kmem: check for cg_proto in sock_update_memcg

      sk_prot->proto_cgroup is allowed to return NULL but sock_update_memcg
      doesn't check for NULL.  The function relies on the mem_cgroup_is_root
      check because we shouldn't get NULL otherwise because mem_cgroup_from_task
      will always return !NULL.

      All other callers are checking for NULL and we can safely replace
      mem_cgroup_is_root() check by cg_proto != NULL which will be more
      straightforward (proto_cgroup returns NULL for the root memcg already).

      memcg: export struct mem_cgroup

      mem_cgroup structure is defined in mm/memcontrol.c currently which means
      that the code outside of this file has to use external API even for
      trivial access stuff.

      This patch exports mm_struct with its dependencies and makes some of the
      exported functions inlines.  This even helps to reduce the code size a bit
      (make defconfig + CONFIG_MEMCG=y)

        text            data    bss     dec              hex    filename

      This is not much (370B) but better than nothing.

      We also save a function call in some hot paths like callers of
      mem_cgroup_count_vm_event which is used for accounting.

      The patch doesn't introduce any functional changes.

      sparc32: do not include swap.h from pgtable_32.h

      "memcg: export struct mem_cgroup" will add includes into
      linux/memcontrol.h which lead to further header dependency issues as
      reported by Guenter Roeck:

        In file included from include/linux/highmem.h:7:0,
                         from include/linux/bio.h:23,
                         from include/linux/writeback.h:192,
                         from include/linux/memcontrol.h:30,
                         from include/linux/swap.h:8,
                         from ./arch/sparc/include/asm/pgtable_32.h:17,
                         from ./arch/sparc/include/asm/pgtable.h:6,
                         from arch/sparc/kernel/traps_32.c:23:
        include/linux/mm.h: In function 'is_vmalloc_addr':
        include/linux/mm.h:371:17: error: 'VMALLOC_START' undeclared (first use

        include/linux/mm.h:371:17: note: each undeclared identifier is reported

        include/linux/mm.h: In function 'maybe_mkwrite':
        include/linux/mm.h:556:3: error: implicit declaration of function 
'pte_mkwrite'

      The issue is that pgtable_32.h depends on swap.h to get swap_entry_t but
      that goes all the way down to linux/mm.h which wants to have VMALLOC_*
      which is defined later in pgtable_32.h, though.

      swap_entry_t is defined in include/mm_types.h so it should be sufficient
      to include this header without more dependencies.

      fs: do not prefault sys_write() user buffer pages

      === Short summary ====

      iov_iter_fault_in_readable() works around a really rare case and we can
      avoid the deadlock it addresses in another way: disable page faults and
      work around copy failures by faulting after the copy in a slow path
      instead of before in a hot one.

      I have a little microbenchmark that does repeated, small writes to tmpfs.
      This patch speeds that micro up by 6.2%.

      === Long version ===

      When doing a sys_write() we have a source buffer in userspace and then a
      target file page.

      If both of those are the same physical page, there is a potential deadlock
      that we avoid.  It would happen something like this:

      1. We start the write to the file
      2. Allocate page cache page and set it !Uptodate
      3. Touch the userspace buffer to copy in the user data
      4. Page fault (since source of the write not yet mapped)
      5. Page fault code tries to lock the page and deadlocks

      (more details on this below)

      To avoid this, we prefault the page to guarantee that this fault does not
      occur.  But, this prefault comes at a cost.  It is one of the most
      expensive things that we do in a hot write() path (especially if we
      compare it to the read path).  It is working around a pretty rare case.

      To fix this, it's pretty simple.  We move the "prefault" code to run after
      we attempt the copy.  We explicitly disable page faults _during_ the copy,
      detect the copy failure, then execute the "prefault" ouside of where the
      page lock needs to be held.

      iov_iter_copy_from_user_atomic() actually already has an implicit
      pagefault_disable() inside of it (at least on x86), but we add an explicit
      one.  I don't think we can depend on every kmap_atomic() implementation to
      pagefault_disable() for eternity.

      ===================================================

      The stack trace when this happens looks like this:

        wait_on_page_bit_killable+0xc0/0xd0
        __lock_page_or_retry+0x84/0xa0
        filemap_fault+0x1ed/0x3d0
        __do_fault+0x41/0xc0
        handle_mm_fault+0x9bb/0x1210
        __do_page_fault+0x17f/0x3d0
        do_page_fault+0xc/0x10
        page_fault+0x22/0x30
        generic_perform_write+0xca/0x1a0
        __generic_file_write_iter+0x190/0x1f0
        ext4_file_write_iter+0xe9/0x460
        __vfs_write+0xaa/0xe0
        vfs_write+0xa6/0x1a0
        SyS_write+0x46/0xa0
        entry_SYSCALL_64_fastpath+0x12/0x6a
        0xffffffffffffffff

      (Note, this does *NOT* happen in practice today because
       the kmap_atomic() does a pagefault_disable().  The trace
       above was obtained by taking out the pagefault_disable().)

      You can trigger the deadlock with this little code snippet:

        fd = open("foo", O_RDWR);
        fdmap = mmap(NULL, len, PROT_WRITE|PROT_READ, MAP_SHARED, fd, 0);
        write(fd, &fdmap[0], 1);

      mm: /proc/pid/smaps:: show proportional swap share of the mapping

      We want to know per-process workingset size for smart memory management
      on userland and we use swap(ex, zram) heavily to maximize memory
      efficiency so workingset includes swap as well as RSS.

      On such system, if there are lots of shared anonymous pages, it's really
      hard to figure out exactly how many each process consumes memory(ie, rss
      + wap) if the system has lots of shared anonymous memory(e.g, android).

      This patch introduces SwapPss field on /proc/<pid>/smaps so we can get
      more exact workingset size per process.

      Bongkyu tested it. Result is below.

      1. 50M used swap
      SwapTotal: 461976 kB
      SwapFree: 411192 kB

      $ adb shell cat /proc/*/smaps | grep "SwapPss:" | awk '{sum += $2} END 
{print sum}';

      $ adb shell cat /proc/*/smaps | grep "Swap:" | awk '{sum += $2} END 
{print sum}';

      pagemap: add mmap-exclusive bit for marking pages mapped only here

      This patch sets bit 56 in pagemap if this page is mapped only once.  It
      allows to detect exclusively used pages without exposing PFN:

      present file exclusive state
      0       0    0         non-present
      1       1    0         file page mapped somewhere else
      1       1    1         file page mapped only here
      1       0    0         anon non-CoWed page (shared with parent/child)
      1       0    1         anon CoWed page (or never forked)

      CoWed pages in (MAP_FILE | MAP_PRIVATE) areas are anon in this context.

      MMap-exclusive bit doesn't reflect potential page-sharing via swapcache:
      page could be mapped once but has several swap-ptes which point to it.
      Application could detect that by swap bit in pagemap entry and touch that
      pte via /proc/pid/mem to get real information.

      pagemap: check permissions and capabilities at open time

      This patchset makes pagemap useable again in the safe way (after row
      hammer bug it was made CAP_SYS_ADMIN-only).  This patchset restores access
      for non-privileged users but hides PFNs from them.

      Also it adds bit 'map-exclusive' which is set if page is mapped only here:
      it helps in estimation of working set without exposing pfns and allows to
      distinguish CoWed and non-CoWed private anonymous pages.

      Second patch removes page-shift bits and completes migration to the new
      pagemap format: flags soft-dirty and mmap-exclusive are available only in
      the new format.

      This patch (of 5):

      This patch moves permission checks from pagemap_read() into 
pagemap_open().

      Pointer to mm is saved in file->private_data. This reference pins only
      mm_struct itself. /proc/*/mem, maps, smaps already work in the same way.

      and ensure that other processes mapping this huge page have their page

      dax: fix race between simultaneous faults

      If two threads write-fault on the same hole at the same time, the winner
      of the race will return to userspace and complete their store, only to
      have the loser overwrite their store with zeroes.  Fix this for now by
      taking the i_mmap_sem for write instead of read, and do so outside the
      call to get_block().  Now the loser of the race will see the block has
      already been zeroed, and will not zero it again.

      This severely limits our scalability.  I have ideas for improving it, but
      those can wait for a later patch.

      ext4: start transaction before calling into DAX

      Jan Kara pointed out that in the case where we are writing to a hole, we
      can end up with a lock inversion between the page lock and the journal
      lock.  We can avoid this by starting the transaction in ext4 before
      calling into DAX.  The journal lock nests inside the superblock
      pagefault lock, so we have to duplicate that code from dax_fault, like
      XFS does.

      ext4: add ext4_get_block_dax()

      DAX wants different semantics from any currently-existing ext4 get_block
      callback.  Unlike ext4_get_block_write(), it needs to honour the
      'create' flag, and unlike ext4_get_block(), it needs to be able to
      return unwritten extents.  So introduce a new ext4_get_block_dax() which
      has those semantics.

      We could also change ext4_get_block_write() to honour the 'create' flag,
      but that might have consequences on other users that I do not currently
      understand.

      thp: change insert_pfn's return type to void

      It would make more sense to have all the return values from

      the convention into insert_pfn().  Suggested by Jeff Moyer.

      ext4: use ext4_get_block_write() for DAX

      DAX relies on the get_block function either zeroing newly allocated
      blocks before they're findable by subsequent calls to get_block, or
      marking newly allocated blocks as unwritten.  ext4_get_block() cannot
      create unwritten extents, but ext4_get_block_write() can.

      In order to handle the !CONFIG_TRANSPARENT_HUGEPAGES case, we need to
      return VM_FAULT_FALLBACK from the inlined dax_pmd_fault(), which is
      defined in linux/mm.h.  Given that we don't want to include <linux/mm.h>
      in <linux/fs.h>, the easiest solution is to move the DAX-related
      functions to a new header, <linux/dax.h>.  We could also have moved
      VM_FAULT_* definitions to a new header, or a different header that isn't
      quite such a boil-the-ocean header as <linux/mm.h>, but this felt like
      the best option.

      thp: vma_adjust_trans_huge(): adjust file-backed VMA too

      This series of patches adds support for using PMD page table entries to
      map DAX files.  We expect NV-DIMMs to start showing up that are many
      gigabytes in size and the memory consumption of 4kB PTEs will be
      astronomical.

      The patch series leverages much of the Transparant Huge Pages
      infrastructure, going so far as to borrow one of Kirill's patches from
      his THP page cache series.

      This patch (of 10):

      Since we're going to have huge pages in page cache, we need to call adjust
      file-backed VMA, which potentially can contain huge pages.

      For now we call it for all VMAs.

      Probably later we will need to introduce a flag to indicate that the VMA
      has huge pages.

      fails without this patch. Before the previous commit it gets the wrong
      page, now it segfaults (which is imho better).

      This is because copy_vma() wrongly assumes that if vma->vm_file == NULL
      is irrelevant until the first fault which will use do_anonymous_page().
      This is obviously wrong for the special mapping.

                printf("vdso pages differ: %d\n",
                        !!memcmp(vdso, vdso + PAGE_SIZE, PAGE_SIZE));

                // split into 2 vma's
                assert(mprotect(vdso, PAGE_SIZE, PROT_READ) == 0);

                // force another fault on the next check
                assert(madvise(vdso, 2 * PAGE_SIZE, MADV_DONTNEED) == 0);

                // now they no longer differ, the 2nd vm_pgoff is wrong
                printf("vdso pages differ: %d\n",
                        !!memcmp(vdso, vdso + PAGE_SIZE, PAGE_SIZE));

                return 0;
        }

      Output:

        vdso pages differ: 1
        vdso pages differ: 0

      This is because split_vma() correctly updates ->vm_pgoff, but the logic
      in insert_vm_struct() and special_mapping_fault() is absolutely broken,
      so the fault at vdso + PAGE_SIZE return the 1st page. The same happens
      if you simply unmap the 1st page.

      special_mapping_fault() does:

        pgoff = vmf->pgoff - vma->vm_pgoff;

      and this is _only_ correct if vma->vm_start mmaps the first page from
      ->vm_private_data array.

      vdso or any other user of install_special_mapping() is not anonymous,
      it has the "backing storage" even if it is just the array of pages.
      So we actually need to make vm_pgoff work as an offset in this array.

      Note: this also allows to fix another problem: currently gdb can't access
      "[vvar]" memory because in this case special_mapping_fault() doesn't work.
      Now that we can use ->vm_pgoff we can implement ->access() and fix this.

      mm: introduce vma_is_anonymous(vma) helper

      special_mapping_fault() is absolutely broken.  It seems it was always
      wrong, but this didn't matter until vdso/vvar started to use more than
      one page.

      And after this change vma_is_anonymous() becomes really trivial, it
      simply checks vm_ops == NULL.  However, I do think the helper makes
      sense.  There are a lot of ->vm_ops != NULL checks, the helper makes the
      caller's code more understandable (self-documented) and this is more
      grep-friendly.

      This patch (of 3):

      Preparation.  Add the new simple helper, vma_is_anonymous(vma), and change
      handle_pte_fault() to use it.  It will have more users.

      The name is not accurate, say a hpet_mmap()'ed vma is not anonymous.
      Perhaps it should be named vma_has_fault() instead.  But it matches the
      logic in mmap.c/memory.c (see next changes).  "True" just means that a
      page fault will use do_anonymous_page().

      selftests/userfaultfd: fix compiler warnings on 32-bit

      On 32-bit:

      Merge tag 'libnvdimm-for-4.3' of 
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

      Pull libnvdimm updates from Dan Williams:
       "This update has successfully completed a 0day-kbuild run and has
        appeared in a linux-next release.  The changes outside of the typical
        drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the
        removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and
        the introduction of ZONE_DEVICE + devm_memremap_pages().

        Summary:

         - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
           mechanism for adding device-driver-discovered memory regions to the
           kernel's direct map.

           This facility is used by the pmem driver to enable pfn_to_page()
           operations on the page frames returned by DAX ('direct_access' in
           'struct block_device_operations').

           For now, the 'memmap' allocation for these "device" pages comes
           from "System RAM".  Support for allocating the memmap from device
           memory will arrive in a later kernel.

         - Introduce memremap() to replace usages of ioremap_cache() and
           ioremap_wt().  memremap() drops the __iomem annotation for these
           mappings to memory that do not have i/o side effects.  The
           replacement of ioremap_cache() with memremap() is limited to the
           pmem driver to ease merging the api change in v4.3.

           Completion of the conversion is targeted for v4.4.

         - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
           driver, update the VFS DAX implementation and PMEM api to provide
           persistence guarantees for kernel operations on a DAX mapping.

         - Convert the ACPI NFIT 'BLK' driver to map the block apertures as
           cacheable to improve performance.

         - Miscellaneous updates and fixes to libnvdimm including support for
           issuing "address range scrub" commands, clarifying the optimal
           'sector size' of pmem devices, a clarification of the usage of the
           ACPI '_STA' (status) property for DIMM devices, and other minor
           fixes"

      device property: Don't overwrite addr when failing in 
device_get_mac_address

      The function device_get_mac_address is trying different property names
      in order to get the mac address. To check the return value, the variable
      addr (which contain the buffer pass by the caller) will be re-used. This
      means that if the previous property is not found, the next property will
      be read using a NULL buffer.

      Therefore it's only possible to retrieve the mac if node contains a
      property "mac-address". Fix it by using a temporary buffer for the
      return value.

      This has been introduced by commit 
4c96b7dc0d393f12c17e0d81db15aa4a820a6ab3

      usbnet: Fix a race between usbnet_stop() and the BH

      The race may happen when a device (e.g. YOTA 4G LTE Modem) is
      unplugged while the system is downloading a large file from the Net.

      Hardware breakpoints and Kprobes with delays were used to confirm that
      the race does actually happen.

      The race is on skb_queue ('next' pointer) between usbnet_stop()
      and rx_complete(), which, in turn, calls usbnet_bh().

      Here is a part of the call stack with the code where the changes to the
      queue happen. The line numbers are for the kernel 4.1.0:

      *0 __skb_unlink (skbuff.h:1517)
          prev->next = next;
      *1 defer_bh (usbnet.c:430)
          spin_lock_irqsave(&list->lock, flags);
          old_state = entry->state;
          entry->state = state;
          __skb_unlink(skb, list);
          spin_unlock(&list->lock);
          spin_lock(&dev->done.lock);
          __skb_queue_tail(&dev->done, skb);
          if (dev->done.qlen == 1)
              tasklet_schedule(&dev->bh);
          spin_unlock_irqrestore(&dev->done.lock, flags);
      *2 rx_complete (usbnet.c:640)
          state = defer_bh(dev, skb, &dev->rxq, state);

      At the same time, the following code repeatedly checks if the queue is
      empty and reads these values concurrently with the above changes:

      *0  usbnet_terminate_urbs (usbnet.c:765)
          /* maybe wait for deletions to finish. */
          while (!skb_queue_empty(&dev->rxq)
              && !skb_queue_empty(&dev->txq)
              && !skb_queue_empty(&dev->done)) {
                  schedule_timeout(msecs_to_jiffies(UNLINK_TIMEOUT_MS));
                  set_current_state(TASK_UNINTERRUPTIBLE);
                  netif_dbg(dev, ifdown, dev->net,
                        "waited for %d urb completions\n", temp);
          }
      *1  usbnet_stop (usbnet.c:806)
          if (!(info->flags & FLAG_AVOID_UNLINK_URBS))
              usbnet_terminate_urbs(dev);

      As a result, it is possible, for example, that the skb is removed from
      dev->rxq by __skb_unlink() before the check
      "!skb_queue_empty(&dev->rxq)" in usbnet_terminate_urbs() is made. It is
      also possible in this case that the skb is added to dev->done queue
      after "!skb_queue_empty(&dev->done)" is checked. So
      usbnet_terminate_urbs() may stop waiting and return while dev->done
      queue still has an item.

      Locking in defer_bh() and usbnet_terminate_urbs() was revisited to avoid
      this race.

      rbd: fix double free on rbd_dev->header_name

      If rbd_dev_image_probe() in rbd_dev_probe_parent() fails, header_name
      is freed twice: once in rbd_dev_probe_parent() and then in its caller
      rbd_dev_image_probe() (rbd_dev_image_probe() is called recursively to
      handle parent images).

      rbd_dev_probe_parent() is responsible for probing the parent, so it
      shouldn't muck with clone's fields.

      ceph: fix queuing inode to mdsdir's snaprealm

      During MDS failovers, MClientSnap message may cause kclient to move
      some inodes from root directory's snaprealm to mdsdir's snaprealm
      and queue snapshots for these inodes. For a FS has never created any
      snapshot, both root directory's snaprealm and mdsdir's snaprealm
      share the same snapshot contexts (both are ceph_empty_snapc). This
      confuses ceph_put_wrbuffer_cap_refs(), make it unable to distinguish
      snapshot buffers from head buffers.

      The fix is do not use ceph_empty_snapc as snaprealm's cached context.

      xen: Use correctly the Xen memory terminologies

      Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN
      is meant, I suspect this is because the first support for Xen was for
      PV. This resulted in some misimplementation of helpers on ARM and
      confused developers about the expected behavior.

      For instance, with pfn_to_mfn, we expect to get an MFN based on the name.
      Although, if we look at the implementation on x86, it's returning a GFN.

      For clarity and avoid new confusion, replace any reference to mfn with
      gfn in any helpers used by PV drivers. The x86 code will still keep some
      reference of pfn_to_mfn which may be used by all kind of guests
      No changes as been made in the hypercall field, even
      though they may be invalid, in order to keep the same as the defintion
      in xen repo.

      Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a
      name to close to the KVM function gfn_to_page.

      Take also the opportunity to simplify simple construction such
      as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean 
up
      will come in follow-up patches.

      arm/xen: implement correctly pfn_to_mfn

      After the commit introducing convertion between DMA and guest addresses,
      all the callers of pfn_to_mfn are expecting to get a GFN (Guest Frame
      Number). On ARM, all the guests are auto-translated so the GFN is equal
      to the Linux PFN (Pseudo-physical Frame Number).

      The current implementation may return an MFN if the caller is passing a
      PFN associated to a mapped foreign grant. In pratice, I haven't seen
      the problem on running guest but we should fix it for the sake of
      correctness.

      Correct the implementation by always returning the pfn passed in 
parameter.

      A follow-up patch will take care to rename pfn_to_mfn to a suitable
      name.

      xen: Make clear that swiotlb and biomerge are dealing with DMA address

      The swiotlb is required when programming a DMA address on ARM when a
      device is not protected by an IOMMU.

      In this case, the DMA address should always be equal to the machine 
address.
      For DOM0 memory, Xen ensure it by have an identity mapping between the
      guest address and host address. However, when mapping a foreign grant
      reference, the 1:1 model doesn't work.

      For ARM guest, most of the callers of pfn_to_mfn expects to get a GFN
      (Guest Frame Number), i.e a PFN (Page Frame Number) from the Linux point
      of view given that all ARM guest are auto-translated.

      Even though the name pfn_to_mfn is misleading, we need to ensure that
      those caller get a GFN and not by mistake a MFN. In pratical, I haven't
      seen error related to this but we should fix it for the sake of
      correctness.

      In order to fix the implementation of pfn_to_mfn on ARM in a follow-up
      patch, we have to introduce new helpers to return the DMA from a PFN and
      the invert.

      On x86, the new helpers will be an alias of pfn_to_mfn and mfn_to_pfn.

      The helpers will be used in swiotlb and xen_biovec_phys_mergeable.

      This is necessary in the latter because we have to ensure that the
      biovec code will not try to merge a biovec using foreign page and
      another using Linux memory.

      Lastly, the helper mfn_to_local_pfn has been renamed to bfn_to_local_pfn
      given that the only usage was in swiotlb.

      xen: limit memory to architectural maximum

      When a pv-domain (including dom0) is started it tries to size it's
      p2m list according to the maximum possible memory amount it ever can
      achieve. Limit the initial maximum memory size to the architectural
      limit of the hardware in order to avoid overflows during remapping
      of memory.

      This problem will occur when dom0 is started with an initial memory
      size being a multiple of 1GB, but without specifying it's maximum
      memory size. The kernel must be configured without
      CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen.

      xen: avoid another early crash of memory limited dom0

      Commit b1c9f169047b ("xen: split counting of extra memory pages...")
      introduced an error when dom0 was started with limited memory occurring
      only on some hardware.

      The problem arises in case dom0 is started with initial memory and
      maximum memory being the same. The kernel must be configured without
      CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen. If all
      of this is true and the E820 map of the machine is sparse (some areas
      are not covered) then the machine might crash early in the boot
      process.

      An example E820 map triggering the problem looks like this:

      In this case the area a0000-dffff isn't present in the map. This will
      confuse the memory setup of the domain when remapping the memory from
      such holes to populated areas.

      To avoid the problem the accounting of to be remapped memory has to
      count such holes in the E820 map as well.

      serial port and the irq handler for the serial port. During this phase 
spurious
      interrupts for the serial port may happen which then crashes the kernel 
because
      the action handler might not have been set up yet.

      So, basically it's a race condition between the serial port hardware and 
the
      CPU which sets up the necessary fields in the irq sructs. The main reason 
for
      this race is, that we unmask the serial port irqs too early without 
having set
      up everything properly before (which isn't easily possible because we 
need the
      IRQ number to register the serial ports).

      This patch is a work-around for this problem. It adds checks to the CPU 
irq
      handler to verify if the IRQ action field has been initialized already. 
If not,
      we just skip this interrupt (which isn't critical for a serial port at 
bootup).
      The real fix would probably involve rewriting all PA-RISC specific IRQ 
code
      (for CPU, IOSAPIC, GSC and EISA) to use IRQ domains with proper parenting 
of
      the irq chips and proper irq enabling along this line.

      This bug has been in the PA-RISC port since the beginning, but the crashes
      happened very rarely with currently used hardware.  But on the latest 
machine
      which I bought (a C8000 workstation), which uses the fastest CPUs (4 x 
PA8900,
      1GHz) and which has the largest possible L1 cache size (64MB each), the 
kernel
      crashed at every boot because of this race. So, without this patch the 
machine
      would currently be unuseable.

      For the record, here is the flow logic:
      1. serial_init_chip() in 8250_gsc.c calls iosapic_serial_irq().
      2. iosapic_serial_irq() calls txn_alloc_irq() to find the irq.
      3. iosapic_serial_irq() calls cpu_claim_irq() to register the CPU irq
      4. cpu_claim_irq() unmasks the CPU irq (which it shouldn't!)
      5. serial_init_chip() then registers the 8250 port.
      Problems:
      - In step 4 the CPU irq shouldn't have been registered yet, but after 
step 5
      - If serial irq happens between 4 and 5 have finished, the kernel will 
crash

      PCI,parisc: Enable 64-bit bus addresses on PA-RISC

      Commit 3a9ad0b ("PCI: Add pci_bus_addr_t") unconditionally introduced 
usage of
      64-bit PCI bus addresses on all 64-bit platforms which broke PA-RISC.

      It turned out that due to enabling the 64-bit addresses, the PCI logic 
decided
      to use the GMMIO instead of the LMMIO region. This commit simply disables
      registering the GMMIO and thus we fall back to use the LMMIO region as 
before.

      Reverts commit 45ea2a5fed6dacb9bb0558d8b21eacc1c45d5bb4

      virtio_balloon: do not change memory amount visible via /proc/meminfo

      Balloon device is frequently used as a mean of cooperative memory control
      in between guest and host to manage memory overcommitment. This is the
      typical case for any hosting workload when KVM guest is provided for
      end-user.

      Though there is a problem in this setup. The end-user and hosting provider
      have signed SLA agreement in which some amount of memory is guaranted for
      the guest. The good thing is that this memory will be given to the guest
      when the guest will really need it (f.e. with OOM in guest and with
      VIRTIO_BALLOON_F_DEFLATE_ON_OOM configuration flag set). The bad thing
      is that end-user does not know this.

      Balloon by default reduce the amount of memory exposed to the end-user
      each time when the page is stolen from guest or returned back by using
      adjust_managed_page_count and thus /proc/meminfo shows reduced amount
      of memory.

      Fortunately the solution is simple, we should just avoid to call
      adjust_managed_page_count with VIRTIO_BALLOON_F_DEFLATE_ON_OOM set.

      During CPU hotplug, if configure-connector fails for any reason,

      Btrfs: don't initialize a space info as full to prevent ENOSPC

      Commit 2e6e518335f8 ("Btrfs: fix block group ->space_info null pointer
      dereference") accidently marked a space info as full when initializing
      it with a value of 0 total bytes. This introduces an ENOSPC problem when
      writing file data if we mount a filesystem that has no data block groups
      allocated, because the data space info is initialized with 0 total bytes,
      marked as full, and it never gets its total bytes incremented by a
      (positive) value to unmark it as full (because there are no data block
      groups loaded when the fs is mounted).
      For metadata and system spaces this issue can never happen since we always
      have at least one metadata block group and one system block group (even
      for an empty filesystem).

      So fix this by just not initializing a space info as full, reverting the
      offending part of the commit mentioned above.

      The following test case for fstests reproduces the issue:

        Deatils:

         - large rework of EFI/EFD lifecycle handling to fix log recovery
           corruption issues, crashes and unmount hangs

         - separate metadata UUID on disk to enable changing boot label UUID
           for v5 filesystems

      NTB: Remove dma_sync_wait from ntb_async_rx

      The dma_sync_wait can hurt the performance of workloads mixed with both
      large and small frames.  Large frames will be copied using the dma
      engine.  Small frames will be copied by the cpu.  The dma_sync_wait
      prevents the cpu and dma engine copying in parallel.

      In the period where the cpu is copying, the dma engine is stopped.  The
      dma engine is not doing any useful work to copy large frames during that
      time, and the additional time to restart the dma engine for the next
      large frame.  This will decrease the throughput for the portion of a
      workload with large frames.

      In the period where the dma engine is copying, the cpu is held up
      waiting for dma to complete.  The small frames processing will be
      delayed until the dma is complete.  The RX frames are completed
      in-order, and the processing of small frames takes very little time, so
      dma_sync_wait may have an insignificant impact on the respose time of
      frames.  The more significant impact is to the system, because the delay
      in dma_sync_wait is implemented as busy non-blocking wait.  This can
      prevent the delayed core from doing any useful work, even if it could be
      processing work for other drivers, unrelated to transport RX processing.

      After applying the earlier patch to fix out-of-order RX acknoledgement,
      the dma_sync_wait is no longer necessary.  Remove it, so that cpu memcpy
      will proceed immediately for small frames, in parallel with ongoing dma
      for large frames.  Do not hold up the cpu from doing work while dma is
      in progress.  The prior fix will continue to ensure in-order completion
      of the RX frames to the upper layer, and in-order delivery of the RX
      acknoledgement.

      NTB: Add flow control to the ntb_netdev

      Right now if we push the NTB really hard, we start dropping packets due
      to not able to process the packets fast enough. We need to st:qop the
      upper layer from flooding us when that happens.

      A timer is necessary in order to restart the queue once the resource has
      been processed on the receive side. Due to the way NTB is setup, the
      resources on the tx side are tied to the processing of the rx side and
      there's no async way to know when the rx side has released those
      resources.

      NFSv4: Respect the server imposed limit on how many changes we may cache

      The NFSv4 delegation spec allows the server to tell a client to limit how
      much data it cache after the file is closed. In return, the server
      guarantees enough free space to avoid ENOSPC situations, etc.
      Prior to this patch, we assumed we could always cache aggressively after
      close. Unfortunately, this causes problems with servers that set the
      limit to 0 and therefore do not offer any ENOSPC guarantees.

      ARM: 8429/1: disable GCC SRA optimization

      While working on the 32-bit ARM port of UEFI, I noticed a strange
      corruption in the kernel log. The following snprintf() statement
      (in drivers/firmware/efi/efi.c:efi_md_typeattr_format())

        snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",

      was producing the following output in the log:

        |RUN|   |   |   |    |   |   |   |UC]

      As it turns out, this is caused by incorrect code being emitted for
      the string() function in lib/vsprintf.c. The following code

        if (!(spec.flags & LEFT)) {
                while (len < spec.field_width--) {
                        if (buf < end)
                                *buf = ' ';
                        ++buf;
                }
        }
        for (i = 0; i < len; ++i) {
                if (buf < end)
                        *buf = *s;
                ++buf; ++s;
        }
        while (len < spec.field_width--) {
                if (buf < end)
                        *buf = ' ';
                ++buf;
        }

      when called with len == 0, triggers an issue in the GCC SRA optimization
      pass (Scalar Replacement of Aggregates), which handles promotion of signed
      struct members incorrectly. This is a known but as yet unresolved issue.
      (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
      case, it is causing the second while loop to be executed erroneously a
      single time, causing the additional space characters to be printed.

      So disable the optimization by passing -fno-ipa-sra.

      powerpc/powernv/pci-ioda: fix kdump with non-power-of-2 crashkernel=

      The 32-bit TCE table initialization relies on the DMA window having a
      size equal to a power of 2 (and checks for it explicitly). But
      crashkernel= has no constraint that requires a power-of-2 be specified.
      This causes the kdump kernel to fail to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      and eventually the kdump kernel fails to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      The EINVAL response is because the DMA window (the 2GB base window) is
      larger than the kdump kernel's reserved memory (crashkernel=, in this
      case specified to be 1024M). The check in question,

       if ((window_size > memory_hotplug_max()) || !is_power_of_2(window_size))

      is a valid sanity check for pnv_pci_ioda2_table_alloc_pages(), so adjust
      the caller to pass in a smaller window size if our maximum memory value
      is smaller than the DMA window.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      The problem was seen on a Firestone machine originally.

      ALSA: usb-audio: Change internal PCM order

      New PCMs will now be added to the end of the chip's PCM list instead of 
to the
      front. This changes the way streams are combined so that the first capture
      stream will now be merged with the first playback stream instead of the 
last.

      This fixes a problem with ASUS U7. Cards with one playback stream and 
cards
      without capture streams should be unaffected by this change.

      Exception added for M-Audio Audiophile USB (tm) since it seems to have a

      scsi: fix scsi_error_handler vs. scsi_host_dev_release race

      b9d5c6b7ef57 ("[SCSI] cleanup setting task state in
      scsi_error_handler()") has introduced a race between scsi_error_handler
      and scsi_host_dev_release resulting in the hang when the device goes
      away because scsi_error_handler might miss a wake up:

      CPU0                                      CPU1
      scsi_error_handler                        scsi_host_dev_release
                                                  kthread_stop()
        kthread_should_stop()
          test_bit(KTHREAD_SHOULD_STOP)
                                            set_bit(KTHREAD_SHOULD_STOP)
                                            wake_up_process()

        set_current_state(TASK_INTERRUPTIBLE)
        schedule()

      The most straightforward solution seems to be to invert the ordering of
      the set_current_state and kthread_should_stop.

      The issue has been noticed during reboot test on a 3.0 based kernel but
      the current code seems to be affected in the same way.

      fcoe: Convert use of __constant_htons to htons

      In little endian cases, the macro htons unfolds to __swab16 which
      provides special case for constants. In big endian cases,
      __constant_htons and htons expand directly to the same expression.
      So, replace __constant_htons with htons with the goal of getting
      rid of the definition of __constant_htons completely.

      The semantic patch that performs this transformation is as follows:

      @@expression x;@@

      - __constant_htons(x)
      + htons(x)

      mpt2sas: setpci reset kernel oops fix

      cli ioctl access resulted in kernel oops

      1. pci_access_mutex lock added to provide synchronization between IOCTL,
         sysfs, PCI resource handling path

      2. gioc_lock spinlock to protect list operations over multiple
      controllers

      Date: Tue, 18 Aug 2015 11:58:13 +0530
      Subject: [PATCH] mpt2sas setpci reset oops fix

      In mpt2sas driver due to lack of synchronization between ioctl,
      BRM status access through sysfs, pci resource removal kernel oops
      happen as ioctl path and BRM status sysfs access path still tries
      to access the removed resources

      Two locks added to provide syncrhonization

      1. pci_access_mutex: Mutex to synchronize ioctl,sysfs show path and
      pci resource handling. PCI resource freeing will lead to free
      vital hardware/memory resource, which might be in use by cli/sysfs
      path functions resulting in Null pointer reference followed by kernel
      crash. To avoid the above race condition we use mutex syncrhonization
      which ensures the syncrhonization between cli/sysfs_show path

      Note: pci_access_mutex is used only if nytro warpdrive cards
      (ioc->is_warpdrive based on device id) are used
      as we could not test this case with other SAS2 HBA cards
      We can remove this check if this behaviour confirmed from other
      cards.

      2. spinlock on list operations over IOCs

      Case: when multiple warpdrive cards(IOCs) are in use
      Each IOC will added to the ioc list stucture on initialization.
      Watchdog threads run at regular intervals to check IOC for any
      fault conditions which will trigger the dead_ioc thread to
      deallocate pci resource, resulting deleting the IOC netry from list,
      this deletion need to protected by spinlock to enusre that
      ioc removal is syncrhonized, if not synchronized it might lead to
      list_del corruption as the ioc list is traversed in cli path

      scsi_debug: fix REPORT LUNS Well Known LU

      The use case to report 'REPORT LUNS WLUN' described
      in scsi_debug documentation didn't work because:
      scsi_scan_host_selected() checks for:
         lun < shost->max_lun

      To fix this we set:
        max_lun = SCSI_W_LUN_REPORT_LUNS + 1;

      mpt2sas: Refcount fw_events and fix unsafe list usage

      The fw_event_work struct is concurrently referenced at shutdown, so
      add a refcount to protect it, and refactor the code to use it.

      Additionally, refactor _scsih_fw_event_cleanup_queue() such that it
      no longer iterates over the list without holding the lock, since
      _firmware_event_work() concurrently deletes items from the list.

      mpt2sas: Refcount sas_device objects and fix unsafe list usage

      These objects can be referenced concurrently throughout the driver, we
      need a way to make sure threads can't delete them out from under each
      other. This patch adds the refcount, and refactors the code to use it.

      Additionally, we cannot iterate over the sas_device_list without
      holding the lock, or we risk corrupting random memory if items are
      added or deleted as we iterate. This patch refactors _scsih_probe_sas()
      to use the sas_device_list in a safe way.

      KVM: dynamic halt-polling

      There is a downside of always-poll since poll is still happened for idle
      vCPUs which can waste cpu usage. This patchset add the ability to adjust
      halt_poll_ns dynamically, to grow halt_poll_ns when shot halt is detected,
      and to shrink halt_poll_ns when long halt is detected.

      There are two new kernel parameters for changing the halt_poll_ns:
      halt_poll_ns_grow and halt_poll_ns_shrink.

                              no-poll      always-poll    dynamic-poll
      -----------------------------------------------------------------------
      Idle (nohz) vCPU %c0     0.15%        0.3%            0.2%
      Idle (250HZ) vCPU %c0    1.1%         4.6%~14%        1.2%
      TCP_RR latency           34us         27us            26.7us

      "Idle (X) vCPU %c0" is the percent of time the physical cpu spent in
      c0 over 60 seconds (each vCPU is pinned to a pCPU). (nohz) means the
      guest was tickless. (250HZ) means the guest was ticking at 250HZ.

      The big win is with ticking operating systems. Running the linux guest
      with nohz=off (and HZ=250), we save 3.4%~12.8% CPUs/second and get close
      to no-polling overhead levels by using the dynamic-poll. The savings
      should be even higher for higher frequency ticks.

      setting the value of linear, but not smart enough to realize the same
      X86EMU_CONTINUE blocks actual use of the value.  However, the value of

      upwards makes GCC happy with the code.

      KVM: x86: avoid uninitialized variable warning

      This does not show up on all compiler versions, so it sneaked into the
      first 4.3 pull request.  The fix is to mimic the logic of the "print
      sptes" loop in the "fill array" loop.  Then leaf and root can be
      both initialized unconditionally.

      Note that "leaf" now points to the first unused element of the array,
      not the last filled element.

      net: fec: normalize return value of pm_runtime_get_sync() in MDIO write

      If fec MDIO write method succeeds its return value comes from
      call to pm_runtime_get_sync().
      But pm_runtime_get_sync() can also return 1.

      In case of Micrel KSZ9031 PHY this value will then
      be returned along the call chain of phy_write() ->
      ksz9031_extended_write() -> ksz9031_center_flp_timing() ->
      ksz9031_config_init() -> phy_init_hw() -> phy_attach_direct() ->
      phy_connect_direct().

      Then phy_connect() will cast it into a pointer using ERR_PTR(),
      which then fec_enet_mii_probe() will try to dereference
      resulting in an oops.

      Fix it by normalizing return value of pm_runtime_get_sync()
      to be zero if positive in MDIO write method.

      be2net: Revert "make the RX_FILTER command asynchronous" commit

      The be_cmd_rx_filter() routine sends a non-embedded cmd to the FW and used
      a pre-allocated dma memory to hold the cmd payload. This worked fine when
      this cmd was synchronous. This cmd was changed to asynchronous mode by the
      commit 8af65c2f4("make the RX_FILTER command asynchronous"). So now when
      there are two quick invocations of this cmd, the 2nd request may end up
      overwriting the first request, causing FW cmd corruption.

      This patch reverts the offending commit and hence fixes the regression.

registers
         at 32 bits level.

      2) Restore previous default behaviour in bridge netfilter when 
CONFIG_IPV6=n,

      3) Out of bound access in ipset hash:net* set types, reported by Dave 
Jones'
         KASan utility, patch from Jozsef Kadlecsik.

      4) Fix ipset compilation with gcc 4.4.7 related to C99 initialization of
         unnamed unions, patch from Elad Raz.

      5) Add a workaround to address inconsistent endianess in the res_id field 
of
         nfnetlink batch messages, reported by Florian Westphal.

      6) Fix error paths of CT/synproxy since the conntrack template was moved 
to use
         kmalloc, patch from Daniel Borkmann.

      All of them look good to me to reach 4.2, I can route this to -stable 
myself

      net/ipv6: Correct PIM6 mrt_lock handling

      In the IPv6 multicast routing code the mrt_lock was not being released
      correctly in the MFC iterator, as a result adding or deleting a MIF would
      cause a hang because the mrt_lock could not be acquired.

      This fix is a copy of the code for the IPv4 case and ensures that the lock
      is released correctly.

      spi: Fix documentation of spi_alloc_master()

      Actually, spi_master_put() after spi_alloc_master() must _not_ be followed
      by kfree(). The memory is already freed with the call to spi_master_put()
      through spi_master_class, which registers a release function. Calling both
      spi_master_put() and kfree() results in often nasty (and delayed) crashes
      elsewhere in the kernel, often in the networking stack.

      This reverts commit eb4af0f5349235df2e4a5057a72fc8962d00308a.

      or
      http://lkml.iu.edu/hypermail/linux/kernel/1209.0/00790.html

      Alexey Klimov: This revert becomes valid after
      94c69f765f1b4a658d96905ec59928e3e3e07e6a when spi-imx.c
      has been fixed and there is no need to call kfree() so comment
      for spi_alloc_master() should be fixed.

      task_work: remove fifo ordering guarantee

      In commit f341861fb0b ("task_work: add a scheduling point in
      task_work_run()") I fixed a latency problem adding a cond_resched()
      call.

      Later, commit ac3d0da8f329 added yet another loop to reverse a list,
      bringing back the latency spike :

      I've seen in some cases this loop taking 275 ms, if for example a
      process with 2,000,000 files is killed.

      We could add yet another cond_resched() in the reverse loop, or we
      can simply remove the reversal, as I do not think anything
      would depend on order of task_work_add() submitted works.

      rtc: s5m: fix to update ctrl register

      According to datasheet, the S2MPS13X and S2MPS14X should update write
      buffer via setting WUDR bit to high after ctrl register is written.

      If not, ALARM interrupt of rtc-s5m doesn't happen first time when i use
      tools/testing/selftests/timers/rtctest.c test program and hour format is
      used to 12 hour mode in Odroid-XU3 board.

      One more issue is the RTC doesn't keep time on Odroid-XU3 board when i
      turn on board after power off even if RTC battery is connected. It can
      be solved as setting WUDR & RUDR bits to high at the same time after
      RTC_CTRL register is written. It's same with condition of only writing
      ALARM registers, so this is for only S2MPS14 and we should set WUDR &
      A_UDR bits to high on S2MPS13.

      I can't find any reasonable description about this like fix from
      datasheet, but can find similar codes from rtc driver source of
      hardkernel kernel and vendor kernel.

      ARM: config: Switch PXA27x platforms to use PXA RTC driver

      With the SA1100 and PXA RTC drivers be mutually exclusive and no
      longer sharing hardware, PXA27x/PXA3xx platforms must use the PXA RTC
      driver as the SA1100 platform device is no longer registered.

      This change should be almost transparent to userspace. Former users of
      pxa-rtc should be aware that 2 RTCs will be available on their kernels,
      rtc0 being sa1100-rtc and rtc1 being pxa-rtc. Any userspace relying on
      the fact that rtc0 was pxa-rtc should be fixed.

      As a consequence:
       - the first reboot after the switch will have the wrong time,
       - on dual boot platform where the other OS programs some logic into the
         sa1100 rtc IP, a lack of fix in userspace, ie. a kernel changing
         sa1100-rtc thinking it is pxa-rtc could have dire consequence, such
         as wiping the other OS data partition.

      (Thanks to Robert Jarmik for help on the above commit text.)

      rtc: sa1100/pxa: convert to run-time register mapping

      SA1100 and PXA differ only in register offsets which are currently
      hardcoded in a machine specific header. Some arm64 platforms (PXA1928)
      have this RTC block as well (and not the PXA270 variant).

      Convert the driver to use ioremap and set the register offsets 
dynamically.
      Since we are touching all the register accesses, convert them all to
      readl_relaxed/writel_relaxed.

      ARM: pxa: add memory resource to SA1100 RTC device

      The drivers for the SA1100 and PXA RTCs are now mutually exclusive, so
      add the memory resource for the sa1100-rtc device. Since the memory
      resource is already present in the pxa_rtc_resources, that makes
      sa1100_rtc_resources and pxa_rtc_resources equivalent, so use
      pxa_rtc_resources for both devices and remove the duplicate
      sa1100_rtc_resources.

      rtc: pxa: convert to use shared sa1100 functions

      Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a
      superset of functionality. Having 2 drivers sharing the same memory
      resource is not allowed by the driver model if resources are properly
      declared. This problem was avoided by not adding memory resources to the
      SA1100 RTC driver, but that prevents clean-up of the SA1100 driver.

      This commit converts the PXA RTC to use the exported SA1100 RTC
      functions. Now the sa1100-rtc and pxa-rtc devices are mutually
      exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

      The clock enable/disable codes for alarm have been removed from
      commit 24e1455493da ("drivers/rtc/rtc-s3c.c: delete duplicate clock
      control") and the clocks are disabled even if alarm is set, so alarm
      interrupt can't happen.

      The s3c_rtc_setaie function can be called several times with 'enabled'

      rtc: armada38x: Align RTC set time procedure with the official errata

      According to the Armada38x functional errata FE-3124064, writing to
      the RTC TIME register may fail. As a workaround, after writing to RTC
      TIME register, issue a dummy write of 0x0 twice to the RTC Status
      register.  This is the updated implementation of the Errata that
      eliminates the need of the long 100ms delay during the RTC set time
      procedure.

      The change removes redundant sysfs binary file boundary checks, since
      this task is already done on caller side in fs/sysfs/file.c

      The change enables burst mode of access to SRAM for any read()/write()
      operations, it is worth to mention that this may influence on
      userspace, for instance prior to the change

        read(fd, buf, 1);
        read(fd, buf + 1, 1);

      and

        read(fd, buf, 2);

      sequences of syscalls over DS1511's sysfs "nvram" fd led to different
      DS1511 state changes and/or buf content, if some userspace applications
      are written specifically for DS1511 and exploit this strange
      "feature", they may be impacted.

      Also the change corrects NVRAM size accessible to userspace from 255
      bytes to 256 bytes.

      For information, the year field of the rtc_time structure contains the
      value to add to 1970 to obtain the current year.

      This was a hack to be able to support years for 1970 to 2069.

      rtc: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

  Author: Adrian Huang <adrianhuang0701@xxxxxxxxx>
  Date:   Mon Jul 6 12:19:12 2015 +0800

      rtc: cmos: Cancel alarm timer if alarm time is equal to now+1 seconds

      Steps to reproduce the problem:
        1) Enable RTC wake-up option in BIOS Setup
        2) Issue one of these commands in the OS: "poweroff"
           or "shutdown -h now"
        3) System will shut down and then reboot automatically

      Root-cause of the issue:
        1) During the shutdown process, the hwclock utility is used
           to save the system clock to hardware clock (RTC).
        2) The hwclock utility invokes ioctl() with RTC_UIE_ON. The
           kernel configures the RTC alarm for the periodic interrupt
           (every 1 second).
        3) The hwclock uitlity closes the /dev/rtc0 device, and the
           kernel disables the RTC alarm irq (AIE bit of Register B)
           via ioctl() with RTC_UIE_OFF. But, the configured alarm
           time is the current_time + 1.
        4) After the next 1 second is elapsed, the AF (alarm
           interrupt flag) of Register C is set.
        5) The S5 handler in BIOS is invoked to configure alarm
           registers (enable AIE bit and configure alarm date/time).
           But, BIOS does not clear the previous interrupt status
           during alarm configuration. Therefore, "AF=AIE=1" causes
           the rtc device to trigger an interrupt.
        6) So, the machine reboots automatically right after shutdown.

      This patch cancels the alarm timer if the following condictions are
      met (suggested by Alexandre):
        1) The configured alarm time is equal to current_time + 1
           seconds.
        2) The AIE timer is not in use.

      The member 'alarm_expires' is introduced in struct cmos_rtc because
      of the following reasons:
        1) The configured alarm time can be retrieved from
           cmos_read_alarm(), but we need to take the 'wrapped
           timestamp' and 'time rollover' into consideration. The
           function __rtc_read_alarm() eliminates the concerns. To
           avoid the duplicated code in the lower level RTC driver,
           invoking __rtc_read_alarm from the lower level RTC driver
           is not encouraged. Moreover, the compilation error 'the
           undefined __rtc_read_alarm" is observed if the lower level
           RTC driver is compiled as a kernel module.
        2) The uie_rtctimer.node.expires and aie_timer.node.expires can
           be retrieved for the configured alarm time. But, the problem
           is that either of them might configure the CMOS alarm time.
           We cannot make sure UIE timer or AIE tiemr configured the
           CMOS alarm time before. (uie_rtctimer or aie_timer is enabled
           and then is disabled).
        3) The patch introduces the member 'alarm_expires' to keep the
           newly configured alarm time, so the above-mentioned concerns
           can be eliminated.

      The issue goes away after 20-time shutdown tests.

      rtc: da9063: Add DA9062 RTC capability to DA9063 RTC driver

      Add DA9062 RTC support into the existing DA9063 RTC driver component by
      using generic access tables for common register and bit mask definitions.

      The following change will add generic register and bit mask support to the
      DA9063 RTC. The changes are slightly complicated by requiring support for
      three register sets: DA9063-AD, DA9063-BB and DA9062-AA.

      The following alterations have been made to the DA9063 RTC:

      - Addition of a da9063_compatible_rtc_regmap structure to hold all generic
        registers and bitmasks for this type of RTC component.
      - A re-write of struct da9063 to use pointers for regmap and compatible
        registers/masks definitions
      - Addition of a of_device_id table for DA9063 and DA9062 defaults
      - Refactoring functions to use struct da9063_compatible_rtc accesses to
        generic registers/masks instead of using defines from registers.h
      - Re-work of da9063_rtc_probe() to use of_match_node() and 
dev_get_regmap()
        to provide initialisation of generic registers and masks and access to
        regmap

      rtc: opal: Enable alarms only when opal supports tpo

      rtc-opal driver provides support for rtc alarms via
      timed-power-on(tpo). However some Power platforms like BML use a fake
      rtc clock and don't support tpo. Such platforms are indicated by the
      missing 'has-tpo' property in the device tree.

      Current implementation however enables callback for
      rtc_class_ops.read/set alarm irrespective of the tpo support from the
      platform. This results in a failed opal call when kernel tries to read
      an existing alarms via opal_get_tpo_time during rtc device registration.

      This patch fixes this issue by setting opal_rtc_ops.read/set_alarm
      callback pointers only when tpo is supported.

      rtc: ds1307: Support optional wakeup interrupt source

      With the recent pinctrl-single changes, SoCs such as Texas
      Instrument's OMAP processors can treat wake-up events from deeper idle
      states as interrupts.

      Let's add support for the optional second interrupt for wake-up using
      the generic wakeirq support added in commit 4990d4fe327b ("PM /
      Wakeirq: Add automated device wake IRQ handling")

      Finally, to pass the wake-up interrupt in the dts file,
      interrupts-extended property needs to be passed.

      This is similar in approach to commit 2a0b965cfb6e ("serial: omap: Add
      support for optional wake-up") + ee83bd3b6483 ("serial: omap: Switch
      wake-up interrupt to generic wakeirq")

      x86/vm86: Block non-root vm86(old) if mmap_min_addr != 0

      vm86 exposes an interesting attack surface against the entry
      code. Since vm86 is mostly useless anyway if mmap_min_addr != 0,
      just turn it off in that case.

      There are some reports that vbetool can work despite setting
      mmap_min_addr to zero.  This shouldn't break that use case,
      as CAP_SYS_RAWIO already overrides mmap_min_addr.

      mm: make GUP handle pfn mapping unless FOLL_GET is requested

      With DAX, pfn mapping becoming more common.  The patch adjusts GUP code to
      cover pfn mapping for cases when we don't need struct page to proceed.

      To make it possible, let's change follow_page() code to return -EEXIST
      error code if proper page table entry exists, but no corresponding struct
      page.  __get_user_page() would ignore the error code and move to the next
      page frame.

      The immediate effect of the change is working MAP_POPULATE and mlock() on
      DAX mappings.

      mm: memcontrol: bring back the VM_BUG_ON() in mem_cgroup_swapout()

      Clark stumbled over a VM_BUG_ON() in -RT which was then was removed by
      Johannes in commit f371763a79d ("mm: memcontrol: fix false-positive
      VM_BUG_ON() on -rt").  The comment before that patch was a tiny bit better
      than it is now.  While the patch claimed to fix a false-postive on -RT
      this was not the case.  None of the -RT folks ACKed it and it was not a
      false positive report.  That was a *real* problem.

      This patch updates the comment that is improper because it refers to
      "disabled preemption" as a consequence of that lock being taken.  A
      spin_lock() disables preemption, true, but in this case the code relies on
      the fact that the lock _also_ disables interrupts once it is acquired.
      And this is the important detail (which was checked the VM_BUG_ON()) which
      needs to be pointed out.  This is the hint one needs while looking at the
      code.  It was explained by Johannes on the list that the per-CPU variables
      are protected by local_irq_save().  The BUG_ON() was helpful.  This code
      has been workarounded in -RT in the meantime.  I wouldn't mind running
      into more of those if the code in question uses *special* kind of locking
      since now there is no verification (in terms of lockdep or BUG_ON()) and
      therefore I bring the VM_BUG_ON() check back in.

      The two functions after the comment could also have a "local_irq_save()"
      dance around them in order to serialize access to the per-CPU variables.
      This has been avoided because the interrupts should be off.

      genalloc: add support of multiple gen_pools per device

      This change fills devm_gen_pool_create()/gen_pool_get() "name" argument
      stub with contents and extends of_gen_pool_get() functionality on this
      basis.

      If there is no associated platform device with a device node passed to
      of_gen_pool_get(), the function attempts to get a label property or device
      node name (= repeats MTD OF partition standard) and seeks for a named
      gen_pool registered by device of the parent device node.

      The main idea of the change is to allow registration of independent
      gen_pools under the same umbrella device, say "partitions" on "storage
      device", the original functionality of one "partition" per "storage
      device" is untouched.

      genalloc: add name arg to gen_pool_get() and devm_gen_pool_create()

      This change modifies gen_pool_get() and devm_gen_pool_create() client
      interfaces adding one more argument "name" of a gen_pool object.

      Due to implementation gen_pool_get() is capable to retrieve only one
      gen_pool associated with a device even if multiple gen_pools are created,
      fortunately right at the moment it is sufficient for the clients, hence
      provide NULL as a valid argument on both producer devm_gen_pool_create()
      and consumer gen_pool_get() sides.

      Because only one created gen_pool per device is addressable, explicitly
      add a restriction to devm_gen_pool_create() to create only one gen_pool
      per device, this implies two possible error codes returned by the
      function, account it on client side (only misc/sram).  This completes
      client side changes related to genalloc updates.

      mm: defer flush of writable TLB entries

      If a PTE is unmapped and it's dirty then it was writable recently.  Due to
      deferred TLB flushing, it's best to assume a writable TLB cache entry
      exists.  With that assumption, the TLB must be flushed before any IO can
      start or the page is freed to avoid lost writes or data corruption.  This
      patch defers flushing of potentially writable TLBs as long as possible.

      mm: send one IPI per CPU to TLB flush all entries after unmapping pages

      An IPI is sent to flush remote TLBs when a page is unmapped that was
      potentially accesssed by other CPUs.  There are many circumstances where
      this happens but the obvious one is kswapd reclaiming pages belonging to a
      running process as kswapd and the task are likely running on separate
      CPUs.

      On small machines, this is not a significant problem but as machine gets
      larger with more cores and more memory, the cost of these IPIs can be
      high.  This patch uses a simple structure that tracks CPUs that
      potentially have TLB entries for pages being unmapped.  When the unmapping
      is complete, the full TLB is flushed on the assumption that a refill cost
      is lower than flushing individual entries.

      Architectures wishing to do this must give the following guarantee.

              If a clean page is unmapped and not immediately flushed, the
              architecture must guarantee that a write to that linear address
              from a CPU with a cached TLB entry will trap a page fault.

      This is essentially what the kernel already depends on but the window is
      much larger with this patch applied and is worth highlighting.  The
      architecture should consider whether the cost of the full TLB flush is
      higher than sending an IPI to flush each individual entry.  An additional
      architecture helper called flush_tlb_local is required.  It's a trivial
      wrapper with some accounting in the x86 case.

      The impact of this patch depends on the workload as measuring any benefit
      requires both mapped pages co-located on the LRU and memory pressure.  The
      case with the biggest impact is multiple processes reading mapped pages
      taken from the vm-scalability test suite.  The test case uses NR_CPU
      readers of mapped files that consume 10*RAM.

      This is showing that the readers completed 24.40% faster with 29% less

      test and the patched kernel was interrupts 180K times per second.

      It's still a noticeable improvement with vmstat showing interrupts went
      from roughly 500K per second to 45K per second.

      The patch will have no impact on workloads with no memory pressure or have
      relatively few mapped pages.  It will have an unpredictable impact on the
      workload running on the CPU being flushed as it'll depend on how many TLB
      entries need to be refilled and how long that takes.  Worst case, the TLB
      will be completely cleared of active entries when the target PFNs were not
      resident at all.

      x86, mm: trace when an IPI is about to be sent

      When unmapping pages it is necessary to flush the TLB.  If that page was
      accessed by another CPU then an IPI is used to flush the remote CPU.  That
      is a lot of IPIs if kswapd is scanning and unmapping >100K pages per
      second.

      There already is a window between when a page is unmapped and when it is
      TLB flushed.  This series increases the window so multiple pages can be
      flushed using a single IPI.  This should be safe or the kernel is hosed
      already.

      Patch 1 simply made the rest of the series easier to write as ftrace
              could identify all the senders of TLB flush IPIS.

      Patch 2 tracks what CPUs potentially map a PFN and then sends an IPI
              to flush the entire TLB.

      Patch 3 tracks when there potentially are writable TLB entries that
              need to be batched differently

      Patch 4 increases SWAP_CLUSTER_MAX to further batch flushes

      The performance impact is documented in the changelogs but in the 
optimistic
      case on a 4-socket machine the full series reduces interrupts from 900K
      interrupts/second to 60K interrupts/second.

      This patch (of 4):

      It is easy to trace when an IPI is received to flush a TLB but harder to
      detect what event sent it.  This patch makes it easy to identify the
      source of IPIs being transmitted for TLB flushes on x86.

      userfaultfd: propagate the full address in THP faults

      The THP faults were not propagating the original fault address.  The
      latest version of the API with uffd.arg.pagefault.address is supposed to
      propagate the full address through THP faults.

      This was not a kernel crashing bug and it wouldn't risk to corrupt user
      memory, but it would cause a SIGBUS failure because the wrong page was
      being copied.

      For various reasons this wasn't easily reproducible in the qemu workload,
      but the strestest exposed the problem immediately.

      userfaultfd: allow signals to interrupt a userfault

      This is only simple to achieve if the userfault is going to return to
      userland (not to the kernel) because we can avoid returning VM_FAULT_RETRY
      despite we temporarily released the mmap_sem.  The fault would just be
      retried by userland then.  This is safe at least on x86 and powerpc (the
      two archs with the syscall implemented so far).

      Hint to verify for which archs this is safe: after handle_mm_fault
      returns, no access to data structures protected by the mmap_sem must be
      done by the fault code in arch/*/mm/fault.c until up_read(&mm->mmap_sem)
      is called.

      This has two main benefits: signals can run with lower latency in
      production (signals aren't blocked by userfaults and userfaults are
      immediately repeated after signal processing) and gdb can then trivially
      debug the threads blocked in this kind of userfaults coming directly from
      userland.

      On a side note: while gdb has a need to get signal processed, coredumps
      always worked perfectly with userfaults, no matter if the userfault is
      triggered by GUP a kernel copy_user or directly from userland.

      userfaultfd: require UFFDIO_API before other ioctls

      UFFDIO_API was already forced before read/poll could work.  This makes the
      code more strict to force it also for all other ioctls.

      All users would already have been required to call UFFDIO_API before
      invoking other ioctls but this makes it more explicit.

      This will ensure we can change all ioctls (all but UFFDIO_API/struct
      uffdio_api) with a bump of uffdio_api.api.

      There's no actual plan or need to change the API or the ioctl, the current
      API already should cover fine even the non cooperative usage, but this is
      just for the longer term future just in case.

      userfaultfd: avoid mmap_sem read recursion in mcopy_atomic

      If the rwsem starves writers it wasn't strictly a bug but lockdep
      doesn't like it and this avoids depending on lowlevel implementation
      details of the lock.

      userfaultfd: solve the race between UFFDIO_COPY|ZEROPAGE and read

      Solve in-kernel the race between UFFDIO_COPY|ZEROPAGE and
      userfaultfd_read if they are run on different threads simultaneously.

      Until now qemu solved the race in userland: the race was explicitly
      and intentionally left for userland to solve. However we can also
      solve it in kernel.

      Requiring all users to solve this race if they use two threads (one
      for the background transfer and one for the userfault reads) isn't
      very attractive from an API prospective, furthermore this allows to
      remove a whole bunch of mutex and bitmap code from qemu, making it
      faster. The cost of __get_user_pages_fast should be insignificant
      considering it scales perfectly and the pagetables are already hot in
      the CPU cache, compared to the overhead in userland to maintain those
      structures.

      Applying this patch is backwards compatible with respect to the
      userfaultfd userland API, however reverting this change wouldn't be
      backwards compatible anymore.

      Without this patch qemu in the background transfer thread, has to read
      the old state, and do UFFDIO_WAKE if old_state is missing but it
      become REQUESTED by the time it tries to set it to RECEIVED (signaling
      the other side received an userfault).

          vcpu                background_thr userfault_thr
          -----               -----          -----
          vcpu0 handle_mm_fault()

                              postcopy_place_page
                              read old_state -> MISSING
                              UFFDIO_COPY 0x7fb76a139000 (no wakeup, still 
pending)

          vcpu0 fault at 0x7fb76a139000 enters handle_userfault
          poll() is kicked

                                              poll() -> POLLIN
                                              read() -> 0x7fb76a139000
                                              
postcopy_pmi_change_state(MISSING, REQUESTED) -> REQUESTED

                              tmp_state = postcopy_pmi_change_state(old_state, 
RECEIVED) -> REQUESTED
                              /* check that no userfault raced with UFFDIO_COPY 
*/
                              if (old_state == MISSING && tmp_state == 
REQUESTED)
                                      UFFDIO_WAKE from background thread

      And a second case where a UFFDIO_WAKE would be needed is in the userfault 
thread:

          vcpu                background_thr userfault_thr
          -----               -----          -----
          vcpu0 handle_mm_fault()

                              postcopy_place_page
                              read old_state -> MISSING
                              UFFDIO_COPY 0x7fb76a139000 (no wakeup, still 
pending)
                              tmp_state = postcopy_pmi_change_state(old_state, 
RECEIVED) -> RECEIVED

          vcpu0 fault at 0x7fb76a139000 enters handle_userfault
          poll() is kicked

                                              poll() -> POLLIN
                                              read() -> 0x7fb76a139000

                                              if 
(postcopy_pmi_change_state(MISSING, REQUESTED) == RECEIVED)
                                                      UFFDIO_WAKE from 
userfault thread

      This patch removes the need of both UFFDIO_WAKE and of the associated
      per-page tristate as well.

      userfaultfd: wake pending userfaults

      This is an optimization but it's a userland visible one and it affects
      the API.

      The downside of this optimization is that if you call poll() and you
      get POLLIN, read(ufd) may still return -EAGAIN. The blocked userfault
      may be waken by a different thread, before read(ufd) comes
      around. This in short means that poll() isn't really usable if the
      userfaultfd is opened in blocking mode.

      userfaults won't wait in "pending" state to be read anymore and any
      UFFDIO_WAKE or similar operations that has the objective of waking
      userfaults after their resolution, will wake all blocked userfaults
      for the resolved range, including those that haven't been read() by
      userland yet.

      The behavior of poll() becomes not standard, but this obviates the
      need of "spurious" UFFDIO_WAKE and it lets the userland threads to
      restart immediately without requiring an UFFDIO_WAKE. This is even
      more significant in case of repeated faults on the same address from
      multiple threads.

      This optimization is justified by the measurement that the number of
      spurious UFFDIO_WAKE accounts for 5% and 10% of the total
      userfaults for heavy workloads, so it's worth optimizing those away.

      userfaultfd: change the read API to return a uffd_msg

      I had requests to return the full address (not the page aligned one) to
      userland.

      It's not entirely clear how the page offset could be relevant because
      userfaults aren't like SIGBUS that can sigjump to a different place and it
      actually skip resolving the fault depending on a page offset.  There's
      currently no real way to skip the fault especially because after a
      UFFDIO_COPY|ZEROPAGE, the fault is optimized to be retried within the
      kernel without having to return to userland first (not even self modifying
      code replacing the .text that touched the faulting address would prevent
      the fault to be repeated).  Userland cannot skip repeating the fault even
      more so if the fault was triggered by a KVM secondary page fault or any
      get_user_pages or any copy-user inside some syscall which will return to
      kernel code.  The second time FAULT_FLAG_RETRY_NOWAIT won't be set leading
      to a SIGBUS being raised because the userfault can't wait if it cannot
      release the mmap_map first (and FAULT_FLAG_RETRY_NOWAIT is required for
      that).

      Still returning userland a proper structure during the read() on the uffd,
      can allow to use the current UFFD_API for the future non-cooperative
      extensions too and it looks cleaner as well.  Once we get additional
      fields there's no point to return the fault address page aligned anymore
      to reuse the bits below PAGE_SHIFT.

      The only downside is that the read() syscall will read 32bytes instead of
      8bytes but that's not going to be measurable overhead.

      The total number of new events that can be extended or of new future bits
      for already shipped events, is limited to 64 by the features field of the
      uffdio_api structure.  If more will be needed a bump of UFFD_API will be
      required.

      userfaultfd: Rename uffd_api.bits into .features

      This is (seems to be) the minimal thing that is required to unblock
      standard uffd usage from the non-cooperative one.  Now more bits can be
      added to the features field indicating e.g.  UFFD_FEATURE_FORK and others
      needed for the latter use-case.

      userfaultfd: add new syscall to provide memory externalization

      Once an userfaultfd has been created and certain region of the process
      virtual address space have been registered into it, the thread responsible
      for doing the memory externalization can manage the page faults in
      userland by talking to the kernel using the userfaultfd protocol.

      poll() can be used to know when there are new pending userfaults to be
      read (POLLIN).

      userfaultfd: prevent khugepaged to merge if userfaultfd is armed

      If userfaultfd is armed on a certain vma we can't "fill" the holes with
      zeroes or we'll break the userland on demand paging.  The holes if the
      userfault is armed, are really missing information (not zeroes) that the
      userland has to load from network or elsewhere.

      The same issue happens for wrprotected ptes that we can't just convert
      into a single writable pmd_trans_huge.

      We could however in theory still merge across zeropages if only
      VM_UFFD_MISSING is set (so if VM_UFFD_WP is not set)...  that could be
      slightly improved but it'd be much more complex code for a tiny corner
      case.

      userfaultfd: call handle_userfault() for userfaultfd_missing() faults

      This is where the page faults must be modified to call
      handle_userfault() if userfaultfd_missing() is true (so if the
      vma->vm_flags had VM_UFFD_MISSING set).

      handle_userfault() then takes care of blocking the page fault and
      delivering it to userland.

      The fault flags must also be passed as parameter so the "read|write"
      kind of fault can be passed to userland.

      userfaultfd: linux/Documentation/vm/userfaultfd.txt

      This is the latest userfaultfd patchset.  The postcopy live migration
      feature on the qemu side is mostly ready to be merged and it entirely
      depends on the userfaultfd syscall to be merged as well.  So it'd be great
      if this patchset could be reviewed for merging in -mm.

      Userfaults allow to implement on demand paging from userland and more
      generally they allow userland to more efficiently take control of the
      behavior of page faults than what was available before (PROT_NONE +
      SIGSEGV trap).

      The use cases are:

      1) KVM postcopy live migration (one form of cloud memory
         externalization).

         KVM postcopy live migration is the primary driver of this work:

          
http://blog.zhaw.ch/icclab/setting-up-post-copy-live-migration-in-openstack/
          http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04873.html

      2) postcopy live migration of binaries inside linux containers:

          http://thread.gmane.org/gmane.linux.kernel.mm/132662

      3) KVM postcopy live snapshotting (allowing to limit/throttle the
         memory usage, unlike fork would, plus the avoidance of fork
         overhead in the first place).

         While the wrprotect tracking is not implemented yet, the syscall API is
         already contemplating the wrprotect fault tracking and it's generic 
enough
         to allow its later implementation in a backwards compatible fashion.

      4) KVM userfaults on shared memory. The UFFDIO_COPY lowlevel method
         should be extended to work also on tmpfs and then the
         uffdio_register.ioctls will notify userland that UFFDIO_COPY is
         available even when the registered virtual memory range is tmpfs
         backed.

      5) alternate mechanism to notify web browsers or apps on embedded
         devices that volatile pages have been reclaimed. This basically
         avoids the need to run a syscall before the app can access with the
         CPU the virtual regions marked volatile. This depends on point 4)
         to be fulfilled first, as volatile pages happily apply to tmpfs.

      Even though there wasn't a real use case requesting it yet, it also
      allows to implement distributed shared memory in a way that readonly
      shared mappings can exist simultaneously in different hosts and they
      can be become exclusive at the first wrprotect fault.

      This patch (of 22):

      Add documentation.

      mm/slub: don't wait for high-order page allocation

      Description is almost copied from commit fb05e7a89f50 ("net: don't wait
      for order-3 page allocation").

      I saw excessive direct memory reclaim/compaction triggered by slub.  This
      causes performance issues and add latency.  Slub uses high-order
      allocation to reduce internal fragmentation and management overhead.  But,
      direct memory reclaim/compaction has high overhead and the benefit of
      high-order allocation can't compensate the overhead of both work.

      This patch makes auxiliary high-order allocation atomic.  If there is no
      memory pressure and memory isn't fragmented, the alloction will still
      success, so we don't sacrifice high-order allocation's benefit here.  If
      the atomic allocation fails, direct memory reclaim/compaction will not be
      triggered, allocation fallback to low-order immediately, hence the direct
      memory reclaim/compaction overhead is avoided.  In the allocation failure
      case, kswapd is waken up and trying to make high-order freepages, so
      allocation could success next time.

      Following is the test to measure effect of this patch.

      System: QEMU, CPU 8, 512 MB
      Mem: 25% memory is allocated at random position to make fragmentation.
       Memory-hogger occupies 150 MB memory.

      mm/slub: fix slab double-free in case of duplicate sysfs filename

      sysfs_slab_add() shouldn't call kobject_put at error path: this puts last
      reference of kmem-cache kobject and frees it.  Kmem cache will be freed
      second time at error path in kmem_cache_create().

      For example this happens when slub debug was enabled in runtime and
      somebody creates new kmem cache:

      # echo 1 | tee /sys/kernel/slab/*/sanity_checks
      # modprobe configfs

      "configfs_dir_cache" cannot be merged because existing slab have debug and
      cannot create new slab because unique name ":t-0000096" already taken.

      mm/slub: move slab initialization into irq enabled region

      Initializing a new slab can introduce rather large latencies because most
      of the initialization runs always with interrupts disabled.

      There is no point in doing so.  The newly allocated slab is not visible
      yet, so there is no reason to protect it against concurrent alloc/free.

      Move the expensive parts of the initialization into allocate_slab(), so
      for all allocations with GFP_WAIT set, interrupts are enabled.

      slub: add support for kmem_cache_debug in bulk calls

      Per request of Joonsoo Kim adding kmem debug support.

      I've tested that when debugging is disabled, then there is almost no
      performance impact as this code basically gets removed by the compiler.

      Need some guidance in enabling and testing this.

      slub: initial bulk free implementation

      This implements SLUB specific kmem_cache_free_bulk().  SLUB allocator now
      both have bulk alloc and free implemented.

      Choose to reenable local IRQs while calling slowpath __slab_free().  In
      worst case, where all objects hit slowpath call, the performance should
      still be faster than fallback function __kmem_cache_free_bulk(), because
      local_irq_{disable+enable} is very fast (7-cycles), while the fallback
      invokes this_cpu_cmpxchg() which is slightly slower (9-cycles).
      Nitpicking, this should be faster for N>=4, due to the entry cost of
      local_irq_{disable+enable}.

      Do notice that the save+restore variant is very expensive, this is key to
      why this optimization works.

      slub: improve bulk alloc strategy

      Call slowpath __slab_alloc() from within the bulk loop, as the side-effect
      of this call likely repopulates c->freelist.

      Choose to reenable local IRQs while calling slowpath.

      Saving some optimizations for later.  E.g.  it is possible to extract
      parts of __slab_alloc() and avoid the unnecessary and expensive (37
      cycles) local_irq_{save,restore}.  For now, be happy calling
      __slab_alloc() this lower icache impact of this func and I don't have to
      worry about correctness.

      slub bulk alloc: extract objects from the per cpu slab

      First piece: acceleration of retrieval of per cpu objects

      If we are allocating lots of objects then it is advantageous to disable
      interrupts and avoid the this_cpu_cmpxchg() operation to get these objects
      faster.

      Note that we cannot do the fast operation if debugging is enabled, because
      we would have to add extra code to do all the debugging checks.  And it
      would not be fast anyway.

      Note also that the requirement of having interrupts disabled avoids having
      to do processor flag operations.

      Allocate as many objects as possible in the fast way and then fall back to
      the generic implementation for the rest of the objects.

      slab: infrastructure for bulk object allocation and freeing

      Add the basic infrastructure for alloc/free operations on pointer arrays.
      It includes a generic function in the common slab code that is used in
      this infrastructure patch to create the unoptimized functionality for slab
      bulk operations.

      Allocators can then provide optimized allocation functions for situations
      in which large numbers of objects are needed.  These optimization may
      avoid taking locks repeatedly and bypass metadata creation if all objects
      in slab pages can be used to provide the objects required.

      Allocators can extend the skeletons provided and add their own code to the
      bulk alloc and free functions.  They can keep the generic allocation and
      freeing and just fall back to those if optimizations would not work (like
      for example when debugging is on).

      slub: fix spelling succedd to succeed

      With this patchset the SLUB allocator now has both bulk alloc and free
      implemented.

      This patchset mostly optimizes the "fastpath" where objects are available
      on the per CPU fastpath page.  This mostly amortize the less-heavy
      none-locked cmpxchg_double used on fastpath.

      The "fallback" bulking (e.g __kmem_cache_free_bulk) provides a good basis
      for comparison.  Measurements[1] of the fallback functions
      __kmem_cache_{free,alloc}_bulk have been copied from slab_common.c and
      forced "noinline" to force a function call like slab_common.c.

      Benchmarking shows impressive improvements in the "fastpath" with a small
      number of objects in the working set.  Once the working set increases,
      resulting in activating the "slowpath" (that contains the heavier locked
      cmpxchg_double) the improvement decreases.

      I'm currently working on also optimizing the "slowpath" (as network stack
      use-case hits this), but this patchset should provide a good foundation
      for further improvements.  Rest of my patch queue in this area needs some
      more work, but preliminary results are good.  I'm attending Netfilter
      Workshop[2] next week, and I'll hopefully return working on further
      improvements in this area.

      watchdog: rename watchdog_suspend() and watchdog_resume()

      Rename watchdog_suspend() to lockup_detector_suspend() and
      watchdog_resume() to lockup_detector_resume() to avoid confusion with the
      watchdog subsystem and to be consistent with the existing name
      lockup_detector_init().

      Also provide comment blocks to explain the watchdog_running and
      watchdog_suspended variables and their relationship.

      watchdog: introduce watchdog_park_threads() and watchdog_unpark_threads()

      Originally watchdog_nmi_enable(cpu) and watchdog_nmi_disable(cpu) were
      only called in watchdog thread context.  However, the following commits
      utilize these functions outside of watchdog thread context too.

            watchdog: Add watchdog enable/disable all functions

      Hence, it is now possible that these functions execute concurrently with
      the same 'cpu' argument.  This concurrency is problematic because per-cpu
      'watchdog_ev' can be accessed/modified without adequate synchronization.

      The patch series aims to address the above problem.  However, instead of
      introducing locks to protect per-cpu 'watchdog_ev' a different approach is
      taken: Invoke these functions by parking and unparking the watchdog
      threads (to ensure they are always called in watchdog thread context).

        static struct smp_hotplug_thread watchdog_threads = {
                 ...
                .park   = watchdog_disable, // calls watchdog_nmi_disable()
                .unpark = watchdog_enable,  // calls watchdog_nmi_enable()
        };

      Both previously mentioned commits call these functions in a similar way
      and thus in principle contain some duplicate code.  The patch series also
      avoids this duplication by providing a commonly usable mechanism.

      - Patch 1/4 introduces the watchdog_{park|unpark}_threads functions that
        park/unpark all watchdog threads specified in 'watchdog_cpumask'. They
        are intended to be called inside of kernel/watchdog.c only.

      - Patch 2/4 introduces the watchdog_{suspend|resume} functions which can
        be utilized by external callers to deactivate the hard and soft lockup
        detector temporarily.

      - Patch 3/4 utilizes watchdog_{park|unpark}_threads to replace some code
        that was introduced by commit 9809b18fcf6b8d8ec4d3643677345907e6b50eca.

      - Patch 4/4 utilizes watchdog_{suspend|resume} to replace some code that
        was introduced by commit b3738d29323344da3017a91010530cf3a58590fc.

      A few corner cases should be mentioned here for completeness.

      - kthread_park() of watchdog/N could hang if cpu N is already locked up.
        However, if watchdog is enabled the lockup will be detected anyway.

      - kthread_unpark() of watchdog/N could hang if cpu N got locked up after
        kthread_park(). The occurrence of this scenario should be _very_ rare
        in practice, in particular because it is not expected that temporary
        deactivation will happen frequently, and if it happens at all it is
        expected that the duration of deactivation will be short.

      This patch (of 4): introduce watchdog_park_threads() and 
watchdog_unpark_threads()

      These functions are intended to be used only from inside kernel/watchdog.c
      to park/unpark all watchdog threads that are specified in
      watchdog_cpumask.

      The kernel's NMI watchdog has nothing to do with the watchdog subsystem.
      Its header declarations should be in linux/nmi.h, not linux/watchdog.h.

      The code provided two sets of dummy functions if HARDLOCKUP_DETECTOR is

      smpboot: make cleanup to mirror setup

      The per-cpu kthread cleanup() callback is the mirror of the setup()
      callback.  When the per-cpu kthread is started, it first calls setup()
      to initialize the resources which are then released by cleanup() when
      the kthread exits.

      Now since the introduction of a per-cpu kthread cpumask, the kthreads
      excluded by the cpumask on boot may happen to be parked immediately
      after their creation without taking the setup() stage, waiting to be
      asked to unpark to do so.  Then when smpboot_unregister_percpu_thread()
      is later called, the kthread is stopped without having ever called
      setup().

      But this triggers a bug as the kthread unconditionally calls cleanup()
      on exit but this doesn't mirror any setup().  Thus the kernel crashes
      because we try to free resources that haven't been initialized, as in
      the watchdog case:

          WATCHDOG disable 0
          WATCHDOG disable 1
          WATCHDOG disable 2
          BUG: unable to handle kernel NULL pointer dereference at

          IP: hrtimer_active+0x26/0x60
          [...]
          Call Trace:
            hrtimer_try_to_cancel+0x1c/0x280
            hrtimer_cancel+0x1d/0x30

            kthread+0xf8/0x110
            ret_from_fork+0x3f/0x70

      This bug is currently masked with explicit kthread unparking before
      kthread_stop() on smpboot_destroy_threads(). This forces a call to
      setup() and then unpark().

      We could fix this by unconditionally calling setup() on kthread entry.
      But setup() isn't always cheap.  In the case of watchdog it launches
      hrtimer, perf events, etc...  So we may as well like to skip it if there
      are chances the kthread will never be used, as in a reduced cpumask value.

      So let's simply do a state machine check before calling cleanup() that
      makes sure setup() has been called before mirroring it.

      And remove the nasty hack workaround.

      fs: create and use seq_show_option for escaping

      Many file systems that implement the show_options hook fail to correctly
      escape their output which could lead to unescaped characters (e.g.  new
      lines) leaking into /proc/mounts and /proc/[pid]/mountinfo files.  This
      could lead to confusion, spoofed entries (resulting in things like
      systemd issuing false d-bus "mount" notifications), and who knows what
      else.  This looks like it would only be the root user stepping on
      themselves, but it's possible weird things could happen in containers or
      in other situations with delegated mount privileges.

      Here's an example using overlay with setuid fusermount trusting the
      contents of /proc/mounts (via the /etc/mtab symlink).  Imagine the use
      of "sudo" is something more sneaky:

        $ BASE="ovl"
        $ MNT="$BASE/mnt"
        $ LOW="$BASE/lower"
        $ UP="$BASE/upper"
        $ WORK="$BASE/work/ 0 0
        none /proc fuse.pwn user_id=1000"
        $ mkdir -p "$LOW" "$UP" "$WORK"
        $ sudo mount -t overlay -o "lowerdir=$LOW,upperdir=$UP,workdir=$WORK" 
none /mnt
        $ cat /proc/mounts
        none /root/ovl/mnt overlay 
rw,relatime,lowerdir=ovl/lower,upperdir=ovl/upper,workdir=ovl/work/ 0 0
        none /proc fuse.pwn user_id=1000 0 0
        $ fusermount -u /proc
        $ cat /proc/mounts
        cat: /proc/mounts: No such file or directory

      This fixes the problem by adding new seq_show_option and
      seq_show_option_n helpers, and updating the vulnerable show_option
      handlers to use them as needed.  Some, like SELinux, need to be open
      coded due to unusual existing escape mechanisms.

      ocfs2: do not set fs read-only if rec[0] is empty while committing 
truncate

      While appending an extent to a file, it will call these functions:
      ocfs2_insert_extent

        -> call ocfs2_grow_tree() if there's no free rec
           -> ocfs2_add_branch add a new branch to extent tree,
              now rec[0] in the leaf of rightmost path is empty
        -> ocfs2_do_insert_extent
           -> ocfs2_rotate_tree_right
             -> ocfs2_extend_rotate_transaction
                -> jbd2_journal_restart if jbd2_journal_extend fail
           -> ocfs2_insert_path
              -> ocfs2_extend_trans
                -> jbd2_journal_restart if jbd2_journal_extend fail
              -> ocfs2_insert_at_leaf
           -> ocfs2_et_update_clusters
      Function jbd2_journal_restart() may be called and it may happened that
      buffers dirtied in ocfs2_add_branch() are committed
      while buffers dirtied in ocfs2_insert_at_leaf() and
      ocfs2_et_update_clusters() are not.
      So an empty rec[0] is left in rightmost path which will cause
      read-only filesystem when call ocfs2_commit_truncate()
      with the error message: "Inode %lu has an empty extent record".

      This is not a serious problem, so remove the rightmost path when call
      ocfs2_commit_truncate().

      ocfs2: call ocfs2_journal_access_di() before ocfs2_journal_dirty() in 
ocfs2_write_end_nolock()

      1: After we call ocfs2_journal_access_di() in ocfs2_write_begin(),
         jbd2_journal_restart() may also be called, in this function transaction
         A's t_updates-- and obtains a new transaction B.  If
         jbd2_journal_commit_transaction() is happened to commit transaction A,
         when t_updates==0, it will continue to complete commit and unfile
         buffer.

         So when jbd2_journal_dirty_metadata(), the handle is pointed a new
         transaction B, and the buffer head's journal head is already freed,
         jh->b_transaction == NULL, jh->b_next_transaction == NULL, it returns
         EINVAL, So it triggers the BUG_ON(status).

          ocfs2_journal_dirty
              jbd2_journal_dirty_metadata(bug)
         ocfs2_commit_trans

      2.  In ext4, I found that: jbd2_journal_get_write_access() called by
         ext4_write_end.

      ext4_write_begin
          ext4_journal_start
              __ext4_journal_start_sb
                  ext4_journal_check_start
                  jbd2__journal_start

      ext4_write_end
          ext4_mark_inode_dirty
              ext4_reserve_inode_write
                  ext4_journal_get_write_access
                      jbd2_journal_get_write_access
              ext4_mark_iloc_dirty
                  ext4_do_update_inode
                      ext4_handle_dirty_metadata
                          jbd2_journal_dirty_metadata

      3. So I think we should put ocfs2_journal_access_di before
         ocfs2_journal_dirty in the ocfs2_write_end.  and it works well after my
         modification.

      ocfs2: use 64bit variables to track heartbeat time

      o2hb_elapsed_msecs computes the time taken for a disk heartbeat.
      'struct timeval' variables are used to store start and end times.  On
      32-bit systems, the 'tv_sec' component of 'struct timeval' will overflow
      in year 2038 and beyond.

      This patch solves the overflow with the following:

      1. Replace o2hb_elapsed_msecs using 'ktime_t' values to measure start
         and end time, and built-in function 'ktime_ms_delta' to compute the
         elapsed time.  ktime_get_real() is used since the code prints out the
         wallclock time.

      2. Changes format string to print time as a single 64-bit nanoseconds
         value ("%lld") instead of seconds and microseconds.  This simplifies
         the code since converting ktime_t to that format would need expensive
         computation.  However, the debug log string is less readable than the
         previous format.

      ocfs2: fix race between crashed dio and rm

      There is a race case between crashed dio and rm, which will lead to
      OCFS2_VALID_FL not set read-only.

                                        ocfs2_remove_inode
                                        recover N1 and read the corrupted inode,
                                        and set filesystem read-only

      So we skip the inode deletion this time and wait for dio entry recovered
      first.

      ocfs2: avoid access invalid address when read o2dlm debug messages

      The following case will lead to a lockres is freed but is still in use.

      cat /sys/kernel/debug/o2dlm/locking_state dlm_thread
      lockres_seq_start
          -> lock dlm->track_lock
          -> get resA
                                                      resA->refs decrease to 0,
                                                      call dlm_lockres_release,
                                                      and wait for "cat" unlock.
      Although resA->refs is already set to 0,
      increase resA->refs, and then unlock
                                                      lock dlm->track_lock
                                                          -> list_del_init()
                                                          -> unlock
                                                          -> free resA

      In such a race case, invalid address access may occurs.  So we should
      delete list res->tracking before resA->refs decrease to 0.

      ocfs2: take inode lock in ocfs2_iop_set/get_acl()

      This bug in mainline code is pointed out by Mark Fasheh.  When
      ocfs2_iop_set_acl() and ocfs2_iop_get_acl() are entered from VFS layer,
      inode lock is not held.  This seems to be regression from older kernels.
      The patch is to fix that.

      assert is tripped because the tran is not checkpointed and the lock level

      Some time ago, chmod command had been executed. As result, the following

      184                 handle = ocfs2_start_trans(OCFS2_SB(inode->i_sb),
      185                                            
OCFS2_INODE_UPDATE_CREDITS);

      ocfs2_setattr.#1247 we unlock and at #1259 call posix_acl_chmod. When we 
reach
      ocfs2_acl_set_mode.#181 and do trans, the inode cluster lock is not held 
in EX
      mode (it should be). How this could have happended?

      We are the lock master, were holding lock EX and have released it in
      ocfs2_setattr.#1247.  Note that there are no holders of this lock at
      this point.  Another node needs the lock in PR, and we downconvert from
      EX to PR.  So the inode lock is PR when do the trans in
      ocfs2_acl_set_mode.#184.  The trans stays in core (not flushed to disc).
      Now another node want the lock in EX, downconvert thread gets kicked
      (the one that tripped assert abovt), finds an unflushed trans but the
      lock is not EX (it is PR).  If the lock was at EX, it would have flushed
      the trans ocfs2_ci_checkpointed -> ocfs2_start_checkpoint before
      downconverting (to NULL) for the request.

      ocfs2_setattr must not drop inode lock ex in this code path.  If it
      does, takes it again before the trans, say in ocfs2_set_acl, another
      cluster node can get in between, execute another setattr, overwriting
      the one in progress on this node, resulting in a mode acl size combo
      that is a mix of the two.

      ocfs2: fix a tiny case that inode can not removed

      When running dirop_fileop_racer we found a case that inode
      can not removed.

      Two nodes, say Node A and Node B, mount the same ocfs2 volume.  Create
      two dirs /race/1/ and /race/2/ in the filesystem.

        Node A                            Node B
        rm -r /race/2/
                                          mv /race/1/ /race/2/
        call ocfs2_unlink(), get
        the EX mode of /race/2/
                                          wait for B unlock /race/2/
        decrease i_nlink of /race/2/ to 0,
        and add inode of /race/2/ into
        orphan dir, unlock /race/2/
                                          got EX mode of /race/2/. because
                                          /race/1/ is dir, so inc i_nlink
                                          of /race/2/ and update into disk,
                                          unlock /race/2/
        because i_nlink of /race/2/
        is not zero, this inode will
        always remain in orphan dir

      This patch fixes this case by test whether i_nlink of new dir is zero.

      ocfs2: add ip_alloc_sem in direct IO to protect allocation changes

      In ocfs2, ip_alloc_sem is used to protect allocation changes on the
      node.  In direct IO, we add ip_alloc_sem to protect date consistent
      between direct-io and ocfs2_truncate_file race (buffer io use
      ip_alloc_sem already).  Although inode->i_mutex lock is used to avoid
      concurrency of above situation, i think ip_alloc_sem is still needed
      because protect allocation changes is significant.

      Other filesystem like ext4 also uses rw_semaphore to protect data
      consistent between get_block-vs-truncate race by other means, So
      ip_alloc_sem in ocfs2 direct io is needed.

      ocfs2: add errors=continue

      OCFS2 is often used in high-availaibility systems.  However, ocfs2
      converts the filesystem to read-only at the drop of the hat.  This may
      not be necessary, since turning the filesystem read-only would affect
      other running processes as well, decreasing availability.

      This attempt is to add errors=continue, which would return the EIO to
      the calling process and terminate furhter processing so that the
      filesystem is not corrupted further.  However, the filesystem is not
      converted to read-only.

      As a future plan, I intend to create a small utility or extend
      fsck.ocfs2 to fix small errors such as in the inode.  The input to the
      utility such as the inode can come from the kernel logs so we don't have
      to schedule a downtime for fixing small-enough errors.

      The patch changes the ocfs2_error to return an error.  The error
      returned depends on the mount option set.  If none is set, the default
      is to turn the filesystem read-only.

      Perhaps errors=continue is not the best option name.  Historically it is
      used for making an attempt to progress in the current process itself.
      Should we call it errors=eio? or errors=killproc? Suggestions/Comments
      welcome.

      ocfs2: flush inode data to disk and free inode when i_count becomes zero

      Disk inode deletion may be heavily delayed when one node unlink a file
      after the same dentry is freed on another node(say N1) because of memory
      shrink but inode is left in memory.  This inode can only be freed while
      N1 doing the orphan scan work.

      However, N1 may skip orphan scan for several times because other nodes
      may do the work earlier.  In our tests, it may take 1 hour on 4 nodes
      cluster and it hurts the user experience.  So we think the inode should
      be freed after the data flushed to disk when i_count becomes zero to
      avoid such circumstances.

      ocfs2: set filesytem read-only when ocfs2_delete_entry failed.

      In ocfs2_rename, it will lead to an inode with two entried(old and new) if
      ocfs2_delete_entry(old) failed.  Thus, filesystem will be inconsistent.

      The case is described below:

      ocfs2_rename
          -> ocfs2_start_trans
          -> ocfs2_add_entry(new)
          -> ocfs2_delete_entry(old)
              -> __ocfs2_journal_access *failed* because of -ENOMEM
          -> ocfs2_commit_trans

      So filesystem should be set to read-only at the moment.

      be deleted twice and thus trigger the BUG when validating
      OCFS2_DIO_ORPHANED_FL in ocfs2_del_inode_from_orphan.

          >>>>>>>> race window.
                   1) another node may rm the file and then down, this node
                   take care of orphan recovery and clear flag
                   OCFS2_DIO_ORPHANED_FL.
                   2) since rw lock is unlocked, it may race with another
                   orphan recovery and append dio.
          ocfs2_del_inode_from_orphan

      So take inode mutex lock when recovering orphans and make rw unlock at the
      end of aio write in case of append dio.

      Fix it by chopping starting and ending parenthesis from the each symbol

      As a side note, this probably comes from the function
      dump_backtrace_entry(), which is implemented differently for each
      architecture.  That makes a single decoding script a bit a challenge.

      kerneldoc: Convert error messages to GNU error message format

      Editors like emacs and vi recognize a number of error message formats.
      The format used by the kerneldoc tool is not recognized by emacs.

      Change the kerneldoc error message format to the GNU style such that the
      emacs prev-error and next-error commands can be used to navigate through
      kerneldoc error messages.  For more information about the GNU error
      message format, see also

      fsnotify: get rid of fsnotify_destroy_mark_locked()

      fsnotify_destroy_mark_locked() is subtle to use because it temporarily
      releases group->mark_mutex.  To avoid future problems with this
      function, split it into two.

      fsnotify_detach_mark() is the part that needs group->mark_mutex and
      fsnotify_free_mark() is the part that must be called outside of
      group->mark_mutex.  This way it's much clearer what's going on and we
      also avoid some pointless acquisitions of group->mark_mutex.

      fs/notify: optimize inotify/fsnotify code for unwatched files

      I have a _tiny_ microbenchmark that sits in a loop and writes single
      bytes to a file.  Writing one byte to a tmpfs file is around 2x slower
      than reading one byte from a file, which is a _bit_ more than I expecte.
      This is a dumb benchmark, but I think it's hard to deny that write() is
      a hot path and we should avoid unnecessary overhead there.

      I did a 'perf record' of 30-second samples of read and write.  The top
      item in a diffprofile is srcu_read_lock() from fsnotify().  There are
      active inotify fd's from systemd, but nothing is actually listening to
      the file or its part of the filesystem.

      I *think* we can avoid taking the srcu_read_lock() for the common case
      where there are no actual marks on the file.  This means that there will
      both be nothing to notify for *and* implies that there is no need for
      clearing the ignore mask.

      This patch gave a 13.1% speedup in writes/second on my test, which is an
      improvement from the 10.8% that I saw with the last version.

      drivers/video/concole: add negative dependency for VGA_CONSOLE on ARC

      Architectures which support VGA console must define screen_info
      structurture from "uapi/linux/screen_info.h".  Otherwise undefined
      symbol error occurs.  Usually it's defined in "setup.c" for each
      architecture.

      If an architecture does not support VGA console (ARC's case) there are 2
      ways: define a dummy instance of screen_info or add a negative
      dependency for VGA_CONSOLE in to prevent selecting this option.

      I've implemented the second way.  However the best solution is to add
      HAVE_VGA_CONSOLE option for targets which support VGA console.  Then
      turn off VGA_CONSOLE by default and add dependency to HAVE_VGA_CONSOLE.
      But right now it's better to just add a negative dependency for ARC and
      then consider how to collaborate about this issue with maintainers of
      other architectures.

      capabilities: ambient capabilities

      Credit where credit is due: this idea comes from Christoph Lameter with
      a lot of valuable input from Serge Hallyn.  This patch is heavily based
      on Christoph's patch.

      ===== The status quo =====

      On Linux, there are a number of capabilities defined by the kernel.  To
      perform various privileged tasks, processes can wield capabilities that
      they hold.

      Each task has four capability masks: effective (pE), permitted (pP),
      inheritable (pI), and a bounding set (X).  When the kernel checks for a
      capability, it checks pE.  The other capability masks serve to modify
      what capabilities can be in pE.

      Any task can remove capabilities from pE, pP, or pI at any time.  If a
      task has a capability in pP, it can add that capability to pE and/or pI.
      If a task has CAP_SETPCAP, then it can add any capability to pI, and it
      can remove capabilities from X.

      Tasks are not the only things that can have capabilities; files can also
      have capabilities.  A file can have no capabilty information at all [1].
      If a file has capability information, then it has a permitted mask (fP)
      and an inheritable mask (fI) as well as a single effective bit (fE) [2].
      File capabilities modify the capabilities of tasks that execve(2) them.

      A task that successfully calls execve has its capabilities modified for
      the file ultimately being excecuted (i.e.  the binary itself if that
      binary is ELF or for the interpreter if the binary is a script.) [3] In
      the capability evolution rules, for each mask Z, pZ represents the old
      value and pZ' represents the new value.  The rules are:

        pP' = (X & fP) | (pI & fI)
        pI' = pI
        pE' = (fE ? pP' : 0)
        X is unchanged

      For setuid binaries, fP, fI, and fE are modified by a moderately
      complicated set of rules that emulate POSIX behavior.  Similarly, if
      euid == 0 or ruid == 0, then fP, fI, and fE are modified differently
      (primary, fP and fI usually end up being the full set).  For nonroot
      users executing binaries with neither setuid nor file caps, fI and fP
      are empty and fE is false.

      As an extra complication, if you execute a process as nonroot and fE is
      set, then the "secure exec" rules are in effect: AT_SECURE gets set,
      LD_PRELOAD doesn't work, etc.

      This is rather messy.  We've learned that making any changes is
      dangerous, though: if a new kernel version allows an unprivileged
      program to change its security state in a way that persists cross
      execution of a setuid program or a program with file caps, this
      persistent state is surprisingly likely to allow setuid or file-capped
      programs to be exploited for privilege escalation.

      ===== The problem =====

      Capability inheritance is basically useless.

      If you aren't root and you execute an ordinary binary, fI is zero, so
      your capabilities have no effect whatsoever on pP'.  This means that you
      can't usefully execute a helper process or a shell command with elevated
      capabilities if you aren't root.

      On current kernels, you can sort of work around this by setting fI to
      the full set for most or all non-setuid executable files.  This causes
      pP' = pI for nonroot, and inheritance works.  No one does this because
      it's a PITA and it isn't even supported on most filesystems.

      If you try this, you'll discover that every nonroot program ends up with
      secure exec rules, breaking many things.

      This is a problem that has bitten many people who have tried to use
      capabilities for anything useful.

      ===== The proposed change =====

      This patch adds a fifth capability mask called the ambient mask (pA).
      pA does what most people expect pI to do.

      pA obeys the invariant that no bit can ever be set in pA if it is not
      set in both pP and pI.  Dropping a bit from pP or pI drops that bit from
      pA.  This ensures that existing programs that try to drop capabilities
      still do so, with a complication.  Because capability inheritance is so
      broken, setting KEEPCAPS, using setresuid to switch to nonroot uids, and
      then calling execve effectively drops capabilities.  Therefore,
      setresuid from root to nonroot conditionally clears pA unless
      SECBIT_NO_SETUID_FIXUP is set.  Processes that don't like this can
      re-add bits to pA afterwards.

      The capability evolution rules are changed:

        pA' = (file caps or setuid or setgid ? 0 : pA)
        pP' = (X & fP) | (pI & fI) | pA'
        pI' = pI
        pE' = (fE ? pP' : pA')
        X is unchanged

      If you are nonroot but you have a capability, you can add it to pA.  If
      you do so, your children get that capability in pA, pP, and pE.  For
      example, you can set pA = CAP_NET_BIND_SERVICE, and your children can
      automatically bind low-numbered ports.  Hallelujah!

      Unprivileged users can create user namespaces, map themselves to a
      nonzero uid, and create both privileged (relative to their namespace)
      and unprivileged process trees.  This is currently more or less
      impossible.  Hallelujah!

      You cannot use pA to try to subvert a setuid, setgid, or file-capped
      program: if you execute any such program, pA gets cleared and the
      resulting evolution rules are unchanged by this patch.

      Users with nonzero pA are unlikely to unintentionally leak that
      capability.  If they run programs that try to drop privileges, dropping
      privileges will still work.

      It's worth noting that the degree of paranoia in this patch could
      possibly be reduced without causing serious problems.  Specifically, if
      we allowed pA to persist across executing non-pA-aware setuid binaries
      and across setresuid, then, naively, the only capabilities that could
      leak as a result would be the capabilities in pA, and any attacker
      *already* has those capabilities.  This would make me nervous, though --
      setuid binaries that tried to privilege-separate might fail to do so,
      and putting CAP_DAC_READ_SEARCH or CAP_DAC_OVERRIDE into pA could have
      unexpected side effects.  (Whether these unexpected side effects would
      be exploitable is an open question.) I've therefore taken the more
      paranoid route.  We can revisit this later.

      An alternative would be to require PR_SET_NO_NEW_PRIVS before setting
      ambient capabilities.  I think that this would be annoying and would
      make granting otherwise unprivileged users minor ambient capabilities
      (CAP_NET_BIND_SERVICE or CAP_NET_RAW for example) much less useful than
      it is with this patch.

      ===== Footnotes =====

      [1] Files that are missing the "security.capability" xattr or that have
      unrecognized values for that xattr end up with has_cap set to false.
      The code that does that appears to be complicated for no good reason.

      [2] The libcap capability mask parsers and formatters are dangerously
      misleading and the documentation is flat-out wrong.  fE is *not* a mask;
      it's a single bit.  This has probably confused every single person who
      has tried to use file capabilities.

      [3] Linux very confusingly processes both the script and the interpreter
      if applicable, for reasons that elude me.  The results from thinking
      about a script's file capabilities and/or setuid bits are mostly
      discarded.

      Preliminary userspace code is here, but it needs updating:
      
https://git.kernel.org/cgit/linux/kernel/git/luto/util-linux-playground.git/commit/?h=cap_ambient&id=7f5afbd175d2

      Here is a test program that can be used to verify the functionality
      (from Christoph):

      kernel/kthread.c:kthread_create_on_node(): clarify documentation

      - Make it clear that the `node' arg refers to memory allocations only:
        kthread_create_on_node() does not pin the new thread to that node's
        CPUs.

      - Encourage the use of NUMA_NO_NODE.

      mm: check if section present during memory block registering

      Tony Luck found on his setup, if memory block size 512M will cause crash
      during booting.

           topology_init+0x3c/0x95
           do_one_initcall+0xcd/0x1f0

      The system has non continuous RAM address:
       BIOS-e820: [mem 0x0000001300000000-0x0000001cffffffff] usable

      So there are start sections in memory block not present.  For example:

          memory block : [0x2c18000000, 0x2c20000000) 512M

      first three sections are not present.

      The current register_mem_sect_under_node() assume first section is
      present, but memory block section number range [start_section_nr,
      end_section_nr] would include not present section.

      For arch that support vmemmap, we don't setup memmap for struct page
      area within not present sections area.

      So skip the pfn range that belong to absent section.

      ocfs2: direct write will call ocfs2_rw_unlock() twice when doing aio+dio

      ocfs2_file_write_iter() is usng the wrong return value ('written').  This
      will cause ocfs2_rw_unlock() be called both in write_iter & end_io,

      memory-hotplug: add hot-added memory ranges to memblock before allocate 
node_data for a node.

      Commit f9126ab9241f ("memory-hotplug: fix wrong edge when hot add a new
      node") hot-added memory range to memblock, after creating pgdat for new
      node.

      But there is a problem:

        add_memory()
        |--> hotadd_new_pgdat()
             |--> free_area_init_node()
                  |--> get_pfn_range_for_nid()
                       |--> find start_pfn and end_pfn in memblock
        |--> ......
        |--> memblock_add_node(start, size, nid)    --------    Here, just too 
late.

      get_pfn_range_for_nid() will find that start_pfn and end_pfn are both 0.
      As a result, when adding memory, dmesg will give the following wrong
      message.

        Initmem setup node 5 [mem 0x0000000000000000-0xffffffffffffffff]
        On node 5 totalpages: 0
        Built 5 zonelists in Node order, mobility grouping on.  Total pages: 
32588823
        Policy zone: Normal
        init_memory_mapping: [mem 0x60000000000-0x607ffffffff]

      The solution is simple, just add the memory range to memblock a little
      earlier, before hotadd_new_pgdat().

      CRIS: fix switch_mm() lockdep splat

      With lockdep support implemented on CRISv32, we get the following splat.
      switch_mm() can be called both from the scheduler() (with interrupts
      disabled) and from flush_old_exec (via activate_mm()), with interrupts
      enabled.  Fix it by disabling interrupts in activate_mm(), similar to
      powerpc and hexagon.

      Revert "NFS: Make close(2) asynchronous when closing NFS O_DIRECT files"

      This reverts commit f895c53f8ace3c3e49ebf9def90e63fc6d46d2bf.

      This commit causes a NFSv4 regression in that close()+unlink() can end
      up failing. The reason is that we no longer have a guarantee that the
      CLOSE has completed on the server, meaning that the subsequent call to
      REMOVE may fail with NFS4ERR_FILE_OPEN if the server implements Windows
      unlink() semantics.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

      Pull sound updates from Takashi Iwai:
       "There are little changes in core part, but lots of development are
        found in drivers, especially ASoC.  The diffstat shows regmap-related
        changes for a slight API additions / changes, and that's all.

        Looking at the code size statistics, the most significant addition is
        for Intel Skylake.  (Note that SKL support is still underway, the
        codec driver is missing.) Also STI controller driver is a major
        addition as well as a few new codec drivers.

        In HD-audio side, there are fewer changes than the past.  The
        noticeable change is the support of ELD notification from i915
        graphics driver.  Thus this pull request carries a few changes in
        drm/i915.

        Other than that, USB-audio got a rewrite of runtime PM code.  It was
        initiated by lockdep warning, but resulted in a good cleanup in the
        end.

        Below are the highlights:

        Common:
         - Factoring out of AC'97 reset code from ASoC into the core helper
         - A few regmap API extensions (in case it's not pulled yet)

        ASoC:
         - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
           RT298 and ST STI controllers
         - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
           RT5650
         - Initial driver support for Intel Skylake devices
         - Lots of rsnd cleanup and enhancements
         - A few DAPM fixes and cleanups
         - A large number of cleanups in various drivers (conversion and
           standardized to regmap, component) mostly by Lars-Peter and Axel

        HD-audio:
         - Extended HD-audio core for Intel Skylake controller support
         - Quirks for Dell headsets, Alienware 15
         - Clean up of pin-based quirk tables for Realtek codecs
         - ELD notifier implenetation for Intel HDMI/DP

        the sorting be a true sort, not this mismash.

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for the v4.3 development
        cycle.

        Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
        the overall tempo of the kernel v4.3 will be a gigantic diff.

      [ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
        we'll see - Linus ]

        Core changes:

         - It is possible configure groups in debugfs.

         - Consolidation of chained IRQ handler install/remove replacing all
           call sites where irq_set_handler_data() and
           irq_set_chained_handler() were done in succession with a combined
           call to irq_set_chained_handler_and_data().  This series was
           created by Thomas Gleixner after the problem was observed by
           Russell King.

         - Tglx also made another series of patches switching
           __irq_set_handler_locked() for irq_set_handler_locked() which is
           way cleaner.

         - Tglx also wrote a good bunch of patches to make use of
           irq_desc_get_xxx() accessors and avoid looking up irq_descs from
           IRQ numbers.  The goal is to get rid of the irq number from the
           handlers in the IRQ flow which is nice.

        Driver feature enhancements:

         - Power management support for the SiRF SoC Atlas 7.

         - Power down support for the Qualcomm driver.

         - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
           in IRQ handlers to play nice with the realtime patch set.

         - Rework and new modes handling for Qualcomm SPMI-MPP.

         - Pinconf power source config for SH PFC.

        New drivers and subdrivers:

         - A new driver for Conexant Digicolor CX92755.

         - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
           ProXtream2 and PH1-LD6b SoC pin control support.

         - Reverse-egineered the S/PDIF settings for the Allwinner sun4i
           driver.

         - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs

         - A new Freescale i.mx6ul subdriver.

        Cleanup:

         - Remove platform data support in a number of SH PFC subdrivers"

      Merge tag 'gpio-v4.3-1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.3 kernel cycle.

        There is quite a lot going on in the GPIO subsystem this merge window,
        so the main matter is decribed below.

        The hits in other subsystems when making the GPIO flags optional are
        all ACKed by their respective subsystem maintainers.

        Core changes:

         - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
           of the descriptor calls that did not use the flags argument on the
           end.  This was around for too long and eventually Uwe Kleine-König
           took the time to clean it out and the last users are removed along
           with the macros in this tag.  In several cases the use of flags
           simplifies the code.  For this reason we have (ACKed) patches
           hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
           nail with removing the macros.

         - Add a fat document describing how much ready-made GPIO stuff we
           have i the kernel to discourage people from reinventing a square
           wheel in userspace, as so often happens.

         - Create a separate lockdep class for each instance of a GPIO IRQ
           chip instead of using one class for all chips, as the current code
           will not work with systems with several GPIO chips doing lockdep
           debugging.

         - Protect against driver unloading also when a GPIO line is only used
           as IRQ for the GPIOLIB_IRQCHIP helpers.

         - If the GPIO chip has no designated owner, assign the parent device
           driver owner as owner.

         - Consolidation of chained IRQ handler install/remove replacing all
           call sites where irq_set_handler_data() and
           irq_set_chained_handler() were done in succession with a combined
           call to irq_set_chained_handler_and_data().

           This series was created by Thomas Gleixner after the problem was
           observed by Russell King.

         - Tglx also made another series of patches switching
           __irq_set_handler_locked() for irq_set_handler_locked() which is
           way cleaner.

         - Tglx and Jiang Liu wrote a good bunch of patches to make use of
           irq_desc_get_xxx() accessors and avoid looking up irq_descs from
           IRQ numbers.  The goal is to get rid of the irq number from the
           handlers in the IRQ flow which is nice.

         - Rob Herring killed off the set_irq_flags() for all GPIO drivers.
           This was an ARM specific function that is replaced with the generic
           irq_modify_status() where special flags are actually needed.

         - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
           if the pin controller isn't available.  Pretty logical, yet needed
           to be fixed.

         - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
           back, then call these instead of the defaults provided by the
           GPIOLIB.

         - Fix an undocumented ABI hole: named GPIOs were not properly
           documented.

        Driver improvements:

         - Add get_direction() support to the generic GPIO driver, it's
           strange that we didn't have that before.

         - Make it possible to have input-only GPIO chips using the generic
           GPIO driver.

         - Clean out platform data support from the Emma Mobile (EM) driver

         - Finegrained runtime PM support for the RCAR driver.

         - Support r8a7795 (R-car H3) in the RCAR driver.

         - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.

         - Some consolidation and new support in the MPC8xxx driver, we now
           support MPC5125.

         - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
           spinlocks making it work better with the realime patches.

         - Interrupt support for the EXTRAXFS GPIO driver.

         - Make the ETRAXFS GPIO driver support also ARTPEC-3.

         - Interrupt and wakeup support for the BRCMSTB driver, also for
           wakeup from S5 cold boot.

         - Mask MXC IRQs during suspend.

         - Improve OMAP2 GPIO set_debounce() to work according to spec.

         - The VF610 driver handles IRQs properly.

        New drivers:

         - ZTE ZX GPIO driver"

      arm/arm64: KVM: vgic: Move active state handling to flush_hwstate

      We currently set the physical active state only when we *inject* a new
      pending virtual interrupt, but this is actually not correct, because we
      could have been preempted and run something else on the system that
      resets the active state to clear.  This causes us to run the VM with the
      timer set to fire, but without setting the physical active state.

      The solution is to always check the LR configurations, and we if have a
      mapped interrupt in the LR in either the pending or active state
      (virtual), then set the physical active state.

      doesn't allocate needed space for ghash_async_ctx, so any

      mac80211: reject software RSSI CQM with beacon filtering

      When beacon filtering is enabled the mac80211 software implementation
      for RSSI CQM cannot work as beacons will not be available. Rather than
      accepting such a configuration without proper effect, reject it.

      mac80211: avoid VHT usage with no 80MHz chans allowed

      Currently if 80MHz channels are not allowed for use, the VHT IE is not
      included in the probe request for an AP. This is not good enough if the
      AP is configured with the wrong regulatory and supports VHT even where
      prohibited or in TDLS scenarios.
      Mark the ifmgd with the DISABLE_VHT flag for the misbehaving-AP case, and
      unset VHT support from the peer-station entry for the TDLS case.

      cfg80211: regulatory: restore proper user alpha2

      restore_regulatory_settings() should restore alpha2
      as computed in restore_alpha2(), not raw user_alpha2 to
      behave as described in the comment just above that code.

      This fixes endless loop of calling CRDA for "00" and "97"
      countries after resume from suspend on my laptop.

      Looks like others had the same problem, too:

      mac80211: protect non-HT BSS when HT TDLS traffic exists

      HT TDLS traffic should be protected in a non-HT BSS to avoid
      collisions. Therefore, when TDLS peers join/leave, check if
      protection is (now) needed and set the ht_operation_mode of
      the virtual interface according to the HT capabilities of the
      TDLS peer(s).

      This works because a non-HT BSS connection never sets (or
      otherwise uses) the ht_operation_mode; it just means that
      drivers must be aware that this field applies to all HT
      traffic for this virtual interface, not just the traffic
      within the BSS. Document that.

      mac80211: Do not use sizeof() on pointer type

      The rate_control_cap_mask() function takes a parameter mcs_mask, which
      GCC will take to be u8 * even though it was declared with a fixed size.
      This causes the following warning:

        net/mac80211/rate.c: In function 'rate_control_cap_mask':
        net/mac80211/rate.c:719:25: warning: 'sizeof' on array function 
parameter 'mcs_mask' will return size of 'u8 * {aka unsigned char *}' 
[-Wsizeof-array-argument]
           for (i = 0; i < sizeof(mcs_mask); i++)
                                 ^

                  ^

      This can be easily fixed by using the IEEE80211_HT_MCS_MASK_LEN directly
      within the loop condition.

      kbuild: Fix clang detection

      We cannot detect clang before including the arch Makefile, because that
      can set the default cross compiler. We also cannot detect clang after
      including the arch Makefile, because powerpc wants to know about clang.
      Solve this by using an deferred variable. This costs us a few shell
      invocations, but this is only a constant number.

      deb-pkg: add source package

      Make deb-pkg build both source and binary package like make rpm-pkg does.
      For people who only need binary kernel package, there is now bindeb-pkg
      target, same target also used to build the .deb files if built from the
      source package using dpkg-buildpackage.

      Generated source package will build the same kernel .config than what
      was available for make deb-pkg. The name of the source package can
      be set with KDEB_SOURCENAME enviroment variable.

      The source package is useful for GPL compliance, or for feeding to a
      automated debian package builder.

      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

        - In some cases where perf_event.fork.{pid,tid} should be used we were 
instead
          using perf_event.comm.{pid,tid}, which is not a problem for for the 
'pid'
          case, that sits in the same place in these union_perf_event members, 
but
          comm.tid sits where fork.ppid is, oops.

          These cases were considered as (potentially) problematic:

           - 'perf script' with !sample_id_all, i.e. only non old kernels 
without
              perf_event_attr.sample_id_all.

           - intel_pt could be affected when decoding without timestamps, as 
the exit
             event is only used to flush out data which anyway gets flushed at 
the
             end of the session.

           - intel_bts also uses the exit event to flush data which would 
probably not
             cause errors as it would get flushed at the end of the session 
instead.

          Fix it. (Adrian Hunter)

        - Due to relaxing the compiler checks for bison generated files, we 
missed
          updating one parse_events_add_pmu() caller when this function had its

      Input: evdev - do not report errors form flush()

      We've got bug reports showing the old systemd-logind (at least
      system-210) aborting unexpectedly, and this turned out to be because
      of an invalid error code from close() call to evdev devices.  close()
      is supposed to return only either EINTR or EBADFD, while the device
      returned ENODEV.  logind was overreacting to it and decided to kill
      itself when an unexpected error code was received.  What a tragedy.

      The bad error code comes from flush fops, and actually evdev_flush()
      returns ENODEV when device is disconnected or client's access to it is
      revoked. But in these cases the fact that flush did not actually happen is
      not an error, but rather normal behavior. For non-disconnected devices
      result of flush is also not that interesting as there is no potential of
      data loss and even if it fails application has no way of handling the
      error. Because of that we are better off always returning success from
      evdev_flush().

      Also returning EINTR from flush()/close() is discouraged (as it is not
      clear how application should handle this error), so let's stop taking
      evdev->mutex interruptibly.

      security/device_cgroup: Fix RCU_LOCKDEP_WARN() condition

      f78f5b90c4ff ("rcu: Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN()")
      introduced a bug by incorrectly inverting the condition when moving from
      rcu_lockdep_assert() to RCU_LOCKDEP_WARN().  This commit therefore fixes
      the inversion.

      Pull MIPS updates from Ralf Baechle:
       "This is the main pull request for 4.3 for MIPS.  Here's the summary:

        Three fixes that didn't make 4.2-stable:

         - a -Os build might compile the kernel using the MIPS16 instruction
           set but the R2 optimized inline functions in <uapi/asm/swab.h> are
           implemented using 32-bit wide instructions which is invalid.

         - a build error in pgtable-bits.h for a particular kernel
           configuration.

         - accessing registers of the CM GCR might have been compiled to use
           64 bit accesses but these registers are onl 32 bit wide.

        And also a few new bits:

         - move the ATH79 GPIO driver to drivers/gpio

         - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
           change ATH79 accordingly.

         - fix definition of pgprot_writecombine

         - add an implementation of dma_map_ops.mmap

         - fix alignment of quiet build output for vmlinuz link

         - BCM47xx: Use kmemdup rather than duplicating its implementation

         - Netlogic: Fix 0x0x prefixes of constants.

         - merge Bjorn Helgaas' series to remove most of the weak keywords
           from function declarations.

         - CP0 and CP1 registers are best considered treated as unsigned
           values to avoid large values from becoming negative values.

         - improve support for the MIPS GIC timer.

         - enable common clock framework for Malta and SEAD3.

         - a number of improvments and fixes to dump_tlb().

         - document the MIPS TLB dump functionality in Magic SysRq.

         - Cavium Octeon CN68XX improvments.

         - NetLogic improvments.

         - irq: Use access helper irq_data_get_affinity_mask.

         - handle MSA unaligned accesses.

         - a number of R6-related math-emu fixes.

         - support for I6400.

         - improvments to MSA support.

         - add uprobes support.

         - move from deprecated __initcall to arch_initcall.

         - remove finish_arch_switch().

         - IRQ cleanups by Thomas Gleixner.

         - migrate to new 'set-state' interface.

         - random small cleanups"

      Pull locking and atomic updates from Ingo Molnar:
       "Main changes in this cycle are:

         - Extend atomic primitives with coherent logic op primitives
           (atomic_{or,and,xor}()) and deprecate the old partial APIs
           (atomic_{set,clear}_mask())

           The old ops were incoherent with incompatible signatures across
           architectures and with incomplete support.  Now every architecture
           supports the primitives consistently (by Peter Zijlstra)

         - Generic support for 'relaxed atomics':

             - _acquire/release/relaxed() flavours of xchg(), cmpxchg() and 
{add,sub}_return()
             - atomic_read_acquire()
             - atomic_set_release()

           This came out of porting qwrlock code to arm64 (by Will Deacon)

         - Clean up the fragile static_key APIs that were causing repeat bugs,
           by introducing a new one:

             DEFINE_STATIC_KEY_TRUE(name);
             DEFINE_STATIC_KEY_FALSE(name);

           which define a key of different types with an initial true/false
           value.

           Then allow:

             static_branch_likely()
             static_branch_unlikely()

           to take a key of either type and emit the right instruction for the
           case.  To be able to know the 'type' of the static key we encode it
           in the jump entry (by Peter Zijlstra)

      ====================
      couple of sctp fixes for 0ca50d12fe46

      These are two fixes for sctp after my patch on 0ca50d12fe46 ("sctp: fix
      src address selection if using secondary addresses")

      The first, fix a dst leak on those it decided to skip.

      The second, adds the fallback on src selection that Vlad had asked
      about. Unfortunatelly a lot of ipvs setups relies on the old behavior
      and I don't see a better fix for it.

      Please consider both to -stable tree.

      sctp: add routing output fallback

      Commit 0ca50d12fe46 added a restriction that the address must belong to
      the output interface, so that sctp will use the right interface even
      when using secondary addresses.

      But it breaks IPVS setups, on which people is used to attach VIP
      addresses to loopback interface on real servers. It's preferred to
      attach to the interface actually in use, but it's a very common setup
      and that used to work.

      This patch then saves the first routing good result, even if it would be
      going out through an interface that doesn't have that address. If no
      better hit found, it's then used. This effectively restores the original
      behavior if no better interface could be found.

      net: eth: altera: fix napi poll_list corruption

      tse_poll() calls __napi_complete() with irq enabled.  This leads napi
      poll_list corruption and may stop all napi drivers working.
      Use napi_complete() instead of __napi_complete().

      IB/ipoib: Suppress warning for send only join failures

      We expect send only joins to fail, it just means there are no listeners
      for the group. The correct thing to do is silently drop the packet
      at source.

      Eg avahi will full join 224.0.0.251 which causes a send only IGMP packet
      to 224.0.0.22, and then a warning level kmessage like this:

       ib0: sendonly multicast join failed for 
ff12:401b:ffff:0000:0000:0000:0000:0016, status -22

      ipmi: Don't call receive handler in the panic context

      Received handlers defined as ipmi_recv_hndl member of struct
      ipmi_user_hndl can take a spinlock.  This means that if the kernel
      panics while holding the lock, a deadlock may happen on the lock
      while flushing queued messages in the panic context.

      Calling the receive handler doesn't make much meanings in the panic
      context, simply skip it to avoid possible deadlocks.

      ipmi: Avoid touching possible corrupted lists in the panic context

      When processing queued messages in the panic context, IPMI driver
      tries to do it without any locking to avoid deadlocks.  However,
      this means we can touch a corrupted list if the kernel panicked
      while manipulating the list.  Fortunately, current `add-tail and
      del-from-head' style implementation won't touch the corrupted part,
      but it is inherently risky.

      To get rid of the risk, this patch re-initializes the message lists
      on panic if the related spinlock has already been acquired.  As the
      result, we may lose queued messages, but it's not so painful.
      Dropping messages on the received message list is also less
      problematic because no one can respond the received messages.

      ipmi: Don't flush messages in sender() in run-to-completion mode

      When flushing queued messages in run-to-completion mode,
      smi_event_handler() is recursively called.

      flush_messages()
       smi_event_handler()
        handle_transaction_done()
         deliver_recv_msg()
          ipmi_smi_msg_received()
           smi_recv_tasklet()
            sender()
             flush_messages()
              smi_event_handler()
               ...

      The depth of the recursive call depends on the number of queued
      messages, so it can cause a stack overflow if many messages have
      been queued.

      To solve this problem, this patch removes flush_messages()
      from sender()@ipmi_si_intf.c.  Instead, add flush_messages() to
      caller side of sender() if needed.  Additionally, to implement this,
      add new handler flush_messages to struct ipmi_smi_handlers.

      ipmi: Convert the IPMI SI ACPI handling to a platform device

      The IPMI SI driver was using direct PNP, but that was not really
      ideal because the IPMI device is a platform device.  There was
      some special handling in the acpi_pnp.c code for making this work,
      but that was breaking ACPI handling for the IPMI SSIF driver.

      So without this patch there were significant issues getting the
      SSIF driver to work with ACPI.

      So use a platform device for ACPI detection and remove the
      entry from acpi_pnp.c.

      IB/srp: Fix possible protection fault

      srp_destroy_qp is designed to indicate we are safe to continue with
      freeing the channel resources by modifying the qp error state,
      posting a dummy wr on the queue-pair and waiting for it to flush.
      This also holds for the channel registration pool as we are unmapping
      the memory region when handling a scsi response. Destroying the
      channel registration pool before we make sure we processed all the
      inflight IO might introduce a use-after-free of the registration pool.

      This use-after-free is demonstrated in the stack trace below where
      srp is trying to unmap a used FMR after the fmr_pool was already 
destroyed.

       "The biggest change in the pull is the removal of ext3 filesystem
        driver (~28k lines removed).  Ext4 driver is a full featured
        replacement these days and both RH and SUSE use it for several years

        mainly for ext3 which we could eventually get rid of.

        Other larger change is addition of proper error handling for
        dquot_initialize().  The rest is small fixes and cleanups"

      [ I wasn't convinced about the ext3 removal and worried about things
        falling through the cracks for legacy users, but ext4 maintainers
        piped up and were all unanimously in favor of removal, and maintaining

      optimize_nops() is buggy in two aspects:

      mlx5: Fix incorrect wc pkey_index assignment for GSI messages

      Since patch series "Demux IB CM requests in the rdma_cm module" the
      P_Key index is taken from the work completion rather than the message
      itself.

      The HCA provides us with the message P_Key. In order to provide the
      P_Key index, we need to look it up. Given that this is relevant only
      for GSI messages (session establishments) which is less performance 
critical,
      micro-optimize against the GSI (is_qp1) branch.

      Input: elan_i2c - use iap_version to get firmware information

      When driver is in IAP mode ic_type query may return 0xff. However
      iap_version will always be valid, so let's use it to determine parameters
      of the firmware that the controller is supposed to accept.

      [media] cx231xx: Use wake_up_interruptible() instead of 
wake_up_interruptible_nr()

      While looking at use cases of the wake queues in order to add support
      for simple wait queues, I noticed that there was only a single user of
      wake_up_interruptible_nr(), and that use was doing a single task wake
      up. Have that user use the proper wake_up_interruptible() instead, and
      perhaps we can even remove the function wake_up_interruptible_nr().

       "Another merge window, another set of networking changes.  I've heard
        rumblings that the lightweight tunnels infrastructure has been voted
        networking change of the year.  But what do I know?

         1) Add conntrack support to openvswitch, from Joe Stringer.

         2) Initial support for VRF (Virtual Routing and Forwarding), which
            allows the segmentation of routing paths without using multiple
            devices.  There are some semantic kinks to work out still, but
            this is a reasonably strong foundation.  From David Ahern.

         3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov.

         4) Ignore route nexthops with a link down state in ipv6, just like
            ipv4.  From Andy Gospodarek.

         5) Remove spinlock from fast path of act_gact and act_mirred, from
            Eric Dumazet.

         6) Document the DSA layer, from Florian Fainelli.

         7) Add netconsole support to bcmgenet, systemport, and DSA.  Also
            from Florian Fainelli.

         8) Add Mellanox Switch Driver and core infrastructure, from Jiri
            Pirko.

         9) Add support for "light weight tunnels", which allow for
            encapsulation and decapsulation without bearing the overhead of a
            full blown netdevice.  From Thomas Graf, Jiri Benc, and a cast of
            others.

        10) Add Identifier Locator Addressing support for ipv6, from Tom
            Herbert.

        11) Support fragmented SKBs in iwlwifi, from Johannes Berg.

        12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia.

        13) Add BQL support to 3c59x driver, from Loganaden Velvindron.

        14) Stop using a zero TX queue length to mean that a device shouldn't
            have a qdisc attached, use an explicit flag instead.  From Phil
            Sutter.

        15) Use generic geneve netdevice infrastructure in openvswitch, from
            Pravin B Shelar.

        16) Add infrastructure to avoid re-forwarding a packet in software
            that was already forwarded by a hardware switch.  From Scott
            Feldman.

        17) Allow AF_PACKET fanout function to be implemented in a bpf
            program, from Willem de Bruijn"

      ring-buffer: Revert "ring-buffer: Get timestamp after event is allocated"

      The commit a4543a2fa9ef31 "ring-buffer: Get timestamp after event is
      allocated" is needed for some future work. But after adding it, there is a
      race somewhere that causes the saved timestamp to have a slight shift, and
      get ahead of the actual timestamp and make it look like time goes 
backwards.

      I'm still looking into why this happens, but in the mean time, this is
      holding up other work to get in. I'm reverting the change for now (which
      makes the problem go away), and will add it back after I know what is 
wrong
      and fix it.

  commit e0d8b2ec532852d4b5aabcec3e7611848c32237d
  Author: Yousong Zhou <yszhou4tech@xxxxxxxxx>

      MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.

      The nomips16 has to be added both as function attribute and assembler
      directive.

      When only function attribute is specified, the compiler will inline the
      function with -Os optimization.  The generated assembly code cannot be
      correctly assembled because ISA mode switch has to be done through jump
      instruction.

      When only ".set nomips16" directive is used, the generated assembly code
      will use MIPS32 code for the inline assembly template and MIPS16 for the
      function return.  The compiled binary is invalid:

          00403100 <__arch_swab16>:
            403100:   7c0410a0    wsbh    v0,a0
            403104:   e820ea31    swc2    $0,-5583(at)

      while correct code should be:

          00402650 <__arch_swab16>:
            402650:   7c0410a0    wsbh    v0,a0
            402654:   03e00008    jr  ra
            402658:   3042ffff    andi    v0,v0,0xffff

      The functionality of the new CMP.condn.fmt is the following one:

      If the comparison specified by the condn field of the instruction
      is true for the operand values, the result is true; otherwise, the
      result is false. If no exception is taken, the result is written into
      FPR fd; true is all 1s and false is all 0s repeated the operand width
      of fmt. All other bits beyond the operand width fmt are UNPREDICTABLE.

      CLOCKSOURCE: Add Pistachio clocksource-only driver

      The Pistachio SoC provides four general purpose timers, and allow
      to implement a clocksource driver.

      This driver can be used as a replacement for the MIPS GIC and MIPS R4K
      clocksources and sched clocks, which are clocked from the CPU clock.

      Given the general purpose timers are clocked from an independent clock,
      this new clocksource driver will be useful to introduce CPUFreq support
      for Pistachio machines.

      MIPS: Tidy up FPU context switching

      Rather than saving the scalar FP or vector context in the assembly
      resume function, reuse the existing C code we have in fpu.h to do
      exactly that. This reduces duplication, results in a much easier to read
      resume function & should allow the compiler to optimise out more MSA
      code due to is_msa_enabled()/cpu_has_msa being known-zero at compile
      time for kernels without MSA support.

      MIPS: Netlogic: Use chip_data for irq_chip methods

      Update mips/netlogic/common/irq.c and mips/pci/msi-xlp.c to use chip_data
      to store interrupt controller data pointer. It uses handler_data now,
      and that causes errors when an API (like the GPIO subsystem) tries to
      use the handler data.

      MIPS: Remove all the uses of custom gpio.h

      Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
      machines, and each machine type provides its own gpio.h. However
      only a handful really implement the GPIO API, most just forward
      everythings to gpiolib.

      The Alchemy machine is notable as it provides a system to allow
      implementing the GPIO API at the board level. But it is not used by
      any board currently supported, so it can also be removed.

      For most machine types we can just remove the custom gpio.h, as well
      as the custom wrappers if some exists. Some of the code found in
      the wrappers must be moved to the respective GPIO driver.

      A few more fixes are need in some drivers as they rely on linux/gpio.h
      to provides some machine specific definitions, or used asm/gpio.h
      instead of linux/gpio.h for the gpio API.

      MIPS: Add implementation of dma_map_ops.mmap()

      The generic implementation of dma_map_ops.mmap(), dma_common_mmap(),
      is not correct for non-coherent devices. It expects to be passed a
      virtual address previously returned by dma_alloc_coherent(), which for
      a non-coherent device will return a KSEG1 address. It then attempts to
      convert that virtual address to a physical address using virt_to_page()
      which will yield an incorrect address.

      Also, dma_common_mmap() does not handle the DMA_ATTR_WRITE_COMBINE
      attribute, and therefore dma_mmap_writecombine() will not actually set
      the appropriate pgprot_t flags for write combining.

      This patch adds an implementation of dma_map_ops.mmap() that correctly
      handles KSEG1 addresses, and enables write combining when requested.

      MIPS: AT_HWCAP aux vector infrastructure

      In order for userland to determine whether various features are safe to
      use, it will need to know both that the hardware supports those features
      and that the kernel is recent enough & configured appropriately to
      support them. For example under the O32 modeless FP proposal the dynamic
      linker & ifunc resolvers will need this information.  The kernel is the
      only thing in a position to know availability accurately, so the kernel
      needs to provide the information to userland. This patch introduces the
      infrastructure to provide the AT_HWCAP aux vector to userland in order
      to provide that information. It also defines the 2 currently specified
      flags, which indicate MIPSr6 & MSA support.

      MIPS: Save MSA extended context around signals

      It is desirable for signal handlers to be allowed to make use of MSA,
      particularly if auto vectorisation is used when compiling a program.
      The MSA context must therefore be saved & restored before & after
      invoking the signal handler. Make use of the extended context structs
      defined in the preceding patch to save MSA context after the sigframe
      when appropriate.

      MIPS: Add definitions for extended context

      The context introduced by MSA needs to be saved around signals. However,
      we can't increase the size of struct sigcontext because that will change
      the offset of the signal mask in struct sigframe or struct ucontext.
      This patch instead places the new context immediately after the struct
      sigframe for traditional signals, or similarly after struct ucontext for
      RT signals. The layout of struct sigframe & struct ucontext is identical
      from their sigcontext fields onwards, so the offset from the sigcontext
      to the extended context will always be the same regardless of the type
      of signal.

      Userland will be able to search through the extended context by using
      the magic values to detect which types of context are present. Any
      unrecognised context can be skipped over using the size field of struct
      extcontext. Once the magic value END_EXTCONTEXT_MAGIC is seen it is
      known that there are no further extended context structures to examine.

      This approach is somewhat similar to that taken by ARM to save VFP &
      other context at the end of struct ucontext.

      Userland can determine whether extended context is present by checking
      for the USED_EXTCONTEXT bit in the sc_used_math field of struct
      sigcontext. Whilst this could potentially change the historic semantics
      of sc_used_math if further extended context which does not imply FP
      context were to be introduced in the future, I have been unable to find
      any userland code making use of sc_used_math at all. Using one of the
      fields described as unused in struct sigcontext was considered, but the
      kernel does not already write to those fields so there would be no
      guarantee of the field being clear on older kernels. Other alternatives
      would be to have userland check the kernel version, or to have a HWCAP
      bit indicating presence of extended context. However there is a desire
      to have the context & information required to decode it be self
      contained such that, for example, debuggers could decode the saved
      context easily.

      MIPS: Indicate FP mode in sigcontext sc_used_math

      The sc_used_math field of struct sigcontext & its variants has
      traditionally been used as a boolean value indicating only whether or
      not floating point context is saved within the sigcontext. With various
      supported FP modes & the ability to switch between them this information
      will no longer be enough to decode the meaning of the data stored in the
      sc_fpregs fields of struct sigcontext.

      To make that possible 3 bits are defined within sc_used_math:

        - Bit 0 (USED_FP) represents whether FP was used, essentially
          providing the boolean flag which sc_used_math as a whole provided
          previously.

        - Bit 1 (USED_FR1) provides the value of the Status.FR bit at the time
          the FP context was saved.

        - Bit 2 (USED_HYBRID_FPRS) indicates whether the FP context was saved
          under the hybrid FPR scheme. Essentially, when set the odd singles
          are located in bits 63:32 of the preceding even indexed sc_fpregs
          element.

      Any userland that tests whether the sc_used_math field is zero or
      non-zero will continue to function as expected. Having said that, I
      could not find any userland which uses the sc_used_math field at all.

      MIPS: Skip odd double FP registers when copying FP32 sigcontext

      When a task uses 32 bit floating point, the odd indexed 32b register
      values are stored in bits 63:32 of the preceding even indexed 64b
      FP register field in saved context. Thus there is no point in
      preserving the odd indexed 64b register fields since they hold no
      valid context. This patch will cause them to be skipped, as is
      already done in arch/mips/kernel/signal32.c.

      MIPS: Refactor dumping of TLB registers for r3k/r4k

      The TLB registers are dumped in a couble of places:
       - sysrq_tlbdump_single() - when dumping TLB state.
       - do_mcheck() - in response to a machine check error.

      The main TLB registers also differ between r3k and r4k, but r4k appears
      to be assumed.

      Refactor this code into a dump_tlb_regs() function, implemented for both
      r3k and r4k, and used by both of the above functions.

      MIPS: Use unsigned int when reading CP0 registers

      Update __read_32bit_c0_register() and __read_32bit_c0_ctrl_register() to
      use "unsigned int res;" instead of "int res;". There is little reason to
      treat these register values as signed. They are either counters (which
      by definition are unsigned) or are made up of various bit fields to be
      interpreted as per the CPU datasheet.

      This has come up via u-boot[1] which sync's asm/mipsregs.h with the
      kernel. In u-boots case the value read from read_c0_count() is assigned
      to an unsigned long [2] which triggers a sign extension and causes a
      bug.

      U-boot should probably be more explicit about the types used for the
      timer_read_counter() API but that aside is there any reason to treat
      these values as signed integers? A quick grep around the arch/mips makes
      me thing that there may be some bugs lurking when read_c0_count() starts
      to yield a negative value but I haven't really explored any of them.

      MIPS: MSA unaligned memory access support

      The MSA architecture specification allows for hardware to not implement
      unaligned vector memory accesses in some or all cases. A typical example
      of this is the I6400 core which does not implement unaligned vector
      memory access when the memory crosses a page boundary. The architecture
      also requires that such memory accesses complete successfully as far as
      userland is concerned, so the kernel is required to emulate them.

      This patch implements support for emulating unaligned MSA ld & st
      instructions by copying between the user memory & the tasks FP context
      in struct thread_struct, updating hardware registers from there as
      appropriate in order to avoid saving & restoring the entire vector
      context for each unaligned memory access.

      Tested both using an I6400 CPU and with a QEMU build hacked to produce
      AdEL exceptions for unaligned vector memory accesses.

      [paul.burton@xxxxxxxxxx:
        - Remove #ifdef's
        - Move msa_op into enum major_op rather than #define
        - Replace msa_{to,from}_wd with {read,write}_msa_wr_{b,h,w,l} and the
          format-agnostic wrappers, removing the custom endian mangling for
          big endian systems.
        - Restructure the msa_op case in emulate_load_store_insn to share
          more code between the load & store cases.
        - Avoid the need for a temporary union fpureg on the stack by simply
          reusing the already suitably aligned context in struct
          thread_struct.
        - Use sizeof(*fpr) rather than hardcoding 16 as the size for user
          memory checks & copies.
        - Stop recalculating the address of the unaligned vector memory access
          and rely upon the value read from BadVAddr as we do for other
          unaligned memory access instructions.
        - Drop the now unused val8 & val16 fields in union fpureg.
        - Rewrite commit message.
        - General formatting cleanups.]

      MIPS: Remove "weak" from mips_cdmm_phys_base() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
      decl")).

      mips_cdmm_phys_base() is defined only in 
arch/mips/mti-malta/malta-memory.c
      so there's no problem with multiple definitions.  But it works better to
      have a weak default implementation and allow a strong function to override
      it.  Then we don't have to test whether a definition is present, and if
      there are ever multiple strong definitions, we get a link error instead of
      calling a random definition.

      Add a weak mips_cdmm_phys_base() definition and remove the weak annotation
      from the declaration in arch/mips/include/asm/cdmm.h.

      MIPS: Remove "weak" from get_c0_compare_int() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node

      get_c0_compare_int() is defined in several files.  Each definition is 
weak,
      so I assume Kconfig prevents two or more from being included.  The caller
      contains default code used when get_c0_compare_int() isn't defined at all.

      Add a weak get_c0_compare_int() definition with the default code and 
remove
      the weak annotation from the declaration.

      Then the platform implementations will be strong and will override the 
weak
      default.  If multiple platforms are ever configured in, we'll get a link
      error instead of calling a random platform's implementation.

      KVM: PPC: Book3S: Fix size of the PSPB register

      The size of the Problem State Priority Boost Register is only
      32 bits, but the kvm_vcpu_arch->pspb variable is declared as
      "ulong", ie. 64-bit. However, the assembler code accesses this
      variable with 32-bit accesses, and the KVM_REG_PPC_PSPB macro
      is defined with SIZE_U32, too, so that the current code is
      broken on big endian hosts: kvmppc_get_one_reg_hv() will only
      return zero for this register since it is using the wrong half
      of the pspb variable. Let's fix this problem by adjusting the
      size of the pspb field in the kvm_vcpu_arch structure.

      KVM: PPC: Book3S HV: Exit on H_DOORBELL if HOST_IPI is set

      The code that handles the case when we receive a H_DOORBELL interrupt
      has a comment which says "Hypervisor doorbell - exit only if host IPI
      flag set".  However, the current code does not actually check if the
      host IPI flag is set.  This is due to a comparison instruction that
      got missed.

      As a result, the current code performs the exit to host only
      if some sibling thread or a sibling sub-core is exiting to the
      host.  This implies that, an IPI sent to a sibling core in
      (subcores-per-core != 1) mode will be missed by the host unless the
      sibling core is on the exit path to the host.

      This patch adds the missing comparison operation which will ensure
      that when HOST_IPI flag is set, we unconditionally exit to the host.

      KVM: PPC: Book3S HV: Fix race in starting secondary threads

      The current dynamic micro-threading code has a race due to which a
      secondary thread naps when it is supposed to be running a vcpu. As a
      side effect of this, on a guest exit, the primary thread in
      kvmppc_wait_for_nap() finds that this secondary thread hasn't cleared
      its vcore pointer. This results in "CPU X seems to be stuck!"
      warnings.

      The race is possible since the primary thread on exiting the guests
      only waits for all the secondaries to clear its vcore pointer. It
      subsequently expects the secondary threads to enter nap while it
      unsplits the core. A secondary thread which hasn't yet entered the nap
      will loop in kvm_no_guest until its vcore pointer and the do_nap flag
      are unset. Once the core has been unsplit, a new vcpu thread can grab
      the core and set the do_nap flag *before* setting the vcore pointers
      of the secondary. As a result, the secondary thread will now enter nap
      via kvm_unsplit_nap instead of running the guest vcpu.

      Fix this by setting the do_nap flag after setting the vcore pointer in
      the PACA of the secondary in kvmppc_run_core. Also, ensure that a
      secondary thread doesn't nap in kvm_unsplit_nap when the vcore pointer
      in its PACA struct is set.

       - a 4.2-stable fix that adds feature reporting for the dm-stats
         features added in 4.2

       - improve DM-snapshot to not invalidate the on-disk snapshot if
         snapshot device write overflow occurs; but a write overflow triggered
         through the origin device will still invalidate the snapshot.

       - optimize DM-thinp's async discard submission a bit now that late bio
         splitting has been included in block core.

       - switch DM-cache's SMQ policy lock from using a mutex to a spinlock;
         improves performance on very low latency devices (eg. NVMe SSD).

       - document DM RAID 4/5/6's discard support

      mtd: spi-nor: fix NULL dereference when no match found in spi_nor_ids[]

      Commit 06bb6f5a69df ("mtd: spi-nor: stop (ab)using struct
      spi_device_id") converted an array into a pointer, which means that
      we should be checking if the pointer goes anywhere, not whether the C
      string is empty. To do the latter means we dereference a NULL pointer
      when we reach the terminating entry, for which 'name' is now NULL
      instead of an array { 0, 0, ... }.

      Sample crash:

      netfilter: nf_conntrack: make nf_ct_zone_dflt built-in

      Fengguang reported, that some randconfig generated the following linker
      issue with nf_ct_zone_dflt object involved:

        [...]
        CC      init/version.o
        LD      init/built-in.o
        net/built-in.o: In function `ipv4_conntrack_defrag':

        nf_defrag_ipv6_hooks.c:(.text+0xe3ffe): undefined reference to 
`nf_ct_zone_dflt'
        make: *** [vmlinux] Error 1

      Given that configurations exist where we have a built-in part, which is
      accessing nf_ct_zone_dflt such as the two handlers nf_ct_defrag_user()
      and nf_ct6_defrag_user(), and a part that configures nf_conntrack as a
      module, we must move nf_ct_zone_dflt into a fixed, guaranteed built-in
      area when netfilter is configured in general.

      Therefore, split the more generic parts into a common header under
      include/linux/netfilter/ and move nf_ct_zone_dflt into the built-in
      section that already holds parts related to CONFIG_NF_CONNTRACK in the
      netfilter core. This fixes the issue on my side.

      net: fec: clear receive interrupts before processing a packet

      The patch just to re-submit the patch "db3421c114cfa6326" because the
      patch "4d494cdc92b3b9a0" remove the change.

      Clear any pending receive interrupt before we process a pending packet.
      This helps to avoid any spurious interrupts being raised after we have
      fully cleaned the receive ring, while still allowing an interrupt to be
      raised if we receive another packet.

      The position of this is critical: we must do this prior to reading the
      next packet status to avoid potentially dropping an interrupt when a
      packet is still pending.

      null_blk: fix wrong capacity when bs is not 512 bytes

      set_capacity() sets device's capacity using 512 bytes sectors.
      null_blk calculates the number of sectors by size / bs, which
      set_capacity is called with. This led to null_blk exposing the
      wrong number of sectors when bs is not 512 bytes.

      We previously register IPPROTO_ROUTING offload under inet6_add_offload(),

      doesn't seem correct, it should actually be inet6_del_offload(), also

      perf tools: Fix use of wrong event when processing exit events

      In a couple of cases the 'comm' member of 'union event' has been used
      instead of the correct member ('fork') when processing exit events.

      In the cases where it has been used incorrectly, only the 'pid' and
      'tid' are affected.  The 'pid' value would be correct anyway because it
      is in the same position in 'comm' and 'fork' events, but the 'tid' would
      have been incorrectly assigned from 'ppid'.

      However, for exit events, the kernel puts the current task in the 'ppid'
      and 'ttid' which is the same as the exiting task.  That is 'ppid' ==
      'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the
      data goes wrong only when tracing multi-threaded programs.

      It is hard to find an example of how this would produce an error in
      practice.  There are 3 occurences of the fix:

      1. perf script is only affected if !sample_id_all which only happens on
        old kernels.

      2. intel_pt is only affected when decoding without timestamps
         and would probably still decode correctly - the exit event is
         only used to flush out data which anyway gets flushed at the
         end of the session

      3. intel_bts also uses the exit event to flush data which
         would probably not cause errors as it would get flushed at
         the end of the session instead

      Pull core block updates from Jens Axboe:
       "This first core part of the block IO changes contains:

         - Cleanup of the bio IO error signaling from Christoph.  We used to
           rely on the uptodate bit and passing around of an error, now we
           store the error in the bio itself.

         - Improvement of the above from myself, by shrinking the bio size
           down again to fit in two cachelines on x86-64.

         - Revert of the max_hw_sectors cap removal from a revision again,
           from Jeff Moyer.  This caused performance regressions in various
           tests.  Reinstate the limit, bump it to a more reasonable size
           instead.

         - Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.
           Most devices have huge trim limits, which can cause nasty latencies
           when deleting files.  Enable the admin to configure the size down.
           We will look into having a more sane default instead of UINT_MAX
           sectors.

         - Improvement of the SGP gaps logic from Keith Busch.

         - Enable the block core to handle arbitrarily sized bios, which
           enables a nice simplification of bio_add_page() (which is an IO hot
           path).  From Kent.

         - Improvements to the partition io stats accounting, making it
           faster.  From Ming Lei.

         - Also from Ming Lei, a basic fixup for overflow of the sysfs pending
           file in blk-mq, as well as a fix for a blk-mq timeout race
           condition.

         - Ming Lin has been carrying Kents above mentioned patches forward
           for a while, and testing them.  Ming also did a few fixes around
           that.

         - Sasha Levin found and fixed a use-after-free problem introduced by
           the bio->bi_error changes from Christoph.

         - Small blk cgroup cleanup from Viresh Kumar"

      xen-netback: add support for multicast control

      Xen's PV network protocol includes messages to add/remove ethernet
      multicast addresses to/from a filter list in the backend. This allows
      the frontend to request the backend only forward multicast packets
      which are of interest thus preventing unnecessary noise on the shared
      ring.

      The canonical netif header in git://xenbits.xen.org/xen.git specifies
      the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal
      necessary changes have been pulled into include/xen/interface/io/netif.h.

      To prevent the frontend from extending the multicast filter list
      arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries.
      This limit is not specified by the protocol and so may change in future.
      If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD
      sent by the frontend will be failed with NETIF_RSP_ERROR.

      sock, diag: fix panic in sock_diag_put_filterinfo

      diag socket's sock_diag_put_filterinfo() dumps classic BPF programs
      upon request to user space (ss -0 -b). However, native eBPF programs
      attached to sockets (SO_ATTACH_BPF) cannot be dumped with this method:

      Their orig_prog is always NULL. However, sock_diag_put_filterinfo()
      unconditionally tries to access its filter length resp. wants to copy
      the filter insns from there. Internal cBPF to eBPF transformations
      attached to sockets don't have this issue, as orig_prog state is kept.

      It's currently only used by packet sockets. If we would want to add
      native eBPF support in the future, this needs to be done through
      a different attribute than PACKET_DIAG_FILTER to not confuse possible
      user space disassemblers that work on diag data.

sockets")

      drm/exynos: remove buf_cnt from struct exynos_drm_fb

      Looking other drm drivers, there is no the restriction that framebuffer
      has only one buffer in .create_handle() callback. They use just first
      buffer.

      If this limitation is removed, there is no reason keeping buffer count
      for framebuffer, so we can remove buf_cnt from struct exynos_drm_fb.

      The correct check is to compute the position of the

      the delegation. While this does not completely eliminate the sending

      drm/i915: Always mark the object as dirty when used by the GPU

      There have been many hard to track down bugs whereby userspace forgot to
      flag a write buffer and then cause graphics corruption or a hung GPU
      when that buffer was later purged under memory pressure (as the buffer
      appeared clean, its pages would have been evicted rather than preserved
      and any changes more recent than in the backing storage would be lost).
      In retrospect this is a rare optimisation against memory pressure,
      already the slow path. If we always mark the buffer as dirty when
      accessed by the GPU, anything not used can still be evicted cheaply
      (ideal behaviour for mark-and-sweep eviction) but we do not run the risk
      of corruption. For correct read serialisation, userspace still has to
      notify when the GPU writes to an object. However, there are certain
      situations under which userspace may wish to tell white lies to the
      kernel...

      drm/dp: Adjust i2c-over-aux retry count based on message size and i2c bus 
speed

      Calculate the number of retries we should do for each i2c-over-aux
      message based on the time it takes to perform the i2c transfer vs. the
      aux transfer. We assume the shortest possible length for the aux
      transfer, and the longest possible (exluding clock stretching) for the
      i2c transfer.

      The DP spec has some examples on how to calculate this, but we don't
      calculate things quite the same way. The spec doesn't account for the
      retry interval (assumes immediate retry on defer), and doesn't assume
      the best/worst case behaviour as we do.

      Note that currently we assume 10 kHz speed for the i2c bus. Some real
      world devices (eg. some Apple DP->VGA dongle) fails with less than 16
      retries. and that would correspond to something close to 15 kHz (with
      our method of calculating things) But let's just go for 10 kHz to be
      on the safe side. Ideally we should query/set the i2c bus speed via
      DPCD but for now this should at leaast remove the regression from the
      1->16 byte trasnfer size change. And of course if the sink completes
      the transfer quicker this shouldn't slow things down since we don't
      change the interval between retries.

      I did a few experiments with a DP->DVI dongle I have that allows you
      to change the i2c bus speed. Here are the results of me changing the
      actual bus speed and the assumed bus speed and seeing when we start
      to fail the operation:

      actual i2c khz          assumed i2c khz         max retries
      1                       1 ok -> 2 fail          211 ok -> 106 fail
      5                       8 ok -> 9 fail          27 ok -> 24 fail
      10                      17 ok -> 18 fail        13 ok -> 12 fail
      100                     210 ok -> 211 fail      2 ok -> 1 fail

      So based on that we have a fairly decent safety margin baked into
      the formula to calculate the max number of retries.

      drm/dp: Define AUX_RETRY_INTERVAL as 500 us

      Currently we react to native and i2c defers by waiting either 400-500 us
      or 500-600 us, depending on which code path we take. Consolidate them
      all to one define AUX_RETRY_INTERVAL which defines the minimum interval.
      Since we've been using two different intervals pick the longer of them
      and define AUX_RETRY_INTERVAL as 500 us. For the maximum just use
      AUX_RETRY_INTERVAL+100 us.

      I want to have a define for this so that I can use it when calculating
      the estimated duration of i2c-over-aux transfers. Without a define it
      would be very easy to change the sleep duration and neglect to update
      the i2c-over-aux estimates.

      spi: spi-pxa2xx: Check status register to determine if SSSR_TINT is 
disabled

      On Intel Baytrail, there is case when interrupt handler get called, no SPI
      message is captured. The RX FIFO is indeed empty when RX timeout pending
      interrupt (SSSR_TINT) happens.

      Use the BIOS version where both HSUART and SPI are on the same IRQ. Both
      drivers are using IRQF_SHARED when calling the request_irq function. When
      running two separate and independent SPI and HSUART application that
      generate data traffic on both components, user will see messages like
      below on the console:

        pxa2xx-spi pxa2xx-spi.0: bad message state in interrupt handler

      This commit will fix this by first checking Receiver Time-out Interrupt,
      if it is disabled, ignore the request and return without servicing.

      nohz: Assert existing housekeepers when nohz full enabled

      The code ensures that when nohz full is running, at least the
      boot CPU serves as a housekeeper and it can't be later offlined.

      Let's assert this assumption to make sure that we have CPUs to
      handle unbound jobs like workqueues and timers while nohz full
      CPUs run undisturbed.

      Also improve the comments on housekeeper offlining prevention.

      This patch will affine timers to online CPUs which are not full
      dynticks in NOHZ_FULL configured systems. It should not
      introduce overhead in nohz full off case due to static keys.

      x86/mm/srat: Print non-volatile flag in SRAT

      With the addition of NVDIMM support, a question came up as to
      whether NVDIMM ranges should be in the SRAT with this bit set.
      I think the consensus was no because the ranges are in the NFIT
      with proximity domain information there.

      ACPI is not clear on the meaning of this bit in the SRAT.
      If someone is setting it, we might want to ask them what they
      expect to happen with it.

      Right now this bit is only printed if all the ACPI debug
      information is turned on.

      Intel Wired LAN Driver Updates 2015-09-01

      This series contains updates to i40e, ixgbe and ixgbevf.

      Anjali fixes a bug in i40e where the port is not receiving multicast or 
VLAN
      tagged packets in promiscuous mode.  Which can occur when a software 
bridge
      is created on top of the device.

      Don adds support in ixgbe that indicates the presence of management 
firmware.
      Added support for entering low power link up state on devices that support
      it when the device is closing or suspending.  Updated the driver to report
      unknown bus speed and width since IOSF does not report a PCIe bus speed or
      width for X550 devices.  Also added the new bus type for integrated I/O
      interface (IOSF).  Cleaned up of redundant code in ixgbe.

      Mark adds support for UDP-encapsulation transmit checksum and for VXLAN
      receive offloads.  Introduces a helper function to do the register access
      and processing to avoid needless PHY access on copper PHYs.  Added support
      for reporting 2.5G link speed.  Fixed warnings resulting from redundant
      initializations of the get_bus_info field.

      Maninder Singh updates the ixgbe driver to use kzalloc instead of kcalloc
      for allocation of one thing.

      Tom Barbette adds support for ethtool to change the rxfh indirection table
      and/or key using ethtool interface.

      Emil resolves an issue where users were not able to dynamically set number
      of queues for 82598 via ethtool -L.

      Alex Williamson removes bimodal SR-IOV disabling behavior since it is
      confusing to users and results in a state where the PF is broken for other
      uses unless the user sets sriov_numvfs to zero prior to unbinding the
      device.

      Pull power management and ACPI updates from Rafael Wysocki:
       "From the number of commits perspective, the biggest items are ACPICA
        and cpufreq changes with the latter taking the lead (over 50 commits).

        On the cpufreq front, there are many cleanups and minor fixes in the
        core and governors, driver updates etc.  We also have a new cpufreq
        driver for Mediatek MT8173 chips.

        ACPICA mostly updates its debug infrastructure and adds a number of
        fixes and cleanups for a good measure.

        The Operating Performance Points (OPP) framework is updated with new
        DT bindings and support for them among other things.

        We have a few updates of the generic power domains framework and a
        reorganization of the ACPI device enumeration code and bus type
        operations.

        And a lot of fixes and cleanups all over.

        Included is one branch from the MFD tree as it contains some
        PM-related driver core and ACPI PM changes a few other commits are
        based on.

        Specifics:

         - ACPICA update to upstream revision 20150818 including method
           tracing extensions to allow more in-depth AML debugging in the
           kernel and a number of assorted fixes and cleanups (Bob Moore, Lv
           Zheng, Markus Elfring).

         - ACPI sysfs code updates and a documentation update related to AML
           method tracing (Lv Zheng).

         - ACPI EC driver fix related to serialized evaluations of _Qxx
           methods and ACPI tools updates allowing the EC userspace tool to be
           built from the kernel source (Lv Zheng).

         - ACPI processor driver updates preparing it for future introduction
           of CPPC support and ACPI PCC mailbox driver updates (Ashwin
           Chaugule).

         - ACPI interrupts enumeration fix for a regression related to the
           handling of IRQ attribute conflicts between MADT and the ACPI
           namespace (Jiang Liu).

         - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi
           Kasagar).

         - ACPI device registration code reorganization to separate the
           sysfs-related code and bus type operations from the rest (Rafael J
           Wysocki).

         - Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause,
           Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss).

         - ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan
           Xinhui, Rafael J Wysocki).

         - cpufreq core cleanups on top of the previous changes allowing it to
           preseve its sysfs directories over system suspend/resume (Viresh
           Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior).

         - cpufreq fixes and cleanups related to governors (Viresh Kumar).

         - cpufreq updates (core and the cpufreq-dt driver) related to the
           turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz).

         - New DT bindings for Operating Performance Points (OPP), support for
           them in the OPP framework and in the cpufreq-dt driver plus related
           OPP framework fixes and cleanups (Viresh Kumar).

         - cpufreq powernv driver updates (Shilpasri G Bhat).

         - New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen).

         - Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups
           and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean).

         - intel_pstate driver updates including Skylake-S support, support

      ixgbe: Remove bimodal SR-IOV disabling

      When unbinding an SR-IOV device with VFs configured from ixgbe, the
      driver behaves in one of two ways.  If max_vfs was specified, the
      SR-IOV state is disabled, removing the VFs.  The occurs regardless of
      whether the VF count was later modified through sysfs.  If however
      max_vfs is zero, such as by not specifying the module parameter, the
      VFs persist after the PF is unbound from ixgbe.  If the PF is then
      bound to vfio-pci to be assigned to a VM, the PF is non-functional.

      >From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV
      sysfs callback operation") clearly intended this alternate behavior,
      but probably didn't realize the PF doesn't work in this mode.

      This bimodal behavior is confusing to users and results in a state
      where the PF is broken for other uses unless the user sets
      sriov_numvfs to zero prior to unbinding the device.  Remove this
      behavior so that VFs are removed and the PF is functional for other
      uses after unbind, regardless of the way VFs are enabled.

      ixgbe: Remove second instance of lan_id variable

      This patch removes the redundant lan_id in the phy struct and uses
      the bus version.  Both variables exist and intend to represent the
      STATUS register LAN_ID field.  However, phy.lan_id is not bit shifted
      so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1.
      Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and
      bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional
      lan_id variable and this should make the code less confusing.

      i40e: Set defport behavior for the Main VSI when in promiscuous mode

      This fixes bugs where the port is not receiving multicast or VLAN tagged
      packets when in promiscuous mode. This can occur when a SW bridge is
      created on top of the device.

      This also fixes issues where the promiscuous behavior setting was not
      being preserved across a reset caused by features being enabled or
      disabled.

      We are using defport instead of doing a true promiscuous mode because we 
do
      not need to receive the SRIOV or VMDq VSI directed traffic which would 
suck
      up bandwidth and is really not intended for the SW bridge.

      In addition, with defport we get VLAN promiscuous behavior which is not
      possible from the VSI level promiscuous setting.

       "This finishes up the changes to ensure proc and sysfs do not start
        implementing executable files, as the there are application today that
        are only secure because such files do not exist.

        It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that
        did not show the proper source for files bind mounted from
        /proc/<pid>/ns/*.

        It also straightens out the handling of clone flags related to user
        namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER)
        when files such as /proc/<pid>/environ are read while <pid> is calling
        unshare.  This winds up fixing a minor bug in unshare flag handling
        that dates back to the first version of unshare in the kernel.

        Finally, this fixes a minor regression caused by the introduction of
        sysfs_create_mount_point, which broke someone's in house application,
        by restoring the size of /sys/fs/cgroup to 0 bytes.  Apparently that
        application uses the directory size to determine if a tmpfs is mounted
        on /sys/fs/cgroup.

        The bind mount escape fixes are present in Al Viros for-next branch.
        and I expect them to come from there.  The bind mount escape is the

      Tom Herbert says:

      ====================
      flow_dissector: Paramterize dissection and other features

      This patch set adds some new capabilities to flow_dissector:

      - Add flags to flow dissector functions to control dissection
        - Flag to stop dissection when L3 header is seen (don't
          dissect L4)
        - Flag to stop dissection when encapsulation is detected
        - Flag to parse first fragment of fragmented packet. This
          may provide L4 ports
      - Added new reporting in key_control
        - Packet is a fragment
        - Packet is a first fragment
        - Packet has encapsulation

      Also:
        - Make __skb_set_sw_hash a general function
        - Create functions to get a flow hash based on flowi4 or flowi6
          structures without an reference to an skbuff
        - Ignore flow dissector return value from ___skb_get_hash. Just
          use whatever key fields are found to make a hash

      Tested:

      Ran 200 netperf TCP_RR instances for IPv6 and IPv4. Did not see any
      regression. Ran UDP_RR with 10000 byte request and response size
      for IPv4 and IPv6, no regression observed however I did see better
      performance with IPv6 flow labels due to use of flow labels for L4
      hash.

      flow_dissector: Ignore flow dissector return value from ___skb_get_hash

      In ___skb_get_hash ignore return value from skb_flow_dissect_flow_keys.
      A failure in that function likely means that there was a parse error,
      so we may as well use whatever fields were found before the error was
      hit.  This is also good because it means we won't keep trying to derive
      the hash on subsequent calls to skb_get_hash for the same packet.

      flow_dissector: Add flag to stop parsing when an IPv6 flow label is seen

      Add an input flag to flow dissector on rather dissection should be
      stopped when a flow label is encountered. Presumably, the flow label
      is derived from a sufficient hash of an inner transport packet so
      further dissection is not needed (that is ports are not included in
      the flow hash). Using the flow label instead of ports has the additional
      benefit that packet fragments should hash to same value as non-fragments
      for a flow (assuming that the same flow label is used).

      We set this flag by default in for skb_get_hash.

      phylib: fix device deletion order in mdiobus_unregister()

      commit 8b63ec1837fa ("phylib: Make PHYs children of their MDIO bus, not
      the bus' parent.") uncovered a problem in mdiobus_unregister() which
      leads to this warning when I reboot an APM Mustang (arm64) platform:

      The problem is that mdiobus_unregister() deletes the bus device before
      unregistering the phy devices on the bus. This wasn't a problem before
      because the phys were not children of the bus:

        /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03
        /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0

      But now that they are:

        
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03

      when mdiobus_unregister deletes the bus device, the phy subdirs are
      removed from sysfs also. So when the phys are unregistered afterward,
      we get the warning. This patch changes the order so that phys are
      unregistered before the bus device is deleted.

the bus' parent.")

        hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
        UniPhier hardware!

        For those of you feeling less adventurous, added hardware support on

        of your liking.

        We've got something for everyone here!

      NFSv4.1/flexfiles: Fix freeing of mirrors

      Mirrors are now shared objects, so we should not be freeing them directly
      inside ff_layout_free_lseg(). We should already be doing the right thing
      in _ff_layout_free_lseg(), so just let it handle things.

      Also ensure that ff_layout_free_mirror() frees the RPC credential if it
      is set.

      nfsd: return CLID_INUSE for unexpected SETCLIENTID_CONFIRM case

      Somebody with a Solaris client was hitting this case.  We haven't
      figured out why yet, and don't have a reproducer.  Meanwhile Frank
      noticed that RFC 7530 actually recommends CLID_INUSE for this case.
      Unlikely to help the original reporter, but may as well fix it.

      irqchip/GIC: Fix EOImode setting for non-DT/ACPI systems

      Non-DT/ACPI systems call directly into the GIC driver at init time.
      Turns out 0b996fd35957 ("irqchip/GIC: Convert to EOImode == 1")
      breaks old non firmware-driven platforms, as the driver only
      works out the capability of the platform on the DT/ACPI paths.

      Fix this thinko by forcing EOImode==0 on non-DT platforms,
      which are not capable of supporting a hypervisor anyway.

      perf tools: Fix link time error with sample_reg_masks on non x86

      This patch makes perf compile on non x86 platforms by defining a weak
      symbol for sample_reg_masks[] in util/perf_regs.c.

      The patch also moves the REG() and REG_END() macros into the
      util/per_regs.h header file. The macros are renamed to
      SMPL_REG/SMPL_REG_END to avoid clashes with other header files.

      perf dwarf: Fix potential array out of bounds access

      There is a problem in the dwarf-regs.c files for sh, sparc and x86 where
      it is possible to make an out-of-bounds array access when searching for
      register names.

      This patch fixes it by replacing '<=' to '<', so when register (number
      == XXX_MAX_REGS), get_arch_regstr() will return NULL.

      cpufreq: update user_policy.* on success

      'user_policy' caches properties of a policy that are set by userspace.
      And these must be updated only if cpufreq core was successful in
      updating them based on request from user space.

      In store_scaling_governor(), we are updating user_policy.policy and
      user_policy.governor even if cpufreq_set_policy() failed. That's
      incorrect.

      Fix this by updating user_policy.* only if we were successful in
      updating the properties.

      cpufreq_get_policy() is useful if the pointer to policy isn't available
      in advance. But if it is available, then there is no need to call
      cpufreq_get_policy(). Directly use memcpy() to copy the policy.

      What's being done from CPUFREQ_INCOMPATIBLE, can also be done with
      CPUFREQ_ADJUST. There is nothing special with CPUFREQ_INCOMPATIBLE
      notifier.

      This also updates the numbering of notifier events to remove holes.

      cpufreq: mediatek: Add MT8173 cpufreq driver

      Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and
      2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage
      inputs, Vproc and Vsram are supplied by two regulators. For the big
      cluster, two regulators come from different PMICs. In this case, when
      scaling voltage inputs of the cluster, the voltages of two regulator
      inputs need to be controlled by software explicitly under the SoC
      specific limitation:

        100mV < Vsram - Vproc < 200mV

      which is called 'voltage tracking' mechanism. And when scaling the
      frequency of cluster clock input, the input MUX need to be parented to
      another "intermediate" stable PLL first and reparented to the original
      PLL once the original PLL is stable at the target frequency. This patch
      implements those mechanisms to enable CPU DVFS support for Mediatek
      MT8173 SoC.

      netfilter: conntrack: use nf_ct_tmpl_free in CT/synproxy error paths

      Commit 0838aa7fcfcd ("netfilter: fix netns dependencies with conntrack
      templates") migrated templates to the new allocator api, but forgot to
      update error paths for them in CT and synproxy to use nf_ct_tmpl_free()
      instead of nf_conntrack_free().

      Due to that, memory is being freed into the wrong kmemcache, but also
      we drop the per net reference count of ct objects causing an imbalance.

      In Brad's case, this leads to a wrap-around of net->ct.count and thus
      lets __nf_conntrack_alloc() refuse to create a new ct object:

        [   10.340913] xt_addrtype: ipv6 does not support BROADCAST matching
        [   10.810168] nf_conntrack: table full, dropping packet
        [   11.917416] r8169 0000:07:00.0 eth0: link up
        [   11.917438] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
        [   12.815902] nf_conntrack: table full, dropping packet
        [   15.688561] nf_conntrack: table full, dropping packet
        [   15.689365] nf_conntrack: table full, dropping packet
        [   15.690169] nf_conntrack: table full, dropping packet
        [   15.690967] nf_conntrack: table full, dropping packet
        [...]

      With slab debugging, it also reports the wrong kmemcache (kmalloc-512 vs.
      nf_conntrack_ffffffff81ce75c0) and reports poison overwrites, etc. Thus,
      to fix the problem, export and use nf_ct_tmpl_free() instead.

      i915: Set ddi_pll_sel in DP MST path

      The DP MST encoder config function never sets ddi_pll_sel, even though
      its value is programmed in its ->pre_enable() hook. That used to work
      because a new pipe_config was kzalloc'ed at every modeset, and the value
      of zero selects the highest clock for the PLL. Starting with the commit
      below, the value of ddi_pll_sel is preserved through modesets, and since
      the correct value wasn't properly setup by the MST code, it could lead
      to warnings and blank screens.

      from VBT with the SSC status set by BIOS.

      However, intel_modeset_gem_init is invoked *after* intel_modeset_init,
      which calls intel_setup_outputs, which *modifies* SSC status by way of
      intel_init_pch_refclk. So unlike advertised, intel_modeset_gem_init
      doesn't preserve the SSC status set by BIOS but whatever
      intel_init_pch_refclk decided on.

      This is a problem on dual gpu laptops such as the MacBook Pro which
      require either a handler to switch DDC lines, or the discrete gpu
      to proxy DDC/AUX communication: Both the handler and the discrete
      gpu may initialize after the i915 driver, and consequently, an LVDS
      connector may initially seem disconnected and the SSC therefore
      is disabled by intel_init_pch_refclk, but on reprobe the connector
      may turn out to be connected and the SSC must then be enabled.

      Due to 92122789b2d6 however, the SSC is not enabled on reprobe since
      it is assumed BIOS disabled it while in fact it was disabled by
      intel_init_pch_refclk.

      Also, because the SSC status is preserved so late, the preserved value
      only ever gets used on resume but not on panel initialization:
      intel_modeset_init calls intel_init_display which indirectly calls
      intel_panel_use_ssc via multiple subroutines, *before* the BIOS value
      overrides the VBT value in intel_modeset_gem_init (intel_panel_use_ssc
      is the sole user of dev_priv->vbt.lvds_use_ssc).

      Fix this by moving the code introduced by 92122789b2d6 from
      intel_modeset_gem_init to intel_modeset_init before the invocation
      of intel_setup_outputs and intel_init_display.

      Add a DRM_DEBUG_KMS as suggested way back by Jani:

         - Add support for using several Intel PT features (CYC, MTC packets),
           the relevant documentation was updated in:
               tools/perf/Documentation/intel-pt.txt
           briefly describing those packets, its purposes, how to configure
           them in the event config terms and relevant external documentation
           for further reading.  (Adrian Hunter)

         - Introduce support for probing at an absolute address, for user and
           kernel 'perf probe's, useful when one have the symbol maps on a
           developer machine but not on an embedded system.  (Wang Nan)

         - Add Intel BTS support, with a call-graph script to show it and PT
           in use in a GUI using 'perf script' python scripting with
           postgresql and Qt.  (Adrian Hunter)

         - Allow selecting the type of callchains per event, including
           disabling callchains in all but one entry in an event list, to save
           space, and also to ask for the callchains collected in one event to
           be used in other events.  (Kan Liang)

         - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho
           de Melo)
             * A bunch more translate file/pathnames from pointers to strings.
             * Convert numbers to strings for the 'keyctl' syscall 'option'
               arg.
             * Add missing 'clockid' entries.

         - Introduce 'srcfile' sort key: (Andi Kleen)

             # perf record -F 10000 usleep 1
             # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
             <SNIP>
             # Overhead  Source File
                26.49%  copy_page_64.S
                 5.49%  signal.c
                 0.51%  msr.h
             #

           It can be combined with other fields, for instance, experiment with
           '-s srcfile,symbol'.

           There are some oddities in some distros and with some specific
           DSOs, being investigated, so your mileage may vary.

         - Support per-event 'freq' term: (Namhyung Kim)

             $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 
sleep 1
             $ perf evlist -F
             cpu/instructions,freq=1234/: sample_freq=1234
             cycles: sample_period=1000
             $

         - Deref sys_enter pointer args with contents from probe:vfs_getname,
           showing pathnames instead of pointers in many syscalls in 'perf
           trace'.  (Arnaldo Carvalho de Melo)

         - Stop collecting /proc/kallsyms in perf.data files, saving about
           4.5MB on a typical x86-64 system, use the the symbol resolution
           routines used in all the other tools (report, top, etc) now that we
           can ask libtraceevent to use perf's symbol resolution code.
           (Arnaldo Carvalho de Melo)

         - Allow filtering out of perf's PID via 'perf record --exclude-perf'.
           (Wang Nan)

         - 'perf trace' now supports syscall groups, like strace, i.e:

             $ trace -e file touch file

           Will expand 'file' into multiple, file related, syscalls.  More
           work needed to add extra groups for other syscall groups, and also
           to complement what was added for the 'file' group, included as a
           proof of concept.  (Arnaldo Carvalho de Melo)

         - Add lock_pi stresser to 'perf bench futex', to test the kernel code
           related to FUTEX_(UN)LOCK_PI.  (Davidlohr Bueso)

         - Let user have timestamps with per-thread recording in 'perf record'
           (Adrian Hunter)

      ipv6: send NEWLINK on RA managed/otherconf changes

      The kernel is applying the RA managed/otherconf flags silently and
      forgets to send ifinfo notify to inform about their change when the
      router provides a zero reachable_time and retrans_timer as dnsmasq
      and many routers send it, which just means unspecified by this router
      and the host should continue using whatever value it is already using.
      Userspace may monitor the ifinfo notifications to activate dhcpv6.

      ====================
      DSA port configuration and status

      This patchset allows various switch port settings to be configured and
      port status to be sampled. Some of these patches have been posted
      before.

      The first three patches provide infrastructure for configuring a
      switch ports link speed and duplex from a fixed_link phy.

      Patch four then uses this infrastructure to allow the CPU and DSA
      ports of a switch to be configured using a fixed-link property in the
      device tree.

      Patches five and six allow a phy-mode property to be specified in the
      device tree, and allow this to be used for configuring RGMII delays.

      Patches seven through nine allow link status, for example that of an
      SFP module, to be read from a gpio.

      Changes since v1:

      Rewrite 9/9 so that it hopefully does not regression on

      net: phy: fixed_phy: Set phy capabilities even when link down.

      What features a phy supports is masked in genphy_config_init() by
      looking at the PHYs BMSR register.

      If the link is down, fixed_phy_update_regs() will only set the auto-
      negotiation capable bit in BMSR. Thus genphy_config_init() comes to
      the conclusion the PHY can only perform 10/Half, and masks out the
      higher speed features. If however the link it up, BMSR is set to
      indicate the speed the PHY is capable of auto-negotiating, and
      genphy_config_init() does not mask out the high speed features.

      To fix this, when the link is down, have fixed_phy_update_regs() leave
      the link status, auto-negotiation complete, and link partner
      capabilities unset, but set all the local capabilities depending on
      the fixed phy speed.

      net: phy: Allow PHY devices to identify themselves as Ethernet switches, 
etc.

      Some Ethernet MAC drivers using the PHY library require the hardcoding
      of link parameters when interfaced to a switch device, SFP module,
      switch to switch port, etc. This has typically lead to various ad-hoc
      implementations looking like this:

      - using a "fixed PHY" emulated device, which will provide link
        indication towards the Ethernet MAC driver and hardware

      - pretend there is no PHY and hardcode link parameters, ala mv643x_eth

      Based on that, it is desireable to have the PHY drivers advertise the
      correct link parameters, just like regular Ethernet PHYs towards their
      CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able
      to tell whether this link should be monitored or not. In the context
      of an Ethernet switch, SFP module, switch to switch link, we do not
      need to monitor this link since it should be always up.

      perf record: Add ability to name registers to record

      This patch modifies the -I/--int-regs option to enablepassing the name
      of the registers to sample on interrupt. Registers can be specified by
      their symbolic names. For instance on x86, --intr-regs=ax,si.

      The motivation is to reduce the size of the perf.data file and the
      overhead of sampling by only collecting the registers useful to a
      specific analysis. For instance, for value profiling, sampling only the
      registers used to passed arguements to functions.

      With no parameter, the --intr-regs still records all possible registers
      based on the architecture.

      To name registers, it is necessary to use the long form of the option,
      i.e., --intr-regs:

        $ perf record --intr-regs=si,di,r8,r9 .....

      To record any possible registers:

        $ perf record -I .....
        $ perf report --intr-regs ...

      To display the register, one can use perf report -D

      To list the available registers:

        $ perf record --intr-regs=\?
        available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10 
R11 R12 R13 R14 R15

      nfsd: ensure that delegation stateid hash references are only put once

      It's possible that a DELEGRETURN could race with (e.g.) client expiry,
      in which case we could end up putting the delegation hash reference more
      than once.

      Have unhash_delegation_locked return a bool that indicates whether it
      was already unhashed. In the case of destroy_delegation we only
      conditionally put the hash reference if that returns true.

      The other callers of unhash_delegation_locked call it while walking
      list_heads that shouldn't yet be detached. If we find that it doesn't
      return true in those cases, then throw a WARN_ON as that indicates that
      we have a partially hashed delegation, and that something is likely very
      wrong.

      nfsd: ensure that the ol stateid hash reference is only put once

      When an open or lock stateid is hashed, we take an extra reference to
      it. When we unhash it, we drop that reference. The code however does
      not properly account for the case where we have two callers concurrently
      trying to unhash the stateid. This can lead to list corruption and the
      hash reference being put more than once.

      Fix this by having unhash_ol_stateid use list_del_init on the st_perfile
      list_head, and then testing to see if that list_head is empty before
      releasing the hash reference. This means that some of the unhashing
      wrappers now become bool return functions so we can test to see whether
      the stateid was unhashed before we put the reference.

      Actually TP_printk() should never dereference an address saved in the ring
      buffer that points somewhere in the kernel. There's no guarantee that that
      object still exists (with the exception of static strings).

      Therefore change all the arguments for TP_printk(), so that it references
      values existing in the ring buffer only.

      While doing that, also fix another possible bug when argument xprt could 
be
      NULL and TP_fast_assign() tries to access it's elements.

      nfsd: allow more than one laundry job to run at a time

      We can potentially have several nfs4_laundromat jobs running if there
      are multiple namespaces running nfsd on the box. Those are effectively
      separated from one another though, so I don't see any reason to
      serialize them.

      Also, create_singlethread_workqueue automatically adds the
      WQ_MEM_RECLAIM flag. Since we run this job on a timer, it's not really
      involved in any reclaim paths. I see no need for a rescuer thread.

      nfsd: don't WARN/backtrace for invalid container deployment.

      These messages, combined with the backtrace they trigger, makes it seem
      like a serious problem, though a quick search shows distros marking
      it as a "won't fix" non-issue when the problem is reported by users.

      The backtrace is overkill, and only really manages to show that if
      you follow the code path, you can't really avoid it with bootargs
      or configuration settings in the container.

      Given that, lets tone it down a bit and get rid of the WARN severity,
      and the associated backtrace, so people aren't needlessly alarmed.

      Also, lets drop the split printk line, since they are grep unfriendly.

      bpf tools: New API to get name from a BPF object

      Before this patch there's no way to connect a loaded bpf object
      to its source file. However, during applying perf's '--filter' to BPF
      object, without this connection makes things harder, because perf loads
      all programs together, but '--filter' setting is for each object.

      The API of bpf_object__open_buffer() is changed to allow passing a name.
      Fortunately, at this time there's only one user of it (perf test LLVM),
      so we change it together.

      Daniel Borkmann says:

      ====================
      tcp: receive-side per route dctcp handling

      Original cover letter:

        Currently, the following case doesn't use DCTCP, even if it should:

          - responder has f.e. cubic as system wide default
          - 'ip route congctl dctcp $src' was set

        Then, DCTCP is NOT used if a DCTCP sender attempts to connect from a
        host in the $src range: ECT(0) is set, but listen_sk is not dctcp, so
        we fail the INET_ECN_is_not_ect sanity check.

        We also have to examine the dst used for the SYN/ACK reply to make
        this case work.

        In order to minimize additional cost, store the 'ecn is must have'
        information is the dst_features field.

        The set targets -next instead of -net since this doesn't seem to be a
        serious bug and to give the change more soak time until it hits linus
        tree.

      v1 -> v2:
       - Addressed Dave's feedback, not exposing any bits to user space
       - Added patch 3 to reject incorrect configurations
       - Rest as is, rebased and retested

      tcp: use dctcp if enabled on the route to the initiator

      Currently, the following case doesn't use DCTCP, even if it should:
      A responder has f.e. Cubic as system wide default, but for a specific
      route to the initiating host, DCTCP is being set in RTAX_CC_ALGO. The
      initiating host then uses DCTCP as congestion control, but since the
      initiator sets ECT(0), tcp_ecn_create_request() doesn't set ecn_ok,
      and we have to fall back to Reno after 3WHS completes.

      We were thinking on how to solve this in a minimal, non-intrusive
      way without bloating tcp_ecn_create_request() needlessly: lets cache
      the CA ecn option flag in RTAX_FEATURES. In other words, when ECT(0)
      is set on the SYN packet, set ecn_ok=1 iff route RTAX_FEATURES
      contains the unexposed (internal-only) DST_FEATURE_ECN_CA. This allows
      to only do a single metric feature lookup inside tcp_ecn_create_request().

      perf tools: Fix build on powerpc broken by pt/bts

      It is theoretically possible to process perf.data files created on x86
      and that contain Intel PT or Intel BTS data, on any other architecture,
      which is why it is possible for there to be build errors on powerpc
      caused by pt/bts.

      The errors were:

      btrfs: async_thread: Fix workqueue 'max_active' value when initializing

      At initializing time, for threshold-able workqueue, it's max_active
      of kernel workqueue should be 1 and grow if it hits threshold.

      But due to the bad naming, there is both 'max_active' for kernel
      workqueue and btrfs workqueue.
      So wrong value is given at workqueue initialization.

      This patch fixes it, and to avoid further misunderstanding, change the
      member name of btrfs_workqueue to 'current_active' and 'limit_active'.

      Also corresponding comment is added for readability.

      btrfs: Add raid56 support for updating
       num_tolerated_disk_barrier_failures in btrfs_balance

      Code for updating fs_info->num_tolerated_disk_barrier_failures in
      btrfs_balance() lacks raid56 support.

      Reason:
       Above code was wroten in 2012-08-01, together with
       btrfs_calc_num_tolerated_disk_barrier_failures()'s first version.

       Then, btrfs_calc_num_tolerated_disk_barrier_failures() got updated
       later to support raid56, but code in btrfs_balance() was not
       updated together.

      Fix:
       Merge above similar code to a common function:
       btrfs_get_num_tolerated_disk_barrier_failures()
       and make it support both case.

       It can fix this bug with a bonus of cleanup, and make these code
       never in above no-sync state from now on.

         make logic neat.

      md/raid5: ensure device failure recorded before write request returns.

      When a write to one of the devices of a RAID5/6 fails, the failure is
      recorded in the metadata of the other devices so that after a restart
      the data on the failed drive wont be trusted even if that drive seems
      to be working again (maybe a cable was unplugged).

      Similarly when we record a bad-block in response to a write failure,
      we must not let the write complete until the bad-block update is safe.

      Currently there is no interlock between the write request completing
      and the metadata update.  So it is possible that the write will
      complete, the app will confirm success in some way, and then the
      machine will crash before the metadata update completes.

      This is an extremely small hole for a racy to fit in, but it is
      theoretically possible and so should be closed.

      So:
       - set MD_CHANGE_PENDING when requesting a metadata update for a
         failed device, so we can know with certainty when it completes
       - queue requests that completed when MD_CHANGE_PENDING is set to
         only be processed after the metadata update completes
       - call raid_end_bio_io() on bios in that queue when the time comes.

      To fix this problem, we do the following changes:

      1. the sender downconverts MESSAGE to CW rather than CR.
      2. and the receiver request PR lock not EX lock on message.

      And in case we failed to down-convert EX to CW on message, it is better to
      unlock message otherthan still hold the lock.

      md-cluster: transfer the resync ownership to another node

      When node A stops an array while the array is doing a resync, we need
      to let another node B take over the resync task.

      To achieve the goal, we need the A send an explicit BITMAP_NEEDS_SYNC
      message to the cluster. And the node B which received that message will
      invoke __recover_slot to do resync.

      md/raid5: handle possible race as reshape completes.

      It is possible (though unlikely) for a reshape to be
      interrupted between the time that end_reshape is called
      and the time when raid5_finish_reshape is called.

      This can leave conf->reshape_progress set to MaxSector,
      but mddev->reshape_position not.

      This combination confused reshape_request() when ->reshape_backwards.
      As conf->reshape_progress is so high, it seems the reshape hasn't
      really begun.  But assuming MaxSector is a valid address only
      leads to sorrow.

      So ensure reshape_position and reshape_progress both agree,
      and add an extra check in reshape_request() just in case they don't.

      md: sync sync_completed has correct value as recovery finishes.

      There can be a small window between the moment that recovery
      actually writes the last block and the time when various sysfs
      and /proc/mdstat attributes report that it has finished.
      During this time, 'sync_completed' can have the wrong value.
      This can confuse monitoring software.

      So:
       - don't set curr_resync_completed beyond the end of the devices,
       - set it correctly when resync/recovery has completed.

      md: be careful when testing resync_max against curr_resync_completed.

      While it generally shouldn't happen, it is not impossible for
      curr_resync_completed to exceed resync_max.
      This can particularly happen when reshaping RAID5 - the current
      status isn't copied to curr_resync_completed promptly, so when it
      is, it can exceed resync_max.
      This happens when the reshape is 'frozen', resync_max is set low,
      and reshape is re-enabled.

      Taking a difference between two unsigned numbers is always dangerous
      anyway, so add a test to behave correctly if
         curr_resync_completed > resync_max

      md/raid5: remove incorrect "min_t()" when calculating writepos.

      This code is calculating:
        writepos, which is the furthest along address (device-space) that we
           *will* be writing to
        readpos, which is the earliest address that we *could* possible read
           from, and
        safepos, which is the earliest address in the 'old' section that we
           might read from after a crash when the reshape position is
           recovered from metadata.

        The first is a precise calculation, so clipping at zero doesn't
        make sense.  As the reshape position is now guaranteed to always be
        a multiple of reshape_sectors and as we already BUG_ON when
        reshape_progress is zero, there is no point in this min_t() call.

        The readpos and safepos are worst case - actual value depends on
        precise geometry.  That worst case could be negative, which is only
        a problem because we are storing the value in an unsigned.
        So leave the min_t() for those.

      md/raid5: strengthen check on reshape_position at run.

      When reshaping, we work in units of the largest chunk size.
      If changing from a larger to a smaller chunk size, that means we
      reshape more than one stripe at a time.  So the required alignment
      of reshape_position needs to take into account both the old
      and new chunk size.

      This means that both 'here_new' and 'here_old' are calculated with
      respect to the same (maximum) chunk size, so testing if they are the
      same when delta_disks is zero becomes pointless.

      md/raid5: switch to use conf->chunk_sectors in place of 
mddev->chunk_sectors where possible

      The chunk_sectors and new_chunk_sectors fields of mddev can be changed
      any time (via sysfs) that the reconfig mutex can be taken.  So raid5
      keeps internal copies in 'conf' which are stable except for a short
      locked moment when reshape stops/starts.

      So any access that does not hold reconfig_mutex should use the 'conf'
      values, not the 'mddev' values.
      Several don't.

      This could result in corruption if new values were written at awkward
      times.

      Also use min() or max() rather than open-coding.

      The next patch will use ->prev_chunk_sectors without checking

      and this patch makes that safe.

      md/raid5: consider updating reshape_position at start of reshape.

      md/raid5 only updates ->reshape_position (which is stored in
      metadata and is authoritative) occasionally, but particularly
      when getting closed to ->resync_max as it must be correct
      when ->resync_max is reached.

      When mdadm tries to stop an array which is reshaping it will:
       - freeze the reshape,
       - set resync_max to where the reshape has reached.
       - unfreeze the reshape.
      When this happens, the reshape is aborted and then restarted.

      The restart doesn't check that resync_max is close, and so doesn't
      update ->reshape_position like it should.
      This results in the reshape stopping, but ->reshape_position being
      incorrect.

      So on that first call to reshape_request, make sure ->reshape_position
      is updated if needed.

      md: close some races between setting and checking sync_action.

      When checking sync_action in a script, we want to be sure it is
      as accurate as possible.
      As resync/reshape etc doesn't always start immediately (a separate
      thread is scheduled to do it), it is best if 'action_show'
      checks if MD_RECOVER_NEEDED is set (which it does) and in that
      case reports what is likely to start soon (which it only sometimes
      does).

      So:
       - report 'reshape' if reshape_position suggests one might start.
       - set MD_RECOVERY_RECOVER in raid1_reshape(), because that is very
         likely to happen next.

      md: Keep /proc/mdstat reporting recovery until fully DONE.

      Currently when a recovery completes, mdstat shows that it has finished
      before the new device is marked as a full member.  Because of this it
      can appear to a script that the recovery finished but the array isn't
      in sync.

      So while MD_RECOVERY_DONE is still set, keep mdstat reporting "recovery".
      Once md_reap_sync_thread() completes, the spare will be active and then
      MD_RECOVERY_DONE will be cleared.

      To ensure this is race-free, set MD_RECOVERY_DONE before clearning
      curr_resync.

        Not much really interesting here, just a number of little changes all
        over the place, and some nice consolidation of the nvmem drivers to a
        common framework.  As usual, the mei drivers stand out as the largest

      drm/i915/skl: Enable DDI-E

      There are OEMs using DDI-E out there,
      so let's enable it.

      Unfortunately there is no detection bit for DDI-E
      So we need to rely on VBT for that.

      I also need to give credits to Xiong since before seing
      his approach to check info->support_* I was creating an ugly
      vbt->ddie_sfuse_strap in order to propagate the ddi presence info

      v2: Rebased as last patch in the series. since all other patches
      in this series are needed for anything working propperly on DDI-E.

          drm/i915: gen4: work around hang during hibernation

      using an explicit blacklist for the GENs/BIOS vendors where the issue was
      reported. Later there we had reports of the same failure on platforms not 
on
      this list.

      To my best knowledge the correct thing to do is still to put the device 
to PCI
      D3 state during hibernation, see [1] and [2] for the reasons. This also 
aligns
      with our future plans to unify more the runtime and system suspend/resume
      paths. Since an exact blacklist seems to be impractical (multiple GENs and
      BIOS vendors are affected) apply the workaround on everything pre GEN6.

      drm/i915: Check DP link status on long hpd too

      We are no longer checkling the DP link status on long hpd. We used to do
      that from the .hot_plug() handler, but it was removed when MST got
      introduced.

      If there's no userspace we now fail to retrain the link if the sink
      power is toggled (or cable yanked and replugged), meaning the user is
      left staring at a blank screen. With the retraining put back that should
      be fixed.

      Also remove the leftover comment that referred to the old retraining
      from .hot_plug().

      Fixes a regression introduced in:

      tracing: Don't make assumptions about length of string on task rename

      While the dest comm string size is assured to be at least TASK_COMM_LEN 
long,
      doing a memcpy() also adds the assumption that the source is at least that
      long as well, which isn't assured, and isn't true in cases such as:

        set_task_comm(worker->task, "kworker/dying");

      This leads to accessing invalid memory.

      regmap: Support bulk reads for devices without raw formatting

      When doing a bulk read from a device which lacks raw I/O support we fall
      back to doing register at a time reads but we still use the raw
      formatters in order to render the data into the word size used by the
      device (since bulk reads still operate on the device word size rather
      than unsigned ints).  This means that devices without raw formatting
      such as those that provide reg_read() are not supported.  Provide
      handling for them by copying the values read into native endian values
      of the appropriate size.

      NFSv4.1/pnfs: Handle LAYOUTGET return values correctly

      According to RFC5661 section 18.43.3, if the server cannot satisfy
      the loga_minlength argument to LAYOUTGET, there are 2 cases:
      1) If loga_minlength == 0, it returns NFS4ERR_LAYOUTTRYLATER
      2) If loga_minlength != 0, it returns NFS4ERR_BADLAYOUT

      Because in SMP, "mrq" has race condition between below two paths:
      path1: CPU0: <tasklet context>
        static void mmc_wait_data_done(struct mmc_request *mrq)
        {
           mrq->host->context_info.is_done_rcv = true;
           //
           // If CPU0 has just finished "is_done_rcv = true" in path1, and at
           // this moment, IRQ or ICache line missing happens in CPU0.
           // What happens in CPU1 (path2)?
           //
           // If the mmcqd thread in CPU1(path2) hasn't entered to sleep mode:
           // path2 would have chance to break from wait_event_interruptible
           // in mmc_wait_for_data_req_done and continue to run for next
           // mmc_request (mmc_blk_rw_rq_prep).
           //
           // Within mmc_blk_rq_prep, mrq is cleared to 0.
           // If below line still gets host from "mrq" as the result of
           // compiler, the panic happens as we traced.
           wake_up_interruptible(&mrq->host->context_info.wait);
        }

      path2: CPU1: <The mmcqd thread runs mmc_queue_thread>
        static int mmc_wait_for_data_req_done(...
        {
           ...
           while (1) {
                 wait_event_interruptible(context_info->wait,
                         (context_info->is_done_rcv ||
                          context_info->is_new_req));
                   static void mmc_blk_rw_rq_prep(...
                 {
                 ...
                 memset(brq, 0, sizeof(struct mmc_blk_request));

      This issue happens very coincidentally; however adding mdelay(1) in
      mmc_wait_data_done as below could duplicate it easily.

         static void mmc_wait_data_done(struct mmc_request *mrq)
         {
           mrq->host->context_info.is_done_rcv = true;
      +    mdelay(1);
           wake_up_interruptible(&mrq->host->context_info.wait);
          }

      At runtime, IRQ or ICache line missing may just happen at the same place
      of the mdelay(1).

      This patch gets the mmc_context_info at the beginning of function, it can
      avoid this race condition.

      netlink: rx mmap: fix POLLIN condition

      Poll() returns immediately after setting the kernel current frame
      (ring->head) to SKIP from user space even though there is no new
      frame. And in a case of all frames is VALID, user space program
      unintensionally sets (only) kernel current frame to UNUSED, then
      calls poll(), it will not return immediately even though there are
      VALID frames.

      To avoid situations like above, I think we need to scan all frames
      to find VALID frames at poll() like netlink_alloc_skb(),
      netlink_forward_ring() finding an UNUSED frame at skb allocation.

      network connectivity.

      'loopback' mode can be enabled or disabled via ethtool.

      Note: This feature is not supported when no of VFs enabled are
      morethan no of physical interfaces i.e active BGX LMACs

      net: thunderx: Support for upto 96 queues for a VF

      This patch adds support for handling multiple qsets assigned to a
      single VF. There by increasing no of queues from earlier 8 to max
      no of CPUs in the system i.e 48 queues on a single node and 96 on
      dual node system. User doesn't have option to assign which Qsets/VFs
       to be merged. Upon request from VF, PF assigns next free Qsets as
      secondary qsets. To maintain current behavior no of queues is kept
      to 8 by default which can be increased via ethtool.

      If user wants to unbind NICVF driver from a secondary Qset then it
      should be done after tearing down primary VF's interface.

      net: thunderx: Support for HW VLAN stripping

      This patch configures HW to strip 802.1Q header if found in a
      receiving packet. The stripped VLAN ID and TCI information is
      passed on to software via CQE_RX. Also sets netdev's 'vlan_features'
      so that other HW offload features can be used for tagged packets.

      This offload feature can be enabled or disabled via ethtool.

      Network stack normally ignores RPS for 802.1Q packets and hence low
      throughput. With this offload enabled throughput for tagged packets
      will be almost same as normal packets.

      Note: This patch doesn't enable HW VLAN insertion for transmit packets.

      Raghavendra K T says:

      ====================
      Optimize the snmp stat aggregation for large cpus

      While creating 1000 containers, perf is showing lot of time spent in
      snmp_fold_field on a large cpu system.

      The current patch tries to improve by reordering the statistics gathering.

      Please note that similar overhead was also reported while creating
      veth pairs  https://lkml.org/lkml/2013/3/19/556

      Changes in V4:
       - remove 'item' variable and use IPSTATS_MIB_MAX to avoid sparse
         warning (Eric) also remove 'item' parameter (Joe)
       - add missing memset of padding.

      Changes in V3:
       - use memset to initialize temp buffer in leaf function. (David)
       - use memcpy to copy the buffer data to stat instead of unalign_pu (Joe)
       - Move buffer definition to leaf function __snmp6_fill_stats64() (Eric)
       -
      Changes in V2:
       - Allocate the stat calculation buffer in stack. (Eric)

      Setup:
      160 cpu (20 core) baremetal powerpc system with 1TB memory

      1000 docker containers was created with command
      docker run -itd  ubuntu:15.04  /bin/bash in loop

      observation:
      Docker container creation linearly increased from around 1.6 sec to 7.5 
sec
      (at 1000 containers) perf data showed, creating veth interfaces resulting 
in
      the below code path was taking more time.

      rtnl_fill_ifinfo
        -> inet6_fill_link_af
          -> inet6_fill_ifla6_attrs
            -> snmp_fold_field

      proposed idea:
       currently __snmp6_fill_stats64 calls snmp_fold_field that walks

      net: Optimize snmp stat aggregation by walking all the percpu data at once

      Docker container creation linearly increased from around 1.6 sec to 7.5 
sec
      (at 1000 containers) and perf data showed 50% ovehead in snmp_fold_field.

      reason: currently __snmp6_fill_stats64 calls snmp_fold_field that walks
      through per cpu data of an item (iteratively for around 36 items).

      idea: This patch tries to aggregate the statistics by going through
      all the items of each cpu sequentially which is reducing cache
      misses.

      Docker creation got faster by more than 2x after the patch.

      Result:
                             Before           After
      Docker creation time   6.836s           3.25s

      NFSv4.1: Fix a protocol issue with CLOSE stateids

      According to RFC5661 Section 18.2.4, CLOSE is supposed to return
      the zero stateid. This means that nfs_clear_open_stateid_locked()
      cannot assume that the result stateid will always match the 'other'
      field of the existing open stateid when trying to determine a race
      with a parallel OPEN.

      Instead, we look at the argument, and check for matches.

      IB/ucma: HW Device hot-removal support

      Currently, IB/cma remove_one flow blocks until all user descriptor 
managed by
      IB/ucma are released. This prevents hot-removal of IB devices. This patch
      allows IB/cma to remove devices regardless of user space activity. Upon 
getting
      the RDMA_CM_EVENT_DEVICE_REMOVAL event we close all the underlying HW 
resources
      for the given ucontext. The ucontext itself is still alive till its 
explicit
      destroying by its creator.

      Running applications at that time will have some zombie device, further
      operations may fail.

      IB/mlx4_ib: Disassociate support

      Implements the IB core disassociate_ucontext API. The driver detaches the 
HW
      resources for a given user context to prevent a dependency between 
application
      termination and device disconnecting. This is done by managing the VMAs 
that
      were mapped to the HW bars such as door bell and blueflame. When need to 
detach
      remap them to an arbitrary kernel page returned by the zap API.

      IB/uverbs: Enable device removal when there are active user space 
applications

      Enables the uverbs_remove_one to succeed despite the fact that there are
      running IB applications working with the given ib device.  This
      functionality enables a HW device to be unbind/reset despite the fact that
      there are running user space applications using it.

      It exposes a new IB kernel API named 'disassociate_ucontext' which lets
      a driver detaching its HW resources from a given user context without
      crashing/terminating the application. In case a driver implemented the
      above API and registered with ib_uverb there will be no dependency 
between its
      device to its uverbs_device. Upon calling remove_one of ib_uverbs the call
      should return after disassociating the open HW resources without waiting 
to
      clients disconnecting. In case driver didn't implement this API there 
will be no
      change to current behaviour and uverbs_remove_one will return only when 
last
      client has disconnected and reference count on uverbs device became 0.

      In case the lower driver device was removed any application will
      continue working over some zombie HCA, further calls will ended with an
      immediate error.

      IB/uverbs: Fix race between ib_uverbs_open and remove_one

      Fixes: 2a72f212263701b927559f6850446421d5906c41 ("IB/uverbs: Remove 
dev_table")

      Before this commit there was a device look-up table that was protected
      by a spin_lock used by ib_uverbs_open and by ib_uverbs_remove_one. When
      it was dropped and container_of was used instead, it enabled the race
      with remove_one as dev might be freed just after:
      dev = container_of(inode->i_cdev, struct ib_uverbs_device, cdev) but
      before the kref_get.

      In addition, this buggy patch added some dead code as
      container_of(x,y,z) can never be NULL and so dev can never be NULL.
      As a result the comment above ib_uverbs_open saying "the open method
      will either immediately run -ENXIO" is wrong as it can never happen.

      The solution follows Jason Gunthorpe suggestion from below URL:
      https://www.mail-archive.com/linux-rdma@xxxxxxxxxxxxxxx/msg25692.html

      cdev will hold a kref on the parent (the containing structure,
      ib_uverbs_device) and only when that kref is released it is
      guaranteed that open will never be called again.

      In addition, fixes the active count scheme to use an atomic
      not a kref to prevent WARN_ON as pointed by above comment
      from Jason.

      Fix the reference counting usage to be handled in the event file

      "The existing code for this is broken, in ib_uverbs_get_context all

      IB/core: Make ib_dealloc_pd return void

      The majority of callers never check the return value, and even if they
      did, they can't do anything about a failure.

      All possible failure cases represent a bug in the caller, so just
      WARN_ON inside the function instead.

      This fixes a few random errors:
       net/rd/iw.c infinite loops while it fails. (racing with EBUSY?)

      This also lays the ground work to get rid of error return from the
      drivers. Most drivers do not error, the few that do are broken since
      it cannot be handled.

      Since uverbs can legitimately make use of EBUSY, open code the
      check.

      IB/srp: Remove the memory registration backtracking code

      Mapping a discontiguous sg-list requires multiple memory regions
      and hence can exhaust the memory region pool. The SRP initiator
      already handles this by temporarily reducing the queue depth. This
      means that it is safe to remove the memory registration backtracking
      code. This patch has been tested with direct I/O sizes up to 256 MB.

      IB/iser: Support up to 8MB data transfer in a single command

      iser support up to 512KB data transfer in a single scsi command.
      This means that larger IOs will split to different request. While
      iser can easily saturate FDR/EDR wires, some arrays are fine tuned
      for 1MB (or larger) IO sizes, hence add an option to support larger
      transfers (up to 8MB) if the device allows it.

      Given that a few target implementations don't support data transfers
      of more than 512KB by default and the fact that larger IO sizes require
      more resources, we introduce a module parameter to determine the
      maximum number of 512B sectors in a single scsi command.
      Users that are interested in larger transfers can change this value given
      that the target supports larger transfers.

      At the moment, iser works in 4K pages granularity, In a later stage
      we will get it to work with system page size instead.

      IO operations that consists of N pages will need a page vector
      of size N+1 in case the first SG element contains an offset. Given
      that some devices allocates memory regions in powers of 2, this
      means that allocating a region with N+1 pages, will result in
      region resources allocation of the next power of 2. Since we don't
      want that to happen, in case we are in the limit of IO size supported
      and the first SG element has an offset, we align the SG list using a
      bounce buffer (which is OK given that this is not likely to happen a lot).

      The DIF logic is not implemented in the FMR flow as there is no

      This patch unifies the flow in a single routine iser_reg_rdma_mem
      and just split to fmr/frwr for the buffer registration itself.

      Also, for symmetry reasons, unify iser_unreg_rdma_mem (which will

      IB/iser: Introduce struct iser_reg_resources

      Have fast_reg_descriptor hold struct iser_reg_resources
      (mr, frpl, valid flag). This will be useful when the
      actual buffer registration routines will be passed with
      the needed registration resources (i.e. iser_reg_resources)
      without being aware of their nature (i.e. data or protection).

      In order to achieve this, we remove reg_indicators flags container
      and place specific flags (mr_valid) within iser_reg_resources struct.
      We also place the sig_mr_valid and sig_protcted flags in iser_pi_context.

      This patch also modifies iser_fast_reg_mr to receive the
      reg_resources instead of the fast_reg_descriptor and a data/protection

      IB/mlx4: Fix incorrect cq flushing in error state

      When handling a device internal error, the driver is responsible to
      drain the completion queue with flush errors.

      In case a completion queue was assigned to multiple send queues, the
      driver iterates over the send queues and generates flush errors of
      inflight wqes. The driver must correctly pass the wc array with an
      offset as a result of the previous send queue iteration. Not doing so
      will overwrite previously set completions and return a wrong number
      of polled completions which includes ones which were not correctly set.

      IB/core: Add RoCE table bonding support

      Handling bonding and other devices require us to all all GIDs of the
      net-devices which are upper-devices of the RoCE port related
      net-device.

      Active-backup configurations imposes even more challenges as the
      default GID should only be set on the active devices (this is
      necessary as otherwise the same MAC could be used for several
      slaves and thus several slaves will have identical GIDs).

      Managing these configurations are done by listening to:
      (a) NETDEV_CHANGEUPPER event
        (1) if a related net-device is linked, delete all inactive
            slaves default GIDs and add the upper device GIDs.
        (2) if a related net-device is unlinked, delete all upper GIDs
            and add the default GIDs.
      (b) NETDEV_BONDING_FAILOVER:
        (1) delete the bond GIDs from inactive slaves
        (2) delete the inactive slave's default GIDs
        (3) Add the bond GIDs to the active slave.

      IB/core: Add RoCE GID table management

      RoCE GIDs are based on IP addresses configured on Ethernet net-devices
      which relate to the RDMA (RoCE) device port.

      mlx4) manages its own RoCE port GID table. As there's nothing which is
      essentially vendor specific, we generalize that, and enhance the RDMA
      core GID cache to do this job.

      In order to populate the GID table, we listen for events:

      (a) netdev up/down/change_addr events - if a netdev is built onto
          our RoCE device, we need to add/delete its IPs. This involves
          adding all GIDs related to this ndev, add default GIDs, etc.

      (b) inet events - add new GIDs (according to the IP addresses)
          to the table.

      For programming the port RoCE GID table, providers must implement
      the add_gid and del_gid callbacks.

      RoCE GID management requires us to state the associated net_device
      alongside the GID. This information is necessary in order to manage
      the GID table. For example, when a net_device is removed, its
      associated GIDs need to be removed as well.

      RoCE mandates generating a default GID for each port, based on the
      related net-device's IPv6 link local. In contrast to the GID based on
      the regular IPv6 link-local (as we generate GID per IP address),
      the default GID is also available when the net device is down (in
      order to support loopback).

      Locking is done as follows:
      The patch modify the GID table code both for new RoCE drivers
      implementing the add_gid/del_gid callbacks and for current RoCE and
      IB drivers that do not. The flows for updating the table are
      different, so the locking requirements are too.

      While updating RoCE GID table, protection against multiple writers is
      achieved via mutex_lock(&table->lock). Since writing to a table
      requires us to find an entry (possible a free entry) in the table and
      then modify it, this mutex protects both the find_gid and write_gid
      ensuring the atomicity of the action.
      Each entry in the GID cache is protected by rwlock. In RoCE, writing
      (usually results from netdev notifier) involves invoking the vendor's
      add_gid and del_gid callbacks, which could sleep.
      Therefore, an invalid flag is added for each entry. Updates for RoCE are
      done via a workqueue, thus sleeping is permitted.

      In IB, updates are done in write_lock_irq(&device->cache.lock), thus
      write_gid isn't allowed to sleep and add_gid/del_gid are not called.

      When passing net-device into/out-of the GID cache, the device
      is always passed held (dev_hold).

      The code uses a single work item for updating all RDMA devices,
      following a netdev or inet notifier.

      The patch moves the cache from being a client (which was incorrect,
      as the cache is part of the IB infrastructure) to being explicitly
      initialized/freed when a device is registered/removed.

      This gets rid of the weird in-between state where struct ib_device
      was allocated but the kobject didn't work.

      Consequently ib_device_release is now guaranteed to be called in

      Some consumers of the netdev events API would like to know who is the

      net/ipv6: Export addrconf_ifid_eui48

      For loopback purposes, RoCE devices should have a default GID in the
      port GID table, even when the interface is down. In order to do so,
      we use the IPv6 link local address which would have been genenrated
      for the related Ethernet netdevice when it goes up as a default GID.

      addrconf_ifid_eui48 is used to gernerate this address, export it.

      IB/cma: Refactor RDMA IP CM private-data parsing code

      When receiving a connection request, rdma_cm needs to associate the 
request
      with a network device, in order to disambiguate requests. To do this, it
      needs to know the request's destination IP. For this the module needs to
      allow getting this information from the private data in the request 
packet,
      instead of relying on the information already being in the listening RDMA
      CM ID.

      When creating a new incoming connection ID, the code in
      cma_save_ip{4,6}_info can no longer rely on the listener's private data to
      find the port number, so it reads it from the requested service ID.

      IB/cm: Share listening CM IDs

      Enabling network namespaces for RDMA CM will allow processes on different
      namespaces to listen on the same port. In order to leave namespace support
      out of the CM layer, this requires that multiple RDMA CM IDs will be able
      to share a single CM ID.

      This patch adds infrastructure to retrieve an existing listening ib_cm_id,
      based on its device and service ID, or create a new one if one does not
      already exist. It also adds a reference count for such instances
      (cm_id_private.listen_sharecount), and prevents cm_destroy_id from
      destroying a CM if it is still shared. See the relevant discussion [1].

      IB/core: Find the network device matching connection parameters

      In the case of IPoIB, and maybe in other cases, the network device is
      managed by an upper-layer protocol (ULP). In order to expose this
      network device to other users of the IB device, let ULPs implement
      a callback that returns network device according to connection parameters.

      The IB device and port, together with the P_Key and the GID should
      be enough to uniquely identify the ULP net device. However, in current
      kernels there can be multiple IPoIB interfaces created with the same GID.
      Furthermore, such configuration may be desireable to support ipvlan-like
      configurations for RDMA CM with IPoIB.  To resolve the device in these
      cases the code will also take the IP address as an additional input.

      IB/core: lock client data with lists_rwsem

      An ib_client callback that is called with the lists_rwsem locked only for
      read is protected from changes to the IB client lists, but not from
      ib_unregister_device() freeing its client data. This is because
      ib_unregister_device() will remove the device from the device list with
      lists_rwsem locked for write, but perform the rest of the cleanup,
      including the call to remove() without that lock.

      Mark client data that is undergoing de-registration with a new going_down
      flag in the client data context. Lock the client data list with 
lists_rwsem
      for write in addition to using the spinlock, so that functions calling the
      callback would be able to lock only lists_rwsem for read and let callbacks
      sleep.

      Since ib_unregister_client() now marks the client data context, no need 
for
      remove() to search the context again, so pass the client data directly to
      remove() callbacks.

      IB/core: Add rwsem to allow reading device list or client list

      Currently the RDMA subsystem's device list and client list are protected 
by
      a single mutex. This prevents adding user-facing APIs that iterate these
      lists, since using them may cause a deadlock. The patch attempts to solve
      this problem by adding a read-write semaphore to protect the lists. 
Readers
      now don't need the mutex, and are safe just by read-locking the semaphore.

      The ib_register_device, ib_register_client, ib_unregister_device, and
      ib_unregister_client functions are modified to lock the semaphore for 
write
      during their respective list modification. Also, in order to make sure
      client callbacks are called only between add() and remove() calls, the 
code
      is changed to only add items to the lists after the add() calls and remove
      from the lists before the remove() calls.

      This patch attempts to solve a similar need [1] that was seen in the RoCE
      v2 patch series.

      drm/exynos: fimd: move window protect code to prepare/cleanup_plane

      Only set/clear the update bit in the CRTC's .atomic_begin()/flush()
      so all planes are really committed at the same time.

      drm/exynos: add prepare and cleanup phases for planes

      From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

      .prepare_plane() and .cleanup_plane() allows to perform extra operations
      before and after the update of planes. For FIMD for example this will
      be used to enable disable the shadow protection bit.

      Unify handling of finished plane update to prepare for a following patch
      that will check for the START and START_S regs to really make sure that
      the plane was updated.

      drm/exynos: don't track enabled state at exynos_crtc

      struct drm_crtc already stores the enabled state of the crtc
      thus we don't need to replicate enabled in exynos_drm_crtc.

      and also "ad5398-regulator" is not a supported I2C id, so it's never used.

      cxl: Fix force unmapping mmaps of contexts allocated through the kernel 
api

      The cxl user api uses the address_space associated with the file when we
      need to force unmap all cxl mmap regions (e.g. on eeh, driver detach,
      etc). Currently, contexts allocated through the kernel api do not do
      this and instead skip the mmap invalidation, potentially allowing them
      to poke at the hardware after such an event, which may cause all sorts
      of trouble.

      This patch allocates an address_space for cxl contexts allocated through
      the kernel api so that the same invalidate path will for these contexts
      as well. We don't use the anonymous inode's address_space, as doing so
      could invalidate any mmaps of completely unrelated drivers using
      anonymous file descriptors.

      This patch also introduces a kernelapi flag, so we know when freeing the
      context if the address_space was allocated by us and needs to be freed.

      With tunneling, it is currently possible to get an IPv6 header and

      Most of this is net-next only. The third patch affects net, too, but it

      vxlan: do not receive IPv4 packets on IPv6 socket

      By default (subject to the sysctl settings), IPv6 sockets listen also for
      IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in
      packets received through an IPv6 socket.

      In addition, it's currently not possible to have both IPv4 and IPv6 vxlan
      tunnel on the same port (unless bindv6only sysctl is enabled), as it's not
      possible to create and bind both IPv4 and IPv6 vxlan interfaces and 
there's
      no way to specify both IPv4 and IPv6 remote/group IP addresses.

      Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not
      done globally in udp_tunnel, as l2tp and tipc seems to work okay when
      receiving IPv4 packets on IPv6 socket and people may rely on this 
behavior.
      The other tunnels (geneve and fou) do not support IPv6.

      fou: reject IPv6 config

      fou does not really support IPv6 encapsulation. After an UDP socket is
      created in fou_create, the encap_rcv callback is set either to 
fou_udp_recv
      or to gue_udp_recv. Both of those unconditionally assume that the received
      packet has an IPv4 header and access the data at network_header as it was 
an
      IPv4 header. This leads to IPv6 flow label being interpreted as IP packet
      length, etc.

      Disallow fou tunnel to be configured as IPv6 until real IPv6 support is
      added to fou.

      ip_tunnels: convert the mode field of ip_tunnel_info to flags

      The mode field holds a single bit of information only (whether the
      ip_tunnel_info struct is for rx or tx). Change the mode field to bit 
flags.
      This allows more mode flags to be added.

      ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc 
failure

      In PCM core, when hw_params() in each driver returns error, the state of
      PCM substream is kept as 'open'. In this case, current drivers for sound
      units on IEEE 1394 bus doesn't decrement substream counter in hw_free()
      correctly. This causes these drivers to keep streams even if not
      required.

      This commit fixes this bug. When snd_pcm_lib_alloc_vmalloc_buffer()
      fails, hw_params function in each driver returns without incrementing the
      counter.

      libnvdimm, pmem: direct map legacy pmem by default

      The expectation is that the legacy / non-standard pmem discovery method
      (e820 type-12) will only ever be used to describe small quantities of
      persistent memory.  Larger capacities will be described via the ACPI
      NFIT.  When "allocate struct page from pmem" support is added this default
      policy can be overridden by assigning a legacy pmem namespace to a pfn
      device, however this would be only be necessary if a platform used the
      legacy mechanism to define a very large range.

      libnvdimm, pmem: 'struct page' for pmem

      Enable the pmem driver to handle PFN device instances.  Attaching a pmem
      namespace to a pfn device triggers the driver to allocate and initialize
      struct page entries for pmem.  Memory capacity for this allocation comes
      exclusively from RAM for now which is suitable for low PMEM to RAM
      ratios.  This mechanism will be expanded later for setting an "allocate
      from PMEM" policy.

      libnvdimm, pfn: 'struct page' provider infrastructure

      Implement the base infrastructure for libnvdimm PFN devices. Similar to
      BTT devices they take a namespace as a backing device and layer
      functionality on top. In this case the functionality is reserving space
      for an array of 'struct page' entries to be handed out through
      pfn_to_page(). For now this is just the basic libnvdimm-device-model for
      configuring the base PFN device.

      As the namespace claiming mechanism for PFN devices is mostly identical
      to BTT devices drivers/nvdimm/claim.c is created to house the common
      bits.

      Staging: Add staging/rdma directory and update MAINTAINERS

      Create the rdma directory in the staging area for use as we deprecate
      some older drivers and as we bring in some new drivers that are in
      need of work.  Update the MAINTAINERS file so that updates to these
      files go to linux-rdma@xxxxxxxxxxxxxxxx  Expected lifespan of this
      directory is three releases for any deprecated drivers moved here
      and an unknown, but theoretically bounded amount of time for the new
      drivers as a new core RDMA transfer library needs to be written and
      the drivers modified to use it in order for them to move out of this

      RDMA/cma: fix IPv6 address resolution

      Resolving a link-local IPv6 address with an unspecified source address
      was broken by commit 5462eddd7a, which prevented the IPv6 stack from
      learning the scope id of the link-local IPv6 address, causing random
      failures as the IP stack chose a random link to resolve the address on.

      This commit 5462eddd7a made us bail out of cma_check_linklocal early if
      the address passed in was not an IPv6 link-local address. On the address
      resolution path, the address passed in is the source address; if the
      source address is the unspecified address, which is not link-local, we
      will bail out early.

      This is mostly correct, but if the destination address is a link-local
      address, then we will be following a link-local route, and we'll need to
      tell the IPv6 stack what the scope id of the destination address is.
      This used to be done by last line of cma_check_linklocal, which is
      skipped when bailing out early:

        dev_addr->bound_dev_if = sin6->sin6_scope_id;

      (In cma_bind_addr, the sin6_scope_id of the source address is set to the
      sin6_scope_id of the destination address, so this is correct)
      This line is required in turn for the following line, L279 of
      addr6_resolve, to actually inform the IPv6 stack of the scope id:

            fl6.flowi6_oif = addr->bound_dev_if;

      Since we can only know we are in this failure case when we have access
      to both the source IPv6 address and destination IPv6 address, we have to
      deal with this further up the stack. So detect this failure case in
      cma_bind_addr, and set bound_dev_if to the destination address scope id
      to correct it.

      IB/qib: Change lkey table allocation to support more MRs

      The lkey table is allocated with with a get_user_pages() with an
      order based on a number of index bits from a module parameter.

      The underlying kernel code cannot allocate that many contiguous pages.

      There is no reason the underlying memory needs to be physically
      contiguous.

      This patch:
      - switches the allocation/deallocation to vmalloc/vfree
      - caps the number of bits to 23 to insure at least 1 generation bit
        o this matches the module parameter description

      powercap / RAPL: disable the 2nd power limit properly

      Let rapl_unregister_powercap() disable the second power limit
      only if it exists.
      Intel64 SDM Vol.3 14.9 says that the package domain has it
      but neither the power plane domain nor the DRAM domain has it.

      tools: cpupower: Fix error when running cpupower monitor

      get_cpu_topology() tries to get topology info from all cpus by reading
      files in the topology sysfs dir. If a cpu is offlined, since it doesn't
      have topology dir, this function fails and returns -1. This causes
      functions relying on get_cpu_topology() to fail. For example-

      $ cpupower monitor
      Cannot read number of available processors

      Fix this by skipping fetching topology info for offline cpus.

      Netfilter updates for net-next

      The following patchset contains Netfilter/IPVS updates for your net-next 
tree.
      In sum, patches to address fallout from the previous round plus updates 
from
      the IPVS folks via Simon Horman, they are:

      1) Add a new scheduler to IPVS: The weighted overflow scheduling algorithm
         directs network connections to the server with the highest weight that 
is
         currently available and overflows to the next when active connections 
exceed
         the node's weight. From Raducu Deaconu.

      2) Fix locking ordering in IPVS, always take rtnl_lock in first place. 
Patch
         from Julian Anastasov.

      3) Allow to indicate the MTU to the IPVS in-kernel state sync daemon. From
         Julian Anastasov.

      4) Enhance multicast configuration for the IPVS state sync daemon. Also 
from
         Julian.

      5) Resolve sparse warnings in the nf_dup modules.

      6) Fix a linking problem when CONFIG_NF_DUP_IPV6 is not set.

      7) Add ICMP codes 5 and 6 to IPv6 REJECT target, they are more informative
         subsets of code 1. From Andreas Herz.

      8) Revert the jumpstack size calculation from mark_source_chains due to 
chain
         depth miscalculations, from Florian Westphal.

      9) Calm down more sparse warning around the Netfilter tree, again from 
Florian
         Westphal.

      netfilter: nfnetlink: work around wrong endianess in res_id field

      The convention in nfnetlink is to use network byte order in every header 
field
      as well as in the attribute payload. The initial version of the batching
      infrastructure assumes that res_id comes in host byte order though.

      The only client of the batching infrastructure is nf_tables, so let's add 
a
      workaround to address this inconsistency. We currently have 11 nfnetlink
      subsystems according to NFNL_SUBSYS_COUNT, so we can assume that the 
subsystem
      2560, ie. htons(10), will not be allocated anytime soon, so it can be an 
alias
      of nf_tables from the nfnetlink batching path when interpreting the res_id
      field.

      Based on original patch from Florian Westphal.

      sfc: Allow driver to cope with a lower number of VIs than it needs for RSS

      Previously, the driver would refuse to load if it couldn't secure
      enough VIs from the MC to fulfill its RSS requirements.
      This was causing probe to fail on later functions in
      configurations where we'd run out of VIs, such as having many
      VFs.

      This change allows the driver to load with fewer VIs, down to a
      minimum of 2. A warning will be printed saying that RSS
      requirements were not met, possibly affecting performance.

      efx->max_tx_channels needs to be set to avoid going down the
      failure path in efx_probe_nic() immediately in the loop after the
      probe() NIC-type function.
      Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack
      of VIs.

      IGMP: Inhibit reports for local multicast groups

      The range of addresses between 224.0.0.0 and 224.0.0.255 inclusive, is
      reserved for the use of routing protocols and other low-level topology
      discovery or maintenance protocols, such as gateway discovery and
      group membership reporting.  Multicast routers should not forward any
      multicast datagram with destination addresses in this range,
      regardless of its TTL.

      Currently, IGMP reports are generated for this reserved range of
      addresses even though a router will ignore this information since it
      has no purpose.  However, the presence of reserved group addresses in
      an IGMP membership report uses up network bandwidth and can also
      obscure addresses of interest when inspecting membership reports using
      packet inspection or debug messages.

      Although the RFCs for the various version of IGMP (e.g.RFC 3376 for
      v3) do not specify that the reserved addresses be excluded from
      membership reports, it should do no harm in doing so.  In particular
      there should be no adverse effect in any IGMP snooping functionality
      since 224.0.0.x is specifically excluded as per RFC 4541 (IGMP and MLD
      Snooping Switches Considerations) section 2.1.2. Data Forwarding
      Rules:

          2) Packets with a destination IP (DIP) address in the 224.0.0.X
             range which are not IGMP must be forwarded on all ports.

      IGMP reports for local multicast groups can now be optionally
      inhibited by means of a system control variable (by setting the value
      to zero) e.g.:
          echo 0 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports

      To retain backwards compatibility the previous behaviour is retained
      by default on system boot or reverted by setting the value back to
      non-zero e.g.:
          echo 1 >  /proc/sys/net/ipv4/igmp_link_local_mcast_reports

      r8169: Add software counter for multicast packages

      The multicast hardware counter on 8168/8111 chips is only 32 bit while the
      statistics in struct rtnl_link_stats64 are 64 bit.  Given that statistics
      are requested on an irregular basis, an overflow of the hardware counter
      can go unnoticed.  To count even very large numbers of multicast packets
      reliably, add a software counter and remove previously applied code to
      fill the multicast field requested by @rtl8169_get_stats64 with the values
      read from the rx_multicast hardware counter.

      scsi_dh: integrate into the core SCSI code

      Stop building scsi_dh as a separate module and integrate it fully into the
      core SCSI code with explicit callouts at bus scan time.  For now the
      callouts are placed at the same point as the old bus notifiers were 
called,
      but in the future we will be able to look at ALUA INQUIRY data earlier on.

      Note that this also means that the device handler modules need to be 
loaded
      by the time we scan the bus.  The next patches will add support for
      autoloading device handlers at bus scan time to make sure they are always
      loaded if they are enabled in the kernel config.

      Bluetooth: Fix SCO link type handling on connection complete

      Synchronous connections are initially created with type eSCO.
      Link manager may reject proposed link parameters, which triggers
      connection setup retry with a different set. Link type embedded
      in responses should be disregarded until Synchronous Connect Complete
      returns Success (0x00). Current code updates link type every time
      which creates an issue when link type changes to SCO and back to eSCO
      on further attepts.

      Issue happens with BlackBerry 9100 and 9700 with Intel WilkinsPeak
      on third connection setup attept

      Bluetooth: hci_intel: Add support for platform driver

      A platform device can be used to provide some specific resources in
      order to manage the controller. In this first patch we retrieve the
      reset gpio which is used to power on/off the controller.

      The main issue is to match the current tty with the correct pdev.
      In case of ACPI, we can easily find the right tty/pdev pair because
      they are both child of the same UART port.

      If controller is powered-on from the driver, we need to wait for a
      HCI boot event before being able to send any command.

      Bluetooth: hci_intel: Add Intel baudrate configuration support

      Implement the set_baudrate callback for hci_intel.
       - Controller requires a read Intel version command before updating
         its baudrate.
       - The operation consists in an async cmd since the controller does
         not respond at the same speed.
       - Wait 100ms to let the controller change its baudrate.
       - Clear RTS until we change our own UART speed

      Manage speed change in the setup function, we need to restore the oper
      speed once chip has booted on patched firmware.

      perf scripts python: Add new compaction-times script

      This patch creates a new script (compaction-times) to report time
      spent in mm compaction. It is possible to report times in nanoseconds
      (default) or microseconds (-u).

      The option -p will break down results by process id, -pv will further
      decompose by each compaction entry/exit.

      For each compaction entry/exit what is reported is controlled by the
      options:

      The default is to report all.

      Entries may be further filtered by pid, pid-range or comm (regex).

      The script is useful when analysing workloads that compact memory. The
      most common example will be THP allocations on systems with a lot of
      uptime that has fragmented memory.

      This is an example of using the script to analyse a thpscale from
      mmtests which deliberately fragments memory and allocates THP in 4
      separate threads

      thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macro

      vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses
      no_printk which produces no logging output but always
      evaluates arguments.

      Change the macro to surround the no_printk call with
        do { if (0) no_printk(...); } while (0)
      to avoid the unnecessary argument evaluations.

      regulator: core: use debug level print in regulator_check_drms

      When calling regulator_set_load, regulator_check_drms prints and returns
      an error if the regulator device's flag REGULATOR_CHANGE_DRMS isn't set.
      drms_uA_update, however, bails out without reporting an error.

      Replace the error print with a debug level print so that we don't get
      such prints when the underlying regulator doesn't support DRMS.

      This is because when extent cache is disable, extent_tree pointer in 
struct
      f2fs_inode_info should be NULL, but in f2fs_drop_largest_extent we access
      this NULL pointer directly without checking state of extent cache, then,
      the oops occurs. Let's fix it by checking state of extent cache before
      accessing.

      scripts: add stackdelta script

      This adds a simple perl script for reading two files as produced by
      the stackusage script and computing the changes in stack usage. For
      example:

      $ scripts/stackusage -o /tmp/old.su CC=gcc-4.7 -j8 fs/ext4/
      $ scripts/stackusage -o /tmp/new.su CC=gcc-5.0 -j8 fs/ext4/
      $ scripts/stackdelta /tmp/{old,new}.su | sort -k5,5g

      shows that gcc 5.0 generally produces less stack-hungry code than gcc
      4.7. Obviously, the script can also be used for measuring the effect
      of commits, .config tweaks or whatnot.

      scripts: add stackusage script

      The current checkstack.pl script has a few problems, stemming from the
      overly simplistic attempt at parsing objdump output with regular
      expressions: For example, on x86_64 it doesn't take the push
      instruction into account, making it consistently underestimate the
      real stack use, and it also doesn't capture stack pointer adjustments
      of exactly 128 bytes [1].

      Since newer gcc (>= 4.6) knows about -fstack-usage, we might as well
      take the information straight from the horse's mouth. This patch
      introduces scripts/stackusage, which is a simple wrapper for running
      make with KCFLAGS set to -fstack-usage. Example use is

      scripts/stackusage -o out.su -j8 lib/

      The script understands "-o foo" for writing to 'foo' and -h for a
      trivial help text; anything else is passed to make.

      Afterwards, we find all newly created .su files, massage them a
      little, sort by stack use and write the result to a single output
      file.

      Note that the function names printed by (at least) gcc 4.7 are
      sometimes useless. For example, the first three lines of out.su
      generated above are

      ./lib/decompress_bunzip2.c:155  get_next_block  448     static
      ./lib/decompress_unlzma.c:537   unlzma  336     static
      ./lib/vsprintf.c:616    8       304     static

      That function '8' is really the static symbol_string(), but it has
      been subject to 'interprocedural scalar replacement of aggregates', so
      its name in the object file is 'symbol_string.isra.8'. gcc 5.0 doesn't
      have this problem; it uses the full name as seen in the object file.

      [1] Since gcc encodes that by

      48 83 c4 80             add    $0xffffffffffffff80,%rsp

      and not

      48 81 ec 80 00 00 00    sub    $0x80,%rsp

      since -128 fits in an imm8.

      perf stat: Get correct cpu id for print_aggr

      print_aggr() fails to print per-core/per-socket statistics after commit
      582ec0829b3d ("perf stat: Fix per-socket output bug for uncore events")
      if events have differnt cpus. Because in print_aggr(), aggr_get_id needs
      index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be
      used to get aggregated id.

      Here is an example:

      Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has
      cpumask 0,18)

        $ perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core 
sleep 2

      Without this patch, it failes to get CPU 18 result.

         Performance counter stats for 'CPU(s) 0,18':

        S0-C0           1            7526851      cycles
        S0-C0           1               1.05 MiB  uncore_imc_0/cas_count_read/
        S1-C0           0      <not counted>      cycles
        S1-C0           0      <not counted> MiB  uncore_imc_0/cas_count_read/

      With this patch, it can get both CPU0 and CPU18 result.

         Performance counter stats for 'CPU(s) 0,18':

        S0-C0           1            6327768      cycles

      leds: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
      regardless of the mechanism that was used to register the device
      (i.e: OF or board code) and the table that is used later to match
      the driver with the device (i.e: I2C id table or OF match table).

      So drivers needs to export the I2C id table and this be built into
      the module or udev won't have the necessary information to autoload
      the needed driver module when the device is added.

      But this means that OF-only drivers needs to have both OF and I2C id
      tables that have to be kept in sync and also the dev node compatible
      manufacturer prefix is stripped when reporting the MODALIAS. Which can
      lead to issues if two vendors use the same I2C device name for example.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an SPI device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table even when
      is unused now to prevent breaking module loading when the core changes.

      leds:lp55xx: use the private data instead of updating I2C device platform 
data

      Currently, lp55xx_of_populate_pdata() allocates lp55xx_platform_data if
      it's null. And it parses the DT and copies values into the
      'client->dev.platform_data'. This may have architectural issue.
      Platform data is configurable through the DT or I2C board info inside the
      platform area. However, lp55xx common driver changes this configuration
      when it is loaded. So 'client->dev.platform_data' is not null anymore.
      Eventually, the driver initialization is not identical when it's unloaded
      and loaded again.
      The lp55xx common driver should use the private data, 'lp55xx_chip->pdata'
      instead of changing the original platform data.

      So, lp55xx_of_populate_pdata() is modified as follows.
      * Do not update 'dev->platform_data'. Return the pointer of new allocated
         lp55xx_platform_data. Then the driver points it to private data,
         'lp55xx_chip->pdata'.
      * Each lp55xx driver checks the pointer and handles an error case.

      Then, original platform data configuration will be kept regardless of
      loading or unloading the driver.
      The driver allocates the memory and copies them from the DT if it's NULL.
      After the driver is loaded again, 'client->dev.platform_data' is same as
      initial load, so the driver is initialized identically.

      leds: leds-ns2: handle can_sleep GPIOs

      On the board n090401 (Seagate NAS 4-Bay), some of the LEDs are handled
      by the leds-ns2 driver. This LEDs are connected to an I2C GPIO expander
      (PCA95554PW) which means that GPIO access may sleep. This patch makes
      leds-ns2 compatible with such GPIOs by using the *_cansleep() variant of
      the GPIO functions. As a drawback this functions can't be used safely in
      a timer context (with the timer LED trigger for example). To fix this
      issue, a workqueue mechanism (copied from the leds-gpio driver) is used.

      Note that this patch also updates slightly the ns2_led_sata_store
      function. The LED state is now retrieved from cached values instead of
      reading the GPIOs previously. This prevents ns2_led_sata_store from
      working with a stale LED state (which may happen when a delayed work
      is pending).

      leds: leds-ns2: move LED modes mapping outside of the driver

      On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO
      values to LED mode) is different from the one used on other boards
      supported by the leds-ns2 driver.

      With this patch the hardcoded mapping is removed from leds-ns2. Now,
      it must be defined either in the platform data (if an old-fashion board
      setup file is used) or in the DT node. In order to allow the later, this
      patch also introduces a modes-map property for the leds-ns2 DT binding.

      MIPS: CPS: use 32b accesses to GCRs

      Commit b677bc03d757 ("MIPS: cps-vec: Use macros for various arithmetics
      and memory operations") replaced various load & store instructions
      through cps-vec.S with the PTR_L & PTR_S macros. However it was somewhat
      overzealous in doing so for CM GCR accesses, since the bit width of the
      CM doesn't necessarily match that of the CPU. The registers accessed
      (GCR_CL_COHERENCE & GCR_CL_ID) should be safe to simply always access
      using 32b instructions, so do so in order to avoid issues when using a
      32b CM with a 64b CPU.

      x86/mm/mtrr: Remove kernel internal MTRR interfaces: unexport mtrr_add() 
and mtrr_del()

      The effort to replace mtrr_add() with architecture agnostic
      arch_phys_wc_add() is complete, this will ensure write-combining
      implementations (PAT on x86) is taken advantage instead of using
      MTRR. With the effort done now, hide direct MTRR access for
      drivers.

      The legacy user-space /proc/mtrr ABI is not affected.

      Update x86 documentation on MTRR to reflect the completion of
      the phasing out of direct access to MTRR, also add a note on
      platform firmware code use of MTRRs based on the obituary
      discussion of MTRRs on Linux [0].

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Add support for using several Intel PT features (CYC, MTC packets), 
the
          relevant documentation was updated: 
tools/perf/Documentation/intel-pt.txt,
          briefly describing those packets, its purposes, how to configure them 
in
          the event config terms and relevant external documentation for further
          reading. (Adrian Hunter)

        - Introduce support for probing at an absolute address, for user and 
kernel
          'perf probe's, useful when one have the symbol maps on a developer 
machine
          but not on an embedded system. (Wang Nan)

        - Fix 'perf probe' list results when a symbol can't be found or the
          address is zero and when an offset is provided without a function 
(Wang Nan)

        - Do not print '0x (null)' in uprobes when offset is zero (Wang Nan)

        - Clear the progress bar at the end of a ordered_events flush, fixing
          an UI artifact when, after ordering the events the screen doesn't get
          completely redraw, for instance, when an error window covers just the
          center of the screen and waits for user input. (Arnaldo Carvalho de 
Melo)

        - Fix 'annotate' segfault by resetting the dso find_symbol cache when 
removing
          symbols. (Arnaldo Carvalho de Melo)

      Infrastructure changes:

        - Allow duplicate objects in the object list, just like it is possible 
to have
          things like this, in the kernel:

            drivers/Makefile:obj-$(CONFIG_PCI)        += usb/
            drivers/Makefile:obj-$(CONFIG_USB_GADGET) += usb/

          (Jiri Olsa)

        - Fix Intel PT 'instructions' sample period. (Adrian Hunter)

        - Prevent segfault when reading probe point with absolute address. 
(Wang Nan)

      Build fixes:

        - Fix tarball build broken by pt/bts. (Adrian Hunter)

        - Remove export.h from MANIFEST, fixing the perf tarball make target.

      s390/io: Add pci_iomap_wc() and pci_iomap_wc_range()

      The following commit:

        1b3d4200c1e0 ("PCI: Add pci_iomap_wc() variants")

      Introduced pci_iomap_wc() variants but broke the s390 build,
      because s390 requires its own implementation of pcio_iomap*()
      calls.

      The reason for that is that:

        "BAR spaces are not disjunctive on s390 so we need the bar
         parameter of pci_iomap to find the corresponding device
         and create the mapping cookie"

      so it has its own lookup/lock solution and it does not include
      asm-generic/pci_iomap.h.

      Since it currenty maps ioremap_wc() to ioremap_nocache() and
      that's the architecture default we can easily just map the wc
      calls to the default calls as well.

      xfs: return errors from partial I/O failures to files

      There is an issue with xfs's error reporting in some cases of I/O 
partially
      failing and partially succeeding. Calls like fsync() can report success 
even
      though not all I/O was successful in partial-failure cases such as one 
disk of
      a RAID0 array being offline.

      The issue can occur when there are more than one bio per xfs_ioend struct.
      Each call to xfs_end_bio() for a bio completing will write a value to
      ioend->io_error.  If a successful bio completes after any failed bio, no
      error is reported do to it writing 0 over the error code set by any 
failed bio.
      The I/O error information is now lost and when the ioend is completed
      only success is reported back up the filesystem stack.

      xfs_end_bio() should only set ioend->io_error in the case of BIO_UPTODATE
      being clear.  ioend->io_error is initialized to 0 at allocation so only 
needs
      to be updated by a failed bio. Also check that ioend->io_error is 0 so 
that
      the first error reported will be the error code returned.

      powerpc/eeh: Fix fenced PHB caused by eeh_slot_error_detail()

      The config space of some PCI devices can't be accessed when their
      PEs are in frozen state. Otherwise, fenced PHB might be seen.
      Those PEs are identified with flag EEH_PE_CFG_RESTRICTED, meaing
      EEH_PE_CFG_BLOCKED is set automatically when the PE is put to
      frozen state (EEH_PE_ISOLATED). eeh_slot_error_detail() restores
      PCI device BARs with eeh_pe_restore_bars(), which then calls
      eeh_ops->restore_config() to reinitialize the PCI device in
      (OPAL) firmware. eeh_ops->restore_config() produces PCI config
      access that causes fenced PHB. The problem was reported on below
      adapter:

         0001:01:00.0 0200: 14e4:168e (rev 10)
         0001:01:00.0 Ethernet controller: Broadcom Corporation \
                      NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)

      This fixes the issue by skipping eeh_pe_restore_bars() in
      eeh_slot_error_detail() when EEH_PE_CFG_BLOCKED is set for the PE.

      Merge branch 'linux-4.3' of 
git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next

      Rather large pull request this time around, due to the long-pending
      cleanup of the kernel driver being here.  There's a stupidly large
      number of commits for that, as I wanted to have the series be
      bisectable at a fairly fine-grained level.  That said, a very large
      portion of the churn in the rework was automated, and a very large
      number of boards from right across the whole range we support have
      been tested.  I'm fairly confident there shouldn't be (too many)
      issues from this.

      Beyond correcting some not-so-great design decisions and making the
      code a lot easier to work with, there's not much exciting (lower
      memory usage, GPU VM should be a lot faster, etc) to be gained by the
      end-user as a result of the cleanup, it mostly lays the groundwork for
      future improvements.

      A big thanks goes to Alexandre Courbot for testing/debugging the GK20A
      codepaths for me :)

      Highlights:
      - A heap of perfmon work, providing a more useful userspace interface
      and specifying counters for a bunch of boards
      - Support for GT200 reclocking + other misc pm improvements
      - Initial patches towards supporting GM20B (Tegra X1)
      - Maxwell DisplayPort fixes
      - Cleanup of the kernel driver
      - The usual collection of random fixes

      drm/nouveau/mmu: protect each vm with its own mutex

      An upcoming commit requires being able to modify the PRAMIN BAR page
      tables while already holding the MMU subdev mutex.

      To solve this issue, each VM has been given its own mutex.  As a nice
      side-effect, this also allows separate VMs to be updated concurrently.

      drm/nouveau/nvif: simplify and tidy library interfaces

      A variety of tweaks to the NVIF library interfaces, mostly ripping out
      things that turned out to be not so useful.

      - Removed refcounting from nvif_object, callers are expected to not be
        stupid instead.
      - nvif_client is directly reachable from anything derived from 
nvif_object,
        removing the need for heuristics to locate it
      - _new() versions of interfaces, that allocate memory for the object
        they construct, have been removed.  The vast majority of callers used
        the embedded _init() interfaces.
      - No longer storing constructor arguments (and the data returned from
        nvkm) inside nvif_object, it's more or less unused and just wastes
        memory.

      drm/nouveau/device: simplify subdev construction

      Replaces the piece-by-piece (in response to NV_DEVICE ctor args) device
      contruction with a once-off all-or-nothing approach, eliminating some
      tricky refcounting issues.  The partial device init capability was only
      required by some tools, and has been moved to probe time instead.

      Temporarily removes a workaround for some boards where we need to fiddle
      with AGP registers before executing the DEVINIT scripts.  A later commit
      in this series reinstates it.

      drm/nouveau/gpuobj: type-safe accessor macros

      These require an explicit struct nvkm_gpuobj pointer, unlike the previous
      macros which take a void *, and work with any nvkm_object.

      New semantics require acquiring/releasing a gpuobj before accessing them,
      which will be made use of in later patches to greatly reduce the overhead
      of accesses, particularly when a direct mmio mapping of the object is not
      available (suspend/resume, out of ioremap() space, and on GK20A).

      drm/nouveau/core: type-safe printk macros

      These require an explicit pointers to nvkm_object/nvkm_subdev/nvkm_device,
      depending on which macros are used.  This is unlike the previous macros
      which take a void *, and work for anything derived from nvkm_object (by
      way of some awful heuristics).

      The output will be a bit confused until everything has been transitioned,
      as the logging format used is a more standard style that previously.

      In addition, usage of pr_cont(), which doesn't work correctly with the
      dev_*() printk functions (and was potentially racy to begin with), will
      be replaced.

      drm/nouveau/tmr: type-safe PTIMER-based delay/wait macros

      These require an explicit struct nvkm_device pointer, unlike the previous
      macros which take a void *, and work for (almost) anything derived from
      nvkm_object by using some heuristics.

      These macros are more general than the previous ones, and can be used to
      handle PTIMER-based busy-waits (will be used in later devinit fixes) as
      well as more complicated wait conditions.

      drm/nouveau/device: include core/device.h automatically for 
subdevs/engines

      Pretty much every subdev/engine is going to need access to nvkm_device
      shortly to touch registers and/or output messages.

      The odd placement of the includes is necessary to work around some
      inter-dependencies that currently exist.  This will be fixed later.

      drm/nouveau/gr/gk20a: use same initialization sequence as nvgpu

      GK20A's initialization was based on GK104, but differences exist in the
      way the initial context is built and the initialization process itself.

      This patch follows the same initialization sequence as nvgpu performs
      to avoid bad surprises. Since the register bundles initialization also
      differ considerably from GK104, the register packs are now loaded from
      firmware files, again similarly to what is done with nvgpu.

      drm/nouveau/pm: allow to configure domains instead of simple counters

      Configuring counters from the userspace require the kernel to handle some
      logic related to performance counters. Basically, it has to find a free
      slot to assign a counter, to handle extra counting modes like B4/B6 and it
      must return and error when it can't configure a counter.

      In my opinion, the kernel should not handle all of that logic but it
      should only write the configuration sent by the userspace without
      checking anything. In other words, it should overwrite the configuration
      even if it's already counting and do not return any errors.

      This patch allows the userspace to configure a domain instead of
      separate counters. This has the advantage to move all of the logic to
      the userspace.

      powerpc/pseries: Fix corrupted pdn list

      Commit cca87d30 ("powerpc/pci: Refactor pci_dn") introduced pdn
      list for SRIOV VFs. It means the pdn is be put into the child list
      of its parent pdn when the pdn is created. When doing PCI hot
      unplugging on pSeries, the PCI device node as well as its pdn are
      released through procfs entry "powerpc/ofdt". Some one else grabs
      the memory chunk of the pdn and update it accordingly. At the same
      time, the pdn is still tracked in the child list of parent pdn. It
      leads to corrupted child list in the parent pdn.

      This fixes above issue by removing the pdn from the child list of
      its parent pdn when the device node is detached from the system.
      Note the pdn is free'd when the device node is released if the
      device node is dynamic one. Otherwise, the device node as well
      as the pdn won't be released.

       "This is a libnvdimm ABI fixup.

        I pushed back on this change quite hard given the late date, that it
        appears to be purely cosmetic, sysfs is not necessarily meant to be a
        user friendly UI, and the kernel interprets the reversed polarity of
        the ACPI_NFIT_MEM_ARMED flag correctly.  When this flag is set, the
        energy source of an NVDIMM is not armed and any new writes to the DIMM
        may not be preserved.

        However, Bob Moore warned me that it is important to get these things
        named correctly wherever they appear otherwise we run the risk of a
        less than cautious firmware engineer implementing the polarity the
        wrong way.  Once a mistake like that escapes into production platforms
        the flag becomes useless and we need to move to a new bit position.

        Bob has agreed to take a change through ACPICA to rename
        ACPI_NFIT_MEM_ARMED to ACPI_NFIT_MEM_NOT_ARMED, and the patch below
        from Toshi brings the sysfs representation of these flags in line with
        their respective polarities.

        Please pull for 4.2 as this is the first kernel to expose the ACPI
        NFIT sysfs representation, and this is likely a kernel that firmware
        developers will be using for checking out their NVDIMM enabling"

      Phil Sutter says:

      ====================
      fixup IFF_NO_QUEUE conversion

      This series serves two purposes:

      On one hand it fixes a quite embarrassing bug around the warning I added 
for
      drivers still setting tx_queue_len = 0 to achieve noqueue operation. It 
turned
      out to be quite useless as due to using alloc_netdev(), many in-kernel 
drivers
      fell into the trap by accident, as well. Instead this place serves pretty 
well
      as a sanitizing point to set IFF_NO_QUEUE for drivers not initializing
      tx_queue_len, which in turn allows to drop all special treatment of the 
latter
      being zero since that can not happen anymore without IFF_NO_QUEUE being 
set.

      On the other hand, it provides a better solution for Eric Dumazet's 
concern
      regarding how to assign noqueue to an interface which does not default to 
it
      already. In order to make this possible, noqueue is being registered so 
users
      can 'tc qd add dev eth0 root noqueue'. In addition, it resolves the ugly
      situation of 'tc qd show' not showing noqueue. Finally, the former changes
      allow for some code cleanup.

      sctp: donot reset the overall_error_count in SHUTDOWN_RECEIVE state

      Commit f8d960524328 ("sctp: Enforce retransmission limit during shutdown")
      fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by 
not
      resetting the association overall_error_count.  This allowed the 
association
      to better enforce assoc.max_retrans limit.

      However, the same issue still exists when the association is in 
SHUTDOWN_RECEIVED
      state.  In this state, HB-ACKs will continue to reset the 
overall_error_count
      for the association would extend the lifetime of association 
unnecessarily.

      This patch solves this by resetting the overall_error_count whenever the 
current
      state is small then SCTP_STATE_SHUTDOWN_PENDING.  As a small side-effect, 
we
      end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and 
SCTP_STATE_SHUTDOWN_SENT
      states, but they are not really impacted because we disable Heartbeats in 
those
      states.

      For local process's rlimit, it should be checked by nfs client.

      The same, CIFS also call inode_change_ok checking rlimit at its client
      in cifs_setattr_nounix() and cifs_setattr_unix().

      x86, pmem: clarify that ARCH_HAS_PMEM_API implies PMEM mapped WB

      Given that a write-back (WB) mapping plus non-temporal stores is
      expected to be the most efficient way to access PMEM, update the
      definition of ARCH_HAS_PMEM_API to imply arch support for
      WB-mapped-PMEM.  This is needed as a pre-requisite for adding PMEM to
      the direct map and mapping it with struct page.

      The above clarification for X86_64 means that memcpy_to_pmem() is
      permitted to use the non-temporal arch_memcpy_to_pmem() rather than
      needlessly fall back to default_memcpy_to_pmem() when the pcommit
      instruction is not available.  When arch_memcpy_to_pmem() is not
      guaranteed to flush writes out of cache, i.e. on older X86_32
      implementations where non-temporal stores may just dirty cache,
      ARCH_HAS_PMEM_API is simply disabled.

      The default fall back for persistent memory handling remains.  Namely,
      map it with the WT (write-through) cache-type and hope for the best.

      arch_has_pmem_api() is updated to only indicate whether the arch
      provides the proper helpers to meet the minimum "writes are visible
      outside the cache hierarchy after memcpy_to_pmem() + wmb_pmem()".  Code
      that cares whether wmb_pmem() actually flushes writes to pmem must now
      call arch_has_wmb_pmem() directly.

      mm: ZONE_DEVICE for "device memory"

      While pmem is usable as a block device or via DAX mappings to userspace
      there are several usage scenarios that can not target pmem due to its
      lack of struct page coverage. In preparation for "hot plugging" pmem
      into the vmemmap add ZONE_DEVICE as a new zone to tag these pages
      separately from the ones that are subject to standard page allocations.
      Importantly "device memory" can be removed at will by userspace
      unbinding the driver of the device.

      Having a separate zone prevents allocation and otherwise marks these
      pages that are distinct from typical uniform memory.  Device memory has
      different lifetime and performance characteristics than RAM.  However,
      since we have run out of ZONES_SHIFT bits this functionality currently
      depends on sacrificing ZONE_DMA.

      bridge: fdb: rearrange net_bridge_fdb_entry

      While looking into fixing the local entries scalability issue I noticed
      that the structure is badly arranged because vlan_id would fall in a
      second cache line while keeping rcu which is used only when deleting
      in the first, so re-arrange the structure and push rcu to the end so we
      can get 16 bytes which can be used for other fields (by pushing rcu
      fully in the second 64 byte chunk). With this change all the core
      necessary information when doing fdb lookups will be available in a
      single cache line.

      nd_blk: change aperture mapping from WC to WB

      This should result in a pretty sizeable performance gain for reads.  For
      rough comparison I did some simple read testing using PMEM to compare
      reads of write combining (WC) mappings vs write-back (WB).  This was
      done on a random lab machine.

      PMEM reads from a write combining mapping:
        # dd of=/dev/null if=/dev/pmem0 bs=4096 count=100000
        100000+0 records in
        100000+0 records out
        409600000 bytes (410 MB) copied, 9.2855 s, 44.1 MB/s

      PMEM reads from a write-back mapping:
        # dd of=/dev/null if=/dev/pmem0 bs=4096 count=1000000
        1000000+0 records in
        1000000+0 records out
        4096000000 bytes (4.1 GB) copied, 3.44034 s, 1.2 GB/s

      To be able to safely support a write-back aperture I needed to add
      support for the "read flush" _DSM flag, as outlined in the DSM spec:

      http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf

      This flag tells the ND BLK driver that it needs to flush the cache lines
      associated with the aperture after the aperture is moved but before any
      new data is read.  This ensures that any stale cache lines from the
      previous contents of the aperture will be discarded from the processor
      cache, and the new data will be read properly from the DIMM.  We know
      that the cache lines are clean and will be discarded without any
      writeback because either a) the previous aperture operation was a read,
      and we never modified the contents of the aperture, or b) the previous
      aperture operation was a write and we must have written back the dirtied
      contents of the aperture to the DIMM before the I/O was completed.

      In order to add support for the "read flush" flag I needed to add a
      generic routine to invalidate cache lines, mmio_flush_range().  This is
      protected by the ARCH_HAS_MMIO_FLUSH Kconfig variable, and is currently
      only supported on x86.

      mlxsw: Make mailboxes 4KB aligned

      The HW-SW contract requires mailboxes passed to the firmware to be 4KB
      aligned. Previously, these mailboxes were mapped using streaming DMA
      routines, which do not guarantee the bus addresses to be 4KB aligned.
      Under certain conditions this constraint was indeed violated and errors
      were observed.

      By using consistent DMA mapping routines together with a mailbox size of
      4KB we are guaranteed not to violate the constraint.

      zero so memcmpshow() will show the wrong offset in the print message.
      To fix this we introduce a new function memcmpshowoffset() which takes
      offset as a parameter and displays the right offset and use it in
      the case where offset is non zero.

      The old memcmpshow() functionality is preserved by converting it into
      a macro with offset preset to 0.

      that and use this info directly.

      This also fixes possible issues that could happen when non-master device

      Usually an skb does not have up to MAX_SKB_FRAGS frags. So no need to

      - during xmit, it could be inferred from nr_frags and can_push.
      - for small receive buffer, it will also be 2.

      Geneve: Add support for tunnel metadata mode

      Following patches adds support for Geneve tunnel metadata
      mode. OVS can make use of Geneve net-device with tunnel
      metadata API from kernel.

      This also allows us to consolidate Geneve implementation
      from two kernel modules geneve_core and geneve to single
      geneve module. geneve_core module was targeted to share
      Geneve encap and decap code between Geneve netdevice and
      OVS Geneve tunnel implementation, Since OVS no longer
      needs these API, Geneve code can be consolidated into
      single geneve module.

      v3-v4:
      - Drop NETIF_F_NETNS_LOCAL feature.
      - Fix geneve device newlink check

      v2-v3:
      - make tunnel medata device and regular device mutually exclusive.
      - Fix Kconfig dependency for Geneve.
      - Fix dst-port netlink encoding.
      - drop changelink patch.

      v1-v2:
      - Replaced per hash table tunnel pointer (metadata enabled) with flag.
      - Added support for changelink.
      - Improve geneve device route lookup with more parameters.

      selftests/zram: Adding zram tests

      zram: Compressed RAM based block devices
      ----------------------------------------
      The zram module creates RAM based block devices named /dev/zram<id>
      (<id> = 0, 1, ...). Pages written to these disks are compressed and stored
      in memory itself. These disks allow very fast I/O and compression provides
      good amounts of memory savings. Some of the usecases include /tmp storage,
      use as swap disks, various caches under /var and maybe many more :)

      Statistics for individual zram devices are exported through sysfs nodes at
      /sys/block/zram<id>/

      This patch is to validate the zram functionality. Test interacts with

      Documentation/Changes: Now need OpenSSL devel packages for module signing

      The module signing script (sign-file) used to be a wrapper around the
      openssl program.  It has now been replaced by a C program that uses the
      crypto library from the OpenSSL package meaning that the OpenSSL devel
      packages are necessary to provide the devel library link and the header
      files.

      This would be openssl-devel on Fedora and libssl-dev on Debian.

      Commit 62ee783bf1f8 ("smsc911x: Fix crash seen if neither ACPI nor OF is

      device_get_phy_mode() and bails out if there is an error. Unfortunately,
      there are configurations where no phy is configured. Those configurations
      now fail.

      To fix the problem, accept error returns from device_get_phy_mode(),
      and use the return value from device_property_read_u32() to determine
      if there is a suitable firmware interface to read the configuration.

      net: sched: consolidate tc_classify{,_compat}

      For classifiers getting invoked via tc_classify(), we always need an
      extra function call into tc_classify_compat(), as both are being
      exported as symbols and tc_classify() itself doesn't do much except
      handling of reclassifications when tp->classify() returned with
      TC_ACT_RECLASSIFY.

      CBQ and ATM are the only qdiscs that directly call into 
tc_classify_compat(),
      all others use tc_classify(). When tc actions are being configured
      out in the kernel, tc_classify() effectively does nothing besides
      delegating.

      We could spare this layer and consolidate both functions. pktgen on
      single CPU constantly pushing skbs directly into the netif_receive_skb()
      path with a dummy classifier on ingress qdisc attached, improves
      slightly from 22.3Mpps to 23.1Mpps.

      Intel Wired LAN Driver Updates 2015-08-26

      This series contains updates to i40e and i40evf only.

      Anjali provides a fix for i40e where the part is not receiving multicast
      or VLAN tagged packets when in promiscuous mode.  This can occur when a
      software bridge is created on top of the device.  Fixed the legacy and MSI
      interrupt mode in the driver, which was non-existent before since we
      were assuming MSIX was the only mode that the driver ran in.  Fixed the
      i40evf driver, where the wrong defines were getting used in the VF
      driver.

      Mitch fixes a sparse warning about comparing __le16 to u16 so use
      le16_to_cpu() to resolve the warning.  Also fixed a dyslexic spelling
      of invalid.

      Shannon adds port.crc_errors to receive CRC error counter, since it
      is a receive counter.

      Catherine provides a fix to move the stopping of the service task and
      flow director to i40e_shutdown() instead of i40e_suspend().

      Greg fixes the ethtool offline diagnostic with netqueues, which just need
      to be treated the same as virtual functions when someone wants to run the
      ethtool offline diagnostic test.  Also fixed up code comments for the
      i40e ethtool diagnostic test function.  Cleans up redundant and unneeded
      messages, since the kernel notifies all VXLAN capable registered drivers,
      so no need to log this.

      Neerav adds the ability to update statistics per VEB per traffic class
      and dump it via ethtool.

      Jingjing adds support for virtual channel offload to support receive
      polling mode in the VF driver.

      v2: dropped patch which added helper functions into a header, feedback 
from
          David Miller was to make the functions constant to reduce the driver
          footprint, so remove the patch while Anjali works on making the 
requested
          changes.

      sctp: asconf's process should verify address parameter is in the beginning

      in sctp_process_asconf(), we get address parameter from the beginning of
      the addip params. but we never check if it's really there. if the addr
      param is not there, it still can pass sctp_verify_asconf(), then to be
      handled by sctp_process_asconf(), it will not be safe.

      so add a code in sctp_verify_asconf() to check the address parameter is in
      the beginning, or return false to send abort.

      note that this can also detect multiple address parameters, and reject it.

      OVS conntrack support

      The goal of this series is to allow OVS to send packets through the Linux
      kernel connection tracker, and subsequently match on fields populated by
      conntrack. This functionality is enabled through a new
      CONFIG_OPENVSWITCH_CONNTRACK option.

      This version addresses the feedback from v5, primarily checking the 
behaviour
      is correct with different configurations such as disabling
      CONFIG_OPENVSWITCH_CONNTRACK or disabling individual conntrack features 
like
      connlabels.

      openvswitch: Allow attaching helpers to ct action

      Add support for using conntrack helpers to assist protocol detection.
      The new OVS_CT_ATTR_HELPER attribute of the CT action specifies a helper
      to be used for this connection. If no helper is specified, then helpers
      will be automatically applied as per the sysctl configuration of
      net.netfilter.nf_conntrack_helper.

      The helper may be specified as part of the conntrack action, eg:
      ct(helper=ftp). Initial packets for related connections should be
      committed to allow later packets for the flow to be considered
      established.

      Example ovs-ofctl flows allowing FTP connections from ports 1->2:
      in_port=1,tcp,action=ct(helper=ftp,commit),2
      in_port=2,tcp,ct_state=-trk,action=ct(recirc)
      in_port=2,tcp,ct_state=+trk-new+est,action=1

      openvswitch: Add conntrack action

      Expose the kernel connection tracker via OVS. Userspace components can
      make use of the CT action to populate the connection state (ct_state)
      field for a flow. This state can be subsequently matched.

      Exposed connection states are OVS_CS_F_*:
      - NEW (0x01) - Beginning of a new connection.
      - ESTABLISHED (0x02) - Part of an existing connection.
      - RELATED (0x04) - Related to an established connection.
      - INVALID (0x20) - Could not track the connection for this packet.
      - REPLY_DIR (0x40) - This packet is in the reply direction for the flow.
      - TRACKED (0x80) - This packet has been sent through conntrack.

      When the CT action is executed by itself, it will send the packet
      through the connection tracker and populate the ct_state field with one
      or more of the connection state flags above. The CT action will always
      set the TRACKED bit.

      When the COMMIT flag is passed to the conntrack action, this specifies
      that information about the connection should be stored. This allows
      subsequent packets for the same (or related) connections to be
      correlated with this connection. Sending subsequent packets for the
      connection through conntrack allows the connection tracker to consider
      the packets as ESTABLISHED, RELATED, and/or REPLY_DIR.

      The CT action may optionally take a zone to track the flow within. This
      allows connections with the same 5-tuple to be kept logically separate
      from connections in other zones. If the zone is specified, then the
      "ct_zone" match field will be subsequently populated with the zone id.

      IP fragments are handled by transparently assembling them as part of the
      CT action. The maximum received unit (MRU) size is tracked so that
      refragmentation can occur during output.

      IP frag handling contributed by Andy Zhou.

      Based on original design by Justin Pettit.

      nfit: Clarify memory device state flags strings

      ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines
      NVDIMM status as follows.  These bits indicate multiple info,
      such as failures, pending event, and capability.

        Bit [0] set to 1 to indicate that the previous SAVE to the
        Memory Device failed.
        Bit [1] set to 1 to indicate that the last RESTORE from the
        Memory Device failed.
        Bit [2] set to 1 to indicate that platform flush of data to
        Memory Device failed. As a result, the restored data content
        may be inconsistent even if SAVE and RESTORE do not indicate

      bgmac: support up to 3 cores (devices) on a bus

      Broadcom buses may have more than 1 Ethernet device. This is used e.g.
      to have few interfaces connected to different switch ports. So far we
      saw chipsets with only 2 devices (e.g. BCM4706) but recent ones have
      up to 3 (e.g. Netgear R8000 uses 3rd interface for most of switch
      traffic, lower interfaces are for some kind of offloading).

      batman-adv: don't access unregistered net_device object

      In batadv_hardif_disable_interface() there is a call to
      batadv_softif_destroy_sysfs() which in turns invokes
      unregister_netdevice() on the soft_iface.
      After this point we cannot rely on the soft_iface object
      anymore because it might get free'd by the netdev periodic
      routine at any time.

      For this reason the netdev_upper_dev_unlink(.., soft_iface) call
      is moved before the invocation of batadv_softif_destroy_sysfs() so
      that we can be sure that the soft_iface object is still valid.

      mpt3sas: When device is blocked followed by unblock fails, unfreeze the 
I/Os

      Issue: When the disks are getting discovered and assigned device
      handles by the kernel, a device block followed by an unblock
      (due to broadcast primitives) issued by the driver is
      interspersed by the kernel changing the state of the device.
      Therefore the unblock by the driver results in a no operation
      within the kernel API.

      To fix this one, the below patch checks the return of the unblock API
      and performs a block followed by an unblock to unfreeze the block
      layer's I/O queue. Sufficient checks and prints are also added in the
      driver to identify this condition caused by the kernel.

Layer(SML),

      For any SCSI command, if the driver receives
      IOC status = SCSI_IOC_TERMINATED and log info = 0x32010081 then
      that command will be completed with DID_RESET host status.

      The definition of this log info value is
      "Virtual IO has failed and has to be retried".

      Firmware will provide this log info value with IOC Status
      "SCSI_IOC_TERMINATED", whenever a drive (with is a part of a volume)
      is pulled and pushed back within some minimal delay.
      With this log info value, firmware informs the driver to retry the
      failed IO command infinite times, so to provide some time for the
      firmware to discover the reinserted drive successfully instated of
      just retrying failed command for five times(doesn't giving enough
      time for firmware to complete the drive discovery) and failing the
      IO permanently even though drive came back successfully.

      mpt3sas: Provides the physical location of sas drives

      This Patch will provide more details of the devices such as slot number,
      enclosure logical id, enclosure level & connector name in the following
      scenarios,

      - When end device is added in the topology,

      - When the end device is removed from the setup,

      - When the SCSI mid layer issues TASK ABORT/ DEVICE RESET/ TARGET RESET 
during
        error handling,

      - When any command to the device fails with Sense key Hardware error or 
Medium
        error or Unit Attention,

      - When firmware returns device error or device not ready status for the 
end
        device,

      - When a Predicted fault is detected on an end device.

      This information can be used by the user to identify the location of the
      desired drive in the topology.

      Driver will get these information by reading the sas device page0.

      mpt3sas: Don't block the drive when drive addition under the control of 
SML

      During hot-plugging of a disk(having a flaky link), the disk addition
      stops and any further disk addition or removal doesn't happen on that
      controller.

      This is because, when driver receives DELAY_NOT_RESPONDING event for a 
disk
      while it is undergoing addition at the SCSI Transport layer, the driver
      would block the I/O to that disk resulting in a deadlock. i.e the disk
      addition work couldn't be completed at the SCSI Transport Layer as it
      can't send any I/Os (such as Inquiry, Report LUNs etc) to the disk as
      I/Os are blocked to this drive. Also any subsequent device removal
      (TARGET_NOT_RESPONDING) or link update(RC_PHY_CHANGED) event couldn't be
      processed as they are in the queue to get processed after disk addition
      event.

      Description of Change:
      Don't block the drive when drive addition is under the control of SML.
      So that SML won't be blocked of issuing the device dicovery commands
      (such as Inquiry, Report LUNs etc).

      mpt3sas: Added Combined Reply Queue feature to extend up-to 96 MSIX 
vector support

      In this patch, increased the number of MSIX vector support for SAS3 C0 
HBAs to
      up-to 96.

      Following are changes that are done in this patch

      1. This feature is enabled only for SAS3 C0 and higher revision cards and 
also
      only when reply post free queue count is greater than 8.

      2. To support this feature 12 SupplementalReplyPostHostIndex system 
interfaces
      are used. MSI-X index numbered from 0 to 7 use the first
      SupplementalReplyPostHostIndex system interface to update its 
corresponding
      ReplyPostHostIndex values, MSI-X index numbered from 8 to 15 will use the
      second SupplementalReplyPostHostIndex system interface and so on. These 12
      SuppementalReplyPostHostIndex system interfaces address are saved in the 
array
      replyPostRegisterIndex[].

      3. As each SupplementalReplyPostHostIndex register supports 8 MSI-X
      vectors. So MSIxIndex field in these register must contain a value 
between 0
      and 7.

      4. After processing the reply descriptors from a reply post free queues 
then
      update the new reply post host index value in ReplyPostHostIndex field and
      (msix_index mod 8) value in MSIxIndex field of 
SupplementalReplyPostHostIndex
      register. The Address of this SupplementalReplyPostHostIndex register is
      retrived from (msix_index/8)th entry of replyPostRegisterIndex[] array.

      arm64: KVM: Fix host crash when injecting a fault into a 32bit guest

      When injecting a fault into a misbehaving 32bit guest, it seems
      rather idiotic to also inject a 64bit fault that is only going
      to corrupt the guest state. This leads to a situation where we
      perform an illegal exception return at EL2 causing the host
      to crash instead of killing the guest.

      Just fix the stupid bug that has been there from day 1.

      irqchip/GIC: Convert to EOImode == 1

      So far, GICv2 has been used with EOImode == 0. The effect of this
      mode is to perform the priority drop and the deactivation of the
      interrupt at the same time.

      While this works perfectly for Linux (we only have a single priority),
      it causes issues when an interrupt is forwarded to a guest, and when
      we want the guest to perform the EOI itself.

      For this case, the GIC architecture provides EOImode == 1, where:
      - A write to the EOI register drops the priority of the interrupt
        and leaves it active. Other interrupts at the same priority level
        can now be taken, but the active interrupt cannot be taken again
      - A write to the DIR marks the interrupt as inactive, meaning it can
        now be taken again.

      We only enable this feature when booted in HYP mode and that
      the device-tree reported a suitable CPU interface. Observable behaviour
      should remain unchanged.

      While this works perfectly for Linux (we only have a single priority),

      - A write to ICC_DIR_EL1 marks the interrupt as inactive, meaning
        it can now be taken again.

      This patch converts the driver to be able to use this new mode,
      depending on whether or not the kernel can behave as a hypervisor.
      No feature change.

      We rename fam15h_power_is_internal_node0() function to
      should_load_on_this_node(), because it may not be node0 from KV and
      on, and they are single-node processors.

      mmc: sunxi: fix timeout in sunxi_mmc_oclk_onoff

      The 250ms timeout is too short.

      On my system enabling the oclk takes under 50ms and disabling slightly
      over 100ms when idle. Under load disabling the clock can take over
      350ms.

      This does not make mmc clock gating look like good option to have on
      sunxi but the system should not crash with mmc clock gating enabled
      nonetheless.

      mmc: sdhci-esdhc-imx: change default watermark level and burst length

      By default, for all imx SoC types, the watermark level is 16, and the
      burst length is 8. But if the SDIO/SD/MMC I/O speed is fast enough,
      this default watermark level and burst length will be the performance
      bottleneck.

      For example, i.MX7D support eMMC HS400 mode, this mode can run in 8 bit,
      200MHZ DDR mode. So the I/O speed improve a lot compare to SD3.0.
      The default burst length is 8, if we don't change this value, in
      HS400 mode, when we do eMMC read operation, we can find that the
      clock signal will stop for a period of time. This means the speed
      of data moving on AHB bus is slower than I/O speed. So we should
      improve the speed of data moving on AHB bus.

      This patch set the default burst length as 16, and set the default
      watermark level as 64. The test result is the clock signal has
      no stop during the eMMC HS400 operation.

      Currently we find that if a usdhc is choosed to boot system, then ROM

      This will make performance drop a lot if this usdhc's burst length is

      Also note that powernv LEDS driver needs NEW_LEDS and LEDS_CLASS

      powerpc/iommu: Set default DMA offset in dma_dev_setup

      Commit e91c25111aa3 "powerpc/iommu: Cleanup setting of DMA base/offset"
      expects that the default DMA offset is set from pnv_ioda_setup_bus_dma()
      which is correct unless it is SRIOV where the code flow is different -
      at the moment when pnv_ioda_setup_bus_dma() is called, PCI devices for
      VFs are not created yet.

      This adds missing set_dma_offset() to pnv_pci_ioda_dma_dev_setup() to
      cover the case of SRIOV.

      Note that we still need set_dma_offset() in pnv_ioda_setup_bus_dma() as
      at the boot time pnv_pci_ioda_dma_dev_setup() is called when no PE was
      created yet, this happens at the PHB fixup stage.

      ARCv2: perf: Support sampling events using overflow interrupts

      In times of ARC 700 performance counters didn't have support of
      interrupt an so for ARC we only had support of non-sampling events.

      Put simply only "perf stat" was functional.

      Now with ARC HS we have support of interrupts in performance counters
      which this change introduces support of.

      ARC performance counters act in the following way in regard of
      interrupts generation.
       [1] A counter counts starting from value set in PCT_COUNT register pair
       [2] Once counter reaches value set in PCT_INT_CNT interrupt is raised

      Basic setup look like this:
       [1] PCT_COUNT = 0;
       [2] PCT_INT_CNT = __limit_value__;
       [3] Enable interrupts for that counter and let it run
       [4] Let counter reach its limit
       [5] Handle interrupt when it happens

      Note that PCT HW block is build in CPU core and so ints interrupt
      line (which is basically OR of all counters IRQs) is wired directly to
      top-level IRQC. That means do de-assert PCT interrupt it's required to
      reset IRQs from all counters that have reached their limit values.

      ARCv2: perf: implement "event_set_period"

      This generalization prepares for support of overflow interrupts.

      Hardware event counters on ARC work that way:
      Each counter counts from programmed start value (set in
      ARC_REG_PCT_COUNT) to a limit value (set in ARC_REG_PCT_INT_CNT) and
      once limit value is reached this timer generates an interrupt.

      Even though this hardware implementation allows for more flexibility,
      in Linux kernel we decided to mimic behavior of other architectures
      this way:

       [1] Set limit value as half of counter's max value (to allow counter to
           run after reaching it limit, see below for more explanation):
       ---------->8-----------
       arc_pmu->max_period = (1ULL << counter_size) / 2 - 1ULL;
       ---------->8-----------

       [2] Set start value as "arc_pmu->max_period - sample_period" and then
      count up to the limit

      Our event counters don't stop on reaching max value (the one we set in
      ARC_REG_PCT_INT_CNT) but continue to count until kernel explicitly
      stops each of them.

      And setting a limit as half of counter capacity is done to allow
      capturing of additional events in between moment when interrupt was
      triggered until we're actually processing PMU interrupts. That way
      we're trying to be more precise.

      For example if we count CPU cycles we keep track of cycles while
      running through generic IRQ handling code:

       [1] We set counter period as say 100_000 events of type "crun"
       [2] Counter reaches that limit and raises its interrupt
       [3] Once we get in PMU IRQ handler we read current counter value from
      ARC_REG_PCT_SNAP ans see there something like 105_000.

      If counters stop on reaching a limit value then we would miss
      additional 5000 cycles.

      arm64: flush FP/SIMD state correctly after execve()

      When a task calls execve(), its FP/SIMD state is flushed so that
      none of the original program state is observeable by the incoming
      program.

      However, since this flushing consists of setting the in-memory copy
      of the FP/SIMD state to all zeroes, the CPU field is set to CPU 0 as
      well, which indicates to the lazy FP/SIMD preserve/restore code that
      the FP/SIMD state does not need to be reread from memory if the task
      is scheduled again on CPU 0 without any other tasks having entered
      userland (or used the FP/SIMD in kernel mode) on the same CPU in the
      mean time. If this happens, the FP/SIMD state of the old program will
      still be present in the registers when the new program starts.

      So set the CPU field to the invalid value of NR_CPUS when performing
      the flush, by calling fpsimd_flush_task_state().

      This is a more natural format that lets us format it with the appropriate
      printk specifier as needed.

      This also lets us handle v4-mapped ipv6 addresses a little more nicely, by
      storing the addr as an actual v4 sockaddr in conn->local_sockaddr.

      Finally, we no longer need to maintain variables for port, since this is
      contained in sockaddr. Remove iscsi_np.np_port and iscsi_conn.local_port.

      target/iscsi: Fix np_ip bracket issue by removing np_ip

      Revert commit 1997e6259, which causes double brackets on ipv6
      inaddr_any addresses.

      Since we have np_sockaddr, if we need a textual representation we can
      use "%pISc".

      Change iscsit_add_network_portal() and iscsit_add_np() signatures to 
remove
      *ip_str parameter.

      Fix and extend some comments earlier in the function.

      Tested to work for :: and ::1 via iscsiadm, previously :: failed, see

      cxl: Remove racy attempt to force EEH invocation in reset

      cxl_reset currently PERSTs the slot, and then repeatedly tries to
      read MMIO space in order to kick off EEH.

      There are 2 problems with this: it's unnecessary, and it's racy.

      It's unnecessary because the PERST will bring down the PHB link.
      That will be picked up by the CAPP, which will send out an HMI.
      Skiboot, noticing an HMI from the CAPP, will send an OPAL
      notification to the kernel, which will trigger EEH recovery.

      It's also racy: the EEH recovery triggered by the CAPP will
      eventually cause the MMIO space to have its mapping invalidated
      and the pointer NULLed out. This races with our attempt to read
      the MMIO space. This is causing OOPSes in testing.

      Simply drop all the attempts to force EEH detection, and trust
      that Skiboot will send the notification and that we'll act on it.
      The Skiboot code to send the EEH notification has been in Skiboot
      for as long as CAPP recovery has been supported, so we don't need
      to worry about breaking obscure setups with ancient firmware.

      Merge branch 'drm-dwhdmi-devel' of 
git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next

      Here are some development updates for the Synopsis Designware HDMI driver,
      which clean up some of the code, and start preparing to add audio support
      to the driver.  This series of patches are based on a couple of dependent
      commits from the ALSA tree.

      Briefly, the updates are:
      - move comments which should have moved with the phy values to the IMX
        part of the driver.
      - clean up the phy configuration: to all lookups before starting to
        program the phy.
      - clean up the HDMI clock regenerator code
      - use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
        the code to be subsequently simplified
      - remove the unused 'regmap' pointer in struct dw_hdmi
      - use the bridge drm device rather than the connector (we're the bridge
        code)
      - remove private hsync/vsync/interlaced flags, getting them from the
        DRM mode structure instead.
      - implement interface functions to support audio - setting the audio
        sample rate, and enabling the audio clocks.
      - removal of broken pixel repetition support
      - cleanup DVI vs HDMI sink handling
      - enable audio only if connected device supports audio
      - avoid double-enabling bridge in the sink path (once in mode_set, and
        again in commit)
      - rename mis-named dw_hdmi_phy_enable_power()
      - fix bridge enable/disable handing, so a plug-in event doesn't
        reconfigure the bridge if DRM has disabled the output
      - fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name

      These are primerily preparitory patches for the AHB audio driver and
      the I2S audio driver (from Rockchip) for this IP.

      cxlflash: Base error recovery support

      Introduce support for enhanced I/O error handling.

      A device state is added to track 3 possible states of the device:

      Normal - the device is operating normally and is fully operational

      Limbo - the device is in a reset/recovery scenario and its operational
              status is paused

      Failed/terminating - the device has either failed to be reset/recovered
                           or is being terminated (removed); it is no longer
                           operational

      All operations are allowed when the device is operating normally. When the
      device transitions to limbo state, I/O must be paused. To help accomplish
      this, a wait queue is introduced where existing and new threads can wait
      until the device is no longer in limbo. When coming out of limbo, threads
      need to check the state and error out gracefully when encountering the
      failed state. When the device transitions to the failed/terminating state,
      normal operations are no longer allowed. Only specially designated
      operations related to graceful cleanup are permitted.

      but if login_retry has been set already, that would fail to set the

      scsi_error: should not get sense for timeout IO in scsi error handler

      scsi_error: should not get sense for timeout IO in scsi error handler

      When an IO timeout occurs, the IO will be aborted in
      scsi_abort_command() and SCSI_EH_ABORT_SCHEDULED will be set. Because
      of that, the SCSI_EH_CANCEL_CMD will be clear in scsi_eh_scmd_add().
      So when scsi error handler starts, it will get sense for this
      timeout IO and the scmd of the IO request will be reused. In that
      case, the scmd may be double released when racing with io_done(),
      which will result in crash.
      SO SCSI_EH_ABORT_SCHEDULED should also be checked when getting sense.
      The bug maybe reproduced when the link between host and disk is
      unstable.

      hpsa: fix issues with multilun devices

      A regression was introduced into the hpsa driver a while back so
      non-zero LUNs of multi-LUN devices may no longer be presented via
      a SAS based Smart Array. I have not done a bisection to discover
      the change that caused it.

      The CISS firmware specification (available on sourceforge)
      defines an 8 byte lunid that describes devices that the Smart
      Array can see/present to the system. The current code in the hpsa
      driver attempts to find matches for non-zero LUNs with LUN 0 for
      a bus/target by zeroing out byte 4 of the lunid and find a match.

      This method is sufficient for SCSI based Smart Arrays because
      byte 5 is always 0. For SAS based Smart arrays byte 5 of the
      lunid contains the path number for a multipath device and
      either one or two bits (the documentation does not define how
      many bits are used but it appears it may be one only) that
      indicate if the given path number in byte 5 must always be
      used to access that device. Byte 5 may not always be zero.

      The following are lunids (spaces added for clarity) for a
      MSL2024 single drive library connected via a H241 Smart Array:

      00 00 00 00 01 00 00 01 (changer)
      00 00 00 00 00 80 00 01 (tape)

      In the 4th byte (counting from 0) you can see that the tape
      is LUN 0 and the changer is LUN 1. The 0x80 set in the 5th byte
      for the tape drive means the driver should force access to
      path 0 (the library in this case was connected to one path only
      anyway).

      After the changes we can see the following in the dmesg output:

      scsi 0:3:0:0: RAID              HP       H241             1.18 \
      PQ: 0 ANSI: 5
      scsi 0:2:0:0: Sequential-Access HP       Ultrium 6-SCSI   354W \
      PQ: 0 ANSI: 6
      scsi 0:2:0:1: Medium Changer    HP       MSL G3 Series    8.70 \
      PQ: 0 ANSI: 5

      Showing that the changer is correctly identified as LUN 1 of
      bus 2 target 0. Before the change the changer device is not seen.

      ACPI, PCI: Penalize legacy IRQ used by ACPI SCI

      Nick Meier reported a regression with HyperV that "
        After rebooting the VM, the following messages are logged in syslog
        when trying to load the tulip driver:
          tulip: Linux Tulip drivers version 1.1.15 (Feb 27, 2007)
          tulip: 0000:00:0a.0: PCI INT A: failed to register GSI
          tulip: Cannot enable tulip board #0, aborting
          tulip: probe of 0000:00:0a.0 failed with error -16
        Errors occur in 3.19.0 kernel
        Works in 3.17 kernel.
      "

      According to the ACPI dump file posted by Nick at
      https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1440072

      The ACPI MADT table includes an interrupt source overridden entry for
      ACPI SCI:
      [236h 0566  1]                Subtable Type : 02 <Interrupt Source 
Override>
      [237h 0567  1]                       Length : 0A
      [238h 0568  1]                          Bus : 00
      [239h 0569  1]                       Source : 09
      [23Ah 0570  4]                    Interrupt : 00000009
      [23Eh 0574  2]        Flags (decoded below) : 000D
                                         Polarity : 1
                                     Trigger Mode : 3

      And in DSDT table, we have _PRT method to define PCI interrupts, which
      eventually goes to:
              Name (PRSA, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSB, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSC, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSD, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })

      According to the MADT and DSDT tables, IRQ 9 may be used for:
       1) ACPI SCI in level, high mode
       2) PCI legacy IRQ in level, low mode
      So there's a conflict in polarity setting for IRQ 9.

      Prior to commit cd68f6bd53cf ("x86, irq, acpi: Get rid of special
      handling of GSI for ACPI SCI"), ACPI SCI is handled specially and
      there's no check for conflicts between ACPI SCI and PCI legagy IRQ.
      And it seems that the HyperV hypervisor doesn't make use of the
      polarity configuration in IOAPIC entry, so it just works.

      Commit cd68f6bd53cf gets rid of the specially handling of ACPI SCI,
      and then the pin attribute checking code discloses the conflicts
      between ACPI SCI and PCI legacy IRQ on HyperV virtual machine,
      and rejects the request to assign IRQ9 to PCI devices.

      So penalize legacy IRQ used by ACPI SCI and mark it unusable if ACPI
      SCI attributes conflict with PCI IRQ attributes.

      i40e: Remove redundant and unneeded messages

      The kernel notifies all VXLAN capable registered drivers, i.e. any
      driver that implements ndo_add_vxlan_port(), of the addition of a
      port so that the driver can track which ports are in use.  There's
      no need to log this - it just fills the system log with useless and
      irksome noise.

      Also, when failing to init SR-IOV interfaces the driver was printing the
      same message twice. Just remove the inner printk and let the outer message
      catch enable as well as the other failures.

      i40e: Fix legacy interrupt mode in the driver

      This patch fixes the driver flow to take into account legacy interrupts.
      Over time we added code that assumes MSIX is the only mode that the
      driver runs in. It also enables a legacy workaround to trigger SWINT
      when the TX ring has non-cache aligned descriptors pending and interrupts
      are disabled.

      We work with a single vector in MSI mode too, so apply the same
      restrictions as Legacy.

      drm/amdgpu: adjust the judgement of removing fence callback

      The fence in the array may be skipped if wait_all is false,
      thus the related callback is not initialized with list head.
      So removing this kind callback will cause NULL pointer reference.

      There are trackpoint devices that fail to respond to the PS2 command

      ARM: software-based priviledged-no-access support

      Provide a software-based implementation of the priviledged no access
      support found in ARMv8.1.

      Userspace pages are mapped using a different domain number from the
      kernel and IO mappings.  If we switch the user domain to "no access"
      when we enter the kernel, we can prevent the kernel from touching
      userspace.

      However, the kernel needs to be able to access userspace via the
      various user accessor functions.  With the wrapping in the previous
      patch, we can temporarily enable access when the kernel needs user
      access, and re-disable it afterwards.

      This allows us to trap non-intended accesses to userspace, eg, caused
      by an inadvertent dereference of the LIST_POISON* values, which, with
      appropriate user mappings setup, can be made to succeed.  This in turn
      can allow use-after-free bugs to be further exploited than would
      otherwise be possible.

      ARM: entry: provide uaccess assembly macro hooks

      Provide hooks into the kernel entry and exit paths to permit control
      of userspace visibility to the kernel.  The intended use is:

      - on entry to kernel from user, uaccess_disable will be called to
        disable userspace visibility
      - on exit from kernel to user, uaccess_enable will be called to
        enable userspace visibility
      - on entry from a kernel exception, uaccess_save_and_disable will be
        called to save the current userspace visibility setting, and disable
        access
      - on exit from a kernel exception, uaccess_restore will be called to
        restore the userspace visibility as it was before the exception
        occurred.

      These hooks allows us to keep userspace visibility disabled for the
      vast majority of the kernel, except for localised regions where we
      want to explicitly access userspace.

       #endif

      such as one defintion being updated, but the other definitions miss out.
      Where the contents of a macro needs to be conditional, the hint is in
      the first clause of this very sentence.  "contents" "conditional".  Not
      multiple separate definitions, especially not when much of the macro
      is the same between different configs.

      miss-out on the uaccess updates.

      f2fs: update extent tree in batches

      This patch introduce a new helper f2fs_update_extent_tree_range which can
      do extent mapping update at a specified range.

      The main idea is:
      1) punch all mapping info in extent node(s) which are at a specified 
range;
      2) try to merge new extent mapping with adjacent node, or failing that,
         insert the mapping into extent tree as a new node.

      In order to see the benefit, I add a function for stating time stamping
      count as below:

      uint64_t rdtsc(void)
      {
        uint32_t lo, hi;
        __asm__ __volatile__ ("rdtsc" : "=a" (lo), "=d" (hi));
        return (uint64_t)hi << 32 | lo;
      }

      My test environment is: ubuntu, intel i7-3770, 16G memory, 256g micron 
ssd.

      truncation path:  update extent cache from truncate_data_blocks_range
      non-truncataion path:     update extent cache from other paths
      total:                    all update paths

      a) Removing 128MB file which has one extent node mapping whole range of
      file:
      1. dd if=/dev/zero of=/mnt/f2fs/128M bs=1M count=128
      2. sync
      3. rm /mnt/f2fs/128M

      Before:
                total           count           average
      truncation:       7651022         32768           233.49

      Patched:
                total           count           average
      truncation:       3321            33              100.64

      b) fsstress:
      fsstress -d /mnt/f2fs -l 5 -n 100 -p 20
      Test times:               5 times.

      truncation:       5812480.6       20911.6         277.95
      non-truncation:   7783845.6       13440.8         579.12
      total:            13596326.2      34352.4         395.79

      total:            8637127.4       16704.4         517.06

      1) For the updates in truncation path:
       - we can see updating in batches leads total tsc and update count 
reducing
         explicitly;
       - besides, for a single batched updating, punching multiple extent nodes
         in a loop, result in executing more operations, so our average tsc
         increase intensively.
      2) For the updates in non-truncation path:
       - there is a little improvement, that is because for the scenario that we
         just need to update in the head or tail of extent node, new interface
         optimize to update info in extent node directly, rather than removing
         original extent node for updating and then inserting that updated one
         into cache as new node.

      clk: pistachio: Fix PLL rate calculation in integer mode

      .recalc_rate callback for the fractional PLL doesn't take operating
      mode into account when calculating PLL rate. This results in
      the incorrect PLL rates when PLL is operating in integer mode.

      Operating mode of fractional PLL is based on the value of the
      fractional divider. Currently it assumes that the PLL will always
      be configured in fractional mode which may not be
      the case. This may result in the wrong output frequency.

      Also vco was calculated based on the current operating mode which
      makes no sense because .set_rate is setting operating mode. Instead,
      vco should be calculated using PLL settings that are about to be set.

      clk: pistachio: Fix override of clk-pll settings from boot loader

      PLL enable callbacks are overriding PLL mode (int/frac) and
      Noise reduction (on/off) settings set by the boot loader which
      results in the incorrect clock rate.

      PLL mode and noise reduction are defined by the DSMPD and DACPD bits
      of the PLL control register. PLL .enable() callbacks enable PLL
      by deasserting all power-down bits of the PLL control register,
      including DSMPD and DACPD bits, which is not necessary since
      these bits don't actually enable/disable PLL.

      This commit fixes the problem by removing DSMPD and DACPD bits
      from the "PLL enable" mask.

      act_bpf: remove spinlock in fast path

      v1 version had a race condition in cleanup path of bpf_prog.
      I tried to fix it by adding new callback 'cleanup_rcu' to 'struct 
tcf_common'
      and call it out of act_api cleanup path, but Daniel noticed
      (thanks for the idea!) that most of the classifiers already do action 
cleanup
      out of rcu callback.
      So instead this set of patches converts tcindex and rsvp classifiers to 
call
      tcf_exts_destroy() after rcu grace period and since action cleanup logic
      in __tcf_hash_release() is only called when bind and refcnt goes to zero,
      it's guaranteed that cleanup() callback is called from rcu callback.
      More specifically:
      patches 1 and 2 - simple fixes
      patches 2 and 3 - convert tcf_exts_destroy in tcindex and rsvp to call_rcu
      patch 5 - removes spin_lock from act_bpf

      The cleanup of actions is now universally done after rcu grace period
      and in the future we can drop (now unnecessary) call_rcu from 
tcf_hash_destroy()
      patch 5 is using synchronize_rcu() in act_bpf replacement path, since it's
      very rare and alternative of dynamically allocating 'struct tcf_bpf_cfg' 
just
      to pass it to call_rcu looks even less appealing.

      Similar to act_gact/act_mirred, act_bpf can be lockless in packet

      Replacement of existing act_bpf (very rare) is done with synchronize_rcu()
      and final destruction is done from tc_action_ops->cleanup() callback that 
is
      called from 
tcf_exts_destroy()->tcf_action_destroy()->__tcf_hash_release() when
      bind and refcnt reach zero which is only possible when classifier is 
destroyed.
      Previous two patches fixed the last two classifiers (tcindex and rsvp) to
      call tcf_exts_destroy() from rcu callback.

      Similar to gact/mirred there is a race between prog->filter and
      prog->tcf_action. Meaning that the program being replaced may use
      previous default action if it happened to return TC_ACT_UNSPEC.
      act_mirred race betwen tcf_action and tcfm_dev is similar.
      In all cases the race is harmless.
      Long term we may want to improve the situation by replacing the whole
      tc_action->priv as single pointer instead of updating inner fields one by 
one.

      Input: synaptics - fix handling of disabling gesture mode

      Bit 2 of the mode byte has dual meaning: it can disable reporting of
      gestures when touchpad works in Relative mode or normal Absolute mode,
      or it can enable so called Extended W-Mode when touchpad uses enhanced
      Absolute mode (W-mode). The extended W-Mode confuses our driver and
      causes missing button presses on some Thinkpads (x250, T450s), so let's
      make sure we do not enable it.

      Also, according to the spec W mode "... bit is defined only in Absolute
      mode on pads whose capExtended capability bit is set. In Relative mode and
      in TouchPads without this capability, the bit is reserved and should be
      left at 0.", so let's make sure we respect this requirement as well.

      i2c: allow specifying separate wakeup interrupt in device tree

      Instead of having each i2c driver individually parse device tree data in
      case it or platform supports separate wakeup interrupt, and handle
      enabling and disabling wakeup interrupts in their power management
      routines, let's have i2c core do that for us.

      Platforms wishing to specify separate wakeup interrupt for the device
      should use named interrupt syntax in their DTSes:

        interrupt-parent = <&intc1>;
        interrupts = <5 0>, <6 0>;
        interrupt-names = "irq", "wakeup";

      This patch is inspired by work done by Vignesh R <vigneshr@xxxxxx> for
      pixcir_i2c_ts driver.

      Note that the original code tried to preserve any existing wakeup
      settings from userspace but was not quite right in that regard:
      it would preserve wakeup flag set by userspace upon driver rebinding;
      but it would re-arm the wakeup flag if it was disabled by userspace.

      We think that resetting the flag upon re-binding the driver is proper
      behavior as the driver is responsible for setting up and handling
      wakeups.

      s390/sclp_vt220: support magic sysrequests

      Implement magic sysrequest handling for the VT220 terminal (also known as
      the Integrated ASCII console on the HMC/SE).
      To invoke a "magic sysrequest" function, press "Ctrl+o" followed by a
      second character that designates the debugging function.

      The handling of the sysrq is scheduled away from the SCLP IRQ context;
      because large amounts of sysrq output might fill up the console buffers.
      The console might deadlock because it cannot empty the buffers while still
      in the receiving IRQ context.  This behavior is the same as for the SCLP
      console.

      perf probe: Support probing at absolute address

      It should be useful to allow 'perf probe' probe at absolute offset of a
      target. For example, when (u)probing at a instruction of a shared object
      in a embedded system where debuginfo is not avaliable but we know the
      offset of that instruction by manually digging.

      This patch enables following perf probe command syntax:

        # perf probe 0xffffffff811e6615

      And

        # perf probe /lib/x86_64-linux-gnu/libc-2.19.so 0xeb860

      In the above example, we don't need a anchor symbol, so it is possible
      to compute absolute addresses using other methods and then use 'perf
      probe' to create the probing points.

      v1 -> v2:
        Drop the leading '+' in cmdline;
        Allow uprobing at offset 0x0;
        Improve 'perf probe -l' result when uprobe at area without debuginfo.

      v2 -> v3:
        Split bugfix to a separated patch.

      Test result:

        # perf probe 0xffffffff8119d175 %ax
        # perf probe sys_write %ax
        # perf probe /lib64/libc-2.18.so 0x0 %ax

      perf probe: Fix error reported when offset without function

      This patch fixes a bug that, when offset is provided but function is
      lost, parse_perf_probe_point() will give a "" string as function name,
      so the checking code at the end of parse_perf_probe_point() become
      useless.  For example:

        # perf probe +0x1234
        Failed to find symbol  in kernel
          Error: Failed to add events.

      After this patch:

        # perf probe +0x1234
        Semantic error :Offset requires an entry function.
          Error: Command Parse Error.

      perf probe: Fix list result when address is zero

      When manually added uprobe point with zero address, 'perf probe -l'
      reports error. For example:

        # echo p:probe_libc/abs_0 /path/to/lib.bin:0x0 arg1=%ax > \
                 /sys/kernel/debug/tracing/uprobe_events

        # perf probe -l
        Error: Failed to show event list.

      Probing at 0x0 is possible and useful when lib.bin is not a normal
      shared object but is manually mapped. However, in this case kernel
      report:

        # cat /sys/kernel/debug/tracing/uprobe_events
        p:probe_libc/abs_0 /path/to/lib.bin:0x          (null) arg1=%ax

      This patch supports the above kernel output.

      ALSA: usb-audio: Avoid nested autoresume calls

      After the recent fix of runtime PM for USB-audio driver, we got a
      lockdep warning like:

        =============================================
        [ INFO: possible recursive locking detected ]
        4.2.0-rc8+ #61 Not tainted
        ---------------------------------------------
        pulseaudio/980 is trying to acquire lock:
         (&chip->shutdown_rwsem){.+.+.+}, at: [<ffffffffa0355dac>] 
snd_usb_autoresume+0x1d/0x52 [snd_usb_audio]
        but task is already holding lock:
         (&chip->shutdown_rwsem){.+.+.+}, at: [<ffffffffa0355dac>] 
snd_usb_autoresume+0x1d/0x52 [snd_usb_audio]

      This comes from snd_usb_autoresume() invoking down_read() and it's
      used in a nested way.  Although it's basically safe, per se (as these
      are read locks), it's better to reduce such spurious warnings.

      The read lock is needed to guarantee the execution of "shutdown"
      (cleanup at disconnection) task after all concurrent tasks are
      finished.  This can be implemented in another better way.

      Also, the current check of chip->in_pm isn't good enough for
      protecting the racy execution of multiple auto-resumes.

      This patch rewrites the logic of snd_usb_autoresume() & co; namely,
      - The recursive call of autopm is avoided by the new refcount,
        chip->active.  The chip->in_pm flag is removed accordingly.
      - Instead of rwsem, another refcount, chip->usage_count, is introduced
        for tracking the period to delay the shutdown procedure.  At
        the last clear of this refcount, wake_up() to the shutdown waiter is
        called.
      - The shutdown flag is replaced with shutdown atomic count; this is
        for reducing the lock.
      - Two new helpers are introduced to simplify the management of these
        refcounts; snd_usb_lock_shutdown() increases the usage_count, checks
        the shutdown state, and does autoresume.  snd_usb_unlock_shutdown()
        does the opposite.  Most of mixer and other codes just need this,
        and simply returns an error if it receives an error from lock.

      perf probe: Fix list result when symbol can't be found

      'perf probe -l' reports error if it is unable find symbol through
      address. Here is an example.

        # echo 'p:probe_libc/abs_5 /lib64/libc.so.6:0x5' >
                /sys/kernel/debug/tracing/uprobe_events
        # cat /sys/kernel/debug/tracing/uprobe_events
         p:probe_libc/abs_5 /lib64/libc.so.6:0x0000000000000005
        # perf probe -l
          Error: Failed to show event list

      Also, this situation triggers a logical inconsistency in
      convert_to_perf_probe_point() that, it returns ENOMEM but actually it
      never try strdup().

      This patch removes !tp->module && !is_kprobe condition, so it always
      uses address to build function name if symbol not found.

      Test result:

        # perf probe -l
          probe_libc:abs_5     (on 0x5 in /lib64/libc.so.6)

      perf probe: Prevent segfault when reading probe point with absolute

      'perf probe -l' panic if there is a manually inserted probing point with

      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
      decl")).

      That's not a problem for vpe_run() because Kconfig ensures there's never
      more than one definition:

        - vpe_run() is defined in arch/mips/kernel/vpe-mt.c if
          CONFIG_MIPS_VPE_LOADER_MT=y

        - vpe_run() is defined in arch/mips/mti-malta/malta-amon.c if
          CONFIG_MIPS_CMP=y

        - CONFIG_MIPS_VPE_LOADER_MT cannot be set if CONFIG_MIPS_CMP=y

      But it's simpler to verify correctness if we remove "weak" from the 
picture
      and test the config symbols directly.

      Remove "weak" from the vpe_run() declaration and use #if to test whether a
      definition should be present.

      MIPS: VPE: Exit vpe_release() early if vpe_run() isn't defined

      vpe_run() is a weak symbol.  If there's no definition of it, its value is
      zero.

      If vpe_run is zero, return failure early.  We're going to fail anyway, so
      there's no point in getting a VPE and attempting to load it.

      MIPS: Remove "weak" from platform_maar_init() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
      decl")).

      platform_maar_init() is defined in:

        - arch/mips/mm/init.c (where it is marked "weak")
        - arch/mips/mti-malta/malta-memory.c (without annotation)

      The "weak" attribute on the platform_maar_init() extern declaration 
applies
      to the platform-specific definition in arch/mips/mti-malta/malta-memory.c,
      so both definitions are weak, and which one we get depends on link order.

      Remove the "weak" attribute from the declaration.  That makes the malta
      definition strong, so it will always be preferred if it is present.

      There's only one implementation of mips_cpc_phys_base(), and it's only 
used

      MIPS: ops-emma2rh: Drop nonsensical db_assert

      The db_assert call checks whether the bus_num pointer is non-NULL, but
      does so after said pointer has been dereferenced by the assignment on
      the previous line. Thus the check is pointless & likely to have been
      optimised out by the compiler anyway. The check_args function is static
      & only ever called from the local file with bus_num being a pointer to
      an on-stack variable, so the check seems somewhat overzealous anyway.
      Simply remove it.

      MIPS: octeon: Replace the homebrewn flow handler

      The gpio interrupt handling of octeon contains a homebrewn flow
      handler which calls either handle_level_irq or handle_edge_irq
      depending on the trigger type. Thats an extra conditional and call in
      the interrupt handling path. The proper way to handle different types
      and therefor different flows is to update the handler in the
      irq_set_type() callback.

      Remove the extra indirection and add the handler update to
      octeon_irq_ciu_gpio_set_type(). At mapping time it defaults to
      handle_level_irq which gets updated if the device tree contains a
      different trigger type.

      The various interrupt flow handlers in ath79 are cascading interrupt

      is zero because its a complete noop:

      disable_irq_nosync() merily increments the disable count without
      actually masking the interrupt. enable_irq() soleley decrements the
      disable count without touching the interrupt chip. The interrupt
      cannot arrive again because the complete call chain runs with
      interrupts disabled.

      IRQCHIP: irq-mips-gic: Extend GIC accessors for 64-bit CMs

      Previously, the GIC accessors were only accessing u32 registers but
      newer CMs may actually be 64-bit on MIPS64 cores. As a result of which,
      extended these accessors to support 64-bit reads and writes.

      MIPS: CM: Add support for reporting CM cache errors

      The CM cache error reporting code is not Malta specific and as such it
      should live in the mips-cm.c file. Moreover, CM2 and CM3 differ in the
      way cache errors are being recorded to the registers so extend the
      previous code to add support for the CM3 as well.

      MIPS: mips-cm: Extend CM accessors for 64-bit CPUs

      Previously, the CM accessors were only accessing CM registers as u32
      types instead of using the native CM register with. However, newer CMs
      may actually be 64-bit on MIPS64 cores. Fortunately, current 64-bit CMs
      (CM3) hold all the useful configuration bits in the lower half of the
      64-bit registers (at least most of them) so they can still be accessed
      using the current 32-bit accessors.

      pinctrl: mediatek: Fix multiple registration issue.

      Since our common driver need support main chip and PMU
      at the same time, that means it will register two
      pinctrl device, and the pinctrl_desc structure should
      be used two times.

      But pinctrl_desc use global static definition, then
      the latest registered pinctrl device will overwrite
      the old one's, all members in pinctrl_desc will set to
      the new one's, such as name, pins and pins numbers, etc.
      This is a bug.

      Move pinctrl_desc into mtk_pinctrl, assign new value for
      each pinctrl device to fix it.

      powerpc/PCI: Disable MSI/MSI-X interrupts at PCI probe time in OF case

      Since commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if
      kernel doesn't support MSI"), the setup of dev->msi_cap/msix_cap and the
      disable of MSI/MSI-X interrupts isn't being done at PCI probe time, as
      the logic responsible for this was moved in the aforementioned commit
      from pci_device_add() to pci_setup_device(). The latter function is not
      reachable on PowerPC pseries platform during Open Firmware PCI probing
      time.

      This exhibits as drivers not being able to enable MSI, eg:

        bnx2x 0000:01:00.0: no msix capability found

      This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X
      during PCI probe time on pSeries platform.

      PCI: Make pci_msi_setup_pci_dev() non-static for use by arch code

      Commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel
      doesn't support MSI") changed the location of the code that initialises
      dev->msi_cap/msix_cap and then disables MSI/MSI-X interrupts at PCI
      probe time in devices that have this flag set. It moved the code from
      pci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(),
      called by pci_setup_device().

      The pseries PCI probing code does not call pci_setup_device(), so since
      the aforementioned commit the function pci_msi_setup_pci_dev() is not
      called and MSI/MSI-X interrupts are left enabled. Additionally because
      dev->msi_cap/msix_cap are not initialised no driver can ever enable
      MSI/MSI-X.

      To fix this, the pseries PCI probe should manually call
      pci_msi_setup_pci_dev(), so this patch makes it non-static.

      Fixes: 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel 
doesn't support MSI")

      ath10k: fix compilation warnings in wmi phyerr pull function

      Below compilation warnings are observed in gcc version 4.8.2.
      Even though it's not seen in bit older gcc versions (for ex, 4.7.3),
      It's good to fix it by changing format specifier from %d to
      %zd in wmi pull phyerr functions.

      ath10k: add qca6164 support

      This adds additional 0x0041 PCI Device ID
      definition to ath10k for QCA6164 which is a 1
      spatial stream sibling of the QCA6174 (which is 2
      spatial stream chip).

      The QCA6164 needs a dedicated board.bin file which
      is different than the one used for QCA6174. If the
      board.bin is wrong the device will crash early
      while trying to boot firmware. The register dump
      will look like this:

       ath10k_pci 0000:02:00.0: firmware register dump:
       ath10k_pci 0000:02:00.0: [00]: 0x05010000 0x000015B3 0x000A012D 
0x00955B31
       ...

      Note the value 0x000A012D.

      ath10k: add spectral scan support for 10.4 fw

      To enable/configure spectral scan parameters in 10.4 firmware, existing
      wmi spectral related functions can be reused. Link those functions in
      10.4 wmi ops table.

      In addition, adjust bin size (only when size is 68 bytes) before reporting
      bin samples to user space. The background for this adjustment is that
      qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
      mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
      carries band edge detection data (+32) mainly used in radar detection
      purpose. Additional last 4 bytes are stripped to make bin size valid one.

      This bin size adjustment will happen only for qca99x0, all other chipsets
      will report proper bin sizes (64/128) without extra 4 bytes being added
      at the end. The changes are validated in qca99x0 using 10.4 firmware.

      gpio: omap: fix clk_prepare/unprepare usage

      As per CCF documentation (clk.txt) the clk_prepare/unprepare APIs
      are not allowed in atomic context. But now OMAP GPIO driver
      uses them while applying debounce settings and as part
      of PM runtime irqsafe operations:

      - omap_gpio_debounce() is holding the lock with IRQs off.
        + omap2_set_gpio_debounce()
         + clk_prepare_enable()
          + clk_prepare() this one might sleep.

      - pm_runtime_get_sync() is holding the lock with IRQs off
        + omap_gpio_runtime_suspend()
          + raw_spin_lock_irqsave()
          + omap_gpio_dbck_disable()
            + clk_disable_unprepare()

      Hence, fix it by moeving dbclk prepare/unprepare in OMAP GPIO
      omap_gpio_probe/omap_gpio_remove. Also, while here, ensure that
      debounce functionality is disabled if clk_get() failed,
      because otherwise kernel will carsh in omap2_set_gpio_debounce().

      gpio: omap: fix omap2_set_gpio_debounce

      According to TRMs:

      Required input line stable =
        (the value of the GPIO_DEBOUNCINGTIME[7:0].DEBOUNCETIME + 1) Ã?â?? 31,
      where the value of the GPIO_DEBOUNCINGTIME[7:0].DEBOUNCETIME bit field
      is from 0 to 255.

      But now omap2_set_gpio_debounce() will calculate debounce time and
      behave incorrectly in the following cases:
      1) requested debounce time is !0 and <32
         calculated DEBOUNCETIME = 0x1 == 62 us;
         expected value of DEBOUNCETIME = 0x0 == 31us
      2) requested debounce time is 0
         calculated DEBOUNCETIME = 0x1 == 62 us;
         expected: disable debounce and DEBOUNCETIME = 0x0
      3) requested debounce time is >32 and <63
         calculated DEBOUNCETIME = 0x0 and debounce will be disabled;
         expected: enable debounce and DEBOUNCETIME = 0x1 == 62 us

      Hence, rework omap2_set_gpio_debounce() to fix above cases:
      1) introduce local variable "enable" and use it to identify
      when debounce need to be enabled or disabled. Disable debounce
      if requested debounce time is 0.
      2) use below formula for debounce time calculation:
         debounce = (DIV_ROUND_UP(debounce, 31) - 1) & 0xFF;

      This is because desc->lock is raw_spinlock and is held when 
chv_gpio_irq_ack()
      is called by the genirq core. chv_gpio_irq_ack() in turn takes pctrl->lock
      which in -rt is an rt-mutex causing might_sleep() rightfully to complain 
about
      sleeping function called from invalid context.

      In order to keep -rt happy but at the same time make sure that register
      accesses get serialized, convert the driver to use raw_spinlock instead.

      pinctrl: baytrail: Use raw_spinlock for locking

      The Intel Baytrail pinctrl driver implements irqchip callbacks which are

we

      This is because in -rt spinlocks are preemptible so taking the driver
      private spinlock in irqchip callbacks causes might_sleep() to trigger.

      In order to keep -rt happy but at the same time make sure that register
      accesses get serialized, convert the driver to use raw_spinlock instead.

      Also shorten the critical section a bit in few places.

      surface pro 3: Add support driver for Surface Pro 3 buttons

      Since Surface Pro 3 does not follow the specs of "Windows ACPI Design
      Guide for SoC Platform", code in drivers/input/misc/soc_array.c can
      not detect these buttons on it. According to bios implementation,
      Surface Pro 3 encapsulates these buttons in a device named "VGBI",
      with _HID "MSHW0028". When any of the buttons is pressed, a specify
      ACPI notification code for this button will be delivered to "VGBI". For
      example, if power button is pressed down, ACPI notification code of 0xc6
      will be sent by Notify(VGBI, 0xc6).

      This patch leverages "VGBI" to distinguish different ACPI notification
      code from Power button, Home button, Volume button, then dispatches these
      code to input layer. Lid is already covered by acpi button driver, so
      there's no need to rewrite.

      hp-wireless: remove unneeded goto/label in hpwl_init

      acpi_bus_register_driver() already returns an appropriate value (0 on
      success, and some negative value on error) to be used in __init functions
      so the goto/label is redundant in hpwl_init thus remove it and directly
      return the value

      ALSA: hda - Fix widget sysfs tree corruption after refresh

      When snd_hdac_refresh_widget_sysfs() is called before the first
      hda_widget_sysfs_init(), the next call overrides and eventually
      fails.  This results in unexpected Oops, something like:
        BUG: unable to handle kernel NULL pointer dereference at 
00000000000000c8
        IP: [<ffffffff8180e2a3>] hdmi_chmap_ctl_info+0x23/0x40

      The fix is to add a check of the existing sysfs tree.  Also, for more
      safety, this patch adds the checks of device_is_registered() in
      snd-hdac_refresh_wdiget_sysfs(), too.

      dmaengine: hdmac: Add memset capabilities

      Just like for the XDMAC, the SoCs that embed the HDMAC don't have any kind
      of GPU, and need to accelerate a few framebuffer-related operations 
through
      their DMA controller.

      However, unlike the XDMAC, the HDMAC doesn't have the memset capability
      built-in. That can be easily emulated though, by doing a transfer with a
      fixed address on the variable that holds the value we want to set.

      In commit 1e052be69d04 ("net_sched: destroy proto tp when all filters are

      for each tp, however, that is only done for root_ht, same is needed
      for others.

      This can be reproduced by the following tc commands:

      tc filter add dev eth0 parent 1:0 prio 5 handle 15: protocol ip u32 
divisor 256
      tc filter add dev eth0 protocol ip parent 1: prio 5 handle 15:2:2 u32

      net: fec: use reinit_completion() in mdio accessor functions

      Rather than re-initialising the entire completion on every mdio access,
      use reinit_completion() which only resets the completion count.  This
      avoids possible reinitialisation of the contained spinlock and waitqueue
      while they may be in use (eg, mid-completion.)

      Such an event could occur if there's a long delay in interrupt handling
      causing the mdio accessor to time out, then a second access comes in
      while the interrupt handler on a different CPU has called complete().
      Another scenario where this has been observed is while locking has
      been missing at the phy layer, allowing concurrent attempts to access
      the MDIO bus.

      net: phy: add locking to phy_read_mmd_indirect()/phy_write_mmd_indirect()

      The phy layer is missing locking for the above two functions - it
      has been observed that two threads (userspace and the phy worker
      thread) can race, entering the bus ->write or ->read functions
      simultaneously.

      This causes the FEC driver to initialise a completion while another
      thread is waiting on it or while the interrupt is calling complete()
      on it, which causes spinlock unlock-without-lock, spinlock lockups,
      and completion timeouts.

      RDS: Fix rds MR reference count in rds_rdma_unuse()

      rds_rdma_unuse() drops the mr reference count which it hasn't

      and then rdma_destroy_mr() it first, then rds_mr_put() to decrement
      its reference count. Whichever thread holds last reference will free
      the mr via rds_mr_put()

      vxlan: re-ignore EADDRINUSE from igmp_join

      Before 56ef9c909b40[1] it used to ignore all errors from igmp_join().
      That commit enhanced that and made it error out whatever error happened
      with igmp_join(), but that's not good because when using multicast
      groups vxlan will try to join it multiple times if the socket is reused
      and then the 2nd and further attempts will fail with EADDRINUSE.

      As we don't track to which groups the socket is already subscribed, it's
      okay to just ignore that error.

      r8169: Add values missing in @get_stats64 from HW counters

      The r8169 driver collects statistical information returned by
      @get_stats64 by counting them in the driver itself, even though many
      (but not all) of the values are already collected by tally counters
      (TCs) in the NIC.  Some of these TC values are not returned by
      @get_stats64.  Especially the received multicast packages are missing
      from /proc/net/dev.

      Rectify this by fetching the TCs and returning them from
      rtl8169_get_stats64.

      The counters collected in the driver obviously disappear as soon as the
      driver is unloaded so after a driver is loaded the counters always start
      at 0. The TCs on the other hand are only reset by a power cycle.  Without
      further considerations the values collected by the driver would not match
      up against the TC values.

      This patch introduces a new function rtl8169_reset_counters which
      resets the TCs.  Also, since rtl8169_reset_counters shares most of
      its code with rtl8169_update_counters, refactor the shared code into
      two new functions  rtl8169_map_counters and rtl8169_unmap_counters.

      Unfortunately chip versions prior to RTL_GIGA_MAC_VER_19 don't allow
      to reset the TCs programatically.  Therefore introduce an addition to
      the rtl8169_private struct and a function rtl8169_init_counter_offsets
      to store the TCs at first rtl_open.  Use these values as offsets in
      rtl8169_get_stats64.  Propagate a failure to reset *and* update the
      counters up to rtl_open and emit a warning message, if so.

      ACPICA: Disassembler: Cleanup acpi_gbl_db_opt_verbose acpiexec usage

      ACPICA commit 42d7ad7bfb1cfb95183c1386c77509f2036f521d

      When acpi_gbl_db_opt_verbose is used in acpi_dm_descending_op() (invoked 
by
      acpi_dm_disassemble()), it is actually exported by the disassembler but 
used
      by the debugger to distinguish the output of the disassembler for 
different
      debugger commands. It is by default TRUE but is set to FALSE for control
      method disassembly command - "disassemble". So it's initialization should
      be a part of the ACPI_DISASSEMBLER conditioned code. This patch uses
      ACPI_INIT_GLOBAL to achieve a clean manner so that when ACPI_DISASSEMBLER
      is not defined, ACPI_DEBUGGER conditioned code needn't link to this 
option.
      Since it is a disassembler exported variable, it is renamed to
      acpi_gbl_dm_opt_Verbose in this patch.

      As VERBOSE_PRINT() macro has only one user, this patch also removes the
      definition of this macro. Lv Zheng.

      This patch doesn't affect Linux kernel.

      ACPICA: Disassembler: Cleanup acpi_gbl_db_opt_disasm

      ACPICA commit 969989cf7f85e2a2a0cd048cd25fc706246a48a2

      This patch cleans up the following global variable - 
acpi_gbl_db_opt_disasm:
      The setting is used to control the full disassembly feature for iasl. ACPI
      debugger (acpiexec) shall have nothing to do with it. Actually, acpiexec
      never links to ad_aml_disassemble().

      This patch thus renames this global option to acpi_gbl_dm_opt_disasm and
      removes all acpiexec and debugger references on it. Lv Zheng.

      ACPICA: Debugger: Split debugger initialization/termination APIs

      ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432

      It is likely that the debugger is enabled only when a userspace program
      explicitly tells a kernel to do so, so it shouldn't be initialized as
      early as current implementation.

      The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to 
call
      the new APIs by itself. And BSD developers may also get notified to invoke
      the APIs for DDB enabling. Lv Zheng.

      This patch doesn't affect Linux kernel as debugger is currently not 
enabled
      in the Linux kernel.

      ACPICA: Tables: Fix global table list issues by removing fixed table 
indexes

      ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941

      The fixed table indexes leave holes in the global table list:
       1. One hole can be seen when there is only 1 FACS provided by the BIOS.
       2. Tow holes can be seen when it is a reduced hardware platform.
      The holes do not break OSPMs but have broken ACPI debugger "tables"
      command.

      Also the "fixed table indexes" mechanism may make the descriptors of the
      standard tables installed earlier than DSDT to be overwritten by the
      descriptors of the fixed tables. For example, FACP disappears from the
      global table list after DSDT is installed.

      This patch fixes all above issues by removing the "fixed table indexes"
      mechanism which is too complicated to be maintained in a regression safe
      manner. After removal, the table loader will determine the indexes of the
      fixed tables. Lv Zheng.

      ppp: implement x-netns support

      Let packets move from one netns to the other at PPP encapsulation and
      decapsulation time.

      PPP units and channels remain in the netns in which they were
      originally created. Only the net_device may move to a different
      namespace. Cross netns handling is thus transparent to lower PPP
      layers (PPPoE, L2TP, etc.).

      PPP devices are automatically unregistered when their netns gets
      removed. So read() and poll() on the unit file descriptor will
      respectively receive EOF and POLLHUP. Channels aren't affected.

      net/mlx5e: Avoid accessing NULL pointer at ndo_select_queue

      To avoid multiply/division operations on the data path,
      we hold a {channel, tc}==>txq mapping table.
      We held this mapping table inside the channel object that is
      being destroyed upon some configuration operations (e.g MTU change).
      So in case ndo_select_queue occurs during such a configuration operation,
      it may access a NULL channel pointer, resulting in kernel panic.
      To fix this issue we moved the {channel, tc}==>txq mapping table
      outside the channel object so that it will be available also
      during such configuration operations.

      mtip32x: fix regression introduced by blk-mq per-hctx flush

      Hi,

      After commit f70ced091707 (blk-mq: support per-distpatch_queue flush
      machinery), the mtip32xx driver may oops upon module load due to walking
      off the end of an array in mtip_init_cmd.  On initialization of the
      flush_rq, init_request is called with request_index >= the maximum queue
      depth the driver supports.  For mtip32xx, this value is used to index
      into an array.  What this means is that the driver will walk off the end
      of the array, and either oops or cause random memory corruption.

      The problem is easily reproduced by doing modprobe/rmmod of the mtip32xx
      driver in a loop.  I can typically reproduce the problem in about 30
      seconds.

      Now, in the case of mtip32xx, it actually doesn't support flush/fua, so
      I think we can simply return without doing anything.  In addition, no
      other mq-enabled driver does anything with the request_index passed into
      init_request(), so no other driver is affected.  However, I'm not really
      sure what is expected of drivers.  Ming, what did you envision drivers
      would do when initializing the flush requests?

      RDS: Assorted bug fixes

      We would like to improve RDS upstream support and in that context, I
      started playing with it.  But run into number of issues including as
      basic is RDS IB RDMA doesn't work. As part of the debug, I ended up
      creating the $subject series which has bunch of assorted fixes. At
      least with this series I can run RDS IB RDMA and other tests
      successfully.

      Some of these fixes have been done by Chris Meson, Andy Grover and
      Zach Brown while at Oracle. There are still more kinks with FMR and
      error handling and I plan to address them in a follow up series.

      RDS: return EMSGSIZE for oversize requests before processing/queueing

      rds_send_queue_rm() allows for the "current datagram" being queued
      to exceed SO_SNDBUF thresholds by checking bytes queued without
      counting in length of current datagram. (Since sk_sndbuf is set
      to twice requested SO_SNDBUF value as a kernel heuristic this
      is usually fine!)

      If this "current datagram" squeezing past the threshold is itself
      many times the size of the sk_sndbuf threshold itself then even
      twice the SO_SNDBUF does not save us and it gets queued but
      cannot be transmitted. Threads block and deadlock and device
      becomes unusable. The check for this datagram not exceeding
      SNDBUF thresholds (EMSGSIZE) is not done on this datagram as
      that check is only done if queueing attempt fails.
      (Datagrams that follow this datagram fail queueing attempts, go
      through the check and eventually trip EMSGSIZE error but zero
      length datagrams silently fail!)

      This fix moves the check for datagrams exceeding SNDBUF limits
      before any processing or queueing is attempted and returns EMSGSIZE
      early in the rds_sndmsg() code. This change also ensures that all
      datagrams get checked for exceeding SNDBUF/sk_sndbuf size limits
      and the large datagrams that exceed those limits do not get to
      rds_send_queue_rm() code for processing.

      RDS: make sure rds_send_drop_to properly takes the m_rs_lock

      rds_send_drop_to() is used during socket tear down to find all the
      messages on the socket and flush them .  It can race with the
      acking code unless it takes the m_rs_lock on each and every message.

      This plugs a hole where we didn't take m_rs_lock on any message that
      didn't have the RDS_MSG_ON_CONN set.  Taking m_rs_lock avoids
      double frees and other memory corruptions as the ack code trusts
      the message m_rs pointer on a socket that had actually been freed.

      We must take m_rs_lock to access m_rs.  Because of lock nesting and
      rs access, we also need to acquire rs_lock.

      RDS: Make sure we do a signaled send for large-send

      WR(Work Requests )always generate a WC(Work Completion) with
      signaled send. Default RDS ib code is setup for un-signaled
      completion. Since RDS connction is persistent, we can end up
      sending the data even after large-send when the remote end is
      not active(for any reason).

      By doing  a signaled send at least once per large-send,
      we can at least detect the problem in work completion
      handler there by avoiding sending more data to
      inactive remote.

      RDS: always free recv frag as we free its ring entry

      We were still seeing rare occurrences of the WARN_ON(recv->r_frag) which
      indicates that the recv refill path was finding allocated frags in ring

      They only seem to be occurring in the presence of completion errors and
      connection resets.

      This patch ensures that we free the frag as we mark the ring entry free.
      This should stop the refill path from finding allocated frags in ring
      entries that were marked free.

      writeback: sync_inodes_sb() must write out I_DIRTY_TIME inodes and always 
call wait_sb_inodes()

      e79729123f63 ("writeback: don't issue wb_writeback_work if clean")
      updated writeback path to avoid kicking writeback work items if there
      are no inodes to be written out; unfortunately, the avoidance logic
      was too aggressive and broke sync_inodes_sb().

      * sync_inodes_sb() must write out I_DIRTY_TIME inodes but I_DIRTY_TIME
        inodes dont't contribute to bdi/wb_has_dirty_io() tests and were
        being skipped over.

      * inodes are taken off wb->b_dirty/io/more_io lists after writeback
        starts on them.  sync_inodes_sb() skipping wait_sb_inodes() when
        bdi_has_dirty_io() breaks it by making it return while writebacks
        are in-flight.

      This patch fixes the breakages by

      * Removing bdi_has_dirty_io() shortcut from bdi_split_work_to_wbs().
        The callers are already testing the condition.

      * Removing bdi_has_dirty_io() shortcut from sync_inodes_sb() so that
        it always calls into bdi_split_work_to_wbs() and wait_sb_inodes().

      * Making bdi_split_work_to_wbs() consider the b_dirty_time list for
        WB_SYNC_ALL writebacks.

      regulator: lp872x: use the private data instead of updating I2C device 
platform data

      Currently, lp872x driver parses the DT and copies values into the
      'cl->dev.platform_data' if 'of_node' exists.
      This may have architectural issue. Platform data is configurable through
      the DT or I2C board info inside the platform area.
      However, lp872x driver changes this configuration when it is loaded.

      The lp872x driver should get data from the platform side and use the 
private
      data, 'lp872x->pdata' instead of changing the original platform data.

      tcp: refine pacing rate determination

      When TCP pacing was added back in linux-3.12, we chose
      to apply a fixed ratio of 200 % against current rate,
      to allow probing for optimal throughput even during
      slow start phase, where cwnd can be doubled every other gRTT.

      At Google, we found it was better applying a different ratio
      while in Congestion Avoidance phase.
      This ratio was set to 120 %.

      We've used the normal tcp_in_slow_start() helper for a while,
      then tuned the condition to select the conservative ratio
      as soon as cwnd >= ssthresh/2 :

      - After cwnd reduction, it is safer to ramp up more slowly,
        as we approach optimal cwnd.
      - Initial ramp up (ssthresh == INFINITY) still allows doubling
        cwnd every other RTT.

      phylib: Make PHYs children of their MDIO bus, not the bus' parent.

      commit 18ee49ddb0d2 ("phylib: rename mii_bus::dev to mii_bus::parent")
      changed the parent of PHY devices from the bus to the bus parent.

      Then, commit 4dea547fef1b ("phylib: rework to prepare for OF
      registration of PHYs") moved the code into phy_device.c

      At this point, it is somewhat unclear why the change was seen as
      necessary.  But, when we look at the device model tree in
      /sys/devices, it is clearly incorrect.  The PHYs should be children of
      their MDIO bus.

      Change the PHY's parent device to be the MDIO bus device.

      tcp: fix slow start after idle vs TSO/GSO

      slow start after idle might reduce cwnd, but we perform this
      after first packet was cooked and sent.

      With TSO/GSO, it means that we might send a full TSO packet
      even if cwnd should have been reduced to IW10.

      Moving the SSAI check in skb_entail() makes sense, because
      we slightly reduce number of times this check is done,
      especially for large send() and TCP Small queue callbacks from
      softirq context.

      As Neal pointed out, we also need to perform the check
      if/when receive window opens.

      Tested:

      Following packetdrill test demonstrates the problem
      // Test of slow start after idle

      `sysctl -q net.ipv4.tcp_slow_start_after_idle=1`

      ASoC: arizona: Poll for FLL clock OK rather than use interrupts

      The extcon driver takes the DAPM mutex from within the interrupt thread
      in several places, which makes it possible to get into a situation where
      the interrupt thread is blocked waiting on the DAPM mutex whilst a DAPM
      sequence is running which is attempting to configure the FLL. In this
      case the FLL completion can't be completed as as the IRQ handler is
      ONE_SHOT, which cause the FLL lock to use the full time out (250mS) and
      report that the process timed out.

      It is not really practical to make the extcon driver not take the DAPM
      mutex from within the interrupt thread, at least not without extensive
      modification. So this patch fixes the issue by switching the wait for
      the FLL lock to polling. A few fast polls are done first as the FLL
      should lock quickly for a good quality reference clock, (indeed it hits
      on the first poll on my system) and it will poll every 20mS after that
      until it times out.

      Docs: dt: add generic MSI bindings

      Currently msi-parent is used in a couple of drivers despite being fairly
      underspecified. This patch adds a generic binding for MSIs (including
      the existing msi-parent property) enabling the description of platform
      devices capable of using MSIs.

      While MSIs are primarily distinguished by doorbell and payload, some MSI
      controllers (e.g. the GICv3 ITS) also use side-band information
      accompanying the write to identify the master which originated the MSI,
      to allow for sandboxing. This sideband information is non-probeable and
      needs to be described in the DT. Other MSI controllers may have
      additional configuration details which need to be described per-master.

      This patch adds a generic msi-parent binding document, extending the
      de-facto standard with a new (optional) #msi-cells which can be used to
      express any per-master configuration and/or sideband data. This is
      sufficient to describe non-hotpluggable devices.

      For busses where sideband data may be derived from some bus-specific
      master ID scheme, other properties will be required to describe the
      mapping.

      drivercore: Fix unregistration path of platform devices

      The unregister path of platform_device is broken. On registration, it
      will register all resources with either a parent already set, or
      type==IORESOURCE_{IO,MEM}. However, on unregister it will release
      everything with type==IORESOURCE_{IO,MEM}, but ignore the others. There
      are also cases where resources don't get registered in the first place,
      like with devices created by of_platform_populate()*.

      Fix the unregister path to be symmetrical with the register path by
      checking the parent pointer instead of the type field to decide which
      resources to unregister. This is safe because the upshot of the
      registration path algorithm is that registered resources have a parent
      pointer, and non-registered resources do not.

      * It can be argued that of_platform_populate() should be registering
        it's resources, and they argument has some merit. However, there are
        quite a few platforms that end up broken if we try to do that due to
        overlapping resources in the device tree. Until that is fixed, we need
        to solve the immediate problem.

      of/address: Don't loop forever in of_find_matching_node_by_address().

      If the internal call to of_address_to_resource() fails, we end up
      looping forever in of_find_matching_node_by_address().  This can be
      caused by a defective device tree, or calling with an incorrect
      matches argument.

      Fix by calling of_find_matching_node() unconditionally at the end of
      the loop.

      of/platform: add function to populate default bus

      When a default bus like the simple-bus should be used someone had to
      call of_platform_populate() with the default match table. This match
      table was not exported, so it is impossible for code build as a module
      to use this. Instead of exporting of_default_bus_match_table, add a new
      function which uses this default match table and populates the bus.

      regulator: isl9305: Export OF module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
      regardless of the mechanism that was used to register the device
      (i.e: OF or board code) and the table that is used later to match
      the driver with the device (i.e: I2C id table or OF match table).

      So drivers needs to export the I2C id table and this be built into
      the module or udev won't have the necessary information to autoload
      the needed driver module when the device is added.

      But this means that OF-only drivers needs to have both OF and I2C id
      tables that have to be kept in sync and also the dev node compatible
      manufacturer prefix is stripped when reporting the MODALIAS. Which can
      lead to issues if two vendors use the same I2C device name for example.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an SPI device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table even when
      is unused now to prevent breaking module loading when the core changes.

      ARM: mm: improve do_ldrd_abort macro

      Improve the do_ldrd_abort macro code - firstly, it inefficiently checks
      for the LDRD encoding by doing a multi-stage test of various bits.  This
      can be simplified by generating a mask, bitmasking the instruction and
      then comparing the result.

      Secondly, we want to be able to test the result rather than branching
      to do_DataAbort, so remove the branch at the end and rename the macro
      to 'teq_ldrd' to reflect it's new usage.  teq_ldrd macro returns 'eq'
      if the instruction was a LDRD.

      pinctrl: zynq: Fix typos in smc0_nand_grp and smc0_nor_grp

      Group names should be smc0_nand_grp and smc0_nor_grp, otherwise you'll
      get errors like this if you try to pinmux them via the devicetree:
      zynq-pinctrl 700.pinctrl: invalid group "smc0_nand_grp" for function 
"smc0_nand"

      Probably a typo while creating these tables.

      Host platforms such as routers supported by OpenWRT can
      support NVRAM reading directly from internal NVRAM store.
      With this patch the nvram load routines will fall back to
      this method when there is no nvram file and support is

      brcmfmac: bump highest event number for 4339 firmware

      The event mask length is determined by the highest event number
      that is specified in the driver. When this length is shorter than
      firmware expects setting event mask will fail and device becomes
      pretty useless. This issue was reported with bcm4339 firmware that

      brcmf_flowring_block blocks the last active flowring under the same
      interface instead of the one provided by caller. This could lead to a
      dead lock of netif stop if there are more than one flowring under the

      not unblock the ring right away.

      291          * We timed out waiting for the noisefloor to load, probably

      sched: Fix cpu_active_mask/cpu_online_mask race

      There is a race condition in SMP bootup code, which may result
      in

          WARNING: CPU: 0 PID: 1 at kernel/workqueue.c:4418
          workqueue_cpu_up_callback()
      or
          kernel BUG at kernel/smpboot.c:135!

      It can be triggered with a bit of luck in Linux guests running
      on busy hosts.

        CPU0                        CPUn
        ====                        ====

        _cpu_up()
          __cpu_up()
                                    start_secondary()
                                      set_cpu_online()
                                        cpumask_set_cpu(cpu,
                                                   to_cpumask(cpu_online_bits));
          cpu_notify(CPU_ONLINE)
            <do stuff, see below>
                                        cpumask_set_cpu(cpu,
                                                   to_cpumask(cpu_active_bits));

      During the various CPU_ONLINE callbacks CPUn is online but not
      active. Several things can go wrong at that point, depending on
      the scheduling of tasks on CPU0.

      Variant 1:

        cpu_notify(CPU_ONLINE)
          workqueue_cpu_up_callback()
            rebind_workers()
              set_cpus_allowed_ptr()

        This call fails because it requires an active CPU; rebind_workers()
        ends with a warning:

          WARNING: CPU: 0 PID: 1 at kernel/workqueue.c:4418
          workqueue_cpu_up_callback()

      Variant 2:

        cpu_notify(CPU_ONLINE)
          smpboot_thread_call()
            smpboot_unpark_threads()
             ..
              __kthread_unpark()
                __kthread_bind()
                wake_up_state()
                 ..
                  select_task_rq()
                    select_fallback_rq()

        The ->wake_cpu of the unparked thread is not allowed, making a call
        to select_fallback_rq() necessary. Then, select_fallback_rq() cannot
        find an allowed, active CPU and promptly resets the allowed CPUs, so
        that the task in question ends up on CPU0.

        When those unparked tasks are eventually executed, they run
        immediately into a BUG:

          kernel BUG at kernel/smpboot.c:135!

      Just changing the order in which the online/active bits are set
      (and adding some memory barriers), would solve the two issues
      above. However, it would change the order of operations back to
      the one before commit 6acbfb96976f ("sched: Fix hotplug vs.
      set_cpus_allowed_ptr()"), thus, reintroducing that particular
      problem.

      Going further back into history, we have at least the following
      commits touching this topic:
      - commit 2baab4e90495 ("sched: Fix select_fallback_rq() vs 
cpu_active/cpu_online")
      - commit 5fbd036b552f ("sched: Cleanup cpu_active madness")

      Together, these give us the following non-working solutions:

        - secondary CPU sets active before online, because active is assumed to
          be a subset of online;

        - secondary CPU sets online before active, because the primary CPU
          assumes that an online CPU is also active;

        - secondary CPU sets online and waits for primary CPU to set active,
          because it might deadlock.

      Commit 875ebe940d77 ("powerpc/smp: Wait until secondaries are
      active & online") introduces an arch-specific solution to this
      arch-independent problem.

      Now, go for a more general solution without explicit waiting and
      simply set active twice: once on the secondary CPU after online
      was set and once on the primary CPU after online was seen.

      iommu/vt-d: Really use upper context table when necessary

      There is a bug in iommu_context_addr() which will always use
      the lower context table, even when the upper context table
      needs to be used. Fix this issue.

      ARM: entry: ensure that IRQs are enabled when calling syscall_trace_exit()

      The audit code looks like it's been written to cope with being called
      with IRQs enabled.  However, it's unclear whether IRQs should be
      enabled or disabled when calling the syscall tracing infrastructure.

      Right now, sometimes we call this with IRQs enabled, and other times
      with IRQs disabled.  Opt for IRQs being enabled for consistency.

      ARM: entry: efficiency cleanups

      Make the "fast" syscall return path fast again.  The addition of IRQ
      tracing and context tracking has made this path grossly inefficient.
      We can do much better if these options are enabled if we save the
      syscall return code on the stack - we then don't need to save a bunch
      of registers around every single callout to C code.

      drivers/video/fbdev/vt8623fb: Use arch_phys_wc_add() and pci_iomap_wc()

      This driver uses the same area for MTRR as for the ioremap().

      Convert the driver from using the x86-specific MTRR code to the
      architecture-agnostic arch_phys_wc_add(). It will avoid MTRRs if
      write-combining is available. In order to take advantage of that
      also ensure the ioremapped area is requested as write-combining.

      There are a few motivations for this:

      a) Take advantage of PAT when available.

      b) Help bury MTRR code away, MTRR is architecture-specific and on
         x86 it is being replaced by PAT.

      c) Help with the goal of eventually using _PAGE_CACHE_UC over
         _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
         de33c442e titled "x86 PAT: fix performance drop for glx,
         use UC minus for ioremap(), ioremap_nocache() and
         pci_mmap_page_range()").

      The conversion done is expressed by the following Coccinelle
      SmPL patch, it additionally required manual intervention to
      address all the ifdeffery and removal of redundant things which
      arch_phys_wc_add() already addresses such as verbose message
      about when MTRR fails and doing nothing when we didn't get an

      PCI: Add pci_iomap_wc() variants

      PCI BARs tell us whether prefetching is safe, but they don't say
      anything about write combining (WC). WC changes ordering rules
      and allows writes to be collapsed, so it's not safe in general
      to use it on a prefetchable region.

      Add pci_iomap_wc() and pci_iomap_wc_range() so drivers can take
      advantage of write combining when they know it's safe.

      On architectures that don't fully support WC, e.g., x86 without
      PAT, drivers for legacy framebuffers may get some of the benefit
      by using arch_phys_wc_add() in addition to pci_iomap_wc().  But
      arch_phys_wc_add() is unreliable and should be avoided in
      general.  On x86, it uses MTRRs, which are limited in number and
      size, so the results will vary based on driver loading order.

      The goals of adding pci_iomap_wc() are to:

      - Give drivers an architecture-independent way to use WC so they can stop
        using interfaces like mtrr_add() (on x86, pci_iomap_wc() uses
        PAT when available).

      - Move toward using _PAGE_CACHE_MODE_UC, not _PAGE_CACHE_MODE_UC_MINUS,
        on x86 on ioremap_nocache() (see de33c442ed2a ("x86 PAT: fix
        performance drop for glx, use UC minus for ioremap(), ioremap_nocache()
        and pci_mmap_page_range()").

      drivers/video/fbdev/gxt4500: Use pci_ioremap_wc_bar() to map framebuffer

      The driver doesn't use mtrr_add() or arch_phys_wc_add() but
      since we know the framebuffer is isolated already on an
      ioremap() we can take advantage of write combining for
      performance where possible.

      In this case there are a few motivations for this:

      a) Take advantage of PAT when available.

      b) Help with the goal of eventually using _PAGE_CACHE_UC over
         _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
         de33c442e titled "x86 PAT: fix performance drop for glx,
         use UC minus for ioremap(), ioremap_nocache() and
         pci_mmap_page_range()").

      drivers/video/fbdev/kyrofb: Use arch_phys_wc_add() and 
pci_ioremap_wc_bar()

      Convert the driver from using the x86-specific MTRR code to the
      architecture-agnostic arch_phys_wc_add(). It will avoid MTRR if
      write-combining is available, in order to take advantage of that
      also ensure the ioremapped area is requested as write-combining.

      There are a few motivations for this:

      a) Take advantage of PAT when available

      b) Help bury MTRR code away, MTRR is architecture-specific and on
         x86 it is being replaced by PAT.

      c) Help with the goal of eventually using _PAGE_CACHE_UC over
         _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
         de33c442e titled "x86 PAT: fix performance drop for glx,
         use UC minus for ioremap(), ioremap_nocache() and
         pci_mmap_page_range()")

      The conversion done is expressed by the following Coccinelle
      SmPL patch, it additionally required manual intervention to
      address all the ifdeffery and removal of redundant things which
      arch_phys_wc_add() already addresses such as verbose message
      about when MTRR fails and doing nothing when we didn't get an
      MTRR.

      x86/mm: Make kernel/check.c explicitly non-modular

      The Kconfig currently controlling compilation of this code is:

        arch/x86/Kconfig:config X86_CHECK_BIOS_CORRUPTION
        arch/x86/Kconfig:       bool "Check for low memory corruption"

      ...meaning that it currently is not being built as a module by
      anyone.

      Lets remove the couple traces of modularity so that when reading
      the code there is no doubt it is builtin-only.

      Since module_init translates to device_initcall in the
      non-modular case, the init ordering remains unchanged with this
      commit.

      x86/platform: Make atom/pmc_atom.c explicitly non-modular

      The Kconfig currently controlling compilation of this code is:

      config PMC_ATOM
              def_bool y

      ...meaning that it currently is not being built as a module by
      anyone.

      Lets remove the couple traces of modularity so that when reading
      the driver there is no doubt it is builtin-only.

      Since module_init() translates to device_initcall() in the
      non-modular case, the init ordering remains unchanged with this
      commit.

      We leave some tags like MODULE_AUTHOR() for documentation
      purposes.

      Also note that MODULE_DEVICE_TABLE() is a no-op for non-modular
      code. We correct a comment that indicates the data was only used
      by that macro, as it actually is used by the code directly.

      backlight: tosa: Export I2C module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
      regardless of the mechanism that was used to register the device
      (i.e: OF or board code) and the table that is used later to match
      the driver with the device (i.e: I2C id table or OF match table).

      So drivers needs to export the I2C id table and this be built into
      the module or udev won't have the necessary information to autoload
      the needed driver module when the device is added.

      ALSA: hda - Refresh sysfs at snd_hda_codec_update_widgets()

      In the commit [fa4f18b4f402: ALSA: hda - Refresh widgets sysfs at
      probing Haswell+ HDMI codecs], snd_hdac_refresh_widget_sysfs() is
      explicitly called in the codec driver.  But this results in refreshing
      twice, as snd_hdac_refresh_widget_sysfs() itself calls
      snd_hdac_refresh_widgets() function.

      Instead, we can replace the call in snd_hda_codec_update_widgets()
      with snd_hdac_refresh_widget_sysfs().  This also fixes the missing
      sysfs update for ca0132, too.

      can: pcan_usb: don't provide CAN FD bittimings by non-FD adapters

      The CAN FD data bittiming constants are provided via netlink only when 
there
      are valid CAN FD constants available in priv->data_bittiming_const.

      Due to the indirection of pointer assignments in the peak_usb driver the
      priv->data_bittiming_const never becomes NULL - not even for non-FD 
adapters.

      The data_bittiming_const points to zero'ed data which leads to this result
      when running 'ip -details link show can0':

      35: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN mode DEFAULT group

      This patch changes the struct peak_usb_adapter::bittiming_const and struct
      peak_usb_adapter::data_bittiming_const to pointers to fix the assignemnt

      ALSA: hda - Fix path power activation

      The widget power-saving code tries to turn up/down the power of each
      widget in the I/O paths that are modified at each jack plug/unplug.
      The recent report revealed that the power activation leaves some
      widgets unpowered after plugging.  This is because
      snd_hda_activate_path() turns on path->active flag at the end of the
      function while the path power management is done before that.  Then
      it's regarded as if nothing is active, and the driver turns off the
      power.

      The fix is simply to set the flag at the beginning of the function,
      before trying to power up.

      ACPI: Decouple ACPI idle and ACPI processor drivers

      This patch introduces a new Kconfig symbol, ACPI_PROCESSOR_IDLE,
      which is auto selected by architectures which support the ACPI
      based C states for CPU Idle management.

      The processor_idle driver in its present form contains declarations
      specific to X86 and IA64. Since there are no reasonable defaults
      for other architectures e.g. ARM64, the driver is selected only for
      X86 or IA64.

      This helps in decoupling the ACPI processor_driver from the ACPI
      processor_idle driver which is useful for the upcoming alternative
      patchwork for controlling CPU Performance (CPPC) and CPU Idle (LPI).

      ACPI: Split out ACPI PSS from ACPI Processor driver

      The ACPI processor driver is currently tied too closely
      to the ACPI P-states (PSS) and other related constructs
      for controlling CPU performance.

      The newer ACPI specification (v5.1 onwards) introduces
      alternative methods to PSS. These new mechanisms are
      described within each ACPI Processor object and so they
      need to be scanned whenever a new Processor object is detected.
      This patch introduces a new Kconfig symbol to allow for
      finer configurability among the two options for controlling
      performance states. There is no change in functionality and
      the option is auto-selected by the architectures which support it.

      A future commit will introduce support for CPPC: A newer method of
      controlling CPU performance. The OS is not expected to support
      CPPC and PSS at the same time, so the Kconfig option lets us make
      the two mutually exclusive at compile time.

      xfs: Fix file type directory corruption for btree directories

      Users have occasionally reported that file type for some directory
      entries is wrong. This mostly happened after updating libraries some
      libraries. After some debugging the problem was traced down to
      xfs_dir2_node_replace(). The function uses args->filetype as a file type
      to store in the replaced directory entry however it also calls
      xfs_da3_node_lookup_int() which will store file type of the current
      directory entry in args->filetype. Thus we fail to change file type of a
      directory entry to a proper type.

      Fix the problem by storing new file type in a local variable before
      calling xfs_da3_node_lookup_int().

      xfs: lockdep annotations throw warnings on non-debug builds

      SO, now if we enable lockdep without enabling CONFIG_XFS_DEBUG,
      the lockdep annotations throw a warning because the assert that uses
      the lockdep define is not built in:

      fs/xfs/xfs_inode.c:367:1: warning: 'xfs_lockdep_subclass_ok' defined but 
not used [-Wunused-function]
          xfs_lockdep_subclass_ok(

      So now we need to create an ifdef mess to sort this all out, because
      we need to handle all the combinations of CONFIG_XFS_DEBUG=[y|n],
      CONFIG_XFS_WARNING=[y|n] and CONFIG_LOCKDEP=[y|n] appropriately.

      xfs: Fix uninitialized return value in xfs_alloc_fix_freelist()

      xfs_alloc_fix_freelist() can sometimes jump to out_agbp_relse
      without ever setting value of 'error' variable which is then
      returned. This can happen e.g. when pag->pagf_init is set but AG is
      for metadata and we want to allocate user data.

      Fix the problem by initializing 'error' to 0, which is the desired
      return value when we decide to skip this group.

      clk: rockchip: register pll mux before pll itself

      The structure is xin24m -> pll -> pll-mux (xin24m,pll,xin32k). The pll
      does have an init callback to make sure the boot-selected frequency is
      using the expected pll settings and resets the same frequency using
      the values provided in the driver if necessary.

      The setting itself also involves remuxing the pll-mux temporarily to
      the xin24m source to let the new pll rate settle. Until now this worked
      flawlessly, even when it had the flaw of accessing the mux settings
      before the mux actually got registered.

      With the recent clock-core conversions this flaw became apparent in
      null pointer dereference in
      [<c03fc400>] (clk_hw_get_num_parents) from [<c0400df0>] 
(clk_mux_get_parent+0x14/0xc8)
      [<c0400ddc>] (clk_mux_get_parent) from [<c040246c>] 
(rockchip_rk3066_pll_set_rate+0xd8/0x320)

      So to fix that, simply register the pll-mux before the pll, so that
      it will be fully initialized when the pll clock executes its init-
      callback and possibly touches the pll-mux clock.

      clk: Hi6220: add stub clock driver

      On Hi6220, there have some clocks which can use mailbox channel to send
      messages to power controller to change frequency; this includes CPU, GPU
      and DDR clocks.

      For dynamic frequency scaling, firstly need write the frequency value to
      SRAM region, and then send message to mailbox to trigger power controller
      to handle this requirement. This driver will use syscon APIs to pass SRAM
      memory region and use common mailbox APIs for channels accessing.

      This init driver will support cpu frequency change firstly.

      f2fs: fix to release inode correctly

      In following call stack, if unfortunately we lose all chances to truncate
      inode page in remove_inode_page, eventually we will add the nid allocated
      previously into free nid cache, this nid is with NID_NEW status and with
      NEW_ADDR in its blkaddr pointer:

       - f2fs_create
        - f2fs_add_link
         - __f2fs_add_link
          - init_inode_metadata
           - new_inode_page
            - new_node_page
             - set_node_addr(, NEW_ADDR)
           - f2fs_init_acl   failed
           - remove_inode_page  failed
        - handle_failed_inode
         - remove_inode_page  failed
         - iput
          - f2fs_evict_inode
           - remove_inode_page  failed
           - alloc_nid_failed   cache a nid with valid blkaddr: NEW_ADDR

      This may not only cause resource leak of previous inode, but also may 
cause
      incorrect use of the previous blkaddr which is located in NO.nid node 
entry
      when this nid is reused by others.

      This patch tries to add this inode to orphan list if we fail to truncate
      inode, so that we can obtain a second chance to release it in orphan
      recovery flow.

      batman-adv: Annotate deleting functions with external lock via lockdep

      Functions which use (h)list_del* are requiring correct locking when they
      operate on global lists. Most of the time the search in the list and the
      delete are done in the same function. All other cases should have it
      visible that they require a special lock to avoid race conditions.

      Lockdep asserts can be used to check these problem during runtime when the
      lockdep functionality is enabled.

      batman-adv: Fix gw_bandwidth calculation on 32 bit systems

      The TVLV for the gw_bandwidth stores everything as u32. But the
      gw_bandwidth reads the signed long which limits the maximum value to
      (2 ** 31 - 1) on systems with 4 byte long. Also the input value is always
      converted from either Mibit/s or Kibit/s to 100Kibit/s. This reduces the
      values even further when the user sets it via the default unit Kibit/s. It
      may even cause an integer overflow and end up with a value the user never
      intended.

      Instead read the values as u64, check for possible overflows, do the unit
      adjustments and then reduce the size to u32.

      In pfkey_sendmsg the net mutex is taken and then pfkey_broadcast takes
      the RCU lock.

      Since pfkey_broadcast takes the RCU lock the allocation argument is
      pointless since GFP_ATOMIC must be used between the rcu_read_{,un}lock.
      The one call outside of rcu can be done with GFP_KERNEL.

      TSC packets.  A CYC packet contains the number of CPU cycles since the
      last CYC packet. Unlike MTC and TSC packets, CYC packets are only sent
      when another packet is also sent.

      Support for this feature is indicated by:

      /sys/bus/event_source/devices/intel_pt/caps/psb_cyc

      which contains "1" if the feature is supported and "0" otherwise.

      CYC packets can be requested using a PMU config term e.g. perf record -e
      intel_pt/cyc/u sleep 1

      The frequency of CYC packets can also be specified.  e.g. perf record -e
      intel_pt/cyc,cyc_thresh=2/u sleep 1

      CYC packets are not requested by default.

      Valid cyc_thresh values are given by:

      /sys/bus/event_source/devices/intel_pt/caps/cycle_thresholds

      which contains a hexadecimal value, the bits of which represent valid
      values e.g. bit 2 set means value 2 is valid.

      The value represents the minimum number of CPU cycles that must have
      passed before a CYC packet can be sent.  The number of CPU cycles is:

          2 ^ (value - 1)

      e.g. value 4 means 8 CPU cycles must pass before a CYC packet can be
      sent.  Note a CYC packet is still only sent when another packet is sent,
      not at, e.g. every 8 CPU cycles.

      If an invalid value is entered, the error message will give a list of
      valid values e.g.

          $ perf record -e intel_pt/cyc,cyc_thresh=15/u uname
          Invalid cyc_thresh for intel_pt. Valid values are: 0-12

      tools/perf/Documentation/intel-pt.txt is updated in a later patch as
      there are a number of new features being added.

      perf tools: Add Intel PT support for decoding CYC packets

      CYC packets provide even finer grain timestamp information than MTC and
      TSC packets.  A CYC packet contains the number of CPU cycles since the
      last CYC packet.

      This patch just adds decoder support.  The CPU frequency can be related
      to TSC using the Maximum Non-Turbo Ratio in combination with the CBR
      (core-to-bus ratio) packet.  However more accuracy is achieved by simply
      interpolating the number of cycles between other timing packets like MTC
      or TSC.  This patch takes the latter approach.

      Support for a default value and validation of values is provided by a
      later patch. Also documentation is updated in a separate patch.

      For details refer to the June 2015 or later Intel 64 and IA-32

      perf tools: Add Intel PT support for using MTC packets

      MTC packets are a new Intel PT feature.

      MTC packets provide finer grain timestamp information than TSC packets.

      Support for this feature is indicated by:

        /sys/bus/event_source/devices/intel_pt/caps/mtc

      which contains "1" if the feature is supported and "0" otherwise.

      intel_pt/mtc/u sleep 1

      The frequency of MTC packets can also be specified.  e.g. perf record -e
      intel_pt/mtc,mtc_period=2/u sleep 1

      The default value is 3 or the nearest lower value that is supported.  0
      is always supported.

      Valid values are given by:

      /sys/bus/event_source/devices/intel_pt/caps/mtc_periods

      which contains a hexadecimal value, the bits of which represent valid
      values e.g. bit 2 set means value 2 is valid.

      The value is converted to the MTC frequency as:

        CTC-frequency / (2 ^ value)

      e.g. value 3 means one eighth of CTC-frequency

      Where CTC is the hardware crystal clock, the frequency of which can be
      related to TSC via values provided in cpuid leaf 0x15.

      If an invalid value is entered, the error message will give a list of
      valid values e.g.

        $ perf record -e intel_pt/mtc_period=15/u uname
        Invalid mtc_period for intel_pt. Valid values are: 0,3,6,9

      perf tools: Add new Intel PT packet definitions

      New features have been added to Intel PT which include a number of new
      packet definitions.

      This patch adds packet definitions for new packets: TMA, MTC, CYC, VMCS,
      TRACESTOP and MNT.  Also another bit in PIP is defined.

      This patch only adds support for the definitions. Later patches add
      support for decoding TMA, MTC, CYC and TRACESTOP which is where those
      packets are explained.

      VMCS and the newly defined bit in PIP are used with virtualization which
      is not supported yet.  MNT is a maintenance packet which the decoder
      should ignore.

      perf tools: Add Intel PT support for PSB periods

      The PSB packet is a synchronization packet that provides a starting
      point for decoding or recovery from errors.

      This patch adds support for a new Intel PT feature that allows the
      frequency of PSB packets to be specified.

      Support for this feature is indicated by
      /sys/bus/event_source/devices/intel_pt/caps/psb_cyc which contains "1"
      if the feature is supported and "0" otherwise.

      The PSB period can be specified as a PMU config term e.g. perf record -e
      intel_pt/psb_period=2/u sleep 1

      The default value is 3 or the nearest lower value that is supported.  0
      is always supported.

      Valid values are given by:

      /sys/bus/event_source/devices/intel_pt/caps/psb_periods

      which contains a hexadecimal value, the bits of which represent valid
      values e.g. bit 2 set means value 2 is valid.

      The value is converted to the approximate number of trace bytes between
      PSB packets as:

        2 ^ (value + 11)

      e.g. value 3 means 16KiB bytes between PSBs

      If an invalid value is entered, the error message will give a list of
      valid values e.g.

        $ perf record -e intel_pt/psb_period=15/u uname
        Invalid psb_period for intel_pt. Valid values are: 0-5

      tools/perf/Documentation/intel-pt.txt is updated in a later patch as
      there are a number of new features being added.

      lib: scatterlist: add sg splitting function

      Sometimes a scatter-gather has to be split into several chunks, or sub
      scatter lists. This happens for example if a scatter list will be
      handled by multiple DMA channels, each one filling a part of it.

      A concrete example comes with the media V4L2 API, where the scatter list
      is allocated from userspace to hold an image, regardless of the
      knowledge of how many DMAs will fill it :
       - in a simple RGB565 case, one DMA will pump data from the camera ISP
         to memory
       - in the trickier YUV422 case, 3 DMAs will pump data from the camera
         ISP pipes, one for pipe Y, one for pipe U and one for pipe V

      For these cases, it is necessary to split the original scatter list into
      multiple scatter lists, which is the purpose of this patch.

      The guarantees that are required for this patch are :
       - the intersection of spans of any couple of resulting scatter lists is
         empty.
       - the union of spans of all resulting scatter lists is a subrange of
         the span of the original scatter list.
       - streaming DMA API operations (mapping, unmapping) should not happen
         both on both the resulting and the original scatter list. It's either
         the first or the later ones.
       - the caller is reponsible to call kfree() on the resulting
         scatterlists.

      PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI

      On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at
      function 1 doesn't work if it is powered on before the SATA controller at
      function 0.  The result is that PATA doesn't work after resume, and we
      print messages like this:

        pata_jmicron 0000:02:00.1: Refused to change power state, currently in 
D3
        irq 17: nobody cared (try booting with the "irqpoll" option)

      Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
      Asynchronous threads for resume_noirq").  Prior to that, we powered on
      the functions in order, so this problem shouldn't happen.

      e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
      solved the problem for JMicron 361 and 363 devices.  With async suspend
      disabled, we always power on function 0 before function 1.

      Barto then reported the same problem with a JMicron 368 (see comment #57 
in
      the bugzilla).

      Rather than extending the blacklist piecemeal, disable async suspend for
      all JMicron multi-function SATA/PATA/AHCI devices.

      This quirk could stay in the ahci and pata_jmicron drivers, but it's 
likely
      the problem will occur even if pata_jmicron isn't loaded until after the
      suspend/resume.  Making it a PCI quirk ensures that we'll preserve the
      power-on order even if the drivers aren't loaded.

      irqchip/imx-gpcv2: IMX GPCv2 driver for wakeup sources

      IMX7D contains a new version of GPC IP block (GPCv2). It has two major
      functions: power management and wakeup source management.

      When the system is in WFI (wait for interrupt) mode, the GPC block
      will be the first block on the platform to be activated and signaled.

      In normal wait mode during cpu idle, the system can be woken up by any
      enabled interrupts. In standby or suspend mode, the system can only be
      wokem up by the pre-defined wakeup sources.

      The Maxim MAX77686 PMIC is a multi-function device with regulators,
      clocks and a RTC. The DT bindings for the clocks are in a separate
      file but the bindings for the regulators are inside the mfd part.

      To make it consistent with the clocks portion of the binding and
      because is more natural to look for regulator bindings under the
      bindings/regulator sub-directory, split the regulator portion of
      the DT binding and add it as a separate file.

      mfd: Add MFD_CROS_EC dependencies

      The MFD_CROS_EC symbol select CHROME_PLATFORMS and CROS_EC_PROTO but
      that caused a Kconfig unmet direct dependencies warning since these
      symbols could only be selected for X86 || ARM.

      The fix it, the CHROME_PLATFORMS dependencies were relexed on commit
      d12bbcd3ea44 ("platform/chrome: Don't make CHROME_PLATFORMS depends
      on X86 || ARM") but that was found to be wrong and the correct fix
      is to add the needed dependencies to the MFD_CROS_EC config symbol.

      There are only x86 and ARM based Chromebooks so to avoid showing up
      the config option on unsupported platforms, make the symbol depend on
      these architectures. Also add a || COMPILE_TEST so it can have build
      coverage on other platforms.

      mfd: cros_ec: Remove CROS_EC_PROTO dependency for SPI and I2C drivers

      The ChromeOS EC SPI and I2C transport drivers depends on CROS_EC_PROTO
      but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends
      on is bad practice as it may lead to circular Kconfig dependencies.

      Since these drivers already depend on MFD_CROS_EC and that config option
      already selects CROS_EC_PROTO, there is no need to make them explicitly
      depend on CROS_EC_PROTO since that dependency is already met.

      crypto: caam - fix writing to JQCR_MS when using service interface

      Most significant part of JQCR (Job Queue Control Register) contains
      bits that control endianness: ILE - Immediate Little Endian,
      DWS - Double Word Swap.
      The bits are automatically set by the Job Queue Controller HW.

      Unfortunately these bits are cleared in SW when submitting descriptors
      via the register-based service interface.
      >From LS1021A:
      JQCR_MS = 08080100 - before writing: ILE | DWS | SRC (JR0)
      JQCR_MS = 30000100 - after writing: WHL | FOUR | SRC (JR0)

      This would cause problems on little endian caam for descriptors
      containing immediata data or double-word pointers.
      Currently there is no problem since the only descriptors ran through
      this interface are the ones that (un)instantiate RNG.

      PCI: Set MPS to match upstream bridge

      Firmware typically configures the PCIe fabric with a consistent Max 
Payload
      Size setting based on the devices present at boot.  A hot-added device
      typically has the power-on default MPS setting (128 bytes), which may not
      match the fabric.

      The previous Linux default, in the absence of any "pci=pcie_bus_*" 
options,
      was PCIE_BUS_TUNE_OFF, in which we never touch MPS, even for hot-added
      devices.

      Add a new default setting, PCIE_BUS_DEFAULT, in which we make sure every
      device's MPS setting matches the upstream bridge.  This makes it more
      likely that a hot-added device will work in a system with optimized MPS
      configuration.

      Note that if we hot-add a device that only supports 128-byte MPS, it still
      likely won't work because we don't reconfigure the rest of the fabric.
      Booting with "pci=pcie_bus_peer2peer" is a workaround for this because it
      sets MPS to 128 for everything.

      Since the platform device that is matched with the I2C bus driver
      is registered by the ChromeOS EC mfd driver, I2C_CROS_EC_TUNNEL
      really depends on MFD_CROS_EC. And because this config option
      selects CROS_EC_PROTO, that dependency is met as well. So make the
      driver to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

      arm64: set MAX_MEMBLOCK_ADDR according to linear region size

      The linear region size of a 39-bit VA kernel is only 256 GB, which
      may be insufficient to cover all of system RAM, even on platforms
      that have much less than 256 GB of memory but which is laid out
      very sparsely.

      So make sure we clip the memory we will not be able to map before
      installing it into the memblock memory table, by setting
      MAX_MEMBLOCK_ADDR accordingly.

      of/fdt: make memblock maximum physical address arch configurable

      When parsing the memory nodes to populate the memblock memory
      table, we check against high and low limits and clip any memory
      that exceeds either one of them.

      However, for arm64, the high limit of (phys_addr_t)~0 is not very
      meaningful, since phys_addr_t is 64 bits (i.e., no limit) but there
      may be other constraints that limit the memory ranges that we can
      support.

      So rename MAX_PHYS_ADDR to MAX_MEMBLOCK_ADDR (for clarity) and only
      define it if the arch does not supply a definition of its own.

switching

      The pfc in the R8A7790 (and probably others in the R-Car gen 2 family)
      supports switching SDHI signals between 3.3V and 1.8V nominal voltage,
      and the SD driver should do that when switching to and from UHS modes.

      Add a flag for pins that have configurable I/O voltage and SoC
      operations to get and set the nominal voltage.  Implement the pinconf
      power-source parameter using these operations.

      drm/i915: Allow parsing of variable size child device entries from VBT

      VBT version 196 increased the size of common_child_dev_config. The
      parser code assumed that the size of this structure would not change.

      The modified code now copies the amount needed based on the VBT version,
      and emits a debug message if the VBT version is unknown (too new); since
      the struct config block won't shrink in newer versions it should be
      harmless to copy the maximum known size in such cases, so that's what we
      do, but emitting the warning is probably sensible anyway.

      In the longer run it might make sense to modify the parser code to use a
      version/feature mapping, rather than hardcoding things like this, but
      for now the variants are fairly manageable.

      This fixes a regression introduced in

triggered.

      This patch fixes the breakage by moving the lwtunnel state to the end of

      with __refcnt and may affect performance, thus further patches may be

      tipc: fix stale link problem during synchronization

      Recent changes to the link synchronization means that we can now just
      drop packets arriving on the synchronizing link before the synch point
      is reached. This has lead to significant simplifications to the
      implementation, but also turns out to have a flip side that we need
      to consider.

      Under unlucky circumstances, the two endpoints may end up
      repeatedly dropping each other's packets, while immediately
      asking for retransmission of the same packets, just to drop
      them once more. This pattern will eventually be broken when
      the synch point is reached on the other link, but before that,
      the endpoints may have arrived at the retransmission limit
      (stale counter) that indicates that the link should be broken.
      We see this happen at rare occasions.

      The fix for this is to not ask for retransmissions when a link is in
      state LINK_SYNCHING. The fact that the link has reached this state
      means that it has already received the first SYNCH packet, and that it
      knows the synch point. Hence, it doesn't need any more packets until the
      other link has reached the synch point, whereafter it can go ahead and
      ask for the missing packets.

      However, because of the reduced traffic on the synching link that
      follows this change, it may now take longer to discover that the
      synch point has been reached. We compensate for this by letting all
      packets, on any of the links, trig a check for synchronization
      termination. This is possible because the packets themselves don't
      contain any information that is needed for discovering this condition.

      tipc: interrupt link synchronization when a link goes down

      When we introduced the new link failover/synch mechanism
      in commit 6e498158a827fd515b514842e9a06bdf0f75ab86
      ("tipc: move link synch and failover to link aggregation level"),
      we missed the case when the non-tunnel link goes down during the link
      synchronization period. In this case the tunnel link will remain in
      state LINK_SYNCHING, something leading to unpredictable behavior when
      the failover procedure is initiated.

      In this commit, we ensure that the node and remaining link goes
      back to regular communication state (SELF_UP_PEER_UP/LINK_ESTABLISHED)
      when one of the parallel links goes down. We also ensure that we don't
      re-enter synch mode if subsequent SYNCH packets arrive on the remaining
      link.

      tipc: eliminate risk of premature link setup during failover

      When a link goes down, and there is still a working link towards its
      destination node, a failover is initiated, and the failed link is not
      allowed to re-establish until that procedure is finished. To ensure
      this, the concerned link endpoints are set to state LINK_FAILINGOVER,
      and the node endpoints to NODE_FAILINGOVER during the failover period.

      However, if the link reset is due to a disabled bearer, the corres-
      ponding link endpoint is deleted, and only the node endpoint knows
      about the ongoing failover. Now, if the disabled bearer is re-enabled
      during the failover period, the discovery mechanism may create a new
      link endpoint that is ready to be established, despite that this is not
      permitted. This situation may cause both the ongoing failover and any
      subsequent link synchronization to fail.

      In this commit, we ensure that a newly created link goes directly to
      state LINK_FAILINGOVER if the corresponding node state is
      NODE_FAILINGOVER. This eliminates the problem described above.

      Furthermore, we tighten the criteria for which packets are allowed
      to end a failover state in the function tipc_node_check_state().
      By checking that the receiving link is up and running, instead of just
      checking that it is not in failover mode, we eliminate the risk that
      protocol packets from the re-created link may cause the failover to
      be prematurely terminated.

      ====================
      *** nps_enet fixups ***

      Change v2
      TX done is handled back with NAPI poll.

      Change v1
      This patch set is a bunch of fixes to make nps_enet work correctly with
      all platforms, i.e. real device, emulation system, and simulation system.
      The main trigger for this patch set was that in our emulation system
      the TX end interrupt is "edge-sensitive" and therefore we cannot use the
      cause register since it is not sticky.
      Also:
      TX is handled during HW interrupt context and not NAPI job.
      race with TX done was fixed.
      added acknowledge for TX when device is "level sensitive".
      enable drop of control frames which is not needed for regular usage.

      So most of this patch set is about TX handling, which is now more 
complete.

      In the meantime, change the 802.1Q mode of every ports to Fallback,
      which filtering is more permissive, and doesn't add this restriction to

      drivers/dma: make mv_xor.c driver explicitly non-modular

      The Kconfig for this driver is currently:

      config MV_XOR
              bool "Marvell XOR engine support"

      ...meaning that it currently is not being built as a module by anyone.
      Lets remove the modular code that is essentially orphaned, so that
      when reading the driver there is no doubt it is builtin-only.

      Since module_init translates to device_initcall in the non-modular
      case, the init ordering remains unchanged with this commit.

      We leave some tags like MODULE_AUTHOR for documentation purposes.
      Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

      dmaengine: Add support for the Analog Devices AXI-DMAC DMA controller

      Add support for the Analog Devices AXI-DMAC DMA controller. This 
controller
      is a soft peripheral that can be instantiated in a FPGA and is often used
      in Analog Devices' reference designs for FPGA platforms.

      The peripheral has various configuration options that can be selected at
      synthesis time and influence the supported features of the instantiated
      peripheral, those options are represented as device-tree properties to
      allow the driver to behave accordingly.

      The peripheral has a zero latency architecture, which means it is possible
      to switch from one to the next descriptor without any delay. This is
      archived by having a internal queue which can hold multiple descriptors.
      The driver supports this, which means it will submit new descriptors
      directly to the hardware until the queue is full and not wait for a
      descriptor to complete before the next one is submitted. Interrupts are
      used for the descriptor queue flow control.

      Currently the driver supports SG, cyclic and interleaved slave DMA.

      argument is 32 bits. This makes it unnecessarily awkward to
      write code that puts an unsigned long into an MSR.

      To make this work, syscall_init needs tweaking to stop passing
      a function pointer to wrmsrl.

      9p: ensure err is initialized to 0 in p9_client_read/write

      Some use of those functions were providing unitialized values to those

          #include <sys/stat.h>
          #include <fcntl.h>

          int main(int argc, const char **argv)
          {
              assert(argc == 2);
              char buffer[256];
              int fd = open(argv[1], O_RDONLY|O_NOCTTY);
              assert(fd >= 0);
              assert(read(fd, buffer, 0) == 0);

      x86/apic: Fix fallout from x2apic cleanup

      In the recent x2apic cleanup I got two things really wrong:
      1) The safety check in __disable_x2apic which allows the function to
         be called unconditionally is backwards. The check is there to
         prevent access to the apic MSR in case that the machine has no
         apic. Though right now it returns if the machine has an apic and
         therefor the disabling of x2apic is never invoked.

      2) x2apic_disable() sets x2apic_mode to 0 after registering the local
         apic. That's wrong, because register_lapic_address() checks x2apic
         mode and therefor takes the wrong code path.

      This results in boot failures on machines with x2apic preenabled by
      BIOS and can also lead to an fatal MSR access on machines without
      apic.

      The solutions are simple:
      1) Correct the sanity check for apic availability
      2) Clear x2apic_mode _before_ calling register_lapic_address()

      x86/kasan, mm: Introduce generic kasan_populate_zero_shadow()

      Introduce generic kasan_populate_zero_shadow(shadow_start,
      shadow_end). This function maps kasan_zero_page to the
      [shadow_start, shadow_end] addresses.

      This replaces x86_64 specific populate_zero_shadow() and will
      be used for ARM64 in follow on patches.

      The main changes from original version are:

       * Use p?d_populate*() instead of set_p?d()
       * Use memblock allocator directly instead of vmemmap_alloc_block()
       * __pa() instead of __pa_nodebug(). __pa() causes troubles
         iff we use it before kasan_early_init(). kasan_populate_zero_shadow()
         will be used later, so we ok with __pa() here.

      x86/asm/delay: Introduce an MWAITX-based delay with a configurable timer

      MWAITX can enable a timer and a corresponding timer value
      specified in SW P0 clocks. The SW P0 frequency is the same as
      TSC. The timer provides an upper bound on how long the
      instruction waits before exiting.

      This way, a delay function in the kernel can leverage that
      MWAITX timer of MWAITX.

      When a CPU core executes MWAITX, it will be quiesced in a
      waiting phase, diminishing its power consumption. This way, we
      can save power in comparison to our default TSC-based delays.

      A simple test shows that:

        $ cat /sys/bus/pci/devices/0000\:00\:18.4/hwmon/hwmon0/power1_acc
        $ sleep 10000s
        $ cat /sys/bus/pci/devices/0000\:00\:18.4/hwmon/hwmon0/power1_acc

      Results:

        * TSC-based default delay:      485115 uWatts average power
        * MWAITX-based delay:           252738 uWatts average power

      Thus, that's about 240 milliWatts less power consumption. The
      test method relies on the support of AMD CPU accumulated power
      algorithm in fam15h_power for which patches are forthcoming.

      x86/asm: Add MONITORX/MWAITX instruction support

      AMD Carrizo processors (Family 15h, Models 60h-6fh) added a new
      feature called MWAITX (MWAIT with extensions) as an extension to
      MONITOR/MWAIT.

      This new instruction controls a configurable timer which causes
      the core to exit wait state on timer expiration, in addition to
      "normal" MWAIT condition of reading from a monitored VA.

      Compared to MONITOR/MWAIT, there are minor differences in opcode
      and input parameters:

      MWAITX ECX[1]: enable timer if set
      MWAITX EBX[31:0]: max wait time expressed in SW P0 clocks ==
      TSC. The software P0 frequency is the same as the TSC frequency.

                      MWAIT                           MWAITX
      opcode          0f 01 c9           |            0f 01 fb
      ECX[0]                  value of RFLAGS.IF seen by instruction
      ECX[1]          unused/#GP if set  |            enable timer if set
      ECX[31:2]                     unused/#GP if set
      EAX                           unused (reserve for hint)
      EBX[31:0]       unused             |            max wait time (SW P0 == 
TSC)

                      MONITOR                         MONITORX
      opcode          0f 01 c8           |            0f 01 fa
      EAX                     (logical) address to monitor
      ECX                     #GP if not zero

      Max timeout = EBX/(TSC frequency)

      [media] videobuf2-core: Add it to device-drivers DocBook

      Most of the stuff at videobuf2-core are ok for adding it to
      DocBook.

      Two notes here:
      1) As videobuf2-core will be soon be changed, better to
         not spend too much efforts right now, as things will
         change soon;

      2) struct vb2_queue has a number of private elements that are
         documented. As Kernel nano documentation format handles
         "private:" arguments, we need to put them on a separate
         comment block or to remove. Keeping the comments is
         obviously better ;)

      When I merged the OPAL support for the powernv LEDS driver I missed a
      hunk.

      This is slightly modified from the original patch, as the original added
      code to opal-api.h which is not in the skiboot version, which is
      discouraged.

      Instead those values are moved into the driver, which is the only place
      they are used.

      KVM: PPC: Book3S: correct width in XER handling

      In 64 bit kernels, the Fixed Point Exception Register (XER) is a 64
      bit field (e.g. in kvm_regs and kvm_vcpu_arch) and in most places it is
      accessed as such.

      This patch corrects places where it is accessed as a 32 bit field by a
      64 bit kernel.  In some cases this is via a 32 bit load or store
      instruction which, depending on endianness, will cause either the
      lower or upper 32 bits to be missed.  In another case it is cast as a
      u32, causing the upper 32 bits to be cleared.

      This patch corrects those places by extending the access methods to
      64 bits.

      When clearing the reference or change bit in the guest view of the HPTE,

      to the rmap entry for the underlying host page so that kvm_age_hva_hv(),
      kvm_test_age_hva_hv() and kvmppc_hv_get_dirty_log() know that the page
      has been referenced and/or changed.

      KVM: PPC: Book3S HV: Fix bug in dirty page tracking

      This fixes a bug in the tracking of pages that get modified by the
      guest.  If the guest creates a large-page HPTE, writes to memory
      somewhere within the large page, and then removes the HPTE, we only
      record the modified state for the first normal page within the large
      page, when in fact the guest might have modified some other normal
      page within the large page.

      To fix this we use some unused bits in the rmap entry to record the
      order (log base 2) of the size of the page that was modified, when
      removing an HPTE.  Then in kvm_test_clear_dirty_npages() we use that
      order to return the correct number of modified pages.

      The same thing could in principle happen when removing a HPTE at the
      host's request, i.e. when paging out a page, except that we never
      page out large pages, and the guest can only create large-page HPTEs
      if the guest RAM is backed by large pages.  However, we also fix
      this case for the sake of future-proofing.

      The reference bit is also subject to the same loss of information.  We
      don't make the same fix here for the reference bit because there isn't
      an interface for userspace to find out which pages the guest has
      referenced, whereas there is one for userspace to find out which pages
      the guest has modified.  Because of this loss of information, the
      kvm_age_hva_hv() and kvm_test_age_hva_hv() functions might incorrectly
      say that a page has not been referenced when it has, but that doesn't
      matter greatly because we never page or swap out large pages.

      KVM: PPC: Book3S HV: Fix race in reading change bit when removing HPTE

      The reference (R) and change (C) bits in a HPT entry can be set by
      hardware at any time up until the HPTE is invalidated and the TLB
      invalidation sequence has completed.  This means that when removing
      a HPTE, we need to read the HPTE after the invalidation sequence has
      completed in order to obtain reliable values of R and C.  The code
      in kvmppc_do_h_remove() used to do this.  However, commit 6f22bd3265fb
      ("KVM: PPC: Book3S HV: Make HTAB code LE host aware") removed the
      read after invalidation as a side effect of other changes.  This
      restores the read of the HPTE after invalidation.

      The user-visible effect of this bug would be that when migrating a
      guest, there is a small probability that a page modified by the guest
      and then unmapped by the guest might not get re-transmitted and thus
      the destination might end up with a stale copy of the page.

      KVM: PPC: Book3S HV: Implement dynamic micro-threading on POWER8

      This builds on the ability to run more than one vcore on a physical
      core by using the micro-threading (split-core) modes of the POWER8
      chip.  Previously, only vcores from the same VM could be run together,
      and (on POWER8) only if they had just one thread per core.  With the
      ability to split the core on guest entry and unsplit it on guest exit,
      we can run up to 8 vcpu threads from up to 4 different VMs, and we can
      run multiple vcores with 2 or 4 vcpus per vcore.

      Dynamic micro-threading is only available if the static configuration
      of the cores is whole-core mode (unsplit), and only on POWER8.

      To manage this, we introduce a new kvm_split_mode struct which is
      shared across all of the subcores in the core, with a pointer in the
      paca on each thread.  In addition we extend the core_info struct to
      have information on each subcore.  When deciding whether to add a
      vcore to the set already on the core, we now have two possibilities:
      (a) piggyback the vcore onto an existing subcore, or (b) start a new
      subcore.

      Currently, when any vcpu needs to exit the guest and switch to host
      virtual mode, we interrupt all the threads in all subcores and switch
      the core back to whole-core mode.  It may be possible in future to
      allow some of the subcores to keep executing in the guest while
      subcore 0 switches to the host, but that is not implemented in this
      patch.

      This adds a module parameter called dynamic_mt_modes which controls
      which micro-threading (split-core) modes the code will consider, as a
      bitmap.  In other words, if it is 0, no micro-threading mode is
      considered; if it is 2, only 2-way micro-threading is considered; if
      it is 4, only 4-way, and if it is 6, both 2-way and 4-way
      micro-threading mode will be considered.  The default is 6.

      With this, we now have secondary threads which are the primary thread
      for their subcore and therefore need to do the MMU switch.  These
      threads will need to be started even if they have no vcpu to run, so
      we use the vcore pointer in the PACA rather than the vcpu pointer to
      trigger them.

      It is now possible for thread 0 to find that an exit has been
      requested before it gets to switch the subcore state to the guest.  In
      that case we haven't added the guest's timebase offset to the
      timebase, so we need to be careful not to subtract the offset in the
      guest exit path.  In fact we just skip the whole path that switches
      back to host context, since we haven't switched to the guest context.

      KVM: PPC: Book3S HV: Make use of unused threads when running guests

      When running a virtual core of a guest that is configured with fewer
      threads per core than the physical cores have, the extra physical
      threads are currently unused.  This makes it possible to use them to
      run one or more other virtual cores from the same guest when certain
      conditions are met.  This applies on POWER7, and on POWER8 to guests
      with one thread per virtual core.  (It doesn't apply to POWER8 guests
      with multiple threads per vcore because they require a 1-1 virtual to
      physical thread mapping in order to be able to use msgsndp and the
      TIR.)

      The idea is that we maintain a list of preempted vcores for each
      physical cpu (i.e. each core, since the host runs single-threaded).
      Then, when a vcore is about to run, it checks to see if there are
      any vcores on the list for its physical cpu that could be
      piggybacked onto this vcore's execution.  If so, those additional
      vcores are put into state VCORE_PIGGYBACK and their runnable VCPU
      threads are started as well as the original vcore, which is called
      the master vcore.

      After the vcores have exited the guest, the extra ones are put back
      onto the preempted list if any of their VCPUs are still runnable and
      not idle.

      This means that vcpu->arch.ptid is no longer necessarily the same as
      the physical thread that the vcpu runs on.  In order to make it easier
      for code that wants to send an IPI to know which CPU to target, we
      now store that in a new field in struct vcpu_arch, called thread_cpu.

      x86/traps: Weaken context tracking entry assertions

      We were asserting that we were all the way in CONTEXT_KERNEL
      when exception handlers were called.  While having this be true
      is, I think, a nice goal (or maybe a variant in which we assert
      that we're in CONTEXT_KERNEL or some new IRQ context), we're not
      quite there.

      In particular, if an IRQ interrupts the SYSCALL prologue and the
      IRQ handler in turn causes an exception, the exception entry
      will be called in RCU IRQ mode but with CONTEXT_USER.

      This is okay (nothing goes wrong), but until we fix up the
      SYSCALL prologue, we need to avoid warning.

      hrtimer: Handle failure of tick_init_highres() gracefully

      Commit 75e3b37d0598 ("hrtimer: Drop return code of 
hrtimer_switch_to_hres()")
      drops the return code of hrtimer_switch_to_hres(). While doing so, it also
      drops the return statement itself on failure. This may cause a system 
hang.
      Seen when running arm:multi_v7_defconfig in qemu with devicetree file
      vexpress-v2p-ca9.

      f2fs: lookup neighbor extent nodes for merging later

      In __lookup_extent_tree_ret we will not try to find neighbor nodes if
      we find the target node, in this condition, we will lost the chance to
      merge the new mapping with exist extent node later.

      So our extent cache of inode will be fragmented after overwrite exist
      file, we can see the number of extent node increases intensively in
      following test case:

      dd if=/dev/zero of=/mnt/f2fs/4m bs=4K count=1024

      Extent Cache:
        - Hit Count: L1-1:0 L1-2:0 L2:0
        - Hit Ratio: 0% (0 / 3072)
        - Inner Struct Count: tree: 1, node: 1

      dd if=/dev/zero of=/mnt/f2fs/4m bs=4K count=1024 conv=notrunc

      Extent Cache:
        - Hit Count: L1-1:2048 L1-2:0 L2:0
        - Hit Ratio: 33% (2048 / 6144)
        - Inner Struct Count: tree: 1, node: 961

      This patch fixes to lookup neighbors of target node for further

      After commit 0f825ee6e873 ("f2fs: add new interfaces for extent tree"),
      f2fs_init_extent_tree becomes the only caller of __insert_extent_tree, and
      in f2fs_init_extent_tree, we will only insert extent node in an empty 
tree,
      so __try_{back,front}_merge in __insert_extent_tree will never be called.

      This patch alters to replace total hit stat with rbtree hit stat,
      and then adjust showing of extent cache stat:

      Hit Count:

      L1-2: for last cached node hit count;
      L2: for extent node hit after lookuping in rbtree.

      Hit Ratio:
      ratio (hit count / total lookup count)

      Inner Struct Count:
      tree count, node count.

      f2fs: fix incorrect mapping for bmap

      The test step is like below:
      1. touch file
      2. truncate -s $((1024*1024)) file
      3. fallocate -o 0 -l $((1024*1024)) file
      4. fibmap.f2fs file

      Our result of fibmap.f2fs showed below is not correct:

      file_pos   start_blk     end_blk        blks
             0    -937166132    -937166132           1
          4096    -937166132    -937166132           1
          8192    -937166132    -937166132           1
         12288    -937166132    -937166132           1
         16384    -937166132    -937166132           1
         20480    -937166132    -937166132           1
      ...
       1040384    -937166132    -937166132           1
       1044480    -937166132    -937166132           1

      This is because f2fs_map_blocks will return with no error when meeting
      a hole or preallocated block, the caller __get_data_block will map the
      uninitialized variable value to bh->b_blocknr.

      Unfortunately generic_block_bmap will neither check the return value of
      get_data() nor check mapping info of buffer_head, result in returning
      the random block address.

      After fixing the issue, our result shows correctly:

      file_pos   start_blk     end_blk        blks
             0           0           0         256

      In f2fs_lookup_extent_tree, et->cached_en was read and updated with only
      read lock held,
      it could cause __lookup_extent_tree within return entirely wrong
      extent_node, if other
      thread update et->cached_en just before __lookup_extent_tree return.

      However, there are two things about this patch that need to be noticed:
      1. It does no good to arrange the order of concurrent read/write, the 
result
      would still
      be random in such case.
      2. It's built on this assumption: the mix up of reads and writes on a 
single
      pointer would
      not make the pointer partially wrong at any time. Please let me know if 
I'm
      wrong, thx.

      mtd: dataflash: Export OF module alias information

      The SPI core currently reports the MODALIAS uevent as "spi:<modalias>"
      even for SPI devices that were registered by OF.

      That means the OF module alias exported by MODULE_OF_TABLE(of,...) is
      currently not used and user-space has no way to autoload this module.

      But it is still a good practice to add the OF module alias information
      into the kernel module even when it currently is unused so once the SPI
      core is changed to report a correct OF modalias uevent, module
      autoloading will be working for this driver.

      DRM - radeon: Don't link train DisplayPort on HPD until we get the dpcd

      Most of the time this isn't an issue since hotplugging an adaptor will
      trigger a crtc mode change which in turn, causes the driver to probe
      every DisplayPort for a dpcd. However, in cases where hotplugging
      doesn't cause a mode change (specifically when one unplugs a monitor
      from a DisplayPort connector, then plugs that same monitor back in
      seconds later on the same port without any other monitors connected), we
      never probe for the dpcd before starting the initial link training. What
      happens from there looks like this:

        - GPU has only one monitor connected. It's connected via
          DisplayPort, and does not go through an adaptor of any sort.

        - User unplugs DisplayPort connector from GPU.

        - Change in HPD is detected by the driver, we probe every
          DisplayPort for a possible connection.

        - Probe the port the user originally had the monitor connected
          on for it's dpcd. This fails, and we clear the first (and only
          the first) byte of the dpcd to indicate we no longer have a
          dpcd for this port.

        - User plugs the previously disconnected monitor back into the
          same DisplayPort.

        - radeon_connector_hotplug() is called before everyone else,
          and tries to handle the link training. Since only the first
          byte of the dpcd is zeroed, the driver is able to complete
          link training but does so against the wrong dpcd, causing it
          to initialize the link with the wrong settings.

        - Display stays blank (usually), dpcd is probed after the
          initial link training, and the driver prints no obvious
          messages to the log.

      In theory, since only one byte of the dpcd is chopped off (specifically,
      the byte that contains the revision information for DisplayPort), it's
      not entirely impossible that this bug may not show on certain monitors.
      For instance, the only reason this bug was visible on my ASUS PB238
      monitor was due to the fact that this monitor using the enhanced framing
      symbol sequence, the flag for which is ignored if the radeon driver
      thinks that the DisplayPort version is below 1.1.

      ALSA: ac97: Switch to dev_pm_ops

      Convert the ac97_bus from legacy suspend/resume callbacks to dev_pm_ops.

      Since there isn't anything special to do at the bus level the bus driver
      does not have to implement any callbacks. The device driver core will
      automatically pick up and execute the device's PM ops.

      As there is only a single AC'97 driver implementing suspend and resume,
      update both the core and driver at the same time to avoid unnecessary code
      churn.

      While we are at it also drop the ifdefs around the suspend/resume 
functions

      spi: dw: Allow interface drivers to limit data I/O to word sizes

      The commit dd11444327ce ("spi: dw-spi: Convert 16bit accesses to 32bit
      accesses") changed all 16bit accesses in the DW_apb_ssi driver to 32bit.
      This, unfortunately, breaks data register access on picoXcell, where the
      DW IP needs data register accesses to be word accesses (all other
      accesses appear to be OK).

      This change introduces a new master variable to allow interface drivers
      to specify that 16bit data transfer I/O is required.  This change also
      introduces the ability to set this variable via device tree bindings in
      the MMIO interface driver.  Both the core and the MMIO interface driver
      default to the current 32bit behaviour.

      Before this change, on a picoXcell pc3x3:
       spi_master spi32766: interrupt_transfer: fifo overrun/underrun
       m25p80 spi32766.0: error -5 reading 9f
       m25p80: probe of spi32766.0 failed with error -5

      After this change:
       m25p80 spi32766.0: m25p40 (512 Kbytes)

        tegra-ahb 6000c004.ahb: incorrect AHB base address in DT data - 
enabling workaround

      To correct old DTBs, commit ce7a10b0ff3d ("ARM: 8334/1: amba: tegra-ahb:
      detect and correct bogus base address") checks for the low bit of the
      base address and removes theses 0x04 bytes at runtime.

      This patch fixes the original DTS, so upstream version doesn't need the
      workaround of the base address.

      As both addresses are valid, this patch doesn't break compatibility.

      Tested on tegra20-paz00 (aka ac100).

      use_single_rw currently reflects the capabilities of the connected
      device. The capabilities of the bus are currently missing for this
      variable.

      As there are read only and write only buses we need seperate values for
      use_single_rw to also reflect tha capabilities of the bus.

      This patch splits use_single_rw into use_single_read and
      use_single_write. The initialization is changed to check the
      configuration for use_single_rw and to check the capabilities of the
      used bus.

      ipvs: call rtnl_lock early

      When the sync damon is started we need to hold rtnl
      lock while calling ip_mc_join_group. Currently, we have
      a wrong locking order because the correct one is
      rtnl_lock->__ip_vs_mutex. It is implied from the usage
      of __ip_vs_mutex in ip_vs_dst_event() which is called
      under rtnl lock during NETDEV_* notifications.

      Fix the problem by calling rtnl_lock early only for the
      start_sync_thread call. As a bonus this fixes the usage
      __dev_get_by_name which was not called under rtnl lock.

      This patch actually extends and depends on commit 54ff9ef36bdf

      perf probe: Try to use symbol table if searching debug info failed

      A problem can occur in a statically linked perf when vmlinux can be found:

       # perf probe --add sys_epoll_pwait
       probe-definition(0): sys_epoll_pwait
       symbol:sys_epoll_pwait file:(null) line:0 offset:0 return:0 lazy:(null)

       An error occurred in debuginfo analysis (-2).
         Error: Failed to add events. Reason: No such file or directory (Code: 
-2)

      The reason is caused by libdw that, if libdw is statically linked, it
      can't load libebl_{arch}.so reliable.

      In this case it is still possible to get the address from
      /proc/kalksyms.  However, perf tries that only when libdw returns
      -EBADF.

      This patch gives it another chance to utilize symbol table, even if
      libdw returns an error code other than -EBADF.

      After applying this patch:

       # perf probe -nv --add sys_epoll_pwait
       probe-definition(0): sys_epoll_pwait
       symbol:sys_epoll_pwait file:(null) line:0 offset:0 return:0 lazy:(null)

       Writing event: p:probe/sys_epoll_pwait _text+2276672
         probe:sys_epoll_pwait (on sys_epoll_pwait)

       You can now use it in all perf tools, such as:

        perf record -e probe:sys_epoll_pwait -aR sleep 1

      Although libdw returns an error (Failed to get call frame), perf tries
      symbol table and finally gets correct address.

      perf tools: Initialize reference counts in map__clone()

      Map clone was written before we introduced reference counts for
      maps and dsos, so all that was needed was just a copy and then we
      would insert it into the new map_groups instance.

      Fix it by, after copying, initializing the map->refcnt, grabbing
      a struct dso refcount and resetting pointers that may be used
      to determine if a map, when deleted, is in a rb_tree.

      one.

      perf tools: Add example call-graph script

      Add a script to produce a call-graph from data exported to a postgresql
      database and derived from a processor trace event like intel_pt or 
intel_bts.

      Refer to comments in the scripts call-graph-from-postgresql.py and
      export-to-postgresql.py for more details on how to set up the environment,
      install the required packages, etc.

      Committer note:

      From the scripts, for convenience while reading 'git log':

        An example of using this script with Intel PT:

        $ perf record -e intel_pt//u ls
        $ perf script -s

      bq2415x_charger: Allow to load and use driver even if notify device is 
not registered yet

      Driver bq2415x_charger works also without notify power supply device for
      charger detection. But when charger detection is specified in DT, then
      bq2415x_charger refused to loaded with -EPROBE_DEFER.

      This patch rewrites code so that notify device for charger detection is
      checked when power supply event is received and not when registering power
      supply device. So this patch allows to use bq2415x_charger driver also 
when
      kernel is compiled without driver for notify power supply device.

      Now after this patch scheduled workqueue is called after 
INIT_DELAYED_WORK,
      so it also fix problem when scheduled workqueue was called before init.

      perf tools: Add Intel BTS support

      Intel BTS support fits within the new auxtrace infrastructure.  Recording 
is
      supporting by identifying the Intel BTS PMU, parsing options and setting 
up
      events.

      Decoding is supported by queuing up trace data by thread and then decoding
      synchronously delivering synthesized event samples into the session 
processing
      for tools to consume.

      crypto: skcipher - Add top-level skcipher interface

      This patch introduces the crypto skcipher interface which aims
      to replace both blkcipher and ablkcipher.

      It's very similar to the existing ablkcipher interface.  The
      main difference is the removal of the givcrypt interface.  In
      order to make the transition easier for blkcipher users, there
      is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place
      a request on the stack for synchronous transforms.

      arm64: entry: always restore x0 from the stack on syscall return

      We have a micro-optimisation on the fast syscall return path where we
      take care to keep x0 live with the return value from the syscall so that
      we can avoid restoring it from the stack. The benefit of doing this is
      fairly suspect, since we will be restoring x1 from the stack anyway
      (which lives adjacent in the pt_regs structure) and the only additional
      cost is saving x0 back to pt_regs after the syscall handler, which could
      be seen as a poor man's prefetch.

      More importantly, this causes issues with the context tracking code.

      The ct_user_enter macro ends up branching into C code, which is free to
      use x0 as a scratch register and consequently leads to us returning junk
      back to userspace as the syscall return value. Rather than special case
      the context-tracking code, this patch removes the questionable
      optimisation entirely.

      The second warning was a result of the first warning not stopping
      processing after it detected the issue.

      That is, code that found the issue reported the first problem, but
      because it did not exit out of the functions smoothly, it caused the
      other warning to appear and not only that, it later caused the SIGSEGV.

      perf tools: Fix Intel PT timestamp handling

      Events that don't sample the timestamp have a timestamp value of -1.

      Intel PT processing wasn't taking that into account.

      This is particularly noticeable with Intel BTS because timestamps are
      not requested by default.

      Then, if the conversion of -1 to TSC results in a small number, the
      processing is unaffected.

      However if the conversion results in a big number, then the data is
      processed prematurely before relevant sideband data like mmap events,
      which in turn results in samples with unknown dsos.

      Commiter note:

      Since BTS wasn't upstream, I split the patch to fold the BTS part with
      the patch introducing it, to avoid having this bug in the commit
      history. PT was already upstream, so this patch contains that part.

      perf tools: /proc/kcore requires CAP_SYS_RAWIO message too noisy

      The "/proc/kcore requires CAP_SYS_RAWIO" message comes up all the time
      for 'perf script' if vmlinux is not found and the user isn't root, even
      when the kernel is not being traced and even though the message is only

      Change it to pr_debug and instead put a note in the message displayed if
      annotation is not possible.

      Also, the file being accessed might not be /proc/kcore.  Tools can be

      perf script: Fix segfault using --show-mmap-events

      Patch "perf script: Don't assume evsel position of tracking events"
      changed 'perf script' to use 'perf_evlist__id2evsel()'. That results
      in a segfault if there is more than 1 event and there are
      synthesized mmap events e.g.

        $ perf record -e cycles,instructions -p$$ sleep 1
        $ perf script --show-mmap-events
        Segmentation fault (core dumped)

      That happens because these synthesized events have an 'id' of zero
      which does not match any 'evsel'.

      Currently, these synthesized events use the sample type of the first
      evsel.

      Change 'perf_evlist__id2evsel()' to reflect that which also makes
      it consistent with 'perf_evlist__event2evsel()'.

      ALSA: hda - Refresh widgets sysfs at probing Haswell+ HDMI codecs

      Intel Haswell (and later) codec refreshes the widgets tree to expose
      the whole widget nodes at probing.  However, this refresh was missing
      for sysfs tree.

      This patch adds the missing piece, as we have now a proper API.

      vfs: Test for and handle paths that are unreachable from their mnt_root

      In rare cases a directory can be renamed out from under a bind mount.
      In those cases without special handling it becomes possible to walk up
      the directory tree to the root dentry of the filesystem and down
      from the root dentry to every other file or directory on the filesystem.

      Like division by zero .. from an unconnected path can not be given
      a useful semantic as there is no predicting at which path component
      the code will realize it is unconnected.  We certainly can not match
      the current behavior as the current behavior is a security hole.

      Therefore when encounting .. when following an unconnected path
      return -ENOENT.

      - Add a function path_connected to verify path->dentry is reachable
        from path->mnt.mnt_root.  AKA to validate that rename did not do
        something nasty to the bind mount.

        To avoid races path_connected must be called after following a path
        component to it's next path component.

      The Hyper-V top-level functional specification states, that
      "algorithms should be resilient to sudden jumps forward or
      backward in the TSC value", this means that we should consider
      TSC as unstable. In some cases tsc tests are able to detect the
      instability, it was detected in 543 out of 646 boots in my
      testing:

       Measured 6277 cycles TSC warp between CPUs, turning off TSC clock.
       tsc: Marking TSC unstable due to check_tsc_sync_source failed

      This is, however, just a heuristic. On Hyper-V platform there
      are two good clocksources: MSR-based hyperv_clocksource and
      recently introduced TSC page.

      dcache: Reduce the scope of i_lock in d_splice_alias

      i_lock is only needed until __d_find_any_alias calls dget on the alias
      dentry.  After that the reference to new ensures that dentry_kill and
      d_delete will not remove the inode from the dentry, and remove the
      dentry from the inode->d_entry list.

      The inode i_lock came to be held over the the __d_move calls in
      d_splice_alias through a series of introduction of locks with
      increasing smaller scope.  First it was the dcache_lock, then
      it was the dcache_inode_lock, and finally inode->i_lock.

      Furthermore inode->i_lock is not held over any other calls
      to d_move or __d_move so it can not provide any meaningful
      rename protection.

      dcache: Handle escaped paths in prepend_path

      A rename can result in a dentry that by walking up d_parent
      will never reach it's mnt_root.  For lack of a better term
      I call this an escaped path.

      prepend_path is called by four different functions __d_path,
      d_absolute_path, d_path, and getcwd.

      __d_path only wants to see paths are connected to the root it passes
      in.  So __d_path needs prepend_path to return an error.

      d_absolute_path similarly wants to see paths that are connected to
      some root.  Escaped paths are not connected to any mnt_root so
      d_absolute_path needs prepend_path to return an error greater
      than 1.  So escaped paths will be treated like paths on lazily
      unmounted mounts.

      getcwd needs to prepend "(unreachable)" so getcwd also needs
      prepend_path to return an error.

      d_path is the interesting hold out.  d_path just wants to print
      something, and does not care about the weird cases.  Which raises
      the question what should be printed?

      Given that <escaped_path>/<anything> should result in -ENOENT I
      believe it is desirable for escaped paths to be printed as empty
      paths.  As there are not really any meaninful path components when
      considered from the perspective of a mount tree.

      So tweak prepend_path to return an empty path with an new error
      code of 3 when it encounters an escaped path.

       [<     inlined    >] SyS_swapon+0x3c0/0x1850 SYSC_swapon 
mm/swapfile.c:2395
       [<ffffffff812242c0>] SyS_swapon+0x3c0/0x1850 mm/swapfile.c:2345
       [<ffffffff81e97c8a>] ia32_do_call+0x1b/0x25

      Looks like the swap_lock should be taken when iterating through the
      swap_info array on lines 2392 - 2401: q->swap_file may be reset to
      NULL by another thread before it is dereferenced for f_mapping.

      But why is that iteration needed at all?  Doesn't the claim_swapfile()
      which follows do all that is needed to check for a duplicate entry -
      FMODE_EXCL on a bdev, testing IS_SWAPFILE under i_mutex on a regfile?

      Well, not quite: bd_may_claim() allows the same "holder" to claim the
      bdev again, so we do need to use a different holder than "sys_swapon";
      and we should not replace appropriate -EBUSY by inappropriate -EINVAL.

      Index i was reused in a cpu loop further down: renamed cpu there.

      Netfilter updates for net-next

      This is second pull request includes the conflict resolution patch that
      resulted from the updates that we got for the conntrack template through
      kmalloc. No changes with regards to the previously sent 15 patches.

      The following patchset contains Netfilter updates for your net-next tree, 
they
      are:

      1) Rework the existing nf_tables counter expression to make it per-cpu.

      2) Prepare and factor out common packet duplication code from the TEE 
target so
         it can be reused from the new dup expression.

      3) Add the new dup expression for the nf_tables IPv4 and IPv6 families.

      4) Convert the nf_tables limit expression to use a token-based approach 
with
         64-bits precision.

      5) Enhance the nf_tables limit expression to support limiting at packet 
byte.
         This comes after several preparation patches.

      6) Add a burst parameter to indicate the amount of packets or bytes that 
can
         exceed the limiting.

      7) Add netns support to nfacct, from Andreas Schultz.

      8) Pass the nf_conn_zone structure instead of the zone ID in nf_tables to 
allow
         accessing more zone specific information, from Daniel Borkmann.

      9) Allow to define zone per-direction to support netns containers with
         overlapping network addressing, also from Daniel.

      10) Extend the CT target to allow setting the zone based on the skb->mark 
as a
         way to support simple mappings from iptables, also from Daniel.

      11) Make the nf_tables payload expression aware of the fact that VLAN 
offload
          may have removed a vlan header, from Florian Westphal.

      drm/dp/mst: dump branch OUI in debugfs (v2)

      It appears some MST docks are worse than other, but the only
      way to know is to see the sw revisions in here, so dump
      the branch OUI so we can look at the sw revision.

      v2: Thierry made me feel guilty, so I parsed the branch
      OUI.

      ARM: dts: UniPhier: fix PPI interrupt CPU mask of timer nodes

      This SoC is integrated with 4 Cortex-A9 cores.  The GIC bindings
      document says that the bits[15:8] of the 3rd cell of the interrupts
      property represents PPI interrupt CPU mask.  Because the timer
      interrupts are wired to all of the 4 cores, bits[15:8] should be set
      to 0xf.

      ARM: dts: rockchip: correct regulator power states for suspend

      When getting translated from a downstream device tree that used slightly
      different DT bindings, these regulators got labeled with the
      "on-in-suspend" state, when they were actually supposed to be turned off
      for S3 suspend. This was harmless, but not intentional, AFAICT.

      Let's turn them off to get the optimal power state.

      route: move lwtunnel state to dst_entry

      Currently, the lwtunnel state resides in per-protocol data. This is
      a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice 
versa).
      The xmit function of the tunnel does not know whether the packet has been
      routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the
      lwtstate data to dst_entry makes such inter-protocol tunneling possible.

      As a bonus, this brings a nice diffstat.

      PCI: Move MPS configuration check to pci_configure_device()

      Previously we checked for invalid MPS settings, i.e., a device with MPS
      different than its upstream bridge, in pcie_bus_detect_mps().  We only did
      this if the arch or hotplug driver called pcie_bus_configure_settings(),
      and then only if PCIe bus tuning was disabled (PCIE_BUS_TUNE_OFF).

      Move the MPS checking code to pci_configure_device(), so we do it in the
      pci_device_add() path for every device.

      irqchip/bcm2835: Refactor handle_IRQ() calls out of MAKE_HWIRQ

      For BCM2836, we want to chain into this IRQ chip from the root
      controller, and for chaining we need to do something else instead of
      handle_IRQ() once we have decoded the IRQ.

      Note that this changes the behavior a little bit: Previously for a
      non-shortcut IRQ, we'd loop reading and handling the second level IRQ
      status until it was cleared before returning to the loop reading the
      top level IRQ status (Note that the top level bit is just an OR of the
      low level bits).  For the expected case of just one interrupt to be
      handled, this was an extra register read, so we're down from 4 to 3
      reads.

      duplicate check which is already done by the lower/upper code, patch 3
      moves the ndo_add_slave code around a bit so we can drop an error
      label and patch 4 drops the master device checks which are unnecessary
      because the ops are taken from the master device itself so it can't be
      different.

      vrf: ndo_add|del_slave drop unnecessary checks

      When ndo_add|del_slave ops are used, they're taken from the respective
      master device's netdev ops, so if the master device is a VRF only then
      the VRF ops will get called thus no need to check the type of the
      master.

      stores to media using the PMEM API.  This ensures that the data DAX is

      pmem: add copy_from_iter_pmem() and clear_pmem()

      Add support for two new PMEM APIs, copy_from_iter_pmem() and
      clear_pmem().  copy_from_iter_pmem() is used to copy data from an
      iterator into a PMEM buffer.  clear_pmem() zeros a PMEM memory range.

      Both of these new APIs must be explicitly ordered using a wmb_pmem()
      function call and are implemented in such a way that the wmb_pmem()
      will make the stores to PMEM durable.  Because both APIs are unordered
      they can be called as needed without introducing any unwanted memory
      barriers.

      pmem, x86: clean up conditional pmem includes

      Prior to this change x86_64 used the pmem defines in
      arch/x86/include/asm/pmem.h, and UM used the default ones at the
      top of include/linux/pmem.h.  The inclusion or exclusion in linux/pmem.h
      was controlled by CONFIG_ARCH_HAS_PMEM_API, but the ones in asm/pmem.h
      were controlled by ARCH_HAS_NOCACHE_UACCESS.

      Instead, control them both with CONFIG_ARCH_HAS_PMEM_API so that it's
      clear that they are related and we don't run into the possibility where
      they are both included or excluded.  Also remove a bunch of stale
      function prototypes meant for UM in asm/pmem.h - these just conflicted
      with the inline defaults in linux/pmem.h and gave compile errors.

      spi: ti-qspi: use 128 bit transfer mode where possible

      TI QSPI has four 32 bit data regsiters which can be used to transfer 16
      bytes of data at once. The register group QSPI_SPI_DATA_REG_3,
      QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is
      treated as a single 128-bit word for shifting data in and out. The bit
      at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out
      in case of 128 bit transfer mode. Therefore the first byte to be written
      to flash should be at QSPI_SPI_DATA_REG_3[31-25] position.
      Instead of writing 1 byte at a time when interacting with spi-nor flash,
      make use of all the four registers so that 16 bytes can be transferred
      in one go. This reduces number of register writes and Word Complete
      interrupts for a given transfer message size, thereby increasing the
      write performance.

      Without this patch the raw flash write speed is ~100KB/s, with this
      patch the write speed increases to ~400 kB/s on DRA74 EVM.

      ARM/PCI, designware, xilinx: Use pci_scan_root_bus_msi()

      ARM previously stored the msi_controller pointer in its sysdata, struct
      pci_sys_data, and implemented pcibios_msi_controller() to retrieve it.
      That made PCI host controller drivers specific to ARM because they had to
      put the msi_controller pointer in the ARM-specific pci_sys_data.

      There is now a generic mechanism, pci_scan_root_bus_msi(), for giving the
      msi_controller pointer to the PCI core.  Use this for all ARM systems and
      for the DesignWare and Xilinx PCI host controller drivers.

      This removes an ARM dependency from the DesignWare, DRA7xx, EXYNOS, i.MX6,
      Keystone, Layerscape, SPEAr13xx, and Xilinx drivers.

      PCI: Add pci_scan_root_bus_msi()

      Add a pci_scan_root_bus_msi() interface so an arch can specify the MSI
      controller up front.  This removes the need for a pcibios callback to set
      the MSI controller later.

      This is not exported because I'd like to replace the variety of "scan root
      bus" interfaces with a single, more extensible interface that can handle
      the MSI controller, domain, pci_ops, resources, etc.  I hope this 
interface
      is temporary.

      ARM/PCI: Replace panic with WARN messages on failures

      In the ARM PCI bios32 layer, failures to dynamically allocate pci_sys_data
      for a PCI bus, or a PCI bus scan failure have to be considered serious
      warnings but they should not trigger a system panic so that at least the
      system is given a chance to be debugged.

      This patch replaces the panic statements with WARN() messages to improve
      error reporting in the ARM PCI bios32 layer.

      PCI: generic: Remove dependency on ARM-specific struct hw_pci

      The generic OF-based host controller driver uses pci_common_init_dev(),
      which is ARM-specific and requires the ARM struct hw_pci.  The part of
      pci_common_init_dev() that is needed is limited and can be done here
      without using hw_pci.

      Note that the ARM pcibios functions expect the PCI sysdata to be a pointer
      to a struct pci_sys_data.  Add a struct pci_sys_data as the first element
      in struct gen_pci so that when we use a gen_pci pointer as sysdata, it is
      also a pointer to a struct pci_sys_data.

      Create and scan the root bus directly without using the ARM
      pci_common_init_dev() interface.

      f2fs: check the node block address of newly allocated nid

      This patch adds a routine which checks the block address of newly 
allocated nid.
      If an nid has already allocated by other thread due to subtle data races, 
it
      will result in filesystem corruption.
      So, it needs to check whether its block address was already allocated or 
not

      ARC: change some branchs to jumps to resolve linkage errors

      When kernel's binary becomes large enough (32M and more) errors
      may occur during the final linkage stage. It happens because
      the build system uses short relocations for ARC  by default.
      This problem may be easily resolved by passing -mlong-calls
      option to GCC to use long absolute jumps (j) instead of short
      relative branchs (b).

      But there are fragments of pure assembler code exist which use
      branchs in inappropriate places and cause a linkage error because
      of relocations overflow.

      First of these fragments is .fixup insertion in futex.h and
      unaligned.c. It inserts a code in the separate section (.fixup)
      with branch instruction. It leads to the linkage error when
      kernel becomes large.

      Second of these fragments is calling scheduler's functions
      (common kernel code) from entry.S of ARC's code. When kernel's
      binary becomes large it may lead to the linkage error because
      scheduler may occur far enough from ARC's code in the final
      binary.

      udf: Don't modify filesystem for read-only mounts

      When read-write mount of a filesystem is requested but we find out we
      can mount the filesystem only in read-only mode, we still modify
      LVID in udf_close_lvid(). That is both unnecessary and contrary to
      expectation that when we fall back to read-only mount we don't modify
      the filesystem.

      Make sure we call udf_close_lvid() only if we called udf_open_lvid() so
      that filesystem gets modified only if we verified we are allowed to
      write to it.

      genksyms: Duplicate function pointer type definitions segfault

      I noticed that genksyms will segfault when it sees duplicate function
      pointer type declaration when I placed the same function pointer
      definition in two separate headers in a local branch as an intermediate
      step of some refactoring. This can be reproduced by piping the following
      minimal test case into `genksyms -r /dev/null` or alternatively, putting
      it into a C file attempting a build:

      typedef int (*f)();
      typedef int (*f)();

      Attaching gdb to genksyms to understand this failure is useless without
      changing CFLAGS to emit debuginfo. Once you have debuginfo, you will
      find that the failure is that `char *s` was NULL and the program
      executed `while(*s)`. At which point, further debugging requires
      familiarity with compiler front end / parser development.

      What happens is that flex identifies the first instance of the token "f"
      as IDENT and the yacc parser adds it to the symbol table. On the second
      instance, flex will identify "f" as TYPE, which triggers an error case
      in the yacc parser. Given that TYPE would have been IDENT had it not
      been in the symbol table, the the segmentaion fault could be avoided by
      treating TYPE as IDENT in the affected rule.

      Some might consider placing identical function pointer type declarations
      in different headers to be poor style might consider a failure to be
      beneficial. However, failing through a segmentation fault makes the
      cause non-obvious and can waste the time of anyone who encounters it.

      kbuild: Fix .text.unlikely placement

      When building a kernel with .text.unlikely text the unlikely text for
      each translation unit was put next to the main .text code in the
      final vmlinux.

      The problem is that the linker doesn't allow more specific submatches
      of a section name in a different linker script statement after the
      main match.

      So we need to move them all into one line. With that change
      .text.unlikely is at the end of everything again.

      I also moved .text.hot into the same statement though, even though
      that's not strictly needed.

      ARC: make futex_atomic_cmpxchg_inatomic() return bimodal

      Callers of cmpxchg_futex_value_locked() in futex code expect bimodal
      return value:
        !0 (essentially -EFAULT as failure)
         0 (success)

      Before this patch, the success return value was old value of futex,
      which could very well be non zero, causing caller to possibly take the
      failure path erroneously.

      Fix that by returning 0 for success

      (This fix was done back in 2011 for all upstream arches, which ARC
      obviously missed)

      ARCv2: Support IO Coherency and permutations involving L1 and L2 caches

      In case of ARCv2 CPU there're could be following configurations
      that affect cache handling for data exchanged with peripherals
      via DMA:
       [1] Only L1 cache exists
       [2] Both L1 and L2 exist, but no IO coherency unit
       [3] L1, L2 caches and IO coherency unit exist

      Current implementation takes care of [1] and [2].
      Moreover support of [2] is implemented with run-time check
      for SLC existence which is not super optimal.

      This patch introduces support of [3] and rework of DMA ops
      usage. Instead of doing run-time check every time a particular
      DMA op is executed we'll have 3 different implementations of
      DMA ops and select appropriate one during init.

      As for IOC support for it we need:
       [a] Implement empty DMA ops because IOC takes care of cache
           coherency with DMAed data
       [b] Route dma_alloc_coherent() via dma_alloc_noncoherent()
           This is required to make IOC work in first place and also
           serves as optimization as LD/ST to coherent buffers can be
           srviced from caches w/o going all the way to memory

      Map shared data structure that will hold CPU registers, VPMU context,

      xen: allow more than 512 GB of RAM for 64 bit pv-domains

      64 bit pv-domains under Xen are limited to 512 GB of RAM today. The
      main reason has been the 3 level p2m tree, which was replaced by the
      virtual mapped linear p2m list. Parallel to the p2m list which is
      being used by the kernel itself there is a 3 level mfn tree for usage
      by the Xen tools and eventually for crash dump analysis. For this tree
      the linear p2m list can serve as a replacement, too. As the kernel
      can't know whether the tools are capable of dealing with the p2m list
      instead of the mfn tree, the limit of 512 GB can't be dropped in all
      cases.

      This patch replaces the hard limit by a kernel parameter which tells
      the kernel to obey the 512 GB limit or not. The default is selected by
      a configuration parameter which specifies whether the 512 GB limit
      should be active per default for domUs (domain save/restore/migration
      and crash dump analysis are affected).

      Memory above the domain limit is returned to the hypervisor instead of
      being identity mapped, which was wrong anyway.

      The kernel configuration parameter to specify the maximum size of a
      domain can be deleted, as it is not relevant any more.

      As the p2m list might by huge (up to several GB) and is required to be
      mapped virtually, set up a temporary mapping for the copied list.

      For pvh domains just delete the p2m related information from start
      info instead of reserving the p2m memory, as we don't need it at all.

      For 32 bit kernels adjust the memblock_reserve() parameters in order

      xen: add explicit memblock_reserve() calls for special pages

      Some special pages containing interfaces to xen are being reserved
      implicitly only today. The memblock_reserve() call to reserve them is
      meant to reserve the p2m list supplied by xen. It is just reserving
      not only the p2m list itself, but some more pages up to the start of
      the xen built page tables.

      To be able to move the p2m list to another pfn range, which is needed
      for support of huge RAM, this memblock_reserve() must be split up to
      cover all affected reserved pages explicitly.

      The affected pages are:
      - start_info page
      - xenstore ring (might be missing, mfn is 0 in this case)
      - console ring (not for initial domain)

      xen: split counting of extra memory pages from remapping

      Memory pages in the initial memory setup done by the Xen hypervisor
      conflicting with the target E820 map are remapped. In order to do this
      those pages are counted and remapped in xen_set_identity_and_remap().

      Split the counting from the remapping operation to be able to setup
      the needed memory sizes in time but doing the remap operation at a
      later time. This enables us to simplify the interface to
      xen_set_identity_and_remap() as the number of remapped and released
      pages is no longer needed here.

      Finally move the remapping further down to prepare relocating
      conflicting memory contents before the memory might be clobbered by
      xen_set_identity_and_remap(). This requires to not destroy the Xen
      E820 map when the one for the system is being constructed.

      xen: eliminate scalability issues from initial mapping setup

      Direct Xen to place the initial P->M table outside of the initial
      mapping, as otherwise the 1G (implementation) / 2G (theoretical)
      restriction on the size of the initial mapping limits the amount
      of memory a domain can be handed initially.

      As the initial P->M table is copied rather early during boot to
      domain private memory and it's initial virtual mapping is dropped,
      the easiest way to avoid virtual address conflicts with other
      addresses in the kernel is to use a user address area for the
      virtual address of the initial P->M table. This allows us to just
      throw away the page tables of the initial mapping after the copy
      without having to care about address invalidation.

      It should be noted that this patch won't enable a pv-domain to USE
      more than 512 GB of RAM. It just enables it to be started with a
      P->M table covering more memory. This is especially important for
      being able to boot a Dom0 on a system with more than 512 GB memory.

      xen: save linear p2m list address in shared info structure

      The virtual address of the linear p2m list should be stored in the
      shared info structure read by the Xen tools to be able to support
      64 bit pv-domains larger than 512 GB. Additionally the linear p2m
      list interface includes a generation count which is changed prior
      to and after each mapping change of the p2m list. Reading the
      generation count the Xen tools can detect changes of the mappings
      and re-read the p2m list eventually.

      xen/events: Support event channel rebind on ARM

      Currently, the event channel rebind code is gated with the presence of
      the vector callback.

      The virtual interrupt controller on ARM has the concept of per-CPU
      interrupt (PPI) which allow us to support per-VCPU event channel.
      Therefore there is no need of vector callback for ARM.

      Xen is already using a free PPI to notify the guest VCPU of an event.
      Furthermore, the xen code initialization in Linux (see
      arch/arm/xen/enlighten.c) is requesting correctly a per-CPU IRQ.

      Introduce new helper xen_support_evtchn_rebind to allow architecture
      decide whether rebind an event is support or not. It will always return
      true on ARM and keep the same behavior on x86.

      This is also allow us to drop the usage of xen_have_vector_callback
      entirely in the ARM code.

      powerpc/hvsi: Fix endianness issues in the HVSI driver

      This patch fixes several endianness issues detected when running the HVSI
      driver in little endian mode.

      These issues are raised in little endian mode because the data exchanged 
in
      memory between the kernel and the hypervisor has to be in big endian
      format. This exhibits as errors such as:

        irq: (null) didn't like hwirq-0x1000a00 to VIRQ16 mapping (rc=-22)
        hvsi_console_init: couldn't create irq mapping for 0x1000a00

      The data structures already have endian annotations, and sparse is
      generating numerous warnings based on those. This commit fixes all of
      them.

      leds/powernv: Add driver for PowerNV platform

      This patch implements LED driver for PowerNV platform using the existing
      generic LED class framework.

      PowerNV platform has below type of LEDs:
        - System attention
            Indicates there is a problem with the system that needs attention.
        - Identify
            Helps the user locate/identify a particular FRU or resource in the
            system.
        - Fault
            Indicates there is a problem with the FRU or resource at the
            location with which the indicator is associated.

      We register classdev structures for all individual LEDs detected on the
      system through LED specific device tree nodes. Device tree nodes specify
      what all kind of LEDs present on the same location code. It registers
      LED classdev structure for each of them.

      All the system LEDs can be found in the same regular path 
/sys/class/leds/.
      We don't use LED colors. We use LED node and led-types property to form
      LED classdev. Our LEDs have names in this format.

              <location_code>:<attention|identify|fault>

      Any positive brightness value would turn on the LED and a zero value would
      turn off the LED. The driver will return LED_FULL (255) for any turned on
      LED and LED_OFF (0) for any turned off LED.

      The platform level implementation of LED get and set state has been

      fbdev: fix cea_modes array size

      CEA defines 64 modes, indexed from 1 to 64. modedb has cea_modes arrays,
      which contains 64 entries. However, the code uses the CEA indices
      directly, i.e. the first mode is at cea_modes[1]. This means the array
      is one too short.

      This does not cause references to uninitialized memory as the code in
      fbmon only allows indexes up to 63, and the cea_modes does not contain
      an entry for the mode 64 so it could not be used in any case.

      However, the code contains a check 'if (idx > ARRAY_SIZE(cea_modes)',
      and while that check is a no-op as at that point idx cannot be >= 63, it
      upsets static checkers.

      Fix this by increasing the cea_array size to be 65, and change the code
      to allow mode 64.

      dmaengine: tegra-apb: Simplify locking for device using global pause

      Sparse reports the following with regard to locking in the
      tegra_dma_global_pause() and tegra_dma_global_resume() functions:

      drivers/dma/tegra20-apb-dma.c:362:9: warning: context imbalance in
        'tegra_dma_global_pause' - wrong count at exit
      drivers/dma/tegra20-apb-dma.c:366:13: warning: context imbalance in
        'tegra_dma_global_resume' - unexpected unlock

      The warning is caused because tegra_dma_global_pause() acquires a lock
      but does not release it. However, the lock is released by
      tegra_dma_global_resume(). These pause/resume functions are called in
      pairs and so it does appear to work.

      This global pause is used on early tegra devices that do not have an
      individual pause for each channel. The lock appears to be used to ensure
      that multiple channels do not attempt to assert/de-assert the global pause
      at the same time which could cause the DMA controller to be in the wrong
      paused state. Rather than locking around the entire code between the pause
      and resume, employ a simple counter to keep track of the global pause
      requests. By using a counter, it is only necessary to hold the lock when
      pausing and unpausing the DMA controller and hence, fixes the sparse
      warning.

      Please note that for devices that support individual channel pausing, the
      DMA controller lock is not held between pausing and unpausing the channel.
      Hence, this change will make the devices that use the global pause behave
      in the same way, with regard to locking, as those that don't.

      dmaengine: Stricter legacy checking in dma_request_slave_channel_compat()

      dma_request_slave_channel_compat() is meant for drivers that support
      both DT and legacy platform device based probing: if DT channel DMA
      setup fails, it will fall back to platform data based DMA channel setup,
      using hardcoded DMA channel IDs and a filter function.

      However, if the DTS doesn't provide a "dmas" property for the device,
      the fallback is also used. If the legacy filter function is not
      hardcoded in the DMA slave driver, but comes from platform data, it will
      be NULL. Then dma_request_slave_channel_compat() will succeed
      incorrectly, and return a DMA channel, as a NULL legacy filter function
      actually means "all channels are OK", not "do not match".

      Later, when trying to use that DMA channel, it will fail with:

          rcar-dmac e6700000.dma-controller: rcar_dmac_prep_slave_sg: bad 
parameter: len=1, id=-22

      To fix this, ensure that both the filter function and the DMA channel ID
      are not NULL before using the legacy fallback.

      Note that some DMA slave drivers can handle this failure, and will fall
      back to PIO.

      See also commit 056f6c87028544de ("dmaengine: shdma: Make dummy
      shdma_chan_filter() always return false"), which fixed the same issue
      for the case where shdma_chan_filter() is hardcoded in a DMA slave
      driver.

      cxl: Allow release of contexts which have been OPENED but not STARTED

      If we open a context but do not start it (either because we do not attempt
      to start it, or because it fails to start for some reason), we are left
      with a context in state OPENED. Previously, cxl_release_context() only
      allowed releasing contexts in state CLOSED, so attempting to release an
      OPENED context would fail.

      In particular, this bug causes available contexts to run out after some 
EEH
      failures, where drivers attempt to release contexts that have failed to
      start.

      Allow releasing contexts in any state with a value lower than STARTED, 
i.e.
      OPENED or CLOSED (we can't release a STARTED context as it's currently
      using the hardware, and we assume that contexts in any new states which 
may
      be added in future with a value higher than STARTED are also unsafe to
      release).

      macintosh/therm_windtunnel: Export OF module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      Unlike the previous attempt, this takes into account the fact that
      we may be calling it from the recovery thread itself. Detect this
      by looking at what kind of open we're doing, and checking the state
      of the NFS_DELEGATION_NEED_RECLAIM if it turns out we're doing a

      drm/layerscape: Add Freescale DCU DRM driver

      This patch add support for Two Dimensional Animation and Compositing
      Engine (2D-ACE) on the Freescale SoCs.

      2D-ACE is a Freescale display controller. 2D-ACE describes
      the functionality of the module extremely well its name is a value
      that cannot be used as a token in programming languages.
      Instead the valid token "DCU" is used to tag the register names and
      function names.

      The Display Controller Unit (DCU) module is a system master that
      fetches graphics stored in internal or external memory and displays
      them on a TFT LCD panel. A wide range of panel sizes is supported
      and the timing of the interface signals is highly configurable.
      Graphics are read directly from memory and then blended in real-time,
      which allows for dynamic content creation with minimal CPU
      intervention.

      The features:
      (1) Full RGB888 output to TFT LCD panel.
      (2) Blending of each pixel using up to 4 source layers
      dependent
      on size of panel.
      (3) Each graphic layer can be placed with one pixel resolution
      in either axis.
      (4) Each graphic layer support RGB565 and RGB888 direct colors
      without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct
      colors
      with an alpha channel and YUV422 format.
      (5) Each graphic layer support alpha blending with 8-bit
      resolution.
      This is a simplified version, only one primary plane, one
      framebuffer, one crtc, one connector and one encoder for TFT
      LCD panel.

      When CONFIG_LWTUNNEL config is not enabled, the lwtstate_free() is not
      declared in lwtunnel.h at all. However, even in this case, the function
      is still referenced in fib_semantics.c so that there appears the
      following sparse warnings:

      net/ipv4/fib_semantics.c:553:17: error: undefined identifier 
'lwtstate_free'

        make[1]: *** [net/ipv4/fib_semantics.o] Error 1
        make: *** [net/ipv4/fib_semantics.o] Error 2

      To eliminate the error, we define an empty function for lwtstate_free()
      in lwtunnel.h when CONFIG_LWTUNNEL is disabled.

      The read ID count should be made as large as the maximum READ_ID size,
      so there's no need to have dynamic size. This commit sets the hardware
      maximum read ID count, which should be more than enough on all cases.
      Also, we get rid of the read_id_bytes, and use a macro instead.

      mtd: nand: pxa3xx-nand: fix random command timeouts

      When 2 commands are submitted in a row, and the second is very quick,
      the completion of the second command might never come. This happens
      especially if the second command is quick, such as a status read after
      an erase.

      The issue is that in the interrupt handler, the status bits are cleared
      after the new command is issued. There is a small temporal window where
      this happens :
       - the previous command has set the command done bit
       - the ready for a command bit is set
       - the handler submits the next command
         - just then, the command completes, and the command done bit is still
           set
       - the handler clears the "previous" command done bit
       - the handler exits

      In this flow, the "command done" of the next command will never trigger
      a new interrupt to finish the status command, as it was cleared for both
      commands.

      Fix this by clearing the status bit before submitting a new command.

      mtd: nand: pxa3xx_nand: fix early spurious interrupt

      When the nand is first probe, and upon the first command start, the
      status bits should be cleared before the interrupts are unmasked.

      The bug is tricky : if the bootloader left a status bit set, the
      unmasking of interrupts does trigger the interrupt handler before the
      first command is issued, blocking the good behavior of the nand.

      The same would happen if in pxa3xx_nand code flow a status bit is left,
      and then a command is started.

      Btrfs: fix file read corruption after extent cloning and fsync

      If we partially clone one extent of a file into a lower offset of the
      file, fsync the file, power fail and then mount the fs to trigger log
      replay, we can get multiple checksum items in the csum tree that overlap
      each other and result in checksum lookup failures later. Those failures
      can make file data read requests assume a checksum value of 0, but they
      will not return an error (-EIO for example) to userspace exactly because
      the expected checksum value 0 is a special value that makes the read bio
      endio callback return success and set all the bytes of the corresponding
      page with the value 0x01 (at fs/btrfs/inode.c:__readpage_endio_check()).
      From a userspace perspective this is equivalent to file corruption
      because we are not returning what was written to the file.

      Details about how this can happen, and why, are included inline in the
      following reproducer test case for fstests and the comment added to
      tree-log.c.

      Btrfs: check if previous transaction aborted to avoid fs corruption

      While we are committing a transaction, it's possible the previous one is
      still finishing its commit and therefore we wait for it to finish first.
      However we were not checking if that previous transaction ended up getting
      aborted after we waited for it to commit, so we ended up committing the
      current transaction which can lead to fs corruption because the new
      superblock can point to trees that have had one or more nodes/leafs that
      were never durably persisted.
      The following sequence diagram exemplifies how this is possible:

                CPU 0

some root that uses eb X, which was
                                                                            
never written to disk

      In this scenario future attempts to read eb X from disk results in an
      error message like "parent transid verify failed on X wanted Y found Z".

      So fix this by aborting the current transaction if after waiting for the
      previous transaction we verify that it was aborted.

      block: Replace SG_GAPS with new queue limits mask

      The SG_GAPS queue flag caused checks for bio vector alignment against
      PAGE_SIZE, but the device may have different constraints. This patch
      adds a queue limits so a driver with such constraints can set to allow
      requests that would have been unnecessarily split. The new gaps check
      takes the request_queue as a parameter to simplify the logic around
      invoking this function.

      This new limit makes the queue flag redundant, so removing it and
      all usage. Device-mappers will inherit the correct settings through
      blk_stack_limits().

      btrfs: use __GFP_NOFAIL in alloc_btrfs_bio

      alloc_btrfs_bio relies on GFP_NOFS allocation when committing the
      transaction but this allocation context is rather weak wrt. reclaim
      capabilities. The page allocator currently tries hard to not fail these
      allocations if they are small (<=PAGE_ALLOC_COSTLY_ORDER) but it can
      still fail if the _current_ process is the OOM killer victim. Moreover
      there is an attempt to move away from the default no-fail behavior and
      allow these allocation to fail more eagerly. This would lead to:

      [   37.928625] kernel BUG at fs/btrfs/extent_io.c:4045

      which is clearly undesirable and the nofail behavior should be explicit
      if the allocation failure cannot be tolerated.

      this allocation context is rather weak wrt. reclaim capabilities. The
      page allocator currently tries hard to not fail these allocations if

      btrfs: Remove useless condition in start_log_trans()

      Dan Carpenter <dan.carpenter@xxxxxxxxxx> reported a smatch warning
      for start_log_trans():
       fs/btrfs/tree-log.c:178 start_log_trans()
       warn: we tested 'root->log_root' before and it was 'false'

       fs/btrfs/tree-log.c
       147          if (root->log_root) {
       We test "root->log_root" here.
       ...

      Reason:
       Condition of:
       fs/btrfs/tree-log.c:178: if (!root->log_root) {
       is not necessary after commit: 7237f1833

       It caused a smatch warning, and no functionally error.

      Fix:
       Deleting above condition will make smatch shut up,
       but a better way is to do cleanup for start_log_trans()
       to remove duplicated code and make code more readable.

      Input: cros_ec_keyb - replace KEYBOARD_CROS_EC dependency

      The ChromeOS EC keyboard driver config depends on CROS_EC_PROTO but
      MFD_CROS_EC selects CROS_EC_PROTO instead. Mixing select and depends
      on is bad practice as it may lead to circular Kconfig dependencies.

      Since the platform device that is matched with the keyboard driver
      is registered by the ChromeOS EC mfd driver, KEYBOARD_CROS_EC really
      should depend on MFD_CROS_EC. And because this config option selects
      CROS_EC_PROTO, that dependency is met as well. So make the driver
      to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

      netfilter: bridge: fix IPv6 packets not being bridged with CONFIG_IPV6=n

      230ac490f7fba introduced a dependency to CONFIG_IPV6 which breaks bridging
      of IPv6 packets on a bridge with CONFIG_IPV6=n.

      Sysctl entry /proc/sys/net/bridge/bridge-nf-call-ip6tables defaults to 1,
      for this reason packets are handled by br_nf_pre_routing_ipv6(). When 
compiled
      with CONFIG_IPV6=n this function returns NF_DROP but should return 
NF_ACCEPT
      to let packets through.

      Change CONFIG_IPV6=n br_nf_pre_routing_ipv6() return value to NF_ACCEPT.

      Tested with a simple bridge with two interfaces and IPv6 packets trying
      to pass from host on left side to host on right side of the bridge.

      dmaengine: mv_xor: optimize performance by using a subset of the XOR 
channels

      Due to how async_tx behaves internally, having more XOR channels than
      CPUs is actually hurting performance more than it improves it, because
      memcpy requests get scheduled on a different channel than the XOR
      requests, but async_tx will still wait for the completion of the
      memcpy requests before scheduling the XOR requests.

      It is in fact more efficient to have at most one channel per CPU,
      which this patch implements by limiting the number of channels per
      engine, and the number of engines registered depending on the number
      of availables CPUs.

      Marvell platforms are currently available in one CPU, two CPUs and
      four CPUs configurations:

       - in the configurations with one CPU, only one channel from one
         engine is used.

       - in the configurations with two CPUs, only one channel from each
         engine is used (they are two XOR engines)

       - in the configurations with four CPUs, both channels of both engines
         are used.

      dmaengine: mv_xor: remove support for dmacap,* DT properties

      The only reason why we had dmacap,* properties is because back when
      DMA_MEMSET was supported, only one out of the two channels per engine
      could do a memset operation. But this is something that the driver
      already knows anyway, and since then, the DMA_MEMSET support has been
      removed.

      The driver is already well aware of what each channel supports and the
      one to one mapping between Linux specific implementation details (such
      as dmacap,interrupt enabling DMA_INTERRUPT) and DT properties is a
      good indication that these DT properties are wrong.

      Therefore, this commit simply gets rid of these dmacap,* properties,
      they are now ignored, and the driver is responsible for knowing the
      capabilities of the hardware with regard to the dmaengine subsystem
      expectations.

      dmaengine: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      If layout is marked by NFS_LAYOUT_RETURN_BEFORE_CLOSE, we should always
      send LAYOUTRETURN before close, and we don't need to do ROC drain if we
      do send LAYOUTRETURN.

      kconfig: Regenerate shipped zconf.{hash,lex}.c files

      Update the shipped files generated by flex and gperf to support the
      explicit use of "---help---" and to emit warnings for unsupported
      characters on COMMAND tokens.

      As I could not find out which flex/gperf version was used to generate
      the previous version, I used flex 2.5.35  and gperf 3.0.4 from
      Ubuntu 14.04 - this also leads to the big number of changed lines
      in this patch.

      kconfig: warn of unhandled characters in Kconfig commands

      In Kconfig, definitions of options take the following form:
      "<COMMAND> <PARAM> <PARAM> ...". COMMANDs and PARAMs are treated
      slightly different by the underlying parser.

      While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled
      characters") introduced a warning for unsupported characters around
      PARAMs, it does not cover situations where a COMMAND has additional
      characters before it.

      This change makes Kconfig emit a warning if superfluous characters
      are found before COMMANDs. As the 'help' statement sometimes is
      written as '---help---', the '-' character would now also be regarded
      as unhandled and generate a warning. To avoid that, '-' is added to
      the list of allowed characters, and the token '---help---' is included
      in the zconf.gperf file.

      s390/mm: simplify page table alloc/free code

      With the removal of the dynamic reallocation of page tables for
      KVM (see git commit 0b46e0a3ec0d7a04af6a091354f1b5e1b952d70a)
      the page table allocation / freeing code can be simplified.

      The page table free code can now use the alloc_pgste bit in the
      mm context to decide if a page table is 2K or 4K, there is no mix
      of different sized page tables anymore. This eliminates the need
      to use "page->_mapcount == 0" to check for 4K page table.

      Use the lower two bits in page->_mapcount to indicate which
      2K fragments of the 4K page are in use.

      As 31-bit support is gone, remove the two defines ALLOC_ORDER
      and FRAG_MASK and use the constants directly where appropriate.

      s390/hmcdrv: fix interrupt registration

      The z/VM driver sets bit "63-22" in control register zero to one in order
      to enable the CP Service interrupt (0x2603). However the irq subclass mask
      that normally corresponds to the CP Service interrupt is
      "63-54" (== "63-22-32").

      So it looks like the author read the documentation with the 32 bit sized
      cr0 register bit positions (== 22), but didn't realize that bit numbers
      change, if applied to a 64 bit register (== 54) due to the numbering
      scheme.

      Also use irq_subclass_register() instead if ctl_set_bit() since multiple
      services depend on the service signal subclass mask, which is the correct
      bit. This also explains why nobody noticed the bug, since the bit is 
always
      enabled anyway (e.g. pfault).

      NFSv4.1/pnfs: Play safe w.r.t. close() races when return-on-close is set

      If we have an OPEN_DOWNGRADE and CLOSE race with one another, we want
      to ensure that the layout is forgotten by the client, so that we
      start afresh with a new layoutget.

      libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option

      We currently register a platform device for e820 type-12 memory and
      register a nvdimm bus beneath it.  Registering the platform device
      triggers the device-core machinery to probe for a driver, but that
      search currently comes up empty.  Building the nvdimm-bus registration
      into the e820_pmem platform device registration in this way forces
      libnvdimm to be built-in.  Instead, convert the built-in portion of
      CONFIG_X86_PMEM_LEGACY to simply register a platform device and move the
      rest of the logic to the driver for e820_pmem, for the following
      reasons:

      1/ Letting e820_pmem support be a module allows building and testing
         libnvdimm.ko changes without rebooting

      2/ All the normal policy around modules can be applied to e820_pmem
         (unbind to disable and/or blacklisting the module from loading by
         default)

      3/ Moving the driver to a generic location and converting it to scan
         "iomem_resource" rather than "e820.map" means any other architecture 
can
         take advantage of this simple nvdimm resource discovery mechanism by
         registering a resource named "Persistent Memory (legacy)"

      NFSv4.1/pnfs: Fix a close/delegreturn hang when return-on-close is set

      The helper pnfs_roc() has already verified that we have no delegations,
      and no further open files, hence no outstanding I/O and it has marked
      all the return-on-close lsegs as being invalid.
      Furthermore, it sets the NFS_LAYOUT_RETURN bit, thus serialising the
      close/delegreturn with all future layoutget calls on this inode.

      The checks in pnfs_roc_drain() for valid layout segments are therefore
      redundant: those cannot exist until another layoutget completes.
      The other check for whether or not NFS_LAYOUT_RETURN is set, actually
      causes a hang, since we already know that we hold that flag.

      To fix, we therefore strip out all the functionality in pnfs_roc_drain()
      except the retrieval of the barrier state, and then rename the function
      accordingly.

      Intel Wired LAN Driver Updates 2015-08-18

      This series contains updates to igb, e100, e1000e and ixgbe.

      Shota Suzuki provides a fix for a possible overflow in
      igb_set_interrupt_capability() which leads to an oops.  When changing the
      number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same
      manner as when initializing the igb driver.

      Vasily Averin provides a fix for a missing rtnl_unlock() for when we
      error out due to not being able to allocate memory for our queues.

      Stefan Assman provides a couple of fixes for igb/igbvf.  First changes
      the igb driver in probe to simply call igb_enable_sriov() instead of
      igb_sriov_reinit() since we are starting from scratch.  Then in igbvf,
      fix the driver where it does not clear the buffer_info->dma in all
      cases after calling dma_unmap_single(), which was found by changing the
      MTU twice.

      Richard Cochran implements the periodic output function using the
      programmable clock outputs available in i210 when possible, falling
      back to the target time for longer periods.

      Todd adds support for the Marvell PHY 1512 which is required for i354
      devices.  Then updates igb to make sure SR-IOV init uses the correct
      number of queues, since recent changes could result in the PF holding
      onto all of the queues.

      Alex Williamson provides a fix in the case where a guest OS does not
      support hot-unplug, so disable SR-IOV prior to unregister_netdev() to
      avoid the problem.

      Jia-Ju Bai provides several patches, first knocks some collecting dust
      off an old e100 driver to add a check to avoid a null pointer
      dereference.  Then cleans up a possible resource leak by releasing the
      skb buffer allocated when the e100_xmit_prepare() runs into an issue
      in the DMA mapping.  In igb, add a missing rtnl_unlock() for when we
      error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme().
      Provides a e1000e fix, based on suggestions from Alex Duyck to move
      head/tail register writing to e1000_configure_tx/rx() to avoid a
      possible null pointer dereference (similar to igb driver).  Lastly,
      fix a possible memory leak in igb_probe(), where the memory shadow_vfta
      allocated by kcalloc in igb_sw_init() is not freed.

      Mark simplifies port-specific macros for ixgbe by eliminating explicit
      comparisons with 0 and enclose formal parameters in parens to eliminate
      the risk of an operator precedence issue.

      lwtunnel: ip tunnel: fix multiple routes with different encap

      Currently, two routes going through the same tunnel interface are 
considered
      the same even when they are routed to a different host after 
encapsulation.
      This causes all routes added after the first one to have incorrect
      encapsulation parameters.

        # ip r a 192.168.1.2/32 dev vxlan0 tunnel dst 10.0.0.2
        # ip r a 192.168.1.3/32 dev vxlan0 tunnel dst 10.0.0.3

      xfs: flush entire file on dio read/write to cached file

      Filesystems are responsible to manage file coherency between the page
      cache and direct I/O. The generic dio code flushes dirty pages over the
      range of a dio to ensure that the dio read or a future buffered read
      returns the correct data. XFS has generally followed this pattern,
      though traditionally has flushed and invalidated the range from the
      start of the I/O all the way to the end of the file. This changed after
      the following commit:

        7d4ea3ce xfs: use ranged writeback and invalidation for direct IO

      ... as the full file flush was no longer necessary to deal with the
      strange post-eof delalloc issues that were since fixed. Unfortunately,
      we have since received complaints about performance degradation due to
      the increased exclusive iolock cycles (which locks out parallel dio
      submission) that occur when a file has cached pages. This does not occur
      on filesystems that use the generic code as it also does not incorporate
      locking.

      The exclusive iolock is acquired any time the inode mapping has cached
      pages, regardless of whether they reside in the range of the I/O or not.
      If not, the flush/inval calls do no work and the lock was cycled for no
      reason.

      Under consideration of the cost of the exclusive iolock, update the dio
      read and write handlers to flush and invalidate the entire mapping when
      cached pages exist. In most cases, this increases the cost of the
      initial flush sequence but eliminates the need for further lock cycles
      and flushes so long as the workload does not actively mix direct and
      buffered I/O. This also more closely matches historical behavior and
      performance characteristics that users have come to expect.

      xfs: Fix xfs_attr_leafblock definition

      struct xfs_attr_leafblock contains 'entries' array which is declared
      with size 1 altough it can in fact contain much more entries. Since this
      array is followed by further struct members, gcc (at least in version
      4.8.3) thinks that the array has the fixed size of 1 element and thus
      may optimize away all accesses beyond the end of array resulting in
      non-working code. This problem was only observed with userspace code in
      xfsprogs, however it's better to be safe in kernel as well and have
      matching kernel and xfsprogs definitions.

      xfs: stop holding ILOCK over filldir callbacks

      The recent change to the readdir locking made in 40194ec ("xfs:
      reinstate the ilock in xfs_readdir") for CXFS directory sanity was
      probably the wrong thing to do. Deep in the readdir code we
      can take page faults in the filldir callback, and so taking a page
      fault while holding an inode ilock creates a new set of locking
      issues that lockdep warns all over the place about.

      The locking order for regular inodes w.r.t. page faults is io_lock
      -> pagefault -> mmap_sem -> ilock. The directory readdir code now
      triggers ilock -> page fault -> mmap_sem. While we cannot deadlock
      at this point, it inverts all the locking patterns that lockdep
      normally sees on XFS inodes, and so triggers lockdep. We worked
      around this with commit 93a8614 ("xfs: fix directory inode iolock
      lockdep false positive"), but that then just moved the lockdep
      warning to deeper in the page fault path and triggered on security
      inode locks. Fixing the shmem issue there just moved the lockdep
      reports somewhere else, and now we are getting false positives from
      filesystem freezing annotations getting confused.

      Further, if we enter memory reclaim in a readdir path, we now get
      lockdep warning about potential deadlocks because the ilock is held
      when we enter reclaim. This, again, is different to a regular file
      in that we never allow memory reclaim to run while holding the ilock
      for regular files. Hence lockdep now throws
      ilock->kmalloc->reclaim->ilock warnings.

      Basically, the problem is that the ilock is being used to protect
      the directory data and the inode metadata, whereas for a regular
      file the iolock protects the data and the ilock protects the
      metadata. From the VFS perspective, the i_mutex serialises all
      accesses to the directory data, and so not holding the ilock for
      readdir doesn't matter. The issue is that CXFS doesn't access
      directory data via the VFS, so it has no "data serialisaton"
      mechanism. Hence we need to hold the IOLOCK in the correct places to
      provide this low level directory data access serialisation.

      The ilock can then be used just when the extent list needs to be
      read, just like we do for regular files. The directory modification
      code can take the iolock exclusive when the ilock is also taken,
      and this then ensures that readdir is correct excluded while
      modifications are in progress.

      xfs: clean up inode lockdep annotations

      Lockdep annotations are a maintenance nightmare. Locking has to be
      modified to suit the limitations of the annotations, and we're
      always having to fix the annotations because they are unable to
      express the complexity of locking heirarchies correctly.

      So, next up, we've got more issues with lockdep annotations for
      inode locking w.r.t. XFS_LOCK_PARENT:

        - lockdep classes are exclusive and can't be ORed together
          to form new classes.
        - IOLOCK needs multiple PARENT subclasses to express the
          changes needed for the readdir locking rework needed to
          stop the endless flow of lockdep false positives involving
          readdir calling filldir under the ILOCK.
        - there are only 8 unique lockdep subclasses available,
          so we can't create a generic solution.

      IOWs we need to treat the 3-bit space available to each lock type
      differently:

        - IOLOCK uses xfs_lock_two_inodes(), so needs:
                - at least 2 IOLOCK subclasses
                - at least 2 IOLOCK_PARENT subclasses
        - MMAPLOCK uses xfs_lock_two_inodes(), so needs:
                - at least 2 MMAPLOCK subclasses
        - ILOCK uses xfs_lock_inodes with up to 5 inodes, so needs:
                - at least 5 ILOCK subclasses
                - one ILOCK_PARENT subclass
                - one RTBITMAP subclass
                - one RTSUM subclass

      For the IOLOCK, split the space into two sets of subclasses.
      For the MMAPLOCK, just use half the space for the one subclass to
      match the non-parent lock classes of the IOLOCK.
      For the ILOCK, use 0-4 as the ILOCK subclasses, 5-7 for the
      remaining individual subclasses.

      Because they are now all different, modify xfs_lock_inumorder() to
      handle the nested subclasses, and to assert fail if passed an
      invalid subclass. Further, annotate xfs_lock_inodes() to assert fail
      if an invalid combination of lock primitives and inode counts are
      passed that would result in a lockdep subclass annotation overflow.

      xfs: swap leaf buffer into path struct atomically during path shift

      The node directory lookup code uses a state structure that tracks the
      path of buffers used to search for the hash of a filename through the
      leaf blocks. When the lookup encounters a block that ends with the
      requested hash, but the entry has not yet been found, it must shift over
      to the next block and continue looking for the entry (i.e., duplicate
      hashes could continue over into the next block). This shift mechanism
      involves walking back up and down the state structure, replacing buffers
      at the appropriate btree levels as necessary.

      When a buffer is replaced, the old buffer is released and the new buffer
      read into the active slot in the path structure. Because the buffer is
      read directly into the path slot, a buffer read failure can result in
      setting a NULL buffer pointer in an active slot. This throws off the
      state cleanup code in xfs_dir2_node_lookup(), which expects to release a
      buffer from each active slot. Instead, a BUG occurs due to a NULL
      pointer dereference:

        BUG: unable to handle kernel NULL pointer dereference at 
00000000000001e8

         ...

      This has been reproduced via a parallel fsstress and filesystem shutdown
      workload in a loop. The shutdown triggers the read error in the
      aforementioned codepath and causes the BUG in xfs_dir2_node_lookup().

      Update xfs_da3_path_shift() to update the active path slot atomically
      with respect to the caller when a buffer is replaced. This ensures that
      the caller always sees the old or new buffer in the slot and prevents
      the NULL pointer dereference.

      xfs: relocate sparse inode mount warning

      The sparse inodes feature is currently considered experimental. We warn
      at mount time from xfs_mount_validate_sb(). This function is part of the
      superblock verifier codepath, however, which means it could be invoked
      repeatedly on superblock reads or writes. This is currently only
      noticeable from userspace, where mkfs produces multiple warnings at
      format time.

      As mkfs warnings were not the intent of this change, relocate the mount
      time warning to xfs_fs_fill_super(), which is only invoked once and only
      in kernel space.

      Now that sb_uuid can be changed by the user, we cannot use this to
      validate the metadata blocks being recovered belong to this

      remain unchanged.

      There is a complication in this code - the superblock itself. We can
      not check the sb_meta_uuid unconditionally, as that may not be set
      on disk. Hence we must verify the superblock sb_uuid matches between
      the log record and the in-core superblock.

      xfs: set XFS_DA_OP_OKNOENT in xfs_attr_get

      It's entirely possible for userspace to ask for an xattr which
      does not exist.

      Normally, there is no problem whatsoever when we ask for such
      a thing, but when we look at an obfuscated metadump image
      on a debug kernel with selinux, we trip over this ASSERT in
      xfs_da3_path_shift():

              *result = -ENOENT;      /* we're out of our tree */
              ASSERT(args->op_flags & XFS_DA_OP_OKNOENT);

      It (more or less) only shows up in the above scenario, because
      xfs_metadump obfuscates attr names, but chooses names which
      keep the same hash value - and xfs_da3_node_lookup_int does:

              if (((retval == -ENOENT) || (retval == -ENOATTR)) &&
                  (blk->hashval == args->hashval)) {
                      error = xfs_da3_path_shift(state, &state->path, 1, 1,
                                                       &retval);

      IOWS, we only get down to the xfs_da3_path_shift() ASSERT
      if we are looking for an xattr which doesn't exist, but we
      find xattrs on disk which have the same hash, and so might be
      a hash collision, so we try the path shift.  When *that*
      fails to find what we're looking for, we hit the assert about
      XFS_DA_OP_OKNOENT.

      Simply setting XFS_DA_OP_OKNOENT in xfs_attr_get solves this
      rather corner-case problem with no ill side effects.  It's
      fine for an attr name lookup to fail.

      xfs: clean up root inode properly on mount failure

      The root inode is read as part of the xfs_mountfs() sequence and the
      reference is dropped in the event of failure after we grab the
      inode.  The reference drop doesn't necessarily free the inode,
      however. It marks it for reclaim and potentially kicks off the
      reclaim workqueue.  The workqueue is destroyed further up the error
      path, which means we are subject to crash if the workqueue job runs
      after this point or a memory leak which is identified if the
      xfs_inode_zone is destroyed (e.g., on module removal). Both of these
      outcomes are reproducible via manual instrumentation of a mount
      error after the root inode xfs_iget() call in xfs_mountfs().

      Update the xfs_mountfs() error path to cancel any potential reclaim
      work items and to run a synchronous inode reclaim if the root inode
      is marked for reclaim. This ensures that no jobs remain on the queue
      before it is destroyed and that the root inode is freed before the
      reclaim mechanism is torn down.

      xfs: checksum log record ext headers based on record size

      The first 4 bytes of every basic block in the physical log is stamped
      with the current lsn. To support this mechanism, the log record header
      (first block of each new log record) contains space for the original
      first byte of each log record block before it is replaced with the lsn.
      The log record header has space for 32k worth of blocks. The version 2
      log adds new extended record headers for each additional 32k worth of
      blocks beyond what is supported by the record header.

      The log record checksum incorporates the log record header, the extended
      headers and the record payload. xlog_cksum() checksums the extended
      headers based on log->l_iclog_heads, which specifies the number of
      extended headers in a log record based on the log buffer size mount
      option. The log buffer size is variable, however, and thus means the
      checksum can be calculated differently based on how a filesystem is
      mounted. This is problematic if a filesystem crashes and recovery occurs
      on a subsequent mount using a different log buffer size. For example,
      crash an active filesystem that is mounted with the default (32k)
      logbsize, attempt remount/recovery using '-o logbsize=64k' and the mount
      fails on or warns about log checksum failures.

      To avoid this problem, update xlog_cksum() to calculate the checksum
      based on the size of the log buffer according to the log record. The
      size is already included in the h_size field of the log record header
      and thus is available at log recovery time. Extended log record headers
      are also only written when the log record is large enough to require
      them. This makes checksum calculation of log records consistent with the
      extended record header mechanism as well as how on-disk records are
      checksummed with various log buffer size mount options.

      xfs: fix broken icreate log item cancellation

      Inode cluster buffers are invalidated and cancelled when inode chunks
      are freed to notify log recovery that previous logged updates to the
      metadata buffer should be skipped. This ensures that log recovery does
      not overwrite buffers that might have already been reused.

      On v4 filesystems, inode chunk allocation and inode updates are logged
      via the cluster buffers and thus cancellation is easily detected via
      buffer cancellation items. v5 filesystems use the new icreate
      transaction, which uses logical logging and ordered buffers to log a
      full inode chunk allocation at once. The resulting icreate item often
      spans multiple inode cluster buffers.

      Log recovery checks for cancelled buffers when processing icreate log
      items, but it has a couple problems. First, it uses the full length of
      the inode chunk rather than the cluster size. Second, it uses the length
      in FSB units rather than BB units. Either of these problems prevent
      icreate recovery from identifying cancelled buffers and thus inode
      initialization proceeds unconditionally.

      Update xlog_recover_do_icreate_pass2() to iterate the icreate range in
      cluster sized increments and check each increment for cancellation.
      Since icreate is currently only used for the minimum atomic inode chunk
      allocation, we expect that either all or none of the buffers will be
      cancelled. Cancel the icreate if at least one buffer is cancelled to
      avoid making a bad situation worse by initializing a partial inode
      chunk, but detect such anomalies and warn the user.

      xfs: don't leave EFIs on AIL on mount failure

      Log recovery occurs in two phases at mount time. In the first phase,
      EFIs and EFDs are processed and potentially cancelled out. EFIs without
      EFD objects are inserted into the AIL for processing and recovery in the
      second phase. xfs_mountfs() runs various other operations between the
      phases and is thus subject to failure. If failure occurs after the first
      phase but before the second, pending EFIs sit on the AIL, pin it and
      cause the mount to hang.

      Update the mount sequence to ensure that pending EFIs are cancelled in
      the event of failure. Add a recovery cancellation mechanism to iterate
      the AIL and cancel all EFI items when requested. Plumb cancellation
      support through the log mount finish helper and update xfs_mountfs() to
      invoke cancellation in the event of failure after recovery has started.

      xfs: use EFI refcount consistently in log recovery

      The EFI is initialized with a reference count of 2. One for the EFI to
      ensure the item makes it to the AIL and one for the subsequently created
      EFD to release the EFI once the EFD is committed. Log recovery uses the
      EFI in a similar manner, but implements a hack to remove both references
      in one call once the EFD is handled.

      Update log recovery to use EFI reference counting in a manner consistent
      with the log. When an EFI is encountered during recovery, an EFI item is
      allocated and inserted to the AIL directly. Since the EFI reference is
      typically dropped when the EFI is unpinned and this is analogous with
      AIL insertion, drop the EFI reference at this point.

      When a corresponding EFD is encountered in the log, this indicates that
      the extents were freed, no processing is required and the EFI can be
      dropped. Update xlog_recover_efd_pass2() to simply drop the EFD
      reference at this point rather than open code the AIL removal and EFI
      free.

      Remaining EFIs (i.e., with no corresponding EFD) are processed in
      xlog_recover_finish(). An EFD transaction is allocated and the extents
      are freed, which transfers ownership of the EFI reference to the EFD
      item in the log.

      xfs: ensure EFD trans aborts on log recovery extent free failure

      Log recovery attempts to free extents with leftover EFIs in the AIL
      after initial processing. If the extent free fails (e.g., due to
      unrelated fs corruption), the transaction is cancelled, though it
      might not be dirtied at the time. If this is the case, the EFD does
      not abort and thus does not release the EFI. This can lead to hangs
      as the EFI pins the AIL.

      Update xlog_recover_process_efi() to log the EFD in the transaction
      before xfs_free_extent() errors are handled to ensure the
      transaction is dirty, aborts the EFD and releases the EFI on error.
      Since this is a requirement for EFD processing (and consistent with
      xfs_bmap_finish()), update the EFD logging helper to do the extent
      free and unconditionally log the EFD. This encodes the required EFD
      logging behavior into the helper and reduces the likelihood of
      errors down the road.

      xfs: fix efi/efd error handling to avoid fs shutdown hangs

      Freeing an extent in XFS involves logging an EFI (extent free
      intention), freeing the actual extent, and logging an EFD (extent
      free done). The EFI object is created with a reference count of 2:
      one for the current transaction and one for the subsequently created
      EFD. Under normal circumstances, the first reference is dropped when
      the EFI is unpinned and the second reference is dropped when the EFD
      is committed to the on-disk log.

      In event of errors or filesystem shutdown, there are various
      potential cleanup scenarios depending on the state of the EFI/EFD.
      The cleanup scenarios are confusing and racy, as demonstrated by the
      following test sequence:

        # mount $dev $mnt
        # fsstress -d $mnt -n 99999 -p 16 -z -f fallocate=1 \
                -f punch=1 -f creat=1 -f unlink=1 &
        # sleep 5
        # killall -9 fsstress; wait
        # godown -f $mnt
        # umount

      ... in which the final umount can hang due to the AIL being pinned
      indefinitely by one or more EFI items. This can occur due to several
      conditions. For example, if the shutdown occurs after the EFI is
      committed to the on-disk log and the EFD committed to the CIL, but
      before the EFD committed to the log, the EFD iop_committed() abort
      handler does not drop its reference to the EFI. Alternatively,
      manual error injection in the xfs_bmap_finish() codepath shows that
      if an error occurs after the EFI transaction is committed but before
      the EFD is constructed and logged, the EFI is never released from
      the AIL.

      Update the EFI/EFD item handling code to use a more straightforward
      and reliable approach to error handling. If an error occurs after
      the EFI transaction is committed and before the EFD is constructed,
      release the EFI explicitly from xfs_bmap_finish(). If the EFI
      transaction is cancelled, release the EFI in the unlock handler.

      Once the EFD is constructed, it is responsible for releasing the EFI
      under any circumstances (including whether the EFI item aborts due
      to log I/O error). Update the EFD item handlers to release the EFI
      if the transaction is cancelled or aborts due to log I/O error.
      Finally, update xfs_bmap_finish() to log at least one EFD extent to
      the transaction before xfs_free_extent() errors are handled to
      ensure the transaction is dirty and EFD item error handling is
      triggered.

      xfs: disentagle EFI release from the extent count

      Release of the EFI either occurs based on the reference count or the
      extent count. The extent count used is either the count tracked in
      the EFI or EFD, depending on the particular situation. In either
      case, the count is initialized to the final value and thus always
      matches the current efi_next_extent value once the EFI is completely
      constructed.  For example, the EFI extent count is increased as the
      extents are logged in xfs_bmap_finish() and the full free list is
      always completely processed. Therefore, the count is guaranteed to
      be complete once the EFI transaction is committed. The EFD uses the
      efd_nextents counter to release the EFI. This counter is initialized
      to the count of the EFI when the EFD is created. Thus the EFD, as
      currently used, has no concept of partial EFI release based on
      extent count.

      Given that the EFI extent count is always released in whole, use of
      the extent count for reference counting is unnecessary. Remove this
      level of the API and release the EFI based on the core reference
      count. The efi_next_extent counter remains because it is still used
      to track the slot to log the next extent to free.

      blkcg: use CGROUP_WEIGHT_* scale for io.weight on the unified hierarchy

      cgroup is trying to make interface consistent across different
      controllers.  For weight based resource control, the knob should have
      the range [1, 10000] and default to 100.  This patch updates
      cfq-iosched so that the weight range conforms.  The internal
      calculations have enough range and the widening of the weight range
      shouldn't cause any problem.

      * blkcg_policy->cpd_bind_fn() is added.  If present, this is invoked
        when blkcg is attached to a hierarchy.

      * cfq_cpd_init() is updated to use the new default value on the
        unified hierarchy.

      * cfq_cpd_bind() callback is implemented to clear per-blkg configs and
        apply the default config matching the hierarchy type.

      * cfqd->root_group->[leaf_]weight initialization in cfq_init_queue()
        is moved into !CONFIG_CFQ_GROUP_IOSCHED block.  cfq_cpd_bind() is
        now responsible for initializing the initial weights when blkcg is
        enabled.

      blkcg: implement interface for the unified hierarchy

      blkcg interface grew to be the biggest of all controllers and
      unfortunately most inconsistent too.  The interface files are
      inconsistent with a number of cloes duplicates.  Some files have
      recursive variants while others don't.  There's distinction between
      normal and leaf weights which isn't intuitive and there are a lot of
      stat knobs which don't make much sense outside of debugging and expose
      too much implementation details to userland.

      In the unified hierarchy, everything is always hierarchical and
      internal nodes can't have tasks rendering the two structural issues
      twisting the current interface.  The interface has to be updated in a
      significant anyway and this is a good chance to revamp it as a whole.
      This patch implements blkcg interface for the unified hierarchy.

      * (from a previous patch) blkcg is identified by "io" instead of
        "blkio" on the unified hierarchy.  Given that the whole interface is
        updated anyway, the rename shouldn't carry noticeable conversion
        overhead.

      * The original interface consisted of 27 files is replaced with the
        following three files.

        blkio.stat      : per-blkcg stats
        blkio.weight    : per-cgroup and per-cgroup-queue weight settings
        blkio.max       : per-cgroup-queue bps and iops max limits

      Documentation/cgroups/unified-hierarchy.txt updated accordingly.

      v2: blkcg_policy->dfl_cftypes wasn't removed on
          blkcg_policy_unregister() corrupting the cftypes list.  Fixed.

      blkcg: move body parsing from blkg_conf_prep() to its callers

      Currently, blkg_conf_prep() expects input to be of the following form

       MAJ:MIN NUM

      and reads the NUM part into blkg_conf_ctx->v.  This is quite
      restrictive and gets in the way in implementing blkcg interface for
      the unified hierarchy.  This patch updates blkg_conf_prep() so that it
      expects

       MAJ:MIN BODY_STR

      where BODY_STR is an arbitrary string.  blkg_conf_ctx->v is replaced
      with ->body which is a char pointer pointing to the start of BODY_STR.
      Parsing of the body is moved to blkg_conf_prep()'s callers.

      To allow using, for example, strsep() on blkg_conf_ctx->val, it is a
      non-const pointer and to accommodate that const is dropped from @input
      too.

      blkcg: rename subsystem name from blkio to io

      blkio interface has become messy over time and is currently the
      largest.  In addition to the inconsistent naming scheme, it has
      multiple stat files which report more or less the same thing, a number
      of debug stat files which expose internal details which shouldn't have
      been part of the public interface in the first place, recursive and
      non-recursive stats and leaf and non-leaf knobs.

      Both recursive vs. non-recursive and leaf vs. non-leaf distinctions
      don't make any sense on the unified hierarchy as only leaf cgroups can
      contain processes.  cgroups is going through a major interface
      revision with the unified hierarchy involving significant fundamental
      usage changes and given that a significant portion of the interface
      doesn't make sense anymore, it's a good time to reorganize the
      interface.

      As the first step, this patch renames the external visible subsystem
      name from "blkio" to "io".  This is more concise, matches the other
      two major subsystem names, "cpu" and "memory", and better suited as
      blkcg will be involved in anything writeback related too whether an
      actual block device is involved or not.

      As the subsystem legacy_name is set to "blkio", the only userland
      visible change outside the unified hierarchy is that blkcg is reported
      as "io" instead of "blkio" in the subsystem initialized message during
      boot.  On the unified hierarchy, blkcg now appears as "io".

      "sectors_recursive" from stat_bytes.

      While this is a bit more code, it removes duplicate stat allocations
      and updates and ensures that the reported stats stay in tune with each

      blkcg: move io_service_bytes and io_serviced stats into blkcg_gq

      Currently, both cfq-iosched and blk-throttle keep track of
      io_service_bytes and io_serviced stats.  While keeping track of them
      separately may be useful during development, it doesn't make much
      sense otherwise.  Also, blk-throttle was counting bio's as IOs while
      cfq-iosched request's, which is more confusing than informative.

      This patch adds ->stat_bytes and ->stat_ios to blkg (blkcg_gq),
      removes the counterparts from cfq-iosched and blk-throttle and let
      them print from the common blkg counters.  The common counters are
      incremented during bio issue in blkcg_bio_issue_check().

      The outputs are still filtered by whether the policy has
      blkg_policy_data on a given blkg, so cfq's output won't show up if it
      has never been used for a given blkg.  The only times when the outputs
      would differ significantly are when policies are attached on the fly
      or elevators are switched back and forth.  Those are quite exceptional
      operations and I don't think they warrant keeping separate counters.

      v3: Update blkio-controller.txt accordingly.

      v2: Account IOs during bio issues instead of request completions so
          that bio-based drivers can be handled the same way.

      blkcg: make blkg_[rw]stat_recursive_sum() to be able to index into 
blkcg_gq

      Currently, blkg_[rw]stat_recursive_sum() assume that the target
      counter is located in pd (blkg_policy_data); however, some counters
      are planned to be moved to blkg (blkcg_gq).

      This patch updates blkg_[rw]stat_recursive_sum() to take blkg and
      blkg_policy pointers instead of pd.  If policy is NULL, it indexes
      into blkg.  If non-NULL, into the blkg's pd of the policy.

      The existing usages are updated to maintain the current behaviors.

      blkcg: make blkcg_[rw]stat per-cpu

      blkcg_[rw]stat are used as stat counters for blkcg policies.  It isn't
      per-cpu by itself and blk-throttle makes it per-cpu by wrapping around
      it.  This patch makes blkcg_[rw]stat per-cpu and drop the ad-hoc
      per-cpu wrapping in blk-throttle.

      * blkg_[rw]stat->cnt is replaced with cpu_cnt which is struct
        percpu_counter.  This makes syncp unnecessary as remote accesses are
        handled by percpu_counter itself.

      * blkg_[rw]stat_init() can now fail due to percpu allocation failure
        and thus are updated to return int.

      * percpu_counters need explicit freeing.  blkg_[rw]stat_exit() added.

      * As blkg_rwstat->cpu_cnt[] can't be read directly anymore, reading
        and summing results are stored in ->aux_cnt[] instead.

      * Custom per-cpu stat implementation in blk-throttle is removed.

      This makes all blkcg stat counters per-cpu without complicating policy
      implmentations.

      blkcg: add blkg_[rw]stat->aux_cnt and replace cfq_group->dead_stats with 
it

      cgroup stats are local to each cgroup and doesn't propagate to
      ancestors by default.  When recursive stats are necessary, the sum is
      calculated over all the descendants.  This initially was for backward
      compatibility to support both group-local and recursive stats but this
      mode of operation makes general sense as stat update is much hotter
      thafn reporting those stats.

      This however ends up losing recursive stats when a child is removed.
      To work around this, cfq-iosched adds its stats to its parent
      cfq_group->dead_stats which is summed up together when calculating
      recursive stats.

      It's planned that the core stats will be moved to blkcg_gq, so we want
      to move the mechanism for keeping track of the stats of dead children
      from cfq to blkcg core.  This patch adds blkg_[rw]stat->aux_cnt which
      are atomic64_t's keeping track of auxiliary counts which are excluded
      when reading local counts but included for recursive.

      blkg_[rw]stat_merge() which were used by cfq to implement dead_stats
      are replaced by blkg_[rw]stat_add_aux(), and cfq now forwards stats of
      a dead cgroup to the aux counts of parent->stats instead of separate
      ->dead_stats.

      This will also help making blkg_[rw]stats per-cpu.

      blkcg: consolidate blkg creation in blkcg_bio_issue_check()

      blkg (blkcg_gq) currently is created by blkcg policies invoking
      blkg_lookup_create() which ends up repeating about the same code in
      different policies.  Theoretically, this can avoid the overhead of
      looking and/or creating blkg's if blkcg is enabled but no policy is in
      use; however, the cost of blkg lookup / creation is very low
      especially if only the root blkcg is in use which is highly likely if
      no blkcg policy is in active use - it boils down to a single very
      predictable conditional and surrounding RCU protection.

      This patch consolidates blkg creation to a new function
      blkcg_bio_issue_check() which is called during bio issue from
      generic_make_request_checks().  blkcg_bio_issue_check() is now the
      only function which tries to create missing blkg's.  The subsequent
      policy and request_list operations just perform blkg_lookup() and if
      missing falls back to the root.

      * blk_get_rl() no longer tries to create blkg.  It uses blkg_lookup()
        instead of blkg_lookup_create().

      * blk_throtl_bio() is now called from blkcg_bio_issue_check() with rcu
        read locked and blkg already looked up.  Both throtl_lookup_tg() and
        throtl_lookup_create_tg() are dropped.

      * cfq is similarly updated.  cfq_lookup_create_cfqg() is replaced with
        cfq_lookup_cfqg()which uses blkg_lookup().

      This consolidates blkg handling and avoids unnecessary blkg creation
      retries under memory pressure.  In addition, this provides a common
      bio entry point into blkcg where things like common accounting can be
      performed.

      v2: Build fixes for !CONFIG_CFQ_GROUP_IOSCHED and
          !CONFIG_BLK_DEV_THROTTLING.

      blk-throttle: improve queue bypass handling

      If a queue is bypassing, all blkcg policies should become noops but
      blk-throttle wasn't.  It only became noop if the queue was dying.
      While this wouldn't lead to an oops as falling back to the root blkg
      is safe in this case, this can be a bit surprising - a bypassing queue
      could still be applying throttle limits.

      Fix it by removing blk_queue_dying() test in throtl_lookup_create_tg()
      and testing blk_queue_bypass() in blk_throtl_bio() and bypassing
      before doing anything else.

      blkg_lookup() checks whether the target queue is bypassing and, if

      blkg_lookup() and the fast path part of __blkg_lookup().  The radix
      tree lookup and hint update are now in blkg_lookup_slowpath().

      This will help consolidating blkg handling by easing moving root blkcg

      blkcg: replace blkcg_policy->cpd_size with ->cpd_alloc/free_fn() methods

      Each active policy has a cpd (blkcg_policy_data) on each blkcg.  The
      cpd's were allocated by blkcg core and each policy could request to
      allocate extra space at the end by setting blkcg_policy->cpd_size
      larger than the size of cpd.

      This is a bit unusual but blkg (blkcg_gq) policy data used to be
      handled this way too so it made sense to be consistent; however, blkg
      policy data switched to alloc/free callbacks.

      This patch makes similar changes to cpd handling.
      blkcg_policy->cpd_alloc/free_fn() are added to replace ->cpd_size.  As
      cpd allocation is now done from policy side, it can simply allocate a
      larger area which embeds cpd at the beginning.

      As ->cpd_alloc_fn() may be able to perform all necessary
      initializations, this patch makes ->cpd_init_fn() optional.

      blkcg: make blkcg_policy methods take a pointer to blkcg_policy_data

      The newly added ->pd_alloc_fn() and ->pd_free_fn() deal with pd
      (blkg_policy_data) while the older ones use blkg (blkcg_gq).  As using
      blkg doesn't make sense for ->pd_alloc_fn() and after allocation pd
      can always be mapped to blkg and given that these are policy-specific
      methods, it makes sense to converge on pd.

      This patch makes all methods deal with pd instead of blkg.  Most
      conversions are trivial.  In blk-cgroup.c, a couple method invocation
      sites now test whether pd exists instead of policy state for
      consistency.  This shouldn't cause any behavioral differences.

      * ->pd_alloc_fn()

      * ->pd_init_fn()

        Initializations which require the knowledge of where the pd is
        attached.

      * ->pd_free_fn()

        The counter part of pd_alloc_fn().  Static de-init and freeing.

      This leaves ->pd_exit_fn() without any users.  Removed.

      While at it, collapse an one liner function throtl_pd_exit(), which
      has only one user, into its user.

      blk-throttle: remove asynchrnous percpu stats allocation mechanism

      Because percpu allocator couldn't do non-blocking allocations,
      blk-throttle was forced to implement an ad-hoc asynchronous allocation
      mechanism for its percpu stats for cases where blkg's (blkcg_gq's) are
      allocated from an IO path without sleepable context.

      Now that percpu allocator can handle gfp_mask and blkg_policy_data
      alloc / free are handled by policy methods, the ad-hoc asynchronous
      allocation mechanism can be replaced with direct allocation from
      tg_stats_alloc_fn().  Rit it out.

      This ensures that an active throtl_grp always has valid non-NULL
      ->stats_cpu.  Remove checks on it.

      blkcg: replace blkcg_policy->pd_size with ->pd_alloc/free_fn() methods

      A blkg (blkcg_gq) represents the relationship between a cgroup and
      request_queue.  Each active policy has a pd (blkg_policy_data) on each
      blkg.  The pd's were allocated by blkcg core and each policy could
      request to allocate extra space at the end by setting
      blkcg_policy->pd_size larger than the size of pd.

      This is a bit unusual but was done this way mostly to simplify error
      handling and all the existing use cases could be handled this way;
      however, this is becoming too restrictive now that percpu memory can
      be allocated without blocking.

      This introduces two new mandatory blkcg_policy methods - pd_alloc_fn()
      and pd_free_fn() - which are used to allocate and release pd for a
      given policy.  As pd allocation is now done from policy side, it can
      simply allocate a larger area which embeds pd at the beginning.  This
      change makes ->pd_size pointless.  Removed.

      blkcg: restructure blkg_policy_data allocation in blkcg_activate_policy()

      When a policy gets activated, it needs to allocate and install its
      policy data on all existing blkg's (blkcg_gq's).  Because blkg
      iteration is protected by a spinlock, it currently counts the total
      number of blkg's in the system, allocates the matching number of
      policy data on a list and installs them during a single iteration.

      This can be simplified by using speculative GFP_NOWAIT allocations
      while iterating and falling back to a preallocated policy data on
      failure.  If the preallocated one has already been consumed, it
      releases the lock, preallocate with GFP_KERNEL and then restarts the
      iteration.  This can be a bit more expensive than before but policy
      activation is a very cold path and shouldn't matter.

      blkcg: remove unnecessary blkcg_root handling from css_alloc/free paths

      bypasses policy data and blkcg freeing for blkcg_root.  There's no
      reason to to treat policy data any differently for blkcg_root.  If the
      root css gets allocated after policies are registered, policy
      registration path will add policy data; otherwise, the alloc path
      will.  The free path isn't never invoked for root csses.

      blkcg: use blkg_free() in blkcg_init_queue() failure path

      When blkcg_init_queue() fails midway after creating a new blkg, it
      performs kfree() directly; however, this doesn't free the policy data
      areas.  Make it use blkg_free() instead.  In turn, blkg_free() is
      updated to handle root request_list special case.

      While this fixes a possible memory leak, it's on an unlikely failure
      path of an already cold path and the size leaked per occurrence is
      miniscule too.  I don't think it needs to be tagged for -stable.

      cfq-iosched: charge async IOs to the appropriate blkcg's instead of the 
root

      Up until now, all async IOs were queued to async queues which are
      shared across the whole request_queue, which means that blkcg resource
      control is completely void on async IOs including all writeback IOs.
      It was done this way because writeback didn't support writeback and
      there was no way of telling which writeback IO belonged to which
      cgroup; however, writeback recently became cgroup aware and writeback
      bio's are sent down properly tagged with the blkcg's to charge them
      against.

      This patch makes async cfq_queues per-cfq_cgroup instead of
      per-cfq_data so that each async IO is charged to the blkcg that it was
      tagged for instead of unconditionally attributing it to root.

      * cfq_data->async_cfqq and ->async_idle_cfqq are moved to cfq_group
        and alloc / destroy paths are updated accordingly.

      * cfq_link_cfqq_cfqg() no longer overrides @cfqg to root for async
        queues.

      * check_blkcg_changed() now also invalidates async queues as they no
        longer stay the same across cgroups.

      After this patch, cfq's proportional IO control through blkio.weight
      works correctly when cgroup writeback is in use.

      cfq-iosched: fold cfq_find_alloc_queue() into cfq_get_queue()

      cfq_find_alloc_queue() checks whether a queue actually needs to be
      allocated, which is unnecessary as its sole caller, cfq_get_queue(),
      only calls it if so.  Also, the oom queue fallback logic is scattered
      between cfq_get_queue() and cfq_find_alloc_queue().  There really
      isn't much going on in the latter and things can be made simpler by
      folding it into cfq_get_queue().

      This patch collapses cfq_find_alloc_queue() into cfq_get_queue().  The
      change is fairly straight-forward with one exception - async_cfqq is
      now initialized to NULL and the "!is_sync" test in the last if
      conditional is replaced with "async_cfqq" test.  This is because gcc
      (5.1.1) gets confused for some reason and warns that async_cfqq may be
      used uninitialized otherwise.  Oh well, the code isn't necessarily
      worse this way.

      This patch doesn't cause any functional difference.

      This is necessary for making async cfq_cgroups per-cfq_group instead
      of per-cfq_data.  While this change makes cfq_get_queue() perform RCU
      locking and look up cfq_group even when it reuses async queue, the
      extra overhead is extremely unlikely to be noticeable given that this
      is already sitting behind cic->cfqq[] cache and the overall cost of

      cfq-iosched: remove @gfp_mask from cfq_find_alloc_queue()

      Even when allocations fail, cfq_find_alloc_queue() always returns a
      valid cfq_queue by falling back to the oom cfq_queue.  As such, there
      isn't much point in taking @gfp_mask and trying "harder" if __GFP_WAIT
      is set.  GFP_NOWAIT allocations don't fail often and even when they do
      the degraded behavior is acceptable and temporary.

      After all, the only reason get_request(), which ultimately determines
      the gfp_mask, cares about __GFP_WAIT is to guarantee request
      allocation, assuming IO forward progress, for callers which are
      willing to wait.  There's no reason for cfq_find_alloc_queue() to
      behave differently on __GFP_WAIT when it already has a fallback
      mechanism.

      Remove @gfp_mask from cfq_find_alloc_queue() and propagate the changes
      to its callers.  This simplifies the function quite a bit and will
      help making async queues per-cfq_group.

      blkcg, cfq-iosched: use GFP_NOWAIT instead of GFP_ATOMIC for non-critical 
allocations

      blkcg performs several allocations to track IOs per cgroup and enforce
      resource control.  Most of these allocations are performed lazily on
      demand in the IO path and thus can't involve reclaim path.  Currently,
      these allocations use GFP_ATOMIC; however, blkcg can gracefully deal
      with occassional failures of these allocations by punting IOs to the
      root cgroup and there's no reason to reach into the emergency reserve.

      This patch replaces GFP_ATOMIC with GFP_NOWAIT for the following
      allocations.

      * bdi_writeback_congested and blkcg_gq allocations in blkg_create().

      * radix tree node allocations for blkcg->blkg_tree.

      * cfq_queue allocation on ioprio changes.

      cfq-iosched: fix oom cfq_queue ref leak in cfq_set_request()

      If the cfq_queue cached in cfq_io_cq is the oom one, cfq_set_request()
      replaces it by invoking cfq_get_queue() again without putting the oom
      queue leaking the reference it was holding.  While oom queues are not
      released through reference counting, they're still reference counted
      and this can theoretically lead to the reference count overflowing and
      incorrectly invoke the usual release path on it.

      cfq-iosched: fix async oom queue handling

      Async cfqq's (cfq_queue's) are shared across cfq_data.  When
      cfq_get_queue() obtains a new queue from cfq_find_alloc_queue(), it
      stashes the pointer in cfq_data and reuses it from then on; however,
      the function doesn't consider that cfq_find_alloc_queue() may return
      the oom_cfqq under memory pressure and installs the returned queue
      unconditionally.

      If the oom_cfqq is installed as an async cfqq, cfq_set_request() will
      continue calling cfq_get_queue() hoping to replace it with a proper
      queue; however, cfq_get_queue() will keep returning the cached queue
      for the slot - the oom_cfqq.

      Fix it by skipping caching if the queue is the oom one.

      cfq-iosched: simplify control flow in cfq_get_queue()

      cfq_get_queue()'s control flow looks like the following.

        async_cfqq = NULL;
        cfqq = NULL;

        if (!is_sync) {
                ...
                async_cfqq = ...;
                cfqq = *async_cfqq;
        }

        if (!cfqq)
                cfqq = ...;

        if (!is_sync && !(*async_cfqq))
                ...;

      The only thing the local variable init, the second if, and the
      async_cfqq test in the third if achieves is to skip cfqq creation and
      installation if *async_cfqq was already non-NULL.  This is needlessly
      complicated with different tests examining the same condition.
      Simplify it to the following.

        if (!is_sync) {

      * writeback_queue
      * writeback_exec

      * balance_dirty_pages
      * writeback_sb_inodes_requeue
      * writeback_single_inode[_start]

      Note that writeback_bdi_register is separated out from writeback_class
      as reporting cgroup doesn't make sense to it.  Tracepoints which take
      bdi are updated to take bdi_writeback instead.

      wb_writeback_work->single_wait/done are used for the wait mechanism
      for synchronous wb_work (wb_writeback_work) items which are issued

      writeback: bdi_for_each_wb() iteration is memcg ID based not blkcg

      wb's (bdi_writeback's) are currently keyed by memcg ID; however, in an
      earlier implementation, wb's were keyed by blkcg ID.
      bdi_for_each_wb() walks bdi->cgwb_tree in the ascending ID order and
      allows iterations to start from an arbitrary ID which is used to
      interrupt and resume iterations.

      Unfortunately, while changing wb to be keyed by memcg ID instead of
      blkcg, bdi_for_each_wb() was missed and is still assuming that wb's
      are keyed by blkcg ID.  This doesn't affect iterations which don't get
      interrupted but bdi_split_work_to_wbs() makes use of iteration
      resuming on allocation failures and thus may incorrectly skip or
      repeat wb's.

      Fix it by changing bdi_for_each_wb() to take memcg IDs instead of
      blkcg IDs and updating bdi_split_work_to_wbs() accordingly.

      Using usbmon, it turns out the interrupt URBs were streaming with
      callback errors of -71 for some reason.  The hid-core.c::hid_io_error was
      supposed to retry and then reset, but the reset wasn't really happening.

      The check for HID_NO_BANDWIDTH was inverted.  Fix was simple.

      This patch adds the ability to connect to the vxlan NDOs and configure
      the UDP port associated with it in the HW.

      The device would now be capable of performing RSS according to the
      inner headers of the vxlan packets.

      dm stats: report precise_timestamps and histogram in @stats_list output

      If the user selected the precise_timestamps or histogram options, report
      it in the @stats_list message output.

      If the user didn't select these options, no extra tokens are reported,
      thus it is backward compatible with old software that doesn't know about
      precise timestamps and histogram.

      D in DSA patches

      The D in DSA is distributed, meaning multiple switches can be
      connected together. Currently no mainline system does this, and so the
      code is broken. This patchset contains two fixes, and a small helper.

      With three of more switches, the current device tree binding is not
      sufficient to express the routing between the switches. The first
      patch extends the binding, in a backwards compatible way, to allow a
      link between a switch to describe all the switches accessible over the
      link, not just the direct neighbor.

      The third patch fixes the port configuration on newer devices for
      links connecting switches.

      dsa: mv88e6xxx: Set DSA mode based on chip abilities

      Older devices only support a single DSA frame format, where as newer
      devices have two. Take this into account when configuring a DSA port.
      The port needs to be in plain old DSA mode, since this is a DSA link,
      where as the newer format can be used for the CPU port.

      net: dsa: Allow multi hop routes to be expressed

      With more than two switches in a hierarchy, it becomes necessary to
      describe multi-hop routes between switches. The current binding does
      not allow this, although the older platform_data did. Extend the link
      property to be a list rather than a single phandle to a remote switch.
      It is then possible to express that a port should be used to reach
      more than one switch and the switch maybe more than one hop away.

      e1000e: Modify Tx/Rx configurations to avoid null pointer dereferences in

      When e1000e_setup_rx_resources is failed in e1000_open,
      e1000e_free_tx_resources in "err_setup_rx" segment is executed.
      "writel(0, tx_ring->head)" statement in e1000_clean_tx_ring
      in e1000e_free_tx_resources will cause a null poonter dereference(crash),
      because "tx_ring->head" is only assigned in e1000_configure_tx
      in e1000_configure, but it is after e1000e_setup_rx_resources.

      This patch moves head/tail register writing to e1000_configure_tx/rx,
      which can fix this problem. It is inspired by igb_configure_tx_ring
      in the igb driver.

      igb: Teardown SR-IOV before unregister_netdev()

      When the .remove() callback for a PF is called, SR-IOV support for the
      device is disabled, which requires unbinding and removing the VFs.
      The VFs may be in-use either by the host kernel or userspace, such as
      assigned to a VM through vfio-pci.  In this latter case, the VFs may
      be removed either by shutting down the VM or hot-unplugging the
      devices from the VM.  Unfortunately in the case of a Windows 2012 R2
      guest, hot-unplug is broken due to the ordering of the PF driver
      teardown.  Disabling SR-IOV prior to unregister_netdev() avoids this
      issue.

          ->igb_pci_enable_sriov

      Doing the SR-IOV re-init is not necessary during probing since we're
      starting from scratch. Here we can call igb_enable_sriov() right away.

      Running igb_sriov_reinit() during igb_probe() also seems to cause

      igb: Fix oops caused by missing queue pairing

      When initializing igb driver (e.g. 82576, I350), IGB_FLAG_QUEUE_PAIRS is
      set if adapter->rss_queues exceeds half of max_rss_queues in
      igb_init_queue_configuration().
      On the other hand, IGB_FLAG_QUEUE_PAIRS is not set even if the number of
      queues exceeds half of max_combined in igb_set_channels() when changing
      the number of queues by "ethtool -L".
      In this case, if numvecs is larger than MAX_MSIX_ENTRIES (10), the size
      of adapter->msix_entries[], an overflow can occur in
      igb_set_interrupt_capability(), which in turn leads to an oops.

      Fix this problem as follows:
       - When changing the number of queues by "ethtool -L", set
         IGB_FLAG_QUEUE_PAIRS in the same way as initializing igb driver.
       - When increasing the size of q_vector, reallocate it appropriately.
         (With IGB_FLAG_QUEUE_PAIRS set, the size of q_vector gets larger.)

      Another possible way to fix this problem is to cap the queues at its
      initial number, which is the number of the initial online cpus. But this
      is not the optimal way because we cannot increase queues when another
      cpu becomes online.

      Note that before commit cd14ef54d25b ("igb: Change to use statically
      allocated array for MSIx entries"), this problem did not cause oops
      but just made the number of queues become 1 because of entering msi_only
      mode in igb_set_interrupt_capability().

      block: bump BLK_DEF_MAX_SECTORS to 2560

      A value of 2560 (1280k) will accommodate a 10-data-disk stripe
      write with chunk size 128k.  In the testing I've done using
      iozone, fio, and aio-stress across a number of different storage
      devices, a value of 1280 does not show a big performance
      difference from 512, but will hopefully help software RAID
      setups using SATA disks, as reported by Christoph.

      NOTE: drivers/block/aoe/aoeblk.c sets its own max_hw_sectors_kb to
      BLK_DEF_MAX_SECTORS.  So, this patch essentially changes aeoblk to
      Use a larger maximum sector size, and I did not test this.

      Revert "block: remove artifical max_hw_sectors cap"

      This reverts commit 34b48db66e08ca1c1bc07cf305d672ac940268dc.
      That commit caused performance regressions for streaming I/O
      workloads on a number of different storage devices, from
      SATA disks to external RAID arrays.  It also managed to
      trip up some buggy firmware in at least one drive, causing
      data corruption.

      The next patch will bump the default max_sectors_kb value to
      1280, which will accommodate a 10-data-disk stripe write
      with chunk size 128k.  In the testing I've done using iozone,
      fio, and aio-stress, a value of 1280 does not show a big
      performance difference from 512.  This will hopefully still
      help the software RAID setup that Christoph saw the original
      performance gains with while still not regressing other
      storage configurations.

      ARM64: dts: vexpress: Use assigned-clock-parents for sp810

      The sp810 clk driver is calling the clk consumer APIs from
      clk_prepare ops to change the parent to a 1 MHz fixed rate clock
      for each of the clocks that the driver provides. Use
      assigned-clock-parents for this instead of doing it in the driver
      to avoid using the consumer API in provider code. This also
      allows us to remove the usage of clk provider APIs that take a

      The i.MX SoC changes for 4.3:
       - Add i.MX6 Ultralite SoC support, which is the newest addition to
         i.MX6 family.  It integrates a single Cortex-A7 core and a power
         management module that reduces the complexity of external power
         supply and simplifies power sequencing.
       - Change SNVS RTC driver to use syscon interface for register access,
         and add SNVS power key driver support.
       - Add a second clock for mxc rtc driver, and support device tree probe
         for the driver.
       - Add FEC MAC reference clock and phy fixup initialization for i.MX6UL
         platform.

      net: Convert drivers to IFF_NO_QUEUE and cleanup afterwards

      This series converts in-tree users away from the old and deprecated
      'tx_queue_len = 0' idiom, adds a warning to notify out-of-tree driver
      maintainers that there is need for action on their behalf and finally 
drops any
      workarounds in scheduling algorithm implementations.

      net: sched: drop all special handling of tx_queue_len == 0

      Those were all workarounds for the formerly double meaning of
      tx_queue_len, which broke scheduling algorithms if untreated.

      Now that all in-tree drivers have been converted away from setting
      tx_queue_len = 0, it should be safe to drop these workarounds for
      categorically broken setups.

      net: warn if drivers set tx_queue_len = 0

      Due to the introduction of IFF_NO_QUEUE, there is a better way for
      drivers to indicate that no qdisc should be attached by default. Though,
      the old convention can't be dropped since ignoring that setting would
      break drivers still using it. Instead, add a warning so out-of-tree
      driver maintainers get a chance to adjust their code before we finally
      get rid of any special handling of tx_queue_len == 0.

      NVMe: Add nvme subsystem reset IOCTL

      Controllers can perform optional subsystem resets as introduced in NVMe
      1.1. This patch adds an IOCTL to trigger the subsystem reset by writing
      "NVMe" to the NSSR register.

      NVMe: Add nvme subsystem reset support

      Controllers part of an NVMe subsystem may be reset by any other controller
      in the subsystem. If the device is capable of subsystem resets, this
      patch adds detection for such events and performs appropriate controller
      initialization upon subsystem reset detection.

      The register bit is a RW1C type, so the driver needs to write a 1 to the
      status bit to clear the subsystem reset occured bit during initialization.

      inode: don't softlockup when evicting inodes

      On a box with a lot of ram (148gb) I can make the box softlockup after 
running
      an fs_mark job that creates hundreds of millions of empty files.  This is
      because we never generate enough memory pressure to keep the number of 
inodes on
      our unused list low, so when we go to unmount we have to evict ~100 
million
      inodes.  This makes one processor a very unhappy person, so add a 
cond_resched()
      in dispose_list() and if we need a resched when processing the s_inodes 
list do
      that and run dispose_list() on what we've currently culled.  Thanks,

      USB: symbolserial: Correct transferred data size

      The scanner (here DS3508) always returns 64 bytes per urb buffer. The 
first
      byte indicates the data length used in the current buffer. There even was
      a comment describing this. But the comment also said that we'll send
      everything in the buffer to the tty layer. That means sending the actual
      barcode data and lots of trailing zeroes. This patch lets the driver only
      send the real data.

      dmaengine: jz4780: Fall back on smaller transfer sizes where necessary

      For some reason the controller does not support 8 byte transfers (but
      does support all other powers of 2 up to 128). In this case fall back
      to 4 bytes. In addition, fall back to 128 bytes when any larger power
      of 2 would be possible within the alignment constraints, as this is
      the maximum supported.

      It makes no sense to outright reject 8 or >128 bytes just because the
      alignment constraints make those the maximum possible size given the
      parameters for the transaction. For instance, this can result in a DMA
      from/to an 8 byte aligned address failing.

      It is perfectly safe to fall back to smaller transfer sizes, the only
      consequence is reduced transfer efficiency, which is far better than
      not allowing the transfer at all.

      Convert to managed resources"). Before this commit, PM cleanup was
      performed after the component was unregistered. But returning

      If DMA interrupt comes and is latched by IRQ controller during the

      SCSI: Fix NULL pointer dereference in runtime PM

      The routines in scsi_rpm.c assume that if a runtime-PM callback is
      invoked for a SCSI device, it can only mean that the device's driver
      has asked the block layer to handle the runtime power management (by
      calling blk_pm_runtime_init(), which among other things sets q->dev).

      However, this assumption turns out to be wrong for things like the ses
      driver.  Normally ses devices are not allowed to do runtime PM, but
      userspace can override this setting.  If this happens, the kernel gets
      a NULL pointer dereference when blk_post_runtime_resume() tries to use
      the uninitialized q->dev pointer.

      This patch fixes the problem by calling the block layer's runtime-PM
      routines only if the device's driver really does have a runtime-PM
      callback routine.  Since ses doesn't define any such callbacks, the
      crash won't occur.

      This fixes Bugzilla #101371.

      fnic: Use the local variable instead of I/O flag to acquire io_req_lock 
in fnic_queuecommand() to avoid deadloack

      We added changes in fnic driver patch 1.6.0.16 to acquire
      io_req_lock in fnic_queuecommand() before issuing I/O so that io 
completion
      is serialized. But when releasing the lock we check for the I/O flag and
      this could be modified if IO abort occurs before I/O completion. In this 
case
      we wont release the lock and causes deadlock in some scenerios. Using the
      local variable to check the IO lock status will resolve the problem.

      ARM: 8415/1: early fixmap support for earlycon

      Add early fixmap support, initially to support permanent, fixed
      mapping support for early console. A temporary, early pte is
      created which is migrated to a permanent mapping in paging_init.
      This is also needed since the attributes may change as the memory
      types are initialized. The 3MiB range of fixmap spans two pte
      tables, but currently only one pte is created for early fixmap
      support.

        while DRM is setting a mode, which could race with a mode being set.
      * Hotplug will always re-enable the phy whenever it detects an active
        hotplug signal, even if DRM has disabled the output.

      Resolve all of these by introducing a mutex to prevent races, and a
      state-tracking bool so we know whether DRM wishes the output to be
      enabled.  We choose to use our own mutex rather than ->struct_mutex
      so that we can still process interrupts in a timely fashion.

      drm: bridge/dw_hdmi: rename dw_hdmi_phy_enable_power()

      dw_hdmi_phy_enable_power() is not about enabling and disabling power.
      It is about allowing or preventing power-down mode being entered - the
      register is documented as "Power-down enable (active low 0b)."

      This can be seen as the bit has no effect when the HDMI phy is
      operational on iMX6 hardware.

      Rename the function to dw_hdmi_phy_enable_powerdown() to reflect the
      documentation, make it take a bool for the 'enable' argument, and invert
      the value to be written.

      drm: bridge/dw_hdmi: avoid enabling interface in mode_set

      On a mode set, DRM makes the following sequence of calls:
      * for_each_encoder
      *   bridge        mode_fixup
      *   encoder       mode_fixup
      * crtc            mode_fixup
      * for_each_encoder
      *   bridge        disable
      *   encoder       prepare
      *   bridge        post_disable
      * disable unused encoders
      * crtc            prepare
      * crtc            mode_set
      * for_each_encoder
      *   encoder       mode_set
      *   bridge        mode_set
      * crtc            commit
      * for_each_encoder
      *   bridge        pre_enable
      *   encoder       commit
      *   bridge        enable

      dw_hdmi enables the HDMI output in both the bridge mode_set() and also
      the bridge enable() step.  This is duplicated work - we can avoid the
      setup in mode_set() and just do it in the enable() stage.  This
      simplifies the code a little.

      drm: bridge/dw_hdmi: clean up HDMI vs DVI mode handling

      The FSL kernel detects the HDMI vendor id, and uses this to set
      hdmi->edid_cfg.hdmi_cap, which is then used to set mdvi appropriately,
      rather than detecting whether we are outputting a CEA mode.  Update
      the dw_hdmi code to use this logic, but lets eliminate the mdvi
      variable, prefering the more verbose "hdmi->sink_is_hdmi" instead.

      Use the generic drm_detect_hdmi_monitor() to detect a HDMI sink.

      drm: bridge/dw_hdmi: remove pixel repetition setting for all VICs

      dw_hdmi sets a pixel repetition factor of 1 for VICs 10-15, 25-30 and
      35-38.  However, DRM uses their native resolutions in its timing
      information.  For example, VIC 14 can be 1440x480 with no repetition,
      or 720x480 with one pixel repetition.  As DRM uses 1440 pixels per line
      for this video mode, we need no pixel repetition.

      In any case, pixel repetition appears broken in dw_hdmi.

      drm: bridge/dw_hdmi: introduce interfaces to enable and disable audio

      iMX6 devices suffer from an errata (ERR005174) where the audio FIFO can
      be emptied while it is partially full, resulting in misalignment of the
      audio samples.

      To prevent this, the errata workaround recommends writing N as zero
      until the audio FIFO has been loaded by DMA.  Writing N=0 prevents the
      HDMI bridge from reading from the audio FIFO, effectively disabling
      audio.

      This means we need to provide the audio driver with a pair of functions
      to enable/disable audio.  These are dw_hdmi_audio_enable() and
      dw_hdmi_audio_disable().

      A spinlock is introduced to ensure that setting the CTS/N values can't
      race, ensuring that the audio driver calling the enable/disable
      functions (which are called in an atomic context) can't race with a
      modeset.

      cxl: Add alternate MMIO error handling

      userspace programs using cxl currently have to use two strategies for
      dealing with MMIO errors simultaneously. They have to check every read
      for a return of all Fs in case the adapter has gone away and the kernel
      has not yet noticed, and they have to deal with SIGBUS in case the
      kernel has already noticed, invalidated the mapping and marked the
      context as failed.

      In order to simplify things, this patch adds an alternative approach
      where the kernel will return a page filled with Fs instead of delivering
      a SIGBUS. This allows userspace to only need to deal with one of these
      two error paths, and is intended for use in libraries that use cxl
      transparently and may not be able to safely install a signal handler.

      This approach will only work if certain constraints are met. Namely, if
      the application is both reading and writing to an address in the problem
      state area it cannot assume that a non-FF read is OK, as it may just be
      reading out a value it has previously written. Further - since only one
      page is used per context a write to a given offset would be visible when
      reading the same offset from a different page in the mapping (this only
      applies within a single context, not between contexts).

      An application could deal with this by e.g. making sure it also reads
      from a read-only offset after any reads to a read/write offset.

      Due to these constraints, this functionality must be explicitly
      requested by userspace when starting the context by passing in the
      CXL_START_WORK_ERR_FF flag.

      powerpc/pseries: enable RTC class support

      A working rtc kernel driver is needed so that hwclock can synchronize
      system clock to rtc during shutdown/boot. We already have a powernv
      platform rtc driver located at drivers/rtc/rtc-opal.c. However it depends
      on CONFIG_RTC_CLASS which is disabled by default. Hence the driver isn't
      enabled and not compiled for the powernv kernel.

      We fix this by enabling rtc class support in pseries defconfig which
      enables this driver and compiles it into the pseries kernel. In case
      CONFIG_PPC_POWERNV is not enabled we fallback to 'Generic RTC support'
      driver which emulates the legacy 'PC RTC driver'.

      powerpc/numa: initialize distance lookup table from drconf path

      In some situations, a NUMA guest that supports
      ibm,dynamic-memory-reconfiguration node will end up having flat NUMA
      distances between nodes. This is because of two problems in the
      current code.

      1) Different representations of associativity lists.

         There is an assumption about the associativity list in
         initialize_distance_lookup_table(). Associativity list has two forms:

         a) [cpu,memory]@x/ibm,associativity has following
            format:
                 <N> <N integers>

         b) ibm,dynamic-reconfiguration-memory/ibm,associativity-lookup-arrays

                 <M> <N> <M associativity lists each having N integers>
                 M = the number of associativity lists
                 N = the number of entries per associativity list

         Fix initialize_distance_lookup_table() so that it does not assume
         "case a". And update the caller to skip the length field before
         sending the associativity list.

      2) Distance table not getting updated from drconf path.

         Node distance table will not get initialized in certain cases as
         ibm,dynamic-reconfiguration-memory path does not initialize the
         lookup table.

         Call initialize_distance_lookup_table() from drconf path with
         appropriate associativity list.

        1) call ppc_md.dma_get_required_mask, if it exists. On powernv, that
           points to pnv_dma_get_required_mask() (platforms/powernv/setup.c)
        2) device is PCI, therefore call pnv_pci_dma_get_required_mask()
           (platforms/powernv/pci.c)
        3) call phb->dma_get_required_mask if it exists
        4) it only exists in the ioda case, where it points to
             pnv_pci_ioda_dma_get_required_mask() (platforms/powernv/pci-ioda.c)

      New call chain:

        0) call dma_get_required_mask() (kernel/dma.c)
        1) device is PCI, therefore call 
pci_controller_ops.dma_get_required_mask
           if it exists
        2) in the ioda case, that points to pnv_pci_ioda_dma_get_required_mask()
           (platforms/powernv/pci-ioda.c)

      In the p5ioc2 case, the call chain remains the same -
      dma_get_required_mask() does not find either a ppc_md call or
      pci_controller_ops call, so it calls __dma_get_required_mask().

      powerpc/mm: Drop CONFIG_PPC_HAS_HASH_64K

      The relation between CONFIG_PPC_HAS_HASH_64K and CONFIG_PPC_64K_PAGES is
      painfully complicated.

      But if we rearrange it enough we can see that PPC_HAS_HASH_64K
      essentially depends on PPC_STD_MMU_64 && PPC_64K_PAGES.

      We can then notice that PPC_HAS_HASH_64K is used in files that are only
      built for PPC_STD_MMU_64, meaning it's equivalent to PPC_64K_PAGES.

      So replace all uses and drop it.

      powerpc/mm: Simplify page size kconfig dependencies

      For config options with only a single value, guarding the single value
      with 'if' is the same as adding a 'depends' statement. And it's more
      standard to just use 'depends'.

      And if the option has both an 'if' guard and a 'depends' we can collapse
      them into a single 'depends' by combining them with &&.

      powerpc/cell: Drop support for 64K local store on 4K kernels

      Back in the olden days we added support for using 64K pages to map the
      SPU (Synergistic Processing Unit) local store on Cell, when the main
      kernel was using 4K pages.

      This was useful at the time because distros were using 4K pages, but
      using 64K pages on the SPUs could reduce TLB pressure there.

      However these days the number of Cell users is approaching zero, and
      supporting this option adds unpleasant complexity to the memory
      management code.

      So drop the option, CONFIG_SPU_FS_64K_LS, and all related code.

      powerpc/mm: Fix pte_pagesize_index() crash on 4K w/64K hash

      The powerpc kernel can be built to have either a 4K PAGE_SIZE or a 64K
      PAGE_SIZE.

      However when built with a 4K PAGE_SIZE there is an additional config
      option which can be enabled, PPC_HAS_HASH_64K, which means the kernel
      also knows how to hash a 64K page even though the base PAGE_SIZE is 4K.

      This is used in one obscure configuration, to support 64K pages for SPU
      local store on the Cell processor when the rest of the kernel is using
      4K pages.

      In this configuration, pte_pagesize_index() is defined to just pass
      through its arguments to get_slice_psize(). However pte_pagesize_index()
      is called for both user and kernel addresses, whereas get_slice_psize()
      only knows how to handle user addresses.

      This has been broken forever, however until recently it happened to
      work. That was because in get_slice_psize() the large kernel address
      would cause the right shift of the slice mask to return zero.

      However in commit 7aa0727f3302 ("powerpc/mm: Increase the slice range to
      64TB"), the get_slice_psize() code was changed so that instead of a
      right shift we do an array lookup based on the address. When passed a
      kernel address this means we index way off the end of the slice array
      and return random junk.

      That is only fatal if we happen to hit something non-zero, but when we
      do return a non-zero value we confuse the MMU code and eventually cause
      a check stop.

      This fix is ugly, but simple. When we're called for a kernel address we
      return 4K, which is always correct in this configuration, otherwise we
      use the slice mask.

      iommu/io-pgtable-arm: Unmap and free table when overwriting with block

      When installing a block mapping, we unconditionally overwrite a non-leaf
      PTE if we find one. However, this can cause a problem if the following
      sequence of events occur:

        (1) iommu_map called for a 4k (i.e. PAGE_SIZE) mapping at some address
            - We initialise the page table all the way down to a leaf entry
            - No TLB maintenance is required, because we're going from invalid
              to valid.

        (2) iommu_unmap is called on the mapping installed in (1)
            - We walk the page table to the final (leaf) entry and zero it
            - We only changed a valid leaf entry, so we invalidate leaf-only

        (3) iommu_map is called on the same address as (1), but this time for
            a 2MB (i.e. BLOCK_SIZE) mapping)
            - We walk the page table down to the penultimate level, where we
              find a table entry
            - We overwrite the table entry with a block mapping and return
              without any TLB maintenance and without freeing the memory used
              by the now-orphaned table.

      This last step can lead to a walk-cache caching the overwritten table
      entry, causing unexpected faults when the new mapping is accessed by a
      device. One way to fix this would be to collapse the page table when
      freeing the last page at a given level, but this would require expensive
      iteration on every map call. Instead, this patch detects the case when
      we are overwriting a table entry and explicitly unmaps the table first,
      which takes care of both freeing and TLB invalidation.

      iwlwifi: mvm: fix a race in D0i3 vs. Tx path

      When we enter D0i3, we must stop TXing otherwise the
      sequence number we use might conflict with the firmware's
      internal TX. In order to do so, we have
      IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
      enter D0i3. There is a bug in this code since we may Tx even
      if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
      mvm->d0i3_ap_sta_id is not set.

      To make sure that we don't have any packet in the Tx path
      while we set mvm->d0i3_ap_sta_id, call synchronize_net only
      after we already set mvm->d0i3_ap_sta_id.

      rt2500usb_validate_eeprom() read data up to 0x6e (EEPROM_CALIBRATE_OFFSET)
      but only 0x6a bytes has been allocated and read from the eeprom.

      This lead to out-of-bound accesses and invalid values for

      rtlwifi: rtl8192cu: Remove and replace routine in hw.c and mac.c

      I remove duplicated routines which related rtl92cu_set_hw_reg().

      1. rtl92c_set_qos() and HW_VAR_AC_PARAM routine are similar code.
      so i replace code with rtlpriv->cfg->ops->set_hw_reg().

      2. rtl92c_set_mac_addr() and 'HW_VAR_ETHER_ADDR' case at
      rtl92cu_set_hw_reg() routine are similar code.
      so i removed rtl92c_set_mac_addr() function.
      also it was not used anywhere.

      3. remove HW_VAR_ACM_CTRL routine in rtl92cu_set_hw_reg().
      if rtl_usb->acm_method is not EACMWAY2_SW, HW_VAR_ACM_CTRL is called
      from HW_VAR_AC_PARAM. but it never called. because acm_method is always
      EACMWAY2_SW. so i remove acm_method check routine
      and HW_VAR_ACM_CTRL routine.

      both usb and pci interface is not used HW_VAR_ACM_CTRL.
      but i can't test pci interface module, so i didn't modify pci code.

      Merge branch 'Identifier-Locator-Addressing'

      Tom Herbert says:

      ====================
      net: Identifier Locator Addressing - Part I

      This patch set provides rudimentary support for Identifier Locator
      Addressing or ILA. The basic concept of ILA is that we split an IPv6
      address into a 64 bit locator and 64 bit identifier. The identifier is
      the identity of an entity in communication ("who"), and the locator
      expresses the location of the entity ("where"). Applications
      use externally visible address that contains the identifier.
      When a packet is actually sent, a translation is done that
      overwrites the first 64 bits of the address with a locator.
      The packet can then be forwarded over the network to the host where
      the addressed entity is located. At the receiver, the reverse
      translation is done so the that the application sees the original,
      untranslated address. Presumably an external control plane will
      provide identifier->locator mappings.

      v2:
        - Fix compilation erros when LWT not configured
        - Consolidate ILA into a single ila.c

      v3:
        - Change pseudohdr argument od inet_proto_csum_replace functions to
          be a bool

      v4:
        - In ila_build_state check locator being in netlink params before
          allocating tunnel state

      The data path for ILA is a simple NAT translation that only operates
      on the upper 64 bits of a destination address in IPv6 packets. The
      basic process is:

         1) Lookup 64 bit identifier (lower 64 bits of destination)
         2) If a match is found
            a) Overwrite locator (upper 64 bits of destination) with
               the new locator
            b) Adjust any checksum that has destination address included in
               pseudo header
         3) Send or receive packet

      ILA is a means to implement tunnels or network virtualization without
      encapsulation. Since there is no encapsulation involved, we assume that
      stateless support in the network for IPv6 (e.g. RSS, ECMP, TSO, etc.)
      just works. Also, since we're minimally changing the packet many of
      the worries about encapsulation (MTU, checksum, fragmentation) are
      not relevant. The downside is that, ILA is not extensible like other
      encapsulations (GUE for instance) so it might not be appropriate for
      all use cases. Also, this only makes sense to do in IPv6!

      A key aspect of ILA is performance. The intent is that ILA would be
      used in data centers in virtualizing tasks or jobs. In the fullest
      incarnation all intra data center communications might be targeted to
      virtual ILA addresses. This is basically adding a new virtualization
      capability to the existing services in a datacenter, so there is a
      strong expectation is that this does not degrade performance for
      existing applications.

      Performance seems to be dependent on how ILA is hooked into kernel.
      ILA can be implemented under some different models:

        - Mechanically it is a form a stateless DNAT
        - It can be thought of as a type of (source) routing
        - As a functional replacement of encapsulation

      In this patch set we hook into the data path using Light Weight
      Tunnels (LWT) infrastructure. As part of that, we add support in LWT
      to redirect dst input. iproute will be modified to take a new ila encap
      type. ILA can be configured like:

      ip route add 3333:0:0:1:5555:0:2:0/128 \
         encap ila 2001:0:0:2 via 2401:db00:20:911a:face:0:27:0

      ip -6 addr add 3333:0:0:1:5555:0:1:0/128 dev eth0

      ip route add table local local 2001:0:0:1:5555:0:1:0/128
         encap ila 3333:0:0:1 dev lo

      So sending to destination 3333:0:0:1:5555:0:2:0 will have destination
      of 2001:0:0:2:5555:0:2:0 on the wire.

      Performance results are below. With ILA we see about a 10% drop in
      pps compared to non-ILA. Much of this drop can be attributed to the
      loss of early demux on input (translation occurs after it is attempted).
      We will address this in the next patch set. Also, IPvlan input path
      does not work with ILA since the routing is bypassed-- this will
      be addressed in a future patch.

      Performance testing:

      Performing netperf TCP_RR with 200 clients:

      Non-ILA baseline
        84.92% CPU utilization
        1861922.9 tps
        93/163/330 50/90/99% latencies

      ILA single destination
        83.16% CPU utilization
        1679683.4 tps
        105/180/332 50/90/99% latencies

      inode: rename i_wb_list to i_io_list

      There's a small consistency problem between the inode and writeback
      naming. Writeback calls the "for IO" inode queues b_io and
      b_more_io, but the inode calls these the "writeback list" or
      i_wb_list. This makes it hard to an new "under writeback" list to
      the inode, or call it an "under IO" list on the bdi because either
      way we'll have writeback on IO and IO on writeback and it'll just be
      confusing. I'm getting confused just writing this!

      So, rename the inode "for IO" list variable to i_io_list so we can
      add a new "writeback list" in a subsequent patch.

      crypto: caam - add support for LS1021A

      LS1021A is a QorIQ SoC having little endian CAAM.

      There are a few differences b/w QorIQ and i.MX from CAAM perspective:

      1. i.MX platforms are somewhat special wrt. 64-bit registers:
      -big endian format at 64-bit level: MSW at address+0 and LSW at address+4
      -little endian format at 32-bit level (within MSW and LSW)
      and thus need special handling.

      2. No CCM (clock controller module) for QorIQ.
      No CAAM clocks to enable / disable.

      A new Kconfig option - CRYPTO_DEV_FSL_CAAM_LE - is added to indicate
      CAAM is little endian (*). It is hidden from the user (to avoid
      misconfiguration); when adding support for a new platform with LE CAAM,
      either the Kconfig needs to be updated or the corresponding defconfig
      needs to indicate that CAAM is LE.
      (*) Using a DT property to provide CAAM endianness would not allow
      for the ifdeffery.

      In order to keep changes to a minimum, the following changes
      are postponed:
      -endianness fix of the last word in the S/G (rsvd2, bpid, offset),
      fields are always 0 anyway;
      -S/G format fix for i.MX7 (yes, i.MX7 support was not added yet,
      but still...)

      It makes no sense to put the instructions for calculating the lock
      value (cpu number + 1) and the clearing of eq bit of cr1 in lbarx/stbcx
      loop. And when the lock is acquired by the other thread, the current
      lock value has no chance to equal with the lock value used by current
      cpu. So we can skip the comparing for these two lock values in the

      powerpc: Add a vga alias node for P1022

      In u-boot, when set the video as console, the name 'vga' is used
      as a general name for the video device, during the fdt_fixup_stdout
      process, the 'vga' name is used to search in the dtb to setup the
      'linux,stdout-path' node. Though the P1022 DIU is not VGA-compatible
      device, to meet the 'vga' name used in u-boot, the vga alias node is
      added for P1022 in this patch. At the same time, a display alias is
      also added so that no other components grow dependencies on the vga
      alias node.

      netfilter: nf_conntrack: add efficient mark to zone mapping

      This work adds the possibility of deriving the zone id from the skb->mark
      field in a scalable manner. This allows for having only a single template
      serving hundreds/thousands of different zones, for example, instead of the
      need to have one match for each zone as an extra CT jump target.

      Note that we'd need to have this information attached to the template as 
at
      the time when we're trying to lookup a possible ct object, we already need
      to know zone information for a possible match when going into
      __nf_conntrack_find_get(). This work provides a minimal implementation for
      a possible mapping.

      In order to not add/expose an extra ct->status bit, the zone structure has
      been extended to carry a flag for deriving the mark.

      netfilter: nf_conntrack: add direction support for zones

      This work adds a direction parameter to netfilter zones, so identity
      separation can be performed only in original/reply or both directions
      (default). This basically opens up the possibility of doing NAT with
      conflicting IP address/port tuples from multiple, isolated tenants
      on a host (e.g. from a netns) without requiring each tenant to NAT
      twice resp. to use its own dedicated IP address to SNAT to, meaning
      overlapping tuples can be made unique with the zone identifier in
      original direction, where the NAT engine will then allocate a unique
      tuple in the commonly shared default zone for the reply direction.
      In some restricted, local DNAT cases, also port redirection could be
      used for making the reply traffic unique w/o requiring SNAT.

      The consensus we've reached and discussed at NFWS and since the initial
      implementation [1] was to directly integrate the direction meta data
      into the existing zones infrastructure, as opposed to the ct->mark
      approach we proposed initially.

      As we pass the nf_conntrack_zone object directly around, we don't have
      to touch all call-sites, but only those, that contain equality checks
      of zones. Thus, based on the current direction (original or reply),
      we either return the actual id, or the default NF_CT_DEFAULT_ZONE_ID.
      CT expectations are direction-agnostic entities when expectations are
      being compared among themselves, so we can only use the identifier
      in this case.

      Note that zone identifiers can not be included into the hash mix
      anymore as they don't contain a "stable" value that would be equal
      for both directions at all times, f.e. if only zone->id would
      unconditionally be xor'ed into the table slot hash, then replies won't
      find the corresponding conntracking entry anymore.

      If no particular direction is specified when configuring zones, the
      behaviour is exactly as we expect currently (both directions).

      Support has been added for the CT netlink interface as well as the
      x_tables raw CT target, which both already offer existing interfaces
      to user space for the configuration of zones.

      Below a minimal, simplified collision example (script in [2]) with
      netperf sessions:

        +--- tenant-1 ---+   mark := 1
        |    netperf     |--+
        +----------------+  |                CT zone := mark [ORIGINAL]
         [ip,sport] := X   +--------------+  +--- gateway ---+
                           | mark routing |--|     SNAT      |-- ... +
                           +--------------+  +---------------+       |
        +--- tenant-2 ---+  |                                     ~~~|~~~
        |    netperf     |--+                +-----------+           |
        +----------------+   mark := 2       | netserver |------ ... +
         [ip,sport] := X                     +-----------+
                                              [ip,port] := Y
      On the gateway netns, example:

        iptables -t raw -A PREROUTING -j CT --zone mark --zone-dir ORIGINAL
        iptables -t nat -A POSTROUTING -o <dev> -j SNAT --to-source <ip> 
--random-fully

        iptables -t mangle -A PREROUTING -m conntrack --ctdir ORIGINAL -j 
CONNMARK --save-mark
        iptables -t mangle -A POSTROUTING -m conntrack --ctdir REPLY -j 
CONNMARK --restore-mark

      conntrack dump from gateway netns:

      Taking this further, test script in [2] creates 200 tenants and runs
      original-tuple colliding netperf sessions each. A conntrack -L dump in
      the gateway netns also confirms 200 overlapping entries, all in 
ESTABLISHED
      state as expected.

      I also did run various other tests with some permutations of the script,
      to mention some: SNAT in random/random-fully/persistent mode, no zones (no
      overlaps), static zones (original, reply, both directions), etc.

      sync: serialise per-superblock sync operations

      When competing sync(2) calls walk the same filesystem, they need to
      walk the list of inodes on the superblock to find all the inodes
      that we need to wait for IO completion on. However, when multiple
      wait_sb_inodes() calls do this at the same time, they contend on the
      the inode_sb_list_lock and the contention causes system wide
      slowdowns. In effect, concurrent sync(2) calls can take longer and
      burn more CPU than if they were serialised.

      Stop the worst of the contention by adding a per-sb mutex to wrap
      around wait_sb_inodes() so that we only execute one sync(2) IO
      completion walk per superblock superblock at a time and hence avoid
      contention being triggered by concurrent sync(2) calls.

      inode: convert inode_sb_list_lock to per-sb

      The process of reducing contention on per-superblock inode lists
      starts with moving the locking to match the per-superblock inode
      list. This takes the global lock out of the picture and reduces the
      contention problems to within a single filesystem. This doesn't get
      rid of contention as the locks still have global CPU scope, but it
      does isolate operations on different superblocks form each other.

      inode: add hlist_fake to avoid the inode hash lock in evict

      Some filesystems don't use the VFS inode hash and fake the fact they
      are hashed so that all the writeback code works correctly. However,
      this means the evict() path still tries to remove the inode from the
      hash, meaning that the inode_hash_lock() needs to be taken
      unnecessarily. Hence under certain workloads the inode_hash_lock can
      be contended even if the inode is never actually hashed.

      To avoid this add hlist_fake to test if the inode isn't actually
      hashed to avoid taking the hash lock on inodes that have never been
      hashed.  Based on Dave Chinner's

      inode: add IOP_NOTHASHED to avoid inode hash lock in evict

      basd on Al's suggestions.  Thanks,

      writeback: plug writeback at a high level

      Doing writeback on lots of little files causes terrible IOPS storms
      because of the per-mapping writeback plugging we do. This
      essentially causes imeediate dispatch of IO for each mapping,
      regardless of the context in which writeback is occurring.

      IOWs, running a concurrent write-lots-of-small 4k files using fsmark
      on XFS results in a huge number of IOPS being issued for data
      writes.  Metadata writes are sorted and plugged at a high level by
      XFS, so aggregate nicely into large IOs. However, data writeback IOs
      are dispatched in individual 4k IOs, even when the blocks of two
      consecutively written files are adjacent.

      Test VM: 8p, 8GB RAM, 4xSSD in RAID0, 100TB sparse XFS filesystem,
      metadata CRCs enabled.

      Kernel: 3.10-rc5 + xfsdev + my 3.11 xfs queue (~70 patches)

      Test:

      $ ./fs_mark  -D  10000  -S0  -n  10000  -s  4096  -L  120  -d
      /mnt/scratch/0  -d  /mnt/scratch/1  -d  /mnt/scratch/2  -d
      /mnt/scratch/3  -d  /mnt/scratch/4  -d  /mnt/scratch/5  -d
      /mnt/scratch/6  -d  /mnt/scratch/7

      Result:

                wall    sys     create rate     Physical write IO
                time    CPU     (avg files/s)    IOPS   Bandwidth

      If I use zero length files, this workload at about 500 IOPS, so
      plugging drops the data IOs from roughly 25,500/s to 1000/s.
      3 lines of code, 35% better throughput for 15% less CPU.

      The benefits of plugging at this layer are likely to be higher for
      spinning media as the IO patterns for this workload are going make a
      much bigger difference on high IO latency devices.....

      involves writing data to hardware registers and waiting for the result.
      This mechanism does not scale well. The queuing of "no wait" devcmds is
      done in firmware memory rather than on the host. Firmware memory is a
      rather more scarce and valuable resource than host memory. A devcmd storm
      from one vf can disrupt the service on other pf/vf. The lack of flow
      control allows for possible denial of server from one VM to another.
      Devcmd2 uses work queue to post the devcmds, just like tx work queue. This
      allows better flow control.

      NVMe: Set queue max segments

      This sets the queue's max segment size to match the device's
      capabilities. The default of 128 is usable until a device's transfer
      capability exceeds 512k, assuming a device page size of 4k. Many nvme
      devices exceed that transfer limit, so this lets the block layer know what
      kind of commands it to allow to form rather than unnecessarily split them.

      One additional segment is added to account for a transfer that may start
      in the middle of a page.

      rhashtable-test: extend to test concurrency

      After having tested insertion, lookup, table walk and removal, spawn a
      number of threads running operations on the same rhashtable. Each of
      them will:

      1) insert it's own set of objects,
      2) lookup every successfully inserted object and finally
      3) remove objects in several rounds until all of them have been removed,
         making sure the remaining ones are still found after each round.

      This should put a good amount of load onto the system and due to
      synchronising thread startup via two semaphores also extensive
      concurrent table access.

      The default number of ten threads returned within half a second on my
      local VM with two cores. Running 200 threads took about four seconds. If
      slow systems suffer too much from this though, the default could be
      lowered or even set to zero so this extended test does not run at all by
      default.

      Test PACKET_FANOUT_CBPF by inserting a cBPF program that selects a
      socket by payload. Requires modifying the test program to send
      packets with multiple payloads.

      Also fix a bug in testing the return value of mmap()

      packet: add classic BPF fanout mode

      Add fanout mode PACKET_FANOUT_CBPF that accepts a classic BPF program
      to select a socket.

      This avoids having to keep adding special case fanout modes. One
      example use case is application layer load balancing. The QUIC
      protocol, for instance, encodes a connection ID in UDP payload.

      Also add socket option SOL_PACKET/PACKET_FANOUT_DATA that updates data
      associated with the socket group. Fanout mode PACKET_FANOUT_CBPF is the
      only user so far.

      dlm: fix reconnecting but not sending data

      There are cases on which lowcomms_connect_sock() is called directly,
      which caused the CF_WRITE_PENDING flag to not bet set upon reconnect,
      specially on send_to_sock() error handling. On this last, the flag was
      already cleared and no further attempt on transmitting would be done.

      As dlm tends to connect when it needs to transmit something, it makes
      sense to always mark this flag right after the connect.

      dlm: replace BUG_ON with a less severe handling

      BUG_ON() is a severe action for this case, specially now that DLM with
      SCTP will use 1 socket per association. Instead, we can just close the
      socket on this error condition and return from the function.

      Also move the check to an earlier stage as it won't change and thus we
      can abort as soon as possible.

      Although this issue was reported when still using SCTP with 1-to-many
      API, this cleanup wouldn't be that simple back then because we couldn't
      close the socket and making sure such event would cease would be hard.
      And actually, previous code was closing the association, yet SCTP layer
      is still raising the new data event. Probably a bug to be fixed in SCTP.

      dlm: use sctp 1-to-1 API

      DLM is using 1-to-many API but in a 1-to-1 fashion. That is, it's not
      needed but this causes it to use sctp_do_peeloff() to mimic an
      kernel_accept() and this causes a symbol dependency on sctp module.

      By switching it to 1-to-1 API we can avoid this dependency and also
      reduce quite a lot of SCTP-specific code in lowcomms.c.

      The caveat is that now DLM won't always use the same src port. It will
      choose a random one, just like TCP code. This allows the peers to
      attempt simultaneous connections, which now are handled just like for
      TCP.

      Even more sharing between TCP and SCTP code on DLM is possible, but it
      is intentionally left for a later commit.

      Note that for using nodes with this commit, you have to have at least
      the early fixes on this patchset otherwise it will trigger some issues
      on old nodes.

      When a connection have issues DLM may need to close it.  Therefore we

      and not just when dlm is not willing to use this connection anymore.

      Also, if we don't clear CF_CONNECT_PENDING flag, the error handling
      routines won't be able to re-connect as lowcomms_connect_sock() will
      check for it.

      dlm: fix connection stealing if using SCTP

      When using SCTP and accepting a new connection, DLM currently validates
      if the peer trying to connect to it is one of the cluster nodes, but it
      doesn't check if it already has a connection to it or not.

      If it already had a connection, it will be overwritten, and the new one
      will be used for writes, possibly causing the node to leave the cluster
      due to communication breakage.

      Still, one could DoS the node by attempting N connections and keeping
      them open.

      As said, but being explicit, both situations are only triggerable from
      other cluster nodes, but are doable with only user-level perms.

      lwtunnel: rename ip lwtunnel attributes

      We already have IFLA_IPTUN_ netlink attributes. The IP_TUN_ attributes 
look
      very similar, yet they serve very different purpose. This is confusing for
      anyone trying to implement a user space tool supporting lwt.

      As the IP_TUN_ attributes are used only for the lightweight tunnels, 
prefix
      them with LWTUNNEL_IP_ instead to make their purpose clear. Also, it's 
more
      logical to have them in lwtunnel.h together with the encap enum.

      Commit 0b50dc4fc971 ("Convert smsc911x to use ACPI as well as DT") makes
      the call to smsc911x_probe_config() unconditional, and no longer fails if
      there is no device node. device_get_phy_mode() is called unconditionally,
      and if there is no phy node configured returns an error code. This error
      code is assigned to phy_interface, and interpreted elsewhere in the code
      as valid phy mode. This in turn causes qemu to crash when running a
      variant of realview_pb_defconfig.

      drm/radeon: Don't take dev->struct_mutex in pm functions

      We already grab 2 device-global locks (write-sema rdev->pm.mclk_lock
      and rdev->ring_lock), adding another global mutex won't serialize this
      code more. And since there's really nothing interesting that gets
      protected in radeon by dev->struct mutex (we only have the global z
      buffer owners and it's still serializing gem bo destruction in the drm
      core - which is irrelevant since radeon uses ttm anyway internally)
      this doesn't add protection. Remove it.

      drm/radeon: Don't take dev->struct_mutex in bo_force_delete

      It really doesn't protect anything which doesn't have other locks
      already. Also this is run from driver unload code so not much need for
      locks anyway.

      drm/amdgpu: remove VI hw bug workaround v3

      The workaround simply doesn't work because VM mappings
      are controlled by userspace not the kernel.

      Additional to that this is just a performance problem
      which happens if you have holes in your VM mapping.

      v2: adjust virtual addr alignment as well.
      v3: fix trivial warning

      drm/amd: add basic scheduling framework

      run queue:
      A set of entities scheduling commands for the same ring. It
      implements the scheduling policy that selects the next entity to
      emit commands from.

      entity:
      A scheduler entity is a wrapper around a job queue or a group of
      other entities. This can be used to build hierarchies of entities.
      For example all job queue entities belonging to the same process
      may be placed in a higher level entity and scheduled against other
      process entities.
      Entities take turns emitting jobs from their job queue to the
      corresponding hardware ring, in accordance with the scheduler policy.

      drm/amd: Add CGS interfaces

      CGS (Common Graphics Services) is an AMD cross component
      abstraction layer to designed to better encapsulate
      specific IP block drivers so different teams can effectively
      work on differnet IP block drivers independently. It provides
      a common interface for things like accessing registers,
      allocating GPU memory, and registering interrupt sources.
      The plan is to eventually move more and more IP drivers to
      this interface.  The first user is the ACP IP driver.

      regulator: core: Define regulator_set_voltage_triplet()

      Voltage tolerance isn't necessarily same on both sides of the target
      voltage and regulator_set_voltage_tol() wouldn't be suitable in such
      cases.

      Add another routine regulator_set_voltage_triplet(), which accepts
      target, min and max voltages as arguments.

      This first tries to set the voltage between the target voltage and the
      upper limit, then fall back on the full range. The idea behind this is
      to set regulator's voltage as close to the target voltage, as possible.

      Based on regulator_set_voltage_tol().

      Merge branch 'iff_no_queue'

      Phil Sutter says:

      ====================
      net: introduce IFF_NO_QUEUE as successor of zero tx_queue_len

      This series adds a new private net_device flag indicating that a device 
may
      (and probably should) be used without a queueing discipline attached to 
it.
      This is already common practice for many virtual device types like e.g.
      loopback, VLAN (802.1Q) or bridges (802.1D). The reason for this is that 
these
      devices lack an underlying layer which could impose back pressure and 
therefore
      making a TX queue necessary to not slow down senders.

      Up to now, drivers being aware of the above applying to them set
      dev->tx_queue_len to zero to indicate no qdisc should be attached to the
      interface they drive and the kernel reacts upon this by assigning the noop
      qdisc instead of the default pfifo_fast. This implicit agreement though 
leads
      to an inconvenient situation once a user tries to attach a real qdisc to 
these
      devices, as the formerly special tx_queue_len value becomes a regular one,
      limiting the queue to zero packets and thus prevents any TX from 
happening. To
      overcome this, practically all qdisc implementations intercept and 
sanitize the
      malicious value.

      With this series applied, drivers may signal the lack of need for a qdisc
      without having to tamper with tx_queue_len, making fallbacks in qdiscs and
      caveats in userspace unnecessary.

      Upon upstream acceptance, this series will be followed up by a set of 
patches
      converting device drivers, adding a warning so out-of-tree driver authors 
get
      aware of this change and dropping all special handling of tx_queue_len in
      net/sched/.

      NFS: Don't let the ctime override attribute barriers.

      Chuck reports seeing cases where a GETATTR that happens to race
      with an asynchronous WRITE is overriding the file size, despite
      the attribute barrier being set by the writeback code.

      The culprit turns out to be the check in nfs_ctime_need_update(),
      which sees that the ctime is newer than the cached ctime, and
      assumes that it is safe to override the attribute barrier.
      This patch removes that override, and ensures that attribute
      barriers are always respected.

      time: Always make sure wall_to_monotonic isn't positive

      Two issues were found on an IMX6 development board without an
      enabled RTC device(resulting in the boot time and monotonic
      time being initialized to 0).

      Issue 1:exportfs -a generate:
             "exportfs: /opt/nfs/arm does not support NFS export"
      Issue 2:cat /proc/stat:
             "btime 4294967236"

      The same issues can be reproduced on x86 after running the
      following code:
        int main(void)
        {
            struct timeval val;
            int ret;

            val.tv_sec = 0;
            val.tv_usec = 0;
            ret = settimeofday(&val, NULL);
            return 0;
        }

      Two issues are different symptoms of same problem:
      The reason is a positive wall_to_monotonic pushes boot time back
      to the time before Epoch, and getboottime will return negative
      value.

      In symptom 1:
                negative boot time cause get_expiry() to overflow time_t
                when input expire time is 2147483647, then cache_flush()
                always clears entries just added in ip_map_parse.
      In symptom 2:
                show_stat() uses "unsigned long" to print negative btime
                value returned by getboottime.

      This patch fix the problem by prohibiting time from being set to a value 
which
      would cause a negative boot time. As a result one can't set the 
CLOCK_REALTIME
      time prior to (1970 + system uptime).

      time: Fix nanosecond file time rounding in timespec_trunc()

      timespec_trunc() avoids rounding if granularity <= nanoseconds-per-jiffie
      (or TICK_NSEC). This optimization assumes that:

       1. current_kernel_time().tv_nsec is already rounded to TICK_NSEC (i.e.
          with HZ=1000 you'd get 1000000, 2000000, 3000000... but never 
1000001).
          This is no longer true (probably since hrtimers introduced in 2.6.16).

       2. TICK_NSEC is evenly divisible by all possible granularities. This may
          be true for HZ=100, 250, 1000, but obviously not for HZ=300 /
          TICK_NSEC=3333333 (introduced in 2.6.20).

      Thus, sub-second portions of in-core file times are not rounded to on-disk
      granularity. I.e. file times may change when the inode is re-read from 
disk
      or when the file system is remounted.

      This affects all file systems with file time granularities > 1 ns and < 
1s,
      e.g. CEPH (1000 ns), UDF (1000 ns), CIFS (100 ns), NTFS (100 ns) and FUSE
      (configurable from user mode via struct fuse_init_out.time_gran).

      Steps to reproduce with e.g. UDF:

        $ dd if=/dev/zero of=udfdisk count=10000 && mkudffs udfdisk
        $ mkdir udf && mount udfdisk udf
        $ touch udf/test && stat -c %y udf/test
        2015-06-09 10:22:56.130006767 +0200
        $ umount udf && mount udfdisk udf
        $ stat -c %y udf/test
        2015-06-09 10:22:56.130006000 +0200

      Remounting truncates the mtime to 1 µs.

      Fix the rounding in timespec_trunc() and update the documentation.

      timespec_trunc() is exclusively used to calculate inode's [acm]time 
(mostly
      via current_fs_time()), and always with super_block.s_time_gran as second
      argument. So this can safely be changed without side effects.

      Note: This does _not_ fix the issue for FAT's 2 second mtime resolution,
      as super_block.s_time_gran isn't prepared to handle different ctime /
      mtime / atime resolutions nor resolutions > 1 second.

      timer_list: Add the base offset so remaining nsecs are accurate for non 
monotonic timers

      I noticed for non-monotonic timers in timer_list, some of the
      output looked a little confusing.

      For example:
       #1: <0000000000000000>, posix_timer_fn, S:01, hrtimer_start_range_ns, 
leap-a-day/2360
       # expires at 1434412800000000000-1434412800000000000 nsecs [in 
1434410725062375469 to 1434410725062375469 nsecs]

      You'll note the relative time till the expiration "[in xxx to
      yyy nsecs]" is incorrect. This is because its printing the delta
      between CLOCK_MONOTONIC time to the CLOCK_REALTIME expiration.

      This patch fixes this issue by adding the clock offset to the
      "now" time which we use to calculate the delta.

      has no way of telling us).  Add FMODE_WRITE to the mode argument

      It is rather pointless to test the value of transport->inet after
      calling xs_reset_transport(), since it will always be zero, and
      so we will never see any exponential back off behaviour.
      Also don't force early connections for SOFTCONN tasks. If the server
      disconnects us, we should respect the exponential backoff.

      NFS: nfs_set_pgio_error sometimes misses errors

      We should ensure that we always set the pgio_header's error field
      if a READ or WRITE RPC call returns an error. The current code depends
      on 'hdr->good_bytes' always being initialised to a large value, which
      is not always done correctly by callers.
      When this happens, applications may end up missing important errors.

      ASoC: mediatek: Remove AIF widgets for backend DAIs

      DAPM core already creates widgets for DAIs. It is not necessary
      to declare them by SND_SOC_DAPM_AIF_IN/SND_SOC_DAPM_AIF_OUT.
      Furthermore, original codes use backend DAI's stream name to be the AIF
      widget name. It causes the same widget to be created twice, and after
      commit 92fa12426741 ("ASoC: dapm: Add new widgets to the end of the
      widget list") the first created widget (by snd_soc_dapm_new_controls)
      is used, not the 2nd created one (by snd_soc_dapm_new_dai_widgets),
      so audio path is broken.

      bnx2: Fix bandwidth allocation for some MF modes

      Management firmware tells driver in case bandwidth configuration for
      a specific function exists, but [regretably] the same field has different
      meanings depending on the multi-function mode - it can either be
      a percentile value or an actual speed.

      For newer multi-function modes current logic is incorrect -
      driver understands values as actual speeds instead of percentages,
      causing the resulting chip configuration to be incorrect.

      ath10k: refactor phyerr event handlers

      Existing phyerr event handlers directly uses phyerr header format
      (ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
      exactly on how firmware packs it. This is the problem in 10.4 fw
      specific phyerr event handling where it uses different phyerror
      header format. Before adding 10.4 specific handler, little bit of
      refactor is done in existing phyerr handlers.

      Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
      struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
      firmware specific header format in the code. So that firmware specific
      phyerror handlers can populate values to abstracted structures and
      the following code can use abstracted struct for further operation.

      .pull_phyerr_hdr is added newly to pull common phyerr header info
      like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
      handler is changed and called to parse every sub phyerrs in the event.

      Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

      pwm-pca9685: Support changing the output frequency

      Previously, period_ns and duty_ns were only used to determine the
      ratio of ON and OFF time, the default frequency of 200 Hz was never
      changed.
      The PCA9685 however is capable of changing the PWM output frequency,
      which is expected when changing the period.

      This patch configures the prescaler accordingly, using the formula
      and notes provided in the PCA9685 datasheet.
      Bounds checking for the minimum and maximum frequencies, last updated
      in revision v.4 of said datasheet, is also added.

      The prescaler is only touched if the period changed, because we have to
      put the chip into sleep mode to unlock the prescale register.
      If it is changed, the PWM output frequency changes for all outputs,
      because there is one prescaler per chip. This is documented in the
      PCA9685 datasheet and in the comments.

      If the duty cycle is not changed at the same time as the period, then
      we restart the PWM output using the duty cycle to period ratio from
      before the period change.
      When using LEDs for example, previously set brightness levels stay the
      same when the frequency changes.

      pwm-pca9685: Fix several driver bugs

      Problems:
      - When duty_ns == period_ns, the full OFF bit was not cleared and the
        PWM output of the PCA9685 stayed off.
      - When duty_ns == period_ns and the catch-all channel was used, the
        ALL_LED_OFF_L register was not cleared.
      - The full ON bit was not cleared when setting the OFF time, therefore
        the exact OFF time was ignored when setting a duty_ns < period_ns

      Solution: Clear both OFF registers when setting full ON and clear the
      full ON bit when changing the OFF registers.

      nbd: Fix timeout detection

      At the moment the nbd timeout just detects hanging tcp operations. This
      is not enough to detect a hanging or bad connection as expected of a
      timeout.

      This patch redesigns the timeout detection to include some more cases.
      The timeout is now in relation to replies from the server. If the server
      does not send replies within the timeout the connection will be shut
      down.

      The patch adds a continous timer 'timeout_timer' that is setup in one of
      two cases:
       - The request list is empty and we are sending the first request out to
         the server. We want to have a reply within the given timeout,
         otherwise we consider the connection to be dead.
       - A server response was received. This means the server is still
         communicating with us. The timer is reset to the timeout value.

      The timer is not stopped if the list becomes empty. It will just trigger
      a timeout which will directly leave the handling routine again as the
      request list is empty.

      The whole patch does not use any additional explicit locking. The
      list_empty() calls are safe to be used concurrently. The timer is locked
      internally as we just use mod_timer and del_timer_sync().

      The patch is based on the idea of Michal Belczyk with a previous
      different implementation.

      scatterlist: allow limited chaining without ARCH_HAS_SG_CHAIN

      There are a couple of uses of struct scatterlist that never go to
      the dma_map_sg() helper and thus don't care about ARCH_HAS_SG_CHAIN
      which indicates that we can map chained S/G list.

      The most important one is the crypto code, which currently has
      to open code a few helpers to always allow chaining.  This patch
      removes a few #ifdef ARCH_HAS_SG_CHAIN statements so that we can
      switch the crypto code to these common helpers.

      perf tools: Take Intel PT into use

      To record an AUX area, the weak function auxtrace_record__init() must be
      implemented.

      Equally to decode an AUX area, the AUX area tracing type must be added
      to the perf_event__process_auxtrace_info() function.

      This patch makes those two changes plus hooks up default config for the
      intel_pt PMU.  Also some brief documentation is provided for using the
      tools with intel_pt.

      perf tools: Add Intel PT support

      Add support for Intel Processor Trace.

      Intel PT support fits within the new auxtrace infrastructure.  Recording
      is supporting by identifying the Intel PT PMU, parsing options and
      setting up events.

      Decoding is supported by queuing up trace data by cpu or thread and then
      decoding synchronously delivering synthesized event samples into the
      session processing for tools to consume.

      perf tools: Add Intel PT decoder

      Add support for decoding an Intel Processor Trace.

      Intel PT trace data must be 'decoded' which involves walking the object
      code and matching the trace data packets.

      The decoder requests a buffer of binary data via a get_trace()
      call-back, which it decodes using instruction information which it gets
      via another call-back walk_insn().

      This essentially provides intel_pt_get_insn() which takes a binary

      instruction and then categorizes it for consumption by an Intel PT

      ath10k: fix invalid survey reporting for QCA99X0

      There are three WMI_CHAN_INFO events reported per channel
      in QCA99X0 firmware. First one is a notification at the begining
      of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
      second one is a notification at the end of the dwell time with cmd_flag
      CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
      with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
      the channel. Since there is a new state before the completion, the handler
      is to fixed so that the counts are deducted from the ones reported with
      CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.
      Without this fix there will be lots of 0 msecs reported as active
      and busy time.

      ath10k: wake up queue upon vif creation

      Vif's vdev_id is used as queue number. However due
      to the tx pausing design in ath10k it was possible
      for a new interface to be created with its tx
      queue stopped (via ieee80211_stop_queues). This
      could in turn leave the interface inoperable until
      ath10k_mac_tx_unlock() was called.

      This problem only affected multi-vif scenarios when
      new interfaces were created some time later after
      other interfaces have been running for some time
      and had Tx queue full at some point prior.

      Possible manifestation of the bug was
      authentication timeout for a client vif.

      ath10k: wake up offchannel queue properly

      Once HTT Tx queue got full offchannel queue was
      stopped and never woken up again. This broke, e.g.
      P2P. This could be reproduced after running a lot
      of traffic enough to saturate 100% of the driver
      Tx queue and then trying to send offchannel
      traffic.

      gpiolib: irqchip: use different lockdep class for each gpio irqchip

      Since IRQ chip helpers were introduced drivers lose ability to
      register separate lockdep classes for each registered GPIO IRQ
      chip and the gpiolib now is using shared lockdep class for
      all GPIO IRQ chips (gpiochip_irq_lock_class).
      As result, lockdep will produce warning when there are min two
      stacked GPIO chips and all of them are interrupt controllers.

      HW configuration which generates lockdep warning (TI dra7-evm):

      [SOC GPIO bankA.gpioX]
        <- irq - [pcf875x.gpioY]
                  <- irq - DevZ.enable_irq_wake(pcf_gpioY_irq);
      The issue was reported in [1] and discussed [2].

      mmc: dw_mmc: add quirk for broken data transfer over scheme

      This patch add a new quirk to add a s/w timer to notify the driver
      to terminate current transfer and report a data timeout to the core,
      if DTO interrupt does NOT come within the given time.

      dw_mmc call mmc_request_done func to finish transfer depends on
      DTO interrupt. If DTO interrupt does not come in sending data state,
      the current transfer will be blocked.

      We got the reply from synopsys:
      There are two counters but both use the same value of [31:8] bits.
      Data timeout counter doesn't wait for stop clock and you should get
      DRTO even when the clock is not stopped.
      Host Starvation timeout counter is triggered with stop clock condition.

      This means that host should get DRTO and DTO interrupt.

      But this case really exists, when driver reads tuning data from
      card on RK3288-pink2 board. I measured waveforms by oscilloscope
      and found that card clock was always on and data lines were always
      holded high level in sending data state.

      There are two possibility that data over interrupt doesn't come in
      reading data state on RK3X SoCs:
      - get command done interrupt, but doesn't get any data-related interrupt.
      - get data error interrupt, but doesn't get data over interrupt.

      mmc: dw_mmc: fix pio mode when internal dmac is enabled

      The dw_mci_init_dma() may decide to not use dma, but pio instead, caused
      by things like wrong dma settings in the system.

      Till now the code dw_mci_init_slot() always assumed that dma is available
      when CONFIG_MMC_DW_IDMAC was defined, ignoring the host->use_dma var
      set during dma init.

      So when now the dma init failed for whatever reason, the transfer sizes
      would still be set for dma transfers, especially including the maximum
      block-count calculated from host->ring_size and resulting in a

      [    4.991109] ------------[ cut here ]------------

      [    4.991113] Internal error: Oops - BUG: 0 [#1] SMP ARM

      because host->ring_size is 0 in this case and the slot init code uses
      the wrong code to calculate the values.

      Fix this by selecting the correct calculations using the host->use_dma
      variable instead of the CONFIG_MMC_DW_IDMAC config option.

      mmc: dw_mmc: handle data blocks > than 4kB if IDMAC is used

      As per DW MobileStorage databook "each descriptor can transfer up to 4kB
      of data in chained mode", moreover buffer size that is put in "des1" is
      limited to 13 bits, i.e. for example on attempt to
      IDMAC_SET_BUFFER1_SIZE(desc, 8192) size value that's effectively written
      will be 0.

      On the platform with 8kB PAGE_SIZE I see dw_mmc gets data blocks in
      SG-list of 8kB size and that leads to unpredictable behavior of the
      SD/MMC controller.

      In particular on write to FAT partition of SD-card the controller will
      stuck in the middle of DMA transaction.

      Solution to the problem is simple - we need to pass large (> 4kB) data
      buffers to the controller via multiple descriptors. And that's what
      that change does.

      What's interesting I did try original driver on same platform but
      configured with 4kB PAGE_SIZE and may confirm that data blocks passed
      in SG-list to dw_mmc never exeed 4kB limit - that explains why nobody
      ever faced a problem I did.

      some unknown issue. But the driver doesn't assign sdio_irq_thread
      pointer. This will block the resume of kernel. This patch is used
      to avoid using NULL sdio_irq_thread pointer.

      mmc: omap_hsmmc: call omap_hsmmc_set_power directly

      If no pdata.set_power was set by the platform code, the driver
      was updating pdata with its own fallback function. This is a no-no
      since pdata shall be read-only.
      This patch pushes the check 'pdata->set_power != NULL' down into
      the fallback functions. If pdata.set_power is really set, it calls them
      and exits, otherwise the fallback code is used.

      Documentation: dt: update ti,am33xx-hsmmc swakeup workaround

      Before 5b83b2234be6733cf the driver was hard coding the wakeup irq to
      be active low. The generic pm wakeirq does not override the active
      high/low parameter, hence it must be specified correctly in the
      device tree.
      Mind that SDIO IRQ is active low as defined in the SDIO specification

      gpio/grgpio: fix deadlock in grgpio_irq_unmap()

      As reported by Alexey Khoroshilov:

          grgpio_irq_unmap() code looks quite suspicious regarding usage of
          priv->bgc.lock spinlock.

          It locks the spinlock in line 310:

        spin_lock_irqsave(&priv->bgc.lock, flags);

          and then it can call grgpio_set_imask() in line 317:

        grgpio_set_imask(priv, i, 0);

          But grgpio_set_imask() unconditionally locks the spinlock by itself.

      Fix this by moving the spinlock acquisition outside of
      grgpio_set_imask().

      Found by Linux Driver Verification project (linuxtesting.org).

      x86/smpboot: Remove SIPI delays from cpu_up()

      MPS 1.4 example code shows the following required delays during processor
      on-lining:

        INIT
         udelay(10,000)
        SIPI
         udelay(200)
        SIPI
         udelay(200) /* Linux actually implements this as udelay(300) */

      Linux skips the udelay(10,000) on modern processors.
      This patch removes the udelay(200) after each SIPI
      on those same processors.

      All three legacy delays can be restored by the cmdline
      "cpu_init_udelay=10000".

      As measured by analyze_suspend.py, this patch speeds
      processor resume time on my desktop from 2.4ms to 1.8ms, per AP.

      x86/smpboot: Remove udelay(100) when polling cpu_callin_map

      After the BSP sends INIT/SIPI/SIP to the AP and sees the AP
      in the cpu_initialized_map, it sets the AP loose via the
      cpu_callout_map, and waits for it via the cpu_callin_map.

      The BSP polls the cpu_callin_map with a udelay(100)
      and a schedule() in each iteration.

      The udelay(100) adds no value.

      For example, on my 4-CPU dekstop, the AP finishes
      cpu_callin() in under 70 usec and sets the cpu_callin_mask.
      The BSP, however, doesn't see that setting until over 30 usec
      later, because it was still running its udelay(100)
      when the AP finished.

      Deleting the udelay(100) in the cpu_callin_mask polling loop,
      saves from 0 to 100 usec per Application Processor.

      x86/smpboot: Remove udelay(100) when polling cpu_initialized_map

      After the BSP sends the APIC INIT/SIPI/SIPI to the AP,
      it waits for the AP to come up and indicate that it is alive
      by setting its own bit in the cpu_initialized_mask.

      Linux polls for up to 10 seconds for this to happen.
      Each polling loop has a udelay(100) and a call to schedule().

      The udelay(100) adds no value.

      For example, on my desktop, the BSP waits for the
      other 3 CPUs to come on line at boot for 305, 404, 405 usec.
      For resume from S3, it waits 317, 404, 405 usec.

      But when the udelay(100) is removed, the BSP waits
      305, 310, 306 for boot, and 305, 307, 306 for resume.

      So for both boot and resume, removing the udelay(100)
      speeds online by about 100us in 2 of 3 cases.

      drm/tegra: Changes for v4.3-rc1

      There are a bunch of non-critical fixes here that I've collected over
      the past few months, but the biggest part is Tegra210 support, in the
      DC, DSI and SOR/HDMI drivers.

      Also this finally restores DPMS with atomic mode-setting, something
      that has been broken since the conversion and which I had originally
      expected to take far less longer to fix.

      Summary:
      - Clean up HDMI and MIXER parts
      - Clean up legacy structures specific to Exynos DRM
        . This patch series removes existing exyons_drm_display and
          exynos_drm_encoder structures specific to Exynos DRM, and
          makes them to replace with common drm_encoder structure.
          With cleanup patch, we removes exynos_drm_encoder module.
      - Clean up gem, dmabuf and buffer modules
        . This patch series replaces existing Exynos DRM dmabuf codes
          with common drm prime ones, and embeds all codes of exynos_drm_buf
          into exynos_drm_gem module.
          With cleanup patch, we removes exynos_drm_buf and exynos_drm_dmabuf
          modules.
      - And some fixups.

      fib_lookup() forces FIB_LOOKUP_NOREF flag, while fib_table_lookup()
      does not.

      xtensa: implement fake NMI

      In case perf IRQ is the highest of the medium-level IRQs, and is alone
      on its level, it may be treated as NMI:
      - LOCKLEVEL is defined to be one level less than EXCM level,
      - IRQ masking never lowers current IRQ level,
      - new fake exception cause code, EXCCAUSE_MAPPED_NMI is assigned to that
        IRQ; new second level exception handler, do_nmi, assigned to it
        handles it as NMI,
      - atomic operations in configurations without s32c1i still need to mask
        all interrupts.

      xtensa: fix kernel register spilling

      call12 can't be safely used as the first call in the inline function,
      because the compiler does not extend the stack frame of the bounding
      function accordingly, which may result in corruption of local variables.

      If a call needs to be done, do call8 first followed by call12.

      For pure assembly code in _switch_to increase stack frame size of the
      bounding function.

      xtensa: implement counting and sampling perf events

      Xtensa Performance Monitor Module has up to 8 32 bit wide performance
      counters. Each counter may be enabled independently and can count any
      single type of hardware performance events. Event counting may be enabled
      and disabled globally (per PMM).
      Each counter has status register with bits indicating if the counter has
      been overflown and may be programmed to raise profiling IRQ on overflow.
      This IRQ is used to rewind counters and allow for counting more than 2^32
      samples for counting events and to report samples for sampling events.

      For more details see Tensilica Debug User's Guide, chapter 8
      "Performance monitor module".

      xtensa: keep exception/interrupt stack continuous

      Restore original a0 in the kernel exception stack frame. This way it
      looks like the frame that got interrupt/exception did alloca (copy a0 and
      a1 spilled under old stack to the new location as well) to save registers
      and then did a call to handler.
      The point where interrupt/exception was taken is not in the stack chain,
      only in pt_regs (call4 from that address can be simulated to keep it in
      the stack trace).

      scripts/kernel-doc: Adding cross-reference links to html documentation.

      Functions, Structs and Parameters definitions on kernel documentation
      are pure cosmetic, it only highlights the element.

      To ease the navigation in the documentation we should use <links> inside
      those tags so readers can easily jump between methods directly.

      This was discussed in 2014[1] and is implemented by getting a list
      of <refentries> from the DocBook XML to generate a database. Then it looks
      for <function>,<structnames> and <paramdef> tags that matches the ones in
      the database. As it only links existent references, no broken links are
      added.

      CONFIG_CXL_EEH is for CXL's EEH related code.

      Other drivers can depend on or #ifdef on this symbol to configure
      PERST behaviour, allowing CXL to participate in the EEH process.

      Currently vb2 core acquires mmap_sem just around call to
      __qbuf_userptr(). However since commit f035eb4e976ef5 (videobuf2: fix
      lockdep warning) it isn't necessary to acquire it so early as we no
      longer have to drop queue mutex before acquiring mmap_sem. So push
      acquisition of mmap_sem down into .get_userptr memop so that the
      semaphore is acquired for a shorter time and it is clearer what it is
      needed for.

      Note that we also need mmap_sem in .put_userptr memop since that ends up
      calling vb2_put_vma() which calls vma->vm_ops->close() which should be
      called with mmap_sem held. However we didn't hold mmap_sem in some code
      paths anyway (e.g. when called via vb2_ioctl_reqbufs() ->
      __vb2_queue_free() -> vb2_dma_sg_put_userptr()) and getting mmap_sem in
      put_userptr() introduces a lock inversion with queue->mmap_lock in the
      above mentioned call path.

      Luckily this whole locking mess will get resolved once we convert
      videobuf2 core to the new mm helper which avoids the need for mmap_sem
      in .put_userptr memop altogether.

      [media] sr030pc30: don't read a new pointer

      sr030pc30_get_fmt() can only succeed if both info->curr_win and
      info->curr_fmt are not NULL.

      If one of those vars are null, the curent code would call:
        ret = sr030pc30_set_params(sd);

      If the curr_win is null, it will return -EINVAL, as it would be
      expected. However, if curr_fmt is NULL, the function won't
      set it.

      The code will then try to read from it:

              mf->code        = info->curr_fmt->code;
              mf->colorspace  = info->curr_fmt->colorspace;

      with obviouly won't work.

      This got reported by smatch:

      iwlwifi: convert hex_dump_to_buffer() to %*ph

      There is no need to use hex_dump_to_buffer() in the cases like this:

        hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);      /* len 
<= 16 */
        sprintf("%s\n", outbuf);

      since it maybe easily converted to simple:

        sprintf("%*ph\n", len, buf);

      Note: it seems in one case the output is groupped by 2 bytes and looks 
like a

      exynos_encoder ops had .create_connector() defined only because we were
      handing off the encoder and connector creation to
      exynos_drm_create_enc_conn(). Without this function we can directly call
      the create_connector function internally in the code, without the need of

      drm/exynos: use KMS version of DRM vblanks functions

      Get rid of legacy DRM vblank function that are less clear to use.
      The new ones basically requires only the crtc as parameters.

      It also clean ups exynos_drm_crtc_finish_pageflip() parameters as a
      consequence.

      drm/exynos: clear channels only when iommu is enabled

      This is simplest solution about reported problem[1]. It's no problem to
      clear channel only when iommu is enabled, if we consider that we cannot
      recognize iommu errors when iommu is disabled and it have been valid
      until now. But this cannot be nice solution.

      drm/msm/dsi: Allow dsi to connect to an external bridge

      There are platforms where the DSI output can be connected to another
      encoder bridge chip (DSI to HDMI, DSI to LVDS etc).

      Add support for external bridge support to the dsi driver. We assume that
      the external bridge chip would be of the type drm_bridge. The dsi driver's
      internal drm_bridge (msm_dsi->bridge) is linked to the external bridge's
      drm_bridge struct.

      In the case we're connected to an external bridge, we don't need to create
      and manage a connector within our driver, it's the bridge driver's
      responsibility to create one.

      v2:
      - Move the external bridge attaching stuff to dsi manager to make things
        cleaner.
      - Force the bridge to connect to a video mode encoder for now (the dsi
        mode flags may have not been populated by modeset_init)

      Create a helper msm_dsi_device_connected() which checks whether we have a

      For now, the check only consists of msm_dsi->panel being non-NULL. Later,

      We currently support only panels connected to dsi output. We're going to
      also support external bridge chips now.

      Change 'panel_node' to 'device_node' in the struct msm_dsi_host and
      'panel_flags' to 'device_flags' in msm_dsi. This makes things sound a

      drm/msm: dsi host: Use device graph parsing to parse connected panel

      The dsi host looks for the connected panel node by parsing for a child
      named 'panel'. This hierarchy isn't very flexible. The connected
      panel is forced to be a child to the dsi host, and hence, a mipi dsi
      device. This isn't suitable for dsi devices that don't use mipi dsi
      as their control bus.

      Follow the of_graph approach of creating ports and endpoints to
      represent the connections between the dsi host and the panel connected
      to it. In our case, the dsi host will only have one output port, linked
      to the panel's input port.

      Update DT binding documentation with device graph usage info.

      v3:
      - Fix return value checks of of_graph_* calls.
      - Don't make port a mandatory DT property
      - Fix defer check when no panel node specified
      - Rename parse_dt func to align with other dsi_host funcs

      ieee802154: 6lowpan: fix packet layer registration

      This patch fixes 802.15.4 packet layer registration when mutliple
      lowpan interfaces will be added. We need to register the packet layer at
      the first lowpan interface and deregister it at the last interface. This
      done by open_count variable which is protected by rtnl.

      Additional do a quiet fix by adding dev_put(real_dev) when netdev
      registration fails, which fix the refcount for the wpan dev.

      The xfstests ext4/305 will mount and unmount the same file system over

      blk-mq: fix race between timeout and freeing request

      Inside timeout handler, blk_mq_tag_to_rq() is called
      to retrieve the request from one tag. This way is obviously
      wrong because the request can be freed any time and some
      fiedds of the request can't be trusted, then kernel oops
      might be triggered[1].

      Currently wrt. blk_mq_tag_to_rq(), the only special case is
      that the flush request can share same tag with the request
      cloned from, and the two requests can't be active at the same
      time, so this patch fixes the above issue by updating tags->rqs[tag]
      with the active request(either flush rq or the request cloned
      from) of the tag.

      Also blk_mq_tag_to_rq() gets much simplified with this patch.

      Given blk_mq_tag_to_rq() is mainly for drivers and the caller must
      make sure the request can't be freed, so in bt_for_each() this
      helper is replaced with tags->rqs[tag].

      blk-mq: fix buffer overflow when reading sysfs file of 'pending'

      There may be lots of pending requests so that the buffer of PAGE_SIZE
      can't hold them at all.

      One typical example is scsi-mq, the queue depth(.can_queue) of
      scsi_host and blk-mq is quite big but scsi_device's queue_depth
      is a bit small(.cmd_per_lun), then it is quite easy to have lots
      of pending requests in hw queue.

      This patch fixes the following warning and the related memory
      destruction.

      ext4: simplify some code in read_mmp_block()

      My static check complains because we have:

        if (!*bh)
                return -ENOMEM;
        if (*bh) {

      The second check is unnecessary.

      I've simplified this code by moving the "if (!*bh)" checks around.  Also
      Andreas Dilger says we should probably print a warning if sb_getblk()
      fails.

      [ Restructured the code so that we print a warning message as well if
        the mmp block doesn't check out, and to print the error code to
        disambiguate between the error cases.  - TYT ]

      ext4: don't manipulate recovery flag when freezing no-journal fs

      At some point along this sequence of changes:

      f6e63f9 ext4: fold ext4_nojournal_sops into ext4_sops
      bb04457 ext4: support freezing ext2 (nojournal) file systems
      9ca9238 ext4: Use separate super_operations structure for no_journal 
filesystems

      ext4 started setting needs_recovery on filesystems without journals
      when they are unfrozen.  This makes no sense, and in fact confuses
      blkid to the point where it doesn't recognize the filesystem at all.

      (freeze ext2; unfreeze ext2; run blkid; see no output; run dumpe2fs,
      see needs_recovery set on fs w/ no journal).

      To fix this, don't manipulate the INCOMPAT_RECOVER feature on
      filesystems without journals.

      change sb_writers to use percpu_rw_semaphore

      We can remove everything from struct sb_writers except frozen
      and add the array of percpu_rw_semaphore's instead.

      This patch doesn't remove sb_writers->wait_unfrozen yet, we keep
      it for get_super_thawed(). We will probably remove it later.

      This change tries to address the following problems:

        - Firstly, __sb_start_write() looks simply buggy. It does
          __sb_end_write() if it sees ->frozen, but if it migrates
          to another CPU before percpu_counter_dec(), sb_wait_write()
          can wrongly succeed if there is another task which holds
          the same "semaphore": sb_wait_write() can miss the result
          of the previous percpu_counter_inc() but see the result
          of this percpu_counter_dec().

        - As Dave Hansen reports, it is suboptimal. The trivial
          microbenchmark that writes to a tmpfs file in a loop runs
          12% faster if we change this code to rely on RCU and kill
          the memory barriers.

        - This code doesn't look simple. It would be better to rely
          on the generic locking code.

          According to Dave, this change adds the same performance
          improvement.

      Note: with this change both freeze_super() and thaw_super() will do
      synchronize_sched_expedited() 3 times. This is just ugly. But:

        - This will be "fixed" by the rcu_sync changes we are going
          to merge. After that freeze_super()->percpu_down_write()
          will use synchronize_sched(), and thaw_super() won't use
          synchronize() at all.

          This doesn't need any changes in fs/super.c.

        - Once we merge rcu_sync changes, we can also change super.c
          so that all wb_write->rw_sem's will share the single ->rss
          in struct sb_writes, then freeze_super() will need only one
          synchronize_sched().

      shift percpu_counter_destroy() into destroy_super_work()

      Of course, this patch is ugly as hell. It will be (partially)
      reverted later. We add it to ensure that other WIP changes in
      percpu_rw_semaphore won't break fs/super.c.

      We do not even need this change right now, percpu_free_rwsem()
      is fine in atomic context. But we are going to change this, it
      will be might_sleep() after we merge the rcu_sync() patches.

      And even after that we do not really need destroy_super_work(),
      we will kill it in any case. Instead, destroy_super_rcu() should
      just check that rss->cb_state == CB_IDLE and do call_rcu() again
      in the (very unlikely) case this is not true.

      So this is just the temporary kludge which helps us to avoid the
      conflicts with the changes which will be (hopefully) routed via
      rcu tree.

      document rwsem_release() in sb_wait_write()

      Not only we need to avoid the warning from lockdep_sys_exit(), the
      caller of freeze_super() can never release this lock. Another thread
      can do this, so there is another reason for rwsem_release().

      Plus the comment should explain why we have to fool lockdep.

  Date:   Mon Jul 20 00:50:55 2015 +0200

      fix the broken lockdep logic in __sb_start_write()

      1. wait_event(frozen < level) without rwsem_acquire_read() is just
         wrong from lockdep perspective. If we are going to deadlock
         because the caller is buggy, lockdep can't detect this problem.

      2. __sb_start_write() can race with thaw_super() + freeze_super(),
         and after "goto retry" the 2nd  acquire_freeze_lock() is wrong.

      3. The "tell lockdep we are doing trylock" hack doesn't look nice.

         I think this is correct, but this logic should be more explicit.
         Yes, the recursive read_lock() is fine if we hold the lock on a
         higher level. But we do not need to fool lockdep. If we can not
         deadlock in this case then try-lock must not fail and we can use
         use wait == F throughout this code.

      Note: as Dave Chinner explains, the "trylock" hack and the fat comment
      can be probably removed. But this needs a separate change and it will
      be trivial: just kill __sb_start_write() and rename do_sb_start_write()
      back to __sb_start_write().

      staging: comedi: adl_pci7x3x: fix digital output on PCI-7230

      The "adl_pci7x3x" driver replaced the "adl_pci7230" and "adl_pci7432"
      drivers in commits 8f567c373c4b ("staging: comedi: new adl_pci7x3x
      driver") and 657f77d173d3 ("staging: comedi: remove adl_pci7230 and
      adl_pci7432 drivers").  Although the new driver code agrees with the
      user manuals for the respective boards, digital outputs stopped working
      on the PCI-7230.  This has 16 digital output channels and the previous
      adl_pci7230 driver shifted the 16 bit output state left by 16 bits
      before writing to the hardware register.  The new adl_pci7x3x driver
      doesn't do that.  Fix it in `adl_pci7x3x_do_insn_bits()` by checking
      for the special case of the subdevice having only 16 channels and
      duplicating the 16 bit output state into both halves of the 32-bit
      register.  That should work both for what the board actually does and
      for what the user manual says it should do.

      staging: comedi: comedi_fops: remove remaining BUG_ON() checks

      The BUG_ON() checks in comedi_subdevice_from_minor() and
      comedi_dev_get_from_subdevice_minor() are not necessary.

      The 'minor' numbers for a given comedi driver are setup by
      comedi_dev_get_from_subdevice_minor() and will always be in
      the correct range.

      Drivers should not crash the kernel, remove the BUG_ON() checks.

      Coverity reports a possible Out-of-bounds access (ARRAY_VS_SINGLETON)
      with the 'const u8 *port' parameter passed to ni6501_port_command().
      This param is an actual array for the SET_PORT_DIR operation, called
      by ni6501_dio_insn_config(). But for the WRITE_PORT and READ_PORT
      operations, called by ni6501_dio_insn_bits(), it is just the address
      of an u8 local variable.

      Fix the coverity issue by changing the parameter to an unsigned int
      and pass the raw values from ni6501_dio_insn_config() and
      ni6501_dio_insn_bits(). ni6501_port_command() then handles the masking
      and shifting needed to load the value into the u8 transmit buffer.

      For consistency, change the access of the 'bitmap' parameter from an
      array access to a pointer operation.

      serial: imx: save and restore context in the suspend path

      This change teaches the imx serial driver to save its
      context and restore it across suspend and resume path.
      To do so, it introduces serial_imx_restore_context()
      and serial_imx_save_context() functions. They use
      a shadow set of registers to save key registers
      and restore them accordingly. These functions can
      be reused on other situations, when the device
      context is lost.

      serial: imx: allow waking up on RTSD

      This patch sets RTSDEN bit when going into idle (Stop mode).
      We add the RTSDEN for the case RTS is sent from
      the remote connection. This way we allow the system
      to wakeup when RTS is received.

      serial: imx: introduce serial_imx_enable_wakeup()

      This change is a code reorganization. Here we introduce
      serial_imx_enable_wakeup() helper function to do
      the job of configuring and preparing wakeup sources
      on imx serial device. The idea is to allow other
      parts of the code to call this function whenever
      the device is known to go to idle.

      serial: imx: remove unbalanced clk_prepare

      The current code attempts to prepare clk_per and clk_ipg
      before using the device. However, the result is an extra
      prepare call on each clock. Here is the output of uart
      clocks (only uart enabled and used as console):

      $  grep uart /sys/kernel/debug/clk/clk_summary
       uart_serial           1            2    80000000          0 0
             uart           1            2    66000000          0 0

      This patch balances the calls of prepares. The result is:

      $  grep uart /sys/kernel/debug/clk/clk_summary
       uart_serial           1            1    80000000          0 0

      The 8250-omap driver requires the DMA-engine driver to support the pause
      command in order to properly turn off programmed RX transfer before the
      driver stars manually reading from the FIFO.
      The lacking support of the requirement has been discovered recently. In
      order to stay safe here we disable RX-DMA completly on probe.

      men_z135_intr() and men_z135_set_termios() both hold the struct

      spinlock, but men_z135_intr() does a spin_lock_irqsave() and

      serial: mxs-auart: keep the AUART unit in reset state when not in use

      Whenever the UART device driver gets closed from userland, the driver
      disables the UART unit and then stops the clocks to save power.

      The bit which disabled the UART unit is described as:

      Â "UART Enable. If this bit is set to 1, the UART is enabled. Data
        transmission and reception occurs for the UART signals. When the
        UART is disabled in the middle of transmission or reception, it
        completes the current character before stopping."

      The important part is the "it completes the current character". Whenever
      a reception is ongoing when the UART gets disabled (including the clock
      off) the statemachine freezes and "remembers" this state on the next
      open() when re-enabling the unit's clock.

      In this case we end up receiving an additional bogus character
      immediately.

      The solution in this change is to switch the AUART unit into its reset
      state on close() and only release it from its reset state on the next
      open().

      Note: when the unit is also used as system console it is always 'in use',
      so we cannot reset it on close().

      usb: patches for v4.3 merge window

      New support for Allwinne SoC on the MUSB driver has been added to the 
list of
      glue layers. MUSB also got support for building all DMA engines in one 
binary;
      this will be great for distros.

      DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely 
on
      tracing to debug DWC3. There was also a fix for memory corruption with 
EP0 when
      maxpacket size transfers are > 512 bytes.

      Robert's EP capabilities flags is making EP selection a lot simpler. UDCs 
are
      now required to set these flags up when adding endpoints to the framework.

      Other than these, we have the usual set of miscelaneous cleanups and minor
      fixes.

      batman-adv: Fix potential synchronization issues in mcast tvlv handler

      So far the mcast tvlv handler did not anticipate the processing of
      multiple incoming OGMs from the same originator at the same time. This
      can lead to various issues:

      * Broken refcounting: For instance two mcast handlers might both assume
        that an originator just got multicast capabilities and will together
        wrongly decrease mcast.num_disabled by two, potentially leading to
        an integer underflow.

      * Potential kernel panic on hlist_del_rcu(): Two mcast handlers might
        one after another try to do an
        hlist_del_rcu(&orig->mcast_want_all_*_node). The second one will
        cause memory corruption / crashes.
        (Reported by: Sven Eckelmann <sven@xxxxxxxxxxxxx>)

      Right in the beginning the code path makes assumptions about the current
      multicast related state of an originator and bases all updates on that. 
The
      easiest and least error prune way to fix the issues in this case is to
      serialize multiple mcast handler invocations with a spinlock.

      While the is only one standard mapping for 6 bpc and so the driver could

      regulator: core: Print at debug level on debugfs creation failure

      Failure to create a debugfs node is not an error, but we print a
      warning upon failure to create the node. Downgrade this to a
      debug printk so that we're quiet here. This allows multiple
      drivers to request a CPU's regulator so that CPUfreq and AVSish
      drivers can coexist.

      The downside of this approach is that whoever gets to debugfs first
      the others who come later to not have any debugfs attributes associated
      with them.

      spi: bcm2835: set up spi-mode before asserting cs-gpio

      When using reverse polarity for clock (spi-cpol) on a device
      the clock line gets altered after chip-select has been asserted
      resulting in an additional clock beat, which confuses hardware.

      This did not show when using native-CS, as the same register
      is used to control cs as well as polarity, so the changes came
      into effect at the same time. Unfortunately this is not true
      with gpio-cs.

      To avoid this situation this patch moves the setup of polarity
      (spi-cpol and spi-cpha) outside of the chip-select into
      prepare_message, which is run prior to asserting chip-select.

      Also fixes resetting 3-wire mode after use of rx-mode, so that
      a 3-Wire sequence TX, RX, TX works as well (right now it runs
      TX, RX, RX instead)

      libnvdimm, btt: write and validate parent_uuid

      When a BTT is instantiated on a namespace it must validate the namespace
      uuid matches the 'parent_uuid' stored in the btt superblock. This
      property enforces that changing the namespace UUID invalidates all
      former BTT instances on that storage. For "IO namespaces" that don't
      have a label or UUID, the parent_uuid is set to zero, and this
      validation is skipped. For such cases, old BTTs have to be invalidated
      by forcing the namespace to raw mode, and overwriting the BTT info
      blocks.

      As a result, don't check for validity of the BTT's UUID, and lbasize.
      The checksum in the BTT info block guarantees self-consistency, and when

      available to check against.

      arch: introduce memremap()

      Existing users of ioremap_cache() are mapping memory that is known in
      advance to not have i/o side effects.  These users are forced to cast
      away the __iomem annotation, or otherwise neglect to fix the sparse
      errors thrown when dereferencing pointers to this memory.  Provide
      memremap() as a non __iomem annotated ioremap_*() in the case when
      ioremap is otherwise a pointer to cacheable memory. Empirically,
      ioremap_<cacheable-type>() call sites are seeking memory-like semantics
      (e.g.  speculative reads, and prefetching permitted).

      memremap() is a break from the ioremap implementation pattern of adding
      a new memremap_<type>() for each mapping type and having silent
      compatibility fall backs.  Instead, the implementation defines flags
      that are passed to the central memremap() and if a mapping type is not
      supported by an arch memremap returns NULL.

      We introduce a memremap prototype as a trivial wrapper of
      ioremap_cache() and ioremap_wt().  Later, once all ioremap_cache() and
      ioremap_wt() usage has been removed from drivers we teach archs to
      implement arch_memremap() with the ability to strictly enforce the
      mapping type.

      The ssm4567 has sensing circuitry that can be used to monitor the current
      and voltage on the speaker amplifier output has well as the VBAT input.
      This data can be output over the I2S interface so it can be processed by a
      DSP or similar.

      This patch adds the sense capture output stream to the CODEC DAI as well 
as
      DAPM widgets that ensure that the sensing circuitry is powered up when the
      capture stream is active.

      perf trace: Move vfs_getname storage to per thread area

      We were storing the vfs_getname payload (i.e. ptr->string) into
      the trace wide storage area (struct trace), so that we could use the
      last payload when setting up the fd->pathname per thread tables, oops,
      not a good idea for multi cpu tracing sessions...

      Fix it by moving it to the per thread area (struct thread_trace).

      drm/i915: fix stolen bios_reserved checks

      I started digging this when I noticed that the BDW code was just
      reserving 1mb by coincidence since it was reading reserved fields.
      Then I noticed we didn't have any values set for SNB and earlier, and
      that the HSW sizes were wrong. After that, I noticed that the reserved
      area has a specific start, and may not exactly end where the stolen
      memory ends. I also noticed the base pointer can be zero. So I decided
      to just write a single patch fixing everything instead of 20 patches
      that would be much harder to review.

      This patch may solve random stolen memory corruption/problems on
      almost all platforms. Notice that since this is always dealing with
      the top of the stolen memory, the problems are not so easy to
      reproduce - especially since FBC is still disabled by default.

      One of the major differences of this patch is that we now look at both
      the size and base address. By only looking at the size we were
      assuming that the reserved area was always at the very top of
      stolen, which is not always true.

      After we merge the patch series that allows user space to allocate
      stolen memory we'll be able to write IGT tests that maybe catch the
      bugs fixed by this patch.

      v2:
        - s/BIOS reserved/stolen reserved/g (Chris)
        - Don't DRM_ERROR if we can't do anything about it (Chris)
        - Improve debug messages (Chris).
        - Use the gen7 version instead of gen6 on HSW. Tom found some
          documentation problems, so I think with gen7 we're on the safer
          side (Tom).

      connector is active, and ignore crtc->state->active when the
      connector is off.

      connectors_active is no longer checked, and will be removed later
      in this series together with dpms.

      Another check for !encoder->crtc is performed by check_encoder_state
      too, so it can be removed.

      Changes since v1:
      - Add commit message.
      - rename state to old_state.
      - Move deletion of mst_port check to mst patch.
      Changes since v2:
      - Fix a null pointer dereference on MST now hw readout is fixed.

      Fully remove the MST connector from the atomic state, and remove the
      early returns in check_*_state for MST connectors.

      With atomic the state can be made consistent all the time.

      Thanks to Sivakumar Thulasimani for the idea of using
      drm_atomic_helper_set_config.

      Changes since v1:

      mac80211: use DECLARE_EWMA

      Instead of using the out-of-line average calculation, use the new
      DECLARE_EWMA() macro to declare a signal EWMA, and use that.

      This actually *reduces* the code size slightly (on x86-64) while
      also reducing the station info size by 80 bytes.

      average: provide macro to create static EWMA

      Having the EWMA parameters stored in the runtime struct imposes
      memory requirements for the constant values that could just be
      inlined in the code. This particularly makes sense if there are
      a lot of such structs, for example in mac80211 in the station
      table where each station has a number of these in an array, and
      there can be many stations.

      Provide a macro DECLARE_EWMA() that declares the necessary struct
      and inline functions to access it with the parameters hard-coded;
      using this also means the user no longer needs to 'select AVERAGE'
      as it's entirely self-contained.

      In the mac80211 case, on x86-64, this actually slightly *reduces*
      code size, while also saving 80 bytes of runtime memory per sta.

      modsign: Handle signing key in source tree

      Since commit 1329e8cc69 ("modsign: Extract signing cert from
      CONFIG_MODULE_SIG_KEY if needed"), the build system has carefully coped
      with the signing key being specified as a relative path in either the
      source or or the build trees.

      However, the actual signing of modules has not worked if the filename
      is relative to the source tree.

      Fix that by moving the config_filename helper into scripts/Kbuild.include
      so that it can be used from elsewhere, and then using it in the top-level
      Makefile to find the signing key file.

      Kill the intermediate $(MODPUBKEY) and $(MODSECKEY) variables too, while
      we're at it. There's no need for them.

      modsign: Use if_changed rule for extracting cert from module signing key

      We couldn't use if_changed for this before, because it didn't live in
      the kernel/ directory so we couldn't add it to $(targets). It was easier
      just to leave it as it was.

      Now it's in the certs/ directory we can use if_changed, the same as we
      do for the trusted certificate list.

      Aside from making things consistent, this means we don't need to depend
      explicitly on the include/config/module/sig/key.h file. And we also get
      to automatically do the right thing and re-extract the cert if the user
      does odd things like using a relative filename and then playing silly
      buggers with adding/removing that file in both the source and object
      trees. We always favour the one in the object tree if it exists, and
      now we'll correctly re-extract the cert when it changes. Previously we'd
      *only* re-extract the cert if the config option changed, even if the
      actual file we're using did change.

      cxl: Allow the kernel to trust that an image won't change on PERST.

      Provide a kernel API and a sysfs entry which allow a user to specify
      that when a card is PERSTed, it's image will stay the same, allowing
      it to participate in EEH.

      cxl_reset is used to reflash the card. In that case, we cannot safely
      assert that the image will not change. Therefore, disallow cxl_reset
      if the flag is set.

      cxl: Don't remove AFUs/vPHBs in cxl_reset

      If the driver doesn't participate in EEH, the AFUs will be removed
      by cxl_remove, which will be invoked by EEH.

      If the driver does particpate in EEH, the vPHB needs to stick around
      so that the it can particpate.

      In both cases, we shouldn't remove the AFU/vPHB.

      cxl: Refactor AFU init/teardown

      As with an adapter, some aspects of initialisation are done only once
      in the lifetime of an AFU: for example, allocating memory, or setting
      up sysfs/debugfs files.

      However, we may want to be able to do some parts of the initialisation
      multiple times: for example, in error recovery we want to be able to
      tear down and then re-map IO memory and IRQs.

      Therefore, refactor AFU init/teardown as follows.

       - Create two new functions: 'cxl_configure_afu', and its pair
         'cxl_deconfigure_afu'. As with the adapter functions,
         these (de)configure resources that do not need to last the entire
         lifetime of the AFU.

       - Allocating and releasing memory remain the task of 'cxl_alloc_afu'
         and 'cxl_release_afu'.

       - Once-only functions that do not involve allocating/releasing memory
         stay in the overarching 'cxl_init_afu'/'cxl_remove_afu' pair.
         However, the task of picking an AFU mode and activating it has been
         broken out.

      cxl: Refactor adaptor init/teardown

      Some aspects of initialisation are done only once in the lifetime of
      an adapter: for example, allocating memory for the adapter,
      allocating the adapter number, or setting up sysfs/debugfs files.

      However, we may want to be able to do some parts of the
      initialisation multiple times: for example, in error recovery we
      want to be able to tear down and then re-map IO memory and IRQs.

      Therefore, refactor CXL init/teardown as follows.

       - Keep the overarching functions 'cxl_init_adapter' and its pair,
         'cxl_remove_adapter'.

       - Move all 'once only' allocation/freeing steps to the existing
         'cxl_alloc_adapter' function, and its pair 'cxl_release_adapter'
         (This involves moving allocation of the adapter number out of
         cxl_init_adapter.)

       - Create two new functions: 'cxl_configure_adapter', and its pair
         'cxl_deconfigure_adapter'. These two functions 'wire up' the
         hardware --- they (de)configure resources that do not need to
         last the entire lifetime of the adapter

      cxl: Clean up adapter MMIO unmap path.

      - MMIO pointer unmapping is guarded by a null pointer check.
         However, iounmap doesn't null the pointer, just invalidate it.
         Therefore, explicitly null the pointer after unmapping.

       - afu_desc_mmio also needs to be unmapped.

       - PCI regions are allocated in cxl_map_adapter_regs.
         Therefore they should be released in unmap, not elsewhere.

      cxl: Allocate and release the SPA with the AFU

      Previously the SPA was allocated and freed upon entering and leaving
      AFU-directed mode. This causes some issues for error recovery - contexts
      hold a pointer inside the SPA, and they may persist after the AFU has
      been detached.

      We would ideally like to allocate the SPA when the AFU is allocated, and
      release it until the AFU is released. However, we don't know how big the
      SPA needs to be until we read the AFU descriptor.

      Therefore, restructure the code:

       - Allocate the SPA only once, on the first attach.

       - Release the SPA only when the entire AFU is being released (not
         detached). Guard the release with a NULL check, so we don't free
         if it was never allocated (e.g. dedicated mode)

      cxl: Drop commands if the PCI channel is not in normal state

      If the PCI channel has gone down, don't attempt to poke the hardware.

      We need to guard every time cxl_whatever_(read|write) is called. This
      is because a call to those functions will dereference an offset into an
      mmio register, and the mmio mappings get invalidated in the EEH
      teardown.

      Check in the read/write functions in the header.
      We give them the same semantics as usual PCI operations:
       - a write to a channel that is down is ignored.
       - a read from a channel that is down returns all fs.

      Also, we try to access the MMIO space of a vPHB device as part of the
      PCI disable path. Because that's a read that bypasses most of our usual
      checks, we handle it explicitly.

      As far as user visible warnings go:
       - Check link state in file ops, return -EIO if down.
       - Be reasonably quiet if there's an error in a teardown path,
         or when we already know the hardware is going down.
       - Throw a big WARN if someone tries to start a CXL operation
         while the card is down. This gives a useful stacktrace for
         debugging whatever is doing that.

      powerpc/eeh: Probe after unbalanced kref check

      In the complete hotplug case, EEH PEs are supposed to be released
      and set to NULL. Normally, this is done by eeh_remove_device(),
      which is called from pcibios_release_device().

      However, if something is holding a kref to the device, it will not
      be released, and the PE will remain. eeh_add_device_late() has
      a check for this which will explictly destroy the PE in this case.

      This check in eeh_add_device_late() occurs after a call to
      eeh_ops->probe(). On PowerNV, probe is a pointer to pnv_eeh_probe(),
      which will exit without probing if there is an existing PE.

      This means that on PowerNV, devices with outstanding krefs will not
      be rediscovered by EEH correctly after a complete hotplug. This is
      affecting CXL (CAPI) devices in the field.

      Put the probe after the kref check so that the PE is destroyed
      and affected devices are correctly rediscovered by EEH.

      Merge branch 'vrf-lite'

      David Ahern says:

      ====================
      VRF-lite - v6

      In the context of internet scale routing a requirement that always comes
      up is the need to partition the available routing tables into disjoint
      routing planes. A specific use case is the multi-tenancy problem where
      each tenant has their own unique routing tables and in the very least
      need different default gateways.

      This patch allows the ability to create virtual router domains (aka VRFs
      (VRF-lite to be specific) in the linux packet forwarding stack. The main
      observation is that through the use of rules and socket binding to 
interfaces,
      all the facilities that we need are already present in the 
infrastructure. What
      is missing is a handle that identifies a routing domain and can be used to
      gather applicable rules/tables and uniqify neighbor selection. The scheme 
used
      needs to preserves the notions of ECMP, and general routing principles.

      This driver is a cross between functionality that the IPVLAN driver
      and the Team drivers provide where a device is created and packets
      into/out of the routing domain are shuttled through this device. The
      device is then used as a handle to identify the applicable rules. The
      VRF device is thus the layer3 equivalent of a vlan device.

      The very important point to note is that this is only a Layer3 concept
      so L2 tools (e.g., LLDP) do not need to be run in each VRF, processes can
      run in unaware mode or select a VRF to be talking through. Also the
      behavioral model is a generalized application of the familiar VRF-Lite
      model with some performance paths that need optimization. (Specifically
      the output route selector that Roopa, Robert, Thomas and EricB are
      currently discussing on the MPLS thread)

      High Level points
      =================
      1. Simple overlay driver (minimal changes to current stack)
         * uses the existing fib tables and fib rules infrastructure
      2. Modelled closely after the ipvlan driver
      3. Uses current API and infrastructure.
         * Applications can use SO_BINDTODEVICE or cmsg device indentifiers
           to pick VRF (ping, traceroute just work)
         * Standard IP Rules work, and since they are aggregated against the
           device, scale is manageable
      4. Completely orthogonal to Namespaces and only provides separation in
         the routing plane (and ARP)

      Given the topology above, the setup needed to get the basic VRF
      functions working would be

      Create the VRF devices and associate with a table
          ip link add vrf1 type vrf table 5
          ip link add vrf2 type vrf table 6

      Install the lookup rules that map table to VRF domain
          ip rule add pref 200 oif vrf1 lookup 5
          ip rule add pref 200 iif vrf1 lookup 5
          ip rule add pref 200 oif vrf2 lookup 6
          ip rule add pref 200 iif vrf2 lookup 6

          ip link set vrf1 up
          ip link set vrf2 up

      Enslave the routing member interfaces
          ip link set swp1 master vrf1
          ip link set swp2 master vrf1
          ip link set swp3 master vrf2
          ip link set swp4 master vrf2

      Connected and local routes are automatically moved from main and local
      tables to the VRF table.

      ping using VRF0 is simply
          ping -I vrf0 10.0.1.2

      Design Highlights
      =================
      If a device is enslaved to a VRF device (ie., associated with a VRF)
      then:
      1. Rx path
         The master device index is used as the iif for all lookups.

      2. Tx path
         Similarly, for Tx the VRF device oif is used in the flow to direct
         lookups to the table associated with the VRF via its rule. From there
         the FLOWI_FLAG_VRFSRC flag is used to indicate that the oif should
         not be used for FIB table lookups.

      3. Connected and local routes
         On link up for a device, connected and local routes are added to the
         table associated with the VRF device, rather than the local and main
         tables.

      4. Socket lookups
         Sockets operating in the VRF must be bound to the VRF device. As such
         socket lookups compare the VRF device index to sk_bound_dev_if.

      5. Neighbor entries
         Neighbor entries are not impacted by the VRF device. Entries are
         associated with a particular interface; the VRF association is indirect
         via the interface-to-VRF device enslavement.

      Version 6
      - addressed comments from DaveM

      - added patch to properly set oif in ip_send_unicast_reply. Needs to be
        set to VRF device for proper FIB lookup

      - added patch to handle IP fragments

      Version 5
      - dropped patch regarding socket lookups; no longer needed
        + removed vrf helpers no longer needed after this patch is dropped
      - removed dev_open and close operations
        + no need to reset vrf data on an ifdown and creates problems if a
          slave is deleted while the vrf interface is down (Thanks, Nikolay)
      - cleanups for sparse warnings
        + make C=2 is now clean for vrf driver

      Version 4
      - builds are clean with and without VRF device enabled (no, yes and 
module)
      - tightened the driver implementation
        + device add/delete, slave add/remove, and module unload are all clean
      - fixed RCU references
        + with RCU and lock debugging enabled changes are clean through the
          suite of tests
      - TX path uses custom dst, so patch refactoring rtable allocation is
        dropped along with the patch adding rt_nexthop helper
      - dropped the task patch that adds default bind to interface for sockets
        and the associated chvrf example command
        + the patches are a convenience for running unmodified code. They
          are not needed for the core functionality. Any application with
          support for SO_BINDTODEVICE works properly with this patch set.

      Version 3
      - addressed comments from first 2 RFCs with the exception of the name
        Nicolas: We will do the name conversion once we agree on what the
                 correct name should be (vrf, mrf or something else)

      -  packets flow through the VRF device in both directions allowing the
         following:
         - tcpdump -i vrf<n>
         - tc rules on vrf device
         - netfilter rules on vrf device

      TO-DO
      =====
      1. IPv6

      2. ipsec, xfrms
         - dst patch accepted into ipsec-next; will post VRF patch once merge 
happens

      3. listen filter to allow 1 socket to work with multiple VRF devices
         - i.e., bind to VRF's a, b, c only or NOT VRFs e, f, g

      Eric B:
        I have ipsec working with VRFs implemented using the VRF driver,
        including the worst case scenario of complete duplication in the
        networking config.

      Thanks to Nikolay for his many, many code reviews whipping the device
      driver into shape, and bug-Fixes and ideas from Hannes, Roopa Prabhu,

      This driver borrows heavily from IPvlan and teaming drivers.

      Routing domains (VRF-lite) are created by instantiating a VRF master
      device with an associated table and enslaving all routed interfaces that
      participate in the domain. As part of the enslavement, all connected
      routes for the enslaved devices are moved to the table associated with
      the VRF device. Outgoing sockets must bind to the VRF device to function.

      Standard FIB rules bind the VRF device to tables and regular fib rule
      processing is followed. Routed traffic through the box, is forwarded by
      using the VRF device as the IIF and following the IIF rule to a table
      that is mated with the VRF.

      Example:

         Create vrf 1:
           ip link add vrf1 type vrf table 5
           ip rule add iif vrf1 table 5
           ip rule add oif vrf1 table 5
           ip route add table 5 prohibit default
           ip link set vrf1 up

         Add interface to vrf 1:
           ip link set eth1 master vrf1

      net: frags: Add VRF device index to cache and lookup

      Fragmentation cache uses information from the IP header to reassemble
      packets. That information can be duplicated across VRFs -- same source
      and destination addresses, protocol and id. Handle fragmentation with
      VRFs by adding the VRF device index to entries in the cache and the
      lookup arg.

      net: Use passed in table for nexthop lookups

      If a user passes in a table for new routes use that table for nexthop
      lookups. Specifically, this solves the case where a connected route does
      not exist in the main table, but only another table and then a subsequent
      route is added with a next hop using the connected route. ie.,

      $ ip route ls
      default via 10.0.2.2 dev eth0
      10.0.2.0/24 dev eth0  proto kernel  scope link  src 10.0.2.15
      169.254.0.0/16 dev eth0  scope link  metric 1003
      192.168.56.0/24 dev eth1  proto kernel  scope link  src 192.168.56.51

      $ ip route ls table 10
      1.1.1.0/24 dev eth2  scope link

      Without this patch adding a nexthop route fails:

      $ ip route add table 10 2.2.2.0/24 via 1.1.1.10
      RTNETLINK answers: Network is unreachable

      With this patch the route is added successfully.

      net: dsa: mv88e6xxx: add hardware VLAN support

      This patchset brings support to access hardware VLAN entries in DSA and
      mv88e6xxx, through switchdev VLAN objects.

      In the following example, ports swp[0-2] belong to bridge br0, and ports
      swp[3-4] belong to bridge br1. Here's an example of what can be achieved
      after this patchset:

          # bridge vlan add dev swp1 vid 100 master
          # bridge vlan add dev swp2 vid 100 master
          # bridge vlan add dev swp3 vid 100 master
          # bridge vlan add dev swp4 vid 100 master
          # bridge vlan del dev swp1 vid 100 master

      The above commands correctly programmed hardware VLAN 100 for port swp2,
      while ports swp3 and swp4 use software VLAN 100, as shown with:

          # bridge vlan
          port  vlan ids
          swp0  None
          swp0
          swp1  None
          swp1
          swp2   100

          swp2   100

          swp3   100

          swp3
          swp4   100

          swp4
          br0   None
          br1   None

      Assuming that port 5 is the CPU port, the hardware VLAN table would
      contain the following data:

          VID  FID  SID  0  1  2  3  4  5  6
          100    8    0  x  x  t  x  x  t  x

      Where 'x' means excluded, and 't' means tagged.

      Also, adding an FDB entry to VLAN 100 for port swp2 like this:

          # bridge fdb add 3c:97:0e:11:6e:30 dev swp2 vlan 100

      Would result in the following example output:

          # bridge fdb
          # 01:00:5e:00:00:01 dev eth0 self permanent
          # 01:00:5e:00:00:01 dev eth1 self permanent
          # 00:50:d2:10:78:15 dev swp0 master br0 permanent
          # 00:50:d2:10:78:15 dev swp2 vlan 100 master br0 permanent
          # 3c:97:0e:11:6e:30 dev swp2 vlan 100 self static
          # 00:50:d2:10:78:15 dev swp3 master br1 permanent
          # 00:50:d2:10:78:15 dev swp3 vlan 100 master br1 permanent

      And the Address Translation Unit would contain:

          DB   T/P  Vec State Addr
          008  Port 004   e   3c:97:0e:11:6e:30

      net: ipv6 sysctl option to ignore routes when nexthop link is down

      Like the ipv4 patch with a similar title, this adds a sysctl to allow
      the user to change routing behavior based on whether or not the
      interface associated with the nexthop was an up or down link.  The
      default setting preserves the current behavior, but anyone that enables
      it will notice that nexthops on down interfaces will no longer be
      selected:

      net.ipv6.conf.all.ignore_routes_with_linkdown = 0
      net.ipv6.conf.default.ignore_routes_with_linkdown = 0
      net.ipv6.conf.lo.ignore_routes_with_linkdown = 0
      ...

      When the above sysctls are set, not only will link status be reported to
      userspace, but an indication that a nexthop is dead and will not be used
      is also reported.

      1000::/8 via 7000::2 dev p7p1  metric 1024 dead linkdown  pref medium
      1000::/8 via 8000::2 dev p8p1  metric 1024  pref medium
      7000::/8 dev p7p1  proto kernel  metric 256 dead linkdown  pref medium

      9000::/8 via 8000::2 dev p8p1  metric 2048  pref medium

      fe80::/64 dev p7p1  proto kernel  metric 256 dead linkdown  pref medium
      fe80::/64 dev p8p1  proto kernel  metric 256  pref medium

      This also adds devconf support and notification when sysctl values
      change.

      usb: chipidea: define stream mode disable for both roles

      The system bus and chipidea IP have different limitations for
      both host and device mode.
      For example, with below errata, we need to enable SDIS(Stream Disable
      Mode) at host mode. But we don't want it for device mode at the
      same system.

      TAR 9000378958
      Title: Non-Double Word Aligned Buffer Address Sometimes Causes Host to
      Hang on OUT Retry
      Impacted Configuration: Host mode, all transfer types
      Description:
      The host core operating in streaming mode may under run while sending
      the data packet of an OUT transaction. This under run can occur if
      there are unexpected system delays in fetching the remaining packet
      data from memory. The host forces a bad CRC on the packet, the device
      detects the error and discards the packet. The host then retries a Bulk,
      Interrupt, or Control transfer if an under run occurs according to the
      USB specification. During simulations, it was found that the host does
      not issue the retry of the failed bulk OUT. It does not issue any other
      transactions except SOF packets that have incorrect frame numbers.

      The second failure mode occurs if the under run occurs on an ISO OUT
      transaction and the next ISO transaction is a zero byte packet. The host
      does not issue any transactions (including SOFs). The device detects a
      Suspend condition, reverts to full speed, and waits for resume signaling.

      A third failure mode occurs when the host under runs on an ISO OUT and
      the next ISO in the schedule is an ISO OUT with two max packets of 1024
      bytes each. The host should issue MDATA for the first OUT followed by
      DATA1 for the second. However, it drops the MDATA transaction, and
      issues the DATA1 transaction.

      The system impact of this bug is the same regardless of the failure mode
      observed. The host core hangs, the ehci_ctrl state machine waits for the
      protocol engine to send the completion status for the corrupted
      transaction, which never occurs. No indication is sent to the host
      controller driver, no register bits change and no interrupts occur.
      Eventually the requesting application times out.

      Detailed internal behavior:
      The EHCI control state machine (ehci_ctrl) in the DMA block is responsible
      for parsing the schedules and initiating all transactions. The ehci_ctrl
      state machine passes the transaction details to the protocol block by
      writing the transaction information in to the TxFIFO. It then asserts
      the pe_hst_run_pkt signal to inform the host protocol state machine
      (pe_hst_state) that there is a packet in the TxFIFO.
      A tag of 0x0 indicates a start of packet with the data providing the
      following information:

      35:32 Tag
      31:30 Reserved
      29:23 Endpoint (lowest 4 bits)
      22:16 Address
      15:10 Reserved
      9:8 Endpoint speed
      7:6 Endpoint type
      5:6 Data Toggle
      3:0 PID
      The pe_hst_state reads the packet information and constructs the packet
      and issues it to the PHY interface.
      The ehci_ctrl state machine writes the start transaction information in
      to the TxFIFO as 0x03002910c for the OUT packet that had the under run
      error. However, it writes 0xC3002910C for the retry of the Out
      transaction, which is incorrect.
      The pe_hst_state enters a bus timeout state after sending the bad CRC
      for the packet that under ran. It then purges any data that was back
      filled in to the TxFIFO for the packet that under ran. The pe_hst_state
      machine stops purging the TxFIFO when it is empty or if it reads a
      location that has a tag of 0x0, indicating a start of packet command.

      The pe_hst_state reads 0xC3002910C and discards it as it does not decode
      to a start of packet command. It continues to purge the OUT data that
      has been pre-buffered for the OUT retry . The pe_hst_state detects the
      hst_packet_run signal and attempts to read the PID and address
      information from the TxFIFO. This location has packet data and so does
      not decode to a valid PID and so falls through to the PE_HST_SOF_LOAD
      state where the frame_num_counter is updated. The frame_num_counter
      is updated with the data in the TxFIFO. In this case, the data is
      incorrect as the ehci_ctrl state machine did not initiate the load.
      The hst_pe_state machine detects the SOF request signal and sends an
      SOF with the bad frame number. Meanwhile, the ehci_ctrl state machine
      waits indefinitely in the run_pkt state waiting for the completion
      status from pe_hst_state machine, which will never happen.

      The ISO failure case is similar except that there is no retry for ISO.
      The ehci_ctrl state machine moves to the next transfer in the periodic
      schedule. If the under run occurs on the last entry of the periodic
      list then it moves to the Async schedule.

      In the case of ISO OUT simulations, the next ISO is a zero byte OUT
      and again the start of packet command gets corrupted. The TxFIFO is
      empty when the hst_pe_state attempts to read the Address and PID
      information as the transaction is a zero byte packet. This results
      in the hst_pe_state machine staying in the GET_PID state, which means
      that it does not issue any transactions (including SOFs). The device
      detects a Suspend condition and reverts to full speed mode and waits
      for a Resume or Reset signal.

      The EHCI specification allows a Non-DoubleWord (32 bits) offset to
      be used as a current offset for Buffer Pointer Page 0 of the qTD.
      In Non-DoubleWord aligned cases, the core reads the packet data
      from the AHB memory, performs the alignment operation before writing
      it in to the TxFIFO as a 32 bit data word. An End Of Packet tag (EOP)
      is written to the TxFIFO after all the packet data has been written
      in to the TxFIFO. The alignment function is reset to Idle by the EOP
      tag. The corruption of the start of packet command arises because the
      packet buffer for the OUT transaction that under ran is not aligned
      to a DoubleWord, and hence no EOP tag is written to the TxFIFO. The
      alignment function is still active when the start packet information
      is written in to the TxFIFO for the retry of the bulk packet or for
      the next transaction in the case of an under run on an ISO. This
      results in the corruption of the start tag and the transaction
      information.

      Click for waveform showing the command 0x 0000300291 being written in
      to the TX FIFO for the Out that under ran.
      Click for waveform showing the command 0xC3002910C written to the
      TxFIFO instead of 0x 0000300291
      Versions affected: Versions 2.10a and previous versions
      How discovered: Customer simulation

      Workaround:
      1- The EHCI specification allows a non-DoubleWord offset to be used
      as a current offset for Buffer Pointer Page 0 of the qTD. However,
      if a DoubleWord offset is used then this issue does not arise.
      2- Use non streaming mode to eliminate under runs.

      Resolution:
      The fix involves changes to the traffic state machine in the
      vusb_hs_dma_traf block. The ehci_ctrl state machine updates the context
      information by encoding the transaction results on the
      hst_op_context_update signals at the end of a transaction. The signal
      hst_op_context_update is added to the traffic state machine, and the
      tx_fifo_under_ran_r signal is generated if the transaction results in
      an under run error. Click for waveform

      The traffic state machine then traverses to the do_eop states if the
      tx_fifo_under_ran error is asserted. Thus an EOP tag is written in to
      the TxFIFO as shown in this waveform .

      The EOP tag resets the align state machine to the Idle state ensuring
      that the next command written by the echi_ctrl state machine does not
      get corrupted.

      usb: chipidea: introduce ITC tuning interface

      ITC (Interrupt Threshold Control) is used to set the maximum rate at which
      the host/device controller will issue interrupts. The default value is 8 
(1ms)
      for it. EHCI core will modify it to 1, but device mode keeps it as default
      value.

      In some use cases like Android ADB, it only has one usb request for each
      direction, and maximum payload data is only 4KB, so the speed is 4MB/s
      at most, it needs controller to trigger interrupt as fast as possible
      to increase the speed. The USB performance will be better if the interrupt
      can be triggered faster.

      Reduce ITC value is benefit for USB performance, but the interrupt number
      is increased at the same time, it may increase cpu utilization too.
      Most of use case cares about performance, but some may care about
      cpu utilization, so, we leave a platform interface for user.
      We set ITC as 1 (1 micro-frame) as default value which is aligned
      with ehci core default value.

      usb: chipidea: add ttctrl.ttha control interface

      The register of ttctrl.ttha describes like below:
      - Internal TT Hub Address Representation
      - RW
      - Default = 0000000b
      This field is used to match against the Hub Address field in QH & siTD
      to determine if the packet is routed to the internal TT for directly
      attached FS/LS devices. If the Hub Address in the QH or siTD does not
      match this address then the packet will be broadcast on the High Speed
      ports destined for a downstream High Speed hub with the address in the 
QH/siTD.

      In silicon RTL, this entry only affects QH and siTD, and the hub.addr at
      both QH and siTD are 0 in ehci core for chipidea (with hcd->has_tt = 1).

      So, for QH, if the "usage_tt" flag at RTL is 0, set 
CI_HDRC_SET_NON_ZERO_TTHA
      will not affect QH (with non-hs device); for siTD, set this flag
      will change remaining space requirement for the last transaction from 1023
      bytes to 188 bytes, it can increase the number of transactions within one
      frame, ehci periodic schedule code will not queue the packet if the frame 
space
      is full, so it is safe to set this flag for siTD.

      With this flag, it can fix the problem Alan Stern reported below:
      http://www.spinics.net/lists/linux-usb/msg123125.html
      And may fix Michael Tessier's problem too.

http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next

      This serie of patches fix minor bugs around how driver sub-components are
      bind and planes z-ordering.
      The main part is about atomic support: using more atomic helpers allow us
      to simplify the code (~300 lines removed) and to ahve a better match 
between
      drm concepts (planes and crtc) and hardware split.

      rocker: hook ndo_neigh_destroy to cleanup neigh refs in driver

      Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops.  The
      driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is
      no event when the neigh is removed from the device (such as when the 
device
      goes admin down).  This patches hooks ndo_neigh_destroy so the driver can
      know when a neigh is removed from the device.  In response, the driver 
will
      purge the neigh entry from its internal tbl.

      I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if
      this ndo is vestigial or if there are out-of-tree users.  In any case, it
      does what I need here.  An alternative design would be to generate
      NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state 
to
      NUD_NONE so driver knows neigh entry is dead.

      ====================
      Enable smsc911x for use with ACPI

      This set of patches enables the front Ethernet port on the
      ARM Juno development platform when used with an ACPI enabled kernel.

      These patches covert the of_property* calls in the driver to the
      DT/ACPI agnostic device_property* calls, and add the arm hardware
      id to the acpi_match_table.

      To support the above changes I copied a couple routines from
      of_net into the properties.c file, and modified them to
      be ACPI/DT agnostic. I'm not 100% sure this is the correct location
      for these functions. But I think they are required to avoid having
      a dozen different implementations scattered across assorted Ethernet
      adapters that are being enabled to use ACPI properties.

      drivers: net: cpsw: add am335x errata workarround for interrutps

      As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and
      C0_RX_PEND interrupt outputs provide a single transmit interrupt
      that combines transmit channel interrupts TXPEND[7:0] and a
      single receive interrupt that combines receive channel interrupts
      RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are
      connected to the ARM Cortex-A8 interrupt controller (INTC) rather
      than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even
      though CPSW interrupt is cleared by writing appropriate values to
      EOI register the interrupt is not cleared in IRQ controller. So
      interrupt is still pending and CPU is struck in ISR, the
      workaround is to disable the interrupts in ARM irq controller.

      PCI: Allocate ATS struct during enumeration

      Previously, we allocated pci_ats structures when an IOMMU driver called
      pci_enable_ats().  An SR-IOV VF shares the STU setting with its PF, so 
when
      enabling ATS on the VF, we allocated a pci_ats struct for the PF if it
      didn't already have one.  We held the sriov->lock to serialize threads
      concurrently enabling ATS on several VFS so only one would allocate the PF
      pci_ats.

      Gregor reported a deadlock here:

        pci_enable_sriov
          sriov_enable
            virtfn_add
              mutex_lock(dev->sriov->lock)      # acquire sriov->lock
              pci_device_add
                device_add
                  BUS_NOTIFY_ADD_DEVICE notifier chain
                  iommu_bus_notifier
                    amd_iommu_add_device        # iommu_ops.add_device
                      init_iommu_group
                        iommu_group_get_for_dev
                          iommu_group_add_device
                            __iommu_attach_device
                              amd_iommu_attach_device  # iommu_ops.attach_device
                                attach_device
                                  pci_enable_ats
                                    mutex_lock(dev->sriov->lock) # deadlock

      There's no reason to delay allocating the pci_ats struct, and if we
      allocate it for each device at enumeration-time, there's no need for
      locking in pci_enable_ats().

      Allocate pci_ats struct during enumeration, when we initialize other
      capabilities.

      Note that this implementation requires ATS to be enabled on the PF first,
      before on any of the VFs because the PF controls the STU for all the VFs.

      md/raid5: split bio for chunk_aligned_read

      If a read request fits entirely in a chunk, it will be passed directly to 
the
      underlying device (providing it hasn't failed of course).  If it doesn't 
fit,
      the slightly less efficient path that uses the stripe_cache is used.
      Requests that get to the stripe cache are always completely split up as
      necessary.

      So with RAID5, ripping out the merge_bvec_fn doesn't cause it to stop 
work,
      but could cause it to take the less efficient path more often.

      All that is needed to manage this is for 'chunk_aligned_read' do some bio
      splitting, much like the RAID0 code does.

      block: remove split code in blkdev_issue_{discard,write_same}

      The split code in blkdev_issue_{discard,write_same} can go away
      now that any driver that cares does the split. We have to make
      sure bio size doesn't overflow.

      For discard, we set max discard sectors to (1<<31)>>9 to ensure
      it doesn't overflow bi_size and hopefully it is of the proper
      granularity as long as the granularity is a power of two.

      block: simplify bio_add_page()

      Since generic_make_request() can now handle arbitrary size bios, all we
      have to do is make sure the bvec array doesn't overflow.
      __bio_add_page() doesn't need to call ->merge_bvec_fn(), where
      we can get rid of unnecessary code paths.

      Removing the call to ->merge_bvec_fn() is also fine, as no driver that
      implements support for BLOCK_PC commands even has a ->merge_bvec_fn()
      method.

      block: make generic_make_request handle arbitrarily sized bios

      The way the block layer is currently written, it goes to great lengths
      to avoid having to split bios; upper layer code (such as bio_add_page())
      checks what the underlying device can handle and tries to always create
      bios that don't need to be split.

      But this approach becomes unwieldy and eventually breaks down with
      stacked devices and devices with dynamic limits, and it adds a lot of
      complexity. If the block layer could split bios as needed, we could
      eliminate a lot of complexity elsewhere - particularly in stacked
      drivers. Code that creates bios can then create whatever size bios are
      convenient, and more importantly stacked drivers don't have to deal with
      both their own bio size limitations and the limitations of the
      (potentially multiple) devices underneath them.  In the future this will
      let us delete merge_bvec_fn and a bunch of other code.

      We do this by adding calls to blk_queue_split() to the various
      make_request functions that need it - a few can already handle arbitrary
      size bios. Note that we add the call _after_ any call to
      blk_queue_bounce(); this means that blk_queue_split() and
      blk_recalc_rq_segments() don't need to be concerned with bouncing
      affecting segment merging.

      Some make_request_fn() callbacks were simple enough to audit and verify
      they don't need blk_queue_split() calls. The skipped ones are:

       * nfhd_make_request (arch/m68k/emu/nfblock.c)
       * axon_ram_make_request (arch/powerpc/sysdev/axonram.c)
       * simdisk_make_request (arch/xtensa/platforms/iss/simdisk.c)
       * brd_make_request (ramdisk - drivers/block/brd.c)
       * mtip_submit_request (drivers/block/mtip32xx/mtip32xx.c)
       * loop_make_request
       * null_queue_bio
       * bcache's make_request fns

      Some others are almost certainly safe to remove now, but will be left
      for future patches.

      ARM: EXYNOS: switch to using generic cpufreq driver for exynos4x12

      The new CPU clock type allows the use of generic CPUfreq driver.
      Switch Exynos4x12 to using generic cpufreq driver.

      Previously (when exynos-cpufreq driver was used with boost
      functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option
      (which enabled boost functionality) selected EXYNOS_THERMAL
      one. After switching Exynos4x12 platforms to use cpufreq-dt
      driver boost support is enabled in the cpufreq-dt driver
      itself (because there are turbo OPPs defined in the board's
      DTS file). However we still would like to allow enabling
      boost support only if thermal support is also enabled for
      Exynos platforms. To achieve this make ARCH_EXYNOS config
      option select THERMAL and EXYNOS_THERMAL ones.

      Please also note that the switch to use the generic cpufreq-dt
      driver fixes the minor issue present with the old code (support
      for 'boost' mode in the exynos-cpufreq driver was enabled for
      all supported SoCs even though 'boost' frequency was provided
      only for Exynos4x12 ones).

      perf tools: Support static linking with libdw

      The Fedora 22 version of libdw requires a couple of extra libraries to
      link. With a dynamic link the dependencies are pulled in automatically,
      but this doesn't work for static linking. Add the needed libraries
      explicitely to the feature probe and the Makefile.

      v2: Explicitly check for static linking and only add the dependencies
          when -static is set. This is to avoid regressions on Arnaldo's system.

      iommu/tegra-smmu: Parameterize number of TLB lines

      The number of TLB lines was increased from 16 on Tegra30 to 32 on
      Tegra114 and later. Parameterize the value so that the initial default
      can be set accordingly.

      On Tegra30, initializing the value to 32 would effectively disable the
      TLB and hence cause massive latencies for memory accesses translated
      through the SMMU. This is especially noticeable for isochronuous clients
      such as display, whose FIFOs would continuously underrun.

      ARM: tegra: cpuidle: implement cpuidle_state.enter_freeze()

      This callback is expected to do the same as enter() but it has to
      guarantee that interrupts aren't enabled at any point in its execution,
      as the tick is frozen.

      It will be called when the system goes to suspend-to-idle and will
      reduce power usage because CPUs won't be awaken for unnecessary IRQs.

      By setting the CPUIDLE_FLAG_TIMER_STOP flag, we can reuse the same code
      for both the enter() and enter_freeze() callbacks.

      memory: tegra: Add support for a variable-size client ID bitfield

      Recent versions of the Tegra MC hardware extend the size of the client
      ID bitfield in the MC_ERR_STATUS register by one bit.  While one could
      simply extend the bitfield for older hardware, that would allow data
      from reserved bits into the driver code, which is generally a bad idea
      on principle.  So this patch instead passes in the client ID mask from
      from the per-SoC MC data.

      There's no MC support for T210 (yet), but when that support winds up
      in the kernel, the appropriate soc->client_id_mask value for that chip
      will be 0xff.

      Based on an original patch by David Ung <davidu@xxxxxxxxxx>.

      iommu/tegra-smmu: Move flush_dcache to tegra-smmu.c

      Drivers should not be using __cpuc_* functions nor outer_cache_flush()
      directly.  This change partly cleans up tegra-smmu.c.

      The only difference between cache handling of the tegra variants is
      Denver, which omits the call to outer_cache_flush().  This is due to
      Denver being an ARM64 CPU, and the ARM64 architecture does not provide
      this function.  (This, in itself, is a good reason why these should not
      be used.)

      iommu/tegra-smmu: Fix page table lookup in unmap/iova_to_phys methods

      Fix the page table lookup in the unmap and iova_to_phys methods.
      Neither of these methods should allocate a page table; a missing page
      table should be treated the same as no mapping present.

      More importantly, using as_get_pte() for an IOVA corresponding with a
      non-present page table entry increments the use-count for the page
      table, on the assumption that the caller of as_get_pte() is going to
      setup a mapping.  This is an incorrect assumption.

      Fix both of these bugs by providing a separate helper which only looks
      up the page table, but never allocates it.  This is akin to pte_offset()
      for CPU page tables.

      iommu/tegra-smmu: Fix unmap() method

      The Tegra SMMU unmap path has several problems:
      1. as_pte_put() can perform a write-after-free
      2. tegra_smmu_unmap() can perform cache maintanence on a page we have
         just freed.
      3. when a page table is unmapped, there is no CPU cache maintanence of
         the write clearing the page directory entry, nor is there any
         maintanence of the IOMMU to ensure that it sees the page table has
         gone.

      Fix this by getting rid of as_pte_put(), and instead coding the PTE
      unmap separately from the PDE unmap, placing the PDE unmap after the
      PTE unmap has been completed.

      iommu/tegra-smmu: Fix iova_to_phys() method

      iova_to_phys() has several problems:
      (a) iova_to_phys() is supposed to return 0 if there is no entry present
          for the iova.
      (b) if as_get_pte() fails, we oops the kernel by dereferencing a NULL
          pointer.  Really, we should not even be trying to allocate a page
          table at all, but should only be returning the presence of the 2nd
          level page table.  This will be fixed in a subsequent patch.

      Treat both of these conditions as "no mapping" conditions.

      gpio/mxc: mask gpio interrupts in suspend

      Currently in the FSL platform all GPIO interrupts in a bank are muxed
      into two GPIO lines to the GPC interrupt controller. In each GPIO bank
      GPIOs 0-15 are OR'ed into one GPC interrupt controller interrupt and 16-31
      are OR'ed into another. With the current code, if any of the 0-15 or
      16-31 interrupts are marked as wakeup capable, all interrupts belonging
      to that sub-bank (either 0-15 or 16-31) will wake up the device. This is
      because interrupts are only being masked at the interrupt controller
      and not at the GPIO controller.

      This patch allows masking of GPIO interrupts at the GPIO controller during
      suspend if they have not been labeled wakeup capable. This patch uses
      preexisting IRQCHIP_MASK_ON_SUSPEND flag while initializing the GPIO
      interrupts to get the desired behavior.

      alloc_orinocodev() would allocate the wiphy entry, but it would only get
      registered much later in orinoco_init(). If something failed in the init
      process inbetween the call to alloc_orinocodev() and the completion
      of orinoco_init(), the drivers would end up calling wiphy_unregister()
      with a NULL pointer causing beautiful OOPS fireworks.

      Explicitly call wiphy_unregister() instead in the right places.

      mwifiex: claim sdio bus while downloading the firmware

      Our 8887 A2 chip can have separate firmware images for
      bluetooth and WLAN. We observed an issue during parallel
      downloading of these images by btmrvl and mwifiex drivers.

      This patch claims sdio bus before starting of the firmware
      download in mwifiex and releases it after completion to
      fix the problem.

      rtlwifi: rtl8192c-common: Fix two typos

      In this driver, two variables are masked by one quantity, and then tested
      against a second number with more bits that the mask. Accordingly, the
      test always fails. To minimize the possibility of such typos, a symbolic
      definition of the mask is created and used.

      The separate load and mask operations are also combined into a single
      statement.

      Commit e996db69833a (rtlwifi: rtl8192c: Add init codes for "fw_version"
      and "fw_subversion") added initialization for fw_version, but failed to
      note that the variable in the firmware header is little-endian. The
      following Sparse warning results:

        CHECK   drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
      drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: 
incorrect type in assignment (different base types)

      drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36:    got 
restricted __le16 [usertype] version

      When fixing this problem, I noticed that several of the drivers contain
      nearly identical copies of the firmware header struct, and that only the 
one
      used in rtl8192c{e,u} had correct endian notation. The struct has been
      moved into a common header, and the other drivers will be fixed in
      subsequant patches.

      ASoC: dapm: Consolidate input and output path handling

      After the recent cleanups and generalizations of the DAPM algorithm the
      handling of input and output paths is now fully symmetric. This means by
      making some slight changes to the data structure and using arrays with one
      entry for each direction, rather than separate fields, it is possible to
      create a generic implementation that is capable of handling both input and
      output paths.

      Unfortunately this generalization significantly increases the code size on
      the hot path of is_connected_{input,output}_ep() and
      dapm_widget_invalidate_{input,output}_paths(), which has a negative impact
      on the overall performance. The inner loops of those functions are quite
      small and the generic implementation adds extra pointer arithmetic in a 
few
      places.

      Testing on ARM shows that the combined code size of the specialized
      functions is about 50% larger than the generalized function in relative
      numbers. But in absolute numbers its less than 200 bytes, which is still
      quite small. On the other hand the generalized function increases the
      execution time of dapm_power_one_widget() by 30%. Given that this function
      is one of the most often called functions of the DAPM framework the
      trade-off of getting better performance at expense of generating slightly
      larger code at seems to be worth it.

      To avoid this still keep two versions of these functions around, one for
      input and one for output. But have a generic implementation of the
      algorithm which gets inlined by those two versions. And then let the
      compiler take care of optimizing it and removing he extra instructions.

      This still reduces the source code size as well as the makes making 
changes
      to the implementation more straight forward since the same change does no
      longer need to be done in two separate places. Also on the slow paths we
      can use a generic implementations that handle both input and output paths.

      ath10k: don't remove peer that doesn't exist

      If peer creation failed during offchannel Tx the
      driver attempted to delete the peer nonetheless.
      This caused the ar->num_peers counter to be
      incorrectly decremented. This subsequently could
      cause the counter to drop below 0 and also
      eventually lead to firmware crash because host
      would think there are less peer entries created in
      firmware then there really were.

      ath10k: reject 11b tx fragmentation configuration

      Even though there's a WMI enum for fragmentation
      threshold no known firmware actually implements
      it. Moreover it is not possible to rely frame
      fragmentation to mac80211 because firmware clears
      the "more fragments" bit in frame control making
      it impossible for remote devices to reassemble
      frames.

      Hence implement a dummy callback just to say
      fragmentation isn't supported. This effectively
      prevents mac80211 from doing frame fragmentation
      in software.

      This fixes Tx becoming broken after setting
      fragmentation threshold.

      gpio: brcmstb: support wakeup from S5 cold boot

      For wake from S5, we need to:
      - register a reboot handler
      - set wakeup capability before requesting IRQ so wakeup count is
        incremented
      - mask all GPIO IRQs and clear any pending interrupts during driver
        probe to since no driver will yet be registered to handle any IRQs
        carried over from boot at that time, and it's possible that the
        booted kernel does not request the same IRQ anyway.

      This means that /sys/.../power/wakeup_count is valid at boot time, and
      we can properly account for S5 wakeup stats. e.g.:

        ### After waking from S5 from a GPIO key
        # cat /sys/bus/platform/drivers/brcmstb-gpio/f04172c0.gpio/power/wakeup
        enabled
        # cat 
/sys/bus/platform/drivers/brcmstb-gpio/f04172c0.gpio/power/wakeup_count

      gpio: brcmstb: Add interrupt and wakeup source support

      Uses the gpiolib irqchip helpers.  For this to work, the irq setup
      function is called once per bank instead of once per device.  Note
      that all known uses of this block have a BCM7120 L2 interrupt
      controller as a parent.  Supports interrupts for all GPIOs.

      In the IRQ handler, we check for raised IRQs for invalid GPIOs and
      warn (ratelimited) if they're encountered.

      Also, several drivers (e.g. gpio-keys) allow for GPIOs to be
      configured as wakeup sources, and this GPIO controller supports that
      through a separate interrupt path.

      The de-facto standard DT property "wakeup-source" is checked, since
      that indicates whether the GPIO controller hardware can wake.  Uses
      the IRQCHIP_MASK_ON_SUSPEND irq_chip flag because UPG GIO doesn't have
      any of its own wakeup source configuration.

      Aside regarding gpiolib irqchip helpers: It wasn't obvious (to me)
      that you can have multiple chained irqchips and associated IRQ domains
      for a single parent IRQ, and as long as the xlate function is written
      correctly, a GPIO IRQ request end up checking the correct domain and
      will get associated with the correct IRQ.  What helps make this clear
      is to read
        drivers/gpio/gpiolib-of.c:
         - of_gpiochip_find_and_xlate()
         - of_get_named_gpiod_flags()
        drivers/gpio/gpiolib.c:
         - gpiochip_find()

      Some more devicetree changes, including usbphy support for the

      Two more veyron-devices - namely Speedy and Minnie and a fix for

      One slightly more interesting fix is the blocking of the last
      16MB of memory on 4GB rk3288 devices. The rk3288 cannot use this
      area for dma operations, so things like the mmc or usb controllers
      regularly fail when trying to read data. This solution mimicks the
      solution from the ChromeOS kernel, who also do not seem to have
      found a better solution yet. Here it only moves to the devicetree.
      As this issue is also present on the arm64 rk3368, any future
      better solution to this problem would need to describe this in
      the devicetree as well and could then remove this block.

      KVM: s390: fix and feature for kvm/next (4.3)

      1. error handling for irq routes
      2. Gracefully handle STP time changes
         s390 supports a protocol for syncing different systems via the stp
         protocol that will steer the TOD clocks to keep all participating
         clocks below the round trip time between the system. In case of
         specific out of sync event Linux can opt-in to accept sync checks.
         This will result in non-monotonic jumps of the TOD clock, which
         Linux will correct via time offsets to keep the wall clock time
         monotonic. Now: KVM guests also base their time on the host TOD,
         so we need to fixup the offset for them as well.

      x86/mce: Reenable CMCI banks when swiching back to interrupt mode

      Zhang Liguang reported the following issue:

      1) System detects a CMCI storm on the current CPU.

      2) Kernel disables the CMCI interrupt on banks owned by the
         current CPU and switches to poll mode

      3) After the CMCI storm subsides, kernel switches back to
         interrupt mode

      4) We expect the system to reenable the CMCI interrupt on banks
         owned by the current CPU

         mce_intel_adjust_timer
         |-> cmci_reenable
             |-> cmci_discover     # owned banks are ignored here

        static void cmci_discover(int banks)
        ...
        for (i = 0; i < banks; i++) {
                ...
                if (test_bit(i, owned)) # ownd banks is ignore here
                        continue;

      So convert cmci_storm_disable_banks() to
      cmci_toggle_interrupt_mode() which controls whether to enable or
      disable CMCI interrupts with its argument.

      NB: We cannot clear the owned bit because the banks won't be
      polled, otherwise. See:

        27f6c573e0f7 ("x86, CMCI: Add proper detection of end of CMCI storms")

      for more info.

      x86/mce: Provide a lockless memory pool to save error records

      printk() is not safe to use in MCE context. Add a lockless
      memory allocator pool to save error records in MCE context.
      Those records will be issued later, in a printk-safe context.
      The idea is inspired by the APEI/GHES driver.

      We're very conservative and allocate only two pages for it but
      since we're going to use those pages throughout the system's
      lifetime, we allocate them statically to avoid early boot time
      allocation woes.

      memory: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also set IRQ_NOPROBE and this has been maintained although it is not
      clear that is really needed. There appears to be a great deal of blind
      copy and paste of this code.

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Allow selecting the type of callchains per event, including disabling
          callchains in all but one entry in an event list, to save space, and 
also
          to ask for the callchains collected in one event to be used in other
          events. (Kan Liang)

        - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de 
Melo)
          - A bunch more translate file/pathnames from pointers to strings.
          - Convert numbers to strings for the 'keyctl' syscall 'option' arg.
          - Add missing 'clockid' entries.

        - Fix 'perf probe -L sys_*' as it was not showing all the source code 
for
          syscall functions in the kernel. (Masami Hiramatsu)

        - Make ESC unzoom as well in the hists browser, i.e. in 'report' and 
'top',
          as we're considering repurposing the right and left arrow keys to use 
in
          horizontal scrolling, i.e. leave just ESC to be used for what <- works
          now, and ENTER for what -> does (they are already aliases for ages).
          (Arnaldo Carvalho de Melo)

      Infrastructure fixes:

        - Check for SRCLINE_UNKNOWN case in "srcfile" processing (Andi Kleen)

        - Wrap the slsmg_{printf,write_nstring} slang functions behind 
ui_browser, so
          that we can make the ui_browser based browsers (annotate, menus, 
hists, etc) UI
          library agnostic and usable with multiple backends (slang now, GTK+ 
and others
          in the future, maybe) (Arnaldo Carvalho de Melo)

      jump_label/x86: Work around asm build bug on older/backported GCCs

      Boris reported that gcc version 4.4.4 20100503 (Red Hat
      4.4.4-2) fails to build linux-next kernels that have
      this fresh commit via the locking tree:

        11276d5306b8 ("locking/static_keys: Add a new static_key interface")

      The problem appears to be that even though @key and @branch are
      compile time constants, it doesn't see the following expression
      as an immediate value:

         &((char *)key)[branch]

      More recent GCCs don't appear to have this problem.

      In particular, Red Hat backported the 'asm goto' feature into 4.4,
      'normal' 4.4 compilers will not have this feature and thus not
      run into this asm.

      The workaround is to supply both values to the asm as immediates
      and do the addition in asm.

      net: ipv4: increase dhcp inter device timeout

      When a system has multiple ethernet devices and during DHCP
      request (for using NFS), the system waits only for HZ/2 which is
      500mS before switching to another interface for DHCP.

      There are some routers (Ex: Trendnet routers) which responds to
      DHCP request at about 560mS. When the system has only one
      ethernet interface there is no issue as the timeout is 2S and the
      dev xid doesn't changes and only retries.

      But when the system has multiple Ethernet like DRA74x with CPSW
      in dual EMAC mode, the DHCP response is dropped as the dev xid
      changes while shifting to the next device. So changing inter
      device timeout to HZ (which is 1S).

      bpf: fix build warnings and add function read_trace_pipe()

      There are two improvements in this patch:
       1. Fix the build warnings;
       2. Add function read_trace_pipe() to print the result on
          the screen;

      Before this patch, we can get the result through /sys/kernel/de
      bug/tracing/trace_pipe and get nothing on the screen.
      By applying this patch, the result can be printed on the screen.

      Comment in struct Scsi_Host says that drivers are not supposed to access

      so we can just use shost_for_each_device().

      storvsc: be more picky about scmnd->sc_data_direction

      Under the 'default' case in scmnd->sc_data_direction we have 3 options:
      - DMA_NONE which we handle correctly.
      - DMA_BIDIRECTIONAL which is never supposed to be set by SCSI stack.
      - Garbage value.

      Do WARN() and return -EINVAL in the last two cases. virtio_scsi does
      BUG_ON() here but it looks like an overkill.

      hv_netvsc: Implement set_channels ethtool op

      This enables the use of ethtool --set-channels devname combined N to
      change the number of vRSS queues. Separate rx, tx, and other parameters
      are not supported. The maximum is rsscap.num_recv_que. It passes the
      given value to rndis_filter_device_add through the device_info->num_chn
      field.

      If the procedure fails, it attempts to recover to the prior state. If
      the recovery fails, it logs an error and aborts.

      Current num_chn is saved and restored when changing the MTU.

      Uses device_info->num_chn to pass user provided number of vRSS

      Always initialize struct device_info to 0, otherwise not all its fields

      fs: Set the size of empty dirs to 0.

      Before the make_empty_dir_inode calls were introduce into proc, sysfs,
      and sysctl those directories when stated reported an i_size of 0.
      make_empty_dir_inode started reporting an i_size of 2.  At least one
      userspace application depended on stat returning i_size of 0.  So
      modify make_empty_dir_inode to cause an i_size of 0 to be reported for
      these directories.

      dm snapshot: don't invalidate on-disk image on snapshot write overflow

      When the snapshot overflows because of a write to the origin, the on-disk
      image has to be invalidated.  However, when the snapshot overflows because
      of a write to the snapshot, the on-disk image doesn't have to be
      invalidated.  Change the behavior so that the on-disk image is not
      invalidated in this case.

      When the snapshot overflows, the variable snapshot_overflowed is set.
      All writes to the snapshot are disallowed to minimize filesystem
      corruption - this condition is cleared when the snapshot is deactivated
      and activated.

      The user can extend the overflowed snapshot, deactivate and activate it
      again, run fsck (if journaling filesystem is not used) mount it and
      recover the data.

      userns,pidns: Force thread group sharing, not signal handler sharing.

      The code that places signals in signal queues computes the uids, gids,
      and pids at the time the signals are enqueued.  Which means that tasks
      that share signal queues must be in the same pid and user namespaces.

      Sharing signal handlers is fine, but bizarre.

      So make the code in fork and userns_install clearer by only testing
      for what is functionally necessary.

      Also update the comment in unshare about unsharing a user namespace to
      be a little more explicit and make a little more sense.

      unshare: Unsharing a thread does not require unsharing a vm

      In the logic in the initial commit of unshare made creating a new
      thread group for a process, contingent upon creating a new memory
      address space for that process.  That is wrong.  Two separate
      processes in different thread groups can share a memory address space
      and clone allows creation of such proceses.

      This is significant because it was observed that mm_users > 1 does not
      mean that a process is multi-threaded, as reading /proc/PID/maps
      temporarily increments mm_users, which allows other processes to
      (accidentally) interfere with unshare() calls.

      Correct the check in check_unshare_flags() to test for
      !thread_group_empty() for CLONE_THREAD, CLONE_SIGHAND, and CLONE_VM.
      For sighand->count > 1 for CLONE_SIGHAND and CLONE_VM.
      For !current_is_single_threaded instead of mm_users > 1 for CLONE_VM.

      By using the correct checks in unshare this removes the possibility of
      an accidental denial of service attack.

      Additionally using the correct checks in unshare ensures that only an
      explicit unshare(CLONE_VM) can possibly trigger the slow path of
      current_is_single_threaded().  As an explict unshare(CLONE_VM) is
      pointless it is not expected there are many applications that make
      that call.

      Jonathan writes:

      Second set of new device support, features and cleanup for the 4.3 cycle.
      Take 2 also includes a fix set that was too late for the 4.2 cycle.

      As we had a lot of tools and docs work in this set, I have broken those
      out into their own categories in this description.

      Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
      * Poll functions for both event chardev and the buffer one were returning
        negative error codes (via a positive value).
      * A recent change to lsiio adding some error handling that was wrong and
        stopped the tool working.
      * bmg160 was missing some dependencies in Kconfig
      * berlin2-adc had a misshandled register (wrote a value rather than a 
bitmap)

      New device support
      * TI opt3001 light sensor
      * TXC PA12 ALS and proximity sensor.
      * mcp3301 ADC support (in mcp320x driver)
      * ST lsm303agr accelerometer and magnetometer drivers (plus some 
st-sensors
        common support to allow different WHOAMI register addresses, devices 
with
        fixed scale and allow interrupt equiped magnetometers).
      * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
      * ADIS16266 gyro (in the adis16260 driver)
      * ADIS16137 gyro (in the adis16136 driver)

      New functionality
      * mmc35240 DT bindings.
      * Inverse unit conversion macros to aid handing of values written to sysfs
        attributes.

      Core cleanup
      * Forward declaration of struct iio_trigger to avoid a compile warning.

      Driver cleanup / fixes
      * mxs-lradc
        - Clarify which parts are supported.
        - Fix spelling erorrs.
        - Missing/extra includes
        - reorder includes
        - add datasheet name listings for all usable channels (to allow them
          to be bound by name from consumer drivers)
      * acpi-als - add some function prefixes as per general iio style.
      * bmc150_magn - replace a magic value with the existing define.
      * vf610 - determine possible sample frequencies taking into account the
        electrical characteristics (defining a minimum sample time)
      * dht11
        - whitespace
        - additional docs
        - avoid mulitple assignments in one line
        - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
          previously used for timing.
      * Fix all drivers that consider 0 a valid IRQ for historical reasons.
      * Export I2C module alias info where previously missing (to allow 
autoprobing)
      * Export OF module alias info where previously missing.
      * mmc35240 - switch some variables into arrays to improve readability.
      * mlx90614 - define some magic numbers for readability.
      * bmc150_magn
        - expand area locked by a mutex to cover all the use of the
          data->buffer.
        - use descriptive naming for a mask instead of a magic value.
      * berin2-adc
        - pass up an error code rather that a generic error
        - constify the iio_chan_spec
        - some other little tidy ups.
      * stk8312
        - fix a dependency on triggered buffers in kconfig
        - add a check for invalid attribute values
        - improve error handling by returning error codes where possible and
          return immediately where relevant
        - rework macro defs to use GENMASK etc
        - change some variable types to reduce unnecessary casting
        - clean up code style
        - drop a local buffer copy for bulk reads and use the one in 
data->buffer
           instead.
      * adis16400 - the adis16448 gyroscope scale was wrong.
      * adis16480 - some more wrong scales for various parts.
      * adis16300 - has an undocumented product id and serial number registers 
so
        use them.
      * iio_simple_dummy - fix some wrong code indentation.
      * bmc150-accel - use the chip ID to detect the chip present rather than
        verifying the expected part was there.  This was in response to a wrong
        ACPI entry on the WinBook TW100.
      * mma8452
        - fix _get_hp_filter_index
        - drop a double include
        - pass up an error code rather than rewriting it
        - range check input values to attribute writes
        - register defs tidy up using GENMASK and reordering them to be easier 
to
          follow.
        - various coding style cleanups
        - put the Kconfig entry in the write place (alphabetically).

      Tools related
      * Tools cleanup - drop an explicity NULL comparison, some unnecessary 
braces,
        use the ARRAY_SIZE macro, send error messages to stderr instead of 
dropping
        them in the middle of normal output.
      * Fix tools to allow that scale and offset attributes are optional.
      * More tools fixes including allowing true 32bit data (previously an 
overflow
        prevented more than 31bits)
      * Drop a stray header guard that ended up in a c file.
      * Make calc_digits static as it isn't exported or in the header.
      * Set ci_array pointer to NULL after free as a protection against non safe
        usage of the tools core code.  Also convert a double pointer to a single
        one as the extra level of indirection was unnecessary.

      Docs
      * DocBook introduction by Daniel Baluta.  Glad we are beginning to
        draw together some more introductory docs to suplement the various
        tools / examples.
      * Drop bytes_per_datum sysfs attribute docs as it no longer exists.
      * A whole load of missing / fixing of kernel-doc for the core of IIO.
      * Document the trigger name sysfs attribute in the ABI docs.
      * Minor typos in the ABI docs related to power down modes.

      hwmon: (ltc2978) Add support for LTC3882

      LTC3882 is mostly compatible with LTC3880. Major differences are that it
      does not measure the input current, and it no longer supports LTC's legacy
      mechanism to identify the chip.

      hwmon: (ltc2978) Move code to read chip ID into separate function

      Verifying the chip type is getting more complicated with new chips,
      since not all chips support the same mechanism to read the chip type.
      Move the code into a separate function to simplify adding support for
      those chips.

      NFSv4: don't set SETATTR for O_RDONLY|O_EXCL

      It is unusual to combine the open flags O_RDONLY and O_EXCL, but
      it appears that libre-office does just that.

      [pid  3250] stat("/home/USER/.config", {st_mode=S_IFDIR|0700, 
st_size=8192, ...}) = 0
      [pid  3250] 
open("/home/USER/.config/libreoffice/4-suse/user/extensions/buildid", 
O_RDONLY|O_EXCL <unfinished ...>

      NFSv4 takes O_EXCL as a sign that a setattr command should be sent,
      probably to reset the timestamps.

      When it was an O_RDONLY open, the SETATTR command does not
      identify any actual attributes to change.
      If no delegation was provided to the open, the SETATTR uses the
      all-zeros stateid and the request is accepted (at least by the
      Linux NFS server - no harm, no foul).

      If a read-delegation was provided, this is used in the SETATTR
      request, and a Netapp filer will justifiably claim
      NFS4ERR_BAD_STATEID, which the Linux client takes as a sign
      to retry - indefinitely.

      So only treat O_EXCL specially if O_CREAT was also given.

      sunrpc: increase UNX_MAXNODENAME from 32 to __NEW_UTS_LEN bytes

      The current limit of 32 bytes artificially limits the name string that
      we end up stuffing into NFSv4.x client ID blobs. If you have multiple
      hosts with long hostnames that only differ near the end, then this can
      cause NFSv4 client ID collisions.

      Linux nodenames are actually limited to __NEW_UTS_LEN bytes (64), so use
      that as the limit instead. Also, use XDR_QUADLEN to specify the slack
      length, just for clarity and in case someone in the future changes this
      to something not evenly divisible by 4.

      qla2xxx: prevent board_disable from running during EEH

      Commit f3ddac1918fe963bcbf8d407a3a3c0881b47248b ("[SCSI] qla2xxx:
      Disable adapter when we encounter a PCI disconnect.") has introduced a
      code that disables the board, releasing some resources, when reading
      0xffffffff.

      In case this happens when there is an EEH, this read will trigger EEH
      detection and set PCI channel offline. EEH will be able to recover the
      card from this state by doing a reset, so it's a better option than
      simply disabling the card.

      Since eeh_check_failure will mark the channel as offline before
      returning the read value, in case there really was an EEH, we can simply
      check for pci_channel_offline, preventing the board_disable code from
      running if it's true.

      Without this patch, EEH code will try to access those same resources
      that board_disable will try to free. This race can cause EEH recovery to
      fail.

      drm/vmwgfx: Fix crash when unloading vmwgfx v2

      This patch fixes two issues.  One, when a surface is a proxy for a DMA
      buffer, it holds an extra reference that needs to be cleared.

      Two, when fbdev is enabled, we need to unpin the framebuffer before
      unloading the driver.  This is done by a call to vmw_fb_off().

      v2
      Moved unreferencing surface to from vmw_framebuffer_surface_destroy()
      to vmw_kms_new_framebuffer()

      Added "struct vmw_framebuffer *vfb = NULL;" to silence a compiler
      warning.

      Removed error checking after calling vmw_surface/dmabuf_reference()

      drm/vmwgfx: Fixed topology boundary checking for Screen Targets

      For a Screen Target capable display device, the display topology is
      limited by SVGA_REG_MAX_PRIMARY_BOUNDING_BOX_MEM.  Two values are
      checked against this limit:
        1.  Size of the bounding box enclosing all the displays, and
        2.  Size of the total number of displays, e.g. framebuffers

      The limitations above mean we do not have exact max width and
      height for the topology.  The best current option is to set those to
      the maximum texture width/height.

      perf probe: Fix to show lines of sys_ functions correctly

      "perf probe --lines sys_poll" shows only the first line of sys_poll,
      because the SYSCALL_DEFINE macro:

        ----
        SYSCALL_DEFINE*(foo,...)
        {
          body;
        }
        ----

        is expanded as below (on debuginfo)

        ----

        static inline int SYSC_foo(...)
        {
          body;
        }
        int SyS_foo(...) <- is an alias of sys_foo.
        {
          return SYSC_foo(...);
        }
        ----

      So, "perf probe --lines sys_foo" decodes SyS_foo function and it also 
skips
      inlined functions(SYSC_foo) inside the target function because those 
functions
      are usually defined somewhere else.

      To fix this issue, this fix checks whether the inlined function is 
defined at
      the same point of the target function, and if so, it doesn't skip the 
inline
      function.

      sign-file: Document dependency on OpenSSL devel libraries

      The revised sign-file program is no longer a script that wraps the openssl
      program, but now rather a program that makes use of OpenSSL's crypto
      library.  This means that to build the sign-file program, the kernel build
      process now has a dependency on the OpenSSL development packages in
      addition to OpenSSL itself.

      Document this in Kconfig and in module-signing.txt.

      PKCS#7: Appropriately restrict authenticated attributes and content type

      A PKCS#7 or CMS message can have per-signature authenticated attributes
      that are digested as a lump and signed by the authorising key for that
      signature.  If such attributes exist, the content digest isn't itself
      signed, but rather it is included in a special authattr which then
      contributes to the signature.

      Further, we already require the master message content type to be
      pkcs7_signedData - but there's also a separate content type for the data
      itself within the SignedData object and this must be repeated inside the
      authattrs for each signer [RFC2315 9.2, RFC5652 11.1].

      We should really validate the authattrs if they exist or forbid them
      entirely as appropriate.  To this end:

       (1) Alter the PKCS#7 parser to reject any message that has more than one
           signature where at least one signature has authattrs and at least one
           that does not.

       (2) Validate authattrs if they are present and strongly restrict them.
           Only the following authattrs are permitted and all others are
           rejected:

           (a) contentType.  This is checked to be an OID that matches the
                 content type in the SignedData object.

           (b) messageDigest.  This must match the crypto digest of the data.

           (c) signingTime.  If present, we check that this is a valid, 
parseable
                 UTCTime or GeneralTime and that the date it encodes fits within
                 the validity window of the matching X.509 cert.

           (d) S/MIME capabilities.  We don't check the contents.

           (e) Authenticode SP Opus Info.  We don't check the contents.

           (f) Authenticode Statement Type.  We don't check the contents.

           The message is rejected if (a) or (b) are missing.  If the message is
           an Authenticode type, the message is rejected if (e) is missing; if
           not Authenticode, the message is rejected if (d) - (f) are present.

           The S/MIME capabilities authattr (d) unfortunately has to be allowed
           to support kernels already signed by the pesign program.  This only
           affects kexec.  sign-file suppresses them (CMS_NOSMIMECAP).

           The message is also rejected if an authattr is given more than once 
or
           if it contains more than one element in its set of values.

       (3) Add a parameter to pkcs7_verify() to select one of the following
           restrictions and pass in the appropriate option from the callers:

           (*) VERIFYING_MODULE_SIGNATURE

         This requires that the SignedData content type be pkcs7-data and
         forbids authattrs.  sign-file sets CMS_NOATTR.  We could be more
         flexible and permit authattrs optionally, but only permit minimal
         content.

           (*) VERIFYING_FIRMWARE_SIGNATURE

         This requires that the SignedData content type be pkcs7-data and
         requires authattrs.  In future, this will require an attribute
         holding the target firmware name in addition to the minimal set.

           (*) VERIFYING_UNSPECIFIED_SIGNATURE

         This requires that the SignedData content type be pkcs7-data but
         allows either no authattrs or only permits the minimal set.

           (*) VERIFYING_KEXEC_PE_SIGNATURE

         This only supports the Authenticode SPC_INDIRECT_DATA content type
         and requires at least an SpcSpOpusInfo authattr in addition to the
         minimal set.  It also permits an SPC_STATEMENT_TYPE authattr (and
         an S/MIME capabilities authattr because the pesign program doesn't
         remove these).

           (*) VERIFYING_KEY_SIGNATURE
           (*) VERIFYING_KEY_SELF_SIGNATURE

         These are invalid in this context but are included for later use
         when limiting the use of X.509 certs.

       (4) The pkcs7_test key type is given a module parameter to select between
           the above options for testing purposes.  For example:

        echo 1 >/sys/module/pkcs7_test_key/parameters/usage
        keyctl padd pkcs7_test foo @s </tmp/stuff.pkcs7

           will attempt to check the signature on stuff.pkcs7 as if it contains 
a
           firmware blob (1 being VERIFYING_FIRMWARE_SIGNATURE).

      This is not required for the module signing key, although it doesn't do 
any
      harm â?? it just means that any additional certs in the PEM file are also
      trusted by the kernel.

      But it does allow us to use the extract-cert tool for processing the extra

      sign-file: Generate CMS message as signature instead of PKCS#7

      Make sign-file use the OpenSSL CMS routines to generate a message to be
      used as the signature blob instead of the PKCS#7 routines.  This allows us
      to change how the matching X.509 certificate is selected.  With PKCS#7 the
      only option is to match on the serial number and issuer fields of an X.509
      certificate; with CMS, we also have the option of matching by subjectKeyId
      extension.  The new behaviour is selected with the "-k" flag.

      Without the -k flag specified, the output is pretty much identical to the
      PKCS#7 output.

      Whilst we're at it, don't include the S/MIME capability list in the 
message
      as it's irrelevant to us.

      X.509: Change recorded SKID & AKID to not include Subject or Issuer

      The key identifiers fabricated from an X.509 certificate are currently:

       (A) Concatenation of serial number and issuer

       (B) Concatenation of subject and subjectKeyID (SKID)

      When verifying one X.509 certificate with another, the AKID in the target
      can be used to match the authoritative certificate.  The AKID can specify
      the match in one or both of two ways:

       (1) Compare authorityCertSerialNumber and authorityCertIssuer from the 
AKID
           to identifier (A) above.

       (2) Compare keyIdentifier from the AKID plus the issuer from the target
           certificate to identifier (B) above.

      When verifying a PKCS#7 message, the only available comparison is between
      the IssuerAndSerialNumber field and identifier (A) above.

      However, a subsequent patch adds CMS support.  Whilst CMS still supports a
      match on IssuerAndSerialNumber as for PKCS#7, it also supports an
      alternative - which is the SubjectKeyIdentifier field.  This is used to
      match to an X.509 certificate on the SKID alone.  No subject information 
is
      available to be used.

      To this end change the fabrication of (B) above to be from the X.509 SKID
      alone.  The AKID in keyIdentifier form then only matches on that and does
      not include the issuer.

      vgaarb: Stop complaining about absent devices

      Some setups do not register a default VGA device, in which case the VGA
      arbiter will still complain about the (non-existent) PCI device being a
      non-VGA device.

      Fix this by making the error message conditional on a default VGA device
      having been set up. Note that the easy route of erroring out early isn't
      going to work because otherwise priv->target won't be properly updated.

      KVM: arm/arm64: vgic: Prevent userspace injection of a mapped interrupt

      Virtual interrupts mapped to a HW interrupt should only be triggered
      from inside the kernel. Otherwise, you could end up confusing the
      kernel (and the GIC's) state machine.

      Rearrange the injection path so that kvm_vgic_inject_irq is
      used for non-mapped interrupts, and kvm_vgic_inject_mapped_irq is
      used for mapped interrupts. The latter should only be called from
      inside the kernel (timer, irqfd).

          #

          It can be combined with other fields, for instance, experiment with

          There are some oddities in some distros and with some specific DSOs, 
being
          investigated, so your mileage may vary.

      sched: Change the sched_class::set_cpus_allowed() calling context

      Change the calling context of sched_class::set_cpus_allowed() such
      that we can assume the task is inactive.

      This allows us to easily make changes that affect accounting done by
      enqueue/dequeue. This does in fact completely remove
      set_cpus_allowed_rt() and greatly reduces set_cpus_allowed_dl().

      Because sched_setscheduler() checks p->flags & PF_NO_SETAFFINITY
      without locks, a caller might observe an old value and race with the
      set_cpus_allowed_ptr() call from __kthread_bind() and effectively undo

        __kthread_bind()
          do_set_cpus_allowed()
                                                <SYSCALL>

                                                    if (p->flags & 
PF_NO_SETAFFINITIY)
                                                    set_cpus_allowed_ptr()
          p->flags |= PF_NO_SETAFFINITY

      Fix the bug by putting everything under the regular scheduler locks.

      This also closes a hole in the serialization of 
task_struct::{nr_,}cpus_allowed.

      sched: Ensure a task has a non-normalized vruntime when returning back to 
CFS

      Current code ensures that a task has a normalized vruntime when switching 
away
      from the fair class, but it does not ensure the task has a non-normalized
      vruntime when switching back to the fair class.

      This is an example breaking this consistency:

        1. a task is in fair class and !queued
        2. changes its class to RT class (still !queued)
        3. changes its class to fair class again (still !queued)

      sched/numa: Fix NUMA_DIRECT topology identification

      Systems which have all nodes at a distance of at most 1 hop should be
      identified as 'NUMA_DIRECT'.

      However, the scheduler incorrectly identifies it as 'NUMA_BACKPLANE'.
      This is because 'n' is assigned to sched_max_numa_distance but the
      code (mis)interprets it to mean 'number of hops'.

      Rik had actually used sched_domains_numa_levels for detecting a
      'NUMA_DIRECT' topology:

        http://marc.info/?l=linux-kernel&m=141279712429834&w=2

      But that was changed when he removed the hops table in the
      subsequent version:

      When we release a regulator we need to remove references to it from the
      rdev which means locking the rdev.  Currently we also free resources
      associated with the regulator inside the rdev lock but there is no need
      to do this, we can reduce the region the lock is held by restricting it
      to just actions that affect the rdev.

      locking/atomics: Add _{acquire|release|relaxed}() variants of some atomic 
operations

      Whilst porting the generic qrwlock code over to arm64, it became
      apparent that any portable locking code needs finer-grained control of
      the memory-ordering guarantees provided by our atomic routines.

      In particular: xchg, cmpxchg, {add,sub}_return are often used in
      situations where full barrier semantics (currently the only option
      available) are not required. For example, when a reader increments a
      reader count to obtain a lock, checking the old value to see if a writer
      was present, only acquire semantics are strictly needed.

      This patch introduces three new ordering semantics for these operations:

        - *_relaxed: No ordering guarantees. This is similar to what we have
                     already for the non-return atomics (e.g. atomic_add).

        - *_acquire: ACQUIRE semantics, similar to smp_load_acquire.

        - *_release: RELEASE semantics, similar to smp_store_release.

      In memory-ordering speak, this means that the acquire/release semantics
      are RCpc as opposed to RCsc. Consequently a RELEASE followed by an
      ACQUIRE does not imply a full barrier, as already documented in
      memory-barriers.txt.

      Currently, all the new macros are conditionally mapped to the full-mb
      variants, however if the *_relaxed version is provided by the
      architecture, then the acquire/release variants are constructed by
      supplementing the relaxed routine with an explicit barrier.

      locking, compiler.h: Cast away attributes in the WRITE_ONCE() magic

      The kernel build bot showed a new warning triggered by commit:

        76695af20c01 ("locking, arch: use WRITE_ONCE()/READ_ONCE() in 
smp_store_release()/smp_load_acquire()")

      because Sparse does not like WRITE_ONCE() accessing elements
      from the (sparse) RCU address space:

        fs/afs/inode.c:448:9: sparse: incorrect type in initializer (different 
address spaces)
        fs/afs/inode.c:448:9:    expected struct afs_permits *__val
        fs/afs/inode.c:448:9:    got void [noderef] <asn:4>*<noident>

      Solution is to force cast away the sparse attributes for the initializer
      of the union in WRITE_ONCE().

      (And as this now gets too long, also split the macro into multiple lines.)

      perf/ring-buffer: Clarify the use of page::private for high-order AUX 
allocations

      A question [1] was raised about the use of page::private in AUX buffer
      allocations, so let's add a clarification about its intended use.

      The private field and flag are used by perf's rb_alloc_aux() path to
      tell the pmu driver the size of each high-order allocation, so that the
      driver can program those appropriately into its hardware. This only
      matters for PMUs that don't support hardware scatter tables. Otherwise,
      every page in the buffer is just a page.

      This patch adds a comment about the private field to the AUX buffer
      allocation path.

      perf/x86: Fix MSR PMU driver

      Currently we only update the sysfs event files per available MSR, we
      didn't actually disallow creating unlisted events.

      Rework things such that the dectection, sysfs listing and event
      creation are better coordinated.

      Sadly it appears it's impossible to probe R/O MSRs under virt. This
      means we have to do the full model table to avoid listing all MSRs all
      the time.

      mfd: axp20x: Add a cell for the usb power_supply part of the axp20x PMICs

      Add a cell for the usb power_supply part of the axp20x PMICs.

      Note that this cell is only for the usb power_supply part and not the
      ac-power / battery-charger / rtc-backup-bat-charger bits.

      Depending on the board each of those must be enabled / disabled separately
      in devicetree as most boards do not use all 4. So in dt each one needs its
      own child-node of the axp20x node. Another reason for using separate child
      nodes for each is so that other devicetree nodes can have a power-supply
      property with a phandle referencing a node representing a single
      power-supply.

      The decision to use a separate devicetree node for each is reflected on
      the kernel side by each getting its own mfd-cell / platform_device and
      platform-driver.

      Note this commit also makes some whitespace changes to the intialization
      of existing cells in axp20x_cells, these are pure whitespace changes,
      functionally nothing changes.

      clk: track the orphan status of clocks and their children

      While children of orphan clocks are not carried in the orphan-list itself,
      they're nevertheless orphans in their own right as they also don't have an
      input-rate available. To ease tracking if a clock is an orphan or has an
      orphan in its parent path introduce an orphan field into struct clk and
      update it and the fields in child-clocks when a clock gets added or 
removed
      from the orphan-list.

      The code to fetch the SLB size from the device tree wants to first look

      We can simplify the code by looking for the properties and then if we
      find one of them we set mmu_slb_size.

      We also change the function name from check_cpu_slb_size() to
      init_mmu_slb_size() as the function doesn't check anything, it only
      initialises mmu_slb_size.

      cxl: sparse: Silence iomem warning in debugfs file creation

      An IO address, tagged with __iomem, is passed to debugfs_create_file
      as private data. This requires that it be cast to void *. The cast
      drops the __iomem annotation and so creates a sparse warning:

        drivers/misc/cxl/debugfs.c:51:57: warning: cast removes address space 
of expression

      The Exynos5420 based Peach Pit and Exynos5800 based Peach Pi Chromebooks
      use the Maxim max77802 Power Management IC (PMIC). This PMIC has besides
      other devices, a set of regulators that can be controller over I2C.

      Commit f3caa529c6f5 ("ARM: multi_v7_defconfig: Enable max77802 regulator,
      rtc and clock drivers") was supposed to enable the config option for the
      regulator driver as a module but the final version that landed did not
      include this. The commit was modified and the REGULATOR_MAX77802 removed
      since it was thought to be useless.

      Unfortunately that's not the case for the mentioned reason above so this
      patch enables the needed Kconfig option.

      tracing: Allow triggers to filter for CPU ids and process names

      By extending the filter rules by more generic fields
      we can write triggers filters like

        echo 'stacktrace if cpu == 1' > \
        /sys/kernel/debug/tracing/events/raw_syscalls/sys_enter/trigger

      or

        echo 'stacktrace if comm == sshd'  > \
        /sys/kernel/debug/tracing/events/raw_syscalls/sys_enter/trigger

      CPU and COMM are not part of struct trace_entry. We could add the two
      new fields to ftrace_common_field list and fix up all depending
      sides. But that looks pretty ugly. Another thing I would like to
      avoid that the 'format' file contents changes.

      All this can be avoided by introducing another list which contains
      non field members of struct trace_entry.

      PCI: dra7xx: Clear MSE bit during suspend so clocks will idle

      DRA7xx requires the MSE bit to be cleared to set the master in standby
      mode.  (In DRA7xx TRM_vE, section 24.9.4.5.2.2.1 PCIe Controller Master
      Standby Behavior advises to use the clearing of the local MSE bit to set
      the master in standby.  Without this some of the clocks do not idle).

      Clear the MSE bit on suspend and enable it on resume.  Clearing MSE bit is
      required to get clocks to be idled after suspend.

      PCI: Kill off set_irq_flags() usage

      set_irq_flags is ARM-specific with custom flags which have genirq
      equivalents.  Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags.  The translation of flags is as follows:

        IRQF_VALID -> !IRQ_NOREQUEST
        IRQF_PROBE -> !IRQ_NOPROBE
        IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in 
.map()
      functions, and we can simply remove the set_irq_flags calls.  Some users
      also modify IRQ_NOPROBE, and this has been maintained although it is not
      clear that is really needed.  There appears to be a great deal of blind
      copy and paste of this code.

      Vivien Didelot says:

      ====================
      net: dsa: mv88e6xxx: support switchdev FDB objects

      This patchset refactors the FDB management in the mv88e6xxx code and adds 
the
      glue in DSA to use the switchdev FDB objects.

      Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to 
br1):

          # bridge fdb add 3c:97:0e:11:30:6e dev swp2
          # bridge fdb add 3c:97:0e:11:40:78 dev swp3
          # bridge fdb add 3c:97:0e:11:50:86 dev swp4
          # bridge fdb del 3c:97:0e:11:40:78 dev swp3
          # bridge fdb
          01:00:5e:00:00:01 dev eth0 self permanent
          01:00:5e:00:00:01 dev eth1 self permanent
          00:50:d2:10:78:15 dev swp0 master br0 permanent
          3c:97:0e:11:30:6e dev swp2 self static
          00:50:d2:10:78:15 dev swp3 master br1 permanent
          3c:97:0e:11:50:86 dev swp4 self static
          # cat /sys/kernel/debug/dsa0/atu
          # DB   T/P  Vec State Addr
          # 001  Port 004   e   3c:97:0e:11:30:6e
          # 004  Port 010   e   3c:97:0e:11:50:86

      For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for 
non-bridged
      ports and bridge groups, and the remaining will be later used by VLANs.

      This change is necessary to welcome the support for hardware VLANs (which 
will
      follow soon).

      Changes in v3:

       - reorder commits to improve bisectability and minimize diffs

       - add an ndm_state member in switchdev_fdb_obj instead of an is_static 
boolean

       - drop the need to convert unsigned char *addr to u8 addr[ETH_ALEN]
         (it is casted to char pointer anyway)

      Changes in v2:

       - remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code

       - use ether_addr_copy instead of memcpy for MAC addresses

       - constify MAC address in port_fdb_{add,del}

       - split the mv88e6xxx code refactoring into several patches

      net: dsa: mv88e6xxx: extend fid mask

      The driver currently manages one FID per port (or bridge group), with a
      mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

      The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
      FID 0 means that multiple address databases are not being used).

      This patch changes the fid_mask for an fid_bitmap of 4096 bits.

      >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
      bridge groups (a bridge group gets the FID of its first member). The
      remaining bits will be reserved for VLAN entries.

      [media] stv0367: Refine i2c error trace to include i2c address

      When using stv0367 demodulator with STi STB platforms,
      we can have easily have four or more stv0367 demods running
      in the system at one time.

      As typically the b2120 reference design ships with a b2004a daughter
      board, which can accept two dvb NIM cards, and each b2100A NIM
      has 2x stv0367 demods and 2x NXPs tuner on it.

      In such circumstances it is useful to print the i2c address
      on error messages to know which one is failing due to I2C issues.

      f2fs: remove inmem radix tree

      Previously, we use radix tree to index all registered page entries for
      atomic file, but now we only use radix tree to see whether current page
      is indexed or not, since the other user of radix tree is gone in commit
      042b7816aaeb ("f2fs: remove unnecessary call to invalidate inmemory 
pages").

      So in this patch, we try to use one more efficient way:
      Introducing a macro ATOMIC_WRITTEN_PAGE, and setting it as page private
      value to indicate page indexing status. By using this way, we can save
      memory and lookup time.

      f2fs: report EINVAL for unalignment direct IO

      We run ltp testcase with f2fs and obtain a TFAIL in diotest4, the result 
in
      detail is as fallow:

      dio04

      <<<test_start>>>
      tag=dio04 stime=1432278894
      cmdline="diotest4"
      contacts=""

      <<<test_output>>>
      diotest4    1  TPASS  :  Negative Offset
      diotest4    2  TPASS  :  removed
      diotest4    3  TFAIL  :  diotest4.c:129: write allows odd count.returns 
1: Success
      diotest4    4  TFAIL  :  diotest4.c:183: Odd count of read and write
      diotest4    5  TPASS  :  Read beyond the file size
      ......

      the result of ext4 with same environment:

      dio04

      <<<test_start>>>
      tag=dio04 stime=1432259643
      cmdline="diotest4"
      contacts=""
      analysis=exit
      <<<test_output>>>
      diotest4    1  TPASS  :  Negative Offset
      diotest4    2  TPASS  :  removed
      diotest4    3  TPASS  :  Odd count of read and write
      diotest4    4  TPASS  :  Read beyond the file size
      ......

      The reason is that when triggering DIO in f2fs, we will return zero value
      in ->direct_IO if writer's buffer offset, file offset and transfer size is
      not alignment to block size of filesystem, resulting in falling back into
      buffered write instead of returning -EINVAL.

      This patch fixes that problem by returning correct error number for above
      case, and removing the judgement condition in check_direct_IO to make sure
      the verification will be enabled for direct reader too.

      Besides, Jaegeuk Kim pointed out that there is expectional cases we should
      always make direct-io falling back into buffered write, such as dio in
      encrypted file.

      cgroup: make cftype->private a unsigned long

      It's pretty unusual to have an int as a private data field and it
      makes it impossible to carray a pointer value through it.  Let's make
      it an unsigned long.  AFAICS, this shouldn't break anything.

      spi: orion: On a38x, implement "50MHZ SPI AC timing" Erratum No. 
FE-9144572

      Description:
      On Armada 38x, the device SPI interface supports frequencies of up to
      50 MHz. However, due to this erratum, when the device core clock is
      250 MHz and the SPI interfaces is configured for 50MHz SPI clock and
      CPOL=CPHA=1, there might occur data corruption on reads from the SPI
      device.

      Workaround:
      Work in one of the following configurations:
      1. Set CPOL=CPHA=0 in "SPI Interface Configuration Register".
      2. Set TMISO_SAMPLE value to 0x2 in "SPI Timing Parameters 1 Register"
      before setting the interface.

      [gregory.clement@xxxxxxxxxxxxxxxxxx}: port to v4.2-rc, use
      is_errata_50mhz_ac instead of using a new ARMADA_380_SPI spi type.

      batman-adv: Avoid u32 overflow during gateway select

      The gateway selection based on fast connections is using a single value
      calculated from the average tq (0-255) and the download bandwidth (in
      100Kibit). The formula for the first step (tq ** 2 * 10000 * bandwidth)
      tends to overflow a u32 with low bandwidth settings like 50 [100KiBit]
      and a tq value of over 92.

      Changing this to a 64 bit unsigned integer allows to support a
      bandwidth_down with up to ~2.8e10 [100KiBit] and a perfect tq of 255. This
      is ~6.6 times higher than the maximum possible value of the gateway
      announcement TVLV.

      This problem only affects the non-default gw_sel_class 1.

      batman-adv: Replace gw_reselect divisor with simple shift

      The gw_factor is divided by BATADV_TQ_LOCAL_WINDOW_SIZE ** 2 * 64. But the
      rest of the calculation has nothing to do with the tq window size and
      therefore the calculation is just (tmp_gw_factor / (64 ** 3)).

      Replace it with a simple shift to avoid a costly 64-bit divide when the
      max_gw_factor is changed from u32 to u64. This type change is necessary
      to avoid an overflow bug.

with pr_warn()

      On built-in kernels this warning will always splat as this is part
      of the module init. Fix that by shifting the PAT requirement check
      out under the code that does the "quasi-probe" for the device. This
      device driver relies on an existing driver to find its own devices,
      it looks for that device driver and its own found devices, then
      uses driver_for_each_device() to try to see if it can probe each of
      those devices as a frambuffer device with ivtvfb_init_card(). We
      tuck the PAT requiremenet check then on the ivtvfb_init_card()
      call making the check at least require an ivtv device present
      before complaining.

      mfd: wm8994: Fix NULL pointer exception on missing pdata

      If we use the dev_get_platdata, pdata can be NULL in DT environments.
      Actually, NULL pointer exception is occurs with error messages like this:

      [    1.226583] Unable to handle kernel NULL pointer dereference at 
virtual address 00000044
      [    1.467910] [<c02f1e38>] (wm8994_irq_init) from [<c02f1bd4>]

(i2c_device_probe+0x11c/0x17c)

      In wm8994-core, we already checked whether platform data is NULL and set 
the
      wm8994->pdata to platform data if platform data is not NULL.
      So, we can use wm8994->pdata instead of platform data.

      mfd: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So the driver needs to export the I2C table and this
      be built into the module or udev won't have the necessary information
      to auto load the correct module when the device is added.

      mfd: max899x: Avoid redundant irq_data lookup

      It's pretty silly to do

           irq_data *d = irq_get_irq_data(irq_data->irq);

      because that results in d = irq_data, but goes through a lookup of the
      irq_data. Use irq_data directly.

      mfd: Kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      mfd: arizona: Fixup register table definitions

      The regmap register definitions have been a source of many small fixes
      as issues are discovered.  As such I made a small automated tool to
      check these definitions. This patch fixes the issues (mostly harmless)
      located by that tool, the issues fall into three catagories:

      1) Volatile registers that have a default in the defaults table (default
      has been removed from the table since it is redundant)
      2) Registers that are marked as volatile but unreadable (register has
      been removed from the volatile list since it is obviously not being
      used)
      3) Registers that arn't readable but have an entry in the defaults
      table (again removed since it is redundant)
      4) Readable non-volatile registers that are missing a default, these are
      dangerous as they won't get synced during a cache sync. Fortunately,
      most of them seem to be registers that shouldn't be there (for example
      wm5102 had readable registers for DRC2 and ISRC3 which is doesn't have)

      Hopefully another tool will be produced to check the actual default
      values themselves but that is outside the scope of this patch.

      mfd: Remove MFD_CROS_EC_SPI depends on OF

      The ChromeOS EC SPI transport driver has a dependency on OF because it
      uses some OF helpers from the <linux/of.h> header. But there isn't a
      need for an explicit dependency since the header has stub functions if
      CONFIG_OF is not defined.

      Also, MFD_CROS_EC_SPI already depends on MFD_CROS_EC which in turn has
      a dependency on OF so in practice can't be selected without CONFIG_OF.

      mfd: arizona: Fix race between runtime suspend and IRQs

      The function arizona_irq_thread (the threaded handler for the arizona
      IRQs) calls pm_runtime_get_sync at the start to ensure that the chip is
      active as we handle the IRQ. If the chip is part way through a runtime
      suspend when an IRQ arrives the PM core will wait for the suspend to
      complete, before resuming. However, since commit 4f0216409f7c
      ("mfd: arizona: Add better support for system suspend") the runtime
      suspend function may call disable_irq, if the chip is going to fully
      power off, which will try to wait for any outstanding IRQs to complete.
      This results in deadlock as the IRQ thread is waiting for the PM
      operation to complete and the PM thread is waiting for the IRQ to
      complete.

      To avoid this situation we use disable_irq_nosync, which allows the
      suspending thread to finish the suspend without waiting for the IRQ to
      complete. This is safe because if an IRQ is being processed it can only
      be blocked at the pm_runtime_get_sync at the start of the handler
      otherwise it wouldn't be possible to suspend.

      watchdog: iTCO_wdt: Add support for TCO on Intel Sunrisepoint

      The revision of the watchdog hardware in Sunrisepoint necessitates a new

      layouts have changed.

      Also update the Kconfig entry to select both the LPC and SMBus drivers
      since the TCO device is on the SMBus in Sunrisepoint.

      Starting from Intel Sunrisepoint (Skylake PCH) the iTCO watchdog resources
      have been moved to reside under the i801 SMBus host controller whereas
      previously they were under the LPC device.

      In order to support the iTCO watchdog on newer PCHs we need to create the

using
      platform data.

      mfd: watchdog: iTCO_wdt: Expose watchdog properties using platform data

      Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across
      the SMBus, unlike previous generations of PCH/ICH where it was on the
      LPC bus. Because it's on the SMBus, it doesn't make sense to pass around
      a 'struct lpc_ich_info', and leaking the type of bus into the iTCO
      watchdog driver is kind of backwards anyway.

      This change introduces a new 'struct itco_wdt_platform_data' for use
      inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint
      code, which neatly avoids having to include lpc_ich headers in the i801
      i2c driver.

      This change is overdue because lpc_ich_info has already found its way
      into other TCO watchdog users, notably the intel_pmc_ipc driver where
      the watchdog actually isn't on the LPC bus as far as I can see.

      A simple translation layer is provided for converting from the existing
      'struct lpc_ich_info' inside the lpc_ich mfd driver.

      KVM: x86/vPMU: Fix unnecessary signed extension for AMD PERFCTRn

      According to AMD programmer's manual, AMD PERFCTRn is 64-bit MSR which,
      unlike Intel perf counters, doesn't require signed extension. This
      patch removes the unnecessary conversion in SVM vPMU code when PERFCTRn
      is being updated.

      ARM: brcmstb: select ARCH_DMA_ADDR_T_64BIT for LPAE

      Broadcom STB (BRCMSTB) has some 64-bit capable DMA and therefore needs
      dma_addr_t to be a 64-bit size.  One user is the Broadcom SATA3 AHCI
      controller driver.

      [media] media: adv7604: reduce support to first (digital) input

      Using adv7611_read_cable_det() for ADV7612 means that full
      support for '.max_port = ADV7604_PAD_HDMI_PORT_B,' isn't available
      due to the need for multiple port reads to determine cable detection,
      and an agreed mechanism for communicating the separate statuses.

      This patch replaces adv7611_read_cable_det() with a functionally
      identical copy, commented appropriately.

      Earlier submissions [leading to commit 8331d30b] also set .cp_csc,
      which is used in a cp_read() call within adv76xx_log_status().

      xfrm6: Fix IPv6 ECN decapsulation

      Using ipv6_get_dsfield on the outer IP header implies that inner and
      outer header are of the the same address family. For interfamily
      tunnels, particularly 646, the code reading the DSCP field obtains the
      wrong values (IHL and the upper four bits of the DSCP field).
      This can cause the code to detect a congestion encoutered state in the
      outer header and enable the corresponding bits in the inner header, too.

      Since the DSCP field is stored in the xfrm mode common buffer
      independently from the IP version of the outer header, it's safe (and
      correct) to take this value from there.

      netfilter: nf_conntrack: push zone object into functions

      This patch replaces the zone id which is pushed down into functions
      with the actual zone object. It's a bigger one-time change, but
      needed for later on extending zones with a direction parameter, and
      thus decoupling this additional information from all call-sites.

      No functional changes in this patch.

      The default zone becomes a global const object, namely nf_ct_zone_dflt
      and will be returned directly in various cases, one being, when there's
      f.e. no zoning support.

          drm/atomic: Only destroy connector states with connection mutex held

      I tried to fix races of atomic commits against connector
      hot-unplugging. The idea is to ensure lifetimes by holding the
      connection_mutex long enough. That works for synchronous commits, but
      not for async ones.

      For async atomic commit we really need to fix up connector lifetimes
      for real. But that's a much bigger task, so just add more duct-tape:
      For cleaning up connector states we currently don't need the connector
      itself. So NULL it out and remove the locking check. Of course that
      check was to protect the entire sequence, but the modeset itself
      should be save since currently DP MST hot-removal does a dpms-off. And
      that should synchronize with any outstanding async atomic commit.

      Or at least that's my hope, this is all a giant mess.

      drm/rockchip: Don't grab dev->struct_mutex for in mmap offset ioctl

      Since David Herrmann's mmap vma manager rework we don't need to grab
      dev->struct_mutex any more to prevent races when looking up the mmap
      offset. Drop it and instead don't forget to use the unref_unlocked
      variant (since the drm core still cares).

      Aside: I stumbled over the mmap handler which directly does a
      dma_mmap_attrs. But totally fails to grab a reference on the
      underlying object and hence looks like it happily just leaks the ptes
      since there's no guarantee the mmap isn't still around when
      gem_free_object is called. Which the kerneldoc of dma_mmap_attrs

      [media] bt819/saa7110/vpx3220: remove legacy control ops

      The zoran driver has now been converted to the control framework
      which means that these three subdevice drivers no longer need to
      support the legacy core control ops since the last bridge driver
      that needed that has now been converted.

      [media] usbvision: remove power_on_at_open and timed power off

      This causes lots of problems and is *very* slow as well.

      One of the main problems is that this prohibits the use of the control
      framework since subdevs will be unloaded on power off which is not allowed
      as long as they are used by a usb device.

      Apparently the reason for doing this is to turn off a noisy tuner. My 
hardware
      has no problem with that, and I wonder whether the hardware with that 
noisy
      tuner wasn't just functioning improperly as I have never heard of noisy 
tuners.

      Contact me if you have one of those devices and I can take a look whether 
the
      tuner can't be powered off if necessary by letting the tuner subdevice go
      into standby mode. Unloading the tuner module is just evil and is not the
      right approach.

      [media] V4L2: platform: Add Renesas R-Car JPEG codec driver

      Here's the driver for the Renesas R-Car JPEG processing unit.

      The driver is implemented within the V4L2 framework as a memory-to-memory
      device.  It presents two video nodes to userspace, one for the encoding 
part,
      and one for the decoding part.

      It was found that the only working mode for encoding is no markers 
output, so we
      generate markers with software. In the current version of driver we also 
use
      software JPEG header parsing because with hardware parsing performance is 
lower
      than desired.

      >From a userspace point of view the process is typical (S_FMT, REQBUF,
      optionally QUERYBUF, QBUF, STREAMON, DQBUF) for both the source and 
destination
      queues. STREAMON can return -EINVAL in case of mismatch of output and 
capture
      queues format. Also during decoding driver can return buffers if queued
      buffer with JPEG image contains image with inappropriate subsampling (e.g.
      4:2:0 in JPEG and 4:2:2 in capture).  If JPEG image and queue format 
dimensions
      differ driver will return buffer on QBUF with VB2_BUF_STATE_ERROR flag.

      During encoding the available formats are: V4L2_PIX_FMT_NV12M,
      V4L2_PIX_FMT_NV12, V4L2_PIX_FMT_NV16, V4L2_PIX_FMT_NV16M for source and
      V4L2_PIX_FMT_JPEG for destination.

      During decoding the available formats are: V4L2_PIX_FMT_JPEG for source 
and
      V4L2_PIX_FMT_NV12M, V4L2_PIX_FMT_NV16M, V4L2_PIX_FMT_NV12, 
V4L2_PIX_FMT_NV16
      for destination.

      Performance of current version:
      1280x800 NV12 image encoding/decoding
        decoding ~122 FPS
        encoding ~191 FPS

      [media] s5p-jpeg: Eliminate double kfree()

      video_unregister_device() calls device_unregister(), which calls
      put_device(), which calls kobject_put(), and if this is the last reference
      then kobject_release() is called, which calls kobject_cleanup(), which
      calls ktype's release method which happens to be device_release() in this
      case, which calls dev->release(), which happens to be
      v4l2_device_release() in this case, which calls vdev->release(), which
      happens to be video_device_release(). But video_device_release() is
      called explicitly both in error recovery path of s5p_jpeg_probe() and
      in s5p_jpeg_remove(). The pointers in question are not nullified between
      the two calls, so this is harmful.

      This patch fixes the driver so that video_device_release() is not called
      twice for the same object.

      ideapad-laptop: add alternative representation for Yoga 2 to DMI table

      There is at least one (mine) Yoga 2 Pro in existence that has incorrect
      product version stored in DMI (reading as "INVALID"), causing it to not be
      recognized as Yoga 2 by ideapad-laptop module, which in turn causes
      non-existent hardware rfkills to be always reported as blocked.

      This change adds a second check by board name, which is "Yoga2".
      Looks like it also happens to be "INVALID" on some other Yoga 2 machines
      where product version is correct instead, so the original check is left
      intact to catch both cases.

      asus-laptop: Add key found on Asus F3M

      Asus F3M has two keys labeled with an icon of a touchpad. The first,
      reported as 0x6B is next to the power key and the second, reported as
      0x6A, is F9 combined with Fn button. When I was pressing the latter, I was
      getting "Unknown key 6a pressed" message before applying this patch.

      Asus F3M does not support WMI so the commit does not update key mappings
      in the asus-nb-wmi.c file.

      I have not tested this mapping on any other Asus laptop.

      cleanup IORESOURCE_CACHEABLE vs ioremap()

      Quoting Arnd:
          I was thinking the opposite approach and basically removing all uses
          of IORESOURCE_CACHEABLE from the kernel. There are only a handful of
          them.and we can probably replace them all with hardcoded
          ioremap_cached() calls in the cases they are actually useful.

      All existing usages of IORESOURCE_CACHEABLE call ioremap() instead of
      ioremap_nocache() if the resource is cacheable, however ioremap() is
      uncached by default. Clearly none of the existing usages care about the
      cacheability. Particularly devm_ioremap_resource() never worked as
      advertised since it always fell back to plain ioremap().

      Clean this up as the new direction we want is to convert
      ioremap_<type>() usages to memremap(..., flags).

      mm: enhance region_is_ram() to region_intersects()

      region_is_ram() is used to prevent the establishment of aliased mappings
      to physical "System RAM" with incompatible cache settings.  However, it
      uses "-1" to indicate both "unknown" memory ranges (ranges not described
      by platform firmware) and "mixed" ranges (where the parameters describe
      a range that partially overlaps "System RAM").

      Fix this up by explicitly tracking the "unknown" vs "mixed" resource
      cases and returning REGION_INTERSECTS, REGION_MIXED, or REGION_DISJOINT.
      This re-write also adds support for detecting when the requested region
      completely eclipses all of a resource.  Note, the implementation treats
      overlaps between "unknown" and the requested memory type as
      REGION_INTERSECTS.

      Finally, other memory types can be passed in by name, for now the only
      usage "System RAM".

      HID: wacom: Simplify 'wacom_pl_irq'

      Unlike other IRQ functions, 'wacom_pl_irq' uses the second element of
      the 'tool' array to store information about its single pen. This makes
      the function more difficult to understand (since it doesn't follow the
      general pattern of other IRQ functions) and prevents the possibility of
      refactoring how pen state is stored.

      This patch rewrites 'wacom_pl_irq' to follow the usual IRQ conventions,
      including storing tool type in 'tool[0]' and implicitly tracking prox
      with the 'id[0]' variable.

      Kernel threads excluded from smack checks

      Adds an ignore case for kernel tasks,
      so that they can access all resources.

      Since kernel worker threads are spawned with
      floor label, they are severely restricted by
      Smack policy. It is not an issue without onlycap,
      as these processes also run with root,
      so CAP_MAC_OVERRIDE kicks in. But with onlycap
      turned on, there is no way to change the label
      for these processes.

      dsa: Support multiple MDIO busses

      When using a cluster of switches, some topologies will have an MDIO
      bus per switch, not one for the whole cluster. Allow this to be
      represented in the device tree, by adding an optional mii-bus property
      at the switch level. The old platform_device method of instantiation
      supports this already, so only the device tree binding needs extending
      with an additional optional phandle.

      net: add explicit logging and stat for neighbour table overflow

      Add an explicit neighbour table overflow message (ratelimited) and
      statistic to make diagnosing neighbour table overflows tractable in
      the wild.

      Diagnosing a neighbour table overflow can be quite difficult in the wild
      because there is no explicit dmesg logged.  Callers to neighbour code
      seem to use net_dbg_ratelimit when the neighbour call fails which means
      the "base message" is not emitted and the callback suppressed messages
      from the ratelimiting can end-up juxtaposed with unrelated messages.
      Further, a forced garbage collection will increment a stat on each call
      whether it was successful in freeing-up a table entry or not, so that
      statistic is only a hint.  So, add a net_info_ratelimited message and
      explicit statistic to the neighbour code.

        o Print buffer address which is holding a firmware dump.

                                                           bdp = 
fec_enet_get_nextdesc(txq->dirty_tx, fep, queue_id);
                                                           This bdp is the bdp 
reserved for the first segment. Given
                                                           that this bdp 
BD_ENET_TX_READY bit is not set and txq->cur_tx
                                                           is already pointed 
to a bdp beyond this one. We think this is a
                                                           completed bdp and 
try to reclaim it.
          update the bdp for the first segment
          update txq->cur_tx

      So we shouldn't update the txq->cur_tx until all the update to the
      bdps used for fragments are performed. Also add the corresponding
      memory barrier to guarantee that the update to the bdps, dirty_tx and
      cur_tx performed in the proper order.

      Now perf can set per-event value of time and (sampling) period.  But I
      guess most users like me just want to set frequency rather than period.
      So add the 'freq' term in the event parser.

      perf report: Add support for srcfile sort key

      In some cases it's useful to characterize samples by file. This is
      useful to get a higher level categorization, for example to map cost to
      subsystems.

      Add a srcfile sort key to perf report. It builds on top of the existing
      srcline support.

      Commiter notes:

      E.g.:

        # perf record -F 10000 usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.016 MB perf.data (13 samples) ]
        [root@zoo ~]# perf report -s srcfile --stdio
        # Total Lost Samples: 0
        #
        # Samples: 13  of event 'cycles'
        # Event count (approx.): 869878
        #
        # Overhead  Source File
        # ........  ...........

             4.04%  signal.c
             0.11%  msr.h

        #

somehow
      get resolved to:

      perf hists: Update the column width for the "srcline" sort key

      When we introduce a new sort key, we need to update the
      hists__calc_col_len() function accordingly, otherwise the width
      will be limited to strlen(header).

      We can't update it when obtaining a line value for a column (for
      instance, in sort__srcline_cmp()), because we reset it all when doing a
      resort (see hists__output_recalc_col_len()), so we need to, from what is
      in the hist_entry fields, set each of the column widths.

      svcrdma: Change maximum server payload back to RPCSVC_MAXPAYLOAD

      Both commit 0380a3f375 ("svcrdma: Add a separate "max data segs"
      macro for svcrdma") and commit 7e5be28827bf ("svcrdma: advertise
      the correct max payload") are incorrect. This commit reverts both
      changes, restoring the server's maximum payload size to 1MB.

      Commit 7e5be28827bf based the server's maximum payload on the
      _client's_ RPCRDMA_MAX_DATA_SEGS value. That was wrong.

      Commit 0380a3f375 tried to fix this so that the client maximum
      payload size could be raised without affecting the server, but
      managed to confuse matters more on the server side.

      More importantly, limiting the advertised maximum payload size was
      meant to be a workaround, not the actual fix. We need to revisit

        https://bugzilla.linux-nfs.org/show_bug.cgi?id=270

      A Linux client on a platform with 64KB pages can overrun and crash
      an x86_64 NFS/RDMA server when the r/wsize is 1MB. An x86/64 Linux
      client seems to work fine using 1MB reads and writes when the Linux
      server's maximum payload size is restored to 1MB.

      Bluetooth: Enable new connection establishment procedure.

      Currently, when trying to connect to already paired device that just
      rotated its RPA MAC address, old address would be used and connection
      would fail. In order to fix that, kernel must scan and receive
      advertisement with fresh RPA before connecting.

      This patch enables new connection establishment procedure. Instead of just
      sending HCI_OP_LE_CREATE_CONN to controller, "connect" will add device to
      kernel whitelist and start scan. If advertisement is received, it'll be
      compared against whitelist and then trigger connection if it matches.
      That fixes mentioned reconnect issue for  already paired devices. It also
      make whole connection procedure more robust. We can try to connect to
      multiple devices at same time now, even though controller allow only one.

      This patch makes sure that when new procedure is in use, and we're stuck
      in scan phase because no advertisement was received and timeout happened,
      or app decided to close socket, scan whitelist gets properly cleaned up.

      Bluetooth: add hci_connect_le_scan

      Currently, when trying to connect to already paired device that just
      rotated its RPA MAC address, old address would be used and connection
      would fail. In order to fix that, kernel must scan and receive
      advertisement with fresh RPA before connecting.

      This patch adds hci_connect_le_scan with dependencies, new method that
      will be used to connect to remote LE devices. Instead of just sending
      connect request, it adds a device to whitelist. Later patches will make
      use of this whitelist to send conenct request when advertisement is
      received, and properly handle timeouts.

      Bluetooth: preparation for new connect procedure

      Currently, when trying to connect to already paired device that just
      rotated its RPA MAC address, old address would be used and connection
      would fail. In order to fix that, kernel must scan and receive
      advertisement with fresh RPA before connecting.

      This patch adds some fields to hci_conn_params, in preparation to new
      connect procedure.

      explicit_connect will be used to override any current auto_connect action,
      and connect to device when ad is received.

      HCI_AUTO_CONN_EXPLICIT was added to auto_connect enum. When this value
      will be used, explicit connect is the only action, and params can be
      removed after successful connection.

      HCI_CONN_SCANNING is added to hci_conn flags. When it's set, connect is
      scan phase. It gets cleared when advertisement is received, and
      HCI_OP_LE_CREATE_CONN is sent.

      PCI: pciehp: Handle invalid data when reading from non-existent devices

      It's platform-dependent, but an MMIO read to a non-existent PCI device
      generally returns data with all bits set.  This happens when the host
      bridge or Root Complex times out waiting for a response from the device 
and
      fabricates return data to complete the CPU's read.

      One example, reported in the bugzilla below, involved this hierarchy:

        pci 0000:00:1c.0: PCI bridge to [bus 02-3a] Root Port
        pci 0000:02:00.0: PCI bridge to [bus 03-0a] Upstream Port
        pci 0000:03:03.0: PCI bridge to [bus 05-07] Downstream Port
        pci 0000:05:00.0: PCI bridge to [bus 06-07] Thunderbolt Upstream Port
        pci 0000:06:00.0: PCI bridge to [bus 07]    Thunderbolt Downstream Port
        pci 0000:07:00.0: BCM57762 NIC

      Unplugging the Thunderbolt switch and the NIC below it resulted in this:

        pciehp 0000:03:03.0: Surprise Removal
        tg3 0000:07:00.0: tg3_abort_hw timed out, TX_MODE_ENABLE will not clear 
MAC_TX_MODE=ffffffff
        pciehp 0000:06:00.0: unloading service driver pciehp
        pciehp 0000:06:00.0: pcie_isr: intr_loc 11f
        pciehp 0000:06:00.0: Switch interrupt received
        pciehp 0000:06:00.0: Latch open on Slot
        pciehp 0000:06:00.0: Attention button interrupt received
        pciehp 0000:06:00.0: Button pressed on Slot
        pciehp 0000:06:00.0: Presence/Notify input change
        pciehp 0000:06:00.0: Card present on Slot
        pciehp 0000:06:00.0: Power fault interrupt received
        pciehp 0000:06:00.0: Data Link Layer State change
        pciehp 0000:06:00.0: Link Up event

      The pciehp driver correctly noticed that the Thunderbolt switch (05:00.0
      and 06:00.0) and NIC (07:00.0) had been removed, and it called their 
driver
      remove methods.

      Since the NIC was already gone, tg3 received 0xffffffff when it tried to
      read from the device.  The resulting timeout is a tg3 issue and not of
      interest here.

      Similarly, since the 06:00.0 Thunderbolt switch was already gone,
      pcie_isr() received 0xffff when it tried to read PCI_EXP_SLTSTA, and 
pciehp
      thought that was valid status showing that many events had happened: the
      latch had been opened, the attention button had been pressed, a card was
      now present, and the link was now up.  These are all wrong, of course, but
      pciehp went on to try to power up and enumerate devices below the
      non-existent bridge:

        pciehp 0000:06:00.0: PCI slot - powering on due to button press
        pciehp 0000:06:00.0: Surprise Insertion
        pci 0000:07:00.0 id reading try 50 times with interval 20 ms to get 
ffffffff

      bcma: fix access to host_pdev for PCIe devices

      bus->host_pdev is part of a union so bus->host_pdev != NULL is probably
      also true for PCIe devices, because there it accesses bus->host_pci. If
      we access the dev member at the offset defined in struct
      platform_device in struct pci_dev instead we probably get something
      else.

      This patch adds a new function which returns the host dev struct and
      NULL if we do not have a host dev. When this gets registered on MIPS
      brcm47xx we do not have a host dev in some situations.
      This function could also be used in other places.

      This problem was introduced in this commit:

      wlcore: add p2p device support

      When starting a p2p mgmt interface, enable its device role. This
      allows us to keep the sta role disabled and scan on the dev role.

      In general, p2p management interfaces cannot send vif-specific commands
      to FW, as the vif role id is invalid. Only off-channel data and scans
      happen on this vif, so most ops are not relevant.

      If the vif is a p2p mgmt vif, block some mac80211 ops.

      Configure rate policies for p2p mgmt interface, as
      otherwise p2p packets come out with arbitrary rates.

      Since wpa_supplicant currently doesn't support standalone
      p2p device mode (without another attached managed interface),
      add p2p device to the allowed interface combinations without
      decreasing the allowed station count.

      Moreover, increase the station count in some cases, as AP
      mode usually starts as station interface, and the AP interface
      is now different from the p2p management one).

      mac802154: change frame_retries behaviour

      This patch changes the default minimum value of frame_retries to 0 and
      changes the frame_retries default value to 3 which is also 802.15.4
      default.

      We don't use the frame_retries "-1" value as indicator for no-aret mode
      anymore, instead we checking on the ack request bit inside the 802.15.4
      frame control field. This allows a acknowledge handling per frame. This
      checking is done by transceiver or inside xmit callback of driver layer.

      If a transceiver doesn't support ARET handling the transmit
      functionality ignores ack frames then, which isn't well but should not
      effect anything of current functionality.

      This patch removes several checks if a value is really changed. This
      makes only sense if we have another layer call e.g. calling the

      For MAC settings which need to be set by phy registers (if the phy
      supports that handling) this is set by doing an interface up currently
      and are not direct driver_ops calls, so we remove the checks from these

      mac802154: fix wpan mac setting while lowpan is there

      If we currently change the mac address inside the wpan interface while
      we have a lowpan interface on top of the wpan interface, the mac address
      setting doesn't reach the lowpan interface. The effect would be that the
      IPv6 lowpan interface has the old SLAAC address and isn't working
      anymore because the lowpan interface use in internal mechanism sometimes
      dev->addr which is the old mac address of the wpan interface.

      This patch checks if a wpan interface belongs to lowpan interface, if
      yes then we need to check if the lowpan interface is down and change the
      mac address also at the lowpan interface. When the lowpan interface will

      ieee802154: 6lowpan: remove multiple lowpan per wpan support

      We currently supports multiple lowpan interfaces per wpan interface. I
      never saw any use case into such functionality. We drop this feature now
      because it's much easier do deal with address changes inside the under
      laying wpan interface.

      This patch removes the multiple lowpan interface and adds a lowpan_dev
      netdev pointer into the wpan_dev, if this pointer isn't null the wpan
      interface belongs to the assigned lowpan interface.

      6lowpan: Fix extraction of flow label field

      The lowpan_fetch_skb function is used to fetch the first byte,
      which also increments the data pointer in skb structure,
      making subsequent array lookup of byte 0 actually being byte 1.

      To decompress the first byte of the Flow Label when the TF flag is
      set to 0x01, the second half of the first byte is needed.

      The patch fixes the extraction of the Flow Label field.

      crypto: talitos - Prevent panic in probe error path

      The probe error path for this driver, for all intents and purposes,
      is the talitos_remove() function due to the common "goto err_out".

      Without this patch applied, talitos_remove() will panic under these
      two conditions:

      1. If the RNG device hasn't been registered via
         talitos_register_rng() prior to entry into talitos_remove(),
         then the attempt to unregister the RNG "device" will cause a panic.

      2. If the priv->chan array has not been allocated prior to entry
         into talitos_remove(), then the per-channel FIFO cleanup will panic
         because of the dereference of that NULL "array".

      Both of the above scenarios occur if talitos_probe_irq() fails.

      This patch resolves issue #1 by introducing a boolean to mask the
      hwrng_unregister() call in talitos_unregister_rng() if RNG device
      registration was unsuccessful.

      It resolves issue #2 by checking that priv->chan is not NULL in the
      per-channel FIFO cleanup for loop.

      enables the required clocks when the CAAM module is initialized and
      disables the required clocks when the CAAM module is shut down.

      perf tools: Unset perf_event_attr::freq when period term is set

      We need to unset 'perf_event_attr::freq' bit (default 1) when
      'period' term is specified within event definition like:

        -e 'cpu/cpu-cycles,call-graph=fp,time,period=100000'

      otherwise it will handle the period value as frequency
      (and fail if it crossed the maximum allowed frequency value).

      perf tools: Support full source file paths for srcline

      For perf report/script srcline currently only the base file name of the
      source file is printed. This is a good default because it usually fits
      on the screen.

      But in some cases we want to know the full file name, for example to
      aggregate hits per file.

      In the later case we need more than the base file name to resolve file
      naming collisions: for example the kernel source has ~70 files named
      "core.c"

      It's also useful as input to post processing tools which want to point
      to the right file.

      Add a flag to allow full file name output.

      Add an option to perf report/script to enable this option.

      ALSA: hda - Fix pin config and mapping on Alienware 15

      Alienware 15 has CA0132 codec for its onboard sound, but the pin
      config and mapping seem quite different from other Creative boards.
      This patch corrects them, at least, for providing the right headphone
      and mic jack notification, as well as removing the non-existing SPDIF
      pins.

      Even with this fix, not all stuff works perfectly yet, mainly because
      of the badly written ca0132 driver code -- it has too many implicit
      assumptions of pin configs and maps.  Nevertheless, this is a small
      good step forward.

      ALSA: echoaudio: Use standard C definitions of true and false

      The echoaudio locally defines TRUE and FALSE.  Not only is this
      redundant given that C now has a boolean type it results in lots of
      warnings as other headers also define these macros, causing duplicate
      definitions.  Fix this by removing the local defines and converting all
      local users to use the standard C true and false instead, simply
      removing the macros is less safe due to implicit inclusion of the other
      definitons.

      As an extension of aef3156d7, there is no sense in repeatedly calling the
      'wacom_set_report' and 'wacom_get_report' functions if they return an
      error. Getting an error from them implies that the device is out to lunch:
      either a hard error code was returned or repeated attempts at recovering
      from a "soft" error all failed. In either case, doing even more retries is
      not likely to resolve whatever is wrong.

      ASoC: max98090: Fix sequencing when starting additional routes

      Enforce correct device sequencing when configuring a new
      audio route when there is an existing active audio route(s).

      This patch fixed recording noise issue while playback is active.

      We have some registers which require the device to be in full shutdown
      or to enter full shutdown before the register settings will take effect.
      Currently the driver is not shutting down the device when a new audio
      route is created. If a new audio route is made active while there is
      already an active audio route, then the required register sequencing is
      violated. A hardware shutdown toggle when creating a new audio route
      corrects the sequencing error. The device must remain in hardware
      shutdown for 40ms to allow the internal hardware core to fully shutdown.

      clockevents/drivers/timer-sp804: Migrate to new 'set-state' interface

      Migrate timer-sp driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      There are few more changes worth noticing:

      - The clockevent device was disabled by writing: 'TIMER_CTRL_32BIT |
        TIMER_CTRL_IE' to ctrl register earlier. i.e. by un-setting the
        TIMER_CTRL_ENABLE bit. Its done by writing zero now and should have
        the same effect.

      - For shutdown and resume we were writing the same value twice to the
        register (to disable the timer), which is fixed now.

      - Switching to oneshot mode was divided into two parts earlier:
        - Firstly set_mode() was writing:
          'TIMER_CTRL_32BIT | TIMER_CTRL_IE | TIMER_CTRL_ONESHOT'
          to ctrl register (device not enabled yet)
        - Then sp804_set_next_event() was enabling the device by writing
          'readl(ctrl) | TIMER_CTRL_ENABLE' to the ctrl register. This was
          unnecessarily complicated.
        - Change this to: Stop device on set_state_oneshot and configure it in
          sp804_set_next_event().

      clockevents/drivers/timer-imx-gpt: Migrate to new 'set-state' interface

      Migrate timer-imx-gpt driver to the new 'set-state' interface provided
      by clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      Also drop:
      - 'imx_timer.cem': It was caching the last state of the clockevent
        device. The same behavior can be achieved by using clockevents state
        helpers. These helpers are only required for oneshot mode as
        shutdown/resume wouldn't be done twice by the core.

      - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
        by drivers. The prints are modified to print the set-state functions
        name now to debug the driver.

      A1"), all former users of the "sh-cmt-48-gen2" platform device name are
      only supported in generic DT-only ARM multi-platform builds.  The driver

      clockevents/drivers/dw_apb_timer: Add dynamic irq flag to the timer

      Commit d2348fb6fdc6 ("tick: Dynamically set broadcast irq affinity")
      adds one excellent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the
      interrupt affinity of the broadcast interrupt to the cpu which has the
      earliest expiry time. This patch adds CLOCK_EVT_FEAT_DYNIRQ flag to
      avoid unnecessary wakeups and IPIs when the dw_apb_timer is used as
      broadcast timer.

      A simple test:
      ~ # rm /tmp/test.sh
      ~ # cat > /tmp/test.sh
      cat /proc/interrupts
      for i in `seq 10` ; do sleep $i; done
      cat /proc/interrupts
      ~ # chmod +x /tmp/test.sh
      ~ # taskset 0x2 /tmp/test.sh

      cpu0 got 69-66=3, cpu1 got 75-7=68 timer interrupts. cpu0 got 3-2=1
      broadcast timer IPIs, cpu1 got 6-4=2 broadcast timer IPIs.
      So, overall system got 3+68+1+2=74 wakeups and 1+2=3 broadcast timer
      IPIs

      This patch removes 50% wakeups and almost 100% broadcast timer IPIs!

        same state twice and so perhaps the check wasn't required.
      - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
        by drivers and it was used just to print old-state:new-state. The
        debug prints are called from mxs_irq_clear() now based on the

      mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 ms

      Since the mailbox core users hrtimers now, it can handle much higher
      resolutions. We can reduce the txpoll_period to 1 ms as the transmit
      usually takes just few microseconds.

      mailbox: switch to hrtimer for tx_complete polling

      The mailbox core uses jiffy based timer to handle polling for the
      transmit completion. If the client/protocol have/support notification
      of the last packet transmit completion via ACK packet, then we tick the
      Tx state machine immediately in the callback. However if the client
      doesn't support that mechanism we might end-up waiting for atleast a
      jiffy even though the remote is ready to receive the next request.

      This patch switches the timer used for that polling from jiffy-based
      to hrtimer-based so that we can support polling at much higher time
      resolution.

      HID: wacom: Do not repeatedly attempt to set device mode on error

      As an extension of aef3156d7, there is no sense in repeatedly calling the
      'wacom_set_report' and 'wacom_get_report' functions if they return an
      error. Getting an error from them implies that the device is out to lunch:
      either a hard error code was returned or repeated attempts at recovering
      from a "soft" error all failed. In either case, doing even more retries is
      not likely to resolve whatever is wrong.

      i2c: tegra: update CONFIG_LOAD for new conifiguration

      Once the new configuration is set on the conifg register of
      I2C controller, it is require to update the CONFIG_LOAD register
      to transfer the new SW configuration to actual HW internal
      registers that would be used in the actual logic.

      It is like, SW is programming only shadow registers through
      regular configuration and when these load_config bit fields
      are set to 1, it causes the regular/shadows registers
      configuration transferred to the HW internal active registers.
      So SW has to set these bit fields at the end of all regular
      registers configuration. And these config_load bits are HW
      auto-clear bits. HW clears these bit fields once the register
      configuration is moved to HW internal active registers. So SW
      has to wait until these bits are auto-cleared before going
      for any further programming

      This mechanism is supported on T124 and after this SoCs.

      it has the same i2c address with controller.

      For example,
      On the pxa1928 based platform, where PMIC (88pm860) is present @0x30
      address on TWSI0 interface, and if we set 0x30 as a slave address in

      Previously we only checked if the transmission queue is not full in the

      before sending the packet and remove this complex logic.

      System ports are unique identifiers in a multi-ASIC environment that
      represent all the available ports in the system. Local ports on the
      other hand, are unique only within the local ASIC.

      Since system port to local port mapping is not part of the HW-SW
      contract and since only single-ASIC configurations are currently
      supported, set an explicit 1:1 mapping by configuring the Switch System
      Port Record (SSPR) register.

      mpls: Enforce payload type of traffic sent using explicit NULL

      RFC 4182 s2 states that if an IPv4 Explicit NULL label is the only
      label on the stack, then after popping the resulting packet must be
      treated as a IPv4 packet and forwarded based on the IPv4 header. The
      same is true for IPv6 Explicit NULL with an IPv6 packet following.

      Therefore, when installing the IPv4/IPv6 Explicit NULL label routes,
      add an attribute that specifies the expected payload type for use at
      forwarding time for determining the type of the encapsulated packet
      instead of inspecting the first nibble of the packet.

       - pass index directly to bpf_perf_event_read() instead of
         MAP_KEY;

      changes in V2:
       - put atomic_long_inc_not_zero() between fdget() and fdput();
       - limit the event type to PERF_TYPE_RAW and PERF_TYPE_HARDWARE;
       - Only read the event counter on current CPU or on current
         process;
       - add new map type BPF_MAP_TYPE_PERF_EVENT_ARRAY to store the
         pointer to the struct perf_event;
       - according to the perf_event_map_fd and key, the function
         bpf_perf_event_read() can get the Hardware PMU counter value;

      Patch 5/5 is a simple example and shows how to use this new eBPF

      perf_event_get(),perf_event_read_local() when accessing events
      counters in eBPF programs

      Patch 2/5 rewrites part of the bpf_prog_array map code and make it
      more generic;

      Patch 3/5 introduces a new bpf map type. This map only stores the
      pointer to struct perf_event;

      Patch 4/5 implements function bpf_perf_event_read() that get the

      perf: add the necessary core perf APIs when accessing events counters in 
eBPF programs

      This patch add three core perf APIs:
       - perf_event_attrs(): export the struct perf_event_attr from struct
         perf_event;
       - perf_event_get(): get the struct perf_event from the given fd;
       - perf_event_read_local(): read the events counters active on the
         current CPU;
      These APIs are needed when accessing events counters in eBPF programs.

      The API perf_event_read_local() comes from Peter and I add the
      corresponding SOB.

      Merge branch 'mv88e6xxx-switchdev-fdb'

      Vivien Didelot says:

      ====================
      net: dsa: mv88e6xxx: support switchdev FDB objects

      This patchset refactors the DSA and mv88e6xxx code to use the switchdev 
FDB
      objects.

      The first two patches add minor but necessary changes to switchdev, the 
third
      one implements the switchdev glue in DSA for FDB routines, and the 
remaining
      ones refactor the FDB access functions in the mv88e6xxx code.

      Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to 
br1):

          # bridge fdb add 3c:97:0e:11:30:6e dev swp2
          # bridge fdb add 3c:97:0e:11:40:78 dev swp3
          # bridge fdb add 3c:97:0e:11:50:86 dev swp4
          # bridge fdb del 3c:97:0e:11:40:78 dev swp3
          # bridge fdb
          01:00:5e:00:00:01 dev eth0 self permanent
          01:00:5e:00:00:01 dev eth1 self permanent
          00:50:d2:10:78:15 dev swp0 master br0 permanent
          3c:97:0e:11:30:6e dev swp2 self static
          00:50:d2:10:78:15 dev swp3 master br1 permanent
          3c:97:0e:11:50:86 dev swp4 self static
          # cat /sys/kernel/debug/dsa0/atu
          # DB   T/P  Vec State Addr
          # 001  Port 004   e   3c:97:0e:11:30:6e
          # 004  Port 010   e   3c:97:0e:11:50:86

      For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for 
non-bridged
      ports and bridge groups, and the remaining will be later used by VLANs.

      This change is necessary to welcome the support for hardware VLANs (which 
will
      follow soon).

      Changes in v2:

       - remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code

       - use ether_addr_copy instead of memcpy for MAC addresses

       - constify MAC address in port_fdb_{add,del}

       - split the mv88e6xxx code refactoring into several patches

      net: dsa: mv88e6xxx: rework FDB getnext operation

      This commit adds a low level _mv88e6xxx_atu_getnext function and helpers
      to rewrite the mv88e6xxx_port_fdb_getnext operation.

      A mv88e6xxx_atu_entry structure is added for convenient access to the
      hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value.

      The previous implementation did not handle the eventual trunk mapping.
      If the related bit is set, then the ATU data register would contain the
      trunk ID, and not the port vector.

      Check this in the FDB getnext operation and do not handle it (yet).

      net: dsa: mv88e6xxx: extend fid mask

      The driver currently manages one FID per port (or bridge group), with a
      mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

      The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
      FID 0 means that multiple address databases are not being used).

      This patch changes the fid_mask for an fid_bitmap of 4096 bits.

      >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
      bridge groups (a bridge group gets the FID of its first member). The
      remaining bits will be reserved for VLAN entries.

      extcon: arizona: Ensure variables are set for headphone detection

      The detecting flag really refers to the microphone detection stage and
      as such should be cleared before arizona_identify_headphones is called.
      Also the mic flag should be set before identify headphones is called as
      well.

      MAX20751 is a multiphase power controller with internal buck converter.
      It uses VR12.0 to report the output voltage. This requires an explicit

      This patch adds an enhanced detection for control unit initiated
      reconfiguration request scope.
      The first approach assumed the scope of the reconfiguration request
      to be restricted to the path on which the message was received.
      The enhanced approach determines the full scope of the reconfiguration
      request by evaluating additional path and device selection information
      contained in the reconfiguration message.

      s390/dasd: fix failing path verification

      DASD path verification requires the usage of sleep_on_immediatly to
      ensure that no other I/O request is blocking the recovery of
      disconnected devices. But two concurrent path verification workers for
      the same device may kill each others requests due to the usage of the
      immediate sleep_on function. This may lead to unsuccessful path
      verifications.

      Prevent that two parallel path verification workers conflict with
      each other by implementing a device flag signalling a already running
      worker.

      Btrfs: add support for blkio controllers

      This attaches accounting information to bios as we submit them so the
      new blkio controllers can throttle on btrfs filesystems.

      Not much is required, we're just associating bios with blkcgs during 
clone,
      calling wbc_init_bio()/wbc_account_io() during writepages submission,
      and attaching the bios to the current context during direct IO.

      Finally if we are splitting bios during btrfs_map_bio, this attaches
      accounting information to the split.

      The end result is able to throttle nicely on single disk filesystems.  A
      little more work is required for multi-device filesystems.

      call bio_add_page() on a missing block device. To fix this,
      scrub_extent_for_parity() can just mark the sectors on the missing
      device as errors instead of attempting to read from it.

      Additionally, the code uses scrub_remap_extent() to map the extent of
      the corresponding data stripe, but the extent wasn't already mapped. If
      scrub_remap_extent() finds a missing block device, it doesn't initialize
      extent_dev, so we're left with a NULL struct btrfs_device. The solution
      is to use btrfs_map_block() directly.

      Btrfs: fix device replace of a missing RAID 5/6 device

      The original implementation of device replace on RAID 5/6 seems to have
      missed support for replacing a missing device. When this is attempted,
      we end up calling bio_add_page() on a bio with a NULL ->bi_bdev, which
      crashes when we try to dereference it. This happens because
      btrfs_map_block() has no choice but to return us the missing device
      because RAID 5/6 don't have any alternate mirrors to read from, and a
      missing device has a NULL bdev.

      The idea implemented here is to handle the missing device case
      separately, which better only happen when we're replacing a missing RAID
      5/6 device. We use the new BTRFS_RBIO_REBUILD_MISSING operation to
      reconstruct the data from parity, check it with
      scrub_recheck_block_checksum(), and write it out with
      scrub_write_block_to_dev_replace().

      Btrfs: add RAID 5/6 BTRFS_RBIO_REBUILD_MISSING operation

      The current RAID 5/6 recovery code isn't quite prepared to handle
      missing devices. In particular, it expects a bio that we previously
      attempted to use in the read path, meaning that it has valid pages
      allocated. However, missing devices have a NULL blkdev, and we can't
      call bio_add_page() on a bio with a NULL blkdev. We could do manual
      manipulation of bio->bi_io_vec, but that's pretty gross. So instead, add
      a separate path that allows us to manually add pages to the rbio.

      Btrfs: count devices correctly in readahead during RAID 5/6 replace

      Commit 5fbc7c59fd22 ("Btrfs: fix unfinished readahead thread for raid5/6
      degraded mounting") fixed a problem where we would skip a missing device
      when we shouldn't have because there are no other mirrors to read from
      in RAID 5/6. After commit 2c8cdd6ee4e7 ("Btrfs, replace: write dirty
      pages into the replace target device"), the fix doesn't work when we're
      doing a missing device replace on RAID 5/6 because the replace device is
      counted as a mirror so we're tricked into thinking we can safely skip
      the missing device. The fix is to count only the real stripes and decide
      based on that.

      Btrfs: remove misleading handling of missing device scrub

      scrub_submit() claims that it can handle a bio with a NULL block device,
      but this is misleading, as calling bio_add_page() on a bio with a NULL
      ->bi_bdev would've already crashed. Delete this, as we're about to

      Clone and extent same lock their source and target inodes in opposite 
order.
      In addition to this, the range locking in clone doesn't take ordering into

      btrfs-extent-same.

      In addition, I do a small cleanup of the locking helpers, removing a case

      Btrfs: fix defrag to merge tail file extent

      The file layout is

      [extent 1]...[extent n][4k extent][HOLE][extent x]

      extent 1~n and 4k extent can be merged during defrag, and the whole
      defrag bytes is larger than our defrag thresh(256k), 4k extent as a
      tail is left unmerged since we check if its next extent can be merged
      (the next one is a hole, so the check will fail), the layout thus can
      be

      [new extent][4k extent][HOLE][extent x]
       (1~n)

      To fix it, beside looking at the next one, this also looks at the
      previous one by checking @defrag_end, which is set to 0 when we
      decide to stop merging contiguous extents, otherwise, we can merge
      the previous one with our extent.

      Also, this makes btrfs behave consistent with how xfs and ext4 do.

      Btrfs: fix warning in backref walking

      When we do backref walking, we search firstly in queued delayed refs
      and then the on-disk backrefs, but we parse differently for shared
      references, for delayed refs we also add 'ref->root' while for on-disk
      backrefs we don't, this can prevent us from merging refs indexed
      by the same bytenr and cause find_parent_nodes() to throw a warning at
      'WARN_ON(ref->count < 0)', for example, when we have a shared data extent
      with 'ref_cnt=1' and a delayed shared data with a BTRFS_DROP_DELAYED_REF,
      that happens.

      For shared references, no matter if it's delayed or on-disk, ref->root is
      not at all used, instead it's ref->parent that really matters, so this has
      delayed refs handled as the same way as on-disk refs.

      btrfs: Fix data checksum error cause by replace with io-load.

      xfstests btrfs/070 sometimes failed.
      In my test machine, its fail rate is about 30%.
      In another vm(vmware), its fail rate is about 50%.

      Reason:
        btrfs/070 do replace and defrag with fsstress simultaneously,
        after above operation, checksum error is found by scrub.

        Actually, it have no relationship with defrag operation, only
        replace with fsstress can trigger this bug.

        New data writen to target device have possibility rewrited by
        old data from source device by replace code in debug, to avoid
        above problem, we can set target block group to readonly in
        replace period, so new data requested by other operation will
        not write to same place with replace code.

        Before patch(4.1-rc3):
          30% failed in 100 xfstests.
        After patch:
          0% failed in 300 xfstests.

      It also happened in btrfs/071 as it's another scrub with IO load tests.

       place1: if (key.objectid > logic_end) ...
       place2: if (logic_start >= logic_end) ...

       (place2 is typo, is should be ">", it is copied from other

      We can fix above typo directly, but the root reason is ambiguous
      meaning of logic_end in scrub raid56 parity.

      In other place, XXX_end is pointed to data which is not included,
      and we need to process segment of [XXX_start, XXX_end).

      But for scrub raid56 parity, logic_end is pointed to lattest data
      need to process, and introduced many "+ 1" and "- 1" in code as
      below:
       length = sparity->logic_end - sparity->logic_start + 1
       logic_end - logic_start + 1

      btrfs: Fix scrub panic when leaf crosses stripes

      Scrub panic in following operation:
        mkfs.ext4 /dev/vdh
        btrfs-convert /dev/vdh
        mount /dev/vdh /mnt/tmp1
        btrfs scrub start -B /dev/vdh
        (panic)

      Reason:
        1: In some case, leaf created by btrfs-convert was splited into 2
           strips.
        2: Scrub bypassed part of above wrong leaf data, but remain data
           caused panic in scrub_checksum_tree_block().

      For reason 1:
        we can get following information after some simple operation.
        a. mkfs.ext4 /dev/vdh
           btrfs-convert /dev/vdh
        b. btrfs-debug-tree /dev/vdh
           we can see following item in extent tree:
           item 25 key (27054080 METADATA_ITEM 0) itemoff 15083 itemsize 33
           Its logical address is [27054080, 27070464)
           and acrossed 2 strips:
           [27000832, 27066368)
           [27066368, 27131904)
        Will be fixed in btrfs-progs(btrfs-convert, btrfsck, ...)

      For reason 2:
        Scrub is trying to do a "bypass" in this case, but the result is
        "panic", because current code lacks of some condition in bypass,
        and let some wrong leaf data escaped.

      This patch fixed above scrub code.

      Before patch:
        # btrfs scrub start -B /dev/vdh
        (panic)

      After patch:
        # btrfs scrub start -B /dev/vdh
        scrub done for 353cec8f-da31-4a94-aa35-be72d997b06e

      Btrfs: fix stale dir entries after removing a link and fsync

      We have one more case where after a log tree is replayed we get
      inconsistent metadata leading to stale directory entries, due to
      some directories having entries pointing to some inode while the
      inode does not have a matching BTRFS_INODE_[REF|EXTREF]_KEY item.

      To trigger the problem we need to have a file with multiple hard links
      belonging to different parent directories. Then if one of those hard
      links is removed and we fsync the file using one of its other links
      that belongs to a different parent directory, we end up not logging
      the fact that the removed hard link doesn't exists anymore in the
      parent directory.

      Simple reproducer:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

        _cleanup()
        {

        }

        # Make sure everything done so far is durably persisted.
        sync

        # Now we remove one of our file's hardlinks in the directory testdir.
        unlink $SCRATCH_MNT/testdir/foo3

        # We now fsync our file using the "foo" link, which has a parent that
        # is not the directory "testdir".

        # link anymore and we should be able to remove all names in the
        # directory "testdir" and then remove it (no stale directory entries
        # left after the journal/log replay).
        echo "Entries in testdir:"
        ls -1 $SCRATCH_MNT/testdir

        rm -f $SCRATCH_MNT/testdir/*

Aborting unused transaction(No such entry).

      So fix this by logging all parent inodes, current and old ones, to make
      sure we do not get stale entries after log replay. This is not a simple
      solution such as triggering a full transaction commit because it would
      imply full transaction commit when an inode is fsynced in the same
      transaction that modified it and reloaded it after eviction (because its
      last_unlink_trans is set to the same value as its last_trans as of the
      commit with the title "Btrfs: fix stale dir entries after unlink, inode
      eviction and fsync"), and it would also make fstest generic/066 fail
      since one of the fsyncs triggers a full commit and the next fsync will
      not find the inode in the log anymore (therefore not removing the xattr).

      btrfs: fix search key advancing condition

      The search key advancing condition used in copy_to_sk() is loose. It can
      advance the key even if it reaches sk->max_*: e.g. when the max key = 
(512,
      1024, -1) and the current key = (512, 1025, 10), it increments the
      offset by 1, continues hopeless search from (512, 1025, 11). This issue
      make ioctl() to take unexpectedly long time scanning all the leaf a blocks
      one by one.

      This commit fix the problem using standard way of key comparison:
      btrfs_comp_cpu_keys()

      Btrfs: teach backref walking about backrefs with underflowed offset values

      When cloning/deduplicating file extents (through the clone and extent_same
      ioctls) we can get data back references with offset values that are a
      result of an unsigned integer arithmetic underflow, that is, values that
      are much larger then they could be otherwise.

      This is not a problem when decrementing or dropping the back references
      (happens when we overwrite the extents or punch a hole for example, 
through
      __btrfs_drop_extents()), since we compute the same too large offset value,
      but it is a problem for the backref walking code, used by an incremental
      send and the ioctls that are used by the btrfs tool "inspect-internal"
      commands, as it makes it miss the corresponding file extent items because
      the search key is set for an extent item that starts at an offset matching
      the exceptionally large offset value of the data back reference. For an
      incremental send this causes the send ioctl to fail with -EIO.

      So teach the backref walking code to deal with these cases by setting the
      search key's offset to 0 if the backref's offset value is larger than
      LLONG_MAX (the largest possible file offset). This makes sure the backref
      walking code finds the corresponding file extent items at the expense of
      scanning more items and leafs in the btree.

      Fixing the clone/dedup ioctls to not produce such underflowed results 
would
      require major changes breaking backward compatibility, updating user space
      tools, etc.

      Btrfs: fix stale dir entries after unlink, inode eviction and fsync

      If we remove a hard link from an inode, the inode gets evicted, then
      we fsync the inode and then power fail/crash, when the log tree is
      replayed, the parent directory inode still has entries pointing to
      the name that no longer exists, while our inode no longer has the
      BTRFS_INODE_REF_KEY item matching the deleted hard link (as expected),
      leaving the filesystem in an inconsistent state. The stale directory
      entries can not be deleted (an attempt to delete them causes -ESTALE
      errors), which makes it impossible to delete the parent directory.

      This happens because we track the id of the transaction where the last
      unlink operation for the inode happened (last_unlink_trans) in an
      in-memory only field of the inode, that is, a value that is never
      persisted in the inode item stored on the fs/subvol btree. So if an
      inode is evicted and loaded again, the value for last_unlink_trans is
      set to 0, which prevents the fsync from logging the parent directory
      at btrfs_log_inode_parent(). So fix this by setting last_unlink_trans
      to the id of the transaction that last modified the inode when we
      load the inode. This is a pessimistic approach but it always ensures
      correctness with the trade off of ocassional full transaction commits
      when an fsync is done against the inode in the same transaction where
      it was evicted and reloaded when our inode is a directory and often
      logging its parent unnecessarily when our inode is not a directory.

      The following test case for fstests triggers the problem:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$

      Btrfs: fix stale directory entries after fsync log replay

      We have another case where after an fsync log replay we get an inode with
      a wrong link count (smaller than it should be) and a number of directory
      entries greater than its link count. This happens when we add a new link
      hard link to our inode A and then we fsync some other inode B that has
      the side effect of logging the parent directory inode too. In this case
      at log replay time we add the new hard link to our inode (the item with
      key BTRFS_INODE_REF_KEY) when processing the parent directory but we
      never adjust the link count of our inode A. As a result we get stale dir
      entries for our inode A that can never be deleted and therefore it makes
      it impossible to remove the parent directory (as its i_size can never
      decrease back to 0).

      A simple reproducer for fstests that triggers this issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

        _cleanup()
        {
            _cleanup_flakey
            rm -f $tmp.*
        }

        rm -f $seqres.full

        _scratch_mkfs >>$seqres.full 2>&1
        _init_flakey
        _mount_flakey

        # Create our test directory and files.
        mkdir $SCRATCH_MNT/testdir
        touch $SCRATCH_MNT/testdir/foo
        touch $SCRATCH_MNT/testdir/bar

        # Make sure everything done so far is durably persisted.
        sync

        # Create one hard link for file foo and another one for file bar. After
        # that fsync only the file bar.
        ln $SCRATCH_MNT/testdir/bar $SCRATCH_MNT/testdir/bar_link
        ln $SCRATCH_MNT/testdir/foo $SCRATCH_MNT/testdir/foo_link
        $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/testdir/bar

        # Silently drop all writes on scratch device to simulate power failure.
        _load_flakey_table $FLAKEY_DROP_WRITES
        _unmount_flakey

        # Allow writes again and mount the fs to trigger log/journal replay.
        _load_flakey_table $FLAKEY_ALLOW_WRITES
        _mount_flakey

        # Now verify both our files have a link count of 2.
        echo "Link count for file foo: $(stat --format=%h 
$SCRATCH_MNT/testdir/foo)"
        echo "Link count for file bar: $(stat --format=%h 
$SCRATCH_MNT/testdir/bar)"

        # We should be able to remove all the links of our files in testdir, and
        # after that the parent directory should become empty and therefore
        # possible to remove it.
        rm -f $SCRATCH_MNT/testdir/*
        rmdir $SCRATCH_MNT/testdir

        _unmount_flakey

        # The fstests framework will call fsck against our filesystem which 
will verify
        # that all metadata is in a consistent state.

        status=0
        exit

      The test fails with:

       -Link count for file foo: 2
       +Link count for file foo: 1
        Link count for file bar: 2
       +rm: cannot remove 
'/home/fdmanana/btrfs-tests/scratch_1/testdir/foo_link': Stale file handle
       +rmdir: failed to remove '/home/fdmanana/btrfs-tests/scratch_1/testdir': 
Directory not empty
       (...)
       _check_btrfs_filesystem: filesystem on /dev/sdc is inconsistent

      And fsck's output:

        (...)
        checking fs roots
        root 5 inode 258 errors 2001, no inode item, link count wrong
            unresolved ref dir 257 index 5 namelen 8 name foo_link filetype 1 
errors 4, no inode ref
        Checking filesystem on /dev/sdc
        (...)

      So fix this by marking inodes for link count fixup at log replay time
      whenever a directory entry is replayed if the entry was created in the
      transaction where the fsync was made and if it points to a non-directory
      inode.

      This isn't a new problem/regression, the issue exists for a long time,
      possibly since the log tree feature was added (2008).

      If SPC = '1' and the stop endpoint command is executed, after a Short
      Packet condition has been detected, but before the end of the TD has been
      reached, (i.e. the TD is in progress for pipe), then a Transfer Event TRB
      with its Completion Code set to Stopped - Short Packet and its TRB
      Transfer Length set to value of the EDTLA shall be forced for the
      interrupted TRB, irrespective of whether its IOC or ISP flags are set.
      This Transfer Event TRB will precede the Command Completion Event TRB for
      the command, and is referred to as a Stopped Transfer Event.

      perf stat: Move perf_counts struct and functions into separate object

      Moving 'struct perf_counts' and associated functions into separate
      object, so we could remove stat.c object dependency from python build.

      It makes the python code to build properly, because it fails to load due
      to missing stat-shadow.c object dependency if some patches from Kan
      Liang are applied.

      So apply this one, then Kan's.

      iio: Add inverse unit conversion macros

      Add inverse unit conversion macro to convert from standard IIO units to
      units that might be used by some devices.

      Those are useful in combination with scale factors that are specified as
      IIO_VAL_FRACTIONAL. Typically the denominator for those specifications 
will
      contain the maximum raw value the sensor will generate and the numerator
      the value it maps to in a specific unit. Sometimes datasheets specify 
those
      in different units than the standard IIO units (e.g. degree/s instead of
      rad/s) and so we need to do a unit conversion.

      From a mathematical point of view it does not make a difference whether we
      apply the unit conversion to the numerator or the inverse unit conversion
      to the denominator since (x / y) / z = x / (y * z). But as the denominator
      is typically a larger value and we are rounding both the numerator and
      denominator to integer values using the later method gives us a better
      precision (E.g. the relative error is smaller if we round 8000.3 to 8000
      rather than rounding 8.3 to 8).

      This is where in inverse unit conversion macros will be used.

      Marked for stable as used by some upcoming fixes.

      ARM: dts: rockchip: reserve unusable memory region on rk3288

      The all current Rockchip SoCs supporting 4GB of ram have problems 
accessing
      the memory region 0xfe000000~0xff000000. This also seems to includes the
      rk3368 arm64 soc.

      All current code handling dma memory oddities I could find, seem to 
involve
      soc-specific code (zone-dma or so) while this issue is shared between 
arm32
      and arm64 socs from Rockchip, which would need to have this described in
      the soc devicetree on both socs.

      Limiting the dma-zone alone also does not solve the issue and as the
      dma-masks need to be a power-of-two in the kernel, the next lower dma-mask
      brings memory usable for dma down to 2GB.

      So as a stop-gap block off the affected region to prevent its use by
      devices with 4GB of memory, like some recent Chromebooks.

      ARM: dts: rockchip: add usb phys to Cortex-A9 socs

      This adds the usbphy nodes to rk3066 and rk3188, which share the usb hosts
      in rk3xxx.dtsi and also enables it on boards based around these socs.

      The usb-phy itself is the same as used on the rk3288 already.

      ARM: dts: rockchip: set correct dwc2 params for cortex-a9 socs

      According to the manual, the fifo sizes are the same as on later socs
      like the rk3288 and this also fixes an error about "insufficient fifo
      memory", as it seems the values read from the ip are wrong.

      x86/vdso: Emit a GNU hash

      Some dynamic loaders may be slightly faster if a GNU hash is
      available.  Strangely, this seems to have no effect at all on
      the vdso size.

      This is unlikely to have any measurable effect on the time it
      takes to resolve vdso symbols (since there are so few of them).
      In some contexts, it can be a win for a different reason: if
      every DSO has a GNU hash section, then libc can avoid
      calculating SysV hashes at all.  Both musl and glibc appear to
      have this optimization.

      It's plausible that this breaks some ancient glibc version.  If
      so, then, depending on what glibc versions break, we could
      either require COMPAT_VDSO for them or consider reverting.

      powerpc/fsl: Force coherent memory on e500mc derivatives

      In CoreNet systems it is not allowed to mix M and non-M mappings to the
      same memory, and coherent DMA accesses are considered to be M mappings
      for this purpose.  Ignoring this has been observed to cause hard
      lockups in non-SMP kernels on e6500.

      Furthermore, e6500 implements the LRAT (logical to real address table)
      which allows KVM guests to control the WIMGE bits.  This means that
      KVM cannot force the M bit on the way it usually does, so the guest had
      better set it itself.

      map_kernel() doesn't catch all places that create kernel PTEs.  In

      powerpc/85xx: Use kconfig fragments

      Unify mpc85xx and corenet configs using fragments, to ease maintenance
      and avoid the sort of drift that the previous patch fixed.

      Hardware and software options are separated, with the hope that other
      embedded platforms could share the software options, and to make it
      easier to maintain custom/alternate configs that focus on either
      hardware or software options.

      Due to the previous patch, this patch should not affect the results of
      any of the affected defconfigs -- only how those results are achieved.
      The resulting config is more or less the union of the options that any
      of the configs previously selected.  No attempt was made in this (or

      will make it easier to do so in future patches.

      PM / AVS: rockchip-io: depend on CONFIG_POWER_AVS

      The rockchip io-domain driver currently only depends on ARCH_ROCKCHIP
      itself. This makes it possible to select the power-domain driver, but
      not the POWER_AVS class and results in the iodomain-driver not getting
      build in this case.

      So add the additional dependency, which also results in the driver
      config option now being placed nicely into the AVS submenu.

      Fixes: 662a958638bd ("PM / AVS: rockchip-io: add driver handling Rockchip 
io domains")

      mtd: brcmnand: Fix misuse of IS_ENABLED

      While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
      for other symbols such as __BIG_ENDIAN that is provided directly by
      the compiler.

      Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.

      net: Fix race condition in store_rps_map

      There is a race condition in store_rps_map that allows jump label
      count in rps_needed to go below zero. This can happen when
      concurrently attempting to set and a clear map.

      Scenario:

      1. rps_needed count is zero
      2. New map is assigned by setting thread, but rps_needed count _not_ yet
         incremented (rps_needed count still zero)
      2. Map is cleared by second thread, old_map set to that just assigned
      3. Second thread performs static_key_slow_dec, rps_needed count now goes
         negative

      Fix is to increment or decrement rps_needed under the spinlock.

      Staging: fbtft: Use a struct to describe each LCD controller

      Use a struct flexfb_lcd_controller to holds chip properties, instead of
      relying on a long 'if - else if' chain.
      This allows to:
      - use a simple linear search to verify if a certain LCD controller
      model is supported or not.
      - add support for a new LCD chip controller simply defining a new
      flexfb_lcd_controller struct.

      Introduce a helper function to stop any ai conversions and reset the

      and me4000_ai_cancel().

      Use the new helper in the ai (*insn_read) to ensure that the ai control
      register is set to a known state after reading the samples.

      The ai control register will now always be '0' after the (*cancel) of
      a command or doing an (*insn_read). Knowing this the programming of
      the register for single acquisition mode in the (*insn_read) can be
      simplified.

      Sowmini Varadhan says:

      ====================
      RDS-TCP: Network namespace support

      This patch series contains the set of changes to correctly set up
      the infra for PF_RDS sockets that use TCP as the transport in multiple
      network namespaces.

      Patch 1 in the series is the minimal set of changes to allow
      a single instance of RDS-TCP to run in any (i.e init_net or other) net
      namespace.  The changes in this patch set ensure that the execution of
      'modprobe [-r] rds_tcp' sets up the kernel TCP sockets
      relative to the current netns, so that RDS applications can send/recv
      packets from that netns, and the netns can later be deleted cleanly.

      Patch 2 of the series further allows multiple RDS-TCP instances,
      one per network namespace. The changes in this patch allows dynamic
      creation/tear-down of RDS-TCP client and server sockets  across all
      current and future namespaces.

      v2 changes from RFC sent out earlier:
          David Ahern comments in patch 1, net_device notifier in patch 2,
          patch 3 broken off and submitted separately.

      RDS-TCP: Support multiple RDS-TCP listen endpoints, one per netns.

      Register pernet subsys init/stop functions that will set up
      and tear down per-net RDS-TCP listen endpoints. Unregister
      pernet subusys functions on 'modprobe -r' to clean up these
      end points.

      Enable keepalive on both accept and connect socket endpoints.
      The keepalive timer expiration will ensure that client socket
      endpoints will be removed as appropriate from the netns when
      an interface is removed from a namespace.

      Register a device notifier callback that will clean up all
      sockets (and thus avoid the need to wait for keepalive timeout)
      when the loopback device is unregistered from the netns indicating
      that the netns is getting deleted.

      Let the user explicitly provide a file containing trusted keys, instead of

      Fix applied from James Morris that removes an '=' from a macro definition

      modsign: Use single PEM file for autogenerated key

      The current rule for generating signing_key.priv and signing_key.x509 is
      a classic example of a bad rule which has a tendency to break parallel
      make. When invoked to create *either* target, it generates the other
      target as a side-effect that make didn't predict.

      So let's switch to using a single file signing_key.pem which contains
      both key and certificate. That matches what we do in the case of an
      external key specified by CONFIG_MODULE_SIG_KEY anyway, so it's also
      slightly cleaner.

      MODSIGN: Use PKCS#7 messages as module signatures

      Move to using PKCS#7 messages as module signatures because:

       (1) We have to be able to support the use of X.509 certificates that 
don't
           have a subjKeyId set.  We're currently relying on this to look up the
           X.509 certificate in the trusted keyring list.

       (2) PKCS#7 message signed information blocks have a field that supplies 
the
           data required to match with the X.509 certificate that signed it.

       (3) The PKCS#7 certificate carries fields that specify the digest 
algorithm
           used to generate the signature in a standardised way and the X.509
           certificates specify the public key algorithm in a standardised way 
- so
           we don't need our own methods of specifying these.

       (4) We now have PKCS#7 message support in the kernel for signed kexec 
purposes
           and we can make use of this.

      To make this work, the old sign-file script has been replaced with a 
program
      that needs compiling in a previous patch.  The rules to build it are added
      here.

      MODSIGN: Provide a utility to append a PKCS#7 signature to a module

      Provide a utility that:

       (1) Digests a module using the specified hash algorithm (typically 
sha256).

           [The digest can be dumped into a file by passing the '-d' flag]

       (2) Generates a PKCS#7 message that:

           (a) Has detached data (ie. the module content).

           (b) Is signed with the specified private key.

           (c) Refers to the specified X.509 certificate.

           (d) Has an empty X.509 certificate list.

           [The PKCS#7 message can be dumped into a file by passing the '-p' 
flag]

       (3) Generates a signed module by concatenating the old module, the PKCS#7
           message, a descriptor and a magic string.  The descriptor contains 
the
           size of the PKCS#7 message and indicates the id_type as 
PKEY_ID_PKCS7.

       (4) Either writes the signed module to the specified destination or 
renames
           it over the source module.

      This allows module signing to reuse the PKCS#7 handling code that was 
added
      for PE file parsing for signed kexec.

      Note that the utility is written in C and must be linked against the 
OpenSSL
      crypto library.

      Note further that I have temporarily dropped support for handling 
externally
      created signatures until we can work out the best way to do those.  
Hopefully,
      whoever creates the signature can give me a PKCS#7 certificate.

      PKCS#7: Allow detached data to be supplied for signature checking purposes

      It is possible for a PKCS#7 message to have detached data.  However, to 
verify
      the signatures on a PKCS#7 message, we have to be able to digest the data.
      Provide a function to supply that data.  An error is given if the PKCS#7
      message included embedded data.

      This is used in a subsequent patch to supply the data to module signing 
where
      the signature is in the form of a PKCS#7 message with detached data, 
whereby
      the detached data is the module content that is signed.

      X.509: Support X.509 lookup by Issuer+Serial form AuthorityKeyIdentifier

      If an X.509 certificate has an AuthorityKeyIdentifier extension that 
provides
      an issuer and serialNumber, then make it so that these are used in 
preference
      to the keyIdentifier field also held therein for searching for the signing
      certificate.

      If both the issuer+serialNumber and the keyIdentifier are supplied, then 
the
      certificate is looked up by the former but the latter is checked as well. 
 If
      the latter doesn't match the subjectKeyIdentifier of the parent 
certificate,
      EKEYREJECTED is returned.

      This makes it possible to chain X.509 certificates based on the issuer and
      serialNumber fields rather than on subjectKeyIdentifier.  This is 
necessary as
      we are having to deal with keys that are represented by X.509 certificates
      that lack a subjectKeyIdentifier.

      obfuscates the code. Remove the field and use directly enum value.

      perf tests: Add LLVM test for eBPF on-the-fly compiling

      Previous patches introduce llvm__compile_bpf() to compile source file to
      eBPF object. This patch adds testcase to test it. It also tests libbpf
      by opening generated object after applying next patch which introduces
      HAVE_LIBBPF_SUPPORT option.

      Since llvm__compile_bpf() prints long messages which users who don't
      explicitly test llvm doesn't care, this patch set verbose to -1 to
      suppress all debug, warning and error message, and hint user use 'perf
      test -v' to see the full output.

      For the same reason, if clang is not found in PATH and there's no [llvm]
      section in .perfconfig, skip this test.

      perf tools: Auto detecting kernel include options

      To help user find correct kernel include options, this patch extracts
      them from kbuild system by an embedded script kinc_fetch_script, which
      creates a temporary directory, generates Makefile and an empty dummy.o
      then use the Makefile to fetch $(NOSTDINC_FLAGS), $(LINUXINCLUDE) and
      $(EXTRA_CFLAGS) options. The result is passed to compiler script using
      'KERNEL_INC_OPTIONS' environment variable.

      Because options from kbuild contains relative path like
      'Iinclude/generated/uapi', the work directory must be changed. This is
      done by previous patch.

      perf tools: Auto detecting kernel build directory

      This patch detects kernel build directory by checking the existence of
      include/generated/autoconf.h.

      clang working directory is changed to kbuild directory if it is found,
      to help user use relative include path. Following patch will detect
      kernel include directory, which contains relative include patch so this
      workdir changing is needed.

      Users are allowed to set 'kbuild-dir = ""' manually to disable this
      checking.

      regmap: Use different lockdep class for each regmap init call

      Lockdep validator complains about recursive locking and deadlock
      when two different regmap instances are called in a nested order.
      That happens anytime a regmap read/write call needs to access
      another regmap.

      This is because, for performance reason, lockdep groups all locks
      initialized by the same mutex_init() in the same lock class.
      Therefore all regmap mutexes are in the same lock class, leading
      to lockdep "nested locking" warnings if a regmap accesses another
      regmap.

      In general, it is impossible to establish in advance the hierarchy
      of regmaps, so we make sure that each regmap init call initializes
      its own static lock_class_key. This is done by wrapping all
      regmap_init calls into macros.

      This also allows us to give meaningful names to the lock_class_key.
      For example, in rt5677 case, we have in /proc/lockdep_chains:
      irq_context: 0
      [ffffffc0018d2198] &dev->mutex
      [ffffffc0018d2198] &dev->mutex
      [ffffffc001bd7f60] rt5677:5104:(&rt5677_regmap)->_lock
      [ffffffc001bd7f58] rt5677:5096:(&rt5677_regmap_physical)->_lock
      [ffffffc001b95448] &(&base->lock)->rlock

      The above would have resulted in a lockdep recursive warning
      previously. This is not the case anymore as the lockdep validator
      now clearly identifies the 2 regmaps as separate.

      This is the core patch for supporting eBPF on-the-fly compiling, does
      the following work:

       1. Search clang compiler using search_program().

       2. Run command template defined in llvm-bpf-cmd-template option in
          [llvm] config section using read_from_pipe(). Patch of clang and
          source code path is injected into shell command using environment
          variable using force_set_env().

        Commiter notice:

        When building with DEBUG=1 we get a compiler error that gets fixed with
        the same approach described in commit b236512280fb:

          perf kmem: Fix compiler warning about may be accessing uninitialized 
variable

          The last argument to strtok_r doesn't need to be initialized, its
          just a placeholder to make this routine reentrant, but gcc doesn't 
know
          about that and complains, breaking the build, fix it by setting it to
          NULL.

      bpf tools: Load eBPF programs in object files into kernel

      This patch utilizes previous introduced bpf_load_program to load
      programs in the ELF file into kernel. Result is stored in 'fd' field in
      'struct bpf_program'.

      During loading, it allocs a log buffer and free it before return.  Note
      that that buffer is not passed to bpf_load_program() if the first
      loading try is successful. Doesn't use a statically allocated log buffer
      to avoid potention multi-thread problem.

      Instructions collected during opening is cleared after loading.

      load_program() is created for loading a 'struct bpf_insn' array into
      kernel, bpf_program__load() calls it. By this design we have a function
      loads instructions into kernel. It will be used by further patches,
      which creates different instances from a program and load them into
      kernel.

      bpf tools: Relocate eBPF programs

      If an eBPF program accesses a map, LLVM generates a load instruction
      which loads an absolute address into a register, like this:

        ld_64   r1, <MCOperand Expr:(mymap)>
        ...
        call    2

      That ld_64 instruction will be recorded in relocation section.
      To enable the usage of that map, relocation must be done by replacing
      the immediate value by real map file descriptor so it can be found by
      eBPF map functions.

      This patch to the relocation work based on information collected by
      patches:

      'bpf tools: Collect symbol table from SHT_SYMTAB section',
      'bpf tools: Collect relocation sections from SHT_REL sections'
      and
      'bpf tools: Record map accessing instructions for each program'.

      For each instruction which needs relocation, it inject corresponding
      file descriptor to imm field. As a part of protocol, src_reg is set to
      BPF_PSEUDO_MAP_FD to notify kernel this is a map loading instruction.

      This is the final part of map relocation patch. The principle of map
      relocation is described in commit message of 'bpf tools: Collect symbol
      table from SHT_SYMTAB section'.

      bpf tools: Create eBPF maps defined in an object file

      This patch creates maps based on 'map' section in object file using
      bpf_create_map(), and stores the fds into an array in 'struct
      bpf_object'.

      Previous patches parse ELF object file and collects required data, but
      doesn't play with the kernel. They belong to the 'opening' phase. This
      patch is the first patch in 'loading' phase. The 'loaded' field is
      introduced in 'struct bpf_object' to avoid loading an object twice,
      because the loading phase clears resources collected during the opening
      which becomes useless after loading. In this patch, maps_buf is cleared.

      issuing bpf syscall. The goal of these two files is to hide syscall
      completely from user. Note that bpf.c and bpf.h deal with kernel

      is not cared by of bpf.[ch].

      We first introduce bpf_create_map().

      Note that, since functions in bpf.[ch] are wrapper of sys_bpf, they
      don't use OO style naming.

      bpf tools: Record map accessing instructions for each program

      This patch records the indices of instructions which are needed to be
      relocated. That information is saved in the 'reloc_desc' field in
      'struct bpf_program'. In the loading phase (this patch takes effect in
      the opening phase), the collected instructions will be replaced by map
      loading instructions.

      Since we are going to close the ELF file and clear all data at the end
      of the 'opening' phase, the ELF information will no longer be valid in
      the 'loading' phase. We have to locate the instructions before maps are
      loaded, instead of directly modifying the instruction.

      'struct bpf_map_def' is introduced in this patch to let us know how many
      maps are defined in the object.

      This is the third part of map relocation. The principle of map relocation
      is described in commit message of 'bpf tools: Collect symbol table from
      SHT_SYMTAB section'.

      bpf_object__add_program() creates a new 'struct bpf_program' object.
      It first init a variable in stack using bpf_program__init(), then if

      bpf tools: Collect symbol table from SHT_SYMTAB section

      This patch collects symbols section. This section is useful when linking
      BPF maps.

      What 'bpf_map_xxx()' functions actually require are map's file
      descriptors (and the internal verifier converts fds into pointers to
      'struct bpf_map'), which we don't know when compiling. Therefore, we
      should make compiler generate a 'ldr_64 r1, <imm>' instruction, and
      fill the 'imm' field with the actual file descriptor when loading in
      libbpf.

      BPF programs should be written in this way:

       struct bpf_map_def SEC("maps") my_map = {
          .type = BPF_MAP_TYPE_HASH,
          .key_size = sizeof(unsigned long),
          .value_size = sizeof(unsigned long),
          .max_entries = 1000000,
       };

       SEC("my_func=sys_write")
       int my_func(void *ctx)
       {
           ...
           bpf_map_update_elem(&my_map, &key, &value, BPF_ANY);
           ...
       }

      Compiler should convert '&my_map' into a 'ldr_64, r1, <imm>'
      instruction, where imm should be the address of 'my_map'. According to
      the address, libbpf knows which map it actually referenced, and then
      fills the imm field with the 'fd' of that map created by it.

      However, since we never really 'link' the object file, the imm field is
      only a record in relocation section. Therefore libbpf should do the
      relocation:

       1. In relocation section (type == SHT_REL), positions of each such
          'ldr_64' instruction are recorded with a reference of an entry in
          symbol table (SHT_SYMTAB);

       2. From records in symbol table we can find the indics of map
          variables.

      Libbpf first record SHT_SYMTAB and positions of each instruction which
      required bu such operation. Then create file descriptor. Finally, after
      map creation complete, replace the imm field.

      This is the first patch of BPF map related stuff. It records SHT_SYMTAB
      into object's efile field for further use.

      bpf tools: Check endianness and make libbpf fail early

      Check endianness according to EHDR. Code is taken from
      tools/perf/util/symbol-elf.c.

      Libbpf doesn't magically convert missmatched endianness. Even if we swap
      eBPF instructions to correct byte order, we are unable to deal with
      endianness in code logical generated by LLVM.

      Therefore, libbpf should simply reject missmatched ELF object, and let
      LLVM to create good code.

      bpf tools: Read eBPF object from buffer

      To support dynamic compiling, this patch allows caller to pass a
      in-memory buffer to libbpf by bpf_object__open_buffer(). libbpf calls
      elf_memory() to open it as ELF object file.

      Because __bpf_object__open() collects all required data and won't need
      that buffer anymore, libbpf uses that buffer directly instead of clone a
      new buffer. Caller of libbpf can free that buffer or use it do other
      things after bpf_object__open_buffer() return.

      bpf tools: Open eBPF object file and do basic validation

      This patch defines basic interface of libbpf. 'struct bpf_object' will
      be the handler of each object file. Its internal structure is hide to
      user. eBPF object files are compiled by LLVM as ELF format. In this
      patch, libelf is used to open those files, read EHDR and do basic
      validation according to e_type and e_machine.

      All elf related staffs are grouped together and reside in efile field of
      'struct bpf_object'. bpf_object__elf_finish() is introduced to clear it.

      After all eBPF programs in an object file are loaded, related ELF
      information is useless. Close the object file and free those memory.

      The zfree() and zclose() functions are introduced to ensure setting NULL
      pointers and negative file descriptors after resources are released.

      bpf tools: Allow caller to set printing function

      By libbpf_set_print(), users of libbpf are allowed to register he/she
      own debug, info and warning printing functions. Libbpf will use those
      functions to print messages. If not provided, default info and warning
      printing functions are fprintf(stderr, ...); default debug printing
      is NULL.

      This API is designed to be used by perf, enables it to register its own
      logging functions to make all logs uniform, instead of separated
      logging level control.

      bpf tools: Introduce 'bpf' library and add bpf feature check

      This is the first patch of libbpf. The goal of libbpf is to create a
      standard way for accessing eBPF object files. This patch creates
      'Makefile' and 'Build' for it, allows 'make' to build libbpf.a and
      libbpf.so, 'make install' to put them into proper directories.
      Most part of Makefile is borrowed from traceevent.

      Before building, it checks the existence of libelf in Makefile, and deny
      to build if not found. Instead of throwing an error if libelf not found,
      the error raises in a phony target "elfdep". This design is to ensure
      'make clean' still workable even if libelf is not found.

      Because libbpf requires 'kern_version' field set for 'union bpf_attr'
      (bpfdep" is used for that dependency), Kernel BPF API is also checked
      by intruducing a new feature check 'bpf' into tools/build/feature,
      which checks the existence and version of linux/bpf.h. When building
      libbpf, it searches that file from include/uapi/linux in kernel source
      tree (controlled by FEATURE_CHECK_CFLAGS-bpf). Since it searches kernel
      source tree it reside, installing of newest kernel headers is not
      required, except we are trying to port these files to an old kernel.

      To avoid checking that file when perf building, the newly introduced
      'bpf' feature check doesn't added into FEATURE_TESTS and
      FEATURE_DISPLAY by default in tools/build/Makefile.feature, but added
      into libbpf's specific.

      I have done a small test:

        IS_ENABLED(REGMAP_ALLOW_WRITE_DEBUGFS) returns 0.

        #define REGMAP_ALLOW_WRITE_DEBUGFS 0
        IS_ENABLED(REGMAP_ALLOW_WRITE_DEBUGFS) returns 0.

        #define REGMAP_ALLOW_WRITE_DEBUGFS 1
        IS_ENABLED(REGMAP_ALLOW_WRITE_DEBUGFS) returns 1.

        #define REGMAP_ALLOW_WRITE_DEBUGFS 2
        IS_ENABLED(REGMAP_ALLOW_WRITE_DEBUGFS) returns 0.

      regulator: core: Drop regulator_list_mutex when we're done with it on 
remove

      When removing a regulator we hold regulator_list_mutex in order to
      ensure the regualtor doesn't become removed again.  However we only need
      to protect the list until we remove the regulator from the list so move
      the unlock earlier to reduce the locked region.

      This fixes the assumption that kvm_set_irq_routing is always run
      successfully by instead making it equal to the variable r which
      we use for returning in the function kvm_arch_vm_ioctl instead
      of making r equal to zero when calling this particular function
      and incorrectly making the caller of kvm_arch_vm_ioctl think
      the function has run successfully.

      netfilter: nft_limit: add per-byte limiting

      This patch adds a new NFTA_LIMIT_TYPE netlink attribute to indicate the 
type of
      limiting.

      Contrary to per-packet limiting, the cost is calculated from the packet 
path
      since this depends on the packet length.

      The burst attribute indicates the number of bytes in which the rate can be

      netfilter: nf_tables: add nft_dup expression

      This new expression uses the nf_dup engine to clone packets to a given 
gateway.
      Unlike xt_TEE, we use an index to indicate output interface which should 
be
      fine at this stage.

      Moreover, change to the preemtion-safe this_cpu_read(nf_skb_duplicated) 
from
      nf_dup_ipv{4,6} to silence a lockdep splat.

      Based on the original tee expression from Arturo Borrero Gonzalez, 
although
      this patch has diverted quite a bit from this initial effort due to the
      change to support maps.

      s390/numa: make core to node mapping data dynamic

      The core to node mapping data consumes about 2 KB bss data. To save memory
      for the non-NUMA case, make the data dynamic. In addition change the
      "core_to_node" array from "int" to "s32" which saves 1 KB also for the
      NUMA case.

      Intel Wired LAN Driver Updates 2015-08-05

      This series contains updates to i40e, i40evf and e1000e.

      Anjali adds support for x772 devices to i40e and i40evf.  With the added
      support, x772 supports offloading of the outer UDP transmit and receive
      checksum for tunneled packets.  Also supports evicting ATR filters in the
      hardware, so update the driver with this new feature set.

      Raanan provides several fixes for e1000e, first rectifies the Energy
      Efficient Ethernet in Sx code so that it only applies to parts that
      actually support EEE in Sx.  Fix whitespace and moved ICH8 related define
      to the proper context.  Fixed the ASPM locking which was reported by
      Bjorn Helgaas.  Fix a workaround implementation for systime which could
      experience a large non-linear increment of the systime value when
      checking for overflow.

      net_dbg_ratelimited: turn into no-op when !DEBUG

      The pr_debug family of functions turns into a no-op when -DDEBUG is not
      specified, opting instead to call "no_printk", which gets compiled to a
      no-op (but retains gcc's nice warnings about printf-style arguments).

      The problem with net_dbg_ratelimited is that it is defined to be a
      variant of net_ratelimited_function, which expands to essentially:

          if (net_ratelimit())
              pr_debug(fmt, ...);

      When DEBUG is not defined, then this becomes,

          if (net_ratelimit())
              ;

      This seems benign, except it isn't. Firstly, there's the obvious
      overhead of calling net_ratelimit needlessly, which does quite some book
      keeping for the rate limiting. Given that the pr_debug and
      net_dbg_ratelimited family of functions are sprinkled liberally through
      performance critical code, with developers assuming they'll be compiled
      out to a no-op most of the time, we certainly do not want this needless
      book keeping. Secondly, and most visibly, even though no debug message
      is printed when DEBUG is not defined, if there is a flood of
      invocations, dmesg winds up peppered with messages such as
      "net_ratelimit: 320 callbacks suppressed". This is because our
      aforementioned net_ratelimit() function actually prints this text in
      some circumstances. It's especially odd to see this when there isn't any
      other accompanying debug message.

      So, in sum, it doesn't make sense to have this function's current
      behavior, and instead it should match what every other debug family of
      functions in the kernel does with !DEBUG -- nothing.

      This patch replaces calls to net_dbg_ratelimited when !DEBUG with
      no_printk, keeping with the idiom of all the other debug print helpers.

      Also, though not strictly neccessary, it guards the call with an if (0)
      so that all evaluation of any arguments are sure to be compiled out.

      The second patch adds the possibility for tests to generate fragmented
      skbs.

      The third patch tests LD_ABS and LD_IND on fragmented skbs.

      The fourth patch adds the possibility to restrict the tests being run
      by specifying the name/id/range of the test(s) to run via module
      parameters.

      The fifth patch tests LD_ABS and LD_IND on non fragmented skbs with
      various sizes and alignments.

      The sixth and final patch checks that the interpreter or JIT correctly
      resets A and X to 0.

      This serie is against today's net-next tree.

      Changes in V2:

      ====================
      net/mlx5e: Driver updates 04-Aug-2015

      This patchset introduces two features to the ConnectX-4 driver: Patch 8/8
      ("Support physical port counters") exposes some hardware counters through
      ethtool. Rest of the patches are preparation and usage of what we call
      light-weight netdev open/close. Some flows that used to be in the 
ndo_open/stop
      are moved to the PCI probe/remove flows - i.e. we will make the netdev
      open/close operations more "light-weight".

      The benefits of this change are:
      1) Reduce the execution time of the stop/open operations.
      2) Avoid saving SW shadows of resource configurations that must
         persist through stop/open operations (e.g flow table steering
         rules), and avoid deleting/applying them from/to the device upon
         netdev stop/open.
      3) Avoid synchronizing threads that access those resources with the
         netdev stop/open threads.

      Instead of create/destroy the resource during netdev open/stop, This 
patchset
      changes the behavior such that upon netdev stop, traffic is redirected to 
a
      "Drop RQ" (a RQ that silently drops, at the NIC HW level all incoming 
traffic).
      After redirecting the traffic, RX/TX software resources could be 
destroyed.
      During netdev open, the RX/TX rings are created and traffic is redirected 
to
      the RX rings.

      Patchset was applied and tested over commit ba7591d ("ebpf: add skb->hash 
to
      offset map for usage in {cls, act}_bpf or filters")

      Now that TIRs, TISs and flow tables are kept alive while the netdev is

      - Obsolete the active_vlans SW shadow.
      - Do not delete/add flow table rules upon ndo_stop/open.
        In addition to simplifying the flow, this change also fastens
        the ndo_open/close operations.
      - Obsolete synchronization of threads accessing the flow tables
        with the netdev stop/open threads.

      than upon the netdev ndo_open/stop.

      Upon ndo_stop(), redirect all RX traffic to the (lately introduced)
      "Drop RQ" and then close only the RX/TX rings, leaving the TIRs,
      TISs and flow tables alive.

      net/mlx5e: Unify the RX flow

      Generally an RX packet flows through the following objects:
      Flow table --> TIR --> RQT --> RQ

      Where:
      - TIR stands for "Transport Interface Receive", defining the RSS and
        LRO paramaters.
      - RQT stands for "RQ Table", implementing the RSS indirection table.
      - RQ stands for "Receive Queue"

      For flows that do not need LRO, nor RSS, the driver made a shortcut to
      the above RX flow by pointing to the RQ directly from the TIR, yielding
      this flow:
      Flow table --> TIR --> RQ

      In this commit we remove this shortcut by "inserting" a single-RQ RQT
      between the TIR and the RQ, i.e RX packets will reach the same RQ but
      will go through an RQT of size 1, pointing to just a single RQ.

      This way the RX traffic re-direction to/from the "Drop RQ" will be more
      uniform (AKA "one flow"), as it will involve only RQTs re-direction and
      no TIRs re-direction.

      We recently changed this code from returning NULL to returning ERR_PTR.
      There are some left over NULL assignments which we can remove.  We can
      preserve the error code from ip_route_output() instead of always
      returning -ENODEV.  Also these functions use a mix of gotos and direct

      cpufreq: dt: Add support for turbo/boost mode

      With opp-v2 DT bindings, few OPPs can be used only for the boost mode.
      But using such OPPs require the boost mode to be supported by cpufreq
      driver.

      We will parse DT bindings only during ->init() and so can enable boost
      support only after registering cpufreq driver.

      This enables boost support as soon as any policy has boost/turbo OPPs
      for its CPUs.

      We don't need to disable boost support as that is done by the core, when
      the driver is unregistered.

      cpufreq: Allow drivers to enable boost support after registering driver

      In some cases it wouldn't be known at time of driver registration, if
      the driver needs to support boost frequencies.

      For example, while getting boost information from DT with opp-v2
      bindings, we need to parse the bindings for all the CPUs to know if
      turbo/boost OPPs are supported or not.

      One way out to do that efficiently is to delay supporting boost mode
      (i.e. creating /sys/devices/system/cpu/cpufreq/boost file), until the
      time OPP bindings are parsed.

      At that point, the driver can enable boost support. This can be done at
      ->init(), where the frequency table is created.

      To do that, the driver requires few APIs from cpufreq core that let him
      do this. This patch provides these APIs.

      PM / OPP: Add OPP sharing information to OPP library

      An opp can be shared by multiple devices, for example its very common
      for CPUs to share the OPPs, i.e. when they share clock/voltage rails.

      This patch adds support of shared OPPs to the OPP library.

      Instead of a single device, dev_opp will now contain a list of devices
      that use it. It also senses if the device (we are trying to initialize
      OPPs for) shares OPPs with a device added earlier and in that case we
      update the list of devices managed by OPPs instead of duplicating OPPs
      again.

      The same infrastructure will be used for the old OPP bindings, with
      later patches.

      PM / OPP: Add support to parse "operating-points-v2" bindings

      This adds support in OPP library to parse and create list of OPPs from
      operating-points-v2 bindings. It takes care of most of the properties of
      new bindings (except shared-opp, which will be handled separately).

      For backward compatibility, we keep supporting earlier bindings. We try
      to search for the new bindings first, in case they aren't present we
      look for the old deprecated ones.

      There are few things marked as TODO:
      - Support for multiple OPP tables
      - Support for multiple regulators

      They should be fixed separately.

      Later commits would add support for new OPP bindings and this would be
      required then. So, lets do it in a separate patch to make it easily
      reviewable.

      Another change worth noticing is INIT_LIST_HEAD(&opp->node). We weren't
      doing it earlier as we never tried to delete a list node before it is
      added to list. But this wouldn't be the case anymore. We might try to
      delete a node (just to reuse the same code paths), without it being
      getting added to the list.

      ACPI: fix acpi_debugfs_init prototype

      acpi_debugfs_init function is declared with return type int in
      drivers/acpi/internal.h when CONFIG_DEBUG_FS is enabled, but its
      definition in drivers/acpi/debugfs.c has return type void. This is due
      to commit aecad432fd68 ("ACPI: Cleanup custom_method debug stuff"),
      which changed the return type from int to void without updating the
      declaration.

      Fix this inconsistency by updating acpi_debugfs_init prototype.  While
      at it, include internal.h in debugfs.c so that the compiler can check
      that the declaration and definition remain compatible.

      ACPI / sysfs: Update method tracing facility.

      This patch updates the method tracing facility as the acpi_debug_trace()
      API has been updated to allow it to trace AML interpreter execution, the
      meanings and the usages of the API parameters are changed due to the
      updates.

      The new API:
      1. Uses ACPI_TRACE_ENABLED flag to indicate the enabling of the tracer;
      2. Allows tracer still can be enabled when method name is not specified so
         that the AML interpreter execution can be traced without knowing the
         method name, which is useful for kernel boot tracing;
      3. Supports arbitrary full path name, it doesn't need to be a name related
         to an entrance of acpi_evaluate_object().

      Note that the sysfs parameters are also updated so that when reading the
      attribute files, ACPICA internal settings are returned.

      In order to make the sysfs parameters (acpi.trace_state) available during
      boot, this patch adds code to bypass ACPICA semaphore/mutex invocations
      when acpi mutex utilities haven't been initialized.

      This patch doesn't update documentation of method tracing facility, it 
will
      be updated by further patches.

      audit: implement audit by executable

      This adds the ability audit the actions of a not-yet-running process.

      This patch implements the ability to filter on the executable path.  
Instead of
      just hard coding the ino and dev of the executable we care about at the 
moment
      the rule is inserted into the kernel, use the new audit_fsnotify
      infrastructure to manage this dynamically.  This means that if the 
filename
      does not yet exist but the containing directory does, or if the inode in
      question is unlinked and creat'd (aka updated) the rule will just 
continue to
      work.  If the containing directory is moved or deleted or the filesystem 
is
      unmounted, the rule is deleted automatically.  A future enhancement would 
be to
      have the rule survive across directory disruptions.

      This is a heavily modified version of a patch originally submitted by Eric
      Paris with some ideas from Peter Moody.

      audit: clean simple fsnotify implementation

      This is to be used to audit by executable path rules, but audit watches 
should
      be able to share this code eventually.

      At the moment the audit watch code is a lot more complex.  That code only
      creates one fsnotify watch per parent directory.  That 'audit_parent' in
      turn has a list of 'audit_watches' which contain the name, ino, dev of
      the specific object we care about.  This just creates one fsnotify watch
      per object we care about.  So if you watch 100 inodes in /etc this code
      will create 100 fsnotify watches on /etc.  The audit_watch code will
      instead create 1 fsnotify watch on /etc (the audit_parent) and then 100
      individual watches chained from that fsnotify mark.

      We should be able to convert the audit_watch code to do one fsnotify
      mark per watch and simplify things/remove a whole lot of code.  After
      that conversion we should be able to convert the audit_fsnotify code to
      support that hierarchy if the optimization is necessary.

      Move the access to the entry for audit_match_signal() to the beginning of
      the audit_del_rule() function in case the entry found is the same one 
passed
      in.  This will enable it to be used by audit_autoremove_mark_rule(),
      kill_rules() and audit_remove_parent_watches().

      This is a heavily modified and merged version of two patches originally
      submitted by Eric Paris.

      perf tools: Validate config term maximum value

      Currently the value of a PMU config term is silently truncated if it is
      too big. This is an impediment to validating the value for other
      criteria later on i.e.  the user provides an invalid value that gets
      truncated to a valid one.

      The maximum value validation is only done for the parser where the error
      is passed back to the user. In other cases the silent truncation
      continues so as not to affect tools that perhaps rely on it.

      perf annotate: Compute IPC and basic block cycles

      Compute the IPC and the basic block cycles for the annotate display.

      IPC is computed by counting the instructions, and then dividing the
      accounted cycles by that count.

      The actual IPC computation can only be done at annotate time, because we
      need to parse the objdump output first to know the number of
      instructions in the basic block.

      The cycles/IPC are also put into the perf function annotation so that
      the display code can show them.

      Again basic block overlaps are not handled, with the longest winning,
      but there are some heuristics to hide the IPC when the longest is not
      the most common.

      v2: Compute IPC correctly.

      perf report: Add infrastructure for a cycles histogram

      This adds the basic infrastructure to keep track of cycle counts per
      basic block for annotate. We allocate an array similar to the normal
      accounting, and then account branch cycles there.

      We handle two cases:

      cycles per basic block with start and cycles per branch (these are later
      used for either IPC or just cycles per BB)

      In the start case we cannot handle overlaps, so always the longest basic
      block wins.

      For the cycles per branch case everything is accurately accounted.

      v2: Remove unnecessary checks. Slight restructure. Move
      symbol__get_annotation to another patch. Move histogram allocation.
      v3: Merged with current tree

      perf tools: Add support for cycles, weight branch_info field

      cycles is a new branch_info field available on some CPUs that indicates
      the time deltas between branches in the LBR.

      Add a sort key and output code for the cycles to allow to display the
      basic block cycles individually in perf report.

      We also pass in the cycles for weight when LBRs are processed, which
      allows to get global and local weight, to get an estimate of the total
      cost.

      And also print the cycles information for perf report -D.  I also added
      printing for the previously missing LBR flags (mispredict etc.)

      scripts/kernel-doc Allow struct arguments documentation in struct body

      Describing arguments at top of a struct definition works fine
      for small/medium size structs, but it definitely doesn't work well
      for struct with a huge list of elements.

      Keeping the arguments list inside the struct body makes it easier
      to maintain the documentation.
      ie:
      /**
       * struct my_struct - short description
       * @a: first member
       * @b: second member
       *
       * Longer description
       */
      struct my_struct {
          int a;
          int b;
          /**
           * @c: This is longer description of C
           *
           * You can use paragraphs to describe arguments
           * using this method.
           */
          int c;
      };

      This patch allows the use of this kind of syntax. Only one argument
      per comment and user can use how many paragraphs he needs. It should
      start with /**, which is already being used by kernel-doc. If those
      comment doesn't follow those rules, it will be ignored.

      tracing, perf: Implement BPF programs attached to uprobes

      By copying BPF related operation to uprobe processing path, this patch
      allow users attach BPF programs to uprobes like what they are already
      doing on kprobes.

      After this patch, users are allowed to use PERF_EVENT_IOC_SET_BPF on a
      uprobe perf event. Which make it possible to profile user space programs
      and kernel events together using BPF.

      Because of this patch, CONFIG_BPF_EVENTS should be selected by
      CONFIG_UPROBE_EVENT to ensure trace_call_bpf() is compiled even if
      KPROBE_EVENT is not set.

      bpf: Use correct #ifdef controller for trace_call_bpf()

      Commit e1abf2cc8d5d80b41c4419368ec743ccadbb131e ("bpf: Fix the build on
      BPF_SYSCALL=y && !CONFIG_TRACING kernels, make it more configurable")
      updated the building condition of bpf_trace.o from CONFIG_BPF_SYSCALL
      to CONFIG_BPF_EVENTS, but the corresponding #ifdef controller in
      trace_events.h for trace_call_bpf() was not changed. Which, in theory,
      is incorrect.

      With current Kconfigs, we can create a .config with CONFIG_BPF_SYSCALL=y
      and CONFIG_BPF_EVENTS=n by unselecting CONFIG_KPROBE_EVENT and
      selecting CONFIG_BPF_SYSCALL. With these options, trace_call_bpf() will
      be defined as an extern function, but if anyone calls it a symbol missing
      error will be triggered since bpf_trace.o was not built.

      This patch changes the #ifdef controller for trace_call_bpf() from
      CONFIG_BPF_SYSCALL to CONFIG_BPF_EVENTS. I'll show its correctness:

      Before this patch:

         BPF_SYSCALL   BPF_EVENTS   trace_call_bpf   bpf_trace.o
         y             y           normal           compiled
         n             n           inline           not compiled
         y             n           normal           not compiled (incorrect)
         n             y          impossible (BPF_EVENTS depends on BPF_SYSCALL)

      After this patch:

         BPF_SYSCALL   BPF_EVENTS   trace_call_bpf   bpf_trace.o
         y             y           normal           compiled
         n             n           inline           not compiled
         y             n           inline           not compiled (fixed)
         n             y          impossible (BPF_EVENTS depends on BPF_SYSCALL)

      So this patch doesn't break anything. QED.

      mtd: spi-nor: fsl-quadspi: i.MX6SX: fixed the random QSPI access failed 
issue

      We found there is a low probability(5%) QSPI access timeout issue,
      usually it happened on kernel boot stage, the first time kernel tried to
      access QSPI chip. The READ_ID command was sent but not executed,
      consequently the probe function failed.

      The root cause is that the divider is not glitchless in i.MX6SX chip.
      If qspi clock enabled then change clock frequency by call clk_set_rate,
      there will be glitch at low possiblity rate and pass to qspi controller.
      The controler will be hang by this glitch.

      Based on the new clock flag(CLK_SET_RATE_GATE) and new framework, we
      need to change the approach of seting clock rate.
      1. Disable clock.
      2. call clk_set_rate.
      3. Enable clock again.

      mtd: spi-nor: fsl-quadspi: dynamically map memory space for AHB read

      QSPI may failed to map enough memory (256MB) for AHB read in
      previous implementation, especially in 3G/1G memory layout kernel.
      Dynamically map memory to avoid such issue.

      This implementation generally map QUADSPI_MAX_IOMAP (default 4MB) memory
      for AHB read, it should be enough for common scenarios, and the side
      effect (0.6% performance drop) is minor.

      perf trace: Add total time column to summary.

      It is cumbersome to manually calculate the total time spent in a given
      syscall by multiplying the average value with the number of calls.

      Instead, we now do this directly inside perf trace.

      Note that this is also done by 'strace', which even adds a column with
      relative numbers - something we could do in the future.

      Example:

        perf trace -s find /some/folder > /dev/null

      iommu/io-pgtable-arm: Centralise sync points

      With all current users now opted in to DMA API operations, make the
      iommu_dev pointer mandatory, rendering the flush_pgtable callback
      redundant for cache maintenance. However, since the DMA calls could be
      nops in the case of a coherent IOMMU, we still need to ensure the page
      table updates are fully synchronised against a subsequent page table
      walk. In the unmap path, the TLB sync will usually need to do this
      anyway, so just cement that requirement; in the map path which may
      consist solely of cacheable memory writes (in the coherent case),
      insert an appropriate barrier at the end of the operation, and obviate
      the need to call flush_pgtable on every individual update for
      synchronisation.

      iommu/io-pgtable-arm: Allow appropriate DMA API use

      Currently, users of the LPAE page table code are (ab)using dma_map_page()
      as a means to flush page table updates for non-coherent IOMMUs. Since
      from the CPU's point of view, creating IOMMU page tables *is* passing
      DMA buffers to a device (the IOMMU's page table walker), there's little
      reason not to use the DMA API correctly.

      Allow IOMMU drivers to opt into DMA API operations for page table
      allocation and updates by providing their appropriate device pointer.
      The expectation is that an LPAE IOMMU should have a full view of system
      memory, so use streaming mappings to avoid unnecessary pressure on
      ZONE_DMA, and treat any DMA translation as a warning sign.

      drm: Add top level Kconfig option for DRM fbdev emulation

      Legacy fbdev emulation support via DRM is achieved through KMS FB helpers.
      Most modesetting drivers enable provide fbdev emulation by default by
      selecting KMS FB helpers. A few provide a separate Kconfig option for the
      user to enable or disbale fbdev emulation.

      Enabling fbdev emulation is finally a distro-level decision. Having a top
      level Kconfig option for fbdev emulation helps by providing a uniform way
      to enable/disable fbdev emulation for any modesetting driver. It also lets
      us remove unnecessary driver specific Kconfig options that causes bloat.

      With a top level Kconfig in place, we can stub out the fb helper functions
      when not needed without breaking functionality. Having stub functions also
      prevents drivers to require wrapping fb helper function calls with 
#ifdefs.

      DRM_FBDEV_EMULATION defaults to y since many drivers enable fbdev
      emulation by default and majority of distributions expect the fbdev
      interface in the kernel.

      As of commit 5ea1f752ae04be40 ("drm: add

      drm_fb_helper_restore_fbdev_mode() is no longer public, and drivers
      should call drm_fb_helper_restore_fbdev_mode_unlocked() from their
      ->lastclose callbacks instead.

      we started checking the locking in drm_for_each_connector but somehow
      I totally missed drm_mode_config_reset. There's no problem there since
      this function should only be called in single-threaded contexts
      (driver load or resume), so just wrap the loop with the right lock.

      drm/fb-helper: Stop using trylocks in force_restore

      Since the panic handling is gone this is only used for force-restoring
      the fbdev/fbcon from sysrq, and that's done with a work item. No need
      any more to do trylocks, we can just do normal locking.

      drm/fbdev: Return -EBUSY when oopsing

      Trying to do anything with kms drivers when oopsing has become a
      failing proposition. But since we can end up in the fbdev code simply
      due to the console unblanking that's done unconditionally just
      removing our panic handler isn't enough. We need to block all fbdev
      callbacks when oopsing.

      There was already one in the blank handler, but it failed silently.
      That makes it impossible for drivers (like i915) who subclass these
      functions to figure this out.

      Instead consistently return -EBUSY so that everyone knows that we
      really don't want to be bothered right now. This also allows us to
      remove a pile of FIXMEs from the i915 fbdev code (since due to the
      failure code they now won't attempt to grab dangerous locks any more).

      There are some drivers that call alloc_apertures after framebuffer_alloc

      ARM: rockchip: set correct stabilization thresholds in suspend

      Currently the stabilization thresholds for the oscillator and external pmu
      are statically set to 30ms based on a 32kHz clock rate. This leaves out 
the
      case when we don't switch to the 32kHz clock when only entering the 
shallow
      suspend mode where the logic keeps running.

      So, set the correct threshold after we have determined if we switch to the
      32kHz clock or stay with the 24MHz one. Also set the oscillator-
      stabilization to 0 if it is kept running during suspend, as it of course
      does not need to stabilize then.

      The variable name is misleading, as the deep suspend mode always switches
      the main supplying clock to the 32kHz source. Additionally the main
      oscillator remains running in some cases, which this var indicates.

      So rename it to osc_disable to clarity.

      clockevents/drivers/em_sti: Migrate to new 'set-state' interface

      Migrate em_sti driver to the new 'set-state' interface provided by
      the clockevents core, the earlier 'set-mode' interface is marked
      obsolete now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      NOTE: This also drops a special check:

        if (old_mode == CLOCK_EVT_MODE_ONESHOT)
                em_sti_stop(p, USER_CLOCKEVENT);

      as it doesn't look like that important. This driver only supports
      ONESHOT and we can only move only to SHUTDOWN from ONESHOT and.
      Also on second call (on shutdown), em_sti_stop() would return without

      ASoC: rl6231: Simplify DMIC divider calculation expression

      Existing implementation checks all divider values and tracks
      'red' proximity value for the frequency.

      But as divider array is monotonically increasing the first
      divider that gives DMIC rate in 3MHz range is the best one
      we should use. No need for 'red' zone tracking.

      Additionally make sure that DMIC frequency is higher 1MHz.

      ARM: ux500: simplify secondary CPU boot

      This removes a lot of ancient cruft from the Ux500 SMP boot.
      Instead of the pen grab/release, just point the ROM to
      secondary_boot() and start the second CPU there, then send
      the IPI.

      Use our own SMP enable method. This enables us to remove the
      last static mapping and get both CPUs booting properly.

      Tested this and it just works.

      ARM: dts: am437x-gp-evm: Add regulator-always-on and regulator-boot-on 
for RTC DCDCs

      DCDC5 and DCDC6 supply rtc and need to be on for accessing the module.

      On A1 revision of the TPS65218, FSEAL bit would be undefined without
      coin-cell present which in many cases led to it being set, causing DCDC5
      and DCDC6 to stay active, but also leading to unexplained failures when
      it was not. On B1 revision, FSEAL is always 0 when no coin-cell is present
      so this patch is required on boards with B1 revision to ever work. This
      implementation works on boards with either A1 or B1 revision and makes
      sure that DCDC5 and DCDC6 always stay active.

      mwifiex: add missing skb_push() in mwifiex_check_uap_capabilties

      For PCIe/USB chipsets, preallocated skb buffers are reused for
      event handling. mwifiex_check_uap_capabilties() performs
      skb_pull(). This patch adds missing skb_push() to restore skb's
      data pointer/length.

      mwifiex: corrections in PCIe event skb handling

      Preallocated event SKBs are getting reused for PCIe chipset.
      Their physical addresses are shared with firmware so that
      firmware can write data into them.

      This patch makes sure that SKB is cleared and length is set to
      default while submitting it to firmware.

      mwifiex: fix system crash observed during initialisation

      System crash was observed if one of the driver initialisation
      commands is timed out. The reason is our timeout handler triggers
      firmware dump, meanwhile driver initialisation error paths have
      already freed the adapter structure.

      Firmware hasn't yet completely initialized. So collecting firmware
      dump is not needed in this case. Command timeout handler is
      modified in this patch to fix the crash issue.

      When WLAN interface is up and running, driver unload and

      We enable Rx data by updating RX ring read pointer in
      init_fw_port(). It should be done when FW is completely

      mwifiex: simplify mwifiex_complete_cmd

      600f5d909a54("mwifiex: cleanup ioctl wait queue and abstraction layer")
      introduced the wakeup_interruptible suppression in mwifiex_complete_cmd
      b1a47aa5e1e1("mwifiex: fix system hang issue in cmd timeout error case")
      then added wakup_interruptible to mwifiex_cmd_timeout_func the single
      place setting a status of ETIMEDOUT.
      Instead of doing extra work, using the standard call-chain will have the
      same effect:
      mwifiex_cancel_pending_ioctl
      -> mwifiex_recycle_cmd_node
      -> mwifiex_insert_cmd_to_free_q
      -> mwifiex_complete_cmd
      -> wake_up_interruptible

      The difference is that previously the condition was not set to true,
      but that's probably just an oversight in b1a47aa5e1e1 and shouldn't
      have any consequence

      mwifiex: remove CMD_F_CANCELED flag

      CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
      case it already started or starts processing the cmd.
      But this was probably not working the way intended:
      - it is racy: mwifiex_process_cmdresp might already have passed that
        test and is continuing to use the cmd node being recycled
      - mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
        we just set to NULL
      - mwifiex_recycle_cmd_node will clear the flag

      The reason why it probably works is that mwifiex_cancel_pending_ioctl
      is only called from mwifiex_cmd_timeout_func, where the there is little
      chance of a command response still arriving

      Allow network stack part of Rx processing to run on separate core,
      relaxing CPU utilization on the core used for Rx NAPI.

      If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
      to enable RPS. The core for processing the rx skb is determined by RPS
      mechanism according to rx_cpus bit mask which is configured at user level.
      For processing skbs on different core from the core which processes
      the interrupts, it is recommended not to enable core 0 in rx_cpus bit 
mask.

      The test flow is like below:
      1. pwrite foo -S 0xaa 0 64K
      2. pwrite foo -S 0xbb 64K 61K
      3. sync

      5. truncate foo 125K
      6. fsync foo
      7. flakey drop writes
      8. umount

      After this test, we expect the data of recovered file will have the first
      64k of data filling with value 0xaa and the next 61k of data filling with
      value 0x00 because we have fsynced it before dropping writes in dm.

      In f2fs, during recovering, we will only recover the valid block address
      in direct node page if it is marked as a fsynced dnode, but block address
      which means invalid/reserved (with value NULL_ADDR/NEW_ADDR) will not be
      recovered. So, the file recovered shows its incorrect data 0xbb in range 
of
      [61k, 125k].

      In this patch, we fix to recover invalid/reserved block during recover 
flow.

      powerpc/powernv: Invoke opal_cec_reboot2() on unrecoverable machine check 
errors.

      On non-recoverable MCE errors in kernel space, Linux kernel panics
      and system reboots. On BMC based system opal-prd runs as a daemon
      in the host. Hence, kernel crash may prevent opal-prd to detect and
      analyze this MCE error. This may land us in a situation where the faulty
      memory never gets de-configured and Linux would keep hitting same MCE 
error
      again and again. If this happens in early stage of kernel initialization,
      then Linux will keep crashing and rebooting in a loop.

      This patch fixes this issue by invoking new opal_cec_reboot2() call with
      reboot type OPAL_REBOOT_PLATFORM_ERROR to inform BMC/OCC about this
      error, so that BMC can collect relevant data for error analysis and
      decide what component to de-configure before rebooting.

      This patch is dependent on OPAL patchset posted on skiboot mailing list
      at https://lists.ozlabs.org/pipermail/skiboot/2015-July/001771.html that
      introduces opal_cec_reboot2() opal call.

      The current API allows the driver to accelerate memset by using the DMA

      However, it does so over a contiguous memory area, which might proves
      inefficient when you have to do it over a non-contiguous yet repititive
      pattern, since you have to create a number of descriptors and then submit
      each other.

      Explicitly use a vanilla ioremap() for this short lived mapping.

      driver core: correct device's shutdown order

      Now device's shutdown sequence is performed in reverse order of their
      registration in devices_kset list and this sequence corresponds to the
      reverse device's creation order. So, devices_kset data tracks
      "parent<-child" device's dependencies only.

      Unfortunately, that's not enough and causes problems in case of
      implementing board's specific shutdown procedures. For example [1]:
      "DRA7XX_evm uses PCF8575 and one of the PCF output lines feeds to
      MMC/SD and this line should be driven high in order for the MMC/SD to
      be detected. This line is modelled as regulator and the hsmmc driver
      takes care of enabling and disabling it. In the case of 'reboot',
      during shutdown path as part of it's cleanup process the hsmmc driver
      disables this regulator. This makes MMC boot not functional."

      To handle this issue the .shutdown() callback could be implemented
      for PCF8575 device where corresponding GPIO pins will be configured to
      states, required for correct warm/cold reset. This can be achieved
      only when all .shutdown() callbacks have been called already for all
      PCF8575's consumers. But devices_kset is not filled correctly now:

      devices_kset: Device61 4e000000.dmm
      devices_kset: Device62 48070000.i2c
      devices_kset: Device63 48072000.i2c
      devices_kset: Device64 48060000.i2c
      devices_kset: Device65 4809c000.mmc
      ...
      devices_kset: Device102 fixedregulator-sd
      ...
      devices_kset: Device181 0-0020 // PCF8575
      devices_kset: Device182 gpiochip496
      devices_kset: Device183 0-0021 // PCF8575
      devices_kset: Device184 gpiochip480

      As can be seen from above .shutdown() callback for PCF8575 will be called
      before its consumers, which, in turn means, that any changes of PCF8575
      GPIO's pins will be or unsafe or overwritten later by GPIO's consumers.
      The problem can be solved if devices_kset list will be filled not only
      according device creation order, but also according device's probing
      order to track "supplier<-consumer" dependencies also.

      Hence, as a fix, lets add devices_kset_move_last(),
      devices_kset_move_before(), devices_kset_move_after() and call them
      from device_move() and also add call of devices_kset_move_last() in
      really_probe(). After this change all entries in devices_kset will
      be sorted according to device's creation ("parent<-child") and
      probing ("supplier<-consumer") order.

      devices_kset after:
      devices_kset: Device121 48070000.i2c
      devices_kset: Device122 i2c-0
      ...
      devices_kset: Device147 regulator.24
      devices_kset: Device148 0-0020
      devices_kset: Device149 gpiochip496
      devices_kset: Device150 0-0021
      devices_kset: Device151 gpiochip480
      devices_kset: Device152 0-0019
      ...
      devices_kset: Device372 fixedregulator-sd
      devices_kset: Device373 regulator.29
      devices_kset: Device374 4809c000.mmc
      devices_kset: Device375 mmc0

      nvmem: Add a simple NVMEM framework for consumers

      This patch adds just consumers part of the framework just to enable easy
      review.

      Up until now, nvmem drivers were stored in drivers/misc, where they all
      had to duplicate pretty much the same code to register a sysfs file,
      allow in-kernel users to access the content of the devices they were
      driving, etc.

      This was also a problem as far as other in-kernel users were involved,
      since the solutions used were pretty much different from on driver to
      another, there was a rather big abstraction leak.

      This introduction of this framework aims at solving this. It also
      introduces DT representation for consumer devices to go get the data they
      require (MAC Addresses, SoC/Revision ID, part numbers, and so on) from
      the nvmems.

      Having regmap interface to this framework would give much better
      abstraction for nvmems on different buses.

      auxdisplay: ks0108: fix refcount

      parport_find_base() will implicitly do parport_get_port() which
      increases the refcount. Then parport_register_device() will again
      increment the refcount. But while unloading the module we are only
      doing parport_unregister_device() decrementing the refcount only once.
      We add an parport_put_port() to neutralize the effect of
      parport_get_port().

      coresight-etm3x: Support context-ID tracing when PID namespace is enabled

      The Coresight ETM drivers already support context-ID tracing, but it won't
      work when PID namespace is enabled. This is because when using PID
      namespace a process id (ie. VPID) seen from the current namespace differs
      from the id (ie. PID) seen by kernel.

      So when users write the process id seen by themselves to ETM, there needs
      to be a translation from VPID to PID, as such ETM drivers will write the
      PID into the Context ID register correctly.

      The problems with it are:

      - It is not documented.

      - The GPIO connection is described with a custom property and uses Linux
      GPIO numbering.

      - The UART connection is described using the Linux tty device name.

      xprtrdma: take HCA driver refcount at client

      This is a rework of the following patch sent almost a year back:
      http://www.mail-archive.com/linux-rdma%40vger.kernel.org/msg20730.html

      In presence of active mount if someone tries to rmmod vendor-driver, the
      command remains stuck forever waiting for destruction of all rdma-cm-id.
      in worst case client can crash during shutdown with active mounts.

      The existing code assumes that ia->ri_id->device cannot change during
      the lifetime of a transport. xprtrdma do not have support for
      DEVICE_REMOVAL event either. Lifting that assumption and adding support
      for DEVICE_REMOVAL event is a long chain of work, and is in plan.

      The community decided that preventing the hang right now is more
      important than waiting for architectural changes.

      Thus, this patch introduces a temporary workaround to acquire HCA driver
      module reference count during the mount of a nfs-rdma mount point.

      xprtrdma: Fix large NFS SYMLINK calls

      Repair how rpcrdma_marshal_req() chooses which RDMA message type
      to use for large non-WRITE operations so that it picks RDMA_NOMSG
      in the correct situations, and sets up the marshaling logic to
      SEND only the RPC/RDMA header.

      Large NFSv2 SYMLINK requests now use RDMA_NOMSG calls. The Linux NFS
      server XDR decoder for NFSv2 SYMLINK does not handle having the
      pathname argument arrive in a separate buffer. The decoder could be
      fixed, but this is simpler and RDMA_NOMSG can be used in a variety
      of other situations.

      Ensure that the Linux client continues to use "RDMA_MSG + read
      list" when sending large NFSv3 SYMLINK requests, which is more
      efficient than using RDMA_NOMSG.

      Large NFSv4 CREATE(NF4LNK) requests are changed to use "RDMA_MSG +
      read list" just like NFSv3 (see Section 5 of RFC 5667). Before,
      these did not work at all.

      xprtrdma: Fix XDR tail buffer marshalling

      Currently xprtrdma appends an extra chunk element to the RPC/RDMA
      read chunk list of each NFSv4 WRITE compound. The extra element
      contains the final GETATTR operation in the compound.

      The result is an extra RDMA READ operation to transfer a very short
      piece of each NFS WRITE compound (typically 16 bytes). This is
      inefficient.

      It is also incorrect.

      The client is sending the trailing GETATTR at the same Position as
      the preceding WRITE data payload. Whether or not RFC 5667 allows
      the GETATTR to appear in a read chunk, RFC 5666 requires that these
      two separate RPC arguments appear at two distinct Positions.

      It can also be argued that the GETATTR operation is not bulk data,
      and therefore RFC 5667 forbids its appearance in a read chunk at
      all.

      Although RFC 5667 is not precise about when using a read list with
      NFSv4 COMPOUND is allowed, the intent is that only data arguments
      not touched by NFS (ie, read and write payloads) are to be sent
      using RDMA READ or WRITE.

      The NFS client constructs GETATTR arguments itself, and therefore is
      required to send the trailing GETATTR operation as additional inline
      content, not as a data payload.

      NB: This change is not backwards compatible. Some older servers do
      not accept inline content following the read list. The Linux NFS
      server should handle this content correctly as of commit
      a97c331f9aa9 ("svcrdma: Handle additional inline content").

      xprtrdma: Don't provide a reply chunk when expecting a short reply

      Currently Linux always offers a reply chunk, even when the reply
      can be sent inline (ie. is smaller than 1KB).

      On the client, registering a memory region can be expensive. A
      server may choose not to use the reply chunk, wasting the cost of
      the registration.

      This is a change only for RPC replies smaller than 1KB which the
      server constructs in the RPC reply send buffer. Because the elements
      of the reply must be XDR encoded, a copy-free data transfer has no
      benefit in this case.

      xprtrdma: Always provide a write list when sending NFS READ

      The client has been setting up a reply chunk for NFS READs that are
      smaller than the inline threshold. This is not efficient: both the
      server and client CPUs have to copy the reply's data payload into
      and out of the memory region that is then transferred via RDMA.

      Using the write list, the data payload is moved by the device and no
      extra data copying is necessary.

      xprtrdma: Account for RPC/RDMA header size when deciding to inline

      When the size of the RPC message is near the inline threshold (1KB),
      the client would allow messages to be sent that were a few bytes too
      large.

      When marshaling RPC/RDMA requests, ensure the combined size of
      RPC/RDMA header and RPC header do not exceed the inline threshold.
      Endpoints typically reject RPC/RDMA messages that exceed the size
      of their receive buffers.

      The two server implementations I test with (Linux and Solaris) use
      receive buffers that are larger than the clientâ??s inline threshold.
      Thus so far this has been benign, observed only by code inspection.

      xprtrdma: Remove logic that constructs RDMA_MSGP type calls

      RDMA_MSGP type calls insert a zero pad in the middle of the RPC
      message to align the RPC request's data payload to the server's
      alignment preferences. A server can then "page flip" the payload
      into place to avoid a data copy in certain circumstances. However:

      1. The client has to have a priori knowledge of the server's
         preferred alignment

      2. Requests eligible for RDMA_MSGP are requests that are small
         enough to have been sent inline, and convey a data payload
         at the _end_ of the RPC message

      Today 1. is done with a sysctl, and is a global setting that is
      copied during mount. Linux does not support CCP to query the
      server's preferences (RFC 5666, Section 6).

      A small-ish NFSv3 WRITE might use RDMA_MSGP, but no NFSv4
      compound fits bullet 2.

      Thus the Linux client currently leaves RDMA_MSGP disabled. The
      Linux server handles RDMA_MSGP, but does not use any special
      page flipping, so it confers no benefit.

      Clean up the marshaling code by removing the logic that constructs
      RDMA_MSGP type calls. This also reduces the maximum send iovec size
      from four to just two elements.

      /proc/sys/sunrpc/rdma_inline_write_padding is a kernel API, and
      thus is left in place.

      xprtrdma: Remove last ib_reg_phys_mr() call site

      All HCA providers have an ib_get_dma_mr() verb. Thus
      rpcrdma_ia_open() will either grab the device's local_dma_key if one
      is available, or it will call ib_get_dma_mr(). If ib_get_dma_mr()
      fails, rpcrdma_ia_open() fails and no transport is created.

      Therefore execution never reaches the ib_reg_phys_mr() call site in
      rpcrdma_register_internal(), so it can be removed.

      The remaining logic in rpcrdma_{de}register_internal() is folded
      into rpcrdma_{alloc,free}_regbuf().

      This is clean up only. No behavior change is expected.

      xprtrdma: Don't fall back to PHYSICAL memory registration

      PHYSICAL memory registration uses a single rkey for all of the
      client's memory, thus is insecure. It is still useful in some cases
      for testing.

      Retain the ability to select PHYSICAL memory registration capability
      via /proc/sys/sunrpc/rdma_memreg_strategy, but don't fall back to it
      if the HCA does not support FRWR or FMR.

      This means amso1100 no longer works out of the box with NFS/RDMA.
      When using amso1100 HCAs, set the memreg_strategy sysctl to 6 before
      performing NFS/RDMA mounts.

      usb: ehci-platform: Fix using multiple controllers from OF

      When using OF defined controllers the platform data struct is shared
      between all devices, so it can't be used for device specific settings.
      However it is currently used for the OF properties
      needs-reset-on-resume and has-transaction-translator.

      To fix this issue move setting hcd->has_tt to the probe and
      move pdata->reset_on_resume to the private data.

      IRQ_DOMAIN is a hidden config option, so depending on it doesn't
      make any sense. Select the config option because it's required to

      spmi: add command tracepoints for SPMI

      Add tracepoints to retrieve information about read, write
      and non-data commands. For performance measurement support
      tracepoints are added at the beginning and at the end of
      transfers. Following is a list showing the new tracepoint
      events. The "cmd" parameter here represents the opcode, SID,
      and full 16-bit address.

      spmi_write_begin: cmd and data buffer.
      spmi_write_end  : cmd and return value.
      spmi_read_begin : cmd.
      spmi_read_end   : cmd, return value and data buffer.
      spmi_cmd        : cmd.

      The reason that cmd appears at both the beginning and at
      the end event is that SPMI drivers can request commands
      concurrently. cmd helps in matching the corresponding
      events.

      SPMI tracepoints can be enabled like:

      echo 1 >/sys/kernel/debug/tracing/events/spmi/enable

      and will dump messages that can be viewed in
      /sys/kernel/debug/tracing/trace that look like:

      ... spmi_read_begin: opc=56 sid=00 addr=0x0000
      ... spmi_read_end: opc=56 sid=00 addr=0x0000 ret=0 len=02 buf=0x[01-40]
      ... spmi_write_begin: opc=48 sid=00 addr=0x0000 len=3 buf=0x[ff-ff-ff]

      char: xillybus: Allow 64-bit DMA on PCIe interface

      Until now, only 32-bit DMA addressing was allowed, following a report on
      some old Intel machine that dropped 64-bit PCIe packets, even though
      pci_set_dma_mask() was successful with DMA_BIT_MASK(64).

      But then came TI's Keystone II chip (ARM Cortex A15 + DSPs), which refuses
      32-bit DMA addressing (for good reasons). So 64-bit DMA is allowed as a
      fallback option.

      serial: 8250_pci: fix mode after S3/S4 resume for F81504/508/512

      Fix RS232/485 mode incorrect setting after S3/S4 resume for F81504/508/512

      We had add RS232/485 RTS control with fecf27a373f5. But when it
      resume from S3/S4, the mode register 0x40 + 0x08 * idx + 7 will
      rewrite to 0x01 (RS232 mode).

      This patch will modify 2 sections.

      One is pci_fintek_init(), if it called when first init, it will
      write mode register with 0x01. If it called from S3/S4 resume,
      it's will get the relative port data and pass it to
      pci_fintek_rs485_config() with NULL rs485 parameter.

      The another modification is in pci_fintek_rs485_config(). It'll
      re-apply old configuration when the parameter rs485 is NULL.

      staging: unisys: visornic: Convert to using napi

      Switch the visornic over to use napi.  Currently there is a kernel
      thread that sits and waits on a wait queue to get notified of incoming
      virtual interrupts. It would be nice if we could handle frame reception
      using the standard napi processing instead.  This patch creates our napi
      instance and has the rx thread schedule it

      Given that the unisys hypervisor currently requires that queue servicing
      be done by a polling loop that wakes up every 2ms, lets instead also
      convert that to a timer, which is simpler, and allows us to remove all
      the thread starting and stopping code.

      Commit e513229b4c38 ("Drivers: hv: vmbus: prevent cpu offlining on newer

      We can bo better by using cpu_hotplug_enable/disable functions instead of
      such hard-coding.

      cpu-hotplug: export cpu_hotplug_enable/cpu_hotplug_disable

      Hyper-V module needs to disable cpu hotplug (offlining) as there is no
      support from hypervisor side to reassign already opened event channels
      to a different CPU. Currently it is been done by altering
      smp_ops.cpu_disable but it is hackish.

      cpu-hotplug: convert cpu_hotplug_disabled to a counter

      As a prerequisite to exporting cpu_hotplug_enable/cpu_hotplug_disable
      functions to modules we need to convert cpu_hotplug_disabled to a counter
      to properly support disable -> disable -> enable call sequences. E.g.
      after Hyper-V vmbus module (which is supposed to be the first user of
      exported cpu_hotplug_enable/cpu_hotplug_disable) did cpu_hotplug_disable()
      hibernate path calls disable_nonboot_cpus() and if we hit an error in
      _cpu_down() enable_nonboot_cpus() will be called on the failure path (thus
      making cpu_hotplug_disabled = 0 and leaving cpu hotplug in 'enabled'
      state). Same problem is possible if more than 1 module use
      cpu_hotplug_disable/cpu_hotplug_enable on their load/unload paths. When
      one of these modules is been unloaded it is logical to leave cpu hotplug
      in 'disabled' state.

      To support the change we need to increse cpu_hotplug_disabled counter
      in disable_nonboot_cpus() unconditionally as all users of
      disable_nonboot_cpus() are supposed to do enable_nonboot_cpus() in case
      an error was returned.

      drivers:hv: Modify hv_vmbus to search for all MMIO ranges available.

      This patch changes the logic in hv_vmbus to record all of the ranges in 
the
      VM's firmware (BIOS or UEFI) that offer regions of memory-mapped I/O 
space for
      use by paravirtual front-end drivers.  The old logic just found one range
      above 4GB and called it good.  This logic will find any ranges above 1MB.

      It would have been possible with this patch to just use existing resource
      allocation functions, rather than keep track of the entire set of Hyper-V
      related MMIO regions in VMBus.  This strategy, however, is not sufficient
      when the resource allocator needs to be aware of the constraints of a
      Hyper-V virtual machine, which is what happens in the next patch in the 
series.
      So this first patch exists to show the first steps in reworking the MMIO
      allocation paths for Hyper-V front-end drivers.

      If the device is in idle mode and is in the middle of a scan it may not
      have a chance to react to the reset and then IAP commands within required
      time interval and firmware update may fail. Let's bring the device out of
      idle mode before attempting to reset it so that the scan period is smaller
      and thus it can react to the command quicker.

      With well over 200+ users of this api, there are a mere 12 users that
      actually checked the return value of this function.  And all of them

      So stop pretending like it matters, and just return void from
      misc_deregister().  If something goes wrong in the call, you will get a
      WARNING splat in the syslog so you know how to fix up your driver.
      Other than that, there's nothing that can go wrong.

      ARM: dove: create a proper PMU driver for power domains, PMU IRQs and 
resets

      The PMU device contains an interrupt controller, power control and
      resets.  The interrupt controller is a little sub-standard in that
      there is no race free way to clear down pending interrupts, so we try
      to avoid problems by reducing the window as much as possible, and
      clearing as infrequently as possible.

      The interrupt support is implemented using an IRQ domain, and the
      parent interrupt referenced in the standard DT way.

      The power domains and reset support is closely related - there is a
      defined sequence for powering down a domain which is tightly coupled
      with asserting the reset.  Hence, it makes sense to group these two
      together, and in order to avoid any locking contention disrupting this
      sequence, we avoid the use of syscon or regmap.

      This patch adds the core PMU driver: power domains must be defined in
      the DT file in order to make use of them.  The reset controller can
      be referenced in the standard way for reset controllers.

      perf tools: Per-event time support

      This patchkit adds the ability to turn off time stamps per event.

      One usaful case for partial time is to work with per-event callgraph to
      enable "PEBS threshold > 1" (https://lkml.org/lkml/2015/5/10/196), which
      can significantly reduce the sampling overhead.

      The event samples with time stamps off will not be ordered.

      f2fs: invalidate temporary meta page

      To avoid meeting garbage data in next free node block at the end of warm
      node chain when doing recovery, we will try to zero out that invalid 
block.

      If the device is not support discard, our way for zeroing out block is:
      grabbing a temporary zeroed page in meta inode, then, issue write request
      with this page.

      But, we forget to release that temporary page, so our memory usage will
      increase without gaining any hit ratio benefit, so it's better to free it
      for saving memory.

      f2fs: fix to release inode page correctly

      In following call path, we will pass a locked and referenced ipage
      pointer to get_new_data_page:
       - init_inode_metadata
        - make_empty_dir
         - get_new_data_page

      There are two exit paths in get_new_data_page when error occurs:
      1) grab_cache_page fails, ipage will not be released;
      2) f2fs_reserve_block fails, ipage will be released in callee.

      So, it's not consistent for error handling in get_new_data_page.

      For f2fs_reserve_block, it's not very easy to change the rule
      of error handling, since it's already complicated.

      Here we deside to choose an easy way to fix this issue:
      If any error occur in get_new_data_page, we will ensure releasing
      ipage in this function.

      The same issue is in f2fs_convert_inline_dir, fix that too.

      In get_meta_page, we guarantee no failure for the returned page,
      but sometimes, IO error from device will incur returning an
      non-updated page.

      Then, we still use this page as updated one, exception could happen
      when using this kind of page.

      So in this condition, we'd better freeze fs by making fs readonly and
      and stop doing checkpoint.

      f2fs: fix to build free nids from readaheaded nat pages

      When there is no enough free nids in free nid cache, we will try to
      readahead FREE_NID_PAGES:4 nat pages into page cache of meta_inode,
      then, reading nat entries in nat page for adding free nids to free nid
      cache.

      But when traversing all nat pages we readaheaded in a circulation,
      our exit condition is not set right, one more nat page will be scanned
      without readaheading, resulting worse read performance.

      This patch fixes to read the correct number nat pages to avoid bad

      f2fs: add new interfaces for extent tree

      Add a lookup and a insertion interface for extent tree.
      The new lookup return the insert position and the prev/next
      extents closest to the offset we lookup when find no match.
      The new insertion uses above parameters to improve performance.

      There are three possible insertions after the lookup in
      f2fs_update_extent_tree, two of them insert parts of removed extent
      back to tree, since no merge happens during this process, new insertion
      skips the merge check in this scanario; the another insertion inserts a
      new extent to tree, new insertion uses prev/next extent and insert
      position to insert this extent directly, and save the time of searching
      down the tree.

      As long as tree remains unchanged between lookup and insertion, this
      would work fine. And the new lookup would be useful when add
      multi-blocks extent support for insertion interface.

      ALSA: aoa-soundbus: Switch to dev_pm_ops

      Update the aoa-soundbus framework to use dev_pm_ops rather than the
      deprecated legacy suspend and resume callbacks.

      Since there isn't anything special to do at the bus level the bus driver
      does not have to implement any callbacks. The device driver core will
      automatically pick up and execute the device's PM ops.

      As there is only a single aoa-soundbus driver implementing suspend and
      resume, update both the core and driver at the same time to avoid
      unnecessary code churn.

      perf trace: Deref sys_enter pointer args with contents from 
probe:vfs_getname

      To work like strace and dereference syscall pointer args we need to
      insert probes (or tracepoints) right after we copy those bytes from
      userspace.

      Since we're formatting the syscall args at raw_syscalls:sys_enter time,
      we need to have a formatter that just stores the position where, later,
      when we get the probe:vfs_getname, we can insert the pointer contents.

      Now, if a probe:vfs_getname with this format is in place:

       # perf probe -l
        probe:vfs_getname (on getname_flags:72@/home/git/linux/fs/namei.c with 
pathname)

      That was, in this case, put in place with:

       # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
       Added new event:
        probe:vfs_getname    (on getname_flags:72 with pathname=filename:string)

       You can now use it in all perf tools, such as:

        perf record -e probe:vfs_getname -aR sleep 1
       #

      Then 'perf trace' will notice that and do the pointer -> contents
      expansion:

       # trace -e open touch /tmp/bla
        0.165 (0.010 ms): touch/17752 open(filename: /etc/ld.so.cache, flags: 
CLOEXEC) = 3
        0.195 (0.011 ms): touch/17752 open(filename: /lib64/libc.so.6, flags: 
CLOEXEC) = 3
        0.512 (0.012 ms): touch/17752 open(filename: 
/usr/lib/locale/locale-archive, flags: CLOEXEC) = 3
        0.582 (0.012 ms): touch/17752 open(filename: /tmp/bla, flags: 
CREAT|NOCTTY|NONBLOCK|WRONLY, mode: 438) = 3
       #

      Roughly equivalent to strace's output:

       # strace -rT -e open touch /tmp/bla
        0.000000 open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3 <0.000039>
        0.000317 open("/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 <0.000102>
        0.001461 open("/usr/lib/locale/locale-archive", O_RDONLY|O_CLOEXEC) = 3 
<0.000072>
        0.000405 open("/tmp/bla", O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666) = 
3 <0.000055>
        0.000641 +++ exited with 0 +++
       #

      Now we need to either look for at all syscalls that are marked as
      pointers and have some well known names ("filename", "pathname", etc)
      and set the arg formatter to the one used for the "open" syscall in this
      patch.

      This implementation works for syscalls with just a string being copied
      from userspace, for matching syscalls with more than one string being
      copied via the same probe/trace point (vfs_getname) we need to extend
      the vfs_getname probe spec to include the pointer too, but there are
      some problems with that in 'perf probe' or the kernel kprobes code, need
      to investigate before considering supporting multiple strings per
      syscall.

      perf trace: Use a constant for the syscall formatting buffer

      We were using it as a magic number, 1024, fix that.

      Eventually we need to stop doing it per line, and do it per
      arg, traversing the args at output time, to avoid the memmove()
      calls that will be used in the next cset to replace pointers
      present at raw_syscalls:sys_enter time with its contents that
      appear at probe:vfs_getname time, before raw_syscalls:sys_exit
      time.

      ASN.1: Handle 'ANY OPTIONAL' in grammar

      An ANY object in an ASN.1 grammar that is marked OPTIONAL should be 
skipped
      if there is no more data to be had.

      This can be tested by editing X.509 certificates or PKCS#7 messages to
      remove the NULL from subobjects that look like the following:

        SEQUENCE {
          OBJECT(2a864886f70d01010b);
          NULL();
        }

      This is an algorithm identifier plus an optional parameter.

      The modified DER can be passed to one of:

        keyctl padd asymmetric "" @s </tmp/modified.x509
        keyctl padd pkcs7_test foo @s </tmp/modified.pkcs7

      It should work okay with the patch and produce EBADMSG without.

      DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD()
      that it automatically calculates the number of items in the TLV and is
      hence less prone to manual error.

      rtc: mxc: use a second rtc clock

      The mxc RTC needs two clocks, one for the input
      reference, and one for the IP. But this driver
      was only using one clock (for the reference).
      This patch add the second clock (for the IP).

      drm/vmwgfx: Implement fbdev on kms v2

      With screen targets the old legacy display system fbdev doesn't work
      satisfactory anymore. At best the resolution is severely restricted.
      Therefore implement fbdev on top of the kms system. With this change, 
fbdev
      will be using whatever KMS backend is chosen.

      There are helpers available for this, so in the future we'd probably want
      to implement the helper callbacks instead of calling into our KMS
      implementation directly.

      v2: Make sure we take the mode_config mutex around modesetting,
      Also clear the initial framebuffer using vzalloc instead of vmalloc.

      drm/vmwgfx: Add a kernel interface to create a framebuffer v2

      The kernel interface is needed for fbdev, and needs to be free from
      a file_priv member. To accomplish this, remove the fb surface mutex
      and list which isn't used anymore, anyway.

      Finally, make the pin() and unpin() pin the framebuffer for all display
      system backends, so that fbdev can pin its framebuffer before mapping it.

      v2: Address review comments:
      - Fix vmw_framebuffer_unpin() to handle also the surface framebuffer case.
      - Fix vmw_kms_new_framebuffer() to actually use the only_2d parameter.

      drm/vmwgfx: Replace SurfaceDMA usage with SurfaceCopy in 2D VMs

      This patch address the following underlying issues with SurfaceDMA

      * SurfaceDMA command does not work in a 2D VM, but we can wrap a
        proxy surface around the same DMA buffer and use the SurfaceCopy
        command which does work in a 2D VM.

      * Wrapping a DMA buffer with a proxy surface also gives us an
        added optimization path for the case when the DMA buf
        dimensions match the mode.  In this case, the DMA buf can
        be pinned as the display surface, saving an extra copy.
        This only works in a 2D VM because we won't be doing any
        rendering operations directly to the display surface.

      v2
      * Moved is_dmabuf_proxy field to vmw_framebuffer_surface
      * Undone coding style changes
      * Addressed other issues from review

      ASN.1: Fix non-match detection failure on data overrun

      If the ASN.1 decoder is asked to parse a sequence of objects, non-optional
      matches get skipped if there's no more data to be had rather than a
      data-overrun error being reported.

      This is due to the code segment that decides whether to skip optional
      matches (ie. matches that could get ignored because an element is marked
      OPTIONAL in the grammar) due to a lack of data also skips non-optional
      elements if the data pointer has reached the end of the buffer.

      This can be tested with the data decoder for the new RSA akcipher 
algorithm
      that takes three non-optional integers.  Currently, it skips the last
      integer if there is insufficient data.

      Without the fix, #defining DEBUG in asn1_decoder.c will show something
      like:

        next_op: pc=0/13 dp=0/270 C=0 J=0
        - match? 30 30 00
        - TAG: 30 266 CONS
        next_op: pc=2/13 dp=4/270 C=1 J=0
        - match? 02 02 00
        - TAG: 02 257
        - LEAF: 257
        next_op: pc=5/13 dp=265/270 C=1 J=0
        - match? 02 02 00
        - TAG: 02 3
        - LEAF: 3
        next_op: pc=8/13 dp=270/270 C=1 J=0
        next_op: pc=11/13 dp=270/270 C=1 J=0
        - end cons t=4 dp=270 l=270/270

      The next_op line for pc=8/13 should be followed by a match line.

      This is not exploitable for X.509 certificates by means of shortening the
      message and fixing up the ASN.1 CONS tags because:

       (1) The relevant records being built up are cleared before use.

       (2) If the message is shortened sufficiently to remove the public key, 
the
           ASN.1 parse of the RSA key will fail quickly due to a lack of data.

       (3) Extracted signature data is either turned into MPIs (which cope with 
a
           0 length) or is simpler integers specifying algoritms and suchlike
           (which can validly be 0); and

       (4) The AKID and SKID extensions are optional and their removal is 
handled
           without risking passing a NULL to asymmetric_key_generate_id().

       (5) If the certificate is truncated sufficiently to remove the subject,
           issuer or serialNumber then the ASN.1 decoder will fail with a 'Cons
           stack underflow' return.

      This is not exploitable for PKCS#7 messages by means of removal of 
elements
      from such a message from the tail end of a sequence:

       (1) Any shortened X.509 certs embedded in the PKCS#7 message are 
survivable
           as detailed above.

       (2) The message digest content isn't used if it shows a NULL pointer,
           similarly, the authattrs aren't used if that shows a NULL pointer.

       (3) A missing signature results in a NULL MPI - which the MPI routines 
deal
           with.

       (4) If data is NULL, it is expected that the message has detached 
content and
           that is handled appropriately.

       (5) If the serialNumber is excised, the unconditional action associated
           with it will pick up the containing SEQUENCE instead, so no NULL
           pointer will be seen here.

           If both the issuer and the serialNumber are excised, the ASN.1 decode
           will fail with an 'Unexpected tag' return.

           In either case, there's no way to get to asymmetric_key_generate_id()
           with a NULL pointer.

       (6) Other fields are decoded to simple integers.  Shortening the message
           to omit an algorithm ID field will cause checks on this to fail early
           in the verification process.


      This can also be tested by snipping objects off of the end of the ASN.1 
stream
      such that mandatory tags are removed - or even from the end of internal
      SEQUENCEs.  If any mandatory tag is missing, the error EBADMSG *should* be
      produced.  Without this patch ERANGE or ENOPKG might be produced or the 
parse
      may apparently succeed, perhaps with ENOKEY or EKEYREJECTED being produced
      later, depending on what gets snipped.

      Just snipping off the final BIT_STRING or OCTET_STRING from either sample
      should be a start since both are mandatory and neither will cause an

      ASN.1: Fix actions on CHOICE elements with IMPLICIT tags

      In an ASN.1 description where there is a CHOICE construct that contains
      elements with IMPLICIT tags that refer to constructed types, actions to be
      taken on those elements should be conditional on the corresponding element
      actually being matched.  Currently, however, such actions are performed
      unconditionally in the middle of processing the CHOICE.

      For example, look at elements 'b' and 'e' here:

        A ::= SEQUENCE {
                        CHOICE {
                        b [0] IMPLICIT B ({ do_XXXXXXXXXXXX_b }),
                        c [1] EXPLICIT C ({ do_XXXXXXXXXXXX_c }),
                        d [2] EXPLICIT B ({ do_XXXXXXXXXXXX_d }),
                        e [3] IMPLICIT C ({ do_XXXXXXXXXXXX_e }),
                        f [4] IMPLICIT INTEGER ({ do_XXXXXXXXXXXX_f })
                        }
                } ({ do_XXXXXXXXXXXX_A })

        B ::= SET OF OBJECT IDENTIFIER ({ do_XXXXXXXXXXXX_oid })

        C ::= SET OF INTEGER ({ do_XXXXXXXXXXXX_int })

      They each have an action (do_XXXXXXXXXXXX_b and do_XXXXXXXXXXXX_e) that
      should only be processed if that element is matched.

      The problem is that there's no easy place to hang the action off in the
      subclause (type B for element 'b' and type C for element 'e') because
      subclause opcode sequences can be shared.

      To fix this, introduce a conditional action opcode(ASN1_OP_MAYBE_ACT) that
      the decoder only processes if the preceding match was successful.  This 
can
      be seen in an excerpt from the output of the fixed ASN.1 compiler for the
      above ASN.1 description:

        [  13] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // e
        [  14] =  _tagn(CONT, CONS,  3),
        [  15] =  _jump_target(45),             // --> C
        [  16] =  ASN1_OP_MAYBE_ACT,
        [  17] =  _action(ACT_do_XXXXXXXXXXXX_e),

      In this, if the op at [13] is matched (ie. element 'e' above) then the
      action at [16] will be performed.  However, if the op at [13] doesn't 
match
      or is skipped because it is conditional and some previous op matched, then
      the action at [16] will be ignored.

      Note that to make this work in the decoder, the ASN1_OP_RETURN op must set
      the flag to indicate that a match happened.  This is necessary because the
      _jump_target() seen above introduces a subclause (in this case an object 
of
      type 'C') which is likely to alter the flag.  Setting the flag here is 
okay
      because to process a subclause, a match must have happened and caused a
      jump.

      This cannot be tested with the code as it stands, but rather affects 
future
      code.

      ASN.1: Fix handling of CHOICE in ASN.1 compiler

      Fix the handling of CHOICE types in the ASN.1 compiler to make SEQUENCE 
and
      SET elements in a CHOICE be correctly rendered as skippable and 
conditional
      as appropriate.

      For example, in the following ASN.1:

        Foo ::= SEQUENCE { w1 INTEGER, w2 Bar, w3 OBJECT IDENTIFIER }
        Bar ::= CHOICE {
                x1 Seq1,
                x2 [0] IMPLICIT OCTET STRING,
                x3 Seq2,
                x4 SET OF INTEGER
        }
        Seq1 ::= SEQUENCE { y1 INTEGER, y2 INTEGER, y3 INTEGER }
        Seq2 ::= SEQUENCE { z1 BOOLEAN, z2 BOOLEAN, z3 BOOLEAN }

      the output in foo.c generated by:

        ./scripts/asn1_compiler foo.asn1 foo.c foo.h

      included:

        // Bar
        // Seq1
        [   4] =  ASN1_OP_MATCH,
        [   5] =  _tag(UNIV, CONS, SEQ),
        ...
        [  13] =  ASN1_OP_COND_MATCH_OR_SKIP,           // x2
        [  14] =  _tagn(CONT, PRIM,  0),
        // Seq2
        [  15] =  ASN1_OP_MATCH,
        [  16] =  _tag(UNIV, CONS, SEQ),
        ...
        [  24] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // x4
        [  25] =  _tag(UNIV, CONS, SET),
        ...
        [  27] =  ASN1_OP_COND_FAIL,

      as a result of the CHOICE - but this is wrong on lines 4 and 15 because
      both of these should be skippable (one and only one of the four can be
      picked) and the one on line 15 should also be conditional so that it is
      ignored if anything before it matches.

      After the patch, it looks like:

        // Bar
        // Seq1
        [   4] =  ASN1_OP_MATCH_JUMP_OR_SKIP,           // x1
        [   5] =  _tag(UNIV, CONS, SEQ),
        ...
        [   7] =  ASN1_OP_COND_MATCH_OR_SKIP,           // x2
        [   8] =  _tagn(CONT, PRIM,  0),
        // Seq2
        [   9] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // x3
        [  10] =  _tag(UNIV, CONS, SEQ),
        ...
        [  12] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // x4
        [  13] =  _tag(UNIV, CONS, SET),
        ...
        [  15] =  ASN1_OP_COND_FAIL,

      where all four options are skippable and the second, third and fourth are
      all conditional, as is the backstop at the end.

      This hasn't been a problem so far because in the ASN.1 specs we have are
      either using primitives or are using SET OF and SEQUENCE OF which are
      handled correctly.

      Whilst we're at it, also make sure that element labels get included in
      comments in the output for elements that have complex types.

      This cannot be tested with the code as it stands, but rather affects 
future
      code.

      We got the bug that qemu complained with "KVM: unknown exit, hardware
      reason 31" and KVM shown these info:
      [84245.284948] EPT: Misconfiguration.

      [84245.285723] ept_misconfig_inspect_spte: spte 0x52e40dad77 level 1

      This is because we got a mmio #PF and the handler see the mmio spte 
becomes
      normal (points to the ram page)

      However, this is valid after introducing fast mmio spte invalidation which
      increases the generation-number instead of zapping mmio sptes, a example
      is as follows:
      1. QEMU drops mmio region by adding a new memslot
      2. invalidate all mmio sptes

      toshiba_acpi: Refactor *{get, set} functions return value

      This patch refactors the return value of the driver *{get, set}
      functions, since the driver default error value is -EIO.

      All the functions now check for TOS_FAILURE, TOS_NOT_SUPPORTED and
      TOS_SUCCESS.

      On TOS_FAILURE a pr_err message is printed informing the user of the
      error (no change was made to this, except the check was added to the
      functions not checking for this).

      On TOS_NOT_SUPPORTED we now return -ENODEV immediately (some
      functions were returning -EIO and some other were not checking)

      On TOS_SUCCESS* we now return 0 (as a side effect, a new success value
      was added, since some functions return one instead of zero to
      indicate success).

      As a special case, the LED functions now check for *FAILURE on
      *set, and check for TOS_FAILURE and TOS_SUCCESS on *get with their
      "default" return value set to LED_OFF.

      Also the {lcd, video}_proc* functions were adapted to reflect these
      changes to their parent HCI functions.

      This patch changes the *available functions return type from int to

      The checks for support of their respective features are done inside
      such functions and there was no need to return anything as we can
      flag the queried feature as supported inside these functions.

      The code was adapted accordingly to these changes and two new
      variables were created and another was changed from uint to bool.

      Also, the function toshiba_acceleremoter_supported was renamed to
      toshiba_accelerometer_available to maintain the naming consistency on
      the driver.

      arm64: mm: ensure patched kernel text is fetched from PoU

      The arm64 booting document requires that the bootloader has cleaned the
      kernel image to the PoC. However, when a CPU re-enters the kernel due to
      either a CPU hotplug "on" event or resuming from a low-power state (e.g.
      cpuidle), the kernel text may in-fact be dirty at the PoU due to things
      like alternative patching or even module loading.

      Thanks to I-cache speculation with the MMU off, stale instructions could
      be fetched prior to enabling the MMU, potentially leading to crashes
      when executing regions of code that have been modified at runtime.

      This patch addresses the issue by ensuring that the local I-cache is
      invalidated immediately after a CPU has enabled its MMU but before
      jumping out of the identity mapping. Any stale instructions fetched from
      the PoC will then be discarded and refetched correctly from the PoU.
      Patching kernel text executed prior to the MMU being enabled is
      prohibited, so the early entry code will always be clean.

      x86/entry/32: Remove 32-bit syscall audit optimizations

      The asm audit optimizations are ugly and obfuscate the code too
      much. Remove them.

      This will regress performance if syscall auditing is enabled on
      32-bit kernels and SYSENTER is in use. If this becomes a
      problem, interested parties are encouraged to implement the
      equivalent of the 64-bit opportunistic SYSRET optimization.

      Alternatively, a case could be made that, on 32-bit kernels, a
      less messy asm audit optimization could be done. 32-bit kernels
      don't have the complicated partial register saving tricks that
      64-bit kernels have, so the SYSENTER post-syscall path could
      just call the audit hooks directly.  Any reimplementation of
      this ought to demonstrate that it only calls the audit hook once
      per syscall, though, which does not currently appear to be true.

      Someone would have to make the case that doing so would be
      better than implementing opportunistic SYSEXIT, though.

      BPP bits defined in VBT should be used only on panels whose
      edid version is 1.3 or older. EDID version 1.4 introduced offsets
      where bpp is defined and read into display_info, hence bpp from

      drm/i915/skl: revert duplicated WaBarrierPerformanceFixDisable:skl

      With this simple git diff command one can see that skl_init_workarounds()

      This happened when the backmerge of drm-intel-fixes-2015-07-15
      Merged the same fix on both sides. Same fix but not identical enough for
      git: with a different surrounding context; hence the code duplication.

      This commit merely reverts the output of the git command above
       = the duplication introduced in the backmerge.

      It is true that in a product we won't keep disabling and enabling planes 
so
      frequently, but for safeness let's stay conservative.

      It is also true that 500ms is an etternity. But PSR is anyway a power 
saving
      feature for idle scenario. So if it is idle feature stays on and 500ms to 
get
      it reanabled is not that insane.

      v2: Rebase over intel_psr.c and fix typo.
      v3: Revival: Manual tests indicated that this is needed. With a short 
delay
          there is a huge risk of getting blank screens when planes are being 
enabled.
      v4: Revival 2 with reasonable delay. 1/2 sec instead of 5. VBT is 10 sec 
but
          actually time for link training what we aren't doing, but with only 
100 sec
          in some cases kms_psr_sink_crc manual was showing blank screen,
          so let's use this for now. Also changed comment by a FIXME.
      v5: Rebase after a long time, remove FIXME and update comment above.
      v6: msecs_to_jiffies is already on delay. remove duplication.
      v7: use msecs_to_jiffies on schedule_delayed_work call.

      This is just a preparation patch to make clear what operation we
      are performing. There is no functional change on the sink crc
      logic.

      hsw_disable_ips has been moved a bit further in the start function
      to avoid disabling ips when sink crc is not going to be started.
      and to avoid goto on this function.

      v2: explain why hsw_disable_ips() call place has changed.

      drm/i915: special-case dirtyfb for frontbuffer tracking

      First, an introduction. We currently have two types of GTT mmaps: the
      "normal" old mmap, and the WC mmap. For frontbuffer-related features
      that have automatic hardware tracking, only the non-WC mmap writes are
      detected by the hardware. Since inside the Kernel both are treated as
      ORIGIN_GTT, any features ignoring ORIGIN_GTT because of the hardware
      tracking are destined to fail.

      One of the special rules defined for the WC mmaps is that the user
      should call the dirtyfb IOCTL after he is done using the pointers, so
      that results in an intel_fb_obj_flush() call. The problem is that the
      dirtyfb is passing ORIGIN_GTT, so it is being ignored by FBC - even
      though the hardware tracking is not detecing the WC mmap operations.
      So in order to fix that without having to give up the automatic
      hardware tracking for GTT mmaps we transform the flush operation from
      dirtyfb into a special operation: ORIGIN_DIRTYFB.

      This commit fixes all the kms_frontbuffer_tracking subtests that
      contain "fbc" and "mmap-wc" in their names and are currently failing
      (for a total of 16 subtests).

      drm/i915: don't disable FBC for pipe A when flipping pipe B

      Use the appropriate call.

      I know there's a discussion about whether we need this call here at
      all, but removing the call means we'll only update FBC after we get
      the page flip IRQ. So the user may only see the new frame a little
      after it should. Let's wait just a little bit more before removing
      this call since we can rely in the HW tracking for accurate flips.

      drm/i915: don't call intel_fbc_update() at intel_unpin_work_fn()

      Because intel_unpin_work_fn() already calls
      intel_frontbuffer_flip_complete() which will call intel_fbc_flush()
      which will call intel_fbc_update() when needed.

      We couldn't fix this previously due to the fact that FBC was not
      properly behaving as intended on frontbuffer flushes, but now that
      this is fixed, we can remove the additional call.

      drm/i915: fix FBC frontbuffer tracking flushing code

      Due to the way busy_bits was handled, we were not doing any flushes if
      we didn't previously get an invalidate. Since it's possible to get
      flushes without an invalidate first, remove the busy_bits early
      return.

      So now that we don't have the busy_bits guard anymore we'll need the
      origin check for the GTT tracking (we were not doing anything on GTT
      flushes due to the GTT check at invalidate()).

      As a last detail, since we can get multiple consecutive flushes,
      disable FBC before updating it, otherwise intel_fbc_update() will just
      keep FBC enabled instead of restarting it.

      Notice that this does not fix any of the current IGT tests due to the
      fact that we still have a few intel_fbc() calls at points where we
      also have the frontbuffer tracking calls: we didn't fully convert to
      frontbuffer tracking yet. Once we remove those calls and start relying
      only on the frontbuffer tracking infrastructure we'll need this patch.

      ====================
      Netfilter updates for net-next

      The following patchset contains Netfilter updates for net-next, they are:

      1) A couple of cleanups for the netfilter core hook from Eric Biederman.

      2) Net namespace hook registration, also from Eric. This adds a 
dependency with
         the rtnl_lock. This should be fine by now but we have to keep an eye 
on this
         because if we ever get the per-subsys nfnl_lock before rtnl we have may
         problems in the future. But we have room to remove this in the future 
by
         propagating the complexity to the clients, by registering hooks for 
the init
         netns functions.

      3) Update nf_tables to use the new net namespace hook infrastructure, 
also from
         Eric.

      4) Three patches to refine and to address problems from the new net 
namespace
         hook infrastructure.

      5) Switch to alternate jumpstack in xtables iff the packet is reentering. 
This
         only applies to a very special case, the TEE target, but Eric Dumazet
         reports that this is slowing down things for everyone else. So let's 
only
         switch to the alternate jumpstack if the tee target is in used through 
a
         static key. This batch also comes with offline precalculation of the
         jumpstack based on the callchain depth. From Florian Westphal.

      6) Minimal SCTP multihoming support for our conntrack helper, from Michal
         Kubecek.

      7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from 
Florian
         Westphal.

      8) Fix several checkpatch errors in bridge netfilter, from Bernhard 
Thaler.

      9) Get rid of useless debug message in ip6t_REJECT, from Subash Abhinov.

      Drivers: hv: vmbus: prefer 'die' notification chain to 'panic'

      current_pt_regs() sometimes returns regs of the userspace process and in
      case of a kernel crash this is not what we need to report. E.g. when we
      trigger crash with sysrq we see the following:
      ...
       RIP: 0010:[<ffffffff815b8696>]  [<ffffffff815b8696>] 
sysrq_handle_crash+0x16/0x20
       RSP: 0018:ffff8800db0a7d88  EFLAGS: 00010246
       RAX: 000000000000000f RBX: ffffffff820a0660 RCX: 0000000000000000
      ...
      at the same time current_pt_regs() give us:
      ip=7f899ea7e9e0, ax=ffffffffffffffda, bx=26c81a0, cx=7f899ea7e9e0, ...
      These registers come from the userspace process triggered the crash. As we
      don't even know which process it was this information is rather useless.

      When kernel crash happens through 'die' proper regs are being passed to
      all receivers on the die_chain (and panic_notifier_list is being notified
      with the string passed to panic() only). If panic() is called manually
      (e.g. on BUG()) we won't get 'die' notification so keep the 'panic'
      notification reporter as well but guard against double reporting.

      Drivers: hv: vmbus: add special kexec handler

      When general-purpose kexec (not kdump) is being performed in Hyper-V guest
      the newly booted kernel fails with an MCE error coming from the host. It
      is the same error which was fixed in the "Drivers: hv: vmbus: Implement
      the protocol for tearing down vmbus state" commit - monitor pages remain
      special and when they're being written to (as the new kernel doesn't know
      these pages are special) bad things happen. We need to perform some
      minimalistic cleanup before booting a new kernel on kexec. To do so we
      need to register a special machine_ops.shutdown handler to be executed
      before the native_machine_shutdown(). Registering a shutdown notification
      handler via the register_reboot_notifier() call is not sufficient as it
      happens to early for our purposes. machine_ops is not being exported to
      modules (and I don't think we want to export it) so let's do this in
      mshyperv.c

      The minimalistic cleanup consists of cleaning up clockevents, synic MSRs,
      guest os id MSR, and hypercall MSR.

      Kdump doesn't require all this stuff as it lives in a separate memory
      space.

      dmaengine: Add an enum for the dmaengine alignment constraints

      Most drivers need to set constraints on the buffer alignment for async tx
      operations. However, even though it is documented, some drivers either use
      a defined constant that is not matching what the alignment variable 
expects
      (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of
      power of two.

      Add a new enum for these alignments that matches what the framework
      expects, and convert the drivers to it.

      serial: samsung: fix DMA for FIFO smaller than cache line size

      So far DMA mode were activated when only number of bytes to send was
      equal or greater than min_dma_size. Due to requirement that DMA 
transaction
      buffer should be aligned to cache line size, the excessive bytes were
      written to FIFO before starting DMA transaction. The problem occurred
      when FIFO size were smaller than cache alignment, because writing all
      excessive bytes to FIFO would fail. It happened in DMA mode when PIO
      interrupts disabled, which caused driver hung.

      The solution is to test if buffer is alligned to cache line size before
      activating DMA mode, and if it's not, running PIO mode to align buffer
      and then starting DMA transaction. In PIO mode, when interrupts are
      enabled, lack of space in FIFO isn't the problem, so buffer aligning
      will always finish with success.

      serial: Allow compile test of GPIO consumers if !GPIOLIB

      The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
      not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
      functionality only, can still be compiled if GPIOLIB is not enabled.

      Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
      appropriate.

      serial: 8250: Auto CTS control by HW if AFE enabled

      According to DesignWare 8250 spec, if auto flow control
      mode is enabled, a change in CTS does not cause an interrupt,
      so sw-assisted CTS flow control mode will not work properly.

      There reported an GPS firmware download failure issue, and we
      verified the root cause is, the default sw-assisted CTS flow
      control mode can not work properly since no interrupt when got
      CTS signal.

      This patch is to enable auto CTS mode by defaut if CRTSCTS
      is enable for DesignWare 8250 controller.

      twl4030_charger: Increase current carefully while watching voltage.

      The USB Battery Charging spec (BC1.2) suggests a dedicated
      charging port can deliver from 0.5 to 5.0A at between 4.75 and 5.25
      volts.

      To choose the "correct" current voltage setting requires a trial
      and error approach: try to draw current and see if the voltage drops
      too low.

      Even with a configured Standard Downstream Port, it may not be possible
      to reliably pull 500mA - depending on cable quality and source
      quality I have reports of charging failure due to the voltage dropping
      too low.

      To address both these concerns, this patch introduce incremental
      current setting.
      The current pull from VBUS is increased in steps of 20mA every 100ms
      until the target is reached or until the measure voltage drops below
      4.75V.  If the voltage does go too low, the target current is reduced
      by 20mA and kept there.

      This applies to currents selected automatically, or to values
      set via sysfs.  So setting a large value will cause the maximum
      available to be used - up to the limit of 1.7A imposed by the
      hardware.

      twl4030_charger: add software controlled linear charging mode.

      Add a 'continuous' option for usb charging which enables

      Linear charging does a good job with not-so-reliable power sources.
      Auto mode does not work well as it switches off when voltage drops
      momentarily.  Care must be taken not to over-charge.

      It was used with a bike hub dynamo since a year or so. In that case
      there are automatically charging stops when the cyclist needs a break.

      twl4030_charger: distinguish between USB current and 'AC' current

      The twl4030 charger has two current sources, 'USB' and 'AC'
      (presumably "Accessory Charger" because it isn't Alternating Current).

      If 'AC' is providing current, we should set the current limit
      differently to when it isn't (and so USB is used).
      So split 'cur' into 'usb_cur' and 'ac_cur' and use accordingly.

      Now we must review the current setting on any interrupt or USB
      event which might indicate that the charger-source has changed.

      dmaengine: shdma: Make dummy shdma_chan_filter() always return false

      If CONFIG_SH_DMAE_BASE (which is required for DMA engine support for
      legacy SH, SH/R-Mobile, and R-Car Gen1, but not for R-Car Gen2) is not
      enabled, but CONFIG_RCAR_DMAC (for R-Car Gen2 DMA engine support) is,
      and the DTS doesn't provide a "dmas" property for a device,
      dma_request_slave_channel_compat() incorrectly succeeds, and returns a
      DMA channel.

      However, when trying to use that DMA channel later, it fails with:

          rcar-dmac e6700000.dma-controller: rcar_dmac_prep_slave_sg: bad 
parameter: len=1, id=-22

      (Fortunately most drivers can handle this failure, and fall back to
      PIO)

      The reason for this is that a NULL legacy filter function is used, which
      actually means "all channels are OK", not "do not match".
      If CONFIG_SH_DMAE_BASE is enabled (like in shmobile_defconfig, which
      supports other SoCs besides R-Car Gen2), shdma_chan_filter() correctly
      returns false, as no available channel on R-Car Gen2 matches a
      shdma-base channel.
      If the DTS does provide a "dmas" property, dma_request_slave_channel()
      succeeds, and legacy filter-based matching is not used.

      To fix this, change shdma_chan_filter from being NULL to a dummy
      function that always returns false, like is done on other platforms.

      twl4030_charger: allow fine control of charger current.

      The twl4030 allows control of the incoming current.
      Part of this control is a 'CGAIN' setting which doubles
      the range for half the precision.  This control affects
      several different current setting, so all need to be updated
      at once when CGAIN is changed.

      With this patch, all of these current setting are managed
      by the driver, but most are left at their default settings.

      The current drawn is set to 500mA if the allow_usb module parameter is
      set, and to 100mA otherwise.
      More fine control will appear in later patches.

      twl4030_charger: use runtime_pm to keep usb phy active while charging.

      The twl4030 usb phy needs to be active while we are using
      the USB VBUS as a current source for charging.
      In particular, the usb3v1 regulator must be enabled and the
      PHY_PWR_PHYPWD bit must be set to keep the phy powered.

      commit ab37813f4093a5f59cb8e083cde277289dc72ed3
          twl4030_charger: Allow charger to control the regulator that feeds it

      gave the charger control over the regulator, but didn't resolve
      the PHY_PWR_PHYPWD issue.

      Now that both of these are controlled by runtime_pm in
      phy-twl4030-usb, we can simply take a runtime_pm reference to the USB
      phy whenever the charger wants to use it as a current source.

      So this patch reverts the above commit, and adds the necessary
      runtime_pm calls.

configuring
      the MXT device.

      It also flags to Android using INPUT_PROP_DIRECT that the device should be

      Input: atmel_mxt_ts - use deep sleep mode when stopped

      The hardcoded 0x83 CTRL setting overrides other settings in that byte,
      enabling extra reporting that may not be useful on a particular platform.

      Implement improved suspend mechanism via deep sleep. By writing zero to
      both the active and idle cycle times the maXTouch device can be put into a
      deep sleep mode, using minimal power. It is necessary to issue a calibrate
      command after the chip has spent any time in deep sleep, however a soft
      reset is unnecessary.

      Use the old method on Chromebook Pixel via platform data option.

      This patch also deals with the situation where the power configuration is
      zero on probe, which would mean that the device never wakes up to execute
      commands.

      After a config download, the T7 power configuration may have changed so it
      is necessary to re-read it.

      audit: eliminate unnecessary extra layer of watch parent references

      The audit watch parent count was imbalanced, adding an unnecessary layer 
of
      watch parent references.  Decrement the additional parent reference when a
      watch is reused, already having a reference to the parent.

      audit_find_parent() gets a reference to the parent, if the parent is
      already known.  This additional parental reference is not needed if the
      watch is subsequently found by audit_add_to_parent(), and consumed if
      the watch does not already exist, so we need to put the parent if the
      watch is found, and do nothing if this new watch is added to the parent.

      If the parent wasn't already known, it is created with a refcount of 1
      and added to the audit_watch_group, then incremented by one to be
      subsequently consumed by the newly created watch in
      audit_add_to_parent().

      The rule points to the watch, not to the parent, so the rule's refcount
      gets bumped, not the parent's.

      ARM: shmobile: sh73a0 dtsi: Add missing "gpio-ranges" to gpio node

      If a GPIO driver uses gpiochip_add_pin_range() (which is usually the
      case for GPIO/PFC combos), the GPIO hogging mechanism configured from DT
      doesn't work:

          requesting hog GPIO led1-high (chip sh73a0_pfc, offset 20) failed

      The actual error code is -517 == -EPROBE_DEFER.

      The problem is that PFC+GPIO registration is handled in multiple steps:
        1. pinctrl_register(),
        2. gpiochip_add(),
        3. gpiochip_add_pin_range().

      Configuration of the hogs is handled in gpiochip_add():

          gpiochip_add
              of_gpiochip_add
                  of_gpiochip_scan_hogs
                      gpiod_hog
                          gpiochip_request_own_desc
                              __gpiod_request

                                          pinctrl_get_device_gpio_range

      However, at this point the GPIO controller hasn't been added to
      pinctrldev_list yet, so the range can't be found, and the operation fails
      with -EPROBE_DEFER.

      To fix this, add a "gpio-ranges" property to the gpio device node, so
      the ranges are added by of_gpiochip_add_pin_range(), which is called by
      of_gpiochip_add() before the call to of_gpiochip_scan_hogs().

      f2fs: expose f2fs_write_cache_pages

      If there are gced dirty pages and normal dirty pages in the mapping
      of one inode, we might writeback them alternately with discontinuous
      block address, resulting in low performance.

      This patch introduces f2fs_write_cache_pages with codes copied from
      write_cache_pages in mm/page-writeback.c.

      In this function, we refactor flow with two steps:
      1) writeback all cold type pages.
      2) writeback all non-cold type pages.

      By using this method, f2fs will writeback dirty pages with the same
      temperature in bunch mode, it makes writeouted block being with
      more continuous address, so they can be merged as much as possible
      in f2fs bio cache, and also it will reduce the chance of submiting
      small IO from block layer.

      Test environment: 8g nokia sd card (very old sd card, but it shows
      better effect when testing with this patch, and with a 32g kingston
      sd card, I didn't see much more improvement).

      Test step:
      1. touch testfile;
      2. truncate -s 512K testfile;
      3. write all pages with odd index;
      4. trigger gc by ioctl;
      5. write all pages with even index;
      6. time fsync testfile.

      real      0m0.402s

      Previously, since 'commit 4531929e3922 ("f2fs: move grabing orphan
      pages out of protection region")' was committed, in write_orphan_inodes(),
      we will grab all meta page in a batch before we use them under spinlock,
      so that we can avoid large time delay of grabbing meta pages under
      spinlock.

      Now, 'commit d6c67a4fee86 ("f2fs: revmove spin_lock for
      write_orphan_inodes")' remove the spinlock in write_orphan_inodes,
      so there is no issue we describe above, we'd better recover to move
      the grab operation to original place for readability.

      f2fs: warm up cold page after mmaped write

      With cost-benifit method, background gc will consider old section with
      fewer valid blocks as candidate victim, these old blocks in section will
      be treated as cold data, and laterly will be moved into cold segment.

      But if the gcing page is attached by user through buffered or mmaped
      write, we should reset the page as non-cold one, because this page may
      have more opportunity for further updating.

      So fix to add clearing code for the missed 'mmap' case.

      f2fs: add new ioctl F2FS_IOC_GARBAGE_COLLECT

      When background gc is off, the only way to trigger gc is executing
      a force gc in some operations who wants to grab space in disk.

      The executing condition is limited: to execute force gc, we should
      wait for the time when there is almost no more free section for LFS
      allocation. This seems not reasonable for our user who wants to
      control triggering gc by himself.

      This patch introduces F2FS_IOC_GARBAGE_COLLECT interface for
      triggering garbage collection by using ioctl. It provides our users
      one more option to trigger gc.

      * rename __drop_largest_extent to f2fs_drop_largest_extent for exporting;
      * rename misspelled word 'untill' to 'until';
      * remove unneeded 'return' in the end of f2fs_destroy_extent_tree().

      ->write_begin.

      Otherwise, page will be non-uptodate when we try to write entire

      f2fs: enhance multithread performance

      In ->writepages, we use writepages mutex lock to serialize all block
      address allocation and page submitting pairs from different inodes.
      This method makes our delayed dirty pages of one inode being written
      continously as many as possible.

      But there is one problem that we did not submit current cached bio in
      protection region of writepages mutex lock, so there is a small chance
      that we submit the one of other thread's as below, resulting in
      splitting more bios.

      thread 1                  thread 2
      ->writepages
        lock(writepages)
        ->write_cache_pages
        unlock(writepages)
                                  lock(writepages)
                                  ->write_cache_pages
        ->f2fs_submit_merged_bio
                                    ->writepage
                                  unlock(writepages)

      This may really increase time of block layer works, and may cause
      larger IO lantency.

      This patch moves the submitting operation into region of writepages
      mutex lock to avoid bio splits when concurrently writebacking is

      f2fs: restrict multimedia filename

      When testing with fs_mark, some blocks were written out as cold
      data which were mixed with warm data, resulting in splitting more
      bios.

      This is because fs_mark will create file with random filename as
      below:

      559551ee~~~~~~~~15Z29OCC05JCKQP60JQ42MKV
      559551ee~~~~~~~~NZAZ6X8OA8LHIIP6XD0L58RM

      559551f1~~~~~~~~YQOTMAOMN5CVRFOUNI026MP4

      559551f3~~~~~~~~8Y2NRK7CEPPAA02LY936PJPG

      They are regarded as cold file since their filename are ended with
      multimedia files' extension, but this should be wrong as we only
      match the extension of filename, not the whole one.

      In this patch, we try to fix the format of multimedia filename to:
      "filename + '.' + extension", then we set cold file only its
      filename matches the format.

      So after this change, it will reduce the probability we set the
      wrong cold file, also it helps a little for fs_mark's performance
      on f2fs.

X.

      cgroup: define controller file conventions

      Traditionally, each cgroup controller implemented whatever interface
      it wanted leading to interfaces which are widely inconsistent.
      Examining the requirements of the controllers readily yield that there
      are only a few control schemes shared among all.

      Two major controllers already had to implement new interface for the
      unified hierarchy due to significant structural changes.  Let's take
      the chance to establish common conventions throughout all controllers.

      This patch defines CGROUP_WEIGHT_MIN/DFL/MAX to be used on all weight
      based control knobs and documents the conventions that controllers
      should follow on the unified hierarchy.  Except for io.weight knob,
      all existing unified hierarchy knobs are already compliant.  A
      follow-up patch will update io.weight.

      iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO

      Family 8000 products has 2 embedded processors, the first
      known as LMAC (lower MAC) and implements the functionality from
      previous products, the second one is known as UMAC (upper MAC)
      and is used mainly for driver offloads as well as new features.
      The UMAC is typically â??lessâ?? real-time than the LMAC and is used
      for higher level controls.
      The UMAC's code/data size is estimated to be in the mega-byte arena,
      taking into account the code it needs to replace in the driver and
      the set of new features.

      In order to allow the UMAC to execute code that is bigger than its code
      memory, we allow the UMAC embedded processor to page out code pages on
      DRAM.

      When the device is slave on the bus(SDIO) the driver saves the UMAC's
      image pages in blocks of 32K in the DRAM and sends the layout of the
      pages to the FW. When the FW wants load / unload pages, it creates an
      interrupt,        and the driver uploads / downloads the page to an 
address in
      the a specific address on the device's memory.

      The driver can support up to 1 MB of pages.

      Add paging mechanism for the UMAC on SDIO in order to allow the program to
      use a larger virtual space while using less physical memory on the device

      iwlwifi: pcie: New RBD allocation model

      As a preperation for multiple RX queues change the RBD
      allocation model.

      The new model includes a background allocator. The allocator is
      called by the interrupt handler when there are two released
      buffers by the queue, and the allocator starts allocating eight
      pages per request.
      When the queue has released 8 pages it tries claiming the
      request. If the pages are not ready - it keeps claiming.
      This new model should make sure that RBDs are always available
      across the multiple queues.

      The RBDs are transferred between the allocator and the queue.
      The queue moves the free RBDs upon freeing them to the allocator.
      The allocator moves them back to the queue's possession when the
      request is claimed.
      The allocator has an initial pool to make sure there are always RBDs
      available for the request completion.
      Release of the buffers at exit is done per pools - the allocator
      frees its own initial pool and the queue frees its own pool.

      Existing code refactor -
      -Queue's initial pool is the size of the queue only as the allocation
      of the new buffers no longer uses this pool.
      -Removal of replenish background work, and replenish calls in the
      interrupt handler and restock().
      -The replenish() and the rxq used_list are used only during
      initialization.
      -Moved page allocation to a new function for code reuse.

      New code -
      Allocator code - new structure and functions.
      Interrupt handler uses the allocator functions for replenishing buffers.
      Reuse of the restock() method.

      iwlwifi: mvm: Add FW paging mechanism for the UMAC on PCI

      Family 8000 products has 2 embedded processors, the first
      known as LMAC (lower MAC) and implements the functionality from
      previous products, the second one is known as UMAC (upper MAC)
      and is used mainly for driver offloads as well as new features.
      The UMAC is typically â??lessâ?? real-time than the LMAC and is used
      for higher level controls.
      The UMAC's code/data size is estimated to be in the mega-byte arena,
      taking into account the code it needs to replace in the driver and
      the set of new features.

      In order to allow the UMAC to execute code that is bigger than its code
      memory, we allow the UMAC embedded processor to page out code pages on
      DRAM.

      When the device is master on the bus(PCI) the driver saves the UMAC's
      image pages in blocks of 32K in the DRAM and sends the layout of the
      pages to the FW. The FW can load / unload the pages on its own.

      The driver can support up to 1 MB of pages.

      Add paging mechanism for the UMAC on PCI in order to allow the program
      to use a larger virtual space while using less physical memory on the
      device.

      flush_scheduled_work() from a function to an inline wrapper.

      arm64: alternatives: ensure secondary CPUs execute ISB after patching

      In order to guarantee that the patched instruction stream is visible to
      a CPU, that CPU must execute an isb instruction after any related cache
      maintenance has completed.

      The instruction patching routines in kernel/insn.c get this right for
      things like jump labels and ftrace, but the alternatives patching omits
      it entirely leaving secondary cores in a potential limbo between the old
      and the new code.

      usb: gadget: add endpoint capabilities flags

      Introduce struct usb_ep_caps which contains information about capabilities
      of usb endpoints - supported transfer types and directions. This structure
      should be filled by UDC driver for each of its endpoints, and will be
      used in epautoconf in new ep matching mechanism which will replace ugly
      guessing of endpoint capabilities basing on its name.

      usb: gadget: encapsulate endpoint claiming mechanism

      So far it was necessary for usb functions to set ep->driver_data in
      endpoint obtained from autoconfig to non-null value, to indicate that
      endpoint is claimed by function (in autoconfig it was checked if endpoint
      has set this field to non-null value, and if it has, it was assumed that
      it is claimed). It could cause bugs because if some function doesn't
      set this field autoconfig could return the same endpoint more than one
      time.

      To help to avoid such bugs this patch adds claimed flag to struct usb_ep,
      and  encapsulates endpoint claiming mechanism inside 
usb_ep_autoconfig_ss()
      and usb_ep_autoconfig_reset(), so now usb functions don't need to perform
      any additional actions to mark endpoint obtained from autoconfig as 
claimed.

      rcu: Silence lockdep false positive for expedited grace periods

      In a CONFIG_PREEMPT=y kernel, synchronize_rcu_expedited()
      acquires the ->exp_funnel_mutex in rcu_preempt_state, then invokes
      synchronize_sched_expedited, which acquires the ->exp_funnel_mutex in
      rcu_sched_state.  There can be no deadlock because rcu_preempt_state
      ->exp_funnel_mutex acquisition always precedes that of rcu_sched_state.
      But lockdep does not know that, so it gives false-positive splats.

      This commit therefore associates a separate lock_class_key structure
      with the rcu_sched_state structure's ->exp_funnel_mutex, allowing
      lockdep to see the lock ordering, avoiding the false positives.

      jbd2: limit number of reserved credits

      Currently there is no limitation on number of reserved credits we can
      ask for. If we ask for more reserved credits than 1/2 of maximum
      transaction size, or if total number of credits exceeds the maximum
      transaction size per operation (which is currently only possible with
      the former) we will spin forever in start_this_handle().

      Fix this by adding this limitation at the start of start_this_handle().

      This patch also removes the credit limitation 1/2 of maximum transaction
      size, since we really only want to limit the number of reserved credits.
      There is not much point to limit the credits if there is still space in
      the journal.

      This accidentally also fixes the online resize, where due to the
      limitation of the journal credits we're unable to grow file systems with
      1k block size and size between 16M and 32M. It has been partially fixed
      by 2c869b262a10ca99cb866d04087d75311587a30c, but not entirely.

      This patch allows the use of CMA for DMA coherent memory allocation.
      At the moment if the input parameter "is_coherent" is set to true
      the allocation is not made using the CMA, which I think is not the

      HID: wacom: Remove WACOM_QUIRK_NO_INPUT

      WACOM_QUIRK_NO_INPUT is a signal to the driver that input devices
      should not be created for a particular device. This quirk was used by
      the wireless receiver to prevent any devices from being created during
      the initial probe (defering it instead until we got a tablet connection
      event in 'wacom_wireless_work').

      This quirk is not necessary now that a device_type is associated with each
      device. Any input device allocated by 'wacom_allocate_inputs' which is
      not necessary for a particular device is freed in 'wacom_register_inputs'.
      In particular, none of the wireless receivers devices have the pen, pad,
      or touch device types set so the same effect is achieved without the need
      to be explicit.

      We now return early in wacom_retrieve_hid_descriptor for wireless devices
      (to prevent the device_type from being overridden) but since we ignore the
      HID descriptor for the wireless reciever anyway, this is not an issue.

      KVM: s390: host STP toleration for VMs

      If the host has STP enabled, the TOD of the host will be changed during
      synchronization phases. These are performed during a stop_machine() call.

      As the guest TOD is based on the host TOD, we have to make sure that:
      - no VCPU is in the SIE (implicitly guaranteed via stop_machine())
      - manual guest TOD calculations are not affected

      "Epoch" is the guest TOD clock delta to the host TOD clock. We have to
      adjust that value during the STP synchronization and make sure that code
      that accesses the epoch won't get interrupted in between (via disabling
      preemption).

      irqchip/gic: Ensure gic_cpu_if_up/down() programs correct GIC instance

      Commit 3228950621d9 ("irqchip: gic: Preserve gic V2 bypass bits in cpu
      ctrl register") added a new function, gic_cpu_if_up(), to program the
      GIC CPU_CTRL register. This function assumes that there is only one GIC
      instance present and hence always uses the chip data for the primary GIC
      controller. Although it is not common for there to be a secondary, some
      devices do support a secondary. Therefore, fix this by passing
      gic_cpu_if_up() a pointer to the appropriate chip data structure.

      Similarly, the function gic_cpu_if_down() only assumes that there is a
      single GIC instance present. Update this function so that an instance
      number is passed for the appropriate GIC and return an error code on
      failure. The vexpress TC2 (which has a single GIC) is currently the only
      user of this function and so update it accordingly. Note that because the
      TC2 only has a single GIC, the call to gic_cpu_if_down() should always
      be successful.

      irqchip/gic: Only allow the primary GIC to set the CPU map

      The gic_init_bases() function initialises an array that stores the mapping
      between the GIC and CPUs. This array is a global array that is
      unconditionally initialised on every call to gic_init_bases(). Although,
      it is not common for there to be more than one GIC instance, there are
      some devices that do support nested GIC controllers and gic_init_bases()
      can be called more than once.

      A 2nd call to gic_init_bases() will clear the previous CPU mapping and
      will only setup the mapping again for the CPU calling gic_init_bases().
      Fix this by only allowing the CPU map to be configured for the primary 
GIC.

      For secondary GICs the CPU map is not relevant because these GICs do not
      directly route the interrupts to the main CPU(s) but to other GICs or
      devices.

      s390/numa: add emulation support

      NUMA emulation (aka fake NUMA) distributes the available memory to nodes
      without using real topology information about the physical memory of the
      machine.

      Splitting the system memory into nodes replicates the memory management
      structures for each node. Particularly each node has its own "mm locks"
      and its own "kswapd" task.

      For large systems, under certain conditions, this results in improved
      system performance and/or latency based on reduced pressure on the mm
      locks and the kswapd tasks.

      NUMA emulation distributes CPUs to nodes while respecting the original
      machine topology information. This is done by trying to avoid to separate
      CPUs which reside on the same book or even on the same MC. Because the
      current Linux scheduler code requires a stable cpu to node mapping, cores
      are pinned to nodes when the first CPU thread is set online.

      This patch is based on the initial implementation from Philipp Hachtmann.

      The only way I can make this work is if ->status only has !PEBS events
      set, because if it has both set we'll take that slow path which masks
      out the !PEBS bits.

      After masking there are 3 options:

       - there is one bit set, and its @bit, we increment counts[bit].

       - there are multiple bits set, we increment error[] for each set bit,
         we do not increment counts[].

       - there are no bits set, we do nothing.

      The intent was to never increment counts[] for !PEBS events.

      Now if we start out with only a single !PEBS event set, we'll pass the
      test and increment counts[] for a !PEBS and hit the warn.

      perf/x86/intel/lbr: Limit LBR accesses to TOS in callstack mode

      In callstack mode the LBR is not a ring buffer, but a stack that grows up
      and down. This means in  this case we don't need to access all LBRs, only 
the
      ones up to TOS. Do this optimization for the normal LBR read, and the 
context
      switch save/restore code. For save/restore it can be done 
unconditionally, as
      it only runs when call stack mode is active.

      This recovers some of the cost of going to 32 LBRs on Skylake.

      perf/x86/intel: Add Intel Skylake PMU support

      Add perf core PMU support for future Intel Skylake CPU cores.

      The code is based on Haswell/Broadwell.

      There is a new cache event list, based on the updated Haswell
      event list.

      Skylake has removed most counter constraints on basic
      events, so the basic constraints table now only has a single
      entry (plus the fixed counters).

      TSX support and various other setups are all shared with Haswell.

      Skylake has 32 LBR entries. Add a new LBR init function
      to set this up. The filters are all the same as Haswell.

      It also has a new LBR format with a separate LBR_INFO_* MSR,
      but that has been already added earlier.

      perf/x86/intel: Handle new arch perfmon v4 status bits

      ArchPerfmon v4 has some new status bits in GLOBAL_STATUS.

      These need to be ignored when deciding whether a NMI
      was an NMI, to avoid eating all NMIs when they
      stay set, see:

          b292d7a10487 ("perf/x86/intel: ignore CondChgd bit to avoid false NMI 
handling")

      This patch ignores the new ASIF bit, which indicates
      that SGX interfered with the PMU, and also the new
      LBR freezing bits, which are set when the LBRs get
      frozen, plus the existing CondChange (set by JTAG
      debuggers and some buggy BIOSes)

      Add support for the new LBRv5 format used on Intel Skylake CPUs.

      extension now.

      LBR_INFO also reports a cycle count to the last branch.
      Report the cycle information using the new "cycles" branch_info
      output field.

      In addition we have to context switch and clear the new INFO
      MSRs to avoid any information leaks.

      perf: Add cycles to branch_info

      Intel Skylake supports reporting the time in cycles a branch in the LBR
      took, to give a rough indication of the basic block performance.

      Export the cycle information in the branch_info structure.
      This can be done by just reusing some currently zero padding.

      This is just the generic header change. The architecture
      still needs to fill it in.

      There's no attempt to convert to real time, as we really
      want cycles here.

      perf/x86/intel/lbr: Allow time stamp for free running PEBSv3

      With PEBSv3 the PEBS record contains a time stamp. That means we can allow
      free-running PEBS without a PMI even if the user program requested a time 
stamp.
      This avoids the need to use -T to get free running PEBS, and also avoids
      any problems with mis-identifying MMAPs later.

      Move the free_running_flags state into a variable in x86_pmu and use it.
      This only works when no explicit clock_id is set.

      perf/x86/intel: Add support for PEBSv3 profiling

      PEBSv3 is the same as the existing PEBSv2 used on Haswell,
      but it adds a new TSC field. Add support to the generic
      PEBS handler to handle the new format, and overwrite
      the perf time stamp using the new native_sched_clock_from_tsc().

      Right now the time stamp is just slightly more accurate,
      as it is nearer the actual event trigger point. With
      the PEBS threshold > 1 patchkit it will be much more accurate,
      avoid the problems with MMAP mismatches earlier.
      The accurate time stamping is only implemented for
      the default trace clock for now.

      v2: Use _skl prefix. Check for default clock_id.

      PEBSv3 has a raw TSC time stamp in its memory buffer that

      Add a native_sched_clock_from_tsc() that works the same
      as native_sched_clock(), but starts with an already given

      perf/x86/intel/pt: Add new timing packet enables

      Intel PT chapter in the new Intel Architecture SDM adds several packets
      corresponding enable bits and registers that control packet generation.
      Also, additional bits in the Intel PT CPUID leaf were added to enumerate
      presence and parameters of these new packets and features.

      The packets and enables are:

        * CYC: cycle accurate mode, provides the number of cycles elapsed since
          previous CYC packet; its presence and available threshold values are
          enumerated via CPUID;

        * MTC: mini time counter packets, used for tracking TSC time between
          full TSC packets; its presence and available resolution options are
          enumerated via CPUID;

        * PSB packet period is now configurable, available period values are
          enumerated via CPUID.

      This patch adds corresponding bit and register definitions, pmu driver
      capabilities based on CPUID enumeration, new attribute format bits for
      the new featurens and extends event configuration validation function
      to take these into account.

      perf/x86/intel/pt: Do not force sync packets on every schedule-in

      Currently, the PT driver zeroes out the status register every time before
      starting the event. However, all the writable bits are already taken care
      of in pt_handle_status() function, except the new PacketByteCnt field,
      which in new versions of PT contains the number of packet bytes written
      since the last sync (PSB) packet. Zeroing it out before enabling PT forces
      a sync packet to be written. This means that, with the existing code, a
      sync packet (PSB and PSBEND, 18 bytes in total) will be generated every
      time a PT event is scheduled in.

      To avoid these unnecessary syncs and save a WRMSR in the fast path, this
      patch changes the default behavior to not clear PacketByteCnt field, so
      that the sync packets will be generated with the period specified as
      "psb_period" attribute config field. This has little impact on the trace
      data as the other packets that are normally sent within PSB+ (between PSB
      and PSBEND) have their own generation scenarios which do not depend on the
      sync packets.

      One exception where we do need to force PSB like this when tracing starts,
      so that the decoder has a clear sync point in the trace. For this purpose
      we aready have hw::itrace_started flag, which we are currently using to
      output PERF_RECORD_ITRACE_START. This patch moves setting itrace_started
      from perf core to the pmu::start, where it should still be 0 on the very
      first run.

      The check looked wrong, although I think it was actually safe.  TASK_SIZE
      is unnecessarily small for compat tasks, and it wasn't possible to make
      a range breakpoint so large it started in user space and ended in kernel
      space.

      Nonetheless, let's fix up the check for the benefit of future
      readers.  A breakpoint is in the kernel if either end is in the
      kernel.

      perf/x86/hw_breakpoints: Disallow kernel breakpoints unless kprobe-safe

      Code on the kprobe blacklist doesn't want unexpected int3
      exceptions. It probably doesn't want unexpected debug exceptions
      either. Be safe: disallow breakpoints in nokprobes code.

      On non-CONFIG_KPROBES kernels, there is no kprobe blacklist.  In
      that case, disallow kernel breakpoints entirely.

      It will be particularly important to keep hw breakpoints out of the
      entry and NMI code once we move debug exceptions off the IST stack.

      perf/x86/intel/rapl: Add support for Knights Landing (KNL)

      Knights Landing DRAM RAPL supports PKG and DRAM RAPL domains.
      DRAM RAPL has a different fixed energy unit (2^-16J) similar to
      that of HSW.

      to be advertised later to the OS via ieee80211_register_hw.
      The driver Rx indications for TCP Checksum is integrated within the
      standard Rx status. The driver responds to those indications as follows:
      If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY.
      Otherwise, report CHECKSUM_NONE.

      iwlwifi: pcie: provide a way to stop configuration if it is forbidden

      The firmware debug infrastructure allows the user to
      provide a firmware that will toggle a few registers to
      configure the debugging capabilities.
      On certain devices, certain operations are forbidden.
      Executing a forbidden operation will cause the hardware to
      die in a way that only driver unload / load will bring it
      back to life.
      Fortunately, there is a way to know in advance if those
      operations will be accepted by the device. This is where
      the new PRPH_BLOCKBIT operation plays its role. If the bit
      X from PRPH register Y is set, then we should prevent any
      further register configuration. When that happens, drop a
      line in the kernel log since this is really an error state:
      the user won't have his device configured as he expected.
      Add operations that will be used in the future:
      INDIRECT_ASSIGN, INDIRECT_SETBIT, and INDIRECT_CLEARBIT.

      Other debugging configurations (such as destination
      configuration for the monitor) will take place in any case.

      Note that this is not possible for unicast frames, as a TDLS

      This reverts commit 088070a2f6575402d3dd82e1c5a4a8e1941805f6.

      When working in d0i3_on_idle mode, we explicitly go out
      of d0i3 on resume (so other potential commands could
      be sent).

      However, D0I3_DEFER_WAKEUP is currently cleared on
      resume complete (which happens only later on), causing
      d0i3 exit to timeout.

      Since mac80211 was modified to accept incoming frames
      once drv_resume was called, we can safely revert this
      patch, and handle the pending work on iwl_mvm_resume().

      iwlwifi: add wide firmware command infrastructure for TX

      As the firmware is slowly running out of command IDs and grouping of
      commands is desirable anyway, the firmware is extending the command
      header from 4 bytes to 8 bytes to introduce a group (in place of the
      former flags field, since that's always 0 on commands and thus can
      be easily used to distinguish between the two.

      In order to support this most easily in the driver widen the command
      command ID used in the command sending functions and encode the new
      values (group and version) in the ID. That way existing code doesn't
      have to be changed (since the higher bits are 0 automatically) and
      newer code can easily use the new ID generation function to create a
      value to use in place of just the command ID.

      With the previous patch series, no opmode continues using the

      iwlwifi: dvm: move ADD_STA response handling to sync command

      This driver currently has some very confusing ADD_STA response handling
      that runs asynchronously in the background for all of the commands, but
      is only really necessary for synchronous ones (the really asynchronous
      ones can only be done for already existing stations), and for the sync
      ones it actually waits for the RX handler to return a status code.

      Rework this to keep the debug printing in the handler, but do the code
      that's supposed to have an effect only for sync commands in the command
      sending function.

      iwlwifi: mvm: LRU-assign key offsets

      The current key offset assignment algorithm always uses the lowest
      unused key offset, which will potentially lead to issues when the
      firmware will change to take the key material for TX from the key
      table rather than from the TX command.

      In order to avoid those issues (and avoid forgetting about them)
      change the key offset allocation algorithm now to avoid reusing key
      offsets quickly.

      The new algorithm always picks as the next offset the least recently
      freed offset, i.e. the offset that has been unused for the longest
      amount of time. This is implemented by having a generation counter
      for each key offset that is incremented every time a key is deleted,
      except for the one that's deleted, which is reset to zero. Thus the
      highest counter is the key that's been unused longest.

      iwlwifi: pcie: Set scheduler to work on auto mode

      During NIC initialization shared HW is reset and this disables the

      ipv4: apply lwtunnel encap for locally-generated packets

      lwtunnel encap is applied for forwarded packets, but not for
      locally-generated packets. This is because the output function is not
      overridden in __mkroute_output, unlike it is in __mkroute_input.

      The lwtunnel state is correctly set on the rth through the call to
      rt_set_nexthop, so all that needs to be done is to override the dst
      output function to be lwtunnel_output if there is lwtunnel state
      present and it requires output redirection.

      this is required for the lwtunnel encap in order to get the lwtstate.

      This would otherwise have been set by ip_output or ip6_output so set
      skb->protocol prior to calling the lwtunnel encap
      function. Additionally set skb->dev in case it is needed further down

      It is not needed as we wait after reading GPIO mapped to
      PCI-E register - it should have no side effects.

      According to sample EEPROM datasheet (AT93Cx6), max frequency for
      worst case scenario (1.8V supply) is 250kHZ (vs. 1MHz for 5V).
      Driver generates ~50kHZ clock - margin should be big enough

      mei: define async notification hbm commands

      FW has gained new capability where a FW client can asynchronously
      notify the host that an event has occurred in its process.
      The notification doesn't provide any data and host may need to query
      further the FW client in order to get details of the event.
      Host can subscribe or unsubscribe to the event notification via
      designated HBM commands, and also the notification is carried on
      a new HBM command.
      This patch adds definitions of asynchronous notification HBM commands.

      MEI bus was designed around nfc and was hard to extend.
      Instead of the hard coded way of adding the devices on the mei bus
      we scan the whole me client list and create a device for each
      eligible me client (mei_cl_bus_rescan); currently we support
      only clients with single connection and fixed address clients.
      NFC radio name detection is run as a fixup routine

      The patch replaces handling the device list based on struct me_cl
      to device list based on me_cl_devices. The creating a connection
      is pushed from the device creation time to device enablement.

      mei: bus: don't enable events implicitly in device enable

      Do not enable events implicitly in mei_cl_enable_device, it should be
      done explicitly using mei_cl_register_event_cb so the events
      are enabled only when needed.
      The NFC drivers has been already using it that way so no need for
      further changes just remove the code from mei_cl_enable_device.

      mei: bus: fix drivers and devices names confusion

      In the mei bus layer there is use of different variables
      of driver and device types with no clear naming convention.
      There are generic struct device and struct driver,
      then mei_cl_{device, driver}, and finally mei_device which
      in this context serves as a bus device.

      The patch sets following naming convention:

      the variables of type struct device remains dev
      the variables of type struct driver remains drv
      the variables of type struct mei_cl_device are now cldev
      the variables of type struct mei_cl_driver are now cldrv
      the variables of type struct mei_device are now bus, in bus
      layer context

      mei: do not access freed cb in blocking write

      The mei_cl_write function is giving up on a write cb ownership after it
      was sent or queued. The write cb is then freed in the completion
      handler. Especially during blocking write mei_cl_write function waits
      for the completion handler and then access the freed memory to fetch the
      written size.  The quick fix is to store the buffer size prior to
      sending, the size is not altered during the flow.

      act_bpf: properly support late binding of bpf action to a classifier

      Since the introduction of the BPF action in d23b8ad8ab23 ("tc: add BPF
      based action"), late binding was not working as expected. I.e. setting
      the action part for a classifier only via 'bpf index <num>', where <num>
      is the index of an existing action, is being rejected by the kernel due
      to other missing parameters.

      It doesn't make sense to require these parameters such as BPF opcodes
      etc, as they are not going to be used anyway: in this case, they're just
      allocated/parsed and then freed again w/o doing anything meaningful.

      Instead, parse and verify the remaining parameters *after* the test on
      tcf_hash_check(), when we really know that we're dealing with creation
      of a new action or replacement of an existing one and where late binding
      is thus irrelevant.

      After patch, test case is now working:

        FOO="1,6 0 0 4294967295,"
        tc actions add action bpf bytecode "$FOO"
        tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action 
bpf index 1
        tc actions show action bpf
          action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe
          index 1 ref 2 bind 1
        tc filter show dev foo
          filter protocol all pref 49152 bpf
          filter protocol all pref 49152 bpf handle 0x1 flowid 1:1 bytecode 
'1,6 0 0 4294967295'
          action order 1: bpf bytecode '1,6 0 0 4294967295' default-action pipe
          index 1 ref 2 bind 1

      Late binding of a BPF action can be useful for preloading maps (e.g. 
before
      they hit traffic) in case of eBPF programs, or to share a single eBPF 
action
      with multiple classifiers.

      Serial: imx: add dev_pm_ops to support suspend to ram/disk

      When system goes into low power states like SUSPEND_MEM and
      HIBERNATION, the hardware IP block may be powered off to reduce
      the power consumption. This power down may cause problems on
      some imx platforms, because the hardware settings are reset to
      its power on default values which may differ from the ones when
      it power off. This patch added the dev_pm_ops and implemented
      two callbacks: suspend_noirq and resume_noirq, which will save
      the necessory hardware parameters right before power down and
      recover them before system uses the hardware.

      Because added the dev_pm_ops, the old suspend/resume callbacks
      under platform_driver will not be called any more. Changed their
      prototypes and moved those two callbacks into dev_pm_ops too.

      bridge: mdb: add/del entry on all vlans if vlan_filter is enabled and vid 
is 0

      Before this patch when a vid was not specified, the entry was added with
      vid 0 which is useless when vlan_filtering is enabled. This patch makes
      the entry to be added on all configured vlans when vlan filtering is
      enabled and respectively deleted from all, if the entry vid is 0.
      This is also closer to the way fdb works with regard to vid 0 and vlan
      filtering.

      Example:
      Setup:
      $ bridge vlan add vid 256 dev eth4
      $ bridge vlan add vid 1024 dev eth4
      $ bridge vlan add vid 64 dev eth3
      $ bridge vlan add vid 128 dev eth3
      $ bridge vlan
      port      vlan ids
      eth3       1 PVID Egress Untagged
         64
         128

      eth4       1 PVID Egress Untagged
         256
         1024
      $ echo 1 > /sys/class/net/br0/bridge/vlan_filtering

      Before:
      $ bridge mdb add dev br0 port eth3 grp 239.0.0.1
      $ bridge mdb
      dev br0 port eth3 grp 239.0.0.1 temp

      After:
      $ bridge mdb add dev br0 port eth3 grp 239.0.0.1
      $ bridge mdb
      dev br0 port eth3 grp 239.0.0.1 temp vid 1
      dev br0 port eth3 grp 239.0.0.1 temp vid 128

      virtio_net: add gro capability

      Straightforward patch to add GRO processing to virtio_net.

      napi_complete_done() usage allows more aggressive aggregation,
      opted-in by setting /sys/class/net/xxx/gro_flush_timeout

      Tested:

      Setting /sys/class/net/xxx/gro_flush_timeout to 1000 nsec,
      Rick Jones reported following results.

      One VM of each on a pair of OpenStack compute nodes with E5-2650Lv3 CPUs
      and Intel 82599ES-based NICs. So, two "before" and two "after" VMs.
      The OpenStack compute nodes were running OpenStack Kilo, with VxLAN
      encapsulation being used through OVS so no GRO coming-up the host
      stack.  The compute nodes themselves were running a 3.14-based kernel.

      Single-stream netperf, CPU utilizations and thus service demands are
      based on intra-guest reported CPU.

  commit 62f46669688bf13643b91bbc30f19da1095a5ed6
  Author: Dirk Behme <dirk.behme@xxxxxxxxxxxx>
  Date:   Mon Aug 3 13:03:09 2015 -0700

      Input: zforce - make the interrupt GPIO optional

      Add support for hardware which uses an I2C Serializer / Deserializer
      (SerDes) to communicate with the zFroce touch driver. In this case the
      SerDes will be configured as an interrupt controller and the zForce driver
      will have no access to poll the GPIO line.

      To support this, we add two dedicated new GPIOs in the device tree:
      reset-gpios and irq-gpios, with the irq-gpios being optional.

      To not break the existing device trees, the index based 'gpios' entries
      are still supported, but marked as deprecated.

      With this, if the interrupt GPIO is available, either via the old or new
      device tree style, the while loop will read and handle the packets as long
      as the GPIO indicates that the interrupt is asserted (existing, unchanged
      driver behavior).

      If the interrupt GPIO isn't available, i.e. not configured via the new
      device tree style, we are falling back to one read per ISR invocation
      (new behavior to support the SerDes).

      Note that the gpiod functions help to handle the optional GPIO:
      devm_gpiod_get_index_optional() will return NULL in case the interrupt
      GPIO isn't available. And gpiod_get_value_cansleep() does cover this, too,
      by returning 0 in this case.

      thermal: consistently use int for temperatures

      The thermal code uses int, long and unsigned long for temperatures
      in different places.

      Using an unsigned type limits the thermal framework to positive
      temperatures without need. Also several drivers currently will report
      temperatures near UINT_MAX for temperatures below 0°C. This will probably
      immediately shut the machine down due to overtemperature if started below
      0°C.

      'long' is 64bit on several architectures. This is not needed since 
INT_MAX °mC
      is above the melting point of all known materials.

      Consistently use a plain 'int' for temperatures throughout the thermal 
code and
      the drivers. This only changes the places in the drivers where the 
temperature
      is passed around as pointer, when drivers internally use another type 
this is
      not changed.

      in the protected block.

      However, rx_complete() in f_printer.c calls spinlock on printer_dev->lock
      again, which will cause system hang.

      The following steps can reproduce this hang:

      1. Build the test program from Documentation/usb/gadget_printer.txt as
         g_printer
      2. Plug in the USB device to a host(such as Ubuntu).
      3. on the USB device system run:
         #modprobe g_printer.ko
         #./g_printer -read_data

      4. Unplug the USB device from the host

         The system will hang later.

      In order to avoid this deadlock, moving the spinlock from
      printer_func_disable() into printer_reset_interface() and excluding the 
block
      of calling dwc3_gadget_ep_disable(), in which the critical resource will 
be
      protected by its spinlock in rx_complete().

      This commit will fix the system hang with the following calltrace:

      It does not make much sense to call idr_preload with the same gfp mask
      as the following idr_alloc, but this is what we do in cgroup_idr_alloc.
      This patch fixes the idr_preload usage by making cgroup_idr_alloc call
      idr_alloc w/o __GFP_WAIT. Since it is now safe to call cgroup_idr_alloc
      with GFP_KERNEL, the patch also fixes all its callers appropriately.

      ARM: migrate to common PSCI client code

      Now that the common PSCI client code has been factored out to
      drivers/firmware, and made safe for 32-bit use, move the 32-bit ARM code
      over to it. This results in a moderate reduction of duplicated lines,
      and will prevent further duplication as the PSCI client code is updated
      for PSCI 1.0 and beyond.

      The two legacy platform users of the PSCI invocation code are updated to
      account for interface changes. In both cases the power state parameter
      (which is constant) is now generated using macros, so that the
      pack/unpack logic can be killed in preparation for PSCI 1.0 power state
      changes.

      ARM: psci: boot_secondary: replace __pa with virt_to_idmap

      On some PAE systems (e.g. TI Keystone), memory is above the 32-bit
      addressable limit, and the interconnect provides an aliased view of
      parts of physical memory in the 32-bit addressable space. This alias
      is strictly for boot time usage, and is not otherwise usable because
      of coherency limitations.

      In this case, virt_to_phys(secondary_startup) would return the
      physical address of the secondary CPU boot entry point, but on such
      systems, this would be above the 4GB limit.

      A separate function, virt_to_idmap(), has been provided to return a
      usable physical address for functions in the identity mapping, and
      this must be used in preference to virt_to_phys() or __pa() to find
      the physical entry point for functions in the identity mapping range.

      For other systems, virt_to_idmap() and virt_to_phys() return identical
      physical addresses.

      Printing "IOMMU is currently not supported for PCI" for
      every PCI device probed on a DT-based system proves to be

      assignment.

      Since configuring DMA masks for PCI devices via

      regard to IOMMUs there really is nothing to warn about here;
      shut it up.

      sched/fair: Provide runnable_load_avg back to cfs_rq

      The cfs_rq's load_avg is composed of runnable_load_avg and 
blocked_load_avg.
      Before this series, sometimes the runnable_load_avg is used, and sometimes
      the load_avg is used. Completely replacing all uses of runnable_load_avg
      with load_avg may be too big a leap, i.e., the blocked_load_avg is 
concerned
      to result in overrated load. Therefore, we get runnable_load_avg back.

      The new cfs_rq's runnable_load_avg is improved to be updated with all of 
the
      runnable sched_eneities at the same time, so the one sched_entity updated 
and
      the others stale problem is solved.

      sched/fair: Rewrite runnable load and utilization average tracking

      The idea of runnable load average (let runnable time contribute to weight)
      was proposed by Paul Turner and Ben Segall, and it is still followed by
      this rewrite. This rewrite aims to solve the following issues:

      1. cfs_rq's load average (namely runnable_load_avg and blocked_load_avg) 
is
         updated at the granularity of an entity at a time, which results in the
         cfs_rq's load average is stale or partially updated: at any time, only
         one entity is up to date, all other entities are effectively lagging
         behind. This is undesirable.

         To illustrate, if we have n runnable entities in the cfs_rq, as time
         elapses, they certainly become outdated:

           t0: cfs_rq { e1_old, e2_old, ..., en_old }

         and when we update:

           t1: update e1, then we have cfs_rq { e1_new, e2_old, ..., en_old }

           t2: update e2, then we have cfs_rq { e1_old, e2_new, ..., en_old }

           ...

         We solve this by combining all runnable entities' load averages 
together
         in cfs_rq's avg, and update the cfs_rq's avg as a whole. This is based
         on the fact that if we regard the update as a function, then:

         w * update(e) = update(w * e) and

         update(e1) + update(e2) = update(e1 + e2), then

         w1 * update(e1) + w2 * update(e2) = update(w1 * e1 + w2 * e2)

         therefore, by this rewrite, we have an entirely updated cfs_rq at the
         time we update it:

           t1: update cfs_rq { e1_new, e2_new, ..., en_new }

           t2: update cfs_rq { e1_new, e2_new, ..., en_new }

           ...

      2. cfs_rq's load average is different between top rq->cfs_rq and other
         task_group's per CPU cfs_rqs in whether or not blocked_load_average
         contributes to the load.

         The basic idea behind runnable load average (the same for utilization)
         is that the blocked state is taken into account as opposed to only
         accounting for the currently runnable state. Therefore, the average
         should include both the runnable/running and blocked load averages.
         This rewrite does that.

         In addition, we also combine runnable/running and blocked averages
         of all entities into the cfs_rq's average, and update it together at
         once. This is based on the fact that:

           update(runnable) + update(blocked) = update(runnable + blocked)

         This significantly reduces the code as we don't need to separately
         maintain/update runnable/running load and blocked load.

      3. How task_group entities' share is calculated is complex and imprecise.

         We reduce the complexity in this rewrite to allow a very simple rule:
         the task_group's load_avg is aggregated from its per CPU cfs_rqs's
         load_avgs. Then group entity's weight is simply proportional to its
         own cfs_rq's load_avg / task_group's load_avg. To illustrate,

         if a task_group has { cfs_rq1, cfs_rq2, ..., cfs_rqn }, then,

         task_group_avg = cfs_rq1_avg + cfs_rq2_avg + ... + cfs_rqn_avg, then

         cfs_rqx's entity's share = cfs_rqx_avg / task_group_avg * task_group's 
share

      To sum up, this rewrite in principle is equivalent to the current one, but
      fixes the issues described above. Turns out, it significantly reduces the
      code complexity and hence increases clarity and efficiency. In addition,
      the new averages are more smooth/continuous (no spurious spikes and 
valleys)
      and updated more consistently and quickly to reflect the load dynamics.

      As a result, we have less load tracking overhead, better performance,
      and especially better power efficiency due to more balanced load.

      sched/fair: Remove rq's runnable avg

      The current rq->avg is not used at all since its merge into the kernel,
      and the code is in the scheduler's hot path, so remove it.

      cpu_stop_park() does cpu_stop_signal_done() but leaves the work on
      stopper->works. The owner of this work can free/reuse this memory
      right after that and corrupt the list, so if this CPU becomes online
      again cpu_stopper_thread() will crash.

      sched/preempt: Fix cond_resched_lock() and cond_resched_softirq()

      These functions check should_resched() before unlocking 
spinlock/bh-enable:
      preempt_count always non-zero => should_resched() always returns false.
      cond_resched_lock() worked iff spin_needbreak is set.

      This patch adds argument "preempt_offset" to should_resched().

      preempt_count offset constants for that:

        PREEMPT_DISABLE_OFFSET  - offset after preempt_disable()
        PREEMPT_LOCK_OFFSET     - offset after spin_lock()
        SOFTIRQ_DISABLE_OFFSET  - offset after local_bh_distable()
        SOFTIRQ_LOCK_OFFSET     - offset after spin_lock_bh()

      sched/fair: Beef up wake_wide()

      Josef Bacik reported that Facebook sees better performance with their
      1:N load (1 dispatch/node, N workers/node) when carrying an old patch
      to try very hard to wake to an idle CPU.  While looking at wake_wide(),
      I noticed that it doesn't pay attention to the wakeup of a many partner
      waker, returning 1 only when waking one of its many partners.

      Correct that, letting explicit domain flags override the heuristic.

      While at it, adjust task_struct bits, we don't need a 64-bit counter.

      sched: Introduce the 'trace_sched_waking' tracepoint

      Mathieu reported that since 317f394160e9 ("sched: Move the second half
      of ttwu() to the remote cpu") trace_sched_wakeup() can happen out of
      context of the waker.

      This is a problem when you want to analyse wakeup paths because it is
      now very hard to correlate the wakeup event to whoever issued the
      wakeup.

      OTOH trace_sched_wakeup() is issued at the point where we set
      p->state = TASK_RUNNING, which is right were we hand the task off to
      the scheduler, so this is an important point when looking at
      scheduling behaviour, up to here its been the wakeup path everything
      hereafter is due to scheduler policy.

      To bridge this gap, introduce a second tracepoint: trace_sched_waking.
      It is guaranteed to be called in the waker context.

      sched/cputime: Guarantee stime + utime == rtime

      While the current code guarantees monotonicity for stime and utime
      independently of one another, it does not guarantee that the sum of
      both is equal to the total time we started out with.

      This confuses things (and peoples) who look at this sum, like top, and
      will report >100% usage followed by a matching period of 0%.

      Rework the code to provide both individual monotonicity and a coherent
      sum.

      locking/static_keys: Provide a selftest

      The 'jump label' self-test is in reality testing static keys - rename 
things
      accordingly.

      Also prettify the code in various places while at it.

      locking/static_keys: Add a new static_key interface

      There are various problems and short-comings with the current
      static_key interface:

       - static_key_{true,false}() read like a branch depending on the key
         value, instead of the actual likely/unlikely branch depending on
         init value.

       - static_key_{true,false}() are, as stated above, tied to the
         static_key init values STATIC_KEY_INIT_{TRUE,FALSE}.

       - we're limited to the 2 (out of 4) possible options that compile to
         a default NOP because that's what our arch_static_branch() assembly
         emits.

      So provide a new static_key interface:

        DEFINE_STATIC_KEY_TRUE(name);
        DEFINE_STATIC_KEY_FALSE(name);

      Which define a key of different types with an initial true/false
      value.

      Then allow:

         static_branch_likely()
         static_branch_unlikely()

      to take a key of either type and emit the right instruction for the
      case.

      This means adding a second arch_static_branch_jump() assembly helper
      which emits a JMP per default.

      In order to determine the right instruction for the right state,
      encode the branch type in the LSB of jump_entry::key.

      This is the final step in removing the naming confusion that has led to
      a stream of avoidable bugs such as:

        a833581e372a ("x86, perf: Fix static_key bug in load_mm_cr4()")

      ... but it also allows new static key combinations that will give us
      performance enhancements in the subsequent patches.

      Instead of spreading the branch_default logic all over the place,
      concentrate it into the one jump_label_type() function.

      This does mean we need to actually increment/decrement the enabled
      count _before_ calling the update path, otherwise jump_label_type()
      will not see the right state.

      jump_label: Rename JUMP_LABEL_{EN,DIS}ABLE to JUMP_LABEL_{JMP,NOP}

      Since we've already stepped away from ENABLE is a JMP and DISABLE is a
      NOP with the branch_default bits, and are going to make it even worse,
      rename it to make it all clearer.

      This way we don't mix multiple levels of logic attributes, but have a
      plain 'physical' name for what the current instruction patching status
      of a jump label is.

      locking/pvqspinlock: Only kick CPU at unlock time

      For an over-committed guest with more vCPUs than physical CPUs
      available, it is possible that a vCPU may be kicked twice before
      getting the lock - once before it becomes queue head and once again
      before it gets the lock. All these CPU kicking and halting (VMEXIT)
      can be expensive and slow down system performance.

      This patch adds a new vCPU state (vcpu_hashed) which enables the code
      to delay CPU kicking until at unlock time. Once this state is set,
      the new lock holder will set _Q_SLOW_VAL and fill in the hash table
      on behalf of the halted queue head vCPU. The original vcpu_halted
      state will be used by pv_wait_node() only to differentiate other
      queue nodes from the qeue head.

      locking/qrwlock: Reduce reader/writer to reader lock transfer latency

      Currently, a reader will check first to make sure that the writer mode
      byte is cleared before incrementing the reader count. That waiting is
      not really necessary. It increases the latency in the reader/writer
      to reader transition and reduces readers performance.

      This patch eliminates that waiting. It also has the side effect
      of reducing the chance of writer lock stealing and improving the
      fairness of the lock. Using a locking microbenchmark, a 10-threads 5M
      locking loop of mostly readers (RW ratio = 10,000:1) has the following
      performance numbers in a Haswell-EX box:

      locking/pvqspinlock: Order pv_unhash() after cmpxchg() on unlock slowpath

      When we unlock in __pv_queued_spin_unlock(), a failed cmpxchg() on the 
lock
      value indicates that we need to take the slow-path and unhash the
      corresponding node blocked on the lock.

      Since a failed cmpxchg() does not provide any memory-ordering guarantees,
      it is possible that the node data could be read before the cmpxchg() on
      weakly-ordered architectures and therefore return a stale value, leading
      to hash corruption and/or a BUG().

      This patch adds an smb_rmb() following the failed cmpxchg operation, so
      that the unhashing is ordered after the lock has been checked.

      locking/Documentation: Clarify failed cmpxchg() memory ordering semantics

      A failed cmpxchg does not provide any memory ordering guarantees, a
      property that is used to optimise the cmpxchg implementations on Alpha,
      PowerPC and arm64.

      This patch updates atomic_ops.txt and memory-barriers.txt to reflect
      this.

      md/raid0: update queue parameter in a safer location.

      When a (e.g.) RAID5 array is reshaped to RAID0, the updating
      of queue parameters (e.g. max number of sectors per bio) is
      done in the wrong place.
      It should be part of ->run, but it is actually part of ->takeover.
      This means it happens before level_store() calls:

        blk_set_stacking_limits(&mddev->queue->limits);

      and so it ineffective.  This can lead to errors from underlying
      devices.

      So move all the relevant settings out of create_stripe_zones()
      and into raid0_run().

      As this can lead to a bug-on it is suitable for any -stable
      kernel which supports reshape to RAID0.  So 2.6.35 or later.
      As the bug has been present for five years there is no urgency,
      so no need to rush into -stable.

takeover")

      target: Drop iSCSI use of mutex around max_cmd_sn increment

      In a performance profile, taking a mutex in iscsit_increment_maxcmdsn()
      shows up very high.  However taking a mutex around "sess->max_cmd_sn += 1"
      seems pretty silly: we're not serializing against other contexts in
      any useful way.

      I did a quick audit and there don't appear to be any other places that
      use max_cmd_sn within the mutex more than once, so this lock can't be
      providing any useful serialization.

      ebpf: add skb->hash to offset map for usage in {cls, act}_bpf or filters

      Add skb->hash to the __sk_buff offset map, so it can be accessed from
      an eBPF program. We currently already do this for classic BPF filters,
      but not yet on eBPF, it might be useful as a demuxer in combination with
      helpers like bpf_clone_redirect(), toy example:

        __section("cls-lb") int ingress_main(struct __sk_buff *skb)
        {
          unsigned int which = 3 + (skb->hash & 7);
          /* bpf_skb_store_bytes(skb, ...); */
          /* bpf_l{3,4}_csum_replace(skb, ...); */
          bpf_clone_redirect(skb, which, 0);
          return -1;
        }

      I was thinking whether to add skb_get_hash(), but then concluded the
      raw skb->hash seems fine in this case: we can directly access the hash
      w/o extra eBPF helper function call, it's filled out by many NICs on
      ingress, and in case the entropy level would not be sufficient, people
      can still implement their own specific sw fallback hash mix anyway.

      tools: iio: fix mask for 32 bit sensor data

      When the the sensor data uses 32 bits out of 32, generic_buffer prints
      the value 0 for all data read.

      In this case, the mask is shifted 32 bits, which is beyond the size of
      an integer. This will lead to the mask always being 0. Before printing,
      the mask is applied to the raw value, thus generating a final value of 0.

      Fix the mask by shifting a 64 bit value instead of an integer.

      iio: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      Tom Herbert says:

      ====================
      ipv6: Turn on auto IPv6 flow labels by default

      BSD (MacOS) has already turned on flow labels by default and this does
      not seem to be causing any problems in the Internet. Let's go ahead
      and turn them on by default. We'll continue to monitor for any devices
      start choking on them.

      Flow labels are important since they are the desired solution for
      network devices to perform ECMP and RSS (RFC6437 and RFC6438).
      Traditionally, devices perform a 5-tuple hash on packets that
      includes port numbers. For the most part, these devices can only
      compute 5-tuple hashes for TCP and UDP. This severely limits our ability
      to get good network load balancing for other protocols (IPIP, GRE,ESP,
      etc.), and hence we are limited in using other protocols. Unfortunately,
      this method is accepted as the de facto standard to the extent that
      there are several proposals to encapsulate protocols in UDP _just_ for
      the purposes for getting ECMP to work. With hosts generating flow labels
      and devices taking them as input into ECMP (several already do), we can
      start to fix this fundamental problem.

      This patch set:
       - Changes IPV6_FLOWINFO sockopt to be opt-out of flow labels for
         connections rather than opt-in
       - Disable flow label state ranges sysctl by default
       - Enable auto flow labels sysctl by default

      v2:
        - Added functions to create an skb->hash based on flowi4 and flowi6.
          These are called in output path when creating a packet
        - Call skb_get_hash_flowi6 in ip6_make_flowlabel
        - Implement the auto_flowlabels sysctl as a mode for auto flowlabels.
          There are four modes which correspond to flow labels being enabled
          and whether socket option can be used to opt in or opt out of
          using them

      ipv6: Disable flowlabel state ranges by default

      Per RFC6437 stateful flow labels (e.g. labels set by flow label manager)
      cannot "disturb" nodes taking part in stateless flow labels. While the
      ranges only reduce the flow label entropy by one bit, it is conceivable
      that this might bias the algorithm on some routers causing a load
      imbalance. For best results on the Internet we really need the full
      20 bits.

      ipv6: Implement different admin modes for automatic flow labels

      Change the meaning of net.ipv6.auto_flowlabels to provide a mode for
      automatic flow labels generation. There are four modes:

      0: flow labels are disabled
      1: flow labels are enabled, sockets can opt-out
      2: flow labels are allowed, sockets can opt-in
      3: flow labels are enabled and enforced, no opt-out for sockets

      np->autoflowlabel is initialized according to the sysctl value.

      Add skb_get_hash_flowi6 and skb_get_hash_flowi4 which derive an sk_buff
      hash from flowi6 and flowi4 structures respectively. These functions
      can be called when creating a packet in the output path where the new

blocks

      * A skb->len error-check was enabled (removed from a "#ifdef DEBUG" 
block).
      * Several unneeded "#ifdef DEBUG" blocks were removed.
      * A dev_err() was converted to the more-appropriate netdev_err().

      staging: unisys: visornic_resume needs to mirror _serverdown_complete

      Previously we simplified the serverdown function to basically turn it
      into a dev_close(), but missed the analogous logic in visornic_resume()
      (which is essentially the "book-end" of visornic_serverdown_complete()).
      As a result, during IO partition recovery, the nic would go closed when
      the IO partition went away, but would never be opened again when the IO
      partition came back.

      This patch changes visornic_resume() to use dev_open(), so that it once
      again plays nicely with visornic_serverdown_complete().  Because
      dev_open() forces us into the visornic_open() path, other logic in
      visornic_resume() was no longer necessary, and lended to simplifying
      visornic_resume() even more.

visornic_serverdown_complete")

      staging: unisys: visornic - correctly reset flag prior to send_enbdis()

      Because devdata->enab_dis_acked is the flag used to determine whether an
      enable/disable operation to the IO partition has completed, it should
      always be cleared prior to initiating the operation.  The call added to
      visornic_enable_with_timeout() added in this patch makes the usage there
      consistent with visornic_disable_with_timeout().

      staging: unisys: visornic - prevent lock recursion after IO recovery

      In the patch which changed the serverdown logic to by synchronous, we
      were
      mistakenly holding on to devdata->priv_lock in the call to
      visornic_serverdown_complete(), which ultimately ended up recursively
      attempting to grab the same lock via the path:

          --> dev_close
              --> visornic_close()
                  --> visornic_disable_with_timeout()

      ====================
      net: GENET, SYSTEMPORT and DSA netconsole

      This patch series adds support for netconsole in the GENET, SYSTEMPORT 
and DSA
      drivers.

      A small refactoring to the DSA transmit path is required to avoid 
duplicating
      the dsa_netpoll_send_skb() into each and every tagging protocol supported.

      Testing on e.g: mv643xx_eth and/or e1000e would be much appreciated!

      Changes in v2:

      - properly disable/enable interrupts in GENET and SYSTEMPORT

      - pass the reallocated SKB back to dsa_slave_xmit() in case a tag 
protocol had to
        alter the original SKB

      net: dsa: Add netconsole support

      Add support for using DSA slave network devices with netconsole, which
      requires us to allocate and free custom netpoll instances and invoke the
      parent network device poll controller callback.

      In order for netconsole to work, we need to construct the DSA tag, but
      not queue the skb for transmission on the master network device xmit
      function.

      net: dsa: Refactor transmit path to eliminate duplication

      All tagging protocols do the same thing: increment device statistics,
      make room for the tag to be inserted, create the tag, invoke the parent
      network device transmit function.

      In order to prepare for adding netpoll support, which requires the tag
      creation, but not using the parent network device transmit function, do
      some little refactoring which eliminates duplication between the 4
      tagging protocols supported.

      We need to return a sk_buff pointer back to the caller because the tag
      specific transmit function may have to reallocate the original skb (e.g:
      tag_trailer.c) and this is the one we should be transmitting, not the
      original sk_buff we were passed.

      The policy in the net driver is to attempt MCDI commands and

      by unprivileged functions.
      The ethtool selftest contains some tests which are useful on
      an unprivileged function, such as the event queue interrupt
      tests, but other tests cannot be performed as the function
      does not have the required permissions.

      If a test returns -EPERM, act as though the test was not run

      af_mpls: fix undefined reference to ip6_route_output with CONFIG_IPV6=n

      This patch series uses ipv6_stub_impl.ipv6_dst_lookup instead of
      ip6_route_output. Follows the vxlan drivers usage of
      ipv6_stub_impl.ipv6_dst_lookup.

      There is no sk in the af_mpls context from where
      ipv6_stub_impl.ipv6_dst_lookup is used. sk appears to be needed
      to get the namespace 'net' and is optional otherwise. This patch series
      changes ipv6_stub_impl.ipv6_dst_lookup to take net argument. sk remains
      optional.

      v1 - v2: use IS_BUILTIN

      v2 - v3: Use new Kconfig option that depends on (IPV6 || IPV6=n) as
         suggested by Dave. Also uses IS_ERR as suggested by Thomas.

      v3 - v4: Include missed case of (MPLS_ROUTING=y && IPV6=m) reported by
               Dave.

      v4 - v5: Use ipv6_stub_impl.ipv6_dst_lookup as suggested by Hannes

      v5 - v6: protect against null ipv6_stub by statically declaring
         a ipv6_dst_lookup NOP func

      This patch adds net argument to ipv6_stub_impl.ipv6_dst_lookup

      namespace is different. They dont seem to be from code inspection.

      bpf: add helpers to access tunnel metadata

      Introduce helpers to let eBPF programs attached to TC manipulate tunnel 
metadata:
      bpf_skb_[gs]et_tunnel_key(skb, key, size, flags)
      skb: pointer to skb
      key: pointer to 'struct bpf_tunnel_key'
      size: size of 'struct bpf_tunnel_key'
      flags: room for future extensions

      First eBPF program that uses these helpers will allocate per_cpu
      metadata_dst structures that will be used on TX.
      On RX metadata_dst is allocated by tunnel driver.

      Typical usage for TX:
      struct bpf_tunnel_key tkey;
      ... populate tkey ...
      bpf_skb_set_tunnel_key(skb, &tkey, sizeof(tkey), 0);
      bpf_clone_redirect(skb, vxlan_dev_ifindex, 0);

      RX:
      struct bpf_tunnel_key tkey = {};
      bpf_skb_get_tunnel_key(skb, &tkey, sizeof(tkey), 0);
      ... lookup or redirect based on tkey ...

      'struct bpf_tunnel_key' will be extended in the future by adding
      elements to the end and the 'size' argument will indicate which fields
      are populated, thereby keeping backwards compatibility.
      The 'flags' argument may be used as well when the 'size' is not enough or
      to indicate completely different layout of bpf_tunnel_key.

      PM / suspend: make sync() on suspend-to-RAM build-time optional

      The Linux kernel suspend path has traditionally invoked sys_sync()
      before freezing user threads.

      But sys_sync() can be expensive, and some user-space OS's do not want
      the kernel to pay the cost of sys_sync() on every suspend -- preferring
      invoke sync() from user-space if/when they want it.

      So make sys_sync on suspend build-time optional.

      The default is unchanged.

      PM / Domains: Return -EPROBE_DEFER if we fail to init or turn-on domain

      When a device is probed, the function dev_pm_domain_attach() is called
      to see if there is a power-domain that is associated with the device and
      needs to be turned on. If dev_pm_domain_attach() does not return
      -EPROBE_DEFER then the device will be probed.

      For devices using genpd, dev_pm_domain_attach() will call
      genpd_dev_pm_attach(). If genpd_dev_pm_attach() does not find a power
      domain associated with the device then it returns an error code not
      equal to -EPROBE_DEFER to allow the device to be probed. However, if
      genpd_dev_pm_attach() does find a power-domain that is associated with
      the device, then it does not return -EPROBE_DEFER on failure and hence
      the device will still be probed. Furthermore, genpd_dev_pm_attach() does
      not check the error code returned by pm_genpd_poweron() to see if the
      power-domain was turned on successfully.

      Fix this by checking the return code from pm_genpd_poweron() and
      returning -EPROBE_DEFER from genpd_dev_pm_attach on failure, if there
      is a power-domain associated with the device.

      PM / Domains: Remove intermediate states from the power off sequence

      Genpd's ->runtime_suspend() (assigned to pm_genpd_runtime_suspend())
      doesn't immediately walk the hierarchy of ->runtime_suspend() callbacks.
      Instead, pm_genpd_runtime_suspend() calls pm_genpd_poweroff() which
      postpones that until *all* the devices in the genpd are runtime suspended.

      When pm_genpd_poweroff() discovers that the last device in the genpd is
      about to be runtime suspended, it calls __pm_genpd_save_device() for *all*
      the devices in the genpd sequentially. Furthermore,
      __pm_genpd_save_device() invokes the ->start() callback, walks the
      hierarchy of the ->runtime_suspend() callbacks and invokes the ->stop()
      callback. This causes a "thundering herd" problem.

      Let's address this issue by having pm_genpd_runtime_suspend() immediately
      walk the hierarchy of the ->runtime_suspend() callbacks, instead of
      postponing that to the power off sequence via pm_genpd_poweroff(). If the
      selected ->runtime_suspend() callback doesn't return an error code, call
      pm_genpd_poweroff() to see if it's feasible to also power off the PM
      domain.

      Adopting this change enables us to simplify parts of the code in genpd,
      for example the locking mechanism. Additionally, it gives some positive
      side effects, as described below.

      i)
      One device's ->runtime_resume() latency is no longer affected by other
      devices' latencies in a genpd.

      The complexity genpd has to support the option to abort the power off
      sequence suffers from latency issues. More precisely, a device that is
      requested to be runtime resumed, may end up waiting for
      __pm_genpd_save_device() to complete its operations for *another* device.
      That's because pm_genpd_poweroff() can't confirm an abort request while it
      waits for __pm_genpd_save_device() to return.

      As this patch removes the intermediate states in pm_genpd_poweroff() while
      powering off the PM domain, we no longer need the ability to abort that
      sequence.

      ii)
      Make pm_runtime[_status]_suspended() reliable when used with genpd.

      Until the last device in a genpd becomes idle, pm_genpd_runtime_suspend()
      will return 0 without actually walking the hierarchy of the
      ->runtime_suspend() callbacks. However, by returning 0 the runtime PM core
      considers the device as runtime_suspended, so
      pm_runtime[_status]_suspended() will return true, even though the device
      isn't (yet) runtime suspended.

      After this patch, since pm_genpd_runtime_suspend() immediately walks the
      hierarchy of the ->runtime_suspend() callbacks,
      pm_runtime[_status]_suspended() will accurately reflect the status of the
      device.

      iii)
      Enable fine-grained PM through runtime PM callbacks in drivers/subsystems.

      There are currently cases were drivers/subsystems implements runtime PM
      callbacks to deploy fine-grained PM (e.g. gate clocks, move pinctrl to
      power-save state, etc.). While using the genpd, pm_genpd_runtime_suspend()
      postpones invoking these callbacks until *all* the devices in the genpd
      are runtime suspended. In essence, one runtime resumed device prevents
      fine-grained PM for other devices within the same genpd.

      After this patch, since pm_genpd_runtime_suspend() immediately walks the
      hierarchy of the ->runtime_suspend() callbacks, fine-grained PM is enabled
      throughout all the levels of runtime PM callbacks.

      iiii)
      Enable fine-grained PM for IRQ safe devices

      Per the definition for an IRQ safe device, its runtime PM callbacks must
      be able to execute in atomic context. In the path while genpd walks the
      hierarchy of the ->runtime_suspend() callbacks for the device, it uses a
      mutex. Therefore, genpd prevents that path to be executed for IRQ safe
      devices.

      As this patch changes pm_genpd_runtime_suspend() to immediately walk the
      hierarchy of the ->runtime_suspend() callbacks and without needing to use
      a mutex, fine-grained PM is enabled throughout all the levels of runtime
      PM callbacks for IRQ safe devices.

      Unfortunately this patch also comes with a drawback, as described in the
      summary below.

      Driver's/subsystem's runtime PM callbacks may be invoked even when the
      genpd hasn't actually powered off the PM domain, potentially introducing
      unnecessary latency.

      However, in most cases, saving/restoring register contexts for devices are
      typically fast operations or can be optimized in device specific ways
      (e.g. shadow copies of register contents in memory, device-specific checks
      to see if context has been lost before restoring context, etc.).

      Still, in some cases the driver/subsystem may suffer from latency if
      runtime PM is used in a very fine-grained manner (e.g. for each IO request
      or xfer). To prevent that extra overhead, the driver/subsystem may deploy
      the runtime PM autosuspend feature.

      intel_pstate: Fix possible overflow complained by Coverity

      Coverity scanning performed on intel_pstate.c shows possible
      overflow when doing left shifting:
      val = pstate << 8;
      since pstate is of type integer, while val is of u64, left shifting
      pstate might lead to potential loss of upper bits. Say, if pstate equals
      0x4000 0000, after pstate << 8 we will get zero assigned to val.
      Although pstate will not likely be that big, this patch cast the left
      operand to u64 before performing the left shift, to avoid complaining
      from Coverity.

      cpufreq: Correct a freq check in cpufreq_set_policy()

      This check was originally added by commit 9c9a43ed2734 ("[CPUFREQ]
      return error when failing to set minfreq").It attempt to return an error
      on obviously incorrect limits when we echo xxx >.../scaling_max,min_freq
      Actually we just need check if new_policy->min > new_policy->max.
      Because at least one of max/min is copied from cpufreq_get_policy().

      For example, when we echo xxx > .../scaling_min_freq, new_policy is
      copied from policy in cpufreq_get_policy. new_policy->max is same with
      policy->max. new_policy->min is set to a new value.

      Let me explain it in deduction method, first statement in if ():
      new_policy->min > policy->max
      policy->max == new_policy->max
      ==> new_policy->min > new_policy->max

      second statement in if():
      new_policy->max < policy->min
      policy->max < policy->min
      ==>new_policy->min > new_policy->max (induction method)

      So we have proved that we only need check if new_policy->min >
      new_policy->max.

      After apply this patch, we can also modify ->min and ->max at same time
      if new freq range is very much different from current freq range. For
      example, if current freq range is 480000-960000, then we want to set
      this range to 1120000-2240000, we would fail in the past because
      new_policy->min > policy->max. As long as the cpufreq range is valid, we
      has no reason to reject the user. So correct the check to avoid such
      case.

      The recover_policy is unsed in cpufreq_online() to indicate whether
      a new policy object is created or an existing one is reinitialized.

      The "recover" part of the name is slightly confusing (it should be
      "reinitialization" rather than "recovery") and the logical not (!)
      operator is applied to it in almost all of the checks it is used in,
      so replace that variable with a new one called "new_policy" that
      will be true in the case of a new policy creation.

      spi: pxa2xx: Add support for Intel Sunrisepoint

      Major difference in LPSS SPI between Intel Sunrisepoint PCH and earlier
      platforms is an integrated DMA (iDMA) engine. iDMA is an IP that is 
private
      for each LPSS host controller (UART/SPI/I2C). Other differences are 
private
      register space offset, a few private registers that are in different
      location and FIFO thresholds.

      Intel Sunrisepoint LPSS SPI and iDMA devices are probed and registered in
      MFD layer as platform devices. Here these compound devices are detected by
      matching against known PCI IDs. This allows us to share
      pxa2xx_spi_acpi_get_pdata() for setting up the platform data instead of
      duplicating it in MFD part.

      This patch adds configuration for Intel Sunrisepoint LPSS SPI, above
      detection and DMA filter function that picks the DMA channel only from an
      associated iDMA block.

      ASoC: Export OF module alias information in missing codec drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      ARM: 8392/3: smp: Only expose /sys/.../cpuX/online if hotpluggable

      Writes to /sys/.../cpuX/online fail if we determine the platform
      doesn't support hotplug for that CPU. Furthermore, if the cpu_die
      op isn't specified the system hangs when we try to offline a CPU
      and it comes right back online unexpectedly. Let's figure this
      stuff out before we make the sysfs nodes so that the online file
      doesn't even exist if it isn't (at least sometimes) possible to
      hotplug the CPU.

      Add a new 'cpu_can_disable' op and repoint all 'cpu_disable'
      implementations at it because all implementers use the op to
      indicate if a CPU can be hotplugged or not in a static fashion.
      With PSCI we may need to add a 'cpu_disable' op so that the
      secure OS can be migrated off the CPU we're trying to hotplug.
      In this case, the 'cpu_can_disable' op will indicate that all
      CPUs are hotpluggable by returning true, but the 'cpu_disable' op
      will make a PSCI migration call and occasionally fail, denying
      the hotplug of a CPU. This shouldn't be any worse than x86 where
      we may indicate that all CPUs are hotpluggable but occasionally
      we can't offline a CPU due to check_irq_vectors_for_cpu_disable()
      failing to find a CPU to move vectors to.

      pin, even if the usb-vbus0-regulator is disabled, the leaked voltage is
      enough to make vbus-det always report 1, so we do not use vbus-det on
      this board.

      arm64: restore cpu suspend/resume functionality

      Commit 4b3dc9679cf7 ("arm64: force CONFIG_SMP=y and remove redundant 
#ifdefs")
      accidentally retained code for !CONFIG_SMP in cpu_resume function. This
      resulted in the hash index being zeroed in x7 after proper computation,
      which is then used to get the cpu context pointer while resuming.

      This patch removes the remanant code and restores back the cpu suspend/
      resume functionality.

      MAINTAINERS is updated accordingly. Files added previously without a

      ARM: perf: replace arch_find_n_match_cpu_physical_id with 
of_cpu_device_node_get

      arch_find_n_match_cpu_physical_id parses the device tree to get the
      device node for a given logical cpu index. However, since ARM PMUs get
      probed after the CPU device nodes are stashed while registering the
      cpus, we can use of_cpu_device_node_get to avoid another DT parse.

      This patch replaces arch_find_n_match_cpu_physical_id with
      of_cpu_device_node_get to reuse the stashed value directly instead.

      ARM: perf: extend interrupt-affinity property for PPIs

      On systems containing multiple, heterogeneous clusters we need a way to
      associate a PMU "device" with the CPU(s) on which it exists. For PMUs
      that signal overflow with SPIs, this relationship is determined via the
      "interrupt-affinity" property, which contains a list of phandles to CPU
      nodes for the PMU. For PMUs using PPIs, the per-cpu nature of the
      interrupt isn't enough to determine the set of CPUs which actually
      contain the device.

      This patch allows the interrupt-affinity property to be specified on a
      PMU node irrespective of the interrupt type. For PPIs, it identifies
      the set of CPUs signalling the PPI in question.

      arm: perf: Set affinity for PPI based PMUs

      For PPI based PMUs, we bail out early in of_pmu_irq_cfg() without
      setting the PMU's supported_cpus bitmap. This causes the
      smp_call_function_any() in armv7_probe_num_events() to fail. Set
      the bitmap to be all CPUs so that we properly probe PMUs that use
      PPIs.

      usb: gadget: mass_storage: Fix freeing luns sysfs implementation

      Use device_is_registered() instad of sysfs flag to determine if
      we should free sysfs representation of particular LUN.

      sysfs flag in fsg common determines if luns attributes should be
      exposed using sysfs. This flag is used when creating and freeing
      luns. Unfortunately there is no guarantee that this flag will not
      be changed between creation and removal of particular LUN. Especially
      because of lun.0 which is created during allocating instance of
      function. This may lead to resource leak or NULL pointer dereference:

      x86/vm86: Use the normal pt_regs area for vm86

      Change to use the normal pt_regs area to enter and exit vm86
      mode.  This is done by increasing the padding at the top of the
      stack to make room for the extra vm86 segment slots in the IRET
      frame.  It then saves the 32-bit regs in the off-stack vm86
      data, and copies in the vm86 regs.  Exiting back to 32-bit mode
      does the reverse.  This allows removing the hacks to jump
      directly into the exit asm code due to having to change the
      stack pointer.  Returning normally from the vm86 syscall and the
      exception handlers allows things like ptrace and auditing to work 
properly.

      iommu/arm-smmu: Sort out coherency

      Currently, we detect whether the SMMU has coherent page table walk
      capability from the IDR0.CTTW field, and base our cache maintenance
      decisions on that. In preparation for fixing the bogus DMA API usage,
      however, we need to ensure that the DMA API agrees about this, which
      necessitates deferring to the dma-coherent property in the device tree
      for the final say.

      As an added bonus, since systems exist where an external CTTW signal
      has been tied off incorrectly at integration, allowing DT to override
      it offers a neat workaround for coherency issues with such SMMUs.

      USB: io_ti: Add heartbeat to keep idle EP/416 ports from disconnecting

      When using Edgeport/416 models with newer firmware (sometime after
      firmware version 4.80.0), idle ports are automatically bounced
      (disconnected and then reconnected) approximately every 60 seconds.
      This breaks programs (e.g: minicom) where idle periods are common,
      normal and expected.

      I confirmed with the manufacturer (Digi International) that Edgeport/416
      models now ship from the factory with firmware that expects periodic
      "heartbeat" queries from the driver to keep idle ports alive.  This
      patch implements heartbeat support using the mechanism Digi suggested
      (periodically requesting an I2C descriptor address) that appears effective
      on Edgeports running the newer firmware (that require it) and benign on
      Edgeport devices running older firmware.  Since we know that Edgeport
      firmware version 4.80 (the version distributed in /lib/firmware/down3.bin
      and used for Edgeports that are either running still older versions or
      have no onboard non-volatile firmware image) does not require heartbeat
      support, this patch schedules heartbeats only on Edgeport/416 devices,
      and only if they are running firmware versions newer than 4.80.

      USB: io_ti: Add firmware image sanity checks

      Do what we can to verify that the driver's firmware image is valid
      (before attempting to download it to the Edgeport) by adding a new
      function, check_fw_sanity(), and a call to it in in download_fw().

      Note: It looks like some Edgeports (models like the EP/416 with on-board
      E2PROM) may be able to function even if the on-disk firmware image is
      bad or missing, iff their local E2PROM versions are valid.  But most
      Edgeport models (I've tried EP/1 and EP/8) do not appear to have this
      capability and they always rely on the on-disk firmware image.

      I tested an implementation that calls the new check_fw_sanity()
      function at the top of download_fw() and, rather than simply returning
      an error if the firmware image is bad or missing, it saves the result
      and defers the decision until later when it may find that it is running
      on a E2PROM-equipped device with a valid image.  But I think this is
      messier than it is worth (adding still more messiness to the already
      very messy download_fw()) for such a marginal possible benefit.  So, at
      least for now, I have chosen the much simpler approach of returning an
      error whenever edge_startup() fails to load an on-disk firmware image, or
      check_fw_sanity() indicates that it is unusable.

      USB: io_ti: Fix firmware version handling

      The io_ti driver fails to download firmware to Edgeport
      devices such as the EP/416, even when the on-disk firmware image
      (/lib/firmware/edgeport/down3.bin) is more current than the version
      on the EP/416.  The current download code is broken in a few ways.
      Notably it mis-uses global variables OperationalMajorVersion and
      OperationalMinorVersion (reading their values before they've been
      properly initialized and subsequently initializing them multiple times
      without synchronization).  This patch drops the global variables and
      replaces the redundant calls to request_firmware()/release_firmware()
      in download_fw() with a single call pair in edge_startup(); the firmware
      image pointer is then passed to download_fw() and build_i2c_fw_hdr().

      Change xol_add_vma() to use _install_special_mapping(), this way
      we can name the vma installed by uprobes. Currently it looks
      like private anonymous mapping, this is confusing and
      complicates the debugging. With this change /proc/$pid/maps
      reports "[uprobes]".

      As a side effect this will cause core dumps to include the XOL vma
      and I think this is good; this can help to debug the problem if
      the app crashed because it was probed.

      install_special_mapping(pages) expects that "pages" is the zero-
      terminated array while xol_add_vma() passes &area->page, this
      means that special_mapping_fault() can wrongly use the next

      Fortunately, this area is not expandable so pgoff != 0 isn't
      possible (modulo bugs in special_mapping_vmops), but still this
      does not look good.

      uprobes/x86: Make arch_uretprobe_is_alive(RP_CHECK_CALL) more clever

      The previous change documents that cleanup_return_instances()
      can't always detect the dead frames, the stack can grow. But
      there is one special case which imho worth fixing:
      arch_uretprobe_is_alive() can return true when the stack didn't
      actually grow, but the next "call" insn uses the already
      invalidated frame.

      Test-case:

        #include <stdio.h>
        #include <setjmp.h>

        jmp_buf jmp;
        int nr = 1024;

        void func_2(void)
        {
                if (--nr == 0)
                        return;
                longjmp(jmp, 1);
        }

        void func_1(void)
        {
                setjmp(jmp);
                func_2();
        }

        int main(void)
        {
                func_1();
                return 0;
        }

      If you ret-probe func_1() and func_2() prepare_uretprobe() hits
      the MAX_URETPROBE_DEPTH limit and "return" from func_2() is not
      reported.

      When we know that the new call is not chained, we can do the
      more strict check. In this case "sp" points to the new ret-addr,
      so every frame which uses the same "sp" must be dead. The only
      complication is that arch_uretprobe_is_alive() needs to know was
      it chained or not, so we add the new RP_CHECK_CHAIN_CALL enum
      and change prepare_uretprobe() to pass RP_CHECK_CALL only if
      !chained.

      Note: arch_uretprobe_is_alive() could also re-read *sp and check
      if this word is still trampoline_vaddr. This could obviously
      improve the logic, but I would like to avoid another
      copy_from_user() especially in the case when we can't avoid the
      false "alive == T" positives.

      was called and use different checks depending on the context.
      Add the new argument to distinguish 2 callers.

      Change prepare_uretprobe() to flush the !arch_uretprobe_is_alive()
      return_instance's. This is not needed correctness-wise, but can help
      to avoid the failure caused by MAX_URETPROBE_DEPTH.

      Note: in this case arch_uretprobe_is_alive() can be false
      positive, the stack can grow after longjmp(). Unfortunately, the
      kernel can't 100% solve this problem, but see the next patch.

      uprobes: Change handle_trampoline() to flush the frames invalidated by 
longjmp()

      Test-case:

        #include <stdio.h>
        #include <setjmp.h>

        jmp_buf jmp;

        void func_2(void)
        {
                longjmp(jmp, 1);
        }

        void func_1(void)
        {
                if (setjmp(jmp))
                        return;
                func_2();
                printf("ERR!! I am running on the caller's stack\n");
        }

        int main(void)
        {
                func_1();
                return 0;
        }

      fails if you probe func_1() and func_2() because
      handle_trampoline() assumes that the probed function should must
      return and hit the bp installed be prepare_uretprobe(). But in
      this case func_2() does not return, so when func_1() returns the
      kernel uses the no longer valid return_instance of func_2().

      Change handle_trampoline() to unwind ->return_instances until we
      know that the next chain is alive or NULL, this ensures that the
      current chain is the last we need to report and free.

      Alternatively, every return_instance could use unique
      trampoline_vaddr, in this case we could use it as a key. And
      this could solve the problem with sigaltstack() automatically.

      But this approach needs more changes, and it puts the "hard"
      limit on MAX_URETPROBE_DEPTH. Plus it can not solve another
      problem partially fixed by the next patch.

      Note: this change has no effect on !x86, the arch-agnostic
      version of arch_uretprobe_is_alive() just returns "true".

      TODO: as documented by the previous change, arch_uretprobe_is_alive()
            can be fooled by sigaltstack/etc.

      uprobes/x86: Reimplement arch_uretprobe_is_alive()

      Add the x86 specific version of arch_uretprobe_is_alive()
      helper. It returns true if the stack frame mangled by
      prepare_uretprobe() is still on stack. So if it returns false,
      we know that the probed function has already returned.

      We add the new return_instance->stack member and change the
      generic code to initialize it in prepare_uretprobe, but it
      should be equally useful for other architectures.

      TODO: this assumes that the probed application can't use
            multiple stacks (say sigaltstack). We will try to improve
            this logic later.

      uprobes: Change handle_trampoline() to find the next chain beforehand

      No functional changes, preparation.

      Add the new helper, find_next_ret_chain(), which finds the first
      !chained entry and returns its ->next. Yes, it is suboptimal. We
      probably want to turn ->chained into ->start_of_this_chain
      pointer and avoid another loop. But this needs the boring
      changes in dup_utask(), so lets do this later.

      Change the main loop in handle_trampoline() to unwind the stack
      until ri is equal to the pointer returned by this new helper.

      uprobes: Send SIGILL if handle_trampoline() fails

      1. It doesn't make sense to continue if handle_trampoline()
         fails, change handle_swbp() to always return after this call.

      2. Turn pr_warn() into uprobe_warn(), and change
         handle_trampoline() to send SIGILL on failure. It is pointless to
         return to user mode with the corrupted instruction_pointer() which
         we can't restore.

        - Simplify jiffies <-> usecs conversions. Remove dead code.

        - Remove early hacks on nohz full code that avoided messing up idle
          nohz internals. Now nohz integrates well full and idle and such hack
          have become needless.

        - Restart nohz full tick from irq exit. A simplification and a

      ARM: zynq: reserve space for jump target in secondary trampoline

      Add a zero argument to the .word directive in
      zynq_secondary_trampoline.  Without an expression the assembler emits
      nothing for the .word directive.

      This makes it so that the intended range is communicated to ioremap
      and outer_flush_range in zynq_cpun_start; e.g. for LE
      trampoline_code_size evaluates to 12 now instead of 8.

      Found by inspection.  I'm not aware of any real problem this fixes.

      HID: sony: Fix DS4 controller reporting rate issues

      This commit removes the cap on the DualShock 4 controller reporting rate 
when
      connected using Bluetooth. The previous value of '0xB0' capped the rate 
to only
      20.83 Hz which many userspace utilities mistook as a sign of a bad signal.
      Since a 'B' and an '8' can look similar it's possible that someone 
mistook the
      one for another.  The new value of '0x80' enables the full 1000 Hz peak
      reporting rate that the controller is capable of.

      Frank adds: "Back when the original code was written the purpose of that 
value
      was unknown and 0xB0 seemed to work so that's what ended up being used.  
Now
      that we know what it actually does and that 0x80 is a better choice I 
support
      this patch."

      The encap shared descriptor was changed to use the new IV convention.
      In the process some commands were shifted, making the output length
      zero, caam effectively writing garbage in dst.

      While here, update the decap descriptor to execute the "write" commands
      before the "read"s (as it previously was).
      This makes sure the input fifo is drained before becoming full.

      Make the warning about unsupported SCSI opcode more useful:

       - Add in the initiator name so we know who's sending it.
       - Print the warning even for opcodes that spc_parse_cdb() knows about
         but that we don't handle.

      target/iscsi: Use proper SGL accessors for digest computation

      Current implementation assumes that all the buffers of an IO are linked
      with a single SG list, which is OK because target-core is only allocating
      a contigious scatterlist region.  However, this assumption is wrong for
      se_cmd descriptors that want to use chaining across multiple SGL regions.

      Fix this up by using proper SGL accessors for digest payload computation.

      tipc: use temporary, non-protected skb queue for bundle reception

      Currently, when we extract small messages from a message bundle, or
      when many messages have accumulated in the link arrival queue, those
      messages are added one by one to the lock protected link input queue.
      This may increase contention with the reader of that queue, in
      the function tipc_sk_rcv().

      This commit introduces a temporary, unprotected input queue in
      tipc_link_rcv() for such cases. Only when the arrival queue has been
      emptied, and the function is ready to return, does it splice the whole
      temporary queue into the real input queue.

      tipc: remove implicit message delivery in node_unlock()

      After the most recent changes, all access calls to a link which
      may entail addition of messages to the link's input queue are
      postpended by an explicit call to tipc_sk_rcv(), using a reference
      to the correct queue.

      This means that the potentially hazardous implicit delivery, using
      tipc_node_unlock() in combination with a binary flag and a cached
      queue pointer, now has become redundant.

      This commit removes this implicit delivery mechanism both for regular
      data messages and for binding table update messages.

      tipc: make resetting of links non-atomic

      In order to facilitate future improvements to the locking structure, we
      want to make resetting and establishing of links non-atomic. I.e., the
      functions tipc_node_link_up() and tipc_node_link_down() should be called
      from outside the node lock context, and grab/release the node lock
      themselves. This requires that we can freeze the link state from the
      moment it is set to RESETTING or PEER_RESET in one lock context until
      it is set to RESET or ESTABLISHING in a later context. The recently
      introduced link FSM makes this possible, so we are now ready to introduce
      the above change.

      This commit implements this.

      tipc: merge link->exec_mode and link->state into one FSM

      Until now, we have been handling link failover and synchronization
      by using an additional link state variable, "exec_mode". This variable
      is not independent of the link FSM state, something causing a risk of
      inconsistencies, apart from the fact that it clutters the code.

      The conditions are now in place to define a new link FSM that covers
      all existing use cases, including failover and synchronization, and
      eliminate the "exec_mode" field altogether. The FSM must also support
      non-atomic resetting of links, which will be introduced later.

      The new link FSM is shown below, with 7 states and 8 events.
      Only events leading to state change are shown as edges.

      tipc: move protocol message sending away from link FSM

      The implementation of the link FSM currently takes decisions about and
      sends out link protocol messages. This is unnecessary, since such
      actions are not the result of any link state change, and are even
      decided based on non-FSM state information ("silent_intv_cnt").

      We now move the sending of unicast link protocol messages to the
      function tipc_link_timeout(), and the initial broadcast synchronization
      message to tipc_node_link_up(). The latter is done because a link
      instance should not need to know whether it is the first or second
      link to a destination. Such information is now restricted to and
      handled by the link aggregation layer in node.c

      tipc: move link synch and failover to link aggregation level

      Link failover and synchronization have until now been handled by the
      links themselves, forcing them to have knowledge about and to access
      parallel links in order to make the two algorithms work correctly.

      In this commit, we move the control part of this functionality to the
      link aggregation level in node.c, which is the right location for this.
      As a result, the two algorithms become easier to follow, and the link
      implementation becomes simpler.

      tipc: reverse call order for link_reset()->node_link_down()

      In many cases the call order when a link is reset goes as follows:
      tipc_node_xx()->tipc_link_reset()->tipc_node_link_down()

      This is not the right order if we want the node to be in control,
      so in this commit we change the order to:
      tipc_node_xx()->tipc_node_link_down()->tipc_link_reset()

      The fact that tipc_link_reset() now is called from only one
      location with a well-defined state will also facilitate later
      simplifications of tipc_link_reset() and the link FSM.

      tipc: move all link_reset() calls to link aggregation level

      In line with our effort to let the node level have full control over
      its links, we want to move all link reset calls from link.c to node.c.
      Some of the calls can be moved by simply moving the calling function,
      when this is the right thing to do. For the remaining calls we use
      the now established technique of returning a TIPC_LINK_DOWN_EVT
      flag from tipc_link_rcv(), whereafter we perform the reset call when
      the call returns.

      This change serves as a preparation for the coming commits.

      tipc: eliminate function tipc_link_activate()

      The function tipc_link_activate() is redundant, since it mostly performs
      settings that have already been done in a preceding tipc_link_reset().

      There are three exceptions to this:
      - The actual state change to TIPC_LINK_WORKING. This should anyway be done
        in the FSM, and not in a separate function.
      - Registration of the link with the bearer. This should be done by the
        node, since we don't want the link to have any knowledge about its
        specific bearer.
      - Call to tipc_node_link_up() for user access registration. With the new
        role distribution between link aggregation and link level this becomes
        the wrong call order; tipc_node_link_up() should instead be called
        directly as a result of a TIPC_LINK_UP event, hence by the node itself.

      This commit implements those changes.

      net/ipv6: add sysctl option accept_ra_min_hop_limit

      Commit 6fd99094de2b ("ipv6: Don't reduce hop limit for an interface")
      disabled accept hop limit from RA if it is smaller than the current hop
      limit for security stuff. But this behavior kind of break the RFC 
definition.

      RFC 4861, 6.3.4.  Processing Received Router Advertisements
         A Router Advertisement field (e.g., Cur Hop Limit, Reachable Time,
         and Retrans Timer) may contain a value denoting that it is
         unspecified.  In such cases, the parameter should be ignored and the
         host should continue using whatever value it is already using.

         If the received Cur Hop Limit value is non-zero, the host SHOULD set
         its CurHopLimit variable to the received value.

      So add sysctl option accept_ra_min_hop_limit to let user choose the 
minimum
      hop limit value they can accept from RA. And set default to 1 to meet RFC
      standards.

      PCI: Protect pci_bus->slots with pci_slot_mutex, not pci_bus_sem

      Rajat Jain reported a deadlock when PCIe hot-add and AER recovery happen 
at
      the same time:

      thread 1:

                        pci_create_slot
                          down_write(pci_bus_sem)        # deadlock here

      thread 2:

        aer_isr_one_error
          aer_process_err_device
            do_recovery
              broadcast_error_message(..., report_error_detected)

                  down_read(&pci_bus_sem)                # acquire pci_bus_sem
                  report_error_detected(dev)             # cb()
                    device_lock(dev)                     # deadlock here

      Previously, the bus->devices and bus->slots list were protected by
      pci_bus_sem.  In pci_create_slot(), we held it for writing so we could
      add to the bus->slots list.

      Add a new local pci_slot_mutex to protect bus->slots.  Hold pci_bus_sem 
for
      reading while searching the bus->devices list.

      iSCSI: let session recovery_tmo sysfs writes persist across recovery

      The iSCSI session recovery_tmo setting is writeable in sysfs, but it's
      also set every time a connection is established when parameters are set
      from iscsid over netlink.  That results in the timeout being reset to
      the default value after every recovery.

      The DM multipath tools want to use the sysfs interface to lower the
      default timeout when there are multiple paths to fail over.  It has
      caused confusion that we have a writeable sysfs value that seem to keep
      resetting itself.

      This patch adds an in-kernel flag that gets set once a sysfs write
      occurs, and then ignores netlink parameter setting once it's been
      modified via the sysfs interface.  My thinking here is that the sysfs
      interface is much simpler for external tools to influence the session
      timeout, but if we're going to allow it to be modified directly we
      should ensure that setting is maintained.

      PCI/MSI: Free legacy IRQ when enabling MSI/MSI-X

      Once MSI/MSI-X is enabled by the device driver, a PCI device won't use
      legacy IRQs again until MSI/MSI-X is disabled.

      Call pcibios_free_irq() when enabling MSI/MSI-X and pcibios_alloc_irq()
      when disabling MSI/MSI-X.  This allows arch code to manage resources
      associated with the legacy IRQ.

      ARM64: PCI: do not enable resources on PROBE_ONLY systems

      On ARM64 PROBE_ONLY PCI systems resources are not currently claimed,
      therefore they can't be enabled since they do not have a valid
      parent pointer; this in turn prevents enabling PCI devices on
      ARM64 PROBE_ONLY systems, causing PCI devices initialization to
      fail.

      To solve this issue, resources must be claimed when devices are
      added on PROBE_ONLY systems, which ensures that the resource hierarchy
      is validated and the resource tree is sane, but this requires changes
      in the ARM64 resource management that can affect adversely existing
      PCI set-ups (claiming resources on !PROBE_ONLY systems might break
      existing ARM64 PCI platform implementations).

      As a temporary solution in preparation for a proper resources claiming
      implementation in ARM64 core, to enable PCI PROBE_ONLY systems on ARM64,
      this patch adds a pcibios_enable_device() arch implementation that
      simply prevents enabling resources on PROBE_ONLY systems (mirroring ARM
      behaviour).

      This is always a safe thing to do because on PROBE_ONLY systems the
      configuration space set-up can be considered immutable, and it is in
      preparation of proper resource claiming that would finally validate
      the PCI resources tree in the ARM64 arch implementation on PROBE_ONLY
      systems.

      For !PROBE_ONLY systems resources enablement in pcibios_enable_device()
      on ARM64 is implemented as in current PCI core, leaving the behaviour
      unchanged.

      arm64: cmpxchg: truncate sub-word signed types before comparison

      When performing a cmpxchg operation on a signed sub-word type (e.g. s8),
      we need to ensure that the upper register bits of the "old" value used
      for comparison are zeroed, otherwise we may erroneously fail the cmpxchg
      which may even be interpreted as success by the caller (if the compiler
      performs the truncation as part of its check). This has been observed
      in mod_state, where negative values where causing problems with
      this_cpu_cmpxchg.

      This patch fixes the issue by explicitly casting 8-bit and 16-bit "old"
      values using unsigned types in our cmpxchg wrappers. 32-bit types can be
      left alone, since the underlying asm makes use of W registers in this
      case.

      bpf: provide helper that indicates eBPF was migrated

      During recent discussions we had with Michael, we found that it would
      be useful to have an indicator that tells the JIT that an eBPF program
      had been migrated from classic instructions into eBPF instructions, as
      only in that case A and X need to be cleared in the prologue. Such eBPF
      programs do not set a particular type, but all have BPF_PROG_TYPE_UNSPEC.
      Thus, introduce a small helper for cde66c2d88da ("s390/bpf: Only clear
      A and X for converted BPF programs") and possibly others in future.

      test_bpf: assign type to native eBPF test cases

      As JITs start to perform optimizations whether to clear A and X on eBPF
      programs in the prologue, we should actually assign a program type to the
      native eBPF test cases. It doesn't really matter which program type, as
      these instructions don't go through the verifier, but it needs to be a
      type != BPF_PROG_TYPE_UNSPEC. This reflects eBPF programs loaded via 
bpf(2)
      system call (!= type unspec) vs. classic BPF to eBPF migrations (== type
      unspec).

      arm64: alternative: put secondary CPUs into polling loop during patch

      When patching the kernel text with alternatives, we may end up patching
      parts of the stop_machine state machine (e.g. atomic_dec_and_test in
      ack_state) and consequently corrupt the instruction stream of any
      secondary CPUs.

      This patch passes the cpu_online_mask to stop_machine, forcing all of
      the CPUs into our own callback which can place the secondary cores into
      a dumb (but safe!) polling loop whilst the patching is carried out.

      Input: touchscreen - export OF module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      This is determined by the audio bandwidth constraints of the endpoint.

      In current code, the wMaxPacketSize is defined as the maximum packet size
      for ISO endpoint, and it will let the host reserve much more space than
      it really needs, so that we can't let more endpoints work together at
      one frame.

      We find this issue when we try to let 4 f_uac2 gadgets work together [1]

      usb: dwc3: ep0: Fix mem corruption on OUT transfers of more than 512 bytes

      DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and
      the size of bounce buffer is 512 bytes. However if the host initiates OUT
      transfers of size more than 512 bytes (and non max packet aligned), the
      driver throws a WARN dump but still programs the TRB to receive more than
      512 bytes. This will cause bounce buffer to overflow and corrupt the
      adjacent memory locations which can be fatal.

      Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE
      (512) bytes.

      USB: pl2303: fix baud-rate divisor calculations

      This commit fixes the following issues:

      1. The 9th bit of buf was believed to be the LSB of divisor's
      exponent, but the hardware interprets it as MSB (9th bit) of the
      mantissa. The exponent is actually one bit shorter and applies
      to base 4, not 2 as previously believed.

      2. Loop iterations doubled the exponent instead of incrementing.

      3. The exponent wasn't checked for overflow.

      4. The function returned requested rate instead of actual rate.

      Due to issue #2, the old code deviated from the wrong formula
      described in #1 and actually yielded correct rates when divisor
      was lower than 4096 by using exponents of 0, 2 or 4 base-2,
      interpreted as 0, 1, 2 base-4 with the 9th mantissa bit clear.
      However, at 93.75 kbaud or less the rate turned out too slow
      due to #2 or too fast due to #2 and #3.

      I tested this patch by sending and validating 0x00,0x01,..,0xff
      to an FTDI dongle at 234, 987, 2401, 9601, 31415, 115199, 250k,
      500k, 750k, 1M, 1.5M, 3M+1 baud. All rates passed.

      I also used pv to check speed at some rates unsupported by FTDI:
      45 (the lowest possible), 2M, 4M, 5M and 6M-1. Looked sane.

      ath10k: initialize msdu ext. descriptor before use

      Initial QCA99X0 support has a known issue with TCP Tx throughput.
      All other path such as UDP Tx/Rx and TCP Rx meet their expectation
      (> 900Mbps), but TCP Tx marked as low as 5Mbps when single pair is
      used on iperf.

      The root cause is turned out because TSO flag is not initialized
      properly so that firmware configures TSO in wrong way.
      TSO flags in msdu extension descriptor is required to be reset
      to indicate firmware there is no TSO is enabled, otherwise it
      could act as TSO is enabled which causes huge throughput drop.

      In fact, it's enough by resetting TSO flags only to prevent the
      unexpected behavior, but initializing whole msdu ext. descriptor
      will help to clear uncertainty of firmware could bring on as it
      constantly updated.

      ath10k: fix memory alloc failure in qca99x0 during wmi svc rdy event

      Host memory required for firmware is allocated while handling
      wmi service ready event. Right now, wmi service ready is handled
      in tasklet context and it calls dma_alloc_coherent() with atomic
      flag (GFP_ATOMIC) to allocate memory in host needed for firmware.
      The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in
      the platform (at least in AP platform) where it has less atomic
      pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory
      for one card, having additional QCA99X0 card in the same platform
      will require similarly amount of memory. So, it's not guaranteed that
      all the platform will have enough atomic memory pool.

      Fix this issue, by handling wmi service ready event in workqueue
      context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work
      queue will not be ready at the time of handling wmi service ready.
      So, it can't be used to handle wmi service ready. Also, register work
      gets scheduled during insmod in existing ath10k_wq and waits for
      wmi service ready to completed. Both workqueue can't be used for
      this purpose. New auxiliary workqueue is added to handle wmi service
      ready.

      Bluetooth: 6lowpan: Fix possible race

      This patch fix a possible race after calling register_netdev. After
      calling netdev_register it could be possible that netdev_ops callbacks
      use the uninitialized private data of lowpan_dev. By moving the
      initialization of this data before netdev_register we can be sure that
      initialized private data is be used after netdev_register.

      mac802154: Fix memory corruption with global deferred transmit state.

      When transmitting a packet via a mac802154 driver that can sleep in
      its transmit function, mac802154 defers the call to the driver's
      transmit function to a per-device workqueue.

      However, mac802154 uses a single global work_struct for this, which
      means that if you have more than one registered mac802154 interface
      in the system, and you transmit on more than one of them at the same
      time, you'll very easily cause memory corruption.

      This patch moves the deferred transmit processing state from global
      variables to struct ieee802154_local, and this seems to fix the memory
      corruption issue.

      Bluetooth: btusb: match generic class code in interface descriptor

      btusb currently has a generic match on USB device descriptors:
              { USB_DEVICE_INFO(0xe0, 0x01, 0x01) },

      However, http://www.usb.org/developers/defined_class states:

        Base Class E0h (Wireless Controller)
        This base class is defined for devices that are Wireless controllers.
        Values not shown in the table below are reserved. These class codes are
        to be used in Interface Descriptors, with the exception of the Bluetooth
        class code which can also be used in a Device Descriptor.

      Add a match on the interface descriptors accordingly.

      This fixes compatibility with the RTL8723AU device shown below.
      This device conforms to the USB Interface Association Descriptor
      specification, which requires the device to have class ef/02/01.
      The extra IAD descriptor then specifies that interfaces 0 and 1
      belong to the same function/driver, which is true. Provided that
      the Bluetooth device class spec accepts use of the IAD, I imagine that
      technically, all btusb devices should be configured like this.

      netfilter: nf_ct_sctp: minimal multihoming support

      Currently nf_conntrack_proto_sctp module handles only packets between
      primary addresses used to establish the connection. Any packets between
      secondary addresses are classified as invalid so that usual firewall
      configurations drop them. Allowing HEARTBEAT and HEARTBEAT-ACK chunks to
      establish a new conntrack would allow traffic between secondary
      addresses to pass through. A more sophisticated solution based on the
      addresses advertised in the initial handshake (and possibly also later
      dynamic address addition and removal) would be much harder to implement.
      Moreover, in general we cannot assume to always see the initial
      handshake as it can be routed through a different path.

      The patch adds two new conntrack states:

        SCTP_CONNTRACK_HEARTBEAT_SENT  - a HEARTBEAT chunk seen but not acked
        SCTP_CONNTRACK_HEARTBEAT_ACKED - a HEARTBEAT acked by HEARTBEAT-ACK

      State transition rules:

      - HEARTBEAT_SENT responds to usual chunks the same way as NONE (so that
        the behaviour changes as little as possible)
      - HEARTBEAT_ACKED responds to usual chunks the same way as ESTABLISHED
        does, except the resulting state is HEARTBEAT_ACKED rather than
        ESTABLISHED
      - previously existing states except NONE are preserved when HEARTBEAT or
        HEARTBEAT-ACK is seen
      - NONE (in the initial direction) changes to HEARTBEAT_SENT on HEARTBEAT
        and to CLOSED on HEARTBEAT-ACK
      - HEARTBEAT_SENT changes to HEARTBEAT_ACKED on HEARTBEAT-ACK in the
        reply direction
      - HEARTBEAT_SENT and HEARTBEAT_ACKED are preserved on HEARTBEAT and
        HEARTBEAT-ACK otherwise

      Normally, vtag is set from the INIT chunk for the reply direction and
      from the INIT-ACK chunk for the originating direction (i.e. each of
      these defines vtag value for the opposite direction). For secondary
      conntracks, we can't rely on seeing INIT/INIT-ACK and even if we have
      seen them, we would need to connect two different conntracks. Therefore
      simplified logic is applied: vtag of first packet in each direction
      (HEARTBEAT in the originating and HEARTBEAT-ACK in reply direction) is
      saved and all following packets in that direction are compared with this
      saved value. While INIT and INIT-ACK define vtag for the opposite
      direction, vtags extracted from HEARTBEAT and HEARTBEAT-ACK are always
      for their direction.

      Default timeout values for new states are

        HEARTBEAT_SENT: 30 seconds (default hb_interval)
        HEARTBEAT_ACKED: 210 seconds (hb_interval * path_max_retry + max_rto)

      (We cannot expect to see the shutdown sequence so that, unlike
      ESTABLISHED, the HEARTBEAT_ACKED timeout shouldn't be too long.)

      Introduce Mellanox Technologies Switch ASICs switchdev drivers

      This patchset introduces Mellanox Technologies Switch driver 
infrastructure
      and support for SwitchX-2 ASIC.

      The driver is divided into 3 logical parts:
      1) Bus - implements switch bus interface. Currently only PCI bus is
         implemented, but more buses will be added in the future. Namely I2C
         and SGMII.
         (patch #2)
      2) Driver - implemements of ASIC-specific functions.
         Currently SwitchX-2 ASIC is supported, but a plan exists to introduce
         support for Spectrum ASIC in the near future.
         (patch #4)
      3) Core - infrastructure that glues buses and drivers together.
         It implements register access logic (EMADs) and takes care of RX traps
         and events.
         (patch #1 and #3)

      mlxsw: Add interface to access registers and process events

      Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
      the host and the device in order to configure the available device 
registers.
      Another use case is notifications sent from the device to the host,
      letting it know about certain events, such as port up / down.

      Add the ability to construct EMADs with provisions to construct and
      parse the registers' payloads. Implement EMAD transaction layer
      which is responsible for the reliable transmission of EMADs. Also, add
      an infrastructure used by the switch driver to register for particular
      events generated by the device.

      drm/amdkfd: fix bug when initializing sdma vm

      A logical AND operation was used during mask and shift, instead of a
      bitwise AND operation. This patch fixes this bug by changing the
      operation to bitwise AND.

      bnx2x: add vlan filtering offload

      Current driver always uses vlan-promisc mode, i.e., it receives both
      tagged and untagged traffic and lets the network stack drop packets
      tagged with unrequested vlan tags.

      This patch implements vlan-filtering offload in the driver -
      Unless explicitly configured to promisc mode, only untagged packets or
      packets tagged with requested vlans would reach the Rx flow.

      net/mlx5e: Remove the mlx5e_update_priv_params() function

      It was used to update netdev priv parameters that require stopping
      and re-opening the device in a generic way - it got the new
      parameters and did: ndo_stop(), copy new parameters into current
      parameters, ndo_open().

      We chose to remove it for two reasons:
      1) It requires additional instance of struct mlx5e_params on the
         stack and looking forward we expect this struct to grow.
      2) Sometimes we want to do additional operations (besides
         just updating the priv parameters) while the netdev is stopped.
         For example, updating netdev->mtu @mlx5e_change_mtu() should
         be done while the netdev is stopped (done in this commit).

      gianfar: Fix warnings when built on 64-bit

      As part of defconfig consolidation using fragments, we'd like to be
      able to have the same drivers enabled on 32-bit and 64-bit.  Gianfar
      happens to only exist on 32-bit systems, and when building the
      resulting 64-bit kernel warnings were produced.

      A couple of the warnings are trivial, but the rfbptr code has deeper
      issues.  It uses the virtual address as the DMA address, which again,
      happens to work in the environments where this driver is currently
      used, but is not the right thing to do.

      When a connection is failing a transport protocol calls
      dst_negative_advice to try to get a better route. This patch includes
      changing the sk_txhash in that function. This provides a rudimentary
      method to try to find a different path in the network since sk_txhash
      affects ECMP on the local host and through the network (via flow labels
      or UDP source port in encapsulation).

      powerpc/kernel: Enable seccomp filter

      This commit enables seccomp filter on powerpc, now that we have all the
      necessary pieces in place.

      To support seccomp's desire to modify the syscall return value under
      some circumstances, we use a different ABI to the ptrace ABI. That is we
      use r3 as the syscall return value, and orig_gpr3 is the first syscall
      parameter.

      This means the seccomp code, or a ptracer via SECCOMP_RET_TRACE, will
      see -ENOSYS preloaded in r3. This is identical to the behaviour on x86,
      and allows seccomp or the ptracer to either leave the -ENOSYS or change
      it to something else, as well as rejecting or not the syscall by
      modifying r0.

      If seccomp does not reject the syscall, we restore the register state to
      match what ptrace and audit expect, ie. r3 is the first syscall
      parameter again. We do this restore using orig_gpr3, which may have been
      modified by seccomp, which allows seccomp to modify the first syscall
      paramater and allow the syscall to proceed.

      We need to #ifdef the the additional handling of r3 for seccomp, so move
      it all out of line.

      tipc: fix bug in broadcast synch message create function

      In commit d999297c3dbbe7fdd832f7fa4ec84301e170b3e6
      ("tipc: reduce locking scope during packet reception") we introduced
      a new function tipc_build_bcast_sync_msg(), which carries initial
      synchronization data between two nodes at first contact and at
      re-contact. In this function, we missed to add synchronization data,
      with the effect that the broadcast link endpoints will fail to
      synchronize correctly at re-contact between a running and a restarted
      node. All other cases work as intended.

      With this commit, we fix this bug.

      This also enables us to implement callbacks for new states of clockevent

      irqchip/gicv3-its: Split PCI/MSI code from the core ITS driver

      It is becoming obvious that having the PCI/MSI code in the same
      file as the the core ITS code is giving people implementing non-PCI
      MSI support the wrong kind of idea.

      In order to make things a bit clearer, let's move the PCI/MSI code
      out to its own file. Hopefully it will make it clear that whoever
      thinks of hooking into the core ITS better have a very strong point.

      We use a temporary entry point that will get removed in a subsequent
      patch, once the proper infrastructure is added.

      drivers/base: Add MSI domain support for non-PCI devices

      With the msi_list and the msi_domain properties now being at the
      generic device level, it is starting to be relatively easy to offer
      a generic way of providing non-PCI MSIs.

      The two major hurdles with this idea are:

      - Lack of global ID that identifies a device: this is worked around by
        having a global ID allocator for each device that gets enrolled in
        the platform MSI subsystem

      - Lack of standard way to write the message in the generating device.
        This is solved by mandating driver code to provide a write_msg
        callback, so that everyone can have their own square wheel

      Apart from that, the API is fairly straightforward:

      - platform_msi_create_irq_domain creates an MSI domain that gets
        tagged with DOMAIN_BUS_PLATFORM_MSI

      - platform_msi_domain_alloc_irqs allocate MSIs for a given device,
        populating the msi_list

      - platform_msi_domain_free_irqs does what is written on the tin

      [ tglx: Created a seperate struct platform_msi_desc and added
                kerneldoc entries ]

      Allow this configuration by performing an irq domain lookup based
      on the host bridge node if it doesn't have a valid msi-parent property.

      PCI/MSI: Add support for OF-provided msi_domain

      In order to populate the PCI host bridge msi_domain, use the
      "msi-parent" attribute to lookup a corresponding irq domain.
      If found, this is our MSI domain.

      This gets plugged into the core PCI code.

      As MSI-type features are creeping into non-PCI devices, it is
      starting to make sense to give our struct device some form of
      support for this, by allowing a pointer to an MSI irq domain to
      be set/retrieved.

      genirq/irqdomain: Allow irq domain aliasing

      It is not uncommon (at least with the ARM stuff) to have a piece
      of hardware that implements different flavours of "interrupts".
      A typical example of this is the GICv3 ITS, which implements
      standard PCI/MSI support, but also some form of "generic MSI".

      So far, the PCI/MSI domain is registered using the ITS device_node,
      so that irq_find_host can return it. On the contrary, the raw MSI
      domain is not registered with an device_node, making it impossible
      to be looked up by another subsystem (obviously, using the same
      device_node twice would only result in confusion, as it is not
      defined which one irq_find_host would return).

      A solution to this is to "type" domains that may be aliasing, and
      to be able to lookup an device_node that matches a given type.
      For this, we introduce irq_find_matching_host() as a superset
      of irq_find_host:

      struct irq_domain *irq_find_matching_host(struct device_node *node,
                                      enum irq_domain_bus_token bus_token);

      where bus_token is the "type" we want to match the domain against
      (so far, only DOMAIN_BUS_ANY is defined). This result in some
      moderately invasive changes on the PPC side (which is the only
      user of the .match method).

      This has otherwise no functionnal change.

      This data is cached by s390 JIT to improve performance of ld_abs/ld_ind
      instructions. Therefore after a change we have to reload the data.

      In case of usage of skb_vlan_push/pop, in the prologue we store
      the SKB pointer on the stack and restore it after BPF_JMP_CALL
      to skb_vlan_push/pop.

      Currently we have the restriction that jitted BPF programs can

      The 20 bit displacements are available since z990 and BPF requires
      z196 as minimum. Therefore we can remove this restriction and use
      everywhere 20 bit signed long displacements.

      s390/bpf: Fix multiple macro expansions

      The EMIT6_DISP_LH macro passes the "disp" parameter to the _EMIT6_DISP_LH
      macro. The _EMIT6_DISP_LH macro uses the "disp" parameter twice:

       unsigned int __disp_h = ((u32)disp) & 0xff000;
       unsigned int __disp_l = ((u32)disp) & 0x00fff;

      The EMIT6_DISP_LH is used several times with EMIT_CONST_U64() as "disp"
      parameter. Therefore always two constants are created per usage of
      EMIT6_DISP_LH.

      Fix this and add variable "_disp" to avoid multiple expansions.

      * v2: Move "_disp" to _EMIT6_DISP_LH as suggested by Joe Perches

      Unfortunately this mapping is wrong. The correct mapping is:

       - BPF_REG_X -> BPF_REG_7

      So clear the correct registers and use the BPF_REG_A and BPF_REG_X

      PCI: iproc: Add arm64 support

      Add arm64 support to the iProc PCIe driver.

      Note that on arm32, bus->sysdata points to the arm32-specific
      pci_sys_data struct, and pci_sys_data.private_data contains the
      iproc_pcie pointer. For arm64, there's nothing corresponding to
      pci_sys_data, so we keep the iproc_pcie pointer directly in
      bus->sysdata.

      In addition, arm64 does IRQ mapping in pcibios_add_device(), so it
      doesn't need pci_fixup_irqs() as arm32 does.

      x86/pci/intel_mid_pci: Work around for IRQ0 assignment

      On Intel Tangier the MMC host controller is wired up to irq 0. But
      several other devices have irq 0 associated as well due to a bogus PCI
      configuration.

      The first initialized driver will acquire irq 0 and make it
      unavailable for other devices. If the sdhci driver is not the first
      one it will fail to acquire the interrupt and therefor be non
      functional.

      Add a quirk to the pci irq enable function which denies irq 0 to
      anything else than the MMC host controller driver on Tangier
      platforms.

      perf tools: Force period term to overload global settings

      Currently the command line option settings beats the per event period
      settings:

      With no global settings, we get per-event configuration:

        $ perf record -e 'cpu/instructions,period=20000/' sleep 1
        $ perf evlist -v
        ... { sample_period, sample_freq }: 20000 ...

      With 'c' option period setup, we get 'c' option value:
        $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
        $ perf evlist -v
        ... { sample_period, sample_freq }: 1000 ...

      This patch makes the per-event settings overload the global 'c' option
      setup:

        $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
        $ perf evlist -v
        ... { sample_period, sample_freq }: 20000 ...

      I think the making the per-event settings to overload any other config
      makes more sense than current state. However it breaks the current
      'period' term handling, which might cause some noise.. so let's see ;-).

      Also fixing parse event tests with the new behaviour.

      spi: bcm2835: set up spi-mode before asserting cs-gpio

      When using reverse polarity for clock (spi-cpol) on a device
      the clock line gets altered after chip-select has been asserted
      resulting in an additional clock beat, which confuses hardware.

      This did not show when using native-CS, as the same register
      is used to control cs as well as polarity, so the changes came
      into effect at the same time. Unfortunately this is not true
      with gpio-cs.

      To avoid this situation this patch moves the setup of polarity
      (spi-cpol and spi-cpha) outside of the chip-select into
      prepare_message, which is run prior to asserting chip-select.

      Also fixes resetting 3-wire mode after use of rx-mode, so that
      a 3-Wire sequence TX, RX, TX works as well (right now it runs
      TX, RX, RX instead)

      perf session env: Rename exit method

      The semantic associated in tools/perf/ with foo__delete(instance) is to
      release all resources referenced by 'instance' members and then release
      the memory for 'instance' itself.

      The perf_session_env__delete() function isn't doing this, it just does
      the first part, but the space used by 'instance' itself isn't freed, as
      it is embedded in a larger structure, that will be freed at other stage.

      For these cases we se foo__exit(), i.e. the usage is:

       void foo__delete(foo)
       {
               if (foo) {
                       foo__exit(foo);
                       free(foo);
               }
       }

      But when we have something like:

       struct bar {
               struct foo foo;
               . . .
       }

      Then we can't really call foo__delete(&bar.foo), we must have this
      instead:

       void bar__exit(bar)
       {
               foo__exit(&bar.foo);
               /* free other bar-> resources */
       }

       void bar__delete(bar)
       {
               if (bar) {
                bar__exit(bar);
                      free(bar);
               }
       }

      So just rename perf_session_env__delete() to perf_session_env__exit().

      btrfs: add missing discards when unpinning extents with -o discard

      When we clear the dirty bits in btrfs_delete_unused_bgs for extents
      in the empty block group, it results in btrfs_finish_extent_commit being
      unable to discard the freed extents.

      The block group removal patch added an alternate path to forget extents
      other than btrfs_finish_extent_commit.  As a result, any extents that
      would be freed when the block group is removed aren't discarded.  In my
      test run, with a large copy of mixed sized files followed by removal, it
      left nearly 2/3 of extents undiscarded.

      To clean up the block groups, we add the removed block group onto a list
      that will be discarded after transaction commit.

      btrfs: explictly delete unused block groups in close_ctree and ro-remount

      The cleaner thread may already be sleeping by the time we enter
      close_ctree.  If that's the case, we'll skip removing any unused
      block groups queued for removal, even during a normal umount.
      They'll be cleaned up automatically at next mount, but users
      expect a umount to be a clean synchronization point, especially
      when used on thin-provisioned storage with -odiscard.  We also
      explicitly remove unused block groups in the ro-remount path
      for the same reason.

      btrfs: iterate over unused chunk space in FITRIM

      Since we now clean up block groups automatically as they become
      empty, iterating over block groups is no longer sufficient to discard
      unused space.

      This patch iterates over the unused chunk space and discards any regions
      that are unallocated, regardless of whether they were ever used.  This is
      a change for btrfs but is consistent with other file systems.

      We do this in a transactionless manner since the discard process can take
      a substantial amount of time and a transaction would need to be started
      before the acquisition of the device list lock.  That would mean a
      transaction would be held open across /all/ of the discards collectively.
      In order to prevent other threads from allocating or freeing chunks, we
      hold the chunks lock across the search and discard calls.  We release it
      between searches to allow the file system to perform more-or-less
      normally.  Since the running transaction can commit and disappear while
      we're using the transaction pointer, we take a reference to it and
      release it after the search.  This is safe since it would happen normally
      at the end of the transaction commit after any locks are released anyway.
      We also take the commit_root_sem to protect against a transaction starting
      and committing while we're running.

      btrfs: skip superblocks during discard

      Btrfs doesn't track superblocks with extent records so there is nothing
      persistent on-disk to indicate that those blocks are in use.  We track
      the superblocks in memory to ensure they don't get used by removing them
      from the free space cache when we load a block group from disk.  Prior
      to 47ab2a6c6a (Btrfs: remove empty block groups automatically), that
      was fine since the block group would never be reclaimed so the superblock
      was always safe.  Once we started removing the empty block groups, we
      were protected by the fact that discards weren't being properly issued
      for unused space either via FITRIM or -odiscard.  The block groups were
      still being released, but the blocks remained on disk.

      In order to properly discard unused block groups, we need to filter out
      the superblocks from the discard range.  Superblocks are located at fixed
      locations on each device, so it makes sense to filter them out in
      btrfs_issue_discard, which is used by both -odiscard and FITRIM.

      btrfs: btrfs_issue_discard ensure offset/length are aligned to sector 
boundaries

      It's possible, though unexpected, to pass unaligned offsets and lengths
      to btrfs_issue_discard.  We then shift the offset/length values to sector
      units.  If an unaligned offset has been passed, it will result in the
      entire sector being discarded, possibly losing data.  An unaligned
      length is safe but we'll end up returning an inaccurate number of
      discarded bytes.

      This patch aligns the offset to the 512B boundary, adjusts the length,
      and warns, since we shouldn't be discarding on an offset that isn't
      aligned with our sector size.

      usb: composite: add bind_deactivated flag to usb_function

      This patch introduces 'bind_deactivated' flag in struct usb_function.
      Functions which don't want to be activated automatically after bind should
      set this flag, and when they start to be ready to work they should call
      usb_function_activate().

      When USB function sets 'bind_deactivated' flag, initial deactivation
      counter is incremented automatically, so there is no need to call
      usb_function_deactivate() in function bind.

      usb: composite: fix usb_function_activate/deactivate functions

      Using usb_gadget_disconnect to make gadget temporarily invisible to host
      doesn't provide desired result, because gadget is connected immediately
      after binding regardless to previous usb_gadget_disconnect() calls.

      For this reason we use usb_gadget_deactivate() instead of
      usb_gadget_disconnect() to make it working as expected.

      usb: dwc3: core: remove unnecessary dev_warn()

      When a SoC supports both PHY interfaces but
      doesn't define HSPHY in DT/pdata, we will get
      an unnecessary dev_warn() which can mislead users
      into thinking that they're missing something.

      Instead, let's just silently rely on a correct
      default. If the HW default is wrong, then HSPHY
      is required and USB won't work, this will be
      motivation enough for engineers to patch their
      way into a working setup.

      which appeared in v3.17-rc1, the gpiod_get* functions take an additional
      parameter that allows to specify direction and initial value for output.

      Currently this parameter is made optional with the help of a cpp trick.
      To allow dropping this hack convert callers to explictly pass a value

      Use this additional parameter and the _optional variant to simplify the

      why it's not sensible to switch to devm_gpiod_get and why the gpiod_put
      is also necessary.

      Furthermore this is one caller less that stops us making the flags

      block: shrink struct bio down to 2 cache lines again

      Commit bcf2843b3f8f added ->bi_error to cleanup the error passing
      for struct bio, but that ended up adding 4 bytes and a 4 byte hole
      to the size of struct bio. For a clean config, that bumped it from
      128 bytes, to 136 bytes, on x86-64.

      The ->bi_flags member is currently an unsigned long, but it fits
      easily within an int. Change it to an unsigned int, adjust the
      the pool offset code, and move ->bi_error into the new hole. Then
      we end up with a 128 byte bio again.

      Change the bio flag set/clear to use cmpxchg to ensure we don't
      lose any flags when manipulating them.

      block: manipulate bio->bi_flags through helpers

      Some places use helpers now, others don't. We only have the 'is set'
      helper, add helpers for setting and clearing flags too.

      It was a bit of a mess of atomic vs non-atomic access. With
      BIO_UPTODATE gone, we don't have any risk of concurrent access to the
      flags. So relax the restriction and don't make any of them atomic. The
      flags that do have serialization issues (reffed and chained), we
      already handle those separately.

  Date:   Mon Jul 20 15:29:37 2015 +0200

      block: add a bi_error field to struct bio

      Currently we have two different ways to signal an I/O error on a BIO:

       (1) by clearing the BIO_UPTODATE flag
       (2) by returning a Linux errno value to the bi_end_io callback

      The first one has the drawback of only communicating a single possible
      error (-EIO), and the second one has the drawback of not beeing persistent
      when bios are queued up, and are not passed along from child to parent
      bio in the ever more popular chaining scenario.  Having both mechanisms
      available has the additional drawback of utterly confusing driver authors
      and introducing bugs where various I/O submitters only deal with one of
      them, and the others have to add boilerplate code to deal with both kinds
      of error returns.

      So add a new bi_error field to store an errno value directly in struct
      bio and remove the existing mechanisms to clean all this up.

      Use regmap helpers for get_voltage_sel and set_voltage_sel ops

      The DVS GPIO allows on the fly selection of the VSEL register
      from two choices. However, if it is not set, the VSEL register
      will stay fixed and we can use the regmap ops. This allows use
      of the *hardware_vsel* regulator APIs.

      perf python: Remove dependency on 'machine' methods

      The python binding still doesn't provide symbol resolving facilities,
      but the recent addition of the trace_event__register_resolver() function
      made it add as a dependency the machine__resolve_kernel_addr() method,
      that in turn drags all the symbol resolving code.

      The problem:

        [root@zoo ~]# perf test -v python
        17: Try 'import perf' in python, checking link problems      :
        --- start ---
        test child forked, pid 6853
        Traceback (most recent call last):
          File "<stdin>", line 1, in <module>
        ImportError: /tmp/build/perf/python/perf.so: undefined symbol:

        test child finished with -1
        ---- end ----
        Try 'import perf' in python, checking link problems: FAILED!
        [root@zoo ~]#

      Fix it by requiring this function to receive the resolver as a
      parameter, just like pevent_register_function_resolver(), i.e. do
      not explicitely refer to an object file not included in
      tools/perf/util/python-ext-sources.

      spi: img-spfi: check for timeout error before proceeding

      Calling spfi_wait_all_done is not required if the transfer has timed
      out before all data is transferred.

      spfi_wait_all_done polls for Alldone interrupt which is triggered to
      mark the transfer as complete and to indicate it is now safe to issue
      a new transfer.

      nohz: Restart nohz full tick from irq exit

      Restart the tick when necessary from the irq exit path. It makes nohz
      full more flexible, simplify the related IPIs and doesn't bring
      significant overhead on irq exit.

      In a longer term view, it will allow us to piggyback the nohz kick
      on the scheduler IPI in the future instead of sending a dedicated IPI
      that often doubles the scheduler IPI on task wakeup. This will require
      more changes though including careful review of resched_curr() callers
      to include nohz full needs.

      nohz: Remove idle task special case

      On nohz full early days, idle dynticks and full dynticks weren't well
      integrated and we couldn't risk full dynticks calls on idle without
      risking messing up tick idle statistics. This is why we prevented such
      thing to happen.

      Nowadays full dynticks and idle dynticks are better integrated and
      interact without known issue.

      So lets remove that.

      nohz: Prevent tilegx network driver interrupts

      Normally the tilegx networking shim sends irqs to all the cores
      to distribute the load of processing incoming-packet interrupts,
      so that you can get to multiple Gb's of traffic inbound.

      However, in nohz_full mode we don't want to interrupt the
      nohz_full cores by default, so we limit the set of cores we use
      to only the online housekeeping cores.

      To make client code easier to read, we introduce a new nohz_full
      accessor, housekeeping_cpumask(), which returns a pointer to the
      housekeeping_mask if nohz_full is enabled, and otherwise returns
      the cpu_possible_mask.

      ASoC: dapm: Simplify list creation in dapm_dai_get_connected_widgets()

      When running dapm_dai_get_connected_widgets() currently in
      is_connected_{input,output}_ep() for each widget that gets added the array
      is resized and the code also loops over all existing entries to avoid
      adding a widget multiple times.

      The former can be avoided by collecting the widgets in a linked list and
      only once we have all widgets allocate the array.

      The later can be avoided by changing when the widget is added. Currently 
it
      is added when walking the neighbor lists of a widget. Since a widget can 
be
      neighbors with multiple other widgets it could get added twice and hence
      the check is necessary. But the main body of 
is_connected_{input,output}_ep
      is guaranteed to be only executed at most once per widget. So adding the
      widget to the list at the beginning of the function automatically makes
      sure that each widget gets only added once. The only difference is that
      using this method the starting point itself will also end up on the list,
      but it can easily be skipped when creating the array.

      Overall this reduces the code size and speeds things slightly up.

      KVM: s390: remove "from (user|kernel)" from irq injection messages

      The "from user"/"from kernel" part of the log/trace messages is not
      always correct anymore and therefore not really helpful.

      Let's remove that part from the log + trace messages. For program
      interrupts, we can now move the logging/tracing part into the real
      injection function, as already done for the other injection functions.

      KVM: s390: VCPU_EVENT cleanup for prefix changes

      SPX (SET PREFIX)  and SIGP (Set prefix) can change the prefix
      register of a CPU. As sigp set prefix may be handled in user
      space (KVM_CAP_S390_USER_SIGP), we would not log the changes
      triggered via SIGP in that case. Let's have just one VCPU_EVENT

      KVM: s390: filter space-switch events when PER is enforced

      When guest debugging is active, space-switch events might be enforced
      by PER. While the PER events are correctly filtered out,
      space-switch-events could be forwarded to the guest, although from a
      guest point of view, they should not have been reported.

      Therefore we have to filter out space-switch events being concurrently
      reported with a PER event, if the PER event got filtered out. To do so,
      we theoretically have to know which instruction was responsible for the
      event. As the applicable instructions modify the PSW address, the
      address space set in the PSW and even the address space in cr1, we
      can't figure out the instruction that way.

      For this reason, we have to rely on the information about the old and
      new address space, in order to guess the responsible instruction type
      and do appropriate checks for space-switch events.

      ath10k: enable raw encap mode and software crypto engine

      This patch enables raw Rx/Tx encap mode to support software based
      crypto engine. This patch introduces a new module param 'cryptmode'.

       cryptmode:

         0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
            encapsulation to the firmware. This is the default mode.
         1: Use sofware crypto engine globally with raw mode TX/RX
            encapsulation to the firmware.

      Known limitation:
         A-MSDU must be disabled for RAW Tx encap mode to perform well when
         heavy traffic is applied.

      ath10k: suppress 'failed to process fft' warning messages

      When using DFS channels on Ath10k, kernel log has repeated warning message
      'failed to process fft: -22' typically under medium/heavy traffic.

      This patch switches the warnings to driver debug (WMI events) mode only
      thus reducing log file noise.

      DFS and spectral scan share underlying HW mechanisms and enabling one
      (DFS) enables the other (spectral scan) as far as event reporting from
      firmware to driver is concerned. Spectral scan events take no part in
      processing of DFS radar pulses which are delivered as distinct events,
      so the fft (spectral event) warning is harmless and DFS interference
      detection/protection still occurs.

      Symptoms seen & fix tested in both debug & non-debug modes on TP-Link
      Archer C7 v2 platform.

      arch/*/io.h: Add ioremap_uc() to all architectures

      This adds ioremap_uc() only for architectures that do not
      include asm-generic.h/io.h as that already provides a default
      definition for them for both cases where you have CONFIG_MMU
      and you do not, and because of this, the number of architectures
      this patch address is less than the architectures that the
      ioremap_wt() patch addressed, "arch/*/io.h: Add ioremap_wt() to
      all architectures").

      In order to reduce the number of architectures we have to
      modify by adding new architecture IO APIs we'll have to review
      the architectures in this patch, see why they can't add
      asm-generic.h/io.h or issues that would be created by doing
      so and then spread a consistent inclusion of this header
      towards the end of their own header. For instance arch/metag
      includes the asm-generic/io.h *before* the ioremap*()
      definitions, this should be the other way around but only
      once we have guard wrappers for the non-MMU case also for
      asm-generic/io.h.

      Merge branch 'stmmac-cleanup'

      Joachim Eastwood says:

      ====================
      stmmac clean up for 4.3 part2

      This patch set creates proper probe functions in the remaining
      dwmac-* drivers, lets the drivers manage their own of match data
      structure, and cleans up some of the drivers a bit. Note that
      should be no functional change in any of the drivers.

      First patch from Fengguang fixes a Coccinelle that was found after
      the previous patch set when into next.

      Probe functions are best placed just above the platform_driver
      struct since it usually needs to call other functions in the
      driver but this requires some code movement in the drivers. To
      keep the conversion itself easier to review the code movement is
      done in separate patches. This creates some extra churn but I
      think it's worth it in this case.

      As only a couple of drivers actually needs to use of match data
      this pushed down from stmmac_platform and into the drivers. This
      also makes it possible for drivers to have their own match data
      structure. dwmac-rk benefits most from this.

      After each driver has it's own probe function and manages it's
      own match data the setup/free hooks and common match data struct
      are removed.

      Sorry for the slightly largish patch set this time around.

      Since I can only test the core changes on my platform and not the
      specific dwmac-drivers I greatly appreciate if people could test
      this on their respective platforms. I did spend quite a bit of
      time visually checking all these patches, but nothing beats real
      hardware testing. Thanks!

      As all dwmac-* drivers have been converted to have a proper probe
      function the setup callback can now be removed. Also remove the

      it supports:
      * TSO
      * Checksum offload for RX and TX.
      * Energy efficient ethernet.
      * GMII phy interface.

      powerpc/kernel: Add SIG_SYS support for compat tasks

      SIG_SYS was added in commit a0727e8ce513 "signal, x86: add SIGSYS info
      and make it synchronous."

      Because we use the asm-generic struct siginfo, we got support for
      SIG_SYS for free as part of that commit.

      However there was no compat handling added for powerpc. That means we've
      been advertising the existence of signfo._sifields._sigsys to compat
      tasks, but not actually filling in the fields correctly.

      Luckily it looks like no one has noticed, presumably because the only
      user of SIGSYS in the kernel is seccomp filter, which we don't support
      yet.

      So before we enable seccomp filter, add compat handling for SIGSYS.

      powerpc: Change syscall_get_nr() to return int

      The documentation for syscall_get_nr() in asm-generic says:

       Note this returns int even on 64-bit machines. Only 32 bits of
       system call number can be meaningful. If the actual arch value
       is 64 bits, this truncates to 32 bits so 0xffffffff means -1.

      However our implementation was never updated to reflect this.

      Generally it's not important, but there is once case where it matters.

      For seccomp filter with SECCOMP_RET_TRACE, the tracer will set
      regs->gpr[0] to -1 to reject the syscall. When the task is a compat
      task, this means we end up with 0xffffffff in r0 because ptrace will
      zero extend the 32-bit value.

      If syscall_get_nr() returns an unsigned long, then a 64-bit kernel will
      see a positive value in r0 and will incorrectly allow the syscall
      through seccomp.

      powerpc: Use orig_gpr3 in syscall_get_arguments()

      Currently syscall_get_arguments() is used by syscall tracepoints, and
      collect_syscall() which is used in some debugging as well as
      /proc/pid/syscall.

      The current implementation just copies regs->gpr[3 .. 5] out, which is
      fine for all the current use cases.

      When we enable seccomp filter, that will also start using
      syscall_get_arguments(). However for seccomp filter we want to use r3
      as the return value of the syscall, and orig_gpr3 as the first
      parameter. This will allow seccomp to modify the return value in r3.

      To support this we need to modify syscall_get_arguments() to return
      orig_gpr3 instead of r3. This is safe for all uses because orig_gpr3
      always contains the r3 value that was passed to the syscall. We store it
      in the syscall entry path and never modify it.

      Update syscall_set_arguments() while we're here, even though it's never
      used.

      This means we have not noticed that our implementation of

      It also doesn't deal with compat, and doesn't deal with TIF_NOERROR.

      powerpc/kernel: Change the do_syscall_trace_enter() API

      The API for calling do_syscall_trace_enter() is currently sensible
      enough, it just returns the (modified) syscall number.

      However once we enable seccomp filter it will get more complicated. When
      seccomp filter runs, the seccomp kernel code (via SECCOMP_RET_ERRNO), or
      a ptracer (via SECCOMP_RET_TRACE), may reject the syscall and *may* or may
      *not* set a return value in r3.

      That means the assembler that calls do_syscall_trace_enter() can not
      blindly return ENOSYS, it needs to only return ENOSYS if a return value
      has not already been set.

      There is no way to implement that logic with the current API. So change
      the do_syscall_trace_enter() API to make it deal with the return code
      juggling, and the assembler can then just return whatever return code it
      is given.

      powerpc/kernel: Switch to using MAX_ERRNO

      Currently on powerpc we have our own #define for the highest (negative)
      errno value, called _LAST_ERRNO. This is defined to be 516, for reasons
      which are not clear.

      The generic code, and x86, use MAX_ERRNO, which is defined to be 4095.

      In particular seccomp uses MAX_ERRNO to restrict the value that a
      seccomp filter can return.

      Currently with the mismatch between _LAST_ERRNO and MAX_ERRNO, a seccomp
      tracer wanting to return 600, expecting it to be seen as an error, would
      instead find on powerpc that userspace sees a successful syscall with a
      return value of 600.

      To avoid this inconsistency, switch powerpc to use MAX_ERRNO.

      We are somewhat confident that generic syscalls that can return a
      non-error value above negative MAX_ERRNO have already been updated to
      use force_successful_syscall_return().

      I have also checked all the powerpc specific syscalls, and believe that
      none of them expect to return a non-error value between -MAX_ERRNO and
      -516. So this change should be safe ...

      xfs: create new metadata UUID field and incompat flag

      This adds a new superblock field, sb_meta_uuid.  If set, along with
      a new incompat flag, the code will use that field on a V5 filesystem
      to compare to metadata UUIDs, which allows us to change the user-
      visible UUID at will.  Userspace handles the setting and clearing
      of the incompat flag as appropriate, as the UUID gets changed; i.e.
      setting the user-visible UUID back to the original UUID (as stored in
      the new field) will remove the incompatible feature flag.

      If the incompat flag is not set, this copies the user-visible UUID into
      into the meta_uuid slot in memory when the superblock is read from disk;
      the meta_uuid field is not written back to disk in this case.

      The remainder of this patch simply switches verifiers, initializers,
      etc to use the new sb_meta_uuid field.

      xfs: validate transaction header length on log recovery

      When log recovery hits a new transaction, it copies the transaction
      header from the expected location in the log to the in-core structure
      using the length from the op record header. This length is validated to
      ensure it doesn't exceed the length of the record, but not against the
      expected size of a transaction header (and thus the size of the in-core
      structure). If the on-disk length is corrupted, the associated memcpy()
      can overflow, write to unrelated memory and lead to crashes. This has
      been reproduced via filesystem fuzzing.

      The code currently handles the possibility that the transaction header
      is split across two op records. Neither instance accounts for corruption
      where the op record length might be larger than the in-core transaction
      header. Update both sites to detect such corruption, warn and return an
      error from log recovery. Also add some comments and assert that if the
      record is split, the copy of the second portion is less than a full
      header. Otherwise, this suggests the copy of the second portion could
      have overwritten bits from the first and thus that something could be
      wrong.

      xfs: close xc_cil list_empty() races with cil commit sequence

      We have seen somewhat rare reports of the following assert from
      xlog_cil_push_background() failing during ltp tests or somewhat
      innocuous desktop root fs workloads (e.g., virt operations, initramfs
      construction):

          ASSERT(!list_empty(&cil->xc_cil));

      The reasoning behind the assert is that the transaction has inserted
      items to the CIL and hit background push codepath all with
      cil->xc_ctx_lock held for reading. This locks out background commit from
      emptying the CIL, which acquires the lock for writing. Therefore, the
      reasoning is that the items previously inserted in the CIL should still
      be present.

      The cil->xc_ctx_lock read lock is not sufficient to protect the xc_cil
      list, however, due to how CIL insertion is handled.
      xlog_cil_insert_items() inserts and reorders the dirty transaction items
      to the tail of the CIL under xc_cil_lock. It uses list_move_tail() to
      achieve insertion and reordering in the same block of code. This
      function removes and reinserts an item to the tail of the list. If a
      transaction commits an item that was already logged and thus already
      resides in the CIL, and said item is the sole item on the list, the
      removal and reinsertion creates a temporary state where the list is
      actually empty.

      This state is not valid and thus should never be observed by concurrent
      transaction commit-side checks in the circumstances outlined above. We
      do not want to acquire the xc_cil_lock in all of these instances as it
      was previously removed and replaced with a separate push lock for
      performance reasons. Therefore, close any races with list_empty() on the
      insertion side by ensuring that the list is never in a transient empty
      state.

      clk: exynos4: Fix wrong clock for Exynos4x12 ADC

      The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver.
      However TSADC is present only on Exynos4210 so on Trats2 board (with
      Exynos4412 SoC) the exynos-adc driver could not be probed:
         ERROR: could not get clock /adc@126C0000:adc(0)
         exynos-adc 126c0000.adc: failed getting clock, err = -2
         exynos-adc: probe of 126c0000.adc failed with error -2

      Instead on Exynos4x12 SoCs the main clock used by Analog to Digital
      Converter is located in different register and it is named in datasheet
      as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock
      is the same as purpose of TSADC from Exynos4210.

      The patch adds gate clock for Exynos4x12 using the proper register so
      backward compatibility is preserved. This fixes the probe of exynos-adc
      driver on Exynos4x12 boards and allows accessing sensors connected to it
      on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

      clk: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      clk: pxa: fix core frequency reporting unit

      Legacy drivers which are not yet ported, such as cpufreq-pxa[23]xx, rely
      on pxaXXx_get_clk_frequency_khz() to find the CPU core frequency.

      This reporting was broken because the expected unit is kHz and not
      Hz. Fix the reporting for pxa25x, pxa27x and pxa3xx.

      clk: rockchip: Fix PLL bandwidth

      In the TRM we see that BWADJ is "a 12-bit bus that selects the values
      1-4096 for the bandwidth divider (NB)":
       NB = BWADJ[11:0] + 1
      The recommended setting of NB: NB = NF / 2.

      So:
        NB = NF / 2
        BWADJ[11:0] + 1 = NF / 2
        BWADJ[11:0] = NF / 2 - 1

      Right now, we have:

      {                                               \
              .rate   = _rate##U,                     \
              .nr = _nr,                              \
              .nf = _nf,                              \
              .no = _no,                              \
              .bwadj = (_nf >> 1),                    \
      }

      That means we set bwadj to NF / 2, not NF / 2 - 1

      All of this is a bit confusing because we specify "NR" (the 1-based
      value), "NF" (the 1-based value), "NO" (the 1-based value), but
      "BWADJ" (the 0-based value) instead of "NB" (the 1-based value).

      Let's change to working with "NB" and fix the off by one error.  This
      may affect PLL jitter in a small way (hopefully for the better).

      clk: Allow providers to configure min/max rates

      clk providers are using the consumer APIs to set min/max rates on
      the clock they're providing. To encourage clk providers to move
      away from the consumer APIs, add a provider API to set the
      min/max rate of a clock. The assumption is that this is done
      before the clock can be requested via clk_get() and that the
      clock rate is already within the boundaries of the min/max that's
      configured.

      jbd2: avoid infinite loop when destroying aborted journal

      Commit 6f6a6fda2945 "jbd2: fix ocfs2 corrupt when updating journal
      superblock fails" changed jbd2_cleanup_journal_tail() to return EIO
      when the journal is aborted. That makes logic in
      jbd2_log_do_checkpoint() bail out which is fine, except that
      jbd2_journal_destroy() expects jbd2_log_do_checkpoint() to always make
      a progress in cleaning the journal. Without it jbd2_journal_destroy()
      just loops in an infinite loop.

      Fix jbd2_journal_destroy() to cleanup journal checkpoint lists of
      jbd2_log_do_checkpoint() fails with error.

      cpufreq: powernv: Report Psafe only if PMSR.psafe_mode_active bit is set

      On a reset cycle of OCC, although the system retires from safe
      frequency state the local pstate is not restored to Pmin or last
      requested pstate. Now if the cpufreq governor initiates a pstate
      change, the local pstate will be in Psafe and we will be reporting a
      false positive when we are not throttled.

      So in powernv_cpufreq_throttle_check() remove the condition which
      checks if local pstate is less than Pmin while checking for Psafe
      frequency. If the cpus are forced to Psafe then PMSR.psafe_mode_active
      bit will be set. So, when OCCs become active this bit will be cleared.
      Let us just rely on this bit for reporting throttling.

      cpufreq: powernv: Call throttle_check() on receiving OCC_THROTTLE

      Re-evaluate the chip's throttled state on recieving OCC_THROTTLE
      notification by executing *throttle_check() on any one of the cpu on
      the chip. This is a sanity check to verify if we were indeed
      throttled/unthrottled after receiving OCC_THROTTLE notification.

      We cannot call *throttle_check() directly from the notification
      handler because we could be handling chip1's notification in chip2. So
      initiate an smp_call to execute *throttle_check(). We are irq-disabled
      in the notification handler, so use a worker thread to smp_call
      throttle_check() on any of the cpu in the chipmask.

      cpufreq: powernv: Register for OCC related opal_message notification

      OCC is an On-Chip-Controller which takes care of power and thermal
      safety of the chip. During runtime due to power failure or
      overtemperature the OCC may throttle the frequencies of the CPUs to
      remain within the power budget.

      We want the cpufreq driver to be aware of such situations to be able
      to report the reason to the user. We register to opal_message_notifier
      to receive OCC messages from opal.

      powernv_cpufreq_throttle_check() reports any frequency throttling and
      this patch will report the reason or event that caused throttling. We
      can be throttled if OCC is reset or OCC limits Pmax due to power or
      thermal reasons. We are also notified of unthrottling after an OCC
      reset or if OCC restores Pmax on the chip.

      powerpc/powernv: Add definition of OPAL_MSG_OCC message type

      Add OPAL_MSG_OCC message definition to opal_message_type to receive
      OCC events like reset, load and throttled. Host performance can be
      affected when OCC is reset or OCC throttles the max Pstate.
      We can register to opal_message_notifier to receive OPAL_MSG_OCC type
      of message and report it to the userspace so as to keep the user
      informed about the reason for a performance drop in workloads.

      The reset and load OCC events are notified to kernel when FSP sends
      OCC_RESET and OCC_LOAD commands.  Both reset and load messages are
      sent to kernel on successful completion of reset and load operation
      respectively.

      The throttle OCC event indicates that the Pmax of the chip is reduced.
      The chip_id and throttle reason for reducing Pmax is also queued along
      with the message.

      cpufreq: powernv: Handle throttling due to Pmax capping at chip level

      The On-Chip-Controller(OCC) can throttle cpu frequency by reducing the
      max allowed frequency for that chip if the chip exceeds its power or
      temperature limits. As Pmax capping is a chip level condition report
      this throttling behavior at chip level and also do not set the global
      'throttled' on Pmax capping instead set the per-chip throttled
      variable. Report unthrottling if Pmax is restored after throttling.

      This patch adds a structure to store chip id and throttled state of
      the chip.

      cpufreq: Drop cpufreq_policy_restore()

      Notice that when cpufreq_policy_restore() is called, its per-CPU
      cpufreq_cpu_data variable has been already dereferenced and if that
      variable is not NULL, the policy local pointer in cpufreq_add_dev()
      contains its value.

      Therefore it is not necessary to dereference it again and the
      policy pointer can be used directly.  Moreover, if that pointer
      is not NULL, the policy is inactive (or the previous check would
      have made us return from cpufreq_add_dev()) so the restoration
      code from cpufreq_policy_restore() can be moved to that point
      in cpufreq_add_dev().

      Do that and drop cpufreq_policy_restore().

      drm/i915: Keep the mm.bound_list in rough LRU order

      When we shrink our working sets, we want to avoid stealing pages from
      objects that likely to be reused in the near future. We first look at
      inactive objects before processing active objects - but what about a
      recently active object that is about to be used again. That object's
      position in the bound_list is ordered by the time of binding, not the
      time of last use, so the most recently used inactive object could well
      be at the head of the shrink list. To compensate, give the object a bump
      to MRU when it becomes inactive (thus transitioning to the end of the
      first pass in shrink lists). Conversely, bumping on inactive makes
      bumping on active useless, since when we do have to reap from the active
      working set, everything is going to become inactive very quickly and the
      order pretty much random - just hope for the best at that point, as once
      we start stalling on active objects, we can hope that the rebinding
      neatly orders vital objects.

      arm64: spinlock: fix ll/sc unlock on big-endian systems

      When unlocking a spinlock, we perform a read-modify-write on the owner
      ticket in order to increment it and store it back with release
      semantics.

      In the LL/SC case, we load the 16-bit ticket using a 32-bit load and
      therefore store back the wrong halfword on a big-endian system,
      corrupting the lock after the first unlock and killing the system dead.

      This patch fixes the unlock code to use 16-bit accessors consistently.

      The current DTs were setting the cell size to 2, but used the default 
xlate
      function that was assuming an interrupt cell size of 1, leading to the
      second part of the cell (the flags) being ignored, while we were having an
      inconsistent binding between the interrupts and gpio (that could also be
      used as interrupts).

      That "binding" doesn't work either with newer SoCs that have multiple irq
      banks.

      Now that we fixed the pinctrl driver to handle this like it should always
      have been handled, convert the DT users, and while we're at it, remove the
      size-cells property of PIO that is completely useless.

      ARM: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      Otherwise, the GPIO range wouldn't be set at all unless the pin

      arm64: Use last level TLBI for user pte changes

      The flush_tlb_page() function is used on user address ranges when PTEs
      (or PMDs/PUDs for huge pages) were changed (attributes or clearing). For
      such cases, it is more efficient to invalidate only the last level of
      the TLB with the "tlbi vale1is" instruction.

      In the TLB shoot-down case, the TLB caching of the intermediate page
      table levels (pmd, pud, pgd) is handled by __flush_tlb_pgtable() via the
      __(pte|pmd|pud)_free_tlb() functions and it is not deferred to
      tlb_finish_mmu() (as of commit 285994a62c80 - "arm64: Invalidate the TLB
      corresponding to intermediate page table levels"). The tlb_flush()
      function only needs to invalidate the TLB for the last level of page
      tables; the __flush_tlb_range() function gains a fourth argument for
      last level TLBI.

      Currently create_mapping is marked with __ref, apparently because it

      ARM: mvebu: Warn about the wake-up sources not taken into account in 
suspend

      On the Armada 370/XP/38x/39x SoCs when the suspend to ram feature is
      supported, the SoCs are shutdown and will be woken up by an external
      micro-controller, so there is no possibility to setup wake-up sources
      from Linux. However, in standby mode, the SoCs stay powered and it is
      possible to wake-up from any interrupt sources. Since when the users
      configures the enabled wake-up sources there is no way to know if the
      user will be doing suspend to RAM or standby, we just allow all
      wake-up sources to be enabled, and only warn when entering suspend to
      RAM

      The purpose of this patch is to inform the user that in suspend to ram
      mode, the wake-up sources won't be taken into consideration.

      Intel integrated DMA (iDMA) 64-bit is a specific IP that is used as a 
part of
      LPSS devices such as HSUART or SPI. The iDMA IP is attached for private
      usage on each host controller independently.

      While it has similarities with Synopsys DesignWare DMA, the following
      distinctions doesn't allow to use the existing driver:
      - 64-bit mode with corresponding changes in Hardware Linked List data 
structure
      - many slight differences in the channel registers

      Moreover this driver is based on the DMA virtual channels framework that 
helps
      to make the driver cleaner and easy to understand.

      ACPI / PM: Attach ACPI power domain only once

      Some devices, like MFD subdevices, share a single ACPI companion device so
      that they are able to access their resources and children. However,
      currently all these subdevices are attached to the ACPI power domain and
      this might cause that the power methods for the companion device get 
called
      more than once.

      In order to solve this we attach the ACPI power domain only to the first
      physical device that is bound to the ACPI companion device. In case of MFD
      devices, this is the parent MFD device itself.

      PM / QoS: Make it possible to expose device latency tolerance to userspace

      Typically when a device is created the bus core it belongs to (for example
      PCI) does not know if the device supports things like latency tolerance.
      This is left to the driver that binds to the device in question. However,
      at that time the device has already been created and there is no way to 
set
      its dev->power.set_latency_tolerance anymore.

      So follow what has been done for other PM QoS attributes as well and allow
      drivers to expose and hide latency tolerance from userspace, if the device
      supports it.

      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed as most platforms don't use probing.
      There appears to be a great deal of blind copy and paste of this code.

      The GPIOD API can be used from boardcode, so that the DT check can be
      removed. To avoid breaking existing boardcode, _optional() variant has 
been
      chosen. For completely removing the DT check, the regulator has also been
      made optional, so that it could be supplied from boardcode.

      As a side-effect the patch fixes the after-probe reset GPIO state, so that
      the device is not kept in reset state.

      Now that minor LSMs can cleanly stack with major LSMs, remove the unneeded

      Yama CONFIG will allow it to work, regardless of the major LSM. Since

      libnvdimm: Add DSM support for Address Range Scrub commands

      Add support for the three ARS DSM commands:
      - Query ARS Capabilities - Queries the firmware to check if a given
        range supports scrub, and if so, which type (persistent vs. volatile)
      - Start ARS - Starts a scrub for a given range/type
      - Query ARS Status - Checks status of a previously started scrub, and
        provides the error logs if any.

        The commands are described by the example DSM spec at:
        http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf

      Also add these commands to the nfit_test test framework, and return

      clk: change clk_ops' ->determine_rate() prototype

      Clock rates are stored in an unsigned long field, but ->determine_rate()
      (which returns a rounded rate from a requested one) returns a long
      value (errors are reported using negative error codes), which can lead
      to long overflow if the clock rate exceed 2Ghz.

      Change ->determine_rate() prototype to return 0 or an error code, and pass
      a pointer to a clk_rate_request structure containing the expected target
      rate and the rate constraints imposed by clk users.

      The clk_rate_request structure might be extended in the future to contain
      other kind of constraints like the rounding policy, the maximum clock
      inaccuracy or other things that are not yet supported by the CCF
      (power consumption constraints ?).

      ====================
      net/mlx4_en: Hardware accelerated 802.1ad

      This patchset by Hadar introduces support in Hardware accelerated 
802.1ad, for
      ConnectX-3pro NIC's.  In order to support existing deployment, and due to 
some
      hardware limitations, the feature is disabled by default, and needed to be
      enabled using a private flag in ethtool. Ofcourse user can enable the 
private
      flag only if hardware has support.
      After being enabled, the standard ethtool -k/-K can be used.

      Patchset was applied and tested over commit 71790a2 ("hv_netvsc: Add 
structs
      and handlers for VF messages")

      net/mlx4_en: Add support for hardware accelerated 802.1ad vlan

      To enable device support in accelerated 802.1ad vlan, the port
      capability "packet has vlan enable" (phv_en) should be set.
      Firmware won't work properly, in case phv_en is not set.

      The user can enable "phv_en" port capability with the new ethtool
      private flag phv-bit. The phv-bit private flag default value is OFF,
      users who are interested in 802.1ad hardware acceleration should turn ON
      the phv-bit private flag:
      $ ethtool --set-priv-flags eth1 phv-bit on

      Once the private flag is set, the device is ready for 802.1ad vlan
      acceleration.

      The user should also change the interface device features and turn on
      "tx-vlan-stag-hw-insert" which is off by default:
      $ ethtool -K eth1  tx-vlan-stag-hw-insert on

      "phv-bit" private flag setting is available only for Physical
      Functions(PF), the Virtual Function (VF) will be able to use the feature
      by setting "tx-vlan-stag-hw-insert" ethtool device feature only if the
      feature was enabled by the Hypervisor.

      device.

      To allow 802.1ad accelerated device, "packet has vlan" (phv)
      Firmware capability should be available. Firmware without the
      phv capability won't behave properly and can't support 802.1ad device

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      New features:

        - Introduce PERF_RECORD_SWITCH(_CPU_WIDE) and use it in 'record' to
          ask for context switches, allowing non priviledged tasks to know
          when they are switched in and out, which wasn't possible with
          the other context switch tracepoint and software events, see the
          patch description for a comprehensive justification (Adrian Hunter)

        - Stop collecting /proc/kallsyms in perf.data files, saving about
          4.5MB on a typical x86-64 system, use the the symbol resolution
          routines used in all the other tools (report, top, etc) now that
          we can ask libtraceevent to use perf's symbol resolution code.
          (Arnaldo Carvalho de Melo)

      User visible fixes:

        - Expose perf's symbol resolver to libtraceevent, so that its plugins 
can
          resolve tracepoint fields to kernel functions, like the 'function' 
field
          in the "timer:hrtimer_start tracepoint" (Arnaldo Carvalho de Melo)

      Infrastructure changes:

        - Map propagation of thread and cpu maps improvements, prep work for
          'perf stat' new features (Jiri Olsa)

      gpio: etraxfs: add support for ARTPEC-3

      Add support for the GIO block in the ARTPEC-3 SoC.  The basic
      functionality is essentialy the same as the version in the ETRAX FS,
      except for a different set of ports, including a read-only port.

      gpio: etraxfs: fix set register flag

      BGPIO_F_UNREADABLE_REG_SET is incorrect, since the set register _is_
      readable.  What's really required is BGPIO_F_READ_OUTPUT_REG_SET:

      pinctrl: sunxi: Add custom irq_domain_ops

      The current interrupt parsing code was working by accident, because the
      default was actually parsing the first node of interrupts.

      While that was mostly working (and the flags were actually ignored), this
      binding has never been documented, and doesn't work with SoCs that have
      multiple interrupt banks anyway.

      Add a proper interrupt xlate function, that uses the same description than
      the GPIOs (<bank> <pin> <flags>), that will make things less confusing.

      The EINT number will still be used as the hwirq number, but won't be
      exposed through the DT.

      There is mostly one evolution on the dma side, to enable cooperation

      Once all drivers using DMA are converted, the legacy DMA API should

      gpio: omap: use raw locks for locking

      This patch converts gpio_bank.lock from a spin_lock into a
      raw_spin_lock. The call path is to access this lock is always under a
      raw_spin_lock, for instance
      - __setup_irq() holds &desc->lock with irq off
        + __irq_set_trigger()
         + omap_gpio_irq_type()

      - handle_level_irq() (runs with irqs off therefore raw locks)
        + mask_ack_irq()
         + omap_gpio_mask_irq()

      This fixes the obvious backtrace on -RT. However the locking vs context
      is not and this is not limited to -RT:
      - omap_gpio_irq_type() is called with IRQ off and has an conditional
        call to pm_runtime_get_sync() which may sleep. Either it may happen or
        it may not happen but pm_runtime_get_sync() should not be called with
        irqs off.

      - omap_gpio_debounce() is holding the lock with IRQs off.
        + omap2_set_gpio_debounce()
         + clk_prepare_enable()
          + clk_prepare() this one might sleep.
        The number of users of gpiod_set_debounce() / gpio_set_debounce()
        looks low but still this is not good.

      tile: Provide atomic_{or,xor,and}

      Implement atomic logic ops -- atomic_{or,xor,and}.

      For tilegx, these are relatively straightforward; the architecture
      provides atomic "or" and "and", both 32-bit and 64-bit.  To support
      xor we provide a loop using "cmpexch".

      For the older 32-bit tilepro architecture, we have to extend
      the set of low-level assembly routines to include 32-bit "and",
      as well as all three 64-bit routines.  Somewhat confusingly,
      some 32-bit versions are already used by the bitops inlines, with
      parameter types appropriate for bitops, so we have to do a bit of
      casting to match "int" to "unsigned long".

      frv: Rewrite atomic implementation

      Mostly complete rewrite of the FRV atomic implementation, instead of
      using assembly files, use inline assembler.

      The out-of-line CONFIG option makes a bit of a mess of things, but a
      little CPP trickery gets that done too.

      FRV already had the atomic logic ops but under a non standard name,
      the reimplementation provides the generic names and provides the
      intermediate form required for the bitops implementation.

      The slightly inconsistent __atomic32_fetch_##op naming is because
      __atomic_fetch_##op conlicts with GCC builtin functions.

      The 64bit atomic ops use the inline assembly %Ln construct to access
      the low word register (r+1), afaik this construct was not previously
      used in the kernel and is completely undocumented, but I found it in
      the FRV GCC code and it seems to work.

      FRV had a non-standard definition of atomic_{clear,set}_mask() which
      would work types other than atomic_t, the one user relying on that
      (arch/frv/kernel/dma.c) got converted to use the new intermediate
      form.

      pinctrl: sunxi: Use common functions to change irq_chip and handler

      The current code uses some custom variable affectations, while we have
      common functions to do exactly that. Move to the common functions.

      arm64/BUG: Show explicit backtrace for WARNs

      The generic slowpath WARN implementation prints a backtrace, but
      the report_bug() based implementation does not, opting to print the
      registers instead which is generally not as useful.

      Ideally, report_bug() should be fixed to make the behaviour more
      consistent, but in the meantime this patch generates a backtrace
      directly from the arm64 backend instead so that this functionality
      is not lost with the migration to report_bug().

      As a side-effect, the backtrace will be outside the oops end
      marker, but that's hard to avoid without modifying generic code.

      This patch can go away if report_bug() grows the ability in the
      future to generate a backtrace directly or call an arch hook at the
      appropriate time.

      arm64/BUG: Use BRK instruction for generic BUG traps

      Currently, the minimal default BUG() implementation from asm-
      generic is used for arm64.

      This patch uses the BRK software breakpoint instruction to generate
      a trap instead, similarly to most other arches, with the generic
      BUG code generating the dmesg boilerplate.

      This allows bug metadata to be moved to a separate table and
      reduces the amount of inline code at BUG and WARN sites.  This also
      avoids clobbering any registers before they can be dumped.

      To mitigate the size of the bug table further, this patch makes
      use of the existing infrastructure for encoding addresses within
      the bug table as 32-bit offsets instead of absolute pointers.
      (Note that this limits the kernel size to 2GB.)

      Traps are registered at arch_initcall time for aarch64, but BUG
      has minimal real dependencies and it is desirable to be able to
      generate bug splats as early as possible.  This patch redirects
      all debug exceptions caused by BRK directly to bug_handler() until
      the full debug exception support has been initialised.

      arm64/debug: Simplify BRK insn opcode declarations

      The way the KGDB_DYN_BRK_INS_BYTEx macros are declared is more
      complex than it needs to be.  Also, the macros are only used in one
      place, which is arch-specific anyway.

      This patch refactors the macros to simplify them, and exposes an
      argument so that we can have a single macro instead of 4.

      As a side effect, this patch also fixes some anomalous spellings of
      "KGDB".

      These changes alter the compile types of some integer constants
      that are harmless but trigger truncation warnings in gcc when
      assigning to 32-bit variables.  This patch adds an explicit cast
      for the affected cases.

      arm64: Generalise msr_s/mrs_s operations

      The system register encoding generated by sys_reg() works only
      for MRS/MSR(Register) operations, as we hardcode Bit20 to 1 in
      mrs_s/msr_s mask. This makes it unusable for generating instructions
      accessing registers with Op0 < 2(e.g, PSTATE.x with Op0=0).

      As per ARMv8 ARM, (Ref: ARMv8 ARM, Section: "System instruction class
      encoding overview", C5.2, version:ARM DDI 0487A.f), the instruction
      encoding reserves bits [20-19] for Op0.

      arm64: kernel: Add optional CONFIG_ parameter to ALTERNATIVE()

      Some uses of ALTERNATIVE() may depend on a feature that is disabled at
      compile time by a Kconfig option. In this case the unused alternative
      instructions waste space, and if the original instruction is a nop, it
      wastes time and space.

      This patch adds an optional 'config' option to ALTERNATIVE() and
      alternative_insn that allows the compiler to remove both the original
      and alternative instructions if the config option is not defined.

      arm64: kernel: Add min_field_value and use '>=' for feature detection

      When a new cpu feature is available, the cpu feature bits will have some
      initial value, which is incremented when the feature is updated.
      This patch changes 'register_value' to be 'min_field_value', and checks
      the feature bits value (interpreted as a signed int) is greater than this
      minimum.

      arm64: alternative: Provide if/else/endif assembler macros

      The existing alternative_insn macro has some limitations that make it
      hard to work with. In particular the fact it takes instructions from it
      own macro arguments means it doesn't play very nicely with C pre-processor
      macros because the macro arguments look like a string to the C
      pre-processor. Workarounds are (probably) possible but things start to
      look ugly.

      Introduce an alternative set of macros that allows instructions to be
      presented to the assembler as normal and switch everything over to the
      new macros.

      arm64: perf: condense event number maps

      Most of the cache events an architecture might support do not map well
      to those provided by the ARM architecture, and as such most entries in
      the event number maps are *_UNSUPPORTED. Unfortuantely as 0 is a valid
      physical event identifier, the *_UNSUPPORTED macros expand to a non-zero
      value and thus each unsupported event must be explicitly initialised as
      such. This leads to large diffs when adding support for a new CPU, and
      makes it difficult to spot the important information.

      This patch follows arch/arm/ in making use of PERF_*_ALL_UNSUPPORTED
      macros to initialise all entries to *_UNSUPPORTED before overriding this
      for the specific events we actually support, resulting in a significant
      source code reduction.

      arm64: dma-mapping: implement dma_get_sgtable()

      The default dma_common_get_sgtable() implementation relies on the CPU
      address of the buffer being a regular lowmem address. This is not always
      the case on arm64, since allocations from the various DMA pools may have
      remapped vmalloc addresses, rendering the use of virt_to_page() invalid.

      Fix this by providing our own implementation based on the fact that we
      can safely derive a physical address from the DMA address in both cases.

      arm64: Better native ptrace support for compat tasks

      The compat ptrace interface allows access to the TLS register, hardware
      breakpoints and watchpoints, syscall number. However, a native task
      using the native ptrace interface to debug compat tasks (e.g. multi-arch
      gdb) only has access to the general and VFP register sets. The compat
      ptrace interface cannot be accessed from a native task.

      This patch adds a new user_aarch32_ptrace_view which contains the TLS,
      hardware breakpoint/watchpoint and syscall number regsets in addition to
      the existing GPR and VFP regsets. This view is backwards compatible with
      the previous kernels. Core dumping of 32-bit tasks and compat ptrace are
      not affected since the original user_aarch32_view is preserved.

      arm64: Add support for hardware updates of the access and dirty pte bits

      The ARMv8.1 architecture extensions introduce support for hardware
      updates of the access and dirty information in page table entries. With
      TCR_EL1.HA enabled, when the CPU accesses an address with the PTE_AF bit
      cleared in the page table, instead of raising an access flag fault the
      CPU sets the actual page table entry bit. To ensure that kernel
      modifications to the page tables do not inadvertently revert a change
      introduced by hardware updates, the exclusive monitor (ldxr/stxr) is
      adopted in the pte accessors.

      When TCR_EL1.HD is enabled, a write access to a memory location with the
      DBM (Dirty Bit Management) bit set in the corresponding pte
      automatically clears the read-only bit (AP[2]). Such DBM bit maps onto
      the Linux PTE_WRITE bit and to check whether a writable (DBM set) page
      is dirty, the kernel tests the PTE_RDONLY bit. In order to allow
      read-only and dirty pages, the kernel needs to preserve the software
      dirty bit. The hardware dirty status is transferred to the software
      dirty bit in ptep_set_wrprotect() (using load/store exclusive loop) and
      pte_modify().

      arm64: perf: replace arch_find_n_match_cpu_physical_id with 
of_cpu_device_node_get

      arch_find_n_match_cpu_physical_id parses the device tree to get the
      device node for a given logical cpu index. However, since ARM PMUs get
      probed after the CPU device nodes are stashed while registering the
      cpus, we can use of_cpu_device_node_get to avoid another DT parse.

      This patch replaces arch_find_n_match_cpu_physical_id with
      of_cpu_device_node_get to reuse the stashed value directly instead.

      pinctrl: driver for Conexant Digicolor CX92755 pin mapping

      This adds pinctrl and gpio driver to the CX92755 SoC "General
      Purpose Pin Mapping" hardware block. The CX92755 is one SoC
      from the Conexant Digicolor series. Pin mapping hardware supports
      configuring pins as either GPIO, or up to 3 other "client select"
      functions. This driver adds support for pin muxing using the
      generic device tree binding, and a basic gpiolib driver for
      the GPIO functionality.

      This driver does not currently support GPIO interrupts, and
      pad configuration.

      v2:
      * Address review comments for Linus Walleij:
        - Add a pointer to pinctrl_desc in struct dc_pinmap
        - Drop the now redundant pinctrl_pin_desc field
        - Adapt dc_get_group_{name,pins} to these changes, and
          add a comment explaining the 1-to-1 pin-groups relation

      drm/i915: kerneldoc for tiling IOCTL and swizzle functions

      Chris rightfully suggested that documenting fences without documenting
      the BO tiling tracking doesn't make much sense, so fix that.

      The important bit to stress here (since it lead to some confusion) is
      the GEM doesn't really care about tiling. Except for a few select cases
      where the kernel needs to manage something that userspace can't take
      care of: Namely the limited number of fences and fixing up swizzling,
      although we still fail at the later.

      v2: Move the low-level tiling/swizzling functions and kerneldoc to
      i915_gem_fence.c and leave only the userspace interface here.
      Suggested by Chris.

      tcp: tso: allow deferring under reordering state

      While doing experiments with reordering resilience, we found

      This patch removes the limitation, as we did for CWR state

      tcp_tso_should_defer()")

      Neal Cardwell had a concern about limited transmit so
      Yuchung conducted experiments on GFE and found nothing
      worth adding an extra check on fast path :

        if (icsk->icsk_ca_state == TCP_CA_Disorder &&
            tcp_sk(sk)->reordering == sysctl_tcp_reordering)

      ravb: minimize TX data copying

      Renesas Ethernet AVB controller requires that all data are aligned on 
4-byte
      boundary.  While it's  easily achievable for  the RX  data with  the help 
of
      skb_reserve() (we even align on 128-byte boundary as recommended by the 
manual),
      we  can't  do the same with the TX data, and it always comes  unaligned 
from
      the networking core. Originally we solved it an easy way, copying all 
packet
      to  a  preallocated  aligned buffer; however, it's enough to copy only up 
to
      3 first bytes from each packet, doing the transfer using 2 TX descriptors
      instead of just 1. Here's an implementation of the new  TX algorithm that
      significantly reduces the driver's memory requirements.

      net/mlx5e: TX latency optimization to save DMA reads

      A regular TX WQE execution involves two or more DMA reads -
      one to fetch the WQE, and another one per WQE gather entry.

      These DMA reads obviously increase the TX latency.
      There are two mlx5 mechanisms to bypass these DMA reads:
      1) Inline WQE
      2) Blue Flame (BF)

      An inline WQE contains a whole packet, thus saves the DMA read/s
      of the regular WQE gather entry/s. Inline WQE support was already
      added in the previous commit.

      A BF WQE is written directly to the device I/O mapped memory, thus
      enables saving the DMA read that fetches the WQE.

      The BF WQE I/O write must be in cache line granularity, thus uses
      the CPU write combining mechanism.
      A BF WQE I/O write acts also as a TX doorbell for notifying the
      device of new TX WQEs.
      A BF WQE is written to the same I/O mapped address as the regular TX
      doorbell, thus this address is being mapped twice - once by ioremap()
      and once by io_mapping_map_wc().

      While both mechanisms reduce the TX latency, they both consume more CPU
      cycles than a regular WQE:
      - A BF WQE must still be written to host memory, in addition to being
        written directly to the device I/O mapped memory.
      - An inline WQE involves copying the SKB data into it.

      To handle this tradeoff, we introduce here a heuristic algorithm that
      strives to avoid using these two mechanisms in case the TX queue is
      being back-pressured by the device, and limit their usage rate otherwise.

      An inline WQE will always be "Blue Flamed" (written directly to the
      device I/O mapped memory) while a BF WQE may not be inlined (may contain
      gather entries).

      Preliminary testing using netperf UDP_RR shows that the latency goes down
      from 17.5us to 16.9us, while the message rate (tested with pktgen) stays
      the same.

      irqchip/bcm7120-l2: Fix interrupt status for multiple parent IRQs

      Our irq-bcm7120-l2 interrupt controller driver utilizes the same handler
      function for the different parent interrupts it services: UPG_MAIN, 
UPG_BSC for
      instance.

      The problem is that function reads the IRQSTAT register which can combine
      interrupt causes for different parent interrupts, such that we can end-up 
in
      the following situation:

      - CPU takes an interrupt
      - bcm7120_l2_intc_irq_handle() reads IRQSTAT
      - generic_handle_irq() is invoked
      - there are still pending interrupts flagged in IRQSTAT from a different 
parent
      - handle_bad_irq() is invoked for these since they come from a different 
irq_desc/irq

      In order to fix this, make sure that we always mask IRQSTAT with the
      appropriate bits that correspond go the parent interrupt source this is 
coming
      from. To simplify things, associate an unique structure per parent 
interrupt
      handler to avoid multiplying the number of lookups.

      irqchip/bcm7120-l2: Perform suspend/resume even without installed child 
IRQs

      Make use of the new irq_chip_generic suspend/resume callbacks.

      This is required because if there are no installed child IRQs for this
      chip, the irq_chip::irq_{suspend,resume} functions will not be called.
      However, we still need to save/restore the forwarding mask, to enable
      the top-level GIC interrupt; otherwise, we lose UART output after S3
      resume.

      In addition to refactoring the callbacks, we have to self-initialize the
      mask cache, since the genirq core also doesn't initialize this until the
      first child IRQ is installed.

      The original problem report is described in extra detail here:

      genirq: Add chip_[suspend|resume] PM support to irq_chip

      Some (admittedly odd) irqchips perform functions that are not directly
      related to any of their child IRQ lines, and therefore need to perform
      some tasks during suspend/resume regardless of whether there are
      any "installed" interrupts for the irqchip. However, the current
      generic-chip framework does not call the chip's irq_{suspend,resume}
      when there are no interrupts installed (this makes sense, because there
      are no irq_data objects for such a call to be made).

      More specifically, irq-bcm7120-l2 configures both a forwarding mask
      (which affects other top-level GIC IRQs) and a second-level interrupt
      mask (for managing its own child interrupts). The former must be
      saved/restored on suspend/resume, even when there's nothing to do for
      the latter.

      This patch adds a new set of suspend/resume hooks to irq_chip_generic,
      to help represent *chip* suspend/resume, rather than IRQ suspend/resume.
      These callbacks will always be called for an IRQ chip (regardless of the
      installed interrupts) and are based on the per-chip irq_chip_generic
      struct, rather than the per-IRQ irq_data struct.

      The original problem report is described in extra detail here:

      irqchip: Appropriate __init annotation for const data

      Init data marked const should be annotated with __initconst for
      correctness and not __initdata.  And for those already __initconst,
      they should be qualified as const at the compiler level too.
      This also fixes LTO builds that otherwise fail with section mismatch
      errors.

      Now that the GIC chip implementation enables IRQCHIP_SKIP_SET_WAKE and
      IRQCHIP_MASK_ON_SUSPEND by default, the platforms requiring them need
      not override the irqchip flags as before.

      irqchip/gic: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND

      The GIC controller doesn't provides any facility to configure the wakeup
      sources. For the same reason, GIC chip implementation can't provide
      irq_set_wake functionality, but that results in the irqchip core
      preventing the systems from entering sleep states like "suspend to RAM".

      The GICv1/v2 controllers support wakeup events. They signal these wakeup
      events even when CPU interface is disabled which means the wakeup
      outputs are always enabled with the required logic in always-on domain.
      An implementation can powerdown the GIC completely, but then the wake-up
      must be relayed to some control logic within the power controller that
      acts as wake-up interrupt controller.

      Setting the IRQCHIP_SKIP_SET_WAKE flags will ensure that the interrupts
      from GIC can work as wakeup interrupts and resume from suspend-to-{idle,
      ram}. The wakeup interrupt sources need to use enable_irq_wake() and the
      irqchip core will then set the IRQD_WAKEUP_STATE flag.

      Also it's always safer to mask all the non wakeup interrupts are masked
      at the chip level when suspending. The irqchip infrastructure can handle
      masking of those interrupts at the chip level. The chip implementation
      just have to indicate that with IRQCHIP_MASK_ON_SUSPEND.

      This patch enables IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so
      that the irqchip core allows and handles the power managemant wake up
      modes.

      net: bcmgenet: Register link_update callback for all MoCA PHYs

      Commit 8d88c6ebb34c ("net: bcmgenet: enable MoCA link state change
      detection") added a fixed PHY link_update callback for MoCA PHYs when
      registered using platform_data exclusively, this change is also
      applicable to systems using Device Tree as their primary configuration
      interface.

      In order for this to work, move the link_update assignment into
      bcmgenet_moca_phy_setup() where we know for sure that we are running on
      a MoCA GENET instance, and do not override phydev->link since this is:

      - properly taken care of by the PHY library by getting the link UP/DOWN
        interrupts
      - this now runs everytime we call bcmgenet_open(), so we need to
        preserve whatever we detected before we went administratively DOWN and
        then UP
      - we need to make sure that MoCA PHYs start with a link DOWN during
        probe in order to force a link transition to occur

      To avoid a forward declaration, move bcmgenet_fixed_phy_link_update()
      above its caller.

      net: bcmgenet: Remove checks on clock handles

      Instead of multiplying the number of checks for IS_ERR(priv->clk),
      simply NULLify the 'struct clk' pointer which is something the Linux
      common clock framework perfectly deals with and does early return for
      each and every single clk_* API functions.

      Having every single function check for !IS_ERR(priv->clk) is both
      redundant and error prone, as it turns out, we were doing it for the
      main GENET clock: priv->clk, but not for the Wake-on-LAN or EEE clock,
      so let's just be consistent here.

making

      sub-channel offers in flight are properly handled.

      tipc: clean up socket layer message reception

      When a message is received in a socket, one of the call chains
      tipc_sk_rcv()->tipc_sk_enqueue()->filter_rcv()(->tipc_sk_proto_rcv())
      or
      tipc_sk_backlog_rcv()->filter_rcv()(->tipc_sk_proto_rcv())
      are followed. At each of these levels we may encounter situations
      where the message may need to be rejected, or a new message
      produced for transfer back to the sender. Despite recent
      improvements, the current code for doing this is perceived
      as awkward and hard to follow.

      Leveraging the two previous commits in this series, we now
      introduce a more uniform handling of such situations. We
      let each of the functions in the chain itself produce/reverse
      the message to be returned to the sender, but also perform the
      actual forwarding. This simplifies the necessary logics within
      each function.

      tipc: introduce new tipc_sk_respond() function

      Currently, we use the code sequence

      if (msg_reverse())
         tipc_link_xmit_skb()

      at numerous locations in socket.c. The preparation of arguments
      for these calls, as well as the sequence itself, makes the code
      unecessarily complex.

      In this commit, we introduce a new function, tipc_sk_respond(),
      that performs this call combination. We also replace some, but not
      yet all, of these explicit call sequences with calls to the new
      function. Notably, we let the function tipc_sk_proto_rcv() use
      the new function to directly send out PROBE_REPLY messages,
      instead of deferring this to the calling tipc_sk_rcv() function,
      as we do now.

      tipc: let function tipc_msg_reverse() expand header when needed

      The shortest TIPC message header, for cluster local CONNECTED messages,
      is 24 bytes long. With this format, the fields "dest_node" and
      "orig_node" are optimized away, since they in reality are redundant
      in this particular case.

      However, the absence of these fields leads to code inconsistencies
      that are difficult to handle in some cases, especially when we need
      to reverse or reject messages at the socket layer.

      In this commit, we concentrate the handling of the absent fields
      to one place, by letting the function tipc_msg_reverse() reallocate
      the buffer and expand the header to 32 bytes when necessary. This
      means that the socket code now can assume that the two previously
      absent fields are present in the header when a message needs to be
      rejected. This opens up for some further simplifications of the
      socket code.

      intel_idle: allow idle states to be freeze-mode specific

      intel_idle uses a NULL "enter" field in a cpuidle state
      to recognize the invalid entry terminating a variable-length array.

      Linux-4.0 added support for the system-wide "freeze" state
      in cpuidle drivers via the new "enter_freeze" field.

      The natural way to expose a deep idle state for freeze,
      but not for run-time idle is to supply "enter_freeze" without "enter";
      so we update the driver to accept such states.

      ARM: mvebu: Add standby support

      Until now only one Armada XP and one Armada 388 based board supported
      suspend to ram. However, most of the recent mvebu SoCs can support the
      standby mode. Unlike for the suspend to ram, nothing special has to be
      done for these SoCs. This patch allows the system to use the standby
      mode on Armada 370, 38x, 39x and XP SoCs. There are issues with the
      Armada 375, and the support might be added (if possible) in a future
      patch.

      ARM: mvebu: prepare pm-board.c for the introduction of Armada 38x support

      The pm-board.c code contains the board-specific logic to enter suspend
      to RAM. Until now, the code supported only the Armada XP GP board, so
      all functions and symbols were named with armada_xp_gp. However, it
      turns out that the Armada 388 GP also uses the same 3 GPIOs protocol
      to talk to the PIC microcontroller that controls the power supply.

      Since we are going to re-use the same code with no change for Armada
      38x, this commit renames the functions and symbols to use just
      "armada" instead of "armada_xp_gp". Better names can be found if one
      day other boards having a different protocol/mechanism are supported
      in the kernel.

      Add an extension to the heavy barrier code to allow a SoC specific

      ARM: move heavy barrier support out of line

      The existing memory barrier macro causes a significant amount of code
      to be inserted inline at every call site.  For example, in
      gpio_set_irq_type(), we have this for mb():

      c0344c08:       f57ff04e        dsb     st
      c0344c0c:       e59f8190        ldr     r8, [pc, #400]  ; c0344da4 
<gpio_set_irq_type+0x230>
      c0344c10:       e3590004        cmp     r9, #4
      c0344c14:       e5983014        ldr     r3, [r8, #20]
      c0344c18:       0a000054        beq     c0344d70 <gpio_set_irq_type+0x1fc>
      c0344c1c:       e3530000        cmp     r3, #0
      c0344c20:       0a000004        beq     c0344c38 <gpio_set_irq_type+0xc4>
      c0344c24:       e50b2030        str     r2, [fp, #-48]  ; 0xffffffd0
      c0344c28:       e50bc034        str     ip, [fp, #-52]  ; 0xffffffcc
      c0344c2c:       e12fff33        blx     r3
      c0344c30:       e51bc034        ldr     ip, [fp, #-52]  ; 0xffffffcc
      c0344c34:       e51b2030        ldr     r2, [fp, #-48]  ; 0xffffffd0
      c0344c38:       e5963004        ldr     r3, [r6, #4]

      Moving the outer_cache_sync() call out of line reduces the impact of
      the barrier:

      c0344968:       f57ff04e        dsb     st
      c034496c:       e35a0004        cmp     sl, #4
      c0344970:       e50b2030        str     r2, [fp, #-48]  ; 0xffffffd0
      c0344974:       0a000044        beq     c0344a8c <gpio_set_irq_type+0x1b8>
      c0344978:       ebf363dd        bl      c001d8f4 <arm_heavy_mb>
      c034497c:       e5953004        ldr     r3, [r5, #4]

      This should reduce the cache footprint of this code.  Overall, this
      results in a reduction of around 20K in the kernel size:

          text    data      bss      dec     hex filename
      10773970  667392 10369656 21811018 14ccf4a ../build/imx6/vmlinux-old
      10754219  667392 10369656 21791267 14c8223 ../build/imx6/vmlinux-new

      Another advantage to this approach is that we can finally resolve the
      issue of SoCs which have their own memory barrier requirements within
      multiplatform kernels (such as OMAP.)  Here, the bus interconnects
      need additional handling to ensure that writes become visible in the
      correct order (eg, between dma_map() operations, writes to DMA
      coherent memory, and MMIO accesses.)

      phy-sun4i-usb: Add support for monitoring vbus via a power-supply

      On some boards there is no vbus_det gpio pin, instead vbus-detection for
      otg can be done via the pmic.

      This commit adds support for monitoring vbus_det via the power_supply
      exported by the pmic, enabling support for otg on these boards.

      phy-sun4i-usb: Add support for boards with broken Vusb-detection

      On some boards we cannot detect the presence of an external Vusb, because
      e.g. the 5V of the otg connector is directly connected to the 5V of the 
board,
      and thus is always high.

      This commit adds support for using such boards by only looking at the
      id-detection pin.

      phy-sun4i-usb: Swap check for disconnect threshold

      Before this commit the code for determining the disconnect threshold was
      checking for "allwinner,sun4i-a10-usb-phy" or 
"allwinner,sun6i-a31-usb-phy"
      assuming that those where the exception and then newer SoCs would use a
      disconnect threshold of 2 like sun7i does. But it turns out that newer
      SoCs use a disconnect threshold of 3 and sun5i and sun7i are the
      exceptions, so check for those instead.

      Here are the settings from the various Allwinner SDK sources:
       sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
       sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
       sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun8i-h3:  USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);

      Note this commit makes no functional changes as currently we only support
      sun4i - sun7i.

      Intel Wired LAN Driver Updates 2015-07-23

      This series contains updates to e1000e, igb, ixgbevf, i40e and i40evf.

      Emil extends the reporting of the RSS key and hash table by adding support
      for x550 VFs.

      Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a
      call to pm_qos_remove_request() to cleanup the QoS request made in
      e1000_open().

      Todd updates igb to report unsupported for ethtool coalesce settings
      that are not supported.  Also updated the driver to use the ARRAY_SIZE()
      macro.

      Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf
      which would never change dynamically.  So update the switch() statement
      to have a default case and switch on "new_latency_range" versus the
      current ITR setting.

      Shannon cleans up i40e code, where there were un-needed goto's.  Also
      clean up error status messages that were causing some confusion in
      PHY and FCoE setup error reports.

      Mitch updates the virtual channel interface to prepare for the x722 device
      and other future devices, so that the VF driver can report what its
      capable of supporting to the PF driver.  Updates the i40evf driver to
      handle resets like Core or EMP resets, where the device is reinitialized
      and the VF will not get the same VSI.

      Jesse updates the i40e and i40evf driver to use the kernel BIT() and
      BIT_ULL() macros.

      cpufreq: Remove cpufreq_rwsem

      cpufreq_rwsem was introduced in commit 6eed9404ab3c4 ("cpufreq: Use
      rwsem for protecting critical sections) in order to replace
      try_module_get() on the cpu-freq driver. That try_module_get() worked
      well until the refcount was so heavily used that module removal became
      more or less impossible.

      Though when looking at the various (undocumented) protection
      mechanisms in that code, the randomly sprinkeled around cpufreq_rwsem
      locking sites are superfluous.

      The policy, which is acquired in cpufreq_cpu_get() and released in
      cpufreq_cpu_put() is sufficiently protected already.

        cpufreq_cpu_get(cpu)
          /* Protects against concurrent driver removal */
          read_lock_irqsave(&cpufreq_driver_lock, flags);
          policy = per_cpu(cpufreq_cpu_data, cpu);
          kobject_get(&policy->kobj);
          read_unlock_irqrestore(&cpufreq_driver_lock, flags);

      The reference on the policy serializes versus module unload already:

        cpufreq_unregister_driver()
          subsys_interface_unregister()
            __cpufreq_remove_dev_finish()
              per_cpu(cpufreq_cpu_data) = NULL;
        cpufreq_policy_put_kobj()

      If there is a reference held on the policy, i.e. obtained prior to the
      unregister call, then cpufreq_policy_put_kobj() will wait until that
      reference is dropped. So once subsys_interface_unregister() returns
      there is no policy pointer in flight and no new reference can be
      obtained. So that rwsem protection is useless.

      The other usage of cpufreq_rwsem in show()/store() of the sysfs
      interface is redundant as well because sysfs already does the proper
      kobject_get()/put() pairs.

      That leaves CPU hotplug versus module removal. The current
      down_write() around the write_lock() in cpufreq_unregister_driver() is
      silly at best as it protects actually nothing.

      The trivial solution to this is to prevent hotplug across
      cpufreq_unregister_driver completely.

      toshiba_acpi: Add /dev/toshiba_acpi device

      There were previous attempts to "merge" the toshiba SMM module to the
      toshiba_acpi one, they were trying to imitate what the old toshiba
      module does, however, some models (TOS1900 devices) come with a
      "crippled" implementation and do not provide all the "features" a
      "genuine" Toshiba BIOS does.

      This patch adds a new device called toshiba_acpi, which aim is to
      enable userspace to access the SMM on Toshiba laptops via ACPI calls.

      Creating a new convenience _IOWR command to access the SCI functions
      by opening/closing the SCI internally to avoid buggy BIOS, while at
      the same time providing backwards compatibility.

      Older programs (and new) who wish to access the SMM on newer models
      can do it by pointing their path to /dev/toshiba_acpi (instead of
      /dev/toshiba) as the toshiba.h header was modified to reflect these
      changes as well as adds all the toshiba_acpi paths and command,
      however, it is strongly recommended to use the new IOCTL for any
      SCI command to avoid any buggy BIOS.

      Staging: most: add MOST driver's core module

      This patch adds the core module of the MOST driver to the kernel's driver
      staging area. This module is part of the MOST driver and handles the
      configuration interface in sysfs, the buffer management and the data
      routing.

      MOST defines the protocol, hardware and software layers necessary to allow
      for the efficient and low-cost transport of control, real-time and packet
      data using a single medium (physical layer). Media currently in use are
      fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST
      also supports various speed grades up to 150 Mbps.
      For more information on MOST, visit the MOST Cooperation website:
      www.mostcooperation.com.

      Cars continue to evolve into sophisticated consumer electronics platforms,
      increasing the demand for reliable and simple solutions to support audio,
      video and data communications. MOST can be used to connect multiple
      consumer devices via optical or electrical physical layers directly to one
      another or in a network configuration. As a synchronous network, MOST
      provides excellent Quality of Service and seamless connectivity for
      audio/video streaming. Therefore, the driver perfectly fits to the mission
      of Automotive Grade Linux to create open source software solutions for
      automotive applications.

      The driver consists basically of three layers. The hardware layer, the
      core layer and the application layer. The core layer consists of the core
      module only. This module handles the communication flow through all three
      layers, the configuration of the driver, the configuration interface
      representation in sysfs, and the buffer management.
      For each of the other two layers a selection of modules is provided. These
      modules can arbitrarily be combined to meet the needs of the desired
      system architecture. A module of the hardware layer is referred to as an
      HDM (hardware dependent module). Each module of this layer handles exactly
      one of the peripheral interfaces of a network interface controller (e.g.
      USB, MediaLB, I2C). A module of the application layer is referred to as an
      AIM (application interfacing module). The modules of this layer give 
access
      to MOST via one the following ways: character devices, ALSA, Networking or
      V4L2.

      To physically access MOST, an Intelligent Network Interface Controller
      (INIC) is needed. For more information on available controllers visit:
      www.microchip.com

      staging: unisys: visornic - prevent NETDEV WATCHDOG timeouts after IO 
recovery

      After IO partition recovery, it was possible to get into a situation where
      a visornic device would repeatedly report:

          NETDEV WATCHDOG: eth0 (): transmit queue 0 timed out

      The actual problem would affect any visornic device that was rapidly
      transmitting at the same time the IO partition was being recovered. Once
      you hit the problem, the only way to resume use of the nic would be to
      reboot the Linux client partition.

      The problem was caused by chstat.sent_xmit and chstat.got_xmit_done NOT
      getting cleared during IO partition recovery. This is necessary because
      outstanding xmits would essentially be "abandoned" during such recovery.
      These fields are now cleared in virtnic_serverdown_complete().

      staging: unisys: visornic - ensure proper net locking in tx reset logic

      visornic tx reset handling is done asynchronously via a workqueue in
      visornic_timeout_reset().  As a result, it needs to use rtnl_lock() /
      rtnl_unlock() to lock against possible simultaneous close() of the network
      device.

      (I consulted the bnx2 driver as a model here, as that driver also does
      its tx reset handling asynchronously, just like visornic does.  See

      The return value of the `cmdtest` handler for a subdevice checks the
      prospective new command in various steps and returns the step number at
      which any problem was detected, or 0 if no problem was detected.  It is
      allowed to modify the command in various ways at each step.  Corrections
      for out-of-range values are generally made at step 3, and minor
      adjustments such as rounding are generally made at step 4.

      The `cmdtest` handler for the AO subdevice (`usbduxsigma_ao_cmdtest()`)
      currently range checks the timings at step 3.  Since the running command
      will round down the timings, add code to round them down at step 4.

      staging: comedi: usbduxsigma: don't clobber ao_timer in command test

      `devpriv->ao_timer` is used while an asynchronous command is running on
      the AO subdevice.  It also gets modified by the subdevice's `cmdtest`
      handler for checking new asynchronous commands,
      `usbduxsigma_ao_cmdtest()`, which is not correct as it's allowed to
      check new commands while an old command is still running.  Fix it by
      moving the code which sets up `devpriv->ao_timer` into the subdevice's
      `cmd` handler, `usbduxsigma_ao_cmd()`.

      Note that the removed code in `usbduxsigma_ao_cmdtest()` checked that
      `devpriv->ao_timer` did not end up less that 1, but that could not
      happen due because `cmd->scan_begin_arg` or `cmd->convert_arg` had
      already been range-checked.

      Also note that we tested the `high_speed` variable in the old code, but
      that is currently always 0 and means that we always use "scan" timing
      (`cmd->scan_begin_src == TRIG_TIMER` and `cmd->convert_src == TRIG_NOW`)
      and never "convert" (individual sample) timing (`cmd->scan_begin_src ==
      TRIG_FOLLOW` and `cmd->convert_src == TRIG_TIMER`).  The moved code
      tests `cmd->convert_src` instead to decide whether "scan" or "convert"
      timing is being used, although currently only "scan" timing is
      supported.

      regulator: Add over current protection (OCP) support

      Some regulators can automatically shut down when they detect an
      over current event. Add an op (set_over_current_protection) and a

      Currently the pre-scaler limit is incorrect. The value differs slightly

      spi: davinci: Set prescale value based on register value

      Within davinci_spi_get_prescale() the prescale has two meanings. First one
      being the calculated prescale value and then at the end translates it to 
the
      prescale value that will be written to the SPI register.

      At first glance this can be confusing especially when comparing the 
minimum
      prescale value against what is seen in the TRM.

      To simplify things make it clear that the calculated prescale value will 
always
      be based on the value that will be written into the SPI register.

      ath10k: extend struct htt_mgmt_tx_dec for qca99x0

      HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
      4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
      rate mgmt frame has to go out in the air. It's an optional parameter,
      setting this field to zero will force firmware to choose auto rate
      and send the frame out.

      Those 4 byte info is missed out in the current code and 10.4 firmware
      ended up reading some junk in those 4 byte and sometime malfunctioning.

      Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
      will not process those four byte. So, adding 4 byte at the end of
      struct htt_mgmt_tx_desc will not create any impact on other chipset.

      ath10k: add support for qca99x0 Rx descriptors

      QCA99X0 chip has an extra 4 bytes in rx_msdu_start,
      20 bytes in rx_msdu_end and 20 bytes in rx_ppdu_end structure
      which are used in htt_rx_desc and HTT Rx ring offset setup.
      This is necessary for correct Rx for QCA99X0 or Rx descriptors
      will be overwritten and corrupted.

      With this patch QCA988X and QCA6174 will have extra 44 bytes
      padding in Rx descriptor layout which is harmless.

      rx_ppdu_end_common structure is valid for both of qca998x and
      qca6174, but not for qca99x0 since it has new additional members.
      Hence update the common structure to cover qca99x0 as well.

      ath10k: update tx path to support QCA99X0

      Since QCA99X0 uses fragmentation descriptor differently from
      other ones on tx path, we need to handle it separately.

      QCA99X0 is using 48 bits for address and 16 bits for length
      out of 2 dword and each values have to be programmed by frag
      desc base addr + msdu id, so that hardware can retrieve
      corresponding frag data.

      ath10k: delay device access after cold reset

      It is observed that during cold reset pcie access right
      after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
      Data Bus Error and system hard lockup. The reason
      for bus error is that pcie needs some time to get
      back to stable state for any transaction during cold reset. Add
      delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
      to fix this issue. This patch is tested on QCA988X. This is
      also tested on QCA99X0 which is WIP.

      target: Return descriptor format sense data in case the LU spans 64bit 
sectors

      In case a LU spans 64bit sectors, fixed size sense data information
      field is only 32 bits which means the sector information will be 
truncated.

      Thus, if the LU spans 64bit sectors, use descriptor format sense data to
      correctly report sector information.

      - Add Carrizo support for amdkfd, using the new amdgpu driver as the 
relevant
        kgd. The support includes interfaces with amdgpu both for gfx7 (Kaveri) 
and
        gfx8 (Carrizo). However, gfx7 interface is used for debugging purposes 
only,
        so amdkfd defaults to using radeon when Kaveri is installed.

      I would like to note that no new IOCTLs are being introduced, and there 
is no
      change in the current IOCTLs, as they are suited both for gfx7 and gfx8.

      ARM: OMAP2+: PRCM and hwmod changes for v4.3

      This series adds:

      - I/O wakeup support for AM43xx
      - register lock and unlock support to the hwmod code (needed for the RTC
        IP blocks on some chips)
      - several fixes for sparse warnings and an unnecessary null pointer test
      - a DRA7xx clockdomain configuration workaround, to deal with some 
hardware

      Since I do not have an AM43xx or DRA7xx device, I can't test on those
      platforms.

      perf: Add PERF_RECORD_SWITCH to indicate context switches

      There are already two events for context switches, namely the tracepoint
      sched:sched_switch and the software event context_switches.
      Unfortunately neither are suitable for use by non-privileged users for
      the purpose of synchronizing hardware trace data (e.g. Intel PT) to the
      context switch.

      Tracepoints are no good at all for non-privileged users because they
      need either CAP_SYS_ADMIN or /proc/sys/kernel/perf_event_paranoid <= -1.

      On the other hand, kernel software events need either CAP_SYS_ADMIN or
      /proc/sys/kernel/perf_event_paranoid <= 1.

      Now many distributions do default perf_event_paranoid to 1 making
      context_switches a contender, except it has another problem (which is
      also shared with sched:sched_switch) which is that it happens before
      perf schedules events out instead of after perf schedules events in.
      Whereas a privileged user can see all the events anyway, a
      non-privileged user only sees events for their own processes, in other
      words they see when their process was scheduled out not when it was
      scheduled in. That presents two problems to use the event:

      1. the information comes too late, so tools have to look ahead in the
         event stream to find out what the current state is

      2. if they are unlucky tracing might have stopped before the
         context-switches event is recorded.

      This new PERF_RECORD_SWITCH event does not have those problems
      and it also has a couple of other small advantages.

      It is easier to use because it is an auxiliary event (like mmap, comm
      and task events) which can be enabled by setting a single bit. It is
      smaller than sched:sched_switch and easier to parse.

      To make the event useful for privileged users also, if the
      context is cpu-wide then the event record will be
      PERF_RECORD_SWITCH_CPU_WIDE which is the same as
      PERF_RECORD_SWITCH except it also provides the next or
      previous pid/tid.

      perf tools: Stop copying kallsyms into the perf.data file header

      Since we now ask libtraceevent, the only user of this payload, to use
      perf's symbol resolution routines, there is no need to carry about
      ~4.5MB per perf.data when we can get it from one of the places the perf
      symbol resolution looks for that symtab (debuginfo, ~/.debug/,
      /proc/kallsyms, --symfs, etc), using the kernel and modules build-ids to
      make sure the right table is used.

      perf script: Switch from perf.data's kallsyms to perf's symbol resolver

      We were storing a copy of kallsyms inside perf.data file so that we
      could resolve kernel addresses to function (start, name, mod) tuples,
      but that can be achieved using the symbol resolving routines we have
      in symbols.c, and that are used elsewhere in tools/perf.

      So, do just like 'perf trace' did and ask libtraceevent to use perf's
      symbol resolution routines.

      The next step is to just skip whatever kallsyms data is embedded in
      older perf.data files and finally to stop storing kallsyms in the perf
      data file, as the 20-bytes build-id stored in perf.data's header is
      enough to find out the right symtab (be it ELF, kcore, kallsyms, etc) to
      use.

      tty: core: Improve ldisc debug messages

      Add debug messages for ldisc open and close, and remove
      "closing ldisc" message from tty_ldisc_release(), because a
      close message is now printed for both ldiscs; always print ldisc
      pointer first so ldisc changes are easier to identify.

      tools lib traceevent: Allow setting an alternative symbol resolver

      The perf tools have a symbol resolver that includes solving kernel
      symbols using either kallsyms or ELF symtabs, and it also is using
      libtraceevent to format the trace events fields, including via
      subsystem specific plugins, like the "timer" one.

      To solve fields like "timer:hrtimer_start"'s "function", libtraceevent
      needs a way to map from its value to a function name and addr.

      This patch provides a way for tools that already have symbol resolving
      facilities to ask libtraceevent to use it when needing to resolve
      kernel symbols.

      tty/serial: at91: use 32bit writes into TX FIFO when DMA is enabled

      For now this improvement is only used with TX DMA transfers. The data
      width must be set properly when configuring the DMA controller. Also
      the FIFO configuration must be set to match the DMA transfer data
      width:
      TXRDYM (Transmitter Ready Mode) and RXRDYM (Receiver Ready Mode) must
      be set into the FIFO Mode Register. These values are used by the
      USART to trigger the DMA controller. In single data mode they are not
      used and should be reset to 0.
      So the TXRDYM bits are changed to FOUR_DATA; then USART triggers the
      DMA controller when at least 4 data can be written into the TX FIFO
      througth the THR. On the other hand the RXRDYM bits are left unchanged
      to ONE_DATA.

      Atmel eXtended DMA controller allows us to set a different data width
      for each part of a scatter-gather transfer. So when calling
      dmaengine_slave_config() to configure the TX path, we just need to set
      dst_addr_width to the maximum data width. Then DMA writes into THR are
      split into up to two parts. The first part carries the first data to
      be sent and has a length equal to the greatest multiple of 4 (bytes)
      lower than or equal to the total length of the TX DMA transfer. The
      second part carries the trailing data (up to 3 bytes). The first part
      is written by the DMA into THR using 32 bit accesses, whereas 8bit
      accesses are used for the second part.

      tty/serial: at91: add support to FIFOs

      Depending on the hardware, TX and RX FIFOs may be available. The RX
      FIFO can avoid receive overruns, especially when DMA transfers are
      not used to read data from the Receive Holding Register. For heavy
      system load, The CPU is likely not be able to fetch data fast enough
      from the RHR.

      In addition, the RX FIFO can supersede the DMA/PDC to control the RTS
      line when the Hardware Handshaking mode is enabled. Two thresholds
      are to be set for that purpose:
      - When the number of data in the RX FIFO crosses and becomes lower
        than or equal to the low threshold, the RTS line is set to low
        level: the remote peer is requested to send data.
      - When the number of data in the RX FIFO crosses and becomes greater
        than or equal to the high threshold, the RTS line is set to high
        level: the remote peer should stop sending new data.
      - low threshold <= high threshold
      Once these two thresholds are set properly, this new feature is
      enabled by setting the FIFO RTS Control bit of the FIFO Mode Register.

      FIFOs also introduce a new multiple data mode: the USART works either
      in multiple data mode or in single data (legacy) mode.

      If MODE9 bit is set into the Mode Register or if USMODE is set to
      either LIN_MASTER, LIN_SLAVE or LON_MODE, FIFOs operate in single
      data mode. Otherwise, they operate in multiple data mode.

      In this new multiple data mode, accesses to the Receive Holding
      Register or Transmit Holding Register slightly change.

      Since this driver implements neither the 9bit data feature (MODE9 bit
      set into the Mode Register) nor LIN modes, the USART works in
      multiple data mode whenever FIFOs are available and enabled. We also
      assume that data are 8bit wide.

      In single data mode, 32bit access CAN be used to read a single data
      from RHR or write a single data into THR.
      However in multiple data mode, a 32bit access to RHR now allows us to
      read four consecutive data from RX FIFO. Also a 32bit access to THR
      now allows to write four consecutive data into TX FIFO. So we MUST
      use 8bit access whenever only one data have to be read/written at a
      time.

      USARTs.

      Please be aware that the VERSION register can not be used to guess the
      size of FIFOs. Indeed, for a given hardware version, the USARTs can be
      integrated on Atmel SoCs with different FIFO sizes. Also the
      "atmel,fifo-size" property is optional as older USARTs don't embed FIFO at
      all.

      Besides, the FIFO size can not be read or guessed from other registers:
      When designing the FIFO feature, no dedicated registers were added to
      store this size. Unsed spaces in the I/O register range are limited and
      better reserved for future usages. Instead, the FIFO size of each
      peripheral is documented in the programmer datasheet.

      Finally, on a given SoC, there can be several instances of USART with
      different FIFO sizes. This explain why we'd rather use a dedicated DT
      property than use the "compatible" property.

      serial: imx: reduce irq-latency after rx overflow

      To prevent problems with interrupt latency, and due to the fact, that
      the error will be counted anyway (icount.overrun), the dev_err is simply
      removed.

      Background:
      If an rx-fifo overflow occurs a dev_err message was called in interrupt
      context. Since dev_err messages are written to console in a synchronous 
way
      (unbuffered), and console may be a serial terminal, this leads to a
      highly increased interrupt-latency (several milliseconds).
      As a result of the high latency more rx-fifo overflows will happen, and
      therefore a feedback loop of errors is created.

      serial: sirf: workaround rx process to avoid possible data loss

      when UART works in DMA mode and left bytes in rx fifo less than
      a dma transfer unit, DMA engine can't transfer the bytes out
      to rx DMA buffer. so it need a way to fetch them out and
      flush them into tty buffer in time.

      in the above case, we want UART switch from DMA mode to PIO mode and
      fetch && flush bytes into tty layer buffer until rxfifo become empty,
      after that done let UART switch from PIO mode back to DMA mode.
      (record as method1)

      method1 result in the next receive result wrong. for example in PIO part
      of method1, we fetched && pushed X1...X3 bytes, when UART rxfifo newly
      received Y1...Y4 bytes, UART trigger a DMA unit transfer, the DMA unit's
      content is X1...X3Y1 and rxfifo fifo status is empty, so X1X2X3 pushed
      twice by PIO way and DMA way also the bytes Y2Y3Y4 missed. add rxfifo
      reset operation before UART switch back to DMA mode would resolve the
      issue. ([method1 + do fifo reset] record as method2)

      before the commit, UART driver use method2. but methd2 have a risk of
      data loss, as if UART's shift register receive a complete byte and
      transfer it into rxfifo before rxfifo reset operation the byte will
      loss.

      UART and USP have the similar bits 
CLEAR_RX_ADDR_EN(uart)/FRADDR_CLR_EN(usp),
      When found UART controller changing I/O to DMA mode, UART controller
      clears the two low bits of read point (rx_fifo_addr[1:0]).
      when enable the bit + method1(record as method3), in above example
      the DMA unit's content is X1...X3Y1 and there are Y2Y3Y4 in rxfifo by
      experiment, we just push bytes in rx DMA buffer.

      BTW, the workaround works only for UART receive DMA channel use SINGLE
      DMA mode.

      serial: 8250_omap: workaround errata around idling UART after using DMA

      AM335x, AM437x and DRA7x SoCs have an errata[1] due to which UART
      cannot be idled after it has been used with DMA.

      OMAP3 has a similar sounding errata which has been worked around
      in a2fc36613ac1af2e9 ("ARM: OMAP3: Use manual idle for UARTs
      because of DMA errata"). But the workaround used there does not
      apply to AM335x, AM437x SoCs.

      After using DMA, the UART module on these SoCs must be soft reset
      to go to idle.

      This patch implements that errata workaround. It is expected that
      UART will be used with DMA so no explicit check for DMA usage
      has been added for errata applicability.

      MDR1 register needs to be restored right after soft-reset because
      "UART mode" must be set in that register for module wake-up on AM335x
      to work. As a result, SCR register is now used to determine if
      context was lost during sleep.

      [1] See Advisory 21 in AM437x errata SPRZ408B, updated April 2015.

      serial: 8250_omap: introduce "ti,am3352-uart" compatible property

      Use of of_machine_is_compatible() for handling AM335x specific
      "DMA kick" quirk in 8250_omap driver makes it ugly to extend the
      quirk for other platforms. Instead use a new compatible.

      The new compatible will also make it easier to take care of
      other quirks on AM335x and like SoCs.

      In order to not break backward DTB compatibility for users of
      8250_omap driver on AM335x based boards, existing use of
      of_machine_is_compatible() has not been removed.

      serial: 8250_omap: fix kernel crash in suspend-to-ram

      omap_device infrastructure has a suspend_noirq hook which
      runtime suspends all devices late in the suspend cycle (see
      _od_suspend_noirq() in arch/arm/mach-omap2/omap_device.c)

      This leads to a NULL pointer exception in 8250_omap driver
      since by the time omap8250_runtime_suspend() is called, 8250_dma
      driver has already set rxchan to NULL via serial8250_release_dma().

      Make an explicit check to see if rxchan is NULL in
      runtime_{suspend|resume} hooks to fix this.

      tty: Convert use of __constant_htons to htons

      In little endian cases, macro htons unfolds to __swab16 which
      provides special case for constants. In big endian cases,
      __constant_htons and htons expand directly to the same expression.
      So, replace __constant_htons with htons with the goal of getting
      rid of the definition of __constant_htons completely.

      The semantic patch that performs this transformation is as follows:

      @@expression x;@@

      - __constant_htons(x)
      + htons(x)

      ACPICA: Cleanup use of all non-ANSI local C library functions

      ACPICA commit 7c490c28a18b435c543c6b410e7e7c2131fccc78

      ACPICA implements all non-ANSI functions locally. However, there
      are sometimes two or more versions of the same function throughout
      the ACPICA code. This change fixes this.

      Adds a new file, utilities/utnonansi.c

      ACPICA: MSVC: Fix inclusion order issue of <crtdbg.h>

      ACPICA commit 49c6a6517a906900e9baa51ad5859beeb8a3089f

      The following error logs can be seen for calloc/free/malloc/realloc that
      defined in the stdlib.h:
      ...\stdlib.h(281) : error C2059: syntax error : ','
      ...\stdlib.h(281) : error C2143: syntax error : missing ')' before

      ACPICA: Executer: Add interpreter tracing mode for method tracing facility

      ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b

      The acpi_debug_trace() is the mechanism known as ACPI method tracing that 
is
      used by Linux as ACPICA debugging message reducer. This facility can be
      controlled through Linux ACPI subsystem - /sys/module/acpi/parameters.
      This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace
      logs in the kernel dmesg output.

      This patch enhances acpi_debug_trace() to make it not only a message 
reducer,
      but a real tracer to trace AML interpreter execution. Note that in 
addition
      to the AML tracer enabling, this patch also updates the facility with the
      following enhancements:
      1. Allow a full path to be specified by the acpi_debug_trace() API.
      2. Allow any method rather than just the entrance of 
acpi_evaluate_object()
         to be traced.
      3. All interpreter ACPI_LV_TRACE_POINT messages are collected for
         ACPI_EXECUTER layer.

      The Makefile of drivers/acpi/acpica is also updated to include exdebug.o
      and the duplicated stubs are removed after that.

      Note that since this patch has enhanced the method tracing facility, Linux
      need also be updated after applying this patch. Lv Zheng.

      ACPICA: Dispatcher: Add trace support for interpreter

      ACPICA commit 71299ec8b49054daace0df50268e8e055654ca37

      This patch adds trace point at the following point:
       1. Begin/end of a control method execution;
       2. Begin/end of an opcode execution.

      The trace point feature can be enabled by defining ACPI_DEBUG_OUTPUT
      and specifying a debug level that includes ACPI_LV_TRACDE_POINT and the
      debug layers that include ACPI_PARSER and ACPI_DISPACTCHER.

      In order to make aml_op_name of union acpi_parse_object usable for 
tracer, it is
      enabled for ACPI_DEBUG_OUTPUT in this patch. Lv Zheng.

      ACPICA: Dispatcher: Move stack traversal code to dispatcher

      ACPICA commit c8275e243b58fd4adfc0362bd704af41ed14bc75

      This patch moves parts of acpi_dm_dump_method_info() to the dispatcher
      component.

      This patch also makes the new function dependent on ACPI_DEBUG_OUTPUT
      compile-stage definition so that it can be used by the trace facility.

      acpi_dm_dump_method_info() traverses method stack when an exception is
      encountered. Such traversal is needed to support method tracing for the
      exceptions. When an exception is encountered, the end indications of the
      aborted methods should be logged in order not to break the user space
      analysis tool. Lv Zheng.

      ACPICA: Namespace: Add function to directly return normalized full path

      ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea

      This patch adds functions to return normalized full path instead of
      "external path". The external path contains trailing "_" for each
      name segment while the normalized full path doesn't contain the
      trailing "_".

      Currently this function is used by the method tracing users to specify a
      none trailing "_" attached name path. Lv Zheng.

      Note that we need to validate and switch all Linux kernel acpi_get_name()
      users to use the new name type before removing the old name type from
      ACPICA.

      ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address 
assignments

      ACPICA commit afb52611dbe7403551f93504d3798534f5c343f4

      This patch cleans up the code of assigning the AML address to the
      union acpi_operand_object.

      The idea behind this cleanup is:
      The AML address of the union acpi_operand_object should always be 
determined at
      the point where the object is encountered. It should be started from the
      first byte of the object. For example, the opcode of the object, the name
      string of the user_term object, or the first byte of the packaged object
      (where a pkg_length is prefixed). So it's not cleaner to have it assigned
      here and there in the entire ACPICA source tree.

      There are some special cases for the internal opcodes, before cleaning up
      the internal opcodes, we should also determine the rules for the AML
      addresses of the internal opcodes:
      1. INT_NAMEPATH_OP: the address of the first byte for the name_string.
      2. INT_METHODCALL_OP: the address of the first byte for the name_string.
      3. INT_BYTELIST_OP: the address of the first byte for the byte_data list.
      4. INT_EVAL_SUBTREE_OP: the address of the first byte for the
                              Region/Package/Buffer/bank_field/Field arguments.
      5. INT_NAMEDFIELD_OP: the address to the name_seg.
      6. INT_RESERVEDFIELD_OP: the address to the 0x00 prefix.
      7. INT_ACCESSFIELD_OP: the address to the 0x01 prefix.
      8. INT_CONNECTION_OP: the address to the 0x02 prefix.
      9: INT_EXTACCESSFIELD_OP: the address to the 0x03 prefix.
      10.INT_RETURN_VALUE_OP: the address of the replaced operand.
      11.computational_data: the address to the
                            Byte/Word/Dword/Qword/string_prefix.

      Before cleaning up the internal root scope of the aml_walk, turning it 
into
      the term_list, we need to remember the aml_start address as the "Aml"
      attribute for the union acpi_operand_object created by 
acpi_ps_create_scope_op().

      Finally, we can delete some redundant AML address assignment in psloop.c.

      ACPICA: Parser: Cleanup aml_offset in union acpi_operand_object

      ACPICA commit 61b360074fde2bb8282722579410f5d1fb12f84d

      This patch converts aml_offset in union acpi_operand_object to AML 
address.

      AML offset is actually only used by the debugger, using AML address is 
more
      direct and efficient during the parsing stage so that we don't need to
      calculate the offset during the parsing stage and will not have
      difficulities in converting it into other offset attributes.

      Sometimes, aml_offset is not an indication of the offset from the table
      header but the offset from the entry of a list of terms, which requires
      additional efforts to convert it into an offset from the table header. By
      using AML address directly, there is no such difficulty.
      Thus this patch also deletes a logic in disassembler that is trying to
      convert the aml_offset from
        "offset from the start address of Method/Package/Buffer"
      into the
        "offset from the start address of the ACPI table"
      (Sample code deletion can be seen in acpi_dm_deferred_parse(), but the
      function is not in the Linux kernel). Lv Zheng.

      ACPICA: Parser: Cleanup aml_offset in struct acpi_walk_state

      ACPICA commit d254405814495058276c0c2f9d96794d15a6c91c

      This patch converts aml_offset in struct acpi_walk_state to AML address.

      AML offset is actually only used by the debugger, using AML address is 
more
      direct and efficient during the parsing stage so that we don't need to
      calculate it during the parsing stage.

      On the other hand, we can see several issues in the current parser logic
      around the aml_offset:
      1. union acpi_operand_object.Common.aml_offset is redundantly assigned in
         acpi_ps_parse_loop().
      2. aml_offset is not an indication of the offset from the table header but
         the offset from the entry of a list of objects. Sometimes, it indicates
         an entry for a Method/Package/Buffer, which makes it difficult to be
         reversely calculated to a table header offset.
      3. When being used with method tracers (for example, Linux function 
trace),
         it's better to have AML address logged instead of the AML offset 
because
         the address is the only attribute that can uniquely identify the 
opcode.
      This patch is required to solve the above issues. Lv Zheng.

      iio: fix drivers that consider 0 as a valid IRQ in client->irq

      Since patch "i2c / ACPI: Use 0 to indicate that device does not have
      interrupt assigned" [1], 0 is not a valid i2c client irq anymore, so
      change all driver's checks accordingly.

      The same issue occurs when the device is instantiated via device tree
      with no IRQ, or from the i2c sysfs interface, even before the patch
      above.

      fs: Remove ext3 filesystem driver

      The functionality of ext3 is fully supported by ext4 driver. Major
      distributions (SUSE, RedHat) already use ext4 driver to handle ext3
      filesystems for quite some time. There is some ugliness in mm resulting
      from jbd cleaning buffers in a dirty page without cleaning page dirty
      bit and also support for buffer bouncing in the block layer when stable
      pages are required is there only because of jbd. So let's remove the
      ext3 driver. This saves us some 28k lines of duplicated code.

      ASoC: rl6231: add pll preset table

      Currently, rl6231_pll_calc provide a working PLL parameters for
      given freq_in and freq_out. However, in some cases it is not the
      perfect parameter. For example if freq_in = 19200000 and freq_out
       = 24576000, the calculated parameter will gengrate 24.5647 MHz
      which is not exactly the same as what we need. But the PLL can
      output 24.576 MHz as exactly what we expect if we set the best
      PLL parameter.
      To improve it, we put the best match parameters in a preset table.
      We can search the preset table first, if there is no preset parameter
      for the given freq_in and freq_out, we can still calculate a working
      PLL parameter.

      This IP is shared with Watchdog and RTC functionality.  All 3 of
      these devices are mutually exclusive from one another i.e. Only 1
      IP can be used at any given time.  We use the device-driver model
      combined with a DT 'mode' property to enforce this.

      The ST LPC Clocksource IP can be used as the system (tick) timer.

      PCI: Call pci_read_bridge_bases() from core instead of arch code

      When we scan a PCI bus, we read PCI-PCI bridge window registers with
      pci_read_bridge_bases() so we can validate the resource hierarchy.  Most
      architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but
      PCI-PCI bridges are not arch-specific, so this doesn't need to be in
      arch-specific code.

      Call pci_read_bridge_bases() directly from the PCI core instead of from
      arch code.

      For alpha and mips, we now call pci_read_bridge_bases() always; previously
      we only called it if PCI_PROBE_ONLY was set.

      Slave latency range has been changed in Core Spec. 4.2 by Erratum 5419
      of ESR08_V1.0.0. And it should be applied to Core Spec. 4.0 and 4.1.

      Before:
         connSlaveLatency <= ((connSupervisionTimeout / connIntervalMax) - 1)

      After:
         connSlaveLatency <= ((connSupervisionTimeout / (connIntervalMax*2)) - 
1)

      This patch makes hci_check_conn_params() check the allowable slave

      Bluetooth: __l2cap_wait_ack() add defensive timeout

      Add a timeout to prevent the do while loop running in an
      infinite loop. This ensures that the channel will be
      instructed to close within 10 seconds so prevents
      l2cap_sock_shutdown() getting stuck forever.

      Returns -ENOLINK when the timeout is reached. The channel
      will be subequently closed and not all data will be ACK'ed.

      Bluetooth: Make __l2cap_wait_ack more efficient

      Use chan->state instead of chan->conn because waiting
      for ACK's is only possible in the BT_CONNECTED state.
      Also avoids reference to the conn structure so makes
      locking easier.

      Only call __l2cap_wait_ack() when the needed condition
      of chan->unacked_frames > 0 && chan->state == BT_CONNECTED
      is true and convert the while loop to a do while loop.

      __l2cap_wait_ack() change the function prototype to
      pass in the chan variable as chan is already available
      in the calling function l2cap_sock_shutdown(). Avoids
      locking issues.

      Bluetooth: L2CAP ERTM shutdown protect sk and chan

      During execution of l2cap_sock_shutdown() which might
      sleep, the sk and chan structures can be in an unlocked
      condition which potentially allows the structures to be
      freed by other running threads. Therefore, there is a
      possibility of a malfunction or memory reuse after being
      freed.

      Keep the sk and chan structures alive during the
      execution of l2cap_sock_shutdown() by using their
      respective hold and put functions. This allows the structures
      to be freeable at the end of l2cap_sock_shutdown().

      This patch introduces suspend and resume callbacks to mac802154. When
      doing suspend we calling the stop driver callback which should stop the

      Calling resume will call the start driver callback, which starts receiving
      again and allow to transmit frames.

      This was tested only with the fakelb driver and a qemu vm by doing the
      following commands:

      echo "devices" > /sys/power/pm_test
      echo "freeze" > /sys/power/state

      PCI: designware: Don't complain missing *config* reg space if va_cfg0 is 
set

      Currently on Keystone SoCs, we always complain:

        keystone-pcie 21021000.pcie: missing *config* reg space

      Keystone uses an older version of DesignWare hardware that doesn't have
      ATU support.  So va_cfg0_base and va_cfg1_base are already set up in
      ks_dw_pcie_host_init() before calling dw_pcie_host_init(), and they point
      to the remote config space address va (both same for Keystone).  Add a
      check to avoid this boot noise on Keystone.

      regulator: tps6586x: silence pointer-to-int-cast

      of_regulator_match.driver_data is (void *).  tps6586x uses it to store an
      anonymous enum value (those TPS6586X_ID_ values).

      Later, it tries to extract the ID by casting directly to an int, which is 
a
      no-no ([-Wpointer-to-int-cast]):

      drivers/regulator/tps6586x-regulator.c: In function 
'tps6586x_parse_regulator_dt':
      drivers/regulator/tps6586x-regulator.c:430:8: warning: cast from pointer 
to integer of different size [-Wpointer-to-int-cast]
         id = (int)tps6586x_matches[i].driver_data;
              ^

      Instead of casting to int, uintptr_t is better suited for receiving and
      comparing integers extracted from void *.  This is especially true on
      64-bit systems where sizeof(void *) != sizeof(int).

      netfilter: fix possible removal of wrong hook

      nf_unregister_net_hook() uses the nf_hook_ops fields as tuple to look up 
for
      the corresponding hook in the list. However, we may have two hooks with 
exactly
      the same configuration.

      This shouldn't be a problem for nftables since every new chain has an 
unique
      priv field set, but this may still cause us problems in the future, so 
better
      address this problem now by keeping a reference to the original 
nf_hook_ops
      structure to make sure we delete the right hook from 
nf_unregister_net_hook().

      ext4, jbd2: add REQ_FUA flag when recording an error in the superblock

      When an error condition is detected, an error status should be recorded 
into
      superblocks of EXT4 or JBD2. However, the write request is submitted now
      without REQ_FUA flag, even in "barrier=1" mode, which is followed by
      panic() function in "errors=panic" mode. On mobile devices which make
      whole system reset as soon as kernel panic occurs, this write request
      containing an error flag will disappear just from storage cache without
      written to the physical cells. Therefore, when next start, even forever,
      the error flag cannot be shown in both superblocks, and e2fsck cannot fix
      the filesystem problems automatically, unless e2fsck is executed in
      force checking mode.

      This driver fully supports VF drivers using both the 1.0 and 1.1
      versions of the virtual channel API. However, VF drivers using
      version 1.0 get upset if we provide them with a version other than
      that, and refuse to play with us.

      Correct this by checking the VFs API version at the time that we
      store it off, and provide the correct version number back to the VF
      so we can all get along.

      i40evf: handle big resets

      The most common type of reset that the VF will encounter is a PF reset
      that cascades down into a VF reset for each VF. In this case, the VF
      will always be assigned the same VSI and recovery is fairly simple.

      However, in the case of 'bigger' resets, such as a Core or EMP reset,
      when the device is reinitialized, it's probable that the VF will NOT get
      the same VSI. When this happens, the VF will not be able to recover, as
      it will continue to request resources for its original VSI.

      Add an extra state to the admin queue state machine so that the driver
      can re-request its configuration information at runtime. During reset
      recovery, set this bit in the aq_required field, and fetch the (possibly
      new) configuration information before attempting to bring the driver
      back up. Since the driver doesn't know what kind of reset it has
      encountered, this step is done even for a PF reset, but it doesn't hurt
      anything - it just gets the same VSI back.

      i40e: add VF capabilities to virtual channel interface

      To prepare for the changes coming up in the X722 device and future
      devices, the virtual channel interface has to change slightly. The VF
      driver can now report what its capable of supporting, which then informs
      the PF driver when it sends the configuration information back to the
      VF.

      A 1.1 VF driver on a 1.0 PF driver should not send its capabilities.
      Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect
      or depend upon receiving the VF capabilities.

      All other aspects of the API are unchanged.

      This patch changes the switch statement for dynamic interrupt throttling

      The reports sent from some touch devices (e.g. the Cintiq 24HDT) contain
      junk data in the contact slots which follow the final "valid" contact.
      To avoid forwarding it to usrspace, we store the reported contact count
      during the pre-process phase and then only process that many contacts.
      If a device sends its contacts across multiple reports (what Microsoft

      reports other than the first.

      HID: wacom: Perform all event processing as part of report processing

      In some cases, we need access to information before it becomes available
      to the 'event' handler. In particular, for some devices we cannot properly
      process the finger data without first knowing the "contact count" at the
      very end of the report (e.g. the Cintiq 24HDT touch screen, when forced
      through the GENERIC codepath).

      Since the HID subsystem doesn't provide a way to take action before 
'event'
      is called, we take a cue from hid-multitouch.c and add a pre-process step
      within the 'report' handler that performs the same function.

      ixgbevf: add support for reporting RSS key and hash table for X550

      This patch extends the reporting of the RSS key and hash table by
      adding support for X550 VFs. The difference is that X550 VFs have
      their own registers for RSS key and indirection table, so there is
      no need to query the PF.

      The RSS key and indirection table are stored in the adapter structure
      during the configuration of VFRSSRK and VFRETA which in turn can be
      used in ethtool for reporting.

      The logic for writing VFRETA is also changed to make sure that the
      indirection table is reported correctly.

      In addition this patch adds defines for the VFRETA entries and number
      of VFRSSRK registers as well as some whitespace cleanups.

      crypto: nx - make platform drivers directly register with crypto

      Remove the common 'platform' registration module, and move the crypto
      compression driver registration into each of the pSeries and PowerNV
      platform NX 842 drivers.  Change the nx-842.c code into simple common
      functions that each platform driver uses to perform constraints-based
      buffer changes, i.e. realigning and/or resizing buffers to match the
      driver's hardware requirements.

      The common 'platform' module was my mistake to create - since each
      platform driver will only load/operate when running on its own
      platform (i.e. a pSeries platform or a PowerNV platform), they can
      directly register with the crypto subsystem, using the same alg and
      driver name.  This removes unneeded complexity.

      powerpc: Use hardware RNG for arch_get_random_seed_* not arch_get_random_*

      The hardware RNG on POWER8 and POWER7+ can be relatively slow, since
      it can only supply one 64-bit value per microsecond.  Currently we
      read it in arch_get_random_long(), but that slows down reading from
      /dev/urandom since the code in random.c calls arch_get_random_long()
      for every longword read from /dev/urandom.

      Since the hardware RNG supplies high-quality entropy on every read, it
      matches the semantics of arch_get_random_seed_long() better than those
      of arch_get_random_long().  Therefore this commit makes the code use
      the POWER8/7+ hardware RNG only for arch_get_random_seed_{long,int}
      and not for arch_get_random_{long,int}.

      This won't affect any other PowerPC-based platforms because none of
      them currently support a hardware RNG.  To make it clear that the
      ppc_md function pointer is used for arch_get_random_seed_*, we rename
      it from get_random_long to get_random_seed.

      powerpc/rtas: Introduce rtas_get_sensor_fast() for IRQ handlers

      The EPOW interrupt handler uses rtas_get_sensor(), which in turn
      uses rtas_busy_delay() to wait for RTAS becoming ready in case it
      is necessary. But rtas_busy_delay() is annotated with might_sleep()
      and thus may not be used by interrupts handlers like the EPOW handler!

      If the pin controller probes before the GPIO driver it needs to
      populate the GPIO driver state containers ahead of the actual

      KVM: svm: handle KVM_X86_QUIRK_CD_NW_CLEARED in svm_get_mt_mask

      We can disable CD unconditionally when there is no assigned device.
      KVM now forces guest PAT to all-writeback in that case, so it makes
      sense to also force CR0.CD=0.

      When there are assigned devices, emulate cache-disabled operation
      through the page tables.  This behavior is consistent with VMX
      microcode, where CD/NW are not touched by vmentry/vmexit.  However,
      keep this dependent on the quirk because OVMF enables the caches
      too late.

      KVM: nVMX: VMX instructions: add checks for #GP/#SS exceptions

      According to Intel SDM several checks must be applied for memory operands
      of VMX instructions.

      Long mode: #GP(0) or #SS(0) depending on the segment must be thrown
      if the memory address is in a non-canonical form.

      Protected mode, checks in chronological order:
      - The segment type must be checked with access type (read or write) taken
      into account.
        For write access: #GP(0) must be generated if the destination operand
                is located in a read-only data segment or any code segment.
        For read access: #GP(0) must be generated if if the source operand is
                located in an execute-only code segment.
      - Usability of the segment must be checked. #GP(0) or #SS(0) depending on 
the
        segment must be thrown if the segment is unusable.
      - Limit check. #GP(0) or #SS(0) depending on the segment must be
        thrown if the memory operand effective address is outside the segment
        limit.

      staging: unisys: Fix improper use of NETDEV_TX_BUSY

      Using NETDEV_TX_BUSY is tricky.  Its meant for situations where the error
      in question is transient and quickly resolved.  But the driver rarely is
      able to know that to a certainty.  And in the case of visornic, it just
      uses it without any care for that, in the hopes that it won't loose 
frames,
      even if the problem is that the skb is somehow malformed for the hardware.
      If we get one of those kinds of skbs, NETDEV_TX_BUSY will just cause us to
      spin, processing the same error over and over.

      Fix it by dropping the frame, stopping the queue where appropriate, and
      returning NETDEV_TX_OK

      As pointed out in a recent review, the num_visornic_open array didn't do
      anything useful, and it exposed a potential race in the visornic code that
      could arise while taking down a net interface while reading from the
      debugfs files. Fix that by removing the array entirely, and just iterating
      over all the registered netdevs in a given namespace, filtering on them
      having visornic ops (to identify which are ours), and having their queues
      not be stopped (identifying that they are up). This should prevent any 
oops
      conditions happening due to changing state in that array, and save us a
      bunch of code too.

      staging/comedi/drivers/usbduxsigma.c: added support for ehci drivers

      urb->interval is deprecated and thus I've changed the driver
      that it now always assumes interval=1 which means every frame
      in USB 1.1 and every uframe in USB 2.0. However we still need
      to have different sampling rates which are still multiples
      of the interval which is now transmitted to the firmware.
      The firmware transmits either zero length packets or none every (u)frame.
      This is checked in the completion handler and any packet
      at zero length is discarded so that comedi again sees the data
      coming in at the interval specified. This also then gives the ADC
      the necessary time to convert. For example 16 channels require
      about 700us and in this period no packet could be transmitted.
      In this case this is padded up to 1ms so that we have then 7 zero
      length packets and one packet with the ADC data.

      Drop more omap3 legacy board-*.c files for v4.3. This time we're
      dropping the board files for omap3logic and omap3pandora.

      The reason for dropping these now rather than later is that now
      we can simply revert the patches in case of unexpected issues as
      we are not dropping any platform data at this point.

      This leaves us with only the following board-*.c files:

      BOARD                   REASON NEEDED
      board-ldp.c             Still used in RMKs boot test system
      board-rx51-*.c          Needs /proc/atags support for user space

      Once we have the n900 legacy user space issues sorted out for
      /proc/atags and system_rev, we can drop the remaining two
      board-*.c files. And then one merge window after that we can
      drop the legacy booting support assuming no unexpected issues
      are found.

      memory: pl172: fix modular build

      Building pl172 as a module fails with:
      > ERROR: "of_default_bus_match_table" [drivers/memory/pl172.ko] undefined!

      Because the symbol of_default_bus_match_table isn't exported by the OF
      core code so can't be referenced from modules. Fix this by removing
      the usage of of_default_bus_match_table for now. The side effect of
      this is that child nodes can't use "simple-bus" or "simple-mfd".

      rcu: Don't disable CPU hotplug during OOM notifiers

      RCU's rcu_oom_notify() disables CPU hotplug in order to stabilize the
      list of online CPUs, which it traverses.  However, this is completely
      pointless because smp_call_function_single() will quietly fail if invoked
      on an offline CPU.  Because the count of requests is incremented in the
      rcu_oom_notify_cpu() function that is remotely invoked, everything works
      nicely even in the face of concurrent CPU-hotplug operations.

      Furthermore, in recent kernels, invoking get_online_cpus() from an OOM
      notifier can result in deadlock.  This commit therefore removes the
      call to get_online_cpus() and put_online_cpus() from rcu_oom_notify().

      The synchronize_rcu_expedited() and synchronize_sched_expedited()
      expedited-grace-period primitives induce OS jitter, which can degrade

      Note that this patch does not warn on synchronize_srcu_expedited()

      rcu: Create a synchronize_rcu_mult()

      There have been several requests for a primitive that waits for
      grace periods for several RCU flavors concurrently, so this
      commit creates it.  This is a variadic macro, and you pass in
      the call_rcu() functions of the flavors of RCU that you wish to
      wait for.

      Note that you cannot pass in call_srcu() for two reasons: (1) This
      would result in a type mismatch and (2) You need to specify which
      srcu_struct you want to use.  Handle this by creating a wrapper
      function for your SRCU domain, for example:

        void call_srcu_mine(struct rcu_head *head, rcu_callback_t func)
        {
                call_srcu(&ss_mine, head, func);
        }

      You can then do something like this:

        synchronize_rcu_mult(call_srcu_mine, call_rcu, call_rcu_sched);

      The get_state_synchronize_rcu() and cond_synchronize_rcu() functions

      cpufreq: acpi-cpufreq: Fix up the handling of cpb sysfs attribute

      The cpb sysfs attribute is only exposed by the ACPI cpufreq driver
      after a runtime check.  For this purpose, the driver keeps a NULL
      placeholder in its table of sysfs attributes and replaces the NULL
      with a pointer to an attribute structure if it decides to expose
      cpb.

      That is confusing, so make the driver set the pointer to the cpb

      After commit 8cfcfd39000d (acpi-cpufreq: Fix an ACPI perf unregister
      issue) we store both a pointer to per-CPU data of the first policy
      CPU and the number of that CPU which are redundant.

      Since the CPU number has to be stored anyway for the unregistration,
      the pointer to the CPU's per-CPU data may be dropped and we can
      access the data in question via per_cpu_ptr().

      PCI: iproc: Add arm64 support

      Add arm64 support to the iProc PCIe driver.

      Note that on arm32, bus->sysdata points to the arm32-specific pci_sys_data
      struct, and pci_sys_data.private_data contains the iproc_pcie pointer.
      For arm64, there's nothing corresponding to pci_sys_data, so we keep the
      iproc_pcie pointer directly in bus->sysdata.

      In addition, arm64 does IRQ mapping in pcibios_add_device(), so it doesn't
      need pci_fixup_irqs() as arm32 does.

      This patch series does several things - it updates the bnx2x FW into
      7.12.30 which both contains some small fixes as well as opening the door
      for several new features for the device - mainly vxlan/geneve offloads
      and vlan filtering offload.
      It then adds a new Multi-function mode [BD] which requires this FW in
      order to operate.

      In addition, this finally rebrands the driver from a 'broadcom' driver
      into a 'qlogic' driver [although it would still reside under Broadcom's
      tree in the kernel].

      using specific debug tools.

      This patch adds the necessary part in the driver in order to make the
      feature operational, as well as update users [under debug] during load
      in case their device contains a dump of a previous crash.

      bnx2x: Utilize FW 7.12.30

      This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:

       - Packets from a VF with pvid configured which were sent with a
         different vlan were transmitted instead of being discarded.

       - FCoE traffic might not recover after a failue while there's traffic
         to another function.

      In addition, this FW opens the door for the driver to implement several
      new features; Specifically, this enhances the device's support for
      encapsulated packets and will allow vxlan/geneve offloads to be added in
      the future, as well as vlan filtering offload.

      genirq/MSI: Reorginize struct msi_desc to prepare for support of generic 
MSI

      Reorganize struct msi_desc so it could be reused by other MSI
      drivers. We have the following layout now:

      struct msi_desc {
             /* Shared device/bus independent data */
             ...
             union {
                     /* PCI specific data */
             struct {
                    ...
             };
             };
      };

      We need to have anonymous union and a anonymous structure for the PCI
      fields, otherwise we would have to change all instances using these
      fields.

      For non PCI devices we will enforce a proper namespace and a non
      anonymous structure.

      irqchip: omap-intc: Improve IRQ handler

      As it turns out the current IRQ number will *always* be available from
      SIR register which renders the reads of PENDING registers as plain
      unnecessary overhead.

      In order to catch any situation where SIR reads as zero, we're adding
      a WARN() to turn it into a very verbose error and users actually
      report it.

      With this patch average running time of omap_intc_handle_irq() reduced
      from about 28.5us to 19.8us as measured by the kernel function
      profiler.

      Tested with BeagleBoneBlack Rev A5C.

      Two nice things here:
      - drm_dev_register will truly register everything in the right order
        if the driver doesn't have a ->load callback. Before this we had to
        init the primary mode_group after the device nodes where already
        registered.

      - Less things to keep track of when reworking the connector locking,

      drm: Stop filtering according to mode_group in getresources

      It's been dead code since forever since mode groups haven't ever been
      implemented. On top of that it's also been non-functional since we
      only ever filtered the getresources ioctl and not any of the others
      nor the mode object lookup code.

      Given overwhelming evidence it looks like this isn't a feature we

      drm: Roll out drm_for_each_connector more

      Now that we also grab the connection_mutex and so fixed the race with
      atomic modeset we can use the iterator there too.

      The other special case is drm_connector_unplug_all which would have a
      locking inversion with the sysfs store/show functions if we'd grab the
      mode_config.mutex around the unplug. We could just grab
      connection_mutex instead, but that's a bit too much a dirty trick for
      my taste. Also it's only used by udl, which doesn't do any other kind
      of connector hotplugging, so should be race-free. Hence just stick
      with a comment for now.

      drm/i915: Take all modeset locks for DP MST hotplug

      While auditing various users of the connector/encoder lists I realized
      that the atomic code is a very prolific user of them. And it only ever
      grabs the mode_config->connection_mutex, but not the
      mode_config->mutex like all the other code walking encoder/connector
      lists.

      The problem is that we can't grab the mode_config.mutex late in atomic
      code since that would lead to locking inversions. And we don't want to
      grab it unconditionally like the legacy set_config modeset path since
      that would render all the fine-grained locking moot.

      Instead just grab more locks in the dp mst hotplug code. Note that
      drm_connector_init (which is the one adding the connector to these
      lists) already uses drm_modeset_lock_all.

      The other reason for grabbing all locks is that the dpms off in the
      unplug function amounts to a modeset, so better to take all required
      locks for that.

      Ever since framebuffers are reference counted we have a special lock
      for the global fb list. Make sure users of that list do hold that

      drm: Check locking in drm_for_each_connector

      Because of DP MST connectors can now be hotplugged and we must hold
      the right lock when walking the connector lists.  Enforce this by
      checking the locking in our shiny new list walking macros.

      v2: Extract the locking check into a small static inline helper to
      help readability. This will be more important when we make the
      read list access rules more complicated in later patches. Inspired by
      comments from Chris. Unfortunately, due to header loops around the
      definition of struct drm_device the function interface is a bit funny.

      v3: Encoders aren't hotadded/removed. For each dp mst encoder we
      statically create one fake encoder per pipe so that we can support as
      many mst sinks as the hw can (Dave).

      drm/fbdev-helper: Grab mode_config.mutex in 
drm_fb_helper_single_add_all_connectors

      This is now truly only duct-tape to keep locking checks happy since
      calling this function when hpd or polling are already enabled is a
      bug. The fbdev helper can't cope with hotplug changes yet at this
      point, only after that.

      Otoh a bit more robustness in this function can't hurt, and with this
      fbdev can actually cope with hotplug changes. And it's also more
      consistent with the connector hotadd/remove dp mst needs to do.
      Therefore document this as new official behavior.

      drm/probe-helper: Grab mode_config.mutex in poll_init/enable

      So on first looks this seems superflous since drivers should ensure
      correct ordering to not make this a problem. Otoh ordering constraints
      between hdp, fbdev load and enabling polling are already tricky on
      some hardware and it helps to be more robust.

      But the real goal is to just shut up a locking WARN_ON I'd like to
      add, which means init code gets some additional locks just for
      uniformity.

      v2: Also grab the lock for the public poll_enable, not just poll_init
      which is used for resume, with the same justification.

      ARM: STi: Add code to release secondary cores from holding pen.

      Most upstream devs boot STi platform via JTAG which abuses the
      boot process by setting the PC of secondary cores directly. As
      a consquence, booting STi platforms via u-boot results in only
      the primary core being brought up as the code to manage the
      holding pen is not upstream.

      This patch adds the necessary code to bring the secondary cores
      out of the holding pen. It uses the cpu-release-addr DT property
      to get the address of the holding pen from the bootloader.

      Currently HPD_PORT_A is used as an alias for HPD_NONE to mean that the

      s390/cio: Implement proper Link Incident Record handling

      A hardware problem on a FICON link is reported by the Channel Subsystem
      to the operating system via a Link Incident Record (LIR). In response,
      the operating system should issue a message that enables hardware
      service personnel to identify and repair the failing component.

      Current Linux LIR handling is broken because LIR data is incorrectly
      interpreted and no log message is generated.

      This patch fixes Linux LIR handling by implementing a new log message
      for LIRs indicating a degraded or non-operational link. Also LIRs are
      no longer used to deactivate channel paths because the available data
      does not reliably allow to determine the affected channel path.

      the s390_do_machine_check function will be called. The call to

      s390/kvm: integrate HANDLE_SIE_INTERCEPT into cleanup_critical

      Currently there are two mechanisms to deal with cleanup work due to
      interrupts. The HANDLE_SIE_INTERCEPT macro is used to undo the changes
      required to enter SIE in sie64a. If the SIE instruction causes a program
      check, or an asynchronous interrupt is received the HANDLE_SIE_INTERCEPT
      code forwards the program execution to sie_exit.

      All the other critical sections in entry.S are handled by the code in
      cleanup_critical that is called by the SWITCH_ASYNC macro.

      Move the sie64a function to the beginning of the critical section and
      add the code from HANDLE_SIE_INTERCEPT to cleanup_critical. Add a special
      case for the sie64a cleanup to the program check handler.

      s390/kvm: fix interrupt race with HANDLE_SIE_INTERCEPT

      The HANDLE_SIE_INTERCEPT macro is used in the interrupt handlers
      and the program check handler to undo a few changes done by sie64a.
      Among them are guest vs host LPP, the gmap ASCE vs kernel ASCE and
      the bit that indicates that SIE is currently running on the CPU.

      There is a race of a voluntary SIE exit vs asynchronous interrupts.
      If the CPU completed the SIE instruction and the TM instruction of
      the LPP macro at the time it receives an interrupt, the interrupt
      handler will run while the LPP, the ASCE and the SIE bit are still
      set up for guest execution. This might result in wrong sampling data,
      but it will not cause data corruption or lockups.

      The critical section in sie64a needs to be enlarged to include all
      instructions that undo the changes required for guest execution.

      s390/kernel: lazy restore fpu registers

      Improve the save and restore behavior of FPU register contents to use the
      vector extension within the kernel.

      The kernel does not use floating-point or vector registers and, therefore,
      saving and restoring the FPU register contents are performed for handling
      signals or switching processes only.  To prepare for using vector
      instructions and vector registers within the kernel, enhance the save
      behavior and implement a lazy restore at return to user space from a
      system call or interrupt.

      To implement the lazy restore, the save_fpu_regs() sets a CPU information
      flag, CIF_FPU, to indicate that the FPU registers must be restored.
      Saving and setting CIF_FPU is performed in an atomic fashion to be
      interrupt-safe.  When the kernel wants to use the vector extension or
      wants to change the FPU register state for a task during signal handling,
      the save_fpu_regs() must be called first.  The CIF_FPU flag is also set at
      process switch.  At return to user space, the FPU state is restored.  In
      particular, the FPU state includes the floating-point or vector register
      contents, as well as, vector-enablement and floating-point control.  The
      FPU state restore and clearing CIF_FPU is also performed in an atomic
      fashion.

      For KVM, the restore of the FPU register state is performed when restoring
      the general-purpose guest registers before the SIE instructions is 
started.
      Because the path towards the SIE instruction is interruptible, the CIF_FPU
      flag must be checked again right before going into SIE.  If set, the guest
      registers must be reloaded again by re-entering the outer SIE loop.  This
      is the same behavior as if the SIE critical section is interrupted.

      The kvm_arch_vcpu_load() does not validate whether the floating-point
      control (FPC) is valid.  Further, the return code of the restore is not
      checked too.  If the FPC is invalid, the restore fails and the host FPC
      value might remain.  The correct behavior would be to clear the FPC if it
      is not valid.  Hence, validate the FPC value and, optionally, reset the
      value before restoring it.

      ARM: zynq: Set bit 22 in PL310 AuxCtrl register (6395/1)

      This patch is based on the
      commit 1a8e41cd672f ("ARM: 6395/1: VExpress: Set bit 22 in the PL310
      (cache controller) AuxCtlr register")

      Clearing bit 22 in the PL310 Auxiliary Control register (shared
      attribute override enable) has the side effect of transforming Normal
      Shared Non-cacheable reads into Cacheable no-allocate reads.

      Coherent DMA buffers in Linux always have a cacheable alias via the
      kernel linear mapping and the processor can speculatively load cache
      lines into the PL310 controller. With bit 22 cleared, Non-cacheable
      reads would unexpectedly hit such cache lines leading to buffer
      corruption.

      For Zynq, this fix avoids memory inconsistencies between Gigabit
      Ethernet controller (GEM) and CPU when DMA_CMA is disabled.

      x86/build: Fix detection of GCC -mpreferred-stack-boundary support

      As per:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53383

      GCC only allows -mpreferred-stack-boundary=3 on x86_64 if -mno-sse is set.
      That means that cc-option will not detect -mpreferred-stack-boundary=3
      support, because we test for it before setting -mno-sse.

      Fix it by reordering the Makefile bits.

      Compile-tested only.  This should help avoid code generation
      issues such as the one that was worked around in:

        b96fecbfa8c8 ("x86/fpu: Fix boot crash in the early FPU code")

      I'm a bit concerned that we could still have problems on older
      GCC versions given that our asm code does not respect GCC's idea
      of the ABI-required stack alignment.

      sfc: support for cascaded multicast filtering

      Recent versions of firmware for SFC9100 adapters add support for filter
       chaining, in which packets matching multiple filters are delivered to all
       filters' recipients, rather than only the highest match-priority filter 
as was
       previously the case.
      This patch series enables this feature and redesigns the filter handling 
code
       to make use of it; in particular, subscribing to a multicast address on 
one
       function no longer prevents traffic to that address reaching another 
function
       which is in promiscuous or allmulti mode.
      If the firmware does not support filter chaining, the driver will fall 
back to
       the old behaviour.

      sfc: support cascaded multicast filters

      If the workaround to support cascaded multicast filters 
("workaround_26807") is
      enabled, the broadcast filter and individual multicast filters are not 
inserted
      when in promiscuous or allmulti mode.

      There is a race while inserting and removing filters when entering and 
leaving
      promiscuous mode.  When changing promiscuous state with cascaded multicast
      filters, the old multicast filters are removed before inserting the new 
filters
      to avoid duplicating packets; this can lead to dropped packets until all
      filters have been inserted.

      The efx_nic:mc_promisc flag is added to record the presence of a multicast
      promiscuous filter; this gives a simple way to tell if the promiscuous 
state is
      changing.

      If a function is in promiscuous mode and another function has a broadcast

       multicast filter inserted, the function in promiscuous mode won't see 
that
       broadcast or multicast traffic.
      Most notably this breaks broadcast, which means ARP doesn't work. Less
       show-stoppingly, a function listening on a multicast address that's also 
in
       promiscuous mode will not see that multicast traffic if another function 
is
       also listening on that multicast address.

      sfc: warn if other functions have been reset by MCFW

      When enabling the workaround for cascaded multicast filters, the MC
       can reset other functions if they have already inserted filters.
       In that case, the workaround has been enabled, but print an info
       message in the log recording that other functions had to be reset.

      As other functions were reset, the MC will have incremented its boot
       count, so also increment the warm_boot_count on the function which
       enabled the workaround, as that function won't have received an MC
       reboot event and does not need to reset.

      sfc: enable cascaded multicast filters in MCFW

      After creating event queue 0, check to see if the workaround is enabled,
       and enable it if necessary.  This will be called during PCI probe and
       also when coming back up after a reset.  The nic_data->workaround_26807
       will be used in the future to control the filter insertion behaviour
       based on this workaround.

      Only the primary PF can enable this workaround, so tolerate an EPERM
       error and continue.  Otherwise, if any step in the checking and enabling
       of the workaround fails, the event queue must be removed.

      We check that workaround is implemented before trying to enable it,
       and store the current workaround setting before trying to change it.

      ext4: implement cgroup writeback support

      For ordered and writeback data modes, all data IOs go through
      ext4_io_submit.  This patch adds cgroup writeback support by invoking
      wbc_init_bio() from io_submit_init_bio() and wbc_account_io() in
      io_submit_add_bh().  Journal data which is written by jbd2 worker is
      left alone by this patch and will always be written out from the root
      cgroup.

      ext4_fill_super() is updated to set MS_CGROUPWB when data mode is
      either ordered or writeback.  In journaled data mode, most IOs become
      synchronous through the journal and enabling cgroup writeback support
      doesn't make much sense or difference.  Journaled data mode is left
      alone.

      Lightly tested with sequential data write workload.  Behaves as
      expected.

      This doesn't cause any noticeable differences now but having

      In commit d999297c3dbbe7fdd832f7fa4ec84301e170b3e6
      ("tipc: reduce locking scope during packet reception") we introduced

      so that it sometimes by error sends out a non-zero link priority value
      in created protocol messages.

      The bug may lead to an extra link reset at initial link establising
      with older nodes. This will never happen more than once, whereafter
      the link will work as intended.

and
        why this is required

      Initial cover letter from Stas:

      Hello.

      Currently the link status auto-negotiation is enabled
      for any SGMII link with fixed-link DT binding.
      The regression was reported:
      https://lkml.org/lkml/2015/7/8/865
      Apparently not all HW that implements SGMII protocol, generates the
      inband status for the auto-negotiation to work.
      More details here:
      https://lkml.org/lkml/2015/7/10/206

      The following patches reverts to the old behavior by default,
      which is to not enable the auto-negotiation for fixed-link.
      The new DT property is added that allows to explicitly request
      the auto-negotiation.

      mvneta: use inband status only when explicitly enabled

      The commit 898b2970e2c9 ("mvneta: implement SGMII-based in-band link state
      signaling") implemented the link parameters auto-negotiation 
unconditionally.
      Unfortunately it appears that some HW that implements SGMII protocol,
      doesn't generate the inband status, so it is not possible to 
auto-negotiate
      anything with such HW.

      This patch enables the auto-negotiation only if explicitly requested with
      the 'managed' DT property.

      This patch fixes the following regression:

      of_mdio: add new DT property 'managed' to specify the PHY management type

      Currently the PHY management type is selected by the MAC driver arbitrary.
      The decision is based on the presence of the "fixed-link" node and on a
      will of the driver's authors.
      This caused a regression recently, when mvneta driver suddenly started
      to use the in-band status for auto-negotiation on fixed links.
      It appears the auto-negotiation may not work when expected by the MAC 
driver.
      Sebastien Rannou explains:
      << Yes, I confirm that my HW does not generate an in-band status. AFAIK, 
it's
      a PHY that aggregates 4xSGMIIs to 1xQSGMII ; the MAC side of the PHY (with
      inband status) is connected to the switch through QSGMII, and in this 
context
      we are on the media side of the PHY. >>
      https://lkml.org/lkml/2015/7/10/206

      This patch introduces the new string property 'managed' that allows
      the user to set the management type explicitly.
      The supported values are:
      "auto" - default. Uses either MDIO or nothing, depending on the presence
      of the fixed-link node
      "in-band-status" - use in-band status

      net: phy: fixed_phy: handle link-down case

      fixed_phy_register() currently hardcodes the fixed PHY link to 1, and
      expects to find a "speed" parameter to provide correct information
      towards the fixed PHY consumer.

      In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band
      status auto-negotiation) fixed PHYs, none of these parameters can be
      provided since they will be auto-negotiated, hence, we just provide a
      zero-initialized fixed_phy_status to fixed_phy_register() which makes it
      fail when we call fixed_phy_update_regs() since status.speed = 0 which
      makes us hit the "default" label and error out.

      Without this change, we would also see potentially inconsistent
      speed/duplex parameters for fixed PHYs when the link is DOWN.

      net: dsa: bcm_sf2: Do not override speed settings

      The SF2 driver currently overrides speed settings for its port
      configured using a fixed PHY, this is both unnecessary and incorrect,
      because we keep feedback to the hardware parameters that we read from
      the PHY device, which in the case of a fixed PHY cannot possibly change
      speed.

      This is a required change to allow the fixed PHY code to allow
      registering a PHY with a link configured as DOWN by default and avoid
      some sort of circular dependency where we require the link_update
      callback to run to program the hardware, and we then utilize the fixed
      PHY parameters to program the hardware with the same settings.

      PCI: Add dev_flags bit to access VPD through function 0

      Add a dev_flags bit, PCI_DEV_FLAGS_VPD_REF_F0, to access VPD through
      function 0 to provide VPD access on other functions.  This is for hardware
      devices that provide copies of the same VPD capability registers in
      multiple functions.  Because the kernel expects that each function has its
      own registers, both the locking and the state tracking are affected by VPD
      accesses to different functions.

      On such devices for example, if a VPD write is performed on function 0,
      *any* later attempt to read VPD from any other function of that device 
will
      hang.  This has to do with how the kernel tracks the expected value of the
      F bit per function.

      Concurrent accesses to different functions of the same device can not only
      hang but also corrupt both read and write VPD data.

      When hangs occur, typically the error message:

        vpd r/w failed.  This is likely a firmware bug on this device.

      will be seen.

      Never set this bit on function 0 or there will be an infinite recursion.

      ====================
      Lightweight & flow based encapsulation

      This series combines the work previously posted by Roopa, Robert and
      myself. It's according to what we discussed at NFWS. The motivation
      of this series is to:

       * Consolidate code between OVS and the rest of the kernel and get
         rid of OVS vports and instead represent them as pure net_devices.
       * Introduce a lightweight tunneling mechanism which enables flow
         based encapsulation to improve scalability on both RX and TX.
       * Do the above in an encapsulation unspecific way so that the
         encapsulation type is eventually abstracted away from the user.
       * Use the same forwarding decision for both native forwarding and
         encapsulation thus allowing to switch between native IPv6 and
         UDP encapsulation based on endpoint without requiring additional
         logic

      The fundamental changes introduces in this series are:
       * A new RTA_ENCAP Netlink attribute for routes carrying encapsulation
         instructions. Depending on the specified type, the instructions
         apply to UDP encapsulations, MPLS and possible other in the future.
       * Depending on the encapsulation type, the output function of the
         dst is directly overwritten or the dst merely attaches metadata and
         relies on a subsequent net_device to apply it to the packet. The
         latter is typically used if an inner and outer IP header exist which
         require two subsequent routing lookups to be performed.
       * A new metadata_dst structure which can be attached to skbs to
         carry metadata in between subsystems. This new metadata transport
         is used to provide a single interface for VXLAN, routing and OVS
         to communicate through metadata.

      The OVS interfaces remain as-is but will transparently create a real
      VXLAN net_device in the background. iproute2 is extended with a new
      use cases:

        VXLAN:
        ip route add 40.1.1.1/32 encap vxlan id 10 dst 50.1.1.2 dev vxlan0

        MPLS:
        ip route add 10.1.1.0/30 encap mpls 200 via inet 10.1.1.1 dev swp1

      Performance implications:
        The additional memory allocation in the receive path should have
        performance implications although it is not observable in standard
        throughput tests if GRO is properly done. The correct net_device
        model outweights the additional cost of the allocation. Furthermore,
        this implication can be relaxed by reintroducing a direct unqueued
        path from a software device to a consumer like bridge or OVS if
        needed.

      vxlan: Flow based tunneling

      Allows putting a VXLAN device into a new flow-based mode in which
      skbs with a ip_tunnel_info dst metadata attached will be encapsulated
      according to the instructions stored in there with the VXLAN device
      defaults taken into consideration.

      Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is
      set, the packet processing will populate a ip_tunnel_info struct for
      each packet received and attach it to the skb using the new metadata
      dst.  The metadata structure will contain the outer header and tunnel
      header fields which have been stripped off. Layers further up in the
      stack such as routing, tc or netfitler can later match on these fields
      and perform forwarding. It is the responsibility of upper layers to
      ensure that the flag is set if the metadata is needed. The flag limits
      the additional cost of metadata collecting based on demand.

      This prepares the VXLAN device to be steered by the routing and other
      subsystems which allows to support encapsulation for a large number
      of tunnel endpoints and tunnel ids through a single net_device which
      improves the scalability.

      It also allows for OVS to leverage this mode which in turn allows for
      the removal of the OVS specific VXLAN code.

      Because the skb is currently scrubed in vxlan_rcv(), the attachment of
      the new dst metadata is postponed until after scrubing which requires
      the temporary addition of a new member to vxlan_metadata. This member
      is removed again in a later commit after the indirect VXLAN receive API
      has been removed.

      dst: Metadata destinations

      Introduces a new dst_metadata which enables to carry per packet metadata
      between forwarding and processing elements via the skb->dst pointer.

      The structure is set up to be a union. Thus, each separate type of
      metadata requires its own dst instance. If demand arises to carry
      multiple types of metadata concurrently, metadata dst entries can be
      made stackable.

      The metadata dst entry is refcnt'ed as expected for now but a non
      reference counted use is possible if the reference is forced before
      queueing the skb.

      In order to allow allocating dsts with variable length, the existing
      dst_alloc() is split into a dst_alloc() and dst_init() function. The
      existing dst_init() function to initialize the subsystem is being
      renamed to dst_subsys_init() to make it clear what is what.

      The check before ip_route_input() is changed to ignore metadata dsts
      and drop the dst inside the routing function thus allowing to interpret
      metadata in a later commit.

      ASoC: dapm: Avoid duplicating immutable strings

      When creating a new widget from a template the name string of the template
      is duplicated for the newly created widget. This is necessary because in
      some cases the string might be stored on the stack or other volatile
      memory locations.

      But most of the time the string is static const data, which means it is
      possible to use it directly without having to worry that it might get 
freed
      or changed.

      Use kstrdup_const() to handle duplicating the string. This function is
      capable of detecting whether a string is immutable and if it is returns 
the
      input without duplicating it. This will slightly reduce the runtime memory
      footprint of DAPM and also speed up initialization.

      mtd: m25p80: allow arbitrary OF matching for "jedec,spi-nor"

      When we added the "jedec,spi-nor" compatible string for use in this
      driver, we added it as a modalias option. The modalias can be derived in
      different ways for platform devices vs. device tree (of_*) matching. But
      for device tree matching (the primary target of this identifier string),
      the modalias is determined from the first entry in the 'compatible'
      property. IOW, the following properties would bind to this driver:

        // Option (a), modalias = "spi-nor"
        compatible = "jedec,spi-nor";

        // Option (b), modalias = "spi-nor"
        compatible = "idontknowwhatimdoing,spi-nor";

      But the following would not:

        // Option (c), modalias = "shinynewdevice"
        compatible = "myvendor,shinynewdevice", "jedec,spi-nor";

      So, we'd like to match (a) and (c) (even when we don't have an explicit
      entry for "shinynewdevice"), and we'd rather not allow (b).

      To do this, we
        (1) always (for devices without specific platform data) pass the
            modalias to the spi-nor library;
        (2) rework the spi-nor library to not reject "bad" names, and
            instead just fall back to autodetection; and
        (3) add the .of_match_table to properly catch all "jedec,spi-nor".

      This allows (a) and (c) without warnings, and rejects (b).

      regulator: rk808: make better use of the gpiod API

      The gpiod functions include variants for managed gpiod resources. Use it
      to simplify the remove function.

      As the driver handles a device node without a specification of dvs gpios
      just fine, additionally use the variant of gpiod_get exactly for this
      use case. This makes error checking more strict.

      As a third benefit this patch makes the driver use the flags parameter
      of gpiod_get* which will not be optional any more after 4.2 and so
      prevents a build failure when the respective gpiod commit is merged.

      NVMe: Use CMB for the IO SQes if available

      Some controllers have a controller-side memory buffer available for use
      for submissions, completions, lists, or data.

      If a CMB is available, the entire CMB will be ioremapped and it will
      attempt to map the IO SQes onto the CMB. The queues will be shrunk as
      needed. The CMB will not be used if the queue depth is shrunk below some
      threshold where it may have reduced performance over a larger queue
      in system memory.

      NVMe: Unify SQ entry writing and doorbell ringing

      This patch changes sq_cmd writers to instead create their command on
      the stack. __nvme_submit_cmd copies the sq entry to the queue and writes
      the doorbell.

      PCI: xilinx: Check for MSI interrupt flag before handling as INTx

      Occasionally both MSI and INTx bits in the interrupt decode register are
      set at once by the Xilinx AXI PCIe Bridge, so the MSI flag in the 
interrupt
      message should be checked to ensure that the correct handler is used.

      If this check is not in place and the interrupt message type is MSI, the
      INTx handler will be used erroneously when both type bits are set.  This
      will also be followed by a second read of the message FIFO, which can
      result in the function returning early and the interrupt decode register
      not being cleared if the FIFO is now empty.

      While changing interface type from p2p client or p2p go to

      iwlegacy: convert hex_dump_to_buffer() to %*ph

      There is no need to use hex_dump_to_buffer() in the cases like this:

        hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);      /* len 
<= 16 */
        sprintf("%s\n", outbuf);

      since it maybe easily converted to simple:

        sprintf("%*ph\n", len, buf);

      Note: it seems in the case the output is groupped by 2 bytes and looks 
like a
      typo. Thus, patch changes that to plain byte stream.

      collision entropy, and directly measured min-entropy. Just to
      be conservative, we recommend the estimated min-Entropy to be

      brcmfmac: set wiphy's addresses to provide valid MACs

      Broadcom's firmware requires every BSS to use MAC address with unique
      last few bits. The amount of bits may depend on a particular firmware,
      it was verified to be 2 for BCM43602 one.
      If this condition won't be fulfilled firmware will reject such MAC:
      brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52

      We don't want to simply set addr_mask as it would also disallow using
      locally administrated bit. Instead let's build a list of addresses
      manually enabling 0x2 bit for extra interfaces.

      ath9k: fix moredata flag endianness in cabq tx

      While compiling ath9k with some extra flags I've
      found that:

       ath9k/xmit.c +2473 ## 16: warning: restricted __le16 degrades to integer
       ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &=
       ath9k/xmit.c +2474 ## 36:    left side has type restricted __le16
       ath9k/xmit.c +2474 ## 36:    right side has type int

      There's no way for frame ftype/stype to be
      mistreated as the offending 'moredata' flag when
      considering cab queue.

      This could've however theoretically led sometimes
      to increased power consumption on connected
      stations as they would keep their Rx active
      waiting for frames that would never come.

      mwifiex: fix for p2p broken link

      This patch fixes following issues in p2p code paths.

      1) bss role, bss type and connection type was not set correctly
      for p2p GO and p2p client at couple of places.
      2) Driver appends a proprietary header to management frames
      which will be parsed by our firmware. Later while informing
      TX status to cfg80211, modified frame buffer was passed to
      cfg80211_mgmt_tx_status() instead of original one.

      ath9k: make DMA stop related messages debug-only

      A long time ago, ath9k had issues during reset where the DMA engine
      would stay active and could potentially corrupt memory.
      To debug those issues, the driver would print warnings whenever they
      occur.

      Nowadays, these issues are gone and the primary cause of these messages
      is if the MAC is stuck during reset or busy processing a long
      transmission. This is fairly harmless, yet these messages continue to
      worry users.

      To reduce the number of bogus bug reports, turn these messages into
      debug messages and count their occurence in the "reset" debugfs file.

      mwifiex: usb: Fix double add error when submitting rx urb

      There is an error that can occur where the driver adds the same URB to 
USB submission list twice.
      This happens since mwifiex_usb_submit_rem_rx can submit packets at same 
time as an rx urb complete callback.
      This causes list corruption and is fixed by not setting the skb to NULL 
when submitting an rx packet.

      drm/i915: remove unnecessary null test

      While creating the debugfs file we are setting the inode->i_private to
      dev. That same dev is passed to these functions as private of struct
      seq_file via single_open(). Moreover single_open is setting
      file->private_data->private to dev.
      So at this point it can never be NULL.

      mwifiex: avoid freeing improper pointer in mwifiex_set_wowlan_mef_entry

      mwifiex_set_wowlan_mef_entry attempts to free a passed-in pointer in
      case of an error.  The only caller (mwifiex_set_mef_filter) passes that
      pointer as an offset into allocated memory, so any attempt to free that
      will not be the actual allocated pointer.

      Address this by changing mwifiex_set_wowlan_mef_entry to not do any
      free, and to cause mwifiex_set_mef_filter to do the appropriate free if
      the call to mwifiex_set_wowlan_mef_entry fails.

      KVM: arm64: guest debug, HW assisted debug support

      This adds support for userspace to control the HW debug registers for
      guest debug. In the debug ioctl we copy an IMPDEF registers into a new
      register set called host_debug_state.

      We use the recently introduced vcpu parameter debug_ptr to select which
      register set is copied into the real registers when world switch occurs.

      I've made some helper functions from hw_breakpoint.c more widely
      available for re-use.

      As with single step we need to tweak the guest registers to enable the
      exceptions so we need to save and restore those bits.

      Two new capabilities have been added to the KVM_EXTENSION ioctl to allow
      userspace to query the number of hardware break and watch points
      available on the host hardware.

      KVM: arm64: introduce vcpu->arch.debug_ptr

      This introduces a level of indirection for the debug registers. Instead
      of using the sys_regs[] directly we store registers in a structure in
      the vcpu. The new kvm_arm_reset_debug_ptr() sets the debug ptr to the
      guest context.

      Because we no longer give the sys_regs offset for the sys_reg_desc->reg
      field, but instead the index into a debug-specific struct we need to
      add a number of additional trap functions for each register. Also as the
      generic generic user-space access code no longer works we have
      introduced a new pair of function pointers to the sys_reg_desc structure
      to override the generic code when needed.

      KVM: arm64: re-factor hyp.S debug register code

      This is a pre-cursor to sharing the code with the guest debug support.
      This replaces the big macro that fishes data out of a fixed location
      with a more general helper macro to restore a set of debug registers. It
      uses macro substitution so it can be re-used for debug control and value
      registers. It does however rely on the debug registers being 64 bit
      aligned (as they happen to be in the hyp ABI).

      KVM: arm64: guest debug, add support for single-step

      This adds support for single-stepping the guest. To do this we need to
      manipulate the guests PSTATE.SS and MDSCR_EL1.SS bits to trigger
      stepping. We take care to preserve MDSCR_EL1 and trap access to it to
      ensure we don't affect the apparent state of the guest.

      As we have to enable trapping of all software debug exceptions we
      suppress the ability of the guest to single-step itself. If we didn't we
      would have to deal with the exception arriving while the guest was in
      kernelspace when the guest is expecting to single-step userspace. This
      is something we don't want to unwind in the kernel. Once the host is no
      longer debugging the guest its ability to single-step userspace is
      restored.

      KVM: arm64: guest debug, add SW break point support

      This adds support for SW breakpoints inserted by userspace.

      We do this by trapping all guest software debug exceptions to the
      hypervisor (MDCR_EL2.TDE). The exit handler sets an exit reason of
      KVM_EXIT_DEBUG with the kvm_debug_exit_arch structure holding the
      exception syndrome information.

      It will be up to userspace to extract the PC (via GET_ONE_REG) and
      determine if the debug event was for a breakpoint it inserted. If not
      userspace will need to re-inject the correct exception restart the
      hypervisor to deliver the debug exception to the guest.

      Any other guest software debug exception (e.g. single step or HW
      assisted breakpoints) will cause an error and the VM to be killed. This
      is addressed by later patches which add support for the other debug
      types.

      KVM: arm: introduce kvm_arm_init/setup/clear_debug

      This is a precursor for later patches which will need to do more to
      setup debug state before entering the hyp.S switch code. The existing
      functionality for setting mdcr_el2 has been moved out of hyp.S and now
      uses the value kept in vcpu->arch.mdcr_el2.

      As the assembler used to previously mask and preserve MDCR_EL2.HPMN I've
      had to add a mechanism to save the value of mdcr_el2 as a per-cpu
      variable during the initialisation code. The kernel never sets this
      number so we are assuming the bootcode has set up the correct value
      here.

      This also moves the conditional setting of the TDA bit from the hyp code
      into the C code which is currently used for the lazy debug register
      context switch code.

      drivers/video/fbdev/atyfb: Use arch_phys_wc_add() and ioremap_wc()

      This driver uses strong UC for the MMIO region, and ioremap_wc()
      for the framebuffer to whitelist for the WC MTRR that can be
      changed to WC. On PAT systems we don't need the MTRR call so
      just use arch_phys_wc_add() there, this lets us remove all those
      ifdefs. Let's also be consistent and use ioremap_wc() for ATARI
      as well.

      There are a few motivations for this:

        a) Take advantage of PAT when available.

        b) Help bury MTRR code away, MTRR is architecture specific and
           on x86 it is being replaced by PAT.

        c) Help with the goal of eventually using _PAGE_CACHE_UC over
           _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
           de33c442e titled "x86 PAT: fix performance drop for glx,
           use UC minus for ioremap(), ioremap_nocache() and
           pci_mmap_page_range()").

      The conversion done is expressed by the following Coccinelle
      SmPL patch, it additionally required manual intervention to
      address all the ifdeffery and removal of redundant things which
      arch_phys_wc_add() already addresses such as verbose message
      about when MTRR fails and doing nothing when we didn't get an
      MTRR:

      drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC

      Replace a WC MTRR call followed by a UC MTRR "hole" call with a
      single WC MTRR call and use strong UC to protect the MMIO region
      and account for the device's architecture and MTRR size
      requirements.

      The atyfb driver relies on two overlapping MTRRs. It does this
      to account for the fact that, on some devices, it has the MMIO
      region bundled together with the framebuffer on the same PCI BAR
      and the hardware requirement on MTRRs on both base and size to
      be powers of two.

      In the worst case, the PCI BAR is of 16 MiB while the MMIO
      region is on the last 4 KiB of the same PCI BAR. If we use just
      one MTRR for WC, we can only end up with an 8 MiB or 16 MiB
      framebuffer. Using a 16 MiB WC framebuffer area is unacceptable
      since we need the MMIO region to not be write-combined. An 8 MiB
      WC framebuffer option does not let use quite a bit of
      framebuffer space, it would reduce the resolution capability of
      the device considerably.

      An alternative is to use many MTRRs but on some systems that
      could mean not having enough MTRRs to cover the framebuffer. The
      current solution is to issue a 16 MiB WC MTRR followed by a 4
      KiB UC MTRR on the last 4 KiB. Its worth mentioning and
      documenting that the current ioremap*() strategy as well: the
      first ioremap() is used only for the MMIO region, a second
      ioremap() call is used for the framebuffer *and* the MMIO
      region, the MMIO region then ends up mmapped twice.

      Two ioremap() calls are used since in some situations the
      framebuffer actually ends up on a separate auxiliary PCI BAR,
      but this is not always true. In the worst case, the PCI BAR is
      shared for both MMIO and the framebuffer. By allowing
      overlapping ioremap() calls, the driver enables two types of
      devices with one simple ioremap() strategy.

      See also:

        2f9e897353fc ("x86/mm/mtrr, pat: Document Write Combining MTRR type 
effects on PAT / non-PAT pages")

      By default, Linux today defaults both pci_mmap_page_range() and
      ioremap_nocache() to use _PAGE_CACHE_MODE_UC_MINUS. On x86,
      ioremap() aliases ioremap_nocache(). The preferred value for
      Linux may soon change, however, the goal is to use
      _PAGE_CACHE_MODE_UC by default in the future.

      We can use ioremap_uc() to set PCD=1, PWT=1 on non-PAT systems
      and use a PAT value of UC for PAT systems. This will ensure the
      same settings are in place regardless of what Linux decides to
      use by default later and to not regress our MTRR strategy since
      the effective memory type will differ depending on the value
      used. Using a WC MTRR on such an area will be nullified. This
      technique can be used to protect the MMIO region in this
      driver's case and address the restrictions of the device's
      architecture as well as restrictions set upon us by powers of 2
      when using MTRRs.

      This allows us to replace the two MTRR calls with a single 16
      MiB WC MTRR and use page-attribute settings for non-PAT and PAT
      entry values for PAT systems to ensure the appropriate effective
      memory type won't have a write-combining effect on the MMIO
      region on both non-PAT and PAT systems. The framebuffer area
      will be sure to get the write-combined effective memory type by
      white-listing it with ioremap_wc().

      We ensure the desired effective memory types are set by:

      0) Using one ioremap_uc() for the MMIO region alone.
         This will set the page attribute settings for the MMIO
         region to PCD=1, PWT=1 for non-PAT systems while using a
         strong UC value on PAT systems.

      1) Fixing the framebuffer ioremapped area to exclude the
         MMIO region and using ioremap_wc() instead to whitelist
         the area we want for write-combining.

      In both cases, an implementation defined (as per 2f9e897353fc)
      effective memory type of WC is used for the framebuffer for
      non-PAT systems.

      drivers/video/fbdev/atyfb: Clarify ioremap() base and length used

      Adjust the ioremap() call for the framebuffer to use the same
      values we later use for the framebuffer. This will make it
      easier to review the next change.

      The size of the framebuffer varies but since this is for PCI we
      *know* this defaults to 0x800000. atyfb_setup_generic() is
      *only* used on PCI probe.

      No functional change.

      x86/mm, asm-generic: Add IOMMU ioremap_uc() variant default

      We currently have no safe way of currently defining architecture
      agnostic IOMMU ioremap_*() variants. The trend is for folks to
      *assume* that ioremap_nocache() should be the default everywhere
      and then add this mapping on each architectures -- this is not
      correct today for a variety of reasons.

      We have two options:

        1) Sit and wait for every architecture in Linux to get a
           an ioremap_*() variant defined before including it upstream.

        2) Gather consensus on a safe architecture agnostic ioremap_*()
           default.

      Approach 1) introduces development latencies, and since 2) will
      take time and work on clarifying semantics the only remaining
      sensible thing to do to avoid issues is returning NULL on
      ioremap_*() variants.

      In order for this to work we must have all architectures declare
      their own ioremap_*() variants as defined. This will take some
      work, do this for ioremp_uc() to set the example as its only
      currently implemented on x86. Document all this.

      We only provide implementation support for ioremap_uc() as the
      other ioremap_*() variants are well defined all over the kernel
      for other architectures already.

      x86/kconfig/32: Rename CONFIG_VM86 and default it to 'n'

      VM86 is entirely broken if ptrace, syscall auditing, or
      NOHZ_FULL is in use.  The code is a big undocumented mess, it's
      a real PITA to test, and it looks like a big chunk of vm86_32.c
      is dead code.  It also plays awful games with the entry asm.

      No one should be using it anyway. Use DOSBOX or KVM instead.

      Let's accelerate its slow death.  Remove it from EXPERT and
      default it to n.  Distros should not enable it.  In the unlikely
      event that some user needs it, they can easily re-enable it.

      While we're at it, rename it to CONFIG_X86_LEGACY_VM86 so that 'make
      oldconfig' users will be prompted again.  I left CONFIG_VM86 as
      an alias to avoid a treewide replacement of the names.  We can
      clean that up once the current asm and vm86 code churn settles
      down.

      locking/spinlocks: Force inlining of spinlock ops

      With both gcc 4.7.2 and 4.9.2, sometimes GCC mysteriously
      doesn't inline very small functions we expect to be inlined.
      See:

          https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66122

      In particular, with this config:

         http://busybox.net/~vda/kernel_config

      there are more than a thousand copies of tiny spinlock-related
      functions:

        $ nm --size-sort vmlinux | grep -iF ' t ' | uniq -c | grep -v '^ *1 ' | 
sort -rn | grep ' spin'
          473 000000000000000b t spin_unlock_irqrestore
          292 000000000000000b t spin_unlock
          215 000000000000000b t spin_lock
          134 000000000000000b t spin_unlock_irq
          130 000000000000000b t spin_unlock_bh
          120 000000000000000b t spin_lock_irq
          106 000000000000000b t spin_lock_bh

      Disassembly:

       ffffffff81004720 <spin_lock>:
       ffffffff81004720:       55                      push   %rbp
       ffffffff81004721:       48 89 e5                mov    %rsp,%rbp
       ffffffff81004724:       e8 f8 4e e2 02          callq <_raw_spin_lock>

       ffffffff8100472a:       c3                      retq

      This patch fixes this via s/inline/__always_inline/ in
      spinlock.h. This decreases vmlinux by about 40k:

      x86/entry/syscalls: Wire up 32-bit direct socket calls

      On x86_64, there's no socketcall syscall; instead all of the
      socket calls are real syscalls.  For 32-bit programs, we're
      stuck offering the socketcall syscall, but it would be nice to
      expose the direct calls as well.  This will enable seccomp to
      filter socket calls (for new userspace only, but that's fine for
      some applications) and it will provide a tiny performance boost.

      drm/i915: Add provision to extend Golden context batch

      The Golden batch carries 3D state at the beginning so that HW starts with
      a known state. It is carried as a binary blob which is auto-generated from
      source. The idea was it would be easier to maintain and keep the 
complexity
      out of the kernel which makes sense as we don't really touch it. However 
if
      you really need to update it then you need to update generator source and
      keep the binary blob in sync with it.

      There is a need to patch this in bxt to send one additional command to 
enable
      a feature. A solution was to patch the binary data with some additional
      data structures (included as part of auto-generator source) but it was
      unnecessarily complicated.

      Chris suggested the idea of having a secondary batch and execute two batch
      buffers. It has clear advantages as we needn't touch the base golden 
batch,
      can customize secondary/auxiliary batch depending on Gen and can be 
carried
      in the driver with no dependencies.

      This patch adds support for this auxiliary batch which is inserted at the
      end of golden batch and is completely independent from it. Thanks to Mika
      for the preliminary review.

      v2: Strictly conform to the batch size requirements to cover Gen2 and
      add comments to clarify overflow check in macro (Chris, Mika).

      v3: aux_batch_offset was declared as u64, change it to u32 (Chris)

       - split out the refactoring from the fix itself
       - Doing a full reverse routing as in v1 is not necessary. Only looking
         for the interface that has the address and comparing its number is
         enough.

      sctp: fix src address selection if using secondary addresses

      In short, sctp is likely to incorrectly choose src address if socket is
      bound to secondary addresses. This patch fixes it by adding a new check
      that checks if such src address belongs to the interface that routing
      identified as output.

      This is enough to avoid rp_filter drops on remote peer.

      Details:

      Currently, sctp will do a routing attempt without specifying the src
      address and compare the returned value (preferred source) with the
      addresses that the socket is bound to. When using secondary addresses,
      this will not match.

      Then it will try specifying each of the addresses that the socket is
      bound to and re-routing, checking if that address is valid as src for
      that dst. Thing is, this check alone is weak:

          cache

      Even if you specify an interface:

      # ip r g 192.168.100.193 from 192.168.122.148 oif eth1
      192.168.100.193 from 192.168.122.148 dev eth1
          cache

      Although this would be valid, peers using rp_filter will drop such
      packets as their src doesn't match the routes for that interface.

      drm/i915: Add GuC-related header files

      intel_guc_fwif.h contains the subset of the GuC interface that we
      will need for submission of commands through the GuC. These MUST
      be kept in sync with the definitions used by the GuC firmware, and
      updates to this file will (or should) be autogenerated from the
      source files used to build the firmware. Editing this file is
      therefore not recommended.

      i915_guc_reg.h contains definitions of GuC-related hardware:
      registers, bitmasks, etc. These should match the BSpec.

      sched/idle: Move latency tracing stop/start calls deeper inside the idle 
loop

      Make sure to stop tracing only once we are past a point where
      all latency tracing events have been processed (irqs are not
      enabled again). This has the slight advantage of capturing more
      latency related events in the idle path, but most importantly it
      makes sure that latency tracing doesn't get re-enabled
      inadvertently when new events are coming in.

      This makes the irqsoff latency tracer useful again, as we stop
      capturing CPU sleep time as IRQ latency.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      New features:

        - Allow filtering out of perf's PID via 'perf record --exclude-perf'. 
(Wang Nan)

        - 'perf trace' now supports syscall groups, like strace, i.e:

            $ trace -e file touch file

          Will expand 'file' into multiple, file related, syscalls. More work 
needed to
          add extra groups for other syscall groups, and also to complement 
what was
          added for the 'file' group, included as a proof of concept. (Arnaldo 
Carvalho de Melo)

        - Add lock_pi stresser to 'perf bench futex', to test the kernel code
          related to FUTEX_(UN)LOCK_PI. (Davidlohr Bueso)

      User visible fixes:

        - Apply --filter to all events in a glob matching, not just the last 
one. (Wang Nan)

      Documentation changes:

        - Document setting '-e pmu/period=N/' in the 'perf record' man page. 
(Kan Liang)

      Infrastructure changes:

        - 'perf probe' code simplifications and movements to separate files. 
(Masami Hiramatsu)

        - Fix makefile generation under 'dash'. (Sergei Trofimovich)

      Resulting in inconsistent energy policy settings across CPUs.

      This register is set via init_intel() at bootup. During resume,
      the secondary CPUs are brought online again and init_intel() is
      callled which re-initializes the register. The boot CPU however
      never reinitializes the register.

      Add a syscore callback to reinitialize the register for the boot CPU.

      ARM: dts: Extend exynos5420-pinctrl nodes using labels instead of paths

      A previously defined Device Tree node, can be extended either by defining
      a node using the same full path or by creating a label for the node and
      referencing to it.

      Using full paths is more error prone since if there was a typo error, a
      new node will be created instead of extending the node as it was desired.
      This will lead to run-time errors that could be hard to detect.

      A mistyped label on the other hand, will cause a dtc compile error which
      makes it easier to detect the mistake since happens at build-time instead.

      The dtc compiler combines all the defined nodes that have the same path

      before the pinctrl device nodes are actually defined, the definition of
      the pinctrl device nodes happens in exynos5420-pinctrl.dtsi and are
      extended in exynos5420.dtsi.

      That is the opposite of the original intention so even when there is no
      difference in practice, the exynos5420-pinctrl.dtsi include should be
      moved at the end of the exynos5420.dtsi file after the pinctrl device
      nodes have been already defined.

      This will also allow to later change the exynos5420-pinctrl.dtsi file
      to use labels instead of full paths to extend the pinctrl nodes. Since
      keeping the include at the top, would cause a dtc build error due the
      pinctrl labels not being defined yet.

      improve accuracy of timing in test_bpf and add two stress tests:
      - {skb->data[0], get_smp_processor_id} repeated 2k times
      - {skb->data[0], vlan_push} x 68 followed by {skb->data[0], vlan_pop} x 68

      1st test is useful to test performance of JIT implementation of BPF_LD_ABS
      together with BPF_CALL instructions.
      2nd test is stressing skb_vlan_push/pop logic together with skb->data 
access
      via BPF_LD_ABS insn which checks that re-caching of skb->data is done 
correctly.

      In order to call bpf_skb_vlan_push() from test_bpf.ko have to add
      three export_symbol_gpl.

      bpf: introduce bpf_skb_vlan_push/pop() helpers

      Allow eBPF programs attached to TC qdiscs call skb_vlan_push/pop via
      helper functions. These functions may change skb->data/hlen which are
      cached by some JITs to improve performance of ld_abs/ld_ind instructions.
      Therefore JITs need to recognize bpf_skb_vlan_push/pop() calls,
      re-compute header len and re-cache skb->data/hlen back into cpu registers.
      Note, skb->data/hlen are not directly accessible from the programs,
      so any changes to skb->data done either by these helpers or by other
      TC actions are safe.

      eBPF JIT supported by three architectures:
      - arm64 JIT is using bpf_load_pointer() without caching, so it's ok as-is.
      - x64 JIT re-caches skb->data/hlen unconditionally after vlan_push/pop 
calls
        (experiments showed that conditional re-caching is slower).
      - s390 JIT falls back to interpreter for now when bpf_skb_vlan_push() is 
present
        in the program (re-caching is tbd).

      These helpers allow more scalable handling of vlan from the programs.
      Instead of creating thousands of vlan netdevs on top of eth0 and attaching
      TC+ingress+bpf to all of them, the program can be attached to eth0 
directly
      and manipulate vlans as necessary.

      Intel Wired LAN Driver Updates 2015-07-17

      This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
      freescale, siena and dp83640.

      Jacob provides several patches to clarify the intended way to implement
      both SIOCSHWTSTAMP and ethtool's get_ts_info().  It is okay to support
      the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
      filters.

      Alex Duyck provides a igb patch to pull the time stamp from the fragment
      before it gets added to the skb, to avoid a possible issue in which the
      fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
      being pulled after the copybreak check.  Also provides a ixgbevf patch to
      fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
      the advantage that the fragment does not have to be modified after it is
      added to the skb.

      Fan provides patches for ixgbe/ixgbevf to set the receive hash type
      based on receive descriptor RSS type.

      Todd provides a fix for igb where on check for link on any media other
      than copper was not being detected since it was looking on the incorrect
      PHY page (due to the page being used gets switched before the function
      to check link gets executed).

      net: bcmgenet: PHY initialization rework

      This patch series reworks how we perform PHY initialization and resets in 
the
      GENET driver. Although this contains mostly fixes, some of the changes 
are a
      bit too intrusive to be backported to 'net' at the moment.

      Some of the motivations behind these changes were to reduce the time 
spent in how
      performing MDIO transactions, since it is better to perform then when we 
have
      interrupts enabled. This reduces the bring-up time of GENET from ~600 
msecs down
      to ~8 msecs, and about the same time for suspend/resume.

      Since I do not currently have a system which is not DT-aware, can you 
(Petri,
      Jaedon) give this a try and confirm things keep working as expected?

      net: bcmgenet: Delay PHY initialization to bcmgenet_open()

      We are currently doing a full PHY initialization and even starting the
      pHY state machine during bcmgenet_mii_init() which is executed in the
      driver's probe function. This is convenient to determine whether we can
      attach to a proper PHY device but comes at the expense of spending up to
      10ms per MDIO transactions (to reach the waitqueue timeout), which slows
      things down.

      This also creates a sitaution where we end-up attaching twice to the
      PHY, which is not quite correct either.

      Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
      its error path accordingly.

      Avoid printing the message "attached PHY at address 1 [...]" every time
      we bring up/down the interface and remove this print since it duplicates
      what the PHY driver already does for us.

      net: bcmgenet: Determine PHY type before scanning MDIO bus

      Our internal GPHY might be powered off before we attempt scanning the
      MDIO bus and bind a driver to it. The way we are currently determining
      whether a PHY is internal or not is done *after* we have successfully
      matched its driver. If the PHY is powered down, it will not respond to
      the MDIO bus, so we will not be able to bind a driver to it.

      Our Device Tree for GENET interfaces specifies a "phy-mode" value:
      "internal" which tells if this internal uses an internal PHY or not.

      If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
      additional manual lookup, and if we find "internal" set the
      corresponding internal variable accordingly.

      Replace all uses of phy_is_internal() with a check against
      priv->internal_phy to avoid having to rely on whether or not
      priv->phydev is set correctly.

      net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()

      We are currently disabling the GPHY interface during bcmgenet_close(),
      and attempting to power it back on during bcmgenet_open(). This works
      fine for the first time, because we called bcmgenet_mii_config() which
      took care of enabling the interface, however, bcmgenet_power_up() really
      needs to power on the GPHY for correctness.

      This will be particularly important as we want to move
      bcmgenet_mii_probe() down to bcmgenet_open() to avoid seeing the "PHY
      already attached" message.

      net: bcmgenet: Remove excessive PHY reset

      We are currently issuing multiple PHY resets during a suspend/resume,
      first during bcmgenet_power_up() which does a hardware reset, then a
      software reset by calling bcmgenet_mii_reset(). This is both unnecessary
      and can take as long as 10ms per MDIO transactions while we re-apply
      workarounds because we do not yet have MDIO interrupts enabled.

      phy_resume() takes care of re-apply our workarounds in case we need any,
      and bcmgenet_power_up() does a PHY hardware reset, all of this is more
      than enough to guarantee that the PHY operates correctly.

      Joachim Eastwood says:

      ====================
      stmmac clean up for 4.3 part1

      This patch set continues the conversion of the dwmac glue layers
      to more proper platform drivers. The first part of the patch set
      cleans up stmmac_platform a bit. Refactors code from the common
      probe function and exports two functions that will be used in
      the dwmac-* drivers.

      Second part converts two simple dwmac-* drivers to have their
      own probe function and use the exported functions. This brings
      us closer to point where stmmac_platform is only a library of
      common functions for the dwmac-* drivers to use.

      The plan next is:
       * add probe functions to the rest of the dwmac-* drivers
       * move probe function in stmmac_platform to dwmac-generic
       * remove struct stmmac_of_data and let those drivers
         that actually need match data handle it themselves
       * clean up include/linux/stmmac.h

      Note that this patch set has only been tested on lpc18xx so
      testing on other platforms is greatly appreciated.

      stmmac: clean up platform/of_match data retrieval

      Refactor code to clearly separate probing non-dt versus dt. In the

      For dt the platform data structure is created and match data is
      copied into it. Note that support for supplying platform data in
      dt from AUXDATA is dropped as no users in mainline does this.

      tipc: reduce locking scope during packet reception

      We convert packet/message reception according to the same principle
      we have been using for message sending and timeout handling:

      We move the function tipc_rcv() to node.c, hence handling the initial
      packet reception at the link aggregation level. The function grabs
      the node lock, selects the receiving link, and accesses it via a new
      call tipc_link_rcv(). This function appends buffers to the input
      queue for delivery upwards, but it may also append outgoing packets
      to the xmit queue, just as we do during regular message sending. The
      latter will happen when buffers are forwarded from the link backlog,
      or when retransmission is requested.

      Upon return of this function, and after having released the node lock,
      tipc_rcv() delivers/tranmsits the contents of those queues, but it may
      also perform actions such as link activation or reset, as indicated by
      the return flags from the link.

      This reduces the number of cpu cycles spent inside the node spinlock,
      and reduces contention on that lock.

      tipc: introduce node contact FSM

      The logics for determining when a node is permitted to establish
      and maintain contact with its peer node becomes non-trivial in the
      presence of multiple parallel links that may come and go independently.

      A known failure scenario is that one endpoint registers both its links
      to the peer lost, cleans up it binding table, and prepares for a table
      update once contact is re-establihed, while the other endpoint may
      see its links reset and re-established one by one, hence seeing
      no need to re-synchronize the binding table. To avoid this, a node
      must not allow re-establishing contact until it has confirmation that
      even the peer has lost both links.

      Currently, the mechanism for handling this consists of setting and
      resetting two state flags from different locations in the code. This
      solution is hard to understand and maintain. A closer analysis even
      reveals that it is not completely safe.

      In this commit we do instead introduce an FSM that keeps track of
      the conditions for when the node can establish and maintain links.
      It has six states and four events, and is strictly based on explicit
      knowledge about the own node's and the peer node's contact states.
      Only events leading to state change are shown as edges in the figure
      below.

      tipc: move link supervision timer to node level

      In our effort to move control of the links to the link aggregation
      layer, we move the perodic link supervision timer to struct tipc_node.
      The new timer is shared between all links belonging to the node, thus
      saving resources, while still kicking the FSM on both its pertaining
      links at each expiration.

      The current link timer and corresponding functions are removed.

      The new function  makes use of the new FSM function introduced in the

      It returns an event bit field and potentially a link protocol packet
      to the caller.

      The existing timer function, link_timeout(), is still needed for a
      while, so we redesign it to become a wrapper around the new function.

      tipc: improve link FSM implementation

      The link FSM implementation is currently unnecessarily complex.
      It sometimes checks for conditional state outside the FSM data
      before deciding next state, and often performs actions directly
      inside the FSM logics.

      In this commit, we create a second, simpler FSM implementation,
      that as far as possible acts only on states and events that it is
      strictly defined for, and postpone any actions until it is finished
      with its decisions. It also returns an event flag field and an a
      buffer queue which may potentially contain a protocol message to
      be sent by the caller.

      Unfortunately, we cannot yet make the FSM "clean", in the sense
      that its decisions are only based on FSM state and event, and that
      state changes happen only here. That will have to wait until the
      activate/reset logics has been cleaned up in a future commit.

      We also rename the link states as follows:

      WORKING_WORKING -> TIPC_LINK_WORKING
      WORKING_UNKNOWN -> TIPC_LINK_PROBING
      RESET_UNKNOWN   -> TIPC_LINK_RESETTING
      RESET_RESET     -> TIPC_LINK_ESTABLISHING

      The existing FSM function, link_state_event(), is still needed for
      a while, so we redesign it to make use of the new function.

      tipc_link_build_proto_msg(). Instead of actually sending the created
      protocol message, it only creates it and adds it to the head of a
      skb queue provided by the caller.

      Since we still need the existing function tipc_link_protocol_xmit()
      for a while, we redesign it to make use of the new function.

      tipc: clean up definitions and usage of link flags

      The status flag LINK_STOPPED is not needed any more, since the
      mechanism for delayed deletion of links has been removed.
      Likewise, LINK_STARTED and LINK_START_EVT are unnecessary,
      because we can just as well start the link timer directly from
      inside tipc_link_create().

      We eliminate these flags in this commit.

      Instead of the above flags, we now introduce three new link modes,
      TIPC_LINK_OPEN, TIPC_LINK_BLOCKED and TIPC_LINK_TUNNEL. The values
      indicate whether, and in the case of TIPC_LINK_TUNNEL, which, messages
      the link is allowed to receive in this state. TIPC_LINK_BLOCKED also
      blocks timer-driven protocol messages to be sent out, and any change
      to the link FSM. Since the modes are mutually exclusive, we convert
      them to state values, and rename the 'flags' field in struct tipc_link
      to 'exec_mode'.

      Finally, we move the #defines for link FSM states and events from link.h
      into enums inside the file link.c, which is the real usage scope of
      these definitions.

      tipc: make media xmit call outside node spinlock context

      Currently, message sending is performed through a deep call chain,
      where the node spinlock is grabbed and held during a significant
      part of the transmission time. This is clearly detrimental to
      overall throughput performance; it would be better if we could send
      the message after the spinlock has been released.

      In this commit, we do instead let the call revert on the stack after
      the buffer chain has been added to the transmission queue, whereafter
      clones of the buffers are transmitted to the device layer outside the
      spinlock scope.

      As a further step in our effort to separate the roles of the node
      and link entities we also move the function tipc_link_xmit() to
      node.c, and rename it to tipc_node_xmit().

      tipc: change sk_buffer handling in tipc_link_xmit()

      When the function tipc_link_xmit() is given a buffer list for
      transmission, it currently consumes the list both when transmission
      is successful and when it fails, except for the special case when
      it encounters link congestion.

      This behavior is inconsistent, and needs to be corrected if we want
      to avoid problems in later commits in this series.

      In this commit, we change this to let the function consume the list
      only when transmission is successful, and leave the list with the
      sender in all other cases. We also modifiy the socket code so that
      it adapts to this change, i.e., purges the list when a non-congestion
      error code is returned.

      tipc: use bearer index when looking up active links

      struct tipc_node currently holds two arrays of link pointers; one,
      indexed by bearer identity, which contains all links irrespective of
      current state, and one two-slot array for the currently active link
      or links. The latter array contains direct pointers into the elements
      of the former. This has the effect that we cannot know the bearer id of
      a link when accessing it via the "active_links[]" array without actually
      dereferencing the pointer, something we want to avoid in some cases.

      In this commit, we do instead store the bearer identity in the
      "active_links" array, and use this as an index to find the right element
      in the overall link entry array. This change should be seen as a
      preparation for the later commits in this series.

      tipc: move link input queue to tipc_node

      At present, the link input queue and the name distributor receive
      queues are fields aggregated in struct tipc_link. This is a hazard,
      because a link might be deleted while a receiving socket still keeps
      reference to one of the queues.

      This commit fixes this bug. However, rather than adding yet another
      reference counter to the critical data path, we move the two queues
      to safe ground inside struct tipc_node, which is already protected, and
      let the link code only handle references to the queues. This is also
      in line with planned later changes in this area.

      struct 'tipc_node' currently contains two arrays for link attributes,
      one for the link pointers, and one for the usable link MTUs.

      We now group those into a new struct 'tipc_link_entry', and intoduce
      one single array consisting of such enties. Apart from being a cosmetic
      improvement, this is a starting point for the strict master-slave

      This patch uses type unsigned long, instead of long, to format the ip

      tracing: Introduce two additional marks for delay

      A fine granulity support for delay would be very useful when profiling
      VM logics, such as page allocation including page reclaim and memory
      compaction with function graph.

      Thus, this patch adds two additional marks with two changes.

       - An equal sign in mark selection function is removed to align code
         behavior with comments and documentation.

       - The function graph example related to delay in ftrace.txt is updated
         to cover all supported marks.

      ftrace: Fix function_graph duration spacing with 7-digits

      Jungseok Lee noticed the following:

      Currently, row's width of 7-digit duration numbers not aligned with
      other cases like the following example.

       3) $ 3999884 us |      }
       3)               |      finish_task_switch() {
       3)   0.365 us    |        _raw_spin_unlock_irq();
       3)   3.333 us    |      }
       3) $ 3999976 us |    }
       3) $ 3999979 us |  } /* schedule */

      As adding a single white space in case of 7-digit numbers, the format
      could be unified easily as follows.

       3) $ 2237472 us  |      }
       3)               |      finish_task_switch() {
       3)   0.364 us    |        _raw_spin_unlock_irq();
       3)   3.125 us    |      }
       3) $ 2237556 us  |    }
       3) $ 2237559 us  |  } /* schedule */

      Instead of making a special case for 7-digit numbers, the logic
      of the len and the space loop is slightly modified to make the
      two cases have the same format.

      tracing: Clean up stack tracing and fix fentry updates

      Akashi Takahiro was porting the stack tracer to arm64 and found some
      issues with it. One was that it repeats the top function, due to the
      stack frame added by the mcount caller and added by itself. This
      was added when fentry came in, and before fentry created its own stack
      frame. But x86's fentry now creates its own stack frame, and there's
      no need to insert the function again.

      This also cleans up the code a bit, where it doesn't need to do something
      special for fentry, and doesn't include insertion of a duplicate
      entry for the called function being traced.

      Now that events only add time extends after it is committed, in case
      an event comes in before it can discard the allocated event, the time
      extend needs to be stored within the event. If the event is bigger
      than then size needed for the time extend, padding must be added.
      The minimum padding size is 8 bytes. Thus if the event is 12 bytes
      (size of time extend + 4), there will not be enough room to add both
      the time extend and padding. Make sure all events are either 8 bytes
      or 16 or more bytes.

      ring-buffer: Get timestamp after event is allocated

      Move the capturing of the timestamp to after an event is allocated.
      If the event is not a commit (where it is an event that preempted
      another event), then no timestamp is needed, because the delta of
      nested events is always zero.

      If the event starts on a new page, no delta needs to be calculated
      as the full timestamp will be added to the page header, and the
      event will have a delta of zero.

      Now if the event requires a time extend (the delta does not fit
      in the 27 bit delta slot in the header), then the event is discarded,
      the length is extended to hold the TIME_EXTEND event that allows for
      a 59 bit delta, and the commit is tried again.

      If the event can't be discarded (another event came in after it),
      then the TIME_EXTEND is added directly to the allocated event and
      the rest of the event is given padding.

      tracing: Fix for non-continuous cpu ids

      Currently exception occures due to access beyond buffer_iter
      range while using index of cpu bigger than num_possible_cpus().

      powerpc/eeh: Dump PHB diag-data for non-existing PE

      When detecting EEH error on non-existing PE, including the reserved
      one, the PE is simply unfrozen without dumping the PHB diag-data,
      which is useful for locating the root cause of the EEH error. The
      patch dumps the PHB diag-data when non-existing PE reports error.

      Merge branch 'offload_fwd_mark'

      Scott Feldman says:

      ====================
      switchdev: avoid duplicate packet forwarding

      v3:

       - Per Nicolas Dichtel review: remove errant empty union.

      v2:

       - Per davem review: in sk_buff, union fwd_mark with secmark to save space
         since features appear to be mutually exclusive.
       - Per Simon Horman review:
         - fix grammar in switchdev.txt wrt fwd_mark
         - remove some unrelated changes that snuck in

      v1:

      This patchset was previously submitted as RFC.  No changes from the last
      version (v2) sent under RFC.  Including RFC version history here for 
reference.

      RFC v2:

       - s/fwd_mark/offload_fwd_mark
       - use consume_skb rather than kfree_skb when dropping pkt on egress.
       - Use Jiri's suggestion to use ifindex of one of the ports in a group
         as the mark for all the ports in the group.  This can be done with
         no additional storage (no hashtable from v1).  To pull it off, we
         need some simple recursive routines to walk the netdev tree ensuring
         all leaves in the tree (ports) in the same group (e.g. bridge)
         belonging to the same switch device will have the same offload fwd 
mark.
         Maybe someone sees a better design for the recusive routines?  They're
         not too bad, and should cover the stacked driver cases.

      RFC v1:

      With switchdev support for offloading L2/L3 forwarding data path to a
      switch device, we have a general problem where both the device and the
      kernel may forward the packet, resulting in duplicate packets on the wire.
      Anytime a packet is forwarded by the device and a copy is sent to the CPU,
      there is potential for duplicate forwarding, as the kernel may also do a
      forwarding lookup and send the packet on the wire.

      The specific problem this patch series is interested in solving is 
avoiding
      duplicate packets on bridged ports.  There was a previous RFC from Roopa
      (http://marc.info/?l=linux-netdev&m=142687073314252&w=2) to address this
      problem, but didn't solve the problem of mixed ports in the bridge from
      different devices; there was no way to exclude some ports from forwarding
      and include others.  This RFC solves that problem by tagging the 
ingressing
      packet with a unique mark, and then comparing the packet mark with the
      egress port mark, and skip forwarding when there is a match.  For the 
mixed
      ports bridge case, only those ports with matching marks are skipped.

      The switchdev port driver must do two things:

      1) Generate a fwd_mark for each switch port, using some unique key of the
         switch device (and optionally port).  This is done when the port netdev
         is registered or if the port's group membership changes (joins/leaves
         a bridge, for example).

      2) On packet ingress from port, mark the skb with the ingress port's
         fwd_mark.  If the device supports it, it's useful to only mark skbs
         which were already forwarded by the device.  If the device does not
         support such indication, all skbs can be marked, even if they're
         local dst.

      Two new 32-bit fields are added to struct sk_buff and struct netdevice to
      hold the fwd_mark.  I've wrapped these with CONFIG_NET_SWITCHDEV for now. 
I
      tried using skb->mark for this purpose, but ebtables can overwrite the
      skb->mark before the bridge gets it, so that will not work.

      In general, this fwd_mark can be used for any case where a packet is
      forwarded by the device and a copy is sent to the CPU, to avoid the kernel
      re-forwarding the packet.  sFlow is another use-case that comes to mind,
      but I haven't explored the details.

      rocker: add offload_fwd_mark support

      If device flags ingress packet as "fwd offload", mark the
      skb->offlaod_fwd_mark using the ingress port's dev->offlaod_fwd_mark.  
This
      will be the hint to the kernel that this packet has already been forwarded
      by device to egress ports matching skb->offlaod_fwd_mark.

      For rocker, derive port dev->offlaod_fwd_mark based on device switch ID 
and
      port ifindex.  If port is bridged, use the bridge ifindex rather than the
      port ifindex.

      switchdev: add offload_fwd_mark generator helper

      skb->offload_fwd_mark and dev->offload_fwd_mark are 32-bit and should be
      unique for device and may even be unique for a sub-set of ports within
      device, so add switchdev helper function to generate unique marks based on
      port's switch ID and group_ifindex.  group_ifindex would typically be the
      container dev's ifindex, such as the bridge's ifindex.

      The generator uses a global hash table to store offload_fwd_marks hashed 
by
      {switch ID, group_ifindex} key.

      Just before queuing skb for xmit on port, check if skb has been marked by
      switchdev port driver as already fordwarded by device.  If so, drop skb.  
A
      non-zero skb->offload_fwd_mark field is set by the switchdev port
      driver/device on ingress to indicate the skb has already been forwarded by
      the device to egress ports with matching dev->skb_mark.  The switchdev 
port

      ACPI / processor: remove leftover __refdata annotations

      The processor_handler structure does not reference any __init / __exit

      to be prior to commit fe7bf106ebc2 ("acpi: delete __cpuinit usage from
      all acpi files") due to the __cpuinit annotation of acpi_processor_add().
      But with that commit in place that requirement has gone.

      The same is true for the acpi_cpu_notifier notifier block.
      acpi_cpu_soft_notify() used to be marked __cpuinit but lost its
      annotation in the above mentioned commit as well. Therefore the __refdata
      annotation isn't needed there either.

      Just drop the unneded __refdata annotations to be able to catch future

      perf bench futex: Add lock_pi stresser

      Allows a way of measuring low level kernel implementation of 
FUTEX_LOCK_PI and
      FUTEX_UNLOCK_PI.

      The program comes in two flavors:

      (i) single futex (default), all threads contend on the same uaddr.  For 
the
      sake of the benchmark, we call into kernel space even when the lock is
      uncontended.  The kernel will set it to TID, any waters that come in and
      contend for the pi futex will be handled respectively by the kernel.

      (ii) -M option for multiple futexes, each thread deals with its own 
futex. This
      is a trivial scenario and only measures kernel handling of 0->TID 
transition.

      perf record: Allow filtering perf's pid via --exclude-perf

      This patch allows 'perf record' to exclude events issued by perf itself
      by '--exclude-perf' option.

      Before this patch, when doing something like:

       # perf record -a -e syscalls:sys_enter_write <cmd>

      One could easily get result like this:

       # /tmp/perf report --stdio
       ...
        # Overhead  Command  Shared Object       Symbol
        # ........  .......  ..................  ....................
        #
            99.99%  perf     libpthread-2.18.so  [.] __write_nocancel
            0.01%   ls       libc-2.18.so        [.] write
            0.01%   sshd     libc-2.18.so        [.] write
       ...

      Where most events are generated by perf itself.

      A shell trick can be done to filter perf itself out:

       # cat << EOF > ./tmp
       > #!/bin/sh
       > exec perf record -e ... --filter="common_pid != \$\$" -a sleep 10
       > EOF
       # chmod a+x ./tmp
       # ./tmp

      However, doing so is user unfriendly.

      This patch extracts evsel iteration framework introduced by patch 'perf
      record: Apply filter to all events in a glob matching' into
      foreach_evsel_in_last_glob(), and makes exclude_perf() function append
      new filter expression to each evsel selected by a '-e' selector.

      To avoid losing filters if user pass '--filter' after '--exclude-perf',
      this patch uses perf_evsel__append_filter() in both case, instead of
      perf_evsel__set_filter() which removes old filter. As a side effect, now
      it is possible to use multiple '--filter' option for one selector. They
      are combinded with '&&'.

      net/ipv6: update flowi6_oif in ip6_dst_lookup_flow if not set

      Newly created flows don't have flowi6_oif set (at least if the
      associated socket is not interface-bound). This leads to a mismatch in
      __xfrm6_selector_match() for policies which specify an interface in the
      selector (sel->ifindex != 0).

      Backtracing shows this happens in code-paths originating from e.g.
      ip6_datagram_connect(), rawv6_sendmsg() or tcp_v6_connect(). (UDP was
      not tested for.)

      In summary, this patch fixes policy matching on outgoing interface for
      locally generated packets.

      ebpf: add helper to retrieve net_cls's classid cookie

      It would be very useful to retrieve the net_cls's classid from an eBPF
      program to allow for a more fine-grained classification, it could be
      directly used or in conjunction with additional policies. I.e. docker,
      but also tooling such as cgexec, can easily run applications via net_cls
      cgroups:

        cgcreate -g net_cls:/foo
        echo 42 > foo/net_cls.classid
        cgexec -g net_cls:foo <prog>

      Thus, their respecitve classid cookie of foo can then be looked up on
      the egress path to apply further policies. The helper is desigend such
      that a non-zero value returns the cgroup id.

      enic: allow adaptive coalesce setting for msi/legacy intr

      * Allow setting of adaptive coalescing setting for all types of interrupt.

      * In msi & legacy intr, we use single interrupt for rx & tx. In this case
        tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
        Do not display tx_coal values for msi/intx. And do not allow user to set
        this as well.

      * Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
        For other values, driver does not return error. So ethtool succeeds for
        unsupported values. Introduce enic_coalesce_valid() function to validate
        the coalescing values.

      * If user requests for coalesce value greater than what adaptor supports,
        driver uses the max value. We should at least log this.

      svcrdma: Fix send_reply() scatter/gather set-up

      The Linux NFS server returns garbage in the data payload of inline
      NFS/RDMA READ replies. These are READs of under 1000 bytes or so
      where the client has not provided either a reply chunk or a write
      list.

      The NFS server delivers the data payload for an NFS READ reply to
      the transport in an xdr_buf page list. If the NFS client did not
      provide a reply chunk or a write list, send_reply() is supposed to
      set up a separate sge for the page containing the READ data, and
      another sge for XDR padding if needed, then post all of the sges via
      a single SEND Work Request.

      The problem is send_reply() does not advance through the xdr_buf
      when setting up scatter/gather entries for SEND WR. It always calls
      dma_map_xdr with xdr_off set to zero. When there's more than one
      sge, dma_map_xdr() sets up the SEND sge's so they all point to the
      xdr_buf's head.

      The current Linux NFS/RDMA client always provides a reply chunk or
      a write list when performing an NFS READ over RDMA. Therefore, it
      does not exercise this particular case. The Linux server has never
      had to use more than one extra sge for building RPC/RDMA replies
      with a Linux client.

      However, an NFS/RDMA client _is_ allowed to send small NFS READs
      without setting up a write list or reply chunk. The NFS READ reply
      fits entirely within the inline reply buffer in this case. This is
      perhaps a more efficient way of performing NFS READs that the Linux
      NFS/RDMA client may some day adopt.

      NFS/RDMA Release resources in svcrdma when device is removed

      When removing underlying RDMA device, the rmmod will hang forever if there
      are any outstanding NFS/RDMA client mounts. The outstanding NFS/RDMA 
counts
      could also prevent the server from shutting down. Further debugging shows
      that the existing connections are not teared down and resource are not
      released when receiving RDMA_CM_EVENT_DEVICE_REMOVAL event. It seems the
      original code missing svc_xprt_put() in RDMA_CM_EVENT_REMOVAL event 
handler
      thus svc_xprt_free is never invoked to release the existing connection
      resources.

      The patch has been passed removing, adding device back and forth without
      stopping NFS/RDMA service. This will also allow a device to be unplugged
      and swapped out without shutting down NFS service.

      nfsd: Set lc_size_chg before ops->proc_layoutcommit

      After proc_layoutcommit success, i_size_read(inode) always >= new_size.
      Just set lc_size_chg before proc_layoutcommit, if proc_layoutcommit
      failed, nfsd will skip the lc_size_chg, so it's no harm.

      perf record: Apply filter to all events in a glob matching

      There is an old problem in perf's filter applying which first posted at
      Sep. 2014 at https://lkml.org/lkml/2014/9/9/944 that, if passing
      multiple events in a glob matching expression in cmdline then add
      '--filter' after them, the filter will be applied on only the last one.

      For example:

       # dd if=/dev/zero of=/dev/null &
       [1] 464
       # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' 
sleep 0.1
       [ perf record: Woken up 1 times to write data ]
       [ perf record: Captured and wrote 0.239 MB perf.data (2094 samples) ]
       # perf report --stdio | tee
       ...
       # Samples: 2K of event 'syscalls:sys_enter_read'
       # Event count (approx.): 2092
       ...
       # Samples: 2  of event 'syscalls:sys_exit_read'
       # Event count (approx.): 2
       ...

      In this example, filter only applied on 'syscalls:sys_exit_read', and
      there's no way to set filter for ''syscalls:sys_enter_read'.

      This patch adds a 'cmdline_group_boundary' for 'struct evsel', and
      apply filter on all events between two boundary marks.

      After applying this patch:

       # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' 
sleep 0.1
       [ perf record: Woken up 1 times to write data ]
       [ perf record: Captured and wrote 0.031 MB perf.data (3 samples) ]
       # perf report --stdio | tee
       ...
       # Samples: 1  of event 'syscalls:sys_enter_read'
       # Event count (approx.): 1
       ...
       # Samples: 2  of event 'syscalls:sys_exit_read'
       # Event count (approx.): 2
       ...

      perf trace: Support 'strace' syscall event groups

      I.e.:

        $ cat ~/share/perf-core/strace/groups/file
        access
        chmod
        creat
        execve
        faccessat
        getcwd
        lstat
        mkdir
        open
        openat
        quotactl
        readlink
        rename
        rmdir
        stat
        statfs
        symlink
        unlink
        $

      Then, on a quiet desktop, try running this and then moving your mouse to
      see the deluge of mouse related activity:

        # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
        Added new event:
          probe:vfs_getname    (on getname_flags:72 with 
pathname=filename:string)

        You can now use it in all perf tools, such as:

        perf record -e probe:vfs_getname -aR sleep 1
        #
        # trace --ev probe:vfs_getname --filter-pids 2232 -e file

      Need to combine that raw_syscalls:sys_enter(open) + probe:vfs_getname +
      raw_syscalls:sys_exit(open) sequence...

      Now, if you're bored, please write some more syscall groups, like the ones
      in 'strace' and send it our way :-)

      clk: sirf: Properly include clk.h

      Clock provider drivers generally shouldn't include clk.h because
      it's the consumer API. Move the include of clk.h into
      clk-common.c because that's the only file that's really using
      clk.h, even if it's included into the atlas6 and prima2 files.

      Clock provider drivers generally shouldn't include clk.h because

      slab for them.

      Now that we have more details about the TIMING_CFG register layout

      regmap: debugfs: Allow writes to cache state settings

      Allow the user to write the cache_only and cache_bypass settings.
      This can be useful for debugging.

      Since this can lead to the hardware getting out-of-sync with the
      cache, at least for the period that the cache state is forced, the
      kernel is tainted and the action is recorded in the kernel log.

      When disabling cache_only through debugfs a cache sync will be performed.

      perf strlist: Allow substitutions from file contents in a given directory

      So, if we have an strlist equal to:

         "file,close"

      And we call it as:

         struct strlist_config *config = { .dirname = "~/strace/groups", };
         struct strlist *slist = strlist__new("file, close", &config);

      And we have:
        $ cat ~/strace/groups/file
        access
        open
        openat
        statfs

      Then the resulting strlist will have these contents:

        [ "access", "open", "openat", "statfs", "close" ]

      This will be used to implement strace syscall groups in 'perf trace',
      but can be used in some other tool, thus being implemented in 'strlist'.

      iio: dht11: Use new function ktime_get_resolution_ns()

      This cleans up the most ugly workaround in this driver. There are no
      functional changes yet in the decoding algorithm, but we improve the
      following things:
       * Get rid of spurious warning messages on systems with fast HRTIMER.
       * If the clock is not fast enough for decoding to work, we give
         up immediately.
       * In that case we return EAGAIN instead of EIO, so it's easier to
         discriminate causes of failure.

      Returning EAGAIN is somewhat controversial: It's technically correct
      as a faster clock might become available. OTOH once all clocks are
      enabled this is a permanent error. There is no ECLOCKTOOSLOW error
      code.

      iio: adc: vf610: Determine sampling frequencies by using minimum sample 
time

      The driver currently does not take into account the minimum sample time
      as per the Figure 6-8 Chapter 9.1.1 12-bit ADC electrical characteristics.
      We set a static amount of cycles instead of considering the sample time
      as a given value, which depends on hardware characteristics.

      Determine sampling frequencies by first reading the device tree property
      node and then calculating the required Long Sample Time Adder (LSTAdder)
      value, based on the ADC clock frequency and sample time value obtained
      from the device tree. This LSTAdder value is then used for calculating
      the sampling frequencies possible.

      In case the sample time property is not specified through the device
      tree, a safe default value of 1000ns is assumed.

      regulator: rk808: fixed the overshoot when adjust voltage

      There is a overshoot in DCDC1/DCDC2, we have 2 method to workaround:
      1st is use dvs pin to switch the voltage between value in BUCKn_ON_VSEL
      and BUCKn_DVS_VSEL. If DVS pin is inactive, the voltage of DCDC1/DCDC2
      are controlled by BUCKn_ON_VSEL, when we pull dvs1/dvs2 pin to active,
      they would be controlled by BUCKn_DVS_VSEL. In this case, the ramp rate
      is same as the value programmed in BUCKn_RATE, and the fastest rate is
      10mv/us.
      2nd method is gradual adjustment, adjust the voltage to a target value
      step by step via i2c, each step is set to 100 mA. If you write the
      voltage directly using an i2c write the rk808 will always ramp as fast
      as it possibly can, about 100mv/us.

      function seem to do nothing that can interfere with devm_regulator_put,
      making it safe to allow devm_regulator_put to occur after the end of the
      remove function.

      Convert the calls to clk_get to devm_clk_get, and remove the corresponding
      calls to clk_put in the probe and remove functions.

      Replace various gotos by direct returns, and drop unneeded labels.

      We check the ATS state (enabled/disabled) and fetch the PCI ATS Invalidate
      Queue Depth in performance-sensitive paths.  It's easy to cache these,
      which removes dependencies on PCI.

      Remember the ATS enabled state.  When enabling, read the queue depth once
      and cache it in the device_domain_info struct.  This is similar to what

      power: reset: at91: add sama5d3 reset function

      This patch introduces a new compatible string: "atmel,sama5d3-rstc" and
      new reset function for sama5d3 and later chips.

      As in sama5d3 or later chips, we don't have to shutdown the DDR
      controller before reset. Shutdown the DDR controller before reset is a
      workaround to avoid DDR signal driving the bus, but since sama5d3 and
      later chips there is no such a conflict.

      So in this patch:
         1. the sama5d3 reset function only need to write the rstc register
      and return.
         2. we can remove the code related with sama5d3 DDR controller as
      we don't use it at all.

      futex: Fault/error injection capabilities

      Although futexes are well known for being a royal pita,
      we really have very little debugging capabilities - except
      for relying on tglx's eye half the time.

      By simply making use of the existing fault-injection machinery,
      we can improve this situation, allowing generating artificial
      uaddress faults and deadlock scenarios. Of course, when this is
      disabled in production systems, the overhead for failure checks
      is practically zero -- so this is very cheap at the same time.
      Future work would be nice to now enhance trinity to make use of
      this.

      There is a special tunable 'ignore-private', which can filter
      out private futexes. Given the tsk->make_it_fail filter and
      this option, pi futexes can be narrowed down pretty closely.

      For platforms that have HW coherency support:
      -PPC-based: the update has no effect; CAAM coherency already works
      due to the IOMMU (PAMU) driver setting the correct memory coherency
      attributes

      drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface

      This patch adds the gfx8 interface file between amdgpu and amdkfd. This
      interface file is currently in use when running on a Carrizo-based
      system.

      The interface itself is represented by a pointer to struct
      kfd_dev. The pointer is located inside amdgpu_device structure.

      All the register accesses that amdkfd need are done using this
      interface. This allows us to avoid direct register accesses in
      amdkfd proper, while also allows us to avoid locking between
      amdkfd and amdgpu.

      The single exception is the doorbells that are used in both of
      the drivers. However, because they are located in separate pci
      bar pages, the danger of sharing registers between the drivers
      is minimal.

      Having said that, we are planning to move the doorbells as well
      to amdgpu.

      The gfx7 interface is used when it is run on a Kaveri-based system.

      This interface file was used for bring-up of amdkfd on amdgpu and for
      debugging purposes. For users who would like to run HSA on Kaveri, please
      use the radeon graphic driver.

      Note: CONFIG_DRM_AMDGPU_CIK must be selected for amdgpu to handle Kaveri.

      drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd interface

      This patch adds an interface file between amdgpu and amdkfd. This
      interface file is H/W agnostic, thus containing functions that
      operate the same for any AMD APU/GPU H/W generation.

      The functions in this interface mirror (some) of the functions in
      radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
      are:

      - amdgpu_amdkfd_init - initialize the amdkfd module
      - amdgpu_amdkfd_load_interface - load the H/W interface according to the
        currently probed device
      - amdgpu_amdkfd_device_probe - probe the device in amdkfd
      - amdgpu_amdkfd_device_init - initialize the device in amdkfd
      - amdgpu_amdkfd_interrupt - call the ISR of amdkfd
      - amdgpu_amdkfd_suspend - suspend callback from amdgpu
      - amdgpu_amdkfd_resume - resume callback from amdgpu

      This patch also modifies the relevant amdgpu files, to use this new
      interface.

      ARM: pxa: transition to dmaengine phase 1

      In order to slowly transition pxa to dmaengine, the legacy code will now
      rely on dmaengine to request a channel.

      This implies that PXA architecture selects DMADEVICES and PXA_DMA,
      which is not pretty. Yet it enables PXA drivers to be ported one by one,
      with part of them using dmaengine, and the other part using the legacy
      code.

      ixgbe: Don't report flow director filter's status

      For two reasons I want to disable this:
      1. Not any part actually check the report status(Alexander Duyck)
      2. To report hash value of a packet to stack,
         RSS -> 32bits hash value
         Perfect match fdir filter -> 13bits hash value
         Hashed-based fdir filter -> 31bits hash value

         fdir filter might hash on masked tuples for IP address,
         so it's still not desirable for usage.

      So for now, just stick to RSS 32bits hash value.

      igb: Pull timestamp from fragment before adding it to skb

      This change makes it so that we pull the timestamp from the fragment 
before
      we add it to the skb.  By doing this we can avoid a possible issue in 
which
      the fragment can possibly be less than IGB_RX_HDR_LEN due to the timestamp
      being pulled after the copybreak check.

      While making this change I realized we could also pull the rest of the
      igb_pull_tail function into igb_add_rx_frag since in the case of igb,
      unlike ixgbe, we are able to unmap the entire buffer before calling
      add_rx_frag so merging the two allows for sharing of code between the two
      merged functions.

      clarify implementation of ethtool's get_ts_info op

      This patch adds some clarification about the intended way to implement
      both SIOCSHWTSTAMP and ethtool's get_ts_info. The HWTSTAMP API has
      several Rx filters which are very specific, as well as more general
      filters. The specific filters really only exist to support some broken
      hardware which can't fully implement the generic filters. This patch
      adds clarification that it is okay to support the specific filters in
      SIOCSHWTSTAMP by upscaling them to the generic filters. In addition,
      update the header for ethtool_ts_info to specify that drivers ought to
      only report the filters they support without upscaling in this manner.

      The grace-period kthread sleeps waiting to do a force-quiescent-state
      scan, and when awakened sets rsp->gp_state to RCU_GP_DONE_FQS.
      However, this is confusing because the kthread has not done the
      force-quiescent-state, but is instead just starting to do it.  This commit
      therefore renames RCU_GP_DONE_FQS to RCU_GP_DOING_FQS in order to make

      rcu: Add stall warnings to synchronize_sched_expedited()

      Although synchronize_sched_expedited() historically has no RCU CPU stall
      warnings, the availability of the rcupdate.rcu_expedited boot parameter
      invalidates the old assumption that synchronize_sched()'s stall warnings
      would suffice.  This commit therefore adds RCU CPU stall warnings to
      synchronize_sched_expedited().

      rcu: Extend expedited funnel locking to rcu_data structure

      The strictly rcu_node based funnel-locking scheme works well in many
      cases, but systems with CONFIG_RCU_FANOUT_LEAF=64 won't necessarily get
      all that much concurrency.  This commit therefore extends the funnel
      locking into the per-CPU rcu_data structure, providing concurrency equal
      to the number of CPUs.

      rcu: Consolidate last open-coded expedited memory barrier

      One of the requirements on RCU grace periods is that if there is a
      causal chain of operations that starts after one grace period and
      ends before another grace period, then the two grace periods must
      be serialized.  There has been (and might still be) code that relies
      on this, for example, certain types of reference-counting code that
      does a call_rcu() within an RCU callback function.

      This requirement is why there is an smp_mb() at the end of both
      synchronize_sched_expedited() and synchronize_rcu_expedited().
      However, this is the only smp_mb() in these functions, so it would
      be nicer to consolidate it into rcu_exp_gp_seq_end().  This commit
      does just that.

      rcu: Make synchronize_rcu_expedited() use sequence-counter scheme

      Although synchronize_rcu_expedited() uses a sequence-counter scheme, it
      is based on a single increment per grace period, which means that tasks
      piggybacking off of concurrent grace periods may be forced to wait longer
      than necessary.  This commit therefore applies the new sequence-count
      functions developed for synchronize_sched_expedited() to speed things
      up a bit and to consolidate the sequence-counter implementation.

      rcu: Abstract sequence counting from synchronize_sched_expedited()

      This commit creates rcu_exp_gp_seq_start() and rcu_exp_gp_seq_end() to
      bracket an expedited grace period, rcu_exp_gp_seq_snap() to snapshot the
      sequence counter, and rcu_exp_gp_seq_done() to check to see if a full
      expedited grace period has elapsed since the snapshot.  These will be
      applied to synchronize_rcu_expedited().  These are defined in terms of
      underlying rcu_seq_start(), rcu_seq_end(), rcu_seq_snap(), rcu_seq_done(),
      which will be applied to _rcu_barrier().

      One reason that this commit doesn't use the seqcount primitives themselves
      is that the smp_wmb() in those primitive is insufficient due to the fact
      that expedited grace periods do reads as well as writes.  In addition,
      the read-side seqcount primitives detect a potentially partial change,
      where the expedited primitives instead need a guaranteed full change.

      rcu: Make expedited GP CPU stoppage asynchronous

      Sequentially stopping the CPUs slows down expedited grace periods by
      at least a factor of two, based on rcutorture's grace-period-per-second
      rate.  This is a conservative measure because rcutorture uses unusually
      long RCU read-side critical sections and because rcutorture periodically
      quiesces the system in order to test RCU's ability to ramp down to and
      up from the idle state.  This commit therefore replaces the stop_one_cpu()
      with stop_one_cpu_nowait(), using an atomic-counter scheme to determine
      when all CPUs have passed through the stopped state.

      rcu: Rework synchronize_sched_expedited() counter handling

      Now that synchronize_sched_expedited() have a mutex, it can use simpler
      work-already-done detection scheme.  This commit simplifies this scheme
      by using something similar to the sequence-locking counter scheme.
      A counter is incremented before and after each grace period, so that
      the counter is odd in the midst of the grace period and even otherwise.
      So if the counter has advanced to the second even number that is
      greater than or equal to the snapshot, the required grace period has
      already happened.

      rcu: Switch synchronize_sched_expedited() to stop_one_cpu()

      The synchronize_sched_expedited() currently invokes try_stop_cpus(),
      which schedules the stopper kthreads on each online non-idle CPU,
      and waits until all those kthreads are running before letting any
      of them stop.  This is disastrous for real-time workloads, which
      get hit with a preemption that is as long as the longest scheduling
      latency on any CPU, including any non-realtime housekeeping CPUs.
      This commit therefore switches to using stop_one_cpu() on each CPU
      in turn.  This avoids inflicting the worst-case scheduling latency
      on the worst-case CPU onto all other CPUs, and also simplifies the
      code a little bit.

      Follow-up commits will simplify the counter-snapshotting algorithm
      and convert a number of the counters that are now protected by the
      new ->expedited_mutex to non-atomic.

      Currently if the rcu_fanout_leaf boot parameter is out of bounds (that
      is, less than RCU_FANOUT_LEAF or greater than the number of bits in an
      unsigned long), a warning is issued and execution continues with the
      out-of-bounds value.  This can result in all manner of failures, so this
      patch resets rcu_fanout_leaf to RCU_FANOUT_LEAF when an out-of-bounds
      condition is detected.

      rcu: Shut up bogus gcc array bounds warning

      Because gcc does not realize a loop would not be entered ever
      (i.e. in case of rcu_num_lvls == 1):

        for (i = 1; i < rcu_num_lvls; i++)
          rsp->level[i] = rsp->level[i - 1] + levelcnt[i - 1];

      some compiler (pre- 5.x?) versions give a bogus warning:

        kernel/rcu/tree.c: In function â??rcu_init_one.isra.55â??:
        kernel/rcu/tree.c:4108:13: warning: array subscript is above array 
bounds [-Warray-bounds]
           rsp->level[i] = rsp->level[i - 1] + rsp->levelcnt[i - 1];
                     ^
      Fix that warning by adding an extra item to rcu_state::level[]
      array. Once the bogus warning is fixed in gcc and kernel drops
      support of older versions, the dummy item may be removed from
      the array.

      pinctrl/sirf: Prepare xxx_gpio-handle_irq for irq argument removal

      The irq argument of most interrupt flow handlers is unused or merily
      used instead of a local variable. The handlers which need the irq
      argument can retrieve the irq number from the irq descriptor.

      Search and update was done with coccinelle and the invaluable help of

      pinctrl: add support for Qualcomm Technologies QDF2xxx ARM64 SoCs

      Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs,
      which uses the Qualcomm Technologies TLMM pinctrl/gpio device.  This
      driver is probed via ACPI and uses the pinctrl-msm.c backend driver.

      This driver is intended to be used only an ACPI-enabled system.  As such,
      UEFI will handle all pin control configuration, so this driver does not
      provide pin control functions.  It is effectively a GPIO-only driver.

      The register layout of the PSC devices differ between MPC5121 and
      MPC5125, but the registers are named nearly identical and their purpose
      is similar enough ("freescale identical") such that substituting
      mpc52xx_psc by mpc5125_psc is nearly enough to make the driver work on
      MPC5125. To keep supporting MPC5121 this patch introduces a cpp
      macro to select the right struct that defines the register layout.

      ASoC: rsnd: add MIX (Mixer) support

      This patch adds MIX (Mixer) initial support for rsnd driver.
      It is assuming that this MIX is used via DPCM.

      This is sample code for playback.

        CPU1  : [MEM] -> [SRC2] -> [CTU03] -+

        sound {
                compatible = "renesas,rsrc-card";

                ...

                cpu@0 {
                        sound-dai = <&rcar_sound 0>;
                };

                };

                codec {

      ASoC: rsnd: add CTU (Channel Transfer Unit) prototype support

      This patch adds CTU (Channel Transfer Unit) support for rsnd driver.
      But, it does nothing to data at this point, but is required for MIX
      support.

      CTU design is a little different from other IPs (CTU0 is including
      CTU00 - CTU03, and CTU1 is including CTU10 - CTU13, these have different
      register mapping) We need to care about it on this driver.

      ASoC: rsnd: update Audio DMA path search method

      Current rsnd driver is assuming Audio DMAC / Audio DMAC peri peri
      are used from SSI/SSIU/SRC/DVC. But we will add CTU/MIX to this driver.
      Then, current DMA path searching method is not understandable, and good
      enough for this purpose. This patch update DMA path search method, more
      simply.

      memory: add ARM PL172 MultiPort Memory Controller driver

      This driver makes it possible to configure the static memory
      chip selects on the ARM PL172 MultiPort Memory Controller
      from a set of properties in DT. Configuration of dynamic
      memory is not supported and is left to the boot loader.

      The intended usage is to setup timing and configuration for
      static memory devices like NAND and NOR Flash before they
      are probed by a driver.

      arm64: dts: add Rockchip rk3368 core dtsi and board dts for the r88 board

      In terms of peripherals the rk3368 is quite similar to the rk3288, which
      makes it possible to have a lot basic components working in the first go.
      More to follow once I tracked down all the tiny differences that still
      exist in some parts.

      With these dts files, the R88 board is able to boot from an attached
      usb device and most likely from its emmc too, if the emmc uses a standard
      partition table instead of Rockchip's own one - the emmc itself is
      detected correctly.

      This series migrates ARM clockevent drivers (present in arch/arm/

      drivers to use new states (like: ONESHOT_STOPPED, etc.) of a clockevent

      ext4 crypto: check for too-short encrypted file names

      An encrypted file name should never be shorter than an 16 bytes, the
      AES block size.  The 3.10 crypto layer will oops and crash the kernel
      if ciphertext shorter than the block size is passed to it.

      Fortunately, in modern kernels the crypto layer will not crash the
      kernel in this scenario, but nevertheless, it represents a corrupted
      directory, and we should detect it and mark the file system as
      corrupted so that e2fsck can fix this.

      Add videobuf2 specific vb2_qbuf and vb2_dqbuf trace events that mirror the
      v4l2_qbuf and v4l2_dqbuf trace events, only they include additional
      information about queue fill state and are emitted right before the buffer

      block: make /sys/block/<dev>/queue/discard_max_bytes writeable

      Lots of devices support huge discard sizes these days. Depending
      on how the device handles them internally, huge discards can
      introduce massive latencies (hundreds of msec) on the device side.

      We have a sysfs file, discard_max_bytes, that advertises the max
      hardware supported discard size. Make this writeable, and split
      the settings into a soft and hard limit. This can be set from
      'discard_granularity' and up to the hardware limit.

      Add a new sysfs file, 'discard_max_hw_bytes', that shows the hw
      set limit.

      [media] coda: add macroblock tiling support

      Storing internal frames in macroblock tiled order improves memory
      access patterns by allowing increased burst sizes when transferring
      the uncompressed macroblocks to or from main memory.
      The translation logic only supports a single chroma base address,
      so this is only supported for the chroma interleaved NV12 format.

      Since the rotator used to copy the decoder output into the v4l2
      capture buffers does not seem to support the tiled format correctly,
      only enable it in the encoder for now.

      [media] coda: fix bitstream preloading for MPEG4 decoding

      All decoder instances using the BIT processor should preload buffers
      into the bitstream ring buffer, including MPEG4 decoding. Fix this
      by explicitly stating the above condition instead of listing all
      relevant input formats.

      x86/entry: Fix _TIF_USER_RETURN_NOTIFY check in prepare_exit_to_usermode

      Linus noticed that the early return check was missing
      _TIF_USER_RETURN_NOTIFY.  If the only work flag was
      _TIF_USER_RETURN_NOTIFY, we'd skip user return notifiers.  Fix
      it. (This is the only missing bit.)

      This fixes double faults on a KVM host.  It's the same issue as
      last time, except that this time it's very easy to trigger.
      Apparently no one uses -next as a KVM host.

      ( I'm still not quite sure what it is that KVM does that blows up
        so badly if we miss a user return notifier.  My best guess is that KVM
        lets KERNEL_GS_BASE (i.e. the user's gs base) be negative and fixes
        it up in a user return notifier.  If we actually end up in user mode
        with a negative gs base, we blow up pretty badly. )

      [media] coda: clamp frame sequence counters to 16 bit

      This is already done for one side of the comparison with the expectation
      that the HW counter rolls over at the 16 bit boundary. This is true when
      decoding a h.264 stream, but doesn't hold for at least MJPEG. As we don't
      know the exact wrap-around point for this format just clamp the HW counter
      to the same 16 bits. This should be enough to detect most of the errors
      and saves us from doing different comparisons based on the decoded format.

      mac80211: select an AID when creating new mesh STAs

      Instead of using peer link id for AID, generate a new
      AID when creating mesh STAs in the kernel peering manager.
      This enables smaller TIM elements and more closely follows
      the standard, and it also enables mesh to work on drivers
      that require a valid AID when the STA is inserted (ath10k
      firmware has this requirement, for example).

      In the case of userspace-managed stations, we use the AID
      from NL80211_CMD_NEW_STATION.

      mac80211: mesh: separate plid and aid concepts

      According to 802.11-2012 13.3.1, a mesh STA should assign an AID
      upon receipt of a mesh peering open frame rather than using the link
      id of the peer.  Using the peer link id has two potential issues:
      it may not be unique among the peers, and by its nature it is random,
      so the TIM may not compress well.

      In preparation for allocating it properly, use sta->sta.aid, but keep
      the existing behavior of using the plid in the aid we send.

      mac80211: clear local->suspended before calling drv_resume()

      Currently, mac80211 calls drv_resume() on wowlan resume,
      but drops any incoming frame until local->suspended is
      cleared later on.

      This requires the low-level driver to support a new state,
      in which it is expected to fully work (as it was resumed)
      but not passing rx frames yet (as they will be dropped).

      iwlwifi (and probably other drivers as well) has issues
      supporting such mode.

      Since in the wowlan case we already short-circuit
      ieee80211_reconfig, there's nothing that prevents us from
      clearing local->suspend before calling drv_resume(),
      and letting the low-level driver work normally.

      cfg80211: allow mgmt_frame_register callback to sleep

      This callback is currently not allowed to sleep, which makes it more
      difficult to implement proper driver methods in mac80211 than it has
      to be. Instead of doing asynchronous work here in mac80211, make it
      possible for the callback to sleep by doing some asynchronous work
      in cfg80211. This also enables improvements to other drivers, like
      ath6kl, that would like to sleep in this callback.

      While at it, also fix the code to call the driver on the implicit
      unregistration when an interface is removed, and do that also when
      a P2P-Device wdev is destroyed (otherwise we leak the structs.)

      mac80211: TDLS: correctly configure SMPS state

      The IEEE802.11-2012 specification is vague regarding SMPS operation during
      TDLS. It does not define a clear way to transition between SMPS states.

      To avoid interop issues, set SMPS to off when TDLS peers are connected.
      Accomplish this by extending the definition of the AUTOMATIC state. If the
      driver forces a state other than OFF, disconnect all TDLS peers.

      While at it, avoid changing the SMPS state of the peer STA. We have no
      way to control it, so try and behave correctly towards it.

      Move the TDLS peer-teardown function to where the rest of the TDLS code
      resides.

      mac80211: enable assoc check for mesh interfaces

      We already set a station to be associated when peering completes, both
      in user space and in the kernel.  Thus we should always have an
      associated sta before sending data frames to that station.

      Failure to check assoc state can cause crashes in the lower-level driver
      due to transmitting unicast data frames before driver sta structures
      (e.g. ampdu state in ath9k) are initialized.  This occurred when
      forwarding in the presence of fixed mesh paths: frames were transmitted
      to stations with whom we hadn't yet completed peering.

      mac80211: mac80211: Check SN for deactivated mpaths

      When processing a PREQ or PREP it's critical to use the incoming SN. If
      that is improperly done routing loops and other types of badness can
      happen. But the code was always processing path messages for deactivated
      paths. This path fixes that so that if we have a valid SN then we use it
      to verify that it is a message we can accept. For reference the relevant
      section of the standard is 13.10.8.4 which doesn't address the deactivated
      path case at all.

      I also included a special case for when our peer reboots or restarts
      networking. This is an important case because without it there can be a
      very long delay before we accept path messages from that peer. It's also a
      simple case and intimately associated with processing messages for
      deactivated paths so I used one patch instead of two.

      mac80211: mesh: don't invalidate SN on discovery failure

      The 2012 spec mentions that path SNs can be invalid when created (see
      section 13.10.8.4 table 13-9) but AFAICT never talks about invalidating
      SNs. Which makes sense: if we have figured out the path to a target at a
      certain SN then we want to remember that fact. Failing to do so can lead
      to routing loops because if we don't have a valid SN then we have no way
      of knowing whether an incoming path message leads to or away from the
      target.

      However currently when discovery fails we zero out mpath->flags which
      clears MESH_PATH_SN_VALID. This patch fixes that so that only the
      discovery relevant flags are cleared.

      mac80211: upgrade BW of TDLS peers when possible

      Define a station chandef, to be used for wider-bw TDLS peers. When both
      peers support the feature, upgrade the channel bandwidth to the maximum
      allowed by both peers and regulatory. Currently widths up to 80MHz are
      supported in the 5GHz band.

      When a TDLS peer connects/disconnects recalculate the channel type of the
      current chanctx.
      Make the chanctx width calculation consider wider-bw TDLS peers and
      similarly fix the max_required_bw calculation for the chanctx min_def.
      Since the sta->bandwidth is calculated only later on, take
      bss_conf.chandef.width as the minimal width for station interface.

      Set the upgraded channel width in the VHT-operation set during TDLS setup.

      mac80211: define TDLS wider BW support bits

      Allow a device to specify support for the TDLS wider-bandwidth feature.
      Indicate this support during TDLS setup in the ext-capab IE and set an
      appropriate station flag when our TDLS peer supports it.
      This feature gives TDLS peers the ability to use a wider channel than
      the base width of the BSS. For instance VHT capable TDLS peers connected
      on a 20MHz channel can extend the channel to 80MHz, if regulatory
      considerations allow it.

      Do not cap the bandwidth of such stations by the current BSS channel width
      in mac80211.

      Currently, the station hash table lookup (or iteration) must

      Duplicate the MAC address next to the hash node to get rid of

      mac80211: support device/driver PN check for CCMP/GCMP

      When there are multiple RX queues, the PN checks in mac80211 cannot be
      used since packets might be processed out of order on different CPUs.

      Allow the driver to report that the PN has been checked, drivers that
      will use multi-queue RX will have to set this flag.

      For now, the flag is only valid when the frame has been decrypted, in
      theory that restriction doesn't have to be there, but in practice the
      hardware will have decrypted the frame already.

      mac80211: don't store napi struct

      When introducing multiple RX queues, a single NAPI struct will not
      be sufficient. Instead of trying to store multiple, simply change
      the API to have the NAPI struct passed to the RX function. This of
      course means that drivers using rx_irqsafe() cannot use NAPI, but
      that seems a reasonable trade-off, particularly since only two of
      all drivers are currently using it at all.

      While at it, we can now remove the IEEE80211_RX_REORDER_TIMER flag
      again since this code path cannot have a napi struct anyway.

      crypto: poly1305 - Add a SSE2 SIMD variant for x86_64

      Implements an x86_64 assembler driver for the Poly1305 authenticator. This
      single block variant holds the 130-bit integer in 5 32-bit words, but uses
      SSE to do two multiplications/additions in parallel.

      When calling updates with small blocks, the overhead for kernel_fpu_begin/
      kernel_fpu_end() negates the perfmance gain. We therefore use the
      poly1305-generic fallback for small updates.

      For large messages, throughput increases by ~5-10% compared to
      poly1305-generic:

      [media] stk1160: Add frame scaling support

      This commit implements frame decimation for stk1160, which allows
      to support format changes instead of a static frame size.

      The stk1160 supports independent row and column decimation, in two
      different modes:
       * set a number of rows/columns units to skip for each unit sent.
       * set a number of rows/columns units to send for each unit skipped.

      This effectively allows to achieve different frame scaling ratios.

      The unit number can be set to either two row/columns sent/skipped,
      or four row/columns sent/skipped. Since the video format (UYVY)
      has 4-bytes, using a unit number of two row/columns results
      in frame color 'shifting', so set to four row/columns sent/skipped.

      pinctrl: qcom: spmi-mpp: Transpose pinmux function

      The "function" of the MPP driver was inherited from the GPIO driver, but 
the
      differences between the two hardware blocks makes both the driver and the
      device tree binding to be awkward.

      Instead of overloading the "normal" function with various modes this patch
      transposes the pinmux function to represent the three operating modes of 
the
      MPP (digital, analog and current sink). The properties of pin pairing and 
DTEST
      routing is moved to separate properties.

      ARM: add basic support for on-demand backtrace of other CPUs

      As we now have generic infrastructure to support backtracing of other
      CPUs in the system on lockups, we can start to implement this for ARM.
      Initially, we add an IPI based implementation, as the GIC code needs
      modification to support the generation of FIQ IPIs, and not all ARM
      platforms have the ability to raise a FIQ in the non-secure world.

      This provides us with a "best efforts" implementation in the absence
      of FIQs.

      nmi: create generic NMI backtrace implementation

      x86s NMI backtrace implementation (for arch_trigger_all_cpu_backtrace())
      is fairly generic in nature - the only architecture specific bits are
      the act of raising the NMI to other CPUs, and reporting the status of
      the NMI handler.

      These are fairly simple to factor out, and produce a generic
      implementation which can be shared between ARM and x86.

      This patch looks for the cleared F01 control register and writes the
      correct value based on interrupt mask computed while scanning the PDT.

      HID: wacom: Properly free inputs if 'wacom_allocate_inputs' fails

      The 'wacom_allocate_inputs' function tries to allocate three input 
devices: one
      each for the pen, touch, and pad. The pointers that are returned by the
      'wacom_allocate_input' calls are temporarily stored to local variables 
where
      they are checked to ensure they're non-null before storing them in the
      'wacom_wac' structure. If an allocation fails,  the 'wacom_free_inputs'
      function is called to reclaim the memory. Unfortunately, 
'wacom_free_inputs' is
      called prior to the pointers being copied, so it is not actually able to 
free
      anything.

      This patch has the calls to 'wacom_allocate_input' store the pointer 
directly
      in the 'wacom_wac' structure where they can be freed. Also, it replaces 
the
      call to 'wacom_free_inputs' with the (more general) 'wacom_clean_inputs' 
and
      removes the no-longer-used function.

      acpi-cpufreq: Fix an ACPI perf unregister issue

      As policy->cpu may not be same in acpi_cpufreq_cpu_init() and
      acpi_cpufreq_cpu_exit(). There is a risk that we use different CPU
      to un/register ACPI performance. So 
acpi_processor_unregister_performance()
      may not be able to do the cleanup work. That causes a memory leak. And
      if there will be another acpi_processor_register_performance() call,
      it may also fail thanks to the internal check of pr->performace.

      So add a new struct acpi_cpufreq_data field, acpi_perf_cpu, to fix
      this issue.

      acpi-cpufreq: replace per_cpu with driver_data of policy

      Drivers can store their internal per-policy information in
      policy->driver_data, lets use it.

      we have benefits after this replacing.
      1) memory saving.
      2) policy is shared by several cpus, per_cpu seems not correct. using
      *driver_data* is more reasonable.
      3) fix a memory leak in acpi_cpufreq_cpu_exit. as policy->cpu might
      change during cpu hotplug. So sometimes we cant't free *data*, use
      *driver_data* to fix it.
      4) fix a zero return value of get_cur_freq_on_cpu. Only per_cpu of
      policy->cpu is set to *data*, if we try to get cpufreq on other cpus, we
      get zero instead of correct values. Use *driver_data* to fix it.

      ASoC: rsnd: tidyup data align position

      Sound L/R order of SSI is different from Linux sound data order.
      So current rsnd driver is using DALIGN (= data align) to exchange data
      align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted
      sound volume will be exchanged if user used volume control on DVC.
      Because SSIU which exchanges data align is located after DVC.

        MEM -> SRC -> DVC -> SSI

      This patch exchanges data align SRC if possible

      are for audio data bits, some of them (= CTU/MIX) are for audio data

      Add an optional delay_us field in reg_sequence to allow the client to
      specify a delay (in microseconds) to be applied after any given write
      in a sequence of writes.

      We treat a delay in a sequence the same way we treat a page change as
      they are logically similar in that you can coalesce all write before
      a delay (in the same way you can coalesce all writes before a page
      change is needed)

      regmap: Use reg_sequence for multi_reg_write / register_patch

      Separate the functionality using sequences of register writes from the
      functions that take register defaults. This change renames the arguments
      in order to support the extension of reg_sequence to take an optional
      delay to be applied after any given register in a sequence is written.
      This avoids adding an int to all register defaults, which could
      substantially increase memory usage for regmaps with large default tables.

      This also updates all the clients of multi_reg_write/register_patch.

      route settings. This patch adds snd_soc_of_parse_audio_prefix() for
      this purpose. It will be used with snd_soc_of_parse_audio_routing().

      regulator: 88pm800: Use regulator_nodes/of_match in the descriptor

      This patch is add regulator_nodes/of_match in the regulator
      descriptor for using information from DT instead of specific codes.

      With this patch, driver gets simplified,

        - No need to maintain "struct of_regulator_match" table
          and call of_regulator_match() fn.
        - No need for pm800_regulator_dt_init() fn, as it was only
          used for of_regulator_match().
        - probe() fn got simplified around regulator_config and regulator_desc
          initialization.

      regulator: 88pm800: Update driver to use devm_regulator_register fn

      This patch replaces standard regulator_register with
      devm_regulator_register() fn, as using devm_regulator_register() fn
      simplifies the driver return/exit path.

      As part of this update, patch also cleanups up all unnecessary changes
      which is result of this patch -

        - Remove _remove() fn, as devm_ variant takes care of it.
        - Remove pm800_regulators.regulators[] field, as it was only
          needed during cleanup, so we no longer need this.
          This also saved some amount of memory.

      Input: i8042 - add unmask_kbd_data option

      A big problem with the current i8042 debugging option is that it outputs
      data going to and from the keyboard by default. As a result, many dmesg
      logs uploaded by users will unintentionally contain sensitive information
      such as their password, as such it's probably a good idea not to output
      data coming from the keyboard unless specifically enabled by the user.

      dmaengine: ioatdma: Ignore IOAT devices under hotplug-capable PCI host 
bridge

      The dmaengine core assumes that async DMA devices will only be removed
      when they not used anymore, or it assumes dma_async_device_unregister()
      will only be called by dma driver exit routines. But this assumption is
      not true for the IOAT driver, which calls dma_async_device_unregister()
      from ioat_remove(). So current IOAT driver doesn't support device
      hot-removal because it may cause system crash to hot-remove an inuse
      IOAT device.

      To support CPU socket hot-removal, all PCI devices, including IOAT
      devices embedded in the socket, will be hot-removed. The idea solution
      is to enhance the dmaengine core and IOAT driver to support hot-removal,
      but that's too hard.

      This patch implements a hack to disable IOAT devices under hotplug-capable
      CPU socket so it won't break socket hot-removal.

      ARM: OMAP2+: Remove legacy booting support for Pandora

      We've been moving all omap2+ based systems to boot in device tree only
      mode for a few years now. Only omap3 has legacy booting support
      remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
      files for booting with device tree.

      This board has support for device tree based booting, and we've been
      printing warnings about the legacy booting being deprecated for a
      few merge cycles now. Let's attempt to remove the legacy booting
      for it.

      The reason for removing the legacy booting support now rather than
      later is we can simply revert this patch if necessary if we run
      into some unexpected issues that are not trivial to fix for the
      device tree based booting.

      pinctrl: sh-pfc: Convert to platform_get_*()

      If the pin function controller (which can be a GPIO controller) is
      instantiated before the interrupt controllers, due to the ordering in

      "interrupts-extended" property cannot be found yet:

          irq: no irq domain found for /interrupt-controller@e61c0000 !

      As the sh-pfc driver accesses the platform device's resources directly,
      it cannot find the (optional) IRQ resources, and thinks no interrupts
      are available. This may lead to failures later, when GPIOs are used as
      interupts:

          gpio-keys keyboard: Unable to claim irq 0; error -22
          gpio-keys: probe of keyboard failed with error -22

      To fix this, add support for deferred probing to sh-pfc, by converting
      the driver from direct platform device resource access to using the
      platform_get_resource() and platform_get_irq() helpers.

      Note that while this fixes the root cause worked around by commit
      e4ba0a9bddff3ba5 ("ARM: shmobile: r8a73a4: Move pfc node to work around
      probe ordering bug"), I strongly recommend against reverting the
      workaround now, as this would lead to lots of probe deferrals in drivers
      relying on pinctrl. This may be reconsidered once the DT code starts
      taking into account phandle dependencies during device instantation.

      gpio: rcar: Fine-grained Runtime PM support

      Currently gpio modules are runtime-resumed at probe time. This means the
      gpio module will be active all the time (except during system suspend,
      if not configured as a wake-up source).

      While an R-Car Gen2 gpio module retains pins configured for output at
      the requested level while put in standby mode, gpio registercannot be
      accessed while suspended.  Unfortunately pm_runtime_get_sync() cannot be
      called from all contexts where gpio register access is needed. Hence
      move the Runtime PM handling from probe/remove time to gpio request/free
      time, which is probably the best we can do.

      On r8a7791/koelsch, gpio modules 0, 1, 3, and 4 are now suspended during
      normal use (gpio2 is used for LEDs and regulators, gpio5 for keys, gpio6
      for SD-Card CD & WP, gpio7 for keys and regulators).

      Add a new cpufreq driver for Tegra124. Instead of using the PLLX as
      the CPU clocksource, switch immediately to the DFLL. It allows the use
      of higher clock rates, and will automatically scale the CPU voltage as
      well. Besides the CPU clocksource switch, we let the cpufreq-dt driver
      for all the cpufreq operations.

      This driver also relies on the DFLL driver to fill the OPP table for the
      CPU0 device, so that the cpufreq-dt driver knows what frequencies to

      clk: tegra: Introduce ability for SoC-specific reset control callbacks

      This patch allows SoC-specific CAR initialization routines to register
      their own reset_assert and reset_deassert callbacks with the common Tegra
      CAR code. If defined, the common code will call these callbacks when a
      reset control with number >= num_periph_banks * 32 is attempted to be 
asserted
      or deasserted respectively. Numbers greater than or equal to 
num_periph_banks * 32
      are used to avoid clashes with low numbers that are automatically mapped 
to
      standard CAR reset lines.

      Each SoC with these special resets should specify the defined reset 
control
      numbers in a device tree header file.

      clk: tegra: Add functions for parsing CVB tables

      Tegra CVB tables encode the relationship between operating voltage
      and optimal frequency as a function of the so-called speedo value.
      The speedo value is written to the on-chip fuses at the factory,
      which allows the voltage-frequency operating points to be calculated
      on an per-chip basis.

      Add utility functions to parse the Tegra-specific tables and export the
      voltage-frequency pairs to the generic OPP framework for other drivers
      to use.

      clk: tegra: Add closed loop support for the DFLL

      With closed loop support, the clock rate of the DFLL can be adjusted.

      The oscillator itself in the DFLL is a free-running oscillator whose
      rate is directly determined the supply voltage. However, the DFLL
      module contains logic to compare the DFLL output rate to a fixed
      reference clock (51 MHz) and make a decision to either lower or raise

      clk: tegra: Add library for the DFLL clock source (open-loop mode)

      Add shared code to support the Tegra DFLL clocksource in open-loop
      mode. This root clocksource is present on the Tegra124 SoCs. The
      DFLL is the intended primary clock source for the fast CPU cluster.

      This code is very closely based on a patch by Paul Walmsley from
      December (http://comments.gmane.org/gmane.linux.ports.tegra/15273),
      which in turn comes from the internal driver by originally created
      by Aleksandr Frid <afrid@xxxxxxxxxx>.

      Subsequent patches will add support for closed loop mode and drivers
      for the Tegra124 fast CPU cluster DFLL devices, which rely on this
      code.

      Merge branch 'protodown'

      Anuradha Karuppiah says:

      ====================
      net: Introduce protodown flag.

      User space daemons can detect errors in the network that need to be
      notified to the switch device drivers.

      Drivers can react to this error state by doing a phy-down on the
      switch-port which would result in a carrier-off locally and on the 
directly
      connected switch. Doing that would prevent loops and black-holes in the
      network.

      One such use case is the multi-chassis LAG application -

      1. The MLAG application runs on peer switches (say Switch0 and Switch1)
         synchronizing states, forwarding entries etc. between the two
         switches over the peer-link (this is a link directly connecting the
         two switches).
      2. An MLAG election process designates one of the switches as a primary
         (for e.g. Switch0 is primary and Switch1 is secondary).
      3. The peer link plays a critical role in allowing Switch0-Switch1 to
         function as a single LAG partner to the downstream dual-connected
         servers. When the peer-link between the switches goes down we have a
         split-brain situation. Switch0 and Switch1 are no longer in sync and
         are acting independently. This can result in traffic loops and
         traffic black-holing in the network.
      4. To prevent these problems the MLAG application on the secondary
         switch phy-downs the MLAG ports on detecting the peer-link down.
         This will be seen as a carrier down on servers that are
         dual-connected to Switch0 and Switch1.
      5. Specifically a dual-connected server will see a carrier-down on the
         port connected to the MLAG secondary, Switch1, and will stop using
         that port for traffic TX. So traffic black holing is prevented.

      v6 to v7:
         Removed some unnecessary code in response to review comments.

      v5 to v6:
         Replaced proto_flags with a simple proto_down boolean attribute in
         response to Dave's comments.

      v4 to v5:
         Changed the ip link display format for protodown to match the set as
         recommended by Stephen.

      v3 to v4:
         I have moved protodown out of IFF_XXX and introduced a separate
         proto_flags field with IF_PROTOF_DOWN bit being used by apps to notify
         switch port errors. This is in response to Stephen's comments that
         adding a new IFF_XXX may break user space.

         I have used rocker as the sample switch driver. And to test this
         functionality I used the qemu-rocker patch that Scott sent out in
         response to the v3 posting (needed to set link up/down when phy is
         enabled/disabled).

      v1 to v2:
         Based on Dave's suggestion I have moved out aggregating of error bits
         across applications to a user space framework. This patch now simply
         notifies an aggregated error bit to drivers enabling them to handle
         the error gracefully.

      ambient temperature or system running on UPS power with low UPS battery.
      DPO event is generated in response to admin initiated system shutdown
      request. Upon receipt of EPOW and DPO events the host kernel invokes
      orderly_poweroff() for performing graceful system shutdown.

      tools/power turbostat: fix parameter passing for forked command

      turbostat supports forked command when sampling cpu state. However,
      the forked command is not allowed to be executed with options, otherwise
      turbostat might regard these options as invalid turbostat options.

      For example:

      ./turbostat stress -c 4 -t 10
      ./turbostat: unrecognized option '-t'

      Intel Wired LAN Driver Updates 2015-07-14

      This series contains updates to i40e and i40evf only.

      Joe Stringer and Jesse Gross add a ndo_features_check function to ensure
      that the i40e driver does not try to offload packets that exceed 80 bytes
      in length.

      Anjali adds additional stats to track flow director ATR and SB current
      state and flow director flush count which will help the need for verbose
      debug logs with respect to flow director.  Also refines an error message
      to avoid confusion, so that it indicates what may have really happened
      when the init_shared_code() call possibly fails.

      Pawel adds new fields to the capabilities structures to handle Flex-10
      device/function capabilities which is needed to support Flex-10 configs.

      Jesse improves the transmit performance by added a prefetch for the
      next transmit descriptor to be used when we know there are more coming.

      Mitch modifies i40evf driver to handle/allow an abundance of vectors.
      Currently the driver only maps transmit and receive queues to a single
      MSI-X vector per queue if there are exactly enough vectors for this, but
      if we have too many vectors, it will fail and allocate queues to vectors
      in a suboptimal manner.  So change the condition check to allow for an
      excess number of vectors and won't use the extras.  Also update the
      driver to just return success if the user attempts to set a port VLAN on
      a VF that already has the same port VLAN configured, instead of going
      through unnecessary filter removals & adds.  Fix the MAC filters for VFs,
      which were being programmed with 0 for the VLAN value when there was no
      VLAN assigned.  Instead, we must use -1 to indicate that no VLAN is in
      use.  Fix the VF disable code, which was not properly cleaning up the VF
      and would leave the VF in an indeterminate state, so fix this by
      notifying the VF and then call the normal VF reset routine.  Fix the
      logic in the driver so that MAC filters are added and removed correctly
      and added a check for the driver's hardware MAC address so that this
      filter does not get removed incorrectly.

      Carolyn removes incorrect #ifdef's which should not have been added in
      the first place and with the #ifdef's removed, make the necessary
      changes in the driver to resolve compile errors.

      Greg updates the admin queue command header defines.

      ARM: OMAP2+: hwmod: add support for lock and unlock hooks

      Some IP blocks like RTC, needs an additional setting for writing to its
      registers. This is to prevent any spurious writes from changing the
      register values.

      This patch adds optional lock and unlock function pointers to
      the IP block's hwmod data. These unlock and lock function pointers
      are called by hwmod code before and after writing sysconfig registers.

      gianfar: Add Rx S/G

      This patch-set introduces scatter/gather support
      on the Rx side, addressing Rx path performance
      issues in the driver.
      Thanks.

      As an example, two boards connected back-to-back
      were used to measure the throughput, running the
      same kernel 4.1, before and after applying these
      patches.
      The netperf UDP_STREAM results below show that the
      bottleneck lies on the Rx side BEFORE applying the
      patches, and that the Rx throughput is even lower
      with a larger MTU.  AFTER applying the patches the
      Rx bottleneck is gone (Rx throughput matches the
      Tx one) and the RX throughput is not influenced by
      MTU size any longer (as expected).

      gianfar: Add paged allocation and Rx S/G

      The eTSEC h/w is capable of scatter/gather on the receive side
      too if MAXFRM > MRBLR, when the allowed maximum Rx frame size
      is set to be greater than the maximum Rx buffer size (MRBLR).
      It's about time the driver makes use of this h/w capability,
      by supporting fixed buffer sizes and Rx S/G.

      The buffer size given to eTSEC for reception is fixed to
      1536B (must be multiple of 64), which is the same default
      buffer size as before, used to accommodate standard MTU
      (1500B) size frames.  As before, eTSEC can receive frames of
      up to 9600B.  Individual Rx buffers are mapped to page halves
      (page size for eTSEC systems is 4KB).  The skb is built around
      the first buffer of a frame (using build_skb()).  In case the
      frame spans multiple buffers, the trailing buffers are added
      as Rx fragments to the skb.  The last buffer in frame is marked
      by the L status flag.  A mechanism is in place to reuse the pages
      owned by the driver (for Rx) for subsequent receptions.

      Supporting fixed size buffers allows the implementation of Rx S/G,
      which in turn removes the memory pressure issues the driver had
      before when MTU was set for jumbo frame reception.
      Also, in most cases, the Rx path becomes faster due to Rx page
      reusal, since the overhead of allocating new rx buffers is removed
      from the fast path.

      gianfar: Fix and cleanup rxbd status handling

      There are several (long standing) problems about how the status
      field of the rx buffer descriptor (rxbd) is currently handled on
      the error path:
      - too many unnecessary 16bit reads of the two halves of the rxbd
      status field (32bit), also resulting in overuse of endianness
      convesion macros;
      - "bdp->status = RXBD_LARGE" makes no sense, since the "large"
      flag is read only (only eTSEC can write it), and trying to clear
      the other status bits is also error prone in this context
      (most of the rx status bits are read only anyway).

      This is fixed with a single 32bit read of the "status" field,
      and then the appropriate 16bit shifting is applied to access
      the various status bits or the rx frame length. Also corrected
      the use of the RXBD_LARGE flag.

      Additional fix:
      "rx_over_errors" stat is incremented instead of "rx_crc_errors"
      in case of RXBD_OVERRUN occurrence.

      gianfar: Bundle Rx allocation, cleanup

      Use a more common consumer/ producer index design to improve
      rx buffer allocation.  Instead of allocating a single new buffer
      (skb) on each iteration, bundle the allocation of several rx
      buffers at a time.  This also opens the path for further memory
      optimizations.

      Remove useless check of rxq->rfbptr, since this patch touches
      rx pause frame handling code as well.  rxq->rfbptr is always
      initialized as part of Rx BD ring init.

      dt-bindings: brcmstb-gpio: document properties for wakeup

      Some brcmstb GPIO controllers can be used to wake from suspend, so use
      the de facto standard property 'wakeup-source' to mark the nodes of
      controllers with that capability.

      Also document interrupts-extended, which will be used for wakeup
      handling because the interrupt parent for the wake IRQ is different
      from the regular IRQ.

      While we're at it, a few more fixes: We don't actually use the
      "interrupt-names" property, so remove it from the listed optional
      properties and from the examples.  And since we're modifying the
      examples, also follow Brian's suggestions to:
      - change #gpio-cells, #interrupt-cells, and brcm,gpio-bank-widths from
        hex to dec
      - use phandles

      rcutorture: Add RCU-tasks qualifier to dereference

      Although RCU-tasks isn't really designed to support rcu_dereference()
      and list manipulation, that is how rcutorture tests it.  Which means
      that lockdep-RCU complains about the rcu_dereference_check() invocations
      because RCU-tasks doesn't have read-side markers.  This commit therefore
      creates a torturing_tasks() to silence the lockdep-RCU complaints from
      rcu_dereference_check() when RCU-tasks is being tortured.

      Number of items in rcu_capacity[] array is defined by macro

      RCU_NUM_LVLS items and eliminate MAX_RCU_LVLS. As result,
      in most cases the memory is conserved.

      rcu: Limit rcu_state::levelcnt[] to RCU_NUM_LVLS items

      Variable rcu_num_lvls is limited by RCU_NUM_LVLS macro.
      In turn, rcu_state::levelcnt[] array is never accessed
      beyond rcu_num_lvls. Thus, rcu_state::levelcnt[] is safe
      to limit to RCU_NUM_LVLS items.

      Since rcu_num_lvls could be changed during boot (as result
      of rcutree.rcu_fanout_leaf kernel parameter update) one might
      assume a new value could overflow the value of RCU_NUM_LVLS.
      However, that is not the case, since leaf-level fanout is only
      permitted to increase, resulting in rcu_num_lvls possibly to
      decrease.

      This update simplifies rcu_init_geometry() code flow

      The update relies on the fact num_rcu_lvl[] is never

      rcu: Panic if RCU tree can not accommodate all CPUs

      Currently a condition when RCU tree is unable to accommodate
      the configured number of CPUs is not permitted and causes
      a fall back to compile-time values. However, the code has no
      means to exceed the RCU tree capacity neither at compile-time
      nor in run-time. Therefore, if the condition is met in run-
      time then it indicates a serios problem elsewhere and should
      be handled with a panic.

      rcu: Change return type to bool

      Type-checking coccinelle spatches are being used to locate type mismatches
      between function signatures and return values in this case this produced:
      ./kernel/rcu/srcu.c:271 WARNING: return of wrong type
              int != unsigned long,

      srcu_readers_active() returns an int that is the sum of per_cpu unsigned
      long but the only user is cleanup_srcu_struct() which is using it as a
      boolean (condition) to see if there is any readers rather than actually
      using the approximate number of readers. The theoretically possible
      unsigned long overflow case does not need to be handled explicitly - if
      we had 4G++ readers then something else went wrong a long time ago.

      proposal: change the return type to boolean. The function name is left
                unchanged as it fits the naming expectation for a boolean.

      patch was compile tested for x86_64_defconfig (implies CONFIG_SRCU=y)

      DEBUG_LOCK_ALLOC=y is not a production setting, but it is
      not very unusual either. Many developers routinely

      Apart from being selected by hand, it is also auto-selected by
      PROVE_LOCKING "Lock debugging: prove locking correctness" and
      LOCK_STAT "Lock usage statistics" config options.
      LOCK STAT is necessary for "perf lock" to work.

      I wouldn't spend too much time optimizing it, but this particular
      function has a very large cost in code size: when it is deinlined,
      code size decreases by 830,000 bytes:

      seccomp: add ptrace options for suspend/resume

      This patch is the first step in enabling checkpoint/restore of processes
      with seccomp enabled.

      One of the things CRIU does while dumping tasks is inject code into them
      via ptrace to collect information that is only available to the process
      itself. However, if we are in a seccomp mode where these processes are
      prohibited from making these syscalls, then what CRIU does kills the task.

      This patch adds a new ptrace option, PTRACE_O_SUSPEND_SECCOMP, that 
enables
      a task from the init user namespace which has CAP_SYS_ADMIN and no seccomp
      filters to disable (and re-enable) seccomp filters for another task so 
that
      they can be successfully dumped (and restored). We restrict the set of
      processes that can disable seccomp through ptrace because although today
      ptrace can be used to bypass seccomp, there is some discussion of closing
      this loophole in the future and we would like this patch to not depend on
      that behavior and be future proofed for when it is removed.

      Note that seccomp can be suspended before any filters are actually
      installed; this behavior is useful on criu restore, so that we can suspend
      seccomp, restore the filters, unmap our restore code from the restored
      process' address space, and then resume the task by detaching and have the
      filters resumed as well.

      v2 changes:

      * require that the tracer have no seccomp filters installed
      * drop TIF_NOTSC manipulation from the patch
      * change from ptrace command to a ptrace option and use this ptrace option
        as the flag to check. This means that as soon as the tracer
        detaches/dies, seccomp is re-enabled and as a corrollary that one can 
not
        disable seccomp across PTRACE_ATTACHs.

      v3 changes:

      * get rid of various #ifdefs everywhere
      * report more sensible errors when PTRACE_O_SUSPEND_SECCOMP is incorrectly
        used

      v4 changes:

      * get rid of may_suspend_seccomp() in favor of a capable() check in ptrace
        directly

      v5 changes:

      * check that seccomp is not enabled (or suspended) on the tracer

      netfilter: xtables: don't save/restore jumpstack offset

      In most cases there is no reentrancy into ip/ip6tables.

      For skbs sent by REJECT or SYNPROXY targets, there is one level
      of reentrancy, but its not relevant as those targets issue an absolute
      verdict, i.e. the jumpstack can be clobbered since its not used
      after the target issues absolute verdict (ACCEPT, DROP, STOLEN, etc).

      So the only special case where it is relevant is the TEE target, which
      returns XT_CONTINUE.

      This patch changes ip(6)_do_table to always use the jump stack starting
      from 0.

      When we detect we're operating on an skb sent via TEE (percpu
      nf_skb_duplicated is 1) we switch to an alternate stack to leave
      the original one alone.

      Since there is no TEE support for arptables, it doesn't need to
      test if tee is active.

      The jump stack overflow tests are no longer needed as well --
      since ->stacksize is the largest call depth we cannot exceed it.

      A much better alternative to the external jumpstack would be to just
      declare a jumps[32] stack on the local stack frame, but that would mean
      we'd have to reject iptables rulesets that used to work before.

      Another alternative would be to start rejecting rulesets with a larger
      call depth, e.g. 1000 -- in this case it would be feasible to allocate the
      entire stack in the percpu area which would avoid one dereference.

      We want to ensure only one duplicate is sent, so both will

      The other use case is detection of recursive call to xtables, but since

      The {arp,ip,ip6tables} jump stack is currently sized based
      on the number of user chains.

      However, its rather unlikely that every user defined chain jumps to the

      chain depths.

      The stacksize is then set to the largest chain depth seen.

      netfilter: Per network namespace netfilter hooks.

      - Add a new set of functions for registering and unregistering per
        network namespace hooks.

      - Modify the old global namespace hook functions to use the per
        network namespace hooks in their implementation, so their remains a
        single list that needs to be walked for any hook (this is important
        for keeping the hook priority working and for keeping the code
        walking the hooks simple).

      - Only allow registering the per netdevice hooks in the network
        namespace where the network device lives.

      - Dynamically allocate the structures in the per network namespace
        hook list in nf_register_net_hook, and unregister them in
        nf_unregister_net_hook.

        Dynamic allocate is required somewhere as the number of network
        namespaces are not fixed so we might as well allocate them in the
        registration function.

        The chain of registered hooks on any list is expected to be small so
        the cost of walking that list to find the entry we are unregistering
        should also be small.

        Performing the management of the dynamically allocated list entries
        in the registration and unregistration functions keeps the complexity
        from spreading.

      drm/i915: Invert fastboot check

      Fastboot should only downgrade a modeset if we have a match, not be
      used to upgrade to a full modeset. Otherwise we can only use it in a
      very restricted way: Initial modeset when the request mode is the
      preferred one of the panel and there's still a pfit active. And that
      only works because our mode_from_pipe_config fills in the wrong mode
      (it takes the adjusted mode, not the requested one).

      But we want fast modesets everywhere even after boot-up (especially
      for testing, but not only there). Hence we need to be able to make any
      modeset a fast one, which means we need to invert the logic and
      optionally downgrade a modeset.

      Note that this needs ->connector_changed split out from ->mode_changed
      otherwise it's not going to work (because we might loose a modeset
      because connectors changed but otherwise the config matches). As soon
      as that's merged we can drop the i915.fastboot check from this code.

      Also make sure that we don't accidentally clear any_ms and that we add
      the planes for any kind of modeset.

      Finally rename fastboot to fastset (yeah it's a silly name) since this
      really isn't about booting all that much.

      drm/i915: Clarify logic for initial modeset

      Currently we both set mode->private_flags to some value and also use
      the pipe_config quirk. But since the pipe_config quirk isn't tied to
      the lifetime of the mode object we need to check both.

      Simplify this by only using mode.private_flags and stop using the
      INHERITED_MODE quirk. Also for clarity add an explicit #define for
      that driver priavete mode flag.

      By using crtc_state->mode_changed we can also remove the recalc local

      We needed this originally for updating pagetables in plane commit

      drm/i915: Enable WA batch buffers for Gen9

      This patch only enables support for Gen9, the actual WA will be
      initialized in subsequent patches.

      The WARN that we use to warn user if WA batch support is not available
      for a particular Gen is replaced with DRM_ERROR as warning here doesn't
      really add much value.

      v2: include all infrastructure bits in this patch so that subsequent
      changes only correspond the WA added (Chris)

      Note running checkpatch.pl with '--strict' catches more
      of these errors along with cases where spacing is optional
      but preferred. Take care of these in a future patch.

      staging: vme_user: allow large read()/write()

      This changes large master transfers to do shorter read/write rather than
      return -EINVAL. User space will now be able to optimistically request a
      large transfer and get at least some data.

      This also removes comments suggesting on how to implement large
      transfers. Current vme_master_* read and write implementations use CPU
      copies that don't produce burst PCI accesses and subsequently no block
      transfer on VME bus. In the end overall performance is quiet low and it
      can't be fixed by doing direct copy to user space. Much easier solution
      would be to just reuse kernel buffer.

      staging: ion: debugfs to shrink pool

      This patch enables debugfs file /sys/kernel/debug/ion/heaps/system_shrink
      to shrink pool and get pool size. This technically enables debugfs
      shrinking for all heaps, not just the system heap although the system heap
      is the only one with a shrinker right now. It is already implemented
      but not complete. This patch completes and enables it.

      Reading the file returns pool size
      in page unit and writing the number of pages shrinks pool.
      It flushes all pages to write zero at the file.

      staging: ion: shrink page-pool by page unit

      This patch shrink page-pool by page unit.

      The system shrinker calls ion_heap_shrink_count() to get nr_to_scan,
      and pass it to ion_heap_shrink_scan().
      The problem is the return value of ion_heap_shrink_count() is the number
      of pages but ion_system_heap_shrink(), which is called by
      ion_heap_shrink_scan(), gets the number of chunk.

      The main root of this is that ion_page_pool_shrink() returns page count
      via ion_page_pool_total() if it have to check pool size. But it frees
      chunks of pages if it have to free pools.

      This patch first fix ion_page_pool_shrink() to count only pages,
      not chunks. And then ion_system_heap_shrink() to work on pages.

      Use eth_zero_addr to assign the zero address to the given address
      array instead of memset when second argument is address of zero.
      Note that the 6 in the third argument of memset appears to represent
      an ethernet address size (ETH_ALEN).

      The Coccinelle semantic patch that makes this change is as follows:

      // <smpl>
      @eth_zero_addr@
      expression e;

      Some quirks search for a HyperTransport capability and use a hard-coded

      Staging: rtl8192u: Replace memset with eth_zero_addr

      Use eth_zero_addr to assign the zero address to the given address
      array instead of memset when second argument is address of zero.
      Note that the 6 in the third argument of memset appears to represent
      an ethernet address size (ETH_ALEN).

      The Coccinelle semantic patch that makes this change is as follows:

      // <smpl>
      @eth_zero_addr@
      expression e;

      -memset(e,0x00,6);

      ARM: dts: ventana: add UHS-I support for Ventana boards

      UHS-I support is available on Ventana boards with micro-SD sockets 
depending
      on the board revision. To support this pinctl states for 100Mhz and 200MHz
      must be added as well as pinmux of the VSELECT signal. In order to support
      UHS-I the I/O rail of the 4-bit data bus must be switchable between 1.8V
      and 3.3V.

      By adding the no-1-8-v property, which disables UHS-I support, we allow 
the
      bootloader to be in charge of selecting which boards have this capability
      by removing that property if the board model/revision implement the 
support.

      Additionally we will remove NANDF_CS1 here from the nand pinmux group as 
the
      second chip-select is not used on any ventana boards and this is the pad
      that is used for SD3_VELECT.

      staging: unisys: fix random hangs with network stress in visornic

      We learned that it was possible for the core networking code to call
      visornic_xmit() within ISR context, resulting in the need for us to
      use spin_lock_irqsave() / spin_lock_irqrestore() to lock accesses to our
      virtual device channels.

      Without the correct locking added in this patch, random hangs would occur
      on typical kernels while stressing the netork.  When using a kernel with
      CONFIG_DEBUG_SPINLOCK=y, a stackdump would occur at the time of the hang
      reporting:

          BUG: spinlock recursion on CPU#0, vnic_incoming/<pid>

      (see below for more details)

      We considered the possibility of adding a protocol between a visordriver
      and visorbus where the visordriver could specify which type of locking it
      required for its virtual device channels (essentially indicating whether
      or not it was possible for the channel to be accessed in ISR context), but
      decided this extra complexity was NOT needed, and that channel queues
      should always be accessed with the most-stringent locking.  So that is
      what is implemented in this commit.

      Below is an example stackdump illustrating the spinlock recursion that is
      fixed by this commit.  Note that we are first in virtnic_rx() writing to
      the device channel when an APIC timer interrupt occurs.  Within the core
      networking code, net_rx_action() calls process_backlog(), which eventually
      lands up back up in virtnic_xmit() in the code attempting to also write to

      staging: unisys: fix random memory corruption in visorchannel_write()

      visorchannel_write() and it's user visorbus_write_channel() are
      exported, so all visorbus function drivers (i.e., drivers that call
      visorbus_register_visor_driver()) are potentially affected by the bug.

      Because of pointer-arithmetic rules, the address being written to in the
      affected code was actually at byte offset:

          sizeof(struct channel_header) * offset

      instead of just <offset> bytes as intended.

      The bug could cause some very difficult-to-diagnose symptoms.  The
      particular problem that led me on this chase was a kernel fault that
      would occur during 'insmod visornic' after a previous 'rmmod visornic',
      where we would fault during netdev_register_kobject() within
      pm_runtime_set_memalloc_noio() while traversing a device list, which
      occurred because dev->parent for the visorbus device had become
      corrupted.

      staging: unisys: visornic: prevent erroneous kfree of devdata pointer

      A struct visornic_devdata for each visornic device is actually allocated 
as
      part of alloc_etherdev(), here in visornic_probe():

          netdev = alloc_etherdev(sizeof(struct visornic_devdata));

      But code in devdata_release() was treating devdata as a pointer that 
needed
      to be kfree()d!  This was causing all sorts of weird behavior after doing
      an rmmod of visornic, both because free_netdev() was actually freeing the
      memory used for devdata, and because devdata wasn't pointing to
      dynamically-allocated memory in the first place.

      The kfree(devdata) and the kref that tracked devdata's usage have been
      appropriately deleted.

      staging: unisys: visornic: correctly clean up device on removal

      visornic_remove() is called to logically detach the visornic driver from a
      visorbus-supplied device, which can happen either just prior to a
      visorbus-supplied device disappearing, or as a result of an rmmod of
      visornic.  Prior to this patch, logic was missing to properly clean up for
      this removal, which was fixed via the following changes:

      * A going_away flag is now used to interlock between device destruction 
and
        workqueue operations, protected by priv_lock.  I.e., setting
        going_away=true under lock guarantees that no new work items can get
        queued to the work queues.  going_away=true also short-circuits other
        operations to enable device destruction to proceed.

      * Missing clean-up operations for the workqueues, netdev, debugfs entries,
        and the worker thread were added.

      * Memory referenced from the visornic private devdata struct is now freed
        as part of devdata destruction.

      staging: unisys: add error messages to visornic

      Add error message to genuine rare error paths, and debug messages
      to enable relatively non-verbose tracing of code paths

      You can enable debug messages by including this on the kernel command 
line:

          visornic.dyndbg=+p

      or by this from the command line:

          echo "module visornic +p" > <debugfs>/dynamic_debug/control

      Refer to Documentation/dynamic-debug-howto.txt for more details.

      In addition to the new debug and error messages, a message like the
      following will be logged every time a visornic device is probed, which
      will enable you to map back-and-forth between visorbus device names
      (e.g., "vbus2:dev0") and netdev names (e.g., "eth0"):

          visornic vbus2:dev0: visornic_probe success netdev=eth0

      With this patch and visornic debugging enabled, you should expect to see
      messages like the following in the most-common scenarios:

      * driver loaded:

            visornic_init

      * device probed:

            visornic vbus2:dev0: visornic_probe
            visor_thread_start
            visor_thread_start success

      * network interface configured (ifconfig):

            net eth0: visornic_open
            net eth0: visornic_enable_with_timeout
            net eth0: visornic_enable_with_timeout success

      staging: unisys: neglect to NULL rcvbuf pointer

      Neglect to NULL rcvbuf pointer array could result in faults later

      This problem would exhibit itself as a fault when when attempting to stop
      any visornic device (i.e., in visornic_disable_with_timeout() or
      visornic_serverdown_complete()) that had never been started (i.e., for
      which init_rcv_bufs() had never been called).  Because the array of rcvbuf
      was never cleared to NULLs, we would mistakenly attempt to call 
kfree_skb()
      on garbage memory.

      Prevent faults in visornic_pause, visornic_resume(), and visornic_remove()

      Prior to this patch, any call to visornic_pause(), visornic_resume(), or
      visornic_remove() would fault, due to dev_set_drvdata() never having been
      called to stash our struct visornic_devdata * into the device's drvdata.
      I.e., all calls to dev_get_drvdata() were returning NULL, meaning a fault
      was soon to follow.

      staging: unisys: visornic: correct visornic_pause

      Correct visornic_pause() to indicate completion asynchronously rather
      than in-line

      Previously, visornic_pause() (called to stop the device due to IOVM 
service
      partition recovery) was calling the passed complete_func() in-line, rather
      than delaying the calling until after the device had actually been 
stopped.

      The behavior has been corrected so that the calling of the complete_func()
      is now delayed until after the stopping of the device has been completed 
in
      visornic_serverdown_complete(), which runs asynchronously via the 
workqueue
      visornic_serverdown_workqueue.

      staging: unisys: prevent faults processing messages

      Prevent faults processing messages for devices that no driver has yet
      registered to handle.

      Previously, code of the form:

          drv = to_visor_driver(dev->device.driver);
          if (!drv)
              goto away;

      was not having the desired intent, because to_visor_driver() was
      essentially returning garbage if its argument was NULL.  The only existing
      case of this is in initiate_chipset_device_pause_resume(), which is called
      during IOVM service partition recovery.  We were thus faulting when IOVM
      service partition recovery was initiated on a bus that had at least one
      device for which no function driver had registered
      (visorbus_register_visor_driver).

      staging: unisys: respond to msgs post device_create

      Fix problem that prevents us from responding to any device message after
      device_create.

      By neglecting to NULL out pending_msg_hdr after the device_create 
response,
      we were effectively preventing any subsequent messages to the device from
      working, because device_epilog() will correctly bail out early if it sees
      that pending_msg_hdr is still set non-NULL, as that is an indicator to 
mean
      that an unanswered message is still outstanding.

      This problem was discovered as part of testing IOVM service partition
      recovery, because device_epilog() was in fact bailing out when it was
      called from my_device_changestate(), which of course prevented us from
      transitioning the device to the paused state.  However, the incorrect
      behavior would occur for ANY subsequent command directed at the device,
      not just for changestate.

      For PBLE resource management, it is more efficient for it to manage its

      driver for PBLE resource.

      The i40e_remove_pd_bp() is also modified to not free pre-allocated pages 
and
      free only ones which were allocated in i40e_add_pd_table_entry().

      i40evf: don't delete all the filters

      Due to an inverted conditional, the driver was marking all of its MAC
      filters for deletion every time set_rx_mode was called. Depending upon
      the timing of the calls to set_rx_mode and the processing of the admin
      queue, the driver would (accidentally) end up with a varying number of
      functional filters.

      Correct this logic so that MAC filters are added and removed correctly.
      Add a check for the driver's "hardware" MAC address so that this filter
      doesn't get removed incorrectly.

      MAC filters for VFs were being programmed with 0 for the VLAN value when
      there was no VLAN assigned. This is incorrect and actually assigns the
      VF to VLAN 0. Instead, we must use -1 to indicate that no VLAN is in
      use. This change programs the filters correctly and gets rid of a bogus
      error message when setting a port VLAN on an active VF.

      i40evf: Allow for an abundance of vectors

      The driver currently only maps TX and RX queues to a single MSI-X vector
      per queue pair if there are exactly enough vectors for this.
      Unfortunately, if we have too many vectors it will fail and allocate
      queues to vectors in a suboptimal manner. Change the condition check to
      allow for excess vectors. In this case, the extras just won't be used.

      staging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN

      If the "comedi" module has been loaded with the
      "comedi_num_legacy_minors" module parameter set to a non-zero value,
      some reserved comedi devices get created.  These can be attached to a
      low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
      which checks for the `CAP_SYS_ADMIN` capability.  Of course, the comedi
      device needs to be opened before the ioctl command can be sent.  If the
      comedi device is unattached, `comedi_open()` currently requires the
      `CAP_NET_ADMIN` capability.  It makes more sense to just require the
      `CAP_SYS_ADMIN` capability here, so change it.

      For the curious, commit a8f80e8ff94e ("Networking: use CAP_NET_ADMIN
      when deciding to call request_module") changed this capability from
      `CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
      relevant here.  The original `CAP_SYS_MODULE` capability was due to the
      function having some code to request a module using a "char-major-%i-%i"
      alias, but that was never compiled in and was removed by commit
      f30f2c2d417b ("staging: comedi: remove check for CONFIG_KMOD").

      staging: comedi: cb_pcimdas: add external analog output ranges

      The analog output range is not programmable, but the ranges for each of
      the two analog output channels are settable via jumpers.  These jumper
      settings are not readable by the driver.  The driver
      provides a range table containing all the possible internal ranges
      (+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
      application (although any range selected by the application that differs
      from the jumper settings will not produce the expected voltage output).

      The range table does not cover all possible ranges of the analog output
      channels.  The jumpers also allow an external reference voltage between
      0 and 10V to be used as bipolar or unipolar output range.  Add a couple
      more ranges to the end of the range table to define these two external
      ranges.

      PCI: Add pcie_downstream_port() (true for Root and Switch Downstream 
Ports)

      As used in the PCIe spec, "Downstream Port" includes both Root Ports and
      Switch Downstream Ports.  We sometimes checked for PCI_EXP_TYPE_DOWNSTREAM
      when we should have checked for PCI_EXP_TYPE_ROOT_PORT or
      PCI_EXP_TYPE_DOWNSTREAM.

      For a Root Port without a slot, the effect of this was that using
      pcie_capability_read_word() to read PCI_EXP_SLTSTA returned zero instead 
of
      showing the Presence Detect State bit hardwired to one as the PCIe Spec,
      r3.0, sec 7.8, requires.  (This read is completed in software because
      previous PCIe spec versions didn't require PCI_EXP_SLTSTA to exist at 
all.)

      Nothing in the kernel currently depends on this (pciehp only reads
      PCI_EXP_SLTSTA on ports with slots), so this is a cleanup and not a
      functional change.

      Add a pcie_downstream_port() helper function and use it.

      cgroup: implement the PIDs subsystem

      Adds a new single-purpose PIDs subsystem to limit the number of
      tasks that can be forked inside a cgroup. Essentially this is an
      implementation of RLIMIT_NPROC that applies to a cgroup rather than a
      process tree.

      However, it should be noted that organisational operations (adding and
      removing tasks from a PIDs hierarchy) will *not* be prevented. Rather,
      the number of tasks in the hierarchy cannot exceed the limit through
      forking. This is due to the fact that, in the unified hierarchy, attach
      cannot fail (and it is not possible for a task to overcome its PIDs
      cgroup policy limit by attaching to a child cgroup -- even if migrating
      mid-fork it must be able to fork in the parent first).

      PIDs are fundamentally a global resource, and it is possible to reach
      PID exhaustion inside a cgroup without hitting any reasonable kmemcg
      policy. Once you've hit PID exhaustion, you're only in a marginally
      better state than OOM. This subsystem allows PID exhaustion inside a
      cgroup to be prevented.

      cgroup: allow a cgroup subsystem to reject a fork

      Add a new cgroup subsystem callback can_fork that conditionally
      states whether or not the fork is accepted or rejected by a cgroup
      policy. In addition, add a cancel_fork callback so that if an error
      occurs later in the forking process, any state modified by can_fork can
      be reverted.

      Allow for a private opaque pointer to be passed from cgroup_can_fork to
      cgroup_post_fork, allowing for the fork state to be stored by each
      subsystem separately.

      Also add a tagging system for cgroup_subsys.h to allow for CGROUP_<TAG>
      enumerations to be be defined and used. In addition, explicitly add a
      CGROUP_CANFORK_COUNT macro to make arrays easier to define.

      This is in preparation for implementing the pids cgroup subsystem.

      PCI: Shift PCI_CLASS_NOT_DEFINED consistently with other classes

      The PCI class in dev->class is a three-byte value comprising a base class,
      sub-class, and interface type.  PCI_CLASS_NOT_DEFINED includes the base
      class and sub-class, but not the interface type, so it should be shifted 
to
      make space for the interface.  It happens that PCI_CLASS_NOT_DEFINED is
      zero, so it doesn't matter in the end, but we should still use it
      consistently with other class definitions.

      Treat PCI_CLASS_NOT_DEFINED as a base class/sub-class value that should
      appear in bits 8-23 of dev->class.

      PCI: Revert aeb30016fec3 ("PCI: add Intel USB specific reset method")

      Revert aeb30016fec3 ("PCI: add Intel USB specific reset method").

      We checked for "dev->class == PCI_CLASS_SERIAL_USB", but dev->class
      contains the entire three-byte base class/sub-class/interface, while
      PCI_CLASS_SERIAL_USB is only the two-byte base class/sub-class.

      This error meant that we used the Intel device-specific reset on devices
      with class code 0x000c03 instead of those with class code 0x0c03xx.
      0x000c03 is a reserved value in the 0x00 backwards compatibility base
      class and shouldn't match any devices, so I think 
reset_intel_generic_dev()
      always failed.

      I considered adding a shift, but I can't test it, so it's as likely to
      break something as to fix something.

      PCI: Fix generic NCR 53c810 class code quirk

      In the generic quirk fixup_rev1_53c810(), added by a5312e28c195 ("[PATCH]
      PCI: NCR 53c810 quirk"), we assigned "class = PCI_CLASS_STORAGE_SCSI".  
But
      PCI_CLASS_STORAGE_SCSI is only the two-byte base class/sub-class and needs
      to be shifted to make space for the low-order interface byte.

      Furthermore, we had a similar quirk, pci_fixup_ncr53c810(), for arch/x86,
      which assigned class correctly.  The arch code is linked before the PCI
      core, so arch quirks run before generic quirks.  Therefore, on x86, the 
x86
      arch quirk ran first, and the generic quirk did nothing because it saw 
that
      dev->class was already set.  But on other arches, the generic quirk set 
the
      wrong class code.

      Fix the generic quirk to set the correct class code and remove the
      now-unnecessary x86-specific quirk.

      drm/i915: Readout initial hw mode.

      drm/i915: Readout initial hw mode, v2.

      Atomic requires a mode blob when crtc_state->enable is true, or
      you get a huge warn_on.

      With a few tweaks the mode we read out from hardware could be used
      as the real mode without a modeset, but this requires too much
      testing, so for now force a modeset the first time the mode blob's
      updated.

      This preserves the old behavior, because previously we never set
      the initial mode, which always meant that a modeset happened
      when the mode was first set.

      Changes since v1:
      - Add a description in intel_modeset_readout_hw_state of how the
        recalculation is done.

      drm/i915: Added Programming of the MOCS

      This change adds the programming of the MOCS registers to the gen 9+
      platforms. The set of MOCS configuration entries introduced by this
      patch is intended to be minimal but sufficient to cover the needs of
      current userspace - i.e. a good set of defaults. It is expected to be
      extended in the future to provide further default values or to allow
      userspace to redefine its private MOCS tables based on its demand for
      additional caching configurations. In this setup, userspace should
      only utilize the first N entries, higher entries are reserved for
      future use.

      It creates a fixed register set that is programmed across the different
      engines so that all engines have the same table. This is done as the
      main RCS context only holds the registers for itself and the shared
      L3 values. By trying to keep the registers consistent across the
      different engines it should make the programming for the registers
      consistent.

Turner)
      v3:
      - Make the tables "slightly" more readable. (Damien Lespiau)

      Instead of doing ad-hoc checks we already have a way of checking
      if the state is compatible or not. Use this to force a modeset.

      Only during modesets, or with PIPE_CONFIG_QUIRK_INHERITED_MODE

      Add a r8a7779-specific callback to initialize CCF and
      clocksources. With this in place we are one step closer
      to be able to use r8a7779 without C board code.

      Also add a multiplatform wrapper to avoid breaking the
      r8a7779 marzen legacy case.

      In addition to the regular mux configuration such as mux mode 1,
      2 etc, certain pins of DRA7 require to have "virtual mode" also
      programmed. This allows for predefined delay characteristics to
      be used by the SoC to meet timing characterstics needed for the
      interface.

      Provide easy to use macro to do the same.

      It is important to note that the official TI guidelines recommend
      to do as minimal pin reconfiguration beyond the bootloader given
      the design of the hardware involved which can result in substantial
      glitches which may impair functionality of certain peripherals.

      Some Overo COM models include NAND flash in the on-board

      Most commonly, this is 512MB NAND from the Micron MT29C4G96MAZ family
      but, as discussed [1], several different sized are possible. To
      support different sizes, the last partition should fill to the end of
      the chip (i.e. MTDPART_SIZ_FULL).

           void *cd = irq_get_chip_data(irq_data->irq);

      because that results in cd = irq_data->chip_data, but goes through a
      redundant lookup of the irq_data. Use irq_data directly.

      crypto: seqiv - Replace seqniv with seqiv

      This patch replaces the seqniv generator with seqiv when the
      underlying algorithm understands the new calling convention.

      This not only makes more sense as now seqiv is solely responsible
      for IV generation rather than also determining how the IV is going
      to be used, it also allows for optimisations in the underlying
      implementation.  For example, the space for the IV could be used
      to add padding for authentication.

      This patch also removes the unnecessary copying of IV to dst
      during seqiv decryption as the IV is part of the AD and not cipher
      text.

      'Deferred' bit. So do not print 'CE' on a deferred error.

      Refer to AMD Error Scope Hierarchy table in a newer BKDG (example:
      49125_15h_Models_30h-3Fh_BKDG.pdf, section "RAS Features").

      clk: st: Fix error paths and allocation style

      The error paths in this file leak memory and mappings and test
      for pointers being valid after dereferencing them. Fix these
      problems and properly free resources on errors. Fix some
      stylistic things too like using sizeof(*ptr) and fitting more
      code on a single line. Note that we don't unregister clocks here.
      That needs a clk_composite_unregister() API that we don't have
      right now.

      bridge: mdb: add vlan support for user entries

      Until now all user mdb entries were added in vlan 0, this patch adds
      support to allow the user to specify the vlan for the entry.
      About the uapi change a hole in struct br_mdb_entry is used so the size
      and offsets are kept the same (verified with pahole and tested with older
      iproute2).

      Example:
      $ bridge mdb
      dev br0 port eth1 grp 239.0.0.1 permanent vlan 2000
      dev br0 port eth1 grp 239.0.0.1 permanent vlan 200

      ebpf: remove self-assignment in interpreter's tail call

      ARG1 = BPF_R1 as it stands, evaluates to regs[BPF_REG_1] = regs[BPF_REG_1]
      and thus has no effect. Add a comment instead, explaining what happens and
      why it's okay to just remove it. Since from user space side, a tail call 
is
      invoked as a pseudo helper function via bpf_tail_call_proto, the verifier
      checks the arguments just like with any other helper function and makes
      sure that the first argument (regs[BPF_REG_1])'s type is ARG_PTR_TO_CTX.

      net: Build IPv6 into kernel by default

      This patch makes the default to build IPv6 into the kernel. IPv6
      now has significant traction and any remaining vestiges of IPv6
      not being provided parity with IPv4 should be swept away. IPv6 is now
      core to the Internet and kernel.

      Points on IPv6 adoption:

      - Per Google statistics, IPv6 usage has reached 7% on the Internet
        and continues to exhibit an exponential growth rate
        https://www.google.com/intl/en/ipv6/statistics.html
      - Just a few days ago ARIN officially depleted its IPv4 pool
      - IPv6 only data centers are being successfully built
        (e.g. at Facebook)

      This patch changes the IPv6 Kconfig for IPV6. Default for CONFIG_IPV6
      is set to "y" and the text has been updated to reflect the maturity of
      IPv6.

      Impact:

      Under some circumstances building modules in to kernel might have a
      performance advantage. In my testing, I did notice a very slight
      improvement.

      This will obviously increase the size of the kernel image. In my
      configuration I see:

      IPv6 as module:

         text    data     bss     dec     hex filename
      9703666 1899288  933888 12536842         bf4c0a vmlinux

      IPv6 built into kernel

        text     data     bss     dec     hex filename
      9436490 1879600  913408 12229498         ba9b7a vmlinux

      Which increases text size by ~270K (2.8% increase in size for me). If
      image size is an issue, presumably for a device which does not do IP
      networking (IMO we should be discouraging IPv4-only devices), IPV6 can
      be disabled or still built as a module.

      selinux: initialize sock security class to default value

      Initialize the security class of sock security structures
      to the generic socket class.  This is similar to what is
      already done in inode_alloc_security for files.  Generally
      the sclass field will later by set by socket_post_create
      or sk_clone or sock_graft, but for protocol implementations
      that fail to call any of these for newly accepted sockets,
      we want some sane default that will yield a legitimate
      avc denied message with non-garbage values for class and
      permission.

      selinux: reduce locking overhead in inode_free_security()

      The inode_free_security() function just took the superblock's isec_lock
      before checking and trying to remove the inode security struct from the
      linked list. In many cases, the list was empty and so the lock taking
      is wasteful as no useful work is done. On multi-socket systems with
      a large number of CPUs, there can also be a fair amount of spinlock
      contention on the isec_lock if many tasks are exiting at the same time.

      This patch changes the code to check the state of the list first before
      taking the lock and attempting to dequeue it. The list_del_init()
      can be called more than once on the same list with no harm as long
      as they are properly serialized. It should not be possible to have
      inode_free_security() called concurrently with list_add(). For better
      safety, however, we use list_empty_careful() here even though it is
      still not completely safe in case that happens.

      selinux: extended permissions for ioctls

      Add extended permissions logic to selinux. Extended permissions
      provides additional permissions in 256 bit increments. Extend the
      generic ioctl permission check to use the extended permissions for
      per-command filtering. Source/target/class sets including the ioctl
      permission may additionally include a set of commands. Example:

      allowxperm <source> <target>:<class> ioctl unpriv_app_socket_cmds
      auditallowxperm <source> <target>:<class> ioctl priv_gpu_cmds

      Where unpriv_app_socket_cmds and priv_gpu_cmds are macros
      representing commonly granted sets of ioctl commands.

      When ioctl commands are omitted only the permissions are checked.
      This feature is intended to provide finer granularity for the ioctl
      permission that may be too imprecise. For example, the same driver
      may use ioctls to provide important and benign functionality such as
      driver version or socket type as well as dangerous capabilities such
      as debugging features, read/write/execute to physical memory or
      access to sensitive data. Per-command filtering provides a mechanism
      to reduce the attack surface of the kernel, and limit applications
      to the subset of commands required.

      The format of the policy binary has been modified to include ioctl
      commands, and the policy version number has been incremented to
      POLICYDB_VERSION_XPERMS_IOCTL=30 to account for the format
      change.

      The extended permissions logic is deliberately generic to allow
      components to be reused e.g. netlink filters

      The old warp board revision had hardware issues that prevented
      the RTS/CTS lines to work with the Bluetooth module.

      Tha latest rev1.12 fixes this problem, so now we should better use

      the CONFIG_BT_HCIUART_3WIRE option.

      regmap: Add better support for devices without readback support

      Currently regmap requires that a reg_read callback is supplied, otherwise 
a
      warning is emitted each time regmap_read() is called. This means a device
      or bus without readback support needs to supply dummy reg_read callback.
      Apart from that regmap_read() will still work fine if a cache is used.

      Remove the warning and let regmap_readable() return false if not reg_read
      callback is supplied. This means a device no longer has to supply a dummy
      callback if it does not support readback and it also doesn't have to have 
a
      readable_reg callback that always returns false since this is now 
implicit.

      drm/i915: Update PM interrupts before updating the freq

      Currently we update the freq before masking the interrupts, which can
      allow new interrupts to occur before the frequency has changed. These
      extra interrupts might waste some cpu cycles. This patch corrects
      this by masking interrupts prior to updating the frequency.

      Note from Chris:
      "Well it won't waste CPU cycles as the interrupt is also masked by the
      threshold limits, but there should be no harm at all in reordering the
      patch so, and it does make a certain amount of sense."

      ARM: OMAP2+: Remove legacy booting support for LogicPD Torpedo

      We've been moving all omap2+ based systems to boot in device tree only
      mode for a few years now. Only omap3 has legacy booting support
      remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
      files for booting with device tree.

      This board has support for device tree based booting, and we've been
      printing warnings about the legacy booting being deprecated for a
      few merge cycles now. Let's attempt to remove the legacy booting
      for it.

      The reason for removing the legacy booting support now rather than
      later is we can simply revert this patch if necessary if we run
      into some unexpected issues that are not trivial to fix for the
      device tree based booting.

      C99 says that a precision given as simply '.' with no following digits

      says that if both the precision and value are 0, no digits should be
      printed. Even if the kernel followed C99 to the letter, I don't think
      that would be particularly useful in these cases. For consistency with

      journal head reference and bh_state lock. Avoid that by checking whether
      any modification to the buffer is needed before grabbing any locks or
      references.

        reverted in ebeaa8ddb3663b5 due to a false positive triggering of an

      Input: wdt87xx_i2c - change the sleep time to 2500ms after the sw reset

      The original wait time was 200ms which was enough for the firmware to
      finish loading and boot. After that the firmware will perform
      initialization and touch calibration, which will take about 1.1 second. 
The
      touch calibration will change controller frequency to scan at the most
      optimal frequency and during calibration/frequency switching process we 
may
      run into i2c data errors. To avoid them we extend the sleep to 2500ms 
after
      issuing the sw reset.

      Revert "ipv4: use skb coalescing in defragmentation"

      This reverts commit 3cc4949269e01f39443d0fcfffb5bc6b47878d45.

      There is nothing wrong with coalescing during defragmentation, it
      reduces truesize overhead and simplifies things for the receiving
      socket (no fraglist walk needed).

      However, it also destroys geometry of the original fragments.
      While that doesn't cause any breakage (we make sure to not exceed largest
      original size) ip_do_fragment contains a 'fastpath' that takes advantage
      of a present frag list and results in fragments that (in most cases)
      match what was received.

      In case its needed the coalescing could be done later, when we're sure
      the skb is not forwarded.  But discussion during NFWS resulted in
      'lets just remove this for now'.

      ARM: BCM63xx: Remove custom secondary_startup function

      With commit 02b4e2756e01c623cc4dbceae4b07be75252db5b ("ARM: v7 setup
      function should invalidate L1 cache"), the default secondary_startup
      function for ARMv7 CPUs does invalidate the L1 cache, which was the sole
      reason why BCM63xx had to have its own secondary_startup implementation.

      Now that the secondary_startup takes care of this, we can completely
      remove that code.

bcm63138_smp_boot_secondary

      of_get_cpu_node provides the device node associated with the given
      logical CPU and cpu_logical_map contains the physical id for each CPU
      in the logical ordering. Passing cpu_logical_map(cpu) to of_get_cpu_node
      is incorrect.

      This patch fixes the issue by passing the logical CPU number to
      of_get_cpu_node

      Chained irq handlers usually set up handler data as well. We now have
      a function to set both under irq_desc->lock. Replace the two calls
      with one.

      irqchip: Prepare for local stub header removal

      The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
      the local irqchip.h became an empty shell, which solely includes
      include/linux/irqchip.h

      Include the global header in all irqchip drivers instead of the local
      header, so we can remove it.

      irqchip/sirfsoc: Fix generic chip allocation wreckage

      irq_alloc_domain_generic_chips() can only be called once for an
      irqdomain. The sirfsoc init calls it twice and because the return
      value is not checked it does not notice the wreckage.

      The code works by chance because the first call already allocates two
      chips and therefor the second call to sirfsoc_alloc_gc() operates on
      the proper generic chip instance.

      Use a single call and setup the two chips in the obvious correct way.

      irqchip/dw-apb-ictl: Fix generic domain chip wreckage

      The num_ct argument of irq_alloc_domain_generic_chips() tells the core
      code how many chip types (for different control flows,
      e.g. edge/level) should be allocated. It does not control how many
      generic chip instances are created because that's determined from the
      irq domain size and the number of interrupts per chip.

      The dw-apb init abuses the num_ct argument for allocating one or two
      chip types depending on the number of interrupts. That's completely
      wrong because the alternate type is never used.

      This code was obviously never tested on a system which has more than
      32 interrupts as that would have never worked due to the unitialized
      second generic chip instance.

      Hand in the proper num_ct=1 and fixup the chip initialization along
      with the interrupt handler.

      ath9k: DFS - add pulse chirp detection for FCC

      FCC long pulse radar (type 5) requires pulses to be
      checked for chirping. This patch implements chirp
      detection based on the FFT data provided for long
      pulses.

      A chirp is detected when a set of criteria defined
      by FCC pulse characteristics is met, including
      * have at least 4 FFT samples
      * max_bin index moves equidistantly between samples
      * the gradient is within defined range

      The chirp detection has been tested with reference
      radar generating devices and proved to work reliably.

      ====================
      be2net: patch set

      Hi David, the following patch set has code cleanup patches, minor 
enhancements
      and non-critical fixes. Pls consider applying to the net-next tree. 
Thanks!

      Patch 1 removes duplicate code in be_setup_wol() routine making it simpler
      and more readable.

      Patch 2 fixes the the bridge mode return value for the 
ndo_bridge_getlink()
      call. Instead of just relying on the SRIOV enabled state, the driver now
      queries the FW, for the actual mode of bridge.

      Patch 3 removes code for setting D0 power state as it's already done
      in pci_enable_device()

      Patch 4 fixes a bad return value in be_check_ufi_compatibility() routine
      introduced by an earlier commit.

      Patch 5 fixes a field in udp header being accessed while in network endian
      format.

      Patch 6 fixes the be_mcc_notify() routine to return an error status when
      the FW/HW is in an error state.

      Patch 7 fixes the be_cmd_rx_filter() routine to issue the RX_FILTER cmd
      and not wait for a completion from the FW. If the FW/adapter
      is in an error state, this change helps in not holding up the rtnl_lock
      and keeping bottom halves disabled while the driver timesout waiting for
      a response from the FW.

      Patch 8 fixes the be_cmd_set_loopback() routine to issue the LOOPBACK cmd
      and not wait for the FW completion while spin_lock_bh() is held on the
      mcc_lock. As the cmd is always issued from ethtool in a process context,
      it can sleep till the FW completion is received.

      Patch 9 bumps up the driver version to 10.6.0.3

      be2net: make SET_LOOPBACK_MODE cmd asynchrounous

      The SET_LOOPBACK_MODE command is always issued from ethtool only in a
      process context. So, while waiting for the cmd to complete, the driver
      can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
      by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
      only after the cmd completes while the MCCQ is locked).

      be2net: make the RX_FILTER command asynchronous

      This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues
      this cmd and doesn't wait for a completion from the FW. If the FW/adapter
      is in an error state, this change helps in not holding up the rtnl_lock
      and keeping bottom halves disabled while the driver timesout waiting for
      a response from the FW.

      be2net: query FW to check if EVB is enabled

      The current code assumes that bridge functionality (EVB) in the adapter
      is enabled only when SR-IOV is enabled. This is not always true.
      This patch uses the GET_HSW_CONFIG FW cmd to query this from the FW.

      DocBook: Avoid building man pages repeatedly and inconsistently

      Some kernel-doc sections are included in multiple DocBook files.  This
      means the mandocs target will generate the same manual page multiple
      times with different metadata (author name/address and manual title,
      taken from the including DocBook file).  If it's invoked in a parallel
      build, the output is nondeterminstic.

      For each section that is duplicated, mark the less specific manual's
      inclusion as 'extra' and exclude it during conversion to manual pages.
      Use xmlif for this, as that is bundled with xmlto which we already
      use.

      I would have preferred to use more conventional markup for this, but
      each of the following approaches failed:

      1. Wrap the extra inclusions with a new element and add a template to
         the stylesheet to include/exclude them.  Unfortunately DocBook XSL
         doesn't seem to support foreign elements at an intermediate level
         in the document tree.
      2. Use DocBook profiling.  This works but requires passing an absolute
         path to the profile stylesheet to xmlto, so it's not portable.
      3. Use SGML marked sections.  docbook2x can handle these but xmlto
         chokes on them.

      compressed man pages unreproducible.  Neither of these are important

      scripts/kernel-doc: parse kernel-doc deterministically

      Regular expressions for highlights in kernel-doc are stored in a Perl
      hash.  These hashes are ordered differently for each Perl run. This will
      prevent kernel-doc to behave deterministically when parsing â??@foo()â?? 
as
      in some runs it will be interpreted as a parameter and in the others it

      mnt: fs_fully_visible enforce noexec and nosuid  if !SB_I_NOEXEC

      The filesystems proc and sysfs do not have executable files do not
      have exectuable files today and portions of userspace break if we do
      enforce nosuid and noexec consistency of nosuid and noexec flags
      between previous mounts and new mounts of proc and sysfs.

      Add the code to enforce consistency of the nosuid and noexec flags,
      and use the presence of SB_I_NOEXEC to signal that there is no need to
      bother.

      This results in a completely userspace invisible change that makes it
      clear fs_fully_visible can only skip the enforcement of noexec and
      nosuid because it is known the filesystems in question do not support
      executables.

      vfs: Commit to never having exectuables on proc and sysfs.

      Today proc and sysfs do not contain any executable files.  Several
      applications today mount proc or sysfs without noexec and nosuid and
      then depend on there being no exectuables files on proc or sysfs.
      Having any executable files show on proc or sysfs would cause
      a user space visible regression, and most likely security problems.

      Therefore commit to never allowing executables on proc and sysfs by
      adding a new flag to mark them as filesystems without executables and
      enforce that flag.

      Test the flag where MNT_NOEXEC is tested today, so that the only user
      visible effect will be that exectuables will be treated as if the
      execute bit is cleared.

      The filesystems proc and sysfs do not currently incoporate any
      executable files so this does not result in any user visible effects.

      This makes it unnecessary to vet changes to proc and sysfs tightly for
      adding exectuable files or changes to chattr that would modify
      existing files, as no matter what the individual file say they will
      not be treated as exectuable files by the vfs.

      Not having to vet changes to closely is important as without this we
      are only one proc_create call (or another goof up in the
      implementation of notify_change) from having problematic executables
      on proc.  Those mistakes are all too easy to make and would create
      a situation where there are security issues or the assumptions of
      some program having to be broken (and cause userspace regressions).

      ARM: 8395/1: l2c: Add support for the "arm,shared-override" property

      "CoreLink Level 2 Cache Controller L2C-310", p. 2-15, section 2.3.2
      Shareable attribute" states:

          "The default behavior of the cache controller with respect to the
           shareable attribute is to transform Normal Memory Non-cacheable
           transactions into:
              - cacheable no allocate for reads
              - write through no write allocate for writes."

      Depending on the system architecture, this may cause memory corruption
      in the presence of bus mastering devices (e.g. OHCI). To avoid such
      corruption, the default behavior can be disabled by setting the Shared
      Override bit in the Auxiliary Control register.

      Currently the Shared Override bit can be set only using C code:
        - by calling l2x0_init() directly, which is deprecated,
        - by setting/clearing the bit in the machine_desc.l2c_aux_val/mask
          fields, but using values differing from 0/~0 is also deprecated.

      Hence add support for an "arm,shared-override" device tree property for
      the l2c device node. By specifying this property, affected systems can
      indicate that non-cacheable transactions must not be transformed.
      Then, it's up to the OS to decide. The current behavior is to set the
      "shared attribute override enable" bit, as there may exist kernel linear
      mappings and cacheable aliases for the DMA buffers, even if CMA is
      enabled.

      See also commit 1a8e41cd672f894b ("ARM: 6395/1: VExpress: Set bit 22 in
      the PL310 (cache controller) AuxCtlr register"):

          "Clearing bit 22 in the PL310 Auxiliary Control register (shared
           attribute override enable) has the side effect of transforming
           Normal Shared Non-cacheable reads into Cacheable no-allocate reads.

           Coherent DMA buffers in Linux always have a Cacheable alias via the
           kernel linear mapping and the processor can speculatively load
           cache lines into the PL310 controller. With bit 22 cleared,
           Non-cacheable reads would unexpectedly hit such cache lines leading
           to buffer corruption."

      HID: cp2112: support i2c write-read transfers in hid-cp2112

      cp2112_i2c_xfer() only supports a single i2c_msg.  More than
      one message at a time just returns EIO.  This breaks certain
      important cases.  For example, the at24 eeprom driver generates
      paired write and read messages (for eeprom address and data).

      Since the device doesn't support i2c repeated starts in general,
      but does support a single write-repeated-start-read pair
      (since hardware rev 1), we recognize the latter case and
      implement only that.

      inet_twsk_deschedule() calls are followed by inet_twsk_put().

      Only particular case is in inet_twsk_purge() but there is no point
      to defer the inet_twsk_put() after re-enabling BH.

      Lets rename inet_twsk_deschedule() to inet_twsk_deschedule_put()
      and move the inet_twsk_put() inside.

      inet: simplify timewait refcounting

      timewait sockets have a complex refcounting logic.
      Once we realize it should be similar to established and
      syn_recv sockets, we can use sk_nulls_del_node_init_rcu()
      and remove inet_twsk_unhash()

      In particular, deferred inet_twsk_put() added in commit
      13475a30b66cd ("tcp: connect() race with timewait reuse")
      looks unecessary : When removing a timewait socket from
      ehash or bhash, caller must own a reference on the socket
      anyway.

      tcp: fixes some congestion control corner cases

      This patch series fixes corner cases of TCP congestion control.
      First issue is to avoid continuing slow start when cwnd reaches ssthresh.
      Second issue is incorrectly processing order of congestion state and
      cwnd update when entering fast recovery or undoing cwnd.

      tcp: update congestion state first before raising cwnd

      The congestion state and cwnd can be updated in the wrong order.
      For example, upon receiving a dubious ACK, we incorrectly raise
      the cwnd first (tcp_may_raise_cwnd()/tcp_cong_avoid()) because
      the state is still Open, then enter recovery state to reduce cwnd.

      For another example, if the ACK indicates spurious timeout or
      retransmits, we first revert the cwnd reduction and congestion
      state back to Open state.  But we don't raise the cwnd even though
      the ACK does not indicate any congestion.

      To fix this problem we should first call tcp_fastretrans_alert() to
      process the dubious ACK and update the congestion state, then call
      tcp_may_raise_cwnd() that raises cwnd based on the current state.

      tcp: do not slow start when cwnd equals ssthresh

      In the original design slow start is only used to raise cwnd
      when cwnd is stricly below ssthresh. It makes little sense
      to slow start when cwnd == ssthresh: especially
      when hystart has set ssthresh in the initial ramp, or after
      recovery when cwnd resets to ssthresh. Not doing so will
      also help reduce the buffer bloat slightly.

      tcp: v1 always send a quick ack when quickacks are enabled

      V1 of this patch contains Eric Dumazet's suggestion to move the per
      dst RTAX_QUICKACK check into tcp_in_quickack_mode(). Thanks Eric.

      I ran some tests and after setting the "ip route change quickack 1"
      knob there were still many delayed ACKs sent. This occured
      because when icsk_ack.quick=0 the !icsk_ack.pingpong value is
      subsequently ignored as tcp_in_quickack_mode() checks both these
      values. The condition for a quick ack to trigger requires
      that both icsk_ack.quick != 0 and icsk_ack.pingpong=0. Currently
      only icsk_ack.pingpong is controlled by the knob. But the
      icsk_ack.quick value changes dynamically depending on heuristics.
      The crux of the matter is that delayed acks still cannot be entirely
      disabled even with the RTAX_QUICKACK per dst knob enabled. This
      patch ensures that a quick ack is always sent when the RTAX_QUICKACK
      per dst knob is turned on.

      The "ip route change quickack 1" knob was recently added to enable
      quickacks. It was modeled around the TCP_QUICKACK setsockopt() option.
      This issue is that even with "ip route change quickack 1" enabled
      we still see delayed ACKs under some conditions. It would be nice
      to be able to completely disable delayed ACKs.

      Here is an example:

      # netstat -s|grep dela
          3 delayed acks sent

      For all routes enable the knob

      # ip route change quickack 1

      Generate some traffic across a slow link and we still see the delayed
      acks.

      # netstat -s|grep dela
          106 delayed acks sent
          1 delayed acks further delayed because of locked socket

      The issue is that both the "ip route change quickack 1" knob and
      the TCP_QUICKACK option set the icsk_ack.pingpong variable to 0.
      However at the business end in the __tcp_ack_snd_check() routine,
      tcp_in_quickack_mode() checks that both icsk_ack.quick != 0
      and icsk_ack.pingpong=0 in order to trigger a quickack. As
      icsk_ack.quick is determined by heuristics it can be 0. When
      that occurs the icsk_ack.pingpong value is ignored and a delayed
      ACK is sent regardless.

      This patch moves the RTAX_QUICKACK per dst check into the
      tcp_in_quickack_mode() routine which ensures that a quickack is
      always sent when the quickack knob is enabled for that dst.

      drm/i915: fbdev restore mode needs to invalidate frontbuffer

      This fbdev restore mode was another corner case that was now
      calling frontbuffer flip and flush and making we miss
      screen updates with PSR enabled.

          when possible and put brackets on if.

      drm/i915: fbdev_set_par reliably invalidating frontbuffer

      fbdev_set_par is called when fbcon is taking over control.
      In the past frontbuffer was being invalidated on
      set_to_gtt_domain, but it moved to set_domain fixing that case,
      but left this behind and broken in

          drm/i915: Unconditionally do fb tracking invalidate in set_domain

      Note that even before this commit it wasn't perfect since the
      invalidate was omitted if the fbcon was already in the GTT domain,
      which it usually was.

      Since we are also invalidating in other fbdev cases this one
      was masked here. At least until now that I found this corner
      case: On boot with plymouth doing a splash screen
      when returning to the console frontbuffer wans't being invalidated
      causing missed screen updates with PSR enabled.

      So this patch fixes this issue.

      v2: Make invalidate directly and unconditionally and
          fix commit message indicating the set_domain fix
          as pointed out by Daniel.
      v3: Remove unecessary if(obj) added by mistake

      There are some panels that requires up to minimum of 4 idle

      Let's trust VBT when it is set + 1  and use minimum of 4 + 1

      drm/i915: PSR: Remove Low Power HW tracking mask.

      By Spec we should only mask memup and hotplug detection
      for hardware tracking cases. However we always masked
      LPSP because with power well always enabled on audio
      PSR was never being activated and residency was always
      zeroed.

      Apparently audio driver is tying power well management
      and runtime PM for some reason. But with audio runtime
      PM working or with audio completely out of picture
      we should remove this mask, otherwise we have a high
      risk of miss screen updates as faced by Matthew.

      WARNING: With this patch if snd_intel_hda driver is
      running and not releasing power well properly PSR will
      constant Exit and Performance Counter will be 0.

      But the best thing of this patch is that with one more
      HW tracking working the risks of missed blank screen
      are minimized at most.

      This affects just core platforms where PSR exit are also
      helped by HW tracking: Haswell, Broadwell and Skylake
      for now.

      v2: Fix commit message explanation. It has nothing to do
      with runtime PM on i915 as previously advertised.

      drm/i915: dirty fb operation flushsing frontbuffer

      Let's do a frontbuffer flush on dirty fb.
      To be used for DIRTYFB drm ioctl.

      This patch solves the biggest PSR known issue, that is
      missed screen updates during boot, mainly when there is a splash
      screen involved like Plymouth.

      Previously PSR was being invalidated by fbdev and Plymounth
      was taking control with PSR yet invalidated and could get screen
      updates normally. However with some atomic modeset changes
      Pymouth modeset over ioctl was now causing frontbuffer flushes
      making PSR gets back to work while it cannot track the
      screen updates and exit properly.

      By adding this flush on dirtyfb we properly track frontbuffer
      writes and properly exit PSR.

      Actually all mmap_wc users should call this dirty callback
      in order to have a proper frontbuffer tracking.

      In the future it can be extended to return 0 if the whole
      screen has being flushed or the number of rects flushed
      as Chris suggested.

      v2: Remove ORIGIN_FB_DIRTY and use ORIGIN_GTT instead since dirty
          callback is just called after few screen updates and not on
          everyone as pointed by Daniel.

      v3: Use flush instead of invalidate since flush means
          invalidate + flush and dirty means drawn had finished and
          it can be flushed.

      v4: Remove PSR from subject since it is purely frontbuffer tracking
          change and that can be useful for FBC as well.

      drm/i915: PSR: Flush means invalidate + flush

      Since flush actually means invalidate + flush we need to force psr
      exit on PSR flush.

      On Core platforms there is no way to disable hw tracking and
      do the pure sw tracking so we simulate it by fully disable psr and
      reschedule a enable back.
      So a good idea is to minimize sequential disable/enable in cases we
      know that HW tracking like when flush has been originated by a flip.
      Also flip had just invalidated it already.

      It also uses origin to minimize the a bit the amount of
      disable/enabled, mainly when flip already had invalidated.

      With this patch in place it is possible to do a flush on dirty areas
      properly in a following patch.

      v2: Remove duplicated exit on HSW+Sprites as pointed out by Paulo.

      The Armada 388 GP board has the following hardware features that were
      not enabled in mvebu_v7_defconfig:

       * An AT24 I2C EEPROM (also used by armada-xp-lenovo-ix4-300d)
       * A PCA9555 I2C GPIO expander
       * Several fixed regulators

      Therefore, this commit adds the necessary options to mvebu_v7_defconfig.

      power_supply: rt9455_charger: Properly notify userspace about charging 
events

      Charging events this patch refers to are:
      - charger is connected to/disconnected from the power source
      - battery is reconnected to the charger, after it was absent.

      When the charger is connected to/disconnected from the power source, 
CHRVPI
      interrupt occurs and PWR_RDY bit is either set or cleared. PWR_RDY bit is
      updated after 1-2 seconds CHRVPI interrupt has occurred.
      power_supply_changed() should be called after PWR_RDY bit is updated.
      /sys/class/power_supply/rt9455-charger/online file displays the value of
      PWR_RDY bit.
      This way, if the userspace is notified that a charging event has occurred
      and the userspace reads /sys/class/power_supply/rt9455-charger/online 
file,
      this file is properly updated when the userspace reads it.
      This is the reason why power_supply_changed() is called in
      rt9455_pwr_rdy_work_callback(), instead of being called in interrupt
      handler.

      Since no interrupt is triggered when the battery is reconnected to the
      charger, the userspace is never notified that the battery is reconnected.
      This is why power_supply_changed() is called in
      rt9455_max_charging_time_work_callback(), so that the userspace is 
notified
      that the battery is reconnected.

      hv_netvsc: Add support to set MTU reservation from guest side

      When packet encapsulation is in use, the MTU needs to be reduced for
      headroom reservation.
      The existing code takes the updated MTU value only from the host side.
      But vSwitch extensions, such as Open vSwitch, require the flexibility
      to change the MTU to different values from within a guest during the
      lifecycle of a vNIC, when the encapsulation protocol is changed. The
      patch supports this kind of MTU changes.

      Like act_gact, act_mirred can be lockless in packet processing

      1) Use percpu stats
      2) update lastuse only every clock tick to avoid false sharing
      3) use rcu to protect tcfm_dev
      4) Remove spinlock usage, as it is no longer needed.

      Next step : add multi queue capability to ifb device

      net_sched: act_gact: remove spinlock in fast path

      Final step for gact RCU operation :

      1) Use percpu stats
      2) update lastuse only every clock tick to avoid false sharing
      3) Remove spinlock acquisition, as it is no longer needed.

      Since this is the last contended lock in packet RX when tc gact is used,
      this gives impressive gain.

      My host with 8 RX queues was handling 5 Mpps before the patch,
      and more than 11 Mpps after patch.

      Tested:

      On receiver :

      dev=eth0
      tc qdisc del dev $dev ingress 2>/dev/null
      tc qdisc add dev $dev ingress
      tc filter del dev $dev root pref 10 2>/dev/null
      tc filter del dev $dev pref 10 2>/dev/null
      tc filter add dev $dev est 1sec 4sec parent ffff: protocol ip prio 1 \
        u32 match ip src 7.0.0.0/8 flowid 1:15 action drop

      Sender sends packets flood from 7/8 network

      tcp: reducing lost retransmits in recovery

      This patch series reduces lost retransmits in recovery, in particular
      when dealing with traffic policers. The main problem is that
      slow start in recovery under policing can cause massive lost and
      retransmit storms: any excess sending rate turns into drops. The
      solution is to avoid doing slow start when lost retransmit is
      detected and use packet conservation instead.

      On networks with traffic policers the patches have lowered the
      TCP loss rates by ~20% from Google servers without latency regressions.

      tcp: PRR uses CRB mode by default and SS mode conditionally

      PRR slow start is often too aggressive especially when drops are
      caused by traffic policers. The policers mainly use token bucket
      to enforce the rate so sending (twice) faster than the delivery
      rate causes excessive drops.

      This patch changes PRR to the conservative reduction bound
      (CRB) mode in RFC 6937 by default. CRB follows the packet
      conservation rule to send at most the delivery rate by default.

      But if many packets are lost and the pipe is empty, CRB may take N
      round trips to repair N losses. We conditionally turn on slow start
      mode if all these conditions are made to speed up the recovery:

        1) on the second round or later in recovery
        2) retransmission sent in the previous round is delivered on this ACK
        3) no retransmission is marked lost on this ACK

      By using packet conservation by default, this change reduces the loss
      retransmits signicantly on networks that deploy traffic policers,
      up to 20% reduction of overall loss rate.

      tcp: reduce cwnd if retransmit is lost in CA_Loss

      If the retransmission in CA_Loss is lost again, we should not
      continue to slow start or raise cwnd in congestion avoidance mode.
      Instead we should enter fast recovery and use PRR to reduce cwnd,
      following the principle in RFC5681:

      "... or the loss of a retransmission, should be taken as two
       indications of congestion and, therefore, cwnd (and ssthresh) MUST
       be lowered twice in this case."

      This is especially important to reduce loss when the CA_Loss
      state was caused by a traffic policer dropping the entire inflight.
      The CA_Loss state has a problem where a loss of L packets causes the
      sender to send a burst of L packets. So a policer that's dropping
      most packets in a given RTT can cause a huge retransmit storm. By
      contrast, PRR includes logic to bound the number of outbound packets
      that result from a given ACK. So switching to CA_Recovery on lost
      retransmits in CA_Loss avoids this retransmit storm problem when
      in CA_Loss.

      As the undefined behavior might only manifest itself later on it is not

      drm/i915: Update wa_ctx_emit() macro as per kernel coding guidelines

      wa_ctx_emit() depends on the name of a local variable; if the name of that
      variable is changed then we get compile errors. In this case it is 
unlikely
      to be changed as this macro is only used in this set of functions but
      Kernel coding guidelines doesn't recommend doing this. It was my mistake
      as I should have corrected it at the beginning but missed so correct
      this before there are more usages of this macro (Bob Beckett).

      "
      2) macros that depend on having a local variable with a magic name:

         #define FOO(val) bar(index, val)

      might look like a good thing, but it's confusing as hell when one reads 
the
      code and it's prone to breakage from seemingly innocent changes.
      "

      v2: Optimization to avoid multiple evaluation of 'index' in the macro.
      Since we invoke it multiple times, compiler, if it can, should be able to 
coalesce
      them into a single condition and remove multiple WARN_ON checks (Chris).

      HID: i2c-hid: Call device suspend callback before disabling irq

      i2c-hid takes care of requesting and handling IRQs for HID devices
      which in turns might expect them to be always active when working
      in normal conditions. Hence, disabling IRQs before calling the suspend
      callbacks can potentially cause problems since device drivers might
      try to perform operations needing them.

      Fix this by disabling IRQs only after the suspend callbacks had been
      executed.

      Because the cool kids use dev_priv and FBC wants to be cool too.

      We've been historically using struct drm_device on the FBC function
      arguments, but we only really need it for intel_vgpu_active(): we can
      use dev_priv everywhere else. So let's fully switch to dev_priv since
      I'm getting tired of adding "struct drm_device *dev = dev_priv->dev"
      everywhere.

      If I get a NACK here I'll propose the opposite: convert all the
      functions that currently take dev_priv to take dev.

      crypto: omap-aes - Fix configuring of AES mode

      AES_CTRL_REG is used to configure AES mode. Before configuring
      any mode we need to make sure all other modes are reset or else
      driver will misbehave. So mask all modes before configuring
      any AES mode.

      regulator: pwm-regulator: Don't assign structure attributes right away

      Perhaps this is just personal preference, but ...

      This patch introduces a new local variable to receive and test regulator
      initialisation data.  It simplifies and cleans up the code making it
      that little bit easier to read and maintain.  The local value is assigned
      to the structure attribute when all the others are.  This is the way we
      usually do things.

      Prevents this kind of nonsense:

        this->is->just.silly = fetch_silly_value(&pointer);
        if (!this->is->just.silly) {
                printk("Silly value failed: %d\n", this->is->just.silly);

      regulator: pwm-regulator: Simplify voltage to duty-cycle call

      If we reverse some of the logic and change the formula used,
      we can simplify the function greatly.

      It is intentional that this function is supplied and then re-worked
      within the same patch-set.  The submission in the previous patch is
      the tried and tested (i.e. in real releases) method written by ST.
      This patch contains a simplification provided later.  It looks and
      performs better, but doesn't have the same time-under-test that the
      original method does.  The idea is that we keep some history in
      order to provide an easy way back i.e. revert.

      regulator: pwm-regulator: Add support for continuous-voltage

      The current version of PWM regulator only supports a static table
      approach, where pre-calculated values are supplied by the vendor and
      obtained via DT.  The continuous-voltage method takes min_uV and
      max_uV, and divides the difference between them up into a number of
      slices.  The number of slices depend on how large the duty cycle
      register is.  This information is provided by a DT property.

      As the name alludes, this provides values for a continuous voltage
      range between min_uV and max_uV, which has obvious benefits over
      either limited voltage possibilities, or the requirement to provide
      a large voltage-table.

      ASoC: dpcm: Add checks of playback/capture before dpcm_get_be

      In dpcm_get_be(), it looks for a BE rtd that has the DAI widget
      according to current stream type. Only playback_widgets are searched
      in the case of playback stream and vice versa. However, the DAI widget
      itself can be playback or capture.

      If the DAI widget is capture, but current stream type is playback,
      dpcm_get_be() will always fail to find a rtd, print error messages,
      and continue to the next DAI widget in list. We can just skip this
      DAI widget to further suppress error messages. This happens in a
      special case when 2 codecs are inter-connected, and the 1st codec's
      "capture" widget is used to send data to the 2nd codec during "playback":

      mtk-rt5650-rt5676 sound: ASoC: can't get playback BE for Sub AIF2 Capture
      rt5650_rt5676 Playback: ASoC: no BE found for Sub AIF2 Capture

      Add checks to continue to next DAI widget if current DAI widget's
      direction does not match the stream type.

      While we never would successfully load on the wrong machine type, there
      is extra output by default regardless of machine type.

      For instance, on a PowerVM LPAR, we see the following:

      even though those coprocessors could never be found.

      The AEAD version of cryptd uses the same context for its own state

      Add support to configure Enhanced Transient Response Enable (ETR)
      and Sensitivity Selection based on maximum current i.e. expected
      load on that rail.

      Maxim recommended as:
      - Enable ETR with high sensitivity (75mV/us) for 0 to 9A expected loads,
      - Enable ETR with low sensitivity (150mV/us) for 9A to 12A expected loads.
      - Disable ETR for expected load > 12A.

      These recommendation will be configured for MAX77621 when maximum load
      is provided through regulator constraint for maximum current from 
platform.

      regulator: max8973: add support to configure ETR from DT

      The MAX8973/MAX77621 feature an Enhanced Transient Response(ETR)
      circuit that is enabled through software. The enhanced transient
      response reduces the voltage droop during large load steps by
      temporarily allowing all three phases to fire in unison, slewing
      total inductor current faster than would normally be possible if
      all three phases continued to operate 120deg out of phase. The
      enhanced transient response detector features two selectable
      sensitivity settings, which select the output voltage slew rate
      during load transients that triggers the ETR circuit. The sensitivity
      of the ETR detector is set by the CKADV[1:0] bits in the CONTROL2
      register.

      Add support to configure the ETR through platform data from DT.
      Update the DT binding document accordingly.

      Memory for this struct is allocated by spi_alloc_master() using
      kzalloc() so it doesn't need to be set to 0 one more time.

      spi: Fix per-page mapping of unaligned vmalloc-ed buffer

      spi_map_buf() processes mapping of vmalloc-ed buffers in a special way,
      making mapping of every page separately. However, if the buffer is not
      aligned to page boundary (e.g. sub-array in a vmalloc-ed array), it
      fills the scatter table with page-size unaligned pieces, that cross
      page boundaries. This is incorrect and can, for example, cause memory
      corruption and various crashes when working with ubifs on spi-nor chips
      (though those drivers are themselves buggy in that they should be
      providing DMAable memory to the SPI framework).

      Fix this by using proper scatter table size and intra-page buffer lengths,
      so that the whole buffer splits into separate scatter table entries on
      page boundaries.

      spi: img-spfi: check for max speed supported by the spfi block

      Maximum speed supported by spfi is limited to 1/4 of the spfi clock.

      But in some SoCs the maximum speed supported by the spfi block can
      be limited to less than 1/4 of the spfi clock. In such cases we have
      to define the limit in the device tree so that the driver can pick
      it up.

      This patch moves the requesting supplies, hardware reset and

      So that the codec hardware is initialized when loading the codec driver,

      resets and re-initializations when re-loading the machine driver.

      x86/entry: Remove exception_enter() from most trap handlers

      On 64-bit kernels, we don't need it any more: we handle context
      tracking directly on entry from user mode and exit to user mode.

      On 32-bit kernels, we don't support context tracking at all, so
      these callbacks had no effect.

      Note: this doesn't change do_page_fault().  Before we do that,
      we need to make sure that there is no code that can page fault
      from kernel mode with CONTEXT_USER.  The 32-bit fast system call
      stack argument code is the only offender I'm aware of right now.

      x86/entry: Add new, comprehensible entry and exit handlers written in C

      The current x86 entry and exit code, written in a mixture of assembly and
      C code, is incomprehensible due to being open-coded in a lot of places
      without coherent documentation.

      It appears to work primary by luck and duct tape: i.e. obvious runtime
      failures were fixed on-demand, without re-thinking the design.

      Due to those reasons our confidence level in that code is low, and it is
      very difficult to incrementally improve.

      Add new code written in C, in preparation for simply deleting the old
      entry code.

      prepare_exit_to_usermode() is a new function that will handle all
      slow path exits to user mode.  It is called with IRQs disabled
      and it leaves us in a state in which it is safe to immediately
      return to user mode.  IRQs must not be re-enabled at any point
      after prepare_exit_to_usermode() returns and user mode is actually
      entered. (We can, of course, fail to enter user mode and treat
      that failure as a fresh entry to kernel mode.)

      All callers of do_notify_resume() will be migrated to call
      prepare_exit_to_usermode() instead; prepare_exit_to_usermode() needs
      to do everything that do_notify_resume() does today, but it also
      takes care of scheduling and context tracking.  Unlike
      do_notify_resume(), it does not need to be called in a loop.

      syscall_return_slowpath() is exactly what it sounds like: it will
      be called on any syscall exit slow path. It will replace
      syscall_trace_leave() and it calls prepare_exit_to_usermode() on the
      way out.

      x86/entry: Add enter_from_user_mode() and use it in syscalls

      Changing the x86 context tracking hooks is dangerous because
      there are no good checks that we track our context correctly.
      Add a helper to check that we're actually in CONTEXT_USER when
      we enter from user mode and wire it up for syscall entries.

      Subsequent patches will wire this up for all non-NMI entries as
      well.  NMIs are their own special beast and cannot currently
      switch overall context tracking state.  Instead, they have their
      own special RCU hooks.

      This is a tiny speedup if !CONFIG_CONTEXT_TRACKING (removes a
      branch) and a tiny slowdown if CONFIG_CONTEXT_TRACING (adds a
      layer of indirection).  Eventually, we should fix up the core
      context tracking code to supply a function that does what we
      want (and can be much simpler than user_exit), which will enable
      us to get rid of the extra call.

      x86/traps, context_tracking: Assert that we're in CONTEXT_KERNEL in 
exception entries

      Other than the super-atomic exception entries, all exception
      entries are supposed to switch our context tracking state to
      CONTEXT_KERNEL. Assert that they do.  These assertions appear
      trivial at this point, as exception_enter() is the function
      responsible for switching context, but I'm planning on reworking
      x86's exception context tracking, and these assertions will help
      make sure that all of this code keeps working.

      x86/entry: Move C entry and exit code to arch/x86/entry/common.c

      The entry and exit C helpers were confusingly scattered between
      ptrace.c and signal.c, even though they aren't specific to
      ptrace or signal handling.  Move them together in a new file.

      This change just moves code around.  It doesn't change anything.

      um: Fix do_signal() prototype

      Once x86 exports its do_signal(), the prototypes will clash.

      Fix the clash and also improve the code a bit: remove the
      unnecessary kern_do_signal() indirection. This allows
      interrupt_end() to share the 'regs' parameter calculation.

      Also remove the unused return code to match x86.

      Minimally build and boot tested.

      x86/entry/64/compat: Fix bad fast syscall arg failure path

      If user code does SYSCALL32 or SYSENTER without a valid stack,
      then our attempt to determine the syscall args will result in a
      failed uaccess fault.  Previously, we would try to recover by
      jumping to the syscall exit code, but we'd run the syscall exit
      work even though we never made it to the syscall entry work.

      Clean it up by treating the failure path as a non-syscall entry
      and exit pair.

      This fixes strace's output when running the syscall_arg_fault
      test. Without this fix, strace would get out of sync and would
      fail to associate syscall entries with syscall exits.

      x86/entry, selftests/x86: Add a test for 32-bit fast syscall arg faults

      This test passes on 4.0 and fails on some newer kernels.
      Fortunately, the failure is likely not a big deal.

      This test will make sure that we don't break it further (e.g. OOPSing)
      as we clean up the entry code and that we eventually fix the
      regression.

      There's arguably no need to preserve the old ABI here --
      anything that makes it into a fast (vDSO) syscall with a bad
      stack is about to crash no matter what we do.

      out of a preferred node to a less preferred node. The reason for this
      being:

       - Since sched features NUMA and NUMA_RESIST_LOWER are disabled by
         default, migrate_degrades_locality() always returns false.

       - Even if NUMA_RESIST_LOWER were to be enabled, if its cache hot,
         migrate_degrades_locality() never gets called.

      The above behaviour can mean that tasks can move out of their
      preferred node but they may be eventually be brought back to their
      preferred node by numa balancer (due to higher numa faults).

      To avoid the above, this commit merges migrate_degrades_locality() and
      migrate_improves_locality(). It also replaces 3 sched features NUMA,
      NUMA_FAVOUR_HIGHER and NUMA_RESIST_LOWER by a single sched feature
      NUMA.

      sched/numa: Check sched_feat(NUMA) in migrate_improves_locality()

      migrate_improves_locality checked sched_feat(NUMA_FAVOUR_HIGHER) but not
      sched_feat(NUMA), so disabling just the NUMA feature would leave it
      working off of old data.

      drm: Update plane->fb also for page_flip

      The legacy page_flip driver entry point is the only one left which
      requires drivers to update plane->fb themselves. All the other entry
      hooks will patch things up for the driver as needed since no one seems
      to reliable get this right, see e.g. drm_mode_set_config_internal or
      the plane->fb/old_fb handling in drm_mode_atomic_ioctl.

      Therefore unify things, which allows us to ditch a TODO from
      drm_atomic_helper_page_flip.

      This should also help the atomic transition in i915 since we keep a
      bit of legacy cruft only around because of this special behaviour in
      ->page_flip.

      commit 80279fb7ba5b ("cfg80211: properly send
      NL80211_ATTR_DISCONNECTED_BY_AP in disconnect") has changed the api of
      cfg80211_disconnected() and caused a build failure.
      Add the extra argument as false since it appears from the code that the
      disconnection is not locally generated.
      And incase of doubt we can use false as that is the default behaviour.

      The dwmac ethernet controller on the rk3288 supports phys connected
      via rgmii and rmii. With rgmii phys it is expected that the mac clock
      is provided externally while with rmii phys the clock can be external
      but also generated from the plls. In the later case it of course needs
      be at 50MHz, which gets set from the dwmac_rk driver.
      As most devices use a rgmii phy it never surfaced so far that the mac
      clk mux, doesn't go up one lever to the pll clock in the rmii case with
      internal clock generation, as it is missing the CLK_SET_RATE_PARENT flag,
      and thus will not set the correct frequency in most cases.

      ufs_inode_get{frag,block}(): get rid of 'phys' argument

      Just pass NULL as locked_page in case of first block in the indirect
      chain.  Old calling conventions aside, a reason for having 'phys'
      was that ufs_inode_getfrag() used to be able to do _two_ allocations
      - indirect block and extending/reallocating a tail.  We needed
      locked_page for the latter (it's a data), but we also needed to
      figure out that indirect block is metadata.  So we used to pass
      non-NULL locked_page in all cases *and* used NULL phys as
      indication of being asked to allocate an indirect.

      With tail unpacking taken into a separate function we don't need
      those convolutions anymore.

      __ufs_truncate_blocks(): avoid excessive dirtying of indirect blocks

      There's a case when an indirect block gets dirtied for no good
      reason - when there's a hole starting in the middle of area
      covered by it and spanning past its end, and truncate() is done
      precisely to the beginning of the hole.

      The block is obviously not modified at all - all removals happen
      beyond it.  However, existing code ends up dirtying it just in
      case.  It's trivial to fix and while it's not a real bug by any
      stretch of imagination, it makes the damn thing harder to follow.

      ufs: ufs_trunc_...() has exclusion with everything that might cause 
allocations

        Currently - on lock_ufs(), eventually - on per-inode mutex.
      lock_ufs() used to be mere BKL, which is much weaker, so it needed
      those rechecks.  BKL doesn't provide any exclusion once we lose CPU;
      its blind replacement, OTOH, _does_.  Making that per-filesystem was
      an atrocity, but at least we can simplify life here.  And yes, we
      certainly need to make that sucker per-inode - these days inode.c and
      truncate.c uses are needed only to protect the block pointers.

      ufs: kill lock_ufs()

      There were 3 remaining users; in two of them we took ->s_lock immediately
      after lock_ufs() and held it until just before unlock_ufs(); the third
      one (statfs) could not be called from itself or from other two (remount
      and sync_fs).  Just use ->s_lock in statfs and don't bother with lock_ufs
      at all.

      ufs: don't use lock_ufs() for block pointers tree protection

      * stores to block pointers are under per-inode seqlock (meta_lock) and
      mutex (truncate_mutex)
      * fetches of block pointers are either under truncate_mutex, or wrapped
      into seqretry loop on meta_lock
      * all changes of ->i_size are under truncate_mutex and i_mutex
      * all changes of ->i_lastfrag are under truncate_mutex

      It's similar to what ext2 is doing; the main difference is that unlike
      ext2 we can't rely upon the atomicity of stores into block pointers -
      on UFS2 they are 64bit.  So we can't cut the corner when switching
      a pointer from NULL to non-NULL as we could in ext2_splice_branch()
      and need to use meta_lock on all modifications.

      We use seqlock where ext2 uses rwlock; ext2 could probably also benefit
      from such change...

      Another non-trivial difference is that with UFS we *cannot* have reader
      grab truncate_mutex in case of race - it has to keep retrying.  That
      might be possible to change, but not until we lift tail unpacking
      several levels up in call chain.

      After that commit we do *NOT* hold fs-wide serialization on accesses
      to block pointers anymore.  Moreover, lock_ufs() can become a normal
      mutex now - it's only used on statfs, remount and sync_fs and none
      of those uses are recursive.  As the matter of fact, *now* it can be
      collapsed with ->s_lock, and be eventually replaced with saner
      per-cylinder-group spinlocks, but that's a separate story.

      drm/i915: Don't dereference NULL plane while setting up scalers

      intel_atomic_setup_scalers() dereferences 'plane' before the plane has
      been assigned.  The plane ID assignment doing this dereference is only
      needed for debugging messages later in the function, so just move the
      assignment farther down the function to a point where plane will no
      longer be NULL.

      This was introduced in:

      x86/platform/intel/pmc_atom: Add Cherrytrail PMC interface

      The patch adds CHT PMC interface. This exposes all the South IP
      device power states and S0ix states for CHT. The bit map of
      FUNC_DIS and D3_STS_0 registers for SoCs are consistent. The
      D3_STS_1 and FUNC_DIS_2 registers, however, are not aligned.
      This is fixed by splitting a common mapping on per register basis.

      (Originally based on code from Kumar P Mahesh.)

      soc: Mediatek: Add SCPSYS power domain driver

      This adds a power domain driver for the Mediatek SCPSYS unit.

      The System Control Processor System (SCPSYS) has several power
      management related tasks in the system. The tasks include thermal
      measurement, dynamic voltage frequency scaling (DVFS), interrupt
      filter and lowlevel sleep control. The System Power Manager (SPM)
      inside the SCPSYS is for the MTCMOS power domain control.

      For now this driver only adds power domain support, the more
      advanced features are not yet supported. The driver implements
      the generic PM domain device tree bindings, the first user will
      most likely be the Mediatek AFE audio driver.

      tools lib api debugfs: Check for tracefs when reporting errors

      Now that we have two mountpoints, one for debugfs and another, for
      tracefs, we end up needing to check permissions for both, so, on
      a system with default config we were always asking the user to
      check the permission of the debugfs mountpoint, even when it was
      already sufficient. Fix it.

      E.g.:

        $ trace -e nanosleep usleep 1
        Error: No permissions to read 
/sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit)
        Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

        $ sudo mount -o remount,mode=755 /sys/kernel/debug
        $ trace -e nanosleep usleep 1
        Error: No permissions to read 
/sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit)

      drm/i915: Mark elsps submitted when they are pushed to hw

      Now when we have requests this deep on call chain, we can mark
      the elsp being submitted when it actually is. Remove temp variable
      and readjust commenting to more closely fit to the code.

      v2: Avoid tmp variable and reduce number of writes (Chris)

  Author: George Spelvin <linux@xxxxxxxxxxx>
  Date:   Thu Jun 25 18:44:13 2015 +0200

      x86/asm/tsc: Save an instruction in DECLARE_ARGS users

      Before, the code to do RDTSC looked like:

        rdtsc
        shl $0x20, %rdx
        mov %eax, %eax
        or  %rdx, %rax

      The "mov %eax, %eax" is required to clear the high 32 bits of RAX.

      By declaring low and high as 64-bit variables, the code is
      simplified to:

        rdtsc
        shl $0x20,%rdx
        or  %rdx,%rax

      Yes, it's a 2-byte instruction that's not on a critical path,
      but there are principles to be upheld.

      Every user of EAX_EDX_RET has been checked. I tried to check
      users of EAX_EDX_ARGS, but there weren't any, so I deleted it to
      be safe.

      ( There's no benefit to making "high" 64 bits, but it was the
        simplest way to proceed. )

      x86/asm/tsc, x86/kvm: Drop open-coded barrier and use rdtsc_ordered() in 
kvmclock

      __pvclock_read_cycles() used to have two barriers, one of which was 
unnecessary,
      which got removed after an initial version of this patch was sent.

      But the barrier is still open-coded unnecessarily - get rid of
      that barrier and clean up the code by just using rdtsc_ordered().

      x86/asm/tsc: Use rdtsc_ordered() in read_tsc() instead of get_cycles()

      There are two logical changes here.  First, this removes a check
      for cpu_has_tsc.  That check is unnecessary, as we don't
      register the TSC as a clocksource on systems that have no TSC.

      Second, it adds a barrier, thus preventing observable
      non-monotonicity.

      I suspect that the missing barrier was never a problem in
      practice because system calls themselves were heavy enough
      barriers to prevent user code from observing time warps due to
      speculation. (Without the corresponding barrier in the vDSO,
      however, non-monotonicity is easy to detect.)

      x86/asm/tsc/sync: Use rdtsc_ordered() in check_tsc_warp() and drop extra 
barriers

      Using get_cycles was unnecessary: check_tsc_warp() is not called
      on TSC-less systems. Replace rdtsc_barrier(); get_cycles() with
      rdtsc_ordered().

      While we're at it, make the somewhat more dangerous change of
      removing barrier_before_rdtsc after RDTSC in the TSC warp check
      code. This should be okay, though -- the vDSO TSC code doesn't
      have that barrier, so, if removing the barrier from the warp
      check would cause us to detect a warp that we otherwise wouldn't
      detect, then we have a genuine bug.

      x86/asm/tsc: Add rdtsc_ordered() and use it in trivial call sites

      rdtsc_barrier(); rdtsc() is an unnecessary mouthful and requires
      more thought than should be necessary. Add an rdtsc_ordered()
      helper and replace the trivial call sites with it.

      This should not change generated code. The duplication of the
      fence asm is temporary.

      x86/asm/tsc: Replace rdtscll() with native_read_tsc()

      Now that the ->read_tsc() paravirt hook is gone, rdtscll() is
      just a wrapper around native_read_tsc(). Unwrap it.

      x86/asm/tsc, x86/paravirt: Remove read_tsc() and read_tscp() paravirt 
hooks

      We've had ->read_tsc() and ->read_tscp() paravirt hooks since
      the very beginning of paravirt, i.e.,

        d3561b7fa0fb ("[PATCH] paravirt: header and stubs for 
paravirtualisation").

      AFAICT, the only paravirt guest implementation that ever
      replaced these calls was vmware, and it's gone. Arguably even
      vmware shouldn't have hooked RDTSC -- we fully support systems
      that don't have a TSC at all, so there's no point for a paravirt
      implementation to pretend that we have a TSC but to replace it.

      I also doubt that these hooks actually worked. Calls to rdtscl()
      and rdtscll(), which respected the hooks, were used seemingly
      interchangeably with native_read_tsc(), which did not.

      Just remove them. If anyone ever needs them again, they can try
      to make a case for why they need them.

      Before, on a paravirt config:
        text            data     bss     dec     hex filename
        12618257      1816384 1093632 15528273 ecf151 vmlinux

      After:
        text            data     bss     dec     hex filename
        12617207      1816384 1093632 15527223 eced37 vmlinux

      x86/asm/tsc, kvm: Remove vget_cycles()

      The only caller was KVM's read_tsc(). The only difference
      between vget_cycles() and native_read_tsc() was that
      vget_cycles() returned zero instead of crashing on TSC-less
      systems. KVM already checks vclock_mode() before calling that
      function, so the extra check is unnecessary. Also, KVM
      (host-side) requires the TSC to exist.

      ... native_read_tsc() was moved out of line, presumably for some

      The entire rdtsc, shl, or sequence is only 11 bytes, and calls
      via rdtscl() and similar helpers were already inlined.

      It is found that i915 will not reset gpu under execlist mode when
      unload module. that will lead to some issues when unload/load module
      with different submission mode. e.g. from execlist mode to ring
      buffer mode via loading/unloading i915. Because HW is not in a reset
      state and registers are not clean under such condition.

      drm/i915: Update WaFlushCoherentL3CacheLinesAtContextSwitch

      In this WA we need to set GEN8_L3SQCREG4[21:21] and reset it after 
PIPE_CONTROL
      instruction but there is a slight complication as this is applied in WA 
batch
      where the values are only initialized once.
      Dave identified an issue with the current implementation where the 
register value
      is read once at the beginning and it is reused; this patch corrects this 
by saving
      the register value to memory, update register with the bit of our 
interest and
      restore it back with original value.

      This implementation uses MI_LOAD_REGISTER_MEM which is currently only used
      by command parser and was using a default length of 0. This is now updated
      with correct length and moved to appropriate place.

          size checks, we're not reallocating the CFB anymore with FBC
          enabled, so we can just move all the locking to i915_gem_stolen.c

          freeing/rellocating the CFB. This allows us to fix the "Too

      locking/qrwlock: Better optimization for interrupt context readers

      The qrwlock is fair in the process context, but becoming unfair when
      in the interrupt context to support use cases like the tasklist_lock.

      The current code isn't that well-documented on what happens when
      in the interrupt context. The rspin_until_writer_unlock() will only
      spin if the writer has gotten the lock. If the writer is still in the
      waiting state, the increment in the reader count will cause the writer
      to remain in the waiting state and the new interrupt context reader
      will get the lock and return immediately. The current code, however,
      does an additional read of the lock value which is not necessary as
      the information has already been there in the fast path. This may
      sometime cause an additional cacheline transfer when the lock is
      highly contended.

      This patch passes the lock value information gotten in the fast path
      to the slow path to eliminate the additional read. It also documents
      the action for the interrupt context readers more clearly.

      perf record: Let user have timestamps with per-thread recording

      If the option -T is used with option --per-thread, then time is still
      not sampled.  Fix that by using OPT_BOOLEAN_SET to distinguish when the
      user used the -T option as opposed to the default case when timestamps
      are enabled but only for per-cpu recording.

      perf probe: Delete an unnecessary check before the function call 
"strfilter__delete"

      The strfilter__delete() function tests whether its argument is NULL and
      then returns immediately. Thus the test around the call is not needed.

      This issue was detected by using the Coccinelle software.

      perf trace: Use event filters for the event qualifier list

      We use raw_syscalls:sys_{enter,exit} events to show the syscalls, but were
      using a rather lazy/inneficient way to implement our 'strace -e' 
equivalent:
      filter out after reading the events in the ring buffer.

      Deflect more work to the kernel by appending a filter expression for that,
      that, together with the pid list, that is always present, if only to 
filter the
      tracer itself, reduces pressure on the ring buffer and otherwise use
      infrastructure already in place in the kernel to do early filtering.

      If we use it with -v we can see the filter passed to the kernel,
      for instance, for this contrieved case:

        # trace -v -e 
\!open,close,write,poll,recvfrom,select,recvmsg,writev,sendmsg,read,futex,epoll_wait,ioctl,eventfd

      perf evlist: Make perf_evlist__set_filter use perf_evsel__set_filter

      Instead of calling perf_evsel__apply_filter straight away, so that
      we can, in the next patches, expand the filter with more conditions
      before actually calling the ioctl to pass the end result filter to
      the kernel.

      Now we need to call perf_evlist__apply_filters() after the filter
      is completely setup, i.e. do the ioctl calls.

      The perf_evlist__apply_filters() method was already in place, because
      that is the model for the other tools that receives filters in the
      command line: go on setting then in the evsel->filter and only at
      the end, after parsing the whole command line, apply them.

      We get, as a bonus, a more expressive message that states which
      event, if any, failed to have the filter applied to, with an
      error message stating what happened.

      perf evsel: Rename set_filter to apply_filter

      We need to be able to go on constructing a complex filter in multiple
      stages, since we can only set one filter per event.

      For instance, we need to be able, in 'perf trace' to filter by the
      'common_pid' field all the time, if only for the tracer itself, to
      avoid a feedback loop, and, in addition, we may want to filter the
      raw_syscalls:sys_{enter,exit} events by its 'id' filter, when using
      'perf trace -e open,close' or 'perf trace -e !open,close', i.e. when
      we are interested in just a subset of syscalls or when we are not
      interested in it.

      So we will have:

         perf_evsel__set_filter(evsel, char *filter)

             Replaces whatever is in evsel->filter.

         perf_evsel__append_filter(evsel, const char *op, char *filter)

             Appends, using op ("&&" or "||") with what is in evsel->filter.

         perf_evsel__apply_filter(evsel, filter):

              That actually applies a filter, be it the one being
              constructed in evsel->filter, or any other, for tools
              with more specific ways to build the filter, issuing
              the appropriate ioctl for all the evsel fds.

      The same changes will be made to the evlist__{set,apply} variants to
      keep everything consistent.

      Enable the otg controller on Ippo Q8H tablets, for now it is enabled
      in host-only mode, because true OTG support requires support for
      detecting and enabling Vbus through the axp221 pmic.

      For this to work the Vbus on the port must be enabled by u-boot,
      or a powered hub must be used.

      The runtime pm resume/suspend will enable/disable pclk (ISI peripheral
      clock).

      We have to call runtime_pm_get_sync()/runtime_pm_put() when we need to
      access ISI registers. In atmel_isi_probe(), remove the isi disable code
      as at that moment ISI peripheral clock is not enable yet.

      Besides, clock_start()/clock_stop() is used to control the mclk, not
      the ISI peripheral clock. So move this to start[stop]_streaming()
      function.

      Commit 813f5c0ac5cc ("media: Change media device link_notify behaviour")
      modified the media controller link setup notification API and updated the
      OMAP3 ISP driver accordingly. As a side effect it introduced a bug by
      turning power on after setting the link instead of before. This results in

      [media] v4l: omap3isp: Fix async notifier registration order

      The async notifier was registered before the v4l2_device was registered 
and
      before the notifier callbacks were set. This could lead to missing the
      bound() and complete() callbacks and to attempting to spin_lock() and
      uninitialised spin lock.

      Also fix unregistering the async notifier in the case of an error --- the
      function may not fail anymore after the notifier is registered.

      [media] v4l2-dv-timings: add support for reduced blanking v2

      Added support for reduced blanking version 2 (RB v2) in cvt timings.
      Standard specifies a fixed vsync pulse of 8 lines to indicate RB v2
      timings. Vertical back porch is fixed at 6 lines and vertical front
      porch is remainder of vertical blanking time.

      For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync
      is fixed at 32. All horizontal timing counts (active pixels, front,
      back porches) can be specified upto a precision of 1.

      RB v2 allows for non standard aspect ratios. In RB v2 vsync does not
      indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt()
      cannot calculate image width from image height. Hence extending the
      v4l2_detect_cvt() to pass image width in case of RB v2.

      crypto: nx - do not emit extra output if status is disabled

      If the device-tree indicates the nx-842 device's status is 'disabled',
      we emit two messages:

      nx_compress_pseries ibm,compression-v1: nx842_OF_upd_status: status 
'disabled' is not 'okay'.
      nx_compress_pseries ibm,compression-v1: nx842_OF_upd: device disabled

      Given that 'disabled' is a valid state, and we are going to emit that
      the device is disabled, only print out a non-'okay' status if it is not
      'disabled'.

'okay'

      The current documention mentions explicitly that EINVAL should be
      returned if the device is not available, but nx842_OF_upd_status()
      always returns 0. However, nx842_probe() specifically checks for
      non-ENODEV returns from nx842_of_upd() (which in turn calls
      nx842_OF_upd_status()) and emits an extra error in that case. It seems
      like the proper return code of a disabled device is ENODEV.

      drm/i915: Account for CHV/BXT DPLL clock limitations

      CHV/BXT DPLL can't generate frequencies in the 216-240 MHz range.
      Account for that when checking whether the HDMI port clock is valid.
      This is particularly important for BXT since it can otherwise do
      12bpc, and standard 1920x1080p60 CEA modes land right in the middle
      of that range when the clock gets multiplied to account for 12bpc.

      With the extra checks we will now filter out any mode where both
      8bpc and 12bpc clock are within the gap. During modeset we then
      pick whichever mode works, favoring 12bpc if both are possible.

      12bpc isn't supported on CHV so we simply end up filtering out any
      mode where the 8bpc port clock is in the gap.

      ARM: shmobile: R-Car: Break infinite loop

      rcar_sysc_update() loops (with interrupts disabled and while holding a
      spinlock) until submitting a power shutoff or resume request fails, or
      until the submitted request was accepted.
      If none of these conditions becomes true, this forms an infinite loop.

      Put a limit on the maximum number of loop iterations, and add a small
      delay to each iteration, to fix this.

      ARM: shmobile: R-Car: Shrink rcar_sysc_ch size

      Shrink the individual fields in struct rcar_sysc_ch, as unsigned long or
      int is overkill:
        - chan_offs contains a register offset relative to a base value
          (< 512),
        - chan_bit and isr_bit contain bit indices (0-31).

      This reduces the size of each instance from 3 (4 on 64-bit) 32-bit words
      to 1 32-bit word.

      ARM: shmobile: r8a7779: Remove GENPD_FLAG_PM_CLK flag

      The R-Car SYSC PM Domain only manages power domains for the main CPUs
      and for coprocessors. It does not fill in the genpd .{at,de}tach_dev()
      callbacks, and no power management clocks are registered for devices.
      Hence pm_clk_{suspend,resume}() are no-ops, and setting of the
      GENPD_FLAG_PM_CLK flag can be removed.

      Originally the clock handling was copied from the R-Mobile PM Domain
      code, which does manage a clock domain, in addition to device power
      domains.

      ARM: rockchip: fix the CPU soft reset

      We need different orderings when turning a core on and turning a core
      off.  In one case we need to assert reset before turning power off.
      In ther other case we need to turn power on and the deassert reset.

      In general, the correct flow is:

      CPU off:
          reset_control_assert
          regmap_update_bits(pmu, PMU_PWRDN_CON, BIT(pd), BIT(pd))
          wait_for_power_domain_to_turn_off
      CPU on:
          regmap_update_bits(pmu, PMU_PWRDN_CON, BIT(pd), 0)
          wait_for_power_domain_to_turn_on
          reset_control_deassert

      This is needed for stressing CPU up/down, as per:
          cd /sys/devices/system/cpu/
          for i in $(seq 10000); do
              echo "================= $i ============"
              for j in $(seq 100); do
                  while [[ "$(cat cpu1/online)$(cat cpu2/online)$(cat 
cpu3/online)" != "000"" ]]
                      echo 0 > cpu1/online
                      echo 0 > cpu2/online
                      echo 0 > cpu3/online
                  done
                  while [[ "$(cat cpu1/online)$(cat cpu2/online)$(cat 
cpu3/online)" != "111" ]]; do
                      echo 1 > cpu1/online
                      echo 1 > cpu2/online
                      echo 1 > cpu3/online
                  done
              done
          done

      The following is reproducable log:
          [34466.186812] PM: noirq suspend of devices complete after 0.669 msecs

          <hang>

          Tested by cpu up/down scripts, the results told us need delay more 
time
      before write the sram. The wait time is affected by many aspects
      (e.g: cpu frequency, bootrom frequency, sram frequency, bus speed, ...).

          Although the cpus other than cpu0 will write the sram, the speedy is
      no the same as cpu0, if the cpu0 early wake up, perhaps the other cpus
      can't startup. As we know, the cpu0 can wake up when the cpu1/2/3 write
      the 'sram+4/8' and send the sev.
          Anyway.....
          At the moment, 1ms delay will be happy work for cpu up/down scripts 
test.

      ARM: rockchip: restore dapswjdp after suspend

      In the commit (0ea001d ARM: rockchip: disable dapswjdp during suspend)
      we made the assumption that we didn't need to restore dapswjdp after
      suspend because "the MASKROM will enable it back".

      It turns out that's not a safe assumption.  In some cases (pending
      interrupts) it's possible that the WFI might act as a no-op and the
      MaskROM will never run.  Since we're changing the bit, we should
      restore it ourselves.

          drm/crtc_helper: Replace open-coded CRTC state helpers

      error handling code was broken, resulting in the first path not being

      v2: Simplify the cleanup code while at it too.

      without necessarily calling i915_gem_stolen_setup_compression() first,

      drm/i915: Reserve space improvements

      An earlier patch was added to reserve space in the ring buffer for the
      commands issued during 'add_request()'. The initial version was
      pessimistic in the way it handled buffer wrapping and would cause
      premature wraps and thus waste ring space.

      This patch updates the code to better handle the wrap case. It no
      longer enforces that the space being asked for and the reserved space
      are a single contiguous block. Instead, it allows the reserve to be on
      the far end of a wrap operation. It still guarantees that the space is
      available so when the wrap occurs, no wait will happen. Thus the wrap
      cannot fail which is the whole point of the exercise.

      Also fixed a merge failure with some comments from the original patch.

      v2: Incorporated suggestion by David Gordon to move the wrap code
      inside the prepare function and thus allow a single combined
      wait_for_space() call rather than doing one before the wrap and
      another after. This also makes the prepare code much simpler and
      easier to follow.

      v3: Fix for 'effective_size' vs 'size' during ring buffer remainder
      calculations (spotted by Tomas Elf).

      drm: Reject DRI1 hw lock ioctl functions for kms drivers

      I've done some extensive history digging across libdrm, mesa and
      xf86-video-{intel,nouveau,ati}. The only potential user of this with
      kms drivers I could find was ttmtest, which once used drmGetLock
      still. But that mistake was quickly fixed up. Even the intel xvmc
      library (which otherwise was really good with using dri1 stuff in kms
      mode) managed to never take the hw lock for dri2 (and hence kms).

      Hence it should be save to unconditionally disallow this.

      ath10k: configure frag desc memory to target for qca99X0

      Pre qca99X0 chipsets follows the model where dynamically allocate
      memory for frag desc on getting new skb for TX. But, this is not
      going to be the case in qca99X0. It expects frag desc memory to be
      allocated at boot time and let the driver to reuse allocated memory
      after every TX completion. So there won't be any dynamic frag memory
      memory allocation in qca99X0 during data transmission.

      qca99X0 hardware doesn't need fragment desc address to be programmed
      in msdu descriptor for every data transaction. It needs to know only
      starting address of fragment descriptor at the time of the boot.
      During data transmission, qca99X0 hardware can retrieve corresponding
      frag addr by adding programmed frag desc base addr + msdu id.

      Allocate continuous fragment descriptor memory (same size as number of
      descriptor) at the time of target initialization and configure allocated
      dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.

      How this is allocated continuous memory is going to be used is not
      covered in this patch. It just allocates memory and hand over to firmware.
      If we don't do it at init time, qca99X0 will stall when firmware tries
      to do TX.

      10.4 firmware swba event payload has space to accommodate upto
      512 client traffic indication info & one p2p noa descriptor.
      It's is not matching with exiting swba event format defined for
      non 10.4 firmware. Non 10.4 firmware swba event format is designed

       - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba

       - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

      ath10k: enhance swba event handler to adapt different size tim bitmap

      Due to 512 client support in 10.4 firmware, size of tim ie is going
      to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
      what is carried in swba event from 10.4 firmware is bit higher.

      The only bottle neck to reuse existing swba handler
      ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
      with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
      This patch removes such size limitation and makes it more suitable
      to handle swba event which has different size tim bitmap.

      All existing swba event parsing functions are changed to adapt this
      change. Actual support to handle 10.4 swba event is added in next patch.
      Only preparation is made in this patch.

      wil6210: restart AP upon change in privacy settings

      privacy settings might change while AP is running.
      Inside wil_cfg80211_change_beacon(), detect change
      in privacy settings and handle it by stopping and
      re-starting the AP.
      Firmware cannot handle on-the-fly privacy settings
      change and so AP restart is required.

      ath: DFS - limit number of potential PRI sequences

      In the PRI detector, after the current radar pulse
      has been checked agains existing PRI sequences, it
      is considered as part of a new potential sequence.

      Previously, the condition to accept a new sequence
      was to have at least the same number of pulses as
      the longest matching sequence. This was wrong,
      since it led to duplicates of PRI sequences.

      This patch changes the acceptance criteria for new
      potential sequences from 'at least' to 'more than'
      the longest existing.

      Detection performance remains unaffected, while
      the number of PRI sequences accounted at runtime
      (and with it CPU load) is reduced by up to 50%.

      Depending on the platform the port clock fed to the pipe can be the PLL's
      post-divided fast clock rate or a /5 divided version of it. To make this
      more obvious across the platforms calculate this port clock along with
      the rest of the PLL parameters.

      This is also needed by the next patch where we can reuse the CHV helper
      for the BXT PLL HW readout code; so export the corresponding helper.

      While at it also add a more descriptive name to the helpers and a

      drm/i915: Don't do PM5/DDR DVFS with multiple pipes

      Enabling PM5/DDR DVFS with multiple active pipes isn't a validated
      configuration. It does seem to work most of the time at least, but
      there is clearly an additional risk of underruns, so let's not play
      with fire.

      drm/i915: Try to make sure cxsr is disabled around plane enable/disable

      CxSR (or maxfifo on VLV/CHV) blocks somne changes to the plane control
      register (enable bit at least, not quite sure about the rest). So in
      order to have the plane enable/disable when we want we need to first
      kick the hardware out of cxsr.

      Unfortunateloy this requires some extra vblank waits. For the CxSR
      enable after the plane update we should eventually use an async
      vblank worker, but since we don't have that just do sync vblank
      waits. For the disable case we have no choice but to do it
      synchronously.

      drm/i915: Use the memory latency based WM computation on VLV too

      In order to get decnet memory self refresh residency on VLV, flip it
      over to the new CHV way of doing things. VLV doesn't do PM5 or DDR DVFS
      so it's a bit simpler.

      I'm not sure the currently memory latency used for CHV is really
      appropriate for VLV. Some further testing will probably be needed to
      figure that out.

      drm/i915: Compute display FIFO split dynamically for CHV

      Consider which planes are active and compute the FIFO split based on the
      relative data rates. Since we only consider the pipe src width rather
      than the plane width when computing watermarks it seems best to do the
      same when computing the FIFO split as well. This means the only thing we
      actually have to consider for the FIFO splut is the bpp, and we can
      ignore the rest.

      I've just stuffed the logic into the watermark code for now. Eventually
      it'll need to move into the atomic update for the crtc.

      There's also one extra complication I've not yet considered; Some of the
      DSPARB registers contain bits related to multiple pipes. The registers
      are double buffered but apparently they update on the vblank of any
      active pipe. So doing the FIFO reconfiguration properly when multiple
      pipes are active is not going to be fun. But let's ignore that mess for
      now.

      drm/i915: CHV DDR DVFS support and another watermark rewrite

      Turns out the VLV/CHV system agent doesn't understand memory
      latencies, so trying to rely on the PND deadline mechanism is not
      going to fly especially when DDR DVFS is enabled. Currently we try to
      avoid the problems by lying to the system agent about the deadlines
      and setting the FIFO watermarks to 8 cachelines. This however leads to
      bad memory self refresh residency.

      So in order to satosfy everyone we'll just give up on the deadline
      scheme and program the watermarks old school based on the worst case
      memory latency.

      I've modelled this a bit on the ILK+ approach where we compute multiple
      sets of watermarks for each pipe (PM2,PM5,DDR DVFS) and when merge thet
      appropriate one later with the watermarks from other pipes. There isn't
      too much to merge actually since each pipe has a totally independent
      FIFO (well apart from the mess with the partially shared DSPARB
      registers), but still decopuling the pipes from each other seems like a
      good idea.

      Eventually we'll want to perform the watermark update in two phases
      around the plane update to avoid underruns due to the single buffered
      watermark registers. But that's still in limbo for ILK+ too, so I've not
      gone that far yet for VLV/CHV either.

      BSpec: "IPS cannot be enabled until after at least one plane has
      been enabled for at least one vertical blank." and "IPS must be
      disabled while there is still at least one plane enabled on the
      same pipe as IPS." This restriction apply to HSW and BDW.

      However a shortcut path on update primary plane function
      to make primary plane invisible by setting DSPCTRL to 0
      was leting IPS enabled while there was no
      other plane enabled on the pipe causing flickerings that we were
      believing that it was caused by that other restriction where
      ips cannot be used when pixel rate is greater than 95% of cdclok.

      drm/i915/skl: Replace the HDMI DPLL divider computation algorithm

      The HW validation team came back from further testing with a slightly
      changed constraint on the deviation between the DCO frequency and the
      central frequency. Instead of +-4%, it's now +1%/-6%.

      Unfortunately, the previous algorithm didn't quite cope with these new
      constraints, the reason being that it wasn't thorough enough looking at
      the possible divider candidates.

      The new algorithm looks at all dividers, which is definitely a hammer
      approach (we could reduce further the set of dividers to good ones as a
      follow up, at the cost of a bit more complicated code). But, at least,
      we can now satisfy the +1%/+6% rule for all the "Well known" HDMI
      frequencies of my test set (373 entries).

      On that subject, the new code is quite extensively tested in
      intel-gpu-tools (tools/skl_compute_wrpll).

      v2: Fix cycling between central frequencies and dividers (Paulo)
          Properly choose the minimal deviation between postive and negative
          candidates (Paulo).

          On the 373 test frequencies, v2 computes better dividers than v1 (ie
          more even dividers and lower deviation on average):

          v1: average deviation: 206.52
          v2: average deviation: 194.47

      drm/i915/gtt: Pin vma during virtual address allocation

      Dynamic page table allocation might wake the shrinker
      when memory is requested for page table structures.
      As this happens when we try to allocate the virtual address
      during binding, our vma might be among the targets for eviction.
      We should do i915_vma_pin() and do pin early in there like Chris
      suggests but this is interim solution.

      Shield our vma from shrinker by incrementing pin count before
      the virtual address is allocated.

      The proper place to fix this would be in gem, inside of
      i915_vma_pin(). But we don't have that yet so take the short
      cut as a intermediate solution.

      As there is flushing involved when we have done the cpu
      write, make functions for mapping for cpu space. Make macros
      to map any type of paging structure.

      v2: Make it clear tha flushing kunmap is only for ppgtt (Ville)
      v3: Flushing fixed (Ville, Michel). Removed superfluous semicolon

      computation flow that's no longer the case.

      Rename them to avoid further confusion.

      Note that the ilk code already follows the compute_dpll naming scheme
      for computing the actual register value. DDI code goes with _calc_,
      but that is close enough.

      have to filter flush calls due to e.g. gpu rendering. Filter these
      out.

      drm/i915: Clear fb_tracking.busy_bits also for synchronous flips

      The current/old frontbuffer might still have gpu frontbuffer rendering
      pending. But once flipped it won't have the corresponding frontbuffer
      bits any more and hence the request retire function won't ever clear
      the corresponding busy bits. The async flip tracking (with the
      flip_prepare and flip_complete functions) already does this, but
      somehow I've forgotten to do this for synchronous flips.

      Note that we don't track outstanding rendering of the new framebuffer
      with busy_bits since all our plane update code waits for previous
      rendering to complete before displaying a new buffer. Hence a new
      buffer will never be busy.

      v2: Drop the spurious inline Ville spotted.

      v3: Don't touch flip_bits in the synchronsou frontbuffer_flip
      function, noticed by Paulo.

      v4: Remove one more inline that slipped through (Paulo).

      drm/i915: Update a bunch of LRC functions to take requests

      A bunch of the low level LRC functions were passing around ringbuf and ctx
      pairs. In a few cases, they took the r/c pair and a request as well. This 
is all
      quite messy and unnecesary. The context_queue() call is especially bad 
since the
      fake request code got removed - it takes a request and three extra things 
that
      must be extracted from the request and then it checks them against what 
it finds
      in the request. Removing all the derivable data makes the code much 
simpler all
      round.

      This patch updates those functions to just take the request structure.

      Note that logical_ring_wait_for_space now takes a request structure but 
already
      had a local request pointer that it uses to scan for something to wait 
on. To
      avoid confusion the local variable has been renamed 'target' (it is 
searching
      for a target request to do something with) and the parameter has been 
called req
      (to guarantee anything accidentally missed gets a compiler error).

      v2: Updated commit message re wait_for_space (Tomas Elf review comment).

      drm/i915: Remove 'faked' request from LRC submission

      The LRC submission code requires a request for tracking purposes. It does 
not
      actually require that request to 'complete' it simply uses it for keeping 
hold
      of reference counts on contexts and such like.

      Previously, the fall back path of polling for space in the ring would 
start by
      submitting any outstanding work that was sat in the buffer. This 
submission was
      not done as part of the request that that work was owned by because that 
would
      lead to complications with the request being submitted twice. Instead, a 
null
      request structure was passed in to the submit call and a fake one was 
created.

      That fall back path has long since been obsoleted and has now been 
removed. Thus
      there is never any need to fake up a request structure. This patch 
removes that
      code. A couple of sanity check warnings are added as well, just in case.

      drm/i915: Move the request/file and request/pid association to creation 
time

      In _i915_add_request(), the request is associated with a userland client.
      Specifically it is linked to the 'file' structure and the current user 
process
      is recorded. One problem here is that the current user process is not
      necessarily the same as when the request was submitted to the driver. 
This is
      especially true when the GPU scheduler arrives and decouples driver 
submission
      from hardware submission. Note also that it is only in the case where the 
add
      request comes from an execbuff call that there is a client to associate. 
Any
      other add request call is kernel only so does not need to do it.

      This patch moves the client association into a separate function. This is 
then
      called from the execbuffer code path itself at a sensible time. It also 
removes
      the now redundant 'file' pointer from the add request parameter list.

      An extra cleanup of the client association is also added to the request 
clean up
      code for the eventuality where the request is killed after association but
      before being submitted (e.g. due to out of memory error somewhere). Once 
the
      submission has happened, the request is on the request list and the 
regular
      request list removal will clear the association. Note that this still 
needs to
      happen at this point in time because the request might be kept floating 
around
      much longer (due to someone holding a reference count) and the client 
should not
      be worrying about this request after it has been retired.

      drm/i915: Update queue_flip() to take a request structure

      Updated the display page flip code to do explicit request creation and
      submission rather than relying on the OLR and just hoping that the request
      actually gets submitted at some random point.

      The sequence is now to create a request, queue the work to the ring, 
assign the
      known request to the flip queue work item then actually submit the work 
and post
      the request.

      Note that every single flip function used to finish with
      '__intel_ring_advance(ring);'. However, immediately after they return 
there is
      now an add request call which will do the advance anyway. Thus the many
      duplicate advance calls have been removed.

      v2: Updated commit message with comment about advance removal.

      v3: The request can now be allocated by the _sync() code earlier on. Thus 
the
      page flip path does not necessarily need to allocate a new request, it 
may be
      able to re-use one.

      drm/i915: Update i915_gem_object_sync() to take a request structure

      The plan is to pass requests around as the basic submission tracking 
structure
      rather than rings and contexts. This patch updates the 
i915_gem_object_sync()
      code path.

      v2: Much more complex patch to share a single request between the sync 
and the
      page flip. The _sync() function now supports lazy allocation of the 
request
      structure. That is, if one is passed in then that will be used. If one is 
not,
      then a request will be allocated and passed back out. Note that the 
_sync() code
      does not necessarily require a request. Thus one will only be created 
until
      certain situations. The reason the lazy allocation must be done within the
      _sync() code itself is because the decision to need one or not is not 
really
      something that code above can second guess (except in the case where one 
is
      definitely not required because no ring is passed in).

      The call chains above _sync() now support passing a request through which 
most
      callers passing in NULL and assuming that no request will be required 
(because
      they also pass in NULL for the ring and therefore can't be generating any 
ring
      code).

      The exeception is intel_crtc_page_flip() which now supports having a 
request
      returned from _sync(). If one is, then that request is shared by the page 
flip
      (if the page flip is of a type to need a request). If _sync() does not 
generate
      a request but the page flip does need one, then the page flip path will 
create
      its own request.

      v3: Updated comment description to be clearer about 'to_req' parameter 
(Tomas
      Elf review request). Rebased onto newer tree that significantly changed 
the
      synchronisation code.

      v4: Updated comments from review feedback (Tomas Elf)

      drm/i915: Update deferred context creation to do explicit request 
management

      In execlist mode, context initialisation is deferred until first use of 
the
      given context. This is because execlist mode has per ring context state 
and thus
      many more context storage objects than legacy mode and many are never 
actually
      used. Previously, the initialisation commands were written to the ring and
      tagged with some random request structure via the OLR. This seemed to be 
causing
      a null pointer deference bug under certain circumstances (BZ:88865).

      This patch adds explicit request creation and submission to the deferred
      initialisation code path. Thus removing any reliance on or randomness 
caused by
      the OLR.

      Note that it should be possible to move the deferred context creation 
until even
      later - when the context is actually switched to rather than when it is 
merely
      validated. This would allow the initialisation to be done within the 
request of
      the work that is wanting to use the context. Hence, the extra request 
that is
      created, used and retired just for the context init could be removed 
completely.
      However, this is left for a follow up patch.

      switch's context. As the context switch now gets the context object from 
the

      drm/i915: Don't tag kernel batches as user batches

call to

buffer to

entry in

for

      hangs.

      The i915_gem_init_hw() function calls a bunch of smaller initialisation

This

the ring
      which floats around in that ring's OLR until some random point in the

      drm/i915: Update alloc_request to return the allocated request

      The alloc_request() function does not actually return the newly allocated
      request. Instead, it must be pulled from ring->outstanding_lazy_request. 
This
      patch fixes this so that code can create a request and start using it 
knowing
      exactly which request it actually owns.

      v2: Updated for new i915_gem_request_alloc() scheme.

      drm/i915: Merged the many do_execbuf() parameters into a structure

      The do_execbuf() function takes quite a few parameters. The actual set of
      parameters is going to change with the conversion to passing requests 
around.
      Further, it is due to grow massively with the arrival of the GPU 
scheduler.

      This patch simplifies the prototype by passing a parameter structure 
instead.
      Changing the parameter set in the future is then simply a matter of
      adding/removing items to the structure.

      Note that the structure does not contain absolutely everything that is 
passed
      in. This is because the intention is to use this structure more 
extensively
      later in this patch series and more especially in the GPU scheduler that 
is
      coming soon. The latter requires hanging on to the structure as the final
      hardware submission can be delayed until long after the execbuf IOCTL has
      returned to user land. Thus it is unsafe to put anything in the structure 
that
      is local to the IOCTL call itself - such as the 'args' parameter. All 
entries
      must be copies of data or pointers to structures that are reference 
counted in
      some way and guaranteed to exist for the duration of the batch buffer's 
life.

      v2: Rebased to newer tree and updated for changes to the command parser.
      Specifically, a code shuffle has required saving the batch start address 
in the
      params structure.

      drm/i915: Set context in request from creation even in legacy mode

      In execlist mode, the context object pointer is written in to the request
      structure (and reference counted) at the point of request creation. In 
legacy
      mode, this only happens inside i915_add_request().

      This patch updates the legacy code path to match the execlist version. 
This
      allows all the intermediate code between request creation and request 
submission
      to get at the context object given only a request structure. Thus 
negating the
      need to pass context pointers here, there and everywhere.

      v2: Moved the context reference so it does not need to be undone if the
      get_seqno() fails.

      v3: Fixed execlist mode always hitting a warning about invalid 
last_contexts
      (which don't exist in execlist mode).

      v4: Updated for new i915_gem_request_alloc() scheme.

      drm/i915: Early alloc request in execbuff

      Start of explicit request management in the execbuffer code path. This 
patch
      adds a call to allocate a request structure before all the actual 
hardware work
      is done. Thus guaranteeing that all that work is tagged by a known 
request. At
      present, nothing further is done with the request, the rest comes later 
in the
      series.

      The only noticable change is that failure to get a request (e.g. due to 
lack of
      memory) will be caught earlier in the sequence. It now occurs right at 
the start
      before any un-undoable work has been done.

      drm/i915: i915_add_request must not fail

      The i915_add_request() function is called to keep track of work that has 
been
      written to the ring buffer. It adds epilogue commands to track progress 
(seqno
      updates and such), moves the request structure onto the right list and 
other
      such house keeping tasks. However, the work itself has already been 
written to
      the ring and will get executed whether or not the add request call 
succeeds. So
      no matter what goes wrong, there isn't a whole lot of point in failing 
the call.

      At the moment, this is fine(ish). If the add request does bail early on 
and not
      do the housekeeping, the request will still float around in the
      ring->outstanding_lazy_request field and be picked up next time. It means
      multiple pieces of work will be tagged as the same request and driver 
can't
      actually wait for the first piece of work until something else has been
      submitted. But it all sort of hangs together.

      This patch series is all about removing the OLR and guaranteeing that 
each piece
      of work gets its own personal request. That means that there is no more
      'hoovering up of forgotten requests'. If the request does not get tracked 
then
      it will be leaked. Thus the add request call _must_ not fail. The 
previous patch
      should have already ensured that it _will_ not fail by removing the 
potential
      for running out of ring space. This patch enforces the rule by actually 
removing
      the early exit paths and the return code.

      Note that if something does manage to fail and the epilogue commands 
don't get
      written to the ring, the driver will still hang together. The request 
will be
      added to the tracking lists. And as in the old case, any subsequent work 
will
      generate a new seqno which will suffice for marking the old one as 
complete.

      v2: Improved WARNings (Tomas Elf review request).

      drm/i915: Reserve ring buffer space for i915_add_request() commands

      It is a bad idea for i915_add_request() to fail. The work will already 
have been
      send to the ring and will be processed, but there will not be any 
tracking or
      management of that work.

      The only way the add request call can fail is if it can't write its 
epilogue
      commands to the ring (cache flushing, seqno updates, interrupt 
signalling). The
      reasons for that are mostly down to running out of ring buffer space and 
the
      problems associated with trying to get some more. This patch prevents that
      situation from happening in the first place.

      When a request is created, it marks sufficient space as reserved for the
      epilogue commands. Thus guaranteeing that by the time the epilogue is 
written,
      there will be plenty of space for it. Note that a ring_begin() call is 
required
      to actually reserve the space (and do any potential waiting). However, 
that is
      not currently done at request creation time. This is because the 
ring_begin()
      code can allocate a request. Hence calling begin() from the request 
allocation
      code would lead to infinite recursion! Later patches in this series 
remove the
      need for begin() to do the allocate. At that point, it becomes safe for 
the
      allocate to call begin() and really reserve the space.

      Until then, there is a potential for insufficient space to be available 
at the
      point of calling i915_add_request(). However, that would only be in the 
case
      where the request was created and immediately submitted without ever 
calling
      ring_begin() and adding any work to that request. Which should never 
happen. And
      even if it does, and if that request happens to fall down the tiny window 
of
      opportunity for failing due to being out of ring space then does it really
      matter because the request wasn't doing anything in the first place?

      v2: Updated the 'reserved space too small' warning to include the 
offending
      sizes. Added a 'cancel' operation to clean up when a request is 
abandoned. Added
      re-initialisation of tracking state after a buffer wrap to keep the sanity
      checks accurate.

      v3: Incremented the reserved size to accommodate Ironlake (after finally
      managing to run on an ILK system). Also fixed missing wrap code in LRC 
mode.

      v4: Added extra comment and removed duplicate WARN (feedback from Tomas).

      drm/i915/gen8: Add infrastructure to initialize WA batch buffers

      Some of the WA are to be applied during context save but before restore 
and
      some at the end of context save/restore but before executing the 
instructions
      in the ring, WA batch buffers are created for this purpose and these WA 
cannot
      be applied using normal means. Each context has two registers to load the
      offsets of these batch buffers. If they are non-zero, HW understands that 
it
      need to execute these batches.

      v1: In this version two separate ring_buffer objects were used to load WA
      instructions for indirect and per context batch buffers and they were part
      of every context.

      v2: Chris suggested to include additional page in context and use it to 
load
      these WA instead of creating separate objects. This will simplify lot of 
things
      as we need not explicity pin/unpin them. Thomas Daniel further pointed 
that GuC
      is planning to use a similar setup to share data between GuC and driver 
and
      WA batch buffers can probably share that page. However after discussions 
with
      Dave who is implementing GuC changes, he suggested to use an independent 
page
      for the reasons - GuC area might grow and these WA are initialized only 
once and
      are not changed afterwards so we can share them share across all contexts.

      The page is updated with WA during render ring init. This has an 
advantage of
      not adding more special cases to default_context.

      We don't know upfront the number of WA we will applying using these batch 
buffers.
      For this reason the size was fixed earlier but it is not a good idea. To 
fix this,
      the functions that load instructions are modified to report the no of 
commands
      inserted and the size is now calculated after the batch is updated. A 
macro is
      introduced to add commands to these batch buffers which also checks for 
overflow
      and returns error.
      We have a full page dedicated for these WA so that should be sufficient 
for
      good number of WA, anything more means we have major issues.
      The list for Gen8 is small, same for Gen9 also, maybe few more gets added
      going forward but not close to filling entire page. Chris suggested a 
two-pass
      approach but we agreed to go with single page setup as it is a one-off 
routine
      and simpler code wins.

      One additional option is offset field which is helpful if we would like to
      have multiple batches at different offsets within the page and select them
      based on some criteria. This is not a requirement at this point but could
      help in future (Dave).

      Chris provided some helpful macros and suggestions which further 
simplified
      the code, they will also help in reducing code duplication when WA for
      other Gen are added. Add detailed comments explaining restrictions.
      Use do {} while(0) for wa_ctx_emit() macro.

      drm/i915: Ignore LVDS presence in VBT flag if the LVDS is enabled by BIOS

      On older gen, pre-Ironlake, parts there is no hardwired pin to report
      the presence of an LVDS panel. Instead, we have to rely on the VBT to
      declare whether the machine has a panel or not. Though notoriously
      unreliable, so far we have erred on the side of false-positives and have
      required a list of machines which end up falsely reporting a panel as
      present. However, we now have reports of false-negatives, machines with
      an LVDS that are being ignored due to the VBT not declaring the panel.
      This patch ignores the VBT setting if the BIOS has already enabled the
      LVDS panel (and on Ironlake+ we also have the hardware presence pin).

      It fixes the Samsung NP680Z5E-X01FR in the bug report, but is likely to
      result in more false-positives, and since we rely on the BIOS to enable
      the panel, there are likely different circumstances where the BIOS will
      not enable that panel (and so we may see the same machine with and
      without a panel all on the whim of the BIOS).

      This patch doesn't have any functional change, but organize fruntbuffer
      invalidate and busy by removing unecesarry signature argument for ring.

      It was unsed on mark_fb_busy and only used on fb_obj_invalidate for the
      same ORIGIN_CS usage. So let's clean it a bit

      drm/i915: move generic hotplug code into new intel_hotplug.c file

      We have enough generic hotplug functions sprinkled all over i915_irq.c
      to warrant moving them to a file of their own. This should further
      underline the distinction between generic code in the new file and
      platform specific hotplug and irq code that remains in i915_irq.c.

      Add new intel_hpd_init_work to keep work functions static, and rename
      get_port_from_pin to intel_hpd_pin_to_port while increasing its
      visibility, but keep everything else the same.

      The hotplug work function has two loops iterating over connectors, the
      first for handling hotplug disabling due to irq storms and the second
      for actually handling the hotplug events. Move the debug printing into

      drm/i915: atomic plane updates in a nutshell

      Now that all planes are added during a modeset we can use the
      calculated changes before disabling a plane, and then either commit
      or force disable a plane before disabling the crtc.

      The code is shared with atomic_begin/flush, except watermark updating
      and vblank evasion are not used.

      This is needed for proper atomic suspend/resume support.

      drm/i915: Handle disabling planes better, v2.

      Read out the initial state, and add a quirk to force add all planes
      to crtc_state->plane_mask during initial commit. This will disable
      all planes during the initial modeset.

      The initial plane quirk is temporary, and will go away when hardware
      readout is fully atomic, and the watermark updates in intel_sprite.c
      are removed.

      Changes since v1:
      - Unset state->visible on !primary planes.
      - Do not rely on the plane->crtc pointer in intel_atomic_plane,
        instead assume planes are invisible until modeset.

      iio: allow userspace to flush the hwfifo with non-blocking reads

      This patch changes the semantics of non-blocking reads so that a
      hardware fifo flush is triggered if the available data in the device
      buffer is less then the requested size.

      This allows userspace to accurately generate hardware fifo flushes, by
      doing a non-blocking read with a size greater then the sum of the
      device buffer and hardware fifo size.

      drm/i915: Reset request handling for gen8+

      In order for gen8+ hardware to guarantee that no context switch
      takes place during engine reset and that current context is properly
      saved, the driver needs to notify and query hw before commencing
      with reset.

      There are gpu hangs where the engine gets so stuck that it never will
      report to be ready for reset. We could proceed with reset anyway, but
      with some hangs with skl, the forced gpu reset will result in a system
      hang. By inspecting the unreadiness for reset seems to correlate with
      the probable system hang.

      We will only proceed with reset if all engines report that they
      are ready for reset. If root cause for system hang is found and
      can be worked around with another means, we can reconsider if
      we can reinstate full reset for unreadiness case.

      drm/i915/bxt: eDP Panel Power sequencing

      Changes for BXT - added a IS_BROXTON check to use the macro related to PPS
      registers for BXT.
      BXT does not have PP_DIV register. Making changes to handle this.
      Second set of PPS registers have been defined but will be used when VBT
      provides a selection between the 2 sets of registers.

      v2:
      [Jani] Added 2nd set of PPS registers and the macro
      Jani's review comments
        - remove reference in i915_suspend.c
        - Use BXT PP macro
      Squashing all PPS related patches into one.

      v3: Jani's review comments addressed
        - Use pp_ctl instead of pp
        - ironlake_get_pp_control() is not required for BXT
        - correct the use of && in the print statement
        - drop the shift in the print statement

      v4: Jani's comments
        - modify ironlake_get_pp_control() - dont set unlock key for bxt

      v5: Sonika's comments addressed
        - check alignment
        - move pp_ctrl_reg write (after ironlake_get_pp_control())
        to !IS_BROXTON case.
        - check before subtracting 1 for t11_t12

      drm/i915: don't set the FBC plane select bits on HSW+

      This commit is just to make the intentions explicit: on HSW+ these
      bits are MBZ, but since we only support plane A and the macro
      evaluates to zero when plane A is the parameter, we're not fixing any
      bug.

      v2:
       - Remove useless extra blank like (Chris).
       - Init dpfc_ctl in another place (Chris).

      drm/i915: Drop the 64k linear scanout alignment on gen2/3

      The docs don't support the 64k linear scanout alignment we impose
      on gen2/3. And it really makes no sense since we have no DSPSURF
      register, so the only thing that the hardware will see is the linear
      offset which will be just pixel aligned anyway.

      There is one case where 64k comes into the picture, and that's FBC.
      The start of the line length buffer corresponds to a 64k aligned
      address of the uncompressed framebuffer. So if the uncompressed fb is
      not 64k aligned, the first actually used entry in the line length
      buffer will not be byte 0. There are 32 extra entries in the line
      length buffer to account for this extra alignment so we shouldn't
      have to worry about it when mapping the uncompressed fb to the GTT.

      drm/i915: Align DSPSURF to 128k on VLV/CHV

      VLV/CHV have problems with 4k aligned linear scanout buffers. The VLV
      docs got updated at some point to say that we need to align them to
      128k, just like we do on gen4.

      So far I've seen the problem manifest when the stride is an odd multiple
      of 512 bytes, and the surface address meets the following pattern
      '(addr & 0xf000) == 0x1000' (also == 0x2000 is problematic on VLV). The
      result is a starcase effect (so some pages get dropped maybe?), with a
      few pages here and there clearly getting scannout out at the wrong 
position.

      I've not actually been able to reproduce this problem on gen4, so it's
      not clear of the issue is any way related to the 128k restrictions
      supposedly inherited from gen4. But let's hope the 128k alignment is
      sufficient to hide it all.

      drm/i915: Actually respect DSPSURF alignment restrictions

      Currently intel_gen4_compute_page_offset() simply picks the closest
      page boundary below the linear offset. That however may not be suitably
      aligned to satisfy any hardware specific restrictions. So let's make
      sure the page boundary we choose is properly aligned.

      Also to play it a bit safer lets split the remaining linear offset into
      x and y values instead of just x. This should make no difference for
      most platforms since we convert the x and y offsets back into a linear
      offset before feeding them to the hardware. HSW+ are different however
      and use x and y offsets even with linear buffers, so they might have
      trouble if either the x or y get too big.

      This can also be usefully extended in future to indicate different

      scripts/package/Makefile: rpmbuild is needed for rpm targets

      Before rpm release 4.1, in 2002, either the rpm command or the
      rpmbuild command could be used in the rpm-pkg or binrpm-pkg targets,
      and the Makefile chose the rpm command if the rpmbuild command wasn't
      found.

      After release 4.1, however, the rpm command could no longer be used in
      place of the rpmbuild command.  As the rpmbuild command is not
      installed by default, this can lead to failures with the rpm-pkg and
      binrpm-pkg targets:

      rpm --define "_builddir ." --target \
          x86_64 -bb ./binkernel.spec
          rpm --target: unknown option
          scripts/package/Makefile:60: recipe for target 'binrpm-pkg' failed

      Change the Makefile to use rpmbuild unconditionally to avoid this.

      Only bit 27 of SCRATCH1 and bit 6 of ROW_CHICKEN3 are allowed to be
      set because of security-sensitive bits we don't want userspace to mess
      with.  On HSW hardware the whitelisted bits control whether atomic
      read-modify-write operations are performed on L3 or on GTI, and when
      set to L3 (which can be 10x-30x better performing than on GTI,
      depending on the application) require great care to avoid a system
      hang, so we currently program them to be handled on GTI by default.

      Beignet can immediately start taking advantage of this change to
      enable L3 atomics.  Mesa should eventually switch to L3 atomics too,
      but a number of non-trivial changes are still required so it will
      continue using GTI atomics for now.

      In some cases it might be unnecessary or dangerous to give userspace
      the right to write arbitrary values to some register, even though it

      extends the register whitelist entries to contain a mask/value pair in
      addition to the register offset.  For registers with non-zero mask,
      any LRM writes and LRI writes where the bits of the immediate given by
      the mask don't match the specified value will be rejected.

      This will be used in my next patch to grant userspace partial write

      drm/i915: Fix command parser to validate multiple register access with 
the same command.

      Until now the software command checker assumed that commands could
      read or write at most a single register per packet.  This is not
      necessarily the case, MI_LOAD_REGISTER_IMM expects a variable-length
      list of offset/value pairs and writes them in sequence.  The previous
      code would only check whether the first entry was valid, effectively
      allowing userspace to write unrestricted registers of the MMIO space
      by sending a multi-register write with a legal first register, with
      potential security implications on Gen6 and 7 hardware.

      Fix it by extending the drm_i915_cmd_descriptor table to represent
      multi-register access and making validate_cmd() iterate for all
      register offsets present in the command packet.

      drm/i915: Double the port clock when using double clocked modes with 12bpc

      Currently we're forgetting to double the port clock when using double
      clocked modes with 12bpc on HDMI. We're only accounting for the 1.5x
      factor due to the 12bpc. So further double the 1.5x port clock when we
      have a double clocked mode.

      Unfortunately I don't have any displays that support both 12bpc and
      double clocked modes, so I was unable to test this.

      drm/i915: Check infoframe state more diligently.

      Check that the DIP is enabled on the right port on IBX and VLV/CHV as
      we're doing on g4x, and also check for all the infoframe enable bits on
      all platforms.

      Eventually we should track each infoframe type independently, and also
      their contents. This is a small step in that direction as 
.infoframe_enabled()
      return value could be easily turned into a bitmask.

      drm/i915: Disable all infoframes when turning off the HDMI port

      Currently we just disable the GCP infoframe when turning off the port.
      That means if the same transcoder is used on a DP port next, we might
      end up pushing infoframes over DP, which isn't intended. Just disable
      all the infoframes when turning off the port.

      Also protect against two ports stomping on each other on g4x due to
      the single video DIP instance. Now only the first port to enable
      gets to send infoframes.

      drm/i915: Fix 12bpc HDMI enable for IBX

      Follow the procedure listed in Bspec to toggle the port enable bit off
      and on when enabling HDMI with 12bpc and pixel repeat on IBX. The old
      code didn't actually enable the port before "toggling" the bit back off,
      so the whole workaround was essentially a nop.

      Also take the opportunity to clarify the code by splitting the gmch
      platforms to a separate (much more straightforward) function.

      When the video timings are suitably aligned so that all different

      we can inform the sink about this. Supposedly the sink can then

      drm/i915: Send GCP infoframes for deep color HDMI sinks

      GCP infoframes are required to inform the HDMI sink about the color
      depth.

      Send the GCP infoframe whenever the sink supports any deep color modes
      since such sinks must anyway be capable of receiving them. For sinks
      that don't support deep color let's skip the GCP in case it might
      confuse the sink, although HDMI 1.4 spec does say all sinks must be
      capable of reciving them. In theory we could skip the GCP infoframe
      for deep color sinks in 8bpc mode as well since sinks must fall back to
      8bpc whenever GCP isn't received for some time.

      BSpec says we should disable GCP after disabling the port, so do that as
      well.

      The ADC is typically shared with remote CPUs not running Linux.
      However, there is only one register to power-up/power-down. Remote CPUs
      aren't able to power-up the ADC, and rely in Linux doing it instead.

      This commit uses the adc-reserved-channels devicetree property to
      distinguish shared usage. In this case, the ADC is powered up at
      probe time.

      If the ADC is used only by the CPU running Linux, power-up/down
      at runtime, only when neeeded.

      drm/i915: Do not use atomic modesets in hw readout.

      This should fix fallout caused by making intel_crtc_control
      and update_dpms atomic, which became a problem after reverting the
      atomic hw readout patch.

      Revert "drm/i915: Read hw state into an atomic state struct, v2."

      This reverts commit 3bae26eb2991c00670df377cf6c3bc2b0577e82a.

      Seems it introduces regressions for 3 different reasons, oh boy..

      In bug #90868 as I can see the atomic state will be restored on
      resume without the planes being set up properly. Because plane
      setup here requires the atomic state, we'll have to settle
      for committing atomic planes first.

      In bug #90861 the failure appears to affect mostly DP devices,
      and happens because reading out the atomic state prevents a modeset
      on boot, which would require better hw state readout.

      In bug #90874 it's shown that cdclk should be part of the atomic
      state, so only performing a single modeset during resume excarbated
      the issue.

      It's better to fix those issues first, and then commit this patch,
      so do that temporarily.

      This reverts commit 490f400db5d886fc28566af69b02f6497f31be4b.

      We're not ready yet to make it atomic, we calculate some state in
      advance, but without atomic plane support atomic the hw readout will
      fail.

      It's required to revert this commit to revert the atomic hw
      state readout patch.

      drm/i915: Use atomic state for calculating DVO_2X_MODE on i830.

      This is a small behavioral change because it leaves DVO_2X_MODE
      set between crtc_disable and crtc_enable. This is probably harmless
      though and if not should be fixed by calculating 2x mode before
      enable/disable pll.

      drm/i915: Calculate haswell plane workaround, v5.

      This needs to be done last after all modesets have been calculated.

      A modeset first disables all crtc's, so any crtc that undergoes a
      modeset counts as inactive.

      If no modeset's done, or > 1 crtc's stay w/a doesn't apply.
      Apply workaround on the first crtc if 1 crtc stays active.
      Apply workaround on the second crtc if no crtc was active.

      Changes since v1:
       - Use intel_crtc->atomic as a place to put hsw_workaround_pipe.
       - Make sure quirk only applies to haswell.
       - Use first loop to iterate over newly enabled crtc's only.
         This increases readability.
      Changes since v2:
       - Move hsw_workaround_pipe back to crtc_state.
      Changes since v3:
       - Return errors from haswell_mode_set_planes_workaround.
      Changes since v4:
      - Clean up commit message.

      This change had to be done after converting suspend/resume to
      use atomic_state so the atomic state is preserved, otherwise

      drm/i915: Read hw state into an atomic state struct, v2.

      To make this work we load the new hardware state into the
      atomic_state, then swap it with the sw state.

      This lets us change the force restore path in setup_hw_state()
      to use a single call to intel_mode_set() to restore all the
      previous state.

      As a nice bonus this kills off encoder->new_encoder,
      connector->new_enabled and crtc->new_enabled. They were used only
      to restore the state after a modeset.

      Changes since v1:
      - Make sure all possible planes are added with their crtc set,
        so they will be turned off on first modeset.

      Solve it by using the newly introduced 
drm_atomic_helper_commit_planes_on_crtc.

      The problem here was that the drm_atomic_helper_commit_planes() helper
      we were using was basically designed to do

          begin_crtc_commit(crtc #1)
          begin_crtc_commit(crtc #2)
          ...
          commit all planes
          finish_crtc_commit(crtc #1)
          finish_crtc_commit(crtc #2)

      The problem here is that since our hardware relies on vblank evasion,
      our CRTC 'begin' function waits until we're out of the danger zone in
      which register writes might wind up straddling the vblank, then disables
      interrupts; our 'finish' function re-enables interrupts after the
      registers have been written.  The expectation is that the operations 
between
      'begin' and 'end' must be performed without sleeping (since interrupts
      are disabled) and should happen as quickly as possible.  By clumping all
      of the 'begin' calls together, we introducing a couple problems:
       * Subsequent 'begin' invocations might sleep (which is illegal)
       * The first 'begin' ensured that we were far enough from the vblank that
         we could write our registers safely and ensure they all fell within
         the same frame.  Adding extra delay waiting for subsequent CRTC's
         wasn't accounted for and could put us back into the 'danger zone' for
         CRTC #1.

      This commit solves the problem by using a new helper that allows an
      order of operations like:

         for each crtc {
              begin_crtc_commit(crtc)  // sleep (maybe), then disable interrupts
              commit planes for this specific CRTC
              end_crtc_commit(crtc)    // reenable interrupts
         }

      so that sleeps will only be performed while interrupts are enabled and
      we can be sure that registers for a CRTC will be written immediately
      once we know we're in the safe zone.

      The crtc->config->base.crtc update may seem unrelated, but the helper
      will use it to obtain the crtc for the state. Without the update it
      will dereference NULL and crash.

      Changes since v1:
      - Use Matt Roper's commit message.

      drm/i915: Use crtc_state->active instead of crtc_state->enable

      crtc_state->enable means a crtc is configured, but it may be turned
      off for dpms. Until the commit "use intel_crtc_control everywhere"
      crtc_state->active was not updated on crtc off, but now
      crtc_state->active should be used for tracking whether a crtc is
      scanning out or not.

      A few commits from now dpms will be handled by calling
      intel_set_mode with a different value for crtc_state->active,
      which causes a crtc to turn on or off.

      At this point crtc->active should mirror crtc_state->active,
      so some paranoia from the crtc_disable functions can be removed.

      intel_set_mode_setup_plls still checks for ->enable, because all
      resources that are needed have to be calculated, else
      dpms changes may not succeed.

      drm/i915/bxt: fix DDI PHY vswing scale value setting

      According to bspec the DDI PHY vswing scale value is "don't care" in
      case the scale enable bit [27] is clear. But this doesn't seem to be
      correct. The scale value seems to also matter if the scale mode bit
      [26] is set. So both bit 26 and 27 depend on the value. Setting the
      scale value to 0 while either bit is set results in a failed modeset on
      HDMI (sink reports no signal).

      After reset the scale value is 0x98, but according to the spec we have
      to program it to 0x9a. So for consistency program it always to 0x9a
      regardless of the scale enable bit.

      drm/i915: Don't enable IPS when pixel rate exceeds 95%

      Bspec says we shouldn't enable IPS on BDW when the pipe pixel rate
      exceeds 95% of the core display clock. Apparently this can cause
      underruns.

      There's no similar restriction listed for HSW, so leave that one alone
      for now.

      Keep the cdclk maximum supported frequency around in dev_priv so that we

      For now only VLV/CHV have support changing cdclk frequency, so other

      clk: ti: move interface clock implementation under drivers/clk

      With the legacy clock support gone, the OMAP interface clock 
implementation
      can be moved under the clock driver. Some temporary header file tweaks are
      also needed to make this change work properly.

      As most of the clock driver support code is going to be moved under
      drivers/clk/ti, an API for setting / getting the SoC specific clock
      features is needed. This patch provides this API and changes the
      existing code to use it.

      The hotplug status is cached in hp_control, and will be passed on to

      So far I've tested this on one ELK where it gave me a HPLL VCO of 5333

      drm/i915: add a context parameter to {en, dis}able zero address mapping

      Export a new context parameter that can be set/queried through the
      context_{get,set}param ioctls.  This parameter is passed as a context
      flag and decides whether or not a GPU address mapping is allowed to
      be made at address zero.  The default is to allow such mappings.

      deb-pkg: Add device tree blobs to the package

      When building a package with make deb-pkg (say, for arm), the dtb files 
are
      not added to the package. Given that things are still evolving on arm, it
      make sense to have them along with the kernel and modules.

      builddeb: fix stripped module signatures if CONFIG_DEBUG_INFO and 
CONFIG_MODULE_SIG_ALL are set

      If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are
      automatically signed in the result package, as it's for rpm-pkg, 
binrpm-pkg,
      tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO
      is NOT set. In that case deb-package contains signed modules.

      But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with
      debug information. To do that, debug information from all modules
      is copied into separate files by objcopy. And loadable kernel modules are
      stripped afterwards. Stripping removes previously (during modules_install)
      added signatures from loadable kernel modules. Therefore final deb-package
      contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL.

      This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set
      to solve this problem.

      deb-pkg: move setting debarch for a separate function

      create_package() function tries to resolve used architecture
      for everry package. Split the setting the architecture to a
      new function, set_debarch(), called once on startup.

      This allows using debarch from other parts of script as
      needed.

      v2: Follow Michals suggestion on setting variables at
      top scope and also setting the fallback $debarch in the
      new function

      KVM: disable halt_poll_ns as default for s390x

      We observed some performance degradation on s390x with dynamic
      halt polling. Until we can provide a proper fix, let's enable
      halt_poll_ns as default only for supported architectures.

      Architectures are now free to set their own halt_poll_ns
      default value.

      KVM: x86: fix off-by-one in reserved bits check

      29ecd6601904 ("KVM: x86: avoid uninitialized variable warning",
      2015-09-06) introduced a not-so-subtle problem, which probably
      escaped review because it was not part of the patch context.

      Before the patch, leaf was always equal to iterator.level.  After,
      it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set,
      and when is_shadow_zero_bits_set does another "-1" the check on
      reserved bits becomes incorrect.  Using "iterator.level" in the call
      fixes this call trace:

      KVM: x86: use correct page table format to check nested page table 
reserved bits

      Intel CPUID on AMD host or vice versa is a weird case, but it can
      happen.  Handle it by checking the host CPU vendor instead of the
      guest's in reset_tdp_shadow_zero_bits_mask.  For speed, the
      check uses the fact that Intel EPT has an X (executable) bit while
      AMD NPT has NX.

      KVM: svm: do not call kvm_set_cr0 from init_vmcb

      kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the
      memslots array (SRCU protected).  Using a mini SRCU critical section
      is ugly, and adding it to kvm_arch_vcpu_create doesn't work because
      the VMX vcpu_create callback calls synchronize_srcu.

      Documentation: arm: Fix typo in the idle-states bindings examples

      The idle-states bindings mandate that the entry-method string
      in the idle-states node must be "psci" for ARM v8 64-bit systems,
      but the examples in the bindings report a wrong entry-method string.
      Owing to this typo, some dts in the kernel wrongly defined the
      entry-method property, since they likely cut and pasted the example
      definition without paying attention to the bindings definitions.

      This patch fixes the typo in the DT idle states bindings examples and
      respective dts in the kernel so that the bindings and related dts
      files are made compliant.

      gpio: mention in DT binding doc that <name>-gpio is deprecated

      The gpiolib supports parsing DT properties of the form <name>-gpio but it
      was only added for compatibility with older DT bindings that got it wrong
      and should not be used in newer bindings.

      The commit that added support for this was:

      dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names")

      but didn't update the documentation to explain this so it's been a source
      of confusion. So let's make this clear in the GPIO DT binding doc.

      PCI: Use function 0 VPD for identical functions, regular VPD for others

      932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0")
      added PCI_DEV_FLAGS_VPD_REF_F0.  Previously, we set the flag on every
      non-zero function of quirked devices.  If a function turned out to be
      different from function 0, i.e., it had a different class, vendor ID, or
      device ID, the flag remained set but we didn't make VPD accessible at all.

      Flip this around so we only set PCI_DEV_FLAGS_VPD_REF_F0 for functions 
that
      are identical to function 0, and allow regular VPD access for any other
      functions.

      PCI: Fix devfn for VPD access through function 0

      Commit 932c435caba8 ("PCI: Add dev_flags bit to access VPD through 
function
      0") passes PCI_SLOT(devfn) for the devfn parameter of pci_get_slot().
      Generally this works because we're fairly well guaranteed that a PCIe
      device is at slot address 0, but for the general case, including
      conventional PCI, it's incorrect.  We need to get the slot and then 
convert
      it back into a devfn.

      PCI/MSI: Fix MSI IRQ domains for VFs on virtual buses

      SR-IOV creates a virtual bus where bus->self is NULL.  When we add VFs and
      scan for an MSI domain, pci_set_bus_msi_domain() dereferences bus->self,
      which causes a kernel NULL pointer dereference oops.

      Scan up to the parent bus until we find a real bridge where we can get the
      MSI domain.

      ALSA: hda - Disable power_save_node for Thinkpads

      Lenovo Thinkpads with recent Realtek codecs seem suffering from click
      noises at power transition since the introduction of widget power
      saving in 4.1 kernel.  Although this might be solved by some delays in
      appropriate points, as a quick workaround, just disable the
      power_save_node feature for now.  The gain it gives is relatively
      small, and this makes the situation back to pre 4.1 time.

      This patch ended up with a bit more code changes than usual because
      the existing fixup for Thinkpads is highly chained.  Instead of adding
      yet another chain, combine a few of them into a single fixup entry, as
      a gratis cleanup.

      ALSA: hda/tegra - async probe for avoiding module loading deadlock

      The Tegra HD-audio controller driver causes deadlocks when loaded as a
      module since the driver invokes request_module() at binding with the
      codec driver.  This patch works around it by deferring the probe in a
      work like Intel HD-audio controller driver does.  Although hovering
      the codec probe stuff into udev would be a better solution, it may
      cause other regressions, so let's try this band-aid fix until the more
      proper solution gets landed.

      drm: Allow also control clients to check the drm version

      This should be harmless.
      Vmware will, due to old infrastructure reasons, be using a privileged
      control client to supply GUI layout information rather than obtaining
      it from the device. That control client will be needing access to DRM
      version information.

      drm/mgag200: Fix driver_load error handling

      mgag200_driver_load's error path just calls the drm driver's
      driver_unload op. It isn't safe to call this because it doesn't handle
      things well if driver_load fails somewhere mid way.

      Replace the call to mgag200_driver_unload with a more finegrained
      error handling path.

      drm/amdgpu: sync ce and me with SWITCH_BUFFER(2)

      we used to adopt wait_reg_mem to let CE wait before DE finish page
      updating, but from Tonga+, CE doesn't support wait_reg_mem package so
      this logic no longer works.

      so here is another approach to do same thing:
      Insert two of SWITCH_BUFFER at both front and end of vm_flush can
      guarantee that CE not go further to process IB_const before vm_flush
      done.

      Insert two of SWITCH_BUFFER also works on CI, so remove legency method
      to sync CE and ME

      v2:
      Insert double SWITCH_BUFFER at front of vm flush as well.

      drm/amdgpu: unwind properly in amdgpu_cs_parser_init()

      The amdgpu_cs_parser_init() function doesn't clean up after itself but
      instead the caller uses a free everything function amdgpu_cs_parser_fini()
      on failure.  This style of error handling is often buggy.  In this
      example, we call "drm_free_large(parser->chunks[i].kdata);" when it is
      an unintialized pointer or when "parser->chunks" is NULL.

      I fixed this bug by adding unwind code so that it frees everything that
      it allocates.

      I also mode some other very minor changes:
      1) Renamed "r" to "ret".
      2) Moved the chunk_array allocation to the start of the function.
      3) Removed some initializers which are no longer needed.

      drm/i915/bios: handle MIPI Sequence Block v3+ gracefully

      The VBT MIPI Sequence Block version 3 has forward incompatible changes:

      First, the block size in the header has been specified reserved, and the
      actual size is a separate 32-bit value within the block. The current
      find_section() function to will only look at the size in the block
      header, and, depending on what's in that now reserved size field,
      continue looking for other sections in the wrong place.

      Fix this by taking the new block size field into account. This will
      ensure that the lookups for other sections will work properly, as long
      as the new 32-bit size does not go beyond the opregion VBT mailbox size.

      Second, the contents of the block have been completely
      changed. Gracefully refuse parsing the yet unknown data version.

      cxl: Fix lockdep warning while creating afu_err_buff attribute

      Presently a lockdep warning is reported during creation of afu_err_buff
      bin_attribute for the afu. This is caused due to the variable attr.key
      not pointing to a static class key, hence the function lockdep_init_map
      reports this warning:

       BUG: key <some-address> not in .data!

      The patch fixes this issue by calling sysfs_attr_init on the
      attr_eb.attr structure before populating it with the afu_err_buff file
      details. This will populate the attr.key variable with a static class
      key so that lockdep_init_map stops complaining about the lockdep key not
      being static.

      drm/i915: workaround bad DSL readout v3

      On HSW at least (still testing other platforms, but should be harmless
      elsewhere), the DSL reg reads back as 0 when read around vblank start
      time.  This ends up confusing the atomic start/end checking code, since
      it causes the update to appear as if it crossed a frame count boundary.
      Avoid the problem by making sure we don't return scanline_offset from
      the get_crtc_scanline function.  In moving the code there, I add to add
      an additional delay since it could be called and have a legitimate 0
      result for some time (depending on the pixel clock).

      v3: use break instead of goto (Ville)

      ocfs2/dlm: fix deadlock when dispatch assert master

      The order of the following three spinlocks should be:
      dlm_domain_lock < dlm_ctxt->spinlock < dlm_lock_resource->spinlock

      But dlm_dispatch_assert_master() is called while holding
      dlm_ctxt->spinlock and dlm_lock_resource->spinlock, and then it calls
      dlm_grab() which will take dlm_domain_lock.

      Once another thread (for example, dlm_query_join_handler) has already
      taken dlm_domain_lock, and tries to take dlm_ctxt->spinlock deadlock
      happens.

      x86, efi, kasan: #undef memset/memcpy/memmove per arch

      In not-instrumented code KASAN replaces instrumented memset/memcpy/memmove
      with not-instrumented analogues __memset/__memcpy/__memove.

      However, on x86 the EFI stub is not linked with the kernel.  It uses
      not-instrumented mem*() functions from arch/x86/boot/compressed/string.c

      So we don't replace them with __mem*() variants in EFI stub.

      On ARM64 the EFI stub is linked with the kernel, so we should replace
      mem*() functions with __mem*(), because the EFI stub runs before KASAN
      sets up early shadow.

      So let's move these #undef mem* into arch's asm/efi.h which is also
      included by the EFI stub.

      Also, this will fix the warning in 32-bit build reported by kbuild test
      robot:

        efi-stub-helper.c:599:2: warning: implicit declaration of function

      mm: migrate: hugetlb: putback destination hugepage to active list

      Since commit bcc54222309c ("mm: hugetlb: introduce page_huge_active")
      each hugetlb page maintains its active flag to avoid a race condition
      betwe= en multiple calls of isolate_huge_page(), but current kernel
      doesn't set the f= lag on a hugepage allocated by migration because the
      proper putback routine isn= 't called.  This means that users could
      still encounter the race referred to by bcc54222309c in this special
      case, so this patch fixes it.

      mm, dax: VMA with vm_ops->pfn_mkwrite wants to be write-notified

      For VM_PFNMAP and VM_MIXEDMAP we use vm_ops->pfn_mkwrite instead of
      vm_ops->page_mkwrite to notify abort write access.  This means we want
      vma->vm_page_prot to be write-protected if the VMA provides this vm_ops.

      A theoretical scenario that will cause these missed events is:

        On writable mapping with vm_ops->pfn_mkwrite, but without
        vm_ops->page_mkwrite: read fault followed by write access to the pfn.
        Writable pte will be set up on read fault and write fault will not be
        generated.

      I found it examining Dave's complaint on generic/080:

        http://lkml.kernel.org/g/20150831233803.GO3902@dastard

      Although I don't think it's the reason.

      It shouldn't be a problem for ext2/ext4 as they provide both pfn_mkwrite
      and page_mkwrite.

      userfaultfd: revert "userfaultfd: waitqueue: add nr wake parameter to 
__wake_up_locked_key"

      This reverts commit 51360155eccb907ff8635bd10fc7de876408c2e0 and adapts
      fs/userfaultfd.c to use the old version of that function.

      It didn't look robust to call __wake_up_common with "nr == 1" when we
      absolutely require wakeall semantics, but we've full control of what we
      insert in the two waitqueue heads of the blocked userfaults.  No
      exclusive waitqueue risks to be inserted into those two waitqueue heads
      so we can as well stick to "nr == 1" of the old code and we can rely
      purely on the fact no waitqueue inserted in one of the two waitqueue
      heads we must enforce as wakeall, has wait->flags WQ_FLAG_EXCLUSIVE set.

      PCI: Clear IORESOURCE_UNSET when clipping a bridge window

      c770cb4cb505 ("PCI: Mark invalid BARs as unassigned") sets 
IORESOURCE_UNSET
      if we fail to claim a resource.  If we tried to claim a bridge window,
      failed, clipped the window, and tried to claim the clipped window, we
      failed again because of IORESOURCE_UNSET:

        pci_bus 0000:00: root bus resource [mem 0xc0000000-0xffffffff window]
        pci 0000:00:01.0: can't claim BAR 15 [mem 0xbdf00000-0xddefffff 64bit 
pref]: no compatible bridge window
        pci 0000:00:01.0: [mem size 0x20000000 64bit pref] clipped to [mem size 
0x1df00000 64bit pref]
        pci 0000:00:01.0:   bridge window [mem size 0x1df00000 64bit pref]
        pci 0000:00:01.0: can't claim BAR 15 [mem size 0x1df00000 64bit pref]: 
no address assigned

      The 00:01.0 window started as [mem 0xbdf00000-0xddefffff 64bit pref].  
That
      starts before the host bridge window [mem 0xc0000000-0xffffffff window], 
so
      we clipped the 00:01.0 window to [mem 0xc0000000-0xddefffff 64bit pref].
      But we left it marked IORESOURCE_UNSET, so the second claim failed when it
      should have succeeded.

      This means downstream devices will also fail for lack of resources, e.g.,
      in the bugzilla below,

        radeon 0000:01:00.0: Fatal error during GPU init

      Clear IORESOURCE_UNSET when we clip a bridge window.  Also clear
      IORESOURCE_UNSET in our copy of the unclipped window so we can see exactly
      what the original window was and how it now fits inside the upstream
      window.

      Btrfs: keep dropped roots in cache until transaction commit

      When dropping a snapshot we need to account for the qgroup changes.  If 
we drop
      the snapshot in all one go then the backref code will fail to find blocks 
from
      the snapshot we dropped since it won't be able to find the root in the fs 
root
      cache.  This can lead to us failing to find refs from other roots that 
pointed
      at blocks in the now deleted root.  To handle this we need to not remove 
the fs
      roots from the cache until after we process the qgroup operations.  Do 
this by
      adding dropped roots to a list on the transaction, and letting the 
transaction
      remove the roots at the same time it drops the commit roots.  This will 
keep all
      of the backref searching code in sync properly, and fixes a problem Mark 
was
      seeing with snapshot delete and qgroups.  Thanks,

      MAINTAINERS: Update website and git repo for Wolfson Microelectronics

      Support for Wolfson Microelectronics devices is now part of Cirrus Logic
      and the relevant parts of the old opensource.wolfsonmicro.com site have
      moved to the Cirrus Logic GitHub area.

      This patch updates the website and git repo links, and also removes an
      obsolete website link for the voltage and current drivers.

      Pull cgroup fixes from Tejun Heo:
       "The threadgroup locking changes which went in during 4.2 devel cycle
        added write locking of a percpu_rwsem in cgroup task migration path;
        unfortunately, that involved expedited rcu syncing which turned out to
        be too slow and heavy for certain workloads.  The patchset which is
        dependent on this one didn't get committed during that devel cycle, so
        these two patches can be reverted safely.

        Oleg reworked percpu_rwsem for 4.4 so that the writer path is a lot
        lighter.  The reported issue goes away with Oleg's reworked
        percpu_rwsem and I'll reapply these patches on the for-4.4 branch so
        that they can land together with Oleg's changes"

      This means that the inode had non-zero "outstanding extents" during
      eviction. This occurs because, during direct I/O a task which successfully
      used up its reserved data space would set BTRFS_INODE_DIO_READY bit and 
does
      not clear the bit after finishing the DIO write. A future DIO write could
      actually fail and the unused reserve space won't be freed because of the
      previously set BTRFS_INODE_DIO_READY bit.

      Clearing the BTRFS_INODE_DIO_READY bit in btrfs_direct_IO() caused the
      following issue,

      Hence this commit introduces "struct btrfs_dio_data" to track the usage of
      reserved data space. The remaining unused "reserve space" can now be freed
      reliably.

      These have roughly the same purpose as the SMRR, which we do not need
      to implement in KVM.  However, Linux accesses MSR_K8_TSEG_ADDR at
      boot, which causes problems when running a Xen dom0 under KVM.

      NFSv4: Recovery of recalled read delegations is broken

      When a read delegation is being recalled, and we're reclaiming the
      cached opens, we need to make sure that we only reclaim read-only
      modes.
      A previous attempt to do this, relied on retrieving the delegation
      type from the nfs4_opendata structure. Unfortunately, as Kinglong
      pointed out, this field can only be set when performing reboot recovery.

      Furthermore, if we call nfs4_open_recover(), then we end up clobbering
      the state->flags for all modes that we're not recovering...

      The fix is to have the delegation recall code pass this information
      to the recovery call, and then refactor the recovery code so that
      nfs4_open_delegation_recall() does not need to call nfs4_open_recover().

kvmppc_h_logical_ci_load/store()

      Access to the kvm->buses (like with the kvm_io_bus_read() and -write()
      functions) has to be protected via the kvm->srcu lock.
      The kvmppc_h_logical_ci_load() and -store() functions are missing
      this lock so far, so let's add it there, too.
      This fixes the problem that the kernel reports "suspicious RCU usage"

      KVM: PPC: Book3S HV: Pass the correct trap argument to kvmhv_commence_exit

      In guest_exit_cont we call kvmhv_commence_exit which expects the trap
      number as the argument. However r3 doesn't contain the trap number at
      this point and as a result we would be calling the function with a
      spurious trap number.

      Fix this by copying r12 into r3 before calling kvmhv_commence_exit as
      r12 contains the trap number.

      KVM: PPC: Book3S HV: Fix handling of interrupted VCPUs

      This fixes a bug which results in stale vcore pointers being left in
      the per-cpu preempted vcore lists when a VM is destroyed.  The result
      of the stale vcore pointers is usually either a crash or a lockup
      inside collect_piggybacks() when another VM is run.  A typical
      lockup message looks like:

      The bug is that kvmppc_run_vcpu does not correctly handle the case
      where a vcpu task receives a signal while its guest vcpu is executing
      in the guest as a result of being piggy-backed onto the execution of
      another vcore.  In that case we need to wait for the vcpu to finish
      executing inside the guest, and then remove this vcore from the
      preempted vcores list.  That way, we avoid leaving this vcpu's vcore
      on the preempted vcores list when the vcpu gets interrupted.

      NFS: Fix an infinite loop when layoutget fail with BAD_STATEID

      If layouget fail with BAD_STATEID, restart should not using the old 
stateid.
      But, nfs client choose the layout stateid at first, and then the open 
stateid.

      To avoid the infinite loop of using bad stateid for layoutget,
      this patch sets the layout flag'ss NFS_LAYOUT_INVALID_STID bit to
      skip choosing the bad layout stateid.

      thermal: power_allocator: exit early if there are no cooling devices

      Don't waste cycles in the power allocator governor's throttle function
      if there are no cooling devices and exit early.

      This commit doesn't change any functionality, but should provide better
      performance for the odd case of a thermal zone with trip points but
      without cooling devices.

      fs-writeback: unplug before cond_resched in writeback_sb_inodes

      Commit 505a666ee3fc ("writeback: plug writeback in wb_writeback() and
      writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes,
      which increases the merge rate when relatively contiguous small files
      are written by the filesystem.  It helps both on flash and spindles.

      For an fs_mark workload creating 4K files in parallel across 8 drives,
      this commit improves performance ~9% more by unplugging before calling
      cond_resched().  cond_resched() doesn't trigger an implicit unplug, so
      explicitly getting the IO down to the device before scheduling reduces
      latencies for anyone waiting on clean pages.

      It also cuts down on how often we use kblockd to unplug, which means
      less work bouncing from one workqueue to another.

      Many more details about how we got here:

      ASoC: fsl_ssi: Fix checking of dai format for AC97 mode

      Current code incorrectly treats dai format for AC97 as bit mask
      whereas it's actually an integer value. This causes DAI formats
      other than AC97 (e.g. DSP_B) to trigger AC97 related code,
      which is incorrect and breaks functionality. This patch fixes
      the code to correctly compare values to determine AC97 or not.

      mm: fix type cast in __pfn_to_phys()

      The various definitions of __pfn_to_phys() have been consolidated to
      use a generic macro in include/asm-generic/memory_model.h. This hit
      mainline in the form of 012dcef3f058 "mm: move __phys_to_pfn and
      __pfn_to_phys to asm/generic/memory_model.h". When the generic macro
      was implemented the type cast to phys_addr_t was dropped which caused
      boot regressions on ARM platforms with more than 4GB of memory and
      LPAE enabled.

      It was suggested to use PFN_PHYS() defined in include/linux/pfn.h
      as provides the correct logic and avoids further duplication.

      IB/hfi: Properly set permissions for user device files

      Some of the device files are required to be user accessible for PSM while
      most should remain accessible only by root.

      Add a parameter to hfi1_cdev_init which controls if the user should have 
access
      to this device which places it in a different class with the appropriate
      devnode callback.

      In addition set the devnode call back for the existing class to be a bit 
more
      explicit for those permissions.

      Finally remove the unnecessary null check before class_destroy

         - Final removal of ARM artifacts which had been introduced during the
           conversion of ARM to the generic interrupt code.

         - Final split of the irq_data into chip specific and common data to
           reflect the needs of hierarchical irq domains.

         - Treewide removal of the first argument of interrupt flow handlers,
           i.e. the irq number, which is not used by the majority of handlers
           and simple to retrieve from the other argument the irq descriptor.

      kvm: svm: reset mmu on VCPU reset

      When INIT/SIPI sequence is sent to VCPU which before that
      was in use by OS, VMRUN might fail with:

       KVM: entry failed, hardware error 0xffffffff

       [...]
       EFER=0000000000000000

      with corresponding SVM error:
       KVM: FAILED VMRUN WITH VMCB:
       [...]
       cpl:            0                efer:         0000000000001000

       [...]

      What happens is that VCPU state right after offlinig:
      CR0: 0x80050033  EFER: 0xd01  CR4: 0x7e0
        -> long mode with CR3 pointing to longmode page tables

      and when VCPU gets INIT/SIPI following transition happens
      CR0: 0 -> 0x60000010 EFER: 0x0  CR4: 0x7e0
        -> paging disabled with stale CR3

      However SVM under the hood puts VCPU in Paged Real Mode*
      which effectively translates CR0 0x60000010 -> 80010010 after

         svm_vcpu_reset()
             -> init_vmcb()
                 -> kvm_set_cr0()
                     -> svm_set_cr0()

      but from  kvm_set_cr0() perspective CR0: 0 -> 0x60000010
      only caching bits are changed and
      commit d81135a57aa6
       ("KVM: x86: do not reset mmu if CR0.CD and CR0.NW are changed")'
      regressed svm_vcpu_reset() which relied on MMU being reset.

      As result VMRUN after svm_vcpu_reset() tries to run
      VCPU in Paged Real Mode with stale MMU context (longmode page tables),
      which causes some AMD CPUs** to bail out with VMEXIT_INVALID.

      Fix issue by unconditionally resetting MMU context
      at init_vmcb() time.

      sched: access local runqueue directly in single_task_running

      Commit 2ee507c47293 ("sched: Add function single_task_running to let a 
task
      check if it is the only task running on a cpu") referenced the current
      runqueue with the smp_processor_id.  When CONFIG_DEBUG_PREEMPT is enabled,
      that is only allowed if preemption is disabled or the currrent task is
      bound to the local cpu (e.g. kernel worker).

      With commit f78195129963 ("kvm: add halt_poll_ns module parameter") KVM
      calls single_task_running. If CONFIG_DEBUG_PREEMPT is enabled that
      generates a lot of kernel messages.

      To avoid adding preemption in that cases, as it would limit the 
usefulness,
      we change single_task_running to access directly the cpu local runqueue.

      s390: wire up separate socketcalls system calls

      As discussed on linux-arch all architectures should wire up the separate
      system calls that are hidden behind the socketcall multiplexer system 
call.

      It's just a couple more system calls and gives us a very small performance
      improvement.

      s390/compat: remove superfluous compat wrappers

      A couple of compat wrapper functions are simply trampolines to the real
      system call. This happened because the compat wrapper defines will only
      sign and zero extend system call parameters which are of different size
      on s390/s390x (longs and pointers).
      All other parameters will be correctly sign and zero extended by the
      normal system call wrappers.

      lib/string_helpers.c: fix infinite loop in string_get_size()

      Some string_get_size() calls (e.g.:
       string_get_size(1, 512, STRING_UNITS_10, ..., ...)
       string_get_size(15, 64, STRING_UNITS_10, ..., ...)
      ) result in an infinite loop. The problem is that if size is equal to
      divisor[units]/blk_size and is smaller than divisor[units] we'll end
      up with size == 0 when we start doing sf_cap calculations:

      For string_get_size(1, 512, STRING_UNITS_10, ..., ...) case:
         ...
         remainder = do_div(size, divisor[units]); -> size is 0, remainder is 1
         remainder *= blk_size; -> remainder is 512
         ...
         size *= blk_size; -> size is still 0
         size += remainder / divisor[units]; -> size is still 0

      The caller causing the issue is sd_read_capacity(), the problem was
      noticed on Hyper-V, such weird size was reported by host when scanning
      collides with device removal.  This is probably a separate issue worth
      fixing, this patch is intended to prevent the library routine from
      infinite looping.

      kasan: fix last shadow judgement in memory_is_poisoned_16()

      The shadow which correspond 16 bytes memory may span 2 or 3 bytes.  If
      the memory is aligned on 8, then the shadow takes only 2 bytes.  So we
      check "shadow_first_bytes" is enough, and need not to call
      "memory_is_poisoned_1(addr + 15);".  But the code "if
      (likely(!last_byte))" is wrong judgement.

      e.g.  addr=0, so last_byte = 15 & KASAN_SHADOW_MASK = 7, then the code
      will continue to call "memory_is_poisoned_1(addr + 15);"

      zram: fix possible use after free in zcomp_create()

      zcomp_create() verifies the success of zcomp_strm_{multi,single}_create()
      through comp->stream, which can potentially be pointing to memory that
      was freed if these functions returned an error.

      While at it, replace a 'ERR_PTR(-ENOMEM)' by a more generic
      'ERR_PTR(error)' as in the future zcomp_strm_{multi,siggle}_create()
      could return other error codes.  Function documentation updated
      accordingly.

      hp-wmi: limit hotkey enable

      Do not write initialize magic on systems that do not have
      feature query 0xb. Fixes Bug #82451.

      Redefine FEATURE_QUERY to align with 0xb and FEATURE2 with 0xd
      for code clearity.

      Add a new test function, hp_wmi_bios_2008_later() & simplify
      hp_wmi_bios_2009_later(), which fixes a bug in cases where
      an improper value is returned. Probably also fixes Bug #69131.

      Add missing __init tag.

      SUNRPC: Ensure that we wait for connections to complete before retrying

      Commit 718ba5b87343, moved the responsibility for unlocking the socket to
      xs_tcp_setup_socket, meaning that the socket will be unlocked before we
      know that it has finished trying to connect. The following patch is based 
on
      an initial patch by Russell King to ensure that we delay clearing the
      XPRT_CONNECTING flag until we either know that we failed to initiate
      a connection attempt, or the connection attempt itself failed.

      Failing to send a CLOSE if file is opened WRONLY and server reboots on a 
4.x mount

      A test case is as the description says:
      open(foobar, O_WRONLY);
      sleep()  --> reboot the server
      close(foobar)

      The bug is because in nfs4state.c in nfs4_reclaim_open_state() a few
      line before going to restart, there is
      clear_bit(NFS4CLNT_RECLAIM_NOGRACE, &state->flags).

      NFS4CLNT_RECLAIM_NOGRACE is a flag for the client states not open
      owner states. Value of NFS4CLNT_RECLAIM_NOGRACE is 4 which is the
      value of NFS_O_WRONLY_STATE in nfs4_state->flags. So clearing it wipes
      out state and when we go to close it, â??call_closeâ?? doesnâ??t get set 
as
      state flag is not set and CLOSE doesnâ??t go on the wire.

      of_pci_irq: Silence bogus "of_irq_parse_pci() failed ..." messages.

      It is perfectly legitimate for a PCI device to have an
      PCI_INTERRUPT_PIN value of zero.  This happens if the device doesn't
      use interrupts, or on PCIe devices, where only MSI/MSI-X are
      supported.

      Silence the annoying "of_irq_parse_pci() failed with rc=-19" error
      messages by moving the printing code into of_irq_parse_pci(), and only
      emitting the message for cases where PCI_INTERRUPT_PIN == 0 is not the

      devicetree: bindings: Extend the bma180 bindings with bma250 info

      The bma180 / bma250 accelerometers share a driver (at least under Linux),
      so it makes sense to also have their bindings info in a single .txt.

      This commit extends the bma180 bindings with bma250 bindings, specifically
      it specifies how the 2 seperate interrupts the bma250 has must be listed
      in devicetree. The existing bma180 driver is already fully compatible
      with the specified bindings.

      valid error code if regulator_dev_lookup returned NULL. Currently
      regulator_resolve_supply checks this ret value before it checks if a

      block: fix bounce_end_io

      When bio bounce is involved, one new bio and its biovecs are
      cloned from the comming bio, which can be one fast-cloned bio
      from upper layer(such as dm).

      So it is obviously wrong to assume the start index of the coming(
      original) bio's io vector is zero, which can be any value between
      0 and (bi_max_vecs - 1), especially in case of bio split.

      This patch fixes Fedora's booting oops on i386, often with the
      following kernel log together:

      block: blk-merge: fast-clone bio when splitting rw bios

      biovecs has become immutable since v3.13, so it isn't necessary
      to allocate biovecs for the new cloned bios, then we can save
      one extra biovecs allocation/copy, and the allocation is often
      not fixed-length and a bit more expensive.

      For example, if the 'max_sectors_kb' of null blk's queue is set
      as 16(32 sectors) via sysfs just for making more splits, this patch
      can increase throught about ~70% in the sequential read test over
      null_blk(direct io, bs: 1M).

      arm/arm64: KVM: Remove 'config KVM_ARM_MAX_VCPUS'

      This patch removes config option of KVM_ARM_MAX_VCPUS,
      and like other ARCHs, just choose the maximum allowed
      value from hardware, and follows the reasons:

      1) from distribution view, the option has to be
      defined as the max allowed value because it need to
      meet all kinds of virtulization applications and
      need to support most of SoCs;

      2) using a bigger value doesn't introduce extra memory
      consumption, and the help text in Kconfig isn't accurate
      because kvm_vpu structure isn't allocated until request
      of creating VCPU is sent from QEMU;

      3) the main effect is that the field of vcpus[] in 'struct kvm'
      becomes a bit bigger(sizeof(void *) per vcpu) and need more cache
      lines to hold the structure, but 'struct kvm' is one generic struct,
      and it has worked well on other ARCHs already in this way. Also,
      the world switch frequecy is often low, for example, it is ~2000
      when running kernel building load in VM from APM xgene KVM host,
      so the effect is very small, and the difference can't be observed
      in my test at all.

      the kernel, it is much better to kill these (non existent) registers
      as soon as possible.

      arm: KVM: Disable virtual timer even if the guest is not using it

      When running a guest with the architected timer disabled (with QEMU and
      the kernel_irqchip=off option, for example), it is important to make
      sure the timer gets turned off. Otherwise, the guest may try to
      enable it anyway, leading to a screaming HW interrupt.

      The fix is to unconditionally turn off the virtual timer on guest
      exit.

      s390/vtime: correct scaled cputime for SMT

      The scaled cputime is supposed to be derived from the normal per-thread
      cputime by dividing it with the average thread density in the last 
interval.

      The calculation of the scaling values for the average thread density is
      incorrect. The current, incorrect calculation:

          Ci = cycle count with i active threads
          T = unscaled cputime, sT = scaled cputime
          sT = T * (C1 + C2 + ... + Cn) / (1*C1 + 2*C2 + ... + n*Cn)

      The calculation happens to yield the correct numbers for the simple cases
      with only one Ci value not zero. But for cases with multiple Ci values not
      zero it fails. E.g. on a SMT-2 system with one thread active half the time
      and two threads active for the other half of the time it fails, the 
scaling
      factor should be 3/4 but the formula gives 2/3.

      The correct formula is

          sT = T * (C1/1 + C2/2 + ... + Cn/n) / (C1 + C2 + ... + Cn)

      s390/compat: correct uc_sigmask of the compat signal frame

      The uc_sigmask in the ucontext structure is an array of words to keep
      the 64 signal bits (or 1024 if you ask glibc but the kernel sigset_t
      only has 64 bits).

      For 64 bit the sigset_t contains a single 8 byte word, but for 31 bit
      there are two 4 byte words. The compat signal handler code uses a
      simple copy of the 64 bit sigset_t to the 31 bit compat_sigset_t.
      As s390 is a big-endian architecture this is incorrect, the two words
      in the 31 bit sigset_t array need to be swapped.

      arm64: errata: add module build workaround for erratum #843419

      Cortex-A53 processors <= r0p4 are affected by erratum #843419 which can
      lead to a memory access using an incorrect address in certain sequences
      headed by an ADRP instruction.

      There is a linker fix to generate veneers for ADRP instructions, but
      this doesn't work for kernel modules which are built as unlinked ELF
      objects.

      This patch adds a new config option for the erratum which, when enabled,
      builds kernel modules with the mcmodel=large flag. This uses absolute
      addressing for all kernel symbols, thereby removing the use of ADRP as
      a PC-relative form of addressing. The ADRP relocs are removed from the
      module loader so that we fail to load any potentially affected modules.

      arm64: compat: fix vfp save/restore across signal handlers in big-endian

      When saving/restoring the VFP registers from a compat (AArch32)
      signal frame, we rely on the compat registers forming a prefix of the
      native register file and therefore make use of copy_{to,from}_user to
      transfer between the native fpsimd_state and the compat_vfp_sigframe.

      Unfortunately, this doesn't work so well in a big-endian environment.
      Our fpsimd save/restore code operates directly on 128-bit quantities
      (Q registers) whereas the compat_vfp_sigframe represents the registers
      as an array of 64-bit (D) registers. The architecture packs the compat D
      registers into the Q registers, with the least significant bytes holding
      the lower register. Consequently, we need to swap the 64-bit halves when
      converting between these two representations on a big-endian machine.

      This patch replaces the __copy_{to,from}_user invocations in our
      compat VFP signal handling code with explicit __put_user loops that
      operate on 64-bit values and swap them accordingly.

      leds:lp55xx: Correct Kconfig dependency for f/w user helper

      The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
      tries to address the firmware file handling with user helper, but it
      sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK.  Since the
      wrong option was enabled, the system got a regression -- it suffers
      from the unexpected long delays for non-present firmware files.

      This patch corrects the Kconfig dependency to the right one,
      CONFIG_FW_LOADER_USER_HELPER.  This doesn't change the fallback
      behavior but only enables UMH when needed.

      ARM: 8437/1: dma-mapping: fix build warning with new DMA_ERROR_CODE 
definition

      Commit 96231b2686b5: ("ARM: 8419/1: dma-mapping: harmonize definition
      of DMA_ERROR_CODE") changed the definition of DMA_ERROR_CODE to use
      dma_addr_t, which makes the compiler barf on assigning this to an
      "int" variable on ARM with LPAE enabled:

      Remove the #if statement which caused trouble for kernels that support

      clk: check for invalid parent index of orphans in __clk_init()

      If a mux clock is initialised (by hardware or firmware) with an
      invalid parent, its ->get_parent() can return an out of range
      index.  For example, the generic mux clock attempts to return
      -EINVAL, which due to the u8 return type ends up a rather large
      number.  Using this index with the parent_names[] array results
      in an invalid pointer and (usually) a crash in the following
      strcmp().

      This patch adds a check for the parent index being in range,
      ignoring clocks reporting invalid values.

      ASoC: fix broken pxa SoC support

      The previous fix of pxa library support, which was introduced to fix the
      library dependency, broke the previous SoC behavior, where a machine
      code binding pxa2xx-ac97 with a coded relied on :
       - sound/soc/pxa/pxa2xx-ac97.c
       - sound/soc/codecs/XXX.c

      For example, the mioa701_wm9713.c machine code is currently broken. The
      "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
      compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
      in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

      Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
      pxa2xx-ac97 compilation.

      arm/arm64: KVM: vgic: Check for !irqchip_in_kernel() when mapping 
resources

      Until b26e5fdac43c ("arm/arm64: KVM: introduce per-VM ops"),
      kvm_vgic_map_resources() used to include a check on irqchip_in_kernel(),
      and vgic_v2_map_resources() still has it.

      But now vm_ops are not initialized until we call kvm_vgic_create().
      Therefore kvm_vgic_map_resources() can being called without a VGIC,
      and we die because vm_ops.map_resources is NULL.

      Fixing this restores QEMU's kernel-irqchip=off option to a working state,
      allowing to use GIC emulation in userspace.

      KVM: s390: Replace incorrect atomic_or with atomic_andnot

      The offending commit accidentally replaces an atomic_clear with an
      atomic_or instead of an atomic_andnot in kvm_s390_vcpu_request_handled.
      The symptom is that kvm guests on s390 hang on startup.
      This patch simply replaces the incorrect atomic_or with atomic_andnot

       "This is the first round of GPIO fixes for v4.3.  Quite a lot of
        patches, but the influx of new stuff in the merge window was equally
        big, so I'm not surprised.

         - Return value checks and thus nicer errorpath for two drivers.

         - Make GPIO_RCAR arch neutral.

         - Propagate errors from GPIO chip ->get() vtable call.  It turned out
           these can actually fail sometimes, especially on slowpath
           controllers doing I2C traffic and similar.

         - Update documentation to be in sync with the massive changes in the
           v4.3 merge window, phew.

         - Handle deferred probe properly in the OMAP driver.

         - Get rid of surplus MODULE_ALIAS() from sx150x"

      sh: Kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      x86/platform: Fix Geode LX timekeeping in the generic x86 build

      In 2007, commit 07190a08eef36 ("Mark TSC on GeodeLX reliable")
      bypassed verification of the TSC on Geode LX. However, this code
      (now in the check_system_tsc_reliable() function in
      arch/x86/kernel/tsc.c) was only present if CONFIG_MGEODE_LX was
      set.

      OpenWRT has recently started building its generic Geode target
      for Geode GX, not LX, to include support for additional
      platforms. This broke the timekeeping on LX-based devices,
      because the TSC wasn't marked as reliable:
      https://dev.openwrt.org/ticket/20531

      By adding a runtime check on is_geode_lx(), we can also include
      the fix if CONFIG_MGEODEGX1 or CONFIG_X86_GENERIC are set, thus
      fixing the problem.

      arm: KVM: Fix incorrect device to IPA mapping

      A critical bug has been found in device memory stage1 translation for
      VMs with more then 4GB of address space. Once vm_pgoff size is smaller
      then pa (which is true for LPAE case, u32 and u64 respectively) some
      more significant bits of pa may be lost as a shift operation is performed
      on u32 and later cast onto u64.

      Example: vm_pgoff(u32)=0x00210030, PAGE_SHIFT=12
              expected pa(u64):   0x0000002010030000
              produced pa(u64):   0x0000000010030000

      The fix is to change the order of operations (casting first onto 
phys_addr_t
      and then shifting).

      genirq: Remove irq argument from irq flow handlers

      Most interrupt flow handlers do not use the irq argument. Those few
      which use it can retrieve the irq number from the irq descriptor.

      Remove the argument.

      Search and replace was done with coccinelle and some extra helper
      scripts around it. Thanks to Julia for her help!

      KVM: vmx: fix VPID is 0000H in non-root operation

      Reference SDM 28.1:

      The current VPID is 0000H in the following situations:
      - Outside VMX operation. (This includes operation in system-management
        mode under the default treatment of SMIs and SMM with VMX operation;
        see Section 34.14.)
      - In VMX root operation.
      - In VMX non-root operation when the â??enable VPIDâ?? VM-execution 
control
        is 0.

      The VPID should never be 0000H in non-root operation when "enable VPID"
      VM-execution control is 1. However, commit 34a1cd60 ("kvm: x86: vmx:
      move some vmx setting from vmx_init() to hardware_setup()") remove the
      codes which reserve 0000H for VMX root operation.

      This patch fix it by again reserving 0000H for VMX root operation.

      powerpc/mm: Recompute hash value after a failed update

      If we had secondary hash flag set, we ended up modifying hash value in
      the updatepp code path. Hence with a failed updatepp we will be using
      a wrong hash value for the following hash insert. Fix this by
      recomputing hash before insert.

      Without this patch we can end up with using wrong slot number in linux
      pte. That can result in us missing an hash pte update or invalidate
      which can cause memory corruption or even machine check.

      KVM: add halt_attempted_poll to VCPU stats

      This new statistic can help diagnosing VCPUs that, for any reason,
      trigger bad behavior of halt_poll_ns autotuning.

      For example, say halt_poll_ns = 480000, and wakeups are spaced exactly
      like 479us, 481us, 479us, 481us. Then KVM always fails polling and wastes
      10+20+40+80+160+320+480 = 1110 microseconds out of every
      479+481+479+481+479+481+479 = 3359 microseconds. The VCPU then
      is consuming about 30% more CPU than it would use without
      polling.  This would show as an abnormally high number of
      attempted polling compared to the successful polls.

      ARM: fix Thumb2 signal handling when ARMv6 is enabled

      When a kernel is built covering ARMv6 to ARMv7, we omit to clear the
      IT state when entering a signal handler.  This can cause the first
      few instructions to be conditionally executed depending on the parent
      context.

      In any case, the original test for >= ARMv7 is broken - ARMv6 can have
      Thumb-2 support as well, and an ARMv6T2 specific build would omit this
      code too.

      Relax the test back to ARMv6 or greater.  This results in us always
      clearing the IT state bits in the PSR, even on CPUs where these bits
      are reserved.  However, they're reserved for the IT state, so this
      should cause no harm.

      dax: fix O_DIRECT I/O to the last block of a blockdev

      commit bbab37ddc20b (block: Add support for DAX reads/writes to
      block devices) caused a regression in mkfs.xfs.  That utility
      sets the block size of the device to the logical block size
      using the BLKBSZSET ioctl, and then issues a single sector read
      from the last sector of the device.  This results in the dax_io
      code trying to do a page-sized read from 512 bytes from the end
      of the device.  The result is -ERANGE being returned to userspace.

      The fix is to align the block to the page size before calling
      get_block.

      PCI: Revert "PCI: Call pci_read_bridge_bases() from core instead of arch 
code"

      Revert dff22d2054b5 ("PCI: Call pci_read_bridge_bases() from core instead
      of arch code").

      Reading PCI bridge windows is not arch-specific in itself, but there is 
PCI
      core code that doesn't work correctly if we read them too early.  For
      example, Hannes found this case on an ARM Freescale i.mx6 board:

        pci_bus 0000:00: root bus resource [mem 0x01000000-0x01efffff]
        pci 0000:00:00.0: PCI bridge to [bus 01-ff]
        pci 0000:00:00.0: BAR 8: no space for [mem size 0x01000000] (mem window)
        pci 0000:01:00.0: BAR 2: failed to assign [mem size 0x00200000]
        pci 0000:01:00.0: BAR 1: failed to assign [mem size 0x00004000]
        pci 0000:01:00.0: BAR 0: failed to assign [mem size 0x00000100]

      The 00:00.0 mem window needs to be at least 3MB: the 01:00.0 device needs
      0x204100 of space, and mem windows are megabyte-aligned.

      Bus sizing can increase a bridge window size, but never *decrease* it (see
      d65245c3297a ("PCI: don't shrink bridge resources")).  Prior to
      dff22d2054b5, ARM didn't read bridge windows at all, so the "original 
size"
      was zero, and we assigned a 3MB window.

      After dff22d2054b5, we read the bridge windows before sizing the bus.  The
      firmware programmed a 16MB window (size 0x01000000) in 00:00.0, and since
      we never decrease the size, we kept 16MB even though we only needed 3MB.
      But 16MB doesn't fit in the host bridge aperture, so we failed to assign
      space for the window and the downstream devices.

      I think this is a defect in the PCI core: we shouldn't rely on the 
firmware
      to assign sensible windows.

      Ray reported a similar problem, also on ARM, with Broadcom iProc.

      Issues like this are too hard to fix right now, so revert dff22d2054b5.

      genirq: Update the comment for generic_handle_irq_desc

      __do_IRQ() was removed by commit 1c77ff2 "genirq: Remove __do_IRQ",
      but the comment referring to __do_IRQ() was left.

      Update the comment for generic_handle_irq_desc().

      irqchip/renesas-irqc: Propagate wake-up settings to parent

      The renesas-irqc interrupt controller is cascaded to the GIC, but its
      driver doesn't propagate wake-up settings to the parent interrupt
      controller.

      Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and
      MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and
      wake-up through gpio-keys now fails on r8a73a4/ape6evm.

      Fix this by propagating wake-up settings to the parent interrupt
      controller. There's no need to handle irq_set_irq_wake() failures, as
      the renesas-irqc interrupt controller is always cascaded to a GIC, and
      the GIC driver always sets SKIP_SET_WAKE since the aforementioned
      commit.

      After GICv2m was enabled for 32-bit ARM kernel, a warning popped up:

      irqchip/gic-v3-its: Add missing cache flushes

      When the ITS is configured for non-cacheable transactions, make sure
      that the allocated, zeroed memory is flushed to the Point of
      Coherency, allowing the ITS to observe the zeros instead of random
      garbage (or even get its own data overwritten by zeros being evicted
      from the cache...).

      irqchip/GIC: Add workaround for aliased GIC400

      The GICv2 architecture mandates that the two 4kB GIC regions are
      contiguous, and on two separate physical pages (so that access to
      the second page can be trapped by a hypervisor). This doesn't work
      very well when PAGE_SIZE is 64kB.

      A relatively common hack^Wway to work around this is to alias each
      4kB region over its own 64kB page. Of course in this case, the base
      address you want to use is not really the begining of the region,
      but base + 60kB (so that you get a contiguous 8kB region over two
      distinct pages).

      Normally, this would be described in DT with a new property, but
      some HW is already out there, and the firmware makes sure that
      it will override whatever you put in the GIC node. Duh. And of course,
      said firmware source code is not available, despite being based
      on u-boot.

      The workaround is to detect the case where the CPU interface size
      is set to 128kB, and verify the aliasing by checking that the ID
      register for GIC400 (which is the only GIC wired this way so far)
      is the same at base and base + 0xF000. In this case, we update
      the GIC base address and let it roll.

      And if you feel slightly sick by looking at this, rest assured that
      I do too...

      platform-msi: Do not cache msi_desc in handler_data

      The current implementation of platform MSI caches the msi_desc
      pointer in irq_data::handler_data. This is a bit silly, as
      we also have irq_data::msi_desc, which is perfectly valid.

      Remove the useless assignment and simplify the whole flow.

      kvm: fix zero length mmio searching

      Currently, if we had a zero length mmio eventfd assigned on
      KVM_MMIO_BUS. It will never be found by kvm_io_bus_cmp() since it
      always compares the kvm_io_range() with the length that guest
      wrote. This will cause e.g for vhost, kick will be trapped by qemu
      userspace instead of vhost. Fixing this by using zero length if an
      iodevice is zero length.

      kvm: fix double free for fast mmio eventfd

      We register wildcard mmio eventfd on two buses, once for KVM_MMIO_BUS
      and once on KVM_FAST_MMIO_BUS but with a single iodev
      instance. This will lead to an issue: kvm_io_bus_destroy() knows
      nothing about the devices on two buses pointing to a single dev. Which
      will lead to double free[1] during exit. Fix this by allocating two
      instances of iodevs then registering one on KVM_MMIO_BUS and another
      on KVM_FAST_MMIO_BUS.

      This patch ensures that the register is initialised so that all traps

      perf evlist: Remove redundant validation from propagate_maps()

      The validation checks that the values that were just assigned, got
      assigned i.e. the error can't ever happen.  Subsequent patches will call
      this code in places where errors are not being returned.  Changing those
      code paths to return this non-existent error is counter-productive, so
      just remove it.

      That in turn results in perf_evlist__set_maps not needing to return an
      error, but callers aren't checking it either, so remove that too.

      cxl: Fix build failure due to -Wunused-variable behaviour change

      A recent change in gcc caused this build failure:

      
/var/lib/jenkins/workspace/gcc_kernel_build/linux/drivers/misc/cxl/cxl.h:72:27:
      error: â??CXL_PSL_DLCNTLâ?? defined but not used 
[-Werror=unused-const-variable]
       static const cxl_p1_reg_t CXL_PSL_DLCNTL  = {0x0060};

      Because of this gcc commit:

      Commit 1bca8cbd0c68366f07277f98ce6963e10c2aa617 by mark
      PR28901 -Wunused-variable ignores unused const initialised variables in C
      12 years ago it was decided that -Wunused-variable shouldn't warn about
      static const variables because some code used const static char rcsid[]
      strings which were never used but wanted in the code anyway. But as the
      bug points out this hides some real bugs. These days the usage of
      rcsids is not very popular anymore. So this patch changes the default
      to warn about unused static const variables in C with
      -Wunused-variable. And it adds a new option -Wno-unused-const-variable
      to turn this warning off. For C++ this new warning is off by default,
      since const variables can be used as #defines in C++. New testcases for
      the new defaults in C and C++ are included testing the new warning and
      suppressing it with an unused attribute or using
      -Wno-unused-const-variable. gcc/ChangeLog

      The cxl driver uses static consts in place of #defines in some cases
      for type safety, so this change causes the driver to fail to build on
      new copilers as these constants are not all used in every file that
      imports the header. Suppress the warning for this driver to return to
      the old behaviour of -Wunused-variable.

      cxl: Fix unbalanced pci_dev_get in cxl_probe

      Currently the first thing we do in cxl_probe is to grab a reference
      on the pci device. Later on, we call device_register on our adapter.
      In our remove path, we call device_unregister, but we never call
      pci_dev_put. We therefore leak the device every time we do a
      reflash.

      device_register/unregister is sufficient to hold the reference.
      Therefore, drop the call to pci_dev_get.

      Here's why this is safe.
      The proposed cxl_probe(pdev) calls cxl_adapter_init:
          a) init calls cxl_adapter_alloc, which creates a struct cxl,
             conventionally called adapter. This struct contains a
             device entry, adapter->dev.

          b) init calls cxl_configure_adapter, where we set
             adapter->dev.parent = &dev->dev (here dev is the pci dev)

      So at this point, the cxl adapter's device's parent is the PCI
      device that I want to be refcounted properly.

          c) init calls cxl_register_adapter
             *) cxl_register_adapter calls device_register(&adapter->dev)

      So now we're in device_register, where dev is the adapter device, and
      we want to know if the PCI device is safe after we return.

      device_register(&adapter->dev) calls device_initialize() and then
      device_add().

      device_add() does a get_device(). device_add() also explicitly grabs
      the device's parent, and calls get_device() on it:

               parent = get_device(dev->parent);

      So therefore, device_register() takes a lock on the parent PCI dev,
      which is what pci_dev_get() was guarding. pci_dev_get() can therefore
      be safely removed.

      drm/ttm: Fix memory space allocation v2

      In the event that TTM doesn't find a compatible memory type for the
      driver's first placement choice (placement without eviction), TTM
      returns -EINVAL without trying the driver's second choice.
      This causes problems on vmwgfx when VRAM is disabled before first modeset
      and during VT switches when fbdev is not enabled.

      Fix this by also trying the driver's second choice before returning
      -EINVAL.

      v2: Also check that man->use_type is true for the driver's second choice.
      Fixes a bug where disallowed memory types could be used.

      btrfs: skip waiting on ordered range for special files

      In btrfs_evict_inode, we properly truncate the page cache for evicted
      inodes but then we call btrfs_wait_ordered_range for every inode as well.
      It's the right thing to do for regular files but results in incorrect
      behavior for device inodes for block devices.

      filemap_fdatawrite_range gets called with inode->i_mapping which gets
      resolved to the block device inode before getting passed to
      wbc_attach_fdatawrite_inode and ultimately to inode_to_bdi.  What happens
      next depends on whether there's an open file handle associated with the
      inode.  If there is, we write to the block device, which is unexpected
      behavior.  If there isn't, we through normally and inode->i_data is used.
      We can also end up racing against open/close which can result in crashes
      when i_mapping points to a block device inode that has been closed.

      Since there can't be any page cache associated with special file inodes,
      it's safe to skip the btrfs_wait_ordered_range call entirely and avoid
      the problem.

      Btrfs: fix read corruption of compressed and shared extents

      If a file has a range pointing to a compressed extent, followed by
      another range that points to the same compressed extent and a read
      operation attempts to read both ranges (either completely or part of
      them), the pages that correspond to the second range are incorrectly
      filled with zeroes.

      Consider the following example:

        File layout
        [0 - 8K]                      [8K - 24K]
            |                             |
            |                             |
         points to extent X,         points to extent X,
         offset 4K, length of 8K     offset 0, length 16K

        [extent X, compressed length = 4K uncompressed length = 16K]

      If a readpages() call spans the 2 ranges, a single bio to read the extent
      is submitted - extent_io.c:submit_extent_page() would only create a new
      bio to cover the second range pointing to the extent if the extent it
      points to had a different logical address than the extent associated with
      the first range. This has a consequence of the compressed read end io
      handler (compression.c:end_compressed_bio_read()) finish once the extent
      is decompressed into the pages covering the first range, leaving the
      remaining pages (belonging to the second range) filled with zeroes (done
      by compression.c:btrfs_clear_biovec_end()).

      So fix this by submitting the current bio whenever we find a range
      pointing to a compressed extent that was preceded by a range with a
      different extent map. This is the simplest solution for this corner
      case. Making the end io callback populate both ranges (or more, if we
      have multiple pointing to the same extent) is a much more complex
      solution since each bio is tightly coupled with a single extent map and
      the extent maps associated to the ranges pointing to the shared extent
      can have different offsets and lengths.

      The following test case for fstests triggers the issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

      selftests/seccomp: add support for s390

      This adds support for s390 to the seccomp selftests. Some improvements
      were made to enhance the accuracy of failure reporting, and additional
      tests were added to validate assumptions about the currently traced
      syscall. Also adds early asserts for running on older kernels to avoid
      noise when the seccomp syscall is not implemented.

      seltests/zram: fix syntax error

      Not all shells define a variable UID. This is a bash and zsh feature only.
      In other shells, the UID variable is not defined, so here test command
      expands to [ != 0 ] which is a syntax error.

      This available buffer will not be read since its size is smaller than

      x86/apic: Serialize LVTT and TSC_DEADLINE writes

      The APIC LVTT register is MMIO mapped but the TSC_DEADLINE register is an
      MSR. The write to the TSC_DEADLINE MSR is not serializing, so it's not
      guaranteed that the write to LVTT has reached the APIC before the
      TSC_DEADLINE MSR is written. In such a case the write to the MSR is
      ignored and as a consequence the local timer interrupt never fires.

      The SDM decribes this issue for xAPIC and x2APIC modes. The
      serialization methods recommended by the SDM differ.

      xAPIC:
       "1. Memory-mapped write to LVT Timer Register, setting bits 18:17 to 10b.
        2. WRMSR to the IA32_TSC_DEADLINE MSR a value much larger than current 
time-stamp counter.
        3. If RDMSR of the IA32_TSC_DEADLINE MSR returns zero, go to step 2.
        4. WRMSR to the IA32_TSC_DEADLINE MSR the desired deadline."

      x2APIC:
       "To allow for efficient access to the APIC registers in x2APIC mode,
        the serializing semantics of WRMSR are relaxed when writing to the
        APIC registers. Thus, system software should not use 'WRMSR to APIC
        registers in x2APIC mode' as a serializing instruction. Read and write
        accesses to the APIC registers will occur in program order. A WRMSR to
        an APIC register may complete before all preceding stores are globally
        visible; software can prevent this by inserting a serializing
        instruction, an SFENCE, or an MFENCE before the WRMSR."

      The xAPIC method is to just wait for the memory mapped write to hit
      the LVTT by checking whether the MSR write has reached the hardware.
      There is no reason why a proper MFENCE after the memory mapped write would
      not do the same. Andi Kleen confirmed that MFENCE is sufficient for the
      xAPIC case as well.

      Issue MFENCE before writing to the TSC_DEADLINE MSR. This can be done
      unconditionally as all CPUs which have TSC_DEADLINE also have MFENCE
      support.

      x86/ioapic: Force affinity setting in setup_ioapic_dest()

      The recent ioapic cleanups changed the affinity setting in
      setup_ioapic_dest() from a direct write to the hardware to the delayed
      affinity setup via irq_set_affinity().

      That results in a warning from chained_irq_exit():
      WARNING: CPU: 0 PID: 5 at kernel/irq/migration.c:32 irq_move_masked_irq
      [<ffffffff810a0a88>] irq_move_masked_irq+0xb8/0xc0
      [<ffffffff8103c161>] ioapic_ack_level+0x111/0x130
      [<ffffffff812bbfe8>] intel_gpio_irq_handler+0x148/0x1c0

      The reason is that irq_set_affinity() does not write directly to the
      hardware. It marks the affinity setting as pending and executes it
      from the next interrupt. The chained handler infrastructure does not
      take the irq descriptor lock for performance reasons because such a
      chained interrupt is not visible to any interfaces. So the delayed
      affinity setting triggers the warning in irq_move_masked_irq().

      Restore the old behaviour by calling the set_affinity function of the
      ioapic chip in setup_ioapic_dest(). This is safe as none of the
      interrupts can be on the fly at this point.

      dm crypt: constrain crypt device's max_segment_size to PAGE_SIZE

      Setting the dm-crypt device's max_segment_size to PAGE_SIZE is an
      unfortunate constraint that is required to avoid the potential for
      exceeding dm-crypt's underlying device's max_segments limits -- due to
      crypt_alloc_buffer() possibly allocating pages for the encryption bio
      that are not as physically contiguous as the original bio.

      It is interesting to note that this problem was already fixed back in
      2007 via commit 91e106259 ("dm crypt: use bio_add_page").  But Linux 4.0
      commit cf2f1abfb ("dm crypt: don't allocate pages for a partial
      request") regressed dm-crypt back to _not_ using bio_add_page().  But
      given dm-crypt's cpu parallelization changes all depend on commit
      cf2f1abfb's abandoning of the more complex io fragments processing that
      dm-crypt previously had we cannot easily go back to using
      bio_add_page().

      So all said the cleanest way to resolve this issue is to fix dm-crypt to
      properly constrain the original bios entering dm-crypt so the encryption
      bios that dm-crypt generates from the original bios are always
      compatible with the underlying device's max_segments queue limits.

      It should be noted that technically Linux 4.3 does _not_ need this fix
      because of the block core's new late bio-splitting capability.  But, it
      is reasoned, there is little to be gained by having the block core split
      the encrypted bio that is composed of PAGE_SIZE segments.  That said, in
      the future we may revert this change.

      KVM: arm64: add workaround for Cortex-A57 erratum #852523

      When restoring the system register state for an AArch32 guest at EL2,
      writes to DACR32_EL2 may not be correctly synchronised by Cortex-A57,
      which can lead to the guest effectively running with junk in the DACR
      and running into unexpected domain faults.

      This patch works around the issue by re-ordering our restoration of the
      AArch32 register aliases so that they happen before the AArch64 system
      registers. Ensuring that the registers are restored in this order
      guarantees that they will be correctly synchronised by the core.

      If there is already some polling ongoing, it's impossible to disable the

      is passed as part of the thermal zone's thermal zone parameters.  If
      that parameter is not provided, it doesn't register with the thermal
      zone.

      While this parameter is strongly recommended for optimal performance, it
      doesn't need to be mandatory.  Relax the requirement and allow the
      governor to bind to thermal zones that don't provide it by estimating it
      from the cooling devices' power model.

      arm64: pgtable: use a single bit for PTE_WRITE regardless of DBM

      Depending on CONFIG_ARM64_HW_AFDBM, we use either bit 57 or 51 of the
      pte to represent PTE_WRITE. Given that bit 51 is reserved prior to
      ARMv8.1, we can just use that bit regardless of the config option. That
      also matches what happens if a kernel configured with ARM64_HW_AFDBM=y
      is run on a CPU without the DBM functionality.

      arm64: Fix pte_modify() to preserve the hardware dirty information

      The pte_modify() function with hardware AF/DBM enabled must transfer the
      hardware dirty information to the software PTE_DIRTY bit. However, it
      was setting this bit in newprot and the mask does not cover such bit.
      This patch sets PTE_DIRTY on the original pte which will be preserved in
      the returned value.

      arm64: Fix the pte_hw_dirty() check when AF/DBM is enabled

      Commit 2f4b829c625e ("arm64: Add support for hardware updates of the
      access and dirty pte bits") introduced support for handling hardware
      updates of the access flag and dirty status. The PTE is automatically
      dirtied in hardware (if supported) by clearing the PTE_RDONLY bit when
      the PTE_DBM/PTE_WRITE bit is set. The pte_hw_dirty() macro was added to
      detect a hardware dirtied pte. The pte_dirty() macro checks for both
      software PTE_DIRTY and pte_hw_dirty().

      Functions like pte_modify() clear the PTE_RDONLY bit since it is meant
      to be set in set_pte_at() when written to memory. In such cases,
      pte_hw_dirty() would return true even though such pte is clean. This
      patch changes pte_hw_dirty() to test the PTE_DBM/PTE_WRITE bit together
      with PTE_RDONLY.

      x86/ldt: Fix small LDT allocation for Xen

      While the following commit:

        37868fe113 ("x86/ldt: Make modify_ldt synchronous")

      added a nice comment explaining that Xen needs page-aligned
      whole page chunks for guest descriptor tables, it then
      nevertheless used kzalloc() on the small size path.

      As I'm unaware of guarantees for kmalloc(PAGE_SIZE, ) to return
      page-aligned memory blocks, I believe this needs to be switched
      back to __get_free_page() (or better get_zeroed_page()).

      drm/vmwgfx: Map the fifo as cached

      On the guest kernel side, previously the FIFO has been mapped write-
      combined. This has worked since VMs up to now has not honored the mapping
      type and mapped the FIFO cached anyway. Since the FIFO is accessed cached
      by the CPU on the virtual device side, this leads to inconsistent
      mappings once the guest starts to honor the mapping types.

      So ask for cached mappings when we map the FIFO. We do this by
      using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup.
      On the TTM side, MOBs, GMRs and VRAM buffers are already requesting
      cached mappings for kernel- and user-space.

      drm/vmwgfx: Fix up user_dmabuf refcounting

      If user space calls unreference on a user_dmabuf it will typically
      kill the struct ttm_base_object member which is responsible for the
      user-space visibility. However the dmabuf part may still be alive and
      refcounted. In some situations, like for shared guest-backed surface
      referencing/opening, the driver may try to reference the
      struct ttm_base_object member again, causing an immediate kernel warning
      and a later kernel NULL pointer dereference.

      Fix this by always maintaining a reference on the struct
      ttm_base_object member, in situations where it might subsequently be
      referenced.

      gpio: omap: Fix GPIO numbering for deferred probe

      If gpio-omap probe fails with -EPROBE_DEFER, the GPIO numbering
      keeps increasing. Only increase the gpio count if gpiochip_add()
      was successful as otherwise the numbers will increase for each
      probe attempt.

      The GPIO documentation mentions that GPIOs are mapped by defining a

      sufix is also supported after commit:

      gpio: omap: Fix gpiochip_add() handling for deferred probe

      Currently we gpio-omap breaks if gpiochip_add() returns -EPROBE_DEFER:

      [    0.570000] omap_gpio 48310000.gpio: Could not register gpio chip -517
      ...
      [    3.670000] omap_gpio 48310000.gpio: Unbalanced pm_runtime_enable!

      Let's fix the issue by adding the missing pm_runtime_put() on error.

      drivers: sh: Disable PM runtime for multi-platform ARM with genpd

      If the default PM Domain using PM_CLK is used for PM runtime, the real
      Clock Domain cannot be registered from DT later.

      Hence do not enable it when running a multi-platform kernel with genpd
      support on R-Car or RZ.  The CPG/MSTP Clock Domain driver will take care
      of PM runtime management of the module clocks.

      Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile,
      R-Car, RZ) use DT-based PM Domains to take care of PM runtime management
      of the module clocks, simplify the platform logic by replacing the
      explicit SoC checks by a single check for the presence of MSTP clocks in
      DT.

      Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided
      by checking for the presence of a "#power-domain-cells" property in DT.

      The default PM Domain is still needed for:
        - backwards-compatibility with old DTs that lack PM Domain properties,
        - the CONFIG_PM=n case,
        - legacy (non-DT) ARM/shmobile platforms without genpd support
          (r8a7778, r8a7779),
        - legacy SuperH.

  commit 2619d7e9c92d524cb155ec89fd72875321512e5b
  Author: John Stultz <john.stultz@xxxxxxxxxx>
  Date:   Wed Sep 9 16:07:30 2015 -0700

      time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of 
abs64()

      The internal clocksteering done for fine-grained error
      correction uses a logarithmic approximation, so any time
      adjtimex() adjusts the clock steering, timekeeping_freqadjust()
      quickly approximates the correct clock frequency over a series
      of ticks.

      Unfortunately, the logic in timekeeping_freqadjust(), introduced
      in commit:

        dc491596f639 ("timekeeping: Rework frequency adjustments to work better 
w/ nohz")

      used the abs() function with a s64 error value to calculate the
      size of the approximated adjustment to be made.

      Per include/linux/kernel.h:

        "abs() should not be used for 64-bit types (s64, u64, long long) - use 
abs64()".

      Thus on 32-bit platforms, this resulted in the clocksteering to
      take a quite dampended random walk trying to converge on the
      proper frequency, which caused the adjustments to be made much
      slower then intended (most easily observed when large
      adjustments are made).

      This patch fixes the issue by using abs64() instead.

      blk: rq_data_dir() should not return a boolean

      rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
      a boolean value.

      Now, admittedly the "!= 0" doesn't really change the value (0 stays as
      zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
      causes gcc to warn about the construct

          switch (rq_data_dir(req)) {
              case READ:
                  ...
              case WRITE:
                  ...

      that we have in a few drivers.

      Now, the gcc warning is silly and stupid (it seems to warn not about the
      switch value having a different type from the case statements, but about
      _any_ boolean switch value), but in this case the code itself is silly
      and stupid too, so let's just change it, and get rid of warnings like
      this:

        drivers/block/hd.c: In function â??hd_requestâ??:
        drivers/block/hd.c:630:11: warning: switch condition has boolean value 
[-Wswitch-bool]
           switch (rq_data_dir(req)) {

      The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
      commit 5953316dbf90 ("block: make rq->cmd_flags be 64-bit") and is
      presumably because the old code (that just did a logical 'and' with 1)
      would then end up making the type of rq_data_dir() be u64 too.

      But if we want to retain the old regular integer type, let's just cast
      the result to 'int' rather than use that rather odd '!= 0'.

      writeback: plug writeback in wb_writeback() and writeback_inodes_wb()

      We had to revert the pluggin in writeback_sb_inodes() because the
      wb->list_lock is held, but we could easily plug at a higher level before
      taking that lock, and unplug after releasing it.  This does that.

      Chris will run performance numbers, just to verify that this approach is
      comparable to the alternative (we could just drop and re-take the lock
      around the blk_finish_plug() rather than these two commits.

      I'd have preferred waiting for actual performance numbers before picking
      one approach over the other, but I don't want to release rc1 with the
      known "sleeping function called from invalid context" issue, so I'll
      pick this cleanup version for now.  But if the numbers show that we
      really want to plug just at the writeback_sb_inodes() level, and we
      should just play ugly games with the spinlock, we'll switch to that.

      thermal: fix intel PCH thermal driver mismerge

      I didn't notice this when merging the thermal code from Zhang, but his
      merge (commit 5a924a07f882: "Merge branches 'thermal-core' and
      'thermal-intel' of .git into next") of the thermal-core and
      thermal-intel branches was wrong.

      In thermal-core, commit 17e8351a7739 ("thermal: consistently use int for
      temperatures") converted the thermal layer to use "int" for
      temperatures.

      But in parallel, in the thermal-intel branch commit d0a12625d2ff
      ("thermal: Add Intel PCH thermal driver") added support for the intel
      PCH thermal sensor using the old interfaces that used "unsigned long"
      pointers.

      This resulted in warnings like this:

        drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization 
from incompatible pointer type [-Wincompatible-pointer-types]
          .get_temp = pch_thermal_get_temp,

      mm/early_ioremap: add explicit #include of asm/early_ioremap.h

      Commit 6b0f68e32ea8 ("mm: add utility for early copy from unmapped ram")
      introduces a function copy_from_early_mem() into mm/early_ioremap.c
      which itself calls early_memremap()/early_memunmap().  However, since
      early_memunmap() has not been declared yet at this point in the .c file,
      nor by any explicitly included header files, we are depending on a
      transitive include of asm/early_ioremap.h to declare it, which is
      fragile.

      So instead, include this header explicitly.

      sys_membarrier(): system-wide memory barrier (generic, x86)

      Here is an implementation of a new system call, sys_membarrier(), which
      executes a memory barrier on all threads running on the system.  It is
      implemented by calling synchronize_sched().  It can be used to
      distribute the cost of user-space memory barriers asymmetrically by
      transforming pairs of memory barriers into pairs consisting of
      sys_membarrier() and a compiler barrier.  For synchronization primitives
      that distinguish between read-side and write-side (e.g.  userspace RCU
      [1], rwlocks), the read-side can be accelerated significantly by moving
      the bulk of the memory barrier overhead to the write-side.

      The existing applications of which I am aware that would be improved by
      this system call are as follows:

      * Through Userspace RCU library (http://urcu.so)
        - DNS server (Knot DNS) https://www.knot-dns.cz/
        - Network sniffer (http://netsniff-ng.org/)
        - Distributed object storage (https://sheepdog.github.io/sheepdog/)
        - User-space tracing (http://lttng.org)
        - Network storage system (https://www.gluster.org/)
        - Virtual routers 
(https://events.linuxfoundation.org/sites/events/files/slides/DPDK_RCU_0MQ.pdf)
        - Financial software (https://lkml.org/lkml/2015/3/23/189)

      Those projects use RCU in userspace to increase read-side speed and
      scalability compared to locking.  Especially in the case of RCU used by
      libraries, sys_membarrier can speed up the read-side by moving the bulk of
      the memory barrier cost to synchronize_rcu().

      * Direct users of sys_membarrier
        - core dotnet garbage collector 
(https://github.com/dotnet/coreclr/issues/198)

      Microsoft core dotnet GC developers are planning to use the mprotect()
      side-effect of issuing memory barriers through IPIs as a way to implement
      Windows FlushProcessWriteBuffers() on Linux.  They are referring to
      sys_membarrier in their github thread, specifically stating that
      sys_membarrier() is what they are looking for.

      To explain the benefit of this scheme, let's introduce two example 
threads:

      Thread A (non-frequent, e.g. executing liburcu synchronize_rcu())
      Thread B (frequent, e.g. executing liburcu
      rcu_read_lock()/rcu_read_unlock())

      In a scheme where all smp_mb() in thread A are ordering memory accesses
      with respect to smp_mb() present in Thread B, we can change each
      smp_mb() within Thread A into calls to sys_membarrier() and each
      smp_mb() within Thread B into compiler barriers "barrier()".

      Before the change, we had, for each smp_mb() pairs:

      Thread A                    Thread B
      previous mem accesses       previous mem accesses
      smp_mb()                    smp_mb()
      following mem accesses      following mem accesses

      After the change, these pairs become:

      Thread A                    Thread B
      prev mem accesses           prev mem accesses
      sys_membarrier()            barrier()
      follow mem accesses         follow mem accesses

      As we can see, there are two possible scenarios: either Thread B memory
      accesses do not happen concurrently with Thread A accesses (1), or they
      do (2).

      1) Non-concurrent Thread A vs Thread B accesses:

      Thread A                    Thread B
      prev mem accesses
      sys_membarrier()
      follow mem accesses
                                  prev mem accesses
                                  barrier()
                                  follow mem accesses

      In this case, thread B accesses will be weakly ordered. This is OK,
      because at that point, thread A is not particularly interested in
      ordering them with respect to its own accesses.

      2) Concurrent Thread A vs Thread B accesses

      Thread A                    Thread B
      prev mem accesses           prev mem accesses
      sys_membarrier()            barrier()
      follow mem accesses         follow mem accesses

      In this case, thread B accesses, which are ensured to be in program
      order thanks to the compiler barrier, will be "upgraded" to full
      smp_mb() by synchronize_sched().

      * Benchmarks

      On Intel Xeon E5405 (8 cores)
      (one thread is calling sys_membarrier, the other 7 threads are busy
      looping)

      1000 non-expedited sys_membarrier calls in 33s =3D 33 milliseconds/call.

      * User-space user of this system call: Userspace RCU library

      Both the signal-based and the sys_membarrier userspace RCU schemes
      permit us to remove the memory barrier from the userspace RCU
      rcu_read_lock() and rcu_read_unlock() primitives, thus significantly
      accelerating them. These memory barriers are replaced by compiler
      barriers on the read-side, and all matching memory barriers on the
      write-side are turned into an invocation of a memory barrier on all
      active threads in the process. By letting the kernel perform this
      synchronization rather than dumbly sending a signal to every process
      threads (as we currently do), we diminish the number of unnecessary wake
      ups and only issue the memory barriers on active threads. Non-running
      threads do not need to execute such barrier anyway, because these are
      implied by the scheduler context switches.

      Results in liburcu:

      Operations in 10s, 6 readers, 2 writers:

      memory barriers in reader:    1701557485 reads, 2202847 writes
      signal-based scheme:          9830061167 reads,    6700 writes
      sys_membarrier:               9952759104 reads,     425 writes
      sys_membarrier (dyn. check):  7970328887 reads,     425 writes

      The dynamic sys_membarrier availability check adds some overhead to
      the read-side compared to the signal-based scheme, but besides that,
      sys_membarrier slightly outperforms the signal-based scheme. However,
      this non-expedited sys_membarrier implementation has a much slower grace
      period than signal and memory barrier schemes.

      Besides diminishing the number of wake-ups, one major advantage of the
      membarrier system call over the signal-based scheme is that it does not
      need to reserve a signal. This plays much more nicely with libraries,
      and with processes injected into for tracing purposes, for which we
      cannot expect that signals will be unused by the application.

      An expedited version of this system call can be added later on to speed
      up the grace period. Its implementation will likely depend on reading
      the cpu_curr()->mm without holding each CPU's rq lock.

      This patch adds the system call to x86 and to asm-generic.

      MEMBARRIER(2)              Linux Programmer's Manual             
MEMBARRIER(2)

      NAME
             membarrier - issue memory barriers on a set of threads

      SYNOPSIS
             #include <linux/membarrier.h>

             int membarrier(int cmd, int flags);

      DESCRIPTION
             The cmd argument is one of the following:

             MEMBARRIER_CMD_QUERY
                    Query  the  set  of  supported commands. It returns a 
bitmask of
                    supported commands.

             MEMBARRIER_CMD_SHARED
                    Execute a memory barrier on all threads running on  the  
system.
                    Upon  return from system call, the caller thread is ensured 
that
                    all running threads have passed through a state where all 
memory
                    accesses  to  user-space  addresses  match program order 
between
                    entry to and return from the system  call  (non-running  
threads
                    are de facto in such a state). This covers threads from all 
pro=E2=80=90
                    cesses running on the system.  This command returns 0.

             The flags argument needs to be 0. For future extensions.

             All memory accesses performed  in  program  order  from  each  
targeted
             thread is guaranteed to be ordered with respect to 
sys_membarrier(). If
             we use the semantic "barrier()" to represent a compiler barrier 
forcing
             memory  accesses  to  be performed in program order across the 
barrier,
             and smp_mb() to represent explicit memory barriers forcing full  
memory
             ordering  across  the barrier, we have the following ordering 
table for
             each pair of barrier(), sys_membarrier() and smp_mb():

             The pair ordering is detailed as (O: ordered, X: not ordered):

                                    barrier()   smp_mb() sys_membarrier()
                    barrier()          X           X            O
                    smp_mb()           X           O            O
                    sys_membarrier()   O           O            O

      RETURN VALUE
             On success, these system calls return zero.  On error, -1 is  
returned,
             and errno is set appropriately. For a given command, with flags
             argument set to 0, this system call is guaranteed to always return 
the
             same value until reboot.

      ERRORS
             ENOSYS System call is not implemented.

             EINVAL Invalid arguments.

      MODSIGN: fix a compilation warning in extract-cert

      Fix the following warning when compiling extract-cert:

        scripts/extract-cert.c: In function `write_cert':
        scripts/extract-cert.c:89:2: warning: format not a string literal and 
no format arguments [-Wformat-security]
          ERR(!i2d_X509_bio(wb, x509), cert_dst);

      whereby the ERR() macro is taking cert_dst as the format string.  "%s"
      should be used as the format string as the path could contain special

      IB/ehca: Deprecate driver, move to staging, schedule deletion

      The ehca driver is only supported on IBM machines with a custom EBus.
      As they have opted to build their newer machines using more industry
      standard technology and haven't really been pushing EBus capable
      machines for a while, this driver can now safely be moved to the
      staging area and scheduled for eventual removal.  This plan was brought
      to IBM's attention and received their sign-off.

      Revert "writeback: plug writeback at a high level"

      This reverts commit d353d7587d02116b9732d5c06615aed75a4d3a47.

      Doing the block layer plug/unplug inside writeback_sb_inodes() is
      broken, because that function is actually called with a spinlock held:
      wb->list_lock, as pointed out by Chris Mason.

      Chris suggested just dropping and re-taking the spinlock around the
      blk_finish_plug() call (the plgging itself can happen under the
      spinlock), and that would technically work, but is just disgusting.

      We do something fairly similar - but not quite as disgusting because we
      at least have a better reason for it - in writeback_single_inode(), so
      it's not like the caller can depend on the lock being held over the
      call, but in this case there just isn't any good reason for that
      "release and re-take the lock" pattern.

      [ In general, we should really strive to avoid the "release and retake"
        pattern for locks, because in the general case it can easily cause
        subtle bugs when the caller caches any state around the call that
        might be invalidated by dropping the lock even just temporarily. ]

      But in this case, the plugging should be easy to just move up to the
      callers before the spinlock is taken, which should even improve the
      effectiveness of the plug.  So there is really no good reason to play
      games with locking here.

      I'll send off a test-patch so that Dave Chinner can verify that that
      plug movement works.  In the meantime this just reverts the problematic
      commit and adds a comment to the function so that we hopefully don't
      make this mistake again.

      ARM: 8431/1: fix alignement of __bug_table section entries

      On old ARM chips, unaligned accesses to memory are not trapped and
      fixed.  On module load, symbols are relocated, and the relocation of
      __bug_table symbols is done on a u32 basis. Yet the section is not
      aligned to a multiple of 4 address, but to a multiple of 2.

      This triggers an Oops on pxa architecture, where address 0xbf0021ea

      arm/xen: Enable user access to the kernel before issuing a privcmd call

      When Xen is copying data to/from the guest it will check if the kernel
      has the right to do the access. If not, the hypercall will return an
      error.

      After the commit a5e090acbf545c0a3b04080f8a488b17ec41fe02 "ARM:
      software-based privileged-no-access support", the kernel can't access
      any longer the user space by default. This will result to fail on every
      hypercall made by the userspace (i.e via privcmd).

      We have to enable the userspace access and then restore the correct
      permission every time the privcmd is used to made an hypercall.

      I didn't find generic helpers to do a these operations, so the change
      is only arm32 specific.

      ARM: domains: add memory dependencies to get_domain/set_domain

      We need to have memory dependencies on get_domain/set_domain to avoid
      the compiler over-optimising these inline assembly instructions.

      Loads/stores must not be reordered across a set_domain(), so introduce
      a compiler barrier for that assembly.

      The value of get_domain() must not be cached across a set_domain(), but
      we still want to allow the compiler to optimise it away.  Introduce a
      dependency on current_thread_info()->cpu_domain to avoid this; the new
      memory clobber in set_domain() should therefore cause the compiler to
      re-load this.  The other advantage of using this is we should have its
      address in the register set already, or very soon after at most call
      sites.

      block: blkg_destroy_all() should clear q->root_blkg and ->root_rl.blkg

      While making the root blkg unconditional, ec13b1d6f0a0 ("blkcg: always
      create the blkcg_gq for the root blkcg") removed the part which clears
      q->root_blkg and ->root_rl.blkg during q exit.  This leaves the two
      pointers dangling after blkg_destroy_all().  blk-throttle exit path
      performs blkg traversals and dereferences ->root_blkg and can lead to
      the following oops.

      While the bug is a straigh-forward use-after-free bug, it is tricky to
      reproduce because blkg release is RCU protected and the rest of exit
      path usually finishes before RCU grace period.

      This patch fixes the bug by updating blkg_destro_all() to clear
      q->root_blkg and ->root_rl.blkg.

      block: Copy a user iovec if it includes gaps

      For drivers that don't support gaps in the SG lists handed to
      them we must bounce (copy the user buffers) and pass a bio that
      does not include gaps. This doesn't matter for any current user,
      but will help to allow iser which can't handle gaps to use the
      block virtual boundary instead of using driver-local bounce
      buffering when handling SG_IO commands.

      This is only theoretical at the moment given that the only

      itself and the scsi target (which generate well aligned integrity
      payloads). But when we will expose integrity meta-data to user-space,
      we'll need to refuse appending a page with a gap (if the queue
      virtual boundary is set).

      CIFS: fix type confusion in copy offload ioctl

      This might lead to local privilege escalation (code execution as
      kernel) for systems where the following conditions are met:

       - CONFIG_CIFS_SMB2 and CONFIG_CIFS_POSIX are enabled
       - a cifs filesystem is mounted where:
        - the mount option "vers" was used and set to a value >=2.0
        - the attacker has write access to at least one file on the filesystem

      To attack this, an attacker would have to guess the target_tcon
      pointer (but guessing wrong doesn't cause a crash, it just returns an
      error code) and win a narrow race.

      This does nothing, and there are many other places where
      transport_cmd_check_stop_to_fabric()'s retval is not checked>, If we
      wanted to check it here, we should probably do it those other places too.

      target: Attach EXTENDED_COPY local I/O descriptors to xcopy_pt_sess

      This patch is a >= v4.1 regression bug-fix where control CDB
      emulation logic in commit 38b57f82 now expects a se_cmd->se_sess
      pointer to exist when determining T10-PI support is to be exposed
      for initiator host ports.

      To address this bug, go ahead and add locally generated se_cmd
      descriptors for copy-offload block-copy to it's own stand-alone
      se_session nexus, while the parent EXTENDED_COPY se_cmd descriptor
      remains associated with it's originating se_cmd->se_sess nexus.

      Note a valid se_cmd->se_sess is also required for future support
      of WRITE_INSERT and READ_STRIP software emulation when submitting
      backend I/O to se_device that exposes T10-PI suport.

      target/qla2xxx: Honor max_data_sg_nents I/O transfer limit

      This patch adds an optional fabric driver provided SGL limit
      that target-core will honor as it's own internal I/O maximum
      transfer length limit, as exposed by EVPD=0xb0 block limits
      parameters.

      This is required for handling cases when host I/O transfer
      length exceeds the requested EVPD block limits maximum
      transfer length. The initial user of this logic is qla2xxx,
      so that we can avoid having to reject I/Os from some legacy
      FC hosts where EVPD=0xb0 parameters are not honored.

      When se_cmd payload length exceeds the provided limit in
      target_check_max_data_sg_nents() code, se_cmd->data_length +
      se_cmd->prot_length are reset with se_cmd->residual_count
      plus underflow bit for outgoing TFO response callbacks.
      It also checks for existing CDB level underflow + overflow
      and recalculates final residual_count as necessary.

      Note this patch currently assumes 1:1 mapping of PAGE_SIZE
      per struct scatterlist entry.

      As Peterz pointed out:

      | So the normal rules for changing task_struct::cpus_allowed are holding
      | both pi_lock and rq->lock, such that holding either stabilizes the mask.
      |
      | This is so that wakeup can happen without rq->lock and load-balance
      | without pi_lock.
      |
      | From this we already get the relaxation that we can omit acquiring
      | rq->lock if the task is not on the rq, because in that case
      | load-balancing will not apply to it.
      |
      | ** these are the rules currently tested in do_set_cpus_allowed() **
      |
      | Now, since __set_cpus_allowed_ptr() uses task_rq_lock() which
      | unconditionally acquires both locks, we could get away with holding just
      | rq->lock when on_rq for modification because that'd still exclude
      | __set_cpus_allowed_ptr(), it would also work against
      | __kthread_bind_mask() because that assumes !on_rq.
      |
      | That said, this is all somewhat fragile.
      |
      | Now, I don't think dropping rq->lock is quite as disastrous as it
      | usually is because !cpu_active at this point, which means load-balance
      | will not interfere, but that too is somewhat fragile.
      |
      | So we end up with a choice of two fragile..

      This patch fixes it by following the rules for changing
      task_struct::cpus_allowed with both pi_lock and rq->lock held.

      locking/qspinlock/x86: Fix performance regression under unaccelerated VMs

      Dave ran into horrible performance on a VM without PARAVIRT_SPINLOCKS
      set and Linus noted that the test-and-set implementation was retarded.

      One should spin on the variable with a load, not a RMW.

      While there, remove 'queued' from the name, as the lock isn't queued
      at all, but a simple test-and-set.

      Merge branch 'for-4.3/blkcg' of git://git.kernel.dk/linux-block

      Pull blk-cg updates from Jens Axboe:
       "A bit later in the cycle, but this has been in the block tree for a a
        while.  This is basically four patchsets from Tejun, that improve our
        buffered cgroup writeback.  It was dependent on the other cgroup
        changes, but they went in earlier in this cycle.

        Series 1 is set of 5 patches that has cgroup writeback updates:

         - bdi_writeback iteration fix which could lead to some wb's being
           skipped or repeated during e.g. sync under memory pressure.

         - Simplification of wb work wait mechanism.

         - Writeback tracepoints updated to report cgroup.

        Series 2 is is a set of updates for the CFQ cgroup writeback handling:

           cfq has always charged all async IOs to the root cgroup.  It didn't
           have much choice as writeback didn't know about cgroups and there
           was no way to tell who to blame for a given writeback IO.
           writeback finally grew support for cgroups and now tags each
           writeback IO with the appropriate cgroup to charge it against.

           This patchset updates cfq so that it follows the blkcg each bio is
           tagged with.  Async cfq_queues are now shared across cfq_group,
           which is per-cgroup, instead of per-request_queue cfq_data.  This
           makes all IOs follow the weight based IO resource distribution
           implemented by cfq.

           - Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff.

           - Other misc review points addressed, acks added and rebased.

        Series 3 is the blkcg policy cleanup patches:

           This patchset contains assorted cleanups for blkcg_policy methods
           and blk[c]g_policy_data handling.

           - alloc/free added for blkg_policy_data.  exit dropped.

           - alloc/free added for blkcg_policy_data.

           - blk-throttle's async percpu allocation is replaced with direct
             allocation.

           - all methods now take blk[c]g_policy_data instead of blkcg_gq or
             blkcg.

        And finally, series 4 is a set of patches cleaning up the blkcg stats
        handling:

          blkcg's stats have always been somwhat of a mess.  This patchset
          tries to improve the situation a bit.

           - The following patches added to consolidate blkcg entry point and
             blkg creation.  This is in itself is an improvement and helps
             colllecting common stats on bio issue.

           - per-blkg stats now accounted on bio issue rather than request
             completion so that bio based and request based drivers can behave
             the same way.  The issue was spotted by Vivek.

           - cfq-iosched implements custom recursive stats and blk-throttle
             implements custom per-cpu stats.  This patchset make blkcg core
             support both by default.

           - cfq-iosched and blk-throttle keep track of the same stats
             multiple times.  Unify them"

      drm/qxl: validate monitors config modes

      Due to some recent changes in
      drm_helper_probe_single_connector_modes_merge_bits(), old custom modes
      were not being pruned properly. In current kernels,
      drm_mode_validate_basic() is called to sanity-check each mode in the
      list. If the sanity-check passes, the mode's status gets set to to
      MODE_OK. In older kernels this check was not done, so old custom modes
      would still have a status of MODE_UNVERIFIED at this point, and would
      therefore be pruned later in the function.

      As a result of this new behavior, the list of modes for a device always
      includes every custom mode ever configured for the device, with the
      largest one listed first. Since desktop environments usually choose the
      first preferred mode when a hotplug event is emitted, this had the
      result of making it very difficult for the user to reduce the size of
      the display.

      The qxl driver did implement the mode_valid connector function, but it
      was empty. In order to restore the old behavior where old custom modes
      are pruned, we implement a proper mode_valid function for the qxl
      driver. This function now checks each mode against the last configured
      custom mode and the list of standard modes. If the mode doesn't match
      any of these, its status is set to MODE_BAD so that it will be pruned as
      expected.

      toshiba_acpi: Fix hotkeys registration on some toshiba models

      Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function
      for keymap choosing") changed the *setup_keyboard function to query for
      the Hotkey Event Type to help choose the correct keymap, but turns out
      that here are certain Toshiba models out there not implementing this
      feature, and thus, failing to continue the input device registration and
      leaving such laptops without hotkey support.

      This patch changes such check, and instead of returning an error if
      the Hotkey Event Type is not present, we simply inform userspace about it,
      changing the message printed from err to notice, making the function
      responsible for registering the input device to continue.

      This issue was found on a Toshiba Portege Z30-B, but there might be
      some other models out there affected by this regression as well.

      Now that the rockchip clock subsystem does clock gating with GPIO banks,
      these are no longer enabled once during probe and no longer stay enabled
      for eternity. When all these clocks are disabled, the parent clock 
pclk_peri
      might be disabled too, as no other child claims it. So, we need to add 
pclk_peri
      to the critical clocks.

      pclk_cpu needs to keep running because it is needed for devices like

      not always the case anymore. So add it to the list of critical clocks.

      clk: rockchip: handle critical clocks after registering all clocks

      Currently the registration of critical clocks is done in the function
      shared between rk3066 and rk3188 clock trees. That results in them
      getting handled maybe before all of them are registered.

      Therefore move the critical clock handling down to the end of the soc-
      specific clock registration function, so that all clocks are registered
      before they're maybe handled as critical clock.

      dma-mapping: consolidate dma_set_mask

      Almost everyone implements dma_set_mask the same way, although some time
      that's hidden in ->set_dma_mask methods.

      This patch consolidates those into a common implementation that either
      calls ->set_dma_mask if present or otherwise uses the default
      implementation.  Some architectures used to only call ->set_dma_mask
      after the initial checks, and those instance have been fixed to do the
      full work.  h8300 implemented dma_set_mask bogusly as a no-ops and has
      been fixed.

      Unfortunately some architectures overload unrelated semantics like 
changing
      the dma_ops into it so we still need to allow for an architecture override
      for now.

      dma-mapping: consolidate dma_supported

      Most architectures just call into ->dma_supported, but some also return 1
      if the method is not present, or 0 if no dma ops are present (although
      that should never happeb). Consolidate this more broad version into
      common code.

      Also fix h8300 which inorrectly always returned 0, which would have been
      a problem if it's dma_set_mask implementation wasn't a similarly buggy
      noop.

      As a few architectures have much more elaborate implementations, we
      still allow for arch overrides.

      Currently there are three valid implementations of dma_mapping_error:

       (1) call ->mapping_error
       (2) check for a hardcoded error code

      This patch provides a common implementation that calls ->mapping_error

      returns 0.

      dma-mapping: consolidate dma_{alloc,free}_noncoherent

      Most architectures do not support non-coherent allocations and either
      define dma_{alloc,free}_noncoherent to their coherent versions or stub
      them out.

      Openrisc uses dma_{alloc,free}_attrs to implement them, and only Mips
      implements them directly.

      This patch moves the Openrisc version to common code, and handles the
      DMA_ATTR_NON_CONSISTENT case in the mips dma_map_ops instance.

      Note that actual non-coherent allocations require a dma_cache_sync
      implementation, so if non-coherent allocations didn't work on
      an architecture before this patch they still won't work after it.

      dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}

      Since 2009 we have a nice asm-generic header implementing lots of DMA API
      functions for architectures using struct dma_map_ops, but unfortunately
      it's still missing a lot of APIs that all architectures still have to
      duplicate.

      This series consolidates the remaining functions, although we still need
      arch opt outs for two of them as a few architectures have very
      non-standard implementations.

      This patch (of 5):

      The coherent DMA allocator works the same over all architectures 
supporting
      dma_map operations.

      This patch consolidates them and converges the minor differences:

       - the debug_dma helpers are now called from all architectures, including
         those that were previously missing them
       - dma_alloc_from_coherent and dma_release_from_coherent are now always
         called from the generic alloc/free routines instead of the ops
         dma-mapping-common.h always includes dma-coherent.h to get the 
defintions
         for them, or the stubs if the architecture doesn't support this feature
       - checks for ->alloc / ->free presence are removed.  There is only one
         magic instead of dma_map_ops without them (mic_dma_ops) and that one
         is x86 only anyway.

      Besides that only x86 needs special treatment to replace a default devices
      if none is passed and tweak the gfp_flags.  An optional arch hook is 
provided
      for that.

      mm: make sure all file VMAs have ->vm_ops set

      We rely on vma->vm_ops == NULL to detect anonymous VMA: see
      vma_is_anonymous(), but some drivers doesn't set ->vm_ops.

      As a result we can end up with anonymous page in private file mapping.
      That should not lead to serious misbehaviour, but nevertheless is wrong.

      Let's fix by setting up dummy ->vm_ops for file mmapping if f_op->mmap()
      didn't set its own.

      The patch also adds sanity check into __vma_link_rb(). It will help
      catch broken VMAs which inserted directly into mm_struct via
      insert_vm_struct().

      mm, mpx: add "vm_flags_t vm_flags" arg to do_mmap_pgoff()

      Add the additional "vm_flags_t vm_flags" argument to do_mmap_pgoff(),
      rename it to do_mmap(), and re-introduce do_mmap_pgoff() as a simple
      wrapper on top of do_mmap().  Perhaps we should update the callers of
      do_mmap_pgoff() and kill it later.

      This way mpx_mmap() can simply call do_mmap(vm_flags => VM_MPX) and do not
      play with vm internals.

      After this change mmap_region() has a single user outside of mmap.c,
      arch/tile/mm/elf.c:arch_setup_additional_pages().  It would be nice to
      change arch/tile/ and unexport mmap_region().

      ipc: convert invalid scenarios to use WARN_ON

      Considering Linus' past rants about the (ab)use of BUG in the kernel, I
      took a look at how we deal with such calls in ipc.  Given that any errors
      or corruption in ipc code are most likely contained within the set of
      processes participating in the broken mechanisms, there aren't really many
      strong fatal system failure scenarios that would require a BUG call.
      Also, if something is seriously wrong, ipc might not be the place for such
      a BUG either.

      1. For example, recently, a customer hit one of these BUG_ONs in shm
         after failing shm_lock().  A busted ID imho does not merit a BUG_ON,
         and WARN would have been better.

      2. MSG_COPY functionality of posix msgrcv(2) for checkpoint/restore.
         I don't see how we can hit this anyway -- at least it should be IS_ERR.
          The 'copy' arg from do_msgrcv is always set by calling prepare_copy()
         first and foremost.  We could also probably drop this check altogether.
          Either way, it does not merit a BUG_ON.

      3. No ->fault() callback for the fs getting the corresponding page --
         seems selfish to make the system unusable.

      that len to 0x01ffffff and decompress fails later.

      We could hit this problem with crashkernel booting that uses kexec loading
      kernel above 4GiB.

      We have decompress_* support:
          1. inbuf[]/outbuf[] for kernel preboot.
          2. inbuf[]/flush() for initramfs
          3. fill()/flush() for initrd.
      This bug only affect kernel preboot path that use outbuf[].

      Add __decompress and take real out_buf_len for gunzip instead of guessing
      wrong buf size.

      fs/affs: make root lookup from blkdev logical size

      This patch resolves https://bugzilla.kernel.org/show_bug.cgi?id=16531.

      When logical blkdev size > 512 then sector numbers become larger than the
      device can support.

      Make affs start lookup based on the device's logical sector size instead
      of 512.

      sysctl: fix int -> unsigned long assignments in INT_MIN case

      The following

          if (val < 0)
              *lvalp = (unsigned long)-val;

      is incorrect because the compiler is free to assume -val to be positive
      and use a sign-extend instruction for extending the bit pattern.  This is
      a problem if val == INT_MIN:

          # echo -2147483648 >/proc/sys/dev/scsi/logging_level
          # cat /proc/sys/dev/scsi/logging_level
          -18446744071562067968

      Cast to unsigned long before negation - that way we first sign-extend and
      then negate an unsigned, which is well defined.  With this:

          # cat /proc/sys/dev/scsi/logging_level
          -2147483648

      kexec: export KERNEL_IMAGE_SIZE to vmcoreinfo

      In x86_64, since v2.6.26 the KERNEL_IMAGE_SIZE is changed to 512M, and
      accordingly the MODULES_VADDR is changed to 0xffffffffa0000000.  However,
      in v3.12 Kees Cook introduced kaslr to randomise the location of kernel.
      And the kernel text mapping addr space is enlarged from 512M to 1G.  That
      means now KERNEL_IMAGE_SIZE is variable, its value is 512M when kaslr
      support is not compiled in and 1G when kaslr support is compiled in.
      Accordingly the MODULES_VADDR is changed too to be:

          #define MODULES_VADDR    (__START_KERNEL_map + KERNEL_IMAGE_SIZE)

      So when kaslr is compiled in and enabled, the kernel text mapping addr
      space and modules vaddr space need be adjusted.  Otherwise makedumpfile
      will collapse since the addr for some symbols is not correct.

      Hence KERNEL_IMAGE_SIZE need be exported to vmcoreinfo and got in
      makedumpfile to help calculate MODULES_VADDR.

      kexec: align crash_notes allocation to make it be inside one physical page

      People reported that crash_notes in /proc/vmcore were corrupted and this
      cause crash kdump failure.  With code debugging and log we got the root
      cause.  This is because percpu variable crash_notes are allocated in 2
      vmalloc pages.  Currently percpu is based on vmalloc by default.  Vmalloc
      can't guarantee 2 continuous vmalloc pages are also on 2 continuous
      physical pages.  So when 1st kernel exports the starting address and size
      of crash_notes through sysfs like below:

      /sys/devices/system/cpu/cpux/crash_notes
      /sys/devices/system/cpu/cpux/crash_notes_size

      kdump kernel use them to get the content of crash_notes.  However the 2nd
      part may not be in the next neighbouring physical page as we expected if
      crash_notes are allocated accross 2 vmalloc pages.  That's why
      nhdr_ptr->n_namesz or nhdr_ptr->n_descsz could be very huge in
      update_note_header_size_elf64() and cause note header merging failure or
      some warnings.

      In this patch change to call __alloc_percpu() to passed in the align value
      by rounding crash_notes_size up to the nearest power of two.  This makes
      sure the crash_notes is allocated inside one physical page since
      sizeof(note_buf_t) in all ARCHS is smaller than PAGE_SIZE.  Meanwhile add
      a BUILD_BUG_ON to break compile if size is bigger than PAGE_SIZE since
      crash_notes definitely will be in 2 pages.  That need be avoided, and need
      be reported if it's unavoidable.

      kexec: split kexec_load syscall from kexec core code

      There are two kexec load syscalls, kexec_load another and kexec_file_load.
       kexec_file_load has been splited as kernel/kexec_file.c.  In this patch I
      split kexec_load syscall code to kernel/kexec.c.

      And add a new kconfig option KEXEC_CORE, so we can disable kexec_load and
      use kexec_file_load only, or vice verse.

      The original requirement is from Ted Ts'o, he want kexec kernel signature
      being checked with CONFIG_KEXEC_VERIFY_SIG enabled.  But kexec-tools use
      kexec_load syscall can bypass the checking.

      Vivek Goyal proposed to create a common kconfig option so user can compile
      in only one syscall for loading kexec kernel.  KEXEC/KEXEC_FILE selects
      KEXEC_CORE so that old config files still work.

      Because there's general code need CONFIG_KEXEC_CORE, so I updated all the
      architecture Kconfig with a new option KEXEC_CORE, and let KEXEC selects
      KEXEC_CORE in arch Kconfig.  Also updated general kernel code with to
      kexec_load syscall.

      fs: Don't dump core if the corefile would become world-readable.

      On a filesystem like vfat, all files are created with the same owner
      and mode independent of who created the file. When a vfat filesystem
      is mounted with root as owner of all files and read access for everyone,
      root's processes left world-readable coredumps on it (but other
      users' processes only left empty corefiles when given write access
      because of the uid mismatch).

      Given that the old behavior was inconsistent and insecure, I don't see
      a problem with changing it. Now, all processes refuse to dump core unless
      the resulting corefile will only be readable by their owner.

      fs: if a coredump already exists, unlink and recreate with O_EXCL

      It was possible for an attacking user to trick root (or another user) into
      writing his coredumps into an attacker-readable, pre-existing file using
      rename() or link(), causing the disclosure of secret data from the victim
      process' virtual memory.  Depending on the configuration, it was also
      possible to trick root into overwriting system files with coredumps.  Fix
      that issue by never writing coredumps into existing files.

      Requirements for the attack:
       - The attack only applies if the victim's process has a nonzero
         RLIMIT_CORE and is dumpable.
       - The attacker can trick the victim into coredumping into an
         attacker-writable directory D, either because the core_pattern is
         relative and the victim's cwd is attacker-writable or because an
         absolute core_pattern pointing to a world-writable directory is used.
       - The attacker has one of these:
        A: on a system with protected_hardlinks=0:
           execute access to a folder containing a victim-owned,
           attacker-readable file on the same partition as D, and the
           victim-owned file will be deleted before the main part of the attack
           takes place. (In practice, there are lots of files that fulfill
           this condition, e.g. entries in Debian's /var/lib/dpkg/info/.)
           This does not apply to most Linux systems because most distros set
           protected_hardlinks=1.
        B: on a system with protected_hardlinks=1:
           execute access to a folder containing a victim-owned,
           attacker-readable and attacker-writable file on the same partition
           as D, and the victim-owned file will be deleted before the main part
           of the attack takes place.
           (This seems to be uncommon.)
        C: on any system, independent of protected_hardlinks:
           write access to a non-sticky folder containing a victim-owned,
           attacker-readable file on the same partition as D
           (This seems to be uncommon.)

      The basic idea is that the attacker moves the victim-owned file to where
      he expects the victim process to dump its core.  The victim process dumps
      its core into the existing file, and the attacker reads the coredump from
      it.

      If the attacker can't move the file because he does not have write access
      to the containing directory, he can instead link the file to a directory
      he controls, then wait for the original link to the file to be deleted
      (because the kernel checks that the link count of the corefile is 1).

      A less reliable variant that requires D to be non-sticky works with link()
      and does not require deletion of the original link: link() the file into
      D, but then unlink() it directly before the kernel performs the link count

      kmod: handle UMH_WAIT_PROC from system unbound workqueue

      The UMH_WAIT_PROC handler runs in its own thread in order to make sure
      that waiting for the exec kernel thread completion won't block other
      usermodehelper queued jobs.

      On older workqueue implementations, worklets couldn't sleep without
      blocking the rest of the queue.  But now the workqueue subsystem handles
      that.  Khelper still had the older limitation due to its singlethread
      properties but we replaced it to system unbound workqueues.

      Those are affine to the current node and can block up to some number of
      instances.

      They are a good candidate to handle UMH_WAIT_PROC assuming that we have
      enough system unbound workers to handle lots of parallel usermodehelper
      jobs.

      kmod: use system_unbound_wq instead of khelper

      We need to launch the usermodehelper kernel threads with the widest
      affinity and this is partly why we use khelper.  This workqueue has
      unbound properties and thus a wide affinity inherited by all its children.

      Now khelper also has special properties that we aren't much interested in:
      ordered and singlethread.  There is really no need about ordering as all
      we do is creating kernel threads.  This can be done concurrently.  And
      singlethread is a useless limitation as well.

      The workqueue engine already proposes generic unbound workqueues that
      don't share these useless properties and handle well parallel jobs.

      The only worrysome specific is their affinity to the node of the current
      CPU.  It's fine for creating the usermodehelper kernel threads but those
      inherit this affinity for longer jobs such as requesting modules.

      This patch proposes to use these node affine unbound workqueues assuming
      that a node is sufficient to handle several parallel usermodehelper
      requests.

      kmod: add up-to-date explanations on the purpose of each asynchronous 
levels

      There seem to be quite some confusions on the comments, likely due to
      changes that came after them.

      Now since it's very non obvious why we have 3 levels of asynchronous code
      to implement usermodehelpers, it's important to comment in detail the
      reason of this layout.

      kmod: remove unecessary explicit wide CPU affinity setting

      Khelper is affine to all CPUs.  Now since it creates the
      call_usermodehelper_exec_[a]sync() kernel threads, those inherit the wide
      affinity.

      As such explicitly forcing a wide affinity from those kernel threads
      is like a no-op.

      Just remove it. It's needless and it breaks CPU isolation users who
      rely on workqueue affinity tuning.

      kmod: bunch of internal functions renames

      This patchset does a bunch of cleanups and converts khelper to use system
      unbound workqueues.  The 3 first patches should be uncontroversial.  The
      last 2 patches are debatable.

      Kmod creates kernel threads that perform userspace jobs and we want those
      to have a large affinity in order not to contend busy CPUs.  This is
      (partly) why we use khelper which has a wide affinity that the kernel
      threads it create can inherit from.  Now khelper is a dedicated workqueue
      that has singlethread properties which we aren't interested in.

      Hence those two debatable changes:

      _ We would like to use generic workqueues. System unbound workqueues are
        a very good candidate but they are not wide affine, only node affine.
        Now probably a node is enough to perform many parallel kmod jobs.

      _ We would like to remove the wait_for_helper kernel thread (UMH_WAIT_PROC
        handler) to use the workqueue. It means that if the workqueue blocks,
        and no other worker can take pending kmod request, we can be screwed.
        Now if we have 512 threads, this should be enough.

      This patch (of 5):

      Underscores on function names aren't much verbose to explain the purpose
      of a function.  And kmod has interesting such flavours.

      Lets rename the following functions:

      * __call_usermodehelper -> call_usermodehelper_exec_work
      * ____call_usermodehelper -> call_usermodehelper_exec_async
      * wait_for_helper -> call_usermodehelper_exec_sync

      If request_module() successfully runs modprobe, but modprobe exits with a

      hfs,hfsplus: cache pages correctly between bnode_create and bnode_free

      Pages looked up by __hfs_bnode_create() (called by hfs_bnode_create() and
      hfs_bnode_find() for finding or creating pages corresponding to an inode)
      are immediately kmap()'ed and used (both read and write) and kunmap()'ed,
      and should not be page_cache_release()'ed until hfs_bnode_free().

      This patch fixes a problem I first saw in July 2012: merely running "du"
      on a large hfsplus-mounted directory a few times on a reasonably loaded
      system would get the hfsplus driver all confused and complaining about
      B-tree inconsistencies, and generates a "BUG: Bad page state".  Most
      recently, I can generate this problem on up-to-date Fedora 22 with shipped
      kernel 4.0.5, by running "du /" (="/" + "/home" + "/mnt" + other smaller
      mounts) and "du /mnt" simultaneously on two windows, where /mnt is a
      lightly-used QEMU VM image of the full Mac OS X 10.9:

      $ df -i / /home /mnt
      Filesystem                  Inodes   IUsed      IFree IUse% Mounted on
      /dev/mapper/fedora-root    3276800  551665    2725135   17% /
      /dev/mapper/fedora-home   52879360  716221   52163139    2% /home
      /dev/nbd0p2             4294967295 1387818 4293579477    1% /mnt

      After applying the patch, I was able to run "du /" (60+ times) and "du
      /mnt" (150+ times) continuously and simultaneously for 6+ hours.

      There are many reports of the hfsplus driver getting confused under load
      and generating "BUG: Bad page state" or other similar issues over the
      years.  [1]

      The unpatched code [2] has always been wrong since it entered the kernel
      tree.  The only reason why it gets away with it is that the
      kmap/memcpy/kunmap follow very quickly after the page_cache_release() so
      the kernel has not had a chance to reuse the memory for something else,
      most of the time.

      The current RW driver appears to have followed the design and development
      of the earlier read-only hfsplus driver [3], where-by version 0.1 (Dec
      2001) had a B-tree node-centric approach to
      read_cache_page()/page_cache_release() per bnode_get()/bnode_put(),
      migrating towards version 0.2 (June 2002) of caching and releasing pages
      per inode extents.  When the current RW code first entered the kernel [2]
      in 2005, there was an REF_PAGES conditional (and "//" commented out code)
      to switch between B-node centric paging to inode-centric paging.  There
      was a mistake with the direction of one of the REF_PAGES conditionals in
      __hfs_bnode_create().  In a subsequent "remove debug code" commit [4], the
      read_cache_page()/page_cache_release() per bnode_get()/bnode_put() were
      removed, but a page_cache_release() was mistakenly left in (propagating
      the "REF_PAGES <-> !REF_PAGE" mistake), and the commented-out
      page_cache_release() in bnode_release() (which should be spanned by
      !REF_PAGES) was never enabled.

      fs/coda: fix readlink buffer overflow

      Dan Carpenter discovered a buffer overflow in the Coda file system
      readlink code.  A userspace file system daemon can return a 4096 byte
      result which then triggers a one byte write past the allocated readlink
      result buffer.

      This does not trigger with an unmodified Coda implementation because Coda
      has a 1024 byte limit for symbolic links, however other userspace file
      systems using the Coda kernel module could be affected.

      Although this is an obvious overflow, I don't think this has to be handled
      as too sensitive from a security perspective because the overflow is on
      the Coda userspace daemon side which already needs root to open Coda's
      kernel device and to mount the file system before we get to the point that
      links can be read.

      checkpatch: always check block comment styles

      Some of the block comment tests that are used only for networking are
      appropriate for all patches.

      For example, these styles are not encouraged:

        /*
         block comment without introductory *
        */
      and
        /*
         * block comment with line terminating */

      Remove the networking specific test and add comments.

      There are some infrequent false positives where code is lazily
      commented out using /* and */ rather than using #if 0/#endif blocks
      like:
        /* case foo:
        case bar: */
        case baz:

      lib/test_kasan.c: make kmalloc_oob_krealloc_less more correctly

      In kmalloc_oob_krealloc_less, I think it is better to test
      the size2 boundary.

      If we do not call krealloc, the access of position size1 will still cause
      out-of-bounds and access of position size2 does not.  After call krealloc,
      the access of position size2 cause out-of-bounds.  So using size2 is more
      correct.

      In __bitmap_parselist we can accept whitespaces on head or tail during
      every parsing procedure.  If input has valid ranges, there is no reason to
      reject the user.

      For example, bitmap_parselist(" 1-3, 5, ", &mask, nmaskbits).  After
      separating the string, we get " 1-3", " 5", and " ".  It's possible and
      reasonable to accept such string as long as the parsing result is correct.

      added the kdebug mechanism to this file back in 2009.

      The kdebug macro calls no_printk which always evaluates arguments.

      Most of the kdebug uses have an unnecessary call of
        atomic_read(&cred->usage)

      Make the kdebug macro do nothing by defining it with
        do { if (0) no_printk(...); } while (0)
      when not enabled.

      include/linux/poison.h: fix LIST_POISON{1,2} offset

      Poison pointer values should be small enough to find a room in
      non-mmap'able/hardly-mmap'able space.  E.g.  on x86 "poison pointer space"
      is located starting from 0x0.  Given unprivileged users cannot mmap
      anything below mmap_min_addr, it should be safe to use poison pointers
      lower than mmap_min_addr.

      The current poison pointer values of LIST_POISON{1,2} might be too big for
      mmap_min_addr values equal or less than 1 MB (common case, e.g.  Ubuntu
      uses only 0x10000).  There is little point to use such a big value given
      the "poison pointer space" below 1 MB is not yet exhausted.  Changing it
      to a smaller value solves the problem for small mmap_min_addr setups.

      The values are suggested by Solar Designer:

      proc: change proc_subdir_lock to a rwlock

      The proc_subdir_lock spinlock is used to allow only one task to make
      change to the proc directory structure as well as looking up information
      in it.  However, the information lookup part can actually be entered by
      more than one task as the pde_get() and pde_put() reference count update
      calls in the critical sections are atomic increment and decrement
      respectively and so are safe with concurrent updates.

      The x86 architecture has already used qrwlock which is fair and other
      architectures like ARM are in the process of switching to qrwlock.  So
      unfairness shouldn't be a concern in that conversion.

      This patch changed the proc_subdir_lock to a rwlock in order to enable
      concurrent lookup. The following functions were modified to take a
      write lock:
       - proc_register()
       - remove_proc_entry()
       - remove_proc_subtree()

      The following functions were modified to take a read lock:
       - xlate_proc_name()
       - proc_lookup_de()
       - proc_readdir_de()

      A parallel /proc filesystem search with the "find" command (1000 threads)
      was run on a 4-socket Haswell-EX box (144 threads).  Before the patch, the
      parallel search took about 39s.  After the patch, the parallel find took
      only 25s, a saving of about 14s.

      The micro-benchmark that I used was artificial, but it was used to
      reproduce an exit hanging problem that I saw in real application.  In
      fact, only allow one task to do a lookup seems too limiting to me.

  Author: Calvin Owens <calvinowens@xxxxxx>

      procfs: always expose /proc/<pid>/map_files/ and make it readable

      Currently, /proc/<pid>/map_files/ is restricted to CAP_SYS_ADMIN, and is
      only exposed if CONFIG_CHECKPOINT_RESTORE is set.

      Each mapped file region gets a symlink in /proc/<pid>/map_files/
      corresponding to the virtual address range at which it is mapped.  The
      symlinks work like the symlinks in /proc/<pid>/fd/, so you can follow them
      to the backing file even if that backing file has been unlinked.

      Currently, files which are mapped, unlinked, and closed are impossible to
      stat() from userspace.  Exposing /proc/<pid>/map_files/ closes this
      functionality "hole".

      Not being able to stat() such files makes noticing and explicitly
      accounting for the space they use on the filesystem impossible.  You can
      work around this by summing up the space used by every file in the
      filesystem and subtracting that total from what statfs() tells you, but
      that obviously isn't great, and it becomes unworkable once your filesystem
      becomes large enough.

      This patch moves map_files/ out from behind CONFIG_CHECKPOINT_RESTORE, and
      adjusts the permissions enforced on it as follows:

      * proc_map_files_lookup()
      * proc_map_files_readdir()
      * map_files_d_revalidate()

        Remove the CAP_SYS_ADMIN restriction, leaving only the current
        restriction requiring PTRACE_MODE_READ. The information made
        available to userspace by these three functions is already
        available in /proc/PID/maps with MODE_READ, so I don't see any
        reason to limit them any further (see below for more detail).

      * proc_map_files_follow_link()

        This stub has been added, and requires that the user have
        CAP_SYS_ADMIN in order to follow the links in map_files/,
        since there was concern on LKML both about the potential for
        bypassing permissions on ancestor directories in the path to
        files pointed to, and about what happens with more exotic
        memory mappings created by some drivers (ie dma-buf).

      In older versions of this patch, I changed every permission check in
      the four functions above to enforce MODE_ATTACH instead of MODE_READ.
      This was an oversight on my part, and after revisiting the discussion
      it seems that nobody was concerned about anything outside of what is
      made possible by ->follow_link(). So in this version, I've left the
      checks for PTRACE_MODE_READ as-is.

      proc: export idle flag via kpageflags

      As noted by Minchan, a benefit of reading idle flag from /proc/kpageflags
      is that one can easily filter dirty and/or unevictable pages while
      estimating the size of unused memory.

      Note that idle flag read from /proc/kpageflags may be stale in case the
      page was accessed via a PTE, because it would be too costly to iterate
      over all page mappings on each /proc/kpageflags read to provide an
      up-to-date value.  To make sure the flag is up-to-date one has to read
      /sys/kernel/mm/page_idle/bitmap first.

      mm: introduce idle page tracking

      Knowing the portion of memory that is not used by a certain application or
      memory cgroup (idle memory) can be useful for partitioning the system
      efficiently, e.g.  by setting memory cgroup limits appropriately.
      Currently, the only means to estimate the amount of idle memory provided
      by the kernel is /proc/PID/{clear_refs,smaps}: the user can clear the
      access bit for all pages mapped to a particular process by writing 1 to
      clear_refs, wait for some time, and then count smaps:Referenced.  However,
      this method has two serious shortcomings:

       - it does not count unmapped file pages
       - it affects the reclaimer logic

      To overcome these drawbacks, this patch introduces two new page flags,
      Idle and Young, and a new sysfs file, /sys/kernel/mm/page_idle/bitmap.
      A page's Idle flag can only be set from userspace by setting bit in
      /sys/kernel/mm/page_idle/bitmap at the offset corresponding to the page,
      and it is cleared whenever the page is accessed either through page tables
      (it is cleared in page_referenced() in this case) or using the read(2)
      system call (mark_page_accessed()). Thus by setting the Idle flag for
      pages of a particular workload, which can be found e.g.  by reading
      /proc/PID/pagemap, waiting for some time to let the workload access its
      working set, and then reading the bitmap file, one can estimate the amount
      of pages that are not used by the workload.

      The Young page flag is used to avoid interference with the memory
      reclaimer.  A page's Young flag is set whenever the Access bit of a page
      table entry pointing to the page is cleared by writing to the bitmap file.
      If page_referenced() is called on a Young page, it will add 1 to its
      return value, therefore concealing the fact that the Access bit was
      cleared.

      Note, since there is no room for extra page flags on 32 bit, this feature
      uses extended page flags when compiled on 32 bit.

      mmu-notifier: add clear_young callback

      In the scope of the idle memory tracking feature, which is introduced by
      the following patch, we need to clear the referenced/accessed bit not only
      in primary, but also in secondary ptes.  The latter is required in order
      to estimate wss of KVM VMs.  At the same time we want to avoid flushing
      tlb, because it is quite expensive and it won't really affect the final
      result.

      Currently, there is no function for clearing pte young bit that would meet
      our requirements, so this patch introduces one.  To achieve that we have
      to add a new mmu-notifier callback, clear_young, since there is no method
      for testing-and-clearing a secondary pte w/o flushing tlb.  The new method
      is not mandatory and currently only implemented by KVM.

      hwpoison: use page_cgroup_ino for filtering by memcg

      Hwpoison allows to filter pages by memory cgroup ino.  Currently, it
      calls try_get_mem_cgroup_from_page to obtain the cgroup from a page and
      then its ino using cgroup_ino, but now we have a helper method for
      that, page_cgroup_ino, so use it instead.

      This patch also loosens the hwpoison memcg filter dependency rules - it
      makes it depend on CONFIG_MEMCG instead of CONFIG_MEMCG_SWAP, because
      hwpoison memcg filter does not require anything (nor it used to) from
      CONFIG_MEMCG_SWAP side.

      memcg: add page_cgroup_ino helper

      This patchset introduces a new user API for tracking user memory pages
      that have not been used for a given period of time.  The purpose of this
      is to provide the userspace with the means of tracking a workload's
      working set, i.e.  the set of pages that are actively used by the
      workload.  Knowing the working set size can be useful for partitioning the
      system more efficiently, e.g.  by tuning memory cgroup limits
      appropriately, or for job placement within a compute cluster.

      ==== USE CASES ====

      The unified cgroup hierarchy has memory.low and memory.high knobs, which
      are defined as the low and high boundaries for the workload working set
      size.  However, the working set size of a workload may be unknown or
      change in time.  With this patch set, one can periodically estimate the
      amount of memory unused by each cgroup and tune their memory.low and
      memory.high parameters accordingly, therefore optimizing the overall
      memory utilization.

      Another use case is balancing workloads within a compute cluster.  Knowing
      how much memory is not really used by a workload unit may help take a more
      optimal decision when considering migrating the unit to another node
      within the cluster.

      Also, as noted by Minchan, this would be useful for per-process reclaim
      (https://lwn.net/Articles/545668/). With idle tracking, we could reclaim 
idle
      pages only by smart user memory manager.

      ==== USER API ====

      The user API consists of two new files:

       * /sys/kernel/mm/page_idle/bitmap.  This file implements a bitmap where 
each
         bit corresponds to a page, indexed by PFN. When the bit is set, the
         corresponding page is idle. A page is considered idle if it has not 
been
         accessed since it was marked idle. To mark a page idle one should set 
the
         bit corresponding to the page by writing to the file. A value written 
to the
         file is OR-ed with the current bitmap value. Only user memory pages 
can be
         marked idle, for other page types input is silently ignored. Writing 
to this
         file beyond max PFN results in the ENXIO error. Only available when
         CONFIG_IDLE_PAGE_TRACKING is set.

         This file can be used to estimate the amount of pages that are not
         used by a particular workload as follows:

         1. mark all pages of interest idle by setting corresponding bits in the
            /sys/kernel/mm/page_idle/bitmap
         2. wait until the workload accesses its working set
         3. read /sys/kernel/mm/page_idle/bitmap and count the number of bits 
set

       * /proc/kpagecgroup.  This file contains a 64-bit inode number of the
         memory cgroup each page is charged to, indexed by PFN. Only available 
when
         CONFIG_MEMCG is set.

         This file can be used to find all pages (including unmapped file pages)
         accounted to a particular cgroup. Using 
/sys/kernel/mm/page_idle/bitmap, one
         can then estimate the cgroup working set size.

      For an example of using these files for estimating the amount of unused
      memory pages per each memory cgroup, please see the script attached
      below.

      ==== REASONING ====

      The reason to introduce the new user API instead of using
      /proc/PID/{clear_refs,smaps} is that the latter has two serious
      drawbacks:

       - it does not count unmapped file pages
       - it affects the reclaimer logic

      The new API attempts to overcome them both. For more details on how it
      is achieved, please see the comment to patch 6.

      ==== PATCHSET STRUCTURE ====

      The patch set is organized as follows:

       - patch 1 adds page_cgroup_ino() helper for the sake of
         /proc/kpagecgroup and patches 2-3 do related cleanup
       - patch 4 adds /proc/kpagecgroup, which reports cgroup ino each page is
         charged to
       - patch 5 introduces a new mmu notifier callback, clear_young, which is
         a lightweight version of clear_flush_young; it is used in patch 6
       - patch 6 implements the idle page tracking feature, including the
         userspace API, /sys/kernel/mm/page_idle/bitmap
       - patch 7 exports idle flag via /proc/kpageflags

      ==== SIMILAR WORKS ====

      Originally, the patch for tracking idle memory was proposed back in 2011
      by Michel Lespinasse (see http://lwn.net/Articles/459269/).  The main
      difference between Michel's patch and this one is that Michel implemented
      a kernel space daemon for estimating idle memory size per cgroup while
      this patch only provides the userspace with the minimal API for doing the
      job, leaving the rest up to the userspace.  However, they both share the
      same idea of Idle/Young page flags to avoid affecting the reclaimer logic.

      ==== PERFORMANCE EVALUATION ====

      SPECjvm2008 (https://www.spec.org/jvm2008/) was used to evaluate the
      performance impact introduced by this patch set.  Three runs were carried
      out:

       - base: kernel without the patch
       - patched: patched kernel, the feature is not used
       - patched-active: patched kernel, 1 minute-period daemon is used for
         tracking idle memory

      For tracking idle memory, idlememstat utility was used:

      This patch (of 8):

      Add page_cgroup_ino() helper to memcg.

      This function returns the inode number of the closest online ancestor of
      the memory cgroup a page is charged to.  It is required for exporting
      information about which page is charged to which cgroup to userspace,
      which will be introduced by a following patch.

      Update the zpool and compressor parameters to be changeable at runtime.
      When changed, a new pool is created with the requested zpool/compressor,
      and added as the current pool at the front of the pool list.  Previous
      pools remain in the list only to remove existing compressed pages from.
      The old pool(s) are removed once they become empty.

      zpool: add zpool_has_pool()

      This series makes creation of the zpool and compressor dynamic, so that
      they can be changed at runtime.  This makes using/configuring zswap
      easier, as before this zswap had to be configured at boot time, using boot
      params.

      This uses a single list to track both the zpool and compressor together,
      although Seth had mentioned an alternative which is to track the zpools
      and compressors using separate lists.  In the most common case, only a
      single zpool and single compressor, using one list is slightly simpler
      than using two lists, and for the uncommon case of multiple zpools and/or
      compressors, using one list is slightly less simple (and uses slightly
      more memory, probably) than using two lists.

      This patch (of 4):

      Add zpool_has_pool() function, indicating if the specified type of zpool
      is available (i.e.  zsmalloc or zbud).  This allows checking if a pool is
      available, without actually trying to allocate it, similar to
      crypto_has_alg().

      This is used by a following patch to zswap that enables the dynamic
      runtime creation of zswap zpools.

      tcp_cubic: better follow cubic curve after idle period

      Jana Iyengar found an interesting issue on CUBIC :

      The epoch is only updated/reset initially and when experiencing losses.
      The delta "t" of now - epoch_start can be arbitrary large after app idle
      as well as the bic_target. Consequentially the slope (inverse of
      ca->cnt) would be really large, and eventually ca->cnt would be
      lower-bounded in the end to 2 to have delayed-ACK slow-start behavior.

      This particularly shows up when slow_start_after_idle is disabled
      as a dangerous cwnd inflation (1.5 x RTT) after few seconds of idle
      time.

      Jana initial fix was to reset epoch_start if app limited,
      but Neal pointed out it would ask the CUBIC algorithm to recalculate the
      curve so that we again start growing steeply upward from where cwnd is
      now (as CUBIC does just after a loss). Ideally we'd want the cwnd growth
      curve to be the same shape, just shifted later in time by the amount of
      the idle period.

      tcp: generate CA_EVENT_TX_START on data frames

      Issuing a CC TX_START event on control frames like pure ACK
      is a waste of time, as a CC should not care.

      Following patch needs this change, as we want CUBIC to properly track
      idle time at a low cost, with a single TX_START being generated.

      Yuchung might slightly refine the condition triggering TX_START
      on a followup patch.

      wmi: Remove private %pUL implementation

      The work performed by wmi_gtoa is equivalent to simply sprintf(out,
      "%pUL", in), so one could replace its body by this. However, most
      users feed the result directly as a %s argument to some other function
      which also understands the %p extensions (they all ultimately use
      vsnprintf), so we can eliminate some stack buffers and quite a bit of
      code by just using %pUL directly.

      In wmi_dev_uevent I'm not sure whether there's room for a
      nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
      equivalent sprintf call.

      drm/i915: Don't try to use DDR DVFS on CHV when disabled in the BIOS

      If one disables DDR DVFS in the BIOS, Punit will apparently ignores
      all DDR DVFS request. Currently we assume that DDR DVFS is always
      operational, which leads to errors in dmesg when the DDR DVFS requests
      time out.

      Fix the problem by gently prodding Punit during driver load to find out
      whether it will respond to DDR DVFS requests. If the request times out,
      we assume that DDR DVFS has been permanenly disabled in the BIOS and
      no longer perster the Punit about it.

      Btrfs: remove unnecessary locking of cleaner_mutex to avoid deadlock

      After commmit e44163e17796 ("btrfs: explictly delete unused block groups
      in close_ctree and ro-remount"), added in the 4.3 merge window, we have
      calls to btrfs_delete_unused_bgs() while holding the cleaner_mutex.
      This can cause a deadlock with a concurrent block group relocation (when
      a filesystem balance or shrink operation is in progress for example)
      because btrfs_delete_unused_bgs() locks delete_unused_bgs_mutex and the
      relocation path locks first delete_unused_bgs_mutex and then it locks
      cleaner_mutex, resulting in a classic ABBA deadlock:

               CPU 0                                        CPU 1

      lock fs_info->cleaner_mutex

                                                 __btrfs_balance() || 
btrfs_shrink_device()

      Fix this by not taking the cleaner_mutex before calling

      commit 67c5e7d464bc ("Btrfs: fix race between balance and unused block
      group deletion"). The mutex fs_info->delete_unused_bgs_mutex, the
      spinlock fs_info->unused_bgs_lock and a block group's spinlock are
      enough to get correct serialization between tasks running relocation
      and unused block group deletion (as well as between multiple tasks
      concurrently calling btrfs_delete_unused_bgs()).

      This issue was discussed (in the mailing list) during the review of
      the patch titled "btrfs: explictly delete unused block groups in
      close_ctree and ro-remount" and it was agreed that acquiring the
      cleaner mutex had to be dropped after the patch titled
      "Btrfs: fix race between balance and unused block group deletion"
      got merged (both patches were submitted at about the same time, but
      one landed in kernel 4.2 and the other in the 4.3 merge window).

      powerpc/MSI: Fix race condition in tearing down MSI interrupts

      This fixes a race which can result in the same virtual IRQ number
      being assigned to two different MSI interrupts.  The most visible
      consequence of that is usually a warning and stack trace from the
      sysfs code about an attempt to create a duplicate entry in sysfs.

      The race happens when one CPU (say CPU 0) is disposing of an MSI
      while another CPU (say CPU 1) is setting up an MSI.  CPU 0 calls
      (for example) pnv_teardown_msi_irqs(), which calls
      msi_bitmap_free_hwirqs() to indicate that the MSI (i.e. its
      hardware IRQ number) is no longer in use.  Then, before CPU 0 gets
      to calling irq_dispose_mapping() to free up the virtal IRQ number,
      CPU 1 comes in and calls msi_bitmap_alloc_hwirqs() to allocate an
      MSI, and gets the same hardware IRQ number that CPU 0 just freed.
      CPU 1 then calls irq_create_mapping() to get a virtual IRQ number,
      which sees that there is currently a mapping for that hardware IRQ
      number and returns the corresponding virtual IRQ number (which is
      the same virtual IRQ number that CPU 0 was using).  CPU 0 then
      calls irq_dispose_mapping() and frees that virtual IRQ number.
      Now, if another CPU comes along and calls irq_create_mapping(), it
      is likely to get the virtual IRQ number that was just freed,
      resulting in the same virtual IRQ number apparently being used for
      two different hardware interrupts.

      To fix this race, we just move the call to msi_bitmap_free_hwirqs()
      to after the call to irq_dispose_mapping().  Since virq_to_hw()
      doesn't work for the virtual IRQ number after irq_dispose_mapping()
      has been called, we need to call it before irq_dispose_mapping() and
      remember the result for the msi_bitmap_free_hwirqs() call.

      The pattern of calling msi_bitmap_free_hwirqs() before
      irq_dispose_mapping() appears in 5 places under arch/powerpc, and
      appears to have originated in commit 05af7bd2d75e ("[POWERPC] MPIC
      U3/U4 MSI backend") from 2007.

      netlink, mmap: fix edge-case leakages in nf queue zero-copy

      When netlink mmap on receive side is the consumer of nf queue data,
      it can happen that in some edge cases, we write skb shared info into
      the user space mmap buffer:

      Assume a possible rx ring frame size of only 4096, and the network skb,
      which is being zero-copied into the netlink skb, contains page frags
      with an overall skb->len larger than the linear part of the netlink
      skb.

      skb_zerocopy(), which is generic and thus not aware of the fact that
      shared info cannot be accessed for such skbs then tries to write and
      fill frags, thus leaking kernel data/pointers and in some corner cases
      possibly writing out of bounds of the mmap area (when filling the
      last slot in the ring buffer this way).

      I.e. the ring buffer slot is then of status NL_MMAP_STATUS_VALID, has
      an advertised length larger than 4096, where the linear part is visible
      at the slot beginning, and the leaked sizeof(struct skb_shared_info)
      has been written to the beginning of the next slot (also corrupting
      the struct nl_mmap_hdr slot header incl. status etc), since skb->end
      points to skb->data + ring->frame_size - NL_MMAP_HDRLEN.

      The fix adds and lets __netlink_alloc_skb() take the actual needed
      linear room for the network skb + meta data into account. It's completely
      irrelevant for non-mmaped netlink sockets, but in case mmap sockets
      are used, it can be decided whether the available skb_tailroom() is
      really large enough for the buffer, or whether it needs to internally
      fallback to a normal alloc_skb().

      >From nf queue side, the information whether the destination port is
      an mmap RX ring is not really available without extra port-to-socket
      lookup, thus it can only be determined in lower layers i.e. when
      __netlink_alloc_skb() is called that checks internally for this. I
      chose to add the extra ldiff parameter as mmap will then still work:
      We have data_len and hlen in nfqnl_build_packet_message(), data_len
      is the full length (capped at queue->copy_range) for skb_zerocopy()
      and hlen some possible part of data_len that needs to be copied; the
      rem_len variable indicates the needed remaining linear mmap space.

      The only other workaround in nf queue internally would be after
      allocation time by f.e. cap'ing the data_len to the skb_tailroom()
      iff we deal with an mmap skb, but that would 1) expose the fact that
      we use a mmap skb to upper layers, and 2) trim the skb where we
      otherwise could just have moved the full skb into the normal receive
      queue.

      After the patch, in my test case the ring slot doesn't fit and therefore
      shows NL_MMAP_STATUS_COPY, where a full skb carries all the data and
      thus needs to be picked up via recv().

      netlink, mmap: don't walk rx ring on poll if receive queue non-empty

      In case of netlink mmap, there can be situations where received frames
      have to be placed into the normal receive queue. The ring buffer indicates
      this through NL_MMAP_STATUS_COPY, so the user is asked to pick them up
      via recvmsg(2) syscall, and to put the slot back to NL_MMAP_STATUS_UNUSED.

      Commit 0ef707700f1c ("netlink: rx mmap: fix POLLIN condition") changed
      polling, so that we walk in the worst case the whole ring through the
      new netlink_has_valid_frame(), for example, when the ring would have no
      NL_MMAP_STATUS_VALID, but at least one NL_MMAP_STATUS_COPY frame.

      Since we do a datagram_poll() already earlier to pick up a mask that could
      possibly contain POLLIN | POLLRDNORM already (due to NL_MMAP_STATUS_COPY),
      we can skip checking the rx ring entirely.

      In case the kernel is compiled with !CONFIG_NETLINK_MMAP, then all this is
      irrelevant anyway as netlink_poll() is just defined as datagram_poll().

      net: fec: add netif status check before set mac address

      There exist one issue by below case that case system hang:
      ifconfig eth0 down
      ifconfig eth0 hw ether 00:10:19:19:81:19

      After eth0 down, all fec clocks are gated off. In the 
.fec_set_mac_address()
      function, it will set new MAC address to registers, which causes system 
hang.

      So it needs to add netif status check to avoid registers access when 
clocks are
      gated off. Until eth0 up the new MAC address are wrote into related 
registers.

      As Lucas Stach's suggestion, add a comment in the code to explain why it

      The use of get_domain() in copy_thread() results in an oops on
      ARMv7M/noMMU systems.  The thread cpu_domain value is only used when
      CONFIG_CPU_USE_DOMAINS is enabled, so there's no need to save the
      value in copy_thread() except when this is enabled, and this option
      will never be enabled on these platforms.

      net: ipv6: use common fib_default_rule_pref

      This switches IPv6 policy routing to use the shared
      fib_default_rule_pref() function of IPv4 and DECnet. It is also used in
      multicast routing for IPv4 as well as IPv6.

      The motivation for this patch is a complaint about iproute2 behaving
      inconsistent between IPv4 and IPv6 when adding policy rules: Formerly,
      IPv6 rules were assigned a fixed priority of 0x3FFF whereas for IPv4 the
      assigned priority value was decreased with each rule added.

      Since then all users of the default_pref field have been converted to
      assign the generic function fib_default_rule_pref(), fib_nl_newrule()
      may just use it directly instead. Therefore get rid of the function
      pointer altogether and make fib_default_rule_pref() static, as it's not
      used outside fib_rules.c anymore.

      ipv6: fix multipath route replace error recovery

      Problem:
      The ecmp route replace support for ipv6 in the kernel, deletes the
      existing ecmp route too early, ie when it installs the first nexthop.
      If there is an error in installing the subsequent nexthops, its too late
      to recover the already deleted existing route leaving the fib
      in an inconsistent state.

      This patch reduces the possibility of this by doing the following:
      a) Changes the existing multipath route add code to a two stage process:
        build rt6_infos + insert them
        ip6_route_add rt6_info creation code is moved into
        ip6_route_info_create.
      b) This ensures that most errors are caught during building rt6_infos
        and we fail early
      c) Separates multipath add and del code. Because add needs the special
        two stage mode in a) and delete essentially does not care.
      d) In any event if the code fails during inserting a route again, a
        warning is printed (This should be unlikely)

      Before the patch:

      global for instances where we have an actual host and remote partition 
existing,
      return the results of the private lookup.

      intel_pstate: fix PCT_TO_HWP macro

      PCT_TO_HWP does not take the actual range of pstates exported
      by HWP_CAPABILITIES in account, and is broken on most platforms.
      Remove the macro and set the min and max pstate for hwp by
      determining the range and adjusting by the min and max percent
      limits values.

      intel_pstate: Fix user input of min/max to legal policy region

      In current code, max_perf_pct might be smaller than min_perf_pct
      by improper user input:

      $ grep . /sys/devices/system/cpu/intel_pstate/m*_perf_pct
      /sys/devices/system/cpu/intel_pstate/max_perf_pct:100
      /sys/devices/system/cpu/intel_pstate/min_perf_pct:100

      $ echo 80 > /sys/devices/system/cpu/intel_pstate/max_perf_pct

      $ grep . /sys/devices/system/cpu/intel_pstate/m*_perf_pct
      /sys/devices/system/cpu/intel_pstate/max_perf_pct:80
      /sys/devices/system/cpu/intel_pstate/min_perf_pct:100

      Fix this problem by 2 steps:
       1. Normalize the user input to [min_policy, max_policy].
       2. Make sure max_perf_pct>=min_perf_pct, suggested by Seiichi Ikarashi.

      ebpf: fix fd refcount leaks related to maps in bpf syscall

      We may already have gotten a proper fd struct through fdget(), so
      whenever we return at the end of an map operation, we need to call
      fdput(). However, each map operation from syscall side first probes
      CHECK_ATTR() to verify that unused fields in the bpf_attr union are
      zero.

      In case of malformed input, we return with error, but the lookup to
      the map_fd was already performed at that time, so that we return
      without an corresponding fdput(). Fix it by performing an fdget()
      only right before bpf_map_get(). The fdget() invocation on maps in
      the verifier is not affected.

      Watchdog: Fix parent of watchdog_devices

      /sys/class/watchdog/watchdogn/device/modalias can help to identify the
      driver/module for a given watchdog node. However, many wdt devices do not
      set their parent and so, we do not see an entry for device in sysfs for
      such devices.

      This patch fixes parent of watchdog_device so that
      /sys/class/watchdog/watchdogn/device is populated.

      Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not
      have any parent. Not sure, how we can identify driver for these devices.

      watchdog: add a driver to support SAMA5D4 watchdog timer

      From SAMA5D4, the watchdog timer is upgrated with a new feature,
      which is describled as in the datasheet, "WDT_MR can be written
      until a LOCKMR command is issued in WDT_CR".
      That is to say, as long as the bootstrap and u-boot don't issue
      a LOCKMR command, WDT_MR can be written more than once in the driver.

      So the SAMA5D4 watchdog driver's implementation is different from
      the at91sam9260 watchdog driver implemented in file at91sam9_wdt.c.
      The user application open the device file to enable the watchdog timer
      hardware, and close to disable it, and set the watchdog timer timeout
      by seting WDV and WDD fields of WDT_MR register, and ping the watchdog
      by issuing WDRSTT command to WDT_CR register with hard-coded key.

      the MPC8610 one. So allow to enable the driver for MPC512x kernel
      configurations.

      watchdog: NXP LPC18xx Watchdog Timer Driver

      This commit adds support for the watchdog timer found in NXP LPC SoCs
      family, which includes LPC18xx/LPC43xx. Other SoCs in that family may
      share the same watchdog hardware.

      Watchdog driver registers a restart handler that will restart the system
      by performing an incorrect feed after ensuring the watchdog is enabled in
      reset mode.

      As watchdog cannot be disabled in hardware, driver's stop routine will
      regularly send a keepalive ping using a timer.

      watchdog: gpio-wdt: ping already at startup for always running devices

      During probe for an always-running watchdog a timer is setup to
      constantly ping the watchdog while the device is not open. The gpio to
      ping the watchdog is setup to inactive.

      For a watchdog with hw_algo = "toggle" this results in a ping depending
      on the initial state of the gpio, for hw_algo = "level" no ping is
      generated.

      Make sure that the first automatic ping is sent immediately and not only
      when the timer expires the first time. This makes the machine survive in
      case more than half of the watchdog timeout is already elapsed. (Which
      is very probable for the chip I'm faced with that has a timeout of one
      second.)

      strncmp(algo, "toggle", 6) doesn't compare the trailing '\0' byte, so
      using

        hw_algo = "toggleboggle"

      is recognized the same way as

        hw_algo = "toggle"

      . While this doesn't introduce any problems for a device tree that
      sticks to the documented settings it's still ugly.

      Fix this by using strcmp to only match on "toggle" and "level".

      xen-netback: require fewer guest Rx slots when not using GSO

      Commit f48da8b14d04ca87ffcffe68829afd45f926ec6a (xen-netback: fix
      unlimited guest Rx internal queue and carrier flapping) introduced a
      regression.

      The PV frontend in IPXE only places 4 requests on the guest Rx ring.
      Since netback required at least (MAX_SKB_FRAGS + 1) slots, IPXE could
      not receive any packets.

      a) If GSO is not enabled on the VIF, fewer guest Rx slots are required
         for the largest possible packet.  Calculate the required slots
         based on the maximum GSO size or the MTU.

         This calculation of the number of required slots relies on
         1650d5455bd2 (xen-netback: always fully coalesce guest Rx packets)
         which present in 4.0-rc1 and later.

      b) Reduce the Rx stall detection to checking for at least one
         available Rx request.  This is fine since we're predominately
         concerned with detecting interfaces which are down and thus have
         zero available Rx requests.

      fix ufs write vs readpage race when writing into a hole

      Followup to the UFS series - with the way we clear the new blocks (via
      buffer cache, possibly on more than a page worth of file) we really
      should not insert a reference to new block into inode block tree until
      after we'd cleared it.

      dax: update PMD fault handler with PMEM API

      As part of the v4.3 merge window the DAX code was updated by Matthew and
      Kirill to handle PMD pages.  Also as part of the v4.3 merge window we
      updated the DAX code to do proper PMEM flushing (commit 2765cfbb342c:
      "dax: update I/O path to do proper PMEM flushing").

      The additional code added by the DAX PMD patches also needs to be
      updated to properly use the PMEM API.  This ensures that after a PMD
      fault is handled the zeros written to the newly allocated pages are
      durable on the DIMMs.

      linux/dax.h is included to get rid of a bunch of sparse warnings.

       "This is a fairly sizeable set of changes.  I've put them through a
        decent amount of testing prior to sending the pull request due to
        that.

        There are still a few fixups that I know are coming, but I wanted to
        go ahead and get the big, sizable chunk into your hands sooner rather
        than waiting for those last few fixups.

        Of note is the fact that this creates what is intended to be a
        temporary area in the drivers/staging tree specifically for some
        cleanups and additions that are coming for the RDMA stack.  We
        deprecated two drivers (ipath and amso1100) and are waiting to hear
        back if we can deprecate another one (ehca).  We also put Intel's new
        hfi1 driver into this area because it needs to be refactored and a
        transfer library created out of the factored out code, and then it and
        the qib driver and the soft-roce driver should all be modified to use
        that library.

        I expect drivers/staging/rdma to be around for three or four kernel
        releases and then to go away as all of the work is completed and final
        deletions of deprecated drivers are done.

        Summary of changes for 4.3:

         - Create drivers/staging/rdma
         - Move amso1100 driver to staging/rdma and schedule for deletion
         - Move ipath driver to staging/rdma and schedule for deletion
         - Add hfi1 driver to staging/rdma and set TODO for move to regular
           tree
         - Initial support for namespaces to be used on RDMA devices
         - Add RoCE GID table handling to the RDMA core caching code
         - Infrastructure to support handling of devices with differing read
           and write scatter gather capabilities
         - Various iSER updates
         - Kill off unsafe usage of global mr registrations
         - Update SRP driver
         - Misc  mlx4 driver updates
         - Support for the mr_alloc verb
         - Support for a netlink interface between kernel and user space cache
           daemon to speed path record queries and route resolution
         - Ininitial support for safe hot removal of verbs devices"

      pwm: NXP LPC18xx PWM/SCT driver

      This commit adds support for NXP LPC18xx PWM/SCT.

      NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State
      Configurable Timer (SCT) which can be configured as a Pulse Width
      Modulator. Other SoCs in that family may share the same hardware.

      The PWM supports a total of 16 channels, but only 15 can be simultaneously
      requested. There's only one period, global to all the channels, thus PWM
      driver will refuse setting different values to it, unless there's only one
      channel requested.

      drm/i915: Limit the number of loops for reading a split 64bit register

      In I915_READ64_2x32 we attempt to read a 64bit register using 2 32bit
      reads. Due to the nature of the registers we try to read in this manner,
      they may increment between the two instruction (e.g. a timestamp
      counter). To keep the result accurate, we repeat the read if we detect
      an overflow (i.e. the upper value varies). However, some hardware is just
      plain flaky and may endless loop as the the upper 32bits are not stable.
      Just give up after a couple of tries and report whatever we read last.

      v2: Use the most recent values when erring out on an unstable register.

      ceph: improve readahead for file holes

      When readahead encounters file holes, osd reply returns error -ENOENT,
      finish_read() skips adding pages to the the page cache. So readahead
      does not work for file holes. The fix is adding zero pages to the
      page cache when -ENOENT is returned.

      libceph: check data_len in ->alloc_msg()

      Only ->alloc_msg() should check data_len of the incoming message
      against the preallocated ceph_msg, doing it in the messenger is not
      right.  The contract is that either ->alloc_msg() returns a ceph_msg
      which will fit all of the portions of the incoming message, or it
      returns NULL and possibly sets skip, signaling whether NULL is due to
      an -ENOMEM.  ->alloc_msg() should be the only place where we make the
      skip/no-skip decision.

      I stumbled upon this while looking at con/osd ref counting.  Right now,
      if we get a non-extent message with a larger data portion than we are
      prepared for, ->alloc_msg() returns a ceph_msg, and then, when we skip
      it in the messenger, we don't put the con/osd ref acquired in
      ceph_con_in_msg_alloc() (which is normally put in process_message()),
      so this also fixes a memory leak.

      An existing BUG_ON in ceph_msg_data_cursor_init() ensures we don't
      corrupt random memory should a buggy ->alloc_msg() return an unfit
      ceph_msg.

      While at it, I changed the "unknown tid" dout() to a pr_warn() to make
      sure all skips are seen and unified format strings.

      The issue occurs only when tipc_sk_rcv() is used to wake up postponed
      senders:

        tipc_bclink_wakeup_users()
                // wakeupq - is a queue which consists of special
                //               messages with SOCK_WAKEUP type.
                tipc_sk_rcv(wakeupq)
                        ...
                        while (skb_queue_len(inputq)) {
                                filter_rcv(skb)
                                        // Here the type of message is checked
                                        // and if it is SOCK_WAKEUP then
                                        // it tries to wake up a sender.
                                        tipc_write_space(sk)
                                                
wake_up_interruptible_sync_poll()
                        }

      After the sender thread is woke up it can gather control and perform
      an attempt to send a message. But if there is no enough place in send
      queue it will call link_schedule_user() function which puts a message
      of type SOCK_WAKEUP to the wakeup queue and put the sender to sleep.
      Thus the size of the queue actually is not changed and the while()
      loop never exits.

      The approach I proposed is to wake up only senders for which there is
      enough place in send queue so the described issue can't occur.
      Moreover the same approach is already used to wake up senders on
      unicast links.

      I have got into the issue on our product code but to reproduce the
      issue I changed a benchmark test application (from
      tipcutils/demos/benchmark) to perform the following scenario:
        1. Run 64 instances of test application (nodes). It can be done
           on the one physical machine.
        2. Each application connects to all other using TIPC sockets in
           RDM mode.
        3. When setup is done all nodes start simultaneously send
           broadcast messages.
        4. Everything hangs up.

      The issue is reproducible only when a congestion on broadcast link
      occurs. For example, when there are only 8 nodes it works fine since
      congestion doesn't occur. Send queue limit is 40 in my case (I use a
      critical importance level) and when 64 nodes send a message at the
      same moment a congestion occurs every time.

      net: dsa: bcm_sf2: Fix ageing conditions and operation

      The comparison check between cur_hw_state and hw_state is currently
      invalid because cur_hw_state is right shifted by G_MISTP_SHIFT, while
      hw_state is not, so we end-up comparing bits 2:0 with bits 7:5, which is
      going to cause an additional aging to occur. Fix this by not shifting
      cur_hw_state while reading it, but instead, mask the value with the
      appropriately shitfted bitmask.

      The other problem with the fast-ageing process is that we did not set
      the EN_AGE_DYNAMIC bit to request the ageing to occur for dynamically
      learned MAC addresses. Finally, write back 0 to the FAST_AGE_CTRL
      register to avoid leaving spurious bits sets from one operation to the
      other.

        one to the ACPI list twice and got no response, and it seems to work

           default domains from the IOMMU core in the Intel VT-d driver.

         - Fixes for a couple of DMA-API misuses in ARM IOMMU drivers, namely
           in the ARM and Tegra SMMU drivers.

         - Fix for a potential buffer overflow in the OMAP iommu driver's

      Pull regmap updates from Mark Brown:
       "This has been a busy release for regmap.

        By far the biggest set of changes here are those from Markus Pargmann
        which implement support for block transfers in smbus devices.  This
        required quite a bit of refactoring but leaves us better able to
        handle odd restrictions that controllers may have and with better
        performance on smbus.

        Other new features include:

         - Fix interactions with lockdep for nested regmaps (eg, when a device
           using regmap is connected to a bus where the bus controller has a
           separate regmap).  Lockdep's default class identification is too
           crude to work without help.

         - Support for must write bitfield operations, useful for operations
           which require writing a bit to trigger them from Kuniori Morimoto.

         - Support for delaying during register patch application from Nariman
           Poushin.

         - Support for overriding cache state via the debugfs implementation
           from Richard Fitzgerald"

      hexagon/time: Migrate to new 'set-state' interface

      Migrate hexagon driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      We weren't doing anything in the ->set_mode() callback. So, this patch
      doesn't provide any set-state callbacks.

      sb_edac: correctly fetch DIMM width on Ivy Bridge and Haswell

      dimm_dev_type has been incorrectly determined in sb_edac. This patch 
fixes it
      for Ivy Bridge and Haswell only since nothing like exists for Sandy 
Bridge.
      We tested this patch in multiple systems matching the results with the
      installed memory modules.

the

      mm: swap: zswap: maybe_preload & refactoring

      zswap_get_swap_cache_page and read_swap_cache_async have pretty much the
      same code with only significant difference in return value and usage of
      swap_readpage.

      I a helper __read_swap_cache_async() with the common code.  Behavior
      change: now zswap_get_swap_cache_page will use radix_tree_maybe_preload
      instead radix_tree_preload.  Looks like, this wasn't changed only by the
      reason of code duplication.

      zram: unify error reporting

      Make zram syslog error reporting more consistent. We have random
      error levels in some places. For example, critical errors like
        "Error allocating memory for compressed page"
      and
        "Unable to allocate temp memory"
      are reported as KERN_INFO messages.

      a) Reassign error levels

      Error messages that directly affect zram
      functionality -- pr_err():

       Error allocating zram address table
       Error creating memory pool
       Decompression failed! err=%d, page=%u
       Unable to allocate temp memory
       Compression failed! err=%d
       Error allocating memory for compressed page: %u, size=%zu
       Cannot initialise %s compressing backend
       Error allocating disk queue for device %d
       Error allocating disk structure for device %d
       Error creating sysfs group for device %d
       Unable to register zram-control class
       Unable to get major number

      Messages that do not affect functionality, but user
      must be warned (because sysfs attrs will be removed in
      this particular case) -- pr_warn():

       %d (%s) Attribute %s (and others) will be removed. %s

      Messages that do not affect functionality and mostly are
      informative -- pr_info():

       Cannot change max compression streams
       Can't change algorithm for initialized device
       Cannot change disksize for initialized device
       Added device: %s
       Removed device: %s

      b) Update sysfs_create_group() error message

      First, it lacks a trailing new line; add it.  Second, every error message
      in zram_add() has a "for device %d" part, which makes errors more
      informative.  Add missing part to "Error creating sysfs group" message.

      zsmalloc: do not take class lock in zs_shrinker_count()

      We can avoid taking class ->lock around zs_can_compact() in
      zs_shrinker_count(), because the number that we return back is outdated
      in general case, by design.  We have different sources that are able to
      change class's state right after we return from zs_can_compact() --
      ongoing I/O operations, manually triggered compaction, or two of them
      happening simultaneously.

      We re-do this calculations during compaction on a per class basis
      anyway.

      zs_unregister_shrinker() will not return until we have an active
      shrinker, so classes won't unexpectedly disappear while
      zs_shrinker_count() iterates them.

      zsmalloc: partial page ordering within a fullness_list

      We want to see more ZS_FULL pages and less ZS_ALMOST_{FULL, EMPTY}
      pages.  Put a page with higher ->inuse count first within its
      ->fullness_list, which will give us better chances to fill up this page
      with new objects (find_get_zspage() return ->fullness_list head for new
      object allocation), so some zspages will become ZS_ALMOST_FULL/ZS_FULL
      quicker.

      It performs a trivial and cheap ->inuse compare which does not slow down
      zsmalloc and in the worst case keeps the list pages in no particular
      order.

      A more expensive solution could sort fullness_list by ->inuse count.

      zsmalloc: use shrinker to trigger auto-compaction

      Perform automatic pool compaction by a shrinker when system is getting
      tight on memory.

      User-space has a very little knowledge regarding zsmalloc fragmentation
      and basically has no mechanism to tell whether compaction will result in
      any memory gain.  Another issue is that user space is not always aware
      of the fact that system is getting tight on memory.  Which leads to very
      uncomfortable scenarios when user space may start issuing compaction
      'randomly' or from crontab (for example).  Fragmentation is not always
      necessarily bad, allocated and unused objects, after all, may be filled
      with the data later, w/o the need of allocating a new zspage.  On the
      other hand, we obviously don't want to waste memory when the system
      needs it.

      Compaction now has a relatively quick pool scan so we are able to
      estimate the number of pages that will be freed easily, which makes it
      possible to call this function from a shrinker->count_objects()
      callback.  We also abort compaction as soon as we detect that we can't
      free any pages any more, preventing wasteful objects migrations.

      zsmalloc: account the number of compacted pages

      Compaction returns back to zram the number of migrated objects, which is
      quite uninformative -- we have objects of different sizes so user space
      cannot obtain any valuable data from that number.  Change compaction to
      operate in terms of pages and return back to compaction issuer the
      number of pages that were freed during compaction.  So from now on we
      will export more meaningful value in zram<id>/mm_stat -- the number of
      freed (compacted) pages.

      This requires:
       (a) a rename of `num_migrated' to 'pages_compacted'
       (b) a internal API change -- return first_page's fullness_group from
           putback_zspage(), so we know when putback_zspage() did
           free_zspage().  It helps us to account compaction stats correctly.

      zsmalloc/zram: introduce zs_pool_stats api

      `zs_compact_control' accounts the number of migrated objects but it has
      a limited lifespan -- we lose it as soon as zs_compaction() returns back
      to zram.  It worked fine, because (a) zram had it's own counter of
      migrated objects and (b) only zram could trigger compaction.  However,
      this does not work for automatic pool compaction (not issued by zram).
      To account objects migrated during auto-compaction (issued by the
      shrinker) we need to store this number in zs_pool.

      Define a new `struct zs_pool_stats' structure to keep zs_pool's stats
      there.  It provides only `num_migrated', as of this writing, but it
      surely can be extended.

      A new zsmalloc zs_pool_stats() symbol exports zs_pool's stats back to
      caller.

      Use zs_pool_stats() in zram and remove `num_migrated' from zram_stats.

      zsmalloc: always keep per-class stats

      Always account per-class `zs_size_stat' stats.  This data will help us
      make better decisions during compaction.  We are especially interested
      in OBJ_ALLOCATED and OBJ_USED, which can tell us if class compaction
      will result in any memory gain.

      For instance, we know the number of allocated objects in the class, the
      number of objects being used (so we also know how many objects are not
      used) and the number of objects per-page.  So we can ensure if we have
      enough unused objects to form at least one ZS_EMPTY zspage during
      compaction.

      We calculate this value on per-class basis so we can calculate a total
      number of zspages that can be released.  Which is exactly what a
      shrinker wants to know.

      zsmalloc: drop unused variable `nr_to_migrate'

      This patchset tweaks compaction and makes it possible to trigger pool
      compaction automatically when system is getting low on memory.

      zsmalloc in some cases can suffer from a notable fragmentation and
      compaction can release some considerable amount of memory.  The problem
      here is that currently we fully rely on user space to perform compaction
      when needed.  However, performing zsmalloc compaction is not always an
      obvious thing to do.  For example, suppose we have a `idle' fragmented
      (compaction was never performed) zram device and system is getting low
      on memory due to some 3rd party user processes (gcc LTO, or firefox,
      etc.).  It's quite unlikely that user space will issue zpool compaction
      in this case.  Besides, user space cannot tell for sure how badly pool
      is fragmented; however, this info is known to zsmalloc and, hence, to a
      shrinker.

      This patch (of 7):

      __zs_compact() does not use `nr_to_migrate', drop it.

      mm/page_alloc.c: change sysctl_lower_zone_reserve_ratio to 
sysctl_lowmem_reserve_ratio in comments

      We use sysctl_lowmem_reserve_ratio rather than
      sysctl_lower_zone_reserve_ratio to determine how aggressive the kernel
      is in defending lowmem from the possibility of being captured into
      pinned user memory.  To avoid misleading, correct it in some comments.

      mm/khugepaged: allow interruption of allocation sleep again

      Commit 1dfb059b9438 ("thp: reduce khugepaged freezing latency") fixed
      khugepaged to do not block a system suspend.  But the result is that it
      could not get interrupted before the given timeout because the condition
      for the wait event is "false".

      This patch puts back the original approach but it uses
      freezable_schedule_timeout_interruptible() instead of
      schedule_timeout_interruptible().  It does the right thing.  I am pretty
      sure that the freezable variant was not used in the original fix only
      because it was not available at that time.

      The regression has been there for ages.  It was not critical.  It just
      did the allocation throttling a little bit more aggressively.

      I found this problem when converting the kthread to kthread worker API
      and trying to understand the code.

      This bug is thought to have minimal userspace-visible impact.  Somebody
      could set a high alloc_sleep value by mistake, and then try to fix it
      back, but khugepaged would keep sleeping until the high value expires.

      mm/compaction: correct to flush migrated pages if pageblock skip happens

      We cache isolate_start_pfn before entering isolate_migratepages().  If
      pageblock is skipped in isolate_migratepages() due to whatever reason,
      cc->migrate_pfn can be far from isolate_start_pfn hence we flush pages
      that were freed.  For example, the following scenario can be possible:

      - assume order-9 compaction, pageblock order is 9
      - start_isolate_pfn is 0x200
      - isolate_migratepages()
        - skip a number of pageblocks
        - start to isolate from pfn 0x600
        - cc->migrate_pfn = 0x620
        - return
      - last_migrated_pfn is set to 0x200
      - check flushing condition
        - current_block_start is set to 0x600
        - last_migrated_pfn < current_block_start then do useless flush

      This wrong flush would not help the performance and success rate so this
      patch tries to fix it.  One simple way to know the exact position where
      we start to isolate migratable pages is that we cache it in
      isolate_migratepages() before entering actual isolation.  This patch
      implements that and fixes the problem.

      mm: use numa_mem_id() in alloc_pages_node()

      alloc_pages_node() might fail when called with NUMA_NO_NODE and
      __GFP_THISNODE on a CPU belonging to a memoryless node.  To make the
      local-node fallback more robust and prevent such situations, use
      numa_mem_id(), which was introduced for similar scenarios in the slab
      context.

      mm: unify checks in alloc_pages_node() and __alloc_pages_node()

      Perform the same debug checks in alloc_pages_node() as are done in
      __alloc_pages_node(), by making the former function a wrapper of the
      latter one.

      In addition to better diagnostics in DEBUG_VM builds for situations
      which have been already fatal (e.g.  out-of-bounds node id), there are
      two visible changes for potential existing buggy callers of
      alloc_pages_node():

      - calling alloc_pages_node() with any negative nid (e.g. due to arithmetic
        overflow) was treated as passing NUMA_NO_NODE and fallback to local 
node was
        applied. This will now be fatal.
      - calling alloc_pages_node() with an offline node will now be checked for
        DEBUG_VM builds. Since it's not fatal if the node has been previously 
online,
        and this patch may expose some existing buggy callers, change the 
VM_BUG_ON
        in __alloc_pages_node() to VM_WARN_ON.

      mm: rename alloc_pages_exact_node() to __alloc_pages_node()

      alloc_pages_exact_node() was introduced in commit 6484eb3e2a81 ("page
      allocator: do not check NUMA node ID when the caller knows the node is
      valid") as an optimized variant of alloc_pages_node(), that doesn't
      fallback to current node for nid == NUMA_NO_NODE.  Unfortunately the
      name of the function can easily suggest that the allocation is
      restricted to the given node and fails otherwise.  In truth, the node is
      only preferred, unless __GFP_THISNODE is passed among the gfp flags.

      The misleading name has lead to mistakes in the past, see for example
      commits 5265047ac301 ("mm, thp: really limit transparent hugepage
      allocation to local node") and b360edb43f8e ("mm, mempolicy:
      migrate_to_node should only migrate to node").

      Another issue with the name is that there's a family of
      alloc_pages_exact*() functions where 'exact' means exact size (instead
      of page order), which leads to more confusion.

      To prevent further mistakes, this patch effectively renames
      alloc_pages_exact_node() to __alloc_pages_node() to better convey that
      it's an optimized variant of alloc_pages_node() not intended for general
      usage.  Both functions get described in comments.

      It has been also considered to really provide a convenience function for
      allocations restricted to a node, but the major opinion seems to be that
      __GFP_THISNODE already provides that functionality and we shouldn't
      duplicate the API needlessly.  The number of users would be small
      anyway.

      Existing callers of alloc_pages_exact_node() are simply converted to
      call __alloc_pages_node(), with the exception of sba_alloc_coherent()
      which open-codes the check for NUMA_NO_NODE, so it is converted to use
      alloc_pages_node() instead.  This means it no longer performs some
      VM_BUG_ON checks, and since the current check for nid in
      alloc_pages_node() uses a 'nid < 0' comparison (which includes
      NUMA_NO_NODE), it may hide wrong values which would be previously
      exposed.

      Both differences will be rectified by the next patch.

      To sum up, this patch makes no functional changes, except temporarily
      hiding potentially buggy callers.  Restricting the checks in
      alloc_pages_node() is left for the next patch which can in turn expose
      more existing buggy callers.

      shmem: recalculate file inode when fstat

      Shmem uses shmem_recalc_inode to update i_blocks when it allocates page,
      undoes range or swaps.  But mm can drop clean page without notifying
      shmem.  This makes fstat sometimes return out-of-date block size.

      The problem can be partially solved when we add
      inode_operations->getattr which calls shmem_recalc_inode to update
      i_blocks for fstat.

      shmem_recalc_inode also updates counter used by statfs and
      vm_committed_as.  For them the situation is not changed.  They still
      suffer from the discrepancy after dropping clean page and before the
      function is called by aforementioned triggers.

      mm/hwpoison: don't try to unpoison containment-failed pages

      memory_failure() can be called at any page at any time, which means that
      we can't eliminate the possibility of containment failure.  In such case
      the best option is to leak the page intentionally (and never touch it
      later.)

      We have an unpoison function for testing, and it cannot handle such
      containment-failed pages, which results in kernel panic (visible with
      various calltraces.) So this patch suggests that we limit the
      unpoisonable pages to properly contained pages and ignore any other
      ones.

      Testers are recommended to keep in mind that there're un-unpoisonable
      pages when writing test programs.

        __soft_offline_page
        TestSetPageHWPoison
                              unpoison_memory
                              PageHWPoison check (true)
                              TestClearPageHWPoison
                              put_page    -> release refcount held by 
get_hwpoison_page in unpoison_memory
                              put_page    -> release refcount held by 
isolate_lru_page in __soft_offline_page
        migrate_pages

      The second put_page() releases refcount held by isolate_lru_page() which
      will lead to unmap_and_move() releases the last refcount of page and w/
      mapcount still 1 since try_to_unmap() is not called if there is only one
      user map the page.  Anyway, the page refcount and mapcount will still
      mess if the page is mapped by multiple users.

      This race was introduced by commit 4491f71260 ("mm/memory-failure: set
      PageHWPoison before migrate_pages()"), which focuses on preventing the
      reuse of successfully migrated page.  Before this commit we prevent the
      reuse by changing the migratetype to MIGRATE_ISOLATE during soft
      offlining, which has the following problems, so simply reverting the
      commit is not a best option:

        1) it doesn't eliminate the reuse completely, because
           set_migratetype_isolate() can fail to set MIGRATE_ISOLATE to the
           target page if the pageblock of the page contains one or more
           unmovable pages (i.e.  has_unmovable_pages() returns true).

        2) the original code changes migratetype to MIGRATE_ISOLATE
           forcibly, and sets it to MIGRATE_MOVABLE forcibly after soft offline,
           regardless of the original migratetype state, which could impact
           other subsystems like memory hotplug or compaction.

      This patch moves PageSetHWPoison just after put_page() in
      unmap_and_move(), which closes up the reported race window and minimizes
      another race window b/w SetPageHWPoison and reallocation (which causes
      the reuse of soft-offlined page.) The latter race window still exists
      but it's acceptable, because it's rare and effectively the same as
      ordinary "containment failure" case even if it happens, so keep the
      window open is acceptable.

      mm/hwpoison: fix refcount of THP head page in no-injection case

      Hwpoison injection takes a refcount of target page and another refcount
      of head page of THP if the target page is the tail page of a THP.
      However, current code doesn't release the refcount of head page if the
      THP is not supported to be injected wrt hwpoison filter.

      Fix it by reducing the refcount of head page if the target page is the
      tail page of a THP and it is not supported to be injected.

      arm64: support initrd outside kernel linear map

      The use of mem= could leave part or all of the initrd outside of the
      kernel linear map.  This will lead to an error when unpacking the initrd

      relocates the initrd to be fully within the linear map.

      mm: add utility for early copy from unmapped ram

      When booting an arm64 kernel w/initrd using UEFI/grub, use of mem= will
      likely cut off part or all of the initrd.  This leaves it outside the
      kernel linear map which leads to failure when unpacking.  The x86 code
      has a similar need to relocate an initrd outside of mapped memory in
      some cases.

      The current x86 code uses early_memremap() to copy the original initrd
      from unmapped to mapped RAM.  This patchset creates a generic
      copy_from_early_mem() utility based on that x86 code and has arm64 and
      x86 share it in their respective initrd relocation code.

      This patch (of 3):

      In some early boot circumstances, it may be necessary to copy from RAM
      outside the kernel linear mapping to mapped RAM.  The need to relocate
      an initrd is one example in the x86 code.  This patch creates a helper
      function based on current x86 code.

      mm, compaction: skip compound pages by order in free scanner

      The compaction free scanner is looking for PageBuddy() pages and
      skipping all others.  For large compound pages such as THP or hugetlbfs,
      we can save a lot of iterations if we skip them at once using their
      compound_order().  This is generally unsafe and we can read a bogus
      value of order due to a race, but if we are careful, the only danger is
      skipping too much.

      When tested with stress-highalloc from mmtests on 4GB system with 1GB
      hugetlbfs pages, the vmstat compact_free_scanned count decreased by at
      least 15%.

      mm, compaction: always skip all compound pages by order in migrate scanner

      The compaction migrate scanner tries to skip THP pages by their order,
      to reduce number of iterations for pages it cannot isolate.  The check
      is only done if PageLRU() is true, which means it applies to THP pages,
      but not e.g.  hugetlbfs pages or any other non-LRU compound pages, which
      we have to iterate by base pages.

      This limitation comes from the assumption that it's only safe to read
      compound_order() when we have the zone's lru_lock and THP cannot be
      split under us.  But the only danger (after filtering out order values
      that are not below MAX_ORDER, to prevent overflows) is that we skip too
      much or too little after reading a bogus compound_order() due to a rare
      race.  This is the same reasoning as patch 99c0fd5e51c4 ("mm,
      compaction: skip buddy pages by their order in the migrate scanner")
      introduced for unsafely reading PageBuddy() order.

      After this patch, all pages are tested for PageCompound() and we skip
      them by compound_order().  The test is done after the test for
      balloon_page_movable() as we don't want to assume if balloon pages (or
      other pages with own isolation and migration implementation if a generic
      API gets implemented) are compound or not.

      When tested with stress-highalloc from mmtests on 4GB system with 1GB
      hugetlbfs pages, the vmstat compact_migrate_scanned count decreased by
      15%.

      mm, compaction: simplify handling restart position in free pages scanner

      Handling the position where compaction free scanner should restart
      (stored in cc->free_pfn) got more complex with commit e14c720efdd7 ("mm,
      compaction: remember position within pageblock in free pages scanner").
      Currently the position is updated in each loop iteration of
      isolate_freepages(), although it should be enough to update it only when
      breaking from the loop.  There's also an extra check outside the loop
      updates the position in case we have met the migration scanner.

      This can be simplified if we move the test for having isolated enough
      from the for-loop header next to the test for contention, and
      determining the restart position only in these cases.  We can reuse the
      isolate_start_pfn variable for this instead of setting cc->free_pfn
      directly.  Outside the loop, we can simply set cc->free_pfn to current
      value of isolate_start_pfn without any extra check.

      Also add a VM_BUG_ON to catch possible mistake in the future, in case we
      later add a new condition that terminates isolate_freepages_block()
      prematurely without also considering the condition in
      isolate_freepages().

      mm, compaction: more robust check for scanners meeting

      Assorted compaction cleanups and optimizations.  The interesting patches
      are 4 and 5.  In 4, skipping of compound pages in single iteration is
      improved for migration scanner, so it works also for !PageLRU compound
      pages such as hugetlbfs, slab etc.  Patch 5 introduces this kind of
      skipping in the free scanner.  The trick is that we can read
      compound_order() without any protection, if we are careful to filter out
      values larger than MAX_ORDER.  The only danger is that we skip too much.
      The same trick was already used for reading the freepage order in the
      migrate scanner.

      To demonstrate improvements of Patches 4 and 5 I've run stress-highalloc
      from mmtests, set to simulate THP allocations (including __GFP_COMP) on
      a 4GB system where 1GB was occupied by hugetlbfs pages.  I'll include
      just the relevant stats:

                                     Patch 3     Patch 4     Patch 5

      Compaction stalls                 7523        7529        7515
      Compaction success                 323         304         322
      Compaction failures               7200        7224        7192
      Page migrate success            247778      264395      240737
      Page migrate failure             15358       33184       21621
      Compaction pages isolated       906928      980192      909983
      Compaction migrate scanned     2005277     1692805     1498800
      Compaction free scanned       13255284    11539986     9011276
      Compaction cost                    288         305         277

      With 5 iterations per patch, the results are still noisy, but we can see
      that Patch 4 does reduce migrate_scanned by 15% thanks to skipping the
      hugetlbfs pages at once.  Interestingly, free_scanned is also reduced
      and I have no idea why.  Patch 5 further reduces free_scanned as
      expected, by 15%.  Other stats are unaffected modulo noise.

      [1] https://lkml.org/lkml/2015/1/19/158

      This patch (of 5):

      Compaction should finish when the migration and free scanner meet, i.e.
      they reach the same pageblock.  Currently however, the test in
      compact_finished() simply just compares the exact pfns, which may yield
      a false negative when the free scanner position is in the middle of a
      pageblock and the migration scanner reaches the begining of the same
      pageblock.

      This hasn't been a problem until commit e14c720efdd7 ("mm, compaction:
      remember position within pageblock in free pages scanner") allowed the
      free scanner position to be in the middle of a pageblock between
      invocations.  The hot-fix 1d5bfe1ffb5b ("mm, compaction: prevent
      infinite loop in compact_zone") prevented the issue by adding a special
      check in the migration scanner to satisfy the current detection of
      scanners meeting.

      However, the proper fix is to make the detection more robust.  This
      patch introduces the compact_scanners_met() function that returns true
      when the free scanner position is in the same or lower pageblock than
      the migration scanner.  The special case in isolate_migratepages()
      introduced by 1d5bfe1ffb5b is removed.

      mm: add support for __GFP_ZERO flag to dma_pool_alloc()

      Currently a call to dma_pool_alloc() with a ___GFP_ZERO flag returns a
      non-zeroed memory region.

      This patchset adds support for the __GFP_ZERO flag to dma_pool_alloc(),
      adds 2 wrapper functions for allocing zeroed memory from a pool, and
      provides a coccinelle script for finding & replacing instances of
      dma_pool_alloc() followed by memset(0) with a single dma_pool_zalloc()
      call.

      There was some concern that this always calls memset() to zero, instead
      of passing __GFP_ZERO into the page allocator.
      [https://lkml.org/lkml/2015/7/15/881]

      I ran a test on my system to get an idea of how often dma_pool_alloc()
      calls into pool_alloc_page().

      After Boot:       [   30.119863] alloc_calls:541, page_allocs:7
      After an hour:    [ 3600.951031] alloc_calls:9566, page_allocs:12
      After copying 1GB file onto a USB drive:
                [ 4260.657148] alloc_calls:17225, page_allocs:12

      It doesn't look like dma_pool_alloc() calls down to the page allocator
      very often (at least on my system).

      This patch (of 4):

      Currently the __GFP_ZERO flag is ignored by dma_pool_alloc().
      Make dma_pool_alloc() zero the memory if this flag is set.

      vmscan: fix increasing nr_isolated incurred by putback unevictable pages

      reclaim_clean_pages_from_list() assumes that shrink_page_list() returns
      number of pages removed from the candidate list.  But shrink_page_list()
      puts back mlocked pages without passing it to caller and without
      counting as nr_reclaimed.  This increases nr_isolated.

      To fix this, this patch changes shrink_page_list() to pass unevictable
      pages back to caller.  Caller will take care those pages.

      Minchan said:

      It fixes two issues.

      1. With unevictable page, cma_alloc will be successful.

      Exactly speaking, cma_alloc of current kernel will fail due to
      unevictable pages.

      2. fix leaking of NR_ISOLATED counter of vmstat

      With it, too_many_isolated works.  Otherwise, it could make hang until
      the process get SIGKILL.

      mm: vmscan: never isolate more pages than necessary

      If transparent huge pages are enabled, we can isolate many more pages
      than we actually need to scan, because we count both single and huge
      pages equally in isolate_lru_pages().

      Since commit 5bc7b8aca942d ("mm: thp: add split tail pages to shrink
      page list in page reclaim"), we scan all the tail pages immediately
      after a huge page split (see shrink_page_list()).  As a result, we can
      reclaim up to SWAP_CLUSTER_MAX * HPAGE_PMD_NR (512 MB) in one run!

      This is easy to catch on memcg reclaim with zswap enabled.  The latter
      makes swapout instant so that if we happen to scan an unreferenced huge
      page we will evict both its head and tail pages immediately, which is
      likely to result in excessive reclaim.

      bootmem: avoid freeing to bootmem after bootmem is done

      Bootmem isn't popular any more, but some architectures still use it, and
      freeing to bootmem after calling free_all_bootmem_core() can end up
      scribbling over random memory.  Instead, make sure the kernel generates
      a warning in this case by ensuring the node_bootmem_map field is
      non-NULL when are freeing or marking bootmem.

      An instance of this bug was just fixed in the tile architecture ("tile:
      use free_bootmem_late() for initrd") and catching this case more widely
      seems like a good thing.

      mem-hotplug: handle node hole when initializing numa_meminfo.

      When parsing SRAT, all memory ranges are added into numa_meminfo.  In
      numa_init(), before entering numa_cleanup_meminfo(), all possible memory
      ranges are in numa_meminfo.  And numa_cleanup_meminfo() removes all
      ranges over max_pfn or empty.

      But, this only works if the nodes are continuous.  Let's have a look at
      the following example:

      We have an SRAT like this:
      SRAT: Node 0 PXM 0 [mem 0x00000000-0x5fffffff]
      SRAT: Node 0 PXM 0 [mem 0x100000000-0x1ffffffffff]
      SRAT: Node 1 PXM 1 [mem 0x20000000000-0x3ffffffffff]
      SRAT: Node 4 PXM 2 [mem 0x40000000000-0x5ffffffffff] hotplug
      SRAT: Node 5 PXM 3 [mem 0x60000000000-0x7ffffffffff] hotplug
      SRAT: Node 2 PXM 4 [mem 0x80000000000-0x9ffffffffff] hotplug
      SRAT: Node 3 PXM 5 [mem 0xa0000000000-0xbffffffffff] hotplug
      SRAT: Node 6 PXM 6 [mem 0xc0000000000-0xdffffffffff] hotplug
      SRAT: Node 7 PXM 7 [mem 0xe0000000000-0xfffffffffff] hotplug

      On boot, only node 0,1,2,3 exist.

      And the numa_meminfo will look like this:
      numa_meminfo.nr_blks = 9
      1. on node 0: [0, 60000000]
      2. on node 0: [100000000, 20000000000]
      3. on node 1: [20000000000, 40000000000]
      4. on node 4: [40000000000, 60000000000]
      5. on node 5: [60000000000, 80000000000]
      6. on node 2: [80000000000, a0000000000]
      7. on node 3: [a0000000000, a0800000000]
      8. on node 6: [c0000000000, a0800000000]
      9. on node 7: [e0000000000, a0800000000]

      And numa_cleanup_meminfo() will merge 1 and 2, and remove 8,9 because the
      end address is over max_pfn, which is a0800000000.  But 4 and 5 are not
      removed because their end addresses are less then max_pfn.  But in fact,
      node 4 and 5 don't exist.

      In a word, numa_cleanup_meminfo() is not able to handle holes between 
nodes.

      Since memory ranges in node 4 and 5 are in numa_meminfo, in
      numa_register_memblks(), node 4 and 5 will be mistakenly set to online.

      If you run lscpu, it will show:
      NUMA node0 CPU(s):     0-14,128-142
      NUMA node1 CPU(s):     15-29,143-157
      NUMA node2 CPU(s):

      memblock_overlaps_region() checks if the given memblock region
      intersects a region in memblock.  If so, it returns the index of the
      intersected region.

      But its only caller is memblock_is_region_reserved(), and it returns 0

      Both of these should return bool.

      hugetlbfs: add hugetlbfs_fallocate()

      This is based on the shmem version, but it has diverged quite a bit.  We
      have no swap to worry about, nor the new file sealing.  Add
      synchronication via the fault mutex table to coordinate page faults,
      fallocate allocation and fallocate hole punch.

      What this allows us to do is move physical memory in and out of a
      hugetlbfs file without having it mapped.  This also gives us the ability
      to support MADV_REMOVE since it is currently implemented using
      fallocate().  MADV_REMOVE lets madvise() remove pages from the middle of
      a hugetlbfs file, which wasn't possible before.

      hugetlbfs fallocate only operates on whole huge pages.

      Based on code by Dave Hansen.

      In vma_has_reserves(), the current assumption is that reserves are
      always present for shared mappings.  However, this will not be the case

      reservation).  vma_has_reserves is passed "chg" which indicates whether
      or not a region/reserve map is present.  Use this to determine if
      reserves are actually present or were removed via hole punch.

      hugetlbfs: truncate_hugepages() takes a range of pages

      Modify truncate_hugepages() to take a range of pages (start, end)
      instead of simply start.  If an end value of LLONG_MAX is passed, the
      current "truncate" functionality is maintained.  Existing callers are
      modified to pass LLONG_MAX as end of range.  By keying off end ==
      LLONG_MAX, the routine behaves differently for truncate and hole punch.
      Page removal is now synchronized with page allocation via faults by
      using the fault mutex table.  The hole punch case can experience the
      rare region_del error and must handle accordingly.

      Add the routine hugetlb_fix_reserve_counts to fix up reserve counts in
      the case where region_del returns an error.

      Since the routine handles more than just the truncate case, it is
      renamed to remove_inode_hugepages().  To be consistent, the routine
      truncate_huge_page() is renamed remove_huge_page().

      Downstream of remove_inode_hugepages(), the routine
      hugetlb_unreserve_pages() is also modified to take a range of pages.
      hugetlb_unreserve_pages is modified to detect an error from region_del and
      pass it back to the caller.

      mm/hugetlb: add region_del() to delete a specific range of entries

      fallocate hole punch will want to remove a specific range of pages.  The
      existing region_truncate() routine deletes all region/reserve map
      entries after a specified offset.  region_del() will provide this same
      functionality if the end of region is specified as LONG_MAX.  Hence,
      region_del() can replace region_truncate().

      Unlike region_truncate(), region_del() can return an error in the rare
      case where it can not allocate memory for a region descriptor.  This
      ONLY happens in the case where an existing region must be split.
      Current callers passing LONG_MAX as end of range will never experience
      this error and do not need to deal with error handling.  Future callers
      of region_del() (such as fallocate hole punch) will need to handle this
      error.

      mm/hugetlb: add cache of descriptors to resv_map for region_add

      hugetlbfs is used today by applications that want a high degree of
      control over huge page usage.  Often, large hugetlbfs files are used to
      map a large number huge pages into the application processes.  The
      applications know when page ranges within these large files will no
      longer be used, and ideally would like to release them back to the
      subpool or global pools for other uses.  The fallocate() system call
      provides an interface for preallocation and hole punching within files.
      This patch set adds fallocate functionality to hugetlbfs.

      fallocate hole punch will want to remove a specific range of pages.
      When pages are removed, their associated entries in the region/reserve
      map will also be removed.  This will break an assumption in the
      region_chg/region_add calling sequence.  If a new region descriptor must
      be allocated, it is done as part of the region_chg processing.  In this
      way, region_add can not fail because it does not need to attempt an
      allocation.

      To prepare for fallocate hole punch, create a "cache" of descriptors
      that can be used by region_add if necessary.  region_chg will ensure
      there are sufficient entries in the cache.  It will be necessary to
      track the number of in progress add operations to know a sufficient
      number of descriptors reside in the cache.  A new routine region_abort
      is added to adjust this in progress count when add operations are
      aborted.  vma_abort_reservation is also added for callers creating
      reservations with vma_needs_reservation/vma_commit_reservation.

      mm: rename and move get/set_freepage_migratetype

      The pair of get/set_freepage_migratetype() functions are used to cache
      pageblock migratetype for a page put on a pcplist, so that it does not
      have to be retrieved again when the page is put on a free list (e.g.
      when pcplists become full).  Historically it was also assumed that the
      value is accurate for pages on freelists (as the functions' names
      unfortunately suggest), but that cannot be guaranteed without affecting
      various allocator fast paths.  It is in fact not needed and all such
      uses have been removed.

      The last remaining (but pointless) usage related to pages of freelists
      is in move_freepages(), which this patch removes.

      To prevent further confusion, rename the functions to
      get/set_pcppage_migratetype() and expand their description.  Since all
      the users are now in mm/page_alloc.c, move the functions there from the
      shared header.

      mm, page_isolation: remove bogus tests for isolated pages

      The __test_page_isolated_in_pageblock() is used to verify whether all
      pages in pageblock were either successfully isolated, or are hwpoisoned.
      Two of the possible state of pages, that are tested, are however bogus
      and misleading.

      Both tests rely on get_freepage_migratetype(page), which however has no
      guarantees about pages on freelists.  Specifically, it doesn't guarantee
      that the migratetype returned by the function actually matches the
      migratetype of the freelist that the page is on.  Such guarantee is not
      its purpose and would have negative impact on allocator performance.

      The first test checks whether the freepage_migratetype equals
      MIGRATE_ISOLATE, supposedly to catch races between page isolation and
      allocator activity.  These races should be fixed nowadays with
      51bb1a4093 ("mm/page_alloc: add freepage on isolate pageblock to correct
      buddy list") and related patches.  As explained above, the check
      wouldn't be able to catch them reliably anyway.  For the same reason
      false positives can happen, although they are harmless, as the
      move_freepages() call would just move the page to the same freelist it's
      already on.  So removing the test is not a bug fix, just cleanup.  After
      this patch, we assume that all PageBuddy pages are on the correct
      freelist and that the races were really fixed.  A truly reliable
      verification in the form of e.g.  VM_BUG_ON() would be complicated and
      is arguably not needed.

      The second test (page_count(page) == 0 && get_freepage_migratetype(page)
      == MIGRATE_ISOLATE) is probably supposed (the code comes from a big
      memory isolation patch from 2007) to catch pages on MIGRATE_ISOLATE
      pcplists.  However, pcplists don't contain MIGRATE_ISOLATE freepages
      nowadays, those are freed directly to free lists, so the check is
      obsolete.  Remove it as well.

      lib/show_mem.c: correct reserved memory calculation

      CMA reserved memory is not part of total reserved memory.  Currently
      when we print the total reserve memory it considers cma as part of
      reserve memory and do minus of totalcma_pages from reserved, which is
      wrong.  In cases where total reserved is less than cma reserved we will
      get negative values & while printing we print as unsigned and we will
      get a very large value.

      Below is the show mem output on X86 ubuntu based system where CMA
      reserved is 100MB (25600 pages) & total reserved is ~40MB(10316 pages).
      And reserve memory shows a large value because of this bug.

      Before:
      [  127.066430] 898908 pages RAM

      memcg, tcp_kmem: check for cg_proto in sock_update_memcg

      sk_prot->proto_cgroup is allowed to return NULL but sock_update_memcg
      doesn't check for NULL.  The function relies on the mem_cgroup_is_root
      check because we shouldn't get NULL otherwise because mem_cgroup_from_task
      will always return !NULL.

      All other callers are checking for NULL and we can safely replace
      mem_cgroup_is_root() check by cg_proto != NULL which will be more
      straightforward (proto_cgroup returns NULL for the root memcg already).

      memcg: export struct mem_cgroup

      mem_cgroup structure is defined in mm/memcontrol.c currently which means
      that the code outside of this file has to use external API even for
      trivial access stuff.

      This patch exports mm_struct with its dependencies and makes some of the
      exported functions inlines.  This even helps to reduce the code size a bit
      (make defconfig + CONFIG_MEMCG=y)

        text            data    bss     dec              hex    filename

      This is not much (370B) but better than nothing.

      We also save a function call in some hot paths like callers of
      mem_cgroup_count_vm_event which is used for accounting.

      The patch doesn't introduce any functional changes.

      sparc32: do not include swap.h from pgtable_32.h

      "memcg: export struct mem_cgroup" will add includes into
      linux/memcontrol.h which lead to further header dependency issues as
      reported by Guenter Roeck:

        In file included from include/linux/highmem.h:7:0,
                         from include/linux/bio.h:23,
                         from include/linux/writeback.h:192,
                         from include/linux/memcontrol.h:30,
                         from include/linux/swap.h:8,
                         from ./arch/sparc/include/asm/pgtable_32.h:17,
                         from ./arch/sparc/include/asm/pgtable.h:6,
                         from arch/sparc/kernel/traps_32.c:23:
        include/linux/mm.h: In function 'is_vmalloc_addr':
        include/linux/mm.h:371:17: error: 'VMALLOC_START' undeclared (first use 
in this function)
        include/linux/mm.h:371:17: note: each undeclared identifier is reported 
only once for each function it appears in
        include/linux/mm.h:371:41: error: 'VMALLOC_END' undeclared (first use

        include/linux/mm.h: In function 'maybe_mkwrite':
        include/linux/mm.h:556:3: error: implicit declaration of function 
'pte_mkwrite'

      The issue is that pgtable_32.h depends on swap.h to get swap_entry_t but
      that goes all the way down to linux/mm.h which wants to have VMALLOC_*
      which is defined later in pgtable_32.h, though.

      swap_entry_t is defined in include/mm_types.h so it should be sufficient
      to include this header without more dependencies.

      instead of before in a hot one.

      I have a little microbenchmark that does repeated, small writes to tmpfs.
      This patch speeds that micro up by 6.2%.

      === Long version ===

      When doing a sys_write() we have a source buffer in userspace and then a
      target file page.

      If both of those are the same physical page, there is a potential deadlock
      that we avoid.  It would happen something like this:

      1. We start the write to the file
      2. Allocate page cache page and set it !Uptodate
      3. Touch the userspace buffer to copy in the user data
      4. Page fault (since source of the write not yet mapped)
      5. Page fault code tries to lock the page and deadlocks

      (more details on this below)

      To avoid this, we prefault the page to guarantee that this fault does not
      occur.  But, this prefault comes at a cost.  It is one of the most
      expensive things that we do in a hot write() path (especially if we
      compare it to the read path).  It is working around a pretty rare case.

      To fix this, it's pretty simple.  We move the "prefault" code to run after
      we attempt the copy.  We explicitly disable page faults _during_ the copy,
      detect the copy failure, then execute the "prefault" ouside of where the
      page lock needs to be held.

      iov_iter_copy_from_user_atomic() actually already has an implicit
      pagefault_disable() inside of it (at least on x86), but we add an explicit
      one.  I don't think we can depend on every kmap_atomic() implementation to
      pagefault_disable() for eternity.

      ===================================================

      The stack trace when this happens looks like this:

        wait_on_page_bit_killable+0xc0/0xd0
        __lock_page_or_retry+0x84/0xa0
        filemap_fault+0x1ed/0x3d0

        do_page_fault+0xc/0x10
        page_fault+0x22/0x30
        generic_perform_write+0xca/0x1a0
        __generic_file_write_iter+0x190/0x1f0
        ext4_file_write_iter+0xe9/0x460
        __vfs_write+0xaa/0xe0
        vfs_write+0xa6/0x1a0
        SyS_write+0x46/0xa0
        entry_SYSCALL_64_fastpath+0x12/0x6a
        0xffffffffffffffff

      (Note, this does *NOT* happen in practice today because
       the kmap_atomic() does a pagefault_disable().  The trace
       above was obtained by taking out the pagefault_disable().)

      You can trigger the deadlock with this little code snippet:

        fd = open("foo", O_RDWR);
        fdmap = mmap(NULL, len, PROT_WRITE|PROT_READ, MAP_SHARED, fd, 0);
        write(fd, &fdmap[0], 1);

      mm: /proc/pid/smaps:: show proportional swap share of the mapping

      We want to know per-process workingset size for smart memory management
      on userland and we use swap(ex, zram) heavily to maximize memory
      efficiency so workingset includes swap as well as RSS.

      On such system, if there are lots of shared anonymous pages, it's really
      hard to figure out exactly how many each process consumes memory(ie, rss
      + wap) if the system has lots of shared anonymous memory(e.g, android).

      This patch introduces SwapPss field on /proc/<pid>/smaps so we can get
      more exact workingset size per process.

      Bongkyu tested it. Result is below.

      1. 50M used swap
      SwapTotal: 461976 kB
      SwapFree: 411192 kB

      $ adb shell cat /proc/*/smaps | grep "SwapPss:" | awk '{sum += $2} END

      pagemap: add mmap-exclusive bit for marking pages mapped only here

      This patch sets bit 56 in pagemap if this page is mapped only once.  It
      allows to detect exclusively used pages without exposing PFN:

      present file exclusive state
      0       0    0         non-present
      1       1    0         file page mapped somewhere else
      1       1    1         file page mapped only here
      1       0    0         anon non-CoWed page (shared with parent/child)
      1       0    1         anon CoWed page (or never forked)

      CoWed pages in (MAP_FILE | MAP_PRIVATE) areas are anon in this context.

      MMap-exclusive bit doesn't reflect potential page-sharing via swapcache:
      page could be mapped once but has several swap-ptes which point to it.
      Application could detect that by swap bit in pagemap entry and touch that
      pte via /proc/pid/mem to get real information.

      pagemap: check permissions and capabilities at open time

      This patchset makes pagemap useable again in the safe way (after row
      hammer bug it was made CAP_SYS_ADMIN-only).  This patchset restores access
      for non-privileged users but hides PFNs from them.

      Also it adds bit 'map-exclusive' which is set if page is mapped only here:
      it helps in estimation of working set without exposing pfns and allows to
      distinguish CoWed and non-CoWed private anonymous pages.

      Second patch removes page-shift bits and completes migration to the new
      pagemap format: flags soft-dirty and mmap-exclusive are available only in
      the new format.

      This patch (of 5):

      This patch moves permission checks from pagemap_read() into 
pagemap_open().

      Pointer to mm is saved in file->private_data. This reference pins only
      mm_struct itself. /proc/*/mem, maps, smaps already work in the same way.

      If the first access to a huge page was a store, there would be no existing
      zero pmd in this process's page tables.  There could be a zero pmd in
      another process's page tables, if it had done a load.  We can detect this
      case by noticing that the buffer_head returned from the filesystem is New,
      and ensure that other processes mapping this huge page have their page
      tables flushed.

      thp: fix zap_huge_pmd() for DAX

      The original DAX code assumed that pgtable_t was a pointer, which isn't
      true on all architectures.  Restructure the code to not rely on that
      assumption.

      dax: fix race between simultaneous faults

      If two threads write-fault on the same hole at the same time, the winner
      of the race will return to userspace and complete their store, only to
      have the loser overwrite their store with zeroes.  Fix this for now by
      taking the i_mmap_sem for write instead of read, and do so outside the
      call to get_block().  Now the loser of the race will see the block has
      already been zeroed, and will not zero it again.

      This severely limits our scalability.  I have ideas for improving it, but
      those can wait for a later patch.

      ext4: start transaction before calling into DAX

      Jan Kara pointed out that in the case where we are writing to a hole, we
      can end up with a lock inversion between the page lock and the journal
      lock.  We can avoid this by starting the transaction in ext4 before
      calling into DAX.  The journal lock nests inside the superblock
      pagefault lock, so we have to duplicate that code from dax_fault, like
      XFS does.

      ext4: add ext4_get_block_dax()

      DAX wants different semantics from any currently-existing ext4 get_block
      callback.  Unlike ext4_get_block_write(), it needs to honour the
      'create' flag, and unlike ext4_get_block(), it needs to be able to
      return unwritten extents.  So introduce a new ext4_get_block_dax() which
      has those semantics.

      We could also change ext4_get_block_write() to honour the 'create' flag,
      but that might have consequences on other users that I do not currently
      understand.

      ext4: use ext4_get_block_write() for DAX

      DAX relies on the get_block function either zeroing newly allocated
      blocks before they're findable by subsequent calls to get_block, or
      marking newly allocated blocks as unwritten.  ext4_get_block() cannot
      create unwritten extents, but ext4_get_block_write() can.

      In order to handle the !CONFIG_TRANSPARENT_HUGEPAGES case, we need to
      return VM_FAULT_FALLBACK from the inlined dax_pmd_fault(), which is

      functions to a new header, <linux/dax.h>.  We could also have moved
      VM_FAULT_* definitions to a new header, or a different header that isn't
      quite such a boil-the-ocean header as <linux/mm.h>, but this felt like
      the best option.

      thp: vma_adjust_trans_huge(): adjust file-backed VMA too

      This series of patches adds support for using PMD page table entries to
      map DAX files.  We expect NV-DIMMs to start showing up that are many
      gigabytes in size and the memory consumption of 4kB PTEs will be
      astronomical.

      The patch series leverages much of the Transparant Huge Pages
      infrastructure, going so far as to borrow one of Kirill's patches from
      his THP page cache series.

      This patch (of 10):

      Since we're going to have huge pages in page cache, we need to call adjust
      file-backed VMA, which potentially can contain huge pages.

      For now we call it for all VMAs.

      Probably later we will need to introduce a flag to indicate that the VMA
      has huge pages.

      fails without this patch. Before the previous commit it gets the wrong
      page, now it segfaults (which is imho better).

      This is because copy_vma() wrongly assumes that if vma->vm_file == NULL
      is irrelevant until the first fault which will use do_anonymous_page().
      This is obviously wrong for the special mapping.

                assert(mprotect(vdso, PAGE_SIZE, PROT_READ) == 0);

                // force another fault on the next check
                assert(madvise(vdso, 2 * PAGE_SIZE, MADV_DONTNEED) == 0);

                // now they no longer differ, the 2nd vm_pgoff is wrong
                printf("vdso pages differ: %d\n",
                        !!memcmp(vdso, vdso + PAGE_SIZE, PAGE_SIZE));

                return 0;
        }

      Output:

        vdso pages differ: 1
        vdso pages differ: 0

      This is because split_vma() correctly updates ->vm_pgoff, but the logic
      in insert_vm_struct() and special_mapping_fault() is absolutely broken,
      so the fault at vdso + PAGE_SIZE return the 1st page. The same happens
      if you simply unmap the 1st page.

      special_mapping_fault() does:

        pgoff = vmf->pgoff - vma->vm_pgoff;

      and this is _only_ correct if vma->vm_start mmaps the first page from
      ->vm_private_data array.

      vdso or any other user of install_special_mapping() is not anonymous,
      it has the "backing storage" even if it is just the array of pages.
      So we actually need to make vm_pgoff work as an offset in this array.

      Note: this also allows to fix another problem: currently gdb can't access
      "[vvar]" memory because in this case special_mapping_fault() doesn't work.
      Now that we can use ->vm_pgoff we can implement ->access() and fix this.

      mm: introduce vma_is_anonymous(vma) helper

      special_mapping_fault() is absolutely broken.  It seems it was always
      wrong, but this didn't matter until vdso/vvar started to use more than
      one page.

      And after this change vma_is_anonymous() becomes really trivial, it
      simply checks vm_ops == NULL.  However, I do think the helper makes
      sense.  There are a lot of ->vm_ops != NULL checks, the helper makes the
      caller's code more understandable (self-documented) and this is more
      grep-friendly.

      This patch (of 3):

      Preparation.  Add the new simple helper, vma_is_anonymous(vma), and change
      handle_pte_fault() to use it.  It will have more users.

      The name is not accurate, say a hpet_mmap()'ed vma is not anonymous.
      Perhaps it should be named vma_has_fault() instead.  But it matches the
      logic in mmap.c/memory.c (see next changes).  "True" just means that a
      page fault will use do_anonymous_page().

      Merge tag 'libnvdimm-for-4.3' of 
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

      Pull libnvdimm updates from Dan Williams:
       "This update has successfully completed a 0day-kbuild run and has
        appeared in a linux-next release.  The changes outside of the typical
        drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the
        removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and
        the introduction of ZONE_DEVICE + devm_memremap_pages().

        Summary:

         - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
           mechanism for adding device-driver-discovered memory regions to the
           kernel's direct map.

           This facility is used by the pmem driver to enable pfn_to_page()
           operations on the page frames returned by DAX ('direct_access' in
           'struct block_device_operations').

           For now, the 'memmap' allocation for these "device" pages comes
           from "System RAM".  Support for allocating the memmap from device
           memory will arrive in a later kernel.

         - Introduce memremap() to replace usages of ioremap_cache() and
           ioremap_wt().  memremap() drops the __iomem annotation for these
           mappings to memory that do not have i/o side effects.  The
           replacement of ioremap_cache() with memremap() is limited to the
           pmem driver to ease merging the api change in v4.3.

           Completion of the conversion is targeted for v4.4.

         - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
           driver, update the VFS DAX implementation and PMEM api to provide
           persistence guarantees for kernel operations on a DAX mapping.

         - Convert the ACPI NFIT 'BLK' driver to map the block apertures as
           cacheable to improve performance.

         - Miscellaneous updates and fixes to libnvdimm including support for
           issuing "address range scrub" commands, clarifying the optimal
           'sector size' of pmem devices, a clarification of the usage of the
           ACPI '_STA' (status) property for DIMM devices, and other minor
           fixes"

      device property: Don't overwrite addr when failing in 
device_get_mac_address

      The function device_get_mac_address is trying different property names
      in order to get the mac address. To check the return value, the variable
      addr (which contain the buffer pass by the caller) will be re-used. This
      means that if the previous property is not found, the next property will
      be read using a NULL buffer.

      Therefore it's only possible to retrieve the mac if node contains a
      property "mac-address". Fix it by using a temporary buffer for the
      return value.

      This has been introduced by commit 
4c96b7dc0d393f12c17e0d81db15aa4a820a6ab3

      usbnet: Fix a race between usbnet_stop() and the BH

      The race may happen when a device (e.g. YOTA 4G LTE Modem) is
      unplugged while the system is downloading a large file from the Net.

      Hardware breakpoints and Kprobes with delays were used to confirm that
      the race does actually happen.

      The race is on skb_queue ('next' pointer) between usbnet_stop()
      and rx_complete(), which, in turn, calls usbnet_bh().

      Here is a part of the call stack with the code where the changes to the
      queue happen. The line numbers are for the kernel 4.1.0:

      *0 __skb_unlink (skbuff.h:1517)
          prev->next = next;
      *1 defer_bh (usbnet.c:430)
          spin_lock_irqsave(&list->lock, flags);
          old_state = entry->state;
          entry->state = state;
          __skb_unlink(skb, list);
          spin_unlock(&list->lock);
          spin_lock(&dev->done.lock);
          __skb_queue_tail(&dev->done, skb);
          if (dev->done.qlen == 1)
              tasklet_schedule(&dev->bh);
          spin_unlock_irqrestore(&dev->done.lock, flags);
      *2 rx_complete (usbnet.c:640)
          state = defer_bh(dev, skb, &dev->rxq, state);

      At the same time, the following code repeatedly checks if the queue is
      empty and reads these values concurrently with the above changes:

      *0  usbnet_terminate_urbs (usbnet.c:765)
          /* maybe wait for deletions to finish. */
          while (!skb_queue_empty(&dev->rxq)
              && !skb_queue_empty(&dev->txq)
              && !skb_queue_empty(&dev->done)) {
                  schedule_timeout(msecs_to_jiffies(UNLINK_TIMEOUT_MS));
                  set_current_state(TASK_UNINTERRUPTIBLE);
                  netif_dbg(dev, ifdown, dev->net,
                        "waited for %d urb completions\n", temp);
          }
      *1  usbnet_stop (usbnet.c:806)
          if (!(info->flags & FLAG_AVOID_UNLINK_URBS))
              usbnet_terminate_urbs(dev);

      As a result, it is possible, for example, that the skb is removed from
      dev->rxq by __skb_unlink() before the check
      "!skb_queue_empty(&dev->rxq)" in usbnet_terminate_urbs() is made. It is
      also possible in this case that the skb is added to dev->done queue
      after "!skb_queue_empty(&dev->done)" is checked. So
      usbnet_terminate_urbs() may stop waiting and return while dev->done
      queue still has an item.

      Locking in defer_bh() and usbnet_terminate_urbs() was revisited to avoid
      this race.

      ceph: fix queuing inode to mdsdir's snaprealm

      During MDS failovers, MClientSnap message may cause kclient to move
      some inodes from root directory's snaprealm to mdsdir's snaprealm
      and queue snapshots for these inodes. For a FS has never created any
      snapshot, both root directory's snaprealm and mdsdir's snaprealm
      share the same snapshot contexts (both are ceph_empty_snapc). This
      confuses ceph_put_wrbuffer_cap_refs(), make it unable to distinguish
      snapshot buffers from head buffers.

      The fix is do not use ceph_empty_snapc as snaprealm's cached context.

      Furthermore, use directly virt_to_gfn for both PV and HVM domain rather
      than doing a special case for each of the them.

      xen: Use correctly the Xen memory terminologies

      Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN
      is meant, I suspect this is because the first support for Xen was for
      PV. This resulted in some misimplementation of helpers on ARM and
      confused developers about the expected behavior.

      For instance, with pfn_to_mfn, we expect to get an MFN based on the name.
      Although, if we look at the implementation on x86, it's returning a GFN.

      For clarity and avoid new confusion, replace any reference to mfn with
      gfn in any helpers used by PV drivers. The x86 code will still keep some
      reference of pfn_to_mfn which may be used by all kind of guests
      No changes as been made in the hypercall field, even
      though they may be invalid, in order to keep the same as the defintion
      in xen repo.

      Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a
      name to close to the KVM function gfn_to_page.

      Take also the opportunity to simplify simple construction such
      as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean 
up
      will come in follow-up patches.

      arm/xen: implement correctly pfn_to_mfn

      After the commit introducing convertion between DMA and guest addresses,
      all the callers of pfn_to_mfn are expecting to get a GFN (Guest Frame
      Number). On ARM, all the guests are auto-translated so the GFN is equal
      to the Linux PFN (Pseudo-physical Frame Number).

      The current implementation may return an MFN if the caller is passing a
      PFN associated to a mapped foreign grant. In pratice, I haven't seen
      the problem on running guest but we should fix it for the sake of
      correctness.

      Correct the implementation by always returning the pfn passed in 
parameter.

      A follow-up patch will take care to rename pfn_to_mfn to a suitable
      name.

      xen: Make clear that swiotlb and biomerge are dealing with DMA address

      The swiotlb is required when programming a DMA address on ARM when a
      device is not protected by an IOMMU.

      In this case, the DMA address should always be equal to the machine 
address.
      For DOM0 memory, Xen ensure it by have an identity mapping between the
      guest address and host address. However, when mapping a foreign grant
      reference, the 1:1 model doesn't work.

      For ARM guest, most of the callers of pfn_to_mfn expects to get a GFN
      (Guest Frame Number), i.e a PFN (Page Frame Number) from the Linux point
      of view given that all ARM guest are auto-translated.

      Even though the name pfn_to_mfn is misleading, we need to ensure that
      those caller get a GFN and not by mistake a MFN. In pratical, I haven't
      seen error related to this but we should fix it for the sake of
      correctness.

      In order to fix the implementation of pfn_to_mfn on ARM in a follow-up
      patch, we have to introduce new helpers to return the DMA from a PFN and
      the invert.

      On x86, the new helpers will be an alias of pfn_to_mfn and mfn_to_pfn.

      The helpers will be used in swiotlb and xen_biovec_phys_mergeable.

      This is necessary in the latter because we have to ensure that the
      biovec code will not try to merge a biovec using foreign page and
      another using Linux memory.

      Lastly, the helper mfn_to_local_pfn has been renamed to bfn_to_local_pfn
      given that the only usage was in swiotlb.

      xen: limit memory to architectural maximum

      When a pv-domain (including dom0) is started it tries to size it's
      p2m list according to the maximum possible memory amount it ever can
      achieve. Limit the initial maximum memory size to the architectural
      limit of the hardware in order to avoid overflows during remapping
      of memory.

      This problem will occur when dom0 is started with an initial memory
      size being a multiple of 1GB, but without specifying it's maximum
      memory size. The kernel must be configured without
      CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen.

      xen: avoid another early crash of memory limited dom0

      Commit b1c9f169047b ("xen: split counting of extra memory pages...")
      introduced an error when dom0 was started with limited memory occurring
      only on some hardware.

      The problem arises in case dom0 is started with initial memory and
      maximum memory being the same. The kernel must be configured without
      CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen. If all
      of this is true and the E820 map of the machine is sparse (some areas
      are not covered) then the machine might crash early in the boot
      process.

      In this case the area a0000-dffff isn't present in the map. This will
      confuse the memory setup of the domain when remapping the memory from
      such holes to populated areas.

      To avoid the problem the accounting of to be remapped memory has to
      count such holes in the E820 map as well.

      parisc: Filter out spurious interrupts in PA-RISC irq handler

      When detecting a serial port on newer PA-RISC machines (with iosapic) we 
have a
      long way to go to find the right IRQ line, registering it, then 
registering the
      serial port and the irq handler for the serial port. During this phase 
spurious
      interrupts for the serial port may happen which then crashes the kernel 
because
      the action handler might not have been set up yet.

      So, basically it's a race condition between the serial port hardware and 
the
      CPU which sets up the necessary fields in the irq sructs. The main reason 
for
      this race is, that we unmask the serial port irqs too early without 
having set
      up everything properly before (which isn't easily possible because we 
need the
      IRQ number to register the serial ports).

      This patch is a work-around for this problem. It adds checks to the CPU 
irq
      handler to verify if the IRQ action field has been initialized already. 
If not,
      we just skip this interrupt (which isn't critical for a serial port at 
bootup).
      The real fix would probably involve rewriting all PA-RISC specific IRQ 
code
      (for CPU, IOSAPIC, GSC and EISA) to use IRQ domains with proper parenting 
of
      the irq chips and proper irq enabling along this line.

      This bug has been in the PA-RISC port since the beginning, but the crashes
      happened very rarely with currently used hardware.  But on the latest 
machine
      which I bought (a C8000 workstation), which uses the fastest CPUs (4 x 
PA8900,
      1GHz) and which has the largest possible L1 cache size (64MB each), the 
kernel
      crashed at every boot because of this race. So, without this patch the 
machine
      would currently be unuseable.

      For the record, here is the flow logic:
      1. serial_init_chip() in 8250_gsc.c calls iosapic_serial_irq().
      2. iosapic_serial_irq() calls txn_alloc_irq() to find the irq.
      3. iosapic_serial_irq() calls cpu_claim_irq() to register the CPU irq
      4. cpu_claim_irq() unmasks the CPU irq (which it shouldn't!)
      5. serial_init_chip() then registers the 8250 port.
      Problems:
      - In step 4 the CPU irq shouldn't have been registered yet, but after 
step 5
      - If serial irq happens between 4 and 5 have finished, the kernel will 
crash

      PCI,parisc: Enable 64-bit bus addresses on PA-RISC

      Commit 3a9ad0b ("PCI: Add pci_bus_addr_t") unconditionally introduced 
usage of
      64-bit PCI bus addresses on all 64-bit platforms which broke PA-RISC.

      It turned out that due to enabling the 64-bit addresses, the PCI logic 
decided
      to use the GMMIO instead of the LMMIO region. This commit simply disables
      registering the GMMIO and thus we fall back to use the LMMIO region as 
before.

      Reverts commit 45ea2a5fed6dacb9bb0558d8b21eacc1c45d5bb4

      virtio_balloon: do not change memory amount visible via /proc/meminfo

      Balloon device is frequently used as a mean of cooperative memory control
      in between guest and host to manage memory overcommitment. This is the
      typical case for any hosting workload when KVM guest is provided for
      end-user.

      Though there is a problem in this setup. The end-user and hosting provider
      have signed SLA agreement in which some amount of memory is guaranted for
      the guest. The good thing is that this memory will be given to the guest
      when the guest will really need it (f.e. with OOM in guest and with
      VIRTIO_BALLOON_F_DEFLATE_ON_OOM configuration flag set). The bad thing
      is that end-user does not know this.

      Balloon by default reduce the amount of memory exposed to the end-user
      each time when the page is stolen from guest or returned back by using
      adjust_managed_page_count and thus /proc/meminfo shows reduced amount
      of memory.

      Fortunately the solution is simple, we should just avoid to call
      adjust_managed_page_count with VIRTIO_BALLOON_F_DEFLATE_ON_OOM set.

      Btrfs: don't initialize a space info as full to prevent ENOSPC

      Commit 2e6e518335f8 ("Btrfs: fix block group ->space_info null pointer
      dereference") accidently marked a space info as full when initializing
      it with a value of 0 total bytes. This introduces an ENOSPC problem when
      writing file data if we mount a filesystem that has no data block groups
      allocated, because the data space info is initialized with 0 total bytes,
      marked as full, and it never gets its total bytes incremented by a
      (positive) value to unmark it as full (because there are no data block
      groups loaded when the fs is mounted).
      For metadata and system spaces this issue can never happen since we always
      have at least one metadata block group and one system block group (even
      for an empty filesystem).

      So fix this by just not initializing a space info as full, reverting the
      offending part of the commit mentioned above.

      The following test case for fstests reproduces the issue:

      NTB: Remove dma_sync_wait from ntb_async_rx

      The dma_sync_wait can hurt the performance of workloads mixed with both
      large and small frames.  Large frames will be copied using the dma
      engine.  Small frames will be copied by the cpu.  The dma_sync_wait
      prevents the cpu and dma engine copying in parallel.

      In the period where the cpu is copying, the dma engine is stopped.  The
      dma engine is not doing any useful work to copy large frames during that
      time, and the additional time to restart the dma engine for the next
      large frame.  This will decrease the throughput for the portion of a
      workload with large frames.

      In the period where the dma engine is copying, the cpu is held up
      waiting for dma to complete.  The small frames processing will be
      delayed until the dma is complete.  The RX frames are completed
      in-order, and the processing of small frames takes very little time, so
      dma_sync_wait may have an insignificant impact on the respose time of
      frames.  The more significant impact is to the system, because the delay
      in dma_sync_wait is implemented as busy non-blocking wait.  This can
      prevent the delayed core from doing any useful work, even if it could be
      processing work for other drivers, unrelated to transport RX processing.

      After applying the earlier patch to fix out-of-order RX acknoledgement,
      the dma_sync_wait is no longer necessary.  Remove it, so that cpu memcpy
      will proceed immediately for small frames, in parallel with ongoing dma
      for large frames.  Do not hold up the cpu from doing work while dma is
      in progress.  The prior fix will continue to ensure in-order completion
      of the RX frames to the upper layer, and in-order delivery of the RX
      acknoledgement.

      NTB: Add flow control to the ntb_netdev

      Right now if we push the NTB really hard, we start dropping packets due
      to not able to process the packets fast enough. We need to st:qop the
      upper layer from flooding us when that happens.

      A timer is necessary in order to restart the queue once the resource has
      been processed on the receive side. Due to the way NTB is setup, the
      resources on the tx side are tied to the processing of the rx side and
      there's no async way to know when the rx side has released those
      resources.

      NFSv4: Respect the server imposed limit on how many changes we may cache

      The NFSv4 delegation spec allows the server to tell a client to limit how
      much data it cache after the file is closed. In return, the server
      guarantees enough free space to avoid ENOSPC situations, etc.
      Prior to this patch, we assumed we could always cache aggressively after
      close. Unfortunately, this causes problems with servers that set the
      limit to 0 and therefore do not offer any ENOSPC guarantees.

      ARM: 8429/1: disable GCC SRA optimization

      While working on the 32-bit ARM port of UEFI, I noticed a strange
      corruption in the kernel log. The following snprintf() statement
      (in drivers/firmware/efi/efi.c:efi_md_typeattr_format())

        snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",

      was producing the following output in the log:

        |    |   |   |   |    |WB|WT|WC|UC]
        |    |   |   |   |    |WB|WT|WC|UC]

        |RUN|   |   |   |    |   |   |   |UC]

      As it turns out, this is caused by incorrect code being emitted for
      the string() function in lib/vsprintf.c. The following code

        if (!(spec.flags & LEFT)) {
                while (len < spec.field_width--) {
                        if (buf < end)
                                *buf = ' ';
                        ++buf;
                }
        }
        for (i = 0; i < len; ++i) {
                if (buf < end)
                        *buf = *s;
                ++buf; ++s;
        }
        while (len < spec.field_width--) {
                if (buf < end)
                        *buf = ' ';
                ++buf;
        }

      when called with len == 0, triggers an issue in the GCC SRA optimization
      pass (Scalar Replacement of Aggregates), which handles promotion of signed
      struct members incorrectly. This is a known but as yet unresolved issue.
      (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
      case, it is causing the second while loop to be executed erroneously a
      single time, causing the additional space characters to be printed.

      So disable the optimization by passing -fno-ipa-sra.

      cxl: abort cxl_pci_enable_device_hook() if PCI channel is offline

      cxl_pci_enable_device_hook() is called when attempting to enable an AFU
      sitting on a vPHB. At present, the state of the underlying CXL card's PCI
      channel is only checked when it calls cxl_afu_check_and_enable() at the
      very end, after it has already set DMA options and initialised a default
      context.

      Check the CXL card's link status before setting DMA options or 
initialising
      a default context. If the link is down, print a warning and return
      immediately.

      powerpc/powernv/pci-ioda: fix kdump with non-power-of-2 crashkernel=

      The 32-bit TCE table initialization relies on the DMA window having a
      size equal to a power of 2 (and checks for it explicitly). But
      crashkernel= has no constraint that requires a power-of-2 be specified.
      This causes the kdump kernel to fail to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      powerpc/powernv/pci-ioda: fix 32-bit TCE table init in kdump kernel

      When attempting to kdump with the 4.2 kernel, we see for each PCI
      device:

       pci 0003:01     : [PE# 000] Assign DMA32 space
       pci 0003:01     : [PE# 000] Setting up 32-bit TCE table at 0..80000000

      and eventually the kdump kernel fails to boot as none of the PCI devices
      (including the disk controller) are successfully initialized.

      The EINVAL response is because the DMA window (the 2GB base window) is
      larger than the kdump kernel's reserved memory (crashkernel=, in this
      case specified to be 1024M). The check in question,

       if ((window_size > memory_hotplug_max()) || !is_power_of_2(window_size))

      is a valid sanity check for pnv_pci_ioda2_table_alloc_pages(), so adjust
      the caller to pass in a smaller window size if our maximum memory value
      is smaller than the DMA window.

      After this change, the PCI devices successfully set up the 32-bit TCE
      table and kdump succeeds.

      The problem was seen on a Firestone machine originally.

      ALSA: usb-audio: Change internal PCM order

      New PCMs will now be added to the end of the chip's PCM list instead of 
to the
      front. This changes the way streams are combined so that the first capture
      stream will now be merged with the first playback stream instead of the 
last.

      This fixes a problem with ASUS U7. Cards with one playback stream and 
cards
      without capture streams should be unaffected by this change.

      Exception added for M-Audio Audiophile USB (tm) since it seems to have a

      scsi_error_handler                        scsi_host_dev_release

        set_current_state(TASK_INTERRUPTIBLE)
        schedule()

      The most straightforward solution seems to be to invert the ordering of
      the set_current_state and kthread_should_stop.

      The issue has been noticed during reboot test on a 3.0 based kernel but
      the current code seems to be affected in the same way.

      fcoe: Convert use of __constant_htons to htons

      In little endian cases, the macro htons unfolds to __swab16 which
      provides special case for constants. In big endian cases,
      __constant_htons and htons expand directly to the same expression.
      So, replace __constant_htons with htons with the goal of getting
      rid of the definition of __constant_htons completely.

      The semantic patch that performs this transformation is as follows:

      @@expression x;@@

      - __constant_htons(x)

         sysfs, PCI resource handling path

      2. gioc_lock spinlock to protect list operations over multiple
      controllers

      Subject: [PATCH] mpt2sas setpci reset oops fix

      In mpt2sas driver due to lack of synchronization between ioctl,
      BRM status access through sysfs, pci resource removal kernel oops
      happen as ioctl path and BRM status sysfs access path still tries
      to access the removed resources

      Two locks added to provide syncrhonization

      1. pci_access_mutex: Mutex to synchronize ioctl,sysfs show path and
      pci resource handling. PCI resource freeing will lead to free
      vital hardware/memory resource, which might be in use by cli/sysfs
      path functions resulting in Null pointer reference followed by kernel
      crash. To avoid the above race condition we use mutex syncrhonization
      which ensures the syncrhonization between cli/sysfs_show path

      Note: pci_access_mutex is used only if nytro warpdrive cards
      (ioc->is_warpdrive based on device id) are used
      as we could not test this case with other SAS2 HBA cards
      We can remove this check if this behaviour confirmed from other
      cards.

      2. spinlock on list operations over IOCs

      Case: when multiple warpdrive cards(IOCs) are in use
      Each IOC will added to the ioc list stucture on initialization.
      Watchdog threads run at regular intervals to check IOC for any
      fault conditions which will trigger the dead_ioc thread to
      deallocate pci resource, resulting deleting the IOC netry from list,
      this deletion need to protected by spinlock to enusre that
      ioc removal is syncrhonized, if not synchronized it might lead to
      list_del corruption as the ioc list is traversed in cli path

      lpfc: Fix possible use-after-free and double free in 
lpfc_mbx_cmpl_rdp_page_a2()

      If the bf_get() call in lpfc_mbx_cmpl_rdp_page_a2() does succeeds, 
execution
      continues normally and mp gets kfree()d.

      If the subsequent call to lpfc_sli_issue_mbox() fails execution jumps to 
the
      error label where lpfc_mbuf_free() is called with mp->virt and mp->phys as
      function arguments. This is the use after free. Following the use after 
free mp
      gets kfree()d again which is a double free.

      Additionally, we cannot iterate over the sas_device_list without

      added or deleted as we iterate. This patch refactors _scsih_probe_sas()

      KVM: dynamic halt-polling

      There is a downside of always-poll since poll is still happened for idle
      vCPUs which can waste cpu usage. This patchset add the ability to adjust
      halt_poll_ns dynamically, to grow halt_poll_ns when shot halt is detected,
      and to shrink halt_poll_ns when long halt is detected.

      There are two new kernel parameters for changing the halt_poll_ns:
      halt_poll_ns_grow and halt_poll_ns_shrink.

                              no-poll      always-poll    dynamic-poll
      -----------------------------------------------------------------------
      Idle (nohz) vCPU %c0     0.15%        0.3%            0.2%
      Idle (250HZ) vCPU %c0    1.1%         4.6%~14%        1.2%
      TCP_RR latency           34us         27us            26.7us

      "Idle (X) vCPU %c0" is the percent of time the physical cpu spent in
      c0 over 60 seconds (each vCPU is pinned to a pCPU). (nohz) means the
      guest was tickless. (250HZ) means the guest was ticking at 250HZ.

      The big win is with ticking operating systems. Running the linux guest
      with nohz=off (and HZ=250), we save 3.4%~12.8% CPUs/second and get close
      to no-polling overhead levels by using the dynamic-poll. The savings
      should be even higher for higher frequency ticks.

      X86EMU_CONTINUE blocks actual use of the value.  However, the value of

      both initialized unconditionally.

      Note that "leaf" now points to the first unused element of the array,

      net: fec: normalize return value of pm_runtime_get_sync() in MDIO write

      If fec MDIO write method succeeds its return value comes from
      call to pm_runtime_get_sync().
      But pm_runtime_get_sync() can also return 1.

      In case of Micrel KSZ9031 PHY this value will then
      be returned along the call chain of phy_write() ->
      ksz9031_extended_write() -> ksz9031_center_flp_timing() ->
      ksz9031_config_init() -> phy_init_hw() -> phy_attach_direct() ->
      phy_connect_direct().

      Then phy_connect() will cast it into a pointer using ERR_PTR(),
      which then fec_enet_mii_probe() will try to dereference
      resulting in an oops.

      Fix it by normalizing return value of pm_runtime_get_sync()
      to be zero if positive in MDIO write method.

      be2net: Revert "make the RX_FILTER command asynchronous" commit

      The be_cmd_rx_filter() routine sends a non-embedded cmd to the FW and used
      a pre-allocated dma memory to hold the cmd payload. This worked fine when
      this cmd was synchronous. This cmd was changed to asynchronous mode by the
      commit 8af65c2f4("make the RX_FILTER command asynchronous"). So now when
      there are two quick invocations of this cmd, the 2nd request may end up
      overwriting the first request, causing FW cmd corruption.

      This patch reverts the offending commit and hence fixes the regression.

registers
         at 32 bits level.

      2) Restore previous default behaviour in bridge netfilter when 
CONFIG_IPV6=n,

      3) Out of bound access in ipset hash:net* set types, reported by Dave 
Jones'
         KASan utility, patch from Jozsef Kadlecsik.

      4) Fix ipset compilation with gcc 4.4.7 related to C99 initialization of
         unnamed unions, patch from Elad Raz.

      5) Add a workaround to address inconsistent endianess in the res_id field 
of
         nfnetlink batch messages, reported by Florian Westphal.

      6) Fix error paths of CT/synproxy since the conntrack template was moved 
to use
         kmalloc, patch from Daniel Borkmann.

      All of them look good to me to reach 4.2, I can route this to -stable 
myself

      net/ipv6: Correct PIM6 mrt_lock handling

      In the IPv6 multicast routing code the mrt_lock was not being released
      correctly in the MFC iterator, as a result adding or deleting a MIF would
      cause a hang because the mrt_lock could not be acquired.

      This fix is a copy of the code for the IPv4 case and ensures that the lock
      is released correctly.

      spi: Fix documentation of spi_alloc_master()

      Actually, spi_master_put() after spi_alloc_master() must _not_ be followed
      by kfree(). The memory is already freed with the call to spi_master_put()
      through spi_master_class, which registers a release function. Calling both
      spi_master_put() and kfree() results in often nasty (and delayed) crashes
      elsewhere in the kernel, often in the networking stack.

      This reverts commit eb4af0f5349235df2e4a5057a72fc8962d00308a.

      or
      http://lkml.iu.edu/hypermail/linux/kernel/1209.0/00790.html

      Alexey Klimov: This revert becomes valid after
      94c69f765f1b4a658d96905ec59928e3e3e07e6a when spi-imx.c
      has been fixed and there is no need to call kfree() so comment
      for spi_alloc_master() should be fixed.

      task_work: remove fifo ordering guarantee

      In commit f341861fb0b ("task_work: add a scheduling point in
      task_work_run()") I fixed a latency problem adding a cond_resched()
      call.

      Later, commit ac3d0da8f329 added yet another loop to reverse a list,
      bringing back the latency spike :

      I've seen in some cases this loop taking 275 ms, if for example a
      process with 2,000,000 files is killed.

      We could add yet another cond_resched() in the reverse loop, or we
      can simply remove the reversal, as I do not think anything
      would depend on order of task_work_add() submitted works.

      Input: i8042 - lower log level for "no controller" message

      Nowadays the machines without i8042 controller is popular, and no need
      to print "No controller found" message in the error log level, which
      annoys at booting in quiet mode.  Let's lower it info level.

      rtc: s5m: fix to update ctrl register

      According to datasheet, the S2MPS13X and S2MPS14X should update write
      buffer via setting WUDR bit to high after ctrl register is written.

      If not, ALARM interrupt of rtc-s5m doesn't happen first time when i use
      tools/testing/selftests/timers/rtctest.c test program and hour format is
      used to 12 hour mode in Odroid-XU3 board.

      One more issue is the RTC doesn't keep time on Odroid-XU3 board when i
      turn on board after power off even if RTC battery is connected. It can
      be solved as setting WUDR & RUDR bits to high at the same time after
      RTC_CTRL register is written. It's same with condition of only writing
      ALARM registers, so this is for only S2MPS14 and we should set WUDR &
      A_UDR bits to high on S2MPS13.

      I can't find any reasonable description about this like fix from
      datasheet, but can find similar codes from rtc driver source of
      hardkernel kernel and vendor kernel.

      ARM: config: Switch PXA27x platforms to use PXA RTC driver

      With the SA1100 and PXA RTC drivers be mutually exclusive and no
      longer sharing hardware, PXA27x/PXA3xx platforms must use the PXA RTC
      driver as the SA1100 platform device is no longer registered.

      This change should be almost transparent to userspace. Former users of
      pxa-rtc should be aware that 2 RTCs will be available on their kernels,
      rtc0 being sa1100-rtc and rtc1 being pxa-rtc. Any userspace relying on
      the fact that rtc0 was pxa-rtc should be fixed.

      As a consequence:
       - the first reboot after the switch will have the wrong time,
       - on dual boot platform where the other OS programs some logic into the
         sa1100 rtc IP, a lack of fix in userspace, ie. a kernel changing
         sa1100-rtc thinking it is pxa-rtc could have dire consequence, such
         as wiping the other OS data partition.

      (Thanks to Robert Jarmik for help on the above commit text.)

      rtc: sa1100/pxa: convert to run-time register mapping

      SA1100 and PXA differ only in register offsets which are currently
      hardcoded in a machine specific header. Some arm64 platforms (PXA1928)
      have this RTC block as well (and not the PXA270 variant).

      Convert the driver to use ioremap and set the register offsets 
dynamically.
      Since we are touching all the register accesses, convert them all to
      readl_relaxed/writel_relaxed.

      ARM: pxa: add memory resource to SA1100 RTC device

      The drivers for the SA1100 and PXA RTCs are now mutually exclusive, so
      add the memory resource for the sa1100-rtc device. Since the memory
      resource is already present in the pxa_rtc_resources, that makes
      sa1100_rtc_resources and pxa_rtc_resources equivalent, so use
      pxa_rtc_resources for both devices and remove the duplicate
      sa1100_rtc_resources.

      rtc: pxa: convert to use shared sa1100 functions

      Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a
      superset of functionality. Having 2 drivers sharing the same memory
      resource is not allowed by the driver model if resources are properly
      declared. This problem was avoided by not adding memory resources to the
      SA1100 RTC driver, but that prevents clean-up of the SA1100 driver.

      This commit converts the PXA RTC to use the exported SA1100 RTC
      functions. Now the sa1100-rtc and pxa-rtc devices are mutually
      exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

      ALSA: hda - Enable headphone jack detect on old Fujitsu laptops

      According to the bug report, FSC Amilo laptops with ALC880 can detect
      the headphone jack but currently the driver disables it.  It's partly
      intentionally, as non-working jack detect was reported in the past.
      Let's enable now.

      rtc: s3c: fix disabled clocks for alarm

      The clock enable/disable codes for alarm have been removed from
      commit 24e1455493da ("drivers/rtc/rtc-s3c.c: delete duplicate clock
      control") and the clocks are disabled even if alarm is set, so alarm
      interrupt can't happen.

      The s3c_rtc_setaie function can be called several times with 'enabled'
      argument having same value, so it needs to check whether clocks are
      enabled or not.

      According to the Armada38x functional errata FE-3124064, writing to

      TIME register, issue a dummy write of 0x0 twice to the RTC Status
      register.  This is the updated implementation of the Errata that
      eliminates the need of the long 100ms delay during the RTC set time

      The change removes redundant sysfs binary file boundary checks, since
      this task is already done on caller side in fs/sysfs/file.c

      The change enables burst mode of access to SRAM for any read()/write()
      operations, it is worth to mention that this may influence on
      userspace, for instance prior to the change

        read(fd, buf, 1);
        read(fd, buf + 1, 1);

      and

        read(fd, buf, 2);

      sequences of syscalls over DS1511's sysfs "nvram" fd led to different
      DS1511 state changes and/or buf content, if some userspace applications
      are written specifically for DS1511 and exploit this strange
      "feature", they may be impacted.

      Also the change corrects NVRAM size accessible to userspace from 255
      bytes to 256 bytes.

      If century field is supported by the RTC CMOS device, then we should use
      it and then do not consider years greater that 169 as an error.

      For information, the year field of the rtc_time structure contains the
      value to add to 1970 to obtain the current year.

      This was a hack to be able to support years for 1970 to 2069.
      This patch remains compatible with this implementation.

      rtc: Drop (un)likely before IS_ERR(_OR_NULL)

      IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
      is no need to do that again from its callers. Drop it.

      gemini driver was using likely() for a failure case while the rtc driver
      is getting registered. That looks wrong and it should really be
      unlikely. But because we are killing all the unlikely() flags, lets kill
      that too.

      rtc: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

  Author: Adrian Huang <adrianhuang0701@xxxxxxxxx>
  Date:   Mon Jul 6 12:19:12 2015 +0800

      rtc: cmos: Cancel alarm timer if alarm time is equal to now+1 seconds

      Steps to reproduce the problem:
        1) Enable RTC wake-up option in BIOS Setup
        2) Issue one of these commands in the OS: "poweroff"
           or "shutdown -h now"
        3) System will shut down and then reboot automatically

      Root-cause of the issue:
        1) During the shutdown process, the hwclock utility is used
           to save the system clock to hardware clock (RTC).
        2) The hwclock utility invokes ioctl() with RTC_UIE_ON. The
           kernel configures the RTC alarm for the periodic interrupt
           (every 1 second).
        3) The hwclock uitlity closes the /dev/rtc0 device, and the
           kernel disables the RTC alarm irq (AIE bit of Register B)
           via ioctl() with RTC_UIE_OFF. But, the configured alarm
           time is the current_time + 1.
        4) After the next 1 second is elapsed, the AF (alarm
           interrupt flag) of Register C is set.
        5) The S5 handler in BIOS is invoked to configure alarm
           registers (enable AIE bit and configure alarm date/time).
           But, BIOS does not clear the previous interrupt status
           during alarm configuration. Therefore, "AF=AIE=1" causes
           the rtc device to trigger an interrupt.
        6) So, the machine reboots automatically right after shutdown.

      This patch cancels the alarm timer if the following condictions are
      met (suggested by Alexandre):
        1) The configured alarm time is equal to current_time + 1
           seconds.
        2) The AIE timer is not in use.

      The member 'alarm_expires' is introduced in struct cmos_rtc because
      of the following reasons:
        1) The configured alarm time can be retrieved from
           cmos_read_alarm(), but we need to take the 'wrapped
           timestamp' and 'time rollover' into consideration. The
           function __rtc_read_alarm() eliminates the concerns. To
           avoid the duplicated code in the lower level RTC driver,
           invoking __rtc_read_alarm from the lower level RTC driver
           is not encouraged. Moreover, the compilation error 'the
           undefined __rtc_read_alarm" is observed if the lower level
           RTC driver is compiled as a kernel module.
        2) The uie_rtctimer.node.expires and aie_timer.node.expires can
           be retrieved for the configured alarm time. But, the problem
           is that either of them might configure the CMOS alarm time.
           We cannot make sure UIE timer or AIE tiemr configured the
           CMOS alarm time before. (uie_rtctimer or aie_timer is enabled
           and then is disabled).
        3) The patch introduces the member 'alarm_expires' to keep the
           newly configured alarm time, so the above-mentioned concerns
           can be eliminated.

      The issue goes away after 20-time shutdown tests.

      rtc: da9063: Add DA9062 RTC capability to DA9063 RTC driver

      Add DA9062 RTC support into the existing DA9063 RTC driver component by
      using generic access tables for common register and bit mask definitions.

      The following change will add generic register and bit mask support to the
      DA9063 RTC. The changes are slightly complicated by requiring support for
      three register sets: DA9063-AD, DA9063-BB and DA9062-AA.

      The following alterations have been made to the DA9063 RTC:

      - Addition of a da9063_compatible_rtc_regmap structure to hold all generic
        registers and bitmasks for this type of RTC component.
      - A re-write of struct da9063 to use pointers for regmap and compatible
        registers/masks definitions
      - Addition of a of_device_id table for DA9063 and DA9062 defaults
      - Refactoring functions to use struct da9063_compatible_rtc accesses to
        generic registers/masks instead of using defines from registers.h
      - Re-work of da9063_rtc_probe() to use of_match_node() and 
dev_get_regmap()
        to provide initialisation of generic registers and masks and access to
        regmap

      rtc: opal: Enable alarms only when opal supports tpo

      rtc-opal driver provides support for rtc alarms via
      timed-power-on(tpo). However some Power platforms like BML use a fake
      rtc clock and don't support tpo. Such platforms are indicated by the
      missing 'has-tpo' property in the device tree.

      Current implementation however enables callback for
      rtc_class_ops.read/set alarm irrespective of the tpo support from the
      platform. This results in a failed opal call when kernel tries to read
      an existing alarms via opal_get_tpo_time during rtc device registration.

      This patch fixes this issue by setting opal_rtc_ops.read/set_alarm
      callback pointers only when tpo is supported.

      rtc: pcf2127: use OFS flag to detect unreliable date and warn the user

      The PCF2127 datasheet states that it's wrong to say that the date in
      unreliable if BLF (battery low flag) is set but instead, OSF (seconds
      register) should be used to check if oscillator, for any reason, stopped.
      Battery may be low (usually below 2V5 threshold) but the date may be 
anyway
      correct (typically date is unreliable when input voltage is below 1V2).

      rtc: use rtc_valid_tm() error code when reading date/time

      There's a wrong comment in some RTC drivers that say it's better to ignore
      rtc_valid_tm() when reading RTC timestamp. However this is wrong and is
      better to return to the userspace the error if timestamp is not valid.

      rtc: ds1307: Support optional wakeup interrupt source

      With the recent pinctrl-single changes, SoCs such as Texas
      Instrument's OMAP processors can treat wake-up events from deeper idle
      states as interrupts.

      Let's add support for the optional second interrupt for wake-up using
      the generic wakeirq support added in commit 4990d4fe327b ("PM /
      Wakeirq: Add automated device wake IRQ handling")

      Finally, to pass the wake-up interrupt in the dts file,
      interrupts-extended property needs to be passed.

      This is similar in approach to commit 2a0b965cfb6e ("serial: omap: Add
      support for optional wake-up") + ee83bd3b6483 ("serial: omap: Switch
      wake-up interrupt to generic wakeirq")

      x86/vm86: Block non-root vm86(old) if mmap_min_addr != 0

      vm86 exposes an interesting attack surface against the entry

      just turn it off in that case.

      There are some reports that vbetool can work despite setting
      mmap_min_addr to zero.  This shouldn't break that use case,
      as CAP_SYS_RAWIO already overrides mmap_min_addr.

      mm: make GUP handle pfn mapping unless FOLL_GET is requested

      With DAX, pfn mapping becoming more common.  The patch adjusts GUP code to
      cover pfn mapping for cases when we don't need struct page to proceed.

      To make it possible, let's change follow_page() code to return -EEXIST
      error code if proper page table entry exists, but no corresponding struct
      page.  __get_user_page() would ignore the error code and move to the next
      page frame.

      The immediate effect of the change is working MAP_POPULATE and mlock() on
      DAX mappings.

      mm: fix status code which move_pages() returns for zero page

      The manpage for move_pages(2) specifies that status code for zero page is
      supposed to be -EFAULT.  Currently kernel return -ENOENT in this case.

      follow_page() can do it for us, if we would ask for FOLL_DUMP.  The use of
      FOLL_DUMP also means that the upper layer page tables pages are no longer
      allocated.

      mm: memcontrol: bring back the VM_BUG_ON() in mem_cgroup_swapout()

      Clark stumbled over a VM_BUG_ON() in -RT which was then was removed by
      Johannes in commit f371763a79d ("mm: memcontrol: fix false-positive
      VM_BUG_ON() on -rt").  The comment before that patch was a tiny bit better
      than it is now.  While the patch claimed to fix a false-postive on -RT
      this was not the case.  None of the -RT folks ACKed it and it was not a
      false positive report.  That was a *real* problem.

      This patch updates the comment that is improper because it refers to
      "disabled preemption" as a consequence of that lock being taken.  A
      spin_lock() disables preemption, true, but in this case the code relies on
      the fact that the lock _also_ disables interrupts once it is acquired.
      And this is the important detail (which was checked the VM_BUG_ON()) which
      needs to be pointed out.  This is the hint one needs while looking at the
      code.  It was explained by Johannes on the list that the per-CPU variables
      are protected by local_irq_save().  The BUG_ON() was helpful.  This code
      has been workarounded in -RT in the meantime.  I wouldn't mind running
      into more of those if the code in question uses *special* kind of locking
      since now there is no verification (in terms of lockdep or BUG_ON()) and
      therefore I bring the VM_BUG_ON() check back in.

      The two functions after the comment could also have a "local_irq_save()"
      dance around them in order to serialize access to the per-CPU variables.
      This has been avoided because the interrupts should be off.

      genalloc: add support of multiple gen_pools per device

      This change fills devm_gen_pool_create()/gen_pool_get() "name" argument
      stub with contents and extends of_gen_pool_get() functionality on this
      basis.

      If there is no associated platform device with a device node passed to
      of_gen_pool_get(), the function attempts to get a label property or device
      node name (= repeats MTD OF partition standard) and seeks for a named
      gen_pool registered by device of the parent device node.

      The main idea of the change is to allow registration of independent
      gen_pools under the same umbrella device, say "partitions" on "storage
      device", the original functionality of one "partition" per "storage
      device" is untouched.

      genalloc: add name arg to gen_pool_get() and devm_gen_pool_create()

      This change modifies gen_pool_get() and devm_gen_pool_create() client
      interfaces adding one more argument "name" of a gen_pool object.

      Due to implementation gen_pool_get() is capable to retrieve only one
      gen_pool associated with a device even if multiple gen_pools are created,
      fortunately right at the moment it is sufficient for the clients, hence
      provide NULL as a valid argument on both producer devm_gen_pool_create()
      and consumer gen_pool_get() sides.

      Because only one created gen_pool per device is addressable, explicitly
      add a restriction to devm_gen_pool_create() to create only one gen_pool
      per device, this implies two possible error codes returned by the
      function, account it on client side (only misc/sram).  This completes
      client side changes related to genalloc updates.

      mm: defer flush of writable TLB entries

      If a PTE is unmapped and it's dirty then it was writable recently.  Due to
      deferred TLB flushing, it's best to assume a writable TLB cache entry
      exists.  With that assumption, the TLB must be flushed before any IO can
      start or the page is freed to avoid lost writes or data corruption.  This
      patch defers flushing of potentially writable TLBs as long as possible.

      mm: send one IPI per CPU to TLB flush all entries after unmapping pages

      An IPI is sent to flush remote TLBs when a page is unmapped that was
      potentially accesssed by other CPUs.  There are many circumstances where
      this happens but the obvious one is kswapd reclaiming pages belonging to a
      running process as kswapd and the task are likely running on separate
      CPUs.

      On small machines, this is not a significant problem but as machine gets
      larger with more cores and more memory, the cost of these IPIs can be
      high.  This patch uses a simple structure that tracks CPUs that
      potentially have TLB entries for pages being unmapped.  When the unmapping
      is complete, the full TLB is flushed on the assumption that a refill cost
      is lower than flushing individual entries.

      Architectures wishing to do this must give the following guarantee.

              If a clean page is unmapped and not immediately flushed, the
              architecture must guarantee that a write to that linear address
              from a CPU with a cached TLB entry will trap a page fault.

      This is essentially what the kernel already depends on but the window is
      much larger with this patch applied and is worth highlighting.  The
      architecture should consider whether the cost of the full TLB flush is
      higher than sending an IPI to flush each individual entry.  An additional
      architecture helper called flush_tlb_local is required.  It's a trivial
      wrapper with some accounting in the x86 case.

      The impact of this patch depends on the workload as measuring any benefit
      requires both mapped pages co-located on the LRU and memory pressure.  The
      case with the biggest impact is multiple processes reading mapped pages
      taken from the vm-scalability test suite.  The test case uses NR_CPU
      readers of mapped files that consume 10*RAM.

      This is showing that the readers completed 24.40% faster with 29% less

      test and the patched kernel was interrupts 180K times per second.

      It's still a noticeable improvement with vmstat showing interrupts went
      from roughly 500K per second to 45K per second.

      The patch will have no impact on workloads with no memory pressure or have
      relatively few mapped pages.  It will have an unpredictable impact on the
      workload running on the CPU being flushed as it'll depend on how many TLB
      entries need to be refilled and how long that takes.  Worst case, the TLB
      will be completely cleared of active entries when the target PFNs were not
      resident at all.

      x86, mm: trace when an IPI is about to be sent

      When unmapping pages it is necessary to flush the TLB.  If that page was
      accessed by another CPU then an IPI is used to flush the remote CPU.  That
      is a lot of IPIs if kswapd is scanning and unmapping >100K pages per
      second.

      There already is a window between when a page is unmapped and when it is
      TLB flushed.  This series increases the window so multiple pages can be
      flushed using a single IPI.  This should be safe or the kernel is hosed
      already.

      Patch 1 simply made the rest of the series easier to write as ftrace
              could identify all the senders of TLB flush IPIS.

      Patch 2 tracks what CPUs potentially map a PFN and then sends an IPI
              to flush the entire TLB.

      Patch 3 tracks when there potentially are writable TLB entries that
              need to be batched differently

      Patch 4 increases SWAP_CLUSTER_MAX to further batch flushes

      The performance impact is documented in the changelogs but in the 
optimistic
      case on a 4-socket machine the full series reduces interrupts from 900K
      interrupts/second to 60K interrupts/second.

      This patch (of 4):

      It is easy to trace when an IPI is received to flush a TLB but harder to
      detect what event sent it.  This patch makes it easy to identify the
      source of IPIs being transmitted for TLB flushes on x86.

      userfaultfd: propagate the full address in THP faults

      The THP faults were not propagating the original fault address.  The
      latest version of the API with uffd.arg.pagefault.address is supposed to
      propagate the full address through THP faults.

      This was not a kernel crashing bug and it wouldn't risk to corrupt user
      memory, but it would cause a SIGBUS failure because the wrong page was
      being copied.

      For various reasons this wasn't easily reproducible in the qemu workload,
      but the strestest exposed the problem immediately.

      userfaultfd: allow signals to interrupt a userfault

      This is only simple to achieve if the userfault is going to return to
      userland (not to the kernel) because we can avoid returning VM_FAULT_RETRY
      despite we temporarily released the mmap_sem.  The fault would just be
      retried by userland then.  This is safe at least on x86 and powerpc (the
      two archs with the syscall implemented so far).

      Hint to verify for which archs this is safe: after handle_mm_fault
      returns, no access to data structures protected by the mmap_sem must be
      done by the fault code in arch/*/mm/fault.c until up_read(&mm->mmap_sem)
      is called.

      This has two main benefits: signals can run with lower latency in
      production (signals aren't blocked by userfaults and userfaults are
      immediately repeated after signal processing) and gdb can then trivially
      debug the threads blocked in this kind of userfaults coming directly from
      userland.

      On a side note: while gdb has a need to get signal processed, coredumps
      always worked perfectly with userfaults, no matter if the userfault is
      triggered by GUP a kernel copy_user or directly from userland.

      userfaultfd: require UFFDIO_API before other ioctls

      UFFDIO_API was already forced before read/poll could work.  This makes the
      code more strict to force it also for all other ioctls.

      All users would already have been required to call UFFDIO_API before
      invoking other ioctls but this makes it more explicit.

      This will ensure we can change all ioctls (all but UFFDIO_API/struct
      uffdio_api) with a bump of uffdio_api.api.

      There's no actual plan or need to change the API or the ioctl, the current
      API already should cover fine even the non cooperative usage, but this is
      just for the longer term future just in case.

      These two ioctl allows to either atomically copy or to map zeropages

      userfaultfd: solve the race between UFFDIO_COPY|ZEROPAGE and read

      Solve in-kernel the race between UFFDIO_COPY|ZEROPAGE and
      userfaultfd_read if they are run on different threads simultaneously.

      Until now qemu solved the race in userland: the race was explicitly
      and intentionally left for userland to solve. However we can also
      solve it in kernel.

      Requiring all users to solve this race if they use two threads (one
      for the background transfer and one for the userfault reads) isn't
      very attractive from an API prospective, furthermore this allows to
      remove a whole bunch of mutex and bitmap code from qemu, making it
      faster. The cost of __get_user_pages_fast should be insignificant
      considering it scales perfectly and the pagetables are already hot in
      the CPU cache, compared to the overhead in userland to maintain those
      structures.

      Applying this patch is backwards compatible with respect to the
      userfaultfd userland API, however reverting this change wouldn't be
      backwards compatible anymore.

      Without this patch qemu in the background transfer thread, has to read
      the old state, and do UFFDIO_WAKE if old_state is missing but it
      become REQUESTED by the time it tries to set it to RECEIVED (signaling
      the other side received an userfault).

          vcpu                background_thr userfault_thr
          -----               -----          -----
          vcpu0 handle_mm_fault()

                              postcopy_place_page
                              read old_state -> MISSING
                              UFFDIO_COPY 0x7fb76a139000 (no wakeup, still 
pending)

          vcpu0 fault at 0x7fb76a139000 enters handle_userfault
          poll() is kicked

                                              poll() -> POLLIN
                                              read() -> 0x7fb76a139000
                                              
postcopy_pmi_change_state(MISSING, REQUESTED) -> REQUESTED

                              tmp_state = postcopy_pmi_change_state(old_state, 
RECEIVED) -> REQUESTED
                              /* check that no userfault raced with UFFDIO_COPY 
*/
                              if (old_state == MISSING && tmp_state == 
REQUESTED)
                                      UFFDIO_WAKE from background thread

      And a second case where a UFFDIO_WAKE would be needed is in the userfault 
thread:

          vcpu                background_thr userfault_thr
          -----               -----          -----
          vcpu0 handle_mm_fault()

                              postcopy_place_page
                              read old_state -> MISSING
                              UFFDIO_COPY 0x7fb76a139000 (no wakeup, still 
pending)
                              tmp_state = postcopy_pmi_change_state(old_state, 
RECEIVED) -> RECEIVED

          vcpu0 fault at 0x7fb76a139000 enters handle_userfault
          poll() is kicked

                                              poll() -> POLLIN
                                              read() -> 0x7fb76a139000

                                              if 
(postcopy_pmi_change_state(MISSING, REQUESTED) == RECEIVED)
                                                      UFFDIO_WAKE from 
userfault thread

      This patch removes the need of both UFFDIO_WAKE and of the associated
      per-page tristate as well.

      userfaultfd: wake pending userfaults

      This is an optimization but it's a userland visible one and it affects
      the API.

      The downside of this optimization is that if you call poll() and you
      get POLLIN, read(ufd) may still return -EAGAIN. The blocked userfault
      may be waken by a different thread, before read(ufd) comes
      around. This in short means that poll() isn't really usable if the
      userfaultfd is opened in blocking mode.

      userfaults won't wait in "pending" state to be read anymore and any
      UFFDIO_WAKE or similar operations that has the objective of waking
      userfaults after their resolution, will wake all blocked userfaults
      for the resolved range, including those that haven't been read() by
      userland yet.

      The behavior of poll() becomes not standard, but this obviates the
      need of "spurious" UFFDIO_WAKE and it lets the userland threads to
      restart immediately without requiring an UFFDIO_WAKE. This is even
      more significant in case of repeated faults on the same address from
      multiple threads.

      This optimization is justified by the measurement that the number of
      spurious UFFDIO_WAKE accounts for 5% and 10% of the total
      userfaults for heavy workloads, so it's worth optimizing those away.

      userfaultfd: change the read API to return a uffd_msg

      I had requests to return the full address (not the page aligned one) to
      userland.

      It's not entirely clear how the page offset could be relevant because
      userfaults aren't like SIGBUS that can sigjump to a different place and it
      actually skip resolving the fault depending on a page offset.  There's
      currently no real way to skip the fault especially because after a
      UFFDIO_COPY|ZEROPAGE, the fault is optimized to be retried within the
      kernel without having to return to userland first (not even self modifying
      code replacing the .text that touched the faulting address would prevent
      the fault to be repeated).  Userland cannot skip repeating the fault even
      more so if the fault was triggered by a KVM secondary page fault or any
      get_user_pages or any copy-user inside some syscall which will return to
      kernel code.  The second time FAULT_FLAG_RETRY_NOWAIT won't be set leading
      to a SIGBUS being raised because the userfault can't wait if it cannot
      release the mmap_map first (and FAULT_FLAG_RETRY_NOWAIT is required for
      that).

      Still returning userland a proper structure during the read() on the uffd,
      can allow to use the current UFFD_API for the future non-cooperative
      extensions too and it looks cleaner as well.  Once we get additional
      fields there's no point to return the fault address page aligned anymore
      to reuse the bits below PAGE_SHIFT.

      The only downside is that the read() syscall will read 32bytes instead of
      8bytes but that's not going to be measurable overhead.

      The total number of new events that can be extended or of new future bits
      for already shipped events, is limited to 64 by the features field of the
      uffdio_api structure.  If more will be needed a bump of UFFD_API will be
      required.

      userfaultfd: add new syscall to provide memory externalization

      Once an userfaultfd has been created and certain region of the process
      virtual address space have been registered into it, the thread responsible
      for doing the memory externalization can manage the page faults in
      userland by talking to the kernel using the userfaultfd protocol.

      poll() can be used to know when there are new pending userfaults to be
      read (POLLIN).

      userfaultfd: prevent khugepaged to merge if userfaultfd is armed

      If userfaultfd is armed on a certain vma we can't "fill" the holes with
      zeroes or we'll break the userland on demand paging.  The holes if the
      userfault is armed, are really missing information (not zeroes) that the
      userland has to load from network or elsewhere.

      The same issue happens for wrprotected ptes that we can't just convert
      into a single writable pmd_trans_huge.

      We could however in theory still merge across zeropages if only
      VM_UFFD_MISSING is set (so if VM_UFFD_WP is not set)...  that could be
      slightly improved but it'd be much more complex code for a tiny corner
      case.

      userfaultfd: call handle_userfault() for userfaultfd_missing() faults

      This is where the page faults must be modified to call
      handle_userfault() if userfaultfd_missing() is true (so if the
      vma->vm_flags had VM_UFFD_MISSING set).

      handle_userfault() then takes care of blocking the page fault and
      delivering it to userland.

      The fault flags must also be passed as parameter so the "read|write"
      kind of fault can be passed to userland.

      userfaultfd: linux/Documentation/vm/userfaultfd.txt

      This is the latest userfaultfd patchset.  The postcopy live migration
      feature on the qemu side is mostly ready to be merged and it entirely
      depends on the userfaultfd syscall to be merged as well.  So it'd be great
      if this patchset could be reviewed for merging in -mm.

      Userfaults allow to implement on demand paging from userland and more
      generally they allow userland to more efficiently take control of the
      behavior of page faults than what was available before (PROT_NONE +
      SIGSEGV trap).

      The use cases are:

      1) KVM postcopy live migration (one form of cloud memory
         externalization).

         KVM postcopy live migration is the primary driver of this work:

          
http://blog.zhaw.ch/icclab/setting-up-post-copy-live-migration-in-openstack/
          http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04873.html

      2) postcopy live migration of binaries inside linux containers:

          http://thread.gmane.org/gmane.linux.kernel.mm/132662

      3) KVM postcopy live snapshotting (allowing to limit/throttle the
         memory usage, unlike fork would, plus the avoidance of fork
         overhead in the first place).

         While the wrprotect tracking is not implemented yet, the syscall API is
         already contemplating the wrprotect fault tracking and it's generic 
enough
         to allow its later implementation in a backwards compatible fashion.

      4) KVM userfaults on shared memory. The UFFDIO_COPY lowlevel method
         should be extended to work also on tmpfs and then the
         uffdio_register.ioctls will notify userland that UFFDIO_COPY is
         available even when the registered virtual memory range is tmpfs
         backed.

      5) alternate mechanism to notify web browsers or apps on embedded
         devices that volatile pages have been reclaimed. This basically
         avoids the need to run a syscall before the app can access with the
         CPU the virtual regions marked volatile. This depends on point 4)
         to be fulfilled first, as volatile pages happily apply to tmpfs.

      Even though there wasn't a real use case requesting it yet, it also
      allows to implement distributed shared memory in a way that readonly
      shared mappings can exist simultaneously in different hosts and they
      can be become exclusive at the first wrprotect fault.

      This patch (of 22):

      Add documentation.

      mm/slab.h: fix argument order in cache_from_obj's error message

      While debugging a networking issue, I hit a condition that triggered an
      object to be freed into the wrong kmem cache, and thus triggered the
      warning in cache_from_obj().

      The arguments in the error message are in wrong order: the location
      of the object's kmem cache is in cachep, not s.

      mm/slub: don't wait for high-order page allocation

      Description is almost copied from commit fb05e7a89f50 ("net: don't wait
      for order-3 page allocation").

      I saw excessive direct memory reclaim/compaction triggered by slub.  This
      causes performance issues and add latency.  Slub uses high-order
      allocation to reduce internal fragmentation and management overhead.  But,
      direct memory reclaim/compaction has high overhead and the benefit of
      high-order allocation can't compensate the overhead of both work.

      This patch makes auxiliary high-order allocation atomic.  If there is no
      memory pressure and memory isn't fragmented, the alloction will still
      success, so we don't sacrifice high-order allocation's benefit here.  If
      the atomic allocation fails, direct memory reclaim/compaction will not be
      triggered, allocation fallback to low-order immediately, hence the direct
      memory reclaim/compaction overhead is avoided.  In the allocation failure
      case, kswapd is waken up and trying to make high-order freepages, so
      allocation could success next time.

      Following is the test to measure effect of this patch.

      System: QEMU, CPU 8, 512 MB
      Mem: 25% memory is allocated at random position to make fragmentation.
       Memory-hogger occupies 150 MB memory.

      mm/slub: fix slab double-free in case of duplicate sysfs filename

      sysfs_slab_add() shouldn't call kobject_put at error path: this puts last
      reference of kmem-cache kobject and frees it.  Kmem cache will be freed
      second time at error path in kmem_cache_create().

      For example this happens when slub debug was enabled in runtime and
      somebody creates new kmem cache:

      # echo 1 | tee /sys/kernel/slab/*/sanity_checks
      # modprobe configfs

      "configfs_dir_cache" cannot be merged because existing slab have debug and
      cannot create new slab because unique name ":t-0000096" already taken.

      mm/slub: move slab initialization into irq enabled region

      Initializing a new slab can introduce rather large latencies because most
      of the initialization runs always with interrupts disabled.

      There is no point in doing so.  The newly allocated slab is not visible
      yet, so there is no reason to protect it against concurrent alloc/free.

      Move the expensive parts of the initialization into allocate_slab(), so
      for all allocations with GFP_WAIT set, interrupts are enabled.

      slub: add support for kmem_cache_debug in bulk calls

      Per request of Joonsoo Kim adding kmem debug support.

      I've tested that when debugging is disabled, then there is almost no
      performance impact as this code basically gets removed by the compiler.

      Need some guidance in enabling and testing this.

      slub: initial bulk free implementation

      This implements SLUB specific kmem_cache_free_bulk().  SLUB allocator now
      both have bulk alloc and free implemented.

      Choose to reenable local IRQs while calling slowpath __slab_free().  In
      worst case, where all objects hit slowpath call, the performance should
      still be faster than fallback function __kmem_cache_free_bulk(), because
      local_irq_{disable+enable} is very fast (7-cycles), while the fallback
      invokes this_cpu_cmpxchg() which is slightly slower (9-cycles).
      Nitpicking, this should be faster for N>=4, due to the entry cost of
      local_irq_{disable+enable}.

      Do notice that the save+restore variant is very expensive, this is key to
      why this optimization works.

      slub: improve bulk alloc strategy

      Call slowpath __slab_alloc() from within the bulk loop, as the side-effect
      of this call likely repopulates c->freelist.

      Choose to reenable local IRQs while calling slowpath.

      Saving some optimizations for later.  E.g.  it is possible to extract
      parts of __slab_alloc() and avoid the unnecessary and expensive (37
      cycles) local_irq_{save,restore}.  For now, be happy calling
      __slab_alloc() this lower icache impact of this func and I don't have to
      worry about correctness.

      slub bulk alloc: extract objects from the per cpu slab

      First piece: acceleration of retrieval of per cpu objects

      If we are allocating lots of objects then it is advantageous to disable
      interrupts and avoid the this_cpu_cmpxchg() operation to get these objects
      faster.

      Note that we cannot do the fast operation if debugging is enabled, because
      we would have to add extra code to do all the debugging checks.  And it
      would not be fast anyway.

      Note also that the requirement of having interrupts disabled avoids having
      to do processor flag operations.

      Allocate as many objects as possible in the fast way and then fall back to
      the generic implementation for the rest of the objects.

      slab: infrastructure for bulk object allocation and freeing

      Add the basic infrastructure for alloc/free operations on pointer arrays.
      It includes a generic function in the common slab code that is used in
      this infrastructure patch to create the unoptimized functionality for slab
      bulk operations.

      Allocators can then provide optimized allocation functions for situations
      in which large numbers of objects are needed.  These optimization may
      avoid taking locks repeatedly and bypass metadata creation if all objects
      in slab pages can be used to provide the objects required.

      Allocators can extend the skeletons provided and add their own code to the
      bulk alloc and free functions.  They can keep the generic allocation and
      freeing and just fall back to those if optimizations would not work (like
      for example when debugging is on).

      slub: fix spelling succedd to succeed

      With this patchset the SLUB allocator now has both bulk alloc and free
      implemented.

      This patchset mostly optimizes the "fastpath" where objects are available
      on the per CPU fastpath page.  This mostly amortize the less-heavy
      none-locked cmpxchg_double used on fastpath.

      The "fallback" bulking (e.g __kmem_cache_free_bulk) provides a good basis
      for comparison.  Measurements[1] of the fallback functions
      __kmem_cache_{free,alloc}_bulk have been copied from slab_common.c and
      forced "noinline" to force a function call like slab_common.c.

      Measurements on CPU CPU i7-4790K @ 4.00GHz
      Baseline normal fastpath (alloc+free cost): 42 cycles(tsc) 10.601 ns

      Benchmarking shows impressive improvements in the "fastpath" with a small
      number of objects in the working set.  Once the working set increases,
      resulting in activating the "slowpath" (that contains the heavier locked
      cmpxchg_double) the improvement decreases.

      I'm currently working on also optimizing the "slowpath" (as network stack
      use-case hits this), but this patchset should provide a good foundation
      for further improvements.  Rest of my patch queue in this area needs some
      more work, but preliminary results are good.  I'm attending Netfilter
      Workshop[2] next week, and I'll hopefully return working on further
      improvements in this area.

      This interface can be utilized to deactivate the hard and soft lockup

      watchdog: introduce watchdog_park_threads() and watchdog_unpark_threads()

      Originally watchdog_nmi_enable(cpu) and watchdog_nmi_disable(cpu) were
      only called in watchdog thread context.  However, the following commits
      utilize these functions outside of watchdog thread context too.

            watchdog: Add watchdog enable/disable all functions

      Hence, it is now possible that these functions execute concurrently with
      the same 'cpu' argument.  This concurrency is problematic because per-cpu
      'watchdog_ev' can be accessed/modified without adequate synchronization.

      The patch series aims to address the above problem.  However, instead of
      introducing locks to protect per-cpu 'watchdog_ev' a different approach is
      taken: Invoke these functions by parking and unparking the watchdog
      threads (to ensure they are always called in watchdog thread context).

        static struct smp_hotplug_thread watchdog_threads = {
                 ...
                .park   = watchdog_disable, // calls watchdog_nmi_disable()
                .unpark = watchdog_enable,  // calls watchdog_nmi_enable()
        };

      Both previously mentioned commits call these functions in a similar way
      and thus in principle contain some duplicate code.  The patch series also
      avoids this duplication by providing a commonly usable mechanism.

      - Patch 1/4 introduces the watchdog_{park|unpark}_threads functions that
        park/unpark all watchdog threads specified in 'watchdog_cpumask'. They
        are intended to be called inside of kernel/watchdog.c only.

      - Patch 2/4 introduces the watchdog_{suspend|resume} functions which can
        be utilized by external callers to deactivate the hard and soft lockup
        detector temporarily.

      - Patch 3/4 utilizes watchdog_{park|unpark}_threads to replace some code
        that was introduced by commit 9809b18fcf6b8d8ec4d3643677345907e6b50eca.

      - Patch 4/4 utilizes watchdog_{suspend|resume} to replace some code that
        was introduced by commit b3738d29323344da3017a91010530cf3a58590fc.

      A few corner cases should be mentioned here for completeness.

      - kthread_park() of watchdog/N could hang if cpu N is already locked up.
        However, if watchdog is enabled the lockup will be detected anyway.

      - kthread_unpark() of watchdog/N could hang if cpu N got locked up after
        kthread_park(). The occurrence of this scenario should be _very_ rare
        in practice, in particular because it is not expected that temporary
        deactivation will happen frequently, and if it happens at all it is
        expected that the duration of deactivation will be short.

      This patch (of 4): introduce watchdog_park_threads() and 
watchdog_unpark_threads()

      These functions are intended to be used only from inside kernel/watchdog.c
      to park/unpark all watchdog threads that are specified in
      watchdog_cpumask.

      smpboot: make cleanup to mirror setup

      The per-cpu kthread cleanup() callback is the mirror of the setup()
      callback.  When the per-cpu kthread is started, it first calls setup()
      to initialize the resources which are then released by cleanup() when
      the kthread exits.

      Now since the introduction of a per-cpu kthread cpumask, the kthreads
      excluded by the cpumask on boot may happen to be parked immediately
      after their creation without taking the setup() stage, waiting to be
      asked to unpark to do so.  Then when smpboot_unregister_percpu_thread()
      is later called, the kthread is stopped without having ever called
      setup().

      But this triggers a bug as the kthread unconditionally calls cleanup()
      on exit but this doesn't mirror any setup().  Thus the kernel crashes
      because we try to free resources that haven't been initialized, as in
      the watchdog case:

          WATCHDOG disable 0
          WATCHDOG disable 1
          WATCHDOG disable 2
          BUG: unable to handle kernel NULL pointer dereference at

          IP: hrtimer_active+0x26/0x60

          Call Trace:

            kthread+0xf8/0x110
            ret_from_fork+0x3f/0x70

      This bug is currently masked with explicit kthread unparking before
      kthread_stop() on smpboot_destroy_threads(). This forces a call to
      setup() and then unpark().

      We could fix this by unconditionally calling setup() on kthread entry.
      But setup() isn't always cheap.  In the case of watchdog it launches
      hrtimer, perf events, etc...  So we may as well like to skip it if there
      are chances the kthread will never be used, as in a reduced cpumask value.

      So let's simply do a state machine check before calling cleanup() that
      makes sure setup() has been called before mirroring it.

      And remove the nasty hack workaround.

      fs: create and use seq_show_option for escaping

      Many file systems that implement the show_options hook fail to correctly
      escape their output which could lead to unescaped characters (e.g.  new
      lines) leaking into /proc/mounts and /proc/[pid]/mountinfo files.  This
      could lead to confusion, spoofed entries (resulting in things like
      systemd issuing false d-bus "mount" notifications), and who knows what
      else.  This looks like it would only be the root user stepping on
      themselves, but it's possible weird things could happen in containers or
      in other situations with delegated mount privileges.

      Here's an example using overlay with setuid fusermount trusting the
      contents of /proc/mounts (via the /etc/mtab symlink).  Imagine the use
      of "sudo" is something more sneaky:

        $ BASE="ovl"
        $ MNT="$BASE/mnt"
        $ LOW="$BASE/lower"
        $ UP="$BASE/upper"
        $ WORK="$BASE/work/ 0 0
        none /proc fuse.pwn user_id=1000"
        $ mkdir -p "$LOW" "$UP" "$WORK"
        $ sudo mount -t overlay -o "lowerdir=$LOW,upperdir=$UP,workdir=$WORK" 
none /mnt
        $ cat /proc/mounts
        none /root/ovl/mnt overlay 
rw,relatime,lowerdir=ovl/lower,upperdir=ovl/upper,workdir=ovl/work/ 0 0
        none /proc fuse.pwn user_id=1000 0 0
        $ fusermount -u /proc
        $ cat /proc/mounts
        cat: /proc/mounts: No such file or directory

      This fixes the problem by adding new seq_show_option and
      seq_show_option_n helpers, and updating the vulnerable show_option
      handlers to use them as needed.  Some, like SELinux, need to be open
      coded due to unusual existing escape mechanisms.

      ocfs2: do not set fs read-only if rec[0] is empty while committing 
truncate

      While appending an extent to a file, it will call these functions:
      ocfs2_insert_extent

        -> call ocfs2_grow_tree() if there's no free rec
           -> ocfs2_add_branch add a new branch to extent tree,
              now rec[0] in the leaf of rightmost path is empty
        -> ocfs2_do_insert_extent
           -> ocfs2_rotate_tree_right
             -> ocfs2_extend_rotate_transaction
                -> jbd2_journal_restart if jbd2_journal_extend fail
           -> ocfs2_insert_path
              -> ocfs2_extend_trans
                -> jbd2_journal_restart if jbd2_journal_extend fail
              -> ocfs2_insert_at_leaf
           -> ocfs2_et_update_clusters
      Function jbd2_journal_restart() may be called and it may happened that
      buffers dirtied in ocfs2_add_branch() are committed
      while buffers dirtied in ocfs2_insert_at_leaf() and
      ocfs2_et_update_clusters() are not.
      So an empty rec[0] is left in rightmost path which will cause
      read-only filesystem when call ocfs2_commit_truncate()
      with the error message: "Inode %lu has an empty extent record".

      This is not a serious problem, so remove the rightmost path when call
      ocfs2_commit_truncate().

      ocfs2: call ocfs2_journal_access_di() before ocfs2_journal_dirty() in 
ocfs2_write_end_nolock()

      1: After we call ocfs2_journal_access_di() in ocfs2_write_begin(),
         jbd2_journal_restart() may also be called, in this function transaction
         A's t_updates-- and obtains a new transaction B.  If
         jbd2_journal_commit_transaction() is happened to commit transaction A,
         when t_updates==0, it will continue to complete commit and unfile
         buffer.

         So when jbd2_journal_dirty_metadata(), the handle is pointed a new
         transaction B, and the buffer head's journal head is already freed,
         jh->b_transaction == NULL, jh->b_next_transaction == NULL, it returns
         EINVAL, So it triggers the BUG_ON(status).

          ocfs2_journal_dirty
              jbd2_journal_dirty_metadata(bug)
         ocfs2_commit_trans

      2.  In ext4, I found that: jbd2_journal_get_write_access() called by
         ext4_write_end.

      ext4_write_begin
          ext4_journal_start
              __ext4_journal_start_sb
                  ext4_journal_check_start
                  jbd2__journal_start

      ext4_write_end
          ext4_mark_inode_dirty
              ext4_reserve_inode_write
                  ext4_journal_get_write_access
                      jbd2_journal_get_write_access
              ext4_mark_iloc_dirty
                  ext4_do_update_inode
                      ext4_handle_dirty_metadata
                          jbd2_journal_dirty_metadata

      3. So I think we should put ocfs2_journal_access_di before
         ocfs2_journal_dirty in the ocfs2_write_end.  and it works well after my
         modification.

      ocfs2: use 64bit variables to track heartbeat time

      o2hb_elapsed_msecs computes the time taken for a disk heartbeat.
      'struct timeval' variables are used to store start and end times.  On
      32-bit systems, the 'tv_sec' component of 'struct timeval' will overflow
      in year 2038 and beyond.

      This patch solves the overflow with the following:

      1. Replace o2hb_elapsed_msecs using 'ktime_t' values to measure start
         and end time, and built-in function 'ktime_ms_delta' to compute the
         elapsed time.  ktime_get_real() is used since the code prints out the
         wallclock time.

      2. Changes format string to print time as a single 64-bit nanoseconds
         value ("%lld") instead of seconds and microseconds.  This simplifies
         the code since converting ktime_t to that format would need expensive
         computation.  However, the debug log string is less readable than the
         previous format.

      ocfs2: fix race between crashed dio and rm

      There is a race case between crashed dio and rm, which will lead to

                                        ocfs2_remove_inode
                                        recover N1 and read the corrupted inode,
                                        and set filesystem read-only

      So we skip the inode deletion this time and wait for dio entry recovered
      first.

      ocfs2: avoid access invalid address when read o2dlm debug messages

      The following case will lead to a lockres is freed but is still in use.

      cat /sys/kernel/debug/o2dlm/locking_state dlm_thread
      lockres_seq_start
          -> lock dlm->track_lock
          -> get resA
                                                      resA->refs decrease to 0,
                                                      call dlm_lockres_release,
                                                      and wait for "cat" unlock.
      Although resA->refs is already set to 0,
      increase resA->refs, and then unlock
                                                      lock dlm->track_lock
                                                          -> list_del_init()
                                                          -> unlock
                                                          -> free resA

      In such a race case, invalid address access may occurs.  So we should
      delete list res->tracking before resA->refs decrease to 0.

      inode lock is not held.  This seems to be regression from older kernels.

OCFS2_INODE_UPDATE_CREDITS);

      ocfs2_setattr.#1247 we unlock and at #1259 call posix_acl_chmod. When we 
reach
      ocfs2_acl_set_mode.#181 and do trans, the inode cluster lock is not held 
in EX
      mode (it should be). How this could have happended?

      We are the lock master, were holding lock EX and have released it in
      ocfs2_setattr.#1247.  Note that there are no holders of this lock at
      this point.  Another node needs the lock in PR, and we downconvert from
      EX to PR.  So the inode lock is PR when do the trans in
      ocfs2_acl_set_mode.#184.  The trans stays in core (not flushed to disc).
      Now another node want the lock in EX, downconvert thread gets kicked
      (the one that tripped assert abovt), finds an unflushed trans but the
      lock is not EX (it is PR).  If the lock was at EX, it would have flushed
      the trans ocfs2_ci_checkpointed -> ocfs2_start_checkpoint before
      downconverting (to NULL) for the request.

      ocfs2_setattr must not drop inode lock ex in this code path.  If it
      does, takes it again before the trans, say in ocfs2_set_acl, another
      cluster node can get in between, execute another setattr, overwriting
      the one in progress on this node, resulting in a mode acl size combo
      that is a mix of the two.

      ocfs2: fix a tiny case that inode can not removed

      When running dirop_fileop_racer we found a case that inode
      can not removed.

      Two nodes, say Node A and Node B, mount the same ocfs2 volume.  Create
      two dirs /race/1/ and /race/2/ in the filesystem.

        Node A                            Node B
        rm -r /race/2/
                                          mv /race/1/ /race/2/
        call ocfs2_unlink(), get
        the EX mode of /race/2/
                                          wait for B unlock /race/2/
        decrease i_nlink of /race/2/ to 0,
        and add inode of /race/2/ into
        orphan dir, unlock /race/2/
                                          got EX mode of /race/2/. because
                                          /race/1/ is dir, so inc i_nlink
                                          of /race/2/ and update into disk,
                                          unlock /race/2/
        because i_nlink of /race/2/
        is not zero, this inode will
        always remain in orphan dir

      This patch fixes this case by test whether i_nlink of new dir is zero.

      ocfs2: add ip_alloc_sem in direct IO to protect allocation changes

      In ocfs2, ip_alloc_sem is used to protect allocation changes on the
      node.  In direct IO, we add ip_alloc_sem to protect date consistent
      between direct-io and ocfs2_truncate_file race (buffer io use
      ip_alloc_sem already).  Although inode->i_mutex lock is used to avoid
      concurrency of above situation, i think ip_alloc_sem is still needed
      because protect allocation changes is significant.

      Other filesystem like ext4 also uses rw_semaphore to protect data
      consistent between get_block-vs-truncate race by other means, So
      ip_alloc_sem in ocfs2 direct io is needed.

      ocfs2: add errors=continue

      OCFS2 is often used in high-availaibility systems.  However, ocfs2
      converts the filesystem to read-only at the drop of the hat.  This may
      not be necessary, since turning the filesystem read-only would affect
      other running processes as well, decreasing availability.

      This attempt is to add errors=continue, which would return the EIO to
      the calling process and terminate furhter processing so that the
      filesystem is not corrupted further.  However, the filesystem is not
      converted to read-only.

      As a future plan, I intend to create a small utility or extend
      fsck.ocfs2 to fix small errors such as in the inode.  The input to the
      utility such as the inode can come from the kernel logs so we don't have
      to schedule a downtime for fixing small-enough errors.

      The patch changes the ocfs2_error to return an error.  The error
      returned depends on the mount option set.  If none is set, the default
      is to turn the filesystem read-only.

      Perhaps errors=continue is not the best option name.  Historically it is
      used for making an attempt to progress in the current process itself.
      Should we call it errors=eio? or errors=killproc? Suggestions/Comments
      welcome.

      ocfs2: flush inode data to disk and free inode when i_count becomes zero

      Disk inode deletion may be heavily delayed when one node unlink a file
      after the same dentry is freed on another node(say N1) because of memory
      shrink but inode is left in memory.  This inode can only be freed while
      N1 doing the orphan scan work.

      However, N1 may skip orphan scan for several times because other nodes
      may do the work earlier.  In our tests, it may take 1 hour on 4 nodes
      cluster and it hurts the user experience.  So we think the inode should
      be freed after the data flushed to disk when i_count becomes zero to
      avoid such circumstances.

      ocfs2: set filesytem read-only when ocfs2_delete_entry failed.

      In ocfs2_rename, it will lead to an inode with two entried(old and new) if
      ocfs2_delete_entry(old) failed.  Thus, filesystem will be inconsistent.

      The case is described below:

      ocfs2_rename
          -> ocfs2_start_trans
          -> ocfs2_add_entry(new)
          -> ocfs2_delete_entry(old)
              -> __ocfs2_journal_access *failed* because of -ENOMEM
          -> ocfs2_commit_trans

      So filesystem should be set to read-only at the moment.

                   1) another node may rm the file and then down, this node
                   take care of orphan recovery and clear flag
                   OCFS2_DIO_ORPHANED_FL.
                   2) since rw lock is unlocked, it may race with another
                   orphan recovery and append dio.
          ocfs2_del_inode_from_orphan

      So take inode mutex lock when recovering orphans and make rw unlock at the
      end of aio write in case of append dio.

      scripts: decode_stacktrace: fix ARM architecture decoding

      Fix the stack decoder for the ARM architecture.
      An ARM stack is designed as :

      [   81.547704] [<c023eb04>] (bucket_find_contain) from [<c023ec88>] 
(check_sync+0x40/0x4f8)
      [   81.559668] [<c023ec88>] (check_sync) from [<c023f8c4>] 
(debug_dma_sync_sg_for_cpu+0x128/0x194)
      [   81.571583] [<c023f8c4>] (debug_dma_sync_sg_for_cpu) from [<c0327dec>] 
(__videobuf_s

      The current script doesn't expect the symbols to be bound by
      parenthesis, and triggers the following errors :

        awk: cmd. line:1: error: Unmatched ( or \(: / (check_sync$/
        [   81.547704] (bucket_find_contain) from (check_sync+0x40/0x4f8)

      Fix it by chopping starting and ending parenthesis from the each symbol
      name.

      As a side note, this probably comes from the function
      dump_backtrace_entry(), which is implemented differently for each
      architecture.  That makes a single decoding script a bit a challenge.

      fsnotify_destroy_mark_locked() is subtle to use because it temporarily
      releases group->mark_mutex.  To avoid future problems with this
      function, split it into two.

      fsnotify_detach_mark() is the part that needs group->mark_mutex and
      fsnotify_free_mark() is the part that must be called outside of
      group->mark_mutex.  This way it's much clearer what's going on and we
      also avoid some pointless acquisitions of group->mark_mutex.

      fs/notify: optimize inotify/fsnotify code for unwatched files

      I have a _tiny_ microbenchmark that sits in a loop and writes single
      bytes to a file.  Writing one byte to a tmpfs file is around 2x slower
      than reading one byte from a file, which is a _bit_ more than I expecte.
      This is a dumb benchmark, but I think it's hard to deny that write() is
      a hot path and we should avoid unnecessary overhead there.

      I did a 'perf record' of 30-second samples of read and write.  The top
      item in a diffprofile is srcu_read_lock() from fsnotify().  There are
      active inotify fd's from systemd, but nothing is actually listening to
      the file or its part of the filesystem.

      I *think* we can avoid taking the srcu_read_lock() for the common case
      where there are no actual marks on the file.  This means that there will
      both be nothing to notify for *and* implies that there is no need for
      clearing the ignore mask.

      This patch gave a 13.1% speedup in writes/second on my test, which is an
      improvement from the 10.8% that I saw with the last version.

      drivers/video/concole: add negative dependency for VGA_CONSOLE on ARC

      Architectures which support VGA console must define screen_info
      structurture from "uapi/linux/screen_info.h".  Otherwise undefined
      symbol error occurs.  Usually it's defined in "setup.c" for each
      architecture.

      If an architecture does not support VGA console (ARC's case) there are 2
      ways: define a dummy instance of screen_info or add a negative
      dependency for VGA_CONSOLE in to prevent selecting this option.

      I've implemented the second way.  However the best solution is to add
      HAVE_VGA_CONSOLE option for targets which support VGA console.  Then
      turn off VGA_CONSOLE by default and add dependency to HAVE_VGA_CONSOLE.
      But right now it's better to just add a negative dependency for ARC and
      then consider how to collaborate about this issue with maintainers of
      other architectures.

      capabilities: ambient capabilities

      Credit where credit is due: this idea comes from Christoph Lameter with
      a lot of valuable input from Serge Hallyn.  This patch is heavily based
      on Christoph's patch.

      ===== The status quo =====

      On Linux, there are a number of capabilities defined by the kernel.  To
      perform various privileged tasks, processes can wield capabilities that
      they hold.

      Each task has four capability masks: effective (pE), permitted (pP),
      inheritable (pI), and a bounding set (X).  When the kernel checks for a
      capability, it checks pE.  The other capability masks serve to modify
      what capabilities can be in pE.

      Any task can remove capabilities from pE, pP, or pI at any time.  If a
      task has a capability in pP, it can add that capability to pE and/or pI.
      If a task has CAP_SETPCAP, then it can add any capability to pI, and it
      can remove capabilities from X.

      Tasks are not the only things that can have capabilities; files can also
      have capabilities.  A file can have no capabilty information at all [1].
      If a file has capability information, then it has a permitted mask (fP)
      and an inheritable mask (fI) as well as a single effective bit (fE) [2].
      File capabilities modify the capabilities of tasks that execve(2) them.

      A task that successfully calls execve has its capabilities modified for
      the file ultimately being excecuted (i.e.  the binary itself if that
      binary is ELF or for the interpreter if the binary is a script.) [3] In
      the capability evolution rules, for each mask Z, pZ represents the old
      value and pZ' represents the new value.  The rules are:

        pP' = (X & fP) | (pI & fI)
        pI' = pI
        pE' = (fE ? pP' : 0)
        X is unchanged

      For setuid binaries, fP, fI, and fE are modified by a moderately
      complicated set of rules that emulate POSIX behavior.  Similarly, if
      euid == 0 or ruid == 0, then fP, fI, and fE are modified differently
      (primary, fP and fI usually end up being the full set).  For nonroot
      users executing binaries with neither setuid nor file caps, fI and fP
      are empty and fE is false.

      As an extra complication, if you execute a process as nonroot and fE is
      set, then the "secure exec" rules are in effect: AT_SECURE gets set,
      LD_PRELOAD doesn't work, etc.

      This is rather messy.  We've learned that making any changes is
      dangerous, though: if a new kernel version allows an unprivileged
      program to change its security state in a way that persists cross
      execution of a setuid program or a program with file caps, this
      persistent state is surprisingly likely to allow setuid or file-capped
      programs to be exploited for privilege escalation.

      ===== The problem =====

      Capability inheritance is basically useless.

      If you aren't root and you execute an ordinary binary, fI is zero, so
      your capabilities have no effect whatsoever on pP'.  This means that you
      can't usefully execute a helper process or a shell command with elevated
      capabilities if you aren't root.

      On current kernels, you can sort of work around this by setting fI to
      the full set for most or all non-setuid executable files.  This causes
      pP' = pI for nonroot, and inheritance works.  No one does this because
      it's a PITA and it isn't even supported on most filesystems.

      If you try this, you'll discover that every nonroot program ends up with
      secure exec rules, breaking many things.

      This is a problem that has bitten many people who have tried to use
      capabilities for anything useful.

      ===== The proposed change =====

      This patch adds a fifth capability mask called the ambient mask (pA).
      pA does what most people expect pI to do.

      pA obeys the invariant that no bit can ever be set in pA if it is not
      set in both pP and pI.  Dropping a bit from pP or pI drops that bit from
      pA.  This ensures that existing programs that try to drop capabilities
      still do so, with a complication.  Because capability inheritance is so
      broken, setting KEEPCAPS, using setresuid to switch to nonroot uids, and
      then calling execve effectively drops capabilities.  Therefore,
      setresuid from root to nonroot conditionally clears pA unless
      SECBIT_NO_SETUID_FIXUP is set.  Processes that don't like this can
      re-add bits to pA afterwards.

      The capability evolution rules are changed:

        pA' = (file caps or setuid or setgid ? 0 : pA)
        pP' = (X & fP) | (pI & fI) | pA'
        pI' = pI
        pE' = (fE ? pP' : pA')
        X is unchanged

      If you are nonroot but you have a capability, you can add it to pA.  If
      you do so, your children get that capability in pA, pP, and pE.  For
      example, you can set pA = CAP_NET_BIND_SERVICE, and your children can
      automatically bind low-numbered ports.  Hallelujah!

      Unprivileged users can create user namespaces, map themselves to a
      nonzero uid, and create both privileged (relative to their namespace)
      and unprivileged process trees.  This is currently more or less
      impossible.  Hallelujah!

      You cannot use pA to try to subvert a setuid, setgid, or file-capped
      program: if you execute any such program, pA gets cleared and the
      resulting evolution rules are unchanged by this patch.

      Users with nonzero pA are unlikely to unintentionally leak that
      capability.  If they run programs that try to drop privileges, dropping
      privileges will still work.

      It's worth noting that the degree of paranoia in this patch could
      possibly be reduced without causing serious problems.  Specifically, if
      we allowed pA to persist across executing non-pA-aware setuid binaries
      and across setresuid, then, naively, the only capabilities that could
      leak as a result would be the capabilities in pA, and any attacker
      *already* has those capabilities.  This would make me nervous, though --
      setuid binaries that tried to privilege-separate might fail to do so,
      and putting CAP_DAC_READ_SEARCH or CAP_DAC_OVERRIDE into pA could have
      unexpected side effects.  (Whether these unexpected side effects would
      be exploitable is an open question.) I've therefore taken the more
      paranoid route.  We can revisit this later.

      An alternative would be to require PR_SET_NO_NEW_PRIVS before setting
      ambient capabilities.  I think that this would be annoying and would
      make granting otherwise unprivileged users minor ambient capabilities
      (CAP_NET_BIND_SERVICE or CAP_NET_RAW for example) much less useful than
      it is with this patch.

      ===== Footnotes =====

      [1] Files that are missing the "security.capability" xattr or that have
      unrecognized values for that xattr end up with has_cap set to false.
      The code that does that appears to be complicated for no good reason.

      [2] The libcap capability mask parsers and formatters are dangerously
      misleading and the documentation is flat-out wrong.  fE is *not* a mask;
      it's a single bit.  This has probably confused every single person who
      has tried to use file capabilities.

      [3] Linux very confusingly processes both the script and the interpreter
      if applicable, for reasons that elude me.  The results from thinking
      about a script's file capabilities and/or setuid bits are mostly
      discarded.

      Preliminary userspace code is here, but it needs updating:
      
https://git.kernel.org/cgit/linux/kernel/git/luto/util-linux-playground.git/commit/?h=cap_ambient&id=7f5afbd175d2

      Here is a test program that can be used to verify the functionality
      (from Christoph):

      /*
       * Test program for the ambient capabilities. This program spawns a shell
       * that allows running processes with a defined set of capabilities.
       *
       * (C) 2015 Christoph Lameter <cl@xxxxxxxxx>
       * Released under: GPL v3 or later.
       *
       *
       * Compile using:
       *
       *        gcc -o ambient_test ambient_test.o -lcap-ng
       *
       * This program must have the following capabilities to run properly:
       * Permissions for CAP_NET_RAW, CAP_NET_ADMIN, CAP_SYS_NICE
       *
       * A command to equip the binary with the right caps is:
       *
       *        setcap cap_net_raw,cap_net_admin,cap_sys_nice+p ambient_test
       *
       *
       * To get a shell with additional caps that can be inherited by other 
processes:
       *
       *        ./ambient_test /bin/bash
       *
       *
       * Verifying that it works:
       *
       * From the bash spawed by ambient_test run
       *
       *        cat /proc/$$/status
       *
       * and have a look at the capabilities.

      - Make it clear that the `node' arg refers to memory allocations only:
        kthread_create_on_node() does not pin the new thread to that node's
        CPUs.

      - Encourage the use of NUMA_NO_NODE.

      mm: check if section present during memory block registering

      Tony Luck found on his setup, if memory block size 512M will cause crash
      during booting.

      The system has non continuous RAM address:
       BIOS-e820: [mem 0x0000001300000000-0x0000001cffffffff] usable

      So there are start sections in memory block not present.  For example:

          memory block : [0x2c18000000, 0x2c20000000) 512M

      first three sections are not present.

      The current register_mem_sect_under_node() assume first section is
      present, but memory block section number range [start_section_nr,
      end_section_nr] would include not present section.

      For arch that support vmemmap, we don't setup memmap for struct page
      area within not present sections area.

      So skip the pfn range that belong to absent section.

      memory-hotplug: add hot-added memory ranges to memblock before allocate 
node_data for a node.

      Commit f9126ab9241f ("memory-hotplug: fix wrong edge when hot add a new
      node") hot-added memory range to memblock, after creating pgdat for new
      node.

      But there is a problem:

        add_memory()
        |--> hotadd_new_pgdat()
             |--> free_area_init_node()
                  |--> get_pfn_range_for_nid()
                       |--> find start_pfn and end_pfn in memblock
        |--> ......
        |--> memblock_add_node(start, size, nid)    --------    Here, just too 
late.

      get_pfn_range_for_nid() will find that start_pfn and end_pfn are both 0.
      As a result, when adding memory, dmesg will give the following wrong
      message.

        Initmem setup node 5 [mem 0x0000000000000000-0xffffffffffffffff]
        On node 5 totalpages: 0
        Built 5 zonelists in Node order, mobility grouping on.  Total pages: 
32588823
        Policy zone: Normal
        init_memory_mapping: [mem 0x60000000000-0x607ffffffff]

      The solution is simple, just add the memory range to memblock a little
      earlier, before hotadd_new_pgdat().

      CRIS: fix switch_mm() lockdep splat

      With lockdep support implemented on CRISv32, we get the following splat.
      switch_mm() can be called both from the scheduler() (with interrupts
      disabled) and from flush_old_exec (via activate_mm()), with interrupts
      enabled.  Fix it by disabling interrupts in activate_mm(), similar to
      powerpc and hexagon.

              drop fb panic handling, this was just getting more broken, as 
more locking was required.
              new core fbdev Kconfig support - instead of each driver 
enable/disabling it
              struct_mutex cleanups

      Revert "NFS: Make close(2) asynchronous when closing NFS O_DIRECT files"

      This reverts commit f895c53f8ace3c3e49ebf9def90e63fc6d46d2bf.

      This commit causes a NFSv4 regression in that close()+unlink() can end
      up failing. The reason is that we no longer have a guarantee that the
      CLOSE has completed on the server, meaning that the subsequent call to
      REMOVE may fail with NFS4ERR_FILE_OPEN if the server implements Windows
      unlink() semantics.

      Pull sound updates from Takashi Iwai:
       "There are little changes in core part, but lots of development are
        found in drivers, especially ASoC.  The diffstat shows regmap-related
        changes for a slight API additions / changes, and that's all.

        Looking at the code size statistics, the most significant addition is
        for Intel Skylake.  (Note that SKL support is still underway, the
        codec driver is missing.) Also STI controller driver is a major
        addition as well as a few new codec drivers.

        In HD-audio side, there are fewer changes than the past.  The
        noticeable change is the support of ELD notification from i915
        graphics driver.  Thus this pull request carries a few changes in
        drm/i915.

        Other than that, USB-audio got a rewrite of runtime PM code.  It was
        initiated by lockdep warning, but resulted in a good cleanup in the
        end.

        Below are the highlights:

        Common:
         - Factoring out of AC'97 reset code from ASoC into the core helper
         - A few regmap API extensions (in case it's not pulled yet)

        ASoC:
         - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
           RT298 and ST STI controllers
         - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
           RT5650
         - Initial driver support for Intel Skylake devices
         - Lots of rsnd cleanup and enhancements
         - A few DAPM fixes and cleanups
         - A large number of cleanups in various drivers (conversion and
           standardized to regmap, component) mostly by Lars-Peter and Axel

        HD-audio:
         - Extended HD-audio core for Intel Skylake controller support
         - Quirks for Dell headsets, Alienware 15
         - Clean up of pin-based quirk tables for Realtek codecs
         - ELD notifier implenetation for Intel HDMI/DP

         - Refactor runtime PM code to make lockdep happier"

         - mvxor fixes

      [ The Kconfig and Makefile entries got re-sorted alphabetically, and I
        handled the conflict with the new Intel integrated IDMA driver by
        slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
        order to keep the Intel entries together.  I think it might be a good
        idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
        the sorting be a true sort, not this mismash.

        Also, this merge disables the COMPILE_TEST for the sun4i DMA
        controller, because it does not compile cleanly at all.     - Linus ]

       "This is the bulk of pin control changes for the v4.3 development
        cycle.

        Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
        the overall tempo of the kernel v4.3 will be a gigantic diff.

      [ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
        we'll see - Linus ]

        Core changes:

         - It is possible configure groups in debugfs.

         - Consolidation of chained IRQ handler install/remove replacing all
           call sites where irq_set_handler_data() and
           irq_set_chained_handler() were done in succession with a combined
           call to irq_set_chained_handler_and_data().  This series was
           created by Thomas Gleixner after the problem was observed by
           Russell King.

         - Tglx also made another series of patches switching
           __irq_set_handler_locked() for irq_set_handler_locked() which is
           way cleaner.

         - Tglx also wrote a good bunch of patches to make use of
           irq_desc_get_xxx() accessors and avoid looking up irq_descs from
           IRQ numbers.  The goal is to get rid of the irq number from the
           handlers in the IRQ flow which is nice.

        Driver feature enhancements:

         - Power management support for the SiRF SoC Atlas 7.

         - Power down support for the Qualcomm driver.

         - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
           in IRQ handlers to play nice with the realtime patch set.

         - Rework and new modes handling for Qualcomm SPMI-MPP.

         - Pinconf power source config for SH PFC.

        New drivers and subdrivers:

         - A new driver for Conexant Digicolor CX92755.

         - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
           ProXtream2 and PH1-LD6b SoC pin control support.

         - Reverse-egineered the S/PDIF settings for the Allwinner sun4i
           driver.

         - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs

         - A new Freescale i.mx6ul subdriver.

        Cleanup:

         - Remove platform data support in a number of SH PFC subdrivers"

      Merge tag 'gpio-v4.3-1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.3 kernel cycle.

        There is quite a lot going on in the GPIO subsystem this merge window,
        so the main matter is decribed below.

        The hits in other subsystems when making the GPIO flags optional are
        all ACKed by their respective subsystem maintainers.

        Core changes:

         - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
           of the descriptor calls that did not use the flags argument on the
           end.  This was around for too long and eventually Uwe Kleine-König
           took the time to clean it out and the last users are removed along
           with the macros in this tag.  In several cases the use of flags
           simplifies the code.  For this reason we have (ACKed) patches
           hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
           nail with removing the macros.

         - Add a fat document describing how much ready-made GPIO stuff we
           have i the kernel to discourage people from reinventing a square
           wheel in userspace, as so often happens.

         - Create a separate lockdep class for each instance of a GPIO IRQ
           chip instead of using one class for all chips, as the current code
           will not work with systems with several GPIO chips doing lockdep
           debugging.

         - Protect against driver unloading also when a GPIO line is only used
           as IRQ for the GPIOLIB_IRQCHIP helpers.

         - If the GPIO chip has no designated owner, assign the parent device
           driver owner as owner.

         - Consolidation of chained IRQ handler install/remove replacing all
           call sites where irq_set_handler_data() and
           irq_set_chained_handler() were done in succession with a combined
           call to irq_set_chained_handler_and_data().

           This series was created by Thomas Gleixner after the problem was
           observed by Russell King.

         - Tglx also made another series of patches switching
           __irq_set_handler_locked() for irq_set_handler_locked() which is
           way cleaner.

         - Tglx and Jiang Liu wrote a good bunch of patches to make use of
           irq_desc_get_xxx() accessors and avoid looking up irq_descs from
           IRQ numbers.  The goal is to get rid of the irq number from the
           handlers in the IRQ flow which is nice.

         - Rob Herring killed off the set_irq_flags() for all GPIO drivers.
           This was an ARM specific function that is replaced with the generic
           irq_modify_status() where special flags are actually needed.

         - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
           if the pin controller isn't available.  Pretty logical, yet needed
           to be fixed.

         - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
           back, then call these instead of the defaults provided by the
           GPIOLIB.

         - Fix an undocumented ABI hole: named GPIOs were not properly
           documented.

        Driver improvements:

         - Add get_direction() support to the generic GPIO driver, it's
           strange that we didn't have that before.

         - Make it possible to have input-only GPIO chips using the generic
           GPIO driver.

         - Clean out platform data support from the Emma Mobile (EM) driver

         - Finegrained runtime PM support for the RCAR driver.

         - Support r8a7795 (R-car H3) in the RCAR driver.

         - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.

         - Some consolidation and new support in the MPC8xxx driver, we now
           support MPC5125.

         - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
           spinlocks making it work better with the realime patches.

         - Interrupt support for the EXTRAXFS GPIO driver.

         - Make the ETRAXFS GPIO driver support also ARTPEC-3.

         - Interrupt and wakeup support for the BRCMSTB driver, also for
           wakeup from S5 cold boot.

         - Mask MXC IRQs during suspend.

         - Improve OMAP2 GPIO set_debounce() to work according to spec.

         - The VF610 driver handles IRQs properly.

        New drivers:

      arm/arm64: KVM: vgic: Move active state handling to flush_hwstate

      We currently set the physical active state only when we *inject* a new
      pending virtual interrupt, but this is actually not correct, because we
      could have been preempted and run something else on the system that
      resets the active state to clear.  This causes us to run the VM with the
      timer set to fire, but without setting the physical active state.

      The solution is to always check the LR configurations, and we if have a
      mapped interrupt in the LR in either the pending or active state
      (virtual), then set the physical active state.

           automatically

       - Move our PSCI implementation out into drivers/firmware/, where it can
         be shared with arch/arm/. RMK has also pulled this component branch
         and has additional patches moving arch/arm/ over. MAINTAINERS is
         updated accordingly.

       - Better BUG implementation based on the BRK instruction for trapping

       - Leaf TLB invalidation for unmapping user pages

      mac80211: protect non-HT BSS when HT TDLS traffic exists

      HT TDLS traffic should be protected in a non-HT BSS to avoid
      collisions. Therefore, when TDLS peers join/leave, check if
      protection is (now) needed and set the ht_operation_mode of
      the virtual interface according to the HT capabilities of the
      TDLS peer(s).

      This works because a non-HT BSS connection never sets (or
      otherwise uses) the ht_operation_mode; it just means that
      drivers must be aware that this field applies to all HT
      traffic for this virtual interface, not just the traffic
      within the BSS. Document that.

      mac80211: Do not use sizeof() on pointer type

      The rate_control_cap_mask() function takes a parameter mcs_mask, which
      GCC will take to be u8 * even though it was declared with a fixed size.
      This causes the following warning:

        net/mac80211/rate.c: In function 'rate_control_cap_mask':
        net/mac80211/rate.c:719:25: warning: 'sizeof' on array function 
parameter 'mcs_mask' will return size of 'u8 * {aka unsigned char *}' 
[-Wsizeof-array-argument]

                  ^

      This can be easily fixed by using the IEEE80211_HT_MCS_MASK_LEN directly

      We cannot detect clang before including the arch Makefile, because that

      deb-pkg: add source package

      Make deb-pkg build both source and binary package like make rpm-pkg does.
      For people who only need binary kernel package, there is now bindeb-pkg
      target, same target also used to build the .deb files if built from the
      source package using dpkg-buildpackage.

      Generated source package will build the same kernel .config than what
      was available for make deb-pkg. The name of the source package can
      be set with KDEB_SOURCENAME enviroment variable.

      The source package is useful for GPL compliance, or for feeding to a
      automated debian package builder.

      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

        - In some cases where perf_event.fork.{pid,tid} should be used we were 
instead
          using perf_event.comm.{pid,tid}, which is not a problem for for the 
'pid'
          case, that sits in the same place in these union_perf_event members, 
but
          comm.tid sits where fork.ppid is, oops.

          These cases were considered as (potentially) problematic:

           - 'perf script' with !sample_id_all, i.e. only non old kernels 
without
              perf_event_attr.sample_id_all.

           - intel_pt could be affected when decoding without timestamps, as 
the exit
             event is only used to flush out data which anyway gets flushed at 
the
             end of the session.

           - intel_bts also uses the exit event to flush data which would 
probably not
             cause errors as it would get flushed at the end of the session 
instead.

          Fix it. (Adrian Hunter)

        - Due to relaxing the compiler checks for bison generated files, we

      Input: evdev - do not report errors form flush()

      We've got bug reports showing the old systemd-logind (at least
      system-210) aborting unexpectedly, and this turned out to be because
      of an invalid error code from close() call to evdev devices.  close()
      is supposed to return only either EINTR or EBADFD, while the device
      returned ENODEV.  logind was overreacting to it and decided to kill
      itself when an unexpected error code was received.  What a tragedy.

      The bad error code comes from flush fops, and actually evdev_flush()
      returns ENODEV when device is disconnected or client's access to it is
      revoked. But in these cases the fact that flush did not actually happen is
      not an error, but rather normal behavior. For non-disconnected devices
      result of flush is also not that interesting as there is no potential of
      data loss and even if it fails application has no way of handling the
      error. Because of that we are better off always returning success from
      evdev_flush().

      Also returning EINTR from flush()/close() is discouraged (as it is not
      clear how application should handle this error), so let's stop taking
      evdev->mutex interruptibly.

         and removes unnecessary codes, and considers multiple plane format
         of framebuffer. I hope this not to be late.

      security/device_cgroup: Fix RCU_LOCKDEP_WARN() condition

      f78f5b90c4ff ("rcu: Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN()")
      introduced a bug by incorrectly inverting the condition when moving from
      rcu_lockdep_assert() to RCU_LOCKDEP_WARN().  This commit therefore fixes
      the inversion.

      Pull MIPS updates from Ralf Baechle:
       "This is the main pull request for 4.3 for MIPS.  Here's the summary:

        Three fixes that didn't make 4.2-stable:

         - a -Os build might compile the kernel using the MIPS16 instruction
           set but the R2 optimized inline functions in <uapi/asm/swab.h> are
           implemented using 32-bit wide instructions which is invalid.

         - a build error in pgtable-bits.h for a particular kernel
           configuration.

         - accessing registers of the CM GCR might have been compiled to use
           64 bit accesses but these registers are onl 32 bit wide.

        And also a few new bits:

         - move the ATH79 GPIO driver to drivers/gpio

         - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
           change ATH79 accordingly.

         - fix definition of pgprot_writecombine

         - add an implementation of dma_map_ops.mmap

         - fix alignment of quiet build output for vmlinuz link

         - BCM47xx: Use kmemdup rather than duplicating its implementation

         - Netlogic: Fix 0x0x prefixes of constants.

         - merge Bjorn Helgaas' series to remove most of the weak keywords
           from function declarations.

         - CP0 and CP1 registers are best considered treated as unsigned
           values to avoid large values from becoming negative values.

         - improve support for the MIPS GIC timer.

         - enable common clock framework for Malta and SEAD3.

         - a number of improvments and fixes to dump_tlb().

         - document the MIPS TLB dump functionality in Magic SysRq.

         - Cavium Octeon CN68XX improvments.

         - NetLogic improvments.

         - irq: Use access helper irq_data_get_affinity_mask.

         - handle MSA unaligned accesses.

         - a number of R6-related math-emu fixes.

         - support for I6400.

         - improvments to MSA support.

         - add uprobes support.

         - move from deprecated __initcall to arch_initcall.

         - remove finish_arch_switch().

         - IRQ cleanups by Thomas Gleixner.

         - migrate to new 'set-state' interface.

         - random small cleanups"

      Pull locking and atomic updates from Ingo Molnar:
       "Main changes in this cycle are:

         - Extend atomic primitives with coherent logic op primitives
           (atomic_{or,and,xor}()) and deprecate the old partial APIs
           (atomic_{set,clear}_mask())

           The old ops were incoherent with incompatible signatures across
           architectures and with incomplete support.  Now every architecture
           supports the primitives consistently (by Peter Zijlstra)

         - Generic support for 'relaxed atomics':

             - _acquire/release/relaxed() flavours of xchg(), cmpxchg() and 
{add,sub}_return()
             - atomic_read_acquire()
             - atomic_set_release()

           This came out of porting qwrlock code to arm64 (by Will Deacon)

         - Clean up the fragile static_key APIs that were causing repeat bugs,
           by introducing a new one:

             DEFINE_STATIC_KEY_TRUE(name);
             DEFINE_STATIC_KEY_FALSE(name);

           which define a key of different types with an initial true/false
           value.

           Then allow:

             static_branch_likely()
             static_branch_unlikely()

           to take a key of either type and emit the right instruction for the
           case.  To be able to know the 'type' of the static key we encode it
           in the jump entry (by Peter Zijlstra)

         - Static key self-tests (by Jason Baron)

         - qrwlock optimizations (by Waiman Long)

         - small futex enhancements (by Davidlohr Bueso)

      Merge branch 'sctp-fixes'

      Marcelo Ricardo Leitner says:

      ====================
      couple of sctp fixes for 0ca50d12fe46

      These are two fixes for sctp after my patch on 0ca50d12fe46 ("sctp: fix
      src address selection if using secondary addresses")

      The first, fix a dst leak on those it decided to skip.

      The second, adds the fallback on src selection that Vlad had asked
      about. Unfortunatelly a lot of ipvs setups relies on the old behavior
      and I don't see a better fix for it.

      Please consider both to -stable tree.

      sctp: add routing output fallback

      Commit 0ca50d12fe46 added a restriction that the address must belong to
      the output interface, so that sctp will use the right interface even
      when using secondary addresses.

      But it breaks IPVS setups, on which people is used to attach VIP
      addresses to loopback interface on real servers. It's preferred to
      attach to the interface actually in use, but it's a very common setup
      and that used to work.

      This patch then saves the first routing good result, even if it would be
      going out through an interface that doesn't have that address. If no
      better hit found, it's then used. This effectively restores the original
      behavior if no better interface could be found.

      We expect send only joins to fail, it just means there are no listeners
      for the group. The correct thing to do is silently drop the packet
      at source.

      Eg avahi will full join 224.0.0.251 which causes a send only IGMP packet
      to 224.0.0.22, and then a warning level kmessage like this:

      Received handlers defined as ipmi_recv_hndl member of struct
      ipmi_user_hndl can take a spinlock.  This means that if the kernel

      while flushing queued messages in the panic context.

      Calling the receive handler doesn't make much meanings in the panic

      ipmi: Avoid touching possible corrupted lists in the panic context

      When processing queued messages in the panic context, IPMI driver
      tries to do it without any locking to avoid deadlocks.  However,
      this means we can touch a corrupted list if the kernel panicked
      while manipulating the list.  Fortunately, current `add-tail and
      del-from-head' style implementation won't touch the corrupted part,
      but it is inherently risky.

      To get rid of the risk, this patch re-initializes the message lists
      on panic if the related spinlock has already been acquired.  As the
      result, we may lose queued messages, but it's not so painful.
      Dropping messages on the received message list is also less
      problematic because no one can respond the received messages.

      ipmi: Don't flush messages in sender() in run-to-completion mode

      When flushing queued messages in run-to-completion mode,
      smi_event_handler() is recursively called.

      flush_messages()
       smi_event_handler()
        handle_transaction_done()
         deliver_recv_msg()
          ipmi_smi_msg_received()
           smi_recv_tasklet()
            sender()
             flush_messages()
              smi_event_handler()
               ...

      The depth of the recursive call depends on the number of queued
      messages, so it can cause a stack overflow if many messages have
      been queued.

      To solve this problem, this patch removes flush_messages()
      from sender()@ipmi_si_intf.c.  Instead, add flush_messages() to
      caller side of sender() if needed.  Additionally, to implement this,
      add new handler flush_messages to struct ipmi_smi_handlers.

      ipmi: Convert the IPMI SI ACPI handling to a platform device

      The IPMI SI driver was using direct PNP, but that was not really
      ideal because the IPMI device is a platform device.  There was
      some special handling in the acpi_pnp.c code for making this work,
      but that was breaking ACPI handling for the IPMI SSIF driver.

      So without this patch there were significant issues getting the
      SSIF driver to work with ACPI.

      So use a platform device for ACPI detection and remove the
      entry from acpi_pnp.c.

      IB/srp: Fix possible protection fault

      srp_destroy_qp is designed to indicate we are safe to continue with
      freeing the channel resources by modifying the qp error state,
      posting a dummy wr on the queue-pair and waiting for it to flush.
      This also holds for the channel registration pool as we are unmapping
      the memory region when handling a scsi response. Destroying the
      channel registration pool before we make sure we processed all the
      inflight IO might introduce a use-after-free of the registration pool.

      This use-after-free is demonstrated in the stack trace below where
      srp is trying to unmap a used FMR after the fmr_pool was already 
destroyed.

      optimize_nops() is buggy in two aspects:

      mlx5: Fix incorrect wc pkey_index assignment for GSI messages

      Since patch series "Demux IB CM requests in the rdma_cm module" the
      P_Key index is taken from the work completion rather than the message
      itself.

      The HCA provides us with the message P_Key. In order to provide the
      P_Key index, we need to look it up. Given that this is relevant only
      for GSI messages (session establishments) which is less performance 
critical,
      micro-optimize against the GSI (is_qp1) branch.

      clk: Hi6220: separately build stub clock driver

      The previous code, kernel builds Hi6220's common clock driver and stub
      clock driver together. Stub clock driver has introduced the dependency
      with CONFIG_MAILBOX, so kernel will not build Hi6220's common clock
      driver due ARM64's defconfig have not enabled CONFIG_MAILBOX by default.

      So separately build stub clock driver and common clock driver for
      Hi6220; and only let stub clock driver has the dependency with
      CONFIG_MAILBOX.

      While looking at use cases of the wake queues in order to add support

      wake_up_interruptible_nr(), and that use was doing a single task wake
      up. Have that user use the proper wake_up_interruptible() instead, and
      perhaps we can even remove the function wake_up_interruptible_nr().

        rumblings that the lightweight tunnels infrastructure has been voted
        networking change of the year.  But what do I know?

         1) Add conntrack support to openvswitch, from Joe Stringer.

         2) Initial support for VRF (Virtual Routing and Forwarding), which
            allows the segmentation of routing paths without using multiple
            devices.  There are some semantic kinks to work out still, but
            this is a reasonably strong foundation.  From David Ahern.

         3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov.

         4) Ignore route nexthops with a link down state in ipv6, just like
            ipv4.  From Andy Gospodarek.

         5) Remove spinlock from fast path of act_gact and act_mirred, from
            Eric Dumazet.

         6) Document the DSA layer, from Florian Fainelli.

         7) Add netconsole support to bcmgenet, systemport, and DSA.  Also
            from Florian Fainelli.

         8) Add Mellanox Switch Driver and core infrastructure, from Jiri
            Pirko.

         9) Add support for "light weight tunnels", which allow for
            encapsulation and decapsulation without bearing the overhead of a
            full blown netdevice.  From Thomas Graf, Jiri Benc, and a cast of
            others.

        10) Add Identifier Locator Addressing support for ipv6, from Tom
            Herbert.

        11) Support fragmented SKBs in iwlwifi, from Johannes Berg.

        12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia.

        13) Add BQL support to 3c59x driver, from Loganaden Velvindron.

        14) Stop using a zero TX queue length to mean that a device shouldn't
            have a qdisc attached, use an explicit flag instead.  From Phil
            Sutter.

        15) Use generic geneve netdevice infrastructure in openvswitch, from
            Pravin B Shelar.

        16) Add infrastructure to avoid re-forwarding a packet in software
            that was already forwarded by a hardware switch.  From Scott
            Feldman.

        17) Allow AF_PACKET fanout function to be implemented in a bpf
            program, from Willem de Bruijn"

      vram access up front.  This avoids unecessary migrations and
      avoids using visible vram for buffers were it's not needed.

      v2: line wrap fixes

      ring-buffer: Revert "ring-buffer: Get timestamp after event is allocated"

      The commit a4543a2fa9ef31 "ring-buffer: Get timestamp after event is
      allocated" is needed for some future work. But after adding it, there is a
      race somewhere that causes the saved timestamp to have a slight shift, and
      get ahead of the actual timestamp and make it look like time goes 
backwards.

      I'm still looking into why this happens, but in the mean time, this is
      holding up other work to get in. I'm reverting the change for now (which
      makes the problem go away), and will add it back after I know what is 
wrong
      and fix it.

      MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.

      The nomips16 has to be added both as function attribute and assembler
      directive.

      When only function attribute is specified, the compiler will inline the
      function with -Os optimization.  The generated assembly code cannot be
      correctly assembled because ISA mode switch has to be done through jump
      instruction.

      When only ".set nomips16" directive is used, the generated assembly code
      will use MIPS32 code for the inline assembly template and MIPS16 for the
      function return.  The compiled binary is invalid:

          00403100 <__arch_swab16>:
            403100:   7c0410a0    wsbh    v0,a0
            403104:   e820ea31    swc2    $0,-5583(at)

      while correct code should be:

          00402650 <__arch_swab16>:
            402650:   7c0410a0    wsbh    v0,a0

      If the comparison specified by the condn field of the instruction
      is true for the operand values, the result is true; otherwise, the
      result is false. If no exception is taken, the result is written into

      of fmt. All other bits beyond the operand width fmt are UNPREDICTABLE.

      STAGING: Octeon: Support CN68XX style WQE

      CN68XX has a bit different WQE structure. This patch provides the new
      definitions and converts the code to use the proper variant based on
      the actual model.

      CLOCKSOURCE: Add Pistachio clocksource-only driver

      The Pistachio SoC provides four general purpose timers, and allow
      to implement a clocksource driver.

      This driver can be used as a replacement for the MIPS GIC and MIPS R4K
      clocksources and sched clocks, which are clocked from the CPU clock.

      Given the general purpose timers are clocked from an independent clock,
      this new clocksource driver will be useful to introduce CPUFreq support
      for Pistachio machines.

      For the clock to be used (e.g. get its rate through clk_get_rate)
      it should be prepared and enabled first.

      Also, while the clock is enabled the driver must hold a reference to it,

      MIPS: Tidy up FPU context switching

      Rather than saving the scalar FP or vector context in the assembly
      resume function, reuse the existing C code we have in fpu.h to do
      exactly that. This reduces duplication, results in a much easier to read
      resume function & should allow the compiler to optimise out more MSA
      code due to is_msa_enabled()/cpu_has_msa being known-zero at compile
      time for kernels without MSA support.

      MIPS: Remove all the uses of custom gpio.h

      Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
      machines, and each machine type provides its own gpio.h. However
      only a handful really implement the GPIO API, most just forward
      everythings to gpiolib.

      The Alchemy machine is notable as it provides a system to allow
      implementing the GPIO API at the board level. But it is not used by
      any board currently supported, so it can also be removed.

      For most machine types we can just remove the custom gpio.h, as well
      as the custom wrappers if some exists. Some of the code found in
      the wrappers must be moved to the respective GPIO driver.

      A few more fixes are need in some drivers as they rely on linux/gpio.h
      to provides some machine specific definitions, or used asm/gpio.h
      instead of linux/gpio.h for the gpio API.

      MIPS: Add implementation of dma_map_ops.mmap()

      The generic implementation of dma_map_ops.mmap(), dma_common_mmap(),
      is not correct for non-coherent devices. It expects to be passed a
      virtual address previously returned by dma_alloc_coherent(), which for
      a non-coherent device will return a KSEG1 address. It then attempts to
      convert that virtual address to a physical address using virt_to_page()
      which will yield an incorrect address.

      Also, dma_common_mmap() does not handle the DMA_ATTR_WRITE_COMBINE
      attribute, and therefore dma_mmap_writecombine() will not actually set
      the appropriate pgprot_t flags for write combining.

      This patch adds an implementation of dma_map_ops.mmap() that correctly
      handles KSEG1 addresses, and enables write combining when requested.

      MIPS: AT_HWCAP aux vector infrastructure

      In order for userland to determine whether various features are safe to
      use, it will need to know both that the hardware supports those features
      and that the kernel is recent enough & configured appropriately to
      support them. For example under the O32 modeless FP proposal the dynamic
      linker & ifunc resolvers will need this information.  The kernel is the
      only thing in a position to know availability accurately, so the kernel
      needs to provide the information to userland. This patch introduces the
      infrastructure to provide the AT_HWCAP aux vector to userland in order
      to provide that information. It also defines the 2 currently specified
      flags, which indicate MIPSr6 & MSA support.

      MIPS: Save MSA extended context around signals

      It is desirable for signal handlers to be allowed to make use of MSA,
      particularly if auto vectorisation is used when compiling a program.
      The MSA context must therefore be saved & restored before & after
      invoking the signal handler. Make use of the extended context structs
      defined in the preceding patch to save MSA context after the sigframe
      when appropriate.

      MIPS: Add definitions for extended context

      The context introduced by MSA needs to be saved around signals. However,
      we can't increase the size of struct sigcontext because that will change
      the offset of the signal mask in struct sigframe or struct ucontext.
      This patch instead places the new context immediately after the struct
      sigframe for traditional signals, or similarly after struct ucontext for
      RT signals. The layout of struct sigframe & struct ucontext is identical
      from their sigcontext fields onwards, so the offset from the sigcontext
      to the extended context will always be the same regardless of the type
      of signal.

      Userland will be able to search through the extended context by using
      the magic values to detect which types of context are present. Any
      unrecognised context can be skipped over using the size field of struct
      extcontext. Once the magic value END_EXTCONTEXT_MAGIC is seen it is
      known that there are no further extended context structures to examine.

      This approach is somewhat similar to that taken by ARM to save VFP &
      other context at the end of struct ucontext.

      Userland can determine whether extended context is present by checking
      for the USED_EXTCONTEXT bit in the sc_used_math field of struct
      sigcontext. Whilst this could potentially change the historic semantics
      of sc_used_math if further extended context which does not imply FP
      context were to be introduced in the future, I have been unable to find
      any userland code making use of sc_used_math at all. Using one of the
      fields described as unused in struct sigcontext was considered, but the
      kernel does not already write to those fields so there would be no
      guarantee of the field being clear on older kernels. Other alternatives
      would be to have userland check the kernel version, or to have a HWCAP
      bit indicating presence of extended context. However there is a desire
      to have the context & information required to decode it be self
      contained such that, for example, debuggers could decode the saved
      context easily.

      MIPS: Indicate FP mode in sigcontext sc_used_math

      The sc_used_math field of struct sigcontext & its variants has
      traditionally been used as a boolean value indicating only whether or
      not floating point context is saved within the sigcontext. With various
      supported FP modes & the ability to switch between them this information
      will no longer be enough to decode the meaning of the data stored in the
      sc_fpregs fields of struct sigcontext.

      To make that possible 3 bits are defined within sc_used_math:

        - Bit 0 (USED_FP) represents whether FP was used, essentially
          providing the boolean flag which sc_used_math as a whole provided
          previously.

        - Bit 1 (USED_FR1) provides the value of the Status.FR bit at the time
          the FP context was saved.

        - Bit 2 (USED_HYBRID_FPRS) indicates whether the FP context was saved
          under the hybrid FPR scheme. Essentially, when set the odd singles
          are located in bits 63:32 of the preceding even indexed sc_fpregs
          element.

      Any userland that tests whether the sc_used_math field is zero or
      non-zero will continue to function as expected. Having said that, I
      could not find any userland which uses the sc_used_math field at all.

      MIPS: Skip odd double FP registers when copying FP32 sigcontext

      When a task uses 32 bit floating point, the odd indexed 32b register
      values are stored in bits 63:32 of the preceding even indexed 64b
      FP register field in saved context. Thus there is no point in
      preserving the odd indexed 64b register fields since they hold no
      valid context. This patch will cause them to be skipped, as is
      already done in arch/mips/kernel/signal32.c.

      MIPS: Refactor dumping of TLB registers for r3k/r4k

      The TLB registers are dumped in a couble of places:
       - sysrq_tlbdump_single() - when dumping TLB state.
       - do_mcheck() - in response to a machine check error.

      The main TLB registers also differ between r3k and r4k, but r4k appears
      to be assumed.

      Refactor this code into a dump_tlb_regs() function, implemented for both
      r3k and r4k, and used by both of the above functions.

      MIPS: Use unsigned int when reading CP0 registers

      Update __read_32bit_c0_register() and __read_32bit_c0_ctrl_register() to
      use "unsigned int res;" instead of "int res;". There is little reason to
      treat these register values as signed. They are either counters (which
      by definition are unsigned) or are made up of various bit fields to be
      interpreted as per the CPU datasheet.

      This has come up via u-boot[1] which sync's asm/mipsregs.h with the
      kernel. In u-boots case the value read from read_c0_count() is assigned
      to an unsigned long [2] which triggers a sign extension and causes a
      bug.

      U-boot should probably be more explicit about the types used for the
      timer_read_counter() API but that aside is there any reason to treat
      these values as signed integers? A quick grep around the arch/mips makes
      me thing that there may be some bugs lurking when read_c0_count() starts
      to yield a negative value but I haven't really explored any of them.

      MIPS: MSA unaligned memory access support

      The MSA architecture specification allows for hardware to not implement
      unaligned vector memory accesses in some or all cases. A typical example
      of this is the I6400 core which does not implement unaligned vector
      memory access when the memory crosses a page boundary. The architecture
      also requires that such memory accesses complete successfully as far as
      userland is concerned, so the kernel is required to emulate them.

      This patch implements support for emulating unaligned MSA ld & st
      instructions by copying between the user memory & the tasks FP context
      in struct thread_struct, updating hardware registers from there as
      appropriate in order to avoid saving & restoring the entire vector
      context for each unaligned memory access.

      Tested both using an I6400 CPU and with a QEMU build hacked to produce
      AdEL exceptions for unaligned vector memory accesses.

      [paul.burton@xxxxxxxxxx:
        - Remove #ifdef's
        - Move msa_op into enum major_op rather than #define
        - Replace msa_{to,from}_wd with {read,write}_msa_wr_{b,h,w,l} and the
          format-agnostic wrappers, removing the custom endian mangling for
          big endian systems.
        - Restructure the msa_op case in emulate_load_store_insn to share
          more code between the load & store cases.
        - Avoid the need for a temporary union fpureg on the stack by simply
          reusing the already suitably aligned context in struct
          thread_struct.
        - Use sizeof(*fpr) rather than hardcoding 16 as the size for user
          memory checks & copies.
        - Stop recalculating the address of the unaligned vector memory access
          and rely upon the value read from BadVAddr as we do for other
          unaligned memory access instructions.
        - Drop the now unused val8 & val16 fields in union fpureg.
        - Rewrite commit message.
        - General formatting cleanups.]

      MIPS: Remove "weak" from mips_cdmm_phys_base() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
      decl")).

      mips_cdmm_phys_base() is defined only in 
arch/mips/mti-malta/malta-memory.c
      so there's no problem with multiple definitions.  But it works better to
      have a weak default implementation and allow a strong function to override
      it.  Then we don't have to test whether a definition is present, and if
      there are ever multiple strong definitions, we get a link error instead of
      calling a random definition.

      Add a weak mips_cdmm_phys_base() definition and remove the weak annotation
      from the declaration in arch/mips/include/asm/cdmm.h.

      MIPS: Remove "weak" from get_c0_compare_int() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node

      get_c0_compare_int() is defined in several files.  Each definition is 
weak,
      so I assume Kconfig prevents two or more from being included.  The caller
      contains default code used when get_c0_compare_int() isn't defined at all.

      Add a weak get_c0_compare_int() definition with the default code and 
remove
      the weak annotation from the declaration.

      Then the platform implementations will be strong and will override the 
weak
      default.  If multiple platforms are ever configured in, we'll get a link
      error instead of calling a random platform's implementation.

      KVM: PPC: Book3S: Fix size of the PSPB register

      The size of the Problem State Priority Boost Register is only
      32 bits, but the kvm_vcpu_arch->pspb variable is declared as
      "ulong", ie. 64-bit. However, the assembler code accesses this
      variable with 32-bit accesses, and the KVM_REG_PPC_PSPB macro
      is defined with SIZE_U32, too, so that the current code is
      broken on big endian hosts: kvmppc_get_one_reg_hv() will only
      return zero for this register since it is using the wrong half
      of the pspb variable. Let's fix this problem by adjusting the
      size of the pspb field in the kvm_vcpu_arch structure.

      KVM: PPC: Book3S HV: Exit on H_DOORBELL if HOST_IPI is set

      The code that handles the case when we receive a H_DOORBELL interrupt
      has a comment which says "Hypervisor doorbell - exit only if host IPI
      flag set".  However, the current code does not actually check if the
      host IPI flag is set.  This is due to a comparison instruction that
      got missed.

      As a result, the current code performs the exit to host only
      if some sibling thread or a sibling sub-core is exiting to the
      host.  This implies that, an IPI sent to a sibling core in
      (subcores-per-core != 1) mode will be missed by the host unless the
      sibling core is on the exit path to the host.

      This patch adds the missing comparison operation which will ensure
      that when HOST_IPI flag is set, we unconditionally exit to the host.

      KVM: PPC: Book3S HV: Fix race in starting secondary threads

      The current dynamic micro-threading code has a race due to which a
      secondary thread naps when it is supposed to be running a vcpu. As a
      side effect of this, on a guest exit, the primary thread in
      kvmppc_wait_for_nap() finds that this secondary thread hasn't cleared
      its vcore pointer. This results in "CPU X seems to be stuck!"
      warnings.

      The race is possible since the primary thread on exiting the guests
      only waits for all the secondaries to clear its vcore pointer. It
      subsequently expects the secondary threads to enter nap while it
      unsplits the core. A secondary thread which hasn't yet entered the nap
      will loop in kvm_no_guest until its vcore pointer and the do_nap flag
      are unset. Once the core has been unsplit, a new vcpu thread can grab
      the core and set the do_nap flag *before* setting the vcore pointers
      of the secondary. As a result, the secondary thread will now enter nap
      via kvm_unsplit_nap instead of running the guest vcpu.

      Fix this by setting the do_nap flag after setting the vcore pointer in
      the PACA of the secondary in kvmppc_run_core. Also, ensure that a
      secondary thread doesn't nap in kvm_unsplit_nap when the vcore pointer
      in its PACA struct is set.

      Merge tag 'dm-4.3-changes' of 
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

      Pull device mapper update from Mike Snitzer:

       - a couple small cleanups in dm-cache, dm-verity, persistent-data's
         dm-btree, and DM core.

       - a 4.1-stable fix for dm-cache that fixes the leaking of deferred bio
         prison cells

       - a 4.2-stable fix that adds feature reporting for the dm-stats
         features added in 4.2

       - improve DM-snapshot to not invalidate the on-disk snapshot if
         snapshot device write overflow occurs; but a write overflow triggered
         through the origin device will still invalidate the snapshot.

       - optimize DM-thinp's async discard submission a bit now that late bio
         splitting has been included in block core.

       - switch DM-cache's SMQ policy lock from using a mutex to a spinlock;
         improves performance on very low latency devices (eg. NVMe SSD).

       - document DM RAID 4/5/6's discard support

      [ I did not pull the slab changes, which weren't appropriate for this
        tree, and weren't obviously the right thing to do anyway.  At the very
        least they need some discussion and explanation before getting merged.

      mtd: spi-nor: fix NULL dereference when no match found in spi_nor_ids[]

      Commit 06bb6f5a69df ("mtd: spi-nor: stop (ab)using struct
      spi_device_id") converted an array into a pointer, which means that
      we should be checking if the pointer goes anywhere, not whether the C
      string is empty. To do the latter means we dereference a NULL pointer
      when we reach the terminating entry, for which 'name' is now NULL
      instead of an array { 0, 0, ... }.

      Sample crash:

      netfilter: nf_conntrack: make nf_ct_zone_dflt built-in

      Fengguang reported, that some randconfig generated the following linker
      issue with nf_ct_zone_dflt object involved:

        [...]
        CC      init/version.o
        LD      init/built-in.o
        net/built-in.o: In function `ipv4_conntrack_defrag':
        nf_defrag_ipv4.c:(.text+0x93e95): undefined reference to

        nf_defrag_ipv6_hooks.c:(.text+0xe3ffe): undefined reference to 
`nf_ct_zone_dflt'
        make: *** [vmlinux] Error 1

      Given that configurations exist where we have a built-in part, which is
      accessing nf_ct_zone_dflt such as the two handlers nf_ct_defrag_user()
      and nf_ct6_defrag_user(), and a part that configures nf_conntrack as a
      module, we must move nf_ct_zone_dflt into a fixed, guaranteed built-in
      area when netfilter is configured in general.

      Therefore, split the more generic parts into a common header under
      include/linux/netfilter/ and move nf_ct_zone_dflt into the built-in
      section that already holds parts related to CONFIG_NF_CONNTRACK in the
      netfilter core. This fixes the issue on my side.

      net: fec: clear receive interrupts before processing a packet

      The patch just to re-submit the patch "db3421c114cfa6326" because the
      patch "4d494cdc92b3b9a0" remove the change.

      Clear any pending receive interrupt before we process a pending packet.
      This helps to avoid any spurious interrupts being raised after we have
      fully cleaned the receive ring, while still allowing an interrupt to be
      raised if we receive another packet.

      The position of this is critical: we must do this prior to reading the
      next packet status to avoid potentially dropping an interrupt when a
      packet is still pending.

      null_blk: fix wrong capacity when bs is not 512 bytes

      set_capacity() sets device's capacity using 512 bytes sectors.
      null_blk calculates the number of sectors by size / bs, which
      set_capacity is called with. This led to null_blk exposing the
      wrong number of sectors when bs is not 512 bytes.

      perf tools: Fix use of wrong event when processing exit events

      In a couple of cases the 'comm' member of 'union event' has been used
      instead of the correct member ('fork') when processing exit events.

      In the cases where it has been used incorrectly, only the 'pid' and
      'tid' are affected.  The 'pid' value would be correct anyway because it
      is in the same position in 'comm' and 'fork' events, but the 'tid' would
      have been incorrectly assigned from 'ppid'.

      However, for exit events, the kernel puts the current task in the 'ppid'
      and 'ttid' which is the same as the exiting task.  That is 'ppid' ==
      'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the
      data goes wrong only when tracing multi-threaded programs.

      It is hard to find an example of how this would produce an error in
      practice.  There are 3 occurences of the fix:

      1. perf script is only affected if !sample_id_all which only happens on
        old kernels.

      2. intel_pt is only affected when decoding without timestamps
         and would probably still decode correctly - the exit event is
         only used to flush out data which anyway gets flushed at the
         end of the session

      3. intel_bts also uses the exit event to flush data which
         would probably not cause errors as it would get flushed at
         the end of the session instead

      Pull core block updates from Jens Axboe:
       "This first core part of the block IO changes contains:

         - Cleanup of the bio IO error signaling from Christoph.  We used to
           rely on the uptodate bit and passing around of an error, now we
           store the error in the bio itself.

         - Improvement of the above from myself, by shrinking the bio size
           down again to fit in two cachelines on x86-64.

         - Revert of the max_hw_sectors cap removal from a revision again,
           from Jeff Moyer.  This caused performance regressions in various
           tests.  Reinstate the limit, bump it to a more reasonable size
           instead.

         - Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.
           Most devices have huge trim limits, which can cause nasty latencies
           when deleting files.  Enable the admin to configure the size down.
           We will look into having a more sane default instead of UINT_MAX
           sectors.

         - Improvement of the SGP gaps logic from Keith Busch.

         - Enable the block core to handle arbitrarily sized bios, which
           enables a nice simplification of bio_add_page() (which is an IO hot
           path).  From Kent.

         - Improvements to the partition io stats accounting, making it
           faster.  From Ming Lei.

         - Also from Ming Lei, a basic fixup for overflow of the sysfs pending
           file in blk-mq, as well as a fix for a blk-mq timeout race
           condition.

         - Ming Lin has been carrying Kents above mentioned patches forward
           for a while, and testing them.  Ming also did a few fixes around
           that.

         - Sasha Levin found and fixed a use-after-free problem introduced by
           the bio->bi_error changes from Christoph.

         - Small blk cgroup cleanup from Viresh Kumar"

      xen-netback: add support for multicast control

      Xen's PV network protocol includes messages to add/remove ethernet
      multicast addresses to/from a filter list in the backend. This allows
      the frontend to request the backend only forward multicast packets
      which are of interest thus preventing unnecessary noise on the shared
      ring.

      The canonical netif header in git://xenbits.xen.org/xen.git specifies
      the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal
      necessary changes have been pulled into include/xen/interface/io/netif.h.

      To prevent the frontend from extending the multicast filter list
      arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries.
      This limit is not specified by the protocol and so may change in future.
      If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD
      sent by the frontend will be failed with NETIF_RSP_ERROR.

      sock, diag: fix panic in sock_diag_put_filterinfo

      diag socket's sock_diag_put_filterinfo() dumps classic BPF programs
      upon request to user space (ss -0 -b). However, native eBPF programs
      attached to sockets (SO_ATTACH_BPF) cannot be dumped with this method:

      Their orig_prog is always NULL. However, sock_diag_put_filterinfo()
      unconditionally tries to access its filter length resp. wants to copy
      the filter insns from there. Internal cBPF to eBPF transformations
      attached to sockets don't have this issue, as orig_prog state is kept.

      It's currently only used by packet sockets. If we would want to add
      native eBPF support in the future, this needs to be done through
      a different attribute than PACKET_DIAG_FILTER to not confuse possible
      user space disassemblers that work on diag data.

      drm/exynos: remove buf_cnt from struct exynos_drm_fb

      Looking other drm drivers, there is no the restriction that framebuffer
      has only one buffer in .create_handle() callback. They use just first
      buffer.

      If this limitation is removed, there is no reason keeping buffer count
      for framebuffer, so we can remove buf_cnt from struct exynos_drm_fb.

      The correct check is to compute the position of the

      the delegation. While this does not completely eliminate the sending

      drm/i915: Always mark the object as dirty when used by the GPU

      There have been many hard to track down bugs whereby userspace forgot to
      flag a write buffer and then cause graphics corruption or a hung GPU
      when that buffer was later purged under memory pressure (as the buffer
      appeared clean, its pages would have been evicted rather than preserved
      and any changes more recent than in the backing storage would be lost).
      In retrospect this is a rare optimisation against memory pressure,
      already the slow path. If we always mark the buffer as dirty when
      accessed by the GPU, anything not used can still be evicted cheaply
      (ideal behaviour for mark-and-sweep eviction) but we do not run the risk
      of corruption. For correct read serialisation, userspace still has to
      notify when the GPU writes to an object. However, there are certain
      situations under which userspace may wish to tell white lies to the

      drm/dp: Add dp_aux_i2c_speed_khz module param to set the assume i2c bus 
speed

      To help with debugging i2c-over-aux issues, add a module parameter than
      can be used to tweak the assumed i2c bus speed, and thus the maximum
      number of retries we will do for each aux message.

      drm/dp: Adjust i2c-over-aux retry count based on message size and i2c bus 
speed

      Calculate the number of retries we should do for each i2c-over-aux
      message based on the time it takes to perform the i2c transfer vs. the
      aux transfer. We assume the shortest possible length for the aux
      transfer, and the longest possible (exluding clock stretching) for the
      i2c transfer.

      The DP spec has some examples on how to calculate this, but we don't
      calculate things quite the same way. The spec doesn't account for the
      retry interval (assumes immediate retry on defer), and doesn't assume
      the best/worst case behaviour as we do.

      Note that currently we assume 10 kHz speed for the i2c bus. Some real
      world devices (eg. some Apple DP->VGA dongle) fails with less than 16
      retries. and that would correspond to something close to 15 kHz (with
      our method of calculating things) But let's just go for 10 kHz to be
      on the safe side. Ideally we should query/set the i2c bus speed via
      DPCD but for now this should at leaast remove the regression from the
      1->16 byte trasnfer size change. And of course if the sink completes
      the transfer quicker this shouldn't slow things down since we don't
      change the interval between retries.

      I did a few experiments with a DP->DVI dongle I have that allows you
      to change the i2c bus speed. Here are the results of me changing the
      actual bus speed and the assumed bus speed and seeing when we start
      to fail the operation:

      actual i2c khz          assumed i2c khz         max retries
      1                       1 ok -> 2 fail          211 ok -> 106 fail
      5                       8 ok -> 9 fail          27 ok -> 24 fail
      10                      17 ok -> 18 fail        13 ok -> 12 fail
      100                     210 ok -> 211 fail      2 ok -> 1 fail

      So based on that we have a fairly decent safety margin baked into
      the formula to calculate the max number of retries.

      drm/dp: Define AUX_RETRY_INTERVAL as 500 us

      Currently we react to native and i2c defers by waiting either 400-500 us
      or 500-600 us, depending on which code path we take. Consolidate them
      all to one define AUX_RETRY_INTERVAL which defines the minimum interval.
      Since we've been using two different intervals pick the longer of them
      and define AUX_RETRY_INTERVAL as 500 us. For the maximum just use
      AUX_RETRY_INTERVAL+100 us.

      I want to have a define for this so that I can use it when calculating
      the estimated duration of i2c-over-aux transfers. Without a define it
      would be very easy to change the sleep duration and neglect to update
      the i2c-over-aux estimates.

      spi: spi-pxa2xx: Check status register to determine if SSSR_TINT is

      On Intel Baytrail, there is case when interrupt handler get called, no SPI
      message is captured. The RX FIFO is indeed empty when RX timeout pending
      interrupt (SSSR_TINT) happens.

      Use the BIOS version where both HSUART and SPI are on the same IRQ. Both
      drivers are using IRQF_SHARED when calling the request_irq function. When
      running two separate and independent SPI and HSUART application that
      generate data traffic on both components, user will see messages like
      below on the console:

      This commit will fix this by first checking Receiver Time-out Interrupt,
      if it is disabled, ignore the request and return without servicing.

      x86/mm/srat: Print non-volatile flag in SRAT

      With the addition of NVDIMM support, a question came up as to
      whether NVDIMM ranges should be in the SRAT with this bit set.
      I think the consensus was no because the ranges are in the NFIT
      with proximity domain information there.

      ACPI is not clear on the meaning of this bit in the SRAT.
      If someone is setting it, we might want to ask them what they
      expect to happen with it.

      Right now this bit is only printed if all the ACPI debug
      information is turned on.

      Intel Wired LAN Driver Updates 2015-09-01

      This series contains updates to i40e, ixgbe and ixgbevf.

      Anjali fixes a bug in i40e where the port is not receiving multicast or 
VLAN
      tagged packets in promiscuous mode.  Which can occur when a software 
bridge
      is created on top of the device.

      Don adds support in ixgbe that indicates the presence of management 
firmware.
      Added support for entering low power link up state on devices that support
      it when the device is closing or suspending.  Updated the driver to report
      unknown bus speed and width since IOSF does not report a PCIe bus speed or
      width for X550 devices.  Also added the new bus type for integrated I/O
      interface (IOSF).  Cleaned up of redundant code in ixgbe.

      Mark adds support for UDP-encapsulation transmit checksum and for VXLAN
      receive offloads.  Introduces a helper function to do the register access
      and processing to avoid needless PHY access on copper PHYs.  Added support
      for reporting 2.5G link speed.  Fixed warnings resulting from redundant
      initializations of the get_bus_info field.

      Maninder Singh updates the ixgbe driver to use kzalloc instead of kcalloc
      for allocation of one thing.

      Tom Barbette adds support for ethtool to change the rxfh indirection table
      and/or key using ethtool interface.

      Emil resolves an issue where users were not able to dynamically set number
      of queues for 82598 via ethtool -L.

      Alex Williamson removes bimodal SR-IOV disabling behavior since it is
      confusing to users and results in a state where the PF is broken for other
      uses unless the user sets sriov_numvfs to zero prior to unbinding the
      device.

        We have a few updates of the generic power domains framework and a
        reorganization of the ACPI device enumeration code and bus type
        operations.

        And a lot of fixes and cleanups all over.

        Included is one branch from the MFD tree as it contains some
        PM-related driver core and ACPI PM changes a few other commits are
        based on.

        Specifics:

         - ACPICA update to upstream revision 20150818 including method
           tracing extensions to allow more in-depth AML debugging in the
           kernel and a number of assorted fixes and cleanups (Bob Moore, Lv
           Zheng, Markus Elfring).

         - ACPI sysfs code updates and a documentation update related to AML
           method tracing (Lv Zheng).

         - ACPI EC driver fix related to serialized evaluations of _Qxx
           methods and ACPI tools updates allowing the EC userspace tool to be
           built from the kernel source (Lv Zheng).

         - ACPI processor driver updates preparing it for future introduction
           of CPPC support and ACPI PCC mailbox driver updates (Ashwin
           Chaugule).

         - ACPI interrupts enumeration fix for a regression related to the
           handling of IRQ attribute conflicts between MADT and the ACPI
           namespace (Jiang Liu).

         - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi
           Kasagar).

         - ACPI device registration code reorganization to separate the
           sysfs-related code and bus type operations from the rest (Rafael J
           Wysocki).

         - Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause,
           Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss).

         - ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan
           Xinhui, Rafael J Wysocki).

         - cpufreq core cleanups on top of the previous changes allowing it to
           preseve its sysfs directories over system suspend/resume (Viresh
           Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior).

         - cpufreq fixes and cleanups related to governors (Viresh Kumar).

         - cpufreq updates (core and the cpufreq-dt driver) related to the
           turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz).

         - New DT bindings for Operating Performance Points (OPP), support for
           them in the OPP framework and in the cpufreq-dt driver plus related
           OPP framework fixes and cleanups (Viresh Kumar).

         - cpufreq powernv driver updates (Shilpasri G Bhat).

         - New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen).

         - Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups
           and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean).

         - intel_pstate driver updates including Skylake-S support, support
           for enabling HW P-states per CPU and an additional vendor bypass
           list entry (Kristen Carlson Accardi, Chen Yu, Ethan Zhao).

         - cpuidle core fixes related to the handling of coupled idle states
           (Xunlei Pang).

         - intel_idle driver updates including Skylake Client support and
           support for freeze-mode-specific idle states (Len Brown).

         - Driver core updates related to power management (Andy Shevchenko,
           Rafael J Wysocki).

         - Generic power domains framework fixes and cleanups (Jon Hunter,
           Geert Uytterhoeven, Rajendra Nayak, Ulf Hansson).

         - Device PM QoS framework update to allow the latency tolerance
           setting to be exposed to user space via sysfs (Mika Westerberg).

         - devfreq support for PPMUv2 in Exynos5433 and a fix for an incorrect
           exynos-ppmu DT binding (Chanwoo Choi, Javier Martinez Canillas).

         - System sleep support updates (Alan Stern, Len Brown, SungEun Kim).

         - rockchip-io AVS support updates (Heiko Stuebner).

         - PM core clocks support fixup (Colin Ian King).

         - Power capping RAPL driver update including support for Skylake H/S
           and Broadwell-H (Radivoje Jovanovic, Seiichi Ikarashi).

         - Generic device properties framework fixes related to the handling
           of static (driver-provided) property sets (Andy Shevchenko).

         - turbostat and cpupower updates (Len Brown, Shilpasri G Bhat,
           Shreyas B Prabhu)"

      ixgbe: Remove bimodal SR-IOV disabling

      When unbinding an SR-IOV device with VFs configured from ixgbe, the
      driver behaves in one of two ways.  If max_vfs was specified, the
      SR-IOV state is disabled, removing the VFs.  The occurs regardless of
      whether the VF count was later modified through sysfs.  If however
      max_vfs is zero, such as by not specifying the module parameter, the
      VFs persist after the PF is unbound from ixgbe.  If the PF is then
      bound to vfio-pci to be assigned to a VM, the PF is non-functional.

      >From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV
      sysfs callback operation") clearly intended this alternate behavior,
      but probably didn't realize the PF doesn't work in this mode.

      This bimodal behavior is confusing to users and results in a state
      where the PF is broken for other uses unless the user sets
      sriov_numvfs to zero prior to unbinding the device.  Remove this
      behavior so that VFs are removed and the PF is functional for other
      uses after unbind, regardless of the way VFs are enabled.

      ixgbe: Remove second instance of lan_id variable

      This patch removes the redundant lan_id in the phy struct and uses
      the bus version.  Both variables exist and intend to represent the
      STATUS register LAN_ID field.  However, phy.lan_id is not bit shifted
      so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1.
      Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and
      bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional
      lan_id variable and this should make the code less confusing.

      i40e: Set defport behavior for the Main VSI when in promiscuous mode

      This fixes bugs where the port is not receiving multicast or VLAN tagged
      packets when in promiscuous mode. This can occur when a SW bridge is
      created on top of the device.

      This also fixes issues where the promiscuous behavior setting was not
      being preserved across a reset caused by features being enabled or
      disabled.

      We are using defport instead of doing a true promiscuous mode because we 
do
      not need to receive the SRIOV or VMDq VSI directed traffic which would 
suck
      up bandwidth and is really not intended for the SW bridge.

      In addition, with defport we get VLAN promiscuous behavior which is not
      possible from the VSI level promiscuous setting.

       "This finishes up the changes to ensure proc and sysfs do not start
        implementing executable files, as the there are application today that
        are only secure because such files do not exist.

        It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that
        did not show the proper source for files bind mounted from
        /proc/<pid>/ns/*.

        It also straightens out the handling of clone flags related to user
        namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER)
        when files such as /proc/<pid>/environ are read while <pid> is calling
        unshare.  This winds up fixing a minor bug in unshare flag handling
        that dates back to the first version of unshare in the kernel.

        Finally, this fixes a minor regression caused by the introduction of
        sysfs_create_mount_point, which broke someone's in house application,
        by restoring the size of /sys/fs/cgroup to 0 bytes.  Apparently that
        application uses the directory size to determine if a tmpfs is mounted
        on /sys/fs/cgroup.

        The bind mount escape fixes are present in Al Viros for-next branch.

      ====================
      flow_dissector: Paramterize dissection and other features

      This patch set adds some new capabilities to flow_dissector:

      - Add flags to flow dissector functions to control dissection
        - Flag to stop dissection when L3 header is seen (don't
          dissect L4)
        - Flag to stop dissection when encapsulation is detected
        - Flag to parse first fragment of fragmented packet. This
          may provide L4 ports
      - Added new reporting in key_control
        - Packet is a fragment
        - Packet is a first fragment
        - Packet has encapsulation

      Also:
        - Make __skb_set_sw_hash a general function
        - Create functions to get a flow hash based on flowi4 or flowi6
          structures without an reference to an skbuff
        - Ignore flow dissector return value from ___skb_get_hash. Just
          use whatever key fields are found to make a hash

      Tested:

      Ran 200 netperf TCP_RR instances for IPv6 and IPv4. Did not see any
      regression. Ran UDP_RR with 10000 byte request and response size
      for IPv4 and IPv6, no regression observed however I did see better
      performance with IPv6 flow labels due to use of flow labels for L4
      hash.

      flow_dissector: Ignore flow dissector return value from ___skb_get_hash

      In ___skb_get_hash ignore return value from skb_flow_dissect_flow_keys.
      A failure in that function likely means that there was a parse error,
      so we may as well use whatever fields were found before the error was
      hit.  This is also good because it means we won't keep trying to derive
      the hash on subsequent calls to skb_get_hash for the same packet.

      flow_dissector: Add flag to stop parsing when an IPv6 flow label is seen

      Add an input flag to flow dissector on rather dissection should be
      stopped when a flow label is encountered. Presumably, the flow label
      is derived from a sufficient hash of an inner transport packet so
      further dissection is not needed (that is ports are not included in
      the flow hash). Using the flow label instead of ports has the additional
      benefit that packet fragments should hash to same value as non-fragments
      for a flow (assuming that the same flow label is used).

      We set this flag by default in for skb_get_hash.

      Instead of returning immediately (on a parsing failure for instance) we
      jump to cleanup code. This always sets protocol values in key_control
      (even on a failure there is still valid information in the key_tags that
      was set before the problem was hit).

      flowi: Abstract out functions to get flow hash based on flowi

      Create __get_hash_from_flowi6 and __get_hash_from_flowi4 to get the
      flow keys and hash based on flowi structures. These are called by
      __skb_get_hash_flowi6 and __skb_get_hash_flowi4. Also, created
      get_hash_from_flowi6 and get_hash_from_flowi4 which can be called
      when just the hash value for a flowi is needed.

      skbuff: Make __skb_set_sw_hash a general function

      Move __skb_set_sw_hash to skbuff.h and add __skb_set_hash which is
      a common method (between __skb_set_sw_hash and skb_set_hash) to set
      the hash in an skbuff.

      tg3: Fix temperature reporting

      The temperature registers appear to report values in degrees Celsius

      The problem is that mdiobus_unregister() deletes the bus device before
      unregistering the phy devices on the bus. This wasn't a problem before
      because the phys were not children of the bus:

        /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03
        /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0

      But now that they are:

        
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03

      when mdiobus_unregister deletes the bus device, the phy subdirs are
      removed from sysfs also. So when the phys are unregistered afterward,
      we get the warning. This patch changes the order so that phys are
      unregistered before the bus device is deleted.

the bus' parent.")

        For those of you feeling less adventurous, added hardware support on

        We've got something for everyone here!

      Pull ARM SoC driver updates from Olof Johansson:
       "Some releases this branch is nearly empty, others we have more stuff.
        It tends to gather drivers that need SoC modification or dependencies
        such that they have to (also) go in through our tree.

        For this release, we have merged in part of the reset controller tree
        (with handshake that the parts we have merged in will remain stable),
        as well as dependencies on a few clock branches.

        In general, new items here are:

         - Qualcomm driver for SMM/SMD, which is how they communicate with the
           coprocessors on (some) of their platforms

         - memory controller work for ARM's PL172 memory controller

         - reset drivers for various platforms

         - PMU power domain support for Marvell platforms

         - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller
           per-SoC support"

      NFSv4.1/flexfiles: Fix freeing of mirrors

      Mirrors are now shared objects, so we should not be freeing them directly
      inside ff_layout_free_lseg(). We should already be doing the right thing
      in _ff_layout_free_lseg(), so just let it handle things.

      Also ensure that ff_layout_free_mirror() frees the RPC credential if it
      is set.

        the plat-samsung directory is cleaned out by moving most of the
        previously shared-location-but-not-actually-shared files from there to

        There are other sets of changes in here as well:

         - Rob Herring removed use of set_irq_flags under all platforms and
           moved to genirq alternatives

      nfsd: return CLID_INUSE for unexpected SETCLIENTID_CONFIRM case

      Somebody with a Solaris client was hitting this case.  We haven't
      figured out why yet, and don't have a reproducer.  Meanwhile Frank
      noticed that RFC 7530 actually recommends CLID_INUSE for this case.
      Unlikely to help the original reporter, but may as well fix it.

      irqchip/GIC: Fix EOImode setting for non-DT/ACPI systems

      Non-DT/ACPI systems call directly into the GIC driver at init time.
      Turns out 0b996fd35957 ("irqchip/GIC: Convert to EOImode == 1")
      breaks old non firmware-driven platforms, as the driver only
      works out the capability of the platform on the DT/ACPI paths.

      Fix this thinko by forcing EOImode==0 on non-DT platforms,
      which are not capable of supporting a hypervisor anyway.

      perf tools: Fix link time error with sample_reg_masks on non x86

      This patch makes perf compile on non x86 platforms by defining a weak
      symbol for sample_reg_masks[] in util/perf_regs.c.

      The patch also moves the REG() and REG_END() macros into the
      util/per_regs.h header file. The macros are renamed to
      SMPL_REG/SMPL_REG_END to avoid clashes with other header files.

      This patch fixes it by adding $(call rule_mkdir) like other similar rules.

      perf dwarf: Fix potential array out of bounds access

      There is a problem in the dwarf-regs.c files for sh, sparc and x86 where
      it is possible to make an out-of-bounds array access when searching for
      register names.

      This patch fixes it by replacing '<=' to '<', so when register (number
      == XXX_MAX_REGS), get_arch_regstr() will return NULL.

      cpufreq: update user_policy.* on success

      'user_policy' caches properties of a policy that are set by userspace.
      And these must be updated only if cpufreq core was successful in
      updating them based on request from user space.

      In store_scaling_governor(), we are updating user_policy.policy and
      user_policy.governor even if cpufreq_set_policy() failed. That's
      incorrect.

      Fix this by updating user_policy.* only if we were successful in
      updating the properties.

      cpufreq: mediatek: Add MT8173 cpufreq driver

      Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and
      2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage
      inputs, Vproc and Vsram are supplied by two regulators. For the big
      cluster, two regulators come from different PMICs. In this case, when
      scaling voltage inputs of the cluster, the voltages of two regulator
      inputs need to be controlled by software explicitly under the SoC
      specific limitation:

        100mV < Vsram - Vproc < 200mV

      which is called 'voltage tracking' mechanism. And when scaling the
      frequency of cluster clock input, the input MUX need to be parented to
      another "intermediate" stable PLL first and reparented to the original
      PLL once the original PLL is stable at the target frequency. This patch
      implements those mechanisms to enable CPU DVFS support for Mediatek
      MT8173 SoC.

      netfilter: conntrack: use nf_ct_tmpl_free in CT/synproxy error paths

      Commit 0838aa7fcfcd ("netfilter: fix netns dependencies with conntrack
      templates") migrated templates to the new allocator api, but forgot to
      update error paths for them in CT and synproxy to use nf_ct_tmpl_free()
      instead of nf_conntrack_free().

      Due to that, memory is being freed into the wrong kmemcache, but also
      we drop the per net reference count of ct objects causing an imbalance.

      In Brad's case, this leads to a wrap-around of net->ct.count and thus
      lets __nf_conntrack_alloc() refuse to create a new ct object:

        [   10.340913] xt_addrtype: ipv6 does not support BROADCAST matching
        [   10.810168] nf_conntrack: table full, dropping packet
        [   11.917416] r8169 0000:07:00.0 eth0: link up
        [   11.917438] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
        [   12.815902] nf_conntrack: table full, dropping packet
        [   15.688561] nf_conntrack: table full, dropping packet
        [   15.689365] nf_conntrack: table full, dropping packet
        [   15.690169] nf_conntrack: table full, dropping packet
        [   15.690967] nf_conntrack: table full, dropping packet
        [...]

      With slab debugging, it also reports the wrong kmemcache (kmalloc-512 vs.
      nf_conntrack_ffffffff81ce75c0) and reports poison overwrites, etc. Thus,
      to fix the problem, export and use nf_ct_tmpl_free() instead.

      i915: Set ddi_pll_sel in DP MST path

      The DP MST encoder config function never sets ddi_pll_sel, even though
      its value is programmed in its ->pre_enable() hook. That used to work
      because a new pipe_config was kzalloc'ed at every modeset, and the value
      of zero selects the highest clock for the PLL. Starting with the commit
      below, the value of ddi_pll_sel is preserved through modesets, and since
      the correct value wasn't properly setup by the MST code, it could lead
      to warnings and blank screens.

      drm/i915: Preserve SSC earlier

      Commit 92122789b2d6 ("drm/i915: preserve SSC if previously set v3")
      added code to intel_modeset_gem_init to override the SSC status read
      from VBT with the SSC status set by BIOS.

      However, intel_modeset_gem_init is invoked *after* intel_modeset_init,
      which calls intel_setup_outputs, which *modifies* SSC status by way of
      intel_init_pch_refclk. So unlike advertised, intel_modeset_gem_init
      doesn't preserve the SSC status set by BIOS but whatever
      intel_init_pch_refclk decided on.

      This is a problem on dual gpu laptops such as the MacBook Pro which
      require either a handler to switch DDC lines, or the discrete gpu
      to proxy DDC/AUX communication: Both the handler and the discrete
      gpu may initialize after the i915 driver, and consequently, an LVDS
      connector may initially seem disconnected and the SSC therefore
      is disabled by intel_init_pch_refclk, but on reprobe the connector
      may turn out to be connected and the SSC must then be enabled.

      Due to 92122789b2d6 however, the SSC is not enabled on reprobe since
      it is assumed BIOS disabled it while in fact it was disabled by
      intel_init_pch_refclk.

      Also, because the SSC status is preserved so late, the preserved value
      only ever gets used on resume but not on panel initialization:
      intel_modeset_init calls intel_init_display which indirectly calls
      intel_panel_use_ssc via multiple subroutines, *before* the BIOS value
      overrides the VBT value in intel_modeset_gem_init (intel_panel_use_ssc
      is the sole user of dev_priv->vbt.lvds_use_ssc).

      Fix this by moving the code introduced by 92122789b2d6 from
      intel_modeset_gem_init to intel_modeset_init before the invocation
      of intel_setup_outputs and intel_init_display.

      Add a DRM_DEBUG_KMS as suggested way back by Jani:

           nohz internals.  Now nohz integrates well full and idle and such
           hack have become needless.

         - Restart nohz full tick from irq exit.  (A simplification and a
           preparation for future optimization on scheduler kick to nohz

        and the performance testing results are encouraging.  Nevertheless we
        need to keep an eye on potential regressions, since this potentially
        affects every SMP workload in existence.

             * Add missing 'clockid' entries.

         - Introduce 'srcfile' sort key: (Andi Kleen)

             # perf record -F 10000 usleep 1
             # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
             <SNIP>

                26.49%  copy_page_64.S
                 5.49%  signal.c
                 0.51%  msr.h
             #

           It can be combined with other fields, for instance, experiment with
           '-s srcfile,symbol'.

           There are some oddities in some distros and with some specific
           DSOs, being investigated, so your mileage may vary.

         - Support per-event 'freq' term: (Namhyung Kim)

             $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 
sleep 1
             $ perf evlist -F
             cpu/instructions,freq=1234/: sample_freq=1234
             cycles: sample_period=1000
             $

         - Deref sys_enter pointer args with contents from probe:vfs_getname,
           showing pathnames instead of pointers in many syscalls in 'perf
           trace'.  (Arnaldo Carvalho de Melo)

         - Stop collecting /proc/kallsyms in perf.data files, saving about
           4.5MB on a typical x86-64 system, use the the symbol resolution
           routines used in all the other tools (report, top, etc) now that we
           can ask libtraceevent to use perf's symbol resolution code.
           (Arnaldo Carvalho de Melo)

         - Allow filtering out of perf's PID via 'perf record --exclude-perf'.
           (Wang Nan)

         - 'perf trace' now supports syscall groups, like strace, i.e:

             $ trace -e file touch file

           Will expand 'file' into multiple, file related, syscalls.  More
           work needed to add extra groups for other syscall groups, and also
           to complement what was added for the 'file' group, included as a
           proof of concept.  (Arnaldo Carvalho de Melo)

         - Add lock_pi stresser to 'perf bench futex', to test the kernel code
           related to FUTEX_(UN)LOCK_PI.  (Davidlohr Bueso)

         - Let user have timestamps with per-thread recording in 'perf record'
           (Adrian Hunter)

         - ... and tons of other changes, see the shortlog and the Git log for
           details"

       "The biggest changes in the core this time around have been some

        model list maintained for the class devices for regulators which will
        make the code smaller and avoid some potential bugs.

        highlights include:

         - a new API for setting voltages based on a minimum, target, maximum
           triplet

         - support for continuous voltage ranges rather than tables of
           explicit steps in the PWM regulator, requiring less explicit
           configuration

      ipv6: send NEWLINK on RA managed/otherconf changes

      The kernel is applying the RA managed/otherconf flags silently and
      forgets to send ifinfo notify to inform about their change when the
      router provides a zero reachable_time and retrans_timer as dnsmasq
      and many routers send it, which just means unspecified by this router
      and the host should continue using whatever value it is already using.
      Userspace may monitor the ifinfo notifications to activate dhcpv6.

      ====================
      DSA port configuration and status

      This patchset allows various switch port settings to be configured and
      port status to be sampled. Some of these patches have been posted
      before.

      The first three patches provide infrastructure for configuring a
      switch ports link speed and duplex from a fixed_link phy.

      Patch four then uses this infrastructure to allow the CPU and DSA
      ports of a switch to be configured using a fixed-link property in the
      device tree.

      Patches five and six allow a phy-mode property to be specified in the
      device tree, and allow this to be used for configuring RGMII delays.

      Patches seven through nine allow link status, for example that of an
      SFP module, to be read from a gpio.

      Changes since v1:

      Rewrite 9/9 so that it hopefully does not regression on

      net: phy: fixed_phy: Set phy capabilities even when link down.

      What features a phy supports is masked in genphy_config_init() by
      looking at the PHYs BMSR register.

      If the link is down, fixed_phy_update_regs() will only set the auto-
      negotiation capable bit in BMSR. Thus genphy_config_init() comes to
      the conclusion the PHY can only perform 10/Half, and masks out the
      higher speed features. If however the link it up, BMSR is set to
      indicate the speed the PHY is capable of auto-negotiating, and
      genphy_config_init() does not mask out the high speed features.

      To fix this, when the link is down, have fixed_phy_update_regs() leave
      the link status, auto-negotiation complete, and link partner
      capabilities unset, but set all the local capabilities depending on
      the fixed phy speed.

      net: phy: Allow PHY devices to identify themselves as Ethernet switches, 
etc.

      Some Ethernet MAC drivers using the PHY library require the hardcoding
      of link parameters when interfaced to a switch device, SFP module,
      switch to switch port, etc. This has typically lead to various ad-hoc
      implementations looking like this:

      - using a "fixed PHY" emulated device, which will provide link
        indication towards the Ethernet MAC driver and hardware

      - pretend there is no PHY and hardcode link parameters, ala mv643x_eth

      Based on that, it is desireable to have the PHY drivers advertise the
      correct link parameters, just like regular Ethernet PHYs towards their
      CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able
      to tell whether this link should be monitored or not. In the context
      of an Ethernet switch, SFP module, switch to switch link, we do not
      need to monitor this link since it should be always up.

      perf record: Add ability to name registers to record

      This patch modifies the -I/--int-regs option to enablepassing the name
      of the registers to sample on interrupt. Registers can be specified by
      their symbolic names. For instance on x86, --intr-regs=ax,si.

      The motivation is to reduce the size of the perf.data file and the
      overhead of sampling by only collecting the registers useful to a
      specific analysis. For instance, for value profiling, sampling only the
      registers used to passed arguements to functions.

      With no parameter, the --intr-regs still records all possible registers
      based on the architecture.

      To name registers, it is necessary to use the long form of the option,
      i.e., --intr-regs:

        $ perf record --intr-regs=si,di,r8,r9 .....

      To record any possible registers:

        $ perf record -I .....
        $ perf report --intr-regs ...

      To display the register, one can use perf report -D

      To list the available registers:

        $ perf record --intr-regs=\?
        available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10 
R11 R12 R13 R14 R15

      perf script: Enable printing of interrupted machine state

      This patch adds the output of the interrupted machine state (iregs) to
      perf script. It presents them  as NAME:VALUE so this is easy to parse
      during post processing.

      To capture the interrupted machine state:
         $ perf record -I ....

      to display iregs, use the -F option:

         $ perf script -F ip,iregs

      nfsd: ensure that delegation stateid hash references are only put once

      It's possible that a DELEGRETURN could race with (e.g.) client expiry,
      in which case we could end up putting the delegation hash reference more
      than once.

      Have unhash_delegation_locked return a bool that indicates whether it
      was already unhashed. In the case of destroy_delegation we only
      conditionally put the hash reference if that returns true.

      The other callers of unhash_delegation_locked call it while walking
      list_heads that shouldn't yet be detached. If we find that it doesn't
      return true in those cases, then throw a WARN_ON as that indicates that
      we have a partially hashed delegation, and that something is likely very
      wrong.

      nfsd: ensure that the ol stateid hash reference is only put once

      When an open or lock stateid is hashed, we take an extra reference to
      it. When we unhash it, we drop that reference. The code however does
      not properly account for the case where we have two callers concurrently
      trying to unhash the stateid. This can lead to list corruption and the
      hash reference being put more than once.

      Fix this by having unhash_ol_stateid use list_del_init on the st_perfile
      list_head, and then testing to see if that list_head is empty before
      releasing the hash reference. This means that some of the unhashing
      wrappers now become bool return functions so we can test to see whether
      the stateid was unhashed before we put the reference.

      Actually TP_printk() should never dereference an address saved in the ring
      buffer that points somewhere in the kernel. There's no guarantee that that
      object still exists (with the exception of static strings).

      Therefore change all the arguments for TP_printk(), so that it references
      values existing in the ring buffer only.

      While doing that, also fix another possible bug when argument xprt could 
be
      NULL and TP_fast_assign() tries to access it's elements.

      nfsd: allow more than one laundry job to run at a time

      We can potentially have several nfs4_laundromat jobs running if there
      are multiple namespaces running nfsd on the box. Those are effectively
      separated from one another though, so I don't see any reason to

      Also, create_singlethread_workqueue automatically adds the

      involved in any reclaim paths. I see no need for a rescuer thread.

      nfsd: don't WARN/backtrace for invalid container deployment.

      These messages, combined with the backtrace they trigger, makes it seem
      like a serious problem, though a quick search shows distros marking
      it as a "won't fix" non-issue when the problem is reported by users.

      The backtrace is overkill, and only really manages to show that if
      you follow the code path, you can't really avoid it with bootargs
      or configuration settings in the container.

      Given that, lets tone it down a bit and get rid of the WARN severity,
      and the associated backtrace, so people aren't needlessly alarmed.

      Also, lets drop the split printk line, since they are grep unfriendly.

      bpf tools: New API to get name from a BPF object

      Before this patch there's no way to connect a loaded bpf object
      to its source file. However, during applying perf's '--filter' to BPF
      object, without this connection makes things harder, because perf loads
      all programs together, but '--filter' setting is for each object.

      The API of bpf_object__open_buffer() is changed to allow passing a name.
      Fortunately, at this time there's only one user of it (perf test LLVM),
      so we change it together.

      ====================
      tcp: receive-side per route dctcp handling

      Original cover letter:

        Currently, the following case doesn't use DCTCP, even if it should:

          - responder has f.e. cubic as system wide default
          - 'ip route congctl dctcp $src' was set

        Then, DCTCP is NOT used if a DCTCP sender attempts to connect from a
        host in the $src range: ECT(0) is set, but listen_sk is not dctcp, so
        we fail the INET_ECN_is_not_ect sanity check.

        We also have to examine the dst used for the SYN/ACK reply to make
        this case work.

        In order to minimize additional cost, store the 'ecn is must have'
        information is the dst_features field.

        The set targets -next instead of -net since this doesn't seem to be a
        serious bug and to give the change more soak time until it hits linus
        tree.

      v1 -> v2:
       - Addressed Dave's feedback, not exposing any bits to user space
       - Added patch 3 to reject incorrect configurations

      tcp: use dctcp if enabled on the route to the initiator

      Currently, the following case doesn't use DCTCP, even if it should:
      A responder has f.e. Cubic as system wide default, but for a specific
      route to the initiating host, DCTCP is being set in RTAX_CC_ALGO. The
      initiating host then uses DCTCP as congestion control, but since the
      initiator sets ECT(0), tcp_ecn_create_request() doesn't set ecn_ok,
      and we have to fall back to Reno after 3WHS completes.

      We were thinking on how to solve this in a minimal, non-intrusive
      way without bloating tcp_ecn_create_request() needlessly: lets cache
      the CA ecn option flag in RTAX_FEATURES. In other words, when ECT(0)
      is set on the SYN packet, set ecn_ok=1 iff route RTAX_FEATURES
      contains the unexposed (internal-only) DST_FEATURE_ECN_CA. This allows
      to only do a single metric feature lookup inside tcp_ecn_create_request().

      ip-tunnel: Use API to access tunnel metadata options.

      Currently tun-info options pointer is used in few cases to
      pass options around. But tunnel options can be accessed using
      ip_tunnel_info_opts() API without using the pointer. Following
      patch removes the redundant pointer and consistently make use
      of API.

      dm cache: fix leaking of deferred bio prison cells

      There were two cases where dm_cell_visit_release() was being called,
      which removes the cell from the prison's rbtree, but the callers didn't
      also return the cell to the mempool.  Fix this by having them call
      free_prison_cell().

      This leak manifested as the 'kmalloc-96' slab growing until OOM.

      It is theoretically possible to process perf.data files created on x86
      and that contain Intel PT or Intel BTS data, on any other architecture,

      btrfs: async_thread: Fix workqueue 'max_active' value when initializing

      At initializing time, for threshold-able workqueue, it's max_active
      of kernel workqueue should be 1 and grow if it hits threshold.

      But due to the bad naming, there is both 'max_active' for kernel
      workqueue and btrfs workqueue.
      So wrong value is given at workqueue initialization.

      This patch fixes it, and to avoid further misunderstanding, change the
      member name of btrfs_workqueue to 'current_active' and 'limit_active'.

      Also corresponding comment is added for readability.

      btrfs: Add raid56 support for updating
       num_tolerated_disk_barrier_failures in btrfs_balance

      Code for updating fs_info->num_tolerated_disk_barrier_failures in
      btrfs_balance() lacks raid56 support.

      Reason:
       Above code was wroten in 2012-08-01, together with
       btrfs_calc_num_tolerated_disk_barrier_failures()'s first version.

       Then, btrfs_calc_num_tolerated_disk_barrier_failures() got updated
       later to support raid56, but code in btrfs_balance() was not
       updated together.

      Fix:
       Merge above similar code to a common function:
       btrfs_get_num_tolerated_disk_barrier_failures()
       and make it support both case.

       It can fix this bug with a bonus of cleanup, and make these code
       never in above no-sync state from now on.

      md/raid5: ensure device failure recorded before write request returns.

      When a write to one of the devices of a RAID5/6 fails, the failure is
      recorded in the metadata of the other devices so that after a restart
      the data on the failed drive wont be trusted even if that drive seems
      to be working again (maybe a cable was unplugged).

      Similarly when we record a bad-block in response to a write failure,
      we must not let the write complete until the bad-block update is safe.

      Currently there is no interlock between the write request completing
      and the metadata update.  So it is possible that the write will
      complete, the app will confirm success in some way, and then the
      machine will crash before the metadata update completes.

      This is an extremely small hole for a racy to fit in, but it is
      theoretically possible and so should be closed.

      So:
       - set MD_CHANGE_PENDING when requesting a metadata update for a
         failed device, so we can know with certainty when it completes
       - queue requests that completed when MD_CHANGE_PENDING is set to
         only be processed after the metadata update completes
       - call raid_end_bio_io() on bios in that queue when the time comes.

      In complicated cluster environment, it is possible that the
      dlm lock couldn't be get/convert on purpose, the related err
      info is added for better debug potential issue.

      For lockres_free, if the lock is blocking by a lock request or
      conversion request, then dlm_unlock just put it back to grant
      queue, so need to ensure the lock is free finally.

      md-cluster: fix deadlock issue on message lock

      There is problem with previous communication mechanism, and we got below
      deadlock scenario with cluster which has 3 nodes.

            writes message
         downconverts message(CR)
            requests ack(EX)
                                  get message(CR)            gets message(CR)
                                  reads message                reads message
                               requests EX on message    requests EX on message

      To fix this problem, we do the following changes:

      1. the sender downconverts MESSAGE to CW rather than CR.
      2. and the receiver request PR lock not EX lock on message.

      And in case we failed to down-convert EX to CW on message, it is better to
      unlock message otherthan still hold the lock.

      md-cluster: transfer the resync ownership to another node

      When node A stops an array while the array is doing a resync, we need
      to let another node B take over the resync task.

      To achieve the goal, we need the A send an explicit BITMAP_NEEDS_SYNC
      message to the cluster. And the node B which received that message will
      invoke __recover_slot to do resync.

      md/raid5: handle possible race as reshape completes.

      It is possible (though unlikely) for a reshape to be
      interrupted between the time that end_reshape is called
      and the time when raid5_finish_reshape is called.

      This can leave conf->reshape_progress set to MaxSector,
      but mddev->reshape_position not.

      This combination confused reshape_request() when ->reshape_backwards.
      As conf->reshape_progress is so high, it seems the reshape hasn't
      really begun.  But assuming MaxSector is a valid address only
      leads to sorrow.

      So ensure reshape_position and reshape_progress both agree,
      and add an extra check in reshape_request() just in case they don't.

      md: sync sync_completed has correct value as recovery finishes.

      There can be a small window between the moment that recovery
      actually writes the last block and the time when various sysfs
      and /proc/mdstat attributes report that it has finished.
      During this time, 'sync_completed' can have the wrong value.
      This can confuse monitoring software.

      So:
       - don't set curr_resync_completed beyond the end of the devices,
       - set it correctly when resync/recovery has completed.

      md: be careful when testing resync_max against curr_resync_completed.

      While it generally shouldn't happen, it is not impossible for
      curr_resync_completed to exceed resync_max.
      This can particularly happen when reshaping RAID5 - the current
      status isn't copied to curr_resync_completed promptly, so when it
      is, it can exceed resync_max.
      This happens when the reshape is 'frozen', resync_max is set low,
      and reshape is re-enabled.

      Taking a difference between two unsigned numbers is always dangerous
      anyway, so add a test to behave correctly if
         curr_resync_completed > resync_max

      md/raid5: remove incorrect "min_t()" when calculating writepos.

      This code is calculating:
        writepos, which is the furthest along address (device-space) that we
           *will* be writing to
        readpos, which is the earliest address that we *could* possible read
           from, and
        safepos, which is the earliest address in the 'old' section that we
           might read from after a crash when the reshape position is
           recovered from metadata.

        The first is a precise calculation, so clipping at zero doesn't
        make sense.  As the reshape position is now guaranteed to always be
        a multiple of reshape_sectors and as we already BUG_ON when
        reshape_progress is zero, there is no point in this min_t() call.

        The readpos and safepos are worst case - actual value depends on
        precise geometry.  That worst case could be negative, which is only
        a problem because we are storing the value in an unsigned.
        So leave the min_t() for those.

      md/raid5: strengthen check on reshape_position at run.

      When reshaping, we work in units of the largest chunk size.
      If changing from a larger to a smaller chunk size, that means we
      reshape more than one stripe at a time.  So the required alignment
      of reshape_position needs to take into account both the old
      and new chunk size.

      This means that both 'here_new' and 'here_old' are calculated with
      respect to the same (maximum) chunk size, so testing if they are the
      same when delta_disks is zero becomes pointless.

      md/raid5: switch to use conf->chunk_sectors in place of 
mddev->chunk_sectors where possible

      The chunk_sectors and new_chunk_sectors fields of mddev can be changed
      any time (via sysfs) that the reconfig mutex can be taken.  So raid5
      keeps internal copies in 'conf' which are stable except for a short
      locked moment when reshape stops/starts.

      So any access that does not hold reconfig_mutex should use the 'conf'
      values, not the 'mddev' values.
      Several don't.

      This could result in corruption if new values were written at awkward
      times.

      Also use min() or max() rather than open-coding.

      md/raid5: consider updating reshape_position at start of reshape.

      md/raid5 only updates ->reshape_position (which is stored in
      metadata and is authoritative) occasionally, but particularly
      when getting closed to ->resync_max as it must be correct
      when ->resync_max is reached.

      When mdadm tries to stop an array which is reshaping it will:
       - freeze the reshape,
       - set resync_max to where the reshape has reached.
       - unfreeze the reshape.
      When this happens, the reshape is aborted and then restarted.

      The restart doesn't check that resync_max is close, and so doesn't
      update ->reshape_position like it should.
      This results in the reshape stopping, but ->reshape_position being
      incorrect.

      So on that first call to reshape_request, make sure ->reshape_position
      is updated if needed.

      md: close some races between setting and checking sync_action.

      When checking sync_action in a script, we want to be sure it is
      as accurate as possible.
      As resync/reshape etc doesn't always start immediately (a separate
      thread is scheduled to do it), it is best if 'action_show'
      checks if MD_RECOVER_NEEDED is set (which it does) and in that
      case reports what is likely to start soon (which it only sometimes
      does).

      So:
       - report 'reshape' if reshape_position suggests one might start.
       - set MD_RECOVERY_RECOVER in raid1_reshape(), because that is very
         likely to happen next.

      md: Keep /proc/mdstat reporting recovery until fully DONE.

      Currently when a recovery completes, mdstat shows that it has finished
      before the new device is marked as a full member.  Because of this it
      can appear to a script that the recovery finished but the array isn't
      in sync.

      So while MD_RECOVERY_DONE is still set, keep mdstat reporting "recovery".
      Once md_reap_sync_thread() completes, the spare will be active and then
      MD_RECOVERY_DONE will be cleared.

      To ensure this is race-free, set MD_RECOVERY_DONE before clearning
      curr_resync.

      drm/i915/skl: Adding DDI_E power well domain

      From B spec, DDI_E port belong to PowerWell 2, but
      DDI_E share the powerwell_req/staus register bit with
      DDI_A which belong to DDI_A_E_POWER_WELL.

      In order to communicate with the connector on DDI-E, both
      DDI_A_E_POWER_WELL and POWER_WELL_2 must be enabled.

      Currently intel_dp_power_get(DDI_E) only enable
      DDI_A_E_POWER_WELL, this patch will not only enable

      drm/i915/skl: Enable DDI-E

      There are OEMs using DDI-E out there,
      so let's enable it.

      Unfortunately there is no detection bit for DDI-E
      So we need to rely on VBT for that.

      I also need to give credits to Xiong since before seing
      his approach to check info->support_* I was creating an ugly
      vbt->ddie_sfuse_strap in order to propagate the ddi presence info

      v2: Rebased as last patch in the series. since all other patches
      in this series are needed for anything working propperly on DDI-E.

          drm/i915: gen4: work around hang during hibernation

      using an explicit blacklist for the GENs/BIOS vendors where the issue was
      reported. Later there we had reports of the same failure on platforms not 
on
      this list.

      To my best knowledge the correct thing to do is still to put the device 
to PCI
      D3 state during hibernation, see [1] and [2] for the reasons. This also 
aligns
      with our future plans to unify more the runtime and system suspend/resume
      paths. Since an exact blacklist seems to be impractical (multiple GENs and
      BIOS vendors are affected) apply the workaround on everything pre GEN6.

      drm/i915: Check DP link status on long hpd too

      We are no longer checkling the DP link status on long hpd. We used to do
      that from the .hot_plug() handler, but it was removed when MST got
      introduced.

      If there's no userspace we now fail to retrain the link if the sink
      power is toggled (or cable yanked and replugged), meaning the user is
      left staring at a blank screen. With the retraining put back that should
      be fixed.

      Also remove the leftover comment that referred to the old retraining
      from .hot_plug().

      Fixes a regression introduced in:

      tracing: Don't make assumptions about length of string on task rename

      While the dest comm string size is assured to be at least TASK_COMM_LEN 
long,
      doing a memcpy() also adds the assumption that the source is at least that
      long as well, which isn't assured, and isn't true in cases such as:

        set_task_comm(worker->task, "kworker/dying");

      This leads to accessing invalid memory.

      spi: sh-msiof: Fix FIFO size to 64 word from 256 word

      The upper limit of Tx/Rx FIFO size is 64 word by the
      specification of H/W. This patch corrects to 64 word from 256 word.

      regmap: fix a NULL pointer dereference in __regmap_init

      __regmap_init() may receive a NULL `struct regmap_bus *bus' pointer,
      for example, from snd_hdac_regmap_init(), and it make sure that it
      does not NULL deference `bus`, except around ->max_raw_read and
      ->max_raw_write initialisation. Add missing check.

      regmap: Support bulk reads for devices without raw formatting

      When doing a bulk read from a device which lacks raw I/O support we fall
      back to doing register at a time reads but we still use the raw
      formatters in order to render the data into the word size used by the
      device (since bulk reads still operate on the device word size rather
      than unsigned ints).  This means that devices without raw formatting
      such as those that provide reg_read() are not supported.  Provide
      handling for them by copying the values read into native endian values
      of the appropriate size.

      Because in SMP, "mrq" has race condition between below two paths:
      path1: CPU0: <tasklet context>
        static void mmc_wait_data_done(struct mmc_request *mrq)
        {
           mrq->host->context_info.is_done_rcv = true;
           //
           // If CPU0 has just finished "is_done_rcv = true" in path1, and at
           // this moment, IRQ or ICache line missing happens in CPU0.
           // What happens in CPU1 (path2)?
           //
           // If the mmcqd thread in CPU1(path2) hasn't entered to sleep mode:
           // path2 would have chance to break from wait_event_interruptible
           // in mmc_wait_for_data_req_done and continue to run for next
           // mmc_request (mmc_blk_rw_rq_prep).
           //
           // Within mmc_blk_rq_prep, mrq is cleared to 0.
           // If below line still gets host from "mrq" as the result of
           // compiler, the panic happens as we traced.
           wake_up_interruptible(&mrq->host->context_info.wait);
        }

      path2: CPU1: <The mmcqd thread runs mmc_queue_thread>
        static int mmc_wait_for_data_req_done(...
        {
           ...
           while (1) {
                 wait_event_interruptible(context_info->wait,
                         (context_info->is_done_rcv ||
                          context_info->is_new_req));
                   static void mmc_blk_rw_rq_prep(...
                 {
                 ...
                 memset(brq, 0, sizeof(struct mmc_blk_request));

      This issue happens very coincidentally; however adding mdelay(1) in
      mmc_wait_data_done as below could duplicate it easily.

         static void mmc_wait_data_done(struct mmc_request *mrq)
         {
           mrq->host->context_info.is_done_rcv = true;
      +    mdelay(1);
           wake_up_interruptible(&mrq->host->context_info.wait);
          }

      At runtime, IRQ or ICache line missing may just happen at the same place
      of the mdelay(1).

      This patch gets the mmc_context_info at the beginning of function, it can
      avoid this race condition.

      netlink: rx mmap: fix POLLIN condition

      Poll() returns immediately after setting the kernel current frame
      (ring->head) to SKIP from user space even though there is no new
      frame. And in a case of all frames is VALID, user space program
      unintensionally sets (only) kernel current frame to UNUSED, then
      calls poll(), it will not return immediately even though there are
      VALID frames.

      To avoid situations like above, I think we need to scan all frames
      to find VALID frames at poll() like netlink_alloc_skb(),
      netlink_forward_ring() finding an UNUSED frame at skb allocation.

      net: thunderx: Support for upto 96 queues for a VF

      This patch adds support for handling multiple qsets assigned to a
      single VF. There by increasing no of queues from earlier 8 to max
      no of CPUs in the system i.e 48 queues on a single node and 96 on
      dual node system. User doesn't have option to assign which Qsets/VFs
       to be merged. Upon request from VF, PF assigns next free Qsets as
      secondary qsets. To maintain current behavior no of queues is kept
      to 8 by default which can be increased via ethtool.

      If user wants to unbind NICVF driver from a secondary Qset then it
      should be done after tearing down primary VF's interface.

      net: thunderx: Support for HW VLAN stripping

      This patch configures HW to strip 802.1Q header if found in a
      receiving packet. The stripped VLAN ID and TCI information is
      passed on to software via CQE_RX. Also sets netdev's 'vlan_features'
      so that other HW offload features can be used for tagged packets.

      This offload feature can be enabled or disabled via ethtool.

      Network stack normally ignores RPS for 802.1Q packets and hence low
      throughput. With this offload enabled throughput for tagged packets
      will be almost same as normal packets.

      Note: This patch doesn't enable HW VLAN insertion for transmit packets.

      Merge branch 'snmp-stat-aggregation'

      Raghavendra K T says:

      ====================
      Optimize the snmp stat aggregation for large cpus

      While creating 1000 containers, perf is showing lot of time spent in
      snmp_fold_field on a large cpu system.

      The current patch tries to improve by reordering the statistics gathering.

      Please note that similar overhead was also reported while creating
      veth pairs  https://lkml.org/lkml/2013/3/19/556

      Changes in V4:
       - remove 'item' variable and use IPSTATS_MIB_MAX to avoid sparse
         warning (Eric) also remove 'item' parameter (Joe)
       - add missing memset of padding.

      Changes in V3:
       - use memset to initialize temp buffer in leaf function. (David)
       - use memcpy to copy the buffer data to stat instead of unalign_pu (Joe)
       - Move buffer definition to leaf function __snmp6_fill_stats64() (Eric)
       -
      Changes in V2:
       - Allocate the stat calculation buffer in stack. (Eric)

      Setup:
      160 cpu (20 core) baremetal powerpc system with 1TB memory

      1000 docker containers was created with command
      docker run -itd  ubuntu:15.04  /bin/bash in loop

      observation:
      Docker container creation linearly increased from around 1.6 sec to 7.5 
sec
      (at 1000 containers) perf data showed, creating veth interfaces resulting 
in
      the below code path was taking more time.

      rtnl_fill_ifinfo
        -> inet6_fill_link_af
          -> inet6_fill_ifla6_attrs
            -> snmp_fold_field

      proposed idea:
       currently __snmp6_fill_stats64 calls snmp_fold_field that walks
      through per cpu data to of an item (iteratively for around 36 items).
       The patch tries to aggregate the statistics by going through
      all the items of each cpu sequentially which is reducing cache
      misses.

      Performance of docker creation improved by around more than 2x
      after the patch.

      net: Optimize snmp stat aggregation by walking all the percpu data at once

      Docker container creation linearly increased from around 1.6 sec to 7.5 
sec
      (at 1000 containers) and perf data showed 50% ovehead in snmp_fold_field.

      reason: currently __snmp6_fill_stats64 calls snmp_fold_field that walks

      NFSv4.1: Fix a protocol issue with CLOSE stateids

      According to RFC5661 Section 18.2.4, CLOSE is supposed to return
      the zero stateid. This means that nfs_clear_open_stateid_locked()
      cannot assume that the result stateid will always match the 'other'
      field of the existing open stateid when trying to determine a race
      with a parallel OPEN.

      Instead, we look at the argument, and check for matches.

      alpha: select CONFIG_ARCH_USE_CMPXCHG_LOCKREF.

      On Alpha we have spinlocks that are 32b in size and an efficient
      cmpxchg64 implementation, so we qualify to make use of cmpxchg backed
      lockrefs. Select the ARCH_USE_CMPXCHG_LOCKREF Kconfig symbol and provide
      a trivial implementation of arch_spin_value_unlocked to satisfy the

      IB/ucma: HW Device hot-removal support

      Currently, IB/cma remove_one flow blocks until all user descriptor 
managed by
      IB/ucma are released. This prevents hot-removal of IB devices. This patch
      allows IB/cma to remove devices regardless of user space activity. Upon 
getting
      the RDMA_CM_EVENT_DEVICE_REMOVAL event we close all the underlying HW 
resources
      for the given ucontext. The ucontext itself is still alive till its 
explicit
      destroying by its creator.

      Running applications at that time will have some zombie device, further
      operations may fail.

      IB/mlx4_ib: Disassociate support

      Implements the IB core disassociate_ucontext API. The driver detaches the 
HW
      resources for a given user context to prevent a dependency between 
application
      termination and device disconnecting. This is done by managing the VMAs 
that
      were mapped to the HW bars such as door bell and blueflame. When need to 
detach
      remap them to an arbitrary kernel page returned by the zap API.

      IB/uverbs: Enable device removal when there are active user space 
applications

      Enables the uverbs_remove_one to succeed despite the fact that there are
      running IB applications working with the given ib device.  This
      functionality enables a HW device to be unbind/reset despite the fact that
      there are running user space applications using it.

      It exposes a new IB kernel API named 'disassociate_ucontext' which lets
      a driver detaching its HW resources from a given user context without
      crashing/terminating the application. In case a driver implemented the
      above API and registered with ib_uverb there will be no dependency 
between its
      device to its uverbs_device. Upon calling remove_one of ib_uverbs the call
      should return after disassociating the open HW resources without waiting 
to
      clients disconnecting. In case driver didn't implement this API there 
will be no
      change to current behaviour and uverbs_remove_one will return only when 
last
      client has disconnected and reference count on uverbs device became 0.

      In case the lower driver device was removed any application will
      continue working over some zombie HCA, further calls will ended with an
      immediate error.

      IB/uverbs: Fix race between ib_uverbs_open and remove_one

      Fixes: 2a72f212263701b927559f6850446421d5906c41 ("IB/uverbs: Remove 
dev_table")

      Before this commit there was a device look-up table that was protected
      by a spin_lock used by ib_uverbs_open and by ib_uverbs_remove_one. When
      it was dropped and container_of was used instead, it enabled the race
      with remove_one as dev might be freed just after:
      dev = container_of(inode->i_cdev, struct ib_uverbs_device, cdev) but
      before the kref_get.

      In addition, this buggy patch added some dead code as
      container_of(x,y,z) can never be NULL and so dev can never be NULL.
      As a result the comment above ib_uverbs_open saying "the open method
      will either immediately run -ENXIO" is wrong as it can never happen.

      The solution follows Jason Gunthorpe suggestion from below URL:
      https://www.mail-archive.com/linux-rdma@xxxxxxxxxxxxxxx/msg25692.html

      cdev will hold a kref on the parent (the containing structure,
      ib_uverbs_device) and only when that kref is released it is
      guaranteed that open will never be called again.

      In addition, fixes the active count scheme to use an atomic
      not a kref to prevent WARN_ON as pointed by above comment
      from Jason.

      IB/core: Make ib_dealloc_pd return void

      The majority of callers never check the return value, and even if they
      did, they can't do anything about a failure.

      All possible failure cases represent a bug in the caller, so just
      WARN_ON inside the function instead.

      This fixes a few random errors:
       net/rd/iw.c infinite loops while it fails. (racing with EBUSY?)

      This also lays the ground work to get rid of error return from the
      drivers. Most drivers do not error, the few that do are broken since
      it cannot be handled.

      Since uverbs can legitimately make use of EBUSY, open code the
      check.

      Do not create an all physical MR unless it is needed to support

      IB/iser: Support up to 8MB data transfer in a single command

      iser support up to 512KB data transfer in a single scsi command.
      This means that larger IOs will split to different request. While
      iser can easily saturate FDR/EDR wires, some arrays are fine tuned
      for 1MB (or larger) IO sizes, hence add an option to support larger
      transfers (up to 8MB) if the device allows it.

      Given that a few target implementations don't support data transfers
      of more than 512KB by default and the fact that larger IO sizes require
      more resources, we introduce a module parameter to determine the
      maximum number of 512B sectors in a single scsi command.
      Users that are interested in larger transfers can change this value given
      that the target supports larger transfers.

      At the moment, iser works in 4K pages granularity, In a later stage
      we will get it to work with system page size instead.

      IO operations that consists of N pages will need a page vector
      of size N+1 in case the first SG element contains an offset. Given
      that some devices allocates memory regions in powers of 2, this
      means that allocating a region with N+1 pages, will result in
      region resources allocation of the next power of 2. Since we don't
      want that to happen, in case we are in the limit of IO size supported
      and the first SG element has an offset, we align the SG list using a
      bounce buffer (which is OK given that this is not likely to happen a lot).

      IB/iser: Remove dead code in fmr_pool alloc/free

      In the past the we always tried to allocate an fmr_pool
      and if it failed on ENOSYS (not supported) then we continued
      with dma mr. This is not the case anymore and if we tried to
      allocate an fmr_pool then it is supported and we expect to succeed.

      Also, the check if fmr_pool is allocated when free is called is
      redundant as well as we are guaranteed it exists.

      IB/iser: Introduce struct iser_reg_resources

      Have fast_reg_descriptor hold struct iser_reg_resources
      (mr, frpl, valid flag). This will be useful when the
      actual buffer registration routines will be passed with
      the needed registration resources (i.e. iser_reg_resources)
      without being aware of their nature (i.e. data or protection).

      In order to achieve this, we remove reg_indicators flags container
      and place specific flags (mr_valid) within iser_reg_resources struct.
      We also place the sig_mr_valid and sig_protcted flags in iser_pi_context.

      This patch also modifies iser_fast_reg_mr to receive the
      reg_resources instead of the fast_reg_descriptor and a data/protection
      indicator.

      listener is not present, the request will be sent through IB, just like

      IB/mlx4: Fix incorrect cq flushing in error state

      When handling a device internal error, the driver is responsible to
      drain the completion queue with flush errors.

      In case a completion queue was assigned to multiple send queues, the
      driver iterates over the send queues and generates flush errors of
      inflight wqes. The driver must correctly pass the wc array with an
      offset as a result of the previous send queue iteration. Not doing so
      will overwrite previously set completions and return a wrong number
      of polled completions which includes ones which were not correctly set.

      net/mlx4: Postpone the registration of net_device

      The mlx4 network driver was registered in the context of the 'add'

      This makes the netdev event NETDEV_REGISTER to be sent in a context

      IB/core: Add RoCE table bonding support

      Handling bonding and other devices require us to all all GIDs of the
      net-devices which are upper-devices of the RoCE port related
      net-device.

      Active-backup configurations imposes even more challenges as the
      default GID should only be set on the active devices (this is
      necessary as otherwise the same MAC could be used for several
      slaves and thus several slaves will have identical GIDs).

      Managing these configurations are done by listening to:
      (a) NETDEV_CHANGEUPPER event
        (1) if a related net-device is linked, delete all inactive
            slaves default GIDs and add the upper device GIDs.
        (2) if a related net-device is unlinked, delete all upper GIDs
            and add the default GIDs.
      (b) NETDEV_BONDING_FAILOVER:
        (1) delete the bond GIDs from inactive slaves
        (2) delete the inactive slave's default GIDs
        (3) Add the bond GIDs to the active slave.

      IB/core: Add RoCE GID table management

      RoCE GIDs are based on IP addresses configured on Ethernet net-devices
      which relate to the RDMA (RoCE) device port.

      Currently, each of the low-level drivers that support RoCE (ocrdma,
      mlx4) manages its own RoCE port GID table. As there's nothing which is
      essentially vendor specific, we generalize that, and enhance the RDMA
      core GID cache to do this job.

      In order to populate the GID table, we listen for events:

      (a) netdev up/down/change_addr events - if a netdev is built onto
          our RoCE device, we need to add/delete its IPs. This involves
          adding all GIDs related to this ndev, add default GIDs, etc.

      (b) inet events - add new GIDs (according to the IP addresses)
          to the table.

      For programming the port RoCE GID table, providers must implement
      the add_gid and del_gid callbacks.

      RoCE GID management requires us to state the associated net_device
      alongside the GID. This information is necessary in order to manage
      the GID table. For example, when a net_device is removed, its
      associated GIDs need to be removed as well.

      RoCE mandates generating a default GID for each port, based on the
      related net-device's IPv6 link local. In contrast to the GID based on
      the regular IPv6 link-local (as we generate GID per IP address),
      the default GID is also available when the net device is down (in
      order to support loopback).

      Locking is done as follows:
      The patch modify the GID table code both for new RoCE drivers
      implementing the add_gid/del_gid callbacks and for current RoCE and
      IB drivers that do not. The flows for updating the table are
      different, so the locking requirements are too.

      While updating RoCE GID table, protection against multiple writers is
      achieved via mutex_lock(&table->lock). Since writing to a table
      requires us to find an entry (possible a free entry) in the table and
      then modify it, this mutex protects both the find_gid and write_gid
      ensuring the atomicity of the action.
      Each entry in the GID cache is protected by rwlock. In RoCE, writing
      (usually results from netdev notifier) involves invoking the vendor's
      add_gid and del_gid callbacks, which could sleep.
      Therefore, an invalid flag is added for each entry. Updates for RoCE are
      done via a workqueue, thus sleeping is permitted.

      In IB, updates are done in write_lock_irq(&device->cache.lock), thus
      write_gid isn't allowed to sleep and add_gid/del_gid are not called.

      When passing net-device into/out-of the GID cache, the device
      is always passed held (dev_hold).

      The code uses a single work item for updating all RDMA devices,
      following a netdev or inet notifier.

      The patch moves the cache from being a client (which was incorrect,
      as the cache is part of the IB infrastructure) to being explicitly
      initialized/freed when a device is registered/removed.

      For loopback purposes, RoCE devices should have a default GID in the

      we use the IPv6 link local address which would have been genenrated
      for the related Ethernet netdevice when it goes up as a default GID.

      addrconf_ifid_eui48 is used to gernerate this address, export it.

      IB/cma: Refactor RDMA IP CM private-data parsing code

      When receiving a connection request, rdma_cm needs to associate the 
request
      with a network device, in order to disambiguate requests. To do this, it
      needs to know the request's destination IP. For this the module needs to
      allow getting this information from the private data in the request 
packet,
      instead of relying on the information already being in the listening RDMA
      CM ID.

      When creating a new incoming connection ID, the code in
      cma_save_ip{4,6}_info can no longer rely on the listener's private data to
      find the port number, so it reads it from the requested service ID.

      IB/cm: Share listening CM IDs

      Enabling network namespaces for RDMA CM will allow processes on different
      namespaces to listen on the same port. In order to leave namespace support
      out of the CM layer, this requires that multiple RDMA CM IDs will be able
      to share a single CM ID.

      This patch adds infrastructure to retrieve an existing listening ib_cm_id,
      based on its device and service ID, or create a new one if one does not
      already exist. It also adds a reference count for such instances
      (cm_id_private.listen_sharecount), and prevents cm_destroy_id from
      destroying a CM if it is still shared. See the relevant discussion [1].

      IB/core: Find the network device matching connection parameters

      In the case of IPoIB, and maybe in other cases, the network device is
      managed by an upper-layer protocol (ULP). In order to expose this
      network device to other users of the IB device, let ULPs implement
      a callback that returns network device according to connection parameters.

      The IB device and port, together with the P_Key and the GID should
      be enough to uniquely identify the ULP net device. However, in current
      kernels there can be multiple IPoIB interfaces created with the same GID.
      Furthermore, such configuration may be desireable to support ipvlan-like
      configurations for RDMA CM with IPoIB.  To resolve the device in these
      cases the code will also take the IP address as an additional input.

      IB/core: lock client data with lists_rwsem

      An ib_client callback that is called with the lists_rwsem locked only for
      read is protected from changes to the IB client lists, but not from
      ib_unregister_device() freeing its client data. This is because
      ib_unregister_device() will remove the device from the device list with
      lists_rwsem locked for write, but perform the rest of the cleanup,
      including the call to remove() without that lock.

      Mark client data that is undergoing de-registration with a new going_down
      flag in the client data context. Lock the client data list with 
lists_rwsem
      for write in addition to using the spinlock, so that functions calling the
      callback would be able to lock only lists_rwsem for read and let callbacks
      sleep.

      Since ib_unregister_client() now marks the client data context, no need 
for
      remove() to search the context again, so pass the client data directly to
      remove() callbacks.

      IB/core: Add rwsem to allow reading device list or client list

      Currently the RDMA subsystem's device list and client list are protected 
by
      a single mutex. This prevents adding user-facing APIs that iterate these
      lists, since using them may cause a deadlock. The patch attempts to solve
      this problem by adding a read-write semaphore to protect the lists. 
Readers
      now don't need the mutex, and are safe just by read-locking the semaphore.

      The ib_register_device, ib_register_client, ib_unregister_device, and
      ib_unregister_client functions are modified to lock the semaphore for 
write
      during their respective list modification. Also, in order to make sure
      client callbacks are called only between add() and remove() calls, the 
code
      is changed to only add items to the lists after the add() calls and remove
      from the lists before the remove() calls.

      This patch attempts to solve a similar need [1] that was seen in the RoCE
      v2 patch series.

      The atomic modesetting interfaces supports async commits that should be
      implemented by the drivers. If drm core requests an async commit
      exynos_atomic_commit() will now schedule a work task to run the update 
later.

      It also serializes commits that needs to run on the same crtc, putting the
      following commit to wait until the current one is finished.

      drm/exynos: fimd: only finish update if START == START_S

      fimd_update_plane() programs BUF_START[win] and during the update
      BUF_START[win] is copied to BUF_START_S[win] (its shadow register)
      and starts scanning out, then it raises a irq.

      The fimd_irq_handler, in the case we have a pending_fb, will check
      the fb value was copied to START_S register and finish the update
      in case of success.

      Based on patch from Daniel Kurtz <djkurtz@xxxxxxxxxxxx>

      drm/exynos: check for pending fb before finish update

      The current code was ignoring the end of update for all overlay planes,
      caring only for the primary plane update in case of pageflip.

      This change adds a change to start to check for pending updates for all
      planes through exynos_plane->pending_fb. At the start of plane update the
      pending_fb is set with the fb to be shown on the screen. Then only when to
      fb is already presented in the screen we set pending_fb to NULL to
      signal that the update was finished.

      drm/exynos: add prepare and cleanup phases for planes

      From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

      .prepare_plane() and .cleanup_plane() allows to perform extra operations
      before and after the update of planes. For FIMD for example this will
      be used to enable disable the shadow protection bit.

      cxl: Fix force unmapping mmaps of contexts allocated through the kernel 
api

      The cxl user api uses the address_space associated with the file when we
      need to force unmap all cxl mmap regions (e.g. on eeh, driver detach,
      etc). Currently, contexts allocated through the kernel api do not do
      this and instead skip the mmap invalidation, potentially allowing them
      to poke at the hardware after such an event, which may cause all sorts
      of trouble.

      This patch allocates an address_space for cxl contexts allocated through
      the kernel api so that the same invalidate path will for these contexts
      as well. We don't use the anonymous inode's address_space, as doing so
      could invalidate any mmaps of completely unrelated drivers using
      anonymous file descriptors.

      This patch also introduces a kernelapi flag, so we know when freeing the
      context if the address_space was allocated by us and needs to be freed.

      This patch switches to using goto style error handling so that the
      device is released in common code for both error paths, and will also
      simplify things if we add additional initialisation in this function in
      the future.

      tunnels: fix incorrect IPv4/v6 headers interpretation

      With tunneling, it is currently possible to get an IPv6 header and 
interpret

      (and vice versa). This leads to things like sending packets to incorrect
      address, IPv6 flow label being interpreted as IP packet length, etc.

      doesn't seem there's anything in user space that sets the attribute at all
      currently, thus net-next is fine.

      vxlan: do not receive IPv4 packets on IPv6 socket

      By default (subject to the sysctl settings), IPv6 sockets listen also for
      IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in
      packets received through an IPv6 socket.

      In addition, it's currently not possible to have both IPv4 and IPv6 vxlan
      tunnel on the same port (unless bindv6only sysctl is enabled), as it's not
      possible to create and bind both IPv4 and IPv6 vxlan interfaces and 
there's
      no way to specify both IPv4 and IPv6 remote/group IP addresses.

      Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not
      done globally in udp_tunnel, as l2tp and tipc seems to work okay when
      receiving IPv4 packets on IPv6 socket and people may rely on this 
behavior.
      The other tunnels (geneve and fou) do not support IPv6.

      fou: reject IPv6 config

      fou does not really support IPv6 encapsulation. After an UDP socket is
      created in fou_create, the encap_rcv callback is set either to 
fou_udp_recv
      or to gue_udp_recv. Both of those unconditionally assume that the received
      packet has an IPv4 header and access the data at network_header as it was 
an
      IPv4 header. This leads to IPv6 flow label being interpreted as IP packet
      length, etc.

      Disallow fou tunnel to be configured as IPv6 until real IPv6 support is
      added to fou.

      ip_tunnels: record IP version in tunnel info

      There's currently nothing preventing directing packets with IPv6
      encapsulation data to IPv4 tunnels (and vice versa). If this happens,
      IPv6 addresses are incorrectly interpreted as IPv4 ones.

      Track whether the given ip_tunnel_key contains IPv4 or IPv6 data. Store 
this
      in ip_tunnel_info. Reject packets at appropriate places if they are 
supposed
      to be encapsulated into an incompatible protocol.

      The mode field holds a single bit of information only (whether the

flags.
      This allows more mode flags to be added.

      ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc 
failure

      In PCM core, when hw_params() in each driver returns error, the state of
      PCM substream is kept as 'open'. In this case, current drivers for sound
      units on IEEE 1394 bus doesn't decrement substream counter in hw_free()
      correctly. This causes these drivers to keep streams even if not
      required.

      This commit fixes this bug. When snd_pcm_lib_alloc_vmalloc_buffer()
      fails, hw_params function in each driver returns without incrementing the
      counter.

      libnvdimm, pmem: direct map legacy pmem by default

      The expectation is that the legacy / non-standard pmem discovery method
      (e820 type-12) will only ever be used to describe small quantities of
      persistent memory.  Larger capacities will be described via the ACPI
      NFIT.  When "allocate struct page from pmem" support is added this default
      policy can be overridden by assigning a legacy pmem namespace to a pfn
      device, however this would be only be necessary if a platform used the
      legacy mechanism to define a very large range.

      libnvdimm, pmem: 'struct page' for pmem

      Enable the pmem driver to handle PFN device instances.  Attaching a pmem
      namespace to a pfn device triggers the driver to allocate and initialize
      struct page entries for pmem.  Memory capacity for this allocation comes
      exclusively from RAM for now which is suitable for low PMEM to RAM
      ratios.  This mechanism will be expanded later for setting an "allocate
      from PMEM" policy.

      libnvdimm, pfn: 'struct page' provider infrastructure

      Implement the base infrastructure for libnvdimm PFN devices. Similar to
      BTT devices they take a namespace as a backing device and layer
      functionality on top. In this case the functionality is reserving space
      for an array of 'struct page' entries to be handed out through
      pfn_to_page(). For now this is just the basic libnvdimm-device-model for
      configuring the base PFN device.

      As the namespace claiming mechanism for PFN devices is mostly identical
      to BTT devices drivers/nvdimm/claim.c is created to house the common
      bits.

      RDMA/cma: fix IPv6 address resolution

      Resolving a link-local IPv6 address with an unspecified source address
      was broken by commit 5462eddd7a, which prevented the IPv6 stack from
      learning the scope id of the link-local IPv6 address, causing random
      failures as the IP stack chose a random link to resolve the address on.

      This commit 5462eddd7a made us bail out of cma_check_linklocal early if
      the address passed in was not an IPv6 link-local address. On the address
      resolution path, the address passed in is the source address; if the
      source address is the unspecified address, which is not link-local, we
      will bail out early.

      This is mostly correct, but if the destination address is a link-local
      address, then we will be following a link-local route, and we'll need to
      tell the IPv6 stack what the scope id of the destination address is.
      This used to be done by last line of cma_check_linklocal, which is
      skipped when bailing out early:

        dev_addr->bound_dev_if = sin6->sin6_scope_id;

      (In cma_bind_addr, the sin6_scope_id of the source address is set to the
      sin6_scope_id of the destination address, so this is correct)
      This line is required in turn for the following line, L279 of
      addr6_resolve, to actually inform the IPv6 stack of the scope id:

            fl6.flowi6_oif = addr->bound_dev_if;

      Since we can only know we are in this failure case when we have access
      to both the source IPv6 address and destination IPv6 address, we have to
      deal with this further up the stack. So detect this failure case in
      cma_bind_addr, and set bound_dev_if to the destination address scope id
      to correct it.

      tools: cpupower: Fix error when running cpupower monitor

      get_cpu_topology() tries to get topology info from all cpus by reading
      files in the topology sysfs dir. If a cpu is offlined, since it doesn't
      have topology dir, this function fails and returns -1. This causes
      functions relying on get_cpu_topology() to fail. For example-

      $ cpupower monitor
      Cannot read number of available processors

      Fix this by skipping fetching topology info for offline cpus.

      Netfilter updates for net-next

      The following patchset contains Netfilter/IPVS updates for your net-next 
tree.
      In sum, patches to address fallout from the previous round plus updates 
from
      the IPVS folks via Simon Horman, they are:

      1) Add a new scheduler to IPVS: The weighted overflow scheduling algorithm
         directs network connections to the server with the highest weight that 
is
         currently available and overflows to the next when active connections 
exceed
         the node's weight. From Raducu Deaconu.

      2) Fix locking ordering in IPVS, always take rtnl_lock in first place. 
Patch
         from Julian Anastasov.

      3) Allow to indicate the MTU to the IPVS in-kernel state sync daemon. From
         Julian Anastasov.

      4) Enhance multicast configuration for the IPVS state sync daemon. Also 
from
         Julian.

      5) Resolve sparse warnings in the nf_dup modules.

      6) Fix a linking problem when CONFIG_NF_DUP_IPV6 is not set.

      7) Add ICMP codes 5 and 6 to IPv6 REJECT target, they are more informative
         subsets of code 1. From Andreas Herz.

      8) Revert the jumpstack size calculation from mark_source_chains due to 
chain
         depth miscalculations, from Florian Westphal.

      9) Calm down more sparse warning around the Netfilter tree, again from 
Florian
         Westphal.

      netfilter: nfnetlink: work around wrong endianess in res_id field

      The convention in nfnetlink is to use network byte order in every header 
field
      as well as in the attribute payload. The initial version of the batching
      infrastructure assumes that res_id comes in host byte order though.

      The only client of the batching infrastructure is nf_tables, so let's add 
a
      workaround to address this inconsistency. We currently have 11 nfnetlink
      subsystems according to NFNL_SUBSYS_COUNT, so we can assume that the 
subsystem
      2560, ie. htons(10), will not be allocated anytime soon, so it can be an 
alias
      of nf_tables from the nfnetlink batching path when interpreting the res_id
      field.

      Based on original patch from Florian Westphal.

      sfc: Allow driver to cope with a lower number of VIs than it needs for RSS

      Previously, the driver would refuse to load if it couldn't secure
      enough VIs from the MC to fulfill its RSS requirements.
      This was causing probe to fail on later functions in
      configurations where we'd run out of VIs, such as having many
      VFs.

      This change allows the driver to load with fewer VIs, down to a
      minimum of 2. A warning will be printed saying that RSS
      requirements were not met, possibly affecting performance.

      efx->max_tx_channels needs to be set to avoid going down the
      failure path in efx_probe_nic() immediately in the loop after the
      probe() NIC-type function.
      Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack
      of VIs.

      IGMP: Inhibit reports for local multicast groups

      The range of addresses between 224.0.0.0 and 224.0.0.255 inclusive, is
      reserved for the use of routing protocols and other low-level topology
      discovery or maintenance protocols, such as gateway discovery and
      group membership reporting.  Multicast routers should not forward any
      multicast datagram with destination addresses in this range,
      regardless of its TTL.

      Currently, IGMP reports are generated for this reserved range of
      addresses even though a router will ignore this information since it
      has no purpose.  However, the presence of reserved group addresses in
      an IGMP membership report uses up network bandwidth and can also
      obscure addresses of interest when inspecting membership reports using
      packet inspection or debug messages.

      Although the RFCs for the various version of IGMP (e.g.RFC 3376 for
      v3) do not specify that the reserved addresses be excluded from
      membership reports, it should do no harm in doing so.  In particular
      there should be no adverse effect in any IGMP snooping functionality
      since 224.0.0.x is specifically excluded as per RFC 4541 (IGMP and MLD
      Snooping Switches Considerations) section 2.1.2. Data Forwarding
      Rules:

          2) Packets with a destination IP (DIP) address in the 224.0.0.X
             range which are not IGMP must be forwarded on all ports.

      IGMP reports for local multicast groups can now be optionally
      inhibited by means of a system control variable (by setting the value
      to zero) e.g.:
          echo 0 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports

      To retain backwards compatibility the previous behaviour is retained
      by default on system boot or reverted by setting the value back to
      non-zero e.g.:
          echo 1 >  /proc/sys/net/ipv4/igmp_link_local_mcast_reports

      r8169: Add software counter for multicast packages

      The multicast hardware counter on 8168/8111 chips is only 32 bit while the
      statistics in struct rtnl_link_stats64 are 64 bit.  Given that statistics
      are requested on an irregular basis, an overflow of the hardware counter
      can go unnoticed.  To count even very large numbers of multicast packets
      reliably, add a software counter and remove previously applied code to
      fill the multicast field requested by @rtl8169_get_stats64 with the values
      read from the rx_multicast hardware counter.

      scsi_dh: integrate into the core SCSI code

      Stop building scsi_dh as a separate module and integrate it fully into the

      callouts are placed at the same point as the old bus notifiers were 
called,
      but in the future we will be able to look at ALUA INQUIRY data earlier on.

      Note that this also means that the device handler modules need to be 
loaded
      by the time we scan the bus.  The next patches will add support for
      autoloading device handlers at bus scan time to make sure they are always
      loaded if they are enabled in the kernel config.

      Bluetooth: Fix SCO link type handling on connection complete

      Synchronous connections are initially created with type eSCO.
      Link manager may reject proposed link parameters, which triggers
      connection setup retry with a different set. Link type embedded
      in responses should be disregarded until Synchronous Connect Complete
      returns Success (0x00). Current code updates link type every time
      which creates an issue when link type changes to SCO and back to eSCO
      on further attepts.

      Issue happens with BlackBerry 9100 and 9700 with Intel WilkinsPeak
      on third connection setup attept

      Bluetooth: hci_intel: Add support for platform driver

      A platform device can be used to provide some specific resources in
      order to manage the controller. In this first patch we retrieve the
      reset gpio which is used to power on/off the controller.

      The main issue is to match the current tty with the correct pdev.
      In case of ACPI, we can easily find the right tty/pdev pair because
      they are both child of the same UART port.

      If controller is powered-on from the driver, we need to wait for a
      HCI boot event before being able to send any command.

      Bluetooth: hci_intel: Add Intel baudrate configuration support

      Implement the set_baudrate callback for hci_intel.
       - Controller requires a read Intel version command before updating
         its baudrate.
       - The operation consists in an async cmd since the controller does
         not respond at the same speed.
       - Wait 100ms to let the controller change its baudrate.
       - Clear RTS until we change our own UART speed

      Manage speed change in the setup function, we need to restore the oper
      speed once chip has booted on patched firmware.

      perf scripts python: Add new compaction-times script

      This patch creates a new script (compaction-times) to report time
      spent in mm compaction. It is possible to report times in nanoseconds
      (default) or microseconds (-u).

      The option -p will break down results by process id, -pv will further
      decompose by each compaction entry/exit.

      For each compaction entry/exit what is reported is controlled by the
      options:

        -t   report only timing
        -m   report migration stats
        -ms  report migration scanner stats
        -fs  report free scanner stats

      The default is to report all.

      Entries may be further filtered by pid, pid-range or comm (regex).

      The script is useful when analysing workloads that compact memory. The
      most common example will be THP allocations on systems with a lot of
      uptime that has fragmented memory.

      This is an example of using the script to analyse a thpscale from
      mmtests which deliberately fragments memory and allocates THP in 4
      separate threads

      thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macro

      vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses
      no_printk which produces no logging output but always
      evaluates arguments.

      Change the macro to surround the no_printk call with
        do { if (0) no_printk(...); } while (0)
      to avoid the unnecessary argument evaluations.

      regulator: core: use debug level print in regulator_check_drms

      When calling regulator_set_load, regulator_check_drms prints and returns
      an error if the regulator device's flag REGULATOR_CHANGE_DRMS isn't set.
      drms_uA_update, however, bails out without reporting an error.

      Replace the error print with a debug level print so that we don't get
      such prints when the underlying regulator doesn't support DRMS.

      This is because when extent cache is disable, extent_tree pointer in 
struct
      f2fs_inode_info should be NULL, but in f2fs_drop_largest_extent we access
      this NULL pointer directly without checking state of extent cache, then,
      the oops occurs. Let's fix it by checking state of extent cache before
      accessing.

      scripts: add stackdelta script

      This adds a simple perl script for reading two files as produced by
      the stackusage script and computing the changes in stack usage. For
      example:

      $ scripts/stackusage -o /tmp/old.su CC=gcc-4.7 -j8 fs/ext4/
      $ scripts/stackusage -o /tmp/new.su CC=gcc-5.0 -j8 fs/ext4/
      $ scripts/stackdelta /tmp/{old,new}.su | sort -k5,5g

      shows that gcc 5.0 generally produces less stack-hungry code than gcc
      4.7. Obviously, the script can also be used for measuring the effect
      of commits, .config tweaks or whatnot.

      scripts: add stackusage script

      The current checkstack.pl script has a few problems, stemming from the
      overly simplistic attempt at parsing objdump output with regular
      expressions: For example, on x86_64 it doesn't take the push
      instruction into account, making it consistently underestimate the
      real stack use, and it also doesn't capture stack pointer adjustments
      of exactly 128 bytes [1].

      Since newer gcc (>= 4.6) knows about -fstack-usage, we might as well
      take the information straight from the horse's mouth. This patch
      introduces scripts/stackusage, which is a simple wrapper for running
      make with KCFLAGS set to -fstack-usage. Example use is

      scripts/stackusage -o out.su -j8 lib/

      The script understands "-o foo" for writing to 'foo' and -h for a
      trivial help text; anything else is passed to make.

      Afterwards, we find all newly created .su files, massage them a
      little, sort by stack use and write the result to a single output
      file.

      Note that the function names printed by (at least) gcc 4.7 are
      sometimes useless. For example, the first three lines of out.su
      generated above are

      ./lib/decompress_bunzip2.c:155  get_next_block  448     static
      ./lib/decompress_unlzma.c:537   unlzma  336     static
      ./lib/vsprintf.c:616    8       304     static

      That function '8' is really the static symbol_string(), but it has
      been subject to 'interprocedural scalar replacement of aggregates', so
      its name in the object file is 'symbol_string.isra.8'. gcc 5.0 doesn't
      have this problem; it uses the full name as seen in the object file.

      [1] Since gcc encodes that by

      48 83 c4 80             add    $0xffffffffffffff80,%rsp

      and not

      48 81 ec 80 00 00 00    sub    $0x80,%rsp

      since -128 fits in an imm8.

      perf stat: Get correct cpu id for print_aggr

      print_aggr() fails to print per-core/per-socket statistics after commit
      582ec0829b3d ("perf stat: Fix per-socket output bug for uncore events")
      if events have differnt cpus. Because in print_aggr(), aggr_get_id needs
      index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be
      used to get aggregated id.

      Here is an example:

      Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has
      cpumask 0,18)

        $ perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core 
sleep 2

      Without this patch, it failes to get CPU 18 result.

         Performance counter stats for 'CPU(s) 0,18':

        S0-C0           1            7526851      cycles
        S0-C0           1               1.05 MiB  uncore_imc_0/cas_count_read/
        S1-C0           0      <not counted>      cycles
        S1-C0           0      <not counted> MiB  uncore_imc_0/cas_count_read/

      With this patch, it can get both CPU0 and CPU18 result.

         Performance counter stats for 'CPU(s) 0,18':

        S0-C0           1            6327768      cycles

      leds: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
      regardless of the mechanism that was used to register the device
      (i.e: OF or board code) and the table that is used later to match
      the driver with the device (i.e: I2C id table or OF match table).

      So drivers needs to export the I2C id table and this be built into
      the module or udev won't have the necessary information to autoload
      the needed driver module when the device is added.

      But this means that OF-only drivers needs to have both OF and I2C id
      tables that have to be kept in sync and also the dev node compatible
      manufacturer prefix is stripped when reporting the MODALIAS. Which can
      lead to issues if two vendors use the same I2C device name for example.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an SPI device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table even when
      is unused now to prevent breaking module loading when the core changes.

      leds:lp55xx: use the private data instead of updating I2C device platform 
data

      Currently, lp55xx_of_populate_pdata() allocates lp55xx_platform_data if
      it's null. And it parses the DT and copies values into the
      'client->dev.platform_data'. This may have architectural issue.
      Platform data is configurable through the DT or I2C board info inside the
      platform area. However, lp55xx common driver changes this configuration
      when it is loaded. So 'client->dev.platform_data' is not null anymore.
      Eventually, the driver initialization is not identical when it's unloaded
      and loaded again.
      The lp55xx common driver should use the private data, 'lp55xx_chip->pdata'
      instead of changing the original platform data.

      So, lp55xx_of_populate_pdata() is modified as follows.
      * Do not update 'dev->platform_data'. Return the pointer of new allocated
         lp55xx_platform_data. Then the driver points it to private data,
         'lp55xx_chip->pdata'.
      * Each lp55xx driver checks the pointer and handles an error case.

      Then, original platform data configuration will be kept regardless of
      loading or unloading the driver.
      The driver allocates the memory and copies them from the DT if it's NULL.
      After the driver is loaded again, 'client->dev.platform_data' is same as
      initial load, so the driver is initialized identically.

      ARM: Kirkwood: add modes-map property to ns2-leds nodes

      Since the LED modes mapping is no longer hardcoded inside the leds-ns2
      driver, then it must be provided through the modes-map property in the
      ns2-leds nodes.

      leds: leds-ns2: handle can_sleep GPIOs

      On the board n090401 (Seagate NAS 4-Bay), some of the LEDs are handled
      by the leds-ns2 driver. This LEDs are connected to an I2C GPIO expander
      (PCA95554PW) which means that GPIO access may sleep. This patch makes
      leds-ns2 compatible with such GPIOs by using the *_cansleep() variant of
      the GPIO functions. As a drawback this functions can't be used safely in
      a timer context (with the timer LED trigger for example). To fix this
      issue, a workqueue mechanism (copied from the leds-gpio driver) is used.

      Note that this patch also updates slightly the ns2_led_sata_store
      function. The LED state is now retrieved from cached values instead of
      reading the GPIOs previously. This prevents ns2_led_sata_store from
      working with a stale LED state (which may happen when a delayed work
      is pending).

      leds: leds-ns2: move LED modes mapping outside of the driver

      On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO
      values to LED mode) is different from the one used on other boards
      supported by the leds-ns2 driver.

      With this patch the hardcoded mapping is removed from leds-ns2. Now,
      it must be defined either in the platform data (if an old-fashion board
      setup file is used) or in the DT node. In order to allow the later, this
      patch also introduces a modes-map property for the leds-ns2 DT binding.

      MIPS: CPS: use 32b accesses to GCRs

      Commit b677bc03d757 ("MIPS: cps-vec: Use macros for various arithmetics
      and memory operations") replaced various load & store instructions
      through cps-vec.S with the PTR_L & PTR_S macros. However it was somewhat
      overzealous in doing so for CM GCR accesses, since the bit width of the
      CM doesn't necessarily match that of the CPU. The registers accessed
      (GCR_CL_COHERENCE & GCR_CL_ID) should be safe to simply always access
      using 32b instructions, so do so in order to avoid issues when using a
      32b CM with a 64b CPU.

      x86/mm/mtrr: Remove kernel internal MTRR interfaces: unexport mtrr_add() 
and mtrr_del()

      The effort to replace mtrr_add() with architecture agnostic
      arch_phys_wc_add() is complete, this will ensure write-combining
      implementations (PAT on x86) is taken advantage instead of using
      MTRR. With the effort done now, hide direct MTRR access for
      drivers.

      The legacy user-space /proc/mtrr ABI is not affected.

      Update x86 documentation on MTRR to reflect the completion of
      the phasing out of direct access to MTRR, also add a note on
      platform firmware code use of MTRRs based on the obituary
      discussion of MTRRs on Linux [0].

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Add support for using several Intel PT features (CYC, MTC packets), 
the
          relevant documentation was updated: 
tools/perf/Documentation/intel-pt.txt,
          briefly describing those packets, its purposes, how to configure them 
in
          the event config terms and relevant external documentation for further
          reading. (Adrian Hunter)

        - Introduce support for probing at an absolute address, for user and 
kernel
          'perf probe's, useful when one have the symbol maps on a developer 
machine
          but not on an embedded system. (Wang Nan)

        - Fix 'perf probe' list results when a symbol can't be found or the
          address is zero and when an offset is provided without a function 
(Wang Nan)

        - Do not print '0x (null)' in uprobes when offset is zero (Wang Nan)

        - Clear the progress bar at the end of a ordered_events flush, fixing
          an UI artifact when, after ordering the events the screen doesn't get
          completely redraw, for instance, when an error window covers just the
          center of the screen and waits for user input. (Arnaldo Carvalho de 
Melo)

        - Fix 'annotate' segfault by resetting the dso find_symbol cache when 
removing
          symbols. (Arnaldo Carvalho de Melo)

      Infrastructure changes:

        - Allow duplicate objects in the object list, just like it is possible 
to have
          things like this, in the kernel:

            drivers/Makefile:obj-$(CONFIG_PCI)        += usb/
            drivers/Makefile:obj-$(CONFIG_USB_GADGET) += usb/

          (Jiri Olsa)

        - Fix Intel PT 'instructions' sample period. (Adrian Hunter)

        - Prevent segfault when reading probe point with absolute address. 
(Wang Nan)

      Build fixes:

        - Fix tarball build broken by pt/bts. (Adrian Hunter)

        - Remove export.h from MANIFEST, fixing the perf tarball make target.

      s390/io: Add pci_iomap_wc() and pci_iomap_wc_range()

      The following commit:

        1b3d4200c1e0 ("PCI: Add pci_iomap_wc() variants")

      Introduced pci_iomap_wc() variants but broke the s390 build,
      because s390 requires its own implementation of pcio_iomap*()
      calls.

      The reason for that is that:

        "BAR spaces are not disjunctive on s390 so we need the bar
         parameter of pci_iomap to find the corresponding device
         and create the mapping cookie"

      so it has its own lookup/lock solution and it does not include
      asm-generic/pci_iomap.h.

      Since it currenty maps ioremap_wc() to ioremap_nocache() and
      that's the architecture default we can easily just map the wc
      calls to the default calls as well.

      xfs: add mssing inode cache attempts counter increment

      Increasing the inode cache attempt counter was apparently dropped while
      refactoring the cache code and so stayed at the initial 0 value. Add the
      increment back to make the runtime stats more useful.

      xfs: return errors from partial I/O failures to files

      There is an issue with xfs's error reporting in some cases of I/O 
partially
      failing and partially succeeding. Calls like fsync() can report success 
even
      though not all I/O was successful in partial-failure cases such as one 
disk of
      a RAID0 array being offline.

      The issue can occur when there are more than one bio per xfs_ioend struct.
      Each call to xfs_end_bio() for a bio completing will write a value to
      ioend->io_error.  If a successful bio completes after any failed bio, no
      error is reported do to it writing 0 over the error code set by any 
failed bio.
      The I/O error information is now lost and when the ioend is completed
      only success is reported back up the filesystem stack.

      xfs_end_bio() should only set ioend->io_error in the case of BIO_UPTODATE
      being clear.  ioend->io_error is initialized to 0 at allocation so only 
needs
      to be updated by a failed bio. Also check that ioend->io_error is 0 so 
that
      the first error reported will be the error code returned.

      libxfs: bad magic number should set da block buffer error

      If xfs_da3_node_read_verify() doesn't recognize the magic number of a
      buffer it's just read, set the buffer error to -EFSCORRUPTED so that
      the error can be sent up to userspace.  Without this patch we'll
      notice the bad magic eventually while trying to traverse or change
      the block, but we really ought to fail early in the verifier.

      powerpc/eeh: Fix fenced PHB caused by eeh_slot_error_detail()

      The config space of some PCI devices can't be accessed when their
      PEs are in frozen state. Otherwise, fenced PHB might be seen.
      Those PEs are identified with flag EEH_PE_CFG_RESTRICTED, meaing
      EEH_PE_CFG_BLOCKED is set automatically when the PE is put to
      frozen state (EEH_PE_ISOLATED). eeh_slot_error_detail() restores
      PCI device BARs with eeh_pe_restore_bars(), which then calls
      eeh_ops->restore_config() to reinitialize the PCI device in
      (OPAL) firmware. eeh_ops->restore_config() produces PCI config
      access that causes fenced PHB. The problem was reported on below
      adapter:

         0001:01:00.0 0200: 14e4:168e (rev 10)
         0001:01:00.0 Ethernet controller: Broadcom Corporation \
                      NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)

      This fixes the issue by skipping eeh_pe_restore_bars() in
      eeh_slot_error_detail() when EEH_PE_CFG_BLOCKED is set for the PE.

      Merge branch 'linux-4.3' of 
git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next

      Rather large pull request this time around, due to the long-pending
      cleanup of the kernel driver being here.  There's a stupidly large
      number of commits for that, as I wanted to have the series be
      bisectable at a fairly fine-grained level.  That said, a very large
      portion of the churn in the rework was automated, and a very large
      number of boards from right across the whole range we support have
      been tested.  I'm fairly confident there shouldn't be (too many)
      issues from this.

      Beyond correcting some not-so-great design decisions and making the
      code a lot easier to work with, there's not much exciting (lower
      memory usage, GPU VM should be a lot faster, etc) to be gained by the
      end-user as a result of the cleanup, it mostly lays the groundwork for
      future improvements.

      A big thanks goes to Alexandre Courbot for testing/debugging the GK20A
      codepaths for me :)

      Highlights:
      - A heap of perfmon work, providing a more useful userspace interface
      and specifying counters for a bunch of boards
      - Support for GT200 reclocking + other misc pm improvements
      - Initial patches towards supporting GM20B (Tegra X1)
      - Maxwell DisplayPort fixes
      - Cleanup of the kernel driver
      - The usual collection of random fixes

      drm/nouveau/mmu: protect each vm with its own mutex

      An upcoming commit requires being able to modify the PRAMIN BAR page
      tables while already holding the MMU subdev mutex.

      To solve this issue, each VM has been given its own mutex.  As a nice
      side-effect, this also allows separate VMs to be updated concurrently.

      drm/nouveau/nvif: simplify and tidy library interfaces

      A variety of tweaks to the NVIF library interfaces, mostly ripping out
      things that turned out to be not so useful.

      - Removed refcounting from nvif_object, callers are expected to not be
        stupid instead.
      - nvif_client is directly reachable from anything derived from 
nvif_object,
        removing the need for heuristics to locate it
      - _new() versions of interfaces, that allocate memory for the object
        they construct, have been removed.  The vast majority of callers used
        the embedded _init() interfaces.
      - No longer storing constructor arguments (and the data returned from
        nvkm) inside nvif_object, it's more or less unused and just wastes
        memory.

      drm/nouveau/device: simplify subdev construction

      Replaces the piece-by-piece (in response to NV_DEVICE ctor args) device
      contruction with a once-off all-or-nothing approach, eliminating some
      tricky refcounting issues.  The partial device init capability was only
      required by some tools, and has been moved to probe time instead.

      Temporarily removes a workaround for some boards where we need to fiddle
      with AGP registers before executing the DEVINIT scripts.  A later commit
      in this series reinstates it.

      drm/nouveau/gpuobj: type-safe accessor macros

      These require an explicit struct nvkm_gpuobj pointer, unlike the previous
      macros which take a void *, and work with any nvkm_object.

      New semantics require acquiring/releasing a gpuobj before accessing them,
      which will be made use of in later patches to greatly reduce the overhead
      of accesses, particularly when a direct mmio mapping of the object is not
      available (suspend/resume, out of ioremap() space, and on GK20A).

      drm/nouveau/core: type-safe printk macros

      These require an explicit pointers to nvkm_object/nvkm_subdev/nvkm_device,
      depending on which macros are used.  This is unlike the previous macros
      which take a void *, and work for anything derived from nvkm_object (by
      way of some awful heuristics).

      The output will be a bit confused until everything has been transitioned,
      as the logging format used is a more standard style that previously.

      In addition, usage of pr_cont(), which doesn't work correctly with the
      dev_*() printk functions (and was potentially racy to begin with), will
      be replaced.

      drm/nouveau/tmr: type-safe PTIMER-based delay/wait macros

      These require an explicit struct nvkm_device pointer, unlike the previous
      macros which take a void *, and work for (almost) anything derived from
      nvkm_object by using some heuristics.

      These macros are more general than the previous ones, and can be used to
      handle PTIMER-based busy-waits (will be used in later devinit fixes) as
      well as more complicated wait conditions.

      drm/nouveau/device: type-safe register accessor macros

      These require an explit struct nvkm_device pointer, unlike the previous
      macros which take a void *, and assume it's any old nvkm_subdev.

      drm/nouveau/device: include core/device.h automatically for 
subdevs/engines

      Pretty much every subdev/engine is going to need access to nvkm_device
      shortly to touch registers and/or output messages.

      The odd placement of the includes is necessary to work around some
      inter-dependencies that currently exist.  This will be fixed later.

      drm/nouveau/pm: allow to configure domains instead of simple counters

      Configuring counters from the userspace require the kernel to handle some
      logic related to performance counters. Basically, it has to find a free
      slot to assign a counter, to handle extra counting modes like B4/B6 and it
      must return and error when it can't configure a counter.

      In my opinion, the kernel should not handle all of that logic but it
      should only write the configuration sent by the userspace without
      checking anything. In other words, it should overwrite the configuration
      even if it's already counting and do not return any errors.

      This patch allows the userspace to configure a domain instead of
      separate counters. This has the advantage to move all of the logic to
      the userspace.

      powerpc/pseries: Fix corrupted pdn list

      Commit cca87d30 ("powerpc/pci: Refactor pci_dn") introduced pdn
      list for SRIOV VFs. It means the pdn is be put into the child list
      of its parent pdn when the pdn is created. When doing PCI hot
      unplugging on pSeries, the PCI device node as well as its pdn are
      released through procfs entry "powerpc/ofdt". Some one else grabs
      the memory chunk of the pdn and update it accordingly. At the same
      time, the pdn is still tracked in the child list of parent pdn. It
      leads to corrupted child list in the parent pdn.

      This fixes above issue by removing the pdn from the child list of
      its parent pdn when the device node is detached from the system.
      Note the pdn is free'd when the device node is released if the
      device node is dynamic one. Otherwise, the device node as well
      as the pdn won't be released.

       "This is a libnvdimm ABI fixup.

        I pushed back on this change quite hard given the late date, that it
        appears to be purely cosmetic, sysfs is not necessarily meant to be a
        user friendly UI, and the kernel interprets the reversed polarity of
        the ACPI_NFIT_MEM_ARMED flag correctly.  When this flag is set, the
        energy source of an NVDIMM is not armed and any new writes to the DIMM
        may not be preserved.

        However, Bob Moore warned me that it is important to get these things
        named correctly wherever they appear otherwise we run the risk of a
        less than cautious firmware engineer implementing the polarity the
        wrong way.  Once a mistake like that escapes into production platforms
        the flag becomes useless and we need to move to a new bit position.

        Bob has agreed to take a change through ACPICA to rename
        ACPI_NFIT_MEM_ARMED to ACPI_NFIT_MEM_NOT_ARMED, and the patch below
        from Toshi brings the sysfs representation of these flags in line with
        their respective polarities.

        Please pull for 4.2 as this is the first kernel to expose the ACPI
        NFIT sysfs representation, and this is likely a kernel that firmware
        developers will be using for checking out their NVDIMM enabling"

      Phil Sutter says:

      ====================
      fixup IFF_NO_QUEUE conversion

      This series serves two purposes:

      On one hand it fixes a quite embarrassing bug around the warning I added 
for
      drivers still setting tx_queue_len = 0 to achieve noqueue operation. It 
turned
      out to be quite useless as due to using alloc_netdev(), many in-kernel 
drivers
      fell into the trap by accident, as well. Instead this place serves pretty 
well
      as a sanitizing point to set IFF_NO_QUEUE for drivers not initializing
      tx_queue_len, which in turn allows to drop all special treatment of the 
latter
      being zero since that can not happen anymore without IFF_NO_QUEUE being 
set.

      On the other hand, it provides a better solution for Eric Dumazet's 
concern
      regarding how to assign noqueue to an interface which does not default to 
it
      already. In order to make this possible, noqueue is being registered so 
users
      can 'tc qd add dev eth0 root noqueue'. In addition, it resolves the ugly
      situation of 'tc qd show' not showing noqueue. Finally, the former changes
      allow for some code cleanup.

      tx_queue_len is zero and set IFF_NO_QUEUE, so the value of tx_queue_len

      sctp: donot reset the overall_error_count in SHUTDOWN_RECEIVE state

      Commit f8d960524328 ("sctp: Enforce retransmission limit during shutdown")
      fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by 
not
      resetting the association overall_error_count.  This allowed the 
association
      to better enforce assoc.max_retrans limit.

      However, the same issue still exists when the association is in 
SHUTDOWN_RECEIVED
      state.  In this state, HB-ACKs will continue to reset the 
overall_error_count
      for the association would extend the lifetime of association 
unnecessarily.

      This patch solves this by resetting the overall_error_count whenever the 
current
      state is small then SCTP_STATE_SHUTDOWN_PENDING.  As a small side-effect, 
we
      end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and 
SCTP_STATE_SHUTDOWN_SENT
      states, but they are not really impacted because we disable Heartbeats in 
those
      states.

      x86, pmem: clarify that ARCH_HAS_PMEM_API implies PMEM mapped WB

      Given that a write-back (WB) mapping plus non-temporal stores is
      expected to be the most efficient way to access PMEM, update the
      definition of ARCH_HAS_PMEM_API to imply arch support for
      WB-mapped-PMEM.  This is needed as a pre-requisite for adding PMEM to
      the direct map and mapping it with struct page.

      The above clarification for X86_64 means that memcpy_to_pmem() is
      permitted to use the non-temporal arch_memcpy_to_pmem() rather than
      needlessly fall back to default_memcpy_to_pmem() when the pcommit
      instruction is not available.  When arch_memcpy_to_pmem() is not
      guaranteed to flush writes out of cache, i.e. on older X86_32
      implementations where non-temporal stores may just dirty cache,
      ARCH_HAS_PMEM_API is simply disabled.

      The default fall back for persistent memory handling remains.  Namely,
      map it with the WT (write-through) cache-type and hope for the best.

      arch_has_pmem_api() is updated to only indicate whether the arch
      provides the proper helpers to meet the minimum "writes are visible
      outside the cache hierarchy after memcpy_to_pmem() + wmb_pmem()".  Code
      that cares whether wmb_pmem() actually flushes writes to pmem must now
      call arch_has_wmb_pmem() directly.

      mm: ZONE_DEVICE for "device memory"

      While pmem is usable as a block device or via DAX mappings to userspace
      there are several usage scenarios that can not target pmem due to its
      lack of struct page coverage. In preparation for "hot plugging" pmem
      into the vmemmap add ZONE_DEVICE as a new zone to tag these pages
      separately from the ones that are subject to standard page allocations.
      Importantly "device memory" can be removed at will by userspace
      unbinding the driver of the device.

      Having a separate zone prevents allocation and otherwise marks these
      pages that are distinct from typical uniform memory.  Device memory has
      different lifetime and performance characteristics than RAM.  However,
      since we have run out of ZONES_SHIFT bits this functionality currently
      depends on sacrificing ZONE_DMA.

      bridge: fdb: rearrange net_bridge_fdb_entry

      While looking into fixing the local entries scalability issue I noticed
      that the structure is badly arranged because vlan_id would fall in a
      second cache line while keeping rcu which is used only when deleting
      in the first, so re-arrange the structure and push rcu to the end so we
      can get 16 bytes which can be used for other fields (by pushing rcu
      fully in the second 64 byte chunk). With this change all the core
      necessary information when doing fdb lookups will be available in a
      single cache line.

      nd_blk: change aperture mapping from WC to WB

      This should result in a pretty sizeable performance gain for reads.  For
      rough comparison I did some simple read testing using PMEM to compare
      reads of write combining (WC) mappings vs write-back (WB).  This was
      done on a random lab machine.

      PMEM reads from a write combining mapping:
        # dd of=/dev/null if=/dev/pmem0 bs=4096 count=100000
        100000+0 records in
        100000+0 records out
        409600000 bytes (410 MB) copied, 9.2855 s, 44.1 MB/s

      PMEM reads from a write-back mapping:
        # dd of=/dev/null if=/dev/pmem0 bs=4096 count=1000000
        1000000+0 records in
        1000000+0 records out
        4096000000 bytes (4.1 GB) copied, 3.44034 s, 1.2 GB/s

      To be able to safely support a write-back aperture I needed to add
      support for the "read flush" _DSM flag, as outlined in the DSM spec:

      http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf

      This flag tells the ND BLK driver that it needs to flush the cache lines
      associated with the aperture after the aperture is moved but before any
      new data is read.  This ensures that any stale cache lines from the
      previous contents of the aperture will be discarded from the processor
      cache, and the new data will be read properly from the DIMM.  We know
      that the cache lines are clean and will be discarded without any
      writeback because either a) the previous aperture operation was a read,
      and we never modified the contents of the aperture, or b) the previous
      aperture operation was a write and we must have written back the dirtied
      contents of the aperture to the DIMM before the I/O was completed.

      In order to add support for the "read flush" flag I needed to add a
      generic routine to invalidate cache lines, mmio_flush_range().  This is
      protected by the ARCH_HAS_MMIO_FLUSH Kconfig variable, and is currently
      only supported on x86.

      mlxsw: Make mailboxes 4KB aligned

      The HW-SW contract requires mailboxes passed to the firmware to be 4KB
      aligned. Previously, these mailboxes were mapped using streaming DMA
      routines, which do not guarantee the bus addresses to be 4KB aligned.
      Under certain conditions this constraint was indeed violated and errors
      were observed.

      By using consistent DMA mapping routines together with a mailbox size of
      4KB we are guaranteed not to violate the constraint.

      mtd: mtd_oobtest: Fix the address offset with vary_offset case

      When vary_offset is set (e.g. test case 3), the offset is not always
      zero so memcmpshow() will show the wrong offset in the print message.
      To fix this we introduce a new function memcmpshowoffset() which takes
      offset as a parameter and displays the right offset and use it in
      the case where offset is non zero.

      The old memcmpshow() functionality is preserved by converting it into
      a macro with offset preset to 0.

      - for small receive buffer, it will also be 2.

      Geneve: Add support for tunnel metadata mode

      Following patches adds support for Geneve tunnel metadata
      mode. OVS can make use of Geneve net-device with tunnel
      metadata API from kernel.

      This also allows us to consolidate Geneve implementation
      from two kernel modules geneve_core and geneve to single
      geneve module. geneve_core module was targeted to share
      Geneve encap and decap code between Geneve netdevice and
      OVS Geneve tunnel implementation, Since OVS no longer
      needs these API, Geneve code can be consolidated into
      single geneve module.

      v3-v4:
      - Drop NETIF_F_NETNS_LOCAL feature.
      - Fix geneve device newlink check

      v2-v3:
      - make tunnel medata device and regular device mutually exclusive.
      - Fix Kconfig dependency for Geneve.
      - Fix dst-port netlink encoding.
      - drop changelink patch.

      v1-v2:
      - Replaced per hash table tunnel pointer (metadata enabled) with flag.
      - Added support for changelink.
      - Improve geneve device route lookup with more parameters.

      selftests/zram: Adding zram tests

      zram: Compressed RAM based block devices
      ----------------------------------------
      The zram module creates RAM based block devices named /dev/zram<id>
      (<id> = 0, 1, ...). Pages written to these disks are compressed and stored
      in memory itself. These disks allow very fast I/O and compression provides
      good amounts of memory savings. Some of the usecases include /tmp storage,
      use as swap disks, various caches under /var and maybe many more :)

      Statistics for individual zram devices are exported through sysfs nodes at
      /sys/block/zram<id>/

      This patch is to validate the zram functionality. Test interacts with 
block
      device /dev/zram<id> and sysfs nodes /sys/block/zram<id>/

      Documentation/Changes: Now need OpenSSL devel packages for module signing

      The module signing script (sign-file) used to be a wrapper around the
      openssl program.  It has now been replaced by a C program that uses the
      crypto library from the OpenSSL package meaning that the OpenSSL devel
      packages are necessary to provide the devel library link and the header
      files.

      This would be openssl-devel on Fedora and libssl-dev on Debian.

      smsc911x: Ignore error return from device_get_phy_mode()

      Commit 62ee783bf1f8 ("smsc911x: Fix crash seen if neither ACPI nor OF is
      configured or used") introduces an error check for the return value from
      device_get_phy_mode() and bails out if there is an error. Unfortunately,
      there are configurations where no phy is configured. Those configurations
      now fail.

      To fix the problem, accept error returns from device_get_phy_mode(),
      and use the return value from device_property_read_u32() to determine
      if there is a suitable firmware interface to read the configuration.

      net: sched: consolidate tc_classify{,_compat}

      For classifiers getting invoked via tc_classify(), we always need an
      extra function call into tc_classify_compat(), as both are being
      exported as symbols and tc_classify() itself doesn't do much except
      handling of reclassifications when tp->classify() returned with
      TC_ACT_RECLASSIFY.

      CBQ and ATM are the only qdiscs that directly call into 
tc_classify_compat(),
      all others use tc_classify(). When tc actions are being configured
      out in the kernel, tc_classify() effectively does nothing besides
      delegating.

      We could spare this layer and consolidate both functions. pktgen on
      single CPU constantly pushing skbs directly into the netif_receive_skb()
      path with a dummy classifier on ingress qdisc attached, improves
      slightly from 22.3Mpps to 23.1Mpps.

      Intel Wired LAN Driver Updates 2015-08-26

      This series contains updates to i40e and i40evf only.

      Anjali provides a fix for i40e where the part is not receiving multicast
      or VLAN tagged packets when in promiscuous mode.  This can occur when a
      software bridge is created on top of the device.  Fixed the legacy and MSI
      interrupt mode in the driver, which was non-existent before since we
      were assuming MSIX was the only mode that the driver ran in.  Fixed the
      i40evf driver, where the wrong defines were getting used in the VF
      driver.

      Mitch fixes a sparse warning about comparing __le16 to u16 so use
      le16_to_cpu() to resolve the warning.  Also fixed a dyslexic spelling
      of invalid.

      Shannon adds port.crc_errors to receive CRC error counter, since it
      is a receive counter.

      Catherine provides a fix to move the stopping of the service task and
      flow director to i40e_shutdown() instead of i40e_suspend().

      Greg fixes the ethtool offline diagnostic with netqueues, which just need
      to be treated the same as virtual functions when someone wants to run the
      ethtool offline diagnostic test.  Also fixed up code comments for the
      i40e ethtool diagnostic test function.  Cleans up redundant and unneeded
      messages, since the kernel notifies all VXLAN capable registered drivers,
      so no need to log this.

      Neerav adds the ability to update statistics per VEB per traffic class
      and dump it via ethtool.

      Jingjing adds support for virtual channel offload to support receive
      polling mode in the VF driver.

      v2: dropped patch which added helper functions into a header, feedback 
from
          David Miller was to make the functions constant to reduce the driver
          footprint, so remove the patch while Anjali works on making the 
requested
          changes.

      sctp: asconf's process should verify address parameter is in the beginning

      in sctp_process_asconf(), we get address parameter from the beginning of
      the addip params. but we never check if it's really there. if the addr
      param is not there, it still can pass sctp_verify_asconf(), then to be
      handled by sctp_process_asconf(), it will not be safe.

      so add a code in sctp_verify_asconf() to check the address parameter is in
      the beginning, or return false to send abort.

      note that this can also detect multiple address parameters, and reject it.

      CONFIG_OPENVSWITCH_CONNTRACK or disabling individual conntrack features 
like

      openvswitch: Allow attaching helpers to ct action

      Add support for using conntrack helpers to assist protocol detection.
      The new OVS_CT_ATTR_HELPER attribute of the CT action specifies a helper
      to be used for this connection. If no helper is specified, then helpers
      will be automatically applied as per the sysctl configuration of
      net.netfilter.nf_conntrack_helper.

      The helper may be specified as part of the conntrack action, eg:
      ct(helper=ftp). Initial packets for related connections should be
      committed to allow later packets for the flow to be considered
      established.

      Example ovs-ofctl flows allowing FTP connections from ports 1->2:
      in_port=1,tcp,action=ct(helper=ftp,commit),2
      in_port=2,tcp,ct_state=-trk,action=ct(recirc)

      openvswitch: Add conntrack action

      Expose the kernel connection tracker via OVS. Userspace components can
      make use of the CT action to populate the connection state (ct_state)
      field for a flow. This state can be subsequently matched.

      Exposed connection states are OVS_CS_F_*:
      - NEW (0x01) - Beginning of a new connection.
      - ESTABLISHED (0x02) - Part of an existing connection.
      - RELATED (0x04) - Related to an established connection.
      - INVALID (0x20) - Could not track the connection for this packet.
      - REPLY_DIR (0x40) - This packet is in the reply direction for the flow.
      - TRACKED (0x80) - This packet has been sent through conntrack.

      When the CT action is executed by itself, it will send the packet
      through the connection tracker and populate the ct_state field with one
      or more of the connection state flags above. The CT action will always
      set the TRACKED bit.

      When the COMMIT flag is passed to the conntrack action, this specifies
      that information about the connection should be stored. This allows
      subsequent packets for the same (or related) connections to be
      correlated with this connection. Sending subsequent packets for the
      connection through conntrack allows the connection tracker to consider
      the packets as ESTABLISHED, RELATED, and/or REPLY_DIR.

      The CT action may optionally take a zone to track the flow within. This
      allows connections with the same 5-tuple to be kept logically separate
      from connections in other zones. If the zone is specified, then the
      "ct_zone" match field will be subsequently populated with the zone id.

      IP fragments are handled by transparently assembling them as part of the
      CT action. The maximum received unit (MRU) size is tracked so that
      refragmentation can occur during output.

      IP frag handling contributed by Andy Zhou.

      Based on original design by Justin Pettit.

      openvswitch: Serialize acts with original netlink len

      Previously, we used the kernel-internal netlink actions length to
      calculate the size of messages to serialize back to userspace.
      However,the sw_flow_actions may not be formatted exactly the same as the
      actions on the wire, so store the original actions length when
      de-serializing and re-use the original length when serializing.

      nfit: Clarify memory device state flags strings

      ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines
      NVDIMM status as follows.  These bits indicate multiple info,
      such as failures, pending event, and capability.

        Bit [0] set to 1 to indicate that the previous SAVE to the
        Memory Device failed.
        Bit [1] set to 1 to indicate that the last RESTORE from the
        Memory Device failed.
        Bit [2] set to 1 to indicate that platform flush of data to
        Memory Device failed. As a result, the restored data content
        may be inconsistent even if SAVE and RESTORE do not indicate
        failure.
        Bit [3] set to 1 to indicate that the Memory Device is observed
        to be not armed prior to OSPM hand off. A Memory Device is
        considered armed if it is able to accept persistent writes.
        Bit [4] set to 1 to indicate that the Memory Device observed
        SMART and health events prior to OSPM handoff.

      /sys/bus/nd/devices/nmemX/nfit/flags shows this flags info.
      The output strings associated with the bits are "save", "restore",
      "smart", etc., which can be confusing as they may be interpreted
      as positive status, i.e. save succeeded.

      Change also the dev_info() message in acpi_nfit_register_dimms()
      to be consistent with the sysfs flags strings.

      Broadcom buses may have more than 1 Ethernet device. This is used e.g.
      to have few interfaces connected to different switch ports. So far we

      batman-adv: don't access unregistered net_device object

      In batadv_hardif_disable_interface() there is a call to
      batadv_softif_destroy_sysfs() which in turns invokes
      unregister_netdevice() on the soft_iface.
      After this point we cannot rely on the soft_iface object
      anymore because it might get free'd by the netdev periodic
      routine at any time.

      For this reason the netdev_upper_dev_unlink(.., soft_iface) call
      is moved before the invocation of batadv_softif_destroy_sysfs() so
      that we can be sure that the soft_iface object is still valid.

      mpt3sas: When device is blocked followed by unblock fails, unfreeze the 
I/Os

      Issue: When the disks are getting discovered and assigned device
      handles by the kernel, a device block followed by an unblock
      (due to broadcast primitives) issued by the driver is
      interspersed by the kernel changing the state of the device.
      Therefore the unblock by the driver results in a no operation
      within the kernel API.

      To fix this one, the below patch checks the return of the unblock API
      and performs a block followed by an unblock to unfreeze the block
      layer's I/O queue. Sufficient checks and prints are also added in the
      driver to identify this condition caused by the kernel.

Layer(SML),

      For any SCSI command, if the driver receives
      IOC status = SCSI_IOC_TERMINATED and log info = 0x32010081 then
      that command will be completed with DID_RESET host status.

      The definition of this log info value is
      "Virtual IO has failed and has to be retried".

      Firmware will provide this log info value with IOC Status
      "SCSI_IOC_TERMINATED", whenever a drive (with is a part of a volume)
      is pulled and pushed back within some minimal delay.
      With this log info value, firmware informs the driver to retry the
      failed IO command infinite times, so to provide some time for the
      firmware to discover the reinserted drive successfully instated of
      just retrying failed command for five times(doesn't giving enough
      time for firmware to complete the drive discovery) and failing the
      IO permanently even though drive came back successfully.

      This Patch will provide more details of the devices such as slot number,
      enclosure logical id, enclosure level & connector name in the following
      scenarios,

      - When end device is added in the topology,

      - When the end device is removed from the setup,

      - When the SCSI mid layer issues TASK ABORT/ DEVICE RESET/ TARGET RESET 
during
        error handling,

      - When any command to the device fails with Sense key Hardware error or 
Medium
        error or Unit Attention,

      - When firmware returns device error or device not ready status for the 
end
        device,

      - When a Predicted fault is detected on an end device.

      This information can be used by the user to identify the location of the
      desired drive in the topology.

      Driver will get these information by reading the sas device page0.

      mpt3sas: Don't block the drive when drive addition under the control of 
SML

      During hot-plugging of a disk(having a flaky link), the disk addition
      stops and any further disk addition or removal doesn't happen on that
      controller.

      This is because, when driver receives DELAY_NOT_RESPONDING event for a 
disk
      while it is undergoing addition at the SCSI Transport layer, the driver
      would block the I/O to that disk resulting in a deadlock. i.e the disk
      addition work couldn't be completed at the SCSI Transport Layer as it
      can't send any I/Os (such as Inquiry, Report LUNs etc) to the disk as
      I/Os are blocked to this drive. Also any subsequent device removal
      (TARGET_NOT_RESPONDING) or link update(RC_PHY_CHANGED) event couldn't be
      processed as they are in the queue to get processed after disk addition
      event.

      Description of Change:
      Don't block the drive when drive addition is under the control of SML.
      So that SML won't be blocked of issuing the device dicovery commands
      (such as Inquiry, Report LUNs etc).

      mpt3sas: Added Combined Reply Queue feature to extend up-to 96 MSIX 
vector support

      In this patch, increased the number of MSIX vector support for SAS3 C0 
HBAs to
      up-to 96.

      Following are changes that are done in this patch

      1. This feature is enabled only for SAS3 C0 and higher revision cards and 
also
      only when reply post free queue count is greater than 8.

      2. To support this feature 12 SupplementalReplyPostHostIndex system 
interfaces
      are used. MSI-X index numbered from 0 to 7 use the first
      SupplementalReplyPostHostIndex system interface to update its 
corresponding
      ReplyPostHostIndex values, MSI-X index numbered from 8 to 15 will use the
      second SupplementalReplyPostHostIndex system interface and so on. These 12
      SuppementalReplyPostHostIndex system interfaces address are saved in the 
array
      replyPostRegisterIndex[].

      3. As each SupplementalReplyPostHostIndex register supports 8 MSI-X
      vectors. So MSIxIndex field in these register must contain a value 
between 0
      and 7.

      4. After processing the reply descriptors from a reply post free queues 
then
      update the new reply post host index value in ReplyPostHostIndex field and
      (msix_index mod 8) value in MSIxIndex field of 
SupplementalReplyPostHostIndex
      register. The Address of this SupplementalReplyPostHostIndex register is
      retrived from (msix_index/8)th entry of replyPostRegisterIndex[] array.

      arm64: KVM: Fix host crash when injecting a fault into a 32bit guest

      When injecting a fault into a misbehaving 32bit guest, it seems
      rather idiotic to also inject a 64bit fault that is only going
      to corrupt the guest state. This leads to a situation where we
      perform an illegal exception return at EL2 causing the host
      to crash instead of killing the guest.

      Just fix the stupid bug that has been there from day 1.

      irqchip/GIC: Convert to EOImode == 1

      So far, GICv2 has been used with EOImode == 0. The effect of this
      mode is to perform the priority drop and the deactivation of the
      interrupt at the same time.

      While this works perfectly for Linux (we only have a single priority),
      it causes issues when an interrupt is forwarded to a guest, and when
      we want the guest to perform the EOI itself.

      For this case, the GIC architecture provides EOImode == 1, where:
      - A write to the EOI register drops the priority of the interrupt
        and leaves it active. Other interrupts at the same priority level
        can now be taken, but the active interrupt cannot be taken again
      - A write to the DIR marks the interrupt as inactive, meaning it can
        now be taken again.

      We only enable this feature when booted in HYP mode and that
      the device-tree reported a suitable CPU interface. Observable behaviour
      should remain unchanged.

      While this works perfectly for Linux (we only have a single priority),

      - A write to ICC_DIR_EL1 marks the interrupt as inactive, meaning
        it can now be taken again.

      This patch converts the driver to be able to use this new mode,
      depending on whether or not the kernel can behave as a hypervisor.
      No feature change.

      hwmon: (fam15h_power) Add ratio of Tsample to the PTSC period

      This patch adds a member (cpu_pwr_sample_ratio) of fam15h_power_data,
      that represents the ratio of compute unit power accumulator sample
      period to the PTSC counter period.

      Tsample: compute unit power accumulator sample period
      Tref: the performance timestamp counter period
      PTSC: performance timestamp counter

      mmc: sunxi: fix timeout in sunxi_mmc_oclk_onoff

      The 250ms timeout is too short.

      On my system enabling the oclk takes under 50ms and disabling slightly
      over 100ms when idle. Under load disabling the clock can take over
      350ms.

      This does not make mmc clock gating look like good option to have on
      sunxi but the system should not crash with mmc clock gating enabled
      nonetheless.

      This patch sets the timeout to 750ms.

      mmc: sdhci-esdhc-imx: change default watermark level and burst length

      By default, for all imx SoC types, the watermark level is 16, and the
      burst length is 8. But if the SDIO/SD/MMC I/O speed is fast enough,
      this default watermark level and burst length will be the performance
      bottleneck.

      For example, i.MX7D support eMMC HS400 mode, this mode can run in 8 bit,
      200MHZ DDR mode. So the I/O speed improve a lot compare to SD3.0.
      The default burst length is 8, if we don't change this value, in
      HS400 mode, when we do eMMC read operation, we can find that the
      clock signal will stop for a period of time. This means the speed
      of data moving on AHB bus is slower than I/O speed. So we should
      improve the speed of data moving on AHB bus.

      This patch set the default burst length as 16, and set the default
      watermark level as 64. The test result is the clock signal has
      no stop during the eMMC HS400 operation.

      Also note that powernv LEDS driver needs NEW_LEDS and LEDS_CLASS

      powerpc/iommu: Set default DMA offset in dma_dev_setup

      Commit e91c25111aa3 "powerpc/iommu: Cleanup setting of DMA base/offset"
      expects that the default DMA offset is set from pnv_ioda_setup_bus_dma()
      which is correct unless it is SRIOV where the code flow is different -
      at the moment when pnv_ioda_setup_bus_dma() is called, PCI devices for
      VFs are not created yet.

      This adds missing set_dma_offset() to pnv_pci_ioda_dma_dev_setup() to
      cover the case of SRIOV.

      Note that we still need set_dma_offset() in pnv_ioda_setup_bus_dma() as
      at the boot time pnv_pci_ioda_dma_dev_setup() is called when no PE was
      created yet, this happens at the PHB fixup stage.

      ARCv2: perf: Support sampling events using overflow interrupts

      In times of ARC 700 performance counters didn't have support of
      interrupt an so for ARC we only had support of non-sampling events.

      Put simply only "perf stat" was functional.

      Now with ARC HS we have support of interrupts in performance counters
      which this change introduces support of.

      ARC performance counters act in the following way in regard of
      interrupts generation.
       [1] A counter counts starting from value set in PCT_COUNT register pair
       [2] Once counter reaches value set in PCT_INT_CNT interrupt is raised

      Basic setup look like this:
       [1] PCT_COUNT = 0;
       [2] PCT_INT_CNT = __limit_value__;
       [3] Enable interrupts for that counter and let it run
       [4] Let counter reach its limit
       [5] Handle interrupt when it happens

      Note that PCT HW block is build in CPU core and so ints interrupt
      line (which is basically OR of all counters IRQs) is wired directly to
      top-level IRQC. That means do de-assert PCT interrupt it's required to
      reset IRQs from all counters that have reached their limit values.

      ARCv2: perf: implement "event_set_period"

      This generalization prepares for support of overflow interrupts.

      Hardware event counters on ARC work that way:
      Each counter counts from programmed start value (set in
      ARC_REG_PCT_COUNT) to a limit value (set in ARC_REG_PCT_INT_CNT) and
      once limit value is reached this timer generates an interrupt.

      Even though this hardware implementation allows for more flexibility,
      in Linux kernel we decided to mimic behavior of other architectures
      this way:

       [1] Set limit value as half of counter's max value (to allow counter to
           run after reaching it limit, see below for more explanation):
       ---------->8-----------
       arc_pmu->max_period = (1ULL << counter_size) / 2 - 1ULL;
       ---------->8-----------

       [2] Set start value as "arc_pmu->max_period - sample_period" and then
      count up to the limit

      Our event counters don't stop on reaching max value (the one we set in
      ARC_REG_PCT_INT_CNT) but continue to count until kernel explicitly
      stops each of them.

      And setting a limit as half of counter capacity is done to allow
      capturing of additional events in between moment when interrupt was
      triggered until we're actually processing PMU interrupts. That way
      we're trying to be more precise.

      For example if we count CPU cycles we keep track of cycles while
      running through generic IRQ handling code:

       [1] We set counter period as say 100_000 events of type "crun"
       [2] Counter reaches that limit and raises its interrupt
       [3] Once we get in PMU IRQ handler we read current counter value from
      ARC_REG_PCT_SNAP ans see there something like 105_000.

      If counters stop on reaching a limit value then we would miss
      additional 5000 cycles.

      arm64: flush FP/SIMD state correctly after execve()

      When a task calls execve(), its FP/SIMD state is flushed so that
      none of the original program state is observeable by the incoming
      program.

      However, since this flushing consists of setting the in-memory copy
      of the FP/SIMD state to all zeroes, the CPU field is set to CPU 0 as
      well, which indicates to the lazy FP/SIMD preserve/restore code that
      the FP/SIMD state does not need to be reread from memory if the task
      is scheduled again on CPU 0 without any other tasks having entered
      userland (or used the FP/SIMD in kernel mode) on the same CPU in the
      mean time. If this happens, the FP/SIMD state of the old program will
      still be present in the registers when the new program starts.

      So set the CPU field to the invalid value of NR_CPUS when performing
      the flush, by calling fpsimd_flush_task_state().

      target/iscsi: Replace conn->login_ip with login_sockaddr

      Very similar to how it went with local_sockaddr.

      It was embedded in iscsi_login_stats so some changes there, and we needed
      to copy in a sockaddr_storage comparison function. Hopefully the kernel
      will get a standard one soon, our implementation makes the 3rd.

      isert_set_conn_info() became much smaller.

      IPV6_ADDRESS_SPACE define goes away, had to modify a call to in6_pton(),
      can just use -1 since we are sure string is null-terminated.

      target/iscsi: Keep local_ip as the actual sockaddr

      This is a more natural format that lets us format it with the appropriate
      printk specifier as needed.

      This also lets us handle v4-mapped ipv6 addresses a little more nicely, by
      storing the addr as an actual v4 sockaddr in conn->local_sockaddr.

      Finally, we no longer need to maintain variables for port, since this is
      contained in sockaddr. Remove iscsi_np.np_port and iscsi_conn.local_port.

      Revert commit 1997e6259, which causes double brackets on ipv6

      Since we have np_sockaddr, if we need a textual representation we can

      cxl: Remove racy attempt to force EEH invocation in reset

      cxl_reset currently PERSTs the slot, and then repeatedly tries to
      read MMIO space in order to kick off EEH.

      There are 2 problems with this: it's unnecessary, and it's racy.

      It's unnecessary because the PERST will bring down the PHB link.
      That will be picked up by the CAPP, which will send out an HMI.
      Skiboot, noticing an HMI from the CAPP, will send an OPAL
      notification to the kernel, which will trigger EEH recovery.

      It's also racy: the EEH recovery triggered by the CAPP will
      eventually cause the MMIO space to have its mapping invalidated
      and the pointer NULLed out. This races with our attempt to read
      the MMIO space. This is causing OOPSes in testing.

      Simply drop all the attempts to force EEH detection, and trust
      that Skiboot will send the notification and that we'll act on it.
      The Skiboot code to send the EEH notification has been in Skiboot
      for as long as CAPP recovery has been supported, so we don't need
      to worry about breaking obscure setups with ancient firmware.

      Merge branch 'drm-dwhdmi-devel' of 
git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next

      Here are some development updates for the Synopsis Designware HDMI driver,
      which clean up some of the code, and start preparing to add audio support
      to the driver.  This series of patches are based on a couple of dependent
      commits from the ALSA tree.

      Briefly, the updates are:
      - move comments which should have moved with the phy values to the IMX
        part of the driver.
      - clean up the phy configuration: to all lookups before starting to
        program the phy.
      - clean up the HDMI clock regenerator code
      - use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
        the code to be subsequently simplified
      - remove the unused 'regmap' pointer in struct dw_hdmi
      - use the bridge drm device rather than the connector (we're the bridge
        code)
      - remove private hsync/vsync/interlaced flags, getting them from the
        DRM mode structure instead.
      - implement interface functions to support audio - setting the audio
        sample rate, and enabling the audio clocks.
      - removal of broken pixel repetition support
      - cleanup DVI vs HDMI sink handling
      - enable audio only if connected device supports audio
      - avoid double-enabling bridge in the sink path (once in mode_set, and
        again in commit)
      - rename mis-named dw_hdmi_phy_enable_power()
      - fix bridge enable/disable handing, so a plug-in event doesn't
        reconfigure the bridge if DRM has disabled the output
      - fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name

      These are primerily preparitory patches for the AHB audio driver and
      the I2S audio driver (from Rockchip) for this IP.

      A device state is added to track 3 possible states of the device:

      Normal - the device is operating normally and is fully operational

      Limbo - the device is in a reset/recovery scenario and its operational
              status is paused

      Failed/terminating - the device has either failed to be reset/recovered
                           or is being terminated (removed); it is no longer
                           operational

      All operations are allowed when the device is operating normally. When the
      device transitions to limbo state, I/O must be paused. To help accomplish
      this, a wait queue is introduced where existing and new threads can wait
      until the device is no longer in limbo. When coming out of limbo, threads
      need to check the state and error out gracefully when encountering the
      failed state. When the device transitions to the failed/terminating state,
      normal operations are no longer allowed. Only specially designated
      operations related to graceful cleanup are permitted.

      scsi_error: should not get sense for timeout IO in scsi error handler

      scsi_error: should not get sense for timeout IO in scsi error handler

      When an IO timeout occurs, the IO will be aborted in
      scsi_abort_command() and SCSI_EH_ABORT_SCHEDULED will be set. Because
      of that, the SCSI_EH_CANCEL_CMD will be clear in scsi_eh_scmd_add().
      So when scsi error handler starts, it will get sense for this
      timeout IO and the scmd of the IO request will be reused. In that
      case, the scmd may be double released when racing with io_done(),
      which will result in crash.
      SO SCSI_EH_ABORT_SCHEDULED should also be checked when getting sense.
      The bug maybe reproduced when the link between host and disk is
      unstable.

      hpsa: fix issues with multilun devices

      A regression was introduced into the hpsa driver a while back so
      non-zero LUNs of multi-LUN devices may no longer be presented via
      a SAS based Smart Array. I have not done a bisection to discover
      the change that caused it.

      The CISS firmware specification (available on sourceforge)
      defines an 8 byte lunid that describes devices that the Smart
      Array can see/present to the system. The current code in the hpsa
      driver attempts to find matches for non-zero LUNs with LUN 0 for
      a bus/target by zeroing out byte 4 of the lunid and find a match.

      This method is sufficient for SCSI based Smart Arrays because
      byte 5 is always 0. For SAS based Smart arrays byte 5 of the
      lunid contains the path number for a multipath device and
      either one or two bits (the documentation does not define how
      many bits are used but it appears it may be one only) that
      indicate if the given path number in byte 5 must always be
      used to access that device. Byte 5 may not always be zero.

      The following are lunids (spaces added for clarity) for a
      MSL2024 single drive library connected via a H241 Smart Array:

      00 00 00 00 01 00 00 01 (changer)
      00 00 00 00 00 80 00 01 (tape)

      In the 4th byte (counting from 0) you can see that the tape
      is LUN 0 and the changer is LUN 1. The 0x80 set in the 5th byte
      for the tape drive means the driver should force access to
      path 0 (the library in this case was connected to one path only
      anyway).

      After the changes we can see the following in the dmesg output:

      scsi 0:3:0:0: RAID              HP       H241             1.18 \

      scsi 0:2:0:1: Medium Changer    HP       MSL G3 Series    8.70 \
      PQ: 0 ANSI: 5

      Showing that the changer is correctly identified as LUN 1 of
      bus 2 target 0. Before the change the changer device is not seen.

      ACPI, PCI: Penalize legacy IRQ used by ACPI SCI

      Nick Meier reported a regression with HyperV that "
        After rebooting the VM, the following messages are logged in syslog
        when trying to load the tulip driver:
          tulip: Linux Tulip drivers version 1.1.15 (Feb 27, 2007)
          tulip: 0000:00:0a.0: PCI INT A: failed to register GSI
          tulip: Cannot enable tulip board #0, aborting
          tulip: probe of 0000:00:0a.0 failed with error -16
        Errors occur in 3.19.0 kernel
        Works in 3.17 kernel.
      "

      According to the ACPI dump file posted by Nick at
      https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1440072

      The ACPI MADT table includes an interrupt source overridden entry for
      ACPI SCI:
      [236h 0566  1]                Subtable Type : 02 <Interrupt Source 
Override>
      [237h 0567  1]                       Length : 0A
      [238h 0568  1]                          Bus : 00
      [239h 0569  1]                       Source : 09
      [23Ah 0570  4]                    Interrupt : 00000009
      [23Eh 0574  2]        Flags (decoded below) : 000D
                                         Polarity : 1
                                     Trigger Mode : 3

      And in DSDT table, we have _PRT method to define PCI interrupts, which
      eventually goes to:
              Name (PRSA, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSB, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSC, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSD, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })

      According to the MADT and DSDT tables, IRQ 9 may be used for:
       1) ACPI SCI in level, high mode
       2) PCI legacy IRQ in level, low mode
      So there's a conflict in polarity setting for IRQ 9.

      Prior to commit cd68f6bd53cf ("x86, irq, acpi: Get rid of special
      handling of GSI for ACPI SCI"), ACPI SCI is handled specially and
      there's no check for conflicts between ACPI SCI and PCI legagy IRQ.
      And it seems that the HyperV hypervisor doesn't make use of the
      polarity configuration in IOAPIC entry, so it just works.

      Commit cd68f6bd53cf gets rid of the specially handling of ACPI SCI,
      and then the pin attribute checking code discloses the conflicts
      between ACPI SCI and PCI legacy IRQ on HyperV virtual machine,
      and rejects the request to assign IRQ9 to PCI devices.

      So penalize legacy IRQ used by ACPI SCI and mark it unusable if ACPI
      SCI attributes conflict with PCI IRQ attributes.

      i40e: Remove redundant and unneeded messages

      The kernel notifies all VXLAN capable registered drivers, i.e. any
      driver that implements ndo_add_vxlan_port(), of the addition of a
      port so that the driver can track which ports are in use.  There's
      no need to log this - it just fills the system log with useless and
      irksome noise.

      Also, when failing to init SR-IOV interfaces the driver was printing the
      same message twice. Just remove the inner printk and let the outer message
      catch enable as well as the other failures.

      i40e: Fix legacy interrupt mode in the driver

      This patch fixes the driver flow to take into account legacy interrupts.
      Over time we added code that assumes MSIX is the only mode that the
      driver runs in. It also enables a legacy workaround to trigger SWINT
      when the TX ring has non-cache aligned descriptors pending and interrupts
      are disabled.

      We work with a single vector in MSI mode too, so apply the same
      restrictions as Legacy.

      ARM: software-based priviledged-no-access support

      Provide a software-based implementation of the priviledged no access
      support found in ARMv8.1.

      Userspace pages are mapped using a different domain number from the
      kernel and IO mappings.  If we switch the user domain to "no access"
      when we enter the kernel, we can prevent the kernel from touching
      userspace.

      However, the kernel needs to be able to access userspace via the
      various user accessor functions.  With the wrapping in the previous
      patch, we can temporarily enable access when the kernel needs user
      access, and re-disable it afterwards.

      This allows us to trap non-intended accesses to userspace, eg, caused
      by an inadvertent dereference of the LIST_POISON* values, which, with
      appropriate user mappings setup, can be made to succeed.  This in turn
      can allow use-after-free bugs to be further exploited than would
      otherwise be possible.

      ARM: entry: provide uaccess assembly macro hooks

      Provide hooks into the kernel entry and exit paths to permit control
      of userspace visibility to the kernel.  The intended use is:

      - on entry to kernel from user, uaccess_disable will be called to
        disable userspace visibility
      - on exit from kernel to user, uaccess_enable will be called to
        enable userspace visibility
      - on entry from a kernel exception, uaccess_save_and_disable will be
        called to save the current userspace visibility setting, and disable
        access
      - on exit from a kernel exception, uaccess_restore will be called to
        restore the userspace visibility as it was before the exception
        occurred.

      These hooks allows us to keep userspace visibility disabled for the
      vast majority of the kernel, except for localised regions where we
      want to explicitly access userspace.

      ARM: entry: get rid of multiple macro definitions

       #else
        .macro baz
        ...
        .endm
       #endif
       #endif

      such as one defintion being updated, but the other definitions miss out.
      Where the contents of a macro needs to be conditional, the hint is in
      the first clause of this very sentence.  "contents" "conditional".  Not
      multiple separate definitions, especially not when much of the macro
      is the same between different configs.

      This patch fixes this bad style, which had caused the Thumb2 code to
      miss-out on the uaccess updates.

      f2fs: update extent tree in batches

      This patch introduce a new helper f2fs_update_extent_tree_range which can
      do extent mapping update at a specified range.

      The main idea is:
      1) punch all mapping info in extent node(s) which are at a specified 
range;
      2) try to merge new extent mapping with adjacent node, or failing that,
         insert the mapping into extent tree as a new node.

      In order to see the benefit, I add a function for stating time stamping
      count as below:

      uint64_t rdtsc(void)
      {
        uint32_t lo, hi;
        __asm__ __volatile__ ("rdtsc" : "=a" (lo), "=d" (hi));
        return (uint64_t)hi << 32 | lo;
      }

      My test environment is: ubuntu, intel i7-3770, 16G memory, 256g micron 
ssd.

      truncation path:  update extent cache from truncate_data_blocks_range
      non-truncataion path:     update extent cache from other paths
      total:                    all update paths

      a) Removing 128MB file which has one extent node mapping whole range of
      file:
      1. dd if=/dev/zero of=/mnt/f2fs/128M bs=1M count=128
      2. sync
      3. rm /mnt/f2fs/128M

      Before:
                total           count           average
      truncation:       7651022         32768           233.49

      Patched:
                total           count           average
      truncation:       3321            33              100.64

      b) fsstress:
      fsstress -d /mnt/f2fs -l 5 -n 100 -p 20
      Test times:               5 times.

      Before:
                total           count           average
      truncation:       5812480.6       20911.6         277.95
      non-truncation:   7783845.6       13440.8         579.12
      total:            13596326.2      34352.4         395.79

      Patched:
                total           count           average
      truncation:       1281283.0       3041.6          421.25
      non-truncation:   7355844.4       13662.8         538.38
      total:            8637127.4       16704.4         517.06

      1) For the updates in truncation path:
       - we can see updating in batches leads total tsc and update count 
reducing
         explicitly;
       - besides, for a single batched updating, punching multiple extent nodes
         in a loop, result in executing more operations, so our average tsc
         increase intensively.
      2) For the updates in non-truncation path:
       - there is a little improvement, that is because for the scenario that we
         just need to update in the head or tail of extent node, new interface
         optimize to update info in extent node directly, rather than removing
         original extent node for updating and then inserting that updated one
         into cache as new node.

      clk: pistachio: Fix PLL rate calculation in integer mode

      .recalc_rate callback for the fractional PLL doesn't take operating
      mode into account when calculating PLL rate. This results in
      the incorrect PLL rates when PLL is operating in integer mode.

      Operating mode of fractional PLL is based on the value of the
      fractional divider. Currently it assumes that the PLL will always
      be configured in fractional mode which may not be
      the case. This may result in the wrong output frequency.

      Also vco was calculated based on the current operating mode which
      makes no sense because .set_rate is setting operating mode. Instead,
      vco should be calculated using PLL settings that are about to be set.

      clk: pistachio: Fix override of clk-pll settings from boot loader

      PLL enable callbacks are overriding PLL mode (int/frac) and
      Noise reduction (on/off) settings set by the boot loader which
      results in the incorrect clock rate.

      PLL mode and noise reduction are defined by the DSMPD and DACPD bits
      of the PLL control register. PLL .enable() callbacks enable PLL
      by deasserting all power-down bits of the PLL control register,
      including DSMPD and DACPD bits, which is not necessary since
      these bits don't actually enable/disable PLL.

      This commit fixes the problem by removing DSMPD and DACPD bits
      from the "PLL enable" mask.

      One of the functions affected by this problem is .recalc_rate. It

      ====================
      act_bpf: remove spinlock in fast path

      v1 version had a race condition in cleanup path of bpf_prog.
      I tried to fix it by adding new callback 'cleanup_rcu' to 'struct 
tcf_common'
      and call it out of act_api cleanup path, but Daniel noticed
      (thanks for the idea!) that most of the classifiers already do action 
cleanup
      out of rcu callback.
      So instead this set of patches converts tcindex and rsvp classifiers to 
call
      tcf_exts_destroy() after rcu grace period and since action cleanup logic
      in __tcf_hash_release() is only called when bind and refcnt goes to zero,
      it's guaranteed that cleanup() callback is called from rcu callback.
      More specifically:
      patches 1 and 2 - simple fixes
      patches 2 and 3 - convert tcf_exts_destroy in tcindex and rsvp to call_rcu
      patch 5 - removes spin_lock from act_bpf

      The cleanup of actions is now universally done after rcu grace period
      and in the future we can drop (now unnecessary) call_rcu from 
tcf_hash_destroy()
      patch 5 is using synchronize_rcu() in act_bpf replacement path, since it's
      very rare and alternative of dynamically allocating 'struct tcf_bpf_cfg' 
just
      to pass it to call_rcu looks even less appealing.

      net_sched: act_bpf: remove spinlock in fast path

      Similar to act_gact/act_mirred, act_bpf can be lockless in packet 
processing
      with extra care taken to free bpf programs after rcu grace period.
      Replacement of existing act_bpf (very rare) is done with synchronize_rcu()
      and final destruction is done from tc_action_ops->cleanup() callback that 
is
      called from 
tcf_exts_destroy()->tcf_action_destroy()->__tcf_hash_release() when
      bind and refcnt reach zero which is only possible when classifier is 
destroyed.
      Previous two patches fixed the last two classifiers (tcindex and rsvp) to
      call tcf_exts_destroy() from rcu callback.

      Similar to gact/mirred there is a race between prog->filter and
      prog->tcf_action. Meaning that the program being replaced may use
      previous default action if it happened to return TC_ACT_UNSPEC.
      act_mirred race betwen tcf_action and tcfm_dev is similar.
      In all cases the race is harmless.
      Long term we may want to improve the situation by replacing the whole
      tc_action->priv as single pointer instead of updating inner fields one by 
one.

      Input: synaptics - fix handling of disabling gesture mode

      Bit 2 of the mode byte has dual meaning: it can disable reporting of
      gestures when touchpad works in Relative mode or normal Absolute mode,
      or it can enable so called Extended W-Mode when touchpad uses enhanced
      Absolute mode (W-mode). The extended W-Mode confuses our driver and
      causes missing button presses on some Thinkpads (x250, T450s), so let's
      make sure we do not enable it.

      Also, according to the spec W mode "... bit is defined only in Absolute
      mode on pads whose capExtended capability bit is set. In Relative mode and
      in TouchPads without this capability, the bit is reserved and should be
      left at 0.", so let's make sure we respect this requirement as well.

      i2c: allow specifying separate wakeup interrupt in device tree

      Instead of having each i2c driver individually parse device tree data in
      case it or platform supports separate wakeup interrupt, and handle
      enabling and disabling wakeup interrupts in their power management
      routines, let's have i2c core do that for us.

      Platforms wishing to specify separate wakeup interrupt for the device
      should use named interrupt syntax in their DTSes:

        interrupt-parent = <&intc1>;
        interrupts = <5 0>, <6 0>;
        interrupt-names = "irq", "wakeup";

      This patch is inspired by work done by Vignesh R <vigneshr@xxxxxx> for
      pixcir_i2c_ts driver.

      Note that the original code tried to preserve any existing wakeup
      settings from userspace but was not quite right in that regard:
      it would preserve wakeup flag set by userspace upon driver rebinding;
      but it would re-arm the wakeup flag if it was disabled by userspace.

      We think that resetting the flag upon re-binding the driver is proper
      behavior as the driver is responsible for setting up and handling
      wakeups.

      s390/sclp_vt220: support magic sysrequests

      Implement magic sysrequest handling for the VT220 terminal (also known as
      the Integrated ASCII console on the HMC/SE).
      To invoke a "magic sysrequest" function, press "Ctrl+o" followed by a
      second character that designates the debugging function.

      The handling of the sysrq is scheduled away from the SCLP IRQ context;
      because large amounts of sysrq output might fill up the console buffers.
      The console might deadlock because it cannot empty the buffers while still
      in the receiving IRQ context.  This behavior is the same as for the SCLP
      console.

      If a 3270 terminal is disconnected and later reconnected again,
      it gets an unsolicited device end. This is currently ignored and
      you have to hit the clear key to get the screen redrawn.
      Add an automatic full redraw of the screen for this case.

      perf probe: Support probing at absolute address

      It should be useful to allow 'perf probe' probe at absolute offset of a
      target. For example, when (u)probing at a instruction of a shared object
      in a embedded system where debuginfo is not avaliable but we know the
      offset of that instruction by manually digging.

      This patch enables following perf probe command syntax:

        # perf probe 0xffffffff811e6615

      And

        # perf probe /lib/x86_64-linux-gnu/libc-2.19.so 0xeb860

      In the above example, we don't need a anchor symbol, so it is possible
      to compute absolute addresses using other methods and then use 'perf
      probe' to create the probing points.

      v1 -> v2:
        Drop the leading '+' in cmdline;
        Allow uprobing at offset 0x0;
        Improve 'perf probe -l' result when uprobe at area without debuginfo.

      v2 -> v3:
        Split bugfix to a separated patch.

      Test result:

        # perf probe 0xffffffff8119d175 %ax
        # perf probe sys_write %ax

      perf probe: Fix error reported when offset without function

      This patch fixes a bug that, when offset is provided but function is
      lost, parse_perf_probe_point() will give a "" string as function name,
      so the checking code at the end of parse_perf_probe_point() become
      useless.  For example:

        # perf probe +0x1234
        Failed to find symbol  in kernel
          Error: Failed to add events.

      After this patch:

        # perf probe +0x1234
        Semantic error :Offset requires an entry function.
          Error: Command Parse Error.

      perf probe: Fix list result when address is zero

      When manually added uprobe point with zero address, 'perf probe -l'
      reports error. For example:

        # echo p:probe_libc/abs_0 /path/to/lib.bin:0x0 arg1=%ax > \
                 /sys/kernel/debug/tracing/uprobe_events

        # perf probe -l
        Error: Failed to show event list.

      Probing at 0x0 is possible and useful when lib.bin is not a normal
      shared object but is manually mapped. However, in this case kernel
      report:

        # cat /sys/kernel/debug/tracing/uprobe_events
        p:probe_libc/abs_0 /path/to/lib.bin:0x          (null) arg1=%ax

      This patch supports the above kernel output.

      ALSA: usb-audio: Avoid nested autoresume calls

      After the recent fix of runtime PM for USB-audio driver, we got a
      lockdep warning like:

        =============================================
        [ INFO: possible recursive locking detected ]
        4.2.0-rc8+ #61 Not tainted
        ---------------------------------------------
        pulseaudio/980 is trying to acquire lock:
         (&chip->shutdown_rwsem){.+.+.+}, at: [<ffffffffa0355dac>] 
snd_usb_autoresume+0x1d/0x52 [snd_usb_audio]
        but task is already holding lock:
         (&chip->shutdown_rwsem){.+.+.+}, at: [<ffffffffa0355dac>] 
snd_usb_autoresume+0x1d/0x52 [snd_usb_audio]

      This comes from snd_usb_autoresume() invoking down_read() and it's
      used in a nested way.  Although it's basically safe, per se (as these
      are read locks), it's better to reduce such spurious warnings.

      The read lock is needed to guarantee the execution of "shutdown"
      (cleanup at disconnection) task after all concurrent tasks are
      finished.  This can be implemented in another better way.

      Also, the current check of chip->in_pm isn't good enough for
      protecting the racy execution of multiple auto-resumes.

      This patch rewrites the logic of snd_usb_autoresume() & co; namely,
      - The recursive call of autopm is avoided by the new refcount,
        chip->active.  The chip->in_pm flag is removed accordingly.
      - Instead of rwsem, another refcount, chip->usage_count, is introduced
        for tracking the period to delay the shutdown procedure.  At
        the last clear of this refcount, wake_up() to the shutdown waiter is
        called.
      - The shutdown flag is replaced with shutdown atomic count; this is
        for reducing the lock.
      - Two new helpers are introduced to simplify the management of these
        refcounts; snd_usb_lock_shutdown() increases the usage_count, checks
        the shutdown state, and does autoresume.  snd_usb_unlock_shutdown()
        does the opposite.  Most of mixer and other codes just need this,
        and simply returns an error if it receives an error from lock.

      perf probe: Fix list result when symbol can't be found

      'perf probe -l' reports error if it is unable find symbol through
      address. Here is an example.

        # echo 'p:probe_libc/abs_5 /lib64/libc.so.6:0x5' >
                /sys/kernel/debug/tracing/uprobe_events
        # cat /sys/kernel/debug/tracing/uprobe_events
         p:probe_libc/abs_5 /lib64/libc.so.6:0x0000000000000005
        # perf probe -l
          Error: Failed to show event list

      Also, this situation triggers a logical inconsistency in
      convert_to_perf_probe_point() that, it returns ENOMEM but actually it
      never try strdup().

      This patch removes !tp->module && !is_kprobe condition, so it always
      uses address to build function name if symbol not found.

      Test result:

        # perf probe -l
          probe_libc:abs_5     (on 0x5 in /lib64/libc.so.6)

      perf probe: Prevent segfault when reading probe point with absolute 
address

      'perf probe -l' panic if there is a manually inserted probing point with
      absolute address. For example:

        # echo 'p:probe/abs_ffffffff811e6615 0xffffffff811e6615' > 
/sys/kernel/debug/tracing/kprobe_events
        # perf probe -l
        Segmentation fault (core dumped)

      This patch fix this problem by considering the situation that
      "tp->symbol == NULL" in find_perf_probe_point_from_dwarf() and
      find_perf_probe_point_from_map().

      After this patch:

        # perf probe -l
        probe:abs_ffffffff811e6615 (on SyS_write+5@fs/read_write.c)

      And when debug info is missing:

        # rm -rf ~/.debug
        # mv /lib/modules/4.2.0-rc1+/build/vmlinux 
/lib/modules/4.2.0-rc1+/build/vmlinux.bak
        # perf probe -l
        probe:abs_ffffffff811e6615 (on sys_write+5)

      MIPS: MT: Remove "weak" from vpe_run() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
      decl")).

      That's not a problem for vpe_run() because Kconfig ensures there's never
      more than one definition:

        - vpe_run() is defined in arch/mips/kernel/vpe-mt.c if
          CONFIG_MIPS_VPE_LOADER_MT=y

        - vpe_run() is defined in arch/mips/mti-malta/malta-amon.c if
          CONFIG_MIPS_CMP=y

        - CONFIG_MIPS_VPE_LOADER_MT cannot be set if CONFIG_MIPS_CMP=y

      But it's simpler to verify correctness if we remove "weak" from the 
picture
      and test the config symbols directly.

      Remove "weak" from the vpe_run() declaration and use #if to test whether a
      definition should be present.

      MIPS: VPE: Exit vpe_release() early if vpe_run() isn't defined

      vpe_run() is a weak symbol.  If there's no definition of it, its value is
      zero.

      If vpe_run is zero, return failure early.  We're going to fail anyway, so
      there's no point in getting a VPE and attempting to load it.

      MIPS: Remove "weak" from platform_maar_init() declaration

      Weak header file declarations are error-prone because they make every
      definition weak, and the linker chooses one based on link order (see
      10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node
      decl")).

      platform_maar_init() is defined in:

        - arch/mips/mm/init.c (where it is marked "weak")
        - arch/mips/mti-malta/malta-memory.c (without annotation)

      The "weak" attribute on the platform_maar_init() extern declaration 
applies
      to the platform-specific definition in arch/mips/mti-malta/malta-memory.c,
      so both definitions are weak, and which one we get depends on link order.

      Remove the "weak" attribute from the declaration.  That makes the malta
      definition strong, so it will always be preferred if it is present.

      MIPS: ops-emma2rh: Drop nonsensical db_assert

      The db_assert call checks whether the bus_num pointer is non-NULL, but
      does so after said pointer has been dereferenced by the assignment on
      the previous line. Thus the check is pointless & likely to have been
      optimised out by the compiler anyway. The check_args function is static
      & only ever called from the local file with bus_num being a pointer to
      an on-stack variable, so the check seems somewhat overzealous anyway.
      Simply remove it.

      MIPS: octeon: Replace the homebrewn flow handler

      The gpio interrupt handling of octeon contains a homebrewn flow
      handler which calls either handle_level_irq or handle_edge_irq
      depending on the trigger type. Thats an extra conditional and call in
      the interrupt handling path. The proper way to handle different types
      and therefor different flows is to update the handler in the
      irq_set_type() callback.

      Remove the extra indirection and add the handler update to
      octeon_irq_ciu_gpio_set_type(). At mapping time it defaults to
      handle_level_irq which gets updated if the device tree contains a
      different trigger type.

      is zero because its a complete noop:

      disable_irq_nosync() merily increments the disable count without
      actually masking the interrupt. enable_irq() soleley decrements the
      disable count without touching the interrupt chip. The interrupt
      cannot arrive again because the complete call chain runs with
      interrupts disabled.

      MIPS: cpu-probe: Fix VTLB/FTLB configuration for R6

      R6 has dropped the MMUExtDef field from the config4 register and it
      now returns 0. However, the return value means nothing in that case
      and the only supported configuration for R6 is the VTLB+FTLB
      (MMUextDef == 3). As a result, rework the code so that the correct
      value is set for R6 cores.

      Add a default case for the FTLB enable/disable code. This will be used
      to detect that something went wrong in the set_ftlb_enable() function
      either because that function knows nothing about the running core, or
      simply because the core can't turn its FTLB on/off.

      MIPS: mips-cm: Extend CM accessors for 64-bit CPUs

      Previously, the CM accessors were only accessing CM registers as u32
      types instead of using the native CM register with. However, newer CMs

      (CM3) hold all the useful configuration bits in the lower half of the
      64-bit registers (at least most of them) so they can still be accessed
      using the current 32-bit accessors.

      Since our common driver need support main chip and PMU
      at the same time, that means it will register two
      pinctrl device, and the pinctrl_desc structure should
      be used two times.

      But pinctrl_desc use global static definition, then
      the latest registered pinctrl device will overwrite
      the old one's, all members in pinctrl_desc will set to
      the new one's, such as name, pins and pins numbers, etc.
      This is a bug.

      Move pinctrl_desc into mtk_pinctrl, assign new value for
      each pinctrl device to fix it.

      powerpc/PCI: Disable MSI/MSI-X interrupts at PCI probe time in OF case

      Since commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if
      kernel doesn't support MSI"), the setup of dev->msi_cap/msix_cap and the
      disable of MSI/MSI-X interrupts isn't being done at PCI probe time, as
      the logic responsible for this was moved in the aforementioned commit
      from pci_device_add() to pci_setup_device(). The latter function is not
      reachable on PowerPC pseries platform during Open Firmware PCI probing
      time.

      This exhibits as drivers not being able to enable MSI, eg:

        bnx2x 0000:01:00.0: no msix capability found

      This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X
      during PCI probe time on pSeries platform.

      PCI: Make pci_msi_setup_pci_dev() non-static for use by arch code

      Commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel
      doesn't support MSI") changed the location of the code that initialises
      dev->msi_cap/msix_cap and then disables MSI/MSI-X interrupts at PCI
      probe time in devices that have this flag set. It moved the code from
      pci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(),
      called by pci_setup_device().

      The pseries PCI probing code does not call pci_setup_device(), so since
      the aforementioned commit the function pci_msi_setup_pci_dev() is not
      called and MSI/MSI-X interrupts are left enabled. Additionally because
      dev->msi_cap/msix_cap are not initialised no driver can ever enable
      MSI/MSI-X.

      To fix this, the pseries PCI probe should manually call
      pci_msi_setup_pci_dev(), so this patch makes it non-static.

      Fixes: 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel 
doesn't support MSI")

      ath10k: add qca6164 support

      This adds additional 0x0041 PCI Device ID
      definition to ath10k for QCA6164 which is a 1
      spatial stream sibling of the QCA6174 (which is 2
      spatial stream chip).

      The QCA6164 needs a dedicated board.bin file which
      is different than the one used for QCA6174. If the
      board.bin is wrong the device will crash early
      while trying to boot firmware. The register dump
      will look like this:

       ath10k_pci 0000:02:00.0: firmware register dump:

      ath10k: add spectral scan support for 10.4 fw

      To enable/configure spectral scan parameters in 10.4 firmware, existing
      wmi spectral related functions can be reused. Link those functions in
      10.4 wmi ops table.

      In addition, adjust bin size (only when size is 68 bytes) before reporting
      bin samples to user space. The background for this adjustment is that
      qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
      mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
      carries band edge detection data (+32) mainly used in radar detection
      purpose. Additional last 4 bytes are stripped to make bin size valid one.

      This bin size adjustment will happen only for qca99x0, all other chipsets
      will report proper bin sizes (64/128) without extra 4 bytes being added
      at the end. The changes are validated in qca99x0 using 10.4 firmware.

      gpio: omap: fix clk_prepare/unprepare usage

      As per CCF documentation (clk.txt) the clk_prepare/unprepare APIs
      are not allowed in atomic context. But now OMAP GPIO driver
      uses them while applying debounce settings and as part
      of PM runtime irqsafe operations:

      - omap_gpio_debounce() is holding the lock with IRQs off.
        + omap2_set_gpio_debounce()
         + clk_prepare_enable()
          + clk_prepare() this one might sleep.

      - pm_runtime_get_sync() is holding the lock with IRQs off
        + omap_gpio_runtime_suspend()
          + raw_spin_lock_irqsave()
          + omap_gpio_dbck_disable()
            + clk_disable_unprepare()

      Hence, fix it by moeving dbclk prepare/unprepare in OMAP GPIO
      omap_gpio_probe/omap_gpio_remove. Also, while here, ensure that
      debounce functionality is disabled if clk_get() failed,
      because otherwise kernel will carsh in omap2_set_gpio_debounce().

      gpio: omap: fix omap2_set_gpio_debounce

      According to TRMs:

      Required input line stable =
        (the value of the GPIO_DEBOUNCINGTIME[7:0].DEBOUNCETIME + 1) Ã?â?? 31,
      where the value of the GPIO_DEBOUNCINGTIME[7:0].DEBOUNCETIME bit field
      is from 0 to 255.

      But now omap2_set_gpio_debounce() will calculate debounce time and
      behave incorrectly in the following cases:
      1) requested debounce time is !0 and <32
         calculated DEBOUNCETIME = 0x1 == 62 us;
         expected value of DEBOUNCETIME = 0x0 == 31us
      2) requested debounce time is 0
         calculated DEBOUNCETIME = 0x1 == 62 us;
         expected: disable debounce and DEBOUNCETIME = 0x0
      3) requested debounce time is >32 and <63
         calculated DEBOUNCETIME = 0x0 and debounce will be disabled;
         expected: enable debounce and DEBOUNCETIME = 0x1 == 62 us

      Hence, rework omap2_set_gpio_debounce() to fix above cases:
      1) introduce local variable "enable" and use it to identify
      when debounce need to be enabled or disabled. Disable debounce
      if requested debounce time is 0.
      2) use below formula for debounce time calculation:
         debounce = (DIV_ROUND_UP(debounce, 31) - 1) & 0xFF;

      This is because desc->lock is raw_spinlock and is held when 
chv_gpio_irq_ack()
      is called by the genirq core. chv_gpio_irq_ack() in turn takes pctrl->lock
      which in -rt is an rt-mutex causing might_sleep() rightfully to complain 
about
      sleeping function called from invalid context.

      In order to keep -rt happy but at the same time make sure that register
      accesses get serialized, convert the driver to use raw_spinlock instead.

      pinctrl: baytrail: Use raw_spinlock for locking

      The Intel Baytrail pinctrl driver implements irqchip callbacks which are
      called with desc->lock raw_spinlock held. In mainline this is fine because
      spinlock resolves to raw_spinlock. However, running the same code in -rt 
we
      get:

        ...

      This is because in -rt spinlocks are preemptible so taking the driver
      private spinlock in irqchip callbacks causes might_sleep() to trigger.

      In order to keep -rt happy but at the same time make sure that register
      accesses get serialized, convert the driver to use raw_spinlock instead.

      Also shorten the critical section a bit in few places.

      surface pro 3: Add support driver for Surface Pro 3 buttons

      Since Surface Pro 3 does not follow the specs of "Windows ACPI Design
      Guide for SoC Platform", code in drivers/input/misc/soc_array.c can
      not detect these buttons on it. According to bios implementation,
      Surface Pro 3 encapsulates these buttons in a device named "VGBI",
      with _HID "MSHW0028". When any of the buttons is pressed, a specify
      ACPI notification code for this button will be delivered to "VGBI". For
      example, if power button is pressed down, ACPI notification code of 0xc6
      will be sent by Notify(VGBI, 0xc6).

      This patch leverages "VGBI" to distinguish different ACPI notification
      code from Power button, Home button, Volume button, then dispatches these
      code to input layer. Lid is already covered by acpi button driver, so
      there's no need to rewrite.

      drm/i915/skl: Update DDI buffer translation programming.

      SKL-Y can now use the same programming for all VccIO values after an
      adjustment to I_boost.  SKL-U DP table adjustments.

      1. Remove SKL Y 0.95V from "SKL H and S" columns in all tables. The
         other SKL Y column removes the "0.85V VccIO" so it now applies to all
         voltages.

      2. DP table changes SKL U 400mV+0db dword 0 value from 2016h to 201Bh.

      3. DP table changes SKL U 600mv+0db dword 0 value from 2016h to 201Bh.

      4. DP table increases I_boost to level 3 for SKL Y 400mv+9.5db.

      v2: Fix compilation warnings as pointed by Paulo.

      ALSA: hda - Fix widget sysfs tree corruption after refresh

      When snd_hdac_refresh_widget_sysfs() is called before the first
      hda_widget_sysfs_init(), the next call overrides and eventually
      fails.  This results in unexpected Oops, something like:
        BUG: unable to handle kernel NULL pointer dereference at 
00000000000000c8
        IP: [<ffffffff8180e2a3>] hdmi_chmap_ctl_info+0x23/0x40

      The fix is to add a check of the existing sysfs tree.  Also, for more
      safety, this patch adds the checks of device_is_registered() in
      snd-hdac_refresh_wdiget_sysfs(), too.

      dmaengine: hdmac: Add memset capabilities

      Just like for the XDMAC, the SoCs that embed the HDMAC don't have any kind
      of GPU, and need to accelerate a few framebuffer-related operations 
through
      their DMA controller.

      However, unlike the XDMAC, the HDMAC doesn't have the memset capability
      built-in. That can be easily emulated though, by doing a transfer with a
      fixed address on the variable that holds the value we want to set.

      In commit 1e052be69d04 ("net_sched: destroy proto tp when all filters are

      I added a check in u32_destroy() to see if all real filters are gone
      for each tp, however, that is only done for root_ht, same is needed
      for others.

      This can be reproduced by the following tc commands:

      tc filter add dev eth0 parent 1:0 prio 5 handle 15: protocol ip u32 
divisor 256
      tc filter add dev eth0 protocol ip parent 1: prio 5 handle 15:2:2 u32

      This patch series adds some documentation about DSA as a subsystem as well
      as the SF2 driver since it slightly diverges from your average DSA driver 
;)

      LSM: restore certain default error codes

      While in most cases commit b1d9e6b064 ("LSM: Switch to lists of hooks")
      retained previous error returns, in three cases it altered them without
      any explanation in the commit message. Restore all of them - in the
      security_old_inode_init_security() case this led to reiserfs using
      uninitialized data, sooner or later crashing the system (the only other
      user of this function - ocfs2 - was unaffected afaict, since it passes
      pre-initialized structures).

      net: fec: use reinit_completion() in mdio accessor functions

      Rather than re-initialising the entire completion on every mdio access,
      use reinit_completion() which only resets the completion count.  This
      avoids possible reinitialisation of the contained spinlock and waitqueue
      while they may be in use (eg, mid-completion.)

      Such an event could occur if there's a long delay in interrupt handling
      causing the mdio accessor to time out, then a second access comes in
      while the interrupt handler on a different CPU has called complete().
      Another scenario where this has been observed is while locking has
      been missing at the phy layer, allowing concurrent attempts to access
      the MDIO bus.

      net: phy: add locking to phy_read_mmd_indirect()/phy_write_mmd_indirect()

      The phy layer is missing locking for the above two functions - it
      has been observed that two threads (userspace and the phy worker
      thread) can race, entering the bus ->write or ->read functions
      simultaneously.

      This causes the FEC driver to initialise a completion while another
      thread is waiting on it or while the interrupt is calling complete()
      on it, which causes spinlock unlock-without-lock, spinlock lockups,
      and completion timeouts.

MMD registers.")

      RDS: Fix rds MR reference count in rds_rdma_unuse()

      rds_rdma_unuse() drops the mr reference count which it hasn't
      taken. Correct way of removing mr is to remove mr from the tree
      and then rdma_destroy_mr() it first, then rds_mr_put() to decrement
      its reference count. Whichever thread holds last reference will free
      the mr via rds_mr_put()

      This bug was triggering weird null pointer crashes. One if the trace
      for it is captured below.

      vxlan: re-ignore EADDRINUSE from igmp_join

      Before 56ef9c909b40[1] it used to ignore all errors from igmp_join().
      That commit enhanced that and made it error out whatever error happened
      with igmp_join(), but that's not good because when using multicast
      groups vxlan will try to join it multiple times if the socket is reused
      and then the 2nd and further attempts will fail with EADDRINUSE.

      As we don't track to which groups the socket is already subscribed, it's
      okay to just ignore that error.

      net: compile renesas directory if NET_VENDOR_RENESAS is configured

      Currently the renesas ethernet driver directory is compiled if SH_ETH is
      configured rather than NET_VENDOR_RENESAS. Although incorrect that was
      quite harmless as until recently as SH_ETH configured the only driver in
      the renesas directory. However, as of c156633f1353 ("Renesas Ethernet AVB
      driver proper") the renesas directory includes another driver, configured

      r8169: Add values missing in @get_stats64 from HW counters

      The r8169 driver collects statistical information returned by
      @get_stats64 by counting them in the driver itself, even though many
      (but not all) of the values are already collected by tally counters
      (TCs) in the NIC.  Some of these TC values are not returned by
      @get_stats64.  Especially the received multicast packages are missing
      from /proc/net/dev.

      Rectify this by fetching the TCs and returning them from
      rtl8169_get_stats64.

      The counters collected in the driver obviously disappear as soon as the
      driver is unloaded so after a driver is loaded the counters always start
      at 0. The TCs on the other hand are only reset by a power cycle.  Without
      further considerations the values collected by the driver would not match
      up against the TC values.

      This patch introduces a new function rtl8169_reset_counters which
      resets the TCs.  Also, since rtl8169_reset_counters shares most of
      its code with rtl8169_update_counters, refactor the shared code into
      two new functions  rtl8169_map_counters and rtl8169_unmap_counters.

      Unfortunately chip versions prior to RTL_GIGA_MAC_VER_19 don't allow
      to reset the TCs programatically.  Therefore introduce an addition to
      the rtl8169_private struct and a function rtl8169_init_counter_offsets
      to store the TCs at first rtl_open.  Use these values as offsets in
      rtl8169_get_stats64.  Propagate a failure to reset *and* update the
      counters up to rtl_open and emit a warning message, if so.

      ACPICA: Disassembler: Cleanup acpi_gbl_db_opt_verbose acpiexec usage

      ACPICA commit 42d7ad7bfb1cfb95183c1386c77509f2036f521d

      When acpi_gbl_db_opt_verbose is used in acpi_dm_descending_op() (invoked 
by
      acpi_dm_disassemble()), it is actually exported by the disassembler but 
used
      by the debugger to distinguish the output of the disassembler for 
different
      debugger commands. It is by default TRUE but is set to FALSE for control
      method disassembly command - "disassemble". So it's initialization should
      be a part of the ACPI_DISASSEMBLER conditioned code. This patch uses
      ACPI_INIT_GLOBAL to achieve a clean manner so that when ACPI_DISASSEMBLER
      is not defined, ACPI_DEBUGGER conditioned code needn't link to this 
option.
      Since it is a disassembler exported variable, it is renamed to
      acpi_gbl_dm_opt_Verbose in this patch.

      As VERBOSE_PRINT() macro has only one user, this patch also removes the
      definition of this macro. Lv Zheng.

      This patch doesn't affect Linux kernel.

      ACPICA commit 969989cf7f85e2a2a0cd048cd25fc706246a48a2

      This patch cleans up the following global variable - 
acpi_gbl_db_opt_disasm:
      The setting is used to control the full disassembly feature for iasl. ACPI
      debugger (acpiexec) shall have nothing to do with it. Actually, acpiexec
      never links to ad_aml_disassemble().

      This patch thus renames this global option to acpi_gbl_dm_opt_disasm and
      removes all acpiexec and debugger references on it. Lv Zheng.

      ACPICA: Debugger: Split debugger initialization/termination APIs

      ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432

      It is likely that the debugger is enabled only when a userspace program
      explicitly tells a kernel to do so, so it shouldn't be initialized as
      early as current implementation.

      The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to 
call
      the new APIs by itself. And BSD developers may also get notified to invoke
      the APIs for DDB enabling. Lv Zheng.

      This patch doesn't affect Linux kernel as debugger is currently not 
enabled
      in the Linux kernel.

      ACPICA: Tables: Fix global table list issues by removing fixed table 
indexes

      ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941

      The fixed table indexes leave holes in the global table list:
       1. One hole can be seen when there is only 1 FACS provided by the BIOS.
       2. Tow holes can be seen when it is a reduced hardware platform.
      The holes do not break OSPMs but have broken ACPI debugger "tables"
      command.

      Also the "fixed table indexes" mechanism may make the descriptors of the
      standard tables installed earlier than DSDT to be overwritten by the
      descriptors of the fixed tables. For example, FACP disappears from the
      global table list after DSDT is installed.

      This patch fixes all above issues by removing the "fixed table indexes"
      mechanism which is too complicated to be maintained in a regression safe
      manner. After removal, the table loader will determine the indexes of the
      fixed tables. Lv Zheng.

      This mode emits AML code along with the ASL code.

      Emits the correct AML offset for the AML code.

      ppp: implement x-netns support

      Let packets move from one netns to the other at PPP encapsulation and
      decapsulation time.

      PPP units and channels remain in the netns in which they were
      originally created. Only the net_device may move to a different
      namespace. Cross netns handling is thus transparent to lower PPP
      layers (PPPoE, L2TP, etc.).

      PPP devices are automatically unregistered when their netns gets
      removed. So read() and poll() on the unit file descriptor will
      respectively receive EOF and POLLHUP. Channels aren't affected.

      net/mlx5e: Avoid accessing NULL pointer at ndo_select_queue

      To avoid multiply/division operations on the data path,
      we hold a {channel, tc}==>txq mapping table.
      We held this mapping table inside the channel object that is
      being destroyed upon some configuration operations (e.g MTU change).
      So in case ndo_select_queue occurs during such a configuration operation,
      it may access a NULL channel pointer, resulting in kernel panic.
      To fix this issue we moved the {channel, tc}==>txq mapping table
      outside the channel object so that it will be available also
      during such configuration operations.

      mtip32x: fix regression introduced by blk-mq per-hctx flush

      Hi,

      After commit f70ced091707 (blk-mq: support per-distpatch_queue flush
      machinery), the mtip32xx driver may oops upon module load due to walking
      off the end of an array in mtip_init_cmd.  On initialization of the
      flush_rq, init_request is called with request_index >= the maximum queue
      depth the driver supports.  For mtip32xx, this value is used to index
      into an array.  What this means is that the driver will walk off the end
      of the array, and either oops or cause random memory corruption.

      The problem is easily reproduced by doing modprobe/rmmod of the mtip32xx
      driver in a loop.  I can typically reproduce the problem in about 30
      seconds.

      Now, in the case of mtip32xx, it actually doesn't support flush/fua, so
      I think we can simply return without doing anything.  In addition, no
      other mq-enabled driver does anything with the request_index passed into
      init_request(), so no other driver is affected.  However, I'm not really
      sure what is expected of drivers.  Ming, what did you envision drivers
      would do when initializing the flush requests?

      RDS: Assorted bug fixes

      We would like to improve RDS upstream support and in that context, I
      started playing with it.  But run into number of issues including as
      basic is RDS IB RDMA doesn't work. As part of the debug, I ended up
      creating the $subject series which has bunch of assorted fixes. At
      least with this series I can run RDS IB RDMA and other tests
      successfully.

      Some of these fixes have been done by Chris Meson, Andy Grover and
      Zach Brown while at Oracle. There are still more kinks with FMR and
      error handling and I plan to address them in a follow up series.

      Series generated against Linus's master(v4.2-rc-7) but also applies
      against next-next cleanly. Its tested on Oracle hardware with IB
      fabric for both bcopy as well as RDMA mode. I don't have access
      to iWARP hardware so any testing help on iWARP hardware appreciated.

      RDS: return EMSGSIZE for oversize requests before processing/queueing

      rds_send_queue_rm() allows for the "current datagram" being queued
      to exceed SO_SNDBUF thresholds by checking bytes queued without
      counting in length of current datagram. (Since sk_sndbuf is set
      to twice requested SO_SNDBUF value as a kernel heuristic this
      is usually fine!)

      If this "current datagram" squeezing past the threshold is itself
      many times the size of the sk_sndbuf threshold itself then even
      twice the SO_SNDBUF does not save us and it gets queued but
      cannot be transmitted. Threads block and deadlock and device
      becomes unusable. The check for this datagram not exceeding
      SNDBUF thresholds (EMSGSIZE) is not done on this datagram as
      that check is only done if queueing attempt fails.
      (Datagrams that follow this datagram fail queueing attempts, go
      through the check and eventually trip EMSGSIZE error but zero
      length datagrams silently fail!)

      This fix moves the check for datagrams exceeding SNDBUF limits
      before any processing or queueing is attempted and returns EMSGSIZE
      early in the rds_sndmsg() code. This change also ensures that all
      datagrams get checked for exceeding SNDBUF/sk_sndbuf size limits
      and the large datagrams that exceed those limits do not get to
      rds_send_queue_rm() code for processing.

      RDS: make sure rds_send_drop_to properly takes the m_rs_lock

      rds_send_drop_to() is used during socket tear down to find all the
      messages on the socket and flush them .  It can race with the
      acking code unless it takes the m_rs_lock on each and every message.

      This plugs a hole where we didn't take m_rs_lock on any message that
      didn't have the RDS_MSG_ON_CONN set.  Taking m_rs_lock avoids
      double frees and other memory corruptions as the ack code trusts
      the message m_rs pointer on a socket that had actually been freed.

      We must take m_rs_lock to access m_rs.  Because of lock nesting and
      rs access, we also need to acquire rs_lock.

      RDS: Make sure we do a signaled send for large-send

      WR(Work Requests )always generate a WC(Work Completion) with
      signaled send. Default RDS ib code is setup for un-signaled
      completion. Since RDS connction is persistent, we can end up
      sending the data even after large-send when the remote end is
      not active(for any reason).

      By doing  a signaled send at least once per large-send,
      we can at least detect the problem in work completion
      handler there by avoiding sending more data to
      inactive remote.

      RDS: make sure we post recv buffers

      If we get an ENOMEM during rds_ib_recv_refill, we might never come
      back and refill again later. Patch makes sure to kick krdsd into

      To achieve this we add RDS_RECV_REFILL flag and update in the refill
      path based on that so that at least some therad will keep posting
      receive buffers.

      Since krdsd and softirq both might race for refill, we decide to
      schedule on work queue based on ring_low instead of ring_empty.

      RDS: always free recv frag as we free its ring entry

      We were still seeing rare occurrences of the WARN_ON(recv->r_frag) which
      indicates that the recv refill path was finding allocated frags in ring
      entries that were marked free. These were usually followed by OOM crashes.
      They only seem to be occurring in the presence of completion errors and
      connection resets.

      This patch ensures that we free the frag as we mark the ring entry free.
      This should stop the refill path from finding allocated frags in ring
      entries that were marked free.

      writeback: sync_inodes_sb() must write out I_DIRTY_TIME inodes and always 
call wait_sb_inodes()

      e79729123f63 ("writeback: don't issue wb_writeback_work if clean")
      updated writeback path to avoid kicking writeback work items if there
      are no inodes to be written out; unfortunately, the avoidance logic
      was too aggressive and broke sync_inodes_sb().

      * sync_inodes_sb() must write out I_DIRTY_TIME inodes but I_DIRTY_TIME
        inodes dont't contribute to bdi/wb_has_dirty_io() tests and were
        being skipped over.

      * inodes are taken off wb->b_dirty/io/more_io lists after writeback
        starts on them.  sync_inodes_sb() skipping wait_sb_inodes() when
        bdi_has_dirty_io() breaks it by making it return while writebacks
        are in-flight.

      This patch fixes the breakages by

      * Removing bdi_has_dirty_io() shortcut from bdi_split_work_to_wbs().
        The callers are already testing the condition.

      * Removing bdi_has_dirty_io() shortcut from sync_inodes_sb() so that
        it always calls into bdi_split_work_to_wbs() and wait_sb_inodes().

      regulator: lp872x: use the private data instead of updating I2C device 
platform data

      Currently, lp872x driver parses the DT and copies values into the
      'cl->dev.platform_data' if 'of_node' exists.
      This may have architectural issue. Platform data is configurable through
      the DT or I2C board info inside the platform area.
      However, lp872x driver changes this configuration when it is loaded.

      The lp872x driver should get data from the platform side and use the 
private
      data, 'lp872x->pdata' instead of changing the original platform data.

      tcp: refine pacing rate determination

      When TCP pacing was added back in linux-3.12, we chose
      to apply a fixed ratio of 200 % against current rate,
      to allow probing for optimal throughput even during
      slow start phase, where cwnd can be doubled every other gRTT.

      At Google, we found it was better applying a different ratio
      while in Congestion Avoidance phase.
      This ratio was set to 120 %.

      We've used the normal tcp_in_slow_start() helper for a while,
      then tuned the condition to select the conservative ratio
      as soon as cwnd >= ssthresh/2 :

      - After cwnd reduction, it is safer to ramp up more slowly,
        as we approach optimal cwnd.
      - Initial ramp up (ssthresh == INFINITY) still allows doubling
        cwnd every other RTT.

      phylib: Make PHYs children of their MDIO bus, not the bus' parent.

      commit 18ee49ddb0d2 ("phylib: rename mii_bus::dev to mii_bus::parent")
      changed the parent of PHY devices from the bus to the bus parent.

      Then, commit 4dea547fef1b ("phylib: rework to prepare for OF
      registration of PHYs") moved the code into phy_device.c

      At this point, it is somewhat unclear why the change was seen as
      necessary.  But, when we look at the device model tree in
      /sys/devices, it is clearly incorrect.  The PHYs should be children of
      their MDIO bus.

      Change the PHY's parent device to be the MDIO bus device.

      tcp: fix slow start after idle vs TSO/GSO

      slow start after idle might reduce cwnd, but we perform this
      after first packet was cooked and sent.

      With TSO/GSO, it means that we might send a full TSO packet
      even if cwnd should have been reduced to IW10.

      Moving the SSAI check in skb_entail() makes sense, because
      we slightly reduce number of times this check is done,
      especially for large send() and TCP Small queue callbacks from
      softirq context.

      As Neal pointed out, we also need to perform the check
      if/when receive window opens.

      Tested:

      Following packetdrill test demonstrates the problem
      // Test of slow start after idle

      ASoC: arizona: Poll for FLL clock OK rather than use interrupts

      The extcon driver takes the DAPM mutex from within the interrupt thread
      in several places, which makes it possible to get into a situation where
      the interrupt thread is blocked waiting on the DAPM mutex whilst a DAPM
      sequence is running which is attempting to configure the FLL. In this
      case the FLL completion can't be completed as as the IRQ handler is
      ONE_SHOT, which cause the FLL lock to use the full time out (250mS) and
      report that the process timed out.

      It is not really practical to make the extcon driver not take the DAPM
      mutex from within the interrupt thread, at least not without extensive
      modification. So this patch fixes the issue by switching the wait for
      the FLL lock to polling. A few fast polls are done first as the FLL
      should lock quickly for a good quality reference clock, (indeed it hits
      on the first poll on my system) and it will poll every 20mS after that
      until it times out.

      Added rt5677_spi_read() and refactored rt5677_spi_write() so that
      an arbitrary block in the DSP address space can be read/written
      via SPI. For example, this allows us to load an ELF DSP firmware
      with sparse sections, and stream audio samples from DSP ring buffer.

      Docs: dt: add generic MSI bindings

      Currently msi-parent is used in a couple of drivers despite being fairly
      underspecified. This patch adds a generic binding for MSIs (including
      the existing msi-parent property) enabling the description of platform
      devices capable of using MSIs.

      While MSIs are primarily distinguished by doorbell and payload, some MSI
      controllers (e.g. the GICv3 ITS) also use side-band information
      accompanying the write to identify the master which originated the MSI,
      to allow for sandboxing. This sideband information is non-probeable and
      needs to be described in the DT. Other MSI controllers may have
      additional configuration details which need to be described per-master.

      This patch adds a generic msi-parent binding document, extending the
      de-facto standard with a new (optional) #msi-cells which can be used to
      express any per-master configuration and/or sideband data. This is
      sufficient to describe non-hotpluggable devices.

      For busses where sideband data may be derived from some bus-specific
      master ID scheme, other properties will be required to describe the
      mapping.

      drivercore: Fix unregistration path of platform devices

      The unregister path of platform_device is broken. On registration, it
      will register all resources with either a parent already set, or
      type==IORESOURCE_{IO,MEM}. However, on unregister it will release
      everything with type==IORESOURCE_{IO,MEM}, but ignore the others. There
      are also cases where resources don't get registered in the first place,
      like with devices created by of_platform_populate()*.

      Fix the unregister path to be symmetrical with the register path by
      checking the parent pointer instead of the type field to decide which
      resources to unregister. This is safe because the upshot of the
      registration path algorithm is that registered resources have a parent
      pointer, and non-registered resources do not.

      * It can be argued that of_platform_populate() should be registering
        it's resources, and they argument has some merit. However, there are
        quite a few platforms that end up broken if we try to do that due to
        overlapping resources in the device tree. Until that is fixed, we need
        to solve the immediate problem.

      If the internal call to of_address_to_resource() fails, we end up
      looping forever in of_find_matching_node_by_address().  This can be
      caused by a defective device tree, or calling with an incorrect

      Fix by calling of_find_matching_node() unconditionally at the end of

      of/platform: add function to populate default bus

      When a default bus like the simple-bus should be used someone had to
      call of_platform_populate() with the default match table. This match
      table was not exported, so it is impossible for code build as a module
      to use this. Instead of exporting of_default_bus_match_table, add a new
      function which uses this default match table and populates the bus.

      regulator: isl9305: Export OF module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
      regardless of the mechanism that was used to register the device
      (i.e: OF or board code) and the table that is used later to match
      the driver with the device (i.e: I2C id table or OF match table).

      So drivers needs to export the I2C id table and this be built into
      the module or udev won't have the necessary information to autoload
      the needed driver module when the device is added.

      But this means that OF-only drivers needs to have both OF and I2C id
      tables that have to be kept in sync and also the dev node compatible
      manufacturer prefix is stripped when reporting the MODALIAS. Which can
      lead to issues if two vendors use the same I2C device name for example.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an SPI device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table even when
      is unused now to prevent breaking module loading when the core changes.

      ARM: mm: improve do_ldrd_abort macro

      Improve the do_ldrd_abort macro code - firstly, it inefficiently checks
      for the LDRD encoding by doing a multi-stage test of various bits.  This
      can be simplified by generating a mask, bitmasking the instruction and
      then comparing the result.

      Secondly, we want to be able to test the result rather than branching
      to do_DataAbort, so remove the branch at the end and rename the macro
      to 'teq_ldrd' to reflect it's new usage.  teq_ldrd macro returns 'eq'
      if the instruction was a LDRD.

      The event mask length is determined by the highest event number
      that is specified in the driver. When this length is shorter than
      firmware expects setting event mask will fail and device becomes
      pretty useless. This issue was reported with bcm4339 firmware that

      sched: Fix cpu_active_mask/cpu_online_mask race

      There is a race condition in SMP bootup code, which may result
      in

          workqueue_cpu_up_callback()
      or
          kernel BUG at kernel/smpboot.c:135!

      It can be triggered with a bit of luck in Linux guests running
      on busy hosts.

      During the various CPU_ONLINE callbacks CPUn is online but not

      the scheduling of tasks on CPU0.

            rebind_workers()
              set_cpus_allowed_ptr()

        This call fails because it requires an active CPU; rebind_workers()
        ends with a warning:

          WARNING: CPU: 0 PID: 1 at kernel/workqueue.c:4418
          workqueue_cpu_up_callback()

        The ->wake_cpu of the unparked thread is not allowed, making a call
        to select_fallback_rq() necessary. Then, select_fallback_rq() cannot
        find an allowed, active CPU and promptly resets the allowed CPUs, so
        that the task in question ends up on CPU0.

        When those unparked tasks are eventually executed, they run
        immediately into a BUG:

          kernel BUG at kernel/smpboot.c:135!

      Just changing the order in which the online/active bits are set
      (and adding some memory barriers), would solve the two issues
      above. However, it would change the order of operations back to
      the one before commit 6acbfb96976f ("sched: Fix hotplug vs.
      set_cpus_allowed_ptr()"), thus, reintroducing that particular
      problem.

      Going further back into history, we have at least the following
      commits touching this topic:
      - commit 2baab4e90495 ("sched: Fix select_fallback_rq() vs 
cpu_active/cpu_online")
      - commit 5fbd036b552f ("sched: Cleanup cpu_active madness")

      Together, these give us the following non-working solutions:

        - secondary CPU sets active before online, because active is assumed to
          be a subset of online;

        - secondary CPU sets online before active, because the primary CPU
          assumes that an online CPU is also active;

        - secondary CPU sets online and waits for primary CPU to set active,
          because it might deadlock.

      Commit 875ebe940d77 ("powerpc/smp: Wait until secondaries are
      active & online") introduces an arch-specific solution to this
      arch-independent problem.

      Now, go for a more general solution without explicit waiting and
      simply set active twice: once on the secondary CPU after online
      was set and once on the primary CPU after online was seen.

      ARM: entry: ensure that IRQs are enabled when calling syscall_trace_exit()

      The audit code looks like it's been written to cope with being called
      with IRQs enabled.  However, it's unclear whether IRQs should be
      enabled or disabled when calling the syscall tracing infrastructure.

      Right now, sometimes we call this with IRQs enabled, and other times
      with IRQs disabled.  Opt for IRQs being enabled for consistency.

      ARM: entry: efficiency cleanups

      Make the "fast" syscall return path fast again.  The addition of IRQ
      tracing and context tracking has made this path grossly inefficient.
      We can do much better if these options are enabled if we save the
      syscall return code on the stack - we then don't need to save a bunch
      of registers around every single callout to C code.

      drivers/video/fbdev/vt8623fb: Use arch_phys_wc_add() and pci_iomap_wc()

      This driver uses the same area for MTRR as for the ioremap().

      Convert the driver from using the x86-specific MTRR code to the
      architecture-agnostic arch_phys_wc_add(). It will avoid MTRRs if
      write-combining is available. In order to take advantage of that
      also ensure the ioremapped area is requested as write-combining.

      There are a few motivations for this:

      a) Take advantage of PAT when available.

      b) Help bury MTRR code away, MTRR is architecture-specific and on
         x86 it is being replaced by PAT.

      c) Help with the goal of eventually using _PAGE_CACHE_UC over
         _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
         de33c442e titled "x86 PAT: fix performance drop for glx,
         use UC minus for ioremap(), ioremap_nocache() and
         pci_mmap_page_range()").

      The conversion done is expressed by the following Coccinelle
      SmPL patch, it additionally required manual intervention to
      address all the ifdeffery and removal of redundant things which
      arch_phys_wc_add() already addresses such as verbose message

      PCI: Add pci_iomap_wc() variants

      PCI BARs tell us whether prefetching is safe, but they don't say
      anything about write combining (WC). WC changes ordering rules
      and allows writes to be collapsed, so it's not safe in general
      to use it on a prefetchable region.

      Add pci_iomap_wc() and pci_iomap_wc_range() so drivers can take
      advantage of write combining when they know it's safe.

      On architectures that don't fully support WC, e.g., x86 without
      PAT, drivers for legacy framebuffers may get some of the benefit
      by using arch_phys_wc_add() in addition to pci_iomap_wc().  But
      arch_phys_wc_add() is unreliable and should be avoided in
      general.  On x86, it uses MTRRs, which are limited in number and
      size, so the results will vary based on driver loading order.

      The goals of adding pci_iomap_wc() are to:

      - Give drivers an architecture-independent way to use WC so they can stop
        using interfaces like mtrr_add() (on x86, pci_iomap_wc() uses
        PAT when available).

      - Move toward using _PAGE_CACHE_MODE_UC, not _PAGE_CACHE_MODE_UC_MINUS,
        on x86 on ioremap_nocache() (see de33c442ed2a ("x86 PAT: fix
        performance drop for glx, use UC minus for ioremap(), ioremap_nocache()
        and pci_mmap_page_range()").

      drivers/video/fbdev/gxt4500: Use pci_ioremap_wc_bar() to map framebuffer

      The driver doesn't use mtrr_add() or arch_phys_wc_add() but
      since we know the framebuffer is isolated already on an
      ioremap() we can take advantage of write combining for
      performance where possible.

      In this case there are a few motivations for this:

      a) Take advantage of PAT when available.

      b) Help with the goal of eventually using _PAGE_CACHE_UC over
         _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
         de33c442e titled "x86 PAT: fix performance drop for glx,
         use UC minus for ioremap(), ioremap_nocache() and
         pci_mmap_page_range()").

      drivers/video/fbdev/kyrofb: Use arch_phys_wc_add() and 
pci_ioremap_wc_bar()

      Convert the driver from using the x86-specific MTRR code to the
      architecture-agnostic arch_phys_wc_add(). It will avoid MTRR if
      write-combining is available, in order to take advantage of that
      also ensure the ioremapped area is requested as write-combining.

      There are a few motivations for this:

      a) Take advantage of PAT when available

      b) Help bury MTRR code away, MTRR is architecture-specific and on
         x86 it is being replaced by PAT.

      c) Help with the goal of eventually using _PAGE_CACHE_UC over
         _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
         de33c442e titled "x86 PAT: fix performance drop for glx,
         use UC minus for ioremap(), ioremap_nocache() and
         pci_mmap_page_range()")

      The conversion done is expressed by the following Coccinelle
      SmPL patch, it additionally required manual intervention to
      address all the ifdeffery and removal of redundant things which
      arch_phys_wc_add() already addresses such as verbose message

      x86/mm: Make kernel/check.c explicitly non-modular

      The Kconfig currently controlling compilation of this code is:

        arch/x86/Kconfig:config X86_CHECK_BIOS_CORRUPTION
        arch/x86/Kconfig:       bool "Check for low memory corruption"

      ...meaning that it currently is not being built as a module by
      anyone.

      Lets remove the couple traces of modularity so that when reading
      the code there is no doubt it is builtin-only.

      Since module_init translates to device_initcall in the
      non-modular case, the init ordering remains unchanged with this
      commit.

      backlight: tosa: Export I2C module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
      regardless of the mechanism that was used to register the device
      (i.e: OF or board code) and the table that is used later to match
      the driver with the device (i.e: I2C id table or OF match table).

      So drivers needs to export the I2C id table and this be built into
      the module or udev won't have the necessary information to autoload
      the needed driver module when the device is added.

      ALSA: hda - Refresh sysfs at snd_hda_codec_update_widgets()

      In the commit [fa4f18b4f402: ALSA: hda - Refresh widgets sysfs at
      probing Haswell+ HDMI codecs], snd_hdac_refresh_widget_sysfs() is
      explicitly called in the codec driver.  But this results in refreshing
      twice, as snd_hdac_refresh_widget_sysfs() itself calls
      snd_hdac_refresh_widgets() function.

      Instead, we can replace the call in snd_hda_codec_update_widgets()
      with snd_hdac_refresh_widget_sysfs().  This also fixes the missing
      sysfs update for ca0132, too.

      can: pcan_usb: don't provide CAN FD bittimings by non-FD adapters

      The CAN FD data bittiming constants are provided via netlink only when 
there
      are valid CAN FD constants available in priv->data_bittiming_const.

      Due to the indirection of pointer assignments in the peak_usb driver the
      priv->data_bittiming_const never becomes NULL - not even for non-FD 
adapters.

      The data_bittiming_const points to zero'ed data which leads to this result
      when running 'ip -details link show can0':

      35: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN mode DEFAULT group

      ALSA: hda - Fix path power activation

      The widget power-saving code tries to turn up/down the power of each
      widget in the I/O paths that are modified at each jack plug/unplug.
      The recent report revealed that the power activation leaves some
      widgets unpowered after plugging.  This is because
      snd_hda_activate_path() turns on path->active flag at the end of the
      function while the path power management is done before that.  Then
      it's regarded as if nothing is active, and the driver turns off the
      power.

      The fix is simply to set the flag at the beginning of the function,
      before trying to power up.

      ACPI: Decouple ACPI idle and ACPI processor drivers

      This patch introduces a new Kconfig symbol, ACPI_PROCESSOR_IDLE,
      which is auto selected by architectures which support the ACPI
      based C states for CPU Idle management.

      The processor_idle driver in its present form contains declarations
      specific to X86 and IA64. Since there are no reasonable defaults
      for other architectures e.g. ARM64, the driver is selected only for
      X86 or IA64.

      This helps in decoupling the ACPI processor_driver from the ACPI
      processor_idle driver which is useful for the upcoming alternative
      patchwork for controlling CPU Performance (CPPC) and CPU Idle (LPI).

      ACPI: Split out ACPI PSS from ACPI Processor driver

      The ACPI processor driver is currently tied too closely
      to the ACPI P-states (PSS) and other related constructs
      for controlling CPU performance.

      The newer ACPI specification (v5.1 onwards) introduces
      alternative methods to PSS. These new mechanisms are
      described within each ACPI Processor object and so they
      need to be scanned whenever a new Processor object is detected.
      This patch introduces a new Kconfig symbol to allow for
      finer configurability among the two options for controlling
      performance states. There is no change in functionality and
      the option is auto-selected by the architectures which support it.

      A future commit will introduce support for CPPC: A newer method of
      controlling CPU performance. The OS is not expected to support
      CPPC and PSS at the same time, so the Kconfig option lets us make
      the two mutually exclusive at compile time.

      This change initializes the PCC Mailbox earlier than

      processor driver interface. The CPPC probe requires the PCC

      ACPI / EC: Fix an issue caused by the serialized _Qxx evaluations

      It is proven that Windows evaluates _Qxx handlers in a parallel way. This
      patch follows this fact, splits _Qxx evaluations from the NOTIFY queue to
      form a separate queue, so that _Qxx evaluations can be queued up on
      different CPUs rather than being queued up on a CPU0 bound queue.
      Event handling related callbacks are also renamed and sorted in this 
patch.

      xfs: Fix file type directory corruption for btree directories

      Users have occasionally reported that file type for some directory
      entries is wrong. This mostly happened after updating libraries some
      libraries. After some debugging the problem was traced down to
      xfs_dir2_node_replace(). The function uses args->filetype as a file type
      to store in the replaced directory entry however it also calls
      xfs_da3_node_lookup_int() which will store file type of the current
      directory entry in args->filetype. Thus we fail to change file type of a
      directory entry to a proper type.

      Fix the problem by storing new file type in a local variable before
      calling xfs_da3_node_lookup_int().

      xfs: lockdep annotations throw warnings on non-debug builds

      SO, now if we enable lockdep without enabling CONFIG_XFS_DEBUG,
      the lockdep annotations throw a warning because the assert that uses
      the lockdep define is not built in:

not used [-Wunused-function]
          xfs_lockdep_subclass_ok(

      So now we need to create an ifdef mess to sort this all out, because

      CONFIG_XFS_WARNING=[y|n] and CONFIG_LOCKDEP=[y|n] appropriately.

      xfs: Fix uninitialized return value in xfs_alloc_fix_freelist()

      xfs_alloc_fix_freelist() can sometimes jump to out_agbp_relse
      without ever setting value of 'error' variable which is then
      returned. This can happen e.g. when pag->pagf_init is set but AG is
      for metadata and we want to allocate user data.

      Fix the problem by initializing 'error' to 0, which is the desired
      return value when we decide to skip this group.

      clk: rockchip: register pll mux before pll itself

      The structure is xin24m -> pll -> pll-mux (xin24m,pll,xin32k). The pll
      does have an init callback to make sure the boot-selected frequency is
      using the expected pll settings and resets the same frequency using
      the values provided in the driver if necessary.

      The setting itself also involves remuxing the pll-mux temporarily to
      the xin24m source to let the new pll rate settle. Until now this worked
      flawlessly, even when it had the flaw of accessing the mux settings
      before the mux actually got registered.

      With the recent clock-core conversions this flaw became apparent in
      null pointer dereference in
      [<c03fc400>] (clk_hw_get_num_parents) from [<c0400df0>] 
(clk_mux_get_parent+0x14/0xc8)
      [<c0400ddc>] (clk_mux_get_parent) from [<c040246c>] 
(rockchip_rk3066_pll_set_rate+0xd8/0x320)

      So to fix that, simply register the pll-mux before the pll, so that
      it will be fully initialized when the pll clock executes its init-
      callback and possibly touches the pll-mux clock.

      clk: Hi6220: add stub clock driver

      On Hi6220, there have some clocks which can use mailbox channel to send
      messages to power controller to change frequency; this includes CPU, GPU
      and DDR clocks.

      For dynamic frequency scaling, firstly need write the frequency value to
      SRAM region, and then send message to mailbox to trigger power controller
      to handle this requirement. This driver will use syscon APIs to pass SRAM
      memory region and use common mailbox APIs for channels accessing.

      This init driver will support cpu frequency change firstly.

      f2fs: fix to release inode correctly

      In following call stack, if unfortunately we lose all chances to truncate
      inode page in remove_inode_page, eventually we will add the nid allocated
      previously into free nid cache, this nid is with NID_NEW status and with
      NEW_ADDR in its blkaddr pointer:

       - f2fs_create
        - f2fs_add_link
         - __f2fs_add_link
          - init_inode_metadata
           - new_inode_page
            - new_node_page
             - set_node_addr(, NEW_ADDR)
           - f2fs_init_acl   failed
           - remove_inode_page  failed
        - handle_failed_inode
         - remove_inode_page  failed
         - iput
          - f2fs_evict_inode
           - remove_inode_page  failed
           - alloc_nid_failed   cache a nid with valid blkaddr: NEW_ADDR

      This may not only cause resource leak of previous inode, but also may 
cause
      incorrect use of the previous blkaddr which is located in NO.nid node 
entry
      when this nid is reused by others.

      This patch tries to add this inode to orphan list if we fail to truncate
      inode, so that we can obtain a second chance to release it in orphan
      recovery flow.

      batman-adv: Annotate deleting functions with external lock via lockdep

      Functions which use (h)list_del* are requiring correct locking when they
      operate on global lists. Most of the time the search in the list and the
      delete are done in the same function. All other cases should have it
      visible that they require a special lock to avoid race conditions.

      Lockdep asserts can be used to check these problem during runtime when the
      lockdep functionality is enabled.

      batman-adv: Fix gw_bandwidth calculation on 32 bit systems

      The TVLV for the gw_bandwidth stores everything as u32. But the
      gw_bandwidth reads the signed long which limits the maximum value to
      (2 ** 31 - 1) on systems with 4 byte long. Also the input value is always
      converted from either Mibit/s or Kibit/s to 100Kibit/s. This reduces the
      values even further when the user sets it via the default unit Kibit/s. It
      may even cause an integer overflow and end up with a value the user never
      intended.

      Instead read the values as u64, check for possible overflows, do the unit
      adjustments and then reduce the size to u32.

      batman-adv: Fix kerneldoc over 80 column lines

      Kerneldoc required single line documentation in the past (before 2009).
      Therefore, the 80 columns limit per line check of checkpatch was disabled
      for kerneldoc. But kerneldoc is not excluded anymore from it and 
checkpatch
      now enabled the check again.

      batman-adv: Replace C99 int types with kernel type

      (s|u)(8|16|32|64) are the preferred types in the kernel. The use of the

even

      In pfkey_sendmsg the net mutex is taken and then pfkey_broadcast takes
      the RCU lock.

      Since pfkey_broadcast takes the RCU lock the allocation argument is
      pointless since GFP_ATOMIC must be used between the rcu_read_{,un}lock.
      The one call outside of rcu can be done with GFP_KERNEL.

      This patch adds the basic code of FUJITSU Extended Socket
      Network Device driver.

      When "PNP0C02" is found in ACPI DSDT, it evaluates "_STR"
      to check if "PNP0C02" is for Extended Socket device driver
      and retrieves ACPI resource information. Then creates
      platform_device.

      perf tools: Add Intel PT support for decoding TRACESTOP packets

      A TRACESTOP packet is produced when an Intel PT trace enters a defined
      region of the address space at which point the tracing stops.

      This patch just adds decoder support.

      Support for specifying TRACESTOP regions is left until later.

      perf tools: Add Intel PT support for using CYC packets

      CYC packets are a new Intel PT feature.

      CYC packets provide even finer grain timestamp information than MTC and
      TSC packets.  A CYC packet contains the number of CPU cycles since the
      last CYC packet. Unlike MTC and TSC packets, CYC packets are only sent
      when another packet is also sent.

      Support for this feature is indicated by:

      /sys/bus/event_source/devices/intel_pt/caps/psb_cyc

      which contains "1" if the feature is supported and "0" otherwise.

      CYC packets can be requested using a PMU config term e.g. perf record -e
      intel_pt/cyc/u sleep 1

      The frequency of CYC packets can also be specified.  e.g. perf record -e
      intel_pt/cyc,cyc_thresh=2/u sleep 1

      CYC packets are not requested by default.

      Valid cyc_thresh values are given by:

      /sys/bus/event_source/devices/intel_pt/caps/cycle_thresholds

      which contains a hexadecimal value, the bits of which represent valid
      values e.g. bit 2 set means value 2 is valid.

      The value represents the minimum number of CPU cycles that must have
      passed before a CYC packet can be sent.  The number of CPU cycles is:

          2 ^ (value - 1)

      e.g. value 4 means 8 CPU cycles must pass before a CYC packet can be
      sent.  Note a CYC packet is still only sent when another packet is sent,
      not at, e.g. every 8 CPU cycles.

      If an invalid value is entered, the error message will give a list of
      valid values e.g.

          $ perf record -e intel_pt/cyc,cyc_thresh=15/u uname
          Invalid cyc_thresh for intel_pt. Valid values are: 0-12

      tools/perf/Documentation/intel-pt.txt is updated in a later patch as
      there are a number of new features being added.

      TSC packets.  A CYC packet contains the number of CPU cycles since the
      last CYC packet.

      This patch just adds decoder support.  The CPU frequency can be related
      to TSC using the Maximum Non-Turbo Ratio in combination with the CBR
      (core-to-bus ratio) packet.  However more accuracy is achieved by simply
      interpolating the number of cycles between other timing packets like MTC
      or TSC.  This patch takes the latter approach.

      New features have been added to Intel PT which include a number of new
      packet definitions.

      This patch adds packet definitions for new packets: TMA, MTC, CYC, VMCS,
      TRACESTOP and MNT.  Also another bit in PIP is defined.

      This patch only adds support for the definitions. Later patches add
      support for decoding TMA, MTC, CYC and TRACESTOP which is where those
      packets are explained.

      VMCS and the newly defined bit in PIP are used with virtualization which
      is not supported yet.  MNT is a maintenance packet which the decoder
      should ignore.

      perf tools: Add Intel PT support for PSB periods

      The PSB packet is a synchronization packet that provides a starting
      point for decoding or recovery from errors.

      This patch adds support for a new Intel PT feature that allows the
      frequency of PSB packets to be specified.

      Support for this feature is indicated by
      /sys/bus/event_source/devices/intel_pt/caps/psb_cyc which contains "1"
      if the feature is supported and "0" otherwise.

      The PSB period can be specified as a PMU config term e.g. perf record -e
      intel_pt/psb_period=2/u sleep 1

      The default value is 3 or the nearest lower value that is supported.  0
      is always supported.

      Valid values are given by:

      /sys/bus/event_source/devices/intel_pt/caps/psb_periods

      which contains a hexadecimal value, the bits of which represent valid
      values e.g. bit 2 set means value 2 is valid.

      The value is converted to the approximate number of trace bytes between
      PSB packets as:

        2 ^ (value + 11)

      e.g. value 3 means 16KiB bytes between PSBs

      If an invalid value is entered, the error message will give a list of
      valid values e.g.

        $ perf record -e intel_pt/psb_period=15/u uname
        Invalid psb_period for intel_pt. Valid values are: 0-5

      tools/perf/Documentation/intel-pt.txt is updated in a later patch as
      there are a number of new features being added.

      For more information about PSB periods refer to the Intel 64 and IA-32

      lib: scatterlist: add sg splitting function

      Sometimes a scatter-gather has to be split into several chunks, or sub
      scatter lists. This happens for example if a scatter list will be
      handled by multiple DMA channels, each one filling a part of it.

      A concrete example comes with the media V4L2 API, where the scatter list
      is allocated from userspace to hold an image, regardless of the
      knowledge of how many DMAs will fill it :
       - in a simple RGB565 case, one DMA will pump data from the camera ISP
         to memory
       - in the trickier YUV422 case, 3 DMAs will pump data from the camera
         ISP pipes, one for pipe Y, one for pipe U and one for pipe V

      For these cases, it is necessary to split the original scatter list into
      multiple scatter lists, which is the purpose of this patch.

      The guarantees that are required for this patch are :
       - the intersection of spans of any couple of resulting scatter lists is
         empty.
       - the union of spans of all resulting scatter lists is a subrange of
         the span of the original scatter list.
       - streaming DMA API operations (mapping, unmapping) should not happen
         both on both the resulting and the original scatter list. It's either
         the first or the later ones.
       - the caller is reponsible to call kfree() on the resulting
         scatterlists.

      PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI

      On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at
      function 1 doesn't work if it is powered on before the SATA controller at
      function 0.  The result is that PATA doesn't work after resume, and we
      print messages like this:

        pata_jmicron 0000:02:00.1: Refused to change power state, currently in 
D3
        irq 17: nobody cared (try booting with the "irqpoll" option)

      Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
      Asynchronous threads for resume_noirq").  Prior to that, we powered on
      the functions in order, so this problem shouldn't happen.

      e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
      solved the problem for JMicron 361 and 363 devices.  With async suspend
      disabled, we always power on function 0 before function 1.

      Barto then reported the same problem with a JMicron 368 (see comment #57 
in
      the bugzilla).

      Rather than extending the blacklist piecemeal, disable async suspend for
      all JMicron multi-function SATA/PATA/AHCI devices.

      This quirk could stay in the ahci and pata_jmicron drivers, but it's 
likely
      the problem will occur even if pata_jmicron isn't loaded until after the
      suspend/resume.  Making it a PCI quirk ensures that we'll preserve the
      power-on order even if the drivers aren't loaded.

      irqchip/imx-gpcv2: IMX GPCv2 driver for wakeup sources

      IMX7D contains a new version of GPC IP block (GPCv2). It has two major
      functions: power management and wakeup source management.

      When the system is in WFI (wait for interrupt) mode, the GPC block
      will be the first block on the platform to be activated and signaled.

      In normal wait mode during cpu idle, the system can be woken up by any
      enabled interrupts. In standby or suspend mode, the system can only be
      wokem up by the pre-defined wakeup sources.

      I.e. that finished progress bar behind the error window. It is not a
      problem when we end up redrawing the whole screen, but its ugly when
      we present such error windows, provide a TUI method so that code like
      the above may avoid this situation, as will be done with the annotation
      code in the next cset.

      mfd: max77686: Split out regulator part from the DT binding

      The Maxim MAX77686 PMIC is a multi-function device with regulators,
      clocks and a RTC. The DT bindings for the clocks are in a separate
      file but the bindings for the regulators are inside the mfd part.

      To make it consistent with the clocks portion of the binding and
      because is more natural to look for regulator bindings under the
      bindings/regulator sub-directory, split the regulator portion of
      the DT binding and add it as a separate file.

      The MAX77802 is a chip that contains regulators, 2 32kHz clocks,
      a RTC and an I2C interface to program the individual components.

      The are already DT bindings for the regulators and clocks and
      these reference to a bindings/mfd/max77802.txt file, that didn't
      exist, for the details about the PMIC.

      mfd: max77686: Use a generic name for the PMIC node in the example

      The ePAPR standard says that: "the name of a node should be somewhat
      generic, reflecting the function of the device and not its precise
      programming model."

      So, change the max77686 binding document example to use a generic
      node name instead of using the chip's name.

      mfd: Add MFD_CROS_EC dependencies

      The MFD_CROS_EC symbol select CHROME_PLATFORMS and CROS_EC_PROTO but
      that caused a Kconfig unmet direct dependencies warning since these
      symbols could only be selected for X86 || ARM.

      The fix it, the CHROME_PLATFORMS dependencies were relexed on commit
      d12bbcd3ea44 ("platform/chrome: Don't make CHROME_PLATFORMS depends
      on X86 || ARM") but that was found to be wrong and the correct fix
      is to add the needed dependencies to the MFD_CROS_EC config symbol.

      There are only x86 and ARM based Chromebooks so to avoid showing up
      the config option on unsupported platforms, make the symbol depend on
      these architectures. Also add a || COMPILE_TEST so it can have build
      coverage on other platforms.

      mfd: cros_ec: Remove CROS_EC_PROTO dependency for SPI and I2C drivers

      The ChromeOS EC SPI and I2C transport drivers depends on CROS_EC_PROTO
      but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends
      on is bad practice as it may lead to circular Kconfig dependencies.

      Since these drivers already depend on MFD_CROS_EC and that config option
      already selects CROS_EC_PROTO, there is no need to make them explicitly
      depend on CROS_EC_PROTO since that dependency is already met.

      crypto: caam - fix writing to JQCR_MS when using service interface

      Most significant part of JQCR (Job Queue Control Register) contains
      bits that control endianness: ILE - Immediate Little Endian,
      DWS - Double Word Swap.
      The bits are automatically set by the Job Queue Controller HW.

      Unfortunately these bits are cleared in SW when submitting descriptors
      via the register-based service interface.
      >From LS1021A:
      JQCR_MS = 08080100 - before writing: ILE | DWS | SRC (JR0)
      JQCR_MS = 30000100 - after writing: WHL | FOUR | SRC (JR0)

      This would cause problems on little endian caam for descriptors
      containing immediata data or double-word pointers.
      Currently there is no problem since the only descriptors ran through
      this interface are the ones that (un)instantiate RNG.

      PCI: Set MPS to match upstream bridge

      Firmware typically configures the PCIe fabric with a consistent Max 
Payload
      Size setting based on the devices present at boot.  A hot-added device
      typically has the power-on default MPS setting (128 bytes), which may not
      match the fabric.

      The previous Linux default, in the absence of any "pci=pcie_bus_*" 
options,
      was PCIE_BUS_TUNE_OFF, in which we never touch MPS, even for hot-added
      devices.

      Add a new default setting, PCIE_BUS_DEFAULT, in which we make sure every
      device's MPS setting matches the upstream bridge.  This makes it more
      likely that a hot-added device will work in a system with optimized MPS
      configuration.

      Note that if we hot-add a device that only supports 128-byte MPS, it still
      likely won't work because we don't reconfigure the rest of the fabric.
      Booting with "pci=pcie_bus_peer2peer" is a workaround for this because it
      sets MPS to 128 for everything.

      arm64: set MAX_MEMBLOCK_ADDR according to linear region size

      The linear region size of a 39-bit VA kernel is only 256 GB, which
      may be insufficient to cover all of system RAM, even on platforms
      that have much less than 256 GB of memory but which is laid out
      very sparsely.

      So make sure we clip the memory we will not be able to map before
      installing it into the memblock memory table, by setting
      MAX_MEMBLOCK_ADDR accordingly.

      of/fdt: make memblock maximum physical address arch configurable

      When parsing the memory nodes to populate the memblock memory
      table, we check against high and low limits and clip any memory
      that exceeds either one of them.

      However, for arm64, the high limit of (phys_addr_t)~0 is not very
      meaningful, since phys_addr_t is 64 bits (i.e., no limit) but there
      may be other constraints that limit the memory ranges that we can
      support.

      So rename MAX_PHYS_ADDR to MAX_MEMBLOCK_ADDR (for clarity) and only
      define it if the arch does not supply a definition of its own.

      supports switching SDHI signals between 3.3V and 1.8V nominal voltage,
      and the SD driver should do that when switching to and from UHS modes.

      Add a flag for pins that have configurable I/O voltage and SoC

      drm/i915: Allow parsing of variable size child device entries from VBT

      VBT version 196 increased the size of common_child_dev_config. The
      parser code assumed that the size of this structure would not change.

      The modified code now copies the amount needed based on the VBT version,
      and emits a debug message if the VBT version is unknown (too new); since
      the struct config block won't shrink in newer versions it should be
      harmless to copy the maximum known size in such cases, so that's what we
      do, but emitting the warning is probably sensible anyway.

      In the longer run it might make sense to modify the parser code to use a
      version/feature mapping, rather than hardcoding things like this, but
      for now the variants are fairly manageable.

      This fixes a regression introduced in

      route: fix breakage after moving lwtunnel state

      __recnt and related fields need to be in its own cacheline for performance

      broke that on 32bit archs, causing BUILD_BUG_ON in dst_hold to be 
triggered.

      This patch fixes the breakage by moving the lwtunnel state to the end of
      dst_entry on 32bit archs. Unfortunately, this makes it share the cacheline
      with __refcnt and may affect performance, thus further patches may be

      We fix three problems with the new link failover/synch implementation,

      tipc: fix stale link problem during synchronization

      Recent changes to the link synchronization means that we can now just
      drop packets arriving on the synchronizing link before the synch point
      is reached. This has lead to significant simplifications to the
      implementation, but also turns out to have a flip side that we need
      to consider.

      Under unlucky circumstances, the two endpoints may end up
      repeatedly dropping each other's packets, while immediately
      asking for retransmission of the same packets, just to drop
      them once more. This pattern will eventually be broken when
      the synch point is reached on the other link, but before that,
      the endpoints may have arrived at the retransmission limit
      (stale counter) that indicates that the link should be broken.
      We see this happen at rare occasions.

      The fix for this is to not ask for retransmissions when a link is in
      state LINK_SYNCHING. The fact that the link has reached this state
      means that it has already received the first SYNCH packet, and that it
      knows the synch point. Hence, it doesn't need any more packets until the
      other link has reached the synch point, whereafter it can go ahead and
      ask for the missing packets.

      However, because of the reduced traffic on the synching link that
      follows this change, it may now take longer to discover that the
      synch point has been reached. We compensate for this by letting all
      packets, on any of the links, trig a check for synchronization
      termination. This is possible because the packets themselves don't
      contain any information that is needed for discovering this condition.

      tipc: interrupt link synchronization when a link goes down

      When we introduced the new link failover/synch mechanism
      in commit 6e498158a827fd515b514842e9a06bdf0f75ab86
      ("tipc: move link synch and failover to link aggregation level"),
      we missed the case when the non-tunnel link goes down during the link
      synchronization period. In this case the tunnel link will remain in
      state LINK_SYNCHING, something leading to unpredictable behavior when
      the failover procedure is initiated.

      In this commit, we ensure that the node and remaining link goes
      back to regular communication state (SELF_UP_PEER_UP/LINK_ESTABLISHED)
      when one of the parallel links goes down. We also ensure that we don't
      re-enter synch mode if subsequent SYNCH packets arrive on the remaining
      link.

      tipc: eliminate risk of premature link setup during failover

      When a link goes down, and there is still a working link towards its
      destination node, a failover is initiated, and the failed link is not
      allowed to re-establish until that procedure is finished. To ensure
      this, the concerned link endpoints are set to state LINK_FAILINGOVER,
      and the node endpoints to NODE_FAILINGOVER during the failover period.

      However, if the link reset is due to a disabled bearer, the corres-
      ponding link endpoint is deleted, and only the node endpoint knows
      about the ongoing failover. Now, if the disabled bearer is re-enabled
      during the failover period, the discovery mechanism may create a new
      link endpoint that is ready to be established, despite that this is not
      permitted. This situation may cause both the ongoing failover and any
      subsequent link synchronization to fail.

      In this commit, we ensure that a newly created link goes directly to
      state LINK_FAILINGOVER if the corresponding node state is
      NODE_FAILINGOVER. This eliminates the problem described above.

      Furthermore, we tighten the criteria for which packets are allowed
      to end a failover state in the function tipc_node_check_state().
      By checking that the receiving link is up and running, instead of just
      checking that it is not in failover mode, we eliminate the risk that
      protocol packets from the re-created link may cause the failover to
      be prematurely terminated.

      ====================
      *** nps_enet fixups ***

      Change v2
      TX done is handled back with NAPI poll.

      Change v1
      This patch set is a bunch of fixes to make nps_enet work correctly with
      all platforms, i.e. real device, emulation system, and simulation system.
      The main trigger for this patch set was that in our emulation system
      the TX end interrupt is "edge-sensitive" and therefore we cannot use the
      cause register since it is not sticky.
      Also:
      TX is handled during HW interrupt context and not NAPI job.
      race with TX done was fixed.
      added acknowledge for TX when device is "level sensitive".
      enable drop of control frames which is not needed for regular usage.

      So most of this patch set is about TX handling, which is now more 
complete.

      The Kconfig for this driver is currently:

      config MV_XOR
              bool "Marvell XOR engine support"

      ...meaning that it currently is not being built as a module by anyone.
      Lets remove the modular code that is essentially orphaned, so that
      when reading the driver there is no doubt it is builtin-only.

      Since module_init translates to device_initcall in the non-modular
      case, the init ordering remains unchanged with this commit.

      We leave some tags like MODULE_AUTHOR for documentation purposes.
      Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

      synthesis time and influence the supported features of the instantiated
      peripheral, those options are represented as device-tree properties to
      allow the driver to behave accordingly.

      The peripheral has a zero latency architecture, which means it is possible
      to switch from one to the next descriptor without any delay. This is
      archived by having a internal queue which can hold multiple descriptors.
      The driver supports this, which means it will submit new descriptors
      directly to the hardware until the queue is full and not wait for a
      descriptor to complete before the next one is submitted. Interrupts are
      used for the descriptor queue flow control.

      Currently the driver supports SG, cyclic and interleaved slave DMA.

      controller. This is a soft peripheral used in FPGAs and the bindings
      describe how it is connected to the system (clock, interrupt, memory map)
      as well as the configuration options that were used when the peripheral 
was

      x86/asm/msr: Make wrmsrl() a function

      As of cf991de2f614 ("x86/asm/msr: Make wrmsrl_safe() a
      function"), wrmsrl_safe is a function, but wrmsrl is still a
      macro.  The wrmsrl macro performs invalid shifts if the value
      argument is 32 bits. This makes it unnecessarily awkward to
      write code that puts an unsigned long into an MSR.

      To make this work, syscall_init needs tweaking to stop passing
      a function pointer to wrmsrl.

      Some use of those functions were providing unitialized values to those

          #include <sys/stat.h>

          {
              assert(argc == 2);
              char buffer[256];
              int fd = open(argv[1], O_RDONLY|O_NOCTTY);
              assert(fd >= 0);
              assert(read(fd, buffer, 0) == 0);

      x86/apic: Fix fallout from x2apic cleanup

      In the recent x2apic cleanup I got two things really wrong:
      1) The safety check in __disable_x2apic which allows the function to
         be called unconditionally is backwards. The check is there to
         prevent access to the apic MSR in case that the machine has no
         apic. Though right now it returns if the machine has an apic and
         therefor the disabling of x2apic is never invoked.

      2) x2apic_disable() sets x2apic_mode to 0 after registering the local
         apic. That's wrong, because register_lapic_address() checks x2apic
         mode and therefor takes the wrong code path.

      This results in boot failures on machines with x2apic preenabled by
      BIOS and can also lead to an fatal MSR access on machines without
      apic.

      The solutions are simple:
      1) Correct the sanity check for apic availability
      2) Clear x2apic_mode _before_ calling register_lapic_address()

  commit 69786cdb379bbc6eab14cf2393c1abd879316e85
  Author: Andrey Ryabinin <ryabinin.a.a@xxxxxxxxx>
  Date:   Thu Aug 13 08:37:24 2015 +0300

      x86/kasan, mm: Introduce generic kasan_populate_zero_shadow()

      Introduce generic kasan_populate_zero_shadow(shadow_start,
      shadow_end). This function maps kasan_zero_page to the
      [shadow_start, shadow_end] addresses.

      This replaces x86_64 specific populate_zero_shadow() and will
      be used for ARM64 in follow on patches.

      The main changes from original version are:

       * Use p?d_populate*() instead of set_p?d()
       * Use memblock allocator directly instead of vmemmap_alloc_block()
       * __pa() instead of __pa_nodebug(). __pa() causes troubles
         iff we use it before kasan_early_init(). kasan_populate_zero_shadow()
         will be used later, so we ok with __pa() here.

      x86/asm/delay: Introduce an MWAITX-based delay with a configurable timer

      MWAITX can enable a timer and a corresponding timer value
      specified in SW P0 clocks. The SW P0 frequency is the same as
      TSC. The timer provides an upper bound on how long the
      instruction waits before exiting.

      This way, a delay function in the kernel can leverage that
      MWAITX timer of MWAITX.

      When a CPU core executes MWAITX, it will be quiesced in a
      waiting phase, diminishing its power consumption. This way, we
      can save power in comparison to our default TSC-based delays.

      A simple test shows that:

        $ cat /sys/bus/pci/devices/0000\:00\:18.4/hwmon/hwmon0/power1_acc
        $ sleep 10000s
        $ cat /sys/bus/pci/devices/0000\:00\:18.4/hwmon/hwmon0/power1_acc

      Results:

        * TSC-based default delay:      485115 uWatts average power
        * MWAITX-based delay:           252738 uWatts average power

      Thus, that's about 240 milliWatts less power consumption. The
      test method relies on the support of AMD CPU accumulated power
      algorithm in fam15h_power for which patches are forthcoming.

      x86/asm: Add MONITORX/MWAITX instruction support

      AMD Carrizo processors (Family 15h, Models 60h-6fh) added a new
      feature called MWAITX (MWAIT with extensions) as an extension to
      MONITOR/MWAIT.

      This new instruction controls a configurable timer which causes
      the core to exit wait state on timer expiration, in addition to
      "normal" MWAIT condition of reading from a monitored VA.

      Compared to MONITOR/MWAIT, there are minor differences in opcode
      and input parameters:

      MWAITX ECX[1]: enable timer if set
      MWAITX EBX[31:0]: max wait time expressed in SW P0 clocks ==
      TSC. The software P0 frequency is the same as the TSC frequency.

                      MWAIT                           MWAITX
      opcode          0f 01 c9           |            0f 01 fb
      ECX[0]                  value of RFLAGS.IF seen by instruction
      ECX[1]          unused/#GP if set  |            enable timer if set
      ECX[31:2]                     unused/#GP if set
      EAX                           unused (reserve for hint)
      EBX[31:0]       unused             |            max wait time (SW P0 == 
TSC)

                      MONITOR                         MONITORX
      opcode          0f 01 c8           |            0f 01 fa
      EAX                     (logical) address to monitor
      ECX                     #GP if not zero

      Max timeout = EBX/(TSC frequency)

      [media] videobuf2-core: Add it to device-drivers DocBook

      Most of the stuff at videobuf2-core are ok for adding it to
      DocBook.

      Two notes here:
      1) As videobuf2-core will be soon be changed, better to
         not spend too much efforts right now, as things will
         change soon;

      2) struct vb2_queue has a number of private elements that are
         documented. As Kernel nano documentation format handles
         "private:" arguments, we need to put them on a separate
         comment block or to remove. Keeping the comments is
         obviously better ;)

      KVM: PPC: Book3S: correct width in XER handling

      In 64 bit kernels, the Fixed Point Exception Register (XER) is a 64
      bit field (e.g. in kvm_regs and kvm_vcpu_arch) and in most places it is
      accessed as such.

      This patch corrects places where it is accessed as a 32 bit field by a
      64 bit kernel.  In some cases this is via a 32 bit load or store
      instruction which, depending on endianness, will cause either the
      lower or upper 32 bits to be missed.  In another case it is cast as a
      u32, causing the upper 32 bits to be cleared.

      This patch corrects those places by extending the access methods to
      64 bits.

      KVM: PPC: Book3S HV: Fix bug in dirty page tracking

      This fixes a bug in the tracking of pages that get modified by the
      guest.  If the guest creates a large-page HPTE, writes to memory
      somewhere within the large page, and then removes the HPTE, we only
      record the modified state for the first normal page within the large
      page, when in fact the guest might have modified some other normal
      page within the large page.

      To fix this we use some unused bits in the rmap entry to record the
      order (log base 2) of the size of the page that was modified, when
      removing an HPTE.  Then in kvm_test_clear_dirty_npages() we use that
      order to return the correct number of modified pages.

      The same thing could in principle happen when removing a HPTE at the
      host's request, i.e. when paging out a page, except that we never
      page out large pages, and the guest can only create large-page HPTEs
      if the guest RAM is backed by large pages.  However, we also fix
      this case for the sake of future-proofing.

      The reference bit is also subject to the same loss of information.  We
      don't make the same fix here for the reference bit because there isn't
      an interface for userspace to find out which pages the guest has
      referenced, whereas there is one for userspace to find out which pages
      the guest has modified.  Because of this loss of information, the
      kvm_age_hva_hv() and kvm_test_age_hva_hv() functions might incorrectly
      say that a page has not been referenced when it has, but that doesn't
      matter greatly because we never page or swap out large pages.

      KVM: PPC: Book3S HV: Fix race in reading change bit when removing HPTE

      The reference (R) and change (C) bits in a HPT entry can be set by
      hardware at any time up until the HPTE is invalidated and the TLB
      invalidation sequence has completed.  This means that when removing
      a HPTE, we need to read the HPTE after the invalidation sequence has
      completed in order to obtain reliable values of R and C.  The code
      in kvmppc_do_h_remove() used to do this.  However, commit 6f22bd3265fb
      ("KVM: PPC: Book3S HV: Make HTAB code LE host aware") removed the
      read after invalidation as a side effect of other changes.  This
      restores the read of the HPTE after invalidation.

      The user-visible effect of this bug would be that when migrating a
      guest, there is a small probability that a page modified by the guest
      and then unmapped by the guest might not get re-transmitted and thus
      the destination might end up with a stale copy of the page.

      KVM: PPC: Book3S HV: Implement dynamic micro-threading on POWER8

      This builds on the ability to run more than one vcore on a physical
      core by using the micro-threading (split-core) modes of the POWER8
      chip.  Previously, only vcores from the same VM could be run together,
      and (on POWER8) only if they had just one thread per core.  With the
      ability to split the core on guest entry and unsplit it on guest exit,
      we can run up to 8 vcpu threads from up to 4 different VMs, and we can
      run multiple vcores with 2 or 4 vcpus per vcore.

      Dynamic micro-threading is only available if the static configuration
      of the cores is whole-core mode (unsplit), and only on POWER8.

      To manage this, we introduce a new kvm_split_mode struct which is
      shared across all of the subcores in the core, with a pointer in the
      paca on each thread.  In addition we extend the core_info struct to
      have information on each subcore.  When deciding whether to add a
      vcore to the set already on the core, we now have two possibilities:
      (a) piggyback the vcore onto an existing subcore, or (b) start a new
      subcore.

      Currently, when any vcpu needs to exit the guest and switch to host
      virtual mode, we interrupt all the threads in all subcores and switch
      the core back to whole-core mode.  It may be possible in future to
      allow some of the subcores to keep executing in the guest while
      subcore 0 switches to the host, but that is not implemented in this
      patch.

      This adds a module parameter called dynamic_mt_modes which controls
      which micro-threading (split-core) modes the code will consider, as a
      bitmap.  In other words, if it is 0, no micro-threading mode is
      considered; if it is 2, only 2-way micro-threading is considered; if
      it is 4, only 4-way, and if it is 6, both 2-way and 4-way
      micro-threading mode will be considered.  The default is 6.

      With this, we now have secondary threads which are the primary thread
      for their subcore and therefore need to do the MMU switch.  These
      threads will need to be started even if they have no vcpu to run, so
      we use the vcore pointer in the PACA rather than the vcpu pointer to
      trigger them.

      It is now possible for thread 0 to find that an exit has been
      requested before it gets to switch the subcore state to the guest.  In
      that case we haven't added the guest's timebase offset to the
      timebase, so we need to be careful not to subtract the offset in the
      guest exit path.  In fact we just skip the whole path that switches
      back to host context, since we haven't switched to the guest context.

      KVM: PPC: Book3S HV: Make use of unused threads when running guests

      When running a virtual core of a guest that is configured with fewer
      threads per core than the physical cores have, the extra physical
      threads are currently unused.  This makes it possible to use them to
      run one or more other virtual cores from the same guest when certain
      conditions are met.  This applies on POWER7, and on POWER8 to guests
      with one thread per virtual core.  (It doesn't apply to POWER8 guests
      with multiple threads per vcore because they require a 1-1 virtual to
      physical thread mapping in order to be able to use msgsndp and the
      TIR.)

      The idea is that we maintain a list of preempted vcores for each
      physical cpu (i.e. each core, since the host runs single-threaded).
      Then, when a vcore is about to run, it checks to see if there are
      any vcores on the list for its physical cpu that could be
      piggybacked onto this vcore's execution.  If so, those additional
      vcores are put into state VCORE_PIGGYBACK and their runnable VCPU
      threads are started as well as the original vcore, which is called
      the master vcore.

      After the vcores have exited the guest, the extra ones are put back
      onto the preempted list if any of their VCPUs are still runnable and
      not idle.

      This means that vcpu->arch.ptid is no longer necessarily the same as
      the physical thread that the vcpu runs on.  In order to make it easier
      for code that wants to send an IPI to know which CPU to target, we
      now store that in a new field in struct vcpu_arch, called thread_cpu.

      KVM: PPC: Fix warnings from sparse

      When compiling the KVM code for POWER with "make C=1", sparse
      complains about functions missing proper prototypes and a 64-bit
      constant missing the ULL prefix. Let's fix this by making the
      functions static or by including the proper header with the
      prototypes, and by appending a ULL prefix to the constant
      PPC_MPPE_ADDRESS_MASK.

      x86/traps: Weaken context tracking entry assertions

      We were asserting that we were all the way in CONTEXT_KERNEL
      when exception handlers were called.  While having this be true
      is, I think, a nice goal (or maybe a variant in which we assert
      that we're in CONTEXT_KERNEL or some new IRQ context), we're not
      quite there.

      In particular, if an IRQ interrupts the SYSCALL prologue and the
      IRQ handler in turn causes an exception, the exception entry
      will be called in RCU IRQ mode but with CONTEXT_USER.

      This is okay (nothing goes wrong), but until we fix up the
      SYSCALL prologue, we need to avoid warning.

      f2fs: lookup neighbor extent nodes for merging later

      In __lookup_extent_tree_ret we will not try to find neighbor nodes if
      we find the target node, in this condition, we will lost the chance to
      merge the new mapping with exist extent node later.

      So our extent cache of inode will be fragmented after overwrite exist
      file, we can see the number of extent node increases intensively in
      following test case:

      dd if=/dev/zero of=/mnt/f2fs/4m bs=4K count=1024

      Extent Cache:
        - Hit Count: L1-1:0 L1-2:0 L2:0
        - Hit Ratio: 0% (0 / 3072)
        - Inner Struct Count: tree: 1, node: 1

      dd if=/dev/zero of=/mnt/f2fs/4m bs=4K count=1024 conv=notrunc

      Extent Cache:
        - Hit Count: L1-1:2048 L1-2:0 L2:0
        - Hit Ratio: 33% (2048 / 6144)
        - Inner Struct Count: tree: 1, node: 961

      After commit 0f825ee6e873 ("f2fs: add new interfaces for extent tree"),
      f2fs_init_extent_tree becomes the only caller of __insert_extent_tree, and
      in f2fs_init_extent_tree, we will only insert extent node in an empty

      This is because f2fs_map_blocks will return with no error when meeting
      a hole or preallocated block, the caller __get_data_block will map the
      uninitialized variable value to bh->b_blocknr.

      Unfortunately generic_block_bmap will neither check the return value of
      get_data() nor check mapping info of buffer_head, result in returning
      the random block address.

      After fixing the issue, our result shows correctly:

      file_pos   start_blk     end_blk        blks
             0           0           0         256

      f2fs: fix to update cached_en of extent tree properly

      In f2fs_lookup_extent_tree, et->cached_en was read and updated with only
      read lock held,
      it could cause __lookup_extent_tree within return entirely wrong
      extent_node, if other
      thread update et->cached_en just before __lookup_extent_tree return.

      However, there are two things about this patch that need to be noticed:
      1. It does no good to arrange the order of concurrent read/write, the 
result
      would still
      be random in such case.
      2. It's built on this assumption: the mix up of reads and writes on a 
single
      pointer would
      not make the pointer partially wrong at any time. Please let me know if 
I'm
      wrong, thx.

      mtd: dataflash: Export OF module alias information

      The SPI core currently reports the MODALIAS uevent as "spi:<modalias>"
      even for SPI devices that were registered by OF.

      That means the OF module alias exported by MODULE_OF_TABLE(of,...) is
      currently not used and user-space has no way to autoload this module.

      But it is still a good practice to add the OF module alias information
      into the kernel module even when it currently is unused so once the SPI
      core is changed to report a correct OF modalias uevent, module
      autoloading will be working for this driver.

      DRM - radeon: Don't link train DisplayPort on HPD until we get the dpcd

      Most of the time this isn't an issue since hotplugging an adaptor will
      trigger a crtc mode change which in turn, causes the driver to probe
      every DisplayPort for a dpcd. However, in cases where hotplugging
      doesn't cause a mode change (specifically when one unplugs a monitor
      from a DisplayPort connector, then plugs that same monitor back in
      seconds later on the same port without any other monitors connected), we
      never probe for the dpcd before starting the initial link training. What
      happens from there looks like this:

        - GPU has only one monitor connected. It's connected via
          DisplayPort, and does not go through an adaptor of any sort.

        - User unplugs DisplayPort connector from GPU.

        - Change in HPD is detected by the driver, we probe every
          DisplayPort for a possible connection.

        - Probe the port the user originally had the monitor connected
          on for it's dpcd. This fails, and we clear the first (and only
          the first) byte of the dpcd to indicate we no longer have a
          dpcd for this port.

        - User plugs the previously disconnected monitor back into the
          same DisplayPort.

        - radeon_connector_hotplug() is called before everyone else,
          and tries to handle the link training. Since only the first
          byte of the dpcd is zeroed, the driver is able to complete
          link training but does so against the wrong dpcd, causing it
          to initialize the link with the wrong settings.

        - Display stays blank (usually), dpcd is probed after the
          initial link training, and the driver prints no obvious
          messages to the log.

      In theory, since only one byte of the dpcd is chopped off (specifically,
      the byte that contains the revision information for DisplayPort), it's
      not entirely impossible that this bug may not show on certain monitors.
      For instance, the only reason this bug was visible on my ASUS PB238
      monitor was due to the fact that this monitor using the enhanced framing
      symbol sequence, the flag for which is ignored if the radeon driver
      thinks that the DisplayPort version is below 1.1.

      Convert the ac97_bus from legacy suspend/resume callbacks to dev_pm_ops.

      Since there isn't anything special to do at the bus level the bus driver
      does not have to implement any callbacks. The device driver core will
      automatically pick up and execute the device's PM ops.

      As there is only a single AC'97 driver implementing suspend and resume,
      update both the core and driver at the same time to avoid unnecessary code
      churn.

      While we are at it also drop the ifdefs around the suspend/resume 
functions

      spi: dw: Allow interface drivers to limit data I/O to word sizes

      The commit dd11444327ce ("spi: dw-spi: Convert 16bit accesses to 32bit
      accesses") changed all 16bit accesses in the DW_apb_ssi driver to 32bit.
      This, unfortunately, breaks data register access on picoXcell, where the
      DW IP needs data register accesses to be word accesses (all other
      accesses appear to be OK).

      This change introduces a new master variable to allow interface drivers
      to specify that 16bit data transfer I/O is required.  This change also
      introduces the ability to set this variable via device tree bindings in
      the MMIO interface driver.  Both the core and the MMIO interface driver
      default to the current 32bit behaviour.

      Before this change, on a picoXcell pc3x3:
       spi_master spi32766: interrupt_transfer: fifo overrun/underrun
       m25p80 spi32766.0: error -5 reading 9f
       m25p80: probe of spi32766.0 failed with error -5

      After this change:
       m25p80 spi32766.0: m25p40 (512 Kbytes)

      btrfs: fix compile when block cgroups are not enabled

      bio->bi_css and bio->bi_ioc don't exist when block cgroups are not on.
      This adds an ifdef around them.  It's not perfect, but our
      use of bi_ioc is being removed in the 4.3 merge window.

      The bi_css usage really should go into bio_clone, but I want to make
      sure that doesn't introduce problems for other bio_clone use cases.

      ARM: tegra: Fix AHB base address on Tegra20, Tegra30 and Tegra114

      Current base address is wrong by 0x04 bytes for AHB bus device as shown
      in dmesg:

        tegra-ahb 6000c004.ahb: incorrect AHB base address in DT data - 
enabling workaround

      To correct old DTBs, commit ce7a10b0ff3d ("ARM: 8334/1: amba: tegra-ahb:
      detect and correct bogus base address") checks for the low bit of the
      base address and removes theses 0x04 bytes at runtime.

      This patch fixes the original DTS, so upstream version doesn't need the
      workaround of the base address.

      As both addresses are valid, this patch doesn't break compatibility.

      Tested on tegra20-paz00 (aka ac100).

      use_single_rw currently reflects the capabilities of the connected
      device. The capabilities of the bus are currently missing for this
      variable.

      As there are read only and write only buses we need seperate values for
      use_single_rw to also reflect tha capabilities of the bus.

      This patch splits use_single_rw into use_single_read and
      use_single_write. The initialization is changed to check the
      configuration for use_single_rw and to check the capabilities of the
      used bus.

      I have a static checker that complains when we check for an upper bound

      the upper bound check seems not really required, so it is not a bug to

      ipvs: call rtnl_lock early

      When the sync damon is started we need to hold rtnl
      lock while calling ip_mc_join_group. Currently, we have
      a wrong locking order because the correct one is
      rtnl_lock->__ip_vs_mutex. It is implied from the usage
      of __ip_vs_mutex in ip_vs_dst_event() which is called
      under rtnl lock during NETDEV_* notifications.

      Fix the problem by calling rtnl_lock early only for the
      start_sync_thread call. As a bonus this fixes the usage
      __dev_get_by_name which was not called under rtnl lock.

      This patch actually extends and depends on commit 54ff9ef36bdf

      perf probe: Try to use symbol table if searching debug info failed

      A problem can occur in a statically linked perf when vmlinux can be found:

       # perf probe --add sys_epoll_pwait
       probe-definition(0): sys_epoll_pwait
       symbol:sys_epoll_pwait file:(null) line:0 offset:0 return:0 lazy:(null)

       An error occurred in debuginfo analysis (-2).
         Error: Failed to add events. Reason: No such file or directory (Code: 
-2)

      The reason is caused by libdw that, if libdw is statically linked, it
      can't load libebl_{arch}.so reliable.

      In this case it is still possible to get the address from
      /proc/kalksyms.  However, perf tries that only when libdw returns
      -EBADF.

      This patch gives it another chance to utilize symbol table, even if
      libdw returns an error code other than -EBADF.

      After applying this patch:

       # perf probe -nv --add sys_epoll_pwait
       probe-definition(0): sys_epoll_pwait
       symbol:sys_epoll_pwait file:(null) line:0 offset:0 return:0 lazy:(null)

       Writing event: p:probe/sys_epoll_pwait _text+2276672
         probe:sys_epoll_pwait (on sys_epoll_pwait)

       You can now use it in all perf tools, such as:

        perf record -e probe:sys_epoll_pwait -aR sleep 1

      Although libdw returns an error (Failed to get call frame), perf tries
      symbol table and finally gets correct address.

      perf tools: Initialize reference counts in map__clone()

      Map clone was written before we introduced reference counts for
      maps and dsos, so all that was needed was just a copy and then we
      would insert it into the new map_groups instance.

      Fix it by, after copying, initializing the map->refcnt, grabbing
      a struct dso refcount and resetting pointers that may be used
      to determine if a map, when deleted, is in a rb_tree.

      ARM: orion5x: fix legacy orion5x IRQ numbers

      Since v3.18, attempts to deliver IRQ0 are rejected, breaking orion5x.
      Fix this by increasing all interrupts by one, as did 5d6bed2a9c8b for
      dove. Also, force MULTI_IRQ_HANDLER for all orion platforms (including
      dove) as the specific handler is needed to shift back IRQ numbers by
      one.

      [gregory.clement@xxxxxxxxxxxxxxxxxx]: moved the select
      MULTI_IRQ_HANDLER from PLAT_ORION_LEGACY to ARCH_ORION5X as it broke
      the build for dove.

      perf tools: Add example call-graph script

      Add a script to produce a call-graph from data exported to a postgresql

      bq2415x_charger: Allow to load and use driver even if notify device is 
not registered yet

      Driver bq2415x_charger works also without notify power supply device for
      charger detection. But when charger detection is specified in DT, then
      bq2415x_charger refused to loaded with -EPROBE_DEFER.

      This patch rewrites code so that notify device for charger detection is
      checked when power supply event is received and not when registering power
      supply device. So this patch allows to use bq2415x_charger driver also 
when
      kernel is compiled without driver for notify power supply device.

      Now after this patch scheduled workqueue is called after 
INIT_DELAYED_WORK,
      so it also fix problem when scheduled workqueue was called before init.

      perf tools: Add Intel BTS support

      Intel BTS support fits within the new auxtrace infrastructure.  Recording 
is
      supporting by identifying the Intel BTS PMU, parsing options and setting 
up
      events.

      Decoding is supported by queuing up trace data by thread and then decoding
      synchronously delivering synthesized event samples into the session 
processing
      for tools to consume.

      crypto: skcipher - Add top-level skcipher interface

      This patch introduces the crypto skcipher interface which aims
      to replace both blkcipher and ablkcipher.

      It's very similar to the existing ablkcipher interface.  The
      main difference is the removal of the givcrypt interface.  In
      order to make the transition easier for blkcipher users, there
      is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place
      a request on the stack for synchronous transforms.

      arm64: entry: always restore x0 from the stack on syscall return

      We have a micro-optimisation on the fast syscall return path where we
      take care to keep x0 live with the return value from the syscall so that
      we can avoid restoring it from the stack. The benefit of doing this is
      fairly suspect, since we will be restoring x1 from the stack anyway
      (which lives adjacent in the pt_regs structure) and the only additional
      cost is saving x0 back to pt_regs after the syscall handler, which could
      be seen as a poor man's prefetch.

      More importantly, this causes issues with the context tracking code.

      The ct_user_enter macro ends up branching into C code, which is free to
      use x0 as a scratch register and consequently leads to us returning junk
      back to userspace as the syscall return value. Rather than special case
      the context-tracking code, this patch removes the questionable
      optimisation entirely.

      processing after it detected the issue.

      That is, code that found the issue reported the first problem, but
      because it did not exit out of the functions smoothly, it caused the
      other warning to appear and not only that, it later caused the SIGSEGV.

      perf tools: Fix Intel PT timestamp handling

      Events that don't sample the timestamp have a timestamp value of -1.

      Intel PT processing wasn't taking that into account.

      This is particularly noticeable with Intel BTS because timestamps are
      not requested by default.

      Then, if the conversion of -1 to TSC results in a small number, the
      processing is unaffected.

      However if the conversion results in a big number, then the data is
      processed prematurely before relevant sideband data like mmap events,
      which in turn results in samples with unknown dsos.

      Commiter note:

      Since BTS wasn't upstream, I split the patch to fold the BTS part with
      the patch introducing it, to avoid having this bug in the commit
      history. PT was already upstream, so this patch contains that part.

      perf tools: /proc/kcore requires CAP_SYS_RAWIO message too noisy

      The "/proc/kcore requires CAP_SYS_RAWIO" message comes up all the time
      for 'perf script' if vmlinux is not found and the user isn't root, even
      when the kernel is not being traced and even though the message is only
      really relevant for annotation.

      Change it to pr_debug and instead put a note in the message displayed if
      annotation is not possible.

      Also, the file being accessed might not be /proc/kcore.  Tools can be
      directed to a different location using the --kallsyms option in which
      case kcore is expected to be in the same directory.  Adjust the message
      so it is not misleading in that case.

      perf script: Fix segfault using --show-mmap-events

      Patch "perf script: Don't assume evsel position of tracking events"
      changed 'perf script' to use 'perf_evlist__id2evsel()'. That results
      in a segfault if there is more than 1 event and there are
      synthesized mmap events e.g.

        $ perf record -e cycles,instructions -p$$ sleep 1
        $ perf script --show-mmap-events
        Segmentation fault (core dumped)

      That happens because these synthesized events have an 'id' of zero
      which does not match any 'evsel'.

      Currently, these synthesized events use the sample type of the first
      evsel.

      Change 'perf_evlist__id2evsel()' to reflect that which also makes
      it consistent with 'perf_evlist__event2evsel()'.

      vfs: Test for and handle paths that are unreachable from their mnt_root

      In rare cases a directory can be renamed out from under a bind mount.
      In those cases without special handling it becomes possible to walk up
      the directory tree to the root dentry of the filesystem and down
      from the root dentry to every other file or directory on the filesystem.

      Like division by zero .. from an unconnected path can not be given
      a useful semantic as there is no predicting at which path component
      the code will realize it is unconnected.  We certainly can not match
      the current behavior as the current behavior is a security hole.

      Therefore when encounting .. when following an unconnected path
      return -ENOENT.

      - Add a function path_connected to verify path->dentry is reachable
        from path->mnt.mnt_root.  AKA to validate that rename did not do
        something nasty to the bind mount.

        To avoid races path_connected must be called after following a path
        component to it's next path component.

      The Hyper-V top-level functional specification states, that
      "algorithms should be resilient to sudden jumps forward or
      backward in the TSC value", this means that we should consider
      TSC as unstable. In some cases tsc tests are able to detect the
      instability, it was detected in 543 out of 646 boots in my
      testing:

       Measured 6277 cycles TSC warp between CPUs, turning off TSC clock.
       tsc: Marking TSC unstable due to check_tsc_sync_source failed

      This is, however, just a heuristic. On Hyper-V platform there
      are two good clocksources: MSR-based hyperv_clocksource and
      recently introduced TSC page.

      i_lock is only needed until __d_find_any_alias calls dget on the alias
      dentry.  After that the reference to new ensures that dentry_kill and
      d_delete will not remove the inode from the dentry, and remove the
      dentry from the inode->d_entry list.

      The inode i_lock came to be held over the the __d_move calls in
      d_splice_alias through a series of introduction of locks with
      increasing smaller scope.  First it was the dcache_lock, then
      it was the dcache_inode_lock, and finally inode->i_lock.

      Furthermore inode->i_lock is not held over any other calls
      to d_move or __d_move so it can not provide any meaningful
      rename protection.

      dcache: Handle escaped paths in prepend_path

      A rename can result in a dentry that by walking up d_parent
      will never reach it's mnt_root.  For lack of a better term
      I call this an escaped path.

      prepend_path is called by four different functions __d_path,
      d_absolute_path, d_path, and getcwd.

      __d_path only wants to see paths are connected to the root it passes
      in.  So __d_path needs prepend_path to return an error.

      d_absolute_path similarly wants to see paths that are connected to
      some root.  Escaped paths are not connected to any mnt_root so
      d_absolute_path needs prepend_path to return an error greater
      than 1.  So escaped paths will be treated like paths on lazily
      unmounted mounts.

      getcwd needs to prepend "(unreachable)" so getcwd also needs
      prepend_path to return an error.

      d_path is the interesting hold out.  d_path just wants to print
      something, and does not care about the weird cases.  Which raises
      the question what should be printed?

      Given that <escaped_path>/<anything> should result in -ENOENT I
      believe it is desirable for escaped paths to be printed as empty
      paths.  As there are not really any meaninful path components when
      considered from the perspective of a mount tree.

      So tweak prepend_path to return an empty path with an new error
      code of 3 when it encounters an escaped path.

      mm: fix potential data race in SyS_swapon

      While running KernelThreadSanitizer (ktsan) on upstream kernel with
      trinity, we got a few reports from SyS_swapon, here is one of them:

      Read of size 8 by thread T307 (K7621):
       [<     inlined    >] SyS_swapon+0x3c0/0x1850 SYSC_swapon 
mm/swapfile.c:2395
       [<ffffffff812242c0>] SyS_swapon+0x3c0/0x1850 mm/swapfile.c:2345
       [<ffffffff81e97c8a>] ia32_do_call+0x1b/0x25

      Looks like the swap_lock should be taken when iterating through the
      swap_info array on lines 2392 - 2401: q->swap_file may be reset to
      NULL by another thread before it is dereferenced for f_mapping.

      But why is that iteration needed at all?  Doesn't the claim_swapfile()
      which follows do all that is needed to check for a duplicate entry -
      FMODE_EXCL on a bdev, testing IS_SWAPFILE under i_mutex on a regfile?

      Well, not quite: bd_may_claim() allows the same "holder" to claim the
      bdev again, so we do need to use a different holder than "sys_swapon";
      and we should not replace appropriate -EBUSY by inappropriate -EINVAL.

      Index i was reused in a cpu loop further down: renamed cpu there.

      Netfilter updates for net-next

      This is second pull request includes the conflict resolution patch that
      resulted from the updates that we got for the conntrack template through
      kmalloc. No changes with regards to the previously sent 15 patches.

      The following patchset contains Netfilter updates for your net-next tree, 
they
      are:

      1) Rework the existing nf_tables counter expression to make it per-cpu.

      2) Prepare and factor out common packet duplication code from the TEE 
target so
         it can be reused from the new dup expression.

      3) Add the new dup expression for the nf_tables IPv4 and IPv6 families.

      4) Convert the nf_tables limit expression to use a token-based approach 
with
         64-bits precision.

      5) Enhance the nf_tables limit expression to support limiting at packet 
byte.
         This comes after several preparation patches.

      6) Add a burst parameter to indicate the amount of packets or bytes that 
can
         exceed the limiting.

      7) Add netns support to nfacct, from Andreas Schultz.

      8) Pass the nf_conn_zone structure instead of the zone ID in nf_tables to 
allow
         accessing more zone specific information, from Daniel Borkmann.

      9) Allow to define zone per-direction to support netns containers with
         overlapping network addressing, also from Daniel.

      10) Extend the CT target to allow setting the zone based on the skb->mark 
as a
         way to support simple mappings from iptables, also from Daniel.

      11) Make the nf_tables payload expression aware of the fact that VLAN 
offload
          may have removed a vlan header, from Florian Westphal.

      ARM: dts: UniPhier: fix PPI interrupt CPU mask of timer nodes

      This SoC is integrated with 4 Cortex-A9 cores.  The GIC bindings
      document says that the bits[15:8] of the 3rd cell of the interrupts
      property represents PPI interrupt CPU mask.  Because the timer
      interrupts are wired to all of the 4 cores, bits[15:8] should be set
      to 0xf.

      When getting translated from a downstream device tree that used slightly
      different DT bindings, these regulators got labeled with the
      "on-in-suspend" state, when they were actually supposed to be turned off
      for S3 suspend. This was harmless, but not intentional, AFAICT.

      Let's turn them off to get the optimal power state.

      route: move lwtunnel state to dst_entry

      Currently, the lwtunnel state resides in per-protocol data. This is
      a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice 
versa).
      The xmit function of the tunnel does not know whether the packet has been
      routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the
      lwtstate data to dst_entry makes such inter-protocol tunneling possible.

      As a bonus, this brings a nice diffstat.

      Instead of using the out-of-line EWMA calculation, use DECLARE_EWMA()

      PCI: Move MPS configuration check to pci_configure_device()

      Previously we checked for invalid MPS settings, i.e., a device with MPS
      different than its upstream bridge, in pcie_bus_detect_mps().  We only did
      this if the arch or hotplug driver called pcie_bus_configure_settings(),
      and then only if PCIe bus tuning was disabled (PCIE_BUS_TUNE_OFF).

      Move the MPS checking code to pci_configure_device(), so we do it in the
      pci_device_add() path for every device.

      irqchip/bcm2835: Refactor handle_IRQ() calls out of MAKE_HWIRQ

      For BCM2836, we want to chain into this IRQ chip from the root
      controller, and for chaining we need to do something else instead of
      handle_IRQ() once we have decoded the IRQ.

      Note that this changes the behavior a little bit: Previously for a
      non-shortcut IRQ, we'd loop reading and handling the second level IRQ
      status until it was cleared before returning to the loop reading the
      top level IRQ status (Note that the top level bit is just an OR of the
      low level bits).  For the expected case of just one interrupt to be
      handled, this was an extra register read, so we're down from 4 to 3
      reads.

      Update the DAX I/O path so that all operations that store data (I/O
      writes, zeroing blocks, punching holes, etc.) properly synchronize the
      stores to media using the PMEM API.  This ensures that the data DAX is

      pmem: add copy_from_iter_pmem() and clear_pmem()

      Add support for two new PMEM APIs, copy_from_iter_pmem() and
      clear_pmem().  copy_from_iter_pmem() is used to copy data from an
      iterator into a PMEM buffer.  clear_pmem() zeros a PMEM memory range.

      Both of these new APIs must be explicitly ordered using a wmb_pmem()
      function call and are implemented in such a way that the wmb_pmem()
      will make the stores to PMEM durable.  Because both APIs are unordered
      they can be called as needed without introducing any unwanted memory
      barriers.

      pmem, x86: clean up conditional pmem includes

      Prior to this change x86_64 used the pmem defines in
      arch/x86/include/asm/pmem.h, and UM used the default ones at the
      top of include/linux/pmem.h.  The inclusion or exclusion in linux/pmem.h
      was controlled by CONFIG_ARCH_HAS_PMEM_API, but the ones in asm/pmem.h
      were controlled by ARCH_HAS_NOCACHE_UACCESS.

      Instead, control them both with CONFIG_ARCH_HAS_PMEM_API so that it's
      clear that they are related and we don't run into the possibility where
      they are both included or excluded.  Also remove a bunch of stale
      function prototypes meant for UM in asm/pmem.h - these just conflicted
      with the inline defaults in linux/pmem.h and gave compile errors.

      extra layer of indirection and the redundant CONFIG_ARCH_HAS_PMEM_API
      check. Rename __arch_has_wmb_pmem() to arch_has_wmb_pmem() since we no
      longer have a wrapper, and just have arch_has_pmem_api() call the
      architecture specific arch_has_wmb_pmem() directly.

      spi: ti-qspi: use 128 bit transfer mode where possible

      TI QSPI has four 32 bit data regsiters which can be used to transfer 16
      bytes of data at once. The register group QSPI_SPI_DATA_REG_3,
      QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is
      treated as a single 128-bit word for shifting data in and out. The bit
      at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out
      in case of 128 bit transfer mode. Therefore the first byte to be written
      to flash should be at QSPI_SPI_DATA_REG_3[31-25] position.
      Instead of writing 1 byte at a time when interacting with spi-nor flash,
      make use of all the four registers so that 16 bytes can be transferred
      in one go. This reduces number of register writes and Word Complete
      interrupts for a given transfer message size, thereby increasing the
      write performance.

      Without this patch the raw flash write speed is ~100KB/s, with this
      patch the write speed increases to ~400 kB/s on DRA74 EVM.

      ARM/PCI, designware, xilinx: Use pci_scan_root_bus_msi()

      ARM previously stored the msi_controller pointer in its sysdata, struct
      pci_sys_data, and implemented pcibios_msi_controller() to retrieve it.
      That made PCI host controller drivers specific to ARM because they had to
      put the msi_controller pointer in the ARM-specific pci_sys_data.

      There is now a generic mechanism, pci_scan_root_bus_msi(), for giving the
      msi_controller pointer to the PCI core.  Use this for all ARM systems and
      for the DesignWare and Xilinx PCI host controller drivers.

      This removes an ARM dependency from the DesignWare, DRA7xx, EXYNOS, i.MX6,
      Keystone, Layerscape, SPEAr13xx, and Xilinx drivers.

      PCI: Add pci_scan_root_bus_msi()

      Add a pci_scan_root_bus_msi() interface so an arch can specify the MSI
      controller up front.  This removes the need for a pcibios callback to set
      the MSI controller later.

      This is not exported because I'd like to replace the variety of "scan root
      bus" interfaces with a single, more extensible interface that can handle
      the MSI controller, domain, pci_ops, resources, etc.  I hope this 
interface
      is temporary.

      ARM/PCI: Replace panic with WARN messages on failures

      In the ARM PCI bios32 layer, failures to dynamically allocate pci_sys_data
      for a PCI bus, or a PCI bus scan failure have to be considered serious
      warnings but they should not trigger a system panic so that at least the
      system is given a chance to be debugged.

      This patch replaces the panic statements with WARN() messages to improve
      error reporting in the ARM PCI bios32 layer.

      PCI: generic: Remove dependency on ARM-specific struct hw_pci

      The generic OF-based host controller driver uses pci_common_init_dev(),
      which is ARM-specific and requires the ARM struct hw_pci.  The part of
      pci_common_init_dev() that is needed is limited and can be done here
      without using hw_pci.

      Note that the ARM pcibios functions expect the PCI sysdata to be a pointer
      to a struct pci_sys_data.  Add a struct pci_sys_data as the first element
      in struct gen_pci so that when we use a gen_pci pointer as sysdata, it is
      also a pointer to a struct pci_sys_data.

      Create and scan the root bus directly without using the ARM
      pci_common_init_dev() interface.

      This patch adds a routine which checks the block address of newly 
allocated nid.
      If an nid has already allocated by other thread due to subtle data races, 
it

      So, it needs to check whether its block address was already allocated or 
not

      ARC: change some branchs to jumps to resolve linkage errors

      When kernel's binary becomes large enough (32M and more) errors
      may occur during the final linkage stage. It happens because
      the build system uses short relocations for ARC  by default.
      This problem may be easily resolved by passing -mlong-calls
      option to GCC to use long absolute jumps (j) instead of short
      relative branchs (b).

      But there are fragments of pure assembler code exist which use
      branchs in inappropriate places and cause a linkage error because
      of relocations overflow.

      First of these fragments is .fixup insertion in futex.h and
      unaligned.c. It inserts a code in the separate section (.fixup)
      with branch instruction. It leads to the linkage error when
      kernel becomes large.

      Second of these fragments is calling scheduler's functions
      (common kernel code) from entry.S of ARC's code. When kernel's
      binary becomes large it may lead to the linkage error because
      scheduler may occur far enough from ARC's code in the final
      binary.

      udf: Don't modify filesystem for read-only mounts

      When read-write mount of a filesystem is requested but we find out we
      can mount the filesystem only in read-only mode, we still modify
      LVID in udf_close_lvid(). That is both unnecessary and contrary to
      expectation that when we fall back to read-only mount we don't modify
      the filesystem.

      Make sure we call udf_close_lvid() only if we called udf_open_lvid() so
      that filesystem gets modified only if we verified we are allowed to
      write to it.

      genksyms: Duplicate function pointer type definitions segfault

      I noticed that genksyms will segfault when it sees duplicate function
      pointer type declaration when I placed the same function pointer
      definition in two separate headers in a local branch as an intermediate
      step of some refactoring. This can be reproduced by piping the following
      minimal test case into `genksyms -r /dev/null` or alternatively, putting
      it into a C file attempting a build:

      typedef int (*f)();
      typedef int (*f)();

      Attaching gdb to genksyms to understand this failure is useless without
      changing CFLAGS to emit debuginfo. Once you have debuginfo, you will
      find that the failure is that `char *s` was NULL and the program
      executed `while(*s)`. At which point, further debugging requires
      familiarity with compiler front end / parser development.

      What happens is that flex identifies the first instance of the token "f"
      as IDENT and the yacc parser adds it to the symbol table. On the second
      instance, flex will identify "f" as TYPE, which triggers an error case
      in the yacc parser. Given that TYPE would have been IDENT had it not
      been in the symbol table, the the segmentaion fault could be avoided by
      treating TYPE as IDENT in the affected rule.

      Some might consider placing identical function pointer type declarations
      in different headers to be poor style might consider a failure to be
      beneficial. However, failing through a segmentation fault makes the
      cause non-obvious and can waste the time of anyone who encounters it.

      final vmlinux.

      The problem is that the linker doesn't allow more specific submatches
      of a section name in a different linker script statement after the
      main match.

      So we need to move them all into one line. With that change
      .text.unlikely is at the end of everything again.

      I also moved .text.hot into the same statement though, even though
      that's not strictly needed.

      Avoid conflict with host definitions when cross-compiling

      Certain platforms (e. g. BSD-based ones) define some ELF constants
      according to host. This patch fixes problems with cross-building

      ARC: make futex_atomic_cmpxchg_inatomic() return bimodal

      Callers of cmpxchg_futex_value_locked() in futex code expect bimodal
      return value:
        !0 (essentially -EFAULT as failure)
         0 (success)

      Before this patch, the success return value was old value of futex,
      which could very well be non zero, causing caller to possibly take the
      failure path erroneously.

      Fix that by returning 0 for success

      (This fix was done back in 2011 for all upstream arches, which ARC
      obviously missed)

      ARCv2: Support IO Coherency and permutations involving L1 and L2 caches

      In case of ARCv2 CPU there're could be following configurations
      that affect cache handling for data exchanged with peripherals
      via DMA:
       [1] Only L1 cache exists
       [2] Both L1 and L2 exist, but no IO coherency unit
       [3] L1, L2 caches and IO coherency unit exist

      Current implementation takes care of [1] and [2].
      Moreover support of [2] is implemented with run-time check
      for SLC existence which is not super optimal.

      This patch introduces support of [3] and rework of DMA ops
      usage. Instead of doing run-time check every time a particular
      DMA op is executed we'll have 3 different implementations of
      DMA ops and select appropriate one during init.

      As for IOC support for it we need:
       [a] Implement empty DMA ops because IOC takes care of cache
           coherency with DMAed data
       [b] Route dma_alloc_coherent() via dma_alloc_noncoherent()
           This is required to make IOC work in first place and also
           serves as optimization as LD/ST to coherent buffers can be
           srviced from caches w/o going all the way to memory

      xen: allow more than 512 GB of RAM for 64 bit pv-domains

      64 bit pv-domains under Xen are limited to 512 GB of RAM today. The
      main reason has been the 3 level p2m tree, which was replaced by the
      virtual mapped linear p2m list. Parallel to the p2m list which is
      being used by the kernel itself there is a 3 level mfn tree for usage
      by the Xen tools and eventually for crash dump analysis. For this tree
      the linear p2m list can serve as a replacement, too. As the kernel
      can't know whether the tools are capable of dealing with the p2m list
      instead of the mfn tree, the limit of 512 GB can't be dropped in all
      cases.

      This patch replaces the hard limit by a kernel parameter which tells
      the kernel to obey the 512 GB limit or not. The default is selected by
      a configuration parameter which specifies whether the 512 GB limit
      should be active per default for domUs (domain save/restore/migration
      and crash dump analysis are affected).

      Memory above the domain limit is returned to the hypervisor instead of
      being identity mapped, which was wrong anyway.

      The kernel configuration parameter to specify the maximum size of a
      domain can be deleted, as it is not relevant any more.

      For 32 bit kernels adjust the memblock_reserve() parameters in order

      Some special pages containing interfaces to xen are being reserved
      implicitly only today. The memblock_reserve() call to reserve them is
      meant to reserve the p2m list supplied by xen. It is just reserving
      not only the p2m list itself, but some more pages up to the start of
      the xen built page tables.

      To be able to move the p2m list to another pfn range, which is needed
      for support of huge RAM, this memblock_reserve() must be split up to
      cover all affected reserved pages explicitly.

      The affected pages are:
      - start_info page
      - xenstore ring (might be missing, mfn is 0 in this case)
      - console ring (not for initial domain)

      xen: check memory area against e820 map

      Provide a service routine to check a physical memory area against the
      E820 map. The routine will return false if the complete area is RAM
      according to the E820 map and true otherwise.

      xen: split counting of extra memory pages from remapping

      Memory pages in the initial memory setup done by the Xen hypervisor
      conflicting with the target E820 map are remapped. In order to do this
      those pages are counted and remapped in xen_set_identity_and_remap().

      Split the counting from the remapping operation to be able to setup
      the needed memory sizes in time but doing the remap operation at a
      later time. This enables us to simplify the interface to
      xen_set_identity_and_remap() as the number of remapped and released
      pages is no longer needed here.

      Finally move the remapping further down to prepare relocating
      conflicting memory contents before the memory might be clobbered by
      xen_set_identity_and_remap(). This requires to not destroy the Xen
      E820 map when the one for the system is being constructed.

      xen: move static e820 map to global scope

      Instead of using a function local static e820 map in xen_memory_setup()
      and calling various functions in the same source with the map as a
      parameter use a map directly accessible by all functions in the source.

      xen: eliminate scalability issues from initial mapping setup

      Direct Xen to place the initial P->M table outside of the initial
      mapping, as otherwise the 1G (implementation) / 2G (theoretical)
      restriction on the size of the initial mapping limits the amount
      of memory a domain can be handed initially.

      As the initial P->M table is copied rather early during boot to
      domain private memory and it's initial virtual mapping is dropped,
      the easiest way to avoid virtual address conflicts with other
      addresses in the kernel is to use a user address area for the
      virtual address of the initial P->M table. This allows us to just
      throw away the page tables of the initial mapping after the copy
      without having to care about address invalidation.

      It should be noted that this patch won't enable a pv-domain to USE
      more than 512 GB of RAM. It just enables it to be started with a
      P->M table covering more memory. This is especially important for
      being able to boot a Dom0 on a system with more than 512 GB memory.

      xen: save linear p2m list address in shared info structure

      The virtual address of the linear p2m list should be stored in the
      shared info structure read by the Xen tools to be able to support
      64 bit pv-domains larger than 512 GB. Additionally the linear p2m
      list interface includes a generation count which is changed prior
      to and after each mapping change of the p2m list. Reading the
      generation count the Xen tools can detect changes of the mappings
      and re-read the p2m list eventually.

      xen/events: Support event channel rebind on ARM

      Currently, the event channel rebind code is gated with the presence of
      the vector callback.

      The virtual interrupt controller on ARM has the concept of per-CPU
      interrupt (PPI) which allow us to support per-VCPU event channel.
      Therefore there is no need of vector callback for ARM.

      Xen is already using a free PPI to notify the guest VCPU of an event.
      Furthermore, the xen code initialization in Linux (see
      arch/arm/xen/enlighten.c) is requesting correctly a per-CPU IRQ.

      Introduce new helper xen_support_evtchn_rebind to allow architecture
      decide whether rebind an event is support or not. It will always return
      true on ARM and keep the same behavior on x86.

      This is also allow us to drop the usage of xen_have_vector_callback
      entirely in the ARM code.

      memory between the kernel and the hypervisor has to be in big endian
      format. This exhibits as errors such as:

        irq: (null) didn't like hwirq-0x1000a00 to VIRQ16 mapping (rc=-22)
        hvsi_console_init: couldn't create irq mapping for 0x1000a00

      The data structures already have endian annotations, and sparse is
      generating numerous warnings based on those. This commit fixes all of
      them.

      leds/powernv: Add driver for PowerNV platform

      This patch implements LED driver for PowerNV platform using the existing
      generic LED class framework.

      PowerNV platform has below type of LEDs:
        - System attention
            Indicates there is a problem with the system that needs attention.
        - Identify
            Helps the user locate/identify a particular FRU or resource in the
            system.
        - Fault
            Indicates there is a problem with the FRU or resource at the
            location with which the indicator is associated.

      We register classdev structures for all individual LEDs detected on the
      system through LED specific device tree nodes. Device tree nodes specify
      what all kind of LEDs present on the same location code. It registers
      LED classdev structure for each of them.

      All the system LEDs can be found in the same regular path 
/sys/class/leds/.
      We don't use LED colors. We use LED node and led-types property to form
      LED classdev. Our LEDs have names in this format.

              <location_code>:<attention|identify|fault>

      Any positive brightness value would turn on the LED and a zero value would
      turn off the LED. The driver will return LED_FULL (255) for any turned on
      LED and LED_OFF (0) for any turned off LED.

      The platform level implementation of LED get and set state has been
      achieved through OPAL calls. These calls are made available for the
      driver by exporting from architecture specific codes.

      fbdev: fix cea_modes array size

      CEA defines 64 modes, indexed from 1 to 64. modedb has cea_modes arrays,
      which contains 64 entries. However, the code uses the CEA indices
      directly, i.e. the first mode is at cea_modes[1]. This means the array
      is one too short.

      This does not cause references to uninitialized memory as the code in
      fbmon only allows indexes up to 63, and the cea_modes does not contain
      an entry for the mode 64 so it could not be used in any case.

      However, the code contains a check 'if (idx > ARRAY_SIZE(cea_modes)',
      and while that check is a no-op as at that point idx cannot be >= 63, it
      upsets static checkers.

      Fix this by increasing the cea_array size to be 65, and change the code
      to allow mode 64.

      dmaengine: tegra-apb: Simplify locking for device using global pause

      Sparse reports the following with regard to locking in the
      tegra_dma_global_pause() and tegra_dma_global_resume() functions:

      drivers/dma/tegra20-apb-dma.c:362:9: warning: context imbalance in
        'tegra_dma_global_pause' - wrong count at exit
      drivers/dma/tegra20-apb-dma.c:366:13: warning: context imbalance in
        'tegra_dma_global_resume' - unexpected unlock

      The warning is caused because tegra_dma_global_pause() acquires a lock
      but does not release it. However, the lock is released by
      tegra_dma_global_resume(). These pause/resume functions are called in
      pairs and so it does appear to work.

      This global pause is used on early tegra devices that do not have an
      individual pause for each channel. The lock appears to be used to ensure
      that multiple channels do not attempt to assert/de-assert the global pause
      at the same time which could cause the DMA controller to be in the wrong
      paused state. Rather than locking around the entire code between the pause
      and resume, employ a simple counter to keep track of the global pause
      requests. By using a counter, it is only necessary to hold the lock when
      pausing and unpausing the DMA controller and hence, fixes the sparse
      warning.

      Please note that for devices that support individual channel pausing, the
      DMA controller lock is not held between pausing and unpausing the channel.
      Hence, this change will make the devices that use the global pause behave
      in the same way, with regard to locking, as those that don't.

      dmaengine: Stricter legacy checking in dma_request_slave_channel_compat()

      dma_request_slave_channel_compat() is meant for drivers that support
      both DT and legacy platform device based probing: if DT channel DMA
      setup fails, it will fall back to platform data based DMA channel setup,
      using hardcoded DMA channel IDs and a filter function.

      However, if the DTS doesn't provide a "dmas" property for the device,
      the fallback is also used. If the legacy filter function is not
      hardcoded in the DMA slave driver, but comes from platform data, it will
      be NULL. Then dma_request_slave_channel_compat() will succeed
      incorrectly, and return a DMA channel, as a NULL legacy filter function
      actually means "all channels are OK", not "do not match".

      Later, when trying to use that DMA channel, it will fail with:

          rcar-dmac e6700000.dma-controller: rcar_dmac_prep_slave_sg: bad 
parameter: len=1, id=-22

      To fix this, ensure that both the filter function and the DMA channel ID
      are not NULL before using the legacy fallback.

      Note that some DMA slave drivers can handle this failure, and will fall
      back to PIO.

      See also commit 056f6c87028544de ("dmaengine: shdma: Make dummy
      shdma_chan_filter() always return false"), which fixed the same issue
      for the case where shdma_chan_filter() is hardcoded in a DMA slave
      driver.

      cxl: Allow release of contexts which have been OPENED but not STARTED

      If we open a context but do not start it (either because we do not attempt
      to start it, or because it fails to start for some reason), we are left
      with a context in state OPENED. Previously, cxl_release_context() only
      allowed releasing contexts in state CLOSED, so attempting to release an
      OPENED context would fail.

      In particular, this bug causes available contexts to run out after some 
EEH
      failures, where drivers attempt to release contexts that have failed to
      start.

      Allow releasing contexts in any state with a value lower than STARTED, 
i.e.
      OPENED or CLOSED (we can't release a STARTED context as it's currently
      using the hardware, and we assume that contexts in any new states which 
may
      be added in future with a value higher than STARTED are also unsafe to
      release).

      macintosh/therm_windtunnel: Export OF module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      It would seem vrf_master_ifindex_rcu() can be called without RCU held in
      other contexts as well so introduce a new helper which acquires rcu and
      returns the ifindex.
      Also add curly braces around both the "if" and "else" parts as per the
      style guide.

      NFSv4: Enable delegated opens even when reboot recovery is pending

      Unlike the previous attempt, this takes into account the fact that
      we may be calling it from the recovery thread itself. Detect this
      by looking at what kind of open we're doing, and checking the state
      of the NFS_DELEGATION_NEED_RECLAIM if it turns out we're doing a
      reboot reclaim-type open.

      drm/layerscape: Add Freescale DCU DRM driver

      This patch add support for Two Dimensional Animation and Compositing
      Engine (2D-ACE) on the Freescale SoCs.

      2D-ACE is a Freescale display controller. 2D-ACE describes
      the functionality of the module extremely well its name is a value
      that cannot be used as a token in programming languages.
      Instead the valid token "DCU" is used to tag the register names and
      function names.

      The Display Controller Unit (DCU) module is a system master that
      fetches graphics stored in internal or external memory and displays
      them on a TFT LCD panel. A wide range of panel sizes is supported
      and the timing of the interface signals is highly configurable.
      Graphics are read directly from memory and then blended in real-time,
      which allows for dynamic content creation with minimal CPU
      intervention.

      The features:
      (1) Full RGB888 output to TFT LCD panel.
      (2) Blending of each pixel using up to 4 source layers
      dependent
      on size of panel.
      (3) Each graphic layer can be placed with one pixel resolution
      in either axis.
      (4) Each graphic layer support RGB565 and RGB888 direct colors
      without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct
      colors
      with an alpha channel and YUV422 format.
      (5) Each graphic layer support alpha blending with 8-bit
      resolution.
      This is a simplified version, only one primary plane, one
      framebuffer, one crtc, one connector and one encoder for TFT
      LCD panel.

      lwtunnel: Fix the sparse warnings in fib_encap_match

      When CONFIG_LWTUNNEL config is not enabled, the lwtstate_free() is not
      declared in lwtunnel.h at all. However, even in this case, the function
      is still referenced in fib_semantics.c so that there appears the
      following sparse warnings:

      net/ipv4/fib_semantics.c:553:17: error: undefined identifier 
'lwtstate_free'
        CC      net/ipv4/fib_semantics.o
        net/ipv4/fib_semantics.c: In function â??fib_encap_matchâ??:

        make[1]: *** [net/ipv4/fib_semantics.o] Error 1
        make: *** [net/ipv4/fib_semantics.o] Error 2

      To eliminate the error, we define an empty function for lwtstate_free()
      in lwtunnel.h when CONFIG_LWTUNNEL is disabled.

      nand: pxa3xx: Increase READ_ID buffer and make the size static

      The read ID count should be made as large as the maximum READ_ID size,
      so there's no need to have dynamic size. This commit sets the hardware
      maximum read ID count, which should be more than enough on all cases.
      Also, we get rid of the read_id_bytes, and use a macro instead.

      mtd: nand: pxa3xx-nand: fix random command timeouts

      When 2 commands are submitted in a row, and the second is very quick,
      the completion of the second command might never come. This happens
      especially if the second command is quick, such as a status read after
      an erase.

      The issue is that in the interrupt handler, the status bits are cleared
      after the new command is issued. There is a small temporal window where
      this happens :
       - the previous command has set the command done bit
       - the ready for a command bit is set
       - the handler submits the next command
         - just then, the command completes, and the command done bit is still
           set
       - the handler clears the "previous" command done bit
       - the handler exits

      In this flow, the "command done" of the next command will never trigger
      a new interrupt to finish the status command, as it was cleared for both
      commands.

      Fix this by clearing the status bit before submitting a new command.

      mtd: nand: pxa3xx_nand: fix early spurious interrupt

      When the nand is first probe, and upon the first command start, the
      status bits should be cleared before the interrupts are unmasked.

      The bug is tricky : if the bootloader left a status bit set, the
      unmasking of interrupts does trigger the interrupt handler before the
      first command is issued, blocking the good behavior of the nand.

      The same would happen if in pxa3xx_nand code flow a status bit is left,
      and then a command is started.

      arm: KVM: keep arm vfp/simd exit handling consistent with arm64

      After enhancing arm64 FP/SIMD exit handling, ARMv7 VFP exit branch is 
moved
      to guest trap handling. This allows us to keep exit handling flow between 
both
      architectures consistent.

      Btrfs: fix file read corruption after extent cloning and fsync

      If we partially clone one extent of a file into a lower offset of the
      file, fsync the file, power fail and then mount the fs to trigger log
      replay, we can get multiple checksum items in the csum tree that overlap
      each other and result in checksum lookup failures later. Those failures
      can make file data read requests assume a checksum value of 0, but they
      will not return an error (-EIO for example) to userspace exactly because
      the expected checksum value 0 is a special value that makes the read bio
      endio callback return success and set all the bytes of the corresponding
      page with the value 0x01 (at fs/btrfs/inode.c:__readpage_endio_check()).
      From a userspace perspective this is equivalent to file corruption
      because we are not returning what was written to the file.

      Details about how this can happen, and why, are included inline in the
      following reproducer test case for fstests and the comment added to
      tree-log.c.

      Btrfs: check if previous transaction aborted to avoid fs corruption

      While we are committing a transaction, it's possible the previous one is
      still finishing its commit and therefore we wait for it to finish first.
      However we were not checking if that previous transaction ended up getting
      aborted after we waited for it to commit, so we ended up committing the
      current transaction which can lead to fs corruption because the new
      superblock can point to trees that have had one or more nodes/leafs that
      were never durably persisted.
      The following sequence diagram exemplifies how this is possible:

                CPU 0

have now a superblock that points us
                                                                            to 
some root that uses eb X, which was
                                                                            
never written to disk

      In this scenario future attempts to read eb X from disk results in an
      error message like "parent transid verify failed on X wanted Y found Z".

      So fix this by aborting the current transaction if after waiting for the
      previous transaction we verify that it was aborted.

      block: Replace SG_GAPS with new queue limits mask

      The SG_GAPS queue flag caused checks for bio vector alignment against
      PAGE_SIZE, but the device may have different constraints. This patch
      adds a queue limits so a driver with such constraints can set to allow
      requests that would have been unnecessarily split. The new gaps check
      takes the request_queue as a parameter to simplify the logic around
      invoking this function.

      This new limit makes the queue flag redundant, so removing it and
      all usage. Device-mappers will inherit the correct settings through
      blk_stack_limits().

      btrfs: use __GFP_NOFAIL in alloc_btrfs_bio

      alloc_btrfs_bio relies on GFP_NOFS allocation when committing the
      transaction but this allocation context is rather weak wrt. reclaim
      capabilities. The page allocator currently tries hard to not fail these
      allocations if they are small (<=PAGE_ALLOC_COSTLY_ORDER) but it can
      still fail if the _current_ process is the OOM killer victim. Moreover
      there is an attempt to move away from the default no-fail behavior and
      allow these allocation to fail more eagerly. This would lead to:

      [   37.928625] kernel BUG at fs/btrfs/extent_io.c:4045

      which is clearly undesirable and the nofail behavior should be explicit
      if the allocation failure cannot be tolerated.

      btrfs: Remove useless condition in start_log_trans()

      Dan Carpenter <dan.carpenter@xxxxxxxxxx> reported a smatch warning
      for start_log_trans():
       fs/btrfs/tree-log.c:178 start_log_trans()
       warn: we tested 'root->log_root' before and it was 'false'

       fs/btrfs/tree-log.c
       147          if (root->log_root) {
       We test "root->log_root" here.
       ...

      Reason:
       Condition of:
       fs/btrfs/tree-log.c:178: if (!root->log_root) {
       is not necessary after commit: 7237f1833

       It caused a smatch warning, and no functionally error.

      Fix:
       Deleting above condition will make smatch shut up,
       but a better way is to do cleanup for start_log_trans()
       to remove duplicated code and make code more readable.

      Input: cros_ec_keyb - replace KEYBOARD_CROS_EC dependency

      The ChromeOS EC keyboard driver config depends on CROS_EC_PROTO but
      MFD_CROS_EC selects CROS_EC_PROTO instead. Mixing select and depends
      on is bad practice as it may lead to circular Kconfig dependencies.

      Since the platform device that is matched with the keyboard driver
      is registered by the ChromeOS EC mfd driver, KEYBOARD_CROS_EC really
      should depend on MFD_CROS_EC. And because this config option selects
      CROS_EC_PROTO, that dependency is met as well. So make the driver
      to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

      netfilter: bridge: fix IPv6 packets not being bridged with CONFIG_IPV6=n

      230ac490f7fba introduced a dependency to CONFIG_IPV6 which breaks bridging
      of IPv6 packets on a bridge with CONFIG_IPV6=n.

      Sysctl entry /proc/sys/net/bridge/bridge-nf-call-ip6tables defaults to 1,
      for this reason packets are handled by br_nf_pre_routing_ipv6(). When 
compiled
      with CONFIG_IPV6=n this function returns NF_DROP but should return 
NF_ACCEPT
      to let packets through.

      Change CONFIG_IPV6=n br_nf_pre_routing_ipv6() return value to NF_ACCEPT.

      Tested with a simple bridge with two interfaces and IPv6 packets trying
      to pass from host on left side to host on right side of the bridge.

      dmaengine: mv_xor: optimize performance by using a subset of the XOR 
channels

      Due to how async_tx behaves internally, having more XOR channels than
      CPUs is actually hurting performance more than it improves it, because
      memcpy requests get scheduled on a different channel than the XOR
      requests, but async_tx will still wait for the completion of the
      memcpy requests before scheduling the XOR requests.

      It is in fact more efficient to have at most one channel per CPU,
      which this patch implements by limiting the number of channels per
      engine, and the number of engines registered depending on the number
      of availables CPUs.

      Marvell platforms are currently available in one CPU, two CPUs and
      four CPUs configurations:

       - in the configurations with one CPU, only one channel from one
         engine is used.

       - in the configurations with two CPUs, only one channel from each
         engine is used (they are two XOR engines)

       - in the configurations with four CPUs, both channels of both engines
         are used.

      dmaengine: mv_xor: remove support for dmacap,* DT properties

      The only reason why we had dmacap,* properties is because back when
      DMA_MEMSET was supported, only one out of the two channels per engine
      could do a memset operation. But this is something that the driver
      already knows anyway, and since then, the DMA_MEMSET support has been
      removed.

      The driver is already well aware of what each channel supports and the
      one to one mapping between Linux specific implementation details (such
      as dmacap,interrupt enabling DMA_INTERRUPT) and DT properties is a
      good indication that these DT properties are wrong.

      Therefore, this commit simply gets rid of these dmacap,* properties,
      they are now ignored, and the driver is responsible for knowing the
      capabilities of the hardware with regard to the dmaengine subsystem
      expectations.

      dmaengine: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      dmaengine: imx-sdma: Add imx6sx platform support

      The new Solo X has more requirements for SDMA events. So it creates
      a event mux to remap most of event numbers in GPR (General Purpose
      Register). If we want to use SDMA support for those module who do
      not get the even number as default, we need to configure GPR first.

      Thus this patch adds this support of GPR event remapping configuration
      to the SDMA driver.

      kconfig: warn of unhandled characters in Kconfig commands

      In Kconfig, definitions of options take the following form:
      "<COMMAND> <PARAM> <PARAM> ...". COMMANDs and PARAMs are treated
      slightly different by the underlying parser.

      While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled
      characters") introduced a warning for unsupported characters around
      PARAMs, it does not cover situations where a COMMAND has additional
      characters before it.

      This change makes Kconfig emit a warning if superfluous characters
      are found before COMMANDs. As the 'help' statement sometimes is
      written as '---help---', the '-' character would now also be regarded
      as unhandled and generate a warning. To avoid that, '-' is added to
      the list of allowed characters, and the token '---help---' is included
      in the zconf.gperf file.

      s390/mm: simplify page table alloc/free code

      With the removal of the dynamic reallocation of page tables for
      KVM (see git commit 0b46e0a3ec0d7a04af6a091354f1b5e1b952d70a)
      the page table allocation / freeing code can be simplified.

      The page table free code can now use the alloc_pgste bit in the
      mm context to decide if a page table is 2K or 4K, there is no mix
      of different sized page tables anymore. This eliminates the need
      to use "page->_mapcount == 0" to check for 4K page table.

      Use the lower two bits in page->_mapcount to indicate which
      2K fragments of the 4K page are in use.

      As 31-bit support is gone, remove the two defines ALLOC_ORDER
      and FRAG_MASK and use the constants directly where appropriate.

      s390/hmcdrv: fix interrupt registration

      The z/VM driver sets bit "63-22" in control register zero to one in order
      to enable the CP Service interrupt (0x2603). However the irq subclass mask
      that normally corresponds to the CP Service interrupt is
      "63-54" (== "63-22-32").

      So it looks like the author read the documentation with the 32 bit sized
      cr0 register bit positions (== 22), but didn't realize that bit numbers
      change, if applied to a 64 bit register (== 54) due to the numbering
      scheme.

      Also use irq_subclass_register() instead if ctl_set_bit() since multiple
      services depend on the service signal subclass mask, which is the correct
      bit. This also explains why nobody noticed the bug, since the bit is 
always
      enabled anyway (e.g. pfault).

      powerpc/nvram: print no error when pstore backend is not nvram

      Pstore only supports one backend at a time. The preferred
      pstore backend is set by passing the pstore.backend=<name>
      argument to the kernel at boot time. Currently, while trying
      to register with pstore, nvram throws an error message even
      when "pstore.backend != nvram", which is unnecessary. This
      patch removes the error message in case "pstore.backend != nvram".

      libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option

      We currently register a platform device for e820 type-12 memory and
      register a nvdimm bus beneath it.  Registering the platform device
      triggers the device-core machinery to probe for a driver, but that
      search currently comes up empty.  Building the nvdimm-bus registration
      into the e820_pmem platform device registration in this way forces
      libnvdimm to be built-in.  Instead, convert the built-in portion of
      CONFIG_X86_PMEM_LEGACY to simply register a platform device and move the
      rest of the logic to the driver for e820_pmem, for the following
      reasons:

      1/ Letting e820_pmem support be a module allows building and testing
         libnvdimm.ko changes without rebooting

      2/ All the normal policy around modules can be applied to e820_pmem
         (unbind to disable and/or blacklisting the module from loading by
         default)

      3/ Moving the driver to a generic location and converting it to scan
         "iomem_resource" rather than "e820.map" means any other architecture 
can
         take advantage of this simple nvdimm resource discovery mechanism by
         registering a resource named "Persistent Memory (legacy)"

      NFSv4.1/pnfs: Fix a close/delegreturn hang when return-on-close is set

      The helper pnfs_roc() has already verified that we have no delegations,
      and no further open files, hence no outstanding I/O and it has marked
      all the return-on-close lsegs as being invalid.
      Furthermore, it sets the NFS_LAYOUT_RETURN bit, thus serialising the
      close/delegreturn with all future layoutget calls on this inode.

      The checks in pnfs_roc_drain() for valid layout segments are therefore
      redundant: those cannot exist until another layoutget completes.
      The other check for whether or not NFS_LAYOUT_RETURN is set, actually
      causes a hang, since we already know that we hold that flag.

      To fix, we therefore strip out all the functionality in pnfs_roc_drain()
      except the retrieval of the barrier state, and then rename the function
      accordingly.

      ====================
      Intel Wired LAN Driver Updates 2015-08-18

      This series contains updates to igb, e100, e1000e and ixgbe.

      Shota Suzuki provides a fix for a possible overflow in
      igb_set_interrupt_capability() which leads to an oops.  When changing the
      number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same
      manner as when initializing the igb driver.

      Vasily Averin provides a fix for a missing rtnl_unlock() for when we
      error out due to not being able to allocate memory for our queues.

      Stefan Assman provides a couple of fixes for igb/igbvf.  First changes
      the igb driver in probe to simply call igb_enable_sriov() instead of
      igb_sriov_reinit() since we are starting from scratch.  Then in igbvf,
      fix the driver where it does not clear the buffer_info->dma in all
      cases after calling dma_unmap_single(), which was found by changing the
      MTU twice.

      Richard Cochran implements the periodic output function using the
      programmable clock outputs available in i210 when possible, falling
      back to the target time for longer periods.

      Todd adds support for the Marvell PHY 1512 which is required for i354
      devices.  Then updates igb to make sure SR-IOV init uses the correct
      number of queues, since recent changes could result in the PF holding
      onto all of the queues.

      Alex Williamson provides a fix in the case where a guest OS does not
      support hot-unplug, so disable SR-IOV prior to unregister_netdev() to
      avoid the problem.

      Jia-Ju Bai provides several patches, first knocks some collecting dust
      off an old e100 driver to add a check to avoid a null pointer
      dereference.  Then cleans up a possible resource leak by releasing the
      skb buffer allocated when the e100_xmit_prepare() runs into an issue
      in the DMA mapping.  In igb, add a missing rtnl_unlock() for when we
      error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme().
      Provides a e1000e fix, based on suggestions from Alex Duyck to move
      head/tail register writing to e1000_configure_tx/rx() to avoid a
      possible null pointer dereference (similar to igb driver).  Lastly,
      fix a possible memory leak in igb_probe(), where the memory shadow_vfta
      allocated by kcalloc in igb_sw_init() is not freed.

      Mark simplifies port-specific macros for ixgbe by eliminating explicit
      comparisons with 0 and enclose formal parameters in parens to eliminate
      the risk of an operator precedence issue.

      lwtunnel: ip tunnel: fix multiple routes with different encap

      Currently, two routes going through the same tunnel interface are 
considered
      the same even when they are routed to a different host after 
encapsulation.
      This causes all routes added after the first one to have incorrect
      encapsulation parameters.

      This is nicely visible by doing:

        # ip r a 192.168.1.2/32 dev vxlan0 tunnel dst 10.0.0.2
        # ip r a 192.168.1.3/32 dev vxlan0 tunnel dst 10.0.0.3

      xfs: flush entire file on dio read/write to cached file

      Filesystems are responsible to manage file coherency between the page
      cache and direct I/O. The generic dio code flushes dirty pages over the
      range of a dio to ensure that the dio read or a future buffered read
      returns the correct data. XFS has generally followed this pattern,
      though traditionally has flushed and invalidated the range from the
      start of the I/O all the way to the end of the file. This changed after
      the following commit:

        7d4ea3ce xfs: use ranged writeback and invalidation for direct IO

      ... as the full file flush was no longer necessary to deal with the
      strange post-eof delalloc issues that were since fixed. Unfortunately,
      we have since received complaints about performance degradation due to
      the increased exclusive iolock cycles (which locks out parallel dio
      submission) that occur when a file has cached pages. This does not occur
      on filesystems that use the generic code as it also does not incorporate
      locking.

      The exclusive iolock is acquired any time the inode mapping has cached
      pages, regardless of whether they reside in the range of the I/O or not.
      If not, the flush/inval calls do no work and the lock was cycled for no
      reason.

      Under consideration of the cost of the exclusive iolock, update the dio
      read and write handlers to flush and invalidate the entire mapping when
      cached pages exist. In most cases, this increases the cost of the
      initial flush sequence but eliminates the need for further lock cycles
      and flushes so long as the workload does not actively mix direct and
      buffered I/O. This also more closely matches historical behavior and
      performance characteristics that users have come to expect.

      xfs: Fix xfs_attr_leafblock definition

      struct xfs_attr_leafblock contains 'entries' array which is declared
      with size 1 altough it can in fact contain much more entries. Since this
      array is followed by further struct members, gcc (at least in version
      4.8.3) thinks that the array has the fixed size of 1 element and thus
      may optimize away all accesses beyond the end of array resulting in
      non-working code. This problem was only observed with userspace code in
      xfsprogs, however it's better to be safe in kernel as well and have
      matching kernel and xfsprogs definitions.

      In the dir3 data block readahead function, use the regular read

      instead of directly calling only the spot-checking routine.  This
      prevents corrupted directory data blocks from being read into the

      xfs: stop holding ILOCK over filldir callbacks

      The recent change to the readdir locking made in 40194ec ("xfs:
      reinstate the ilock in xfs_readdir") for CXFS directory sanity was
      probably the wrong thing to do. Deep in the readdir code we
      can take page faults in the filldir callback, and so taking a page
      fault while holding an inode ilock creates a new set of locking
      issues that lockdep warns all over the place about.

      The locking order for regular inodes w.r.t. page faults is io_lock
      -> pagefault -> mmap_sem -> ilock. The directory readdir code now
      triggers ilock -> page fault -> mmap_sem. While we cannot deadlock
      at this point, it inverts all the locking patterns that lockdep
      normally sees on XFS inodes, and so triggers lockdep. We worked
      around this with commit 93a8614 ("xfs: fix directory inode iolock
      lockdep false positive"), but that then just moved the lockdep
      warning to deeper in the page fault path and triggered on security
      inode locks. Fixing the shmem issue there just moved the lockdep
      reports somewhere else, and now we are getting false positives from
      filesystem freezing annotations getting confused.

      Further, if we enter memory reclaim in a readdir path, we now get
      lockdep warning about potential deadlocks because the ilock is held
      when we enter reclaim. This, again, is different to a regular file
      in that we never allow memory reclaim to run while holding the ilock
      for regular files. Hence lockdep now throws
      ilock->kmalloc->reclaim->ilock warnings.

      Basically, the problem is that the ilock is being used to protect
      the directory data and the inode metadata, whereas for a regular
      file the iolock protects the data and the ilock protects the
      metadata. From the VFS perspective, the i_mutex serialises all
      accesses to the directory data, and so not holding the ilock for
      readdir doesn't matter. The issue is that CXFS doesn't access
      directory data via the VFS, so it has no "data serialisaton"
      mechanism. Hence we need to hold the IOLOCK in the correct places to
      provide this low level directory data access serialisation.

      The ilock can then be used just when the extent list needs to be
      read, just like we do for regular files. The directory modification
      code can take the iolock exclusive when the ilock is also taken,
      and this then ensures that readdir is correct excluded while
      modifications are in progress.

      xfs: clean up inode lockdep annotations

      Lockdep annotations are a maintenance nightmare. Locking has to be
      modified to suit the limitations of the annotations, and we're
      always having to fix the annotations because they are unable to
      express the complexity of locking heirarchies correctly.

      So, next up, we've got more issues with lockdep annotations for
      inode locking w.r.t. XFS_LOCK_PARENT:

        - lockdep classes are exclusive and can't be ORed together
          to form new classes.
        - IOLOCK needs multiple PARENT subclasses to express the
          changes needed for the readdir locking rework needed to
          stop the endless flow of lockdep false positives involving
          readdir calling filldir under the ILOCK.
        - there are only 8 unique lockdep subclasses available,
          so we can't create a generic solution.

      IOWs we need to treat the 3-bit space available to each lock type
      differently:

        - IOLOCK uses xfs_lock_two_inodes(), so needs:
                - at least 2 IOLOCK subclasses
                - at least 2 IOLOCK_PARENT subclasses
        - MMAPLOCK uses xfs_lock_two_inodes(), so needs:
                - at least 2 MMAPLOCK subclasses
        - ILOCK uses xfs_lock_inodes with up to 5 inodes, so needs:
                - at least 5 ILOCK subclasses
                - one ILOCK_PARENT subclass
                - one RTBITMAP subclass
                - one RTSUM subclass

      For the IOLOCK, split the space into two sets of subclasses.
      For the MMAPLOCK, just use half the space for the one subclass to
      match the non-parent lock classes of the IOLOCK.
      For the ILOCK, use 0-4 as the ILOCK subclasses, 5-7 for the
      remaining individual subclasses.

      Because they are now all different, modify xfs_lock_inumorder() to
      handle the nested subclasses, and to assert fail if passed an
      invalid subclass. Further, annotate xfs_lock_inodes() to assert fail
      if an invalid combination of lock primitives and inode counts are
      passed that would result in a lockdep subclass annotation overflow.

      xfs: swap leaf buffer into path struct atomically during path shift

      The node directory lookup code uses a state structure that tracks the
      path of buffers used to search for the hash of a filename through the
      leaf blocks. When the lookup encounters a block that ends with the
      requested hash, but the entry has not yet been found, it must shift over
      to the next block and continue looking for the entry (i.e., duplicate
      hashes could continue over into the next block). This shift mechanism
      involves walking back up and down the state structure, replacing buffers
      at the appropriate btree levels as necessary.

      When a buffer is replaced, the old buffer is released and the new buffer
      read into the active slot in the path structure. Because the buffer is
      read directly into the path slot, a buffer read failure can result in
      setting a NULL buffer pointer in an active slot. This throws off the
      state cleanup code in xfs_dir2_node_lookup(), which expects to release a
      buffer from each active slot. Instead, a BUG occurs due to a NULL
      pointer dereference:

        BUG: unable to handle kernel NULL pointer dereference at 
00000000000001e8

         ...

      This has been reproduced via a parallel fsstress and filesystem shutdown
      workload in a loop. The shutdown triggers the read error in the
      aforementioned codepath and causes the BUG in xfs_dir2_node_lookup().

      Update xfs_da3_path_shift() to update the active path slot atomically
      with respect to the caller when a buffer is replaced. This ensures that
      the caller always sees the old or new buffer in the slot and prevents
      the NULL pointer dereference.

      xfs: relocate sparse inode mount warning

      The sparse inodes feature is currently considered experimental. We warn
      at mount time from xfs_mount_validate_sb(). This function is part of the
      superblock verifier codepath, however, which means it could be invoked
      repeatedly on superblock reads or writes. This is currently only
      noticeable from userspace, where mkfs produces multiple warnings at
      format time.

      As mkfs warnings were not the intent of this change, relocate the mount
      time warning to xfs_fs_fill_super(), which is only invoked once and only
      in kernel space.

      Now that sb_uuid can be changed by the user, we cannot use this to
      validate the metadata blocks being recovered belong to this
      filesystem. We must check against the sb_meta_uuid as that will
      remain unchanged.

      There is a complication in this code - the superblock itself. We can
      not check the sb_meta_uuid unconditionally, as that may not be set
      on disk. Hence we must verify the superblock sb_uuid matches between
      the log record and the in-core superblock.

      xfs: set XFS_DA_OP_OKNOENT in xfs_attr_get

      It's entirely possible for userspace to ask for an xattr which
      does not exist.

      Normally, there is no problem whatsoever when we ask for such
      a thing, but when we look at an obfuscated metadump image
      on a debug kernel with selinux, we trip over this ASSERT in
      xfs_da3_path_shift():

              *result = -ENOENT;      /* we're out of our tree */
              ASSERT(args->op_flags & XFS_DA_OP_OKNOENT);

      It (more or less) only shows up in the above scenario, because
      xfs_metadump obfuscates attr names, but chooses names which
      keep the same hash value - and xfs_da3_node_lookup_int does:

              if (((retval == -ENOENT) || (retval == -ENOATTR)) &&
                  (blk->hashval == args->hashval)) {
                      error = xfs_da3_path_shift(state, &state->path, 1, 1,
                                                       &retval);

      IOWS, we only get down to the xfs_da3_path_shift() ASSERT
      if we are looking for an xattr which doesn't exist, but we
      find xattrs on disk which have the same hash, and so might be
      a hash collision, so we try the path shift.  When *that*
      fails to find what we're looking for, we hit the assert about
      XFS_DA_OP_OKNOENT.

      Simply setting XFS_DA_OP_OKNOENT in xfs_attr_get solves this
      rather corner-case problem with no ill side effects.  It's
      fine for an attr name lookup to fail.

      xfs: clean up root inode properly on mount failure

      The root inode is read as part of the xfs_mountfs() sequence and the
      reference is dropped in the event of failure after we grab the
      inode.  The reference drop doesn't necessarily free the inode,
      however. It marks it for reclaim and potentially kicks off the
      reclaim workqueue.  The workqueue is destroyed further up the error
      path, which means we are subject to crash if the workqueue job runs
      after this point or a memory leak which is identified if the
      xfs_inode_zone is destroyed (e.g., on module removal). Both of these
      outcomes are reproducible via manual instrumentation of a mount
      error after the root inode xfs_iget() call in xfs_mountfs().

      Update the xfs_mountfs() error path to cancel any potential reclaim
      work items and to run a synchronous inode reclaim if the root inode
      is marked for reclaim. This ensures that no jobs remain on the queue
      before it is destroyed and that the root inode is freed before the
      reclaim mechanism is torn down.

      first byte of each log record block before it is replaced with the lsn.
      The log record header has space for 32k worth of blocks. The version 2
      log adds new extended record headers for each additional 32k worth of
      blocks beyond what is supported by the record header.

      The log record checksum incorporates the log record header, the extended
      headers and the record payload. xlog_cksum() checksums the extended
      headers based on log->l_iclog_heads, which specifies the number of
      extended headers in a log record based on the log buffer size mount
      option. The log buffer size is variable, however, and thus means the
      checksum can be calculated differently based on how a filesystem is
      mounted. This is problematic if a filesystem crashes and recovery occurs
      on a subsequent mount using a different log buffer size. For example,
      crash an active filesystem that is mounted with the default (32k)
      logbsize, attempt remount/recovery using '-o logbsize=64k' and the mount
      fails on or warns about log checksum failures.

      To avoid this problem, update xlog_cksum() to calculate the checksum
      based on the size of the log buffer according to the log record. The
      size is already included in the h_size field of the log record header
      and thus is available at log recovery time. Extended log record headers
      are also only written when the log record is large enough to require
      them. This makes checksum calculation of log records consistent with the
      extended record header mechanism as well as how on-disk records are
      checksummed with various log buffer size mount options.

      xfs: fix broken icreate log item cancellation

      Inode cluster buffers are invalidated and cancelled when inode chunks
      are freed to notify log recovery that previous logged updates to the
      metadata buffer should be skipped. This ensures that log recovery does
      not overwrite buffers that might have already been reused.

      On v4 filesystems, inode chunk allocation and inode updates are logged
      via the cluster buffers and thus cancellation is easily detected via
      buffer cancellation items. v5 filesystems use the new icreate
      transaction, which uses logical logging and ordered buffers to log a
      full inode chunk allocation at once. The resulting icreate item often
      spans multiple inode cluster buffers.

      Log recovery checks for cancelled buffers when processing icreate log
      items, but it has a couple problems. First, it uses the full length of
      the inode chunk rather than the cluster size. Second, it uses the length
      in FSB units rather than BB units. Either of these problems prevent
      icreate recovery from identifying cancelled buffers and thus inode
      initialization proceeds unconditionally.

      Update xlog_recover_do_icreate_pass2() to iterate the icreate range in
      cluster sized increments and check each increment for cancellation.
      Since icreate is currently only used for the minimum atomic inode chunk
      allocation, we expect that either all or none of the buffers will be
      cancelled. Cancel the icreate if at least one buffer is cancelled to
      avoid making a bad situation worse by initializing a partial inode
      chunk, but detect such anomalies and warn the user.

      xfs: don't leave EFIs on AIL on mount failure

      Log recovery occurs in two phases at mount time. In the first phase,
      EFIs and EFDs are processed and potentially cancelled out. EFIs without
      EFD objects are inserted into the AIL for processing and recovery in the
      second phase. xfs_mountfs() runs various other operations between the
      phases and is thus subject to failure. If failure occurs after the first
      phase but before the second, pending EFIs sit on the AIL, pin it and
      cause the mount to hang.

      Update the mount sequence to ensure that pending EFIs are cancelled in
      the event of failure. Add a recovery cancellation mechanism to iterate
      the AIL and cancel all EFI items when requested. Plumb cancellation
      support through the log mount finish helper and update xfs_mountfs() to
      invoke cancellation in the event of failure after recovery has started.

      xfs: use EFI refcount consistently in log recovery

      The EFI is initialized with a reference count of 2. One for the EFI to
      ensure the item makes it to the AIL and one for the subsequently created
      EFD to release the EFI once the EFD is committed. Log recovery uses the
      EFI in a similar manner, but implements a hack to remove both references
      in one call once the EFD is handled.

      Update log recovery to use EFI reference counting in a manner consistent
      with the log. When an EFI is encountered during recovery, an EFI item is
      allocated and inserted to the AIL directly. Since the EFI reference is
      typically dropped when the EFI is unpinned and this is analogous with
      AIL insertion, drop the EFI reference at this point.

      When a corresponding EFD is encountered in the log, this indicates that
      the extents were freed, no processing is required and the EFI can be
      dropped. Update xlog_recover_efd_pass2() to simply drop the EFD
      reference at this point rather than open code the AIL removal and EFI
      free.

      Remaining EFIs (i.e., with no corresponding EFD) are processed in
      xlog_recover_finish(). An EFD transaction is allocated and the extents
      are freed, which transfers ownership of the EFI reference to the EFD
      item in the log.

      xfs: ensure EFD trans aborts on log recovery extent free failure

      Log recovery attempts to free extents with leftover EFIs in the AIL
      after initial processing. If the extent free fails (e.g., due to
      unrelated fs corruption), the transaction is cancelled, though it
      might not be dirtied at the time. If this is the case, the EFD does
      not abort and thus does not release the EFI. This can lead to hangs
      as the EFI pins the AIL.

      Update xlog_recover_process_efi() to log the EFD in the transaction
      before xfs_free_extent() errors are handled to ensure the
      transaction is dirty, aborts the EFD and releases the EFI on error.
      Since this is a requirement for EFD processing (and consistent with
      xfs_bmap_finish()), update the EFD logging helper to do the extent
      free and unconditionally log the EFD. This encodes the required EFD
      logging behavior into the helper and reduces the likelihood of
      errors down the road.

      xfs: fix efi/efd error handling to avoid fs shutdown hangs

      Freeing an extent in XFS involves logging an EFI (extent free
      intention), freeing the actual extent, and logging an EFD (extent
      free done). The EFI object is created with a reference count of 2:
      one for the current transaction and one for the subsequently created
      EFD. Under normal circumstances, the first reference is dropped when
      the EFI is unpinned and the second reference is dropped when the EFD
      is committed to the on-disk log.

      In event of errors or filesystem shutdown, there are various
      potential cleanup scenarios depending on the state of the EFI/EFD.
      The cleanup scenarios are confusing and racy, as demonstrated by the
      following test sequence:

        # mount $dev $mnt
        # fsstress -d $mnt -n 99999 -p 16 -z -f fallocate=1 \
                -f punch=1 -f creat=1 -f unlink=1 &
        # sleep 5
        # killall -9 fsstress; wait
        # godown -f $mnt
        # umount

      ... in which the final umount can hang due to the AIL being pinned
      indefinitely by one or more EFI items. This can occur due to several
      conditions. For example, if the shutdown occurs after the EFI is
      committed to the on-disk log and the EFD committed to the CIL, but
      before the EFD committed to the log, the EFD iop_committed() abort
      handler does not drop its reference to the EFI. Alternatively,
      manual error injection in the xfs_bmap_finish() codepath shows that
      if an error occurs after the EFI transaction is committed but before
      the EFD is constructed and logged, the EFI is never released from
      the AIL.

      Update the EFI/EFD item handling code to use a more straightforward
      and reliable approach to error handling. If an error occurs after
      the EFI transaction is committed and before the EFD is constructed,
      release the EFI explicitly from xfs_bmap_finish(). If the EFI
      transaction is cancelled, release the EFI in the unlock handler.

      Once the EFD is constructed, it is responsible for releasing the EFI
      under any circumstances (including whether the EFI item aborts due
      to log I/O error). Update the EFD item handlers to release the EFI
      if the transaction is cancelled or aborts due to log I/O error.
      Finally, update xfs_bmap_finish() to log at least one EFD extent to
      the transaction before xfs_free_extent() errors are handled to
      ensure the transaction is dirty and EFD item error handling is
      triggered.

      xfs: disentagle EFI release from the extent count

      Release of the EFI either occurs based on the reference count or the
      extent count. The extent count used is either the count tracked in
      the EFI or EFD, depending on the particular situation. In either
      case, the count is initialized to the final value and thus always
      matches the current efi_next_extent value once the EFI is completely
      constructed.  For example, the EFI extent count is increased as the
      extents are logged in xfs_bmap_finish() and the full free list is
      always completely processed. Therefore, the count is guaranteed to
      be complete once the EFI transaction is committed. The EFD uses the
      efd_nextents counter to release the EFI. This counter is initialized
      to the count of the EFI when the EFD is created. Thus the EFD, as
      currently used, has no concept of partial EFI release based on
      extent count.

      Given that the EFI extent count is always released in whole, use of
      the extent count for reference counting is unnecessary. Remove this
      level of the API and release the EFI based on the core reference
      count. The efi_next_extent counter remains because it is still used
      to track the slot to log the next extent to free.

      blkcg: use CGROUP_WEIGHT_* scale for io.weight on the unified hierarchy

      cgroup is trying to make interface consistent across different
      controllers.  For weight based resource control, the knob should have
      the range [1, 10000] and default to 100.  This patch updates
      cfq-iosched so that the weight range conforms.  The internal
      calculations have enough range and the widening of the weight range
      shouldn't cause any problem.

      * blkcg_policy->cpd_bind_fn() is added.  If present, this is invoked
        when blkcg is attached to a hierarchy.

      * cfq_cpd_init() is updated to use the new default value on the
        unified hierarchy.

      * cfq_cpd_bind() callback is implemented to clear per-blkg configs and
        apply the default config matching the hierarchy type.

      * cfqd->root_group->[leaf_]weight initialization in cfq_init_queue()
        is moved into !CONFIG_CFQ_GROUP_IOSCHED block.  cfq_cpd_bind() is
        now responsible for initializing the initial weights when blkcg is
        enabled.

      blkcg: implement interface for the unified hierarchy

      blkcg interface grew to be the biggest of all controllers and
      unfortunately most inconsistent too.  The interface files are
      inconsistent with a number of cloes duplicates.  Some files have
      recursive variants while others don't.  There's distinction between
      normal and leaf weights which isn't intuitive and there are a lot of
      stat knobs which don't make much sense outside of debugging and expose
      too much implementation details to userland.

      In the unified hierarchy, everything is always hierarchical and
      internal nodes can't have tasks rendering the two structural issues
      twisting the current interface.  The interface has to be updated in a
      significant anyway and this is a good chance to revamp it as a whole.
      This patch implements blkcg interface for the unified hierarchy.

      * (from a previous patch) blkcg is identified by "io" instead of
        "blkio" on the unified hierarchy.  Given that the whole interface is
        updated anyway, the rename shouldn't carry noticeable conversion
        overhead.

      * The original interface consisted of 27 files is replaced with the
        following three files.

        blkio.stat      : per-blkcg stats
        blkio.weight    : per-cgroup and per-cgroup-queue weight settings
        blkio.max       : per-cgroup-queue bps and iops max limits

      Documentation/cgroups/unified-hierarchy.txt updated accordingly.

      v2: blkcg_policy->dfl_cftypes wasn't removed on
          blkcg_policy_unregister() corrupting the cftypes list.  Fixed.

      Currently, blkg_conf_prep() expects input to be of the following form

      where BODY_STR is an arbitrary string.  blkg_conf_ctx->v is replaced
      with ->body which is a char pointer pointing to the start of BODY_STR.
      Parsing of the body is moved to blkg_conf_prep()'s callers.

      To allow using, for example, strsep() on blkg_conf_ctx->val, it is a

      blkcg: rename subsystem name from blkio to io

      blkio interface has become messy over time and is currently the
      largest.  In addition to the inconsistent naming scheme, it has
      multiple stat files which report more or less the same thing, a number
      of debug stat files which expose internal details which shouldn't have
      been part of the public interface in the first place, recursive and
      non-recursive stats and leaf and non-leaf knobs.

      Both recursive vs. non-recursive and leaf vs. non-leaf distinctions
      don't make any sense on the unified hierarchy as only leaf cgroups can
      contain processes.  cgroups is going through a major interface
      revision with the unified hierarchy involving significant fundamental
      usage changes and given that a significant portion of the interface
      doesn't make sense anymore, it's a good time to reorganize the
      interface.

      As the first step, this patch renames the external visible subsystem
      name from "blkio" to "io".  This is more concise, matches the other
      two major subsystem names, "cpu" and "memory", and better suited as
      blkcg will be involved in anything writeback related too whether an
      actual block device is involved or not.

      As the subsystem legacy_name is set to "blkio", the only userland
      visible change outside the unified hierarchy is that blkcg is reported
      as "io" instead of "blkio" in the subsystem initialized message during
      boot.  On the unified hierarchy, blkcg now appears as "io".

      blkcg: reduce stack usage of blkg_rwstat_recursive_sum()

      The recent percpu conversion of blkg_rwstat triggered the following
      warning in certain configurations.

       block/blk-cgroup.c:654:1: warning: the frame size of 1360 bytes is 
larger than 1024 bytes

      This is because blkg_rwstat now contains four percpu_counter which can
      be pretty big depending on debug options although it shouldn't be a
      problem in production configs.  This patch removes one of the two
      local blkg_rwstat variables used by blkg_rwstat_recursive_sum() to
      reduce stack usage.

      blkcg: remove cfqg_stats->sectors

      cfq_stats->sectors is a blkg_stat which keeps track of the total
      number of sectors serviced; however, this can be trivially calculated
      from blkcg_gq->stat_bytes.  The only thing necessary is adding up
      READs and WRITEs and then dividing by sector size.

      Remove cfqg_stats->sectors and make cfq print "sectors" and
      "sectors_recursive" from stat_bytes.

      While this is a bit more code, it removes duplicate stat allocations
      and updates and ensures that the reported stats stay in tune with each
      other.

      blkcg: move io_service_bytes and io_serviced stats into blkcg_gq

      Currently, both cfq-iosched and blk-throttle keep track of
      io_service_bytes and io_serviced stats.  While keeping track of them
      separately may be useful during development, it doesn't make much
      sense otherwise.  Also, blk-throttle was counting bio's as IOs while
      cfq-iosched request's, which is more confusing than informative.

      This patch adds ->stat_bytes and ->stat_ios to blkg (blkcg_gq),
      removes the counterparts from cfq-iosched and blk-throttle and let
      them print from the common blkg counters.  The common counters are
      incremented during bio issue in blkcg_bio_issue_check().

      The outputs are still filtered by whether the policy has
      blkg_policy_data on a given blkg, so cfq's output won't show up if it
      has never been used for a given blkg.  The only times when the outputs
      would differ significantly are when policies are attached on the fly
      or elevators are switched back and forth.  Those are quite exceptional
      operations and I don't think they warrant keeping separate counters.

      v3: Update blkio-controller.txt accordingly.

      v2: Account IOs during bio issues instead of request completions so
          that bio-based drivers can be handled the same way.

      blkcg: make blkcg_[rw]stat per-cpu

      blkcg_[rw]stat are used as stat counters for blkcg policies.  It isn't
      per-cpu by itself and blk-throttle makes it per-cpu by wrapping around
      it.  This patch makes blkcg_[rw]stat per-cpu and drop the ad-hoc
      per-cpu wrapping in blk-throttle.

      * blkg_[rw]stat->cnt is replaced with cpu_cnt which is struct
        percpu_counter.  This makes syncp unnecessary as remote accesses are
        handled by percpu_counter itself.

      * blkg_[rw]stat_init() can now fail due to percpu allocation failure
        and thus are updated to return int.

      * percpu_counters need explicit freeing.  blkg_[rw]stat_exit() added.

      * As blkg_rwstat->cpu_cnt[] can't be read directly anymore, reading
        and summing results are stored in ->aux_cnt[] instead.

      * Custom per-cpu stat implementation in blk-throttle is removed.

      This makes all blkcg stat counters per-cpu without complicating policy
      implmentations.

      blkcg: add blkg_[rw]stat->aux_cnt and replace cfq_group->dead_stats with 
it

      cgroup stats are local to each cgroup and doesn't propagate to
      ancestors by default.  When recursive stats are necessary, the sum is
      calculated over all the descendants.  This initially was for backward
      compatibility to support both group-local and recursive stats but this
      mode of operation makes general sense as stat update is much hotter
      thafn reporting those stats.

      This however ends up losing recursive stats when a child is removed.
      To work around this, cfq-iosched adds its stats to its parent
      cfq_group->dead_stats which is summed up together when calculating
      recursive stats.

      It's planned that the core stats will be moved to blkcg_gq, so we want
      to move the mechanism for keeping track of the stats of dead children
      from cfq to blkcg core.  This patch adds blkg_[rw]stat->aux_cnt which
      are atomic64_t's keeping track of auxiliary counts which are excluded
      when reading local counts but included for recursive.

      blkg_[rw]stat_merge() which were used by cfq to implement dead_stats
      are replaced by blkg_[rw]stat_add_aux(), and cfq now forwards stats of
      a dead cgroup to the aux counts of parent->stats instead of separate
      ->dead_stats.

      This will also help making blkg_[rw]stats per-cpu.

      blkcg: consolidate blkg creation in blkcg_bio_issue_check()

      blkg (blkcg_gq) currently is created by blkcg policies invoking
      blkg_lookup_create() which ends up repeating about the same code in
      different policies.  Theoretically, this can avoid the overhead of
      looking and/or creating blkg's if blkcg is enabled but no policy is in
      use; however, the cost of blkg lookup / creation is very low
      especially if only the root blkcg is in use which is highly likely if
      no blkcg policy is in active use - it boils down to a single very
      predictable conditional and surrounding RCU protection.

      This patch consolidates blkg creation to a new function
      blkcg_bio_issue_check() which is called during bio issue from
      generic_make_request_checks().  blkcg_bio_issue_check() is now the
      only function which tries to create missing blkg's.  The subsequent
      policy and request_list operations just perform blkg_lookup() and if
      missing falls back to the root.

      * blk_get_rl() no longer tries to create blkg.  It uses blkg_lookup()
        instead of blkg_lookup_create().

      * blk_throtl_bio() is now called from blkcg_bio_issue_check() with rcu
        read locked and blkg already looked up.  Both throtl_lookup_tg() and
        throtl_lookup_create_tg() are dropped.

      * cfq is similarly updated.  cfq_lookup_create_cfqg() is replaced with
        cfq_lookup_cfqg()which uses blkg_lookup().

      This consolidates blkg handling and avoids unnecessary blkg creation
      retries under memory pressure.  In addition, this provides a common
      bio entry point into blkcg where things like common accounting can be
      performed.

      v2: Build fixes for !CONFIG_CFQ_GROUP_IOSCHED and
          !CONFIG_BLK_DEV_THROTTLING.

      blk-throttle: improve queue bypass handling

      If a queue is bypassing, all blkcg policies should become noops but
      blk-throttle wasn't.  It only became noop if the queue was dying.
      While this wouldn't lead to an oops as falling back to the root blkg
      is safe in this case, this can be a bit surprising - a bypassing queue
      could still be applying throttle limits.

      Fix it by removing blk_queue_dying() test in throtl_lookup_create_tg()
      and testing blk_queue_bypass() in blk_throtl_bio() and bypassing
      before doing anything else.

      blkg_lookup() checks whether the target queue is bypassing and, if

      blkg_lookup() and the fast path part of __blkg_lookup().  The radix
      tree lookup and hint update are now in blkg_lookup_slowpath().

      This will help consolidating blkg handling by easing moving root blkcg

      blkcg: replace blkcg_policy->cpd_size with ->cpd_alloc/free_fn() methods

      Each active policy has a cpd (blkcg_policy_data) on each blkcg.  The
      cpd's were allocated by blkcg core and each policy could request to
      allocate extra space at the end by setting blkcg_policy->cpd_size
      larger than the size of cpd.

      This is a bit unusual but blkg (blkcg_gq) policy data used to be
      handled this way too so it made sense to be consistent; however, blkg
      policy data switched to alloc/free callbacks.

      This patch makes similar changes to cpd handling.
      blkcg_policy->cpd_alloc/free_fn() are added to replace ->cpd_size.  As
      cpd allocation is now done from policy side, it can simply allocate a
      larger area which embeds cpd at the beginning.

      As ->cpd_alloc_fn() may be able to perform all necessary
      initializations, this patch makes ->cpd_init_fn() optional.

      The newly added ->pd_alloc_fn() and ->pd_free_fn() deal with pd
      (blkg_policy_data) while the older ones use blkg (blkcg_gq).  As using
      blkg doesn't make sense for ->pd_alloc_fn() and after allocation pd
      can always be mapped to blkg and given that these are policy-specific
      methods, it makes sense to converge on pd.

      This patch makes all methods deal with pd instead of blkg.  Most
      conversions are trivial.  In blk-cgroup.c, a couple method invocation
      sites now test whether pd exists instead of policy state for
      consistency.  This shouldn't cause any behavioral differences.

      * ->pd_free_fn()

      This leaves ->pd_exit_fn() without any users.  Removed.

      has only one user, into its user.

      blk-throttle: remove asynchrnous percpu stats allocation mechanism

      Because percpu allocator couldn't do non-blocking allocations,
      blk-throttle was forced to implement an ad-hoc asynchronous allocation
      mechanism for its percpu stats for cases where blkg's (blkcg_gq's) are
      allocated from an IO path without sleepable context.

      Now that percpu allocator can handle gfp_mask and blkg_policy_data
      alloc / free are handled by policy methods, the ad-hoc asynchronous
      allocation mechanism can be replaced with direct allocation from
      tg_stats_alloc_fn().  Rit it out.

      This ensures that an active throtl_grp always has valid non-NULL
      ->stats_cpu.  Remove checks on it.

      blkcg: replace blkcg_policy->pd_size with ->pd_alloc/free_fn() methods

      A blkg (blkcg_gq) represents the relationship between a cgroup and
      request_queue.  Each active policy has a pd (blkg_policy_data) on each
      blkg.  The pd's were allocated by blkcg core and each policy could
      request to allocate extra space at the end by setting
      blkcg_policy->pd_size larger than the size of pd.

      This is a bit unusual but was done this way mostly to simplify error
      handling and all the existing use cases could be handled this way;
      however, this is becoming too restrictive now that percpu memory can
      be allocated without blocking.

      This introduces two new mandatory blkcg_policy methods - pd_alloc_fn()
      and pd_free_fn() - which are used to allocate and release pd for a
      given policy.  As pd allocation is now done from policy side, it can
      simply allocate a larger area which embeds pd at the beginning.  This
      change makes ->pd_size pointless.  Removed.

      blkcg: restructure blkg_policy_data allocation in blkcg_activate_policy()

      When a policy gets activated, it needs to allocate and install its
      policy data on all existing blkg's (blkcg_gq's).  Because blkg
      iteration is protected by a spinlock, it currently counts the total
      number of blkg's in the system, allocates the matching number of
      policy data on a list and installs them during a single iteration.

      This can be simplified by using speculative GFP_NOWAIT allocations
      while iterating and falling back to a preallocated policy data on
      failure.  If the preallocated one has already been consumed, it
      releases the lock, preallocate with GFP_KERNEL and then restarts the
      iteration.  This can be a bit more expensive than before but policy

      blkcg: remove unnecessary blkcg_root handling from css_alloc/free paths

      blkcg_css_alloc() bypasses policy data allocation and blkcg_css_free()
      bypasses policy data and blkcg freeing for blkcg_root.  There's no
      reason to to treat policy data any differently for blkcg_root.  If the
      root css gets allocated after policies are registered, policy
      registration path will add policy data; otherwise, the alloc path
      will.  The free path isn't never invoked for root csses.

      This patch removes the unnecessary special handling of blkcg_root from
      css_alloc/free paths.

      blkcg: use blkg_free() in blkcg_init_queue() failure path

      When blkcg_init_queue() fails midway after creating a new blkg, it
      performs kfree() directly; however, this doesn't free the policy data
      areas.  Make it use blkg_free() instead.  In turn, blkg_free() is
      updated to handle root request_list special case.

      While this fixes a possible memory leak, it's on an unlikely failure
      path of an already cold path and the size leaked per occurrence is
      miniscule too.  I don't think it needs to be tagged for -stable.

      cfq-iosched: charge async IOs to the appropriate blkcg's instead of the 
root

      Up until now, all async IOs were queued to async queues which are
      shared across the whole request_queue, which means that blkcg resource
      control is completely void on async IOs including all writeback IOs.
      It was done this way because writeback didn't support writeback and
      there was no way of telling which writeback IO belonged to which
      cgroup; however, writeback recently became cgroup aware and writeback
      bio's are sent down properly tagged with the blkcg's to charge them
      against.

      This patch makes async cfq_queues per-cfq_cgroup instead of
      per-cfq_data so that each async IO is charged to the blkcg that it was
      tagged for instead of unconditionally attributing it to root.

      * cfq_data->async_cfqq and ->async_idle_cfqq are moved to cfq_group
        and alloc / destroy paths are updated accordingly.

      * cfq_link_cfqq_cfqg() no longer overrides @cfqg to root for async
        queues.

      * check_blkcg_changed() now also invalidates async queues as they no
        longer stay the same across cgroups.

      After this patch, cfq's proportional IO control through blkio.weight
      works correctly when cgroup writeback is in use.

      cfq-iosched: fold cfq_find_alloc_queue() into cfq_get_queue()

      cfq_find_alloc_queue() checks whether a queue actually needs to be
      allocated, which is unnecessary as its sole caller, cfq_get_queue(),
      only calls it if so.  Also, the oom queue fallback logic is scattered
      between cfq_get_queue() and cfq_find_alloc_queue().  There really
      isn't much going on in the latter and things can be made simpler by
      folding it into cfq_get_queue().

      This patch collapses cfq_find_alloc_queue() into cfq_get_queue().  The
      change is fairly straight-forward with one exception - async_cfqq is
      now initialized to NULL and the "!is_sync" test in the last if
      conditional is replaced with "async_cfqq" test.  This is because gcc
      (5.1.1) gets confused for some reason and warns that async_cfqq may be
      used uninitialized otherwise.  Oh well, the code isn't necessarily
      worse this way.

      This patch doesn't cause any functional difference.

      cfq-iosched: remove @gfp_mask from cfq_find_alloc_queue()

      Even when allocations fail, cfq_find_alloc_queue() always returns a
      valid cfq_queue by falling back to the oom cfq_queue.  As such, there
      isn't much point in taking @gfp_mask and trying "harder" if __GFP_WAIT
      is set.  GFP_NOWAIT allocations don't fail often and even when they do
      the degraded behavior is acceptable and temporary.

      After all, the only reason get_request(), which ultimately determines
      the gfp_mask, cares about __GFP_WAIT is to guarantee request
      allocation, assuming IO forward progress, for callers which are
      willing to wait.  There's no reason for cfq_find_alloc_queue() to
      behave differently on __GFP_WAIT when it already has a fallback
      mechanism.

      Remove @gfp_mask from cfq_find_alloc_queue() and propagate the changes
      to its callers.  This simplifies the function quite a bit and will
      help making async queues per-cfq_group.

      blkcg, cfq-iosched: use GFP_NOWAIT instead of GFP_ATOMIC for non-critical 
allocations

      blkcg performs several allocations to track IOs per cgroup and enforce
      resource control.  Most of these allocations are performed lazily on
      demand in the IO path and thus can't involve reclaim path.  Currently,
      these allocations use GFP_ATOMIC; however, blkcg can gracefully deal
      with occassional failures of these allocations by punting IOs to the
      root cgroup and there's no reason to reach into the emergency reserve.

      This patch replaces GFP_ATOMIC with GFP_NOWAIT for the following
      allocations.

      * bdi_writeback_congested and blkcg_gq allocations in blkg_create().

      * radix tree node allocations for blkcg->blkg_tree.

      * cfq_queue allocation on ioprio changes.

      cfq-iosched: fix oom cfq_queue ref leak in cfq_set_request()

      If the cfq_queue cached in cfq_io_cq is the oom one, cfq_set_request()
      replaces it by invoking cfq_get_queue() again without putting the oom
      queue leaking the reference it was holding.  While oom queues are not
      released through reference counting, they're still reference counted
      and this can theoretically lead to the reference count overflowing and
      incorrectly invoke the usual release path on it.

      cfq-iosched: fix async oom queue handling

      Async cfqq's (cfq_queue's) are shared across cfq_data.  When
      cfq_get_queue() obtains a new queue from cfq_find_alloc_queue(), it
      stashes the pointer in cfq_data and reuses it from then on; however,
      the function doesn't consider that cfq_find_alloc_queue() may return
      the oom_cfqq under memory pressure and installs the returned queue
      unconditionally.

      If the oom_cfqq is installed as an async cfqq, cfq_set_request() will
      continue calling cfq_get_queue() hoping to replace it with a proper
      queue; however, cfq_get_queue() will keep returning the cached queue
      for the slot - the oom_cfqq.

      Fix it by skipping caching if the queue is the oom one.

      cfq-iosched: simplify control flow in cfq_get_queue()

      cfq_get_queue()'s control flow looks like the following.

        async_cfqq = NULL;
        cfqq = NULL;

        if (!is_sync) {

        if (!is_sync && !(*async_cfqq))
                ...;

      The only thing the local variable init, the second if, and the

      writeback: bdi_for_each_wb() iteration is memcg ID based not blkcg

      wb's (bdi_writeback's) are currently keyed by memcg ID; however, in an
      earlier implementation, wb's were keyed by blkcg ID.
      bdi_for_each_wb() walks bdi->cgwb_tree in the ascending ID order and
      allows iterations to start from an arbitrary ID which is used to
      interrupt and resume iterations.

      Unfortunately, while changing wb to be keyed by memcg ID instead of
      blkcg, bdi_for_each_wb() was missed and is still assuming that wb's
      are keyed by blkcg ID.  This doesn't affect iterations which don't get
      interrupted but bdi_split_work_to_wbs() makes use of iteration
      resuming on allocation failures and thus may incorrectly skip or
      repeat wb's.

      Fix it by changing bdi_for_each_wb() to take memcg IDs instead of
      blkcg IDs and updating bdi_split_work_to_wbs() accordingly.

      HID: usbhid: Fix the check for HID_RESET_PENDING in hid_io_error

      It was reported that after 10-20 reboots, a usb keyboard plugged
      into a docking station would not work unless it was replugged in.

      Using usbmon, it turns out the interrupt URBs were streaming with
      callback errors of -71 for some reason.  The hid-core.c::hid_io_error was
      supposed to retry and then reset, but the reset wasn't really happening.

      The check for HID_NO_BANDWIDTH was inverted.  Fix was simple.

      Tested by reporter and locally by me by unplugging a keyboard halfway 
until I
      could recreate a stream of errors but no disconnect.

      D in DSA patches

      The D in DSA is distributed, meaning multiple switches can be
      connected together. Currently no mainline system does this, and so the
      code is broken. This patchset contains two fixes, and a small helper.

      With three of more switches, the current device tree binding is not
      sufficient to express the routing between the switches. The first
      patch extends the binding, in a backwards compatible way, to allow a
      link between a switch to describe all the switches accessible over the
      link, not just the direct neighbor.

      The third patch fixes the port configuration on newer devices for
      links connecting switches.

      The port needs to be in plain old DSA mode, since this is a DSA link,

      net: dsa: Allow multi hop routes to be expressed

      With more than two switches in a hierarchy, it becomes necessary to
      describe multi-hop routes between switches. The current binding does
      not allow this, although the older platform_data did. Extend the link
      property to be a list rather than a single phandle to a remote switch.
      It is then possible to express that a port should be used to reach
      more than one switch and the switch maybe more than one hop away.

      e1000e: Modify Tx/Rx configurations to avoid null pointer dereferences in

      When e1000e_setup_rx_resources is failed in e1000_open,
      e1000e_free_tx_resources in "err_setup_rx" segment is executed.
      "writel(0, tx_ring->head)" statement in e1000_clean_tx_ring
      in e1000e_free_tx_resources will cause a null poonter dereference(crash),
      because "tx_ring->head" is only assigned in e1000_configure_tx
      in e1000_configure, but it is after e1000e_setup_rx_resources.

      This patch moves head/tail register writing to e1000_configure_tx/rx,
      which can fix this problem. It is inspired by igb_configure_tx_ring
      in the igb driver.

      igb: Teardown SR-IOV before unregister_netdev()

      When the .remove() callback for a PF is called, SR-IOV support for the
      device is disabled, which requires unbinding and removing the VFs.
      The VFs may be in-use either by the host kernel or userspace, such as
      assigned to a VM through vfio-pci.  In this latter case, the VFs may
      be removed either by shutting down the VM or hot-unplugging the
      devices from the VM.  Unfortunately in the case of a Windows 2012 R2
      guest, hot-unplug is broken due to the ordering of the PF driver
      teardown.  Disabling SR-IOV prior to unregister_netdev() avoids this
      issue.

      igb: do not re-init SR-IOV during probe

      During driver probing the following code path is triggered.
      igb_probe

        ->igb_probe_vfs
          ->igb_pci_enable_sriov
            ->igb_sriov_reinit

      Doing the SR-IOV re-init is not necessary during probing since we're
      starting from scratch. Here we can call igb_enable_sriov() right away.

      Running igb_sriov_reinit() during igb_probe() also seems to cause
      occasional packet loss on some onboard 82576 NICs. Reproduced on
      Dell and HP servers with onboard 82576 NICs.

      igb: Fix oops caused by missing queue pairing

      When initializing igb driver (e.g. 82576, I350), IGB_FLAG_QUEUE_PAIRS is
      set if adapter->rss_queues exceeds half of max_rss_queues in
      igb_init_queue_configuration().
      On the other hand, IGB_FLAG_QUEUE_PAIRS is not set even if the number of
      queues exceeds half of max_combined in igb_set_channels() when changing
      the number of queues by "ethtool -L".
      In this case, if numvecs is larger than MAX_MSIX_ENTRIES (10), the size
      of adapter->msix_entries[], an overflow can occur in
      igb_set_interrupt_capability(), which in turn leads to an oops.

      Fix this problem as follows:
       - When changing the number of queues by "ethtool -L", set
         IGB_FLAG_QUEUE_PAIRS in the same way as initializing igb driver.
       - When increasing the size of q_vector, reallocate it appropriately.
         (With IGB_FLAG_QUEUE_PAIRS set, the size of q_vector gets larger.)

      Another possible way to fix this problem is to cap the queues at its
      initial number, which is the number of the initial online cpus. But this
      is not the optimal way because we cannot increase queues when another
      cpu becomes online.

      Note that before commit cd14ef54d25b ("igb: Change to use statically
      allocated array for MSIx entries"), this problem did not cause oops
      but just made the number of queues become 1 because of entering msi_only
      mode in igb_set_interrupt_capability().

channels")

      cgroup: introduce cgroup_subsys->legacy_name

      This allows cgroup subsystems to use a different name on the unified
      hierarchy.  cgroup_subsys->name is used on the unified hierarchy,
      ->legacy_name elsewhere.  If ->legacy_name is not explicitly set, it's
      automatically set to ->name and the userland visible behavior remains
      unchanged.

      v2: Make parse_cgroupfs_options() only consider ->legacy_name as mount
          options are used only on legacy hierarchies.  Suggested by Li
          Zefan.

      cgroup: don't print subsystems for the default hierarchy

      It doesn't make sense to print subsystems on mount option or
      /proc/PID/cgroup for the default hierarchy.

      * cgroup.controllers file at the root of the default hierarchy lists
        the currently attached controllers.

      * The default hierarchy is catch-all for unmounted subsystems.

      * The default hierarchy doesn't accept any mount options.

      Suppress subsystem printing on mount options and /proc/PID/cgroup for
      the default hierarchy.

      block: bump BLK_DEF_MAX_SECTORS to 2560

      A value of 2560 (1280k) will accommodate a 10-data-disk stripe
      write with chunk size 128k.  In the testing I've done using
      iozone, fio, and aio-stress across a number of different storage
      devices, a value of 1280 does not show a big performance
      difference from 512, but will hopefully help software RAID
      setups using SATA disks, as reported by Christoph.

      NOTE: drivers/block/aoe/aoeblk.c sets its own max_hw_sectors_kb to
      BLK_DEF_MAX_SECTORS.  So, this patch essentially changes aeoblk to
      Use a larger maximum sector size, and I did not test this.

      Revert "block: remove artifical max_hw_sectors cap"

      This reverts commit 34b48db66e08ca1c1bc07cf305d672ac940268dc.
      That commit caused performance regressions for streaming I/O
      workloads on a number of different storage devices, from
      SATA disks to external RAID arrays.  It also managed to
      trip up some buggy firmware in at least one drive, causing
      data corruption.

      The next patch will bump the default max_sectors_kb value to
      1280, which will accommodate a 10-data-disk stripe write
      with chunk size 128k.  In the testing I've done using iozone,
      fio, and aio-stress, a value of 1280 does not show a big
      performance difference from 512.  This will hopefully still
      help the software RAID setup that Christoph saw the original
      performance gains with while still not regressing other
      storage configurations.

         and add SNVS power key driver support.
       - Add a second clock for mxc rtc driver, and support device tree probe
         for the driver.

      Those were all workarounds for the formerly double meaning of
      tx_queue_len, which broke scheduling algorithms if untreated.

      Now that all in-tree drivers have been converted away from setting
      tx_queue_len = 0, it should be safe to drop these workarounds for
      categorically broken setups.

      net: warn if drivers set tx_queue_len = 0

      Due to the introduction of IFF_NO_QUEUE, there is a better way for
      drivers to indicate that no qdisc should be attached by default. Though,
      the old convention can't be dropped since ignoring that setting would
      break drivers still using it. Instead, add a warning so out-of-tree
      driver maintainers get a chance to adjust their code before we finally
      get rid of any special handling of tx_queue_len == 0.

      NVMe: Add nvme subsystem reset IOCTL

      Controllers can perform optional subsystem resets as introduced in NVMe
      1.1. This patch adds an IOCTL to trigger the subsystem reset by writing
      "NVMe" to the NSSR register.

      NVMe: Add nvme subsystem reset support

      Controllers part of an NVMe subsystem may be reset by any other controller
      in the subsystem. If the device is capable of subsystem resets, this
      patch adds detection for such events and performs appropriate controller
      initialization upon subsystem reset detection.

      The register bit is a RW1C type, so the driver needs to write a 1 to the
      status bit to clear the subsystem reset occured bit during initialization.

      inode: don't softlockup when evicting inodes

      On a box with a lot of ram (148gb) I can make the box softlockup after 
running
      an fs_mark job that creates hundreds of millions of empty files.  This is
      because we never generate enough memory pressure to keep the number of 
inodes on
      our unused list low, so when we go to unmount we have to evict ~100 
million
      inodes.  This makes one processor a very unhappy person, so add a 
cond_resched()
      in dispose_list() and if we need a resched when processing the s_inodes 
list do
      that and run dispose_list() on what we've currently culled.  Thanks,

      The scanner (here DS3508) always returns 64 bytes per urb buffer. The 
first
      byte indicates the data length used in the current buffer. There even was
      a comment describing this. But the comment also said that we'll send
      everything in the buffer to the tty layer. That means sending the actual
      barcode data and lots of trailing zeroes. This patch lets the driver only

      dmaengine: jz4780: Fall back on smaller transfer sizes where necessary

      For some reason the controller does not support 8 byte transfers (but
      does support all other powers of 2 up to 128). In this case fall back
      to 4 bytes. In addition, fall back to 128 bytes when any larger power
      of 2 would be possible within the alignment constraints, as this is
      the maximum supported.

      It makes no sense to outright reject 8 or >128 bytes just because the
      alignment constraints make those the maximum possible size given the
      parameters for the transaction. For instance, this can result in a DMA
      from/to an 8 byte aligned address failing.

      It is perfectly safe to fall back to smaller transfer sizes, the only
      consequence is reduced transfer efficiency, which is far better than
      not allowing the transfer at all.

      SCSI: Fix NULL pointer dereference in runtime PM

      The routines in scsi_rpm.c assume that if a runtime-PM callback is
      invoked for a SCSI device, it can only mean that the device's driver
      has asked the block layer to handle the runtime power management (by
      calling blk_pm_runtime_init(), which among other things sets q->dev).

      However, this assumption turns out to be wrong for things like the ses
      driver.  Normally ses devices are not allowed to do runtime PM, but
      userspace can override this setting.  If this happens, the kernel gets
      a NULL pointer dereference when blk_post_runtime_resume() tries to use
      the uninitialized q->dev pointer.

      This patch fixes the problem by calling the block layer's runtime-PM
      routines only if the device's driver really does have a runtime-PM
      callback routine.  Since ses doesn't define any such callbacks, the
      crash won't occur.

      This fixes Bugzilla #101371.

      fnic: Use the local variable instead of I/O flag to acquire io_req_lock 
in fnic_queuecommand() to avoid deadloack

      We added changes in fnic driver patch 1.6.0.16 to acquire
      io_req_lock in fnic_queuecommand() before issuing I/O so that io 
completion
      is serialized. But when releasing the lock we check for the I/O flag and
      this could be modified if IO abort occurs before I/O completion. In this 
case
      we wont release the lock and causes deadlock in some scenerios. Using the
      local variable to check the IO lock status will resolve the problem.

      ARM: 8415/1: early fixmap support for earlycon

      Add early fixmap support, initially to support permanent, fixed
      mapping support for early console. A temporary, early pte is
      created which is migrated to a permanent mapping in paging_init.
      This is also needed since the attributes may change as the memory
      types are initialized. The 3MiB range of fixmap spans two pte
      tables, but currently only one pte is created for early fixmap
      support.

      Re-add FIX_KMAP_BEGIN to the index calculation in highmem.c since
      the index for kmap does not start at zero anymore. This reverts
      4221e2e6b316 ("ARM: 8031/1: fixmap: remove FIX_KMAP_BEGIN and
      FIX_KMAP_END") to some extent.

      drm: bridge/dw_hdmi: fix phy enable/disable handling

      The dw_hdmi enable/disable handling is particularly weak in several
      regards:
      * The hotplug interrupt could call hdmi_poweron() or hdmi_poweroff()
        while DRM is setting a mode, which could race with a mode being set.
      * Hotplug will always re-enable the phy whenever it detects an active
        hotplug signal, even if DRM has disabled the output.

      Resolve all of these by introducing a mutex to prevent races, and a
      state-tracking bool so we know whether DRM wishes the output to be
      enabled.  We choose to use our own mutex rather than ->struct_mutex
      so that we can still process interrupts in a timely fashion.

      drm: bridge/dw_hdmi: rename dw_hdmi_phy_enable_power()

      dw_hdmi_phy_enable_power() is not about enabling and disabling power.
      It is about allowing or preventing power-down mode being entered - the
      register is documented as "Power-down enable (active low 0b)."

      This can be seen as the bit has no effect when the HDMI phy is
      operational on iMX6 hardware.

      Rename the function to dw_hdmi_phy_enable_powerdown() to reflect the
      documentation, make it take a bool for the 'enable' argument, and invert
      the value to be written.

      drm: bridge/dw_hdmi: avoid enabling interface in mode_set

      On a mode set, DRM makes the following sequence of calls:
      * for_each_encoder
      *   bridge        mode_fixup
      *   encoder       mode_fixup
      * crtc            mode_fixup
      * for_each_encoder
      *   bridge        disable
      *   encoder       prepare
      *   bridge        post_disable
      * disable unused encoders
      * crtc            prepare
      * crtc            mode_set
      * for_each_encoder
      *   encoder       mode_set
      *   bridge        mode_set
      * crtc            commit

      *   encoder       commit
      *   bridge        enable

      dw_hdmi enables the HDMI output in both the bridge mode_set() and also
      the bridge enable() step.  This is duplicated work - we can avoid the
      setup in mode_set() and just do it in the enable() stage.  This
      simplifies the code a little.

      drm: bridge/dw_hdmi: clean up HDMI vs DVI mode handling

      The FSL kernel detects the HDMI vendor id, and uses this to set
      hdmi->edid_cfg.hdmi_cap, which is then used to set mdvi appropriately,
      rather than detecting whether we are outputting a CEA mode.  Update
      the dw_hdmi code to use this logic, but lets eliminate the mdvi
      variable, prefering the more verbose "hdmi->sink_is_hdmi" instead.

      Use the generic drm_detect_hdmi_monitor() to detect a HDMI sink.

      drm: bridge/dw_hdmi: remove pixel repetition setting for all VICs

      dw_hdmi sets a pixel repetition factor of 1 for VICs 10-15, 25-30 and
      35-38.  However, DRM uses their native resolutions in its timing
      information.  For example, VIC 14 can be 1440x480 with no repetition,
      or 720x480 with one pixel repetition.  As DRM uses 1440 pixels per line
      for this video mode, we need no pixel repetition.

      In any case, pixel repetition appears broken in dw_hdmi.

      drm: bridge/dw_hdmi: introduce interfaces to enable and disable audio

      iMX6 devices suffer from an errata (ERR005174) where the audio FIFO can
      be emptied while it is partially full, resulting in misalignment of the
      audio samples.

      To prevent this, the errata workaround recommends writing N as zero
      until the audio FIFO has been loaded by DMA.  Writing N=0 prevents the
      HDMI bridge from reading from the audio FIFO, effectively disabling
      audio.

      This means we need to provide the audio driver with a pair of functions
      to enable/disable audio.  These are dw_hdmi_audio_enable() and
      dw_hdmi_audio_disable().

      A spinlock is introduced to ensure that setting the CTS/N values can't
      race, ensuring that the audio driver calling the enable/disable
      functions (which are called in an atomic context) can't race with a
      modeset.

      cxl: Add alternate MMIO error handling

      userspace programs using cxl currently have to use two strategies for
      dealing with MMIO errors simultaneously. They have to check every read
      for a return of all Fs in case the adapter has gone away and the kernel
      has not yet noticed, and they have to deal with SIGBUS in case the
      kernel has already noticed, invalidated the mapping and marked the
      context as failed.

      In order to simplify things, this patch adds an alternative approach
      where the kernel will return a page filled with Fs instead of delivering
      a SIGBUS. This allows userspace to only need to deal with one of these
      two error paths, and is intended for use in libraries that use cxl
      transparently and may not be able to safely install a signal handler.

      This approach will only work if certain constraints are met. Namely, if
      the application is both reading and writing to an address in the problem
      state area it cannot assume that a non-FF read is OK, as it may just be
      reading out a value it has previously written. Further - since only one
      page is used per context a write to a given offset would be visible when
      reading the same offset from a different page in the mapping (this only
      applies within a single context, not between contexts).

      An application could deal with this by e.g. making sure it also reads
      from a read-only offset after any reads to a read/write offset.

      Due to these constraints, this functionality must be explicitly
      requested by userspace when starting the context by passing in the
      CXL_START_WORK_ERR_FF flag.

      pcibios_set_pcie_reset_state() could be called to complete
      reset request when passing through PCI device, flag
      EEH_PE_ISOLATED is set before saving the PCI config sapce.
      On some Broadcom adapters, EEH_PE_CFG_BLOCKED is automatically
      set when the flag EEH_PE_ISOLATED is marked. It caused bogus
      data saved from the PCI config space, which will be restored

      doesn't set EEH_PE_CFG_BLOCKED when seeing EEH_PE_ISOLATED on the
      PE, in order to avoid the bogus data saved and restored to the PCI

      powerpc/pseries: enable RTC class support

      A working rtc kernel driver is needed so that hwclock can synchronize
      system clock to rtc during shutdown/boot. We already have a powernv
      platform rtc driver located at drivers/rtc/rtc-opal.c. However it depends
      on CONFIG_RTC_CLASS which is disabled by default. Hence the driver isn't
      enabled and not compiled for the powernv kernel.

      We fix this by enabling rtc class support in pseries defconfig which
      enables this driver and compiles it into the pseries kernel. In case

      powerpc/numa: initialize distance lookup table from drconf path

      In some situations, a NUMA guest that supports
      ibm,dynamic-memory-reconfiguration node will end up having flat NUMA
      distances between nodes. This is because of two problems in the
      current code.

      1) Different representations of associativity lists.

         There is an assumption about the associativity list in
         initialize_distance_lookup_table(). Associativity list has two forms:

         a) [cpu,memory]@x/ibm,associativity has following
            format:
                 <N> <N integers>

         b) ibm,dynamic-reconfiguration-memory/ibm,associativity-lookup-arrays

                 <M> <N> <M associativity lists each having N integers>
                 M = the number of associativity lists
                 N = the number of entries per associativity list

         Fix initialize_distance_lookup_table() so that it does not assume
         "case a". And update the caller to skip the length field before
         sending the associativity list.

      2) Distance table not getting updated from drconf path.

         Node distance table will not get initialized in certain cases as
         ibm,dynamic-reconfiguration-memory path does not initialize the
         lookup table.

         Call initialize_distance_lookup_table() from drconf path with
         appropriate associativity list.

      powerpc/powernv: move dma_get_required_mask from pnv_phb to 
pci_controller_ops

      Simplify the dma_get_required_mask call chain by moving it from pnv_phb to
      pci_controller_ops, similar to commit 763d2d8df1ee ("powerpc/powernv:
      Move dma_set_mask from pnv_phb to pci_controller_ops").

      Previous call chain:

        0) call dma_get_required_mask() (kernel/dma.c)
        1) call ppc_md.dma_get_required_mask, if it exists. On powernv, that
           points to pnv_dma_get_required_mask() (platforms/powernv/setup.c)
        2) device is PCI, therefore call pnv_pci_dma_get_required_mask()
           (platforms/powernv/pci.c)
        3) call phb->dma_get_required_mask if it exists
        4) it only exists in the ioda case, where it points to
             pnv_pci_ioda_dma_get_required_mask() (platforms/powernv/pci-ioda.c)

      New call chain:

        0) call dma_get_required_mask() (kernel/dma.c)
        1) device is PCI, therefore call 
pci_controller_ops.dma_get_required_mask
           if it exists
        2) in the ioda case, that points to pnv_pci_ioda_dma_get_required_mask()
           (platforms/powernv/pci-ioda.c)

      In the p5ioc2 case, the call chain remains the same -
      dma_get_required_mask() does not find either a ppc_md call or
      pci_controller_ops call, so it calls __dma_get_required_mask().

      powerpc/mm: Drop CONFIG_PPC_HAS_HASH_64K

      The relation between CONFIG_PPC_HAS_HASH_64K and CONFIG_PPC_64K_PAGES is
      painfully complicated.

      But if we rearrange it enough we can see that PPC_HAS_HASH_64K
      essentially depends on PPC_STD_MMU_64 && PPC_64K_PAGES.

      We can then notice that PPC_HAS_HASH_64K is used in files that are only
      built for PPC_STD_MMU_64, meaning it's equivalent to PPC_64K_PAGES.

      So replace all uses and drop it.

      For config options with only a single value, guarding the single value

      powerpc/cell: Drop support for 64K local store on 4K kernels

      Back in the olden days we added support for using 64K pages to map the
      SPU (Synergistic Processing Unit) local store on Cell, when the main
      kernel was using 4K pages.

      This was useful at the time because distros were using 4K pages, but
      using 64K pages on the SPUs could reduce TLB pressure there.

      However these days the number of Cell users is approaching zero, and
      supporting this option adds unpleasant complexity to the memory
      management code.

      So drop the option, CONFIG_SPU_FS_64K_LS, and all related code.

      powerpc/mm: Fix pte_pagesize_index() crash on 4K w/64K hash

      The powerpc kernel can be built to have either a 4K PAGE_SIZE or a 64K
      PAGE_SIZE.

      However when built with a 4K PAGE_SIZE there is an additional config
      option which can be enabled, PPC_HAS_HASH_64K, which means the kernel
      also knows how to hash a 64K page even though the base PAGE_SIZE is 4K.

      This is used in one obscure configuration, to support 64K pages for SPU
      local store on the Cell processor when the rest of the kernel is using
      4K pages.

      In this configuration, pte_pagesize_index() is defined to just pass
      through its arguments to get_slice_psize(). However pte_pagesize_index()
      is called for both user and kernel addresses, whereas get_slice_psize()
      only knows how to handle user addresses.

      This has been broken forever, however until recently it happened to
      work. That was because in get_slice_psize() the large kernel address
      would cause the right shift of the slice mask to return zero.

      However in commit 7aa0727f3302 ("powerpc/mm: Increase the slice range to
      64TB"), the get_slice_psize() code was changed so that instead of a
      right shift we do an array lookup based on the address. When passed a
      kernel address this means we index way off the end of the slice array
      and return random junk.

      That is only fatal if we happen to hit something non-zero, but when we
      do return a non-zero value we confuse the MMU code and eventually cause
      a check stop.

      This fix is ugly, but simple. When we're called for a kernel address we
      return 4K, which is always correct in this configuration, otherwise we
      use the slice mask.

      iommu/io-pgtable-arm: Unmap and free table when overwriting with block

      When installing a block mapping, we unconditionally overwrite a non-leaf
      PTE if we find one. However, this can cause a problem if the following
      sequence of events occur:

        (1) iommu_map called for a 4k (i.e. PAGE_SIZE) mapping at some address
            - We initialise the page table all the way down to a leaf entry
            - No TLB maintenance is required, because we're going from invalid
              to valid.

        (2) iommu_unmap is called on the mapping installed in (1)
            - We walk the page table to the final (leaf) entry and zero it
            - We only changed a valid leaf entry, so we invalidate leaf-only

        (3) iommu_map is called on the same address as (1), but this time for
            a 2MB (i.e. BLOCK_SIZE) mapping)
            - We walk the page table down to the penultimate level, where we
              find a table entry
            - We overwrite the table entry with a block mapping and return
              without any TLB maintenance and without freeing the memory used
              by the now-orphaned table.

      This last step can lead to a walk-cache caching the overwritten table
      entry, causing unexpected faults when the new mapping is accessed by a
      device. One way to fix this would be to collapse the page table when
      freeing the last page at a given level, but this would require expensive
      iteration on every map call. Instead, this patch detects the case when
      we are overwriting a table entry and explicitly unmaps the table first,
      which takes care of both freeing and TLB invalidation.

      iwlwifi: mvm: fix a race in D0i3 vs. Tx path

      When we enter D0i3, we must stop TXing otherwise the
      sequence number we use might conflict with the firmware's
      internal TX. In order to do so, we have
      IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
      enter D0i3. There is a bug in this code since we may Tx even
      if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
      mvm->d0i3_ap_sta_id is not set.

      To make sure that we don't have any packet in the Tx path
      while we set mvm->d0i3_ap_sta_id, call synchronize_net only
      after we already set mvm->d0i3_ap_sta_id.

      rtlwifi: rtl8192cu: Remove and replace routine in hw.c and mac.c

      I remove duplicated routines which related rtl92cu_set_hw_reg().

      1. rtl92c_set_qos() and HW_VAR_AC_PARAM routine are similar code.
      so i replace code with rtlpriv->cfg->ops->set_hw_reg().

      2. rtl92c_set_mac_addr() and 'HW_VAR_ETHER_ADDR' case at
      rtl92cu_set_hw_reg() routine are similar code.
      so i removed rtl92c_set_mac_addr() function.
      also it was not used anywhere.

      3. remove HW_VAR_ACM_CTRL routine in rtl92cu_set_hw_reg().
      if rtl_usb->acm_method is not EACMWAY2_SW, HW_VAR_ACM_CTRL is called
      from HW_VAR_AC_PARAM. but it never called. because acm_method is always
      EACMWAY2_SW. so i remove acm_method check routine
      and HW_VAR_ACM_CTRL routine.

      both usb and pci interface is not used HW_VAR_ACM_CTRL.
      but i can't test pci interface module, so i didn't modify pci code.

      Merge branch 'Identifier-Locator-Addressing'

      Tom Herbert says:

      ====================
      net: Identifier Locator Addressing - Part I

      This patch set provides rudimentary support for Identifier Locator
      Addressing or ILA. The basic concept of ILA is that we split an IPv6
      address into a 64 bit locator and 64 bit identifier. The identifier is
      the identity of an entity in communication ("who"), and the locator
      expresses the location of the entity ("where"). Applications
      use externally visible address that contains the identifier.
      When a packet is actually sent, a translation is done that
      overwrites the first 64 bits of the address with a locator.
      The packet can then be forwarded over the network to the host where
      the addressed entity is located. At the receiver, the reverse
      translation is done so the that the application sees the original,
      untranslated address. Presumably an external control plane will
      provide identifier->locator mappings.

      v2:
        - Fix compilation erros when LWT not configured
        - Consolidate ILA into a single ila.c

      v3:
        - Change pseudohdr argument od inet_proto_csum_replace functions to
          be a bool

      v4:
        - In ila_build_state check locator being in netlink params before
          allocating tunnel state

      The data path for ILA is a simple NAT translation that only operates
      on the upper 64 bits of a destination address in IPv6 packets. The
      basic process is:

         1) Lookup 64 bit identifier (lower 64 bits of destination)
         2) If a match is found
            a) Overwrite locator (upper 64 bits of destination) with
               the new locator
            b) Adjust any checksum that has destination address included in
               pseudo header
         3) Send or receive packet

      ILA is a means to implement tunnels or network virtualization without
      encapsulation. Since there is no encapsulation involved, we assume that
      stateless support in the network for IPv6 (e.g. RSS, ECMP, TSO, etc.)
      just works. Also, since we're minimally changing the packet many of
      the worries about encapsulation (MTU, checksum, fragmentation) are
      not relevant. The downside is that, ILA is not extensible like other
      encapsulations (GUE for instance) so it might not be appropriate for
      all use cases. Also, this only makes sense to do in IPv6!

      A key aspect of ILA is performance. The intent is that ILA would be
      used in data centers in virtualizing tasks or jobs. In the fullest
      incarnation all intra data center communications might be targeted to
      virtual ILA addresses. This is basically adding a new virtualization
      capability to the existing services in a datacenter, so there is a
      strong expectation is that this does not degrade performance for
      existing applications.

      Performance seems to be dependent on how ILA is hooked into kernel.
      ILA can be implemented under some different models:

        - Mechanically it is a form a stateless DNAT
        - It can be thought of as a type of (source) routing
        - As a functional replacement of encapsulation

      In this patch set we hook into the data path using Light Weight
      Tunnels (LWT) infrastructure. As part of that, we add support in LWT
      to redirect dst input. iproute will be modified to take a new ila encap
      type. ILA can be configured like:

      ip route add 3333:0:0:1:5555:0:2:0/128 \
         encap ila 2001:0:0:2 via 2401:db00:20:911a:face:0:27:0

      ip -6 addr add 3333:0:0:1:5555:0:1:0/128 dev eth0

      ip route add table local local 2001:0:0:1:5555:0:1:0/128
         encap ila 3333:0:0:1 dev lo

      So sending to destination 3333:0:0:1:5555:0:2:0 will have destination
      of 2001:0:0:2:5555:0:2:0 on the wire.

      Performance results are below. With ILA we see about a 10% drop in
      pps compared to non-ILA. Much of this drop can be attributed to the
      loss of early demux on input (translation occurs after it is attempted).
      We will address this in the next patch set. Also, IPvlan input path
      does not work with ILA since the routing is bypassed-- this will
      be addressed in a future patch.

      Performance testing:

      Performing netperf TCP_RR with 200 clients:

      Non-ILA baseline
        84.92% CPU utilization
        1861922.9 tps
        93/163/330 50/90/99% latencies

      ILA single destination
        83.16% CPU utilization
        1679683.4 tps
        105/180/332 50/90/99% latencies

      inode: rename i_wb_list to i_io_list

      There's a small consistency problem between the inode and writeback
      naming. Writeback calls the "for IO" inode queues b_io and
      b_more_io, but the inode calls these the "writeback list" or
      i_wb_list. This makes it hard to an new "under writeback" list to
      the inode, or call it an "under IO" list on the bdi because either
      way we'll have writeback on IO and IO on writeback and it'll just be
      confusing. I'm getting confused just writing this!

      So, rename the inode "for IO" list variable to i_io_list so we can
      add a new "writeback list" in a subsequent patch.

      crypto: caam - add support for LS1021A

      LS1021A is a QorIQ SoC having little endian CAAM.

      There are a few differences b/w QorIQ and i.MX from CAAM perspective:

      1. i.MX platforms are somewhat special wrt. 64-bit registers:
      -big endian format at 64-bit level: MSW at address+0 and LSW at address+4
      -little endian format at 32-bit level (within MSW and LSW)
      and thus need special handling.

      2. No CCM (clock controller module) for QorIQ.
      No CAAM clocks to enable / disable.

      A new Kconfig option - CRYPTO_DEV_FSL_CAAM_LE - is added to indicate
      CAAM is little endian (*). It is hidden from the user (to avoid
      misconfiguration); when adding support for a new platform with LE CAAM,
      either the Kconfig needs to be updated or the corresponding defconfig
      needs to indicate that CAAM is LE.
      (*) Using a DT property to provide CAAM endianness would not allow
      for the ifdeffery.

      In order to keep changes to a minimum, the following changes
      are postponed:
      -endianness fix of the last word in the S/G (rsvd2, bpid, offset),
      fields are always 0 anyway;
      -S/G format fix for i.MX7 (yes, i.MX7 support was not added yet,
      but still...)

      LE/BE order, in first case it'll generate a wrong
      table resulting in wrong hashes from the algorithm.

      Bug affects only LE machines.
      In order to fix it we do a swap for loaded key.

      netfilter: nf_conntrack: add efficient mark to zone mapping

      This work adds the possibility of deriving the zone id from the skb->mark
      field in a scalable manner. This allows for having only a single template
      serving hundreds/thousands of different zones, for example, instead of the
      need to have one match for each zone as an extra CT jump target.

      Note that we'd need to have this information attached to the template as 
at
      the time when we're trying to lookup a possible ct object, we already need
      to know zone information for a possible match when going into
      __nf_conntrack_find_get(). This work provides a minimal implementation for
      a possible mapping.

      In order to not add/expose an extra ct->status bit, the zone structure has
      been extended to carry a flag for deriving the mark.

      netfilter: nf_conntrack: add direction support for zones

      This work adds a direction parameter to netfilter zones, so identity
      separation can be performed only in original/reply or both directions
      (default). This basically opens up the possibility of doing NAT with
      conflicting IP address/port tuples from multiple, isolated tenants
      on a host (e.g. from a netns) without requiring each tenant to NAT
      twice resp. to use its own dedicated IP address to SNAT to, meaning
      overlapping tuples can be made unique with the zone identifier in
      original direction, where the NAT engine will then allocate a unique
      tuple in the commonly shared default zone for the reply direction.
      In some restricted, local DNAT cases, also port redirection could be
      used for making the reply traffic unique w/o requiring SNAT.

      The consensus we've reached and discussed at NFWS and since the initial
      implementation [1] was to directly integrate the direction meta data
      into the existing zones infrastructure, as opposed to the ct->mark
      approach we proposed initially.

      As we pass the nf_conntrack_zone object directly around, we don't have
      to touch all call-sites, but only those, that contain equality checks
      of zones. Thus, based on the current direction (original or reply),
      we either return the actual id, or the default NF_CT_DEFAULT_ZONE_ID.
      CT expectations are direction-agnostic entities when expectations are
      being compared among themselves, so we can only use the identifier
      in this case.

      Note that zone identifiers can not be included into the hash mix
      anymore as they don't contain a "stable" value that would be equal
      for both directions at all times, f.e. if only zone->id would
      unconditionally be xor'ed into the table slot hash, then replies won't
      find the corresponding conntracking entry anymore.

      If no particular direction is specified when configuring zones, the
      behaviour is exactly as we expect currently (both directions).

      Support has been added for the CT netlink interface as well as the
      x_tables raw CT target, which both already offer existing interfaces
      to user space for the configuration of zones.

      Below a minimal, simplified collision example (script in [2]) with
      netperf sessions:

        +--- tenant-1 ---+   mark := 1
        |    netperf     |--+
        +----------------+  |                CT zone := mark [ORIGINAL]
         [ip,sport] := X   +--------------+  +--- gateway ---+
                           | mark routing |--|     SNAT      |-- ... +
                           +--------------+  +---------------+       |
        +--- tenant-2 ---+  |                                     ~~~|~~~
        |    netperf     |--+                +-----------+           |
        +----------------+   mark := 2       | netserver |------ ... +
         [ip,sport] := X                     +-----------+
                                              [ip,port] := Y
      On the gateway netns, example:

        iptables -t raw -A PREROUTING -j CT --zone mark --zone-dir ORIGINAL
        iptables -t nat -A POSTROUTING -o <dev> -j SNAT --to-source <ip> 
--random-fully

        iptables -t mangle -A PREROUTING -m conntrack --ctdir ORIGINAL -j 
CONNMARK --save-mark
        iptables -t mangle -A POSTROUTING -m conntrack --ctdir REPLY -j

      Taking this further, test script in [2] creates 200 tenants and runs
      original-tuple colliding netperf sessions each. A conntrack -L dump in
      the gateway netns also confirms 200 overlapping entries, all in 
ESTABLISHED
      state as expected.

      I also did run various other tests with some permutations of the script,
      to mention some: SNAT in random/random-fully/persistent mode, no zones (no
      overlaps), static zones (original, reply, both directions), etc.

      net/mlx5e: Ethtool link speed setting fixes

      - Port speed settings are applied by the device only upon
        port admin status transition from DOWN to UP.
        So we enforce this transition regardless of the port's
        current operation state (which may be occasionally DOWN if
        for example the network cable is disconnected).
      - Fix the PORT_UP/DOWN device interface enum
      - Set the local_port bit in the device PAOS register
      - EXPORT the PAOS (Port Administrative and Operational Status)
        register set/query access functions.

      sync: serialise per-superblock sync operations

      When competing sync(2) calls walk the same filesystem, they need to
      walk the list of inodes on the superblock to find all the inodes
      that we need to wait for IO completion on. However, when multiple
      wait_sb_inodes() calls do this at the same time, they contend on the
      the inode_sb_list_lock and the contention causes system wide
      slowdowns. In effect, concurrent sync(2) calls can take longer and
      burn more CPU than if they were serialised.

      Stop the worst of the contention by adding a per-sb mutex to wrap
      around wait_sb_inodes() so that we only execute one sync(2) IO
      completion walk per superblock superblock at a time and hence avoid
      contention being triggered by concurrent sync(2) calls.

      inode: convert inode_sb_list_lock to per-sb

      The process of reducing contention on per-superblock inode lists
      starts with moving the locking to match the per-superblock inode
      list. This takes the global lock out of the picture and reduces the
      contention problems to within a single filesystem. This doesn't get
      rid of contention as the locks still have global CPU scope, but it
      does isolate operations on different superblocks form each other.

      inode: add hlist_fake to avoid the inode hash lock in evict

      Some filesystems don't use the VFS inode hash and fake the fact they
      are hashed so that all the writeback code works correctly. However,
      this means the evict() path still tries to remove the inode from the
      hash, meaning that the inode_hash_lock() needs to be taken
      unnecessarily. Hence under certain workloads the inode_hash_lock can
      be contended even if the inode is never actually hashed.

      To avoid this add hlist_fake to test if the inode isn't actually
      hashed to avoid taking the hash lock on inodes that have never been
      hashed.  Based on Dave Chinner's

      inode: add IOP_NOTHASHED to avoid inode hash lock in evict

      basd on Al's suggestions.  Thanks,

      writeback: plug writeback at a high level

      Doing writeback on lots of little files causes terrible IOPS storms
      because of the per-mapping writeback plugging we do. This
      essentially causes imeediate dispatch of IO for each mapping,
      regardless of the context in which writeback is occurring.

      IOWs, running a concurrent write-lots-of-small 4k files using fsmark
      on XFS results in a huge number of IOPS being issued for data
      writes.  Metadata writes are sorted and plugged at a high level by
      XFS, so aggregate nicely into large IOs. However, data writeback IOs
      are dispatched in individual 4k IOs, even when the blocks of two
      consecutively written files are adjacent.

      Test VM: 8p, 8GB RAM, 4xSSD in RAID0, 100TB sparse XFS filesystem,
      metadata CRCs enabled.

      Kernel: 3.10-rc5 + xfsdev + my 3.11 xfs queue (~70 patches)

      Test:

      $ ./fs_mark  -D  10000  -S0  -n  10000  -s  4096  -L  120  -d
      /mnt/scratch/0  -d  /mnt/scratch/1  -d  /mnt/scratch/2  -d
      /mnt/scratch/3  -d  /mnt/scratch/4  -d  /mnt/scratch/5  -d
      /mnt/scratch/6  -d  /mnt/scratch/7

      Result:

                wall    sys     create rate     Physical write IO
                time    CPU     (avg files/s)    IOPS   Bandwidth

      If I use zero length files, this workload at about 500 IOPS, so
      plugging drops the data IOs from roughly 25,500/s to 1000/s.
      3 lines of code, 35% better throughput for 15% less CPU.

      The benefits of plugging at this layer are likely to be higher for
      spinning media as the IO patterns for this workload are going make a
      much bigger difference on high IO latency devices.....

      This series adds new devcmd2 support. The first two patches are code
      refactoring.

      devcmd is an interface for driver to communicate with fw/adaptor. It
      involves writing data to hardware registers and waiting for the result.
      This mechanism does not scale well. The queuing of "no wait" devcmds is
      done in firmware memory rather than on the host. Firmware memory is a
      rather more scarce and valuable resource than host memory. A devcmd storm
      from one vf can disrupt the service on other pf/vf. The lack of flow
      control allows for possible denial of server from one VM to another.
      Devcmd2 uses work queue to post the devcmds, just like tx work queue. This
      allows better flow control.

      NVMe: Set queue max segments

      This sets the queue's max segment size to match the device's
      capabilities. The default of 128 is usable until a device's transfer
      capability exceeds 512k, assuming a device page size of 4k. Many nvme
      devices exceed that transfer limit, so this lets the block layer know what
      kind of commands it to allow to form rather than unnecessarily split them.

      One additional segment is added to account for a transfer that may start
      in the middle of a page.

      rhashtable-test: extend to test concurrency

      After having tested insertion, lookup, table walk and removal, spawn a
      number of threads running operations on the same rhashtable. Each of
      them will:

      1) insert it's own set of objects,
      2) lookup every successfully inserted object and finally
      3) remove objects in several rounds until all of them have been removed,
         making sure the remaining ones are still found after each round.

      This should put a good amount of load onto the system and due to
      synchronising thread startup via two semaphores also extensive
      concurrent table access.

      The default number of ten threads returned within half a second on my
      local VM with two cores. Running 200 threads took about four seconds. If
      slow systems suffer too much from this though, the default could be
      lowered or even set to zero so this extended test does not run at all by
      default.

      packet: add cBPF and eBPF fanout modes

      Allow programmable fanout modes. Support both classical BPF programs
      passed directly and extended BPF programs passed by file descriptor.

      One use case is packet steering by deep packet inspection, for
      instance for packet steering by application layer header fields.

      Separate the configuration of the fanout mode and the configuration
      of the program, to allow dynamic updates to the latter at runtime.

      Changes
        v1 -> v2:
          - follow SO_LOCK_FILTER semantics on filter updates
          - only accept eBPF programs of type BPF_PROG_TYPE_SOCKET_FILTER
          - rename PACKET_FANOUT_BPF to PACKET_FANOUT_CBPF to match
            man 2 bpf usage: "classic" vs. "extended" BPF.

      dlm: fix reconnecting but not sending data

      There are cases on which lowcomms_connect_sock() is called directly,
      which caused the CF_WRITE_PENDING flag to not bet set upon reconnect,
      specially on send_to_sock() error handling. On this last, the flag was
      already cleared and no further attempt on transmitting would be done.

      As dlm tends to connect when it needs to transmit something, it makes
      sense to always mark this flag right after the connect.

      dlm: replace BUG_ON with a less severe handling

      BUG_ON() is a severe action for this case, specially now that DLM with
      SCTP will use 1 socket per association. Instead, we can just close the
      socket on this error condition and return from the function.

      Also move the check to an earlier stage as it won't change and thus we
      can abort as soon as possible.

      Although this issue was reported when still using SCTP with 1-to-many
      API, this cleanup wouldn't be that simple back then because we couldn't
      close the socket and making sure such event would cease would be hard.
      And actually, previous code was closing the association, yet SCTP layer
      is still raising the new data event. Probably a bug to be fixed in SCTP.

      dlm: use sctp 1-to-1 API

      DLM is using 1-to-many API but in a 1-to-1 fashion. That is, it's not
      needed but this causes it to use sctp_do_peeloff() to mimic an
      kernel_accept() and this causes a symbol dependency on sctp module.

      By switching it to 1-to-1 API we can avoid this dependency and also
      reduce quite a lot of SCTP-specific code in lowcomms.c.

      The caveat is that now DLM won't always use the same src port. It will
      choose a random one, just like TCP code. This allows the peers to
      attempt simultaneous connections, which now are handled just like for
      TCP.

      Even more sharing between TCP and SCTP code on DLM is possible, but it
      is intentionally left for a later commit.

      Note that for using nodes with this commit, you have to have at least
      the early fixes on this patchset otherwise it will trigger some issues
      on old nodes.

      When a connection have issues DLM may need to close it.  Therefore we

      Also, if we don't clear CF_CONNECT_PENDING flag, the error handling

      dlm: fix connection stealing if using SCTP

      When using SCTP and accepting a new connection, DLM currently validates
      if the peer trying to connect to it is one of the cluster nodes, but it
      doesn't check if it already has a connection to it or not.

      If it already had a connection, it will be overwritten, and the new one
      will be used for writes, possibly causing the node to leave the cluster
      due to communication breakage.

      Still, one could DoS the node by attempting N connections and keeping
      them open.

      As said, but being explicit, both situations are only triggerable from
      other cluster nodes, but are doable with only user-level perms.

      lwtunnel: rename ip lwtunnel attributes

      We already have IFLA_IPTUN_ netlink attributes. The IP_TUN_ attributes 
look
      very similar, yet they serve very different purpose. This is confusing for
      anyone trying to implement a user space tool supporting lwt.

      As the IP_TUN_ attributes are used only for the lightweight tunnels, 
prefix
      them with LWTUNNEL_IP_ instead to make their purpose clear. Also, it's 
more
      logical to have them in lwtunnel.h together with the encap enum.

      Commit 0b50dc4fc971 ("Convert smsc911x to use ACPI as well as DT") makes
      the call to smsc911x_probe_config() unconditional, and no longer fails if
      there is no device node. device_get_phy_mode() is called unconditionally,
      and if there is no phy node configured returns an error code. This error
      code is assigned to phy_interface, and interpreted elsewhere in the code
      as valid phy mode. This in turn causes qemu to crash when running a
      variant of realview_pb_defconfig.

      drm/amdgpu: don't grab dev->struct_mutex in pm functions

      Similar to radeon, except that amdgpu doesn't even use struct_mutex to
      protect anything like the shared z buffer (sane gpu architecture,
      yay!). And the code already grabs the globa adev->ring_lock, so this
      code can't race with itself. Which makes struct_mutex completely
      redundnant. Remove it.

      It really doesn't protect anything which doesn't have other locks
      already. Also this is run from driver unload code so not much need for
      locks anyway.

      Same changes as for radeon really.

      drm/radeon: Don't take dev->struct_mutex in pm functions

      We already grab 2 device-global locks (write-sema rdev->pm.mclk_lock
      and rdev->ring_lock), adding another global mutex won't serialize this
      code more. And since there's really nothing interesting that gets
      protected in radeon by dev->struct mutex (we only have the global z
      buffer owners and it's still serializing gem bo destruction in the drm
      core - which is irrelevant since radeon uses ttm anyway internally)
      this doesn't add protection. Remove it.

      drm/amdgpu: remove VI hw bug workaround v3

      The workaround simply doesn't work because VM mappings
      are controlled by userspace not the kernel.

      Additional to that this is just a performance problem
      which happens if you have holes in your VM mapping.

      v2: adjust virtual addr alignment as well.

      It is theoretically possible that a swapped out BO gets the

      Instead just use another VA state to note updated areas.

      run queue:
      A set of entities scheduling commands for the same ring. It
      implements the scheduling policy that selects the next entity to
      emit commands from.

      entity:
      A scheduler entity is a wrapper around a job queue or a group of
      other entities. This can be used to build hierarchies of entities.
      For example all job queue entities belonging to the same process
      may be placed in a higher level entity and scheduled against other
      process entities.
      Entities take turns emitting jobs from their job queue to the
      corresponding hardware ring, in accordance with the scheduler policy.

      drm/amd: Add CGS interfaces

      CGS (Common Graphics Services) is an AMD cross component
      abstraction layer to designed to better encapsulate
      specific IP block drivers so different teams can effectively
      work on differnet IP block drivers independently. It provides
      a common interface for things like accessing registers,
      allocating GPU memory, and registering interrupt sources.
      The plan is to eventually move more and more IP drivers to
      this interface.  The first user is the ACP IP driver.

      regulator: core: Define regulator_set_voltage_triplet()

      Voltage tolerance isn't necessarily same on both sides of the target
      voltage and regulator_set_voltage_tol() wouldn't be suitable in such
      cases.

      Add another routine regulator_set_voltage_triplet(), which accepts
      target, min and max voltages as arguments.

      This first tries to set the voltage between the target voltage and the
      upper limit, then fall back on the full range. The idea behind this is
      to set regulator's voltage as close to the target voltage, as possible.

      Based on regulator_set_voltage_tol().

      workqueue: fix some docbook warnings

      There are some errors in the docbook comments in workqueue.h that cause
      warnings when the docs are built; this only recently came to light because
      these comments were not used until now.  Fix the comments to make the
      warnings go away.

      The "args..." "fix" is a hack.  kerneldoc doesn't deal properly with named
      variadic arguments in macros, so all I've really achieved here is to make
      it shut up.  Fixing kerneldoc will have to wait for more time.

      Merge branch 'iff_no_queue'

      Phil Sutter says:

      ====================
      net: introduce IFF_NO_QUEUE as successor of zero tx_queue_len

      This series adds a new private net_device flag indicating that a device 
may
      (and probably should) be used without a queueing discipline attached to 
it.
      This is already common practice for many virtual device types like e.g.
      loopback, VLAN (802.1Q) or bridges (802.1D). The reason for this is that 
these
      devices lack an underlying layer which could impose back pressure and 
therefore
      making a TX queue necessary to not slow down senders.

      Up to now, drivers being aware of the above applying to them set
      dev->tx_queue_len to zero to indicate no qdisc should be attached to the
      interface they drive and the kernel reacts upon this by assigning the noop
      qdisc instead of the default pfifo_fast. This implicit agreement though 
leads
      to an inconvenient situation once a user tries to attach a real qdisc to 
these
      devices, as the formerly special tx_queue_len value becomes a regular one,
      limiting the queue to zero packets and thus prevents any TX from 
happening. To
      overcome this, practically all qdisc implementations intercept and 
sanitize the
      malicious value.

      With this series applied, drivers may signal the lack of need for a qdisc
      without having to tamper with tx_queue_len, making fallbacks in qdiscs and
      caveats in userspace unnecessary.

      Upon upstream acceptance, this series will be followed up by a set of 
patches
      converting device drivers, adding a warning so out-of-tree driver authors 
get
      aware of this change and dropping all special handling of tx_queue_len in
      net/sched/.

      NFS: Don't let the ctime override attribute barriers.

      Chuck reports seeing cases where a GETATTR that happens to race
      with an asynchronous WRITE is overriding the file size, despite
      the attribute barrier being set by the writeback code.

      The culprit turns out to be the check in nfs_ctime_need_update(),
      which sees that the ctime is newer than the cached ctime, and
      assumes that it is safe to override the attribute barrier.
      This patch removes that override, and ensures that attribute
      barriers are always respected.

      The current_kernel_time() is not year 2038 safe on 32bit systems
      since it returns a timespec value. Introduce current_kernel_time64()
      which returns a timespec64 value.

      time: Add the common weak version of update_persistent_clock()

      The weak update_persistent_clock64() calls update_persistent_clock(),
      if the architecture defines an update_persistent_clock64() to replace
      and remove its update_persistent_clock() version, when building the
      kernel the linker will throw an undefined symbol error, that is, any
      arch that switches to update_persistent_clock64() will have this issue.

      To solve the issue, we add the common weak update_persistent_clock().

      time: Always make sure wall_to_monotonic isn't positive

      Two issues were found on an IMX6 development board without an
      enabled RTC device(resulting in the boot time and monotonic
      time being initialized to 0).

      Issue 1:exportfs -a generate:
             "exportfs: /opt/nfs/arm does not support NFS export"
      Issue 2:cat /proc/stat:
             "btime 4294967236"

      The same issues can be reproduced on x86 after running the
      following code:
        int main(void)
        {
            struct timeval val;
            int ret;

            val.tv_sec = 0;
            val.tv_usec = 0;
            ret = settimeofday(&val, NULL);
            return 0;
        }

      Two issues are different symptoms of same problem:
      The reason is a positive wall_to_monotonic pushes boot time back
      to the time before Epoch, and getboottime will return negative
      value.

      In symptom 1:
                negative boot time cause get_expiry() to overflow time_t
                when input expire time is 2147483647, then cache_flush()
                always clears entries just added in ip_map_parse.
      In symptom 2:
                show_stat() uses "unsigned long" to print negative btime
                value returned by getboottime.

      This patch fix the problem by prohibiting time from being set to a value 
which
      would cause a negative boot time. As a result one can't set the 
CLOCK_REALTIME
      time prior to (1970 + system uptime).

  Date:   Thu Jun 25 14:13:55 2015 +0200

      time: Fix nanosecond file time rounding in timespec_trunc()

      timespec_trunc() avoids rounding if granularity <= nanoseconds-per-jiffie
      (or TICK_NSEC). This optimization assumes that:

       1. current_kernel_time().tv_nsec is already rounded to TICK_NSEC (i.e.
          with HZ=1000 you'd get 1000000, 2000000, 3000000... but never 
1000001).
          This is no longer true (probably since hrtimers introduced in 2.6.16).

       2. TICK_NSEC is evenly divisible by all possible granularities. This may
          be true for HZ=100, 250, 1000, but obviously not for HZ=300 /
          TICK_NSEC=3333333 (introduced in 2.6.20).

      Thus, sub-second portions of in-core file times are not rounded to on-disk
      granularity. I.e. file times may change when the inode is re-read from 
disk
      or when the file system is remounted.

      This affects all file systems with file time granularities > 1 ns and < 
1s,
      e.g. CEPH (1000 ns), UDF (1000 ns), CIFS (100 ns), NTFS (100 ns) and FUSE
      (configurable from user mode via struct fuse_init_out.time_gran).

      Steps to reproduce with e.g. UDF:

        $ dd if=/dev/zero of=udfdisk count=10000 && mkudffs udfdisk
        $ mkdir udf && mount udfdisk udf
        $ touch udf/test && stat -c %y udf/test
        2015-06-09 10:22:56.130006767 +0200
        $ umount udf && mount udfdisk udf
        $ stat -c %y udf/test
        2015-06-09 10:22:56.130006000 +0200

      Remounting truncates the mtime to 1 µs.

      Fix the rounding in timespec_trunc() and update the documentation.

      timespec_trunc() is exclusively used to calculate inode's [acm]time 
(mostly
      via current_fs_time()), and always with super_block.s_time_gran as second
      argument. So this can safely be changed without side effects.

      Note: This does _not_ fix the issue for FAT's 2 second mtime resolution,
      as super_block.s_time_gran isn't prepared to handle different ctime /
      mtime / atime resolutions nor resolutions > 1 second.

      timer_list: Add the base offset so remaining nsecs are accurate for non 
monotonic timers

      I noticed for non-monotonic timers in timer_list, some of the
      output looked a little confusing.

      For example:
       #1: <0000000000000000>, posix_timer_fn, S:01, hrtimer_start_range_ns, 
leap-a-day/2360
       # expires at 1434412800000000000-1434412800000000000 nsecs [in 
1434410725062375469 to 1434410725062375469 nsecs]

      You'll note the relative time till the expiration "[in xxx to
      yyy nsecs]" is incorrect. This is because its printing the delta
      between CLOCK_MONOTONIC time to the CLOCK_REALTIME expiration.

      This patch fixes this issue by adding the clock offset to the
      "now" time which we use to calculate the delta.

      SUNRPC: Fix a thinko in xs_connect()

      It is rather pointless to test the value of transport->inet after
      calling xs_reset_transport(), since it will always be zero, and
      so we will never see any exponential back off behaviour.
      Also don't force early connections for SOFTCONN tasks. If the server
      disconnects us, we should respect the exponential backoff.

      We should ensure that we always set the pgio_header's error field
      if a READ or WRITE RPC call returns an error. The current code depends

      ASoC: mediatek: Remove AIF widgets for backend DAIs

      DAPM core already creates widgets for DAIs. It is not necessary
      to declare them by SND_SOC_DAPM_AIF_IN/SND_SOC_DAPM_AIF_OUT.
      Furthermore, original codes use backend DAI's stream name to be the AIF
      widget name. It causes the same widget to be created twice, and after
      commit 92fa12426741 ("ASoC: dapm: Add new widgets to the end of the
      widget list") the first created widget (by snd_soc_dapm_new_controls)
      is used, not the 2nd created one (by snd_soc_dapm_new_dai_widgets),

      bnx2: Fix bandwidth allocation for some MF modes

      Management firmware tells driver in case bandwidth configuration for
      a specific function exists, but [regretably] the same field has different
      meanings depending on the multi-function mode - it can either be
      a percentile value or an actual speed.

      For newer multi-function modes current logic is incorrect -
      driver understands values as actual speeds instead of percentages,
      causing the resulting chip configuration to be incorrect.

      ath10k: refactor phyerr event handlers

      Existing phyerr event handlers directly uses phyerr header format
      (ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
      exactly on how firmware packs it. This is the problem in 10.4 fw
      specific phyerr event handling where it uses different phyerror
      header format. Before adding 10.4 specific handler, little bit of
      refactor is done in existing phyerr handlers.

      Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
      struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
      firmware specific header format in the code. So that firmware specific
      phyerror handlers can populate values to abstracted structures and
      the following code can use abstracted struct for further operation.

      .pull_phyerr_hdr is added newly to pull common phyerr header info
      like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
      handler is changed and called to parse every sub phyerrs in the event.

      Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

      pwm-pca9685: Support changing the output frequency

      Previously, period_ns and duty_ns were only used to determine the
      ratio of ON and OFF time, the default frequency of 200 Hz was never
      changed.
      The PCA9685 however is capable of changing the PWM output frequency,
      which is expected when changing the period.

      This patch configures the prescaler accordingly, using the formula
      and notes provided in the PCA9685 datasheet.
      Bounds checking for the minimum and maximum frequencies, last updated
      in revision v.4 of said datasheet, is also added.

      The prescaler is only touched if the period changed, because we have to
      put the chip into sleep mode to unlock the prescale register.
      If it is changed, the PWM output frequency changes for all outputs,
      because there is one prescaler per chip. This is documented in the
      PCA9685 datasheet and in the comments.

      If the duty cycle is not changed at the same time as the period, then
      we restart the PWM output using the duty cycle to period ratio from
      before the period change.
      When using LEDs for example, previously set brightness levels stay the
      same when the frequency changes.

      pwm-pca9685: Fix several driver bugs

      Problems:
      - When duty_ns == period_ns, the full OFF bit was not cleared and the
        PWM output of the PCA9685 stayed off.
      - When duty_ns == period_ns and the catch-all channel was used, the
        ALL_LED_OFF_L register was not cleared.
      - The full ON bit was not cleared when setting the OFF time, therefore
        the exact OFF time was ignored when setting a duty_ns < period_ns

      Solution: Clear both OFF registers when setting full ON and clear the
      full ON bit when changing the OFF registers.

      nbd: Fix timeout detection

      At the moment the nbd timeout just detects hanging tcp operations. This
      is not enough to detect a hanging or bad connection as expected of a
      timeout.

      This patch redesigns the timeout detection to include some more cases.
      The timeout is now in relation to replies from the server. If the server
      does not send replies within the timeout the connection will be shut
      down.

      The patch adds a continous timer 'timeout_timer' that is setup in one of
      two cases:
       - The request list is empty and we are sending the first request out to
         the server. We want to have a reply within the given timeout,
         otherwise we consider the connection to be dead.
       - A server response was received. This means the server is still
         communicating with us. The timer is reset to the timeout value.

      The timer is not stopped if the list becomes empty. It will just trigger
      a timeout which will directly leave the handling routine again as the
      request list is empty.

      The whole patch does not use any additional explicit locking. The
      list_empty() calls are safe to be used concurrently. The timer is locked
      internally as we just use mod_timer and del_timer_sync().

      The patch is based on the idea of Michal Belczyk with a previous
      different implementation.

      pwm: kona: Modify settings application sequence

      Update the driver so that settings are applied in accordance with the
      most recent version of the hardware spec.  The revised sequence clears
      the trigger bit, waits 400ns, writes settings, sets the trigger bit,
      and waits another 400ns.  This corrects an issue where occasionally a
      requested change was not properly reflected in the PWM output.

      scatterlist: allow limited chaining without ARCH_HAS_SG_CHAIN

      There are a couple of uses of struct scatterlist that never go to
      the dma_map_sg() helper and thus don't care about ARCH_HAS_SG_CHAIN
      which indicates that we can map chained S/G list.

      The most important one is the crypto code, which currently has
      to open code a few helpers to always allow chaining.  This patch
      removes a few #ifdef ARCH_HAS_SG_CHAIN statements so that we can
      switch the crypto code to these common helpers.

      perf tools: Take Intel PT into use

      To record an AUX area, the weak function auxtrace_record__init() must be
      implemented.

      Equally to decode an AUX area, the AUX area tracing type must be added
      to the perf_event__process_auxtrace_info() function.

      This patch makes those two changes plus hooks up default config for the
      intel_pt PMU.  Also some brief documentation is provided for using the
      tools with intel_pt.

      perf tools: Add Intel PT support

      Add support for Intel Processor Trace.

      Intel PT support fits within the new auxtrace infrastructure.  Recording
      is supporting by identifying the Intel PT PMU, parsing options and
      setting up events.

      Decoding is supported by queuing up trace data by cpu or thread and then
      decoding synchronously delivering synthesized event samples into the
      session processing for tools to consume.

      perf tools: Add Intel PT decoder

      Add support for decoding an Intel Processor Trace.

      Intel PT trace data must be 'decoded' which involves walking the object
      code and matching the trace data packets.

      The decoder requests a buffer of binary data via a get_trace()
      call-back, which it decodes using instruction information which it gets
      via another call-back walk_insn().

      The log file name is "intel_pt.log" and is opened in the current
      directory.  The log contains a record of all packets and instructions
      decoded and can get very large (10 MB would be a small one).

      perf tools: Add Intel PT instruction decoder

      Add support for decoding instructions for Intel Processor Trace.  The
      kernel x86 instruction decoder is copied for this.

      This essentially provides intel_pt_get_insn() which takes a binary
      buffer, uses the kernel's x86 instruction decoder to get details of the
      instruction and then categorizes it for consumption by an Intel PT
      decoder.

      Also change the 'saddr' variable from 'unsigned long' to 'u64'

      perf script: Initialize callchain_param.record_mode

      Milian Wolff reported non functional DWARF unwind under perf script. The
      reason is that perf script does not properly configure
      callchain_param.record_mode, which is needed by unwind code.

      Stealing the code from report and leaving the place for more
      initialization code in a hope we could merge it with

      ath10k: fix invalid survey reporting for QCA99X0

      There are three WMI_CHAN_INFO events reported per channel
      in QCA99X0 firmware. First one is a notification at the begining
      of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
      second one is a notification at the end of the dwell time with cmd_flag
      CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
      with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
      the channel. Since there is a new state before the completion, the handler
      is to fixed so that the counts are deducted from the ones reported with
      CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.
      Without this fix there will be lots of 0 msecs reported as active
      and busy time.

      ath10k: wake up queue upon vif creation

      Vif's vdev_id is used as queue number. However due
      to the tx pausing design in ath10k it was possible
      for a new interface to be created with its tx
      queue stopped (via ieee80211_stop_queues). This
      could in turn leave the interface inoperable until
      ath10k_mac_tx_unlock() was called.

      This problem only affected multi-vif scenarios when
      new interfaces were created some time later after
      other interfaces have been running for some time
      and had Tx queue full at some point prior.

      Possible manifestation of the bug was
      authentication timeout for a client vif.

      gpiolib: irqchip: use different lockdep class for each gpio irqchip

      Since IRQ chip helpers were introduced drivers lose ability to
      register separate lockdep classes for each registered GPIO IRQ
      chip and the gpiolib now is using shared lockdep class for
      all GPIO IRQ chips (gpiochip_irq_lock_class).
      As result, lockdep will produce warning when there are min two
      stacked GPIO chips and all of them are interrupt controllers.

      HW configuration which generates lockdep warning (TI dra7-evm):

      [SOC GPIO bankA.gpioX]
        <- irq - [pcf875x.gpioY]
                  <- irq - DevZ.enable_irq_wake(pcf_gpioY_irq);
      The issue was reported in [1] and discussed [2].

      mmc: dw_mmc: add quirk for broken data transfer over scheme

      This patch add a new quirk to add a s/w timer to notify the driver
      to terminate current transfer and report a data timeout to the core,
      if DTO interrupt does NOT come within the given time.

      dw_mmc call mmc_request_done func to finish transfer depends on
      DTO interrupt. If DTO interrupt does not come in sending data state,
      the current transfer will be blocked.

      We got the reply from synopsys:
      There are two counters but both use the same value of [31:8] bits.
      Data timeout counter doesn't wait for stop clock and you should get
      DRTO even when the clock is not stopped.
      Host Starvation timeout counter is triggered with stop clock condition.

      This means that host should get DRTO and DTO interrupt.

      But this case really exists, when driver reads tuning data from
      card on RK3288-pink2 board. I measured waveforms by oscilloscope
      and found that card clock was always on and data lines were always
      holded high level in sending data state.

      There are two possibility that data over interrupt doesn't come in
      reading data state on RK3X SoCs:
      - get command done interrupt, but doesn't get any data-related interrupt.
      - get data error interrupt, but doesn't get data over interrupt.

      mmc: dw_mmc: fix pio mode when internal dmac is enabled

      The dw_mci_init_dma() may decide to not use dma, but pio instead, caused
      by things like wrong dma settings in the system.

      Till now the code dw_mci_init_slot() always assumed that dma is available
      when CONFIG_MMC_DW_IDMAC was defined, ignoring the host->use_dma var
      set during dma init.

      So when now the dma init failed for whatever reason, the transfer sizes
      would still be set for dma transfers, especially including the maximum
      block-count calculated from host->ring_size and resulting in a

      [    4.991113] Internal error: Oops - BUG: 0 [#1] SMP ARM

      because host->ring_size is 0 in this case and the slot init code uses
      the wrong code to calculate the values.

      Fix this by selecting the correct calculations using the host->use_dma
      variable instead of the CONFIG_MMC_DW_IDMAC config option.

      mmc: dw_mmc: handle data blocks > than 4kB if IDMAC is used

      As per DW MobileStorage databook "each descriptor can transfer up to 4kB
      of data in chained mode", moreover buffer size that is put in "des1" is
      limited to 13 bits, i.e. for example on attempt to
      IDMAC_SET_BUFFER1_SIZE(desc, 8192) size value that's effectively written
      will be 0.

      On the platform with 8kB PAGE_SIZE I see dw_mmc gets data blocks in
      SG-list of 8kB size and that leads to unpredictable behavior of the
      SD/MMC controller.

      In particular on write to FAT partition of SD-card the controller will
      stuck in the middle of DMA transaction.

      Solution to the problem is simple - we need to pass large (> 4kB) data
      buffers to the controller via multiple descriptors. And that's what
      that change does.

      What's interesting I did try original driver on same platform but
      configured with 4kB PAGE_SIZE and may confirm that data blocks passed
      in SG-list to dw_mmc never exeed 4kB limit - that explains why nobody
      ever faced a problem I did.

      mmc: sdio: avoid using NULL sdio_irq_thread pointer

      For Freescale QorIQ LS1021AQDS board, there is a SDIO interrupt
      in the process of resume without inserting SD adapter because of
      some unknown issue. But the driver doesn't assign sdio_irq_thread
      pointer. This will block the resume of kernel. This patch is used
      to avoid using NULL sdio_irq_thread pointer.

      gpio/grgpio: fix deadlock in grgpio_irq_unmap()

      As reported by Alexey Khoroshilov:

          grgpio_irq_unmap() code looks quite suspicious regarding usage of
          priv->bgc.lock spinlock.

          It locks the spinlock in line 310:

        spin_lock_irqsave(&priv->bgc.lock, flags);

          and then it can call grgpio_set_imask() in line 317:

        grgpio_set_imask(priv, i, 0);

          But grgpio_set_imask() unconditionally locks the spinlock by itself.

      Fix this by moving the spinlock acquisition outside of
      grgpio_set_imask().

      Found by Linux Driver Verification project (linuxtesting.org).

      prevents an AP from proceeding until the BSP has set
      cpu_callout_mask, making "init_deasserted" {unnecessary}:

        BSP: <de-assert INIT>
        ...
        BSP: {set init_deasserted}
        AP: wait_for_master()
                set cpu_initialized_mask
                wait for cpu_callout_mask
        BSP: test cpu_initialized_mask
        BSP: set cpu_callout_mask
        AP: test cpu_callout_mask
        AP: {wait for init_deasserted}
        ...
        AP: <touch APIC>

      Deleting the {dead code} above is necessary to enable
      some parallelism in a future patch.

      x86/smpboot: Remove SIPI delays from cpu_up()

      MPS 1.4 example code shows the following required delays during processor
      on-lining:

        INIT
         udelay(10,000)
        SIPI
         udelay(200)
        SIPI
         udelay(200) /* Linux actually implements this as udelay(300) */

      Linux skips the udelay(10,000) on modern processors.
      This patch removes the udelay(200) after each SIPI
      on those same processors.

      All three legacy delays can be restored by the cmdline
      "cpu_init_udelay=10000".

      As measured by analyze_suspend.py, this patch speeds
      processor resume time on my desktop from 2.4ms to 1.8ms, per AP.

      x86/smpboot: Remove udelay(100) when polling cpu_callin_map

      After the BSP sends INIT/SIPI/SIP to the AP and sees the AP
      in the cpu_initialized_map, it sets the AP loose via the
      cpu_callout_map, and waits for it via the cpu_callin_map.

      The BSP polls the cpu_callin_map with a udelay(100)
      and a schedule() in each iteration.

      The udelay(100) adds no value.

      For example, on my 4-CPU dekstop, the AP finishes
      cpu_callin() in under 70 usec and sets the cpu_callin_mask.
      The BSP, however, doesn't see that setting until over 30 usec
      later, because it was still running its udelay(100)
      when the AP finished.

      Deleting the udelay(100) in the cpu_callin_mask polling loop,
      saves from 0 to 100 usec per Application Processor.

      x86/smpboot: Remove udelay(100) when polling cpu_initialized_map

      After the BSP sends the APIC INIT/SIPI/SIPI to the AP,
      it waits for the AP to come up and indicate that it is alive
      by setting its own bit in the cpu_initialized_mask.

      Linux polls for up to 10 seconds for this to happen.
      Each polling loop has a udelay(100) and a call to schedule().

      The udelay(100) adds no value.

      For example, on my desktop, the BSP waits for the
      other 3 CPUs to come on line at boot for 305, 404, 405 usec.
      For resume from S3, it waits 317, 404, 405 usec.

      But when the udelay(100) is removed, the BSP waits
      305, 310, 306 for boot, and 305, 307, 306 for resume.

      So for both boot and resume, removing the udelay(100)
      speeds online by about 100us in 2 of 3 cases.

      Merge branch 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux 
into drm-next

      A couple of fixes from the previous pull request as well as gl3 support.
      There is one drm core change, an export of a previously private function.

      Take 2 implementing screen targets, this time with the fbdev code adjusted
      accordingly.

      Also there is an implementation of register-driven command buffers, that
      overrides the FIFO ring for command processing. It's needed for our 
upcoming
      hardware revision.

      drm/tegra: Changes for v4.3-rc1

      There are a bunch of non-critical fixes here that I've collected over
      the past few months, but the biggest part is Tegra210 support, in the
      DC, DSI and SOR/HDMI drivers.

      Also this finally restores DPMS with atomic mode-setting, something
      that has been broken since the conversion and which I had originally
      expected to take far less longer to fix.

      Summary:
      - Clean up HDMI and MIXER parts
      - Clean up legacy structures specific to Exynos DRM
        . This patch series removes existing exyons_drm_display and
          exynos_drm_encoder structures specific to Exynos DRM, and
          makes them to replace with common drm_encoder structure.
          With cleanup patch, we removes exynos_drm_encoder module.
      - Clean up gem, dmabuf and buffer modules
        . This patch series replaces existing Exynos DRM dmabuf codes
          with common drm prime ones, and embeds all codes of exynos_drm_buf
          into exynos_drm_gem module.
          With cleanup patch, we removes exynos_drm_buf and exynos_drm_dmabuf
          modules.
      - And some fixups.

      xtensa: implement fake NMI

      In case perf IRQ is the highest of the medium-level IRQs, and is alone
      on its level, it may be treated as NMI:
      - LOCKLEVEL is defined to be one level less than EXCM level,
      - IRQ masking never lowers current IRQ level,
      - new fake exception cause code, EXCCAUSE_MAPPED_NMI is assigned to that
        IRQ; new second level exception handler, do_nmi, assigned to it
        handles it as NMI,
      - atomic operations in configurations without s32c1i still need to mask
        all interrupts.

      xtensa: fix kernel register spilling

      call12 can't be safely used as the first call in the inline function,
      because the compiler does not extend the stack frame of the bounding
      function accordingly, which may result in corruption of local variables.

      If a call needs to be done, do call8 first followed by call12.

      For pure assembly code in _switch_to increase stack frame size of the
      bounding function.

      xtensa: implement counting and sampling perf events

      Xtensa Performance Monitor Module has up to 8 32 bit wide performance
      counters. Each counter may be enabled independently and can count any
      single type of hardware performance events. Event counting may be enabled
      and disabled globally (per PMM).
      Each counter has status register with bits indicating if the counter has
      been overflown and may be programmed to raise profiling IRQ on overflow.
      This IRQ is used to rewind counters and allow for counting more than 2^32
      samples for counting events and to report samples for sampling events.

      For more details see Tensilica Debug User's Guide, chapter 8
      "Performance monitor module".

      xtensa: keep exception/interrupt stack continuous

      Restore original a0 in the kernel exception stack frame. This way it
      looks like the frame that got interrupt/exception did alloca (copy a0 and
      a1 spilled under old stack to the new location as well) to save registers
      and then did a call to handler.
      The point where interrupt/exception was taken is not in the stack chain,
      only in pt_regs (call4 from that address can be simulated to keep it in
      the stack trace).

      scripts/kernel-doc: Adding cross-reference links to html documentation.

      Functions, Structs and Parameters definitions on kernel documentation
      are pure cosmetic, it only highlights the element.

      To ease the navigation in the documentation we should use <links> inside
      those tags so readers can easily jump between methods directly.

      This was discussed in 2014[1] and is implemented by getting a list
      of <refentries> from the DocBook XML to generate a database. Then it looks
      for <function>,<structnames> and <paramdef> tags that matches the ones in
      the database. As it only links existent references, no broken links are
      added.

      cxl: Plug irq_bitmap getting leaked in cxl_context

      This patch plugs the leak of irq_bitmap, allocated as part of
      initialization of cxl_context struct; during the call to
      afu_allocate_irqs. The bitmap is now release during the call to function
      afu_release_irqs.

      CONFIG_CXL_EEH is for CXL's EEH related code.

      Other drivers can depend on or #ifdef on this symbol to configure
      PERST behaviour, allowing CXL to participate in the EEH process.

      Convert omap_vout_uservirt_to_phys() to use get_vaddr_pfns() instead of
      hand made mapping of virtual address to physical address. Also the
      function leaked page reference from get_user_pages() so fix that by
      properly release the reference when omap_vout_buffer_release() is
      called.

      [media] mm: Provide new get_vaddr_frames() helper

      Provide new function get_vaddr_frames().  This function maps virtual
      addresses from given start and fills given array with page frame numbers 
of
      the corresponding pages. If given start belongs to a normal vma, the 
function
      grabs reference to each of the pages to pin them in memory. If start
      belongs to VM_IO | VM_PFNMAP vma, we don't touch page structures. Caller
      must make sure pfns aren't reused for anything else while he is using
      them.

      This function is created for various drivers to simplify handling of
      their buffers.

      [media] vb2: Push mmap_sem down to memops

      Currently vb2 core acquires mmap_sem just around call to
      __qbuf_userptr(). However since commit f035eb4e976ef5 (videobuf2: fix
      lockdep warning) it isn't necessary to acquire it so early as we no
      longer have to drop queue mutex before acquiring mmap_sem. So push
      acquisition of mmap_sem down into .get_userptr memop so that the
      semaphore is acquired for a shorter time and it is clearer what it is
      needed for.

      Note that we also need mmap_sem in .put_userptr memop since that ends up
      calling vb2_put_vma() which calls vma->vm_ops->close() which should be
      called with mmap_sem held. However we didn't hold mmap_sem in some code
      paths anyway (e.g. when called via vb2_ioctl_reqbufs() ->
      __vb2_queue_free() -> vb2_dma_sg_put_userptr()) and getting mmap_sem in
      put_userptr() introduces a lock inversion with queue->mmap_lock in the
      above mentioned call path.

      Luckily this whole locking mess will get resolved once we convert
      videobuf2 core to the new mm helper which avoids the need for mmap_sem
      in .put_userptr memop altogether.

      [media] sr030pc30: don't read a new pointer

      sr030pc30_get_fmt() can only succeed if both info->curr_win and
      info->curr_fmt are not NULL.

      If one of those vars are null, the curent code would call:
        ret = sr030pc30_set_params(sd);

      If the curr_win is null, it will return -EINVAL, as it would be
      expected. However, if curr_fmt is NULL, the function won't
      set it.

      The code will then try to read from it:

              mf->code        = info->curr_fmt->code;
              mf->colorspace  = info->curr_fmt->colorspace;

      with obviouly won't work.

      This got reported by smatch:

      iwlwifi: convert hex_dump_to_buffer() to %*ph

      There is no need to use hex_dump_to_buffer() in the cases like this:

<= 16 */
        sprintf("%s\n", outbuf);

      since it maybe easily converted to simple:

        sprintf("%*ph\n", len, buf);

      Note: it seems in one case the output is groupped by 2 bytes and looks 
like a

      ALSA: usb: handle descriptor with SYNC_NONE illegal value

      The M-Audio Transit exposes an interface with a SYNC_NONE attribute.
      This is not a valid value according to the USB audio classspec. However
      there is a sync endpoint associated to this record. Changing the logic to
      try to use this sync endpoint allows for seamless transitions between
      altset 2 and altset 3. If any errors happen, the behavior remains the 
same.

      ALSA: usb: fix corrupted pointers due to interface setting change

      When a transition occurs between alternate settings that do not use the
      same synchronization method, the substream pointers were not reset.
      This prevents audio from being played during the second transition.

      Identified and tested with M-Audio Transit device
      (0763:2006 Midiman M-Audio Transit)

      Details of the issue:

      drm/exynos: remove exynos_drm_create_enc_conn()

      This functions was just hiding the encoder and connector creation in

      exynos_encoder ops had .create_connector() defined only because we were
      handing off the encoder and connector creation to
      exynos_drm_create_enc_conn(). Without this function we can directly call
      the create_connector function internally in the code, without the need of
      any vtable access.

      drm/exynos: use drm atomic state directly

      For some fields the use of struct exynos_drm_plane filled with data from
      the plane state just creates a source of duplicated information and
      overhead.  Here we change the crtc drivers to access the plane state
      directly simplifying the code by not relying on a exynos internal struct.

      drm/msm/dsi: Modify dsi manager bridge ops to work with external bridges

      The dsi bridge ops call drm_panel functions to set up the connected
      drm_panel. Add checks to make sure these aren't called when we're

      drm/msm/dsi: Allow dsi to connect to an external bridge

      There are platforms where the DSI output can be connected to another
      encoder bridge chip (DSI to HDMI, DSI to LVDS etc).

      Add support for external bridge support to the dsi driver. We assume that
      the external bridge chip would be of the type drm_bridge. The dsi driver's
      internal drm_bridge (msm_dsi->bridge) is linked to the external bridge's
      drm_bridge struct.

      In the case we're connected to an external bridge, we don't need to create
      and manage a connector within our driver, it's the bridge driver's
      responsibility to create one.

      v2:
      - Move the external bridge attaching stuff to dsi manager to make things
        cleaner.
      - Force the bridge to connect to a video mode encoder for now (the dsi
        mode flags may have not been populated by modeset_init)

      drm/msm/dsi: Create a helper to check if there is a connected device

      Create a helper msm_dsi_device_connected() which checks whether we have a
      device connected to the dsi host or not. This check gets messy when we
      have support external bridges too. Having an inline function makes it
      more legible.

      For now, the check only consists of msm_dsi->panel being non-NULL. Later,
      this will check if we have an external bridge or not.

      This helper isn't used in dsi_connector related code as that's specific
      to only when a drm_panel is connected.

      drm/msm: dsi host: Use device graph parsing to parse connected panel

      The dsi host looks for the connected panel node by parsing for a child
      named 'panel'. This hierarchy isn't very flexible. The connected
      panel is forced to be a child to the dsi host, and hence, a mipi dsi
      device. This isn't suitable for dsi devices that don't use mipi dsi
      as their control bus.

      Follow the of_graph approach of creating ports and endpoints to
      represent the connections between the dsi host and the panel connected
      to it. In our case, the dsi host will only have one output port, linked
      to the panel's input port.

      Update DT binding documentation with device graph usage info.

      v3:
      - Fix return value checks of of_graph_* calls.
      - Don't make port a mandatory DT property
      - Fix defer check when no panel node specified
      - Rename parse_dt func to align with other dsi_host funcs

      drm/msm/dsi: Rename *dual panel* to *dual DSI*

      The current term of *dual panel* in DSI driver code causes confusion.
      It is supposed to indicate the panel using two DSI links. Rename it
      to *dual DSI*.

      drm/msm/dsi: Update source PLL selection in DSI PHY

      The source PLL to be used by each DSI PHY should be decided by
      DSI manager based on dual DSI information, while the register
      programming to select PLL is different from one type of PHY to
      another. This change adds the H/W difference to PHY configuration
      and updates the interface between DSI manager and PHY.

      With this change, PLL selection can be supported on different
      targets.

      the first lowpan interface and deregister it at the last interface. This
      done by open_count variable which is protected by rtnl.

      Additional do a quiet fix by adding dev_put(real_dev) when netdev

      blk-mq: fix race between timeout and freeing request

      Inside timeout handler, blk_mq_tag_to_rq() is called
      to retrieve the request from one tag. This way is obviously
      wrong because the request can be freed any time and some
      fiedds of the request can't be trusted, then kernel oops
      might be triggered[1].

      Currently wrt. blk_mq_tag_to_rq(), the only special case is
      that the flush request can share same tag with the request
      cloned from, and the two requests can't be active at the same
      time, so this patch fixes the above issue by updating tags->rqs[tag]
      with the active request(either flush rq or the request cloned
      from) of the tag.

      Also blk_mq_tag_to_rq() gets much simplified with this patch.

      Given blk_mq_tag_to_rq() is mainly for drivers and the caller must
      make sure the request can't be freed, so in bt_for_each() this
      helper is replaced with tags->rqs[tag].

      blk-mq: fix buffer overflow when reading sysfs file of 'pending'

      There may be lots of pending requests so that the buffer of PAGE_SIZE
      can't hold them at all.

      One typical example is scsi-mq, the queue depth(.can_queue) of
      scsi_host and blk-mq is quite big but scsi_device's queue_depth
      is a bit small(.cmd_per_lun), then it is quite easy to have lots
      of pending requests in hw queue.

      This patch fixes the following warning and the related memory
      destruction.

      The second check is unnecessary.

      I've simplified this code by moving the "if (!*bh)" checks around.  Also
      Andreas Dilger says we should probably print a warning if sb_getblk()
      fails.

      [ Restructured the code so that we print a warning message as well if
        the mmp block doesn't check out, and to print the error code to
        disambiguate between the error cases.  - TYT ]

      ext4: don't manipulate recovery flag when freezing no-journal fs

      At some point along this sequence of changes:

      f6e63f9 ext4: fold ext4_nojournal_sops into ext4_sops
      bb04457 ext4: support freezing ext2 (nojournal) file systems
      9ca9238 ext4: Use separate super_operations structure for no_journal 
filesystems

      ext4 started setting needs_recovery on filesystems without journals
      when they are unfrozen.  This makes no sense, and in fact confuses
      blkid to the point where it doesn't recognize the filesystem at all.

      (freeze ext2; unfreeze ext2; run blkid; see no output; run dumpe2fs,
      see needs_recovery set on fs w/ no journal).

      To fix this, don't manipulate the INCOMPAT_RECOVER feature on
      filesystems without journals.

  commit 8129ed29644bf56ed17ec1bbbeed5c568b43d6a0
  Author: Oleg Nesterov <oleg@xxxxxxxxxx>
  Date:   Tue Aug 11 17:05:04 2015 +0200

      change sb_writers to use percpu_rw_semaphore

      We can remove everything from struct sb_writers except frozen
      and add the array of percpu_rw_semaphore's instead.

      This patch doesn't remove sb_writers->wait_unfrozen yet, we keep
      it for get_super_thawed(). We will probably remove it later.

      This change tries to address the following problems:

        - Firstly, __sb_start_write() looks simply buggy. It does
          __sb_end_write() if it sees ->frozen, but if it migrates
          to another CPU before percpu_counter_dec(), sb_wait_write()
          can wrongly succeed if there is another task which holds
          the same "semaphore": sb_wait_write() can miss the result
          of the previous percpu_counter_inc() but see the result
          of this percpu_counter_dec().

        - As Dave Hansen reports, it is suboptimal. The trivial
          microbenchmark that writes to a tmpfs file in a loop runs
          12% faster if we change this code to rely on RCU and kill
          the memory barriers.

        - This code doesn't look simple. It would be better to rely
          on the generic locking code.

          According to Dave, this change adds the same performance
          improvement.

      Note: with this change both freeze_super() and thaw_super() will do
      synchronize_sched_expedited() 3 times. This is just ugly. But:

        - This will be "fixed" by the rcu_sync changes we are going
          to merge. After that freeze_super()->percpu_down_write()
          will use synchronize_sched(), and thaw_super() won't use
          synchronize() at all.

          This doesn't need any changes in fs/super.c.

        - Once we merge rcu_sync changes, we can also change super.c
          so that all wb_write->rw_sem's will share the single ->rss
          in struct sb_writes, then freeze_super() will need only one
          synchronize_sched().

      shift percpu_counter_destroy() into destroy_super_work()

      Of course, this patch is ugly as hell. It will be (partially)
      reverted later. We add it to ensure that other WIP changes in
      percpu_rw_semaphore won't break fs/super.c.

      We do not even need this change right now, percpu_free_rwsem()
      is fine in atomic context. But we are going to change this, it
      will be might_sleep() after we merge the rcu_sync() patches.

      And even after that we do not really need destroy_super_work(),
      we will kill it in any case. Instead, destroy_super_rcu() should
      just check that rss->cb_state == CB_IDLE and do call_rcu() again
      in the (very unlikely) case this is not true.

      So this is just the temporary kludge which helps us to avoid the
      conflicts with the changes which will be (hopefully) routed via
      rcu tree.

      document rwsem_release() in sb_wait_write()

      Not only we need to avoid the warning from lockdep_sys_exit(), the
      caller of freeze_super() can never release this lock. Another thread
      can do this, so there is another reason for rwsem_release().

      fix the broken lockdep logic in __sb_start_write()

      1. wait_event(frozen < level) without rwsem_acquire_read() is just
         wrong from lockdep perspective. If we are going to deadlock
         because the caller is buggy, lockdep can't detect this problem.

      2. __sb_start_write() can race with thaw_super() + freeze_super(),
         and after "goto retry" the 2nd  acquire_freeze_lock() is wrong.

      3. The "tell lockdep we are doing trylock" hack doesn't look nice.

         I think this is correct, but this logic should be more explicit.
         Yes, the recursive read_lock() is fine if we hold the lock on a
         higher level. But we do not need to fool lockdep. If we can not
         deadlock in this case then try-lock must not fail and we can use
         use wait == F throughout this code.

      Note: as Dave Chinner explains, the "trylock" hack and the fat comment
      can be probably removed. But this needs a separate change and it will
      be trivial: just kill __sb_start_write() and rename do_sb_start_write()
      back to __sb_start_write().

      staging: wilc1000: clarify the argument type

      This patch replaces the void pointer type in the host interface
      functions which process the message from host thread by the real data
      type, tstrWILC_WFIDrv because the void pointer type as the arguments
      is not clear and concise. In addition, typecasting to the void pointer
      type is removed becasue it is not necessary.

      staging: wilc1000: replace WILC_WFIDrvHandle by tstrWILC_WFIDrv

      The structure, WILC_WFIDrvHandle is used to save the pointer address
      for the driver handler which is used throughout the driver but it's
      not easy to understand what it means. In addition, it doesn't support
      the 64 bit machine and also causes the warnings for the 64 bit build.

      This patch replaces the WILC_WFIDrvHandle by the tstrWILC_WFIDrv
      because the tstrWILC_WFIDrv is real structure to represent the driver
      handler and reduces the 64 bit compile warnings. Also, typecasting to
      WILC_WFIDrvHandle is not needed by using tstrWILC_WFIDrv as is.

      This patch uses the following semantic patch to find such an instance
      where NULL check is present before kfree.

      // <smpl>
      @@ expression E; @@
      - if (E != NULL) { kfree(E); }
      + kfree(E);
      @@ expression E; @@
      - if (E != NULL) { kfree(E); E = NULL; }
      + kfree(E);
      + E = NULL;
      // </smpl>smpl>

      staging: comedi: adl_pci7x3x: fix digital output on PCI-7230

      The "adl_pci7x3x" driver replaced the "adl_pci7230" and "adl_pci7432"
      drivers in commits 8f567c373c4b ("staging: comedi: new adl_pci7x3x
      driver") and 657f77d173d3 ("staging: comedi: remove adl_pci7230 and
      adl_pci7432 drivers").  Although the new driver code agrees with the
      user manuals for the respective boards, digital outputs stopped working
      on the PCI-7230.  This has 16 digital output channels and the previous
      adl_pci7230 driver shifted the 16 bit output state left by 16 bits
      before writing to the hardware register.  The new adl_pci7x3x driver
      doesn't do that.  Fix it in `adl_pci7x3x_do_insn_bits()` by checking
      for the special case of the subdevice having only 16 channels and
      duplicating the 16 bit output state into both halves of the 32-bit
      register.  That should work both for what the board actually does and
      for what the user manual says it should do.

      This function is only called by comedi_dev_get_from_minor() and the 
'minor'
      value will always be < COMEDI_NUM_BOARD_MINORS. Remove the unnecessary
      BUG_ON().

      Drivers should not crash the kernel.

      This function is only called by comedi_device_detach_cleanup() and the
      s->minor will always be valid or the device wouldn't have attached in
      the first place.

      Leave the checks for safety in accessing the comedi_subdevice_minor_table
      array but remove the BUG_ON() calls.

      The BUG_ON() checks in this function are not necessary.

      comedi_cleanup_board_minors() clears all the entries in the
      comedi_board_minor_table array and will call comedi_device_cleanup()
      for all attached devices. comedi_device_cleanup() will then
      clear the entries in the comedi_subdevice_minor_table array with
      comedi_free_subdevice_minor().

      Remove the BUG_ON(), drivers should not crash the kernel.

      The BUG_ON() checks in comedi_subdevice_from_minor() and

      Coverity reports a possible Out-of-bounds access (ARRAY_VS_SINGLETON)
      with the 'const u8 *port' parameter passed to ni6501_port_command().
      This param is an actual array for the SET_PORT_DIR operation, called
      by ni6501_dio_insn_config(). But for the WRITE_PORT and READ_PORT
      operations, called by ni6501_dio_insn_bits(), it is just the address
      of an u8 local variable.

      Fix the coverity issue by changing the parameter to an unsigned int
      and pass the raw values from ni6501_dio_insn_config() and
      ni6501_dio_insn_bits(). ni6501_port_command() then handles the masking

      For consistency, change the access of the 'bitmap' parameter from an
      array access to a pointer operation.

      serial: imx: save and restore context in the suspend path

      This change teaches the imx serial driver to save its
      context and restore it across suspend and resume path.
      To do so, it introduces serial_imx_restore_context()
      and serial_imx_save_context() functions. They use
      a shadow set of registers to save key registers
      and restore them accordingly. These functions can
      be reused on other situations, when the device
      context is lost.

      serial: imx: remove unbalanced clk_prepare

      The current code attempts to prepare clk_per and clk_ipg
      before using the device. However, the result is an extra
      prepare call on each clock. Here is the output of uart
      clocks (only uart enabled and used as console):

      $  grep uart /sys/kernel/debug/clk/clk_summary
       uart_serial           1            2    80000000          0 0

      serial: mxs-auart: keep the AUART unit in reset state when not in use

      Whenever the UART device driver gets closed from userland, the driver
      disables the UART unit and then stops the clocks to save power.

      The bit which disabled the UART unit is described as:

      Â "UART Enable. If this bit is set to 1, the UART is enabled. Data
        transmission and reception occurs for the UART signals. When the
        UART is disabled in the middle of transmission or reception, it
        completes the current character before stopping."

      The important part is the "it completes the current character". Whenever
      a reception is ongoing when the UART gets disabled (including the clock
      off) the statemachine freezes and "remembers" this state on the next
      open() when re-enabling the unit's clock.

      In this case we end up receiving an additional bogus character
      immediately.

      The solution in this change is to switch the AUART unit into its reset
      state on close() and only release it from its reset state on the next
      open().

      Note: when the unit is also used as system console it is always 'in use',
      so we cannot reset it on close().

      usb: patches for v4.3 merge window

      New support for Allwinne SoC on the MUSB driver has been added to the 
list of
      glue layers. MUSB also got support for building all DMA engines in one 
binary;
      this will be great for distros.

      DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely 
on
      tracing to debug DWC3. There was also a fix for memory corruption with 
EP0 when
      maxpacket size transfers are > 512 bytes.

      Robert's EP capabilities flags is making EP selection a lot simpler. UDCs 
are
      now required to set these flags up when adding endpoints to the framework.

      Other than these, we have the usual set of miscelaneous cleanups and minor
      fixes.

      batman-adv: Fix potential synchronization issues in mcast tvlv handler

      So far the mcast tvlv handler did not anticipate the processing of
      multiple incoming OGMs from the same originator at the same time. This
      can lead to various issues:

      * Broken refcounting: For instance two mcast handlers might both assume
        that an originator just got multicast capabilities and will together
        wrongly decrease mcast.num_disabled by two, potentially leading to
        an integer underflow.

      * Potential kernel panic on hlist_del_rcu(): Two mcast handlers might
        one after another try to do an
        hlist_del_rcu(&orig->mcast_want_all_*_node). The second one will
        cause memory corruption / crashes.
        (Reported by: Sven Eckelmann <sven@xxxxxxxxxxxxx>)

      Right in the beginning the code path makes assumptions about the current
      multicast related state of an originator and bases all updates on that. 
The
      easiest and least error prune way to fix the issues in this case is to
      serialize multiple mcast handler invocations with a spinlock.

      drm/panel: simple: Add bus format for HannStar HSD070PWW1 LVDS panel

      The bus format both specifies the bpc and the way the individual bits get
      serialized into the 7 LVDS timeslots.

      While the is only one standard mapping for 6 bpc and so the driver could
      infer the bit mapping from the bpc alone, there are more options for the
      8 bpc case which makes specifiying the bus format mandatory.
      To keep things consistent across panels and to set a precedent for new
      panel additions add the proper bus format.

      regulator: core: Print at debug level on debugfs creation failure

      Failure to create a debugfs node is not an error, but we print a
      warning upon failure to create the node. Downgrade this to a
      debug printk so that we're quiet here. This allows multiple
      drivers to request a CPU's regulator so that CPUfreq and AVSish
      drivers can coexist.

      The downside of this approach is that whoever gets to debugfs first
      the others who come later to not have any debugfs attributes associated
      with them.

      spi: bcm2835: set up spi-mode before asserting cs-gpio

      When using reverse polarity for clock (spi-cpol) on a device
      the clock line gets altered after chip-select has been asserted
      resulting in an additional clock beat, which confuses hardware.

      This did not show when using native-CS, as the same register
      is used to control cs as well as polarity, so the changes came
      into effect at the same time. Unfortunately this is not true
      with gpio-cs.

      To avoid this situation this patch moves the setup of polarity
      (spi-cpol and spi-cpha) outside of the chip-select into
      prepare_message, which is run prior to asserting chip-select.

      Also fixes resetting 3-wire mode after use of rx-mode, so that
      a 3-Wire sequence TX, RX, TX works as well (right now it runs
      TX, RX, RX instead)

      libnvdimm, btt: write and validate parent_uuid

      When a BTT is instantiated on a namespace it must validate the namespace
      uuid matches the 'parent_uuid' stored in the btt superblock. This
      property enforces that changing the namespace UUID invalidates all
      former BTT instances on that storage. For "IO namespaces" that don't
      have a label or UUID, the parent_uuid is set to zero, and this
      validation is skipped. For such cases, old BTTs have to be invalidated
      by forcing the namespace to raw mode, and overwriting the BTT info
      blocks.

      arch: introduce memremap()

      Existing users of ioremap_cache() are mapping memory that is known in
      advance to not have i/o side effects.  These users are forced to cast
      away the __iomem annotation, or otherwise neglect to fix the sparse
      errors thrown when dereferencing pointers to this memory.  Provide
      memremap() as a non __iomem annotated ioremap_*() in the case when
      ioremap is otherwise a pointer to cacheable memory. Empirically,
      ioremap_<cacheable-type>() call sites are seeking memory-like semantics
      (e.g.  speculative reads, and prefetching permitted).

      memremap() is a break from the ioremap implementation pattern of adding
      a new memremap_<type>() for each mapping type and having silent
      compatibility fall backs.  Instead, the implementation defines flags
      that are passed to the central memremap() and if a mapping type is not
      supported by an arch memremap returns NULL.

      We introduce a memremap prototype as a trivial wrapper of
      ioremap_cache() and ioremap_wt().  Later, once all ioremap_cache() and
      ioremap_wt() usage has been removed from drivers we teach archs to
      implement arch_memremap() with the ability to strictly enforce the
      mapping type.

      drm/i915: fix stolen bios_reserved checks

      I started digging this when I noticed that the BDW code was just
      reserving 1mb by coincidence since it was reading reserved fields.
      Then I noticed we didn't have any values set for SNB and earlier, and
      that the HSW sizes were wrong. After that, I noticed that the reserved
      area has a specific start, and may not exactly end where the stolen
      memory ends. I also noticed the base pointer can be zero. So I decided
      to just write a single patch fixing everything instead of 20 patches
      that would be much harder to review.

      This patch may solve random stolen memory corruption/problems on
      almost all platforms. Notice that since this is always dealing with
      the top of the stolen memory, the problems are not so easy to
      reproduce - especially since FBC is still disabled by default.

      One of the major differences of this patch is that we now look at both
      the size and base address. By only looking at the size we were
      assuming that the reserved area was always at the very top of
      stolen, which is not always true.

      After we merge the patch series that allows user space to allocate
      stolen memory we'll be able to write IGT tests that maybe catch the
      bugs fixed by this patch.

      v2:
        - s/BIOS reserved/stolen reserved/g (Chris)
        - Don't DRM_ERROR if we can't do anything about it (Chris)
        - Improve debug messages (Chris).
        - Use the gen7 version instead of gen6 on HSW. Tom found some
          documentation problems, so I think with gen7 we're on the safer
          side (Tom).

      - crtc_state -> old_crtc_state

      Connectors are updated atomically now, so the only interaction
      with the encoder is through base.crtc.

      If it's NULL the encoder's not part of any crtc, and if it's
      not NULL then active should be equal to crtc_state->active.

      drm/i915: Convert connector checking to atomic, v3.

      Right now dpms callbacks can still fiddle with the connector state,
      but it can only turn connectors off.

      This is remediated by only checking crtc->state->active when the
      connector is active, and ignore crtc->state->active when the
      connector is off.

      connectors_active is no longer checked, and will be removed later
      in this series together with dpms.

      Another check for !encoder->crtc is performed by check_encoder_state
      too, so it can be removed.

      Changes since v1:
      - Add commit message.
      - rename state to old_state.
      - Move deletion of mst_port check to mst patch.
      Changes since v2:
      - Fix a null pointer dereference on MST now hw readout is fixed.

      Instead of using the out-of-line average calculation, use the new
      DECLARE_EWMA() macro to declare a signal EWMA, and use that.

      This actually *reduces* the code size slightly (on x86-64) while

      average: provide macro to create static EWMA

      Having the EWMA parameters stored in the runtime struct imposes
      memory requirements for the constant values that could just be
      inlined in the code. This particularly makes sense if there are
      a lot of such structs, for example in mac80211 in the station
      table where each station has a number of these in an array, and
      there can be many stations.

      Provide a macro DECLARE_EWMA() that declares the necessary struct
      and inline functions to access it with the parameters hard-coded;
      using this also means the user no longer needs to 'select AVERAGE'
      as it's entirely self-contained.

      In the mac80211 case, on x86-64, this actually slightly *reduces*
      code size, while also saving 80 bytes of runtime memory per sta.

      modsign: Handle signing key in source tree

      Since commit 1329e8cc69 ("modsign: Extract signing cert from
      CONFIG_MODULE_SIG_KEY if needed"), the build system has carefully coped
      with the signing key being specified as a relative path in either the
      source or or the build trees.

      However, the actual signing of modules has not worked if the filename
      is relative to the source tree.

      Fix that by moving the config_filename helper into scripts/Kbuild.include
      so that it can be used from elsewhere, and then using it in the top-level
      Makefile to find the signing key file.

      Kill the intermediate $(MODPUBKEY) and $(MODSECKEY) variables too, while
      we're at it. There's no need for them.

      modsign: Use if_changed rule for extracting cert from module signing key

      We couldn't use if_changed for this before, because it didn't live in
      the kernel/ directory so we couldn't add it to $(targets). It was easier
      just to leave it as it was.

      Now it's in the certs/ directory we can use if_changed, the same as we
      do for the trusted certificate list.

      Aside from making things consistent, this means we don't need to depend
      explicitly on the include/config/module/sig/key.h file. And we also get
      to automatically do the right thing and re-extract the cert if the user
      does odd things like using a relative filename and then playing silly
      buggers with adding/removing that file in both the source and object
      trees. We always favour the one in the object tree if it exists, and
      now we'll correctly re-extract the cert when it changes. Previously we'd
      *only* re-extract the cert if the config option changed, even if the
      actual file we're using did change.

      Provide a kernel API and a sysfs entry which allow a user to specify
      that when a card is PERSTed, it's image will stay the same, allowing
      it to participate in EEH.

      cxl_reset is used to reflash the card. In that case, we cannot safely
      assert that the image will not change. Therefore, disallow cxl_reset

      cxl: Don't remove AFUs/vPHBs in cxl_reset

      If the driver doesn't participate in EEH, the AFUs will be removed
      by cxl_remove, which will be invoked by EEH.

      If the driver does particpate in EEH, the vPHB needs to stick around
      so that the it can particpate.

      In both cases, we shouldn't remove the AFU/vPHB.

      cxl: Refactor AFU init/teardown

      As with an adapter, some aspects of initialisation are done only once
      in the lifetime of an AFU: for example, allocating memory, or setting
      up sysfs/debugfs files.

      However, we may want to be able to do some parts of the initialisation
      multiple times: for example, in error recovery we want to be able to
      tear down and then re-map IO memory and IRQs.

      Therefore, refactor AFU init/teardown as follows.

       - Create two new functions: 'cxl_configure_afu', and its pair
         'cxl_deconfigure_afu'. As with the adapter functions,
         these (de)configure resources that do not need to last the entire
         lifetime of the AFU.

       - Allocating and releasing memory remain the task of 'cxl_alloc_afu'
         and 'cxl_release_afu'.

       - Once-only functions that do not involve allocating/releasing memory
         stay in the overarching 'cxl_init_afu'/'cxl_remove_afu' pair.
         However, the task of picking an AFU mode and activating it has been
         broken out.

      cxl: Refactor adaptor init/teardown

      Some aspects of initialisation are done only once in the lifetime of
      an adapter: for example, allocating memory for the adapter,
      allocating the adapter number, or setting up sysfs/debugfs files.

      However, we may want to be able to do some parts of the
      initialisation multiple times: for example, in error recovery we
      want to be able to tear down and then re-map IO memory and IRQs.

       - Keep the overarching functions 'cxl_init_adapter' and its pair,
         'cxl_remove_adapter'.

       - Move all 'once only' allocation/freeing steps to the existing
         'cxl_alloc_adapter' function, and its pair 'cxl_release_adapter'
         (This involves moving allocation of the adapter number out of
         cxl_init_adapter.)

       - Create two new functions: 'cxl_configure_adapter', and its pair
         'cxl_deconfigure_adapter'. These two functions 'wire up' the
         hardware --- they (de)configure resources that do not need to
         last the entire lifetime of the adapter

      - MMIO pointer unmapping is guarded by a null pointer check.
         However, iounmap doesn't null the pointer, just invalidate it.
         Therefore, explicitly null the pointer after unmapping.

       - afu_desc_mmio also needs to be unmapped.

       - PCI regions are allocated in cxl_map_adapter_regs.

      cxl: Allocate and release the SPA with the AFU

      Previously the SPA was allocated and freed upon entering and leaving
      AFU-directed mode. This causes some issues for error recovery - contexts
      hold a pointer inside the SPA, and they may persist after the AFU has
      been detached.

      We would ideally like to allocate the SPA when the AFU is allocated, and
      release it until the AFU is released. However, we don't know how big the
      SPA needs to be until we read the AFU descriptor.

      Therefore, restructure the code:

       - Allocate the SPA only once, on the first attach.

       - Release the SPA only when the entire AFU is being released (not
         detached). Guard the release with a NULL check, so we don't free
         if it was never allocated (e.g. dedicated mode)

      cxl: Drop commands if the PCI channel is not in normal state

      If the PCI channel has gone down, don't attempt to poke the hardware.

      We need to guard every time cxl_whatever_(read|write) is called. This
      is because a call to those functions will dereference an offset into an
      mmio register, and the mmio mappings get invalidated in the EEH
      teardown.

      Check in the read/write functions in the header.
      We give them the same semantics as usual PCI operations:
       - a write to a channel that is down is ignored.
       - a read from a channel that is down returns all fs.

      Also, we try to access the MMIO space of a vPHB device as part of the
      PCI disable path. Because that's a read that bypasses most of our usual
      checks, we handle it explicitly.

      As far as user visible warnings go:
       - Check link state in file ops, return -EIO if down.
       - Be reasonably quiet if there's an error in a teardown path,
         or when we already know the hardware is going down.
       - Throw a big WARN if someone tries to start a CXL operation
         while the card is down. This gives a useful stacktrace for
         debugging whatever is doing that.

      powerpc/eeh: Probe after unbalanced kref check

      In the complete hotplug case, EEH PEs are supposed to be released
      and set to NULL. Normally, this is done by eeh_remove_device(),
      which is called from pcibios_release_device().

      However, if something is holding a kref to the device, it will not
      be released, and the PE will remain. eeh_add_device_late() has
      a check for this which will explictly destroy the PE in this case.

      This check in eeh_add_device_late() occurs after a call to
      eeh_ops->probe(). On PowerNV, probe is a pointer to pnv_eeh_probe(),
      which will exit without probing if there is an existing PE.

      This means that on PowerNV, devices with outstanding krefs will not
      be rediscovered by EEH correctly after a complete hotplug. This is
      affecting CXL (CAPI) devices in the field.

      Put the probe after the kref check so that the PE is destroyed
      and affected devices are correctly rediscovered by EEH.

      Merge branch 'vrf-lite'

      David Ahern says:

      ====================
      VRF-lite - v6

      In the context of internet scale routing a requirement that always comes
      up is the need to partition the available routing tables into disjoint
      routing planes. A specific use case is the multi-tenancy problem where
      each tenant has their own unique routing tables and in the very least
      need different default gateways.

      This patch allows the ability to create virtual router domains (aka VRFs
      (VRF-lite to be specific) in the linux packet forwarding stack. The main
      observation is that through the use of rules and socket binding to 
interfaces,
      all the facilities that we need are already present in the 
infrastructure. What
      is missing is a handle that identifies a routing domain and can be used to
      gather applicable rules/tables and uniqify neighbor selection. The scheme 
used
      needs to preserves the notions of ECMP, and general routing principles.

      This driver is a cross between functionality that the IPVLAN driver
      and the Team drivers provide where a device is created and packets
      into/out of the routing domain are shuttled through this device. The
      device is then used as a handle to identify the applicable rules. The
      VRF device is thus the layer3 equivalent of a vlan device.

      The very important point to note is that this is only a Layer3 concept
      so L2 tools (e.g., LLDP) do not need to be run in each VRF, processes can
      run in unaware mode or select a VRF to be talking through. Also the
      behavioral model is a generalized application of the familiar VRF-Lite
      model with some performance paths that need optimization. (Specifically
      the output route selector that Roopa, Robert, Thomas and EricB are
      currently discussing on the MPLS thread)

      High Level points
      =================
      1. Simple overlay driver (minimal changes to current stack)
         * uses the existing fib tables and fib rules infrastructure
      2. Modelled closely after the ipvlan driver
      3. Uses current API and infrastructure.
         * Applications can use SO_BINDTODEVICE or cmsg device indentifiers
           to pick VRF (ping, traceroute just work)
         * Standard IP Rules work, and since they are aggregated against the
           device, scale is manageable
      4. Completely orthogonal to Namespaces and only provides separation in
         the routing plane (and ARP)

      Given the topology above, the setup needed to get the basic VRF
      functions working would be

      Create the VRF devices and associate with a table
          ip link add vrf1 type vrf table 5
          ip link add vrf2 type vrf table 6

      Install the lookup rules that map table to VRF domain
          ip rule add pref 200 oif vrf1 lookup 5
          ip rule add pref 200 iif vrf1 lookup 5
          ip rule add pref 200 oif vrf2 lookup 6
          ip rule add pref 200 iif vrf2 lookup 6

          ip link set vrf1 up
          ip link set vrf2 up

      Enslave the routing member interfaces
          ip link set swp1 master vrf1
          ip link set swp2 master vrf1
          ip link set swp3 master vrf2
          ip link set swp4 master vrf2

      Connected and local routes are automatically moved from main and local
      tables to the VRF table.

      ping using VRF0 is simply
          ping -I vrf0 10.0.1.2

      Design Highlights
      =================
      If a device is enslaved to a VRF device (ie., associated with a VRF)
      then:
      1. Rx path
         The master device index is used as the iif for all lookups.

      2. Tx path
         Similarly, for Tx the VRF device oif is used in the flow to direct
         lookups to the table associated with the VRF via its rule. From there
         the FLOWI_FLAG_VRFSRC flag is used to indicate that the oif should
         not be used for FIB table lookups.

      3. Connected and local routes
         On link up for a device, connected and local routes are added to the
         table associated with the VRF device, rather than the local and main
         tables.

      4. Socket lookups
         Sockets operating in the VRF must be bound to the VRF device. As such
         socket lookups compare the VRF device index to sk_bound_dev_if.

      5. Neighbor entries
         Neighbor entries are not impacted by the VRF device. Entries are
         associated with a particular interface; the VRF association is indirect
         via the interface-to-VRF device enslavement.

      Version 6
      - addressed comments from DaveM

      - added patch to properly set oif in ip_send_unicast_reply. Needs to be
        set to VRF device for proper FIB lookup

      - added patch to handle IP fragments

      Version 5
      - dropped patch regarding socket lookups; no longer needed
        + removed vrf helpers no longer needed after this patch is dropped
      - removed dev_open and close operations
        + no need to reset vrf data on an ifdown and creates problems if a
          slave is deleted while the vrf interface is down (Thanks, Nikolay)
      - cleanups for sparse warnings
        + make C=2 is now clean for vrf driver

      Version 4
      - builds are clean with and without VRF device enabled (no, yes and 
module)
      - tightened the driver implementation
        + device add/delete, slave add/remove, and module unload are all clean
      - fixed RCU references
        + with RCU and lock debugging enabled changes are clean through the
          suite of tests
      - TX path uses custom dst, so patch refactoring rtable allocation is
        dropped along with the patch adding rt_nexthop helper
      - dropped the task patch that adds default bind to interface for sockets
        and the associated chvrf example command
        + the patches are a convenience for running unmodified code. They
          are not needed for the core functionality. Any application with
          support for SO_BINDTODEVICE works properly with this patch set.

      Version 3
      - addressed comments from first 2 RFCs with the exception of the name
        Nicolas: We will do the name conversion once we agree on what the
                 correct name should be (vrf, mrf or something else)

      -  packets flow through the VRF device in both directions allowing the
         following:
         - tcpdump -i vrf<n>
         - tc rules on vrf device
         - netfilter rules on vrf device

      TO-DO
      =====
      1. IPv6

      2. ipsec, xfrms
         - dst patch accepted into ipsec-next; will post VRF patch once merge 
happens

      3. listen filter to allow 1 socket to work with multiple VRF devices
         - i.e., bind to VRF's a, b, c only or NOT VRFs e, f, g

      Eric B:
        I have ipsec working with VRFs implemented using the VRF driver,
        including the worst case scenario of complete duplication in the
        networking config.

      driver into shape, and bug-Fixes and ideas from Hannes, Roopa Prabhu,

      net: Introduce VRF device driver

      This driver borrows heavily from IPvlan and teaming drivers.

      Routing domains (VRF-lite) are created by instantiating a VRF master
      device with an associated table and enslaving all routed interfaces that
      participate in the domain. As part of the enslavement, all connected
      routes for the enslaved devices are moved to the table associated with
      the VRF device. Outgoing sockets must bind to the VRF device to function.

      Standard FIB rules bind the VRF device to tables and regular fib rule
      processing is followed. Routed traffic through the box, is forwarded by
      using the VRF device as the IIF and following the IIF rule to a table
      that is mated with the VRF.

      Example:

         Create vrf 1:
           ip link add vrf1 type vrf table 5
           ip rule add iif vrf1 table 5
           ip rule add oif vrf1 table 5
           ip route add table 5 prohibit default
           ip link set vrf1 up

         Add interface to vrf 1:
           ip link set eth1 master vrf1

      net: Use passed in table for nexthop lookups

      If a user passes in a table for new routes use that table for nexthop
      lookups. Specifically, this solves the case where a connected route does
      not exist in the main table, but only another table and then a subsequent
      route is added with a next hop using the connected route. ie.,

      $ ip route ls
      default via 10.0.2.2 dev eth0
      10.0.2.0/24 dev eth0  proto kernel  scope link  src 10.0.2.15
      169.254.0.0/16 dev eth0  scope link  metric 1003
      192.168.56.0/24 dev eth1  proto kernel  scope link  src 192.168.56.51

      $ ip route ls table 10
      1.1.1.0/24 dev eth2  scope link

      Without this patch adding a nexthop route fails:

      $ ip route add table 10 2.2.2.0/24 via 1.1.1.10
      RTNETLINK answers: Network is unreachable

      With this patch the route is added successfully.

      ====================
      net: dsa: mv88e6xxx: add hardware VLAN support

      This patchset brings support to access hardware VLAN entries in DSA and
      mv88e6xxx, through switchdev VLAN objects.

      In the following example, ports swp[0-2] belong to bridge br0, and ports
      swp[3-4] belong to bridge br1. Here's an example of what can be achieved
      after this patchset:

          # bridge vlan add dev swp1 vid 100 master
          # bridge vlan add dev swp2 vid 100 master
          # bridge vlan add dev swp3 vid 100 master
          # bridge vlan add dev swp4 vid 100 master
          # bridge vlan del dev swp1 vid 100 master

      The above commands correctly programmed hardware VLAN 100 for port swp2,
      while ports swp3 and swp4 use software VLAN 100, as shown with:

          # bridge vlan
          port  vlan ids
          swp0  None
          swp0
          swp1  None
          swp1
          swp2   100

          swp2   100

          swp3   100

          swp3
          swp4   100

          swp4
          br0   None
          br1   None

      Assuming that port 5 is the CPU port, the hardware VLAN table would
      contain the following data:

          VID  FID  SID  0  1  2  3  4  5  6
          100    8    0  x  x  t  x  x  t  x

      Where 'x' means excluded, and 't' means tagged.

      Also, adding an FDB entry to VLAN 100 for port swp2 like this:

          # bridge fdb add 3c:97:0e:11:6e:30 dev swp2 vlan 100

      Would result in the following example output:

          # bridge fdb
          # 01:00:5e:00:00:01 dev eth0 self permanent
          # 01:00:5e:00:00:01 dev eth1 self permanent
          # 00:50:d2:10:78:15 dev swp0 master br0 permanent
          # 00:50:d2:10:78:15 dev swp2 vlan 100 master br0 permanent
          # 3c:97:0e:11:6e:30 dev swp2 vlan 100 self static
          # 00:50:d2:10:78:15 dev swp3 master br1 permanent
          # 00:50:d2:10:78:15 dev swp3 vlan 100 master br1 permanent

      And the Address Translation Unit would contain:

          DB   T/P  Vec State Addr
          008  Port 004   e   3c:97:0e:11:6e:30

      usb: chipidea: define stream mode disable for both roles

      The system bus and chipidea IP have different limitations for
      both host and device mode.
      For example, with below errata, we need to enable SDIS(Stream Disable
      Mode) at host mode. But we don't want it for device mode at the
      same system.

      TAR 9000378958
      Title: Non-Double Word Aligned Buffer Address Sometimes Causes Host to
      Hang on OUT Retry
      Impacted Configuration: Host mode, all transfer types
      Description:
      The host core operating in streaming mode may under run while sending
      the data packet of an OUT transaction. This under run can occur if
      there are unexpected system delays in fetching the remaining packet
      data from memory. The host forces a bad CRC on the packet, the device
      detects the error and discards the packet. The host then retries a Bulk,
      Interrupt, or Control transfer if an under run occurs according to the
      USB specification. During simulations, it was found that the host does
      not issue the retry of the failed bulk OUT. It does not issue any other
      transactions except SOF packets that have incorrect frame numbers.

      The second failure mode occurs if the under run occurs on an ISO OUT
      transaction and the next ISO transaction is a zero byte packet. The host
      does not issue any transactions (including SOFs). The device detects a
      Suspend condition, reverts to full speed, and waits for resume signaling.

      A third failure mode occurs when the host under runs on an ISO OUT and
      the next ISO in the schedule is an ISO OUT with two max packets of 1024
      bytes each. The host should issue MDATA for the first OUT followed by
      DATA1 for the second. However, it drops the MDATA transaction, and
      issues the DATA1 transaction.

      The system impact of this bug is the same regardless of the failure mode
      observed. The host core hangs, the ehci_ctrl state machine waits for the
      protocol engine to send the completion status for the corrupted
      transaction, which never occurs. No indication is sent to the host
      controller driver, no register bits change and no interrupts occur.
      Eventually the requesting application times out.

      Detailed internal behavior:
      The EHCI control state machine (ehci_ctrl) in the DMA block is responsible
      for parsing the schedules and initiating all transactions. The ehci_ctrl
      state machine passes the transaction details to the protocol block by
      writing the transaction information in to the TxFIFO. It then asserts
      the pe_hst_run_pkt signal to inform the host protocol state machine
      (pe_hst_state) that there is a packet in the TxFIFO.
      A tag of 0x0 indicates a start of packet with the data providing the
      following information:

      35:32 Tag
      31:30 Reserved
      29:23 Endpoint (lowest 4 bits)
      22:16 Address
      15:10 Reserved
      9:8 Endpoint speed
      7:6 Endpoint type
      5:6 Data Toggle
      3:0 PID
      The pe_hst_state reads the packet information and constructs the packet
      and issues it to the PHY interface.
      The ehci_ctrl state machine writes the start transaction information in
      to the TxFIFO as 0x03002910c for the OUT packet that had the under run
      error. However, it writes 0xC3002910C for the retry of the Out
      transaction, which is incorrect.
      The pe_hst_state enters a bus timeout state after sending the bad CRC
      for the packet that under ran. It then purges any data that was back
      filled in to the TxFIFO for the packet that under ran. The pe_hst_state
      machine stops purging the TxFIFO when it is empty or if it reads a
      location that has a tag of 0x0, indicating a start of packet command.

      The pe_hst_state reads 0xC3002910C and discards it as it does not decode
      to a start of packet command. It continues to purge the OUT data that
      has been pre-buffered for the OUT retry . The pe_hst_state detects the
      hst_packet_run signal and attempts to read the PID and address
      information from the TxFIFO. This location has packet data and so does
      not decode to a valid PID and so falls through to the PE_HST_SOF_LOAD
      state where the frame_num_counter is updated. The frame_num_counter
      is updated with the data in the TxFIFO. In this case, the data is
      incorrect as the ehci_ctrl state machine did not initiate the load.
      The hst_pe_state machine detects the SOF request signal and sends an
      SOF with the bad frame number. Meanwhile, the ehci_ctrl state machine
      waits indefinitely in the run_pkt state waiting for the completion
      status from pe_hst_state machine, which will never happen.

      The ISO failure case is similar except that there is no retry for ISO.
      The ehci_ctrl state machine moves to the next transfer in the periodic
      schedule. If the under run occurs on the last entry of the periodic
      list then it moves to the Async schedule.

      In the case of ISO OUT simulations, the next ISO is a zero byte OUT
      and again the start of packet command gets corrupted. The TxFIFO is
      empty when the hst_pe_state attempts to read the Address and PID
      information as the transaction is a zero byte packet. This results
      in the hst_pe_state machine staying in the GET_PID state, which means
      that it does not issue any transactions (including SOFs). The device
      detects a Suspend condition and reverts to full speed mode and waits
      for a Resume or Reset signal.

      The EHCI specification allows a Non-DoubleWord (32 bits) offset to
      be used as a current offset for Buffer Pointer Page 0 of the qTD.
      In Non-DoubleWord aligned cases, the core reads the packet data
      from the AHB memory, performs the alignment operation before writing
      it in to the TxFIFO as a 32 bit data word. An End Of Packet tag (EOP)
      is written to the TxFIFO after all the packet data has been written
      in to the TxFIFO. The alignment function is reset to Idle by the EOP
      tag. The corruption of the start of packet command arises because the
      packet buffer for the OUT transaction that under ran is not aligned
      to a DoubleWord, and hence no EOP tag is written to the TxFIFO. The
      alignment function is still active when the start packet information
      is written in to the TxFIFO for the retry of the bulk packet or for
      the next transaction in the case of an under run on an ISO. This
      results in the corruption of the start tag and the transaction
      information.

      Click for waveform showing the command 0x 0000300291 being written in
      to the TX FIFO for the Out that under ran.
      Click for waveform showing the command 0xC3002910C written to the
      TxFIFO instead of 0x 0000300291
      Versions affected: Versions 2.10a and previous versions
      How discovered: Customer simulation

      Workaround:
      1- The EHCI specification allows a non-DoubleWord offset to be used
      as a current offset for Buffer Pointer Page 0 of the qTD. However,
      if a DoubleWord offset is used then this issue does not arise.
      2- Use non streaming mode to eliminate under runs.

      Resolution:
      The fix involves changes to the traffic state machine in the
      vusb_hs_dma_traf block. The ehci_ctrl state machine updates the context
      information by encoding the transaction results on the
      hst_op_context_update signals at the end of a transaction. The signal
      hst_op_context_update is added to the traffic state machine, and the
      tx_fifo_under_ran_r signal is generated if the transaction results in
      an under run error. Click for waveform

      The traffic state machine then traverses to the do_eop states if the
      tx_fifo_under_ran error is asserted. Thus an EOP tag is written in to
      the TxFIFO as shown in this waveform .

      The EOP tag resets the align state machine to the Idle state ensuring
      that the next command written by the echi_ctrl state machine does not
      get corrupted.

      usb: chipidea: introduce ITC tuning interface

      ITC (Interrupt Threshold Control) is used to set the maximum rate at which
      the host/device controller will issue interrupts. The default value is 8 
(1ms)
      for it. EHCI core will modify it to 1, but device mode keeps it as default
      value.

      In some use cases like Android ADB, it only has one usb request for each
      direction, and maximum payload data is only 4KB, so the speed is 4MB/s
      at most, it needs controller to trigger interrupt as fast as possible
      to increase the speed. The USB performance will be better if the interrupt
      can be triggered faster.

      Reduce ITC value is benefit for USB performance, but the interrupt number
      is increased at the same time, it may increase cpu utilization too.
      Most of use case cares about performance, but some may care about
      cpu utilization, so, we leave a platform interface for user.
      We set ITC as 1 (1 micro-frame) as default value which is aligned
      with ehci core default value.

QH/siTD.

      In silicon RTL, this entry only affects QH and siTD, and the hub.addr at
      both QH and siTD are 0 in ehci core for chipidea (with hcd->has_tt = 1).

      So, for QH, if the "usage_tt" flag at RTL is 0, set 
CI_HDRC_SET_NON_ZERO_TTHA
      will not affect QH (with non-hs device); for siTD, set this flag
      will change remaining space requirement for the last transaction from 1023
      bytes to 188 bytes, it can increase the number of transactions within one
      frame, ehci periodic schedule code will not queue the packet if the frame 
space
      is full, so it is safe to set this flag for siTD.

      With this flag, it can fix the problem Alan Stern reported below:
      http://www.spinics.net/lists/linux-usb/msg123125.html
      And may fix Michael Tessier's problem too.

        when destroying hqd. Luckily, this is in gfx7 interface file with 
amdgpu,
        which was used only for bring-up purposes of amdgpu, so no real effect

      rocker: hook ndo_neigh_destroy to cleanup neigh refs in driver

      Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops.  The
      driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is
      no event when the neigh is removed from the device (such as when the 
device
      goes admin down).  This patches hooks ndo_neigh_destroy so the driver can
      know when a neigh is removed from the device.  In response, the driver 
will
      purge the neigh entry from its internal tbl.

      I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if
      this ndo is vestigial or if there are out-of-tree users.  In any case, it
      does what I need here.  An alternative design would be to generate
      NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state 
to
      NUD_NONE so driver knows neigh entry is dead.

      ====================
      Enable smsc911x for use with ACPI

      This set of patches enables the front Ethernet port on the
      ARM Juno development platform when used with an ACPI enabled kernel.

      These patches covert the of_property* calls in the driver to the
      DT/ACPI agnostic device_property* calls, and add the arm hardware
      id to the acpi_match_table.

      To support the above changes I copied a couple routines from
      of_net into the properties.c file, and modified them to
      be ACPI/DT agnostic. I'm not 100% sure this is the correct location
      for these functions. But I think they are required to avoid having
      a dozen different implementations scattered across assorted Ethernet
      adapters that are being enabled to use ACPI properties.

      drivers: net: cpsw: add am335x errata workarround for interrutps

      As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and
      C0_RX_PEND interrupt outputs provide a single transmit interrupt
      that combines transmit channel interrupts TXPEND[7:0] and a
      single receive interrupt that combines receive channel interrupts
      RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are
      connected to the ARM Cortex-A8 interrupt controller (INTC) rather
      than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even
      though CPSW interrupt is cleared by writing appropriate values to
      EOI register the interrupt is not cleared in IRQ controller. So
      interrupt is still pending and CPU is struck in ISR, the
      workaround is to disable the interrupts in ARM irq controller.

      PCI: Rationalize pci_ats_queue_depth() error checking

      We previously returned -ENODEV for devices that don't support ATS (except
      that we always returned 0 for VFs, whether or not they support ATS).

      For consistency, always return -EINVAL (not -ENODEV) if the device doesn't
      support ATS.  Return zero for VFs that support ATS.

      PCI: Embed ATS info directly into struct pci_dev

      The pci_ats struct is small and will get smaller, so I don't think it's
      worth allocating it separately from the pci_dev struct.

      PCI: Allocate ATS struct during enumeration

      Previously, we allocated pci_ats structures when an IOMMU driver called
      pci_enable_ats().  An SR-IOV VF shares the STU setting with its PF, so 
when
      enabling ATS on the VF, we allocated a pci_ats struct for the PF if it
      didn't already have one.  We held the sriov->lock to serialize threads
      concurrently enabling ATS on several VFS so only one would allocate the PF
      pci_ats.

      Gregor reported a deadlock here:

        pci_enable_sriov
          sriov_enable
            virtfn_add
              mutex_lock(dev->sriov->lock)      # acquire sriov->lock
              pci_device_add
                device_add
                  BUS_NOTIFY_ADD_DEVICE notifier chain
                  iommu_bus_notifier
                    amd_iommu_add_device        # iommu_ops.add_device
                      init_iommu_group
                        iommu_group_get_for_dev
                          iommu_group_add_device
                            __iommu_attach_device
                              amd_iommu_attach_device  # iommu_ops.attach_device
                                attach_device
                                  pci_enable_ats
                                    mutex_lock(dev->sriov->lock) # deadlock

      There's no reason to delay allocating the pci_ats struct, and if we
      allocate it for each device at enumeration-time, there's no need for
      locking in pci_enable_ats().

      Allocate pci_ats struct during enumeration, when we initialize other
      capabilities.

      Note that this implementation requires ATS to be enabled on the PF first,
      before on any of the VFs because the PF controls the STU for all the VFs.

      md/raid5: split bio for chunk_aligned_read

      If a read request fits entirely in a chunk, it will be passed directly to 
the
      underlying device (providing it hasn't failed of course).  If it doesn't 
fit,
      the slightly less efficient path that uses the stripe_cache is used.
      Requests that get to the stripe cache are always completely split up as
      necessary.

      So with RAID5, ripping out the merge_bvec_fn doesn't cause it to stop 
work,
      but could cause it to take the less efficient path more often.

      All that is needed to manage this is for 'chunk_aligned_read' do some bio
      splitting, much like the RAID0 code does.

      The split code in blkdev_issue_{discard,write_same} can go away

      For discard, we set max discard sectors to (1<<31)>>9 to ensure

      granularity as long as the granularity is a power of two.

      Removing the call to ->merge_bvec_fn() is also fine, as no driver that

      block: make generic_make_request handle arbitrarily sized bios

      The way the block layer is currently written, it goes to great lengths
      to avoid having to split bios; upper layer code (such as bio_add_page())
      checks what the underlying device can handle and tries to always create
      bios that don't need to be split.

      But this approach becomes unwieldy and eventually breaks down with
      stacked devices and devices with dynamic limits, and it adds a lot of
      complexity. If the block layer could split bios as needed, we could
      eliminate a lot of complexity elsewhere - particularly in stacked
      drivers. Code that creates bios can then create whatever size bios are
      convenient, and more importantly stacked drivers don't have to deal with
      both their own bio size limitations and the limitations of the
      (potentially multiple) devices underneath them.  In the future this will
      let us delete merge_bvec_fn and a bunch of other code.

      We do this by adding calls to blk_queue_split() to the various
      make_request functions that need it - a few can already handle arbitrary
      size bios. Note that we add the call _after_ any call to
      blk_queue_bounce(); this means that blk_queue_split() and
      blk_recalc_rq_segments() don't need to be concerned with bouncing
      affecting segment merging.

      Some make_request_fn() callbacks were simple enough to audit and verify
      they don't need blk_queue_split() calls. The skipped ones are:

       * nfhd_make_request (arch/m68k/emu/nfblock.c)
       * axon_ram_make_request (arch/powerpc/sysdev/axonram.c)
       * simdisk_make_request (arch/xtensa/platforms/iss/simdisk.c)
       * brd_make_request (ramdisk - drivers/block/brd.c)
       * mtip_submit_request (drivers/block/mtip32xx/mtip32xx.c)
       * loop_make_request
       * null_queue_bio
       * bcache's make_request fns

      Some others are almost certainly safe to remove now, but will be left
      for future patches.

      ARM: EXYNOS: switch to using generic cpufreq driver for exynos4x12

      The new CPU clock type allows the use of generic CPUfreq driver.
      Switch Exynos4x12 to using generic cpufreq driver.

      Previously (when exynos-cpufreq driver was used with boost
      functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option
      (which enabled boost functionality) selected EXYNOS_THERMAL
      one. After switching Exynos4x12 platforms to use cpufreq-dt
      driver boost support is enabled in the cpufreq-dt driver
      itself (because there are turbo OPPs defined in the board's
      DTS file). However we still would like to allow enabling
      boost support only if thermal support is also enabled for
      Exynos platforms. To achieve this make ARCH_EXYNOS config
      option select THERMAL and EXYNOS_THERMAL ones.

      Please also note that the switch to use the generic cpufreq-dt
      driver fixes the minor issue present with the old code (support
      for 'boost' mode in the exynos-cpufreq driver was enabled for
      all supported SoCs even though 'boost' frequency was provided
      only for Exynos4x12 ones).

      perf tools: Support static linking with libdw

      The Fedora 22 version of libdw requires a couple of extra libraries to
      link. With a dynamic link the dependencies are pulled in automatically,
      but this doesn't work for static linking. Add the needed libraries
      explicitely to the feature probe and the Makefile.

      v2: Explicitly check for static linking and only add the dependencies
          when -static is set. This is to avoid regressions on Arnaldo's system.

      iommu/tegra-smmu: Parameterize number of TLB lines

      The number of TLB lines was increased from 16 on Tegra30 to 32 on
      Tegra114 and later. Parameterize the value so that the initial default
      can be set accordingly.

      On Tegra30, initializing the value to 32 would effectively disable the
      TLB and hence cause massive latencies for memory accesses translated
      through the SMMU. This is especially noticeable for isochronuous clients
      such as display, whose FIFOs would continuously underrun.

      ARM: tegra: cpuidle: implement cpuidle_state.enter_freeze()

      This callback is expected to do the same as enter() but it has to
      guarantee that interrupts aren't enabled at any point in its execution,
      as the tick is frozen.

      It will be called when the system goes to suspend-to-idle and will
      reduce power usage because CPUs won't be awaken for unnecessary IRQs.

      By setting the CPUIDLE_FLAG_TIMER_STOP flag, we can reuse the same code
      for both the enter() and enter_freeze() callbacks.

      memory: tegra: Add support for a variable-size client ID bitfield

      Recent versions of the Tegra MC hardware extend the size of the client
      ID bitfield in the MC_ERR_STATUS register by one bit.  While one could
      simply extend the bitfield for older hardware, that would allow data
      from reserved bits into the driver code, which is generally a bad idea
      on principle.  So this patch instead passes in the client ID mask from
      from the per-SoC MC data.

      There's no MC support for T210 (yet), but when that support winds up
      in the kernel, the appropriate soc->client_id_mask value for that chip
      will be 0xff.

      Based on an original patch by David Ung <davidu@xxxxxxxxxx>.

      Drivers should not be using __cpuc_* functions nor outer_cache_flush()
      directly.  This change partly cleans up tegra-smmu.c.

      The only difference between cache handling of the tegra variants is
      Denver, which omits the call to outer_cache_flush().  This is due to
      Denver being an ARM64 CPU, and the ARM64 architecture does not provide
      this function.  (This, in itself, is a good reason why these should not
      be used.)

      iommu/tegra-smmu: Fix page table lookup in unmap/iova_to_phys methods

      Fix the page table lookup in the unmap and iova_to_phys methods.
      Neither of these methods should allocate a page table; a missing page
      table should be treated the same as no mapping present.

      More importantly, using as_get_pte() for an IOVA corresponding with a
      non-present page table entry increments the use-count for the page
      table, on the assumption that the caller of as_get_pte() is going to
      setup a mapping.  This is an incorrect assumption.

      Fix both of these bugs by providing a separate helper which only looks
      up the page table, but never allocates it.  This is akin to pte_offset()
      for CPU page tables.

      iommu/tegra-smmu: Fix unmap() method

      The Tegra SMMU unmap path has several problems:
      1. as_pte_put() can perform a write-after-free
      2. tegra_smmu_unmap() can perform cache maintanence on a page we have
         just freed.
      3. when a page table is unmapped, there is no CPU cache maintanence of
         the write clearing the page directory entry, nor is there any
         maintanence of the IOMMU to ensure that it sees the page table has
         gone.

      Fix this by getting rid of as_pte_put(), and instead coding the PTE
      unmap separately from the PDE unmap, placing the PDE unmap after the
      PTE unmap has been completed.

      iommu/tegra-smmu: Fix iova_to_phys() method

      iova_to_phys() has several problems:
      (a) iova_to_phys() is supposed to return 0 if there is no entry present
          for the iova.
      (b) if as_get_pte() fails, we oops the kernel by dereferencing a NULL
          pointer.  Really, we should not even be trying to allocate a page
          table at all, but should only be returning the presence of the 2nd
          level page table.  This will be fixed in a subsequent patch.

      gpio/mxc: mask gpio interrupts in suspend

      Currently in the FSL platform all GPIO interrupts in a bank are muxed
      into two GPIO lines to the GPC interrupt controller. In each GPIO bank
      GPIOs 0-15 are OR'ed into one GPC interrupt controller interrupt and 16-31
      are OR'ed into another. With the current code, if any of the 0-15 or
      16-31 interrupts are marked as wakeup capable, all interrupts belonging
      to that sub-bank (either 0-15 or 16-31) will wake up the device. This is
      because interrupts are only being masked at the interrupt controller
      and not at the GPIO controller.

      This patch allows masking of GPIO interrupts at the GPIO controller during
      suspend if they have not been labeled wakeup capable. This patch uses
      preexisting IRQCHIP_MASK_ON_SUSPEND flag while initializing the GPIO
      interrupts to get the desired behavior.

      pinctrl: atlas7: clear ugly branch statements for pull and drivestrength

      To set/get atlas7 pull & drive strength, we use lots of if/else
      to check pad type. But except mask value or immediate value, all
      actions in these conditional branches are the same.
      So we use predefined pull info table and drive strength table
      to reduce these redundancy code.

      orinoco: Do not call wiphy_unregister() from free_orinocodev()

      alloc_orinocodev() would allocate the wiphy entry, but it would only get
      registered much later in orinoco_init(). If something failed in the init
      process inbetween the call to alloc_orinocodev() and the completion
      of orinoco_init(), the drivers would end up calling wiphy_unregister()
      with a NULL pointer causing beautiful OOPS fireworks.

      Explicitly call wiphy_unregister() instead in the right places.

      rtlwifi: rtl8192c-common: Fix two typos

      In this driver, two variables are masked by one quantity, and then tested
      against a second number with more bits that the mask. Accordingly, the
      test always fails. To minimize the possibility of such typos, a symbolic
      definition of the mask is created and used.

      The separate load and mask operations are also combined into a single
      statement.

      Commit e996db69833a (rtlwifi: rtl8192c: Add init codes for "fw_version"
      and "fw_subversion") added initialization for fw_version, but failed to
      note that the variable in the firmware header is little-endian. The
      following Sparse warning results:

        CHECK   drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
      drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: 
incorrect type in assignment (different base types)

      drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36:    got 
restricted __le16 [usertype] version

      When fixing this problem, I noticed that several of the drivers contain
      nearly identical copies of the firmware header struct, and that only the 
one
      used in rtl8192c{e,u} had correct endian notation. The struct has been
      moved into a common header, and the other drivers will be fixed in
      subsequant patches.

      ASoC: dapm: Consolidate input and output path handling

      After the recent cleanups and generalizations of the DAPM algorithm the
      handling of input and output paths is now fully symmetric. This means by
      making some slight changes to the data structure and using arrays with one
      entry for each direction, rather than separate fields, it is possible to
      create a generic implementation that is capable of handling both input and
      output paths.

      Unfortunately this generalization significantly increases the code size on
      the hot path of is_connected_{input,output}_ep() and
      dapm_widget_invalidate_{input,output}_paths(), which has a negative impact
      on the overall performance. The inner loops of those functions are quite
      small and the generic implementation adds extra pointer arithmetic in a 
few
      places.

      Testing on ARM shows that the combined code size of the specialized
      functions is about 50% larger than the generalized function in relative
      numbers. But in absolute numbers its less than 200 bytes, which is still
      quite small. On the other hand the generalized function increases the
      execution time of dapm_power_one_widget() by 30%. Given that this function
      is one of the most often called functions of the DAPM framework the
      trade-off of getting better performance at expense of generating slightly
      larger code at seems to be worth it.

      To avoid this still keep two versions of these functions around, one for
      input and one for output. But have a generic implementation of the
      algorithm which gets inlined by those two versions. And then let the
      compiler take care of optimizing it and removing he extra instructions.

      This still reduces the source code size as well as the makes making 
changes
      to the implementation more straight forward since the same change does no
      longer need to be done in two separate places. Also on the slow paths we
      can use a generic implementations that handle both input and output paths.

      ath10k: don't remove peer that doesn't exist

      If peer creation failed during offchannel Tx the
      driver attempted to delete the peer nonetheless.
      This caused the ar->num_peers counter to be
      incorrectly decremented. This subsequently could
      cause the counter to drop below 0 and also
      eventually lead to firmware crash because host
      would think there are less peer entries created in

      ath10k: reject 11b tx fragmentation configuration

      Even though there's a WMI enum for fragmentation
      threshold no known firmware actually implements
      it. Moreover it is not possible to rely frame
      fragmentation to mac80211 because firmware clears
      the "more fragments" bit in frame control making
      it impossible for remote devices to reassemble
      frames.

      Hence implement a dummy callback just to say
      fragmentation isn't supported. This effectively
      prevents mac80211 from doing frame fragmentation
      in software.

      This fixes Tx becoming broken after setting
      fragmentation threshold.

      gpio: brcmstb: support wakeup from S5 cold boot

      For wake from S5, we need to:
      - register a reboot handler
      - set wakeup capability before requesting IRQ so wakeup count is
        incremented
      - mask all GPIO IRQs and clear any pending interrupts during driver
        probe to since no driver will yet be registered to handle any IRQs
        carried over from boot at that time, and it's possible that the
        booted kernel does not request the same IRQ anyway.

      This means that /sys/.../power/wakeup_count is valid at boot time, and
      we can properly account for S5 wakeup stats. e.g.:

        ### After waking from S5 from a GPIO key
        # cat /sys/bus/platform/drivers/brcmstb-gpio/f04172c0.gpio/power/wakeup
        enabled
        # cat

      gpio: brcmstb: Add interrupt and wakeup source support

      Uses the gpiolib irqchip helpers.  For this to work, the irq setup
      function is called once per bank instead of once per device.  Note
      that all known uses of this block have a BCM7120 L2 interrupt
      controller as a parent.  Supports interrupts for all GPIOs.

      In the IRQ handler, we check for raised IRQs for invalid GPIOs and
      warn (ratelimited) if they're encountered.

      Also, several drivers (e.g. gpio-keys) allow for GPIOs to be
      configured as wakeup sources, and this GPIO controller supports that
      through a separate interrupt path.

      The de-facto standard DT property "wakeup-source" is checked, since
      that indicates whether the GPIO controller hardware can wake.  Uses
      the IRQCHIP_MASK_ON_SUSPEND irq_chip flag because UPG GIO doesn't have
      any of its own wakeup source configuration.

      Aside regarding gpiolib irqchip helpers: It wasn't obvious (to me)
      that you can have multiple chained irqchips and associated IRQ domains
      for a single parent IRQ, and as long as the xlate function is written
      correctly, a GPIO IRQ request end up checking the correct domain and
      will get associated with the correct IRQ.  What helps make this clear
      is to read
        drivers/gpio/gpiolib-of.c:
         - of_gpiochip_find_and_xlate()
         - of_get_named_gpiod_flags()
        drivers/gpio/gpiolib.c:
         - gpiochip_find()

      Two more veyron-devices - namely Speedy and Minnie and a fix for

      One slightly more interesting fix is the blocking of the last
      16MB of memory on 4GB rk3288 devices. The rk3288 cannot use this
      area for dma operations, so things like the mmc or usb controllers
      regularly fail when trying to read data. This solution mimicks the
      solution from the ChromeOS kernel, who also do not seem to have
      found a better solution yet. Here it only moves to the devicetree.
      As this issue is also present on the arm64 rk3368, any future
      better solution to this problem would need to describe this in
      the devicetree as well and could then remove this block.

      KVM: s390: fix and feature for kvm/next (4.3)

      1. error handling for irq routes
      2. Gracefully handle STP time changes
         s390 supports a protocol for syncing different systems via the stp
         protocol that will steer the TOD clocks to keep all participating
         clocks below the round trip time between the system. In case of
         specific out of sync event Linux can opt-in to accept sync checks.
         This will result in non-monotonic jumps of the TOD clock, which
         Linux will correct via time offsets to keep the wall clock time
         monotonic. Now: KVM guests also base their time on the host TOD,
         so we need to fixup the offset for them as well.

      x86/mce: Reenable CMCI banks when swiching back to interrupt mode

      Zhang Liguang reported the following issue:

      1) System detects a CMCI storm on the current CPU.

      2) Kernel disables the CMCI interrupt on banks owned by the
         current CPU and switches to poll mode

      3) After the CMCI storm subsides, kernel switches back to
         interrupt mode

      4) We expect the system to reenable the CMCI interrupt on banks
         owned by the current CPU

         mce_intel_adjust_timer
         |-> cmci_reenable
             |-> cmci_discover     # owned banks are ignored here

        static void cmci_discover(int banks)
        ...
        for (i = 0; i < banks; i++) {
                ...
                if (test_bit(i, owned)) # ownd banks is ignore here
                        continue;

      So convert cmci_storm_disable_banks() to
      cmci_toggle_interrupt_mode() which controls whether to enable or
      disable CMCI interrupts with its argument.

      NB: We cannot clear the owned bit because the banks won't be
      polled, otherwise. See:

        27f6c573e0f7 ("x86, CMCI: Add proper detection of end of CMCI storms")

      for more info.

      x86/mce: Remove the MCE ring for Action Optional errors

      Use unified genpool to save Action Optional error events and put
      Action Optional error handling in the same notification chain as
      MCE error decoding.

      An MCE is a rare event. Therefore, there's no need to have

      x86/mce: Provide a lockless memory pool to save error records

      printk() is not safe to use in MCE context. Add a lockless
      memory allocator pool to save error records in MCE context.
      Those records will be issued later, in a printk-safe context.
      The idea is inspired by the APEI/GHES driver.

      We're very conservative and allocate only two pages for it but
      since we're going to use those pages throughout the system's
      lifetime, we allocate them statically to avoid early boot time
      allocation woes.

      memory: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also set IRQ_NOPROBE and this has been maintained although it is not
      clear that is really needed. There appears to be a great deal of blind
      copy and paste of this code.

      Merge tag 'perf-core-for-mingo' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      User visible changes:

        - Allow selecting the type of callchains per event, including disabling
          callchains in all but one entry in an event list, to save space, and 
also
          to ask for the callchains collected in one event to be used in other
          events. (Kan Liang)

        - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de 
Melo)
          - A bunch more translate file/pathnames from pointers to strings.
          - Convert numbers to strings for the 'keyctl' syscall 'option' arg.
          - Add missing 'clockid' entries.

        - Fix 'perf probe -L sys_*' as it was not showing all the source code 
for
          syscall functions in the kernel. (Masami Hiramatsu)

        - Make ESC unzoom as well in the hists browser, i.e. in 'report' and 
'top',
          as we're considering repurposing the right and left arrow keys to use 
in
          horizontal scrolling, i.e. leave just ESC to be used for what <- works
          now, and ENTER for what -> does (they are already aliases for ages).
          (Arnaldo Carvalho de Melo)

      Infrastructure fixes:

        - Check for SRCLINE_UNKNOWN case in "srcfile" processing (Andi Kleen)

        - Wrap the slsmg_{printf,write_nstring} slang functions behind 
ui_browser, so
          that we can make the ui_browser based browsers (annotate, menus, 
hists, etc) UI
          library agnostic and usable with multiple backends (slang now, GTK+ 
and others
          in the future, maybe) (Arnaldo Carvalho de Melo)

      jump_label/x86: Work around asm build bug on older/backported GCCs

      Boris reported that gcc version 4.4.4 20100503 (Red Hat
      4.4.4-2) fails to build linux-next kernels that have
      this fresh commit via the locking tree:

        11276d5306b8 ("locking/static_keys: Add a new static_key interface")

      The problem appears to be that even though @key and @branch are
      compile time constants, it doesn't see the following expression
      as an immediate value:

         &((char *)key)[branch]

      More recent GCCs don't appear to have this problem.

      In particular, Red Hat backported the 'asm goto' feature into 4.4,
      'normal' 4.4 compilers will not have this feature and thus not
      run into this asm.

      The workaround is to supply both values to the asm as immediates
      and do the addition in asm.

      net: ipv4: increase dhcp inter device timeout

      When a system has multiple ethernet devices and during DHCP
      request (for using NFS), the system waits only for HZ/2 which is
      500mS before switching to another interface for DHCP.

      There are some routers (Ex: Trendnet routers) which responds to
      DHCP request at about 560mS. When the system has only one
      ethernet interface there is no issue as the timeout is 2S and the
      dev xid doesn't changes and only retries.

      But when the system has multiple Ethernet like DRA74x with CPSW
      in dual EMAC mode, the DHCP response is dropped as the dev xid
      changes while shifting to the next device. So changing inter
      device timeout to HZ (which is 1S).

      bpf: fix build warnings and add function read_trace_pipe()

      There are two improvements in this patch:
       1. Fix the build warnings;
       2. Add function read_trace_pipe() to print the result on
          the screen;

      Before this patch, we can get the result through /sys/kernel/de
      bug/tracing/trace_pipe and get nothing on the screen.
      By applying this patch, the result can be printed on the screen.

      - DMA_NONE which we handle correctly.
      - DMA_BIDIRECTIONAL which is never supposed to be set by SCSI stack.
      - Garbage value.

      Do WARN() and return -EINVAL in the last two cases. virtio_scsi does

      hv_netvsc: Implement set_channels ethtool op

      This enables the use of ethtool --set-channels devname combined N to
      change the number of vRSS queues. Separate rx, tx, and other parameters
      are not supported. The maximum is rsscap.num_recv_que. It passes the
      given value to rndis_filter_device_add through the device_info->num_chn
      field.

      If the procedure fails, it attempts to recover to the prior state. If
      the recovery fails, it logs an error and aborts.

      Current num_chn is saved and restored when changing the MTU.

      dm snapshot: don't invalidate on-disk image on snapshot write overflow

      When the snapshot overflows because of a write to the origin, the on-disk
      image has to be invalidated.  However, when the snapshot overflows because
      of a write to the snapshot, the on-disk image doesn't have to be
      invalidated.  Change the behavior so that the on-disk image is not
      invalidated in this case.

      When the snapshot overflows, the variable snapshot_overflowed is set.
      All writes to the snapshot are disallowed to minimize filesystem
      corruption - this condition is cleared when the snapshot is deactivated
      and activated.

      The user can extend the overflowed snapshot, deactivate and activate it
      again, run fsck (if journaling filesystem is not used) mount it and
      recover the data.

      userns,pidns: Force thread group sharing, not signal handler sharing.

      The code that places signals in signal queues computes the uids, gids,
      and pids at the time the signals are enqueued.  Which means that tasks
      that share signal queues must be in the same pid and user namespaces.

      Sharing signal handlers is fine, but bizarre.

      So make the code in fork and userns_install clearer by only testing
      for what is functionally necessary.

      Also update the comment in unshare about unsharing a user namespace to
      be a little more explicit and make a little more sense.

      unshare: Unsharing a thread does not require unsharing a vm

      In the logic in the initial commit of unshare made creating a new
      thread group for a process, contingent upon creating a new memory
      address space for that process.  That is wrong.  Two separate
      processes in different thread groups can share a memory address space
      and clone allows creation of such proceses.

      This is significant because it was observed that mm_users > 1 does not
      mean that a process is multi-threaded, as reading /proc/PID/maps
      temporarily increments mm_users, which allows other processes to
      (accidentally) interfere with unshare() calls.

      Correct the check in check_unshare_flags() to test for
      !thread_group_empty() for CLONE_THREAD, CLONE_SIGHAND, and CLONE_VM.
      For sighand->count > 1 for CLONE_SIGHAND and CLONE_VM.
      For !current_is_single_threaded instead of mm_users > 1 for CLONE_VM.

      By using the correct checks in unshare this removes the possibility of
      an accidental denial of service attack.

      Additionally using the correct checks in unshare ensures that only an
      explicit unshare(CLONE_VM) can possibly trigger the slow path of
      current_is_single_threaded().  As an explict unshare(CLONE_VM) is
      pointless it is not expected there are many applications that make
      that call.

      Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
      * Poll functions for both event chardev and the buffer one were returning

        stopped the tool working.
      * bmg160 was missing some dependencies in Kconfig
      * berlin2-adc had a misshandled register (wrote a value rather than a 
bitmap)

      * TI opt3001 light sensor
      * TXC PA12 ALS and proximity sensor.
      * mcp3301 ADC support (in mcp320x driver)
      * ST lsm303agr accelerometer and magnetometer drivers (plus some 
st-sensors
        common support to allow different WHOAMI register addresses, devices 
with
        fixed scale and allow interrupt equiped magnetometers).
      * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
      * ADIS16266 gyro (in the adis16260 driver)
      * ADIS16137 gyro (in the adis16136 driver)

      New functionality
      * mmc35240 DT bindings.
      * Inverse unit conversion macros to aid handing of values written to sysfs
        attributes.

      Core cleanup
      * Forward declaration of struct iio_trigger to avoid a compile warning.

      Driver cleanup / fixes
      * mxs-lradc
        - Clarify which parts are supported.
        - Fix spelling erorrs.
        - Missing/extra includes
        - reorder includes
        - add datasheet name listings for all usable channels (to allow them
          to be bound by name from consumer drivers)
      * acpi-als - add some function prefixes as per general iio style.
      * bmc150_magn - replace a magic value with the existing define.
      * vf610 - determine possible sample frequencies taking into account the
        electrical characteristics (defining a minimum sample time)
      * dht11
        - whitespace
        - additional docs
        - avoid mulitple assignments in one line
        - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
          previously used for timing.
      * Fix all drivers that consider 0 a valid IRQ for historical reasons.
      * Export I2C module alias info where previously missing (to allow 
autoprobing)
      * Export OF module alias info where previously missing.
      * mmc35240 - switch some variables into arrays to improve readability.
      * mlx90614 - define some magic numbers for readability.
      * bmc150_magn
        - expand area locked by a mutex to cover all the use of the
          data->buffer.
        - use descriptive naming for a mask instead of a magic value.
      * berin2-adc
        - pass up an error code rather that a generic error
        - constify the iio_chan_spec
        - some other little tidy ups.
      * stk8312
        - fix a dependency on triggered buffers in kconfig
        - add a check for invalid attribute values

          return immediately where relevant
        - rework macro defs to use GENMASK etc
        - change some variable types to reduce unnecessary casting
        - clean up code style
        - drop a local buffer copy for bulk reads and use the one in 
data->buffer
           instead.
      * adis16400 - the adis16448 gyroscope scale was wrong.
      * adis16480 - some more wrong scales for various parts.
      * adis16300 - has an undocumented product id and serial number registers 
so
        use them.
      * iio_simple_dummy - fix some wrong code indentation.
      * bmc150-accel - use the chip ID to detect the chip present rather than
        verifying the expected part was there.  This was in response to a wrong
        ACPI entry on the WinBook TW100.
      * mma8452
        - fix _get_hp_filter_index
        - drop a double include

        - range check input values to attribute writes
        - register defs tidy up using GENMASK and reordering them to be easier

          follow.
        - various coding style cleanups
        - put the Kconfig entry in the write place (alphabetically).

      Tools related
      * Tools cleanup - drop an explicity NULL comparison, some unnecessary 
braces,
        use the ARRAY_SIZE macro, send error messages to stderr instead of 
dropping
        them in the middle of normal output.
      * Fix tools to allow that scale and offset attributes are optional.
      * More tools fixes including allowing true 32bit data (previously an 
overflow
        prevented more than 31bits)

      hwmon: (ltc2978) Add additional chip IDs for LTM4676 and LTM4676A

      Per datasheet, the chip ID for LTM4676 is 0x448x. This was observed
      in real systems. In addition to that, chip ID 0x4401 was observed
      as well. Research shows that the chip ID has been changed from 0x440x
      to 0x448x in datasheet revision C. Add support for the additional chip ID.

      Also add the chip ID for LTM4676A, which is functionally identical
      to LTM4676.

      NFSv4: don't set SETATTR for O_RDONLY|O_EXCL

      It is unusual to combine the open flags O_RDONLY and O_EXCL, but
      it appears that libre-office does just that.

      [pid  3250] stat("/home/USER/.config", {st_mode=S_IFDIR|0700, 
st_size=8192, ...}) = 0
      [pid  3250] 
open("/home/USER/.config/libreoffice/4-suse/user/extensions/buildid", 
O_RDONLY|O_EXCL <unfinished ...>

      NFSv4 takes O_EXCL as a sign that a setattr command should be sent,
      probably to reset the timestamps.

      When it was an O_RDONLY open, the SETATTR command does not
      identify any actual attributes to change.
      If no delegation was provided to the open, the SETATTR uses the
      all-zeros stateid and the request is accepted (at least by the
      Linux NFS server - no harm, no foul).

      If a read-delegation was provided, this is used in the SETATTR
      request, and a Netapp filer will justifiably claim
      NFS4ERR_BAD_STATEID, which the Linux client takes as a sign
      to retry - indefinitely.

      So only treat O_EXCL specially if O_CREAT was also given.

      sunrpc: increase UNX_MAXNODENAME from 32 to __NEW_UTS_LEN bytes

      The current limit of 32 bytes artificially limits the name string that
      we end up stuffing into NFSv4.x client ID blobs. If you have multiple
      hosts with long hostnames that only differ near the end, then this can
      cause NFSv4 client ID collisions.

      Linux nodenames are actually limited to __NEW_UTS_LEN bytes (64), so use
      that as the limit instead. Also, use XDR_QUADLEN to specify the slack
      length, just for clarity and in case someone in the future changes this
      to something not evenly divisible by 4.

      qla2xxx: prevent board_disable from running during EEH

      Commit f3ddac1918fe963bcbf8d407a3a3c0881b47248b ("[SCSI] qla2xxx:
      Disable adapter when we encounter a PCI disconnect.") has introduced a
      code that disables the board, releasing some resources, when reading
      0xffffffff.

      In case this happens when there is an EEH, this read will trigger EEH
      detection and set PCI channel offline. EEH will be able to recover the
      card from this state by doing a reset, so it's a better option than
      simply disabling the card.

      Since eeh_check_failure will mark the channel as offline before
      returning the read value, in case there really was an EEH, we can simply
      check for pci_channel_offline, preventing the board_disable code from
      running if it's true.

      Without this patch, EEH code will try to access those same resources
      that board_disable will try to free. This race can cause EEH recovery to
      fail.

      drm/vmwgfx: Fix crash when unloading vmwgfx v2

      This patch fixes two issues.  One, when a surface is a proxy for a DMA
      buffer, it holds an extra reference that needs to be cleared.

      Two, when fbdev is enabled, we need to unpin the framebuffer before
      unloading the driver.  This is done by a call to vmw_fb_off().

      v2
      Moved unreferencing surface to from vmw_framebuffer_surface_destroy()
      to vmw_kms_new_framebuffer()

      Added "struct vmw_framebuffer *vfb = NULL;" to silence a compiler
      warning.

      Removed error checking after calling vmw_surface/dmabuf_reference()

      drm/vmwgfx: Fixed topology boundary checking for Screen Targets

      For a Screen Target capable display device, the display topology is
      limited by SVGA_REG_MAX_PRIMARY_BOUNDING_BOX_MEM.  Two values are
      checked against this limit:
        1.  Size of the bounding box enclosing all the displays, and
        2.  Size of the total number of displays, e.g. framebuffers

      The limitations above mean we do not have exact max width and
      height for the topology.  The best current option is to set those to
      the maximum texture width/height.

      perf probe: Fix to show lines of sys_ functions correctly

      "perf probe --lines sys_poll" shows only the first line of sys_poll,
      because the SYSCALL_DEFINE macro:

        ----
        SYSCALL_DEFINE*(foo,...)
        {
          body;
        }
        ----

        is expanded as below (on debuginfo)

        ----

        static inline int SYSC_foo(...)
        {
          body;
        }
        int SyS_foo(...) <- is an alias of sys_foo.
        {
          return SYSC_foo(...);
        }
        ----

      So, "perf probe --lines sys_foo" decodes SyS_foo function and it also 
skips
      inlined functions(SYSC_foo) inside the target function because those 
functions
      are usually defined somewhere else.

      To fix this issue, this fix checks whether the inlined function is 
defined at
      the same point of the target function, and if so, it doesn't skip the 
inline
      function.

      sign-file: Document dependency on OpenSSL devel libraries

      The revised sign-file program is no longer a script that wraps the openssl
      program, but now rather a program that makes use of OpenSSL's crypto
      library.  This means that to build the sign-file program, the kernel build
      process now has a dependency on the OpenSSL development packages in
      addition to OpenSSL itself.

      Document this in Kconfig and in module-signing.txt.

      PKCS#7: Appropriately restrict authenticated attributes and content type

      A PKCS#7 or CMS message can have per-signature authenticated attributes
      that are digested as a lump and signed by the authorising key for that
      signature.  If such attributes exist, the content digest isn't itself
      signed, but rather it is included in a special authattr which then
      contributes to the signature.

      Further, we already require the master message content type to be
      pkcs7_signedData - but there's also a separate content type for the data
      itself within the SignedData object and this must be repeated inside the
      authattrs for each signer [RFC2315 9.2, RFC5652 11.1].

      We should really validate the authattrs if they exist or forbid them
      entirely as appropriate.  To this end:

       (1) Alter the PKCS#7 parser to reject any message that has more than one
           signature where at least one signature has authattrs and at least one
           that does not.

       (2) Validate authattrs if they are present and strongly restrict them.
           Only the following authattrs are permitted and all others are
           rejected:

           (a) contentType.  This is checked to be an OID that matches the
                 content type in the SignedData object.

           (b) messageDigest.  This must match the crypto digest of the data.

           (c) signingTime.  If present, we check that this is a valid, 
parseable
                 UTCTime or GeneralTime and that the date it encodes fits within
                 the validity window of the matching X.509 cert.

           (d) S/MIME capabilities.  We don't check the contents.

           (e) Authenticode SP Opus Info.  We don't check the contents.

           (f) Authenticode Statement Type.  We don't check the contents.

           The message is rejected if (a) or (b) are missing.  If the message is
           an Authenticode type, the message is rejected if (e) is missing; if
           not Authenticode, the message is rejected if (d) - (f) are present.

           The S/MIME capabilities authattr (d) unfortunately has to be allowed
           to support kernels already signed by the pesign program.  This only
           affects kexec.  sign-file suppresses them (CMS_NOSMIMECAP).

           The message is also rejected if an authattr is given more than once 
or
           if it contains more than one element in its set of values.

       (3) Add a parameter to pkcs7_verify() to select one of the following
           restrictions and pass in the appropriate option from the callers:

           (*) VERIFYING_MODULE_SIGNATURE

         This requires that the SignedData content type be pkcs7-data and
         forbids authattrs.  sign-file sets CMS_NOATTR.  We could be more
         flexible and permit authattrs optionally, but only permit minimal
         content.

           (*) VERIFYING_FIRMWARE_SIGNATURE

         This requires that the SignedData content type be pkcs7-data and
         requires authattrs.  In future, this will require an attribute
         holding the target firmware name in addition to the minimal set.

           (*) VERIFYING_UNSPECIFIED_SIGNATURE

         This requires that the SignedData content type be pkcs7-data but
         allows either no authattrs or only permits the minimal set.

           (*) VERIFYING_KEXEC_PE_SIGNATURE

         This only supports the Authenticode SPC_INDIRECT_DATA content type
         and requires at least an SpcSpOpusInfo authattr in addition to the
         minimal set.  It also permits an SPC_STATEMENT_TYPE authattr (and
         an S/MIME capabilities authattr because the pesign program doesn't
         remove these).

           (*) VERIFYING_KEY_SIGNATURE
           (*) VERIFYING_KEY_SELF_SIGNATURE

         These are invalid in this context but are included for later use
         when limiting the use of X.509 certs.

       (4) The pkcs7_test key type is given a module parameter to select between
           the above options for testing purposes.  For example:

        echo 1 >/sys/module/pkcs7_test_key/parameters/usage
        keyctl padd pkcs7_test foo @s </tmp/stuff.pkcs7

           will attempt to check the signature on stuff.pkcs7 as if it contains 
a
           firmware blob (1 being VERIFYING_FIRMWARE_SIGNATURE).

timezones

      This is not required for the module signing key, although it doesn't do 
any
      harm â?? it just means that any additional certs in the PEM file are also
      trusted by the kernel.

      But it does allow us to use the extract-cert tool for processing the extra

      hack.

      sign-file: Generate CMS message as signature instead of PKCS#7

      Make sign-file use the OpenSSL CMS routines to generate a message to be
      used as the signature blob instead of the PKCS#7 routines.  This allows us
      to change how the matching X.509 certificate is selected.  With PKCS#7 the
      only option is to match on the serial number and issuer fields of an X.509
      certificate; with CMS, we also have the option of matching by subjectKeyId
      extension.  The new behaviour is selected with the "-k" flag.

      Without the -k flag specified, the output is pretty much identical to the
      PKCS#7 output.

      Whilst we're at it, don't include the S/MIME capability list in the 
message
      as it's irrelevant to us.

      X.509: Change recorded SKID & AKID to not include Subject or Issuer

      The key identifiers fabricated from an X.509 certificate are currently:

       (A) Concatenation of serial number and issuer

       (B) Concatenation of subject and subjectKeyID (SKID)

      When verifying one X.509 certificate with another, the AKID in the target
      can be used to match the authoritative certificate.  The AKID can specify
      the match in one or both of two ways:

       (1) Compare authorityCertSerialNumber and authorityCertIssuer from the 
AKID
           to identifier (A) above.

       (2) Compare keyIdentifier from the AKID plus the issuer from the target
           certificate to identifier (B) above.

      When verifying a PKCS#7 message, the only available comparison is between
      the IssuerAndSerialNumber field and identifier (A) above.

      However, a subsequent patch adds CMS support.  Whilst CMS still supports a
      match on IssuerAndSerialNumber as for PKCS#7, it also supports an
      alternative - which is the SubjectKeyIdentifier field.  This is used to
      match to an X.509 certificate on the SKID alone.  No subject information 
is
      available to be used.

      To this end change the fabrication of (B) above to be from the X.509 SKID
      alone.  The AKID in keyIdentifier form then only matches on that and does
      not include the issuer.

      vgaarb: Stop complaining about absent devices

      Some setups do not register a default VGA device, in which case the VGA
      arbiter will still complain about the (non-existent) PCI device being a
      non-VGA device.

      Fix this by making the error message conditional on a default VGA device
      having been set up. Note that the easy route of erroring out early isn't
      going to work because otherwise priv->target won't be properly updated.

      This causes some limited changes to allow for potential error

      KVM: arm/arm64: vgic: Prevent userspace injection of a mapped interrupt

      Virtual interrupts mapped to a HW interrupt should only be triggered
      from inside the kernel. Otherwise, you could end up confusing the
      kernel (and the GIC's) state machine.

      Rearrange the injection path so that kvm_vgic_inject_irq is
      used for non-mapped interrupts, and kvm_vgic_inject_mapped_irq is
      used for mapped interrupts. The latter should only be called from
      inside the kernel (timer, irqfd).

      KVM: arm/arm64: vgic: Allow HW interrupts to be queued to a guest

      To allow a HW interrupt to be injected into a guest, we lookup the
      guest virtual interrupt in the irq_phys_map list, and if we have
      a match, encode both interrupts in the LR.

      We also mark the interrupt as "active" at the host distributor level.

      On guest EOI on the virtual interrupt, the host interrupt will be
      deactivated.

      - source CPU and HW interrupt can share the same field, as

               5.49%  signal.c
               0.51%  msr.h
          #

          It can be combined with other fields, for instance, experiment with
          '-s srcfile,symbol'.

          There are some oddities in some distros and with some specific DSOs, 
being
          investigated, so your mileage may vary.

        - Update the column width for the "srcline" sort key (Arnaldo Carvalho 
de Melo)

        - Support per-event 'freq' term: (Namhyung Kim)

          $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
          $ perf evlist -F
          cpu/instructions,freq=1234/: sample_freq=1234

      sched: Change the sched_class::set_cpus_allowed() calling context

      Change the calling context of sched_class::set_cpus_allowed() such
      that we can assume the task is inactive.

      This allows us to easily make changes that affect accounting done by
      enqueue/dequeue. This does in fact completely remove
      set_cpus_allowed_rt() and greatly reduces set_cpus_allowed_dl().

      sched: Fix a race between __kthread_bind() and sched_setaffinity()

      Because sched_setscheduler() checks p->flags & PF_NO_SETAFFINITY
      without locks, a caller might observe an old value and race with the
      set_cpus_allowed_ptr() call from __kthread_bind() and effectively undo
      it:

        __kthread_bind()
          do_set_cpus_allowed()
                                                <SYSCALL>
                                                  sched_setaffinity()
                                                    if (p->flags & 
PF_NO_SETAFFINITIY)
                                                    set_cpus_allowed_ptr()
          p->flags |= PF_NO_SETAFFINITY

      Fix the bug by putting everything under the regular scheduler locks.

      This also closes a hole in the serialization of 
task_struct::{nr_,}cpus_allowed.

      sched: Ensure a task has a non-normalized vruntime when returning back to 
CFS

      Current code ensures that a task has a normalized vruntime when switching 
away
      from the fair class, but it does not ensure the task has a non-normalized
      vruntime when switching back to the fair class.

      This is an example breaking this consistency:

        1. a task is in fair class and !queued
        2. changes its class to RT class (still !queued)
        3. changes its class to fair class again (still !queued)

      sched/numa: Fix NUMA_DIRECT topology identification

      Systems which have all nodes at a distance of at most 1 hop should be
      identified as 'NUMA_DIRECT'.

      However, the scheduler incorrectly identifies it as 'NUMA_BACKPLANE'.
      This is because 'n' is assigned to sched_max_numa_distance but the
      code (mis)interprets it to mean 'number of hops'.

      Rik had actually used sched_domains_numa_levels for detecting a
      'NUMA_DIRECT' topology:

        http://marc.info/?l=linux-kernel&m=141279712429834&w=2

      But that was changed when he removed the hops table in the
      subsequent version:

      regulator: core: Reduce rdev locking region when releasing regulator

      When we release a regulator we need to remove references to it from the
      rdev which means locking the rdev.  Currently we also free resources
      associated with the regulator inside the rdev lock but there is no need
      to do this, we can reduce the region the lock is held by restricting it
      to just actions that affect the rdev.

      The qrwlock implementation is slightly heavy in its use of memory

      locking/atomics: Add _{acquire|release|relaxed}() variants of some atomic 
operations

      Whilst porting the generic qrwlock code over to arm64, it became
      apparent that any portable locking code needs finer-grained control of
      the memory-ordering guarantees provided by our atomic routines.

      In particular: xchg, cmpxchg, {add,sub}_return are often used in
      situations where full barrier semantics (currently the only option
      available) are not required. For example, when a reader increments a
      reader count to obtain a lock, checking the old value to see if a writer
      was present, only acquire semantics are strictly needed.

      This patch introduces three new ordering semantics for these operations:

        - *_relaxed: No ordering guarantees. This is similar to what we have
                     already for the non-return atomics (e.g. atomic_add).

        - *_acquire: ACQUIRE semantics, similar to smp_load_acquire.

        - *_release: RELEASE semantics, similar to smp_store_release.

      In memory-ordering speak, this means that the acquire/release semantics
      are RCpc as opposed to RCsc. Consequently a RELEASE followed by an
      ACQUIRE does not imply a full barrier, as already documented in
      memory-barriers.txt.

      Currently, all the new macros are conditionally mapped to the full-mb
      variants, however if the *_relaxed version is provided by the
      architecture, then the acquire/release variants are constructed by
      supplementing the relaxed routine with an explicit barrier.

      locking, compiler.h: Cast away attributes in the WRITE_ONCE() magic

      The kernel build bot showed a new warning triggered by commit:

        76695af20c01 ("locking, arch: use WRITE_ONCE()/READ_ONCE() in 
smp_store_release()/smp_load_acquire()")

      because Sparse does not like WRITE_ONCE() accessing elements
      from the (sparse) RCU address space:

        fs/afs/inode.c:448:9: sparse: incorrect type in initializer (different 
address spaces)
        fs/afs/inode.c:448:9:    expected struct afs_permits *__val
        fs/afs/inode.c:448:9:    got void [noderef] <asn:4>*<noident>

      Solution is to force cast away the sparse attributes for the initializer
      of the union in WRITE_ONCE().

      (And as this now gets too long, also split the macro into multiple lines.)

      perf/ring-buffer: Clarify the use of page::private for high-order AUX 
allocations

      A question [1] was raised about the use of page::private in AUX buffer
      allocations, so let's add a clarification about its intended use.

      The private field and flag are used by perf's rb_alloc_aux() path to
      tell the pmu driver the size of each high-order allocation, so that the
      driver can program those appropriately into its hardware. This only
      matters for PMUs that don't support hardware scatter tables. Otherwise,
      every page in the buffer is just a page.

      This patch adds a comment about the private field to the AUX buffer
      allocation path.

      perf/x86: Fix MSR PMU driver

      Currently we only update the sysfs event files per available MSR, we
      didn't actually disallow creating unlisted events.

      Rework things such that the dectection, sysfs listing and event
      creation are better coordinated.

      Sadly it appears it's impossible to probe R/O MSRs under virt. This
      means we have to do the full model table to avoid listing all MSRs all
      the time.

      mfd: axp20x: Add a cell for the usb power_supply part of the axp20x PMICs

      Add a cell for the usb power_supply part of the axp20x PMICs.

      Note that this cell is only for the usb power_supply part and not the
      ac-power / battery-charger / rtc-backup-bat-charger bits.

      Depending on the board each of those must be enabled / disabled separately
      in devicetree as most boards do not use all 4. So in dt each one needs its
      own child-node of the axp20x node. Another reason for using separate child
      nodes for each is so that other devicetree nodes can have a power-supply
      property with a phandle referencing a node representing a single
      power-supply.

      The decision to use a separate devicetree node for each is reflected on
      the kernel side by each getting its own mfd-cell / platform_device and
      platform-driver.

      Note this commit also makes some whitespace changes to the intialization
      of existing cells in axp20x_cells, these are pure whitespace changes,
      functionally nothing changes.

      clk: track the orphan status of clocks and their children

      While children of orphan clocks are not carried in the orphan-list itself,
      they're nevertheless orphans in their own right as they also don't have an
      input-rate available. To ease tracking if a clock is an orphan or has an
      orphan in its parent path introduce an orphan field into struct clk and
      update it and the fields in child-clocks when a clock gets added or 
removed
      from the orphan-list.

      We can simplify the code by looking for the properties and then if we

      We also change the function name from check_cpu_slb_size() to
      init_mmu_slb_size() as the function doesn't check anything, it only
      initialises mmu_slb_size.

      cxl: sparse: Silence iomem warning in debugfs file creation

      An IO address, tagged with __iomem, is passed to debugfs_create_file
      as private data. This requires that it be cast to void *. The cast
      drops the __iomem annotation and so creates a sparse warning:

        drivers/misc/cxl/debugfs.c:51:57: warning: cast removes address space 
of expression

      The address space marker is added back in the file operations
      (fops_io_u64).

      Silence the warning with __force.

      The Exynos5420 based Peach Pit and Exynos5800 based Peach Pi Chromebooks
      use the Maxim max77802 Power Management IC (PMIC). This PMIC has besides
      other devices, a set of regulators that can be controller over I2C.

      Commit f3caa529c6f5 ("ARM: multi_v7_defconfig: Enable max77802 regulator,
      rtc and clock drivers") was supposed to enable the config option for the
      regulator driver as a module but the final version that landed did not
      include this. The commit was modified and the REGULATOR_MAX77802 removed
      since it was thought to be useless.

      Unfortunately that's not the case for the mentioned reason above so this
      patch enables the needed Kconfig option.

      tracing: Allow triggers to filter for CPU ids and process names

      By extending the filter rules by more generic fields
      we can write triggers filters like

        echo 'stacktrace if cpu == 1' > \
        /sys/kernel/debug/tracing/events/raw_syscalls/sys_enter/trigger

      or

        echo 'stacktrace if comm == sshd'  > \
        /sys/kernel/debug/tracing/events/raw_syscalls/sys_enter/trigger

      CPU and COMM are not part of struct trace_entry. We could add the two
      new fields to ftrace_common_field list and fix up all depending
      sides. But that looks pretty ugly. Another thing I would like to
      avoid that the 'format' file contents changes.

      All this can be avoided by introducing another list which contains
      non field members of struct trace_entry.

      mode.  (In DRA7xx TRM_vE, section 24.9.4.5.2.2.1 PCIe Controller Master

      the master in standby.  Without this some of the clocks do not idle).

      Clear the MSE bit on suspend and enable it on resume.  Clearing MSE bit is

      PCI: Kill off set_irq_flags() usage

      set_irq_flags is ARM-specific with custom flags which have genirq
      equivalents.  Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags.  The translation of flags is as follows:

        IRQF_VALID -> !IRQ_NOREQUEST
        IRQF_PROBE -> !IRQ_NOPROBE
        IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in 
.map()
      functions, and we can simply remove the set_irq_flags calls.  Some users
      also modify IRQ_NOPROBE, and this has been maintained although it is not
      clear that is really needed.  There appears to be a great deal of blind
      copy and paste of this code.

      For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for 
non-bridged
      ports and bridge groups, and the remaining will be later used by VLANs.

      This change is necessary to welcome the support for hardware VLANs (which 
will
      follow soon).

      Changes in v3:

       - reorder commits to improve bisectability and minimize diffs

       - add an ndm_state member in switchdev_fdb_obj instead of an is_static 
boolean

       - drop the need to convert unsigned char *addr to u8 addr[ETH_ALEN]
         (it is casted to char pointer anyway)

      Changes in v2:

       - remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code

       - use ether_addr_copy instead of memcpy for MAC addresses

       - constify MAC address in port_fdb_{add,del}

       - split the mv88e6xxx code refactoring into several patches

      The driver currently manages one FID per port (or bridge group), with a
      mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

      The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
      FID 0 means that multiple address databases are not being used).

      This patch changes the fid_mask for an fid_bitmap of 4096 bits.

      >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
      bridge groups (a bridge group gets the FID of its first member). The

      [media] stv0367: Refine i2c error trace to include i2c address

      When using stv0367 demodulator with STi STB platforms,
      we can have easily have four or more stv0367 demods running
      in the system at one time.

      As typically the b2120 reference design ships with a b2004a daughter
      board, which can accept two dvb NIM cards, and each b2100A NIM
      has 2x stv0367 demods and 2x NXPs tuner on it.

      In such circumstances it is useful to print the i2c address
      on error messages to know which one is failing due to I2C issues.

      f2fs: remove inmem radix tree

      Previously, we use radix tree to index all registered page entries for
      atomic file, but now we only use radix tree to see whether current page
      is indexed or not, since the other user of radix tree is gone in commit
      042b7816aaeb ("f2fs: remove unnecessary call to invalidate inmemory 
pages").

      So in this patch, we try to use one more efficient way:
      Introducing a macro ATOMIC_WRITTEN_PAGE, and setting it as page private
      value to indicate page indexing status. By using this way, we can save
      memory and lookup time.

      f2fs: report EINVAL for unalignment direct IO

      We run ltp testcase with f2fs and obtain a TFAIL in diotest4, the result 
in
      detail is as fallow:

      dio04

      <<<test_start>>>
      tag=dio04 stime=1432278894
      cmdline="diotest4"
      contacts=""

      <<<test_output>>>
      diotest4    1  TPASS  :  Negative Offset
      diotest4    2  TPASS  :  removed
      diotest4    3  TFAIL  :  diotest4.c:129: write allows odd count.returns 
1: Success
      diotest4    4  TFAIL  :  diotest4.c:183: Odd count of read and write
      diotest4    5  TPASS  :  Read beyond the file size
      ......

      the result of ext4 with same environment:

      dio04

      <<<test_start>>>
      tag=dio04 stime=1432259643
      cmdline="diotest4"
      contacts=""
      analysis=exit
      <<<test_output>>>
      diotest4    1  TPASS  :  Negative Offset
      diotest4    2  TPASS  :  removed
      diotest4    3  TPASS  :  Odd count of read and write
      diotest4    4  TPASS  :  Read beyond the file size
      ......

      The reason is that when triggering DIO in f2fs, we will return zero value
      in ->direct_IO if writer's buffer offset, file offset and transfer size is
      not alignment to block size of filesystem, resulting in falling back into
      buffered write instead of returning -EINVAL.

      This patch fixes that problem by returning correct error number for above
      case, and removing the judgement condition in check_direct_IO to make sure
      the verification will be enabled for direct reader too.

      Besides, Jaegeuk Kim pointed out that there is expectional cases we should
      always make direct-io falling back into buffered write, such as dio in
      encrypted file.

      cgroup: make cftype->private a unsigned long

      It's pretty unusual to have an int as a private data field and it
      makes it impossible to carray a pointer value through it.  Let's make
      it an unsigned long.  AFAICS, this shouldn't break anything.

patch, but the
      original patch should be audited further for more occurences of this

      spi: orion: On a38x, implement "50MHZ SPI AC timing" Erratum No. 
FE-9144572

      Description:
      On Armada 38x, the device SPI interface supports frequencies of up to
      50 MHz. However, due to this erratum, when the device core clock is
      250 MHz and the SPI interfaces is configured for 50MHz SPI clock and
      CPOL=CPHA=1, there might occur data corruption on reads from the SPI
      device.

      Workaround:
      Work in one of the following configurations:
      1. Set CPOL=CPHA=0 in "SPI Interface Configuration Register".
      2. Set TMISO_SAMPLE value to 0x2 in "SPI Timing Parameters 1 Register"
      before setting the interface.

      [gregory.clement@xxxxxxxxxxxxxxxxxx}: port to v4.2-rc, use
      is_errata_50mhz_ac instead of using a new ARMADA_380_SPI spi type.

      "protocol" but kept backwards compatibility by always listing
      the protocol as present and enabled. This patch further improves

      batman-adv: Avoid u32 overflow during gateway select

      The gateway selection based on fast connections is using a single value
      calculated from the average tq (0-255) and the download bandwidth (in
      100Kibit). The formula for the first step (tq ** 2 * 10000 * bandwidth)
      tends to overflow a u32 with low bandwidth settings like 50 [100KiBit]
      and a tq value of over 92.

      Changing this to a 64 bit unsigned integer allows to support a
      bandwidth_down with up to ~2.8e10 [100KiBit] and a perfect tq of 255. This
      is ~6.6 times higher than the maximum possible value of the gateway
      announcement TVLV.

      This problem only affects the non-default gw_sel_class 1.

      batman-adv: Replace gw_reselect divisor with simple shift

      The gw_factor is divided by BATADV_TQ_LOCAL_WINDOW_SIZE ** 2 * 64. But the
      rest of the calculation has nothing to do with the tq window size and
      therefore the calculation is just (tmp_gw_factor / (64 ** 3)).

      Replace it with a simple shift to avoid a costly 64-bit divide when the
      max_gw_factor is changed from u32 to u64. This type change is necessary
      to avoid an overflow bug.

with pr_warn()

      On built-in kernels this warning will always splat as this is part
      of the module init. Fix that by shifting the PAT requirement check
      out under the code that does the "quasi-probe" for the device. This
      device driver relies on an existing driver to find its own devices,
      it looks for that device driver and its own found devices, then
      uses driver_for_each_device() to try to see if it can probe each of
      those devices as a frambuffer device with ivtvfb_init_card(). We
      tuck the PAT requiremenet check then on the ivtvfb_init_card()
      call making the check at least require an ivtv device present
      before complaining.

      MEDIA_CAMERA_SUPPORT maybe isn't the best name (only "meye" driver seems
      to drive a real camera in a laptop) but it at least doesn't select the
      TUNERs.

      mfd: wm8994: Fix NULL pointer exception on missing pdata

      If we use the dev_get_platdata, pdata can be NULL in DT environments.
      Actually, NULL pointer exception is occurs with error messages like this:

      [    1.226583] Unable to handle kernel NULL pointer dereference at 
virtual address 00000044
      [    1.467910] [<c02f1e38>] (wm8994_irq_init) from [<c02f1bd4>]

(i2c_device_probe+0x11c/0x17c)

      In wm8994-core, we already checked whether platform data is NULL and set 
the
      wm8994->pdata to platform data if platform data is not NULL.
      So, we can use wm8994->pdata instead of platform data.

      mfd: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"

      be built into the module or udev won't have the necessary information
      to auto load the correct module when the device is added.

      mfd: Kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      mfd: arizona: Fixup register table definitions

      The regmap register definitions have been a source of many small fixes
      as issues are discovered.  As such I made a small automated tool to
      check these definitions. This patch fixes the issues (mostly harmless)
      located by that tool, the issues fall into three catagories:

      1) Volatile registers that have a default in the defaults table (default
      has been removed from the table since it is redundant)
      2) Registers that are marked as volatile but unreadable (register has
      been removed from the volatile list since it is obviously not being
      used)
      3) Registers that arn't readable but have an entry in the defaults
      table (again removed since it is redundant)
      4) Readable non-volatile registers that are missing a default, these are
      dangerous as they won't get synced during a cache sync. Fortunately,
      most of them seem to be registers that shouldn't be there (for example
      wm5102 had readable registers for DRC2 and ISRC3 which is doesn't have)

      Hopefully another tool will be produced to check the actual default
      values themselves but that is outside the scope of this patch.

      mfd: Remove MFD_CROS_EC_SPI depends on OF

      The ChromeOS EC SPI transport driver has a dependency on OF because it
      uses some OF helpers from the <linux/of.h> header. But there isn't a
      need for an explicit dependency since the header has stub functions if
      CONFIG_OF is not defined.

      Also, MFD_CROS_EC_SPI already depends on MFD_CROS_EC which in turn has
      a dependency on OF so in practice can't be selected without CONFIG_OF.

      mfd: arizona: Fix race between runtime suspend and IRQs

      The function arizona_irq_thread (the threaded handler for the arizona
      IRQs) calls pm_runtime_get_sync at the start to ensure that the chip is
      active as we handle the IRQ. If the chip is part way through a runtime
      suspend when an IRQ arrives the PM core will wait for the suspend to
      complete, before resuming. However, since commit 4f0216409f7c
      ("mfd: arizona: Add better support for system suspend") the runtime
      suspend function may call disable_irq, if the chip is going to fully
      power off, which will try to wait for any outstanding IRQs to complete.
      This results in deadlock as the IRQ thread is waiting for the PM
      operation to complete and the PM thread is waiting for the IRQ to
      complete.

      To avoid this situation we use disable_irq_nosync, which allows the
      suspending thread to finish the suspend without waiting for the IRQ to
      complete. This is safe because if an IRQ is being processed it can only
      be blocked at the pm_runtime_get_sync at the start of the handler
      otherwise it wouldn't be possible to suspend.

      Starting from Intel Sunrisepoint (Skylake PCH) the iTCO watchdog resources

      previously they were under the LPC device.

      In order to support the iTCO watchdog on newer PCHs we need to create the

using
      platform data.

      mfd: watchdog: iTCO_wdt: Expose watchdog properties using platform data

      Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across
      the SMBus, unlike previous generations of PCH/ICH where it was on the
      LPC bus. Because it's on the SMBus, it doesn't make sense to pass around
      a 'struct lpc_ich_info', and leaking the type of bus into the iTCO
      watchdog driver is kind of backwards anyway.

      This change introduces a new 'struct itco_wdt_platform_data' for use
      inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint
      code, which neatly avoids having to include lpc_ich headers in the i801
      i2c driver.

      This change is overdue because lpc_ich_info has already found its way
      into other TCO watchdog users, notably the intel_pmc_ipc driver where
      the watchdog actually isn't on the LPC bus as far as I can see.

      A simple translation layer is provided for converting from the existing
      'struct lpc_ich_info' inside the lpc_ich mfd driver.

      KVM: x86/vPMU: Fix unnecessary signed extension for AMD PERFCTRn

      According to AMD programmer's manual, AMD PERFCTRn is 64-bit MSR which,
      unlike Intel perf counters, doesn't require signed extension. This
      patch removes the unnecessary conversion in SVM vPMU code when PERFCTRn
      is being updated.

      [media] media: adv7604: reduce support to first (digital) input

      Using adv7611_read_cable_det() for ADV7612 means that full
      support for '.max_port = ADV7604_PAD_HDMI_PORT_B,' isn't available
      due to the need for multiple port reads to determine cable detection,
      and an agreed mechanism for communicating the separate statuses.

      This patch replaces adv7611_read_cable_det() with a functionally
      identical copy, commented appropriately.

      Earlier submissions [leading to commit 8331d30b] also set .cp_csc,
      which is used in a cp_read() call within adv76xx_log_status().

      xfrm6: Fix IPv6 ECN decapsulation

      Using ipv6_get_dsfield on the outer IP header implies that inner and
      outer header are of the the same address family. For interfamily
      tunnels, particularly 646, the code reading the DSCP field obtains the
      wrong values (IHL and the upper four bits of the DSCP field).
      This can cause the code to detect a congestion encoutered state in the
      outer header and enable the corresponding bits in the inner header, too.

      Since the DSCP field is stored in the xfrm mode common buffer
      independently from the IP version of the outer header, it's safe (and
      correct) to take this value from there.

      netfilter: nf_conntrack: push zone object into functions

      This patch replaces the zone id which is pushed down into functions
      with the actual zone object. It's a bigger one-time change, but
      needed for later on extending zones with a direction parameter, and
      thus decoupling this additional information from all call-sites.

      No functional changes in this patch.

      The default zone becomes a global const object, namely nf_ct_zone_dflt
      and will be returned directly in various cases, one being, when there's
      f.e. no zoning support.

          drm/atomic: Only destroy connector states with connection mutex held

      I tried to fix races of atomic commits against connector
      hot-unplugging. The idea is to ensure lifetimes by holding the
      connection_mutex long enough. That works for synchronous commits, but
      not for async ones.

      For async atomic commit we really need to fix up connector lifetimes
      for real. But that's a much bigger task, so just add more duct-tape:
      For cleaning up connector states we currently don't need the connector
      itself. So NULL it out and remove the locking check. Of course that
      check was to protect the entire sequence, but the modeset itself
      should be save since currently DP MST hot-removal does a dpms-off. And
      that should synchronize with any outstanding async atomic commit.

      Or at least that's my hope, this is all a giant mess.

      drm/qxl: Don't take dev->struct_mutex in bo_force_delete

      It really doesn't protect anything which doesn't have other locks
      already. It also doesn't seem to be wired up into the driver unload
      code fwiw, but that's a different issue.

      drm/rockchip: Don't grab dev->struct_mutex for in mmap offset ioctl

      Since David Herrmann's mmap vma manager rework we don't need to grab
      dev->struct_mutex any more to prevent races when looking up the mmap
      offset. Drop it and instead don't forget to use the unref_unlocked
      variant (since the drm core still cares).

      Aside: I stumbled over the mmap handler which directly does a
      dma_mmap_attrs. But totally fails to grab a reference on the
      underlying object and hence looks like it happily just leaks the ptes
      since there's no guarantee the mmap isn't still around when
      gem_free_object is called. Which the kerneldoc of dma_mmap_attrs
      explicitly forbids.

      [media] usbvision: remove power_on_at_open and timed power off

      This causes lots of problems and is *very* slow as well.

      One of the main problems is that this prohibits the use of the control
      framework since subdevs will be unloaded on power off which is not allowed
      as long as they are used by a usb device.

      Apparently the reason for doing this is to turn off a noisy tuner. My 
hardware
      has no problem with that, and I wonder whether the hardware with that 
noisy
      tuner wasn't just functioning improperly as I have never heard of noisy 
tuners.

      Contact me if you have one of those devices and I can take a look whether 
the
      tuner can't be powered off if necessary by letting the tuner subdevice go
      into standby mode. Unloading the tuner module is just evil and is not the
      right approach.

      [media] V4L2: platform: Add Renesas R-Car JPEG codec driver

      Here's the driver for the Renesas R-Car JPEG processing unit.

      The driver is implemented within the V4L2 framework as a memory-to-memory
      device.  It presents two video nodes to userspace, one for the encoding 
part,
      and one for the decoding part.

      It was found that the only working mode for encoding is no markers 
output, so we
      generate markers with software. In the current version of driver we also 
use
      software JPEG header parsing because with hardware parsing performance is 
lower
      than desired.

      >From a userspace point of view the process is typical (S_FMT, REQBUF,
      optionally QUERYBUF, QBUF, STREAMON, DQBUF) for both the source and 
destination
      queues. STREAMON can return -EINVAL in case of mismatch of output and 
capture
      queues format. Also during decoding driver can return buffers if queued
      buffer with JPEG image contains image with inappropriate subsampling (e.g.
      4:2:0 in JPEG and 4:2:2 in capture).  If JPEG image and queue format 
dimensions
      differ driver will return buffer on QBUF with VB2_BUF_STATE_ERROR flag.

      During encoding the available formats are: V4L2_PIX_FMT_NV12M,
      V4L2_PIX_FMT_NV12, V4L2_PIX_FMT_NV16, V4L2_PIX_FMT_NV16M for source and
      V4L2_PIX_FMT_JPEG for destination.

      During decoding the available formats are: V4L2_PIX_FMT_JPEG for source 
and
      V4L2_PIX_FMT_NV12M, V4L2_PIX_FMT_NV16M, V4L2_PIX_FMT_NV12, 
V4L2_PIX_FMT_NV16
      for destination.

      Performance of current version:
      1280x800 NV12 image encoding/decoding
        decoding ~122 FPS
        encoding ~191 FPS

      [media] v4l2-mem2mem: drop lock in v4l2_m2m_fop_mmap

      [media] s5p-jpeg: Eliminate double kfree()

      video_unregister_device() calls device_unregister(), which calls
      put_device(), which calls kobject_put(), and if this is the last reference
      then kobject_release() is called, which calls kobject_cleanup(), which
      calls ktype's release method which happens to be device_release() in this
      case, which calls dev->release(), which happens to be
      v4l2_device_release() in this case, which calls vdev->release(), which
      happens to be video_device_release(). But video_device_release() is
      called explicitly both in error recovery path of s5p_jpeg_probe() and
      in s5p_jpeg_remove(). The pointers in question are not nullified between
      the two calls, so this is harmful.

      This patch fixes the driver so that video_device_release() is not called
      twice for the same object.

      ideapad-laptop: add alternative representation for Yoga 2 to DMI table

      There is at least one (mine) Yoga 2 Pro in existence that has incorrect
      product version stored in DMI (reading as "INVALID"), causing it to not be
      recognized as Yoga 2 by ideapad-laptop module, which in turn causes
      non-existent hardware rfkills to be always reported as blocked.

      This change adds a second check by board name, which is "Yoga2".
      Looks like it also happens to be "INVALID" on some other Yoga 2 machines
      where product version is correct instead, so the original check is left
      intact to catch both cases.

      asus-laptop: Add key found on Asus F3M

      Asus F3M has two keys labeled with an icon of a touchpad. The first,
      reported as 0x6B is next to the power key and the second, reported as
      0x6A, is F9 combined with Fn button. When I was pressing the latter, I was
      getting "Unknown key 6a pressed" message before applying this patch.

      Asus F3M does not support WMI so the commit does not update key mappings
      in the asus-nb-wmi.c file.

      I have not tested this mapping on any other Asus laptop.

      cleanup IORESOURCE_CACHEABLE vs ioremap()

      Quoting Arnd:
          I was thinking the opposite approach and basically removing all uses
          of IORESOURCE_CACHEABLE from the kernel. There are only a handful of
          them.and we can probably replace them all with hardcoded
          ioremap_cached() calls in the cases they are actually useful.

      All existing usages of IORESOURCE_CACHEABLE call ioremap() instead of
      ioremap_nocache() if the resource is cacheable, however ioremap() is
      uncached by default. Clearly none of the existing usages care about the
      cacheability. Particularly devm_ioremap_resource() never worked as
      advertised since it always fell back to plain ioremap().

      Clean this up as the new direction we want is to convert
      ioremap_<type>() usages to memremap(..., flags).

      mm: enhance region_is_ram() to region_intersects()

      region_is_ram() is used to prevent the establishment of aliased mappings
      to physical "System RAM" with incompatible cache settings.  However, it
      uses "-1" to indicate both "unknown" memory ranges (ranges not described
      by platform firmware) and "mixed" ranges (where the parameters describe
      a range that partially overlaps "System RAM").

      Fix this up by explicitly tracking the "unknown" vs "mixed" resource
      cases and returning REGION_INTERSECTS, REGION_MIXED, or REGION_DISJOINT.
      This re-write also adds support for detecting when the requested region
      completely eclipses all of a resource.  Note, the implementation treats
      overlaps between "unknown" and the requested memory type as
      REGION_INTERSECTS.

      Finally, other memory types can be passed in by name, for now the only
      usage "System RAM".

      HID: wacom: Simplify 'wacom_pl_irq'

      Unlike other IRQ functions, 'wacom_pl_irq' uses the second element of
      the 'tool' array to store information about its single pen. This makes
      the function more difficult to understand (since it doesn't follow the
      general pattern of other IRQ functions) and prevents the possibility of
      refactoring how pen state is stored.

      This patch rewrites 'wacom_pl_irq' to follow the usual IRQ conventions,
      including storing tool type in 'tool[0]' and implicitly tracking prox
      with the 'id[0]' variable.

      Kernel threads excluded from smack checks

      Adds an ignore case for kernel tasks,
      so that they can access all resources.

      Since kernel worker threads are spawned with
      floor label, they are severely restricted by
      Smack policy. It is not an issue without onlycap,
      as these processes also run with root,
      so CAP_MAC_OVERRIDE kicks in. But with onlycap

      bus per switch, not one for the whole cluster. Allow this to be
      represented in the device tree, by adding an optional mii-bus property
      at the switch level. The old platform_device method of instantiation

      net: add explicit logging and stat for neighbour table overflow

      Add an explicit neighbour table overflow message (ratelimited) and
      statistic to make diagnosing neighbour table overflows tractable in
      the wild.

      Diagnosing a neighbour table overflow can be quite difficult in the wild
      because there is no explicit dmesg logged.  Callers to neighbour code
      seem to use net_dbg_ratelimit when the neighbour call fails which means
      the "base message" is not emitted and the callback suppressed messages
      from the ratelimiting can end-up juxtaposed with unrelated messages.
      Further, a forced garbage collection will increment a stat on each call
      whether it was successful in freeing-up a table entry or not, so that
      statistic is only a hint.  So, add a net_info_ratelimited message and
      explicit statistic to the neighbour code.

      So we shouldn't update the txq->cur_tx until all the update to the

      cur_tx performed in the proper order.

      perf evlist: Be more specific on -F/--freq

      Currently perf evlist -F shows the number as if it's always sampling
      frequency.  But we now support per-event freq/period settings.  So it'd
      better to show more detailed info whether it's freq or period.

        $ perf record -e 'cpu/config=1/,cpu/config=2,period=300000/' sleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.017 MB perf.data ]

        $ perf evlist -F
        cpu/config=1/: sample_freq=4000
        cpu/config=2,period=300000/: sample_period=300000

      perf record: Support per-event freq term

      Now perf can set per-event value of time and (sampling) period.  But I
      guess most users like me just want to set frequency rather than period.
      So add the 'freq' term in the event parser.

      perf report: Add support for srcfile sort key

      In some cases it's useful to characterize samples by file. This is
      useful to get a higher level categorization, for example to map cost to
      subsystems.

      Add a srcfile sort key to perf report. It builds on top of the existing
      srcline support.

      Commiter notes:

      E.g.:

        # perf record -F 10000 usleep 1
        [ perf record: Woken up 1 times to write data ]
        [ perf record: Captured and wrote 0.016 MB perf.data (13 samples) ]
        [root@zoo ~]# perf report -s srcfile --stdio
        # Total Lost Samples: 0
        #
        # Samples: 13  of event 'cycles'
        # Event count (approx.): 869878
        #
        # Overhead  Source File
        # ........  ...........
            60.99%  .
            20.62%  paravirt.h
            14.23%  rmap.c
             4.04%  signal.c
             0.11%  msr.h

        #

      The first line is collecting all the files for which srcfiles couldn't 
somehow
      get resolved to:

        # perf report -s srcfile,dso --stdio
        # Total Lost Samples: 0

      perf hists: Update the column width for the "srcline" sort key

      When we introduce a new sort key, we need to update the
      hists__calc_col_len() function accordingly, otherwise the width
      will be limited to strlen(header).

      We can't update it when obtaining a line value for a column (for
      instance, in sort__srcline_cmp()), because we reset it all when doing a
      resort (see hists__output_recalc_col_len()), so we need to, from what is
      in the hist_entry fields, set each of the column widths.

      svcrdma: Change maximum server payload back to RPCSVC_MAXPAYLOAD

      Both commit 0380a3f375 ("svcrdma: Add a separate "max data segs"
      macro for svcrdma") and commit 7e5be28827bf ("svcrdma: advertise
      the correct max payload") are incorrect. This commit reverts both
      changes, restoring the server's maximum payload size to 1MB.

      Commit 7e5be28827bf based the server's maximum payload on the
      _client's_ RPCRDMA_MAX_DATA_SEGS value. That was wrong.

      Commit 0380a3f375 tried to fix this so that the client maximum
      payload size could be raised without affecting the server, but
      managed to confuse matters more on the server side.

      More importantly, limiting the advertised maximum payload size was
      meant to be a workaround, not the actual fix. We need to revisit

        https://bugzilla.linux-nfs.org/show_bug.cgi?id=270

      A Linux client on a platform with 64KB pages can overrun and crash
      an x86_64 NFS/RDMA server when the r/wsize is 1MB. An x86/64 Linux
      client seems to work fine using 1MB reads and writes when the Linux
      server's maximum payload size is restored to 1MB.

      Currently, when trying to connect to already paired device that just
      rotated its RPA MAC address, old address would be used and connection
      would fail. In order to fix that, kernel must scan and receive
      advertisement with fresh RPA before connecting.

      This patch enables new connection establishment procedure. Instead of just
      sending HCI_OP_LE_CREATE_CONN to controller, "connect" will add device to
      kernel whitelist and start scan. If advertisement is received, it'll be
      compared against whitelist and then trigger connection if it matches.
      That fixes mentioned reconnect issue for  already paired devices. It also
      make whole connection procedure more robust. We can try to connect to
      multiple devices at same time now, even though controller allow only one.

      Bluetooth: timeout handling in new connect procedure

      Currently, when trying to connect to already paired device that just
      rotated its RPA MAC address, old address would be used and connection

      This patch makes sure that when new procedure is in use, and we're stuck
      in scan phase because no advertisement was received and timeout happened,
      or app decided to close socket, scan whitelist gets properly cleaned up.

      Bluetooth: preparation for new connect procedure

      Currently, when trying to connect to already paired device that just
      rotated its RPA MAC address, old address would be used and connection
      would fail. In order to fix that, kernel must scan and receive
      advertisement with fresh RPA before connecting.

      This patch adds some fields to hci_conn_params, in preparation to new
      connect procedure.

      explicit_connect will be used to override any current auto_connect action,
      and connect to device when ad is received.

      HCI_AUTO_CONN_EXPLICIT was added to auto_connect enum. When this value
      will be used, explicit connect is the only action, and params can be
      removed after successful connection.

      HCI_CONN_SCANNING is added to hci_conn flags. When it's set, connect is
      scan phase. It gets cleared when advertisement is received, and
      HCI_OP_LE_CREATE_CONN is sent.

      PCI: pciehp: Handle invalid data when reading from non-existent devices

      It's platform-dependent, but an MMIO read to a non-existent PCI device
      generally returns data with all bits set.  This happens when the host
      bridge or Root Complex times out waiting for a response from the device 
and
      fabricates return data to complete the CPU's read.

      One example, reported in the bugzilla below, involved this hierarchy:

        pci 0000:00:1c.0: PCI bridge to [bus 02-3a] Root Port
        pci 0000:02:00.0: PCI bridge to [bus 03-0a] Upstream Port
        pci 0000:03:03.0: PCI bridge to [bus 05-07] Downstream Port
        pci 0000:05:00.0: PCI bridge to [bus 06-07] Thunderbolt Upstream Port
        pci 0000:06:00.0: PCI bridge to [bus 07]    Thunderbolt Downstream Port
        pci 0000:07:00.0: BCM57762 NIC

      Unplugging the Thunderbolt switch and the NIC below it resulted in this:

        pciehp 0000:03:03.0: Surprise Removal
        tg3 0000:07:00.0: tg3_abort_hw timed out, TX_MODE_ENABLE will not clear 
MAC_TX_MODE=ffffffff
        pciehp 0000:06:00.0: unloading service driver pciehp
        pciehp 0000:06:00.0: pcie_isr: intr_loc 11f
        pciehp 0000:06:00.0: Switch interrupt received
        pciehp 0000:06:00.0: Latch open on Slot
        pciehp 0000:06:00.0: Attention button interrupt received
        pciehp 0000:06:00.0: Button pressed on Slot
        pciehp 0000:06:00.0: Presence/Notify input change
        pciehp 0000:06:00.0: Card present on Slot
        pciehp 0000:06:00.0: Power fault interrupt received
        pciehp 0000:06:00.0: Data Link Layer State change
        pciehp 0000:06:00.0: Link Up event

      The pciehp driver correctly noticed that the Thunderbolt switch (05:00.0
      and 06:00.0) and NIC (07:00.0) had been removed, and it called their 
driver
      remove methods.

      Since the NIC was already gone, tg3 received 0xffffffff when it tried to
      read from the device.  The resulting timeout is a tg3 issue and not of
      interest here.

      Similarly, since the 06:00.0 Thunderbolt switch was already gone,
      pcie_isr() received 0xffff when it tried to read PCI_EXP_SLTSTA, and 
pciehp
      thought that was valid status showing that many events had happened: the
      latch had been opened, the attention button had been pressed, a card was
      now present, and the link was now up.  These are all wrong, of course, but
      pciehp went on to try to power up and enumerate devices below the
      non-existent bridge:

        pciehp 0000:06:00.0: PCI slot - powering on due to button press
        pciehp 0000:06:00.0: Surprise Insertion
        pci 0000:07:00.0 id reading try 50 times with interval 20 ms to get 
ffffffff

      bcma: fix access to host_pdev for PCIe devices

      bus->host_pdev is part of a union so bus->host_pdev != NULL is probably
      also true for PCIe devices, because there it accesses bus->host_pci. If
      we access the dev member at the offset defined in struct
      platform_device in struct pci_dev instead we probably get something
      else.

      This patch adds a new function which returns the host dev struct and
      NULL if we do not have a host dev. When this gets registered on MIPS
      brcm47xx we do not have a host dev in some situations.
      This function could also be used in other places.

      This problem was introduced in this commit:

      wlcore: add p2p device support

      When starting a p2p mgmt interface, enable its device role. This
      allows us to keep the sta role disabled and scan on the dev role.

      In general, p2p management interfaces cannot send vif-specific commands
      to FW, as the vif role id is invalid. Only off-channel data and scans
      happen on this vif, so most ops are not relevant.

      If the vif is a p2p mgmt vif, block some mac80211 ops.

      Configure rate policies for p2p mgmt interface, as
      otherwise p2p packets come out with arbitrary rates.

      Since wpa_supplicant currently doesn't support standalone
      p2p device mode (without another attached managed interface),
      add p2p device to the allowed interface combinations without
      decreasing the allowed station count.

      Moreover, increase the station count in some cases, as AP
      mode usually starts as station interface, and the AP interface
      is now different from the p2p management one).

      mac802154: change frame_retries behaviour

      This patch changes the default minimum value of frame_retries to 0 and
      changes the frame_retries default value to 3 which is also 802.15.4
      default.

      We don't use the frame_retries "-1" value as indicator for no-aret mode
      anymore, instead we checking on the ack request bit inside the 802.15.4
      frame control field. This allows a acknowledge handling per frame. This
      checking is done by transceiver or inside xmit callback of driver layer.

      If a transceiver doesn't support ARET handling the transmit

      mac802154: cfg: remove test and set checks

      This patch removes several checks if a value is really changed. This
      makes only sense if we have another layer call e.g. calling the
      driver_ops which is done by callbacks like "set_channel".

      For MAC settings which need to be set by phy registers (if the phy
      supports that handling) this is set by doing an interface up currently
      and are not direct driver_ops calls, so we remove the checks from these
      configuration callbacks.

      mac802154: fix wpan mac setting while lowpan is there

      If we currently change the mac address inside the wpan interface while
      we have a lowpan interface on top of the wpan interface, the mac address
      setting doesn't reach the lowpan interface. The effect would be that the
      IPv6 lowpan interface has the old SLAAC address and isn't working
      anymore because the lowpan interface use in internal mechanism sometimes
      dev->addr which is the old mac address of the wpan interface.

      This patch checks if a wpan interface belongs to lowpan interface, if
      yes then we need to check if the lowpan interface is down and change the
      mac address also at the lowpan interface. When the lowpan interface will
      be set up afterwards, it will use the correct SLAAC address which based
      on the updated mac address setting.

      ieee802154: 6lowpan: remove multiple lowpan per wpan support

      We currently supports multiple lowpan interfaces per wpan interface. I
      never saw any use case into such functionality. We drop this feature now
      because it's much easier do deal with address changes inside the under
      laying wpan interface.

      This patch removes the multiple lowpan interface and adds a lowpan_dev
      netdev pointer into the wpan_dev, if this pointer isn't null the wpan
      interface belongs to the assigned lowpan interface.

      6lowpan: Fix extraction of flow label field

      The lowpan_fetch_skb function is used to fetch the first byte,
      which also increments the data pointer in skb structure,
      making subsequent array lookup of byte 0 actually being byte 1.

      To decompress the first byte of the Flow Label when the TF flag is
      set to 0x01, the second half of the first byte is needed.

      The patch fixes the extraction of the Flow Label field.

      crypto: talitos - Prevent panic in probe error path

      The probe error path for this driver, for all intents and purposes,
      is the talitos_remove() function due to the common "goto err_out".

      Without this patch applied, talitos_remove() will panic under these
      two conditions:

      1. If the RNG device hasn't been registered via
         talitos_register_rng() prior to entry into talitos_remove(),
         then the attempt to unregister the RNG "device" will cause a panic.

      2. If the priv->chan array has not been allocated prior to entry
         into talitos_remove(), then the per-channel FIFO cleanup will panic
         because of the dereference of that NULL "array".

      Both of the above scenarios occur if talitos_probe_irq() fails.

      This patch resolves issue #1 by introducing a boolean to mask the
      hwrng_unregister() call in talitos_unregister_rng() if RNG device
      registration was unsuccessful.

      It resolves issue #2 by checking that priv->chan is not NULL in the
      per-channel FIFO cleanup for loop.

      crypto: caam - Change kmalloc to kzalloc to avoid residual data

      Since fields must be ORed in to operate correctly using any order of
      operations, changed allocations of the combination of extended
      descriptor structs + hardware scatterlists to use kzalloc() instead
      of kmalloc(), so as to ensure that residue data would not be ORed in
      with the correct data.

      We need to unset 'perf_event_attr::freq' bit (default 1) when
      'period' term is specified within event definition like:

        -e 'cpu/cpu-cycles,call-graph=fp,time,period=100000'

      otherwise it will handle the period value as frequency
      (and fail if it crossed the maximum allowed frequency value).

      perf tools: Support full source file paths for srcline

      For perf report/script srcline currently only the base file name of the
      source file is printed. This is a good default because it usually fits
      on the screen.

      But in some cases we want to know the full file name, for example to
      aggregate hits per file.

      In the later case we need more than the base file name to resolve file
      naming collisions: for example the kernel source has ~70 files named
      "core.c"

      It's also useful as input to post processing tools which want to point
      to the right file.

      Add a flag to allow full file name output.

      Add an option to perf report/script to enable this option.

      ALSA: hda - Fix pin config and mapping on Alienware 15

      Alienware 15 has CA0132 codec for its onboard sound, but the pin
      config and mapping seem quite different from other Creative boards.
      This patch corrects them, at least, for providing the right headphone
      and mic jack notification, as well as removing the non-existing SPDIF
      pins.

      Even with this fix, not all stuff works perfectly yet, mainly because
      of the badly written ca0132 driver code -- it has too many implicit
      assumptions of pin configs and maps.  Nevertheless, this is a small
      good step forward.

      The echoaudio locally defines TRUE and FALSE.  Not only is this
      redundant given that C now has a boolean type it results in lots of

      definitions.  Fix this by removing the local defines and converting all

      removing the macros is less safe due to implicit inclusion of the other

      As an extension of aef3156d7, there is no sense in repeatedly calling the
      'wacom_set_report' and 'wacom_get_report' functions if they return an

      either a hard error code was returned or repeated attempts at recovering
      from a "soft" error all failed. In either case, doing even more retries is
      not likely to resolve whatever is wrong.

      ASoC: max98090: Fix sequencing when starting additional routes

      Enforce correct device sequencing when configuring a new
      audio route when there is an existing active audio route(s).

      This patch fixed recording noise issue while playback is active.

      We have some registers which require the device to be in full shutdown
      or to enter full shutdown before the register settings will take effect.
      Currently the driver is not shutting down the device when a new audio
      route is created. If a new audio route is made active while there is
      already an active audio route, then the required register sequencing is
      violated. A hardware shutdown toggle when creating a new audio route
      corrects the sequencing error. The device must remain in hardware
      shutdown for 40ms to allow the internal hardware core to fully shutdown.

      clockevents/drivers/timer-sp804: Migrate to new 'set-state' interface

      Migrate timer-sp driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      There are few more changes worth noticing:

      - The clockevent device was disabled by writing: 'TIMER_CTRL_32BIT |
        TIMER_CTRL_IE' to ctrl register earlier. i.e. by un-setting the
        TIMER_CTRL_ENABLE bit. Its done by writing zero now and should have
        the same effect.

      - For shutdown and resume we were writing the same value twice to the
        register (to disable the timer), which is fixed now.

      - Switching to oneshot mode was divided into two parts earlier:
        - Firstly set_mode() was writing:
          'TIMER_CTRL_32BIT | TIMER_CTRL_IE | TIMER_CTRL_ONESHOT'
          to ctrl register (device not enabled yet)
        - Then sp804_set_next_event() was enabling the device by writing
          'readl(ctrl) | TIMER_CTRL_ENABLE' to the ctrl register. This was
          unnecessarily complicated.
        - Change this to: Stop device on set_state_oneshot and configure it in
          sp804_set_next_event().

      clockevents/drivers/timer-imx-gpt: Migrate to new 'set-state' interface

      Migrate timer-imx-gpt driver to the new 'set-state' interface provided
      by clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      Also drop:
      - 'imx_timer.cem': It was caching the last state of the clockevent
        device. The same behavior can be achieved by using clockevents state
        helpers. These helpers are only required for oneshot mode as
        shutdown/resume wouldn't be done twice by the core.

      - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
        by drivers. The prints are modified to print the set-state functions
        name now to debug the driver.

      clockevents/drivers/dw_apb_timer: Add dynamic irq flag to the timer

      Commit d2348fb6fdc6 ("tick: Dynamically set broadcast irq affinity")
      adds one excellent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the
      interrupt affinity of the broadcast interrupt to the cpu which has the
      earliest expiry time. This patch adds CLOCK_EVT_FEAT_DYNIRQ flag to
      avoid unnecessary wakeups and IPIs when the dw_apb_timer is used as
      broadcast timer.

      A simple test:
      ~ # rm /tmp/test.sh
      ~ # cat > /tmp/test.sh
      cat /proc/interrupts
      for i in `seq 10` ; do sleep $i; done
      cat /proc/interrupts
      ~ # chmod +x /tmp/test.sh
      ~ # taskset 0x2 /tmp/test.sh

      This patch removes 50% wakeups and almost 100% broadcast timer IPIs!

      Migrate time-armada-370-xp driver to the new 'set-state' interface
      provided by clockevents core, the earlier 'set-mode' interface is marked
      obsolete now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

        same.
        same state twice and so perhaps the check wasn't required.
      - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
        by drivers and it was used just to print old-state:new-state. The
        debug prints are called from mxs_irq_clear() now based on the
        state-name passed to it. The printed name will be same for shutdown
        and resume states as they use the same callback pointer.

      clockevents/drivers/sh_cmt: Remove obsolete sh-cmt-32-fast 
platform_device_id entry

      Since commit 59b89af1d5551c12 ("ARM: shmobile: sh7372: Remove Legacy C
      SoC code"), there are no more users left of the "sh-cmt-32-fast"
      platform device name. Hence remove the corresponding platform_device_id
      entry from the driver.

      Since the mailbox core users hrtimers now, it can handle much higher

      mailbox: switch to hrtimer for tx_complete polling

      The mailbox core uses jiffy based timer to handle polling for the
      transmit completion. If the client/protocol have/support notification
      of the last packet transmit completion via ACK packet, then we tick the
      Tx state machine immediately in the callback. However if the client
      doesn't support that mechanism we might end-up waiting for atleast a
      jiffy even though the remote is ready to receive the next request.

      This patch switches the timer used for that polling from jiffy-based
      to hrtimer-based so that we can support polling at much higher time
      resolution.

      HID: wacom: Do not repeatedly attempt to set device mode on error

      As an extension of aef3156d7, there is no sense in repeatedly calling the
      'wacom_set_report' and 'wacom_get_report' functions if they return an
      error. Getting an error from them implies that the device is out to lunch:
      either a hard error code was returned or repeated attempts at recovering
      from a "soft" error all failed. In either case, doing even more retries is
      not likely to resolve whatever is wrong.

      i2c: tegra: update CONFIG_LOAD for new conifiguration

      Once the new configuration is set on the conifg register of
      I2C controller, it is require to update the CONFIG_LOAD register
      to transfer the new SW configuration to actual HW internal
      registers that would be used in the actual logic.

      It is like, SW is programming only shadow registers through
      regular configuration and when these load_config bit fields
      are set to 1, it causes the regular/shadows registers
      configuration transferred to the HW internal active registers.
      So SW has to set these bit fields at the end of all regular
      registers configuration. And these config_load bits are HW
      auto-clear bits. HW clears these bit fields once the register
      configuration is moved to HW internal active registers. So SW
      has to wait until these bits are auto-cleared before going
      for any further programming

      This mechanism is supported on T124 and after this SoCs.

      i2c: xiic: Remove the Addressed as slave interrupt

      Currently there is no slave mode support in the driver
      also in the isr we just ack it and do nothing.

      it has the same i2c address with controller.

      For example,
      On the pxa1928 based platform, where PMIC (88pm860) is present @0x30
      address on TWSI0 interface, and if we set 0x30 as a slave address in
      pxa1928 TWSI0 module, all the transactions towards PMIC would go for toss.

      System ports are unique identifiers in a multi-ASIC environment that

      Since system port to local port mapping is not part of the HW-SW

      mpls: Enforce payload type of traffic sent using explicit NULL

      RFC 4182 s2 states that if an IPv4 Explicit NULL label is the only
      label on the stack, then after popping the resulting packet must be
      treated as a IPv4 packet and forwarded based on the IPv4 header. The
      same is true for IPv6 Explicit NULL with an IPv6 packet following.

      Therefore, when installing the IPv4/IPv6 Explicit NULL label routes,
      add an attribute that specifies the expected payload type for use at
      forwarding time for determining the type of the encapsulated packet
      instead of inspecting the first nibble of the packet.

      The detail of patches is as follow:

      Patch 1/5 add the necessary core perf APIs perf_event_attrs(),
      perf_event_get(),perf_event_read_local() when accessing events
      counters in eBPF programs

      Patch 2/5 rewrites part of the bpf_prog_array map code and make it
      more generic;

      Patch 3/5 introduces a new bpf map type. This map only stores the
      pointer to struct perf_event;

      Patch 4/5 implements function bpf_perf_event_read() that get the
      selected hardware PMU conuter;

      Patch 5/5 gives a simple example.

      perf: add the necessary core perf APIs when accessing events counters in 
eBPF programs

      This patch add three core perf APIs:
       - perf_event_attrs(): export the struct perf_event_attr from struct
         perf_event;
       - perf_event_get(): get the struct perf_event from the given fd;
       - perf_event_read_local(): read the events counters active on the
         current CPU;
      These APIs are needed when accessing events counters in eBPF programs.

      The API perf_event_read_local() comes from Peter and I add the
      corresponding SOB.

      Merge branch 'mv88e6xxx-switchdev-fdb'

      Vivien Didelot says:

      ====================
      net: dsa: mv88e6xxx: support switchdev FDB objects

      This patchset refactors the DSA and mv88e6xxx code to use the switchdev 
FDB
      objects.

      The first two patches add minor but necessary changes to switchdev, the 
third
      one implements the switchdev glue in DSA for FDB routines, and the 
remaining
      ones refactor the FDB access functions in the mv88e6xxx code.

      Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to 
br1):

          # bridge fdb add 3c:97:0e:11:30:6e dev swp2
          # bridge fdb add 3c:97:0e:11:40:78 dev swp3
          # bridge fdb add 3c:97:0e:11:50:86 dev swp4
          # bridge fdb del 3c:97:0e:11:40:78 dev swp3
          # bridge fdb
          01:00:5e:00:00:01 dev eth0 self permanent
          01:00:5e:00:00:01 dev eth1 self permanent
          00:50:d2:10:78:15 dev swp0 master br0 permanent
          3c:97:0e:11:30:6e dev swp2 self static
          00:50:d2:10:78:15 dev swp3 master br1 permanent
          3c:97:0e:11:50:86 dev swp4 self static
          # cat /sys/kernel/debug/dsa0/atu
          # DB   T/P  Vec State Addr
          # 001  Port 004   e   3c:97:0e:11:30:6e
          # 004  Port 010   e   3c:97:0e:11:50:86

      For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for 
non-bridged
      ports and bridge groups, and the remaining will be later used by VLANs.

      This change is necessary to welcome the support for hardware VLANs (which 
will
      follow soon).

      Changes in v2:

       - remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code

       - use ether_addr_copy instead of memcpy for MAC addresses

       - constify MAC address in port_fdb_{add,del}

       - split the mv88e6xxx code refactoring into several patches

      net: dsa: mv88e6xxx: rework FDB getnext operation

      This commit adds a low level _mv88e6xxx_atu_getnext function and helpers
      to rewrite the mv88e6xxx_port_fdb_getnext operation.

      A mv88e6xxx_atu_entry structure is added for convenient access to the
      hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value.

      The previous implementation did not handle the eventual trunk mapping.
      If the related bit is set, then the ATU data register would contain the
      trunk ID, and not the port vector.

      Check this in the FDB getnext operation and do not handle it (yet).

      net: dsa: mv88e6xxx: extend fid mask

      The driver currently manages one FID per port (or bridge group), with a
      mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

      The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
      FID 0 means that multiple address databases are not being used).

      This patch changes the fid_mask for an fid_bitmap of 4096 bits.

      >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
      bridge groups (a bridge group gets the FID of its first member). The
      remaining bits will be reserved for VLAN entries.

      extcon: arizona: Simplify pdata symantics for micd_dbtime

      Currently micd_dbtime can be set to 0 for default, 1 for 4 measurements,
      or a greater than 16-bit value for 2 measurements. This patch simplifies
      the symantics to 2 for 2 measurements, 4 for 4 measurements and any
      other value for the default.

      I am not super keen on changing the symantics of the pdata at this stage
      in the drivers life, but acceptance of the DT binding for this field has
      been made conditional on this happening.

      extcon: arizona: Declare 3-pole jack if we detect open circuit on mic

      Detecting an open-circuit on the microphone pin, usually means the
      headset has a microphone but the cable is faulty. Currently the code
      will simply stop detecting and declare nothing in this situation. It is
      better to declare this as headphones such that the user can still use
      their headset as plain headphones even if the microphone is faulty.

      It uses VR12.0 to report the output voltage. This requires an explicit

      s390/dasd: enhance CUIR scope detection

      This patch adds an enhanced detection for control unit initiated
      reconfiguration request scope.
      The first approach assumed the scope of the reconfiguration request
      to be restricted to the path on which the message was received.
      The enhanced approach determines the full scope of the reconfiguration
      request by evaluating additional path and device selection information
      contained in the reconfiguration message.

      s390/dasd: fix failing path verification

      DASD path verification requires the usage of sleep_on_immediatly to
      ensure that no other I/O request is blocking the recovery of
      disconnected devices. But two concurrent path verification workers for
      the same device may kill each others requests due to the usage of the
      immediate sleep_on function. This may lead to unsuccessful path
      verifications.

      Prevent that two parallel path verification workers conflict with
      each other by implementing a device flag signalling a already running
      worker.

      Btrfs: add support for blkio controllers

      This attaches accounting information to bios as we submit them so the
      new blkio controllers can throttle on btrfs filesystems.

      Not much is required, we're just associating bios with blkcgs during 
clone,
      calling wbc_init_bio()/wbc_account_io() during writepages submission,
      and attaching the bios to the current context during direct IO.

      Finally if we are splitting bios during btrfs_map_bio, this attaches
      accounting information to the split.

      The end result is able to throttle nicely on single disk filesystems.  A
      little more work is required for multi-device filesystems.

      Btrfs: fix parity scrub of RAID 5/6 with missing device

      When testing the previous patch, Zhao Lei reported a similar bug when
      attempting to scrub a degraded RAID 5/6 filesystem with a missing
      device, leading to NULL pointer dereferences from the RAID 5/6 parity
      scrubbing code.

      The first cause was the same as in the previous patch: attempting to
      call bio_add_page() on a missing block device. To fix this,
      scrub_extent_for_parity() can just mark the sectors on the missing
      device as errors instead of attempting to read from it.

      Additionally, the code uses scrub_remap_extent() to map the extent of
      the corresponding data stripe, but the extent wasn't already mapped. If
      scrub_remap_extent() finds a missing block device, it doesn't initialize
      extent_dev, so we're left with a NULL struct btrfs_device. The solution
      is to use btrfs_map_block() directly.

      Btrfs: fix device replace of a missing RAID 5/6 device

      The original implementation of device replace on RAID 5/6 seems to have
      missed support for replacing a missing device. When this is attempted,
      we end up calling bio_add_page() on a bio with a NULL ->bi_bdev, which
      crashes when we try to dereference it. This happens because
      btrfs_map_block() has no choice but to return us the missing device
      because RAID 5/6 don't have any alternate mirrors to read from, and a
      missing device has a NULL bdev.

      The idea implemented here is to handle the missing device case
      separately, which better only happen when we're replacing a missing RAID
      5/6 device. We use the new BTRFS_RBIO_REBUILD_MISSING operation to
      reconstruct the data from parity, check it with
      scrub_recheck_block_checksum(), and write it out with
      scrub_write_block_to_dev_replace().

      Btrfs: add RAID 5/6 BTRFS_RBIO_REBUILD_MISSING operation

      The current RAID 5/6 recovery code isn't quite prepared to handle
      missing devices. In particular, it expects a bio that we previously
      attempted to use in the read path, meaning that it has valid pages
      allocated. However, missing devices have a NULL blkdev, and we can't
      call bio_add_page() on a bio with a NULL blkdev. We could do manual
      manipulation of bio->bi_io_vec, but that's pretty gross. So instead, add
      a separate path that allows us to manually add pages to the rbio.

      Btrfs: count devices correctly in readahead during RAID 5/6 replace

      Commit 5fbc7c59fd22 ("Btrfs: fix unfinished readahead thread for raid5/6
      degraded mounting") fixed a problem where we would skip a missing device
      when we shouldn't have because there are no other mirrors to read from
      in RAID 5/6. After commit 2c8cdd6ee4e7 ("Btrfs, replace: write dirty
      pages into the replace target device"), the fix doesn't work when we're
      doing a missing device replace on RAID 5/6 because the replace device is
      counted as a mirror so we're tricked into thinking we can safely skip
      the missing device. The fix is to count only the real stripes and decide
      based on that.

      Btrfs: remove misleading handling of missing device scrub

      scrub_submit() claims that it can handle a bio with a NULL block device,
      but this is misleading, as calling bio_add_page() on a bio with a NULL

      In addition, I do a small cleanup of the locking helpers, removing a case

      Btrfs: fix defrag to merge tail file extent

      The file layout is

      [extent 1]...[extent n][4k extent][HOLE][extent x]

      extent 1~n and 4k extent can be merged during defrag, and the whole
      defrag bytes is larger than our defrag thresh(256k), 4k extent as a
      tail is left unmerged since we check if its next extent can be merged
      (the next one is a hole, so the check will fail), the layout thus can
      be

      [new extent][4k extent][HOLE][extent x]
       (1~n)

      To fix it, beside looking at the next one, this also looks at the
      previous one by checking @defrag_end, which is set to 0 when we
      decide to stop merging contiguous extents, otherwise, we can merge
      the previous one with our extent.

      Also, this makes btrfs behave consistent with how xfs and ext4 do.

      Btrfs: fix warning in backref walking

      When we do backref walking, we search firstly in queued delayed refs
      and then the on-disk backrefs, but we parse differently for shared
      references, for delayed refs we also add 'ref->root' while for on-disk
      backrefs we don't, this can prevent us from merging refs indexed
      by the same bytenr and cause find_parent_nodes() to throw a warning at
      'WARN_ON(ref->count < 0)', for example, when we have a shared data extent
      with 'ref_cnt=1' and a delayed shared data with a BTRFS_DROP_DELAYED_REF,
      that happens.

      For shared references, no matter if it's delayed or on-disk, ref->root is
      not at all used, instead it's ref->parent that really matters, so this has
      delayed refs handled as the same way as on-disk refs.

      In my test machine, its fail rate is about 30%.
      In another vm(vmware), its fail rate is about 50%.

      Reason:
        btrfs/070 do replace and defrag with fsstress simultaneously,
        after above operation, checksum error is found by scrub.

        Actually, it have no relationship with defrag operation, only
        replace with fsstress can trigger this bug.

        old data from source device by replace code in debug, to avoid
        above problem, we can set target block group to readonly in
        replace period, so new data requested by other operation will
        not write to same place with replace code.

        Before patch(4.1-rc3):
          30% failed in 100 xfstests.
        After patch:
          0% failed in 300 xfstests.

      It also happened in btrfs/071 as it's another scrub with IO load tests.

       place1: if (key.objectid > logic_end) ...
       place2: if (logic_start >= logic_end) ...

       (place2 is typo, is should be ">", it is copied from other

      We can fix above typo directly, but the root reason is ambiguous
      meaning of logic_end in scrub raid56 parity.

      In other place, XXX_end is pointed to data which is not included,
      and we need to process segment of [XXX_start, XXX_end).

      But for scrub raid56 parity, logic_end is pointed to lattest data
      need to process, and introduced many "+ 1" and "- 1" in code as
      below:
       length = sparity->logic_end - sparity->logic_start + 1
       logic_end - logic_start + 1

      operation, like:
        loop() {
          if (parity) {
            scrub_parity_stripe();
            continue;
          }

          check_cancel_and_pause()

          scrub_normal_stripe();
        }

      Reason is when introduce raid56 stripe scrub, new code is inserted
      simplely to front of loop.

      Better to:
        loop() {
          check_cancel_and_pause()

          if (parity)
            scrub_parity_stripe();
          else
            scrub_normal_stripe();
        }

      This patch adjusted code place to realize above sequence.

      btrfs: Show detail information when mount failed on missing devices

      When mount failed because missing device, we can see following
      dmesg:
       [ 1060.267743] BTRFS: too many missing devices, writeable mount is not 
allowed
       [ 1060.273158] BTRFS: open_ctree failed

      This patch add missing_device_number and tolerated_missing_device_number
      to above output, to let user know what really happened, and helps
      bug-report and debug.

      dmesg after patch:

      btrfs: Fix scrub panic when leaf crosses stripes

      Scrub panic in following operation:
        mkfs.ext4 /dev/vdh
        btrfs-convert /dev/vdh
        mount /dev/vdh /mnt/tmp1
        btrfs scrub start -B /dev/vdh
        (panic)

      Reason:
        1: In some case, leaf created by btrfs-convert was splited into 2
           strips.
        2: Scrub bypassed part of above wrong leaf data, but remain data
           caused panic in scrub_checksum_tree_block().

      For reason 1:
        we can get following information after some simple operation.
        a. mkfs.ext4 /dev/vdh
           btrfs-convert /dev/vdh
        b. btrfs-debug-tree /dev/vdh
           we can see following item in extent tree:
           item 25 key (27054080 METADATA_ITEM 0) itemoff 15083 itemsize 33
           Its logical address is [27054080, 27070464)
           and acrossed 2 strips:
           [27000832, 27066368)
           [27066368, 27131904)
        Will be fixed in btrfs-progs(btrfs-convert, btrfsck, ...)

      For reason 2:
        Scrub is trying to do a "bypass" in this case, but the result is
        "panic", because current code lacks of some condition in bypass,
        and let some wrong leaf data escaped.

      This patch fixed above scrub code.

      Before patch:
        # btrfs scrub start -B /dev/vdh
        (panic)

      After patch:
        # btrfs scrub start -B /dev/vdh
        scrub done for 353cec8f-da31-4a94-aa35-be72d997b06e

      Btrfs: fix stale dir entries after removing a link and fsync

      We have one more case where after a log tree is replayed we get
      inconsistent metadata leading to stale directory entries, due to
      some directories having entries pointing to some inode while the
      inode does not have a matching BTRFS_INODE_[REF|EXTREF]_KEY item.

      To trigger the problem we need to have a file with multiple hard links
      belonging to different parent directories. Then if one of those hard
      links is removed and we fsync the file using one of its other links
      that belongs to a different parent directory, we end up not logging
      the fact that the removed hard link doesn't exists anymore in the
      parent directory.

      Simple reproducer:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

        _cleanup()
        {
            _cleanup_flakey

        }

        ln $SCRATCH_MNT/foo $SCRATCH_MNT/testdir/foo3

        # Make sure everything done so far is durably persisted.
        sync

        # Now we remove one of our file's hardlinks in the directory testdir.
        unlink $SCRATCH_MNT/testdir/foo3

        # We now fsync our file using the "foo" link, which has a parent that
        # is not the directory "testdir".
        $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/foo

        _mount_flakey

        # After the journal/log is replayed we expect to not see the "foo3"
        # link anymore and we should be able to remove all names in the
        # directory "testdir" and then remove it (no stale directory entries
        # left after the journal/log replay).
        echo "Entries in testdir:"
        ls -1 $SCRATCH_MNT/testdir

        rm -f $SCRATCH_MNT/testdir/*
        rmdir $SCRATCH_MNT/testdir

        _unmount_flakey

Aborting unused transaction(No such entry).

      So fix this by logging all parent inodes, current and old ones, to make
      sure we do not get stale entries after log replay. This is not a simple
      solution such as triggering a full transaction commit because it would
      imply full transaction commit when an inode is fsynced in the same
      transaction that modified it and reloaded it after eviction (because its
      last_unlink_trans is set to the same value as its last_trans as of the
      commit with the title "Btrfs: fix stale dir entries after unlink, inode
      eviction and fsync"), and it would also make fstest generic/066 fail
      since one of the fsyncs triggers a full commit and the next fsync will
      not find the inode in the log anymore (therefore not removing the xattr).

      btrfs: fix search key advancing condition

      The search key advancing condition used in copy_to_sk() is loose. It can
      advance the key even if it reaches sk->max_*: e.g. when the max key = 
(512,
      1024, -1) and the current key = (512, 1025, 10), it increments the
      offset by 1, continues hopeless search from (512, 1025, 11). This issue
      make ioctl() to take unexpectedly long time scanning all the leaf a blocks
      one by one.

      This commit fix the problem using standard way of key comparison:
      btrfs_comp_cpu_keys()

      Btrfs: teach backref walking about backrefs with underflowed offset values

      When cloning/deduplicating file extents (through the clone and extent_same
      ioctls) we can get data back references with offset values that are a
      result of an unsigned integer arithmetic underflow, that is, values that
      are much larger then they could be otherwise.

      This is not a problem when decrementing or dropping the back references
      (happens when we overwrite the extents or punch a hole for example, 
through
      __btrfs_drop_extents()), since we compute the same too large offset value,
      but it is a problem for the backref walking code, used by an incremental
      send and the ioctls that are used by the btrfs tool "inspect-internal"
      commands, as it makes it miss the corresponding file extent items because
      the search key is set for an extent item that starts at an offset matching
      the exceptionally large offset value of the data back reference. For an
      incremental send this causes the send ioctl to fail with -EIO.

      So teach the backref walking code to deal with these cases by setting the
      search key's offset to 0 if the backref's offset value is larger than
      LLONG_MAX (the largest possible file offset). This makes sure the backref
      walking code finds the corresponding file extent items at the expense of
      scanning more items and leafs in the btree.

      Fixing the clone/dedup ioctls to not produce such underflowed results 
would
      require major changes breaking backward compatibility, updating user space
      tools, etc.

      Simple reproducer case for fstests:

        #

        # that points to our initial extent with a data offset of 16K. The
        # corresponding data back reference in the extent tree has an offset of

      Btrfs: fix stale dir entries after unlink, inode eviction and fsync

      If we remove a hard link from an inode, the inode gets evicted, then
      we fsync the inode and then power fail/crash, when the log tree is
      replayed, the parent directory inode still has entries pointing to
      the name that no longer exists, while our inode no longer has the
      BTRFS_INODE_REF_KEY item matching the deleted hard link (as expected),
      leaving the filesystem in an inconsistent state. The stale directory
      entries can not be deleted (an attempt to delete them causes -ESTALE
      errors), which makes it impossible to delete the parent directory.

      This happens because we track the id of the transaction where the last
      unlink operation for the inode happened (last_unlink_trans) in an
      in-memory only field of the inode, that is, a value that is never
      persisted in the inode item stored on the fs/subvol btree. So if an
      inode is evicted and loaded again, the value for last_unlink_trans is
      set to 0, which prevents the fsync from logging the parent directory
      at btrfs_log_inode_parent(). So fix this by setting last_unlink_trans
      to the id of the transaction that last modified the inode when we
      load the inode. This is a pessimistic approach but it always ensures
      correctness with the trade off of ocassional full transaction commits
      when an fsync is done against the inode in the same transaction where
      it was evicted and reloaded when our inode is a directory and often
      logging its parent unnecessarily when our inode is not a directory.

      The following test case for fstests triggers the problem:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$

      Btrfs: fix stale directory entries after fsync log replay

      We have another case where after an fsync log replay we get an inode with
      a wrong link count (smaller than it should be) and a number of directory
      entries greater than its link count. This happens when we add a new link
      hard link to our inode A and then we fsync some other inode B that has
      the side effect of logging the parent directory inode too. In this case
      at log replay time we add the new hard link to our inode (the item with
      key BTRFS_INODE_REF_KEY) when processing the parent directory but we
      never adjust the link count of our inode A. As a result we get stale dir
      entries for our inode A that can never be deleted and therefore it makes
      it impossible to remove the parent directory (as its i_size can never
      decrease back to 0).

      A simple reproducer for fstests that triggers this issue:

        seq=`basename $0`
        seqres=$RESULT_DIR/$seq
        echo "QA output created by $seq"
        tmp=/tmp/$$
        status=1        # failure is the default!
        trap "_cleanup; exit \$status" 0 1 2 3 15

        _cleanup()
        {
            _cleanup_flakey
            rm -f $tmp.*
        }

        # get standard environment, filters and checks

        rm -f $seqres.full

        _scratch_mkfs >>$seqres.full 2>&1
        _init_flakey
        _mount_flakey

        # Create our test directory and files.
        mkdir $SCRATCH_MNT/testdir
        touch $SCRATCH_MNT/testdir/foo
        touch $SCRATCH_MNT/testdir/bar

        # Make sure everything done so far is durably persisted.
        sync

        # Create one hard link for file foo and another one for file bar. After
        # that fsync only the file bar.
        ln $SCRATCH_MNT/testdir/bar $SCRATCH_MNT/testdir/bar_link
        ln $SCRATCH_MNT/testdir/foo $SCRATCH_MNT/testdir/foo_link
        $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/testdir/bar

        # Silently drop all writes on scratch device to simulate power failure.
        _load_flakey_table $FLAKEY_DROP_WRITES
        _unmount_flakey

        # Allow writes again and mount the fs to trigger log/journal replay.
        _load_flakey_table $FLAKEY_ALLOW_WRITES
        _mount_flakey

        # Now verify both our files have a link count of 2.
        echo "Link count for file foo: $(stat --format=%h 
$SCRATCH_MNT/testdir/foo)"
        echo "Link count for file bar: $(stat --format=%h 
$SCRATCH_MNT/testdir/bar)"

        # We should be able to remove all the links of our files in testdir, and
        # after that the parent directory should become empty and therefore
        # possible to remove it.
        rm -f $SCRATCH_MNT/testdir/*
        rmdir $SCRATCH_MNT/testdir

        _unmount_flakey

        # The fstests framework will call fsck against our filesystem which 
will verify
        # that all metadata is in a consistent state.

        status=0
        exit

      The test fails with:

       -Link count for file foo: 2
       +Link count for file foo: 1
        Link count for file bar: 2
       +rm: cannot remove 
'/home/fdmanana/btrfs-tests/scratch_1/testdir/foo_link': Stale file handle
       +rmdir: failed to remove '/home/fdmanana/btrfs-tests/scratch_1/testdir': 
Directory not empty
       (...)
       _check_btrfs_filesystem: filesystem on /dev/sdc is inconsistent

      And fsck's output:

        (...)
        checking fs roots
        root 5 inode 258 errors 2001, no inode item, link count wrong
            unresolved ref dir 257 index 5 namelen 8 name foo_link filetype 1 
errors 4, no inode ref
        Checking filesystem on /dev/sdc
        (...)

      So fix this by marking inodes for link count fixup at log replay time
      whenever a directory entry is replayed if the entry was created in the
      transaction where the fsync was made and if it points to a non-directory
      inode.

      This isn't a new problem/regression, the issue exists for a long time,
      possibly since the log tree feature was added (2008).

      Packet condition has been detected, but before the end of the TD has been
      reached, (i.e. the TD is in progress for pipe), then a Transfer Event TRB
      with its Completion Code set to Stopped - Short Packet and its TRB
      Transfer Length set to value of the EDTLA shall be forced for the
      interrupted TRB, irrespective of whether its IOC or ISP flags are set.
      This Transfer Event TRB will precede the Command Completion Event TRB for
      the command, and is referred to as a Stopped Transfer Event.

      usb: xhci: make USB_XHCI_PLATFORM selectable

      Right now xhci-plat-hcd can be built when using one of platform specific
      drivers only (mvebu/rcar). There shouldn't be such limitation as some
      platforms may not require any quirks and may want to just use a generic
      driver ("generic-xhci" / "xhci-hcd").

      iio: Add inverse unit conversion macros

      Add inverse unit conversion macro to convert from standard IIO units to
      units that might be used by some devices.

      Those are useful in combination with scale factors that are specified as
      IIO_VAL_FRACTIONAL. Typically the denominator for those specifications 
will
      contain the maximum raw value the sensor will generate and the numerator
      the value it maps to in a specific unit. Sometimes datasheets specify 
those
      in different units than the standard IIO units (e.g. degree/s instead of
      rad/s) and so we need to do a unit conversion.

      From a mathematical point of view it does not make a difference whether we
      apply the unit conversion to the numerator or the inverse unit conversion
      to the denominator since (x / y) / z = x / (y * z). But as the denominator
      is typically a larger value and we are rounding both the numerator and
      denominator to integer values using the later method gives us a better
      precision (E.g. the relative error is smaller if we round 8000.3 to 8000
      rather than rounding 8.3 to 8).

      This is where in inverse unit conversion macros will be used.

      Marked for stable as used by some upcoming fixes.

      ARM: dts: rockchip: reserve unusable memory region on rk3288

      The all current Rockchip SoCs supporting 4GB of ram have problems 
accessing
      the memory region 0xfe000000~0xff000000. This also seems to includes the
      rk3368 arm64 soc.

      All current code handling dma memory oddities I could find, seem to 
involve
      soc-specific code (zone-dma or so) while this issue is shared between 
arm32
      and arm64 socs from Rockchip, which would need to have this described in
      the soc devicetree on both socs.

      Limiting the dma-zone alone also does not solve the issue and as the
      dma-masks need to be a power-of-two in the kernel, the next lower dma-mask
      brings memory usable for dma down to 2GB.

      So as a stop-gap block off the affected region to prevent its use by
      devices with 4GB of memory, like some recent Chromebooks.

      x86/vdso: Emit a GNU hash

      Some dynamic loaders may be slightly faster if a GNU hash is
      available.  Strangely, this seems to have no effect at all on
      the vdso size.

      This is unlikely to have any measurable effect on the time it
      takes to resolve vdso symbols (since there are so few of them).
      In some contexts, it can be a win for a different reason: if
      every DSO has a GNU hash section, then libc can avoid
      calculating SysV hashes at all.  Both musl and glibc appear to
      have this optimization.

      It's plausible that this breaks some ancient glibc version.  If
      so, then, depending on what glibc versions break, we could
      either require COMPAT_VDSO for them or consider reverting.

      powerpc/fsl: Force coherent memory on e500mc derivatives

      In CoreNet systems it is not allowed to mix M and non-M mappings to the
      same memory, and coherent DMA accesses are considered to be M mappings
      for this purpose.  Ignoring this has been observed to cause hard
      lockups in non-SMP kernels on e6500.

      Furthermore, e6500 implements the LRAT (logical to real address table)
      which allows KVM guests to control the WIMGE bits.  This means that
      KVM cannot force the M bit on the way it usually does, so the guest had
      better set it itself.

      powerpc/85xx: Use kconfig fragments

      Unify mpc85xx and corenet configs using fragments, to ease maintenance
      and avoid the sort of drift that the previous patch fixed.

      Hardware and software options are separated, with the hope that other
      embedded platforms could share the software options, and to make it
      easier to maintain custom/alternate configs that focus on either
      hardware or software options.

      Due to the previous patch, this patch should not affect the results of
      any of the affected defconfigs -- only how those results are achieved.
      The resulting config is more or less the union of the options that any
      of the configs previously selected.  No attempt was made in this (or

      will make it easier to do so in future patches.

      This adds the necessary data for handling io voltage domains on the 
rk3368.
      As interesting tidbit, the rk3368 contains two separate iodomain areas.
      One in the regular General Register Files (GRF) and one in PMUGRF in the

      PM / AVS: rockchip-io: depend on CONFIG_POWER_AVS

      The rockchip io-domain driver currently only depends on ARCH_ROCKCHIP
      itself. This makes it possible to select the power-domain driver, but
      not the POWER_AVS class and results in the iodomain-driver not getting
      build in this case.

      So add the additional dependency, which also results in the driver
      config option now being placed nicely into the AVS submenu.

      net: Fix race condition in store_rps_map

      There is a race condition in store_rps_map that allows jump label
      count in rps_needed to go below zero. This can happen when
      concurrently attempting to set and a clear map.

      Scenario:

      1. rps_needed count is zero
      2. New map is assigned by setting thread, but rps_needed count _not_ yet
         incremented (rps_needed count still zero)
      2. Map is cleared by second thread, old_map set to that just assigned
      3. Second thread performs static_key_slow_dec, rps_needed count now goes
         negative

      Fix is to increment or decrement rps_needed under the spinlock.

      - use a simple linear search to verify if a certain LCD controller

      Use the new helper in the ai (*insn_read) to ensure that the ai control
      register is set to a known state after reading the samples.

      The ai control register will now always be '0' after the (*cancel) of

      Sowmini Varadhan says:

      ====================
      RDS-TCP: Network namespace support

      This patch series contains the set of changes to correctly set up
      the infra for PF_RDS sockets that use TCP as the transport in multiple
      network namespaces.

      Patch 1 in the series is the minimal set of changes to allow
      a single instance of RDS-TCP to run in any (i.e init_net or other) net
      namespace.  The changes in this patch set ensure that the execution of
      'modprobe [-r] rds_tcp' sets up the kernel TCP sockets
      relative to the current netns, so that RDS applications can send/recv
      packets from that netns, and the netns can later be deleted cleanly.

      Patch 2 of the series further allows multiple RDS-TCP instances,
      one per network namespace. The changes in this patch allows dynamic
      creation/tear-down of RDS-TCP client and server sockets  across all
      current and future namespaces.

      v2 changes from RFC sent out earlier:
          David Ahern comments in patch 1, net_device notifier in patch 2,
          patch 3 broken off and submitted separately.
      v3: Cong Wang review comments.

      RDS-TCP: Support multiple RDS-TCP listen endpoints, one per netns.

      Register pernet subsys init/stop functions that will set up
      and tear down per-net RDS-TCP listen endpoints. Unregister
      pernet subusys functions on 'modprobe -r' to clean up these
      end points.

      Enable keepalive on both accept and connect socket endpoints.
      The keepalive timer expiration will ensure that client socket
      endpoints will be removed as appropriate from the netns when
      an interface is removed from a namespace.

      Register a device notifier callback that will clean up all
      sockets (and thus avoid the need to wait for keepalive timeout)
      when the loopback device is unregistered from the netns indicating
      that the netns is getting deleted.

      modsign: Use single PEM file for autogenerated key

      The current rule for generating signing_key.priv and signing_key.x509 is
      a classic example of a bad rule which has a tendency to break parallel
      make. When invoked to create *either* target, it generates the other
      target as a side-effect that make didn't predict.

      So let's switch to using a single file signing_key.pem which contains
      both key and certificate. That matches what we do in the case of an
      external key specified by CONFIG_MODULE_SIG_KEY anyway, so it's also
      slightly cleaner.

      MODSIGN: Use PKCS#7 messages as module signatures

      Move to using PKCS#7 messages as module signatures because:

       (1) We have to be able to support the use of X.509 certificates that 
don't
           have a subjKeyId set.  We're currently relying on this to look up the
           X.509 certificate in the trusted keyring list.

       (2) PKCS#7 message signed information blocks have a field that supplies 
the
           data required to match with the X.509 certificate that signed it.

       (3) The PKCS#7 certificate carries fields that specify the digest 
algorithm
           used to generate the signature in a standardised way and the X.509
           certificates specify the public key algorithm in a standardised way 
- so
           we don't need our own methods of specifying these.

       (4) We now have PKCS#7 message support in the kernel for signed kexec 
purposes
           and we can make use of this.

      To make this work, the old sign-file script has been replaced with a 
program
      that needs compiling in a previous patch.  The rules to build it are added
      here.

      MODSIGN: Provide a utility to append a PKCS#7 signature to a module

      Provide a utility that:

       (1) Digests a module using the specified hash algorithm (typically 
sha256).

           [The digest can be dumped into a file by passing the '-d' flag]

       (2) Generates a PKCS#7 message that:

           (a) Has detached data (ie. the module content).

           (b) Is signed with the specified private key.

           (c) Refers to the specified X.509 certificate.

           (d) Has an empty X.509 certificate list.

           [The PKCS#7 message can be dumped into a file by passing the '-p' 
flag]

       (3) Generates a signed module by concatenating the old module, the PKCS#7
           message, a descriptor and a magic string.  The descriptor contains 
the
           size of the PKCS#7 message and indicates the id_type as 
PKEY_ID_PKCS7.

       (4) Either writes the signed module to the specified destination or 
renames
           it over the source module.

      This allows module signing to reuse the PKCS#7 handling code that was 
added
      for PE file parsing for signed kexec.

      Note that the utility is written in C and must be linked against the 
OpenSSL
      crypto library.

      Note further that I have temporarily dropped support for handling 
externally
      created signatures until we can work out the best way to do those.  
Hopefully,
      whoever creates the signature can give me a PKCS#7 certificate.

      PKCS#7: Allow detached data to be supplied for signature checking purposes

      It is possible for a PKCS#7 message to have detached data.  However, to

      the signatures on a PKCS#7 message, we have to be able to digest the data.
      Provide a function to supply that data.  An error is given if the PKCS#7
      message included embedded data.

      This is used in a subsequent patch to supply the data to module signing 
where
      the signature is in the form of a PKCS#7 message with detached data, 
whereby
      the detached data is the module content that is signed.

      X.509: Support X.509 lookup by Issuer+Serial form AuthorityKeyIdentifier

      If an X.509 certificate has an AuthorityKeyIdentifier extension that 
provides
      an issuer and serialNumber, then make it so that these are used in 
preference
      to the keyIdentifier field also held therein for searching for the signing
      certificate.

      If both the issuer+serialNumber and the keyIdentifier are supplied, then 
the
      certificate is looked up by the former but the latter is checked as well. 
 If
      the latter doesn't match the subjectKeyIdentifier of the parent 
certificate,
      EKEYREJECTED is returned.

      This makes it possible to chain X.509 certificates based on the issuer and
      serialNumber fields rather than on subjectKeyIdentifier.  This is 
necessary as
      we are having to deal with keys that are represented by X.509 certificates
      that lack a subjectKeyIdentifier.

      Input: max77693: Add support for Maxim 77843

      The Maxim 77843 haptic driver differs from 77693 by:
      1. Setting the bias.
      2. Different configuration register.
      3. Not enabling the low-sys DAC.
      4. Using same regmap for PMIC and haptic blocks.

      Incorporate all differences into max77693 haptic driver so both devices
      can be supported.

      perf tests: Add LLVM test for eBPF on-the-fly compiling

      Previous patches introduce llvm__compile_bpf() to compile source file to
      eBPF object. This patch adds testcase to test it. It also tests libbpf
      by opening generated object after applying next patch which introduces
      HAVE_LIBBPF_SUPPORT option.

      Since llvm__compile_bpf() prints long messages which users who don't
      explicitly test llvm doesn't care, this patch set verbose to -1 to
      suppress all debug, warning and error message, and hint user use 'perf
      test -v' to see the full output.

      For the same reason, if clang is not found in PATH and there's no [llvm]
      section in .perfconfig, skip this test.

      perf tools: Auto detecting kernel include options

      To help user find correct kernel include options, this patch extracts
      them from kbuild system by an embedded script kinc_fetch_script, which
      creates a temporary directory, generates Makefile and an empty dummy.o
      then use the Makefile to fetch $(NOSTDINC_FLAGS), $(LINUXINCLUDE) and
      $(EXTRA_CFLAGS) options. The result is passed to compiler script using
      'KERNEL_INC_OPTIONS' environment variable.

      Because options from kbuild contains relative path like
      'Iinclude/generated/uapi', the work directory must be changed. This is
      done by previous patch.

      This patch detects kernel build directory by checking the existence of
      include/generated/autoconf.h.

      clang working directory is changed to kbuild directory if it is found,
      to help user use relative include path. Following patch will detect
      kernel include directory, which contains relative include patch so this
      workdir changing is needed.

      Users are allowed to set 'kbuild-dir = ""' manually to disable this
      checking.

      regmap: Use different lockdep class for each regmap init call

      Lockdep validator complains about recursive locking and deadlock
      when two different regmap instances are called in a nested order.
      That happens anytime a regmap read/write call needs to access
      another regmap.

      This is because, for performance reason, lockdep groups all locks
      initialized by the same mutex_init() in the same lock class.
      Therefore all regmap mutexes are in the same lock class, leading
      to lockdep "nested locking" warnings if a regmap accesses another
      regmap.

      In general, it is impossible to establish in advance the hierarchy
      of regmaps, so we make sure that each regmap init call initializes
      its own static lock_class_key. This is done by wrapping all
      regmap_init calls into macros.

      This also allows us to give meaningful names to the lock_class_key.
      For example, in rt5677 case, we have in /proc/lockdep_chains:
      irq_context: 0
      [ffffffc0018d2198] &dev->mutex
      [ffffffc0018d2198] &dev->mutex
      [ffffffc001bd7f60] rt5677:5104:(&rt5677_regmap)->_lock
      [ffffffc001bd7f58] rt5677:5096:(&rt5677_regmap_physical)->_lock
      [ffffffc001b95448] &(&base->lock)->rlock

      The above would have resulted in a lockdep recursive warning
      previously. This is not the case anymore as the lockdep validator
      now clearly identifies the 2 regmaps as separate.

        Commiter notice:

        When building with DEBUG=1 we get a compiler error that gets fixed with
        the same approach described in commit b236512280fb:

          The last argument to strtok_r doesn't need to be initialized, its

know
          about that and complains, breaking the build, fix it by setting it to
          NULL.

      caller). bpf_object__for_each_safe() is introduced to do this iteration.
      It is safe even user close the object during iteration.

      bpf tools: Introduce accessors for struct bpf_program

      This patch introduces accessors for user of libbpf to retrieve section
      name and fd of a opened/loaded eBPF program. 'struct bpf_prog_handler'
      is used for that purpose. Accessors of programs section name and file
      descriptor are provided. Set/get private data are also impelmented.

      bpf tools: Load eBPF programs in object files into kernel

      This patch utilizes previous introduced bpf_load_program to load
      programs in the ELF file into kernel. Result is stored in 'fd' field in
      'struct bpf_program'.

      During loading, it allocs a log buffer and free it before return.  Note
      that that buffer is not passed to bpf_load_program() if the first
      loading try is successful. Doesn't use a statically allocated log buffer
      to avoid potention multi-thread problem.

      Instructions collected during opening is cleared after loading.

      load_program() is created for loading a 'struct bpf_insn' array into
      kernel, bpf_program__load() calls it. By this design we have a function
      loads instructions into kernel. It will be used by further patches,
      which creates different instances from a program and load them into
      kernel.

      bpf tools: Relocate eBPF programs

      If an eBPF program accesses a map, LLVM generates a load instruction
      which loads an absolute address into a register, like this:

        ld_64   r1, <MCOperand Expr:(mymap)>
        ...
        call    2

      That ld_64 instruction will be recorded in relocation section.
      To enable the usage of that map, relocation must be done by replacing
      the immediate value by real map file descriptor so it can be found by
      eBPF map functions.

      This patch to the relocation work based on information collected by
      patches:

      'bpf tools: Collect symbol table from SHT_SYMTAB section',
      'bpf tools: Collect relocation sections from SHT_REL sections'
      and
      'bpf tools: Record map accessing instructions for each program'.

      For each instruction which needs relocation, it inject corresponding
      file descriptor to imm field. As a part of protocol, src_reg is set to
      BPF_PSEUDO_MAP_FD to notify kernel this is a map loading instruction.

      This is the final part of map relocation patch. The principle of map
      relocation is described in commit message of 'bpf tools: Collect symbol
      table from SHT_SYMTAB section'.

      bpf tools: Create eBPF maps defined in an object file

      This patch creates maps based on 'map' section in object file using
      bpf_create_map(), and stores the fds into an array in 'struct
      bpf_object'.

      Previous patches parse ELF object file and collects required data, but
      doesn't play with the kernel. They belong to the 'opening' phase. This
      patch is the first patch in 'loading' phase. The 'loaded' field is
      introduced in 'struct bpf_object' to avoid loading an object twice,
      because the loading phase clears resources collected during the opening
      which becomes useless after loading. In this patch, maps_buf is cleared.

      issuing bpf syscall. The goal of these two files is to hide syscall
      completely from user. Note that bpf.c and bpf.h deal with kernel

      is not cared by of bpf.[ch].

      We first introduce bpf_create_map().

      Note that, since functions in bpf.[ch] are wrapper of sys_bpf, they
      don't use OO style naming.

      bpf tools: Record map accessing instructions for each program

      This patch records the indices of instructions which are needed to be
      relocated. That information is saved in the 'reloc_desc' field in
      'struct bpf_program'. In the loading phase (this patch takes effect in
      the opening phase), the collected instructions will be replaced by map
      loading instructions.

      Since we are going to close the ELF file and clear all data at the end
      of the 'opening' phase, the ELF information will no longer be valid in
      the 'loading' phase. We have to locate the instructions before maps are
      loaded, instead of directly modifying the instruction.

      'struct bpf_map_def' is introduced in this patch to let us know how many
      maps are defined in the object.

      This is the third part of map relocation. The principle of map relocation
      is described in commit message of 'bpf tools: Collect symbol table from
      SHT_SYMTAB section'.

      bpf tools: Collect symbol table from SHT_SYMTAB section

      This patch collects symbols section. This section is useful when linking
      BPF maps.

      What 'bpf_map_xxx()' functions actually require are map's file
      descriptors (and the internal verifier converts fds into pointers to
      'struct bpf_map'), which we don't know when compiling. Therefore, we
      should make compiler generate a 'ldr_64 r1, <imm>' instruction, and
      fill the 'imm' field with the actual file descriptor when loading in
      libbpf.

      BPF programs should be written in this way:

       struct bpf_map_def SEC("maps") my_map = {
          .type = BPF_MAP_TYPE_HASH,
          .key_size = sizeof(unsigned long),
          .value_size = sizeof(unsigned long),
          .max_entries = 1000000,
       };

       SEC("my_func=sys_write")
       int my_func(void *ctx)
       {
           ...
           bpf_map_update_elem(&my_map, &key, &value, BPF_ANY);
           ...
       }

      Compiler should convert '&my_map' into a 'ldr_64, r1, <imm>'
      instruction, where imm should be the address of 'my_map'. According to
      the address, libbpf knows which map it actually referenced, and then
      fills the imm field with the 'fd' of that map created by it.

      However, since we never really 'link' the object file, the imm field is
      only a record in relocation section. Therefore libbpf should do the
      relocation:

       1. In relocation section (type == SHT_REL), positions of each such
          'ldr_64' instruction are recorded with a reference of an entry in
          symbol table (SHT_SYMTAB);

       2. From records in symbol table we can find the indics of map
          variables.

      Libbpf first record SHT_SYMTAB and positions of each instruction which
      required bu such operation. Then create file descriptor. Finally, after
      map creation complete, replace the imm field.

      This is the first patch of BPF map related stuff. It records SHT_SYMTAB
      into object's efile field for further use.

      bpf tools: Collect version and license from ELF sections

      Expand bpf_obj_elf_collect() to collect license and kernel version
      information in eBPF object file. eBPF object file should have a section
      named 'license', which contains a string. It should also have a section
      named 'version', contains a u32 LINUX_VERSION_CODE.

      bpf_obj_validate() is introduced to validate object file after loaded.
      Currently it only check existence of 'version' section.

      bpf tools: Check endianness and make libbpf fail early

      Check endianness according to EHDR. Code is taken from
      tools/perf/util/symbol-elf.c.

      Libbpf doesn't magically convert missmatched endianness. Even if we swap
      eBPF instructions to correct byte order, we are unable to deal with
      endianness in code logical generated by LLVM.

      Therefore, libbpf should simply reject missmatched ELF object, and let
      LLVM to create good code.

      bpf tools: Read eBPF object from buffer

      To support dynamic compiling, this patch allows caller to pass a
      in-memory buffer to libbpf by bpf_object__open_buffer(). libbpf calls
      elf_memory() to open it as ELF object file.

      Because __bpf_object__open() collects all required data and won't need
      that buffer anymore, libbpf uses that buffer directly instead of clone a
      new buffer. Caller of libbpf can free that buffer or use it do other
      things after bpf_object__open_buffer() return.

      bpf tools: Open eBPF object file and do basic validation

      This patch defines basic interface of libbpf. 'struct bpf_object' will
      be the handler of each object file. Its internal structure is hide to
      user. eBPF object files are compiled by LLVM as ELF format. In this
      patch, libelf is used to open those files, read EHDR and do basic
      validation according to e_type and e_machine.

      All elf related staffs are grouped together and reside in efile field of
      'struct bpf_object'. bpf_object__elf_finish() is introduced to clear it.

      After all eBPF programs in an object file are loaded, related ELF
      information is useless. Close the object file and free those memory.

      The zfree() and zclose() functions are introduced to ensure setting NULL
      pointers and negative file descriptors after resources are released.

      bpf tools: Allow caller to set printing function

      By libbpf_set_print(), users of libbpf are allowed to register he/she
      own debug, info and warning printing functions. Libbpf will use those
      functions to print messages. If not provided, default info and warning
      printing functions are fprintf(stderr, ...); default debug printing
      is NULL.

      This API is designed to be used by perf, enables it to register its own
      logging functions to make all logs uniform, instead of separated
      logging level control.

      bpf tools: Introduce 'bpf' library and add bpf feature check

      This is the first patch of libbpf. The goal of libbpf is to create a
      standard way for accessing eBPF object files. This patch creates
      'Makefile' and 'Build' for it, allows 'make' to build libbpf.a and
      libbpf.so, 'make install' to put them into proper directories.
      Most part of Makefile is borrowed from traceevent.

      Before building, it checks the existence of libelf in Makefile, and deny
      to build if not found. Instead of throwing an error if libelf not found,
      the error raises in a phony target "elfdep". This design is to ensure
      'make clean' still workable even if libelf is not found.

      Because libbpf requires 'kern_version' field set for 'union bpf_attr'
      (bpfdep" is used for that dependency), Kernel BPF API is also checked
      by intruducing a new feature check 'bpf' into tools/build/feature,
      which checks the existence and version of linux/bpf.h. When building
      libbpf, it searches that file from include/uapi/linux in kernel source
      tree (controlled by FEATURE_CHECK_CFLAGS-bpf). Since it searches kernel
      source tree it reside, installing of newest kernel headers is not
      required, except we are trying to port these files to an old kernel.

      To avoid checking that file when perf building, the newly introduced
      'bpf' feature check doesn't added into FEATURE_TESTS and
      FEATURE_DISPLAY by default in tools/build/Makefile.feature, but added
      into libbpf's specific.

      regulator: core: Drop regulator_list_mutex when we're done with it on 
remove

      When removing a regulator we hold regulator_list_mutex in order to
      ensure the regualtor doesn't become removed again.  However we only need
      to protect the list until we remove the regulator from the list so move
      the unlock earlier to reduce the locked region.

      we use for returning in the function kvm_arch_vm_ioctl instead
      of making r equal to zero when calling this particular function
      and incorrectly making the caller of kvm_arch_vm_ioctl think
      the function has run successfully.

      This patch adds a new NFTA_LIMIT_TYPE netlink attribute to indicate the 
type of
      limiting.

      Contrary to per-packet limiting, the cost is calculated from the packet 
path
      since this depends on the packet length.

      The burst attribute indicates the number of bytes in which the rate can be

      netfilter: nf_tables: add nft_dup expression

      This new expression uses the nf_dup engine to clone packets to a given 
gateway.
      Unlike xt_TEE, we use an index to indicate output interface which should 
be
      fine at this stage.

      Moreover, change to the preemtion-safe this_cpu_read(nf_skb_duplicated) 
from
      nf_dup_ipv{4,6} to silence a lockdep splat.

      Based on the original tee expression from Arturo Borrero Gonzalez, 
although
      this patch has diverted quite a bit from this initial effort due to the
      change to support maps.

      This series contains updates to i40e, i40evf and e1000e.

      Anjali adds support for x772 devices to i40e and i40evf.  With the added
      support, x772 supports offloading of the outer UDP transmit and receive
      checksum for tunneled packets.  Also supports evicting ATR filters in the
      hardware, so update the driver with this new feature set.

      Raanan provides several fixes for e1000e, first rectifies the Energy
      Efficient Ethernet in Sx code so that it only applies to parts that
      actually support EEE in Sx.  Fix whitespace and moved ICH8 related define
      to the proper context.  Fixed the ASPM locking which was reported by
      Bjorn Helgaas.  Fix a workaround implementation for systime which could
      experience a large non-linear increment of the systime value when
      checking for overflow.

      net_dbg_ratelimited: turn into no-op when !DEBUG

      The pr_debug family of functions turns into a no-op when -DDEBUG is not
      specified, opting instead to call "no_printk", which gets compiled to a
      no-op (but retains gcc's nice warnings about printf-style arguments).

      The problem with net_dbg_ratelimited is that it is defined to be a
      variant of net_ratelimited_function, which expands to essentially:

          if (net_ratelimit())
              pr_debug(fmt, ...);

      When DEBUG is not defined, then this becomes,

          if (net_ratelimit())
              ;

      This seems benign, except it isn't. Firstly, there's the obvious
      overhead of calling net_ratelimit needlessly, which does quite some book
      keeping for the rate limiting. Given that the pr_debug and
      net_dbg_ratelimited family of functions are sprinkled liberally through
      performance critical code, with developers assuming they'll be compiled
      out to a no-op most of the time, we certainly do not want this needless
      book keeping. Secondly, and most visibly, even though no debug message
      is printed when DEBUG is not defined, if there is a flood of
      invocations, dmesg winds up peppered with messages such as
      "net_ratelimit: 320 callbacks suppressed". This is because our
      aforementioned net_ratelimit() function actually prints this text in
      some circumstances. It's especially odd to see this when there isn't any
      other accompanying debug message.

      So, in sum, it doesn't make sense to have this function's current
      behavior, and instead it should match what every other debug family of
      functions in the kernel does with !DEBUG -- nothing.

      This patch replaces calls to net_dbg_ratelimited when !DEBUG with
      no_printk, keeping with the idiom of all the other debug print helpers.

      Also, though not strictly neccessary, it guards the call with an if (0)
      so that all evaluation of any arguments are sure to be compiled out.

      The second patch adds the possibility for tests to generate fragmented
      skbs.

      The third patch tests LD_ABS and LD_IND on fragmented skbs.

      The fourth patch adds the possibility to restrict the tests being run
      by specifying the name/id/range of the test(s) to run via module
      parameters.

      The fifth patch tests LD_ABS and LD_IND on non fragmented skbs with
      various sizes and alignments.

      The sixth and final patch checks that the interpreter or JIT correctly
      resets A and X to 0.

      This serie is against today's net-next tree.

      Changes in V2:

      ====================
      net/mlx5e: Driver updates 04-Aug-2015

      This patchset introduces two features to the ConnectX-4 driver: Patch 8/8
      ("Support physical port counters") exposes some hardware counters through
      ethtool. Rest of the patches are preparation and usage of what we call
      light-weight netdev open/close. Some flows that used to be in the 
ndo_open/stop
      are moved to the PCI probe/remove flows - i.e. we will make the netdev
      open/close operations more "light-weight".

      The benefits of this change are:
      1) Reduce the execution time of the stop/open operations.
      2) Avoid saving SW shadows of resource configurations that must
         persist through stop/open operations (e.g flow table steering
         rules), and avoid deleting/applying them from/to the device upon
         netdev stop/open.
      3) Avoid synchronizing threads that access those resources with the
         netdev stop/open threads.

      Instead of create/destroy the resource during netdev open/stop, This 
patchset
      changes the behavior such that upon netdev stop, traffic is redirected to 
a
      "Drop RQ" (a RQ that silently drops, at the NIC HW level all incoming 
traffic).
      After redirecting the traffic, RX/TX software resources could be 
destroyed.
      During netdev open, the RX/TX rings are created and traffic is redirected 
to
      the RX rings.

      Patchset was applied and tested over commit ba7591d ("ebpf: add skb->hash 
to
      offset map for usage in {cls, act}_bpf or filters")

      Now that TIRs, TISs and flow tables are kept alive while the netdev is
      stopped (after executing ndo_stop()) we can do the following
      improvements:

      - Obsolete the active_vlans SW shadow.
      - Do not delete/add flow table rules upon ndo_stop/open.
        In addition to simplifying the flow, this change also fastens
        the ndo_open/close operations.
      - Obsolete synchronization of threads accessing the flow tables
        with the netdev stop/open threads.

      Rename some functions that used to be invoked upon ndo_open/stop and

      Change some functions location in the file so that functions involved

      net/mlx5e: Unify the RX flow

      Generally an RX packet flows through the following objects:
      Flow table --> TIR --> RQT --> RQ

      Where:
      - TIR stands for "Transport Interface Receive", defining the RSS and
        LRO paramaters.
      - RQT stands for "RQ Table", implementing the RSS indirection table.
      - RQ stands for "Receive Queue"

      For flows that do not need LRO, nor RSS, the driver made a shortcut to
      the above RX flow by pointing to the RQ directly from the TIR, yielding
      this flow:
      Flow table --> TIR --> RQ

      In this commit we remove this shortcut by "inserting" a single-RQ RQT
      between the TIR and the RQ, i.e RX packets will reach the same RQ but
      will go through an RQT of size 1, pointing to just a single RQ.

      This way the RX traffic re-direction to/from the "Drop RQ" will be more
      uniform (AKA "one flow"), as it will involve only RQTs re-direction and
      no TIRs re-direction.

      We recently changed this code from returning NULL to returning ERR_PTR.
      There are some left over NULL assignments which we can remove.  We can
      preserve the error code from ip_route_output() instead of always
      returning -ENODEV.  Also these functions use a mix of gotos and direct
      returns.  There is no cleanup necessary so I changed the gotos to

      Do notice that this involves non-networking driver changes -

      cpufreq: dt: Add support for turbo/boost mode

      With opp-v2 DT bindings, few OPPs can be used only for the boost mode.
      But using such OPPs require the boost mode to be supported by cpufreq
      driver.

      We will parse DT bindings only during ->init() and so can enable boost
      support only after registering cpufreq driver.

      This enables boost support as soon as any policy has boost/turbo OPPs
      for its CPUs.

      We don't need to disable boost support as that is done by the core, when
      the driver is unregistered.

      cpufreq: Allow drivers to enable boost support after registering driver

      In some cases it wouldn't be known at time of driver registration, if
      the driver needs to support boost frequencies.

      For example, while getting boost information from DT with opp-v2
      bindings, we need to parse the bindings for all the CPUs to know if
      turbo/boost OPPs are supported or not.

      One way out to do that efficiently is to delay supporting boost mode
      (i.e. creating /sys/devices/system/cpu/cpufreq/boost file), until the
      time OPP bindings are parsed.

      At that point, the driver can enable boost support. This can be done at
      ->init(), where the frequency table is created.

      To do that, the driver requires few APIs from cpufreq core that let him
      do this. This patch provides these APIs.

      PM / OPP: Add support for opp-suspend

      With "operating-points-v2" bindings, it's possible to specify the OPP to
      which the device must be switched, before suspending.

      This patch adds support for getting that information.

      PM / OPP: Add OPP sharing information to OPP library

      An opp can be shared by multiple devices, for example its very common
      for CPUs to share the OPPs, i.e. when they share clock/voltage rails.

      This patch adds support of shared OPPs to the OPP library.

      Instead of a single device, dev_opp will now contain a list of devices
      that use it. It also senses if the device (we are trying to initialize
      OPPs for) shares OPPs with a device added earlier and in that case we
      update the list of devices managed by OPPs instead of duplicating OPPs
      again.

      The same infrastructure will be used for the old OPP bindings, with
      later patches.

      PM / OPP: Add support to parse "operating-points-v2" bindings

      This adds support in OPP library to parse and create list of OPPs from
      operating-points-v2 bindings. It takes care of most of the properties of
      new bindings (except shared-opp, which will be handled separately).

      For backward compatibility, we keep supporting earlier bindings. We try

      look for the old deprecated ones.

      There are few things marked as TODO:
      - Support for multiple OPP tables
      - Support for multiple regulators

      They should be fixed separately.

      Later commits would add support for new OPP bindings and this would be

      Another change worth noticing is INIT_LIST_HEAD(&opp->node). We weren't
      doing it earlier as we never tried to delete a list node before it is
      added to list. But this wouldn't be the case anymore. We might try to
      delete a node (just to reuse the same code paths), without it being
      getting added to the list.

      ACPI: fix acpi_debugfs_init prototype

      acpi_debugfs_init function is declared with return type int in
      drivers/acpi/internal.h when CONFIG_DEBUG_FS is enabled, but its
      definition in drivers/acpi/debugfs.c has return type void. This is due
      to commit aecad432fd68 ("ACPI: Cleanup custom_method debug stuff"),
      which changed the return type from int to void without updating the
      declaration.

      Fix this inconsistency by updating acpi_debugfs_init prototype.  While
      at it, include internal.h in debugfs.c so that the compiler can check
      that the declaration and definition remain compatible.

      ACPI / sysfs: Update method tracing facility.

      This patch updates the method tracing facility as the acpi_debug_trace()
      API has been updated to allow it to trace AML interpreter execution, the
      meanings and the usages of the API parameters are changed due to the
      updates.

      The new API:
      1. Uses ACPI_TRACE_ENABLED flag to indicate the enabling of the tracer;
      2. Allows tracer still can be enabled when method name is not specified so
         that the AML interpreter execution can be traced without knowing the
         method name, which is useful for kernel boot tracing;
      3. Supports arbitrary full path name, it doesn't need to be a name related
         to an entrance of acpi_evaluate_object().

      Note that the sysfs parameters are also updated so that when reading the
      attribute files, ACPICA internal settings are returned.

      In order to make the sysfs parameters (acpi.trace_state) available during
      boot, this patch adds code to bypass ACPICA semaphore/mutex invocations
      when acpi mutex utilities haven't been initialized.

      This patch doesn't update documentation of method tracing facility, it 
will
      be updated by further patches.

      audit: implement audit by executable

      This adds the ability audit the actions of a not-yet-running process.

      This patch implements the ability to filter on the executable path.  
Instead of
      just hard coding the ino and dev of the executable we care about at the 
moment
      the rule is inserted into the kernel, use the new audit_fsnotify
      infrastructure to manage this dynamically.  This means that if the 
filename
      does not yet exist but the containing directory does, or if the inode in
      question is unlinked and creat'd (aka updated) the rule will just 
continue to
      work.  If the containing directory is moved or deleted or the filesystem 
is
      unmounted, the rule is deleted automatically.  A future enhancement would 
be to
      have the rule survive across directory disruptions.

      This is a heavily modified version of a patch originally submitted by Eric
      Paris with some ideas from Peter Moody.

      audit: clean simple fsnotify implementation

      This is to be used to audit by executable path rules, but audit watches 
should
      be able to share this code eventually.

      At the moment the audit watch code is a lot more complex.  That code only
      creates one fsnotify watch per parent directory.  That 'audit_parent' in
      turn has a list of 'audit_watches' which contain the name, ino, dev of
      the specific object we care about.  This just creates one fsnotify watch
      per object we care about.  So if you watch 100 inodes in /etc this code
      will create 100 fsnotify watches on /etc.  The audit_watch code will
      instead create 1 fsnotify watch on /etc (the audit_parent) and then 100
      individual watches chained from that fsnotify mark.

      We should be able to convert the audit_watch code to do one fsnotify
      mark per watch and simplify things/remove a whole lot of code.  After
      that conversion we should be able to convert the audit_fsnotify code to
      support that hierarchy if the optimization is necessary.

      Move the access to the entry for audit_match_signal() to the beginning of
      the audit_del_rule() function in case the entry found is the same one 
passed
      in.  This will enable it to be used by audit_autoremove_mark_rule(),
      kill_rules() and audit_remove_parent_watches().

      This is a heavily modified and merged version of two patches originally
      submitted by Eric Paris.

      Currently the value of a PMU config term is silently truncated if it is
      too big. This is an impediment to validating the value for other
      criteria later on i.e.  the user provides an invalid value that gets
      truncated to a valid one.

      The maximum value validation is only done for the parser where the error
      is passed back to the user. In other cases the silent truncation
      continues so as not to affect tools that perhaps rely on it.

      perf top: Add branch annotation code to top

      Now that we can process branch data in annotate it makes sense to
      support enabling branch recording from top too. Most of the code needed
      for this is already in shared code with report. But we need to add:

      - The option parsing code (using shared code from the previous patch)
      - Document the options
      - Set up the IPC/cycles accounting state in the top session
      - Call the accounting code in the hist iter callback

      perf annotate: Finally display IPC and cycle accounting

      Add two new columns to the annotate display and display the average
      cycles and the compute IPC if available.

      When the LBR was not in any branch mode the IPC computation is
      automatically disabled. We still display the cycle information.

      Example output (with made up numbers):

      The second column is the IPC and third average cycles.

      perf annotate: Compute IPC and basic block cycles

      Compute the IPC and the basic block cycles for the annotate display.

      IPC is computed by counting the instructions, and then dividing the
      accounted cycles by that count.

      The actual IPC computation can only be done at annotate time, because we
      need to parse the objdump output first to know the number of
      instructions in the basic block.

      The cycles/IPC are also put into the perf function annotation so that
      the display code can show them.

      Again basic block overlaps are not handled, with the longest winning,
      but there are some heuristics to hide the IPC when the longest is not
      the most common.

      v2: Compute IPC correctly.

      perf report: Add infrastructure for a cycles histogram

      This adds the basic infrastructure to keep track of cycle counts per
      basic block for annotate. We allocate an array similar to the normal
      accounting, and then account branch cycles there.

      We handle two cases:

      cycles per basic block with start and cycles per branch (these are later
      used for either IPC or just cycles per BB)

      In the start case we cannot handle overlaps, so always the longest basic
      block wins.

      For the cycles per branch case everything is accurately accounted.

      v2: Remove unnecessary checks. Slight restructure. Move
      symbol__get_annotation to another patch. Move histogram allocation.
      v3: Merged with current tree

      perf tools: Add support for cycles, weight branch_info field

      cycles is a new branch_info field available on some CPUs that indicates
      the time deltas between branches in the LBR.

      Add a sort key and output code for the cycles to allow to display the
      basic block cycles individually in perf report.

      We also pass in the cycles for weight when LBRs are processed, which
      allows to get global and local weight, to get an estimate of the total
      cost.

      And also print the cycles information for perf report -D.  I also added
      printing for the previously missing LBR flags (mispredict etc.)

      scripts/kernel-doc Allow struct arguments documentation in struct body

      Describing arguments at top of a struct definition works fine
      for small/medium size structs, but it definitely doesn't work well
      for struct with a huge list of elements.

      Keeping the arguments list inside the struct body makes it easier
      to maintain the documentation.
      ie:
      /**
       * struct my_struct - short description
       * @a: first member
       * @b: second member
       *
       * Longer description
       */
      struct my_struct {
          int a;
          int b;
          /**
           * @c: This is longer description of C
           *
           * You can use paragraphs to describe arguments
           * using this method.
           */
          int c;
      };

      This patch allows the use of this kind of syntax. Only one argument
      per comment and user can use how many paragraphs he needs. It should
      start with /**, which is already being used by kernel-doc. If those
      comment doesn't follow those rules, it will be ignored.

      tracing, perf: Implement BPF programs attached to uprobes

      By copying BPF related operation to uprobe processing path, this patch
      allow users attach BPF programs to uprobes like what they are already
      doing on kprobes.

      After this patch, users are allowed to use PERF_EVENT_IOC_SET_BPF on a
      uprobe perf event. Which make it possible to profile user space programs
      and kernel events together using BPF.

      Because of this patch, CONFIG_BPF_EVENTS should be selected by
      CONFIG_UPROBE_EVENT to ensure trace_call_bpf() is compiled even if
      KPROBE_EVENT is not set.

      bpf: Use correct #ifdef controller for trace_call_bpf()

      Commit e1abf2cc8d5d80b41c4419368ec743ccadbb131e ("bpf: Fix the build on
      BPF_SYSCALL=y && !CONFIG_TRACING kernels, make it more configurable")
      updated the building condition of bpf_trace.o from CONFIG_BPF_SYSCALL
      to CONFIG_BPF_EVENTS, but the corresponding #ifdef controller in
      trace_events.h for trace_call_bpf() was not changed. Which, in theory,
      is incorrect.

      With current Kconfigs, we can create a .config with CONFIG_BPF_SYSCALL=y
      and CONFIG_BPF_EVENTS=n by unselecting CONFIG_KPROBE_EVENT and
      selecting CONFIG_BPF_SYSCALL. With these options, trace_call_bpf() will
      be defined as an extern function, but if anyone calls it a symbol missing
      error will be triggered since bpf_trace.o was not built.

      This patch changes the #ifdef controller for trace_call_bpf() from
      CONFIG_BPF_SYSCALL to CONFIG_BPF_EVENTS. I'll show its correctness:

      Before this patch:

         BPF_SYSCALL   BPF_EVENTS   trace_call_bpf   bpf_trace.o
         y             y           normal           compiled
         n             n           inline           not compiled
         y             n           normal           not compiled (incorrect)
         n             y          impossible (BPF_EVENTS depends on BPF_SYSCALL)

      After this patch:

         BPF_SYSCALL   BPF_EVENTS   trace_call_bpf   bpf_trace.o
         y             y           normal           compiled
         n             n           inline           not compiled
         y             n           inline           not compiled (fixed)
         n             y          impossible (BPF_EVENTS depends on BPF_SYSCALL)

      So this patch doesn't break anything. QED.

      mtd: spi-nor: fsl-quadspi: i.MX6SX: fixed the random QSPI access failed 
issue

      We found there is a low probability(5%) QSPI access timeout issue,
      usually it happened on kernel boot stage, the first time kernel tried to
      access QSPI chip. The READ_ID command was sent but not executed,
      consequently the probe function failed.

      The root cause is that the divider is not glitchless in i.MX6SX chip.
      If qspi clock enabled then change clock frequency by call clk_set_rate,
      there will be glitch at low possiblity rate and pass to qspi controller.
      The controler will be hang by this glitch.

      Based on the new clock flag(CLK_SET_RATE_GATE) and new framework, we
      need to change the approach of seting clock rate.
      1. Disable clock.
      2. call clk_set_rate.
      3. Enable clock again.

      mtd: spi-nor: fsl-quadspi: dynamically map memory space for AHB read

      QSPI may failed to map enough memory (256MB) for AHB read in
      previous implementation, especially in 3G/1G memory layout kernel.
      Dynamically map memory to avoid such issue.

      This implementation generally map QUADSPI_MAX_IOMAP (default 4MB) memory
      for AHB read, it should be enough for common scenarios, and the side
      effect (0.6% performance drop) is minor.

      usb: gadget: add 'ep_match' callback to usb_gadget_ops

      Add callback that is called by epautoconf to allow UDC driver match the
      best endpoint for specific descriptor. It's intended to supply mechanism
      which allows to get rid of chip-specific endpoint matching code from
      epautoconf.

      If gadget has set 'ep_match' callback we prefer to call it first, and
      if it fails to find matching endpoint, then we try to use default matching
      algorithm.

      perf trace: Add total time column to summary.

      It is cumbersome to manually calculate the total time spent in a given
      syscall by multiplying the average value with the number of calls.

      Instead, we now do this directly inside perf trace.

      Note that this is also done by 'strace', which even adds a column with
      relative numbers - something we could do in the future.

      Example:

        perf trace -s find /some/folder > /dev/null

         Summary of events:

         find (19976), 700123 events, 100.0%, 0.000 msec

      iommu/io-pgtable-arm: Centralise sync points

      With all current users now opted in to DMA API operations, make the
      iommu_dev pointer mandatory, rendering the flush_pgtable callback
      redundant for cache maintenance. However, since the DMA calls could be
      nops in the case of a coherent IOMMU, we still need to ensure the page
      table updates are fully synchronised against a subsequent page table
      walk. In the unmap path, the TLB sync will usually need to do this
      anyway, so just cement that requirement; in the map path which may
      consist solely of cacheable memory writes (in the coherent case),
      insert an appropriate barrier at the end of the operation, and obviate
      the need to call flush_pgtable on every individual update for
      synchronisation.

      iommu/io-pgtable-arm: Allow appropriate DMA API use

      Currently, users of the LPAE page table code are (ab)using dma_map_page()
      as a means to flush page table updates for non-coherent IOMMUs. Since
      from the CPU's point of view, creating IOMMU page tables *is* passing
      DMA buffers to a device (the IOMMU's page table walker), there's little
      reason not to use the DMA API correctly.

      Allow IOMMU drivers to opt into DMA API operations for page table
      allocation and updates by providing their appropriate device pointer.
      The expectation is that an LPAE IOMMU should have a full view of system
      memory, so use streaming mappings to avoid unnecessary pressure on
      ZONE_DMA, and treat any DMA translation as a warning sign.

      drm: Add top level Kconfig option for DRM fbdev emulation

      Legacy fbdev emulation support via DRM is achieved through KMS FB helpers.
      Most modesetting drivers enable provide fbdev emulation by default by
      selecting KMS FB helpers. A few provide a separate Kconfig option for the
      user to enable or disbale fbdev emulation.

      Enabling fbdev emulation is finally a distro-level decision. Having a top
      level Kconfig option for fbdev emulation helps by providing a uniform way
      to enable/disable fbdev emulation for any modesetting driver. It also lets
      us remove unnecessary driver specific Kconfig options that causes bloat.

      With a top level Kconfig in place, we can stub out the fb helper functions
      when not needed without breaking functionality. Having stub functions also
      prevents drivers to require wrapping fb helper function calls with 
#ifdefs.

      DRM_FBDEV_EMULATION defaults to y since many drivers enable fbdev
      emulation by default and majority of distributions expect the fbdev
      interface in the kernel.

      drm/fbdev: Return -EBUSY when oopsing

      Trying to do anything with kms drivers when oopsing has become a
      failing proposition. But since we can end up in the fbdev code simply
      due to the console unblanking that's done unconditionally just
      removing our panic handler isn't enough. We need to block all fbdev
      callbacks when oopsing.

      There was already one in the blank handler, but it failed silently.
      That makes it impossible for drivers (like i915) who subclass these
      functions to figure this out.

      Instead consistently return -EBUSY so that everyone knows that we
      really don't want to be bothered right now. This also allows us to
      remove a pile of FIXMEs from the i915 fbdev code (since due to the
      failure code they now won't attempt to grab dangerous locks any more).

      drm/fb_helper: Add drm_fb_helper functions to manage fb_info creation

      Every drm driver calls framebuffer_alloc, fb_alloc_cmap,
      unregister_framebuffer, fb_dealloc_cmap and framebuffer_release in

      Create drm_fb_helper functions that perform the above operations.

      This is part of an effort to prevent drm drivers from calling fbdev
      functions directly. It also removes repetitive code from drivers.

      There are some drivers that call alloc_apertures after framebuffer_alloc
      and some that don't. Make the helper always call alloc_apertures. This
      would make certain drivers allocate memory for apertures but not use
      them. Since it's a small amount of memory, it shouldn't be an issue.

      ARM: rockchip: set correct stabilization thresholds in suspend

      Currently the stabilization thresholds for the oscillator and external pmu
      are statically set to 30ms based on a 32kHz clock rate. This leaves out 
the
      case when we don't switch to the 32kHz clock when only entering the 
shallow
      suspend mode where the logic keeps running.

      So, set the correct threshold after we have determined if we switch to the
      32kHz clock or stay with the 24MHz one. Also set the oscillator-
      stabilization to 0 if it is kept running during suspend, as it of course
      does not need to stabilize then.

      ARM: rockchip: rename osc_switch_to_32k variable

      The variable name is misleading, as the deep suspend mode always switches
      the main supplying clock to the 32kHz source. Additionally the main
      oscillator remains running in some cases, which this var indicates.

      So rename it to osc_disable to clarity.

      clockevents/drivers/em_sti: Migrate to new 'set-state' interface

      Migrate em_sti driver to the new 'set-state' interface provided by
      the clockevents core, the earlier 'set-mode' interface is marked
      obsolete now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      NOTE: This also drops a special check:

        if (old_mode == CLOCK_EVT_MODE_ONESHOT)
                em_sti_stop(p, USER_CLOCKEVENT);

      as it doesn't look like that important. This driver only supports
      ONESHOT and we can only move only to SHUTDOWN from ONESHOT and.
      Also on second call (on shutdown), em_sti_stop() would return without
      disabling the device again.

      Existing implementation checks all divider values and tracks
      'red' proximity value for the frequency.

      But as divider array is monotonically increasing the first
      divider that gives DMIC rate in 3MHz range is the best one
      we should use. No need for 'red' zone tracking.

      Additionally make sure that DMIC frequency is higher 1MHz.

      ARM: ux500: simplify secondary CPU boot

      This removes a lot of ancient cruft from the Ux500 SMP boot.
      Instead of the pen grab/release, just point the ROM to
      secondary_boot() and start the second CPU there, then send
      the IPI.

      Use our own SMP enable method. This enables us to remove the
      last static mapping and get both CPUs booting properly.

      Tested this and it just works.

      ARM: dts: am437x-gp-evm: Add regulator-always-on and regulator-boot-on 
for RTC DCDCs

      DCDC5 and DCDC6 supply rtc and need to be on for accessing the module.

      On A1 revision of the TPS65218, FSEAL bit would be undefined without
      coin-cell present which in many cases led to it being set, causing DCDC5
      and DCDC6 to stay active, but also leading to unexplained failures when
      it was not. On B1 revision, FSEAL is always 0 when no coin-cell is present
      so this patch is required on boards with B1 revision to ever work. This
      implementation works on boards with either A1 or B1 revision and makes
      sure that DCDC5 and DCDC6 always stay active.

      For PCIe/USB chipsets, preallocated skb buffers are reused for

      Preallocated event SKBs are getting reused for PCIe chipset.
      Their physical addresses are shared with firmware so that

      mwifiex: fix system crash observed during initialisation

      System crash was observed if one of the driver initialisation
      commands is timed out. The reason is our timeout handler triggers
      firmware dump, meanwhile driver initialisation error paths have
      already freed the adapter structure.

      Firmware hasn't yet completely initialized. So collecting firmware
      dump is not needed in this case. Command timeout handler is
      modified in this patch to fix the crash issue.

      We enable Rx data by updating RX ring read pointer in

      mwifiex: simplify mwifiex_complete_cmd

      600f5d909a54("mwifiex: cleanup ioctl wait queue and abstraction layer")
      introduced the wakeup_interruptible suppression in mwifiex_complete_cmd
      b1a47aa5e1e1("mwifiex: fix system hang issue in cmd timeout error case")
      then added wakup_interruptible to mwifiex_cmd_timeout_func the single
      place setting a status of ETIMEDOUT.
      Instead of doing extra work, using the standard call-chain will have the
      same effect:
      mwifiex_cancel_pending_ioctl
      -> mwifiex_recycle_cmd_node
      -> mwifiex_insert_cmd_to_free_q
      -> mwifiex_complete_cmd
      -> wake_up_interruptible

      The difference is that previously the condition was not set to true,
      but that's probably just an oversight in b1a47aa5e1e1 and shouldn't
      have any consequence

      mwifiex: remove CMD_F_CANCELED flag

      CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
      case it already started or starts processing the cmd.
      But this was probably not working the way intended:
      - it is racy: mwifiex_process_cmdresp might already have passed that
        test and is continuing to use the cmd node being recycled
      - mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
        we just set to NULL
      - mwifiex_recycle_cmd_node will clear the flag

      The reason why it probably works is that mwifiex_cancel_pending_ioctl
      is only called from mwifiex_cmd_timeout_func, where the there is little
      chance of a command response still arriving

      Allow network stack part of Rx processing to run on separate core,
      relaxing CPU utilization on the core used for Rx NAPI.

      If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
      to enable RPS. The core for processing the rx skb is determined by RPS
      mechanism according to rx_cpus bit mask which is configured at user level.
      For processing skbs on different core from the core which processes
      the interrupts, it is recommended not to enable core 0 in rx_cpus bit 
mask.

      wil6210: use inline functions for register access

      Replace macros like "R", "W", "S", "C", defined multiple times,
      with inline functions "wil_[rwsc]".

      Use "readl" and "writel" instead of "ioread32" and "iowrite32"
      since it is granted that memory transactions are used,
      not port ones like IN/OUT

      wil6210: remove 3-MSI support

      In the recent kernel versions, multiple MSI is not well supported.
      In particular, it is not supported on x86 and ARM architectures.
      Also, internal interrupt handling logic is simpler and
      more effective when using single interrupt.

      Remove support for 3 MSI, convert module parameter
      "use_msi" from int with range [0,1,3] to boolean.

      The test flow is like below:
      1. pwrite foo -S 0xaa 0 64K
      2. pwrite foo -S 0xbb 64K 61K
      3. sync

      5. truncate foo 125K
      6. fsync foo
      7. flakey drop writes
      8. umount

      After this test, we expect the data of recovered file will have the first
      64k of data filling with value 0xaa and the next 61k of data filling with
      value 0x00 because we have fsynced it before dropping writes in dm.

      In f2fs, during recovering, we will only recover the valid block address
      in direct node page if it is marked as a fsynced dnode, but block address
      which means invalid/reserved (with value NULL_ADDR/NEW_ADDR) will not be
      recovered. So, the file recovered shows its incorrect data 0xbb in range 
of
      [61k, 125k].

      In this patch, we fix to recover invalid/reserved block during recover 
flow.

      powerpc/powernv: Invoke opal_cec_reboot2() on unrecoverable machine check 
errors.

      On non-recoverable MCE errors in kernel space, Linux kernel panics
      and system reboots. On BMC based system opal-prd runs as a daemon
      in the host. Hence, kernel crash may prevent opal-prd to detect and
      analyze this MCE error. This may land us in a situation where the faulty
      memory never gets de-configured and Linux would keep hitting same MCE 
error
      again and again. If this happens in early stage of kernel initialization,
      then Linux will keep crashing and rebooting in a loop.

      This patch fixes this issue by invoking new opal_cec_reboot2() call with
      reboot type OPAL_REBOOT_PLATFORM_ERROR to inform BMC/OCC about this
      error, so that BMC can collect relevant data for error analysis and
      decide what component to de-configure before rebooting.

      This patch is dependent on OPAL patchset posted on skiboot mailing list
      at https://lists.ozlabs.org/pipermail/skiboot/2015-July/001771.html that
      introduces opal_cec_reboot2() opal call.

      dmaengine: Add scatter-gathered memset

      The current API allows the driver to accelerate memset by using the DMA
      controller.

      However, it does so over a contiguous memory area, which might proves
      inefficient when you have to do it over a non-contiguous yet repititive
      pattern, since you have to create a number of descriptors and then submit
      each other.

      Add a memset operation going over a scatter list to handle such cases in a
      single call.

      driver core: correct device's shutdown order

      Now device's shutdown sequence is performed in reverse order of their
      registration in devices_kset list and this sequence corresponds to the
      reverse device's creation order. So, devices_kset data tracks
      "parent<-child" device's dependencies only.

      Unfortunately, that's not enough and causes problems in case of
      implementing board's specific shutdown procedures. For example [1]:
      "DRA7XX_evm uses PCF8575 and one of the PCF output lines feeds to
      MMC/SD and this line should be driven high in order for the MMC/SD to
      be detected. This line is modelled as regulator and the hsmmc driver
      takes care of enabling and disabling it. In the case of 'reboot',
      during shutdown path as part of it's cleanup process the hsmmc driver
      disables this regulator. This makes MMC boot not functional."

      To handle this issue the .shutdown() callback could be implemented
      for PCF8575 device where corresponding GPIO pins will be configured to
      states, required for correct warm/cold reset. This can be achieved
      only when all .shutdown() callbacks have been called already for all
      PCF8575's consumers. But devices_kset is not filled correctly now:

      devices_kset: Device61 4e000000.dmm
      devices_kset: Device62 48070000.i2c
      devices_kset: Device63 48072000.i2c
      devices_kset: Device64 48060000.i2c
      devices_kset: Device65 4809c000.mmc
      ...
      devices_kset: Device102 fixedregulator-sd
      ...
      devices_kset: Device181 0-0020 // PCF8575
      devices_kset: Device182 gpiochip496
      devices_kset: Device183 0-0021 // PCF8575
      devices_kset: Device184 gpiochip480

      As can be seen from above .shutdown() callback for PCF8575 will be called
      before its consumers, which, in turn means, that any changes of PCF8575
      GPIO's pins will be or unsafe or overwritten later by GPIO's consumers.
      The problem can be solved if devices_kset list will be filled not only
      according device creation order, but also according device's probing
      order to track "supplier<-consumer" dependencies also.

      Hence, as a fix, lets add devices_kset_move_last(),
      devices_kset_move_before(), devices_kset_move_after() and call them
      from device_move() and also add call of devices_kset_move_last() in
      really_probe(). After this change all entries in devices_kset will
      be sorted according to device's creation ("parent<-child") and
      probing ("supplier<-consumer") order.

      devices_kset after:
      devices_kset: Device121 48070000.i2c
      devices_kset: Device122 i2c-0
      ...
      devices_kset: Device147 regulator.24
      devices_kset: Device148 0-0020
      devices_kset: Device149 gpiochip496
      devices_kset: Device150 0-0021
      devices_kset: Device151 gpiochip480
      devices_kset: Device152 0-0019
      ...
      devices_kset: Device372 fixedregulator-sd
      devices_kset: Device373 regulator.29
      devices_kset: Device374 4809c000.mmc
      devices_kset: Device375 mmc0

      cpu: Remove bogus __ref annotation of cpu_subsys_online()

      In commit 0db0628d9012 ("kernel: delete __cpuinit usage from all core
      kernel files") cpu_up() lost its __cpuinit annotation, vanishing the
      need for cpu_subsys_online() to have a __ref annotation. Just drop it
      to be able to catch real section mismatches in the future.

      This patch adds just consumers part of the framework just to enable easy
      review.

      Up until now, nvmem drivers were stored in drivers/misc, where they all
      had to duplicate pretty much the same code to register a sysfs file,
      allow in-kernel users to access the content of the devices they were
      driving, etc.

      This was also a problem as far as other in-kernel users were involved,
      since the solutions used were pretty much different from on driver to
      another, there was a rather big abstraction leak.

      This introduction of this framework aims at solving this. It also
      introduces DT representation for consumer devices to go get the data they
      require (MAC Addresses, SoC/Revision ID, part numbers, and so on) from
      the nvmems.

      Having regmap interface to this framework would give much better
      abstraction for nvmems on different buses.

      auxdisplay: ks0108: fix refcount

      parport_find_base() will implicitly do parport_get_port() which
      increases the refcount. Then parport_register_device() will again
      increment the refcount. But while unloading the module we are only
      doing parport_unregister_device() decrementing the refcount only once.
      We add an parport_put_port() to neutralize the effect of
      parport_get_port().

      coresight-etm3x: Support context-ID tracing when PID namespace is enabled

      The Coresight ETM drivers already support context-ID tracing, but it won't
      work when PID namespace is enabled. This is because when using PID
      namespace a process id (ie. VPID) seen from the current namespace differs
      from the id (ie. PID) seen by kernel.

      So when users write the process id seen by themselves to ETM, there needs
      to be a translation from VPID to PID, as such ETM drivers will write the
      PID into the Context ID register correctly.

      If PID namespace is enabled, everytime users configure the Context ID

      This binding is horrible and never should have been merged. It is not

      break anything we care about. Lets revert it before we do have users.

      The problems with it are:

      - It is not documented.

      - The GPIO connection is described with a custom property and uses Linux
      GPIO numbering.

      - The UART connection is described using the Linux tty device name.

      xprtrdma: take HCA driver refcount at client

      This is a rework of the following patch sent almost a year back:
      http://www.mail-archive.com/linux-rdma%40vger.kernel.org/msg20730.html

      In presence of active mount if someone tries to rmmod vendor-driver, the
      command remains stuck forever waiting for destruction of all rdma-cm-id.
      in worst case client can crash during shutdown with active mounts.

      The existing code assumes that ia->ri_id->device cannot change during
      the lifetime of a transport. xprtrdma do not have support for
      DEVICE_REMOVAL event either. Lifting that assumption and adding support
      for DEVICE_REMOVAL event is a long chain of work, and is in plan.

      The community decided that preventing the hang right now is more
      important than waiting for architectural changes.

      Thus, this patch introduces a temporary workaround to acquire HCA driver
      module reference count during the mount of a nfs-rdma mount point.

      xprtrdma: Fix large NFS SYMLINK calls

      Repair how rpcrdma_marshal_req() chooses which RDMA message type
      to use for large non-WRITE operations so that it picks RDMA_NOMSG
      in the correct situations, and sets up the marshaling logic to
      SEND only the RPC/RDMA header.

      Large NFSv2 SYMLINK requests now use RDMA_NOMSG calls. The Linux NFS
      server XDR decoder for NFSv2 SYMLINK does not handle having the
      pathname argument arrive in a separate buffer. The decoder could be
      fixed, but this is simpler and RDMA_NOMSG can be used in a variety
      of other situations.

      Ensure that the Linux client continues to use "RDMA_MSG + read
      list" when sending large NFSv3 SYMLINK requests, which is more
      efficient than using RDMA_NOMSG.

      Large NFSv4 CREATE(NF4LNK) requests are changed to use "RDMA_MSG +
      read list" just like NFSv3 (see Section 5 of RFC 5667). Before,
      these did not work at all.

      xprtrdma: Fix XDR tail buffer marshalling

      Currently xprtrdma appends an extra chunk element to the RPC/RDMA
      read chunk list of each NFSv4 WRITE compound. The extra element
      contains the final GETATTR operation in the compound.

      The result is an extra RDMA READ operation to transfer a very short
      piece of each NFS WRITE compound (typically 16 bytes). This is
      inefficient.

      It is also incorrect.

      The client is sending the trailing GETATTR at the same Position as
      the preceding WRITE data payload. Whether or not RFC 5667 allows
      the GETATTR to appear in a read chunk, RFC 5666 requires that these
      two separate RPC arguments appear at two distinct Positions.

      It can also be argued that the GETATTR operation is not bulk data,
      and therefore RFC 5667 forbids its appearance in a read chunk at
      all.

      Although RFC 5667 is not precise about when using a read list with
      NFSv4 COMPOUND is allowed, the intent is that only data arguments
      not touched by NFS (ie, read and write payloads) are to be sent
      using RDMA READ or WRITE.

      The NFS client constructs GETATTR arguments itself, and therefore is
      required to send the trailing GETATTR operation as additional inline
      content, not as a data payload.

      NB: This change is not backwards compatible. Some older servers do
      not accept inline content following the read list. The Linux NFS
      server should handle this content correctly as of commit
      a97c331f9aa9 ("svcrdma: Handle additional inline content").

      xprtrdma: Don't provide a reply chunk when expecting a short reply

      Currently Linux always offers a reply chunk, even when the reply
      can be sent inline (ie. is smaller than 1KB).

      On the client, registering a memory region can be expensive. A
      server may choose not to use the reply chunk, wasting the cost of
      the registration.

      This is a change only for RPC replies smaller than 1KB which the
      server constructs in the RPC reply send buffer. Because the elements
      of the reply must be XDR encoded, a copy-free data transfer has no
      benefit in this case.

      xprtrdma: Always provide a write list when sending NFS READ

      The client has been setting up a reply chunk for NFS READs that are
      smaller than the inline threshold. This is not efficient: both the
      server and client CPUs have to copy the reply's data payload into
      and out of the memory region that is then transferred via RDMA.

      Using the write list, the data payload is moved by the device and no
      extra data copying is necessary.

      xprtrdma: Account for RPC/RDMA header size when deciding to inline

      When the size of the RPC message is near the inline threshold (1KB),
      the client would allow messages to be sent that were a few bytes too
      large.

      When marshaling RPC/RDMA requests, ensure the combined size of
      RPC/RDMA header and RPC header do not exceed the inline threshold.
      Endpoints typically reject RPC/RDMA messages that exceed the size
      of their receive buffers.

      The two server implementations I test with (Linux and Solaris) use
      receive buffers that are larger than the clientâ??s inline threshold.
      Thus so far this has been benign, observed only by code inspection.

      xprtrdma: Remove logic that constructs RDMA_MSGP type calls

      RDMA_MSGP type calls insert a zero pad in the middle of the RPC
      message to align the RPC request's data payload to the server's
      alignment preferences. A server can then "page flip" the payload
      into place to avoid a data copy in certain circumstances. However:

      1. The client has to have a priori knowledge of the server's
         preferred alignment

      2. Requests eligible for RDMA_MSGP are requests that are small
         enough to have been sent inline, and convey a data payload
         at the _end_ of the RPC message

      Today 1. is done with a sysctl, and is a global setting that is
      copied during mount. Linux does not support CCP to query the
      server's preferences (RFC 5666, Section 6).

      A small-ish NFSv3 WRITE might use RDMA_MSGP, but no NFSv4
      compound fits bullet 2.

      Thus the Linux client currently leaves RDMA_MSGP disabled. The
      Linux server handles RDMA_MSGP, but does not use any special
      page flipping, so it confers no benefit.

      Clean up the marshaling code by removing the logic that constructs
      RDMA_MSGP type calls. This also reduces the maximum send iovec size
      from four to just two elements.

      /proc/sys/sunrpc/rdma_inline_write_padding is a kernel API, and
      thus is left in place.

      xprtrdma: Remove last ib_reg_phys_mr() call site

      All HCA providers have an ib_get_dma_mr() verb. Thus
      rpcrdma_ia_open() will either grab the device's local_dma_key if one
      is available, or it will call ib_get_dma_mr(). If ib_get_dma_mr()
      fails, rpcrdma_ia_open() fails and no transport is created.

      Therefore execution never reaches the ib_reg_phys_mr() call site in
      rpcrdma_register_internal(), so it can be removed.

      The remaining logic in rpcrdma_{de}register_internal() is folded
      into rpcrdma_{alloc,free}_regbuf().

      This is clean up only. No behavior change is expected.

      xprtrdma: Don't fall back to PHYSICAL memory registration

      PHYSICAL memory registration uses a single rkey for all of the
      client's memory, thus is insecure. It is still useful in some cases
      for testing.

      Retain the ability to select PHYSICAL memory registration capability
      via /proc/sys/sunrpc/rdma_memreg_strategy, but don't fall back to it
      if the HCA does not support FRWR or FMR.

      This means amso1100 no longer works out of the box with NFS/RDMA.
      When using amso1100 HCAs, set the memreg_strategy sysctl to 6 before
      performing NFS/RDMA mounts.

      usb: ehci-platform: Fix using multiple controllers from OF

      When using OF defined controllers the platform data struct is shared
      between all devices, so it can't be used for device specific settings.
      However it is currently used for the OF properties
      needs-reset-on-resume and has-transaction-translator.

      To fix this issue move setting hcd->has_tt to the probe and
      move pdata->reset_on_resume to the private data.

      spmi: add command tracepoints for SPMI

      Add tracepoints to retrieve information about read, write
      and non-data commands. For performance measurement support
      tracepoints are added at the beginning and at the end of
      transfers. Following is a list showing the new tracepoint
      events. The "cmd" parameter here represents the opcode, SID,
      and full 16-bit address.

      spmi_write_begin: cmd and data buffer.
      spmi_write_end  : cmd and return value.
      spmi_read_begin : cmd.
      spmi_read_end   : cmd, return value and data buffer.
      spmi_cmd        : cmd.

      The reason that cmd appears at both the beginning and at
      the end event is that SPMI drivers can request commands
      concurrently. cmd helps in matching the corresponding
      events.

      SPMI tracepoints can be enabled like:

      echo 1 >/sys/kernel/debug/tracing/events/spmi/enable

      and will dump messages that can be viewed in
      /sys/kernel/debug/tracing/trace that look like:

      ... spmi_read_begin: opc=56 sid=00 addr=0x0000
      ... spmi_read_end: opc=56 sid=00 addr=0x0000 ret=0 len=02 buf=0x[01-40]
      ... spmi_write_begin: opc=48 sid=00 addr=0x0000 len=3 buf=0x[ff-ff-ff]

      char: xillybus: Allow 64-bit DMA on PCIe interface

      Until now, only 32-bit DMA addressing was allowed, following a report on
      some old Intel machine that dropped 64-bit PCIe packets, even though
      pci_set_dma_mask() was successful with DMA_BIT_MASK(64).

      But then came TI's Keystone II chip (ARM Cortex A15 + DSPs), which refuses
      32-bit DMA addressing (for good reasons). So 64-bit DMA is allowed as a
      fallback option.

      serial: 8250_pci: fix mode after S3/S4 resume for F81504/508/512

      Fix RS232/485 mode incorrect setting after S3/S4 resume for F81504/508/512

      We had add RS232/485 RTS control with fecf27a373f5. But when it
      resume from S3/S4, the mode register 0x40 + 0x08 * idx + 7 will
      rewrite to 0x01 (RS232 mode).

      This patch will modify 2 sections.

      One is pci_fintek_init(), if it called when first init, it will
      write mode register with 0x01. If it called from S3/S4 resume,
      it's will get the relative port data and pass it to
      pci_fintek_rs485_config() with NULL rs485 parameter.

      The another modification is in pci_fintek_rs485_config(). It'll
      re-apply old configuration when the parameter rs485 is NULL.

      staging: unisys: visornic: Convert to using napi

      Switch the visornic over to use napi.  Currently there is a kernel
      thread that sits and waits on a wait queue to get notified of incoming
      virtual interrupts. It would be nice if we could handle frame reception
      using the standard napi processing instead.  This patch creates our napi
      instance and has the rx thread schedule it

      Given that the unisys hypervisor currently requires that queue servicing
      be done by a polling loop that wakes up every 2ms, lets instead also
      convert that to a timer, which is simpler, and allows us to remove all
      the thread starting and stopping code.

      cpu-hotplug: export cpu_hotplug_enable/cpu_hotplug_disable

      Hyper-V module needs to disable cpu hotplug (offlining) as there is no
      support from hypervisor side to reassign already opened event channels
      to a different CPU. Currently it is been done by altering
      smp_ops.cpu_disable but it is hackish.

      cpu-hotplug: convert cpu_hotplug_disabled to a counter

      As a prerequisite to exporting cpu_hotplug_enable/cpu_hotplug_disable
      functions to modules we need to convert cpu_hotplug_disabled to a counter
      to properly support disable -> disable -> enable call sequences. E.g.
      after Hyper-V vmbus module (which is supposed to be the first user of
      exported cpu_hotplug_enable/cpu_hotplug_disable) did cpu_hotplug_disable()
      hibernate path calls disable_nonboot_cpus() and if we hit an error in
      _cpu_down() enable_nonboot_cpus() will be called on the failure path (thus
      making cpu_hotplug_disabled = 0 and leaving cpu hotplug in 'enabled'
      state). Same problem is possible if more than 1 module use
      cpu_hotplug_disable/cpu_hotplug_enable on their load/unload paths. When
      one of these modules is been unloaded it is logical to leave cpu hotplug
      in 'disabled' state.

      To support the change we need to increse cpu_hotplug_disabled counter
      in disable_nonboot_cpus() unconditionally as all users of
      disable_nonboot_cpus() are supposed to do enable_nonboot_cpus() in case
      an error was returned.

      drivers:hv: Modify hv_vmbus to search for all MMIO ranges available.

      This patch changes the logic in hv_vmbus to record all of the ranges in 
the
      VM's firmware (BIOS or UEFI) that offer regions of memory-mapped I/O 
space for
      use by paravirtual front-end drivers.  The old logic just found one range
      above 4GB and called it good.  This logic will find any ranges above 1MB.

      It would have been possible with this patch to just use existing resource
      allocation functions, rather than keep track of the entire set of Hyper-V
      related MMIO regions in VMBus.  This strategy, however, is not sufficient
      when the resource allocator needs to be aware of the constraints of a
      Hyper-V virtual machine, which is what happens in the next patch in the 
series.
      So this first patch exists to show the first steps in reworking the MMIO
      allocation paths for Hyper-V front-end drivers.

      If the device is in idle mode and is in the middle of a scan it may not
      have a chance to react to the reset and then IAP commands within required
      time interval and firmware update may fail. Let's bring the device out of
      idle mode before attempting to reset it so that the scan period is smaller
      and thus it can react to the command quicker.

      With well over 200+ users of this api, there are a mere 12 users that
      actually checked the return value of this function.  And all of them
      really didn't do anything with that information as the system or module

      So stop pretending like it matters, and just return void from
      misc_deregister().  If something goes wrong in the call, you will get a
      WARNING splat in the syslog so you know how to fix up your driver.
      Other than that, there's nothing that can go wrong.

      get_maintainers.pl would list linux-arm-kernel for most bcm2835
      changes because it's under arch/arm, but might not for other bcm2835
      drivers.  Most ARM architectures appear to list linux-arm-kernel as an
      appropriate list as well.

      ARM: dove: create a proper PMU driver for power domains, PMU IRQs and 
resets

      The PMU device contains an interrupt controller, power control and
      resets.  The interrupt controller is a little sub-standard in that
      there is no race free way to clear down pending interrupts, so we try
      to avoid problems by reducing the window as much as possible, and
      clearing as infrequently as possible.

      The interrupt support is implemented using an IRQ domain, and the
      parent interrupt referenced in the standard DT way.

      The power domains and reset support is closely related - there is a
      defined sequence for powering down a domain which is tightly coupled
      with asserting the reset.  Hence, it makes sense to group these two
      together, and in order to avoid any locking contention disrupting this
      sequence, we avoid the use of syscon or regmap.

      This patch adds the core PMU driver: power domains must be defined in
      the DT file in order to make use of them.  The reset controller can
      be referenced in the standard way for reset controllers.

      One usaful case for partial time is to work with per-event callgraph to
      enable "PEBS threshold > 1" (https://lkml.org/lkml/2015/5/10/196), which

      f2fs: invalidate temporary meta page

      To avoid meeting garbage data in next free node block at the end of warm
      node chain when doing recovery, we will try to zero out that invalid 
block.

      If the device is not support discard, our way for zeroing out block is:
      grabbing a temporary zeroed page in meta inode, then, issue write request
      with this page.

      But, we forget to release that temporary page, so our memory usage will
      increase without gaining any hit ratio benefit, so it's better to free it
      for saving memory.

      f2fs: fix to release inode page correctly

      In following call path, we will pass a locked and referenced ipage
      pointer to get_new_data_page:
       - init_inode_metadata
        - make_empty_dir
         - get_new_data_page

      There are two exit paths in get_new_data_page when error occurs:
      1) grab_cache_page fails, ipage will not be released;
      2) f2fs_reserve_block fails, ipage will be released in callee.

      So, it's not consistent for error handling in get_new_data_page.

      For f2fs_reserve_block, it's not very easy to change the rule
      of error handling, since it's already complicated.

      Here we deside to choose an easy way to fix this issue:
      If any error occur in get_new_data_page, we will ensure releasing
      ipage in this function.

      The same issue is in f2fs_convert_inline_dir, fix that too.

      In get_meta_page, we guarantee no failure for the returned page,
      but sometimes, IO error from device will incur returning an
      non-updated page.

      Then, we still use this page as updated one, exception could happen
      when using this kind of page.

      So in this condition, we'd better freeze fs by making fs readonly and

      cache.

      But when traversing all nat pages we readaheaded in a circulation,
      our exit condition is not set right, one more nat page will be scanned
      without readaheading, resulting worse read performance.

      f2fs: add new interfaces for extent tree

      Add a lookup and a insertion interface for extent tree.
      The new lookup return the insert position and the prev/next
      extents closest to the offset we lookup when find no match.
      The new insertion uses above parameters to improve performance.

      There are three possible insertions after the lookup in
      f2fs_update_extent_tree, two of them insert parts of removed extent
      back to tree, since no merge happens during this process, new insertion
      skips the merge check in this scanario; the another insertion inserts a
      new extent to tree, new insertion uses prev/next extent and insert
      position to insert this extent directly, and save the time of searching
      down the tree.

      As long as tree remains unchanged between lookup and insertion, this
      would work fine. And the new lookup would be useful when add
      multi-blocks extent support for insertion interface.

      ALSA: aoa-soundbus: Switch to dev_pm_ops

      Update the aoa-soundbus framework to use dev_pm_ops rather than the
      deprecated legacy suspend and resume callbacks.

      Since there isn't anything special to do at the bus level the bus driver
      does not have to implement any callbacks. The device driver core will
      automatically pick up and execute the device's PM ops.

      As there is only a single aoa-soundbus driver implementing suspend and
      resume, update both the core and driver at the same time to avoid
      unnecessary code churn.

      perf trace: Deref sys_enter pointer args with contents from 
probe:vfs_getname

      To work like strace and dereference syscall pointer args we need to
      insert probes (or tracepoints) right after we copy those bytes from
      userspace.

      Since we're formatting the syscall args at raw_syscalls:sys_enter time,
      we need to have a formatter that just stores the position where, later,
      when we get the probe:vfs_getname, we can insert the pointer contents.

      Now, if a probe:vfs_getname with this format is in place:

       # perf probe -l
        probe:vfs_getname (on getname_flags:72@/home/git/linux/fs/namei.c with 
pathname)

      That was, in this case, put in place with:

       # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
       Added new event:
        probe:vfs_getname    (on getname_flags:72 with pathname=filename:string)

       You can now use it in all perf tools, such as:

        perf record -e probe:vfs_getname -aR sleep 1
       #

      Then 'perf trace' will notice that and do the pointer -> contents
      expansion:

       # trace -e open touch /tmp/bla
        0.165 (0.010 ms): touch/17752 open(filename: /etc/ld.so.cache, flags: 
CLOEXEC) = 3
        0.195 (0.011 ms): touch/17752 open(filename: /lib64/libc.so.6, flags: 
CLOEXEC) = 3
        0.512 (0.012 ms): touch/17752 open(filename: 
/usr/lib/locale/locale-archive, flags: CLOEXEC) = 3
        0.582 (0.012 ms): touch/17752 open(filename: /tmp/bla, flags: 
CREAT|NOCTTY|NONBLOCK|WRONLY, mode: 438) = 3
       #

      Roughly equivalent to strace's output:

       # strace -rT -e open touch /tmp/bla
        0.000000 open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3 <0.000039>
        0.000317 open("/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 <0.000102>
        0.001461 open("/usr/lib/locale/locale-archive", O_RDONLY|O_CLOEXEC) = 3 
<0.000072>
        0.000405 open("/tmp/bla", O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666) = 
3 <0.000055>
        0.000641 +++ exited with 0 +++
       #

      Now we need to either look for at all syscalls that are marked as
      pointers and have some well known names ("filename", "pathname", etc)
      and set the arg formatter to the one used for the "open" syscall in this
      patch.

      This implementation works for syscalls with just a string being copied
      from userspace, for matching syscalls with more than one string being
      copied via the same probe/trace point (vfs_getname) we need to extend
      the vfs_getname probe spec to include the pointer too, but there are
      some problems with that in 'perf probe' or the kernel kprobes code, need
      to investigate before considering supporting multiple strings per
      syscall.

      perf trace: Use a constant for the syscall formatting buffer

      We were using it as a magic number, 1024, fix that.

      Eventually we need to stop doing it per line, and do it per
      arg, traversing the args at output time, to avoid the memmove()
      calls that will be used in the next cset to replace pointers
      present at raw_syscalls:sys_enter time with its contents that
      appear at probe:vfs_getname time, before raw_syscalls:sys_exit
      time.

      ASN.1: Handle 'ANY OPTIONAL' in grammar

      An ANY object in an ASN.1 grammar that is marked OPTIONAL should be 
skipped
      if there is no more data to be had.

      This can be tested by editing X.509 certificates or PKCS#7 messages to
      remove the NULL from subobjects that look like the following:

        SEQUENCE {
          OBJECT(2a864886f70d01010b);
          NULL();
        }

      This is an algorithm identifier plus an optional parameter.

      The modified DER can be passed to one of:

        keyctl padd asymmetric "" @s </tmp/modified.x509
        keyctl padd pkcs7_test foo @s </tmp/modified.pkcs7

      It should work okay with the patch and produce EBADMSG without.

      DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD()
      that it automatically calculates the number of items in the TLV and is
      hence less prone to manual error.

      ASoC: 88pm860x: Replace TLV_DB_RANGE_HEAD with DECLARE_TLV_DB_RANGE

      DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD()

      drm/vmwgfx: Implement fbdev on kms v2

      With screen targets the old legacy display system fbdev doesn't work
      satisfactory anymore. At best the resolution is severely restricted.
      Therefore implement fbdev on top of the kms system. With this change, 
fbdev
      will be using whatever KMS backend is chosen.

      There are helpers available for this, so in the future we'd probably want
      to implement the helper callbacks instead of calling into our KMS
      implementation directly.

      v2: Make sure we take the mode_config mutex around modesetting,
      Also clear the initial framebuffer using vzalloc instead of vmalloc.

      drm/vmwgfx: Add a kernel interface to create a framebuffer v2

      The kernel interface is needed for fbdev, and needs to be free from
      a file_priv member. To accomplish this, remove the fb surface mutex
      and list which isn't used anymore, anyway.

      Finally, make the pin() and unpin() pin the framebuffer for all display
      system backends, so that fbdev can pin its framebuffer before mapping it.

      v2: Address review comments:
      - Fix vmw_framebuffer_unpin() to handle also the surface framebuffer case.
      - Fix vmw_kms_new_framebuffer() to actually use the only_2d parameter.

      drm/vmwgfx: Replace SurfaceDMA usage with SurfaceCopy in 2D VMs

      This patch address the following underlying issues with SurfaceDMA

      * SurfaceDMA command does not work in a 2D VM, but we can wrap a
        proxy surface around the same DMA buffer and use the SurfaceCopy
        command which does work in a 2D VM.

      * Wrapping a DMA buffer with a proxy surface also gives us an
        added optimization path for the case when the DMA buf
        dimensions match the mode.  In this case, the DMA buf can
        be pinned as the display surface, saving an extra copy.
        This only works in a 2D VM because we won't be doing any
        rendering operations directly to the display surface.

      v2
      * Moved is_dmabuf_proxy field to vmw_framebuffer_surface
      * Undone coding style changes
      * Addressed other issues from review

      ASN.1: Fix non-match detection failure on data overrun

      If the ASN.1 decoder is asked to parse a sequence of objects, non-optional
      matches get skipped if there's no more data to be had rather than a
      data-overrun error being reported.

      This is due to the code segment that decides whether to skip optional
      matches (ie. matches that could get ignored because an element is marked
      OPTIONAL in the grammar) due to a lack of data also skips non-optional
      elements if the data pointer has reached the end of the buffer.

      This can be tested with the data decoder for the new RSA akcipher 
algorithm
      that takes three non-optional integers.  Currently, it skips the last
      integer if there is insufficient data.

      Without the fix, #defining DEBUG in asn1_decoder.c will show something
      like:

        next_op: pc=0/13 dp=0/270 C=0 J=0
        - match? 30 30 00
        - TAG: 30 266 CONS
        next_op: pc=2/13 dp=4/270 C=1 J=0
        - match? 02 02 00
        - TAG: 02 257
        - LEAF: 257
        next_op: pc=5/13 dp=265/270 C=1 J=0
        - match? 02 02 00
        - TAG: 02 3
        - LEAF: 3
        next_op: pc=8/13 dp=270/270 C=1 J=0
        next_op: pc=11/13 dp=270/270 C=1 J=0
        - end cons t=4 dp=270 l=270/270

      The next_op line for pc=8/13 should be followed by a match line.

      This is not exploitable for X.509 certificates by means of shortening the
      message and fixing up the ASN.1 CONS tags because:

       (1) The relevant records being built up are cleared before use.

       (2) If the message is shortened sufficiently to remove the public key, 
the
           ASN.1 parse of the RSA key will fail quickly due to a lack of data.

       (3) Extracted signature data is either turned into MPIs (which cope with 
a
           0 length) or is simpler integers specifying algoritms and suchlike
           (which can validly be 0); and

       (4) The AKID and SKID extensions are optional and their removal is 
handled
           without risking passing a NULL to asymmetric_key_generate_id().

       (5) If the certificate is truncated sufficiently to remove the subject,
           issuer or serialNumber then the ASN.1 decoder will fail with a 'Cons
           stack underflow' return.

      This is not exploitable for PKCS#7 messages by means of removal of 
elements
      from such a message from the tail end of a sequence:

       (1) Any shortened X.509 certs embedded in the PKCS#7 message are 
survivable
           as detailed above.

       (2) The message digest content isn't used if it shows a NULL pointer,
           similarly, the authattrs aren't used if that shows a NULL pointer.

       (3) A missing signature results in a NULL MPI - which the MPI routines 
deal
           with.

       (4) If data is NULL, it is expected that the message has detached 
content and
           that is handled appropriately.

       (5) If the serialNumber is excised, the unconditional action associated
           with it will pick up the containing SEQUENCE instead, so no NULL
           pointer will be seen here.

           If both the issuer and the serialNumber are excised, the ASN.1 decode
           will fail with an 'Unexpected tag' return.

           In either case, there's no way to get to asymmetric_key_generate_id()
           with a NULL pointer.

       (6) Other fields are decoded to simple integers.  Shortening the message
           to omit an algorithm ID field will cause checks on this to fail early
           in the verification process.


      This can also be tested by snipping objects off of the end of the ASN.1 
stream
      such that mandatory tags are removed - or even from the end of internal
      SEQUENCEs.  If any mandatory tag is missing, the error EBADMSG *should* be
      produced.  Without this patch ERANGE or ENOPKG might be produced or the 
parse
      may apparently succeed, perhaps with ENOKEY or EKEYREJECTED being produced
      later, depending on what gets snipped.

      Just snipping off the final BIT_STRING or OCTET_STRING from either sample
      should be a start since both are mandatory and neither will cause an 
EBADMSG
      without the patches

      ASN.1: Fix actions on CHOICE elements with IMPLICIT tags

      In an ASN.1 description where there is a CHOICE construct that contains
      elements with IMPLICIT tags that refer to constructed types, actions to be
      taken on those elements should be conditional on the corresponding element
      actually being matched.  Currently, however, such actions are performed
      unconditionally in the middle of processing the CHOICE.

      For example, look at elements 'b' and 'e' here:

        A ::= SEQUENCE {
                        CHOICE {
                        b [0] IMPLICIT B ({ do_XXXXXXXXXXXX_b }),
                        c [1] EXPLICIT C ({ do_XXXXXXXXXXXX_c }),
                        d [2] EXPLICIT B ({ do_XXXXXXXXXXXX_d }),
                        e [3] IMPLICIT C ({ do_XXXXXXXXXXXX_e }),
                        f [4] IMPLICIT INTEGER ({ do_XXXXXXXXXXXX_f })
                        }
                } ({ do_XXXXXXXXXXXX_A })

        B ::= SET OF OBJECT IDENTIFIER ({ do_XXXXXXXXXXXX_oid })

        C ::= SET OF INTEGER ({ do_XXXXXXXXXXXX_int })

      They each have an action (do_XXXXXXXXXXXX_b and do_XXXXXXXXXXXX_e) that
      should only be processed if that element is matched.

      The problem is that there's no easy place to hang the action off in the
      subclause (type B for element 'b' and type C for element 'e') because
      subclause opcode sequences can be shared.

      To fix this, introduce a conditional action opcode(ASN1_OP_MAYBE_ACT) that
      the decoder only processes if the preceding match was successful.  This 
can
      be seen in an excerpt from the output of the fixed ASN.1 compiler for the
      above ASN.1 description:

        [  13] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // e
        [  14] =  _tagn(CONT, CONS,  3),
        [  15] =  _jump_target(45),             // --> C
        [  16] =  ASN1_OP_MAYBE_ACT,
        [  17] =  _action(ACT_do_XXXXXXXXXXXX_e),

      In this, if the op at [13] is matched (ie. element 'e' above) then the
      action at [16] will be performed.  However, if the op at [13] doesn't 
match
      or is skipped because it is conditional and some previous op matched, then
      the action at [16] will be ignored.

      Note that to make this work in the decoder, the ASN1_OP_RETURN op must set
      the flag to indicate that a match happened.  This is necessary because the
      _jump_target() seen above introduces a subclause (in this case an object 
of
      type 'C') which is likely to alter the flag.  Setting the flag here is 
okay
      because to process a subclause, a match must have happened and caused a
      jump.

      This cannot be tested with the code as it stands, but rather affects 
future
      code.

      ASN.1: Fix handling of CHOICE in ASN.1 compiler

      Fix the handling of CHOICE types in the ASN.1 compiler to make SEQUENCE 
and
      SET elements in a CHOICE be correctly rendered as skippable and 
conditional
      as appropriate.

      For example, in the following ASN.1:

        Foo ::= SEQUENCE { w1 INTEGER, w2 Bar, w3 OBJECT IDENTIFIER }
        Bar ::= CHOICE {
                x1 Seq1,
                x2 [0] IMPLICIT OCTET STRING,
                x3 Seq2,
                x4 SET OF INTEGER
        }
        Seq1 ::= SEQUENCE { y1 INTEGER, y2 INTEGER, y3 INTEGER }
        Seq2 ::= SEQUENCE { z1 BOOLEAN, z2 BOOLEAN, z3 BOOLEAN }

      the output in foo.c generated by:

        ./scripts/asn1_compiler foo.asn1 foo.c foo.h

      included:

        // Bar
        // Seq1
        [   4] =  ASN1_OP_MATCH,
        [   5] =  _tag(UNIV, CONS, SEQ),
        ...
        [  13] =  ASN1_OP_COND_MATCH_OR_SKIP,           // x2
        [  14] =  _tagn(CONT, PRIM,  0),
        // Seq2
        [  15] =  ASN1_OP_MATCH,
        [  16] =  _tag(UNIV, CONS, SEQ),
        ...
        [  24] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // x4
        [  25] =  _tag(UNIV, CONS, SET),
        ...
        [  27] =  ASN1_OP_COND_FAIL,

      as a result of the CHOICE - but this is wrong on lines 4 and 15 because
      both of these should be skippable (one and only one of the four can be
      picked) and the one on line 15 should also be conditional so that it is
      ignored if anything before it matches.

      After the patch, it looks like:

        // Bar
        // Seq1
        [   4] =  ASN1_OP_MATCH_JUMP_OR_SKIP,           // x1
        [   5] =  _tag(UNIV, CONS, SEQ),
        ...
        [   7] =  ASN1_OP_COND_MATCH_OR_SKIP,           // x2
        [   8] =  _tagn(CONT, PRIM,  0),
        // Seq2
        [   9] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // x3
        [  10] =  _tag(UNIV, CONS, SEQ),
        ...
        [  12] =  ASN1_OP_COND_MATCH_JUMP_OR_SKIP,              // x4
        [  13] =  _tag(UNIV, CONS, SET),
        ...
        [  15] =  ASN1_OP_COND_FAIL,

      where all four options are skippable and the second, third and fourth are
      all conditional, as is the backstop at the end.

      This hasn't been a problem so far because in the ASN.1 specs we have are
      either using primitives or are using SET OF and SEQUENCE OF which are
      handled correctly.

      Whilst we're at it, also make sure that element labels get included in
      comments in the output for elements that have complex types.

      This cannot be tested with the code as it stands, but rather affects 
future
      code.

      KVM: MMU: fix validation of mmio page fault

      We got the bug that qemu complained with "KVM: unknown exit, hardware
      reason 31" and KVM shown these info:
      [84245.284948] EPT: Misconfiguration.
      [84245.285056] EPT: GPA: 0xfeda848
      [84245.285154] ept_misconfig_inspect_spte: spte 0x5eaef50107 level 4
      [84245.285344] ept_misconfig_inspect_spte: spte 0x5f5fadc107 level 3
      [84245.285532] ept_misconfig_inspect_spte: spte 0x5141d18107 level 2
      [84245.285723] ept_misconfig_inspect_spte: spte 0x52e40dad77 level 1

      This is because we got a mmio #PF and the handler see the mmio spte 
becomes
      normal (points to the ram page)

      However, this is valid after introducing fast mmio spte invalidation which
      increases the generation-number instead of zapping mmio sptes, a example
      is as follows:
      1. QEMU drops mmio region by adding a new memslot
      2. invalidate all mmio sptes
      3.

              VCPU 0                        VCPU 1
          access the invalid mmio spte
                                  access the region originally was MMIO before
                                  set the spte to the normal ram map

          mmio #PF
          check the spte and see it becomes normal ram mapping !!!

      This patch fixes the bug just by dropping the check in mmio handler, it's
      good for backport. Full check will be introduced in later patches

      So change the BUG_ON into a gen check (alternately we could move the

      toshiba_acpi: Refactor *{get, set} functions return value

      This patch refactors the return value of the driver *{get, set}
      functions, since the driver default error value is -EIO.

      All the functions now check for TOS_FAILURE, TOS_NOT_SUPPORTED and
      TOS_SUCCESS.

      On TOS_FAILURE a pr_err message is printed informing the user of the
      error (no change was made to this, except the check was added to the
      functions not checking for this).

      On TOS_NOT_SUPPORTED we now return -ENODEV immediately (some
      functions were returning -EIO and some other were not checking)

      On TOS_SUCCESS* we now return 0 (as a side effect, a new success value
      was added, since some functions return one instead of zero to
      indicate success).

      As a special case, the LED functions now check for *FAILURE on
      *set, and check for TOS_FAILURE and TOS_SUCCESS on *get with their
      "default" return value set to LED_OFF.

      Also the {lcd, video}_proc* functions were adapted to reflect these
      changes to their parent HCI functions.

      This patch changes the *available functions return type from int to
      void.

      The checks for support of their respective features are done inside
      such functions and there was no need to return anything as we can
      flag the queried feature as supported inside these functions.

      The code was adapted accordingly to these changes and two new
      variables were created and another was changed from uint to bool.

      Also, the function toshiba_acceleremoter_supported was renamed to
      toshiba_accelerometer_available to maintain the naming consistency on
      the driver.

      arm64: mm: ensure patched kernel text is fetched from PoU

      The arm64 booting document requires that the bootloader has cleaned the
      kernel image to the PoC. However, when a CPU re-enters the kernel due to
      either a CPU hotplug "on" event or resuming from a low-power state (e.g.
      cpuidle), the kernel text may in-fact be dirty at the PoU due to things
      like alternative patching or even module loading.

      Thanks to I-cache speculation with the MMU off, stale instructions could
      be fetched prior to enabling the MMU, potentially leading to crashes
      when executing regions of code that have been modified at runtime.

      This patch addresses the issue by ensuring that the local I-cache is
      invalidated immediately after a CPU has enabled its MMU but before
      jumping out of the identity mapping. Any stale instructions fetched from
      the PoC will then be discarded and refetched correctly from the PoU.
      Patching kernel text executed prior to the MMU being enabled is
      prohibited, so the early entry code will always be clean.

      drm/i915/gen9: Removed byte swapping for csr firmware

      This patch contains the changes to remove the byte
      swapping logic introduced with old dmc firmware.
      While debugging PC10 entry issue for skylake found
      with latest dmc firmware version 1.18 without byte
      swapping dmc is working fine and able to enter PC10.

      Note that apparently this was changed with dmc version 1.0 and earlier
      ones indeed are byteswapped like this ...

      v1: Initial version.

      v2: Corrected firmware size during memcpy(). (Suggested by Sunil)

      x86/entry/32: Remove 32-bit syscall audit optimizations

      The asm audit optimizations are ugly and obfuscate the code too
      much. Remove them.

      This will regress performance if syscall auditing is enabled on
      32-bit kernels and SYSENTER is in use. If this becomes a
      problem, interested parties are encouraged to implement the
      equivalent of the 64-bit opportunistic SYSRET optimization.

      Alternatively, a case could be made that, on 32-bit kernels, a
      less messy asm audit optimization could be done. 32-bit kernels
      don't have the complicated partial register saving tricks that
      64-bit kernels have, so the SYSENTER post-syscall path could
      just call the audit hooks directly.  Any reimplementation of
      this ought to demonstrate that it only calls the audit hook once
      per syscall, though, which does not currently appear to be true.

      Someone would have to make the case that doing so would be
      better than implementing opportunistic SYSEXIT, though.

saving
      feature for idle scenario. So if it is idle feature stays on and 500ms to 
get
      it reanabled is not that insane.

      v2: Rebase over intel_psr.c and fix typo.
      v3: Revival: Manual tests indicated that this is needed. With a short 
delay
          there is a huge risk of getting blank screens when planes are being 
enabled.
      v4: Revival 2 with reasonable delay. 1/2 sec instead of 5. VBT is 10 sec 
but
          actually time for link training what we aren't doing, but with only 
100 sec
          in some cases kms_psr_sink_crc manual was showing blank screen,
          so let's use this for now. Also changed comment by a FIXME.
      v5: Rebase after a long time, remove FIXME and update comment above.
      v6: msecs_to_jiffies is already on delay. remove duplication.
      v7: use msecs_to_jiffies on schedule_delayed_work call.

      drm/i915: Split sink_crc function in start, stop and read.

      This is just a preparation patch to make clear what operation we
      are performing. There is no functional change on the sink crc
      logic.

      hsw_disable_ips has been moved a bit further in the start function
      to avoid disabling ips when sink crc is not going to be started.
      and to avoid goto on this function.

      v2: explain why hsw_disable_ips() call place has changed.

      drm/i915: special-case dirtyfb for frontbuffer tracking

      First, an introduction. We currently have two types of GTT mmaps: the
      "normal" old mmap, and the WC mmap. For frontbuffer-related features
      that have automatic hardware tracking, only the non-WC mmap writes are
      detected by the hardware. Since inside the Kernel both are treated as
      ORIGIN_GTT, any features ignoring ORIGIN_GTT because of the hardware
      tracking are destined to fail.

      One of the special rules defined for the WC mmaps is that the user
      should call the dirtyfb IOCTL after he is done using the pointers, so
      that results in an intel_fb_obj_flush() call. The problem is that the
      dirtyfb is passing ORIGIN_GTT, so it is being ignored by FBC - even
      though the hardware tracking is not detecing the WC mmap operations.
      So in order to fix that without having to give up the automatic
      hardware tracking for GTT mmaps we transform the flush operation from
      dirtyfb into a special operation: ORIGIN_DIRTYFB.

      This commit fixes all the kms_frontbuffer_tracking subtests that
      contain "fbc" and "mmap-wc" in their names and are currently failing
      (for a total of 16 subtests).

      drm/i915: don't disable FBC for pipe A when flipping pipe B

      Use the appropriate call.

      I know there's a discussion about whether we need this call here at
      all, but removing the call means we'll only update FBC after we get
      the page flip IRQ. So the user may only see the new frame a little
      after it should. Let's wait just a little bit more before removing
      this call since we can rely in the HW tracking for accurate flips.

      drm/i915: don't call intel_fbc_update() at intel_unpin_work_fn()

      Because intel_unpin_work_fn() already calls
      intel_frontbuffer_flip_complete() which will call intel_fbc_flush()
      which will call intel_fbc_update() when needed.

      We couldn't fix this previously due to the fact that FBC was not
      properly behaving as intended on frontbuffer flushes, but now that
      this is fixed, we can remove the additional call.

      drm/i915: fix FBC frontbuffer tracking flushing code

      Due to the way busy_bits was handled, we were not doing any flushes if
      we didn't previously get an invalidate. Since it's possible to get
      flushes without an invalidate first, remove the busy_bits early
      return.

      So now that we don't have the busy_bits guard anymore we'll need the
      origin check for the GTT tracking (we were not doing anything on GTT
      flushes due to the GTT check at invalidate()).

      As a last detail, since we can get multiple consecutive flushes,
      disable FBC before updating it, otherwise intel_fbc_update() will just
      keep FBC enabled instead of restarting it.

      Notice that this does not fix any of the current IGT tests due to the
      fact that we still have a few intel_fbc() calls at points where we
      also have the frontbuffer tracking calls: we didn't fully convert to
      frontbuffer tracking yet. Once we remove those calls and start relying
      only on the frontbuffer tracking infrastructure we'll need this patch.

      ====================
      Netfilter updates for net-next

      The following patchset contains Netfilter updates for net-next, they are:

      1) A couple of cleanups for the netfilter core hook from Eric Biederman.

      2) Net namespace hook registration, also from Eric. This adds a 
dependency with
         the rtnl_lock. This should be fine by now but we have to keep an eye 
on this
         because if we ever get the per-subsys nfnl_lock before rtnl we have may
         problems in the future. But we have room to remove this in the future 
by
         propagating the complexity to the clients, by registering hooks for 
the init
         netns functions.

      3) Update nf_tables to use the new net namespace hook infrastructure, 
also from
         Eric.

      4) Three patches to refine and to address problems from the new net 
namespace
         hook infrastructure.

      5) Switch to alternate jumpstack in xtables iff the packet is reentering. 
This
         only applies to a very special case, the TEE target, but Eric Dumazet
         reports that this is slowing down things for everyone else. So let's 
only
         switch to the alternate jumpstack if the tee target is in used through 
a
         static key. This batch also comes with offline precalculation of the
         jumpstack based on the callchain depth. From Florian Westphal.

      6) Minimal SCTP multihoming support for our conntrack helper, from Michal
         Kubecek.

      7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from 
Florian
         Westphal.

      8) Fix several checkpatch errors in bridge netfilter, from Bernhard 
Thaler.

      9) Get rid of useless debug message in ip6t_REJECT, from Subash Abhinov.

      mshyperv: fix recognition of Hyper-V guest crash MSR's

      Hypervisor Top Level Functional Specification v3.1/4.0 notes that cpuid
      (0x40000003) EDX's 10th bit should be used to check that Hyper-V guest
      crash MSR's functionality available.

      This patch should fix this recognition. Currently the code checks EAX
      register instead of EDX.

      Drivers: hv: vmbus: prefer 'die' notification chain to 'panic'

      current_pt_regs() sometimes returns regs of the userspace process and in
      case of a kernel crash this is not what we need to report. E.g. when we
      trigger crash with sysrq we see the following:
      ...
       RIP: 0010:[<ffffffff815b8696>]  [<ffffffff815b8696>] 
sysrq_handle_crash+0x16/0x20
       RSP: 0018:ffff8800db0a7d88  EFLAGS: 00010246
       RAX: 000000000000000f RBX: ffffffff820a0660 RCX: 0000000000000000
      ...
      at the same time current_pt_regs() give us:
      ip=7f899ea7e9e0, ax=ffffffffffffffda, bx=26c81a0, cx=7f899ea7e9e0, ...
      These registers come from the userspace process triggered the crash. As we
      don't even know which process it was this information is rather useless.

      When kernel crash happens through 'die' proper regs are being passed to
      all receivers on the die_chain (and panic_notifier_list is being notified
      with the string passed to panic() only). If panic() is called manually
      (e.g. on BUG()) we won't get 'die' notification so keep the 'panic'
      notification reporter as well but guard against double reporting.

can
      try to post a message or signal an event. This will crash the kernel as we

      Drivers: hv: vmbus: add special kexec handler

      When general-purpose kexec (not kdump) is being performed in Hyper-V guest
      the newly booted kernel fails with an MCE error coming from the host. It
      is the same error which was fixed in the "Drivers: hv: vmbus: Implement
      the protocol for tearing down vmbus state" commit - monitor pages remain
      special and when they're being written to (as the new kernel doesn't know
      these pages are special) bad things happen. We need to perform some
      minimalistic cleanup before booting a new kernel on kexec. To do so we
      need to register a special machine_ops.shutdown handler to be executed
      before the native_machine_shutdown(). Registering a shutdown notification
      handler via the register_reboot_notifier() call is not sufficient as it
      happens to early for our purposes. machine_ops is not being exported to
      modules (and I don't think we want to export it) so let's do this in
      mshyperv.c

      The minimalistic cleanup consists of cleaning up clockevents, synic MSRs,
      guest os id MSR, and hypercall MSR.

      Kdump doesn't require all this stuff as it lives in a separate memory
      space.

      dmaengine: Add an enum for the dmaengine alignment constraints

      Most drivers need to set constraints on the buffer alignment for async tx
      operations. However, even though it is documented, some drivers either use
      a defined constant that is not matching what the alignment variable 
expects
      (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of
      power of two.

      Add a new enum for these alignments that matches what the framework
      expects, and convert the drivers to it.

      serial: samsung: fix DMA for FIFO smaller than cache line size

      So far DMA mode were activated when only number of bytes to send was
      equal or greater than min_dma_size. Due to requirement that DMA 
transaction
      buffer should be aligned to cache line size, the excessive bytes were
      written to FIFO before starting DMA transaction. The problem occurred
      when FIFO size were smaller than cache alignment, because writing all
      excessive bytes to FIFO would fail. It happened in DMA mode when PIO
      interrupts disabled, which caused driver hung.

      The solution is to test if buffer is alligned to cache line size before
      activating DMA mode, and if it's not, running PIO mode to align buffer
      and then starting DMA transaction. In PIO mode, when interrupts are
      enabled, lack of space in FIFO isn't the problem, so buffer aligning
      will always finish with success.

      twl4030_charger: Increase current carefully while watching voltage.

      The USB Battery Charging spec (BC1.2) suggests a dedicated
      charging port can deliver from 0.5 to 5.0A at between 4.75 and 5.25
      volts.

      To choose the "correct" current voltage setting requires a trial
      and error approach: try to draw current and see if the voltage drops
      too low.

      Even with a configured Standard Downstream Port, it may not be possible
      to reliably pull 500mA - depending on cable quality and source
      quality I have reports of charging failure due to the voltage dropping
      too low.

      To address both these concerns, this patch introduce incremental
      current setting.
      The current pull from VBUS is increased in steps of 20mA every 100ms
      until the target is reached or until the measure voltage drops below
      4.75V.  If the voltage does go too low, the target current is reduced
      by 20mA and kept there.

      This applies to currents selected automatically, or to values
      set via sysfs.  So setting a large value will cause the maximum
      available to be used - up to the limit of 1.7A imposed by the
      hardware.

      Linear charging does a good job with not-so-reliable power sources.

      It was used with a bike hub dynamo since a year or so. In that case

      twl4030_charger: distinguish between USB current and 'AC' current

      The twl4030 charger has two current sources, 'USB' and 'AC'
      (presumably "Accessory Charger" because it isn't Alternating Current).

      If 'AC' is providing current, we should set the current limit
      differently to when it isn't (and so USB is used).
      So split 'cur' into 'usb_cur' and 'ac_cur' and use accordingly.

      Now we must review the current setting on any interrupt or USB
      event which might indicate that the charger-source has changed.

      dmaengine: shdma: Make dummy shdma_chan_filter() always return false

      If CONFIG_SH_DMAE_BASE (which is required for DMA engine support for
      legacy SH, SH/R-Mobile, and R-Car Gen1, but not for R-Car Gen2) is not
      enabled, but CONFIG_RCAR_DMAC (for R-Car Gen2 DMA engine support) is,
      and the DTS doesn't provide a "dmas" property for a device,
      dma_request_slave_channel_compat() incorrectly succeeds, and returns a
      DMA channel.

      However, when trying to use that DMA channel later, it fails with:

          rcar-dmac e6700000.dma-controller: rcar_dmac_prep_slave_sg: bad 
parameter: len=1, id=-22

      (Fortunately most drivers can handle this failure, and fall back to
      PIO)

      The reason for this is that a NULL legacy filter function is used, which
      actually means "all channels are OK", not "do not match".
      If CONFIG_SH_DMAE_BASE is enabled (like in shmobile_defconfig, which
      supports other SoCs besides R-Car Gen2), shdma_chan_filter() correctly
      returns false, as no available channel on R-Car Gen2 matches a
      shdma-base channel.
      If the DTS does provide a "dmas" property, dma_request_slave_channel()
      succeeds, and legacy filter-based matching is not used.

      To fix this, change shdma_chan_filter from being NULL to a dummy
      function that always returns false, like is done on other platforms.

      twl4030_charger: allow fine control of charger current.

      The twl4030 allows control of the incoming current.
      Part of this control is a 'CGAIN' setting which doubles
      the range for half the precision.  This control affects
      several different current setting, so all need to be updated
      at once when CGAIN is changed.

      With this patch, all of these current setting are managed
      by the driver, but most are left at their default settings.

      The current drawn is set to 500mA if the allow_usb module parameter is
      set, and to 100mA otherwise.
      More fine control will appear in later patches.

      phy-twl4030-usb, we can simply take a runtime_pm reference to the USB
      phy whenever the charger wants to use it as a current source.

      So this patch reverts the above commit, and adds the necessary
      runtime_pm calls.

      It also flags to Android using INPUT_PROP_DIRECT that the device should be

      Input: atmel_mxt_ts - use deep sleep mode when stopped

      The hardcoded 0x83 CTRL setting overrides other settings in that byte,
      enabling extra reporting that may not be useful on a particular platform.

      Implement improved suspend mechanism via deep sleep. By writing zero to
      both the active and idle cycle times the maXTouch device can be put into a
      deep sleep mode, using minimal power. It is necessary to issue a calibrate
      command after the chip has spent any time in deep sleep, however a soft
      reset is unnecessary.

      Use the old method on Chromebook Pixel via platform data option.

      This patch also deals with the situation where the power configuration is
      zero on probe, which would mean that the device never wakes up to execute
      commands.

      After a config download, the T7 power configuration may have changed so it
      is necessary to re-read it.

      audit: eliminate unnecessary extra layer of watch parent references

      The audit watch parent count was imbalanced, adding an unnecessary layer 
of
      watch parent references.  Decrement the additional parent reference when a
      watch is reused, already having a reference to the parent.

      audit_find_parent() gets a reference to the parent, if the parent is
      already known.  This additional parental reference is not needed if the
      watch is subsequently found by audit_add_to_parent(), and consumed if
      the watch does not already exist, so we need to put the parent if the
      watch is found, and do nothing if this new watch is added to the parent.

      If the parent wasn't already known, it is created with a refcount of 1
      and added to the audit_watch_group, then incremented by one to be
      subsequently consumed by the newly created watch in
      audit_add_to_parent().

      The rule points to the watch, not to the parent, so the rule's refcount
      gets bumped, not the parent's.

      ARM: shmobile: sh73a0 dtsi: Add missing "gpio-ranges" to gpio node

      If a GPIO driver uses gpiochip_add_pin_range() (which is usually the
      case for GPIO/PFC combos), the GPIO hogging mechanism configured from DT
      doesn't work:

          requesting hog GPIO led1-high (chip sh73a0_pfc, offset 20) failed

      The actual error code is -517 == -EPROBE_DEFER.

      The problem is that PFC+GPIO registration is handled in multiple steps:
        1. pinctrl_register(),
        2. gpiochip_add(),
        3. gpiochip_add_pin_range().

      Configuration of the hogs is handled in gpiochip_add():

          gpiochip_add
              of_gpiochip_add
                  of_gpiochip_scan_hogs
                      gpiod_hog
                          gpiochip_request_own_desc
                              __gpiod_request
                                  chip->request
                                      pinctrl_request_gpio
                                          pinctrl_get_device_gpio_range

      However, at this point the GPIO controller hasn't been added to
      pinctrldev_list yet, so the range can't be found, and the operation fails
      with -EPROBE_DEFER.

      To fix this, add a "gpio-ranges" property to the gpio device node, so
      the ranges are added by of_gpiochip_add_pin_range(), which is called by
      of_gpiochip_add() before the call to of_gpiochip_scan_hogs().

      f2fs: expose f2fs_write_cache_pages

      If there are gced dirty pages and normal dirty pages in the mapping
      of one inode, we might writeback them alternately with discontinuous
      block address, resulting in low performance.

      This patch introduces f2fs_write_cache_pages with codes copied from
      write_cache_pages in mm/page-writeback.c.

      In this function, we refactor flow with two steps:
      1) writeback all cold type pages.
      2) writeback all non-cold type pages.

      By using this method, f2fs will writeback dirty pages with the same
      temperature in bunch mode, it makes writeouted block being with
      more continuous address, so they can be merged as much as possible
      in f2fs bio cache, and also it will reduce the chance of submiting
      small IO from block layer.

      Test environment: 8g nokia sd card (very old sd card, but it shows
      better effect when testing with this patch, and with a 32g kingston
      sd card, I didn't see much more improvement).

      Test step:
      1. touch testfile;
      2. truncate -s 512K testfile;
      3. write all pages with odd index;
      4. trigger gc by ioctl;
      5. write all pages with even index;
      6. time fsync testfile.

      f2fs: cleanup write_orphan_inodes

      Previously, since 'commit 4531929e3922 ("f2fs: move grabing orphan
      pages out of protection region")' was committed, in write_orphan_inodes(),
      we will grab all meta page in a batch before we use them under spinlock,
      so that we can avoid large time delay of grabbing meta pages under
      spinlock.

      Now, 'commit d6c67a4fee86 ("f2fs: revmove spin_lock for
      write_orphan_inodes")' remove the spinlock in write_orphan_inodes,
      so there is no issue we describe above, we'd better recover to move
      the grab operation to original place for readability.

      f2fs: warm up cold page after mmaped write

      With cost-benifit method, background gc will consider old section with
      fewer valid blocks as candidate victim, these old blocks in section will
      be treated as cold data, and laterly will be moved into cold segment.

      But if the gcing page is attached by user through buffered or mmaped
      write, we should reset the page as non-cold one, because this page may
      have more opportunity for further updating.

      So fix to add clearing code for the missed 'mmap' case.

      f2fs: add new ioctl F2FS_IOC_GARBAGE_COLLECT

      When background gc is off, the only way to trigger gc is executing
      a force gc in some operations who wants to grab space in disk.

      The executing condition is limited: to execute force gc, we should
      wait for the time when there is almost no more free section for LFS
      allocation. This seems not reasonable for our user who wants to
      control triggering gc by himself.

      This patch introduces F2FS_IOC_GARBAGE_COLLECT interface for
      triggering garbage collection by using ioctl. It provides our users
      one more option to trigger gc.

      f2fs: maintain extent cache in separated file

      This patch moves extent cache related code from data.c into extent_cache.c
      since extent cache is independent feature, and its codes are not relate to
      others in data.c, it's better for us to maintain them in separated place.

      There is no functionality change, but several small coding style fixes
      including:
      * rename __drop_largest_extent to f2fs_drop_largest_extent for exporting;
      * rename misspelled word 'untill' to 'until';
      * remove unneeded 'return' in the end of f2fs_destroy_extent_tree().

      f2fs: enhance multithread performance

      In ->writepages, we use writepages mutex lock to serialize all block
      address allocation and page submitting pairs from different inodes.
      This method makes our delayed dirty pages of one inode being written
      continously as many as possible.

      But there is one problem that we did not submit current cached bio in
      protection region of writepages mutex lock, so there is a small chance
      that we submit the one of other thread's as below, resulting in
      splitting more bios.

      thread 1                  thread 2
      ->writepages
        lock(writepages)
        ->write_cache_pages
        unlock(writepages)
                                  lock(writepages)
                                  ->write_cache_pages

      This may really increase time of block layer works, and may cause
      larger IO lantency.

      This patch moves the submitting operation into region of writepages
      mutex lock to avoid bio splits when concurrently writebacking is

      f2fs: restrict multimedia filename

      When testing with fs_mark, some blocks were written out as cold
      data which were mixed with warm data, resulting in splitting more
      bios.

      This is because fs_mark will create file with random filename as
      below:

      559551ee~~~~~~~~15Z29OCC05JCKQP60JQ42MKV
      559551ee~~~~~~~~NZAZ6X8OA8LHIIP6XD0L58RM

      559551f3~~~~~~~~8Y2NRK7CEPPAA02LY936PJPG

      They are regarded as cold file since their filename are ended with
      multimedia files' extension, but this should be wrong as we only
      match the extension of filename, not the whole one.

      In this patch, we try to fix the format of multimedia filename to:
      "filename + '.' + extension", then we set cold file only its
      filename matches the format.

      So after this change, it will reduce the probability we set the
      wrong cold file, also it helps a little for fs_mark's performance
      on f2fs.

      cgroup: define controller file conventions

      Traditionally, each cgroup controller implemented whatever interface
      it wanted leading to interfaces which are widely inconsistent.
      Examining the requirements of the controllers readily yield that there
      are only a few control schemes shared among all.

      Two major controllers already had to implement new interface for the
      unified hierarchy due to significant structural changes.  Let's take
      the chance to establish common conventions throughout all controllers.

      This patch defines CGROUP_WEIGHT_MIN/DFL/MAX to be used on all weight
      based control knobs and documents the conventions that controllers
      should follow on the unified hierarchy.  Except for io.weight knob,
      all existing unified hierarchy knobs are already compliant.  A
      follow-up patch will update io.weight.

      v2: Added descriptions of min, low and high knobs.

      iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO

      Family 8000 products has 2 embedded processors, the first
      known as LMAC (lower MAC) and implements the functionality from
      previous products, the second one is known as UMAC (upper MAC)
      and is used mainly for driver offloads as well as new features.
      The UMAC is typically â??lessâ?? real-time than the LMAC and is used
      for higher level controls.
      The UMAC's code/data size is estimated to be in the mega-byte arena,
      taking into account the code it needs to replace in the driver and
      the set of new features.

      In order to allow the UMAC to execute code that is bigger than its code
      memory, we allow the UMAC embedded processor to page out code pages on
      DRAM.

      When the device is slave on the bus(SDIO) the driver saves the UMAC's
      image pages in blocks of 32K in the DRAM and sends the layout of the
      pages to the FW. When the FW wants load / unload pages, it creates an
      interrupt,        and the driver uploads / downloads the page to an 
address in
      the a specific address on the device's memory.

      The driver can support up to 1 MB of pages.

      Add paging mechanism for the UMAC on SDIO in order to allow the program to
      use a larger virtual space while using less physical memory on the device
      itself.

      iwlwifi: pcie: New RBD allocation model

      As a preperation for multiple RX queues change the RBD
      allocation model.

      The new model includes a background allocator. The allocator is
      called by the interrupt handler when there are two released
      buffers by the queue, and the allocator starts allocating eight
      pages per request.
      When the queue has released 8 pages it tries claiming the
      request. If the pages are not ready - it keeps claiming.
      This new model should make sure that RBDs are always available
      across the multiple queues.

      The RBDs are transferred between the allocator and the queue.
      The queue moves the free RBDs upon freeing them to the allocator.
      The allocator moves them back to the queue's possession when the
      request is claimed.
      The allocator has an initial pool to make sure there are always RBDs
      available for the request completion.
      Release of the buffers at exit is done per pools - the allocator
      frees its own initial pool and the queue frees its own pool.

      Existing code refactor -
      -Queue's initial pool is the size of the queue only as the allocation
      of the new buffers no longer uses this pool.
      -Removal of replenish background work, and replenish calls in the
      interrupt handler and restock().
      -The replenish() and the rxq used_list are used only during
      initialization.
      -Moved page allocation to a new function for code reuse.

      New code -
      Allocator code - new structure and functions.
      Interrupt handler uses the allocator functions for replenishing buffers.
      Reuse of the restock() method.

      usb: gadget: add endpoint capabilities flags

      Introduce struct usb_ep_caps which contains information about capabilities
      of usb endpoints - supported transfer types and directions. This structure
      should be filled by UDC driver for each of its endpoints, and will be
      used in epautoconf in new ep matching mechanism which will replace ugly
      guessing of endpoint capabilities basing on its name.

      usb: gadget: encapsulate endpoint claiming mechanism

      So far it was necessary for usb functions to set ep->driver_data in
      endpoint obtained from autoconfig to non-null value, to indicate that
      endpoint is claimed by function (in autoconfig it was checked if endpoint
      has set this field to non-null value, and if it has, it was assumed that
      it is claimed). It could cause bugs because if some function doesn't
      set this field autoconfig could return the same endpoint more than one
      time.

      To help to avoid such bugs this patch adds claimed flag to struct usb_ep,
      and  encapsulates endpoint claiming mechanism inside 
usb_ep_autoconfig_ss()
      and usb_ep_autoconfig_reset(), so now usb functions don't need to perform
      any additional actions to mark endpoint obtained from autoconfig as 
claimed.

      rcu_sched_state.  There can be no deadlock because rcu_preempt_state
      ->exp_funnel_mutex acquisition always precedes that of rcu_sched_state.
      But lockdep does not know that, so it gives false-positive splats.

      This commit therefore associates a separate lock_class_key structure
      with the rcu_sched_state structure's ->exp_funnel_mutex, allowing
      lockdep to see the lock ordering, avoiding the false positives.

      jbd2: limit number of reserved credits

      Currently there is no limitation on number of reserved credits we can
      ask for. If we ask for more reserved credits than 1/2 of maximum
      transaction size, or if total number of credits exceeds the maximum
      transaction size per operation (which is currently only possible with
      the former) we will spin forever in start_this_handle().

      Fix this by adding this limitation at the start of start_this_handle().

      This patch also removes the credit limitation 1/2 of maximum transaction
      size, since we really only want to limit the number of reserved credits.
      There is not much point to limit the credits if there is still space in
      the journal.

      This accidentally also fixes the online resize, where due to the
      limitation of the journal credits we're unable to grow file systems with
      1k block size and size between 16M and 32M. It has been partially fixed
      by 2c869b262a10ca99cb866d04087d75311587a30c, but not entirely.

      HID: wacom: Remove WACOM_QUIRK_NO_INPUT

      WACOM_QUIRK_NO_INPUT is a signal to the driver that input devices
      should not be created for a particular device. This quirk was used by
      the wireless receiver to prevent any devices from being created during
      the initial probe (defering it instead until we got a tablet connection
      event in 'wacom_wireless_work').

      This quirk is not necessary now that a device_type is associated with each
      device. Any input device allocated by 'wacom_allocate_inputs' which is
      not necessary for a particular device is freed in 'wacom_register_inputs'.
      In particular, none of the wireless receivers devices have the pen, pad,
      or touch device types set so the same effect is achieved without the need
      to be explicit.

      We now return early in wacom_retrieve_hid_descriptor for wireless devices
      (to prevent the device_type from being overridden) but since we ignore the
      HID descriptor for the wireless reciever anyway, this is not an issue.

      KVM: s390: host STP toleration for VMs

      If the host has STP enabled, the TOD of the host will be changed during
      synchronization phases. These are performed during a stop_machine() call.

      As the guest TOD is based on the host TOD, we have to make sure that:
      - no VCPU is in the SIE (implicitly guaranteed via stop_machine())
      - manual guest TOD calculations are not affected

      "Epoch" is the guest TOD clock delta to the host TOD clock. We have to
      adjust that value during the STP synchronization and make sure that code
      that accesses the epoch won't get interrupted in between (via disabling
      preemption).

      irqchip/gic: Ensure gic_cpu_if_up/down() programs correct GIC instance

      Commit 3228950621d9 ("irqchip: gic: Preserve gic V2 bypass bits in cpu
      ctrl register") added a new function, gic_cpu_if_up(), to program the
      GIC CPU_CTRL register. This function assumes that there is only one GIC
      instance present and hence always uses the chip data for the primary GIC
      controller. Although it is not common for there to be a secondary, some
      devices do support a secondary. Therefore, fix this by passing
      gic_cpu_if_up() a pointer to the appropriate chip data structure.

      Similarly, the function gic_cpu_if_down() only assumes that there is a
      single GIC instance present. Update this function so that an instance
      number is passed for the appropriate GIC and return an error code on
      failure. The vexpress TC2 (which has a single GIC) is currently the only
      user of this function and so update it accordingly. Note that because the
      TC2 only has a single GIC, the call to gic_cpu_if_down() should always
      be successful.

      irqchip/gic: Only allow the primary GIC to set the CPU map

      The gic_init_bases() function initialises an array that stores the mapping
      between the GIC and CPUs. This array is a global array that is
      unconditionally initialised on every call to gic_init_bases(). Although,
      it is not common for there to be more than one GIC instance, there are
      some devices that do support nested GIC controllers and gic_init_bases()
      can be called more than once.

      A 2nd call to gic_init_bases() will clear the previous CPU mapping and
      will only setup the mapping again for the CPU calling gic_init_bases().
      Fix this by only allowing the CPU map to be configured for the primary 
GIC.

      For secondary GICs the CPU map is not relevant because these GICs do not
      directly route the interrupts to the main CPU(s) but to other GICs or
      devices.

      s390/numa: add emulation support

      NUMA emulation (aka fake NUMA) distributes the available memory to nodes
      without using real topology information about the physical memory of the
      machine.

      Splitting the system memory into nodes replicates the memory management
      structures for each node. Particularly each node has its own "mm locks"
      and its own "kswapd" task.

      For large systems, under certain conditions, this results in improved
      system performance and/or latency based on reduced pressure on the mm
      locks and the kswapd tasks.

      NUMA emulation distributes CPUs to nodes while respecting the original
      machine topology information. This is done by trying to avoid to separate
      CPUs which reside on the same book or even on the same MC. Because the
      current Linux scheduler code requires a stable cpu to node mapping, cores
      are pinned to nodes when the first CPU thread is set online.

      This patch is based on the initial implementation from Philipp Hachtmann.

      The only way I can make this work is if ->status only has !PEBS events
      set, because if it has both set we'll take that slow path which masks
      out the !PEBS bits.

      After masking there are 3 options:

       - there is one bit set, and its @bit, we increment counts[bit].

       - there are multiple bits set, we increment error[] for each set bit,
         we do not increment counts[].

       - there are no bits set, we do nothing.

      The intent was to never increment counts[] for !PEBS events.

      Now if we start out with only a single !PEBS event set, we'll pass the
      test and increment counts[] for a !PEBS and hit the warn.

      When disabling a PEBS event, we need to drain the buffer. Doing so

      perf/x86/intel/lbr: Limit LBR accesses to TOS in callstack mode

      In callstack mode the LBR is not a ring buffer, but a stack that grows up
      and down. This means in  this case we don't need to access all LBRs, only 
the
      ones up to TOS. Do this optimization for the normal LBR read, and the 
context
      switch save/restore code. For save/restore it can be done 
unconditionally, as
      it only runs when call stack mode is active.

      This recovers some of the cost of going to 32 LBRs on Skylake.

      perf/x86/intel: Add Intel Skylake PMU support

      Add perf core PMU support for future Intel Skylake CPU cores.

      The code is based on Haswell/Broadwell.

      There is a new cache event list, based on the updated Haswell
      event list.

      Skylake has removed most counter constraints on basic
      events, so the basic constraints table now only has a single
      entry (plus the fixed counters).

      TSX support and various other setups are all shared with Haswell.

      Skylake has 32 LBR entries. Add a new LBR init function
      to set this up. The filters are all the same as Haswell.

      It also has a new LBR format with a separate LBR_INFO_* MSR,
      but that has been already added earlier.

      perf/x86/intel: Handle new arch perfmon v4 status bits

      ArchPerfmon v4 has some new status bits in GLOBAL_STATUS.

      These need to be ignored when deciding whether a NMI
      was an NMI, to avoid eating all NMIs when they
      stay set, see:

          b292d7a10487 ("perf/x86/intel: ignore CondChgd bit to avoid false NMI 
handling")

      This patch ignores the new ASIF bit, which indicates
      that SGX interfered with the PMU, and also the new
      LBR freezing bits, which are set when the LBRs get
      frozen, plus the existing CondChange (set by JTAG
      debuggers and some buggy BIOSes)

      perf/x86/intel/lbr: Add support for LBRv5

      Add support for the new LBRv5 format used on Intel Skylake CPUs.

      The flags for mispredict, abort, in_tx etc. moved to range of separate
      LBR_INFO_* MSRs. Teach the LBR code to read those. The original
      LBR registers stay the same, except they have full sign
      extension now.

      LBR_INFO also reports a cycle count to the last branch.
      Report the cycle information using the new "cycles" branch_info
      output field.

      In addition we have to context switch and clear the new INFO
      MSRs to avoid any information leaks.

      perf: Add cycles to branch_info

      Intel Skylake supports reporting the time in cycles a branch in the LBR
      took, to give a rough indication of the basic block performance.

      Export the cycle information in the branch_info structure.
      This can be done by just reusing some currently zero padding.

      This is just the generic header change. The architecture
      still needs to fill it in.

      There's no attempt to convert to real time, as we really
      want cycles here.

      perf/x86/intel/lbr: Allow time stamp for free running PEBSv3

      With PEBSv3 the PEBS record contains a time stamp. That means we can allow
      free-running PEBS without a PMI even if the user program requested a time 
stamp.
      This avoids the need to use -T to get free running PEBS, and also avoids
      any problems with mis-identifying MMAPs later.

      Move the free_running_flags state into a variable in x86_pmu and use it.
      This only works when no explicit clock_id is set.

      perf/x86/intel: Add support for PEBSv3 profiling

      PEBSv3 is the same as the existing PEBSv2 used on Haswell,
      but it adds a new TSC field. Add support to the generic
      PEBS handler to handle the new format, and overwrite
      the perf time stamp using the new native_sched_clock_from_tsc().

      Right now the time stamp is just slightly more accurate,
      as it is nearer the actual event trigger point. With
      the PEBS threshold > 1 patchkit it will be much more accurate,
      avoid the problems with MMAP mismatches earlier.
      The accurate time stamping is only implemented for
      the default trace clock for now.

      v2: Use _skl prefix. Check for default clock_id.

      perf/x86/intel/pt: Add new timing packet enables

      Intel PT chapter in the new Intel Architecture SDM adds several packets
      corresponding enable bits and registers that control packet generation.
      Also, additional bits in the Intel PT CPUID leaf were added to enumerate
      presence and parameters of these new packets and features.

      The packets and enables are:

        * CYC: cycle accurate mode, provides the number of cycles elapsed since
          previous CYC packet; its presence and available threshold values are
          enumerated via CPUID;

        * MTC: mini time counter packets, used for tracking TSC time between
          full TSC packets; its presence and available resolution options are
          enumerated via CPUID;

        * PSB packet period is now configurable, available period values are
          enumerated via CPUID.

      This patch adds corresponding bit and register definitions, pmu driver
      capabilities based on CPUID enumeration, new attribute format bits for
      the new featurens and extends event configuration validation function
      to take these into account.

      perf/x86/intel/pt: Do not force sync packets on every schedule-in

      Currently, the PT driver zeroes out the status register every time before
      starting the event. However, all the writable bits are already taken care
      of in pt_handle_status() function, except the new PacketByteCnt field,
      which in new versions of PT contains the number of packet bytes written
      since the last sync (PSB) packet. Zeroing it out before enabling PT forces
      a sync packet to be written. This means that, with the existing code, a
      sync packet (PSB and PSBEND, 18 bytes in total) will be generated every
      time a PT event is scheduled in.

      To avoid these unnecessary syncs and save a WRMSR in the fast path, this
      patch changes the default behavior to not clear PacketByteCnt field, so
      that the sync packets will be generated with the period specified as
      "psb_period" attribute config field. This has little impact on the trace
      data as the other packets that are normally sent within PSB+ (between PSB
      and PSBEND) have their own generation scenarios which do not depend on the
      sync packets.

      One exception where we do need to force PSB like this when tracing starts,
      so that the decoder has a clear sync point in the trace. For this purpose
      we aready have hw::itrace_started flag, which we are currently using to
      output PERF_RECORD_ITRACE_START. This patch moves setting itrace_started
      from perf core to the pmu::start, where it should still be 0 on the very
      first run.

      The check looked wrong, although I think it was actually safe.  TASK_SIZE

      a range breakpoint so large it started in user space and ended in kernel
      space.

      Nonetheless, let's fix up the check for the benefit of future
      readers.  A breakpoint is in the kernel if either end is in the
      kernel.

      perf/x86/hw_breakpoints: Disallow kernel breakpoints unless kprobe-safe

      Code on the kprobe blacklist doesn't want unexpected int3
      exceptions. It probably doesn't want unexpected debug exceptions
      either. Be safe: disallow breakpoints in nokprobes code.

      On non-CONFIG_KPROBES kernels, there is no kprobe blacklist.  In
      that case, disallow kernel breakpoints entirely.

      It will be particularly important to keep hw breakpoints out of the
      entry and NMI code once we move debug exceptions off the IST stack.

      to be advertised later to the OS via ieee80211_register_hw.
      The driver Rx indications for TCP Checksum is integrated within the
      standard Rx status. The driver responds to those indications as follows:
      If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY.
      Otherwise, report CHECKSUM_NONE.

      iwlwifi: pcie: provide a way to stop configuration if it is forbidden

      The firmware debug infrastructure allows the user to
      provide a firmware that will toggle a few registers to
      configure the debugging capabilities.
      On certain devices, certain operations are forbidden.
      Executing a forbidden operation will cause the hardware to
      die in a way that only driver unload / load will bring it
      back to life.
      Fortunately, there is a way to know in advance if those
      operations will be accepted by the device. This is where
      the new PRPH_BLOCKBIT operation plays its role. If the bit
      X from PRPH register Y is set, then we should prevent any
      further register configuration. When that happens, drop a
      line in the kernel log since this is really an error state:
      the user won't have his device configured as he expected.
      Add operations that will be used in the future:
      INDIRECT_ASSIGN, INDIRECT_SETBIT, and INDIRECT_CLEARBIT.

      Other debugging configurations (such as destination
      configuration for the monitor) will take place in any case.

      This reverts commit 088070a2f6575402d3dd82e1c5a4a8e1941805f6.

      When working in d0i3_on_idle mode, we explicitly go out
      of d0i3 on resume (so other potential commands could
      be sent).

      However, D0I3_DEFER_WAKEUP is currently cleared on
      resume complete (which happens only later on), causing
      d0i3 exit to timeout.

      Since mac80211 was modified to accept incoming frames
      once drv_resume was called, we can safely revert this
      patch, and handle the pending work on iwl_mvm_resume().

      iwlwifi: add wide firmware command infrastructure for TX

      As the firmware is slowly running out of command IDs and grouping of
      commands is desirable anyway, the firmware is extending the command
      header from 4 bytes to 8 bytes to introduce a group (in place of the
      former flags field, since that's always 0 on commands and thus can
      be easily used to distinguish between the two.

      In order to support this most easily in the driver widen the command
      command ID used in the command sending functions and encode the new
      values (group and version) in the ID. That way existing code doesn't
      have to be changed (since the higher bits are 0 automatically) and
      newer code can easily use the new ID generation function to create a
      value to use in place of just the command ID.

      very long time, probably since 4965. As a consequence, the field is
      always 0 and checking for a IWL_CMD_FAILED_MSK flag makes no sense.

      Rename the field to 'reserved', get rid of IWL_CMD_FAILED_MSK and
      all the code for it.

      iwlwifi: pcie: don't warn on long MPDUs when supported

      In iwlmvm firmwares, the Byte count written in the scheduler
      byte count table is in DWORDs and not in bytes.
      We should check that this value fits in the 12 bits and
      the value can be either in bits of in DWORD or bytes
      depending on the firmware. Check the value after the
      translation to DWORDs is done (if needed).

      In a few places, we were disabling interrupts but didn't

      Add calls to synchronize_irq() to ensure we finish handling

      could lead to a crash if the interrupt were to be handled
      later.

      iwlwifi: dvm: move ADD_STA response handling to sync command

      This driver currently has some very confusing ADD_STA response handling
      that runs asynchronously in the background for all of the commands, but
      is only really necessary for synchronous ones (the really asynchronous
      ones can only be done for already existing stations), and for the sync
      ones it actually waits for the RX handler to return a status code.

      Rework this to keep the debug printing in the handler, but do the code
      that's supposed to have an effect only for sync commands in the command
      sending function.

      iwlwifi: mvm: LRU-assign key offsets

      The current key offset assignment algorithm always uses the lowest
      unused key offset, which will potentially lead to issues when the
      firmware will change to take the key material for TX from the key
      table rather than from the TX command.

      In order to avoid those issues (and avoid forgetting about them)
      change the key offset allocation algorithm now to avoid reusing key
      offsets quickly.

      The new algorithm always picks as the next offset the least recently
      freed offset, i.e. the offset that has been unused for the longest
      amount of time. This is implemented by having a generation counter
      for each key offset that is incremented every time a key is deleted,
      except for the one that's deleted, which is reset to zero. Thus the
      highest counter is the key that's been unused longest.

      ipv4: apply lwtunnel encap for locally-generated packets

      lwtunnel encap is applied for forwarded packets, but not for
      locally-generated packets. This is because the output function is not
      overridden in __mkroute_output, unlike it is in __mkroute_input.

      The lwtunnel state is correctly set on the rth through the call to
      rt_set_nexthop, so all that needs to be done is to override the dst
      output function to be lwtunnel_output if there is lwtunnel state
      present and it requires output redirection.

      According to sample EEPROM datasheet (AT93Cx6), max frequency for

      mei: define async notification hbm commands

      FW has gained new capability where a FW client can asynchronously
      notify the host that an event has occurred in its process.
      The notification doesn't provide any data and host may need to query
      further the FW client in order to get details of the event.
      Host can subscribe or unsubscribe to the event notification via
      designated HBM commands, and also the notification is carried on
      a new HBM command.
      This patch adds definitions of asynchronous notification HBM commands.

      mei: bus: link client devices instead of host clients

      MEI bus was designed around nfc and was hard to extend.
      Instead of the hard coded way of adding the devices on the mei bus
      we scan the whole me client list and create a device for each
      eligible me client (mei_cl_bus_rescan); currently we support
      only clients with single connection and fixed address clients.
      NFC radio name detection is run as a fixup routine

      The patch replaces handling the device list based on struct me_cl
      to device list based on me_cl_devices. The creating a connection
      is pushed from the device creation time to device enablement.

      mei: bus: add reference to bus device in struct mei_cl_client

      Add reference to the bus device (mei_device) for easier access.
      To ensures that referencing cldev->bus is valid during cldev life time
      we increase the bus ref counter on a client device creation and drop it
      on the device release.

      mei: bus: fix drivers and devices names confusion

      In the mei bus layer there is use of different variables
      of driver and device types with no clear naming convention.
      There are generic struct device and struct driver,
      then mei_cl_{device, driver}, and finally mei_device which
      in this context serves as a bus device.

      The patch sets following naming convention:

      the variables of type struct device remains dev
      the variables of type struct driver remains drv
      the variables of type struct mei_cl_device are now cldev
      the variables of type struct mei_cl_driver are now cldrv
      the variables of type struct mei_device are now bus, in bus

      mei: do not access freed cb in blocking write

      The mei_cl_write function is giving up on a write cb ownership after it
      was sent or queued. The write cb is then freed in the completion
      handler. Especially during blocking write mei_cl_write function waits
      for the completion handler and then access the freed memory to fetch the
      written size.  The quick fix is to store the buffer size prior to
      sending, the size is not altered during the flow.

      act_bpf: properly support late binding of bpf action to a classifier

      Since the introduction of the BPF action in d23b8ad8ab23 ("tc: add BPF
      based action"), late binding was not working as expected. I.e. setting
      the action part for a classifier only via 'bpf index <num>', where <num>
      is the index of an existing action, is being rejected by the kernel due
      to other missing parameters.

      It doesn't make sense to require these parameters such as BPF opcodes
      etc, as they are not going to be used anyway: in this case, they're just
      allocated/parsed and then freed again w/o doing anything meaningful.

      Instead, parse and verify the remaining parameters *after* the test on
      tcf_hash_check(), when we really know that we're dealing with creation
      of a new action or replacement of an existing one and where late binding
      is thus irrelevant.

      After patch, test case is now working:

        FOO="1,6 0 0 4294967295,"
        tc actions add action bpf bytecode "$FOO"
        tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action 
bpf index 1
        tc actions show action bpf
          action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe
          index 1 ref 2 bind 1
        tc filter show dev foo
          filter protocol all pref 49152 bpf
          filter protocol all pref 49152 bpf handle 0x1 flowid 1:1 bytecode 
'1,6 0 0 4294967295'
          action order 1: bpf bytecode '1,6 0 0 4294967295' default-action pipe
          index 1 ref 2 bind 1

      Late binding of a BPF action can be useful for preloading maps (e.g. 
before
      they hit traffic) in case of eBPF programs, or to share a single eBPF 
action
      with multiple classifiers.

      Serial: imx: add dev_pm_ops to support suspend to ram/disk

      When system goes into low power states like SUSPEND_MEM and
      HIBERNATION, the hardware IP block may be powered off to reduce
      the power consumption. This power down may cause problems on
      some imx platforms, because the hardware settings are reset to
      its power on default values which may differ from the ones when
      it power off. This patch added the dev_pm_ops and implemented
      two callbacks: suspend_noirq and resume_noirq, which will save
      the necessory hardware parameters right before power down and
      recover them before system uses the hardware.

      Because added the dev_pm_ops, the old suspend/resume callbacks
      under platform_driver will not be called any more. Changed their
      prototypes and moved those two callbacks into dev_pm_ops too.

      bridge: mdb: add/del entry on all vlans if vlan_filter is enabled and vid 
is 0

      Before this patch when a vid was not specified, the entry was added with
      vid 0 which is useless when vlan_filtering is enabled. This patch makes
      the entry to be added on all configured vlans when vlan filtering is
      enabled and respectively deleted from all, if the entry vid is 0.
      This is also closer to the way fdb works with regard to vid 0 and vlan
      filtering.

      Example:
      Setup:
      $ bridge vlan add vid 256 dev eth4
      $ bridge vlan add vid 1024 dev eth4
      $ bridge vlan add vid 64 dev eth3
      $ bridge vlan add vid 128 dev eth3
      $ bridge vlan
      port      vlan ids
      eth3       1 PVID Egress Untagged
         64
         128

      eth4       1 PVID Egress Untagged
         256
         1024
      $ echo 1 > /sys/class/net/br0/bridge/vlan_filtering

      Before:
      $ bridge mdb add dev br0 port eth3 grp 239.0.0.1
      $ bridge mdb
      dev br0 port eth3 grp 239.0.0.1 temp

      After:
      $ bridge mdb add dev br0 port eth3 grp 239.0.0.1
      $ bridge mdb
      dev br0 port eth3 grp 239.0.0.1 temp vid 1
      dev br0 port eth3 grp 239.0.0.1 temp vid 128

      virtio_net: add gro capability

      Straightforward patch to add GRO processing to virtio_net.

      napi_complete_done() usage allows more aggressive aggregation,
      opted-in by setting /sys/class/net/xxx/gro_flush_timeout

      Tested:

      Setting /sys/class/net/xxx/gro_flush_timeout to 1000 nsec,
      Rick Jones reported following results.

      One VM of each on a pair of OpenStack compute nodes with E5-2650Lv3 CPUs
      and Intel 82599ES-based NICs. So, two "before" and two "after" VMs.
      The OpenStack compute nodes were running OpenStack Kilo, with VxLAN
      encapsulation being used through OVS so no GRO coming-up the host
      stack.  The compute nodes themselves were running a 3.14-based kernel.

      Single-stream netperf, CPU utilizations and thus service demands are
      based on intra-guest reported CPU.

      Input: zforce - make the interrupt GPIO optional

      Add support for hardware which uses an I2C Serializer / Deserializer
      (SerDes) to communicate with the zFroce touch driver. In this case the
      SerDes will be configured as an interrupt controller and the zForce driver
      will have no access to poll the GPIO line.

      To support this, we add two dedicated new GPIOs in the device tree:
      reset-gpios and irq-gpios, with the irq-gpios being optional.

      To not break the existing device trees, the index based 'gpios' entries
      are still supported, but marked as deprecated.

      With this, if the interrupt GPIO is available, either via the old or new
      device tree style, the while loop will read and handle the packets as long
      as the GPIO indicates that the interrupt is asserted (existing, unchanged
      driver behavior).

      If the interrupt GPIO isn't available, i.e. not configured via the new
      device tree style, we are falling back to one read per ISR invocation
      (new behavior to support the SerDes).

      Note that the gpiod functions help to handle the optional GPIO:
      devm_gpiod_get_index_optional() will return NULL in case the interrupt
      GPIO isn't available. And gpiod_get_value_cansleep() does cover this, too,
      by returning 0 in this case.

      thermal: consistently use int for temperatures

      The thermal code uses int, long and unsigned long for temperatures
      in different places.

      Using an unsigned type limits the thermal framework to positive
      temperatures without need. Also several drivers currently will report
      temperatures near UINT_MAX for temperatures below 0°C. This will probably
      immediately shut the machine down due to overtemperature if started below
      0°C.

      'long' is 64bit on several architectures. This is not needed since 
INT_MAX °mC
      is above the melting point of all known materials.

      Consistently use a plain 'int' for temperatures throughout the thermal 
code and
      the drivers. This only changes the places in the drivers where the 
temperature
      is passed around as pointer, when drivers internally use another type 
this is
      not changed.

      in the protected block.

      However, rx_complete() in f_printer.c calls spinlock on printer_dev->lock
      again, which will cause system hang.

      The following steps can reproduce this hang:

      1. Build the test program from Documentation/usb/gadget_printer.txt as
         g_printer
      2. Plug in the USB device to a host(such as Ubuntu).
      3. on the USB device system run:
         #modprobe g_printer.ko
         #./g_printer -read_data

      4. Unplug the USB device from the host

         The system will hang later.

      In order to avoid this deadlock, moving the spinlock from
      printer_func_disable() into printer_reset_interface() and excluding the 
block
      of calling dwc3_gadget_ep_disable(), in which the critical resource will 
be
      protected by its spinlock in rx_complete().

      This commit will fix the system hang with the following calltrace:

      It does not make much sense to call idr_preload with the same gfp mask
      as the following idr_alloc, but this is what we do in cgroup_idr_alloc.
      This patch fixes the idr_preload usage by making cgroup_idr_alloc call
      idr_alloc w/o __GFP_WAIT. Since it is now safe to call cgroup_idr_alloc
      with GFP_KERNEL, the patch also fixes all its callers appropriately.

      ARM: migrate to common PSCI client code

      Now that the common PSCI client code has been factored out to
      drivers/firmware, and made safe for 32-bit use, move the 32-bit ARM code
      over to it. This results in a moderate reduction of duplicated lines,
      and will prevent further duplication as the PSCI client code is updated
      for PSCI 1.0 and beyond.

      The two legacy platform users of the PSCI invocation code are updated to
      account for interface changes. In both cases the power state parameter
      (which is constant) is now generated using macros, so that the
      pack/unpack logic can be killed in preparation for PSCI 1.0 power state
      changes.

      ARM: psci: boot_secondary: replace __pa with virt_to_idmap

      On some PAE systems (e.g. TI Keystone), memory is above the 32-bit
      addressable limit, and the interconnect provides an aliased view of
      parts of physical memory in the 32-bit addressable space. This alias
      is strictly for boot time usage, and is not otherwise usable because
      of coherency limitations.

      In this case, virt_to_phys(secondary_startup) would return the
      physical address of the secondary CPU boot entry point, but on such
      systems, this would be above the 4GB limit.

      A separate function, virt_to_idmap(), has been provided to return a
      usable physical address for functions in the identity mapping, and
      this must be used in preference to virt_to_phys() or __pa() to find
      the physical entry point for functions in the identity mapping range.

      For other systems, virt_to_idmap() and virt_to_phys() return identical
      physical addresses.

      of: iommu: Silence misleading warning

      Printing "IOMMU is currently not supported for PCI" for
      every PCI device probed on a DT-based system proves to be
      both irritatingly noisy and confusing to users who have
      misinterpreted it to mean they can no longer use VFIO device
      assignment.

      Since configuring DMA masks for PCI devices via
      of_dma_configure() has not in fact changed anything with
      regard to IOMMUs there really is nothing to warn about here;
      shut it up.

      data->vbus_det is always 1 on boards without a (working) vbus-det, skip

      This fixes the sun4i usb phy code never turning on Vbus on such boards.

      drm/sti: atomic crtc/plane update

      Better fit STI hardware structure.
      Planes are no more responsible of updating mixer information such
      as z-order and status. It is now up to the CRTC atomic flush to
      do it. Plane actions (enable or disable) are performed atomically.
      Disabling of a plane is synchronize with the vsync event.

      sched/fair: Provide runnable_load_avg back to cfs_rq

      The cfs_rq's load_avg is composed of runnable_load_avg and 
blocked_load_avg.
      Before this series, sometimes the runnable_load_avg is used, and sometimes
      the load_avg is used. Completely replacing all uses of runnable_load_avg
      with load_avg may be too big a leap, i.e., the blocked_load_avg is 
concerned
      to result in overrated load. Therefore, we get runnable_load_avg back.

      The new cfs_rq's runnable_load_avg is improved to be updated with all of 
the
      runnable sched_eneities at the same time, so the one sched_entity updated 
and
      the others stale problem is solved.

      sched/fair: Rewrite runnable load and utilization average tracking

      The idea of runnable load average (let runnable time contribute to weight)
      was proposed by Paul Turner and Ben Segall, and it is still followed by
      this rewrite. This rewrite aims to solve the following issues:

      1. cfs_rq's load average (namely runnable_load_avg and blocked_load_avg) 
is
         updated at the granularity of an entity at a time, which results in the
         cfs_rq's load average is stale or partially updated: at any time, only
         one entity is up to date, all other entities are effectively lagging
         behind. This is undesirable.

         To illustrate, if we have n runnable entities in the cfs_rq, as time
         elapses, they certainly become outdated:

           t0: cfs_rq { e1_old, e2_old, ..., en_old }

         and when we update:

           t1: update e1, then we have cfs_rq { e1_new, e2_old, ..., en_old }

           t2: update e2, then we have cfs_rq { e1_old, e2_new, ..., en_old }

           ...

         We solve this by combining all runnable entities' load averages 
together
         in cfs_rq's avg, and update the cfs_rq's avg as a whole. This is based
         on the fact that if we regard the update as a function, then:

         w * update(e) = update(w * e) and

         update(e1) + update(e2) = update(e1 + e2), then

         w1 * update(e1) + w2 * update(e2) = update(w1 * e1 + w2 * e2)

         therefore, by this rewrite, we have an entirely updated cfs_rq at the
         time we update it:

           t1: update cfs_rq { e1_new, e2_new, ..., en_new }

           t2: update cfs_rq { e1_new, e2_new, ..., en_new }

           ...

      2. cfs_rq's load average is different between top rq->cfs_rq and other
         task_group's per CPU cfs_rqs in whether or not blocked_load_average
         contributes to the load.

         The basic idea behind runnable load average (the same for utilization)
         is that the blocked state is taken into account as opposed to only
         accounting for the currently runnable state. Therefore, the average
         should include both the runnable/running and blocked load averages.
         This rewrite does that.

         In addition, we also combine runnable/running and blocked averages
         of all entities into the cfs_rq's average, and update it together at
         once. This is based on the fact that:

           update(runnable) + update(blocked) = update(runnable + blocked)

         This significantly reduces the code as we don't need to separately
         maintain/update runnable/running load and blocked load.

      3. How task_group entities' share is calculated is complex and imprecise.

         We reduce the complexity in this rewrite to allow a very simple rule:
         the task_group's load_avg is aggregated from its per CPU cfs_rqs's
         load_avgs. Then group entity's weight is simply proportional to its
         own cfs_rq's load_avg / task_group's load_avg. To illustrate,

         if a task_group has { cfs_rq1, cfs_rq2, ..., cfs_rqn }, then,

         task_group_avg = cfs_rq1_avg + cfs_rq2_avg + ... + cfs_rqn_avg, then

         cfs_rqx's entity's share = cfs_rqx_avg / task_group_avg * task_group's 
share

      To sum up, this rewrite in principle is equivalent to the current one, but
      fixes the issues described above. Turns out, it significantly reduces the
      code complexity and hence increases clarity and efficiency. In addition,
      the new averages are more smooth/continuous (no spurious spikes and 
valleys)
      and updated more consistently and quickly to reflect the load dynamics.

      As a result, we have less load tracking overhead, better performance,
      and especially better power efficiency due to more balanced load.

      sched/preempt: Fix cond_resched_lock() and cond_resched_softirq()

      These functions check should_resched() before unlocking 
spinlock/bh-enable:
      preempt_count always non-zero => should_resched() always returns false.
      cond_resched_lock() worked iff spin_needbreak is set.

      This patch adds argument "preempt_offset" to should_resched().

      preempt_count offset constants for that:

        PREEMPT_DISABLE_OFFSET  - offset after preempt_disable()
        PREEMPT_LOCK_OFFSET     - offset after spin_lock()
        SOFTIRQ_DISABLE_OFFSET  - offset after local_bh_distable()
        SOFTIRQ_LOCK_OFFSET     - offset after spin_lock_bh()

      sched/fair: Beef up wake_wide()

      Josef Bacik reported that Facebook sees better performance with their
      1:N load (1 dispatch/node, N workers/node) when carrying an old patch
      to try very hard to wake to an idle CPU.  While looking at wake_wide(),
      I noticed that it doesn't pay attention to the wakeup of a many partner
      waker, returning 1 only when waking one of its many partners.

      Correct that, letting explicit domain flags override the heuristic.

      While at it, adjust task_struct bits, we don't need a 64-bit counter.

      sched: Introduce the 'trace_sched_waking' tracepoint

      Mathieu reported that since 317f394160e9 ("sched: Move the second half
      of ttwu() to the remote cpu") trace_sched_wakeup() can happen out of
      context of the waker.

      This is a problem when you want to analyse wakeup paths because it is
      now very hard to correlate the wakeup event to whoever issued the
      wakeup.

      OTOH trace_sched_wakeup() is issued at the point where we set
      p->state = TASK_RUNNING, which is right were we hand the task off to
      the scheduler, so this is an important point when looking at
      scheduling behaviour, up to here its been the wakeup path everything
      hereafter is due to scheduler policy.

      To bridge this gap, introduce a second tracepoint: trace_sched_waking.
      It is guaranteed to be called in the waker context.

      sched/cputime: Guarantee stime + utime == rtime

      While the current code guarantees monotonicity for stime and utime
      independently of one another, it does not guarantee that the sum of
      both is equal to the total time we started out with.

      This confuses things (and peoples) who look at this sum, like top, and
      will report >100% usage followed by a matching period of 0%.

      Rework the code to provide both individual monotonicity and a coherent
      sum.

      sched/fair: Avoid pulling all tasks in idle balancing

      In idle balancing where a CPU going idle pulls tasks from another CPU,
      a livelock may happen if the CPU pulls all tasks from another, makes
      it idle, and this iterates. So just avoid this.

      locking/static_keys: Add a new static_key interface

      There are various problems and short-comings with the current
      static_key interface:

       - static_key_{true,false}() read like a branch depending on the key
         value, instead of the actual likely/unlikely branch depending on
         init value.

       - static_key_{true,false}() are, as stated above, tied to the
         static_key init values STATIC_KEY_INIT_{TRUE,FALSE}.

       - we're limited to the 2 (out of 4) possible options that compile to
         a default NOP because that's what our arch_static_branch() assembly
         emits.

      So provide a new static_key interface:

        DEFINE_STATIC_KEY_TRUE(name);
        DEFINE_STATIC_KEY_FALSE(name);

      Which define a key of different types with an initial true/false
      value.

      Then allow:

         static_branch_likely()
         static_branch_unlikely()

      to take a key of either type and emit the right instruction for the
      case.

      This means adding a second arch_static_branch_jump() assembly helper
      which emits a JMP per default.

      In order to determine the right instruction for the right state,
      encode the branch type in the LSB of jump_entry::key.

      This is the final step in removing the naming confusion that has led to
      a stream of avoidable bugs such as:

        a833581e372a ("x86, perf: Fix static_key bug in load_mm_cr4()")

      ... but it also allows new static key combinations that will give us
      performance enhancements in the subsequent patches.

      jump_label: Rename JUMP_LABEL_{EN,DIS}ABLE to JUMP_LABEL_{JMP,NOP}

      Since we've already stepped away from ENABLE is a JMP and DISABLE is a
      NOP with the branch_default bits, and are going to make it even worse,
      rename it to make it all clearer.

      This way we don't mix multiple levels of logic attributes, but have a

      of a jump label is.

  commit 75d2270280686bff21b9ba66c7f3dd379c887981
  Author: Waiman Long <Waiman.Long@xxxxxx>
  Date:   Sat Jul 11 16:36:52 2015 -0400

      locking/pvqspinlock: Only kick CPU at unlock time

      For an over-committed guest with more vCPUs than physical CPUs
      available, it is possible that a vCPU may be kicked twice before
      getting the lock - once before it becomes queue head and once again
      before it gets the lock. All these CPU kicking and halting (VMEXIT)
      can be expensive and slow down system performance.

      This patch adds a new vCPU state (vcpu_hashed) which enables the code
      to delay CPU kicking until at unlock time. Once this state is set,
      the new lock holder will set _Q_SLOW_VAL and fill in the hash table
      on behalf of the halted queue head vCPU. The original vcpu_halted
      state will be used by pv_wait_node() only to differentiate other
      queue nodes from the qeue head.

      locking/qrwlock: Reduce reader/writer to reader lock transfer latency

      Currently, a reader will check first to make sure that the writer mode
      byte is cleared before incrementing the reader count. That waiting is
      not really necessary. It increases the latency in the reader/writer
      to reader transition and reduces readers performance.

      This patch eliminates that waiting. It also has the side effect
      of reducing the chance of writer lock stealing and improving the
      fairness of the lock. Using a locking microbenchmark, a 10-threads 5M
      locking loop of mostly readers (RW ratio = 10,000:1) has the following
      performance numbers in a Haswell-EX box:

      locking/pvqspinlock: Order pv_unhash() after cmpxchg() on unlock slowpath

      When we unlock in __pv_queued_spin_unlock(), a failed cmpxchg() on the 
lock
      value indicates that we need to take the slow-path and unhash the
      corresponding node blocked on the lock.

      Since a failed cmpxchg() does not provide any memory-ordering guarantees,
      it is possible that the node data could be read before the cmpxchg() on
      weakly-ordered architectures and therefore return a stale value, leading
      to hash corruption and/or a BUG().

      This patch adds an smb_rmb() following the failed cmpxchg operation, so
      that the unhashing is ordered after the lock has been checked.

      md/raid0: update queue parameter in a safer location.

      When a (e.g.) RAID5 array is reshaped to RAID0, the updating
      of queue parameters (e.g. max number of sectors per bio) is
      done in the wrong place.
      It should be part of ->run, but it is actually part of ->takeover.
      This means it happens before level_store() calls:

        blk_set_stacking_limits(&mddev->queue->limits);

      and so it ineffective.  This can lead to errors from underlying
      devices.

      So move all the relevant settings out of create_stripe_zones()
      and into raid0_run().

      As this can lead to a bug-on it is suitable for any -stable
      kernel which supports reshape to RAID0.  So 2.6.35 or later.
      As the bug has been present for five years there is no urgency,
      so no need to rush into -stable.

takeover")

      target: Drop iSCSI use of mutex around max_cmd_sn increment

      In a performance profile, taking a mutex in iscsit_increment_maxcmdsn()
      shows up very high.  However taking a mutex around "sess->max_cmd_sn += 1"
      seems pretty silly: we're not serializing against other contexts in
      any useful way.

      I did a quick audit and there don't appear to be any other places that
      use max_cmd_sn within the mutex more than once, so this lock can't be
      providing any useful serialization.

      ebpf: add skb->hash to offset map for usage in {cls, act}_bpf or filters

      Add skb->hash to the __sk_buff offset map, so it can be accessed from
      an eBPF program. We currently already do this for classic BPF filters,
      but not yet on eBPF, it might be useful as a demuxer in combination with
      helpers like bpf_clone_redirect(), toy example:

        __section("cls-lb") int ingress_main(struct __sk_buff *skb)
        {
          unsigned int which = 3 + (skb->hash & 7);
          /* bpf_skb_store_bytes(skb, ...); */
          /* bpf_l{3,4}_csum_replace(skb, ...); */
          bpf_clone_redirect(skb, which, 0);
          return -1;
        }

      I was thinking whether to add skb_get_hash(), but then concluded the
      raw skb->hash seems fine in this case: we can directly access the hash
      w/o extra eBPF helper function call, it's filled out by many NICs on
      ingress, and in case the entropy level would not be sufficient, people
      can still implement their own specific sw fallback hash mix anyway.

      bnx2x: Correct logic for pvid configuration.

      Commit 05cc5a39ddb7 ("bnx2x: add vlan filtering offload") has introduced
      an incorrect logic for checking whether pvid should be configured for
      a vf, causing the hypervisor driver to send unneeded ramrods for all of
      the vfs each time a pvid has changed.

      tools: iio: fix mask for 32 bit sensor data

      When the the sensor data uses 32 bits out of 32, generic_buffer prints
      the value 0 for all data read.

      In this case, the mask is shifted 32 bits, which is beyond the size of
      an integer. This will lead to the mask always being 0. Before printing,
      the mask is applied to the raw value, thus generating a final value of 0.

      Fix the mask by shifting a 64 bit value instead of an integer.

      iio: Export OF module alias information in missing drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      Flow labels are important since they are the desired solution for
      network devices to perform ECMP and RSS (RFC6437 and RFC6438).
      Traditionally, devices perform a 5-tuple hash on packets that
      includes port numbers. For the most part, these devices can only
      compute 5-tuple hashes for TCP and UDP. This severely limits our ability
      to get good network load balancing for other protocols (IPIP, GRE,ESP,
      etc.), and hence we are limited in using other protocols. Unfortunately,
      this method is accepted as the de facto standard to the extent that
      there are several proposals to encapsulate protocols in UDP _just_ for
      the purposes for getting ECMP to work. With hosts generating flow labels
      and devices taking them as input into ECMP (several already do), we can
      start to fix this fundamental problem.

      This patch set:
       - Changes IPV6_FLOWINFO sockopt to be opt-out of flow labels for
         connections rather than opt-in
       - Disable flow label state ranges sysctl by default
       - Enable auto flow labels sysctl by default

      v2:
        - Added functions to create an skb->hash based on flowi4 and flowi6.
          These are called in output path when creating a packet
        - Call skb_get_hash_flowi6 in ip6_make_flowlabel
        - Implement the auto_flowlabels sysctl as a mode for auto flowlabels.
          There are four modes which correspond to flow labels being enabled
          and whether socket option can be used to opt in or opt out of
          using them

      ipv6: Disable flowlabel state ranges by default

      Per RFC6437 stateful flow labels (e.g. labels set by flow label manager)
      cannot "disturb" nodes taking part in stateless flow labels. While the
      ranges only reduce the flow label entropy by one bit, it is conceivable
      that this might bias the algorithm on some routers causing a load
      imbalance. For best results on the Internet we really need the full
      20 bits.

      0: flow labels are disabled
      1: flow labels are enabled, sockets can opt-out

      3: flow labels are enabled and enforced, no opt-out for sockets

      The code that tests for high and low xmit watermarks was consolidatedand
      simplified. The output behavior should be identical, with the exception
      of an off-by-one error being corrected in the tests done when the counters
      overflowed.

      staging: unisys: visornic_resume needs to mirror _serverdown_complete

      Previously we simplified the serverdown function to basically turn it
      into a dev_close(), but missed the analogous logic in visornic_resume()
      (which is essentially the "book-end" of visornic_serverdown_complete()).
      As a result, during IO partition recovery, the nic would go closed when
      the IO partition went away, but would never be opened again when the IO
      partition came back.

      This patch changes visornic_resume() to use dev_open(), so that it once
      again plays nicely with visornic_serverdown_complete().  Because
      dev_open() forces us into the visornic_open() path, other logic in
      visornic_resume() was no longer necessary, and lended to simplifying
      visornic_resume() even more.

      staging: unisys: visornic - correctly reset flag prior to send_enbdis()

      Because devdata->enab_dis_acked is the flag used to determine whether an
      enable/disable operation to the IO partition has completed, it should
      always be cleared prior to initiating the operation.  The call added to
      visornic_enable_with_timeout() added in this patch makes the usage there
      consistent with visornic_disable_with_timeout().

      staging: unisys: visornic - prevent lock recursion after IO recovery

      In the patch which changed the serverdown logic to by synchronous, we
      were
      mistakenly holding on to devdata->priv_lock in the call to
      visornic_serverdown_complete(), which ultimately ended up recursively
      attempting to grab the same lock via the path:

          --> dev_close
              --> visornic_close()
                  --> visornic_disable_with_timeout()

      ====================
      net: GENET, SYSTEMPORT and DSA netconsole

      This patch series adds support for netconsole in the GENET, SYSTEMPORT 
and DSA
      drivers.

      A small refactoring to the DSA transmit path is required to avoid 
duplicating
      the dsa_netpoll_send_skb() into each and every tagging protocol supported.

      Testing on e.g: mv643xx_eth and/or e1000e would be much appreciated!

      Changes in v2:

      - properly disable/enable interrupts in GENET and SYSTEMPORT

      - pass the reallocated SKB back to dsa_slave_xmit() in case a tag 
protocol had to
        alter the original SKB

      net: dsa: Add netconsole support

      Add support for using DSA slave network devices with netconsole, which
      requires us to allocate and free custom netpoll instances and invoke the
      parent network device poll controller callback.

      In order for netconsole to work, we need to construct the DSA tag, but
      not queue the skb for transmission on the master network device xmit
      function.

      net: dsa: Refactor transmit path to eliminate duplication

      All tagging protocols do the same thing: increment device statistics,
      make room for the tag to be inserted, create the tag, invoke the parent
      network device transmit function.

      In order to prepare for adding netpoll support, which requires the tag
      creation, but not using the parent network device transmit function, do
      some little refactoring which eliminates duplication between the 4
      tagging protocols supported.

      We need to return a sk_buff pointer back to the caller because the tag
      specific transmit function may have to reallocate the original skb (e.g:
      tag_trailer.c) and this is the one we should be transmitting, not the
      original sk_buff we were passed.

      The policy in the net driver is to attempt MCDI commands and
      then handle any EPERM error codes appropriately when returned
      by unprivileged functions.
      The ethtool selftest contains some tests which are useful on
      an unprivileged function, such as the event queue interrupt
      tests, but other tests cannot be performed as the function
      does not have the required permissions.

      If a test returns -EPERM, act as though the test was not run

      The UEFI driver would enable zero length, and the Linux driver doesn't
      need it. Zero length let the hw complete the transfer with length 0,
      when there is no received packet. It would add the load of USB host

      bpf: add helpers to access tunnel metadata

      Introduce helpers to let eBPF programs attached to TC manipulate tunnel 
metadata:
      bpf_skb_[gs]et_tunnel_key(skb, key, size, flags)
      skb: pointer to skb
      key: pointer to 'struct bpf_tunnel_key'
      size: size of 'struct bpf_tunnel_key'
      flags: room for future extensions

      First eBPF program that uses these helpers will allocate per_cpu
      metadata_dst structures that will be used on TX.
      On RX metadata_dst is allocated by tunnel driver.

      Typical usage for TX:
      struct bpf_tunnel_key tkey;
      ... populate tkey ...
      bpf_skb_set_tunnel_key(skb, &tkey, sizeof(tkey), 0);
      bpf_clone_redirect(skb, vxlan_dev_ifindex, 0);

      RX:
      struct bpf_tunnel_key tkey = {};
      bpf_skb_get_tunnel_key(skb, &tkey, sizeof(tkey), 0);
      ... lookup or redirect based on tkey ...

      'struct bpf_tunnel_key' will be extended in the future by adding
      elements to the end and the 'size' argument will indicate which fields
      are populated, thereby keeping backwards compatibility.
      The 'flags' argument may be used as well when the 'size' is not enough or
      to indicate completely different layout of bpf_tunnel_key.

      PM / suspend: make sync() on suspend-to-RAM build-time optional

      The Linux kernel suspend path has traditionally invoked sys_sync()
      before freezing user threads.

      But sys_sync() can be expensive, and some user-space OS's do not want
      the kernel to pay the cost of sys_sync() on every suspend -- preferring
      invoke sync() from user-space if/when they want it.

      So make sys_sync on suspend build-time optional.

      The default is unchanged.

      PM / Domains: Return -EPROBE_DEFER if we fail to init or turn-on domain

      When a device is probed, the function dev_pm_domain_attach() is called
      to see if there is a power-domain that is associated with the device and
      needs to be turned on. If dev_pm_domain_attach() does not return
      -EPROBE_DEFER then the device will be probed.

      For devices using genpd, dev_pm_domain_attach() will call
      genpd_dev_pm_attach(). If genpd_dev_pm_attach() does not find a power
      domain associated with the device then it returns an error code not
      equal to -EPROBE_DEFER to allow the device to be probed. However, if
      genpd_dev_pm_attach() does find a power-domain that is associated with
      the device, then it does not return -EPROBE_DEFER on failure and hence
      the device will still be probed. Furthermore, genpd_dev_pm_attach() does
      not check the error code returned by pm_genpd_poweron() to see if the
      power-domain was turned on successfully.

      Fix this by checking the return code from pm_genpd_poweron() and
      returning -EPROBE_DEFER from genpd_dev_pm_attach on failure, if there
      is a power-domain associated with the device.

      PM / Domains: Remove intermediate states from the power off sequence

      Genpd's ->runtime_suspend() (assigned to pm_genpd_runtime_suspend())
      doesn't immediately walk the hierarchy of ->runtime_suspend() callbacks.
      Instead, pm_genpd_runtime_suspend() calls pm_genpd_poweroff() which
      postpones that until *all* the devices in the genpd are runtime suspended.

      When pm_genpd_poweroff() discovers that the last device in the genpd is
      about to be runtime suspended, it calls __pm_genpd_save_device() for *all*
      the devices in the genpd sequentially. Furthermore,
      __pm_genpd_save_device() invokes the ->start() callback, walks the
      hierarchy of the ->runtime_suspend() callbacks and invokes the ->stop()
      callback. This causes a "thundering herd" problem.

      Let's address this issue by having pm_genpd_runtime_suspend() immediately
      walk the hierarchy of the ->runtime_suspend() callbacks, instead of
      postponing that to the power off sequence via pm_genpd_poweroff(). If the
      selected ->runtime_suspend() callback doesn't return an error code, call
      pm_genpd_poweroff() to see if it's feasible to also power off the PM
      domain.

      Adopting this change enables us to simplify parts of the code in genpd,
      for example the locking mechanism. Additionally, it gives some positive
      side effects, as described below.

      i)
      One device's ->runtime_resume() latency is no longer affected by other
      devices' latencies in a genpd.

      The complexity genpd has to support the option to abort the power off
      sequence suffers from latency issues. More precisely, a device that is
      requested to be runtime resumed, may end up waiting for
      __pm_genpd_save_device() to complete its operations for *another* device.
      That's because pm_genpd_poweroff() can't confirm an abort request while it
      waits for __pm_genpd_save_device() to return.

      As this patch removes the intermediate states in pm_genpd_poweroff() while
      powering off the PM domain, we no longer need the ability to abort that
      sequence.

      ii)
      Make pm_runtime[_status]_suspended() reliable when used with genpd.

      Until the last device in a genpd becomes idle, pm_genpd_runtime_suspend()
      will return 0 without actually walking the hierarchy of the
      ->runtime_suspend() callbacks. However, by returning 0 the runtime PM core
      considers the device as runtime_suspended, so
      pm_runtime[_status]_suspended() will return true, even though the device
      isn't (yet) runtime suspended.

      After this patch, since pm_genpd_runtime_suspend() immediately walks the
      hierarchy of the ->runtime_suspend() callbacks,
      pm_runtime[_status]_suspended() will accurately reflect the status of the
      device.

      iii)
      Enable fine-grained PM through runtime PM callbacks in drivers/subsystems.

      There are currently cases were drivers/subsystems implements runtime PM
      callbacks to deploy fine-grained PM (e.g. gate clocks, move pinctrl to
      power-save state, etc.). While using the genpd, pm_genpd_runtime_suspend()
      postpones invoking these callbacks until *all* the devices in the genpd
      are runtime suspended. In essence, one runtime resumed device prevents
      fine-grained PM for other devices within the same genpd.

      After this patch, since pm_genpd_runtime_suspend() immediately walks the
      hierarchy of the ->runtime_suspend() callbacks, fine-grained PM is enabled
      throughout all the levels of runtime PM callbacks.

      iiii)
      Enable fine-grained PM for IRQ safe devices

      Per the definition for an IRQ safe device, its runtime PM callbacks must
      be able to execute in atomic context. In the path while genpd walks the
      hierarchy of the ->runtime_suspend() callbacks for the device, it uses a
      mutex. Therefore, genpd prevents that path to be executed for IRQ safe
      devices.

      As this patch changes pm_genpd_runtime_suspend() to immediately walk the
      hierarchy of the ->runtime_suspend() callbacks and without needing to use
      a mutex, fine-grained PM is enabled throughout all the levels of runtime
      PM callbacks for IRQ safe devices.

      Unfortunately this patch also comes with a drawback, as described in the
      summary below.

      Driver's/subsystem's runtime PM callbacks may be invoked even when the
      genpd hasn't actually powered off the PM domain, potentially introducing
      unnecessary latency.

      However, in most cases, saving/restoring register contexts for devices are
      typically fast operations or can be optimized in device specific ways
      (e.g. shadow copies of register contents in memory, device-specific checks
      to see if context has been lost before restoring context, etc.).

      Still, in some cases the driver/subsystem may suffer from latency if
      runtime PM is used in a very fine-grained manner (e.g. for each IO request
      or xfer). To prevent that extra overhead, the driver/subsystem may deploy
      the runtime PM autosuspend feature.

      intel_pstate: Fix possible overflow complained by Coverity

      Coverity scanning performed on intel_pstate.c shows possible
      overflow when doing left shifting:
      val = pstate << 8;
      since pstate is of type integer, while val is of u64, left shifting
      pstate might lead to potential loss of upper bits. Say, if pstate equals
      0x4000 0000, after pstate << 8 we will get zero assigned to val.
      Although pstate will not likely be that big, this patch cast the left
      operand to u64 before performing the left shift, to avoid complaining
      from Coverity.

      cpufreq: Correct a freq check in cpufreq_set_policy()

      This check was originally added by commit 9c9a43ed2734 ("[CPUFREQ]
      return error when failing to set minfreq").It attempt to return an error
      on obviously incorrect limits when we echo xxx >.../scaling_max,min_freq
      Actually we just need check if new_policy->min > new_policy->max.
      Because at least one of max/min is copied from cpufreq_get_policy().

      For example, when we echo xxx > .../scaling_min_freq, new_policy is
      copied from policy in cpufreq_get_policy. new_policy->max is same with
      policy->max. new_policy->min is set to a new value.

      Let me explain it in deduction method, first statement in if ():
      new_policy->min > policy->max
      policy->max == new_policy->max
      ==> new_policy->min > new_policy->max

      second statement in if():
      new_policy->max < policy->min
      policy->max < policy->min
      ==>new_policy->min > new_policy->max (induction method)

      So we have proved that we only need check if new_policy->min >
      new_policy->max.

      After apply this patch, we can also modify ->min and ->max at same time
      if new freq range is very much different from current freq range. For
      example, if current freq range is 480000-960000, then we want to set
      this range to 1120000-2240000, we would fail in the past because
      new_policy->min > policy->max. As long as the cpufreq range is valid, we
      has no reason to reject the user. So correct the check to avoid such
      case.

      The irq argument of most interrupt flow handlers is unused or merily
      used instead of a local variable. The handlers which need the irq
      argument can retrieve the irq number from the irq descriptor.

      Search and update was done with coccinelle and the invaluable help of
      Julia Lawall.

      spi: pxa2xx: Add support for Intel Sunrisepoint

      Major difference in LPSS SPI between Intel Sunrisepoint PCH and earlier
      platforms is an integrated DMA (iDMA) engine. iDMA is an IP that is 
private
      for each LPSS host controller (UART/SPI/I2C). Other differences are 
private
      register space offset, a few private registers that are in different
      location and FIFO thresholds.

      Intel Sunrisepoint LPSS SPI and iDMA devices are probed and registered in
      MFD layer as platform devices. Here these compound devices are detected by
      matching against known PCI IDs. This allows us to share
      pxa2xx_spi_acpi_get_pdata() for setting up the platform data instead of
      duplicating it in MFD part.

      This patch adds configuration for Intel Sunrisepoint LPSS SPI, above
      detection and DMA filter function that picks the DMA channel only from an
      associated iDMA block.

      ASoC: Export OF module alias information in missing codec drivers

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      ARM: 8392/3: smp: Only expose /sys/.../cpuX/online if hotpluggable

      Writes to /sys/.../cpuX/online fail if we determine the platform
      doesn't support hotplug for that CPU. Furthermore, if the cpu_die
      op isn't specified the system hangs when we try to offline a CPU
      and it comes right back online unexpectedly. Let's figure this
      stuff out before we make the sysfs nodes so that the online file
      doesn't even exist if it isn't (at least sometimes) possible to
      hotplug the CPU.

      Add a new 'cpu_can_disable' op and repoint all 'cpu_disable'
      implementations at it because all implementers use the op to
      indicate if a CPU can be hotplugged or not in a static fashion.
      With PSCI we may need to add a 'cpu_disable' op so that the
      secure OS can be migrated off the CPU we're trying to hotplug.
      In this case, the 'cpu_can_disable' op will indicate that all
      CPUs are hotpluggable by returning true, but the 'cpu_disable' op
      will make a PSCI migration call and occasionally fail, denying
      the hotplug of a CPU. This shouldn't be any worse than x86 where
      we may indicate that all CPUs are hotpluggable but occasionally
      we can't offline a CPU due to check_irq_vectors_for_cpu_disable()
      failing to find a CPU to move vectors to.

      Enable the otg/drc usb controller on the Ippo Q8H-A33 tablet, for now it
      is enabled in host-only mode, because true OTG support requires support
      for detecting and enabling Vbus through the axp221 pmic.

      For this to work the Vbus on the port must be enabled by u-boot,
      or a powered hub must be used.

      arm64: restore cpu suspend/resume functionality

      Commit 4b3dc9679cf7 ("arm64: force CONFIG_SMP=y and remove redundant 
#ifdefs")
      accidentally retained code for !CONFIG_SMP in cpu_resume function. This
      resulted in the hash index being zeroed in x7 after proper computation,
      which is then used to get the cpu context pointer while resuming.

      This patch removes the remanant code and restores back the cpu suspend/
      resume functionality.

      ARM: perf: replace arch_find_n_match_cpu_physical_id with 
of_cpu_device_node_get

      arch_find_n_match_cpu_physical_id parses the device tree to get the
      device node for a given logical cpu index. However, since ARM PMUs get
      probed after the CPU device nodes are stashed while registering the
      cpus, we can use of_cpu_device_node_get to avoid another DT parse.

      This patch replaces arch_find_n_match_cpu_physical_id with
      of_cpu_device_node_get to reuse the stashed value directly instead.

      ARM: perf: extend interrupt-affinity property for PPIs

      On systems containing multiple, heterogeneous clusters we need a way to
      associate a PMU "device" with the CPU(s) on which it exists. For PMUs
      that signal overflow with SPIs, this relationship is determined via the
      "interrupt-affinity" property, which contains a list of phandles to CPU
      nodes for the PMU. For PMUs using PPIs, the per-cpu nature of the
      interrupt isn't enough to determine the set of CPUs which actually
      contain the device.

      This patch allows the interrupt-affinity property to be specified on a
      PMU node irrespective of the interrupt type. For PPIs, it identifies
      the set of CPUs signalling the PPI in question.

      arm: perf: Set affinity for PPI based PMUs

      For PPI based PMUs, we bail out early in of_pmu_irq_cfg() without
      setting the PMU's supported_cpus bitmap. This causes the
      smp_call_function_any() in armv7_probe_num_events() to fail. Set
      the bitmap to be all CPUs so that we properly probe PMUs that use
      PPIs.

      usb: gadget: mass_storage: Fix freeing luns sysfs implementation

      Use device_is_registered() instad of sysfs flag to determine if
      we should free sysfs representation of particular LUN.

      sysfs flag in fsg common determines if luns attributes should be
      exposed using sysfs. This flag is used when creating and freeing
      luns. Unfortunately there is no guarantee that this flag will not
      be changed between creation and removal of particular LUN. Especially
      because of lun.0 which is created during allocating instance of
      function. This may lead to resource leak or NULL pointer dereference:

      staging: emxx_udc: add missing usb_ep_set_maxpacket_limit()

      Since maxpacket_limit was introduced all UDC drivers should use
      usb_ep_set_maxpacket_limit() function instead of setting maxpacket value
      manually. ep.maxpacket_limit contains actual maximum maxpacket value
      supported by hardware which is needed by epautoconf.

      usb: gadget: midi: avoid redundant f_midi_set_alt() call

      Function midi registers two interfaces with single set_alt() function
      which means that f_midi_set_alt() is called twice when configuration
      is set. That means that endpoint initialization and ep request allocation
      is done two times. To avoid this problem we do such things only once,
      for interface number 1 (MIDI Streaming interface).

      x86/vm86: Use the normal pt_regs area for vm86

      Change to use the normal pt_regs area to enter and exit vm86
      mode.  This is done by increasing the padding at the top of the
      stack to make room for the extra vm86 segment slots in the IRET
      frame.  It then saves the 32-bit regs in the off-stack vm86
      data, and copies in the vm86 regs.  Exiting back to 32-bit mode
      does the reverse.  This allows removing the hacks to jump
      directly into the exit asm code due to having to change the
      stack pointer.  Returning normally from the vm86 syscall and the
      exception handlers allows things like ptrace and auditing to work 
properly.

      iommu/arm-smmu: Sort out coherency

      Currently, we detect whether the SMMU has coherent page table walk
      capability from the IDR0.CTTW field, and base our cache maintenance
      decisions on that. In preparation for fixing the bogus DMA API usage,
      however, we need to ensure that the DMA API agrees about this, which
      necessitates deferring to the dma-coherent property in the device tree
      for the final say.

      As an added bonus, since systems exist where an external CTTW signal
      has been tied off incorrectly at integration, allowing DT to override
      it offers a neat workaround for coherency issues with such SMMUs.

      USB: io_ti: Add heartbeat to keep idle EP/416 ports from disconnecting

      When using Edgeport/416 models with newer firmware (sometime after
      firmware version 4.80.0), idle ports are automatically bounced
      (disconnected and then reconnected) approximately every 60 seconds.
      This breaks programs (e.g: minicom) where idle periods are common,
      normal and expected.

      I confirmed with the manufacturer (Digi International) that Edgeport/416
      models now ship from the factory with firmware that expects periodic
      "heartbeat" queries from the driver to keep idle ports alive.  This
      patch implements heartbeat support using the mechanism Digi suggested
      (periodically requesting an I2C descriptor address) that appears effective
      on Edgeports running the newer firmware (that require it) and benign on
      Edgeport devices running older firmware.  Since we know that Edgeport
      firmware version 4.80 (the version distributed in /lib/firmware/down3.bin
      and used for Edgeports that are either running still older versions or
      have no onboard non-volatile firmware image) does not require heartbeat
      support, this patch schedules heartbeats only on Edgeport/416 devices,
      and only if they are running firmware versions newer than 4.80.

      USB: io_ti: Add firmware image sanity checks

      Do what we can to verify that the driver's firmware image is valid
      (before attempting to download it to the Edgeport) by adding a new
      function, check_fw_sanity(), and a call to it in in download_fw().

      Note: It looks like some Edgeports (models like the EP/416 with on-board
      E2PROM) may be able to function even if the on-disk firmware image is
      bad or missing, iff their local E2PROM versions are valid.  But most
      Edgeport models (I've tried EP/1 and EP/8) do not appear to have this
      capability and they always rely on the on-disk firmware image.

      I tested an implementation that calls the new check_fw_sanity()
      function at the top of download_fw() and, rather than simply returning
      an error if the firmware image is bad or missing, it saves the result
      and defers the decision until later when it may find that it is running
      on a E2PROM-equipped device with a valid image.  But I think this is
      messier than it is worth (adding still more messiness to the already
      very messy download_fw()) for such a marginal possible benefit.  So, at
      least for now, I have chosen the much simpler approach of returning an
      error whenever edge_startup() fails to load an on-disk firmware image, or
      check_fw_sanity() indicates that it is unusable.

      USB: io_ti: Fix firmware version handling

      The io_ti driver fails to download firmware to Edgeport
      devices such as the EP/416, even when the on-disk firmware image
      (/lib/firmware/edgeport/down3.bin) is more current than the version
      on the EP/416.  The current download code is broken in a few ways.
      Notably it mis-uses global variables OperationalMajorVersion and
      OperationalMinorVersion (reading their values before they've been
      properly initialized and subsequently initializing them multiple times
      without synchronization).  This patch drops the global variables and
      replaces the redundant calls to request_firmware()/release_firmware()
      in download_fw() with a single call pair in edge_startup(); the firmware
      image pointer is then passed to download_fw() and build_i2c_fw_hdr().

      USB: io_ti: Increase insufficient timeout for firmware downloads

      The io_ti driver fails to download firmware to Edgeport devices such as
      the EP/416 and EP/421 (devices with on-board E2PROM).  One of the problems
      is that the default 1 second timeout in ti_vsend_sync() is insufficient
      for download operations.  This patch increases the download timeout to
      10 seconds.

      uprobes: Use vm_special_mapping to name the XOL vma

      Change xol_add_vma() to use _install_special_mapping(), this way
      we can name the vma installed by uprobes. Currently it looks
      like private anonymous mapping, this is confusing and
      complicates the debugging. With this change /proc/$pid/maps
      reports "[uprobes]".

      As a side effect this will cause core dumps to include the XOL vma
      and I think this is good; this can help to debug the problem if
      the app crashed because it was probed.

      install_special_mapping(pages) expects that "pages" is the zero-
      terminated array while xol_add_vma() passes &area->page, this
      means that special_mapping_fault() can wrongly use the next
      member in xol_area (vaddr) as "struct page *".

      Fortunately, this area is not expandable so pgoff != 0 isn't
      possible (modulo bugs in special_mapping_vmops), but still this
      does not look good.

      uprobes/x86: Make arch_uretprobe_is_alive(RP_CHECK_CALL) more clever

      The previous change documents that cleanup_return_instances()
      can't always detect the dead frames, the stack can grow. But
      there is one special case which imho worth fixing:
      arch_uretprobe_is_alive() can return true when the stack didn't
      actually grow, but the next "call" insn uses the already
      invalidated frame.

      Test-case:

        #include <stdio.h>
        #include <setjmp.h>

        jmp_buf jmp;
        int nr = 1024;

        void func_2(void)
        {
                if (--nr == 0)
                        return;
                longjmp(jmp, 1);
        }

        void func_1(void)
        {
                setjmp(jmp);
                func_2();
        }

        int main(void)
        {
                func_1();
                return 0;
        }

      If you ret-probe func_1() and func_2() prepare_uretprobe() hits
      the MAX_URETPROBE_DEPTH limit and "return" from func_2() is not
      reported.

      When we know that the new call is not chained, we can do the
      more strict check. In this case "sp" points to the new ret-addr,
      so every frame which uses the same "sp" must be dead. The only
      complication is that arch_uretprobe_is_alive() needs to know was
      it chained or not, so we add the new RP_CHECK_CHAIN_CALL enum
      and change prepare_uretprobe() to pass RP_CHECK_CALL only if
      !chained.

      Note: arch_uretprobe_is_alive() could also re-read *sp and check
      if this word is still trampoline_vaddr. This could obviously
      improve the logic, but I would like to avoid another
      copy_from_user() especially in the case when we can't avoid the
      false "alive == T" positives.

      uprobes: Change prepare_uretprobe() to (try to) flush the dead frames

      Change prepare_uretprobe() to flush the !arch_uretprobe_is_alive()
      return_instance's. This is not needed correctness-wise, but can help
      to avoid the failure caused by MAX_URETPROBE_DEPTH.

      Note: in this case arch_uretprobe_is_alive() can be false
      positive, the stack can grow after longjmp(). Unfortunately, the
      kernel can't 100% solve this problem, but see the next patch.

      uprobes: Change handle_trampoline() to flush the frames invalidated by 
longjmp()

      Test-case:

        #include <stdio.h>
        #include <setjmp.h>

        jmp_buf jmp;

        void func_2(void)
        {
                longjmp(jmp, 1);
        }

        void func_1(void)
        {
                if (setjmp(jmp))
                        return;
                func_2();
                printf("ERR!! I am running on the caller's stack\n");
        }

        int main(void)
        {
                func_1();
                return 0;
        }

      fails if you probe func_1() and func_2() because
      handle_trampoline() assumes that the probed function should must
      return and hit the bp installed be prepare_uretprobe(). But in
      this case func_2() does not return, so when func_1() returns the
      kernel uses the no longer valid return_instance of func_2().

      Change handle_trampoline() to unwind ->return_instances until we
      know that the next chain is alive or NULL, this ensures that the
      current chain is the last we need to report and free.

      Alternatively, every return_instance could use unique
      trampoline_vaddr, in this case we could use it as a key. And
      this could solve the problem with sigaltstack() automatically.

      But this approach needs more changes, and it puts the "hard"
      limit on MAX_URETPROBE_DEPTH. Plus it can not solve another
      problem partially fixed by the next patch.

      Note: this change has no effect on !x86, the arch-agnostic
      version of arch_uretprobe_is_alive() just returns "true".

      TODO: as documented by the previous change, arch_uretprobe_is_alive()
            can be fooled by sigaltstack/etc.

      uprobes/x86: Reimplement arch_uretprobe_is_alive()

      Add the x86 specific version of arch_uretprobe_is_alive()
      helper. It returns true if the stack frame mangled by
      prepare_uretprobe() is still on stack. So if it returns false,
      we know that the probed function has already returned.

      We add the new return_instance->stack member and change the
      generic code to initialize it in prepare_uretprobe, but it
      should be equally useful for other architectures.

      TODO: this assumes that the probed application can't use
            multiple stacks (say sigaltstack). We will try to improve
            this logic later.

      uprobes: Export 'struct return_instance', introduce 
arch_uretprobe_is_alive()

      Add the new "weak" helper, arch_uretprobe_is_alive(), used by
      the next patches. It should return true if this return_instance
      is still valid. The arch agnostic version just always returns
      true.

      The patch exports "struct return_instance" for the architectures
      which want to override this hook. We can also cleanup
      prepare_uretprobe() if we pass the new return_instance to
      arch_uretprobe_hijack_return_addr().

      uprobes: Change handle_trampoline() to find the next chain beforehand

      No functional changes, preparation.

      Add the new helper, find_next_ret_chain(), which finds the first
      !chained entry and returns its ->next. Yes, it is suboptimal. We
      probably want to turn ->chained into ->start_of_this_chain
      pointer and avoid another loop. But this needs the boring
      changes in dup_utask(), so lets do this later.

      Change the main loop in handle_trampoline() to unwind the stack
      until ri is equal to the pointer returned by this new helper.

      uprobes: Send SIGILL if handle_trampoline() fails

      1. It doesn't make sense to continue if handle_trampoline()
         fails, change handle_swbp() to always return after this call.

      2. Turn pr_warn() into uprobe_warn(), and change
         handle_trampoline() to send SIGILL on failure. It is pointless to
         return to user mode with the corrupted instruction_pointer() which
         we can't restore.

        - Simplify jiffies <-> usecs conversions. Remove dead code.

        - Remove early hacks on nohz full code that avoided messing up idle
          nohz internals. Now nohz integrates well full and idle and such hack
          have become needless.

        - Restart nohz full tick from irq exit. A simplification and a
          preparation for future optimization on scheduler kick to nohz full.

      ARM: zynq: reserve space for jump target in secondary trampoline

      Add a zero argument to the .word directive in
      zynq_secondary_trampoline.  Without an expression the assembler emits
      nothing for the .word directive.

      This makes it so that the intended range is communicated to ioremap
      and outer_flush_range in zynq_cpun_start; e.g. for LE
      trampoline_code_size evaluates to 12 now instead of 8.

      Found by inspection.  I'm not aware of any real problem this fixes.

      HID: sony: Fix DS4 controller reporting rate issues

      This commit removes the cap on the DualShock 4 controller reporting rate 
when
      connected using Bluetooth. The previous value of '0xB0' capped the rate 
to only
      20.83 Hz which many userspace utilities mistook as a sign of a bad signal.
      Since a 'B' and an '8' can look similar it's possible that someone 
mistook the
      one for another.  The new value of '0x80' enables the full 1000 Hz peak
      reporting rate that the controller is capable of.

      Frank adds: "Back when the original code was written the purpose of that 
value
      was unknown and 0xB0 seemed to work so that's what ended up being used.  
Now
      that we know what it actually does and that 0x80 is a better choice I 
support
      this patch."

      tipc: use temporary, non-protected skb queue for bundle reception

      Currently, when we extract small messages from a message bundle, or
      when many messages have accumulated in the link arrival queue, those
      messages are added one by one to the lock protected link input queue.
      This may increase contention with the reader of that queue, in
      the function tipc_sk_rcv().

      This commit introduces a temporary, unprotected input queue in
      tipc_link_rcv() for such cases. Only when the arrival queue has been
      emptied, and the function is ready to return, does it splice the whole
      temporary queue into the real input queue.

      tipc: remove implicit message delivery in node_unlock()

      After the most recent changes, all access calls to a link which
      may entail addition of messages to the link's input queue are
      postpended by an explicit call to tipc_sk_rcv(), using a reference
      to the correct queue.

      This means that the potentially hazardous implicit delivery, using
      tipc_node_unlock() in combination with a binary flag and a cached
      queue pointer, now has become redundant.

      This commit removes this implicit delivery mechanism both for regular
      data messages and for binding table update messages.

      tipc: make resetting of links non-atomic

      In order to facilitate future improvements to the locking structure, we
      want to make resetting and establishing of links non-atomic. I.e., the
      functions tipc_node_link_up() and tipc_node_link_down() should be called
      from outside the node lock context, and grab/release the node lock
      themselves. This requires that we can freeze the link state from the
      moment it is set to RESETTING or PEER_RESET in one lock context until
      it is set to RESET or ESTABLISHING in a later context. The recently
      introduced link FSM makes this possible, so we are now ready to introduce
      the above change.

      This commit implements this.

      tipc: merge link->exec_mode and link->state into one FSM

      Until now, we have been handling link failover and synchronization
      by using an additional link state variable, "exec_mode". This variable
      is not independent of the link FSM state, something causing a risk of
      inconsistencies, apart from the fact that it clutters the code.

      The conditions are now in place to define a new link FSM that covers
      all existing use cases, including failover and synchronization, and
      eliminate the "exec_mode" field altogether. The FSM must also support
      non-atomic resetting of links, which will be introduced later.

      The new link FSM is shown below, with 7 states and 8 events.
      Only events leading to state change are shown as edges.

      tipc: move protocol message sending away from link FSM

      The implementation of the link FSM currently takes decisions about and
      sends out link protocol messages. This is unnecessary, since such
      actions are not the result of any link state change, and are even
      decided based on non-FSM state information ("silent_intv_cnt").

      We now move the sending of unicast link protocol messages to the
      function tipc_link_timeout(), and the initial broadcast synchronization
      message to tipc_node_link_up(). The latter is done because a link
      instance should not need to know whether it is the first or second
      link to a destination. Such information is now restricted to and
      handled by the link aggregation layer in node.c

      tipc: move link synch and failover to link aggregation level

      Link failover and synchronization have until now been handled by the
      links themselves, forcing them to have knowledge about and to access
      parallel links in order to make the two algorithms work correctly.

      In this commit, we move the control part of this functionality to the
      link aggregation level in node.c, which is the right location for this.
      As a result, the two algorithms become easier to follow, and the link
      implementation becomes simpler.

      tipc: reverse call order for link_reset()->node_link_down()

      In many cases the call order when a link is reset goes as follows:
      tipc_node_xx()->tipc_link_reset()->tipc_node_link_down()

      This is not the right order if we want the node to be in control,
      so in this commit we change the order to:
      tipc_node_xx()->tipc_node_link_down()->tipc_link_reset()

      The fact that tipc_link_reset() now is called from only one
      location with a well-defined state will also facilitate later
      simplifications of tipc_link_reset() and the link FSM.

      tipc: move all link_reset() calls to link aggregation level

      In line with our effort to let the node level have full control over
      its links, we want to move all link reset calls from link.c to node.c.
      Some of the calls can be moved by simply moving the calling function,
      when this is the right thing to do. For the remaining calls we use
      the now established technique of returning a TIPC_LINK_DOWN_EVT
      flag from tipc_link_rcv(), whereafter we perform the reset call when
      the call returns.

      This change serves as a preparation for the coming commits.

      tipc: eliminate function tipc_link_activate()

      The function tipc_link_activate() is redundant, since it mostly performs
      settings that have already been done in a preceding tipc_link_reset().

      There are three exceptions to this:
      - The actual state change to TIPC_LINK_WORKING. This should anyway be done
        in the FSM, and not in a separate function.
      - Registration of the link with the bearer. This should be done by the
        node, since we don't want the link to have any knowledge about its
        specific bearer.
      - Call to tipc_node_link_up() for user access registration. With the new
        role distribution between link aggregation and link level this becomes
        the wrong call order; tipc_node_link_up() should instead be called
        directly as a result of a TIPC_LINK_UP event, hence by the node itself.

      This commit implements those changes.

      net/ipv6: add sysctl option accept_ra_min_hop_limit

      Commit 6fd99094de2b ("ipv6: Don't reduce hop limit for an interface")
      disabled accept hop limit from RA if it is smaller than the current hop
      limit for security stuff. But this behavior kind of break the RFC 
definition.

      RFC 4861, 6.3.4.  Processing Received Router Advertisements
         A Router Advertisement field (e.g., Cur Hop Limit, Reachable Time,
         and Retrans Timer) may contain a value denoting that it is
         unspecified.  In such cases, the parameter should be ignored and the
         host should continue using whatever value it is already using.

         If the received Cur Hop Limit value is non-zero, the host SHOULD set
         its CurHopLimit variable to the received value.

      So add sysctl option accept_ra_min_hop_limit to let user choose the 
minimum
      hop limit value they can accept from RA. And set default to 1 to meet RFC
      standards.

      PCI: Protect pci_bus->slots with pci_slot_mutex, not pci_bus_sem

      Rajat Jain reported a deadlock when PCIe hot-add and AER recovery happen 
at
      the same time:

      thread 1:

                          down_write(pci_bus_sem)        # deadlock here

      thread 2:

        aer_isr_one_error
          aer_process_err_device
            do_recovery
              broadcast_error_message(..., report_error_detected)

                  down_read(&pci_bus_sem)                # acquire pci_bus_sem
                  report_error_detected(dev)             # cb()
                    device_lock(dev)                     # deadlock here

      Previously, the bus->devices and bus->slots list were protected by
      pci_bus_sem.  In pci_create_slot(), we held it for writing so we could
      add to the bus->slots list.

      Add a new local pci_slot_mutex to protect bus->slots.  Hold pci_bus_sem 
for
      reading while searching the bus->devices list.

      iSCSI: let session recovery_tmo sysfs writes persist across recovery

      The iSCSI session recovery_tmo setting is writeable in sysfs, but it's
      also set every time a connection is established when parameters are set
      from iscsid over netlink.  That results in the timeout being reset to
      the default value after every recovery.

      The DM multipath tools want to use the sysfs interface to lower the
      default timeout when there are multiple paths to fail over.  It has
      caused confusion that we have a writeable sysfs value that seem to keep
      resetting itself.

      This patch adds an in-kernel flag that gets set once a sysfs write
      occurs, and then ignores netlink parameter setting once it's been
      modified via the sysfs interface.  My thinking here is that the sysfs
      interface is much simpler for external tools to influence the session
      timeout, but if we're going to allow it to be modified directly we
      should ensure that setting is maintained.

      Forward definition of 'hpet_clockevent' wasn't required and so it is
      placed after all the callback are defined, to avoid forward declaring
      all the callbacks.

      x86/lguest/timer: Migrate to new set-state interface

      Migrate lguest driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.

      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.

      We weren't doing anything while switching modes other than in shutdown
      mode and so those are not implemented.

      PCI/MSI: Free legacy IRQ when enabling MSI/MSI-X

      Once MSI/MSI-X is enabled by the device driver, a PCI device won't use
      legacy IRQs again until MSI/MSI-X is disabled.

      Call pcibios_free_irq() when enabling MSI/MSI-X and pcibios_alloc_irq()
      when disabling MSI/MSI-X.  This allows arch code to manage resources
      associated with the legacy IRQ.

      ARM64: PCI: do not enable resources on PROBE_ONLY systems

      On ARM64 PROBE_ONLY PCI systems resources are not currently claimed,
      therefore they can't be enabled since they do not have a valid
      parent pointer; this in turn prevents enabling PCI devices on
      ARM64 PROBE_ONLY systems, causing PCI devices initialization to
      fail.

      To solve this issue, resources must be claimed when devices are
      added on PROBE_ONLY systems, which ensures that the resource hierarchy
      is validated and the resource tree is sane, but this requires changes
      in the ARM64 resource management that can affect adversely existing
      PCI set-ups (claiming resources on !PROBE_ONLY systems might break
      existing ARM64 PCI platform implementations).

      As a temporary solution in preparation for a proper resources claiming
      implementation in ARM64 core, to enable PCI PROBE_ONLY systems on ARM64,
      this patch adds a pcibios_enable_device() arch implementation that
      simply prevents enabling resources on PROBE_ONLY systems (mirroring ARM
      behaviour).

      This is always a safe thing to do because on PROBE_ONLY systems the
      configuration space set-up can be considered immutable, and it is in
      preparation of proper resource claiming that would finally validate
      the PCI resources tree in the ARM64 arch implementation on PROBE_ONLY
      systems.

      For !PROBE_ONLY systems resources enablement in pcibios_enable_device()
      on ARM64 is implemented as in current PCI core, leaving the behaviour
      unchanged.

      arm64: cmpxchg: truncate sub-word signed types before comparison

      When performing a cmpxchg operation on a signed sub-word type (e.g. s8),
      we need to ensure that the upper register bits of the "old" value used
      for comparison are zeroed, otherwise we may erroneously fail the cmpxchg
      which may even be interpreted as success by the caller (if the compiler
      performs the truncation as part of its check). This has been observed
      in mod_state, where negative values where causing problems with
      this_cpu_cmpxchg.

      This patch fixes the issue by explicitly casting 8-bit and 16-bit "old"
      values using unsigned types in our cmpxchg wrappers. 32-bit types can be
      left alone, since the underlying asm makes use of W registers in this
      case.

      bpf: provide helper that indicates eBPF was migrated

      During recent discussions we had with Michael, we found that it would
      be useful to have an indicator that tells the JIT that an eBPF program
      had been migrated from classic instructions into eBPF instructions, as
      only in that case A and X need to be cleared in the prologue. Such eBPF
      programs do not set a particular type, but all have BPF_PROG_TYPE_UNSPEC.
      Thus, introduce a small helper for cde66c2d88da ("s390/bpf: Only clear
      A and X for converted BPF programs") and possibly others in future.

      test_bpf: assign type to native eBPF test cases

      As JITs start to perform optimizations whether to clear A and X on eBPF
      programs in the prologue, we should actually assign a program type to the
      native eBPF test cases. It doesn't really matter which program type, as
      these instructions don't go through the verifier, but it needs to be a
      type != BPF_PROG_TYPE_UNSPEC. This reflects eBPF programs loaded via 
bpf(2)
      system call (!= type unspec) vs. classic BPF to eBPF migrations (== type
      unspec).

      arm64: alternative: put secondary CPUs into polling loop during patch

      When patching the kernel text with alternatives, we may end up patching
      parts of the stop_machine state machine (e.g. atomic_dec_and_test in
      ack_state) and consequently corrupt the instruction stream of any
      secondary CPUs.

      This patch passes the cpu_online_mask to stop_machine, forcing all of
      the CPUs into our own callback which can place the secondary cores into
      a dumb (but safe!) polling loop whilst the patching is carried out.

      Input: touchscreen - export OF module alias information

      The I2C core always reports the MODALIAS uevent as "i2c:<client name"
      regardless if the driver was matched using the I2C id_table or the
      of_match_table. So technically there's no need for a driver to export
      the OF table since currently it's not used.

      In fact, the I2C device ID table is mandatory for I2C drivers since
      a i2c_device_id is passed to the driver's probe function even if the
      I2C core used the OF table to match the driver.

      And since the I2C core uses different tables, OF-only drivers needs to
      have duplicated data that has to be kept in sync and also the dev node
      compatible manufacturer prefix is stripped when reporting the MODALIAS.

      To avoid the above, the I2C core behavior may be changed in the future
      to not require an I2C device table for OF-only drivers and report the
      OF module alias. So, it's better to also export the OF table to prevent
      breaking module autoloading if that happens.

      This is determined by the audio bandwidth constraints of the endpoint.

      In current code, the wMaxPacketSize is defined as the maximum packet size
      for ISO endpoint, and it will let the host reserve much more space than
      it really needs, so that we can't let more endpoints work together at
      one frame.

      We find this issue when we try to let 4 f_uac2 gadgets work together [1]
      at FS connection.

      usb: dwc3: ep0: Fix mem corruption on OUT transfers of more than 512 bytes

      DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and
      the size of bounce buffer is 512 bytes. However if the host initiates OUT
      transfers of size more than 512 bytes (and non max packet aligned), the
      driver throws a WARN dump but still programs the TRB to receive more than
      512 bytes. This will cause bounce buffer to overflow and corrupt the
      adjacent memory locations which can be fatal.

      Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE
      (512) bytes.

      USB: pl2303: fix baud-rate divisor calculations

      This commit fixes the following issues:

      1. The 9th bit of buf was believed to be the LSB of divisor's
      exponent, but the hardware interprets it as MSB (9th bit) of the
      mantissa. The exponent is actually one bit shorter and applies
      to base 4, not 2 as previously believed.

      2. Loop iterations doubled the exponent instead of incrementing.

      3. The exponent wasn't checked for overflow.

      4. The function returned requested rate instead of actual rate.

      Due to issue #2, the old code deviated from the wrong formula
      described in #1 and actually yielded correct rates when divisor
      was lower than 4096 by using exponents of 0, 2 or 4 base-2,
      interpreted as 0, 1, 2 base-4 with the 9th mantissa bit clear.
      However, at 93.75 kbaud or less the rate turned out too slow
      due to #2 or too fast due to #2 and #3.

      I tested this patch by sending and validating 0x00,0x01,..,0xff
      to an FTDI dongle at 234, 987, 2401, 9601, 31415, 115199, 250k,
      500k, 750k, 1M, 1.5M, 3M+1 baud. All rates passed.

      I also used pv to check speed at some rates unsupported by FTDI:
      45 (the lowest possible), 2M, 4M, 5M and 6M-1. Looked sane.

      ath10k: initialize msdu ext. descriptor before use

      Initial QCA99X0 support has a known issue with TCP Tx throughput.
      All other path such as UDP Tx/Rx and TCP Rx meet their expectation
      (> 900Mbps), but TCP Tx marked as low as 5Mbps when single pair is
      used on iperf.

      The root cause is turned out because TSO flag is not initialized
      properly so that firmware configures TSO in wrong way.
      TSO flags in msdu extension descriptor is required to be reset
      to indicate firmware there is no TSO is enabled, otherwise it
      could act as TSO is enabled which causes huge throughput drop.

      In fact, it's enough by resetting TSO flags only to prevent the
      unexpected behavior, but initializing whole msdu ext. descriptor
      will help to clear uncertainty of firmware could bring on as it
      constantly updated.

      ath10k: fix memory alloc failure in qca99x0 during wmi svc rdy event

      Host memory required for firmware is allocated while handling
      wmi service ready event. Right now, wmi service ready is handled
      in tasklet context and it calls dma_alloc_coherent() with atomic
      flag (GFP_ATOMIC) to allocate memory in host needed for firmware.
      The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in
      the platform (at least in AP platform) where it has less atomic
      pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory
      for one card, having additional QCA99X0 card in the same platform
      will require similarly amount of memory. So, it's not guaranteed that
      all the platform will have enough atomic memory pool.

      Fix this issue, by handling wmi service ready event in workqueue
      context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work
      queue will not be ready at the time of handling wmi service ready.
      So, it can't be used to handle wmi service ready. Also, register work
      gets scheduled during insmod in existing ath10k_wq and waits for
      wmi service ready to completed. Both workqueue can't be used for
      this purpose. New auxiliary workqueue is added to handle wmi service
      ready.

      MAINTAINERS: change 842 NX owner email address

      Change my IBM email to my personal IEEE email.

      I'm leaving IBM, so my email there won't work anymore.  This changes
      the owner to my personal email, so I can still get cc'ed on patches,
      until someone at IBM sends a patch to take it over.

      One of the debug messages in the NX 842 PowerNV driver is missing
      the required be32_to_cpu() wrapper when accessing the __be32 field
      csb->count.  Add the wrapper so the message will show the correct count.

      crypto: nx - don't err if compressed output > input

      Return success instead of error if compression succeeds but the output is
      larger than the input.

      It's unlikely that the caller will use the compressed data since it's
      larger than the original uncompressed data, but there was no error and
      returning an error code is incorrect.  Further, for testing small input
      buffers, the output is likely to be larger than the input and success
      needs to be returned to verify the test.

      mac802154: Fix memory corruption with global deferred transmit state.

      When transmitting a packet via a mac802154 driver that can sleep in
      its transmit function, mac802154 defers the call to the driver's
      transmit function to a per-device workqueue.

      However, mac802154 uses a single global work_struct for this, which
      means that if you have more than one registered mac802154 interface
      in the system, and you transmit on more than one of them at the same
      time, you'll very easily cause memory corruption.

      This patch moves the deferred transmit processing state from global
      variables to struct ieee802154_local, and this seems to fix the memory
      corruption issue.

      Bluetooth: btusb: match generic class code in interface descriptor

      btusb currently has a generic match on USB device descriptors:
              { USB_DEVICE_INFO(0xe0, 0x01, 0x01) },

      However, http://www.usb.org/developers/defined_class states:

        Base Class E0h (Wireless Controller)
        This base class is defined for devices that are Wireless controllers.
        Values not shown in the table below are reserved. These class codes are
        to be used in Interface Descriptors, with the exception of the Bluetooth
        class code which can also be used in a Device Descriptor.

      Add a match on the interface descriptors accordingly.

      This fixes compatibility with the RTL8723AU device shown below.
      This device conforms to the USB Interface Association Descriptor
      specification, which requires the device to have class ef/02/01.
      The extra IAD descriptor then specifies that interfaces 0 and 1
      belong to the same function/driver, which is true. Provided that
      the Bluetooth device class spec accepts use of the IAD, I imagine that
      technically, all btusb devices should be configured like this.

      netfilter: nf_ct_sctp: minimal multihoming support

      Currently nf_conntrack_proto_sctp module handles only packets between
      primary addresses used to establish the connection. Any packets between
      secondary addresses are classified as invalid so that usual firewall
      configurations drop them. Allowing HEARTBEAT and HEARTBEAT-ACK chunks to
      establish a new conntrack would allow traffic between secondary
      addresses to pass through. A more sophisticated solution based on the
      addresses advertised in the initial handshake (and possibly also later
      dynamic address addition and removal) would be much harder to implement.
      Moreover, in general we cannot assume to always see the initial
      handshake as it can be routed through a different path.

      The patch adds two new conntrack states:

        SCTP_CONNTRACK_HEARTBEAT_SENT  - a HEARTBEAT chunk seen but not acked
        SCTP_CONNTRACK_HEARTBEAT_ACKED - a HEARTBEAT acked by HEARTBEAT-ACK

      State transition rules:

      - HEARTBEAT_SENT responds to usual chunks the same way as NONE (so that
        the behaviour changes as little as possible)
      - HEARTBEAT_ACKED responds to usual chunks the same way as ESTABLISHED
        does, except the resulting state is HEARTBEAT_ACKED rather than
        ESTABLISHED
      - previously existing states except NONE are preserved when HEARTBEAT or
        HEARTBEAT-ACK is seen
      - NONE (in the initial direction) changes to HEARTBEAT_SENT on HEARTBEAT
        and to CLOSED on HEARTBEAT-ACK
      - HEARTBEAT_SENT changes to HEARTBEAT_ACKED on HEARTBEAT-ACK in the
        reply direction
      - HEARTBEAT_SENT and HEARTBEAT_ACKED are preserved on HEARTBEAT and
        HEARTBEAT-ACK otherwise

      Normally, vtag is set from the INIT chunk for the reply direction and
      from the INIT-ACK chunk for the originating direction (i.e. each of
      these defines vtag value for the opposite direction). For secondary
      conntracks, we can't rely on seeing INIT/INIT-ACK and even if we have
      seen them, we would need to connect two different conntracks. Therefore
      simplified logic is applied: vtag of first packet in each direction
      (HEARTBEAT in the originating and HEARTBEAT-ACK in reply direction) is
      saved and all following packets in that direction are compared with this
      saved value. While INIT and INIT-ACK define vtag for the opposite
      direction, vtags extracted from HEARTBEAT and HEARTBEAT-ACK are always
      for their direction.

      Default timeout values for new states are

        HEARTBEAT_SENT: 30 seconds (default hb_interval)
        HEARTBEAT_ACKED: 210 seconds (hb_interval * path_max_retry + max_rto)

      (We cannot expect to see the shutdown sequence so that, unlike
      ESTABLISHED, the HEARTBEAT_ACKED timeout shouldn't be too long.)

      Introduce Mellanox Technologies Switch ASICs switchdev drivers

      This patchset introduces Mellanox Technologies Switch driver 
infrastructure
      and support for SwitchX-2 ASIC.

      The driver is divided into 3 logical parts:
      1) Bus - implements switch bus interface. Currently only PCI bus is
         implemented, but more buses will be added in the future. Namely I2C
         and SGMII.
         (patch #2)
      2) Driver - implemements of ASIC-specific functions.
         Currently SwitchX-2 ASIC is supported, but a plan exists to introduce
         support for Spectrum ASIC in the near future.
         (patch #4)
      3) Core - infrastructure that glues buses and drivers together.
         It implements register access logic (EMADs) and takes care of RX traps
         and events.
         (patch #1 and #3)

      mlxsw: Add interface to access registers and process events

      Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
      the host and the device in order to configure the available device 
registers.
      Another use case is notifications sent from the device to the host,
      letting it know about certain events, such as port up / down.

      Add the ability to construct EMADs with provisions to construct and
      parse the registers' payloads. Implement EMAD transaction layer
      which is responsible for the reliable transmission of EMADs. Also, add
      an infrastructure used by the switch driver to register for particular
      events generated by the device.

      mlxsw: Introduce Mellanox switch driver core

      Add core components of Mellanox switch driver infrastructure.
      Core infrastructure is designed so that it can be used by multiple
      bus drivers (PCI now, I2C and SGMII are planned to be implemented
      in the future). Multiple switch kind drivers can be registered as well.
      This core serves as a glue between buses and drivers.

      bnx2x: add vlan filtering offload

      Current driver always uses vlan-promisc mode, i.e., it receives both
      tagged and untagged traffic and lets the network stack drop packets
      tagged with unrequested vlan tags.

      This patch implements vlan-filtering offload in the driver -
      Unless explicitly configured to promisc mode, only untagged packets or
      packets tagged with requested vlans would reach the Rx flow.

      net/mlx5e: Remove the mlx5e_update_priv_params() function

      It was used to update netdev priv parameters that require stopping
      and re-opening the device in a generic way - it got the new
      parameters and did: ndo_stop(), copy new parameters into current
      parameters, ndo_open().

      We chose to remove it for two reasons:
      1) It requires additional instance of struct mlx5e_params on the
         stack and looking forward we expect this struct to grow.
      2) Sometimes we want to do additional operations (besides
         just updating the priv parameters) while the netdev is stopped.
         For example, updating netdev->mtu @mlx5e_change_mtu() should
         be done while the netdev is stopped (done in this commit).

      gianfar: Fix warnings when built on 64-bit

      As part of defconfig consolidation using fragments, we'd like to be
      able to have the same drivers enabled on 32-bit and 64-bit.  Gianfar
      happens to only exist on 32-bit systems, and when building the
      resulting 64-bit kernel warnings were produced.

      A couple of the warnings are trivial, but the rfbptr code has deeper
      issues.  It uses the virtual address as the DMA address, which again,
      happens to work in the environments where this driver is currently
      used, but is not the right thing to do.

      changing the sk_txhash in that function. This provides a rudimentary

      powerpc/kernel: Enable seccomp filter

      This commit enables seccomp filter on powerpc, now that we have all the
      necessary pieces in place.

      To support seccomp's desire to modify the syscall return value under
      some circumstances, we use a different ABI to the ptrace ABI. That is we
      use r3 as the syscall return value, and orig_gpr3 is the first syscall
      parameter.

      This means the seccomp code, or a ptracer via SECCOMP_RET_TRACE, will
      see -ENOSYS preloaded in r3. This is identical to the behaviour on x86,
      and allows seccomp or the ptracer to either leave the -ENOSYS or change
      it to something else, as well as rejecting or not the syscall by
      modifying r0.

      If seccomp does not reject the syscall, we restore the register state to
      match what ptrace and audit expect, ie. r3 is the first syscall
      parameter again. We do this restore using orig_gpr3, which may have been
      modified by seccomp, which allows seccomp to modify the first syscall
      paramater and allow the syscall to proceed.

      We need to #ifdef the the additional handling of r3 for seccomp, so move
      it all out of line.

      net: netcp: Fixes efuse mac addr swap on k2e and k2l

      On some of the K2E and K2L platforms, the two DWORDs in
      efuse occupied by the pre-programmed mac address for
      slave port 1 are swapped.  To workaround this issue,
      this patch adds a new define NETCP_EFUSE_ADDR_SWAP (2)
      which signifies the occurrence of such swapping so that
      the driver can take proper action.  The flag can be
      enabled in the corresponding netcp interface dts binding
      as efuse-mac = <2>  under the corresponding netcp
      interface node.

      tipc: fix bug in broadcast synch message create function

      In commit d999297c3dbbe7fdd832f7fa4ec84301e170b3e6
      ("tipc: reduce locking scope during packet reception") we introduced
      a new function tipc_build_bcast_sync_msg(), which carries initial
      synchronization data between two nodes at first contact and at
      re-contact. In this function, we missed to add synchronization data,
      with the effect that the broadcast link endpoints will fail to
      synchronize correctly at re-contact between a running and a restarted
      node. All other cases work as intended.

      With this commit, we fix this bug.

      irqchip/gicv3-its: Split PCI/MSI code from the core ITS driver

      It is becoming obvious that having the PCI/MSI code in the same
      file as the the core ITS code is giving people implementing non-PCI
      MSI support the wrong kind of idea.

      In order to make things a bit clearer, let's move the PCI/MSI code
      out to its own file. Hopefully it will make it clear that whoever
      thinks of hooking into the core ITS better have a very strong point.

      We use a temporary entry point that will get removed in a subsequent
      patch, once the proper infrastructure is added.

      Some IRQ domains are not designed to directly provide interrupts
      to devices, but strictly to be used by other domains. An example
      of this is the GICv3 ITS, which is completely bus agnostic, and
      on which it is possible to implement a PCI/MSI domain.

      drivers/base: Add MSI domain support for non-PCI devices

      With the msi_list and the msi_domain properties now being at the
      generic device level, it is starting to be relatively easy to offer
      a generic way of providing non-PCI MSIs.

      The two major hurdles with this idea are:

      - Lack of global ID that identifies a device: this is worked around by
        having a global ID allocator for each device that gets enrolled in
        the platform MSI subsystem

      - Lack of standard way to write the message in the generating device.
        This is solved by mandating driver code to provide a write_msg
        callback, so that everyone can have their own square wheel

      Apart from that, the API is fairly straightforward:

      - platform_msi_create_irq_domain creates an MSI domain that gets
        tagged with DOMAIN_BUS_PLATFORM_MSI

      - platform_msi_domain_alloc_irqs allocate MSIs for a given device,
        populating the msi_list

      - platform_msi_domain_free_irqs does what is written on the tin

      [ tglx: Created a seperate struct platform_msi_desc and added
                kerneldoc entries ]

      PCI/MSI: Let pci_msi_get_domain use struct device::msi_domain

      Now that we can easily find which MSI domain a PCI device is
      using, use dev_get_msi_domain as a way to retrieve the information.

      The original code is still used as a fallback.

      PCI/MSI: Allow msi_domain lookup using the host bridge node

      A number of platforms do not need to use the msi-parent property,
      as the host bridge itself provides the MSI controller.

      Allow this configuration by performing an irq domain lookup based
      on the host bridge node if it doesn't have a valid msi-parent property.

      In order to populate the PCI host bridge msi_domain, use the
      "msi-parent" attribute to lookup a corresponding irq domain.
      If found, this is our MSI domain.

      This gets plugged into the core PCI code.

      device core: Introduce per-device MSI domain pointer

      As MSI-type features are creeping into non-PCI devices, it is
      starting to make sense to give our struct device some form of
      support for this, by allowing a pointer to an MSI irq domain to
      be set/retrieved.

      genirq/irqdomain: Allow irq domain aliasing

      It is not uncommon (at least with the ARM stuff) to have a piece
      of hardware that implements different flavours of "interrupts".
      A typical example of this is the GICv3 ITS, which implements
      standard PCI/MSI support, but also some form of "generic MSI".

      So far, the PCI/MSI domain is registered using the ITS device_node,
      so that irq_find_host can return it. On the contrary, the raw MSI
      domain is not registered with an device_node, making it impossible
      to be looked up by another subsystem (obviously, using the same
      device_node twice would only result in confusion, as it is not
      defined which one irq_find_host would return).

      A solution to this is to "type" domains that may be aliasing, and
      to be able to lookup an device_node that matches a given type.
      For this, we introduce irq_find_matching_host() as a superset
      of irq_find_host:

      struct irq_domain *irq_find_matching_host(struct device_node *node,
                                      enum irq_domain_bus_token bus_token);

      where bus_token is the "type" we want to match the domain against
      (so far, only DOMAIN_BUS_ANY is defined). This result in some
      moderately invasive changes on the PPC side (which is the only
      user of the .match method).

      This has otherwise no functionnal change.

      This data is cached by s390 JIT to improve performance of ld_abs/ld_ind
      instructions. Therefore after a change we have to reload the data.

      In case of usage of skb_vlan_push/pop, in the prologue we store

      to skb_vlan_push/pop.

      The 20 bit displacements are available since z990 and BPF requires

      s390/bpf: Fix multiple macro expansions

      The EMIT6_DISP_LH macro passes the "disp" parameter to the _EMIT6_DISP_LH
      macro. The _EMIT6_DISP_LH macro uses the "disp" parameter twice:

       unsigned int __disp_h = ((u32)disp) & 0xff000;
       unsigned int __disp_l = ((u32)disp) & 0x00fff;

      The EMIT6_DISP_LH is used several times with EMIT_CONST_U64() as "disp"
      parameter. Therefore always two constants are created per usage of
      EMIT6_DISP_LH.

      Fix this and add variable "_disp" to avoid multiple expansions.

      * v2: Move "_disp" to _EMIT6_DISP_LH as suggested by Joe Perches

      PCI: iproc: enable arm64 support for iProc PCIe

      PCI: iproc: Add arm64 support

      Add arm64 support to the iProc PCIe driver.

      Note that on arm32, bus->sysdata points to the arm32-specific
      pci_sys_data struct, and pci_sys_data.private_data contains the
      iproc_pcie pointer. For arm64, there's nothing corresponding to
      pci_sys_data, so we keep the iproc_pcie pointer directly in
      bus->sysdata.

      In addition, arm64 does IRQ mapping in pcibios_add_device(), so it
      doesn't need pci_fixup_irqs() as arm32 does.

      x86/pci/intel_mid_pci: Work around for IRQ0 assignment

      On Intel Tangier the MMC host controller is wired up to irq 0. But
      several other devices have irq 0 associated as well due to a bogus PCI
      configuration.

      The first initialized driver will acquire irq 0 and make it
      unavailable for other devices. If the sdhci driver is not the first
      one it will fail to acquire the interrupt and therefor be non
      functional.

      Add a quirk to the pci irq enable function which denies irq 0 to
      anything else than the MMC host controller driver on Tangier
      platforms.

      perf tools: Force period term to overload global settings

      Currently the command line option settings beats the per event period
      settings:

      With no global settings, we get per-event configuration:

        $ perf record -e 'cpu/instructions,period=20000/' sleep 1
        $ perf evlist -v
        ... { sample_period, sample_freq }: 20000 ...

      With 'c' option period setup, we get 'c' option value:
        $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
        $ perf evlist -v
        ... { sample_period, sample_freq }: 1000 ...

      This patch makes the per-event settings overload the global 'c' option
      setup:

        $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
        $ perf evlist -v
        ... { sample_period, sample_freq }: 20000 ...

      I think the making the per-event settings to overload any other config
      makes more sense than current state. However it breaks the current
      'period' term handling, which might cause some noise.. so let's see ;-).

      Also fixing parse event tests with the new behaviour.

      spi: bcm2835: set up spi-mode before asserting cs-gpio

      When using reverse polarity for clock (spi-cpol) on a device
      the clock line gets altered after chip-select has been asserted
      resulting in an additional clock beat, which confuses hardware.

      This did not show when using native-CS, as the same register
      is used to control cs as well as polarity, so the changes came
      into effect at the same time. Unfortunately this is not true
      with gpio-cs.

      To avoid this situation this patch moves the setup of polarity
      (spi-cpol and spi-cpha) outside of the chip-select into
      prepare_message, which is run prior to asserting chip-select.

      Also fixes resetting 3-wire mode after use of rx-mode, so that
      a 3-Wire sequence TX, RX, TX works as well (right now it runs
      TX, RX, RX instead)

      perf session env: Rename exit method

      The semantic associated in tools/perf/ with foo__delete(instance) is to
      release all resources referenced by 'instance' members and then release
      the memory for 'instance' itself.

      The perf_session_env__delete() function isn't doing this, it just does
      the first part, but the space used by 'instance' itself isn't freed, as
      it is embedded in a larger structure, that will be freed at other stage.

      For these cases we se foo__exit(), i.e. the usage is:

       void foo__delete(foo)
       {
               if (foo) {
                       foo__exit(foo);
                       free(foo);
               }
       }

      But when we have something like:

       struct bar {
               struct foo foo;
               . . .
       }

      Then we can't really call foo__delete(&bar.foo), we must have this
      instead:

       void bar__exit(bar)
       {
               foo__exit(&bar.foo);
               /* free other bar-> resources */
       }

       void bar__delete(bar)
       {
               if (bar) {
                bar__exit(bar);
                      free(bar);
               }
       }

      So just rename perf_session_env__delete() to perf_session_env__exit().

      btrfs: add missing discards when unpinning extents with -o discard

      When we clear the dirty bits in btrfs_delete_unused_bgs for extents
      in the empty block group, it results in btrfs_finish_extent_commit being
      unable to discard the freed extents.

      The block group removal patch added an alternate path to forget extents
      other than btrfs_finish_extent_commit.  As a result, any extents that
      would be freed when the block group is removed aren't discarded.  In my
      test run, with a large copy of mixed sized files followed by removal, it
      left nearly 2/3 of extents undiscarded.

      btrfs: explictly delete unused block groups in close_ctree and ro-remount

      The cleaner thread may already be sleeping by the time we enter
      close_ctree.  If that's the case, we'll skip removing any unused
      block groups queued for removal, even during a normal umount.
      They'll be cleaned up automatically at next mount, but users
      expect a umount to be a clean synchronization point, especially
      when used on thin-provisioned storage with -odiscard.  We also
      explicitly remove unused block groups in the ro-remount path
      for the same reason.

      btrfs: iterate over unused chunk space in FITRIM

      Since we now clean up block groups automatically as they become
      empty, iterating over block groups is no longer sufficient to discard
      unused space.

      This patch iterates over the unused chunk space and discards any regions
      that are unallocated, regardless of whether they were ever used.  This is
      a change for btrfs but is consistent with other file systems.

      We do this in a transactionless manner since the discard process can take
      a substantial amount of time and a transaction would need to be started
      before the acquisition of the device list lock.  That would mean a
      transaction would be held open across /all/ of the discards collectively.
      In order to prevent other threads from allocating or freeing chunks, we
      hold the chunks lock across the search and discard calls.  We release it
      between searches to allow the file system to perform more-or-less
      normally.  Since the running transaction can commit and disappear while
      we're using the transaction pointer, we take a reference to it and
      release it after the search.  This is safe since it would happen normally
      at the end of the transaction commit after any locks are released anyway.
      We also take the commit_root_sem to protect against a transaction starting
      and committing while we're running.

      btrfs: skip superblocks during discard

      Btrfs doesn't track superblocks with extent records so there is nothing
      persistent on-disk to indicate that those blocks are in use.  We track
      the superblocks in memory to ensure they don't get used by removing them
      from the free space cache when we load a block group from disk.  Prior
      to 47ab2a6c6a (Btrfs: remove empty block groups automatically), that
      was fine since the block group would never be reclaimed so the superblock
      was always safe.  Once we started removing the empty block groups, we
      were protected by the fact that discards weren't being properly issued
      for unused space either via FITRIM or -odiscard.  The block groups were
      still being released, but the blocks remained on disk.

      In order to properly discard unused block groups, we need to filter out
      the superblocks from the discard range.  Superblocks are located at fixed
      locations on each device, so it makes sense to filter them out in
      btrfs_issue_discard, which is used by both -odiscard and FITRIM.

      btrfs: btrfs_issue_discard ensure offset/length are aligned to sector 
boundaries

      It's possible, though unexpected, to pass unaligned offsets and lengths
      to btrfs_issue_discard.  We then shift the offset/length values to sector
      units.  If an unaligned offset has been passed, it will result in the
      entire sector being discarded, possibly losing data.  An unaligned
      length is safe but we'll end up returning an inaccurate number of
      discarded bytes.

      This patch aligns the offset to the 512B boundary, adjusts the length,
      and warns, since we shouldn't be discarding on an offset that isn't
      aligned with our sector size.

      The A31 SoC uses the same musb controller as found in earlier SoCs, but it
      is hooked up slightly different. Its SRAM is private and no longer 
controlled
      through the SRAM controller, and its reset is controlled via a separate
      reset controller. This commit adds support for this setup.

      usb: musb: sunxi: Add support for the Allwinner sunxi musb controller

      This is based on initial code to get the Allwinner sunxi musb controller
      supported by Chen-Yu Tsai and Roman Byshko.

      This adds support for the Allwinner sunxi musb controller in both host 
only
      and otg mode. Peripheral only mode is not supported, as no boards use 
that.

      This has been tested on a cubietruck (A20 SoC) and an UTOO P66 tablet
      (A13 SoC) with a variety of devices in host mode and with the g_serial 
gadget
      driver in peripheral mode, plugging otg / host cables in/out a lot of 
times
      in all possible imaginable plug orders.

      usb: composite: add bind_deactivated flag to usb_function

      This patch introduces 'bind_deactivated' flag in struct usb_function.
      Functions which don't want to be activated automatically after bind should
      set this flag, and when they start to be ready to work they should call
      usb_function_activate().

      When USB function sets 'bind_deactivated' flag, initial deactivation
      counter is incremented automatically, so there is no need to call
      usb_function_deactivate() in function bind.

      Using usb_gadget_disconnect to make gadget temporarily invisible to host
      doesn't provide desired result, because gadget is connected immediately
      after binding regardless to previous usb_gadget_disconnect() calls.

      usb: dwc3: core: remove unnecessary dev_warn()

      When a SoC supports both PHY interfaces but
      doesn't define HSPHY in DT/pdata, we will get
      an unnecessary dev_warn() which can mislead users
      into thinking that they're missing something.

      Instead, let's just silently rely on a correct
      default. If the HW default is wrong, then HSPHY
      is required and USB won't work, this will be
      motivation enough for engineers to patch their
      way into a working setup.

      Use this additional parameter and the _optional variant to simplify the

      why it's not sensible to switch to devm_gpiod_get and why the gpiod_put
      is also necessary.

      Furthermore this is one caller less that stops us making the flags

      This patch adds removable mass storage support to g_nokia gadget (for 
N900).
      It means that at runtime block device can be exported or unexported.
      So it does not export anything by default and thus allows to use MyDocs
      partition as before...

      block: shrink struct bio down to 2 cache lines again

      Commit bcf2843b3f8f added ->bi_error to cleanup the error passing
      for struct bio, but that ended up adding 4 bytes and a 4 byte hole
      to the size of struct bio. For a clean config, that bumped it from
      128 bytes, to 136 bytes, on x86-64.

      The ->bi_flags member is currently an unsigned long, but it fits
      easily within an int. Change it to an unsigned int, adjust the
      the pool offset code, and move ->bi_error into the new hole. Then
      we end up with a 128 byte bio again.

      Change the bio flag set/clear to use cmpxchg to ensure we don't
      lose any flags when manipulating them.

      block: manipulate bio->bi_flags through helpers

      Some places use helpers now, others don't. We only have the 'is set'
      helper, add helpers for setting and clearing flags too.

      It was a bit of a mess of atomic vs non-atomic access. With
      BIO_UPTODATE gone, we don't have any risk of concurrent access to the
      flags. So relax the restriction and don't make any of them atomic. The
      flags that do have serialization issues (reffed and chained), we
      already handle those separately.

      block: add a bi_error field to struct bio

      Currently we have two different ways to signal an I/O error on a BIO:

       (1) by clearing the BIO_UPTODATE flag
       (2) by returning a Linux errno value to the bi_end_io callback

      The first one has the drawback of only communicating a single possible
      error (-EIO), and the second one has the drawback of not beeing persistent
      when bios are queued up, and are not passed along from child to parent
      bio in the ever more popular chaining scenario.  Having both mechanisms
      available has the additional drawback of utterly confusing driver authors
      and introducing bugs where various I/O submitters only deal with one of
      them, and the others have to add boilerplate code to deal with both kinds
      of error returns.

      So add a new bi_error field to store an errno value directly in struct
      bio and remove the existing mechanisms to clean all this up.

      Use regmap helpers for get_voltage_sel and set_voltage_sel ops

      The DVS GPIO allows on the fly selection of the VSEL register
      from two choices. However, if it is not set, the VSEL register
      will stay fixed and we can use the regmap ops. This allows use

      perf python: Remove dependency on 'machine' methods

      The python binding still doesn't provide symbol resolving facilities,
      but the recent addition of the trace_event__register_resolver() function
      made it add as a dependency the machine__resolve_kernel_addr() method,
      that in turn drags all the symbol resolving code.

      The problem:

        [root@zoo ~]# perf test -v python
        17: Try 'import perf' in python, checking link problems      :
        --- start ---
        test child forked, pid 6853
        Traceback (most recent call last):
          File "<stdin>", line 1, in <module>
        ImportError: /tmp/build/perf/python/perf.so: undefined symbol: 
machine__resolve_kernel_addr
        test child finished with -1
        ---- end ----
        Try 'import perf' in python, checking link problems: FAILED!
        [root@zoo ~]#

      Fix it by requiring this function to receive the resolver as a
      parameter, just like pevent_register_function_resolver(), i.e. do
      not explicitely refer to an object file not included in
      tools/perf/util/python-ext-sources.

        [root@zoo ~]# perf test python

      nohz: Restart nohz full tick from irq exit

      Restart the tick when necessary from the irq exit path. It makes nohz
      full more flexible, simplify the related IPIs and doesn't bring
      significant overhead on irq exit.

      In a longer term view, it will allow us to piggyback the nohz kick
      on the scheduler IPI in the future instead of sending a dedicated IPI
      that often doubles the scheduler IPI on task wakeup. This will require
      more changes though including careful review of resched_curr() callers
      to include nohz full needs.

      nohz: Remove idle task special case

      On nohz full early days, idle dynticks and full dynticks weren't well
      integrated and we couldn't risk full dynticks calls on idle without
      risking messing up tick idle statistics. This is why we prevented such
      thing to happen.

      Nowadays full dynticks and idle dynticks are better integrated and
      interact without known issue.

      So lets remove that.

      nohz: Prevent tilegx network driver interrupts

      Normally the tilegx networking shim sends irqs to all the cores
      to distribute the load of processing incoming-packet interrupts,
      so that you can get to multiple Gb's of traffic inbound.

      However, in nohz_full mode we don't want to interrupt the
      nohz_full cores by default, so we limit the set of cores we use
      to only the online housekeeping cores.

      To make client code easier to read, we introduce a new nohz_full
      accessor, housekeeping_cpumask(), which returns a pointer to the
      housekeeping_mask if nohz_full is enabled, and otherwise returns
      the cpu_possible_mask.

      ASoC: dapm: Simplify list creation in dapm_dai_get_connected_widgets()

      When running dapm_dai_get_connected_widgets() currently in
      is_connected_{input,output}_ep() for each widget that gets added the array
      is resized and the code also loops over all existing entries to avoid
      adding a widget multiple times.

      The former can be avoided by collecting the widgets in a linked list and
      only once we have all widgets allocate the array.

      The later can be avoided by changing when the widget is added. Currently 
it
      is added when walking the neighbor lists of a widget. Since a widget can 
be
      neighbors with multiple other widgets it could get added twice and hence
      the check is necessary. But the main body of 
is_connected_{input,output}_ep
      is guaranteed to be only executed at most once per widget. So adding the
      widget to the list at the beginning of the function automatically makes
      sure that each widget gets only added once. The only difference is that
      using this method the starting point itself will also end up on the list,
      but it can easily be skipped when creating the array.

      Overall this reduces the code size and speeds things slightly up.

      This patch adds names for missing irq types to the trace events.
      In order to identify adapter irqs, the define is moved from
      interrupt.c to the other basic irq defines in uapi/linux/kvm.h.

      KVM: s390: Fixup interrupt vcpu event messages and levels

      This reworks the debug logging for interrupt related logs.
      Several changes:
      - unify program int/irq
      - improve decoding (e.g. use mcic instead of parm64 for machine
        check injection)
      - remove useless interrupt type number (the name is enough)
      - rename "interrupt:" to "deliver:" as the other side is called "inject"
      - use log level 3 for state changing and/or seldom events (like machine
        checks, restart..)
      - use log level 4 for frequent events
      - use 0x prefix for hex numbers
      - add pfault done logging
      - move some tracing outside spinlock

      KVM: s390: remove "from (user|kernel)" from irq injection messages

      The "from user"/"from kernel" part of the log/trace messages is not
      always correct anymore and therefore not really helpful.

      Let's remove that part from the log + trace messages. For program
      interrupts, we can now move the logging/tracing part into the real
      injection function, as already done for the other injection functions.

      KVM: s390: filter space-switch events when PER is enforced

      When guest debugging is active, space-switch events might be enforced
      by PER. While the PER events are correctly filtered out,
      space-switch-events could be forwarded to the guest, although from a
      guest point of view, they should not have been reported.

      Therefore we have to filter out space-switch events being concurrently
      reported with a PER event, if the PER event got filtered out. To do so,
      we theoretically have to know which instruction was responsible for the
      event. As the applicable instructions modify the PSW address, the
      address space set in the PSW and even the address space in cr1, we
      can't figure out the instruction that way.

      For this reason, we have to rely on the information about the old and
      new address space, in order to guess the responsible instruction type
      and do appropriate checks for space-switch events.

      ath10k: enable raw encap mode and software crypto engine

      This patch enables raw Rx/Tx encap mode to support software based
      crypto engine. This patch introduces a new module param 'cryptmode'.

       cryptmode:

         0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
            encapsulation to the firmware. This is the default mode.
         1: Use sofware crypto engine globally with raw mode TX/RX
            encapsulation to the firmware.

      Known limitation:
         A-MSDU must be disabled for RAW Tx encap mode to perform well when
         heavy traffic is applied.

      ath10k: suppress 'failed to process fft' warning messages

      When using DFS channels on Ath10k, kernel log has repeated warning message
      'failed to process fft: -22' typically under medium/heavy traffic.

      This patch switches the warnings to driver debug (WMI events) mode only
      thus reducing log file noise.

      DFS and spectral scan share underlying HW mechanisms and enabling one
      (DFS) enables the other (spectral scan) as far as event reporting from
      firmware to driver is concerned. Spectral scan events take no part in
      processing of DFS radar pulses which are delivered as distinct events,
      so the fft (spectral event) warning is harmless and DFS interference
      detection/protection still occurs.

      Symptoms seen & fix tested in both debug & non-debug modes on TP-Link
      Archer C7 v2 platform.

      arch/*/io.h: Add ioremap_uc() to all architectures

      This adds ioremap_uc() only for architectures that do not
      include asm-generic.h/io.h as that already provides a default
      definition for them for both cases where you have CONFIG_MMU
      and you do not, and because of this, the number of architectures
      this patch address is less than the architectures that the
      ioremap_wt() patch addressed, "arch/*/io.h: Add ioremap_wt() to
      all architectures").

      In order to reduce the number of architectures we have to
      modify by adding new architecture IO APIs we'll have to review
      the architectures in this patch, see why they can't add
      asm-generic.h/io.h or issues that would be created by doing
      so and then spread a consistent inclusion of this header
      towards the end of their own header. For instance arch/metag
      includes the asm-generic/io.h *before* the ioremap*()
      definitions, this should be the other way around but only
      once we have guard wrappers for the non-MMU case also for
      asm-generic/io.h.

      Merge branch 'stmmac-cleanup'

      Joachim Eastwood says:

      ====================
      stmmac clean up for 4.3 part2

      This patch set creates proper probe functions in the remaining
      dwmac-* drivers, lets the drivers manage their own of match data
      structure, and cleans up some of the drivers a bit. Note that
      should be no functional change in any of the drivers.

      First patch from Fengguang fixes a Coccinelle that was found after
      the previous patch set when into next.

      Probe functions are best placed just above the platform_driver
      struct since it usually needs to call other functions in the
      driver but this requires some code movement in the drivers. To
      keep the conversion itself easier to review the code movement is
      done in separate patches. This creates some extra churn but I
      think it's worth it in this case.

      As only a couple of drivers actually needs to use of match data
      this pushed down from stmmac_platform and into the drivers. This
      also makes it possible for drivers to have their own match data
      structure. dwmac-rk benefits most from this.

      After each driver has it's own probe function and manages it's
      own match data the setup/free hooks and common match data struct
      are removed.

      Sorry for the slightly largish patch set this time around.

      Since I can only test the core changes on my platform and not the
      specific dwmac-drivers I greatly appreciate if people could test
      this on their respective platforms. I did spend quite a bit of
      time visually checking all these patches, but nothing beats real
      hardware testing. Thanks!

      zero respectively.

      powerpc/kernel: Add SIG_SYS support for compat tasks

      SIG_SYS was added in commit a0727e8ce513 "signal, x86: add SIGSYS info
      and make it synchronous."

      Because we use the asm-generic struct siginfo, we got support for
      SIG_SYS for free as part of that commit.

      However there was no compat handling added for powerpc. That means we've
      been advertising the existence of signfo._sifields._sigsys to compat
      tasks, but not actually filling in the fields correctly.

      Luckily it looks like no one has noticed, presumably because the only
      user of SIGSYS in the kernel is seccomp filter, which we don't support
      yet.

      So before we enable seccomp filter, add compat handling for SIGSYS.

      powerpc: Change syscall_get_nr() to return int

      The documentation for syscall_get_nr() in asm-generic says:

       Note this returns int even on 64-bit machines. Only 32 bits of
       system call number can be meaningful. If the actual arch value
       is 64 bits, this truncates to 32 bits so 0xffffffff means -1.

      However our implementation was never updated to reflect this.

      Generally it's not important, but there is once case where it matters.

      For seccomp filter with SECCOMP_RET_TRACE, the tracer will set
      regs->gpr[0] to -1 to reject the syscall. When the task is a compat
      task, this means we end up with 0xffffffff in r0 because ptrace will
      zero extend the 32-bit value.

      If syscall_get_nr() returns an unsigned long, then a 64-bit kernel will
      see a positive value in r0 and will incorrectly allow the syscall
      through seccomp.

      powerpc: Use orig_gpr3 in syscall_get_arguments()

      Currently syscall_get_arguments() is used by syscall tracepoints, and
      collect_syscall() which is used in some debugging as well as
      /proc/pid/syscall.

      The current implementation just copies regs->gpr[3 .. 5] out, which is
      fine for all the current use cases.

      When we enable seccomp filter, that will also start using
      syscall_get_arguments(). However for seccomp filter we want to use r3
      as the return value of the syscall, and orig_gpr3 as the first
      parameter. This will allow seccomp to modify the return value in r3.

      To support this we need to modify syscall_get_arguments() to return
      orig_gpr3 instead of r3. This is safe for all uses because orig_gpr3
      always contains the r3 value that was passed to the syscall. We store it
      in the syscall entry path and never modify it.

      Update syscall_set_arguments() while we're here, even though it's never
      used.

      Currently the only caller of syscall_set_return_value() is seccomp

      This means we have not noticed that our implementation of

      So remove the negation in syscall_set_return_value(), and expect the

      It also doesn't deal with compat, and doesn't deal with TIF_NOERROR.

      powerpc/kernel: Change the do_syscall_trace_enter() API

      The API for calling do_syscall_trace_enter() is currently sensible
      enough, it just returns the (modified) syscall number.

      However once we enable seccomp filter it will get more complicated. When
      seccomp filter runs, the seccomp kernel code (via SECCOMP_RET_ERRNO), or
      a ptracer (via SECCOMP_RET_TRACE), may reject the syscall and *may* or may
      *not* set a return value in r3.

      That means the assembler that calls do_syscall_trace_enter() can not
      blindly return ENOSYS, it needs to only return ENOSYS if a return value
      has not already been set.

      There is no way to implement that logic with the current API. So change
      the do_syscall_trace_enter() API to make it deal with the return code
      juggling, and the assembler can then just return whatever return code it
      is given.

      powerpc/kernel: Switch to using MAX_ERRNO

      Currently on powerpc we have our own #define for the highest (negative)
      errno value, called _LAST_ERRNO. This is defined to be 516, for reasons
      which are not clear.

      The generic code, and x86, use MAX_ERRNO, which is defined to be 4095.

      In particular seccomp uses MAX_ERRNO to restrict the value that a
      seccomp filter can return.

      Currently with the mismatch between _LAST_ERRNO and MAX_ERRNO, a seccomp
      tracer wanting to return 600, expecting it to be seen as an error, would
      instead find on powerpc that userspace sees a successful syscall with a
      return value of 600.

      To avoid this inconsistency, switch powerpc to use MAX_ERRNO.

      We are somewhat confident that generic syscalls that can return a
      non-error value above negative MAX_ERRNO have already been updated to
      use force_successful_syscall_return().

      I have also checked all the powerpc specific syscalls, and believe that
      none of them expect to return a non-error value between -MAX_ERRNO and
      -516. So this change should be safe ...

      xfs: create new metadata UUID field and incompat flag

      This adds a new superblock field, sb_meta_uuid.  If set, along with
      a new incompat flag, the code will use that field on a V5 filesystem
      to compare to metadata UUIDs, which allows us to change the user-
      visible UUID at will.  Userspace handles the setting and clearing
      of the incompat flag as appropriate, as the UUID gets changed; i.e.
      setting the user-visible UUID back to the original UUID (as stored in
      the new field) will remove the incompatible feature flag.

      If the incompat flag is not set, this copies the user-visible UUID into
      into the meta_uuid slot in memory when the superblock is read from disk;
      the meta_uuid field is not written back to disk in this case.

      The remainder of this patch simply switches verifiers, initializers,
      etc to use the new sb_meta_uuid field.

      xfs: Use consistent logging message prefixes

      The second and subsequent lines of multi-line logging messages
      are not prefixed with the same information as the first line.

      Separate messages with newlines into multiple calls to ensure
      consistent prefixing and allow easier grep use.

      xfs: validate transaction header length on log recovery

      When log recovery hits a new transaction, it copies the transaction
      header from the expected location in the log to the in-core structure
      using the length from the op record header. This length is validated to
      ensure it doesn't exceed the length of the record, but not against the
      expected size of a transaction header (and thus the size of the in-core
      structure). If the on-disk length is corrupted, the associated memcpy()
      can overflow, write to unrelated memory and lead to crashes. This has
      been reproduced via filesystem fuzzing.

      The code currently handles the possibility that the transaction header
      is split across two op records. Neither instance accounts for corruption
      where the op record length might be larger than the in-core transaction
      header. Update both sites to detect such corruption, warn and return an
      error from log recovery. Also add some comments and assert that if the
      record is split, the copy of the second portion is less than a full
      header. Otherwise, this suggests the copy of the second portion could
      have overwritten bits from the first and thus that something could be
      wrong.

      xfs: close xc_cil list_empty() races with cil commit sequence

      We have seen somewhat rare reports of the following assert from
      xlog_cil_push_background() failing during ltp tests or somewhat
      innocuous desktop root fs workloads (e.g., virt operations, initramfs
      construction):

          ASSERT(!list_empty(&cil->xc_cil));

      The reasoning behind the assert is that the transaction has inserted
      items to the CIL and hit background push codepath all with
      cil->xc_ctx_lock held for reading. This locks out background commit from
      emptying the CIL, which acquires the lock for writing. Therefore, the
      reasoning is that the items previously inserted in the CIL should still
      be present.

      The cil->xc_ctx_lock read lock is not sufficient to protect the xc_cil
      list, however, due to how CIL insertion is handled.
      xlog_cil_insert_items() inserts and reorders the dirty transaction items
      to the tail of the CIL under xc_cil_lock. It uses list_move_tail() to
      achieve insertion and reordering in the same block of code. This
      function removes and reinserts an item to the tail of the list. If a
      transaction commits an item that was already logged and thus already
      resides in the CIL, and said item is the sole item on the list, the
      removal and reinsertion creates a temporary state where the list is
      actually empty.

      This state is not valid and thus should never be observed by concurrent
      transaction commit-side checks in the circumstances outlined above. We
      do not want to acquire the xc_cil_lock in all of these instances as it
      was previously removed and replaced with a separate push lock for
      performance reasons. Therefore, close any races with list_empty() on the
      insertion side by ensuring that the list is never in a transient empty
      state.

      clk: exynos4: Fix wrong clock for Exynos4x12 ADC

      The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver.
      However TSADC is present only on Exynos4210 so on Trats2 board (with
      Exynos4412 SoC) the exynos-adc driver could not be probed:
         ERROR: could not get clock /adc@126C0000:adc(0)
         exynos-adc 126c0000.adc: failed getting clock, err = -2
         exynos-adc: probe of 126c0000.adc failed with error -2

      Instead on Exynos4x12 SoCs the main clock used by Analog to Digital
      Converter is located in different register and it is named in datasheet
      as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock
      is the same as purpose of TSADC from Exynos4210.

      The patch adds gate clock for Exynos4x12 using the proper register so
      backward compatibility is preserved. This fixes the probe of exynos-adc
      driver on Exynos4x12 boards and allows accessing sensors connected to it
      on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

      clk: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      clk: allow a clk divider with max divisor when zero

      This commit allows certain Broadcom STB clock dividers to be used with
      clk-divider.c.  It allows for a clock whose field value is the equal
      to the divisor, execpt when the field value is zero, in which case the
      divisor is 2^width.  For example, consider a divisor clock with a two
      bit field:

      value             divisor
      0         4
      1         1
      2         2
      3         3

      clk: pxa: fix core frequency reporting unit

      Legacy drivers which are not yet ported, such as cpufreq-pxa[23]xx, rely
      on pxaXXx_get_clk_frequency_khz() to find the CPU core frequency.

      This reporting was broken because the expected unit is kHz and not
      Hz. Fix the reporting for pxa25x, pxa27x and pxa3xx.

      clk: rockchip: Fix PLL bandwidth

      In the TRM we see that BWADJ is "a 12-bit bus that selects the values
      1-4096 for the bandwidth divider (NB)":
       NB = BWADJ[11:0] + 1
      The recommended setting of NB: NB = NF / 2.

      So:
        NB = NF / 2
        BWADJ[11:0] + 1 = NF / 2
        BWADJ[11:0] = NF / 2 - 1

      Right now, we have:

      {                                               \
              .rate   = _rate##U,                     \
              .nr = _nr,                              \
              .nf = _nf,                              \
              .no = _no,                              \
              .bwadj = (_nf >> 1),                    \
      }

      That means we set bwadj to NF / 2, not NF / 2 - 1

      All of this is a bit confusing because we specify "NR" (the 1-based
      value), "NF" (the 1-based value), "NO" (the 1-based value), but
      "BWADJ" (the 0-based value) instead of "NB" (the 1-based value).

      Let's change to working with "NB" and fix the off by one error.  This
      may affect PLL jitter in a small way (hopefully for the better).

      clk: Allow providers to configure min/max rates

      clk providers are using the consumer APIs to set min/max rates on
      the clock they're providing. To encourage clk providers to move
      away from the consumer APIs, add a provider API to set the
      min/max rate of a clock. The assumption is that this is done
      before the clock can be requested via clk_get() and that the
      clock rate is already within the boundaries of the min/max that's
      configured.

      jbd2: avoid infinite loop when destroying aborted journal

      Commit 6f6a6fda2945 "jbd2: fix ocfs2 corrupt when updating journal

      when the journal is aborted. That makes logic in
      jbd2_log_do_checkpoint() bail out which is fine, except that
      jbd2_journal_destroy() expects jbd2_log_do_checkpoint() to always make
      a progress in cleaning the journal. Without it jbd2_journal_destroy()
      just loops in an infinite loop.

      Fix jbd2_journal_destroy() to cleanup journal checkpoint lists of
      jbd2_log_do_checkpoint() fails with error.

      clk: h8300: Drop allocation printk and cleanup sizeof style

      We don't need to print an error on allocation failures, drop it.
      While we're here, change the sizeof() to be sizeof(*<ptr>) to
      make code more future proof.

      cpufreq: powernv: Restore cpu frequency to policy->cur on unthrottling

      cpufreq: powernv: Report Psafe only if PMSR.psafe_mode_active bit is set

      On a reset cycle of OCC, although the system retires from safe
      frequency state the local pstate is not restored to Pmin or last
      requested pstate. Now if the cpufreq governor initiates a pstate
      change, the local pstate will be in Psafe and we will be reporting a
      false positive when we are not throttled.

      So in powernv_cpufreq_throttle_check() remove the condition which
      checks if local pstate is less than Pmin while checking for Psafe
      frequency. If the cpus are forced to Psafe then PMSR.psafe_mode_active
      bit will be set. So, when OCCs become active this bit will be cleared.
      Let us just rely on this bit for reporting throttling.

      cpufreq: powernv: Call throttle_check() on receiving OCC_THROTTLE

      Re-evaluate the chip's throttled state on recieving OCC_THROTTLE
      notification by executing *throttle_check() on any one of the cpu on
      the chip. This is a sanity check to verify if we were indeed
      throttled/unthrottled after receiving OCC_THROTTLE notification.

      We cannot call *throttle_check() directly from the notification
      handler because we could be handling chip1's notification in chip2. So
      initiate an smp_call to execute *throttle_check(). We are irq-disabled
      in the notification handler, so use a worker thread to smp_call
      throttle_check() on any of the cpu in the chipmask.

      cpufreq: powernv: Register for OCC related opal_message notification

      OCC is an On-Chip-Controller which takes care of power and thermal
      safety of the chip. During runtime due to power failure or
      overtemperature the OCC may throttle the frequencies of the CPUs to
      remain within the power budget.

      We want the cpufreq driver to be aware of such situations to be able
      to report the reason to the user. We register to opal_message_notifier
      to receive OCC messages from opal.

      powernv_cpufreq_throttle_check() reports any frequency throttling and
      this patch will report the reason or event that caused throttling. We
      can be throttled if OCC is reset or OCC limits Pmax due to power or
      thermal reasons. We are also notified of unthrottling after an OCC
      reset or if OCC restores Pmax on the chip.

      powerpc/powernv: Add definition of OPAL_MSG_OCC message type

      Add OPAL_MSG_OCC message definition to opal_message_type to receive
      OCC events like reset, load and throttled. Host performance can be
      affected when OCC is reset or OCC throttles the max Pstate.
      We can register to opal_message_notifier to receive OPAL_MSG_OCC type
      of message and report it to the userspace so as to keep the user
      informed about the reason for a performance drop in workloads.

      The reset and load OCC events are notified to kernel when FSP sends
      OCC_RESET and OCC_LOAD commands.  Both reset and load messages are
      sent to kernel on successful completion of reset and load operation
      respectively.

      The throttle OCC event indicates that the Pmax of the chip is reduced.
      The chip_id and throttle reason for reducing Pmax is also queued along
      with the message.

      cpufreq: powernv: Handle throttling due to Pmax capping at chip level

      The On-Chip-Controller(OCC) can throttle cpu frequency by reducing the
      max allowed frequency for that chip if the chip exceeds its power or
      temperature limits. As Pmax capping is a chip level condition report
      this throttling behavior at chip level and also do not set the global
      'throttled' on Pmax capping instead set the per-chip throttled
      variable. Report unthrottling if Pmax is restored after throttling.

      This patch adds a structure to store chip id and throttled state of
      the chip.

      cpufreq: Drop cpufreq_policy_restore()

      Notice that when cpufreq_policy_restore() is called, its per-CPU
      cpufreq_cpu_data variable has been already dereferenced and if that
      variable is not NULL, the policy local pointer in cpufreq_add_dev()
      contains its value.

      Therefore it is not necessary to dereference it again and the
      policy pointer can be used directly.  Moreover, if that pointer
      is not NULL, the policy is inactive (or the previous check would
      have made us return from cpufreq_add_dev()) so the restoration
      code from cpufreq_policy_restore() can be moved to that point
      in cpufreq_add_dev().

      Do that and drop cpufreq_policy_restore().

      drm/i915: Keep the mm.bound_list in rough LRU order

      When we shrink our working sets, we want to avoid stealing pages from
      objects that likely to be reused in the near future. We first look at
      inactive objects before processing active objects - but what about a
      recently active object that is about to be used again. That object's
      position in the bound_list is ordered by the time of binding, not the
      time of last use, so the most recently used inactive object could well
      be at the head of the shrink list. To compensate, give the object a bump
      to MRU when it becomes inactive (thus transitioning to the end of the
      first pass in shrink lists). Conversely, bumping on inactive makes
      bumping on active useless, since when we do have to reap from the active
      working set, everything is going to become inactive very quickly and the
      order pretty much random - just hope for the best at that point, as once
      we start stalling on active objects, we can hope that the rebinding

      arm64: spinlock: fix ll/sc unlock on big-endian systems

      When unlocking a spinlock, we perform a read-modify-write on the owner
      ticket in order to increment it and store it back with release
      semantics.

      In the LL/SC case, we load the 16-bit ticket using a 32-bit load and
      therefore store back the wrong halfword on a big-endian system,
      corrupting the lock after the first unlock and killing the system dead.

      This patch fixes the unlock code to use 16-bit accessors consistently.

      Smack: IPv6 host labeling

      IPv6 appears to be (finally) coming of age with the
      influx of autonomous devices. In support of this, add
      the ability to associate a Smack label with IPv6 addresses.

      This patch also cleans up some of the conditional

      ARM: sunxi: dt: Convert users to the PIO interrupts binding

      The current DTs were setting the cell size to 2, but used the default 
xlate
      function that was assuming an interrupt cell size of 1, leading to the
      second part of the cell (the flags) being ignored, while we were having an
      inconsistent binding between the interrupts and gpio (that could also be
      used as interrupts).

      That "binding" doesn't work either with newer SoCs that have multiple irq
      banks.

      Now that we fixed the pinctrl driver to handle this like it should always
      have been handled, convert the DT users, and while we're at it, remove the
      size-cells property of PIO that is completely useless.

      ARM: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed. There appears to be a great deal of
      blind copy and paste of this code.

      arm64: Use last level TLBI for user pte changes

      The flush_tlb_page() function is used on user address ranges when PTEs
      (or PMDs/PUDs for huge pages) were changed (attributes or clearing). For
      such cases, it is more efficient to invalidate only the last level of
      the TLB with the "tlbi vale1is" instruction.

      In the TLB shoot-down case, the TLB caching of the intermediate page
      table levels (pmd, pud, pgd) is handled by __flush_tlb_pgtable() via the
      __(pte|pmd|pud)_free_tlb() functions and it is not deferred to
      tlb_finish_mmu() (as of commit 285994a62c80 - "arm64: Invalidate the TLB
      corresponding to intermediate page table levels"). The tlb_flush()
      function only needs to invalidate the TLB for the last level of page
      tables; the __flush_tlb_range() function gains a fourth argument for
      last level TLBI.

      ARM: mvebu: Warn about the wake-up sources not taken into account in 
suspend

      On the Armada 370/XP/38x/39x SoCs when the suspend to ram feature is
      supported, the SoCs are shutdown and will be woken up by an external
      micro-controller, so there is no possibility to setup wake-up sources
      from Linux. However, in standby mode, the SoCs stay powered and it is
      possible to wake-up from any interrupt sources. Since when the users
      configures the enabled wake-up sources there is no way to know if the
      user will be doing suspend to RAM or standby, we just allow all
      wake-up sources to be enabled, and only warn when entering suspend to
      RAM

      The purpose of this patch is to inform the user that in suspend to ram
      mode, the wake-up sources won't be taken into consideration.

      Intel integrated DMA (iDMA) 64-bit is a specific IP that is used as a 
part of
      LPSS devices such as HSUART or SPI. The iDMA IP is attached for private
      usage on each host controller independently.

      While it has similarities with Synopsys DesignWare DMA, the following
      distinctions doesn't allow to use the existing driver:
      - 64-bit mode with corresponding changes in Hardware Linked List data 
structure
      - many slight differences in the channel registers

      Moreover this driver is based on the DMA virtual channels framework that 
helps
      to make the driver cleaner and easy to understand.

      ACPI / PM: Attach ACPI power domain only once

      Some devices, like MFD subdevices, share a single ACPI companion device so
      that they are able to access their resources and children. However,
      currently all these subdevices are attached to the ACPI power domain and
      this might cause that the power methods for the companion device get 
called
      more than once.

      In order to solve this we attach the ACPI power domain only to the first

      PM / QoS: Make it possible to expose device latency tolerance to userspace

      Typically when a device is created the bus core it belongs to (for example
      PCI) does not know if the device supports things like latency tolerance.
      This is left to the driver that binds to the device in question. However,
      at that time the device has already been created and there is no way to 
set
      its dev->power.set_latency_tolerance anymore.

      So follow what has been done for other PM QoS attributes as well and allow
      drivers to expose and hide latency tolerance from userspace, if the device
      supports it.

      gpio: kill off set_irq_flags usage

      set_irq_flags is ARM specific with custom flags which have genirq
      equivalents. Convert drivers to use the genirq interfaces directly, so we
      can kill off set_irq_flags. The translation of flags is as follows:

      IRQF_VALID -> !IRQ_NOREQUEST
      IRQF_PROBE -> !IRQ_NOPROBE
      IRQF_NOAUTOEN -> IRQ_NOAUTOEN

      For IRQs managed by an irqdomain, the irqdomain core code handles clearing
      and setting IRQ_NOREQUEST already, so there is no need to do this in
      .map() functions and we can simply remove the set_irq_flags calls. Some
      users also modify IRQ_NOPROBE and this has been maintained although it
      is not clear that is really needed as most platforms don't use probing.
      There appears to be a great deal of blind copy and paste of this code.

      Add support for the three ARS DSM commands:
      - Query ARS Capabilities - Queries the firmware to check if a given
        range supports scrub, and if so, which type (persistent vs. volatile)
      - Start ARS - Starts a scrub for a given range/type
      - Query ARS Status - Checks status of a previously started scrub, and
        provides the error logs if any.

        The commands are described by the example DSM spec at:
        http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf

      clk: change clk_ops' ->determine_rate() prototype

      Clock rates are stored in an unsigned long field, but ->determine_rate()
      (which returns a rounded rate from a requested one) returns a long
      value (errors are reported using negative error codes), which can lead
      to long overflow if the clock rate exceed 2Ghz.

      Change ->determine_rate() prototype to return 0 or an error code, and pass
      a pointer to a clk_rate_request structure containing the expected target
      rate and the rate constraints imposed by clk users.

      The clk_rate_request structure might be extended in the future to contain
      other kind of constraints like the rounding policy, the maximum clock
      inaccuracy or other things that are not yet supported by the CCF
      (power consumption constraints ?).

      to the Marzen-reference case, so simply remove the Marzen C board
      code to fall over on the generic r8a7779 machine vector.

      PCI: Remove unused "pci_probe" flags

      The following flags are only used on x86, but they got copied to FR-V,
      MN10300, and SuperH:

        PCI_PROBE_BIOS
        PCI_PROBE_CONF1
        PCI_PROBE_CONF2
        PCI_ASSIGN_ROMS
        PCI_NO_CHECKS
        PCI_BIOS_IRQ_SCAN
        PCI_ASSIGN_ALL_BUSSES

      FR-V and MN10300 do test for PCI_ASSIGN_ROMS, but they never set it, so
      it's dead code.

      Remove the unused flags above.

      ====================
      net/mlx4_en: Hardware accelerated 802.1ad

      This patchset by Hadar introduces support in Hardware accelerated 
802.1ad, for
      ConnectX-3pro NIC's.  In order to support existing deployment, and due to 
some
      hardware limitations, the feature is disabled by default, and needed to be
      enabled using a private flag in ethtool. Ofcourse user can enable the 
private
      flag only if hardware has support.
      After being enabled, the standard ethtool -k/-K can be used.

      Patchset was applied and tested over commit 71790a2 ("hv_netvsc: Add 
structs
      and handlers for VF messages")

      net/mlx4_en: Add support for hardware accelerated 802.1ad vlan

      To enable device support in accelerated 802.1ad vlan, the port
      capability "packet has vlan enable" (phv_en) should be set.
      Firmware won't work properly, in case phv_en is not set.

      The user can enable "phv_en" port capability with the new ethtool
      private flag phv-bit. The phv-bit private flag default value is OFF,
      users who are interested in 802.1ad hardware acceleration should turn ON
      the phv-bit private flag:
      $ ethtool --set-priv-flags eth1 phv-bit on

      Once the private flag is set, the device is ready for 802.1ad vlan
      acceleration.

      The user should also change the interface device features and turn on
      "tx-vlan-stag-hw-insert" which is off by default:
      $ ethtool -K eth1  tx-vlan-stag-hw-insert on

      "phv-bit" private flag setting is available only for Physical
      Functions(PF), the Virtual Function (VF) will be able to use the feature
      by setting "tx-vlan-stag-hw-insert" ethtool device feature only if the
      feature was enabled by the Hypervisor.

      To allow 802.1ad accelerated device, "packet has vlan" (phv)

          (Arnaldo Carvalho de Melo)

      User visible fixes:

        - Expose perf's symbol resolver to libtraceevent, so that its plugins 
can
          resolve tracepoint fields to kernel functions, like the 'function' 
field
          in the "timer:hrtimer_start tracepoint" (Arnaldo Carvalho de Melo)

        - Map propagation of thread and cpu maps improvements, prep work for
          'perf stat' new features (Jiri Olsa)

      pinctrl: nomadik: depromote GPIO to subsystem_init()

      We no longer have to do GPIO initialization before the
      pinctrl initialization, instead we can initialize the pinctrl
      portions of the driver first and then the GPIO. Thus we can
      move GPIO initialization to a subsystem_initcall(), but
      not yet to a device_initcall().

      pinctrl/ARM: move GPIO and pinctrl deps to device tree

      This gets the GPIO ranges out of the driver and into the device
      tree where they belong. Standard DT bindings already exist for
      this. Since no systems with this are deployed we can just augment
      all device trees and the drivers at the same time and simplify
      the world.

      This also defines the array of GPIO chips related to the pin
      controller.

      pinctrl: sunxi: Add custom irq_domain_ops

      The current interrupt parsing code was working by accident, because the
      default was actually parsing the first node of interrupts.

      While that was mostly working (and the flags were actually ignored), this
      binding has never been documented, and doesn't work with SoCs that have
      multiple interrupt banks anyway.

      Add a proper interrupt xlate function, that uses the same description than
      the GPIOs (<bank> <pin> <flags>), that will make things less confusing.

      The EINT number will still be used as the hwirq number, but won't be
      exposed through the DT.

      gpio: omap: use raw locks for locking

      This patch converts gpio_bank.lock from a spin_lock into a
      raw_spin_lock. The call path is to access this lock is always under a
      raw_spin_lock, for instance
      - __setup_irq() holds &desc->lock with irq off
        + __irq_set_trigger()
         + omap_gpio_irq_type()

      - handle_level_irq() (runs with irqs off therefore raw locks)
        + mask_ack_irq()
         + omap_gpio_mask_irq()

      This fixes the obvious backtrace on -RT. However the locking vs context
      is not and this is not limited to -RT:
      - omap_gpio_irq_type() is called with IRQ off and has an conditional
        call to pm_runtime_get_sync() which may sleep. Either it may happen or
        it may not happen but pm_runtime_get_sync() should not be called with
        irqs off.

      - omap_gpio_debounce() is holding the lock with IRQs off.
        + omap2_set_gpio_debounce()
         + clk_prepare_enable()
          + clk_prepare() this one might sleep.
        The number of users of gpiod_set_debounce() / gpio_set_debounce()
        looks low but still this is not good.

      tile: Provide atomic_{or,xor,and}

      Implement atomic logic ops -- atomic_{or,xor,and}.

      For tilegx, these are relatively straightforward; the architecture
      provides atomic "or" and "and", both 32-bit and 64-bit.  To support
      xor we provide a loop using "cmpexch".

      For the older 32-bit tilepro architecture, we have to extend
      the set of low-level assembly routines to include 32-bit "and",
      as well as all three 64-bit routines.  Somewhat confusingly,
      some 32-bit versions are already used by the bitops inlines, with
      parameter types appropriate for bitops, so we have to do a bit of
      casting to match "int" to "unsigned long".

      frv: Rewrite atomic implementation

      Mostly complete rewrite of the FRV atomic implementation, instead of
      using assembly files, use inline assembler.

      The out-of-line CONFIG option makes a bit of a mess of things, but a
      little CPP trickery gets that done too.

      FRV already had the atomic logic ops but under a non standard name,
      the reimplementation provides the generic names and provides the
      intermediate form required for the bitops implementation.

      The slightly inconsistent __atomic32_fetch_##op naming is because
      __atomic_fetch_##op conlicts with GCC builtin functions.

      The 64bit atomic ops use the inline assembly %Ln construct to access
      the low word register (r+1), afaik this construct was not previously
      used in the kernel and is completely undocumented, but I found it in
      the FRV GCC code and it seems to work.

      FRV had a non-standard definition of atomic_{clear,set}_mask() which
      would work types other than atomic_t, the one user relying on that
      (arch/frv/kernel/dma.c) got converted to use the new intermediate
      form.

      arm64/BUG: Show explicit backtrace for WARNs

      The generic slowpath WARN implementation prints a backtrace, but
      the report_bug() based implementation does not, opting to print the
      registers instead which is generally not as useful.

      Ideally, report_bug() should be fixed to make the behaviour more
      consistent, but in the meantime this patch generates a backtrace
      directly from the arm64 backend instead so that this functionality
      is not lost with the migration to report_bug().

      As a side-effect, the backtrace will be outside the oops end
      marker, but that's hard to avoid without modifying generic code.

      This patch can go away if report_bug() grows the ability in the
      future to generate a backtrace directly or call an arch hook at the
      appropriate time.

      arm64/BUG: Use BRK instruction for generic BUG traps

      Currently, the minimal default BUG() implementation from asm-
      generic is used for arm64.

      This patch uses the BRK software breakpoint instruction to generate
      a trap instead, similarly to most other arches, with the generic
      BUG code generating the dmesg boilerplate.

      This allows bug metadata to be moved to a separate table and
      reduces the amount of inline code at BUG and WARN sites.  This also
      avoids clobbering any registers before they can be dumped.

      To mitigate the size of the bug table further, this patch makes
      use of the existing infrastructure for encoding addresses within
      the bug table as 32-bit offsets instead of absolute pointers.
      (Note that this limits the kernel size to 2GB.)

      Traps are registered at arch_initcall time for aarch64, but BUG
      has minimal real dependencies and it is desirable to be able to
      generate bug splats as early as possible.  This patch redirects
      all debug exceptions caused by BRK directly to bug_handler() until
      the full debug exception support has been initialised.

      arm64/debug: Simplify BRK insn opcode declarations

      The way the KGDB_DYN_BRK_INS_BYTEx macros are declared is more
      complex than it needs to be.  Also, the macros are only used in one
      place, which is arch-specific anyway.

      This patch refactors the macros to simplify them, and exposes an
      argument so that we can have a single macro instead of 4.

      As a side effect, this patch also fixes some anomalous spellings of
      "KGDB".

      These changes alter the compile types of some integer constants
      that are harmless but trigger truncation warnings in gcc when
      assigning to 32-bit variables.  This patch adds an explicit cast
      for the affected cases.

      arm64: kernel: Add support for Privileged Access Never

      'Privileged Access Never' is a new arm8.1 feature which prevents
      privileged code from accessing any virtual address where read or write
      access is also permitted at EL0.

      This patch enables the PAN feature on all CPUs, and modifies 
{get,put}_user
      helpers temporarily to permit access.

      This will catch kernel bugs where user memory is accessed directly.
      'Unprivileged loads and stores' using ldtrb et al are unaffected by PAN.

      arm64: Generalise msr_s/mrs_s operations

      The system register encoding generated by sys_reg() works only
      for MRS/MSR(Register) operations, as we hardcode Bit20 to 1 in
      mrs_s/msr_s mask. This makes it unusable for generating instructions
      accessing registers with Op0 < 2(e.g, PSTATE.x with Op0=0).

      As per ARMv8 ARM, (Ref: ARMv8 ARM, Section: "System instruction class
      encoding overview", C5.2, version:ARM DDI 0487A.f), the instruction
      encoding reserves bits [20-19] for Op0.

      This patch generalises the sys_reg, mrs_s and msr_s macros, so that
      we could use them to access any of the supported system register.

      arm64: kernel: Add optional CONFIG_ parameter to ALTERNATIVE()

      Some uses of ALTERNATIVE() may depend on a feature that is disabled at
      compile time by a Kconfig option. In this case the unused alternative
      instructions waste space, and if the original instruction is a nop, it
      wastes time and space.

      This patch adds an optional 'config' option to ALTERNATIVE() and
      alternative_insn that allows the compiler to remove both the original
      and alternative instructions if the config option is not defined.

      The existing alternative_insn macro has some limitations that make it

      own macro arguments means it doesn't play very nicely with C pre-processor
      macros because the macro arguments look like a string to the C

      arm64: perf: condense event number maps

      Most of the cache events an architecture might support do not map well
      to those provided by the ARM architecture, and as such most entries in
      the event number maps are *_UNSUPPORTED. Unfortuantely as 0 is a valid
      physical event identifier, the *_UNSUPPORTED macros expand to a non-zero
      value and thus each unsupported event must be explicitly initialised as
      such. This leads to large diffs when adding support for a new CPU, and
      makes it difficult to spot the important information.

      This patch follows arch/arm/ in making use of PERF_*_ALL_UNSUPPORTED
      macros to initialise all entries to *_UNSUPPORTED before overriding this
      for the specific events we actually support, resulting in a significant
      source code reduction.

      arm64: dma-mapping: implement dma_get_sgtable()

      The default dma_common_get_sgtable() implementation relies on the CPU
      address of the buffer being a regular lowmem address. This is not always
      the case on arm64, since allocations from the various DMA pools may have
      remapped vmalloc addresses, rendering the use of virt_to_page() invalid.

      Fix this by providing our own implementation based on the fact that we
      can safely derive a physical address from the DMA address in both cases.

      arm64: Better native ptrace support for compat tasks

      The compat ptrace interface allows access to the TLS register, hardware
      breakpoints and watchpoints, syscall number. However, a native task
      using the native ptrace interface to debug compat tasks (e.g. multi-arch
      gdb) only has access to the general and VFP register sets. The compat
      ptrace interface cannot be accessed from a native task.

      This patch adds a new user_aarch32_ptrace_view which contains the TLS,
      hardware breakpoint/watchpoint and syscall number regsets in addition to
      the existing GPR and VFP regsets. This view is backwards compatible with
      the previous kernels. Core dumping of 32-bit tasks and compat ptrace are
      not affected since the original user_aarch32_view is preserved.

      arm64: Add support for hardware updates of the access and dirty pte bits

      The ARMv8.1 architecture extensions introduce support for hardware
      updates of the access and dirty information in page table entries. With
      TCR_EL1.HA enabled, when the CPU accesses an address with the PTE_AF bit
      cleared in the page table, instead of raising an access flag fault the
      CPU sets the actual page table entry bit. To ensure that kernel
      modifications to the page tables do not inadvertently revert a change
      introduced by hardware updates, the exclusive monitor (ldxr/stxr) is
      adopted in the pte accessors.

      When TCR_EL1.HD is enabled, a write access to a memory location with the
      DBM (Dirty Bit Management) bit set in the corresponding pte
      automatically clears the read-only bit (AP[2]). Such DBM bit maps onto
      the Linux PTE_WRITE bit and to check whether a writable (DBM set) page
      is dirty, the kernel tests the PTE_RDONLY bit. In order to allow
      read-only and dirty pages, the kernel needs to preserve the software
      dirty bit. The hardware dirty status is transferred to the software
      dirty bit in ptep_set_wrprotect() (using load/store exclusive loop) and
      pte_modify().

      arm64: perf: replace arch_find_n_match_cpu_physical_id with 
of_cpu_device_node_get

      arch_find_n_match_cpu_physical_id parses the device tree to get the
      device node for a given logical cpu index. However, since ARM PMUs get
      probed after the CPU device nodes are stashed while registering the
      cpus, we can use of_cpu_device_node_get to avoid another DT parse.

      This patch replaces arch_find_n_match_cpu_physical_id with
      of_cpu_device_node_get to reuse the stashed value directly instead.

      pinctrl: driver for Conexant Digicolor CX92755 pin mapping

      This adds pinctrl and gpio driver to the CX92755 SoC "General
      Purpose Pin Mapping" hardware block. The CX92755 is one SoC
      from the Conexant Digicolor series. Pin mapping hardware supports
      configuring pins as either GPIO, or up to 3 other "client select"
      functions. This driver adds support for pin muxing using the
      generic device tree binding, and a basic gpiolib driver for
      the GPIO functionality.

      This driver does not currently support GPIO interrupts, and
      pad configuration.

      v2:
      * Address review comments for Linus Walleij:
        - Add a pointer to pinctrl_desc in struct dc_pinmap
        - Drop the now redundant pinctrl_pin_desc field
        - Adapt dc_get_group_{name,pins} to these changes, and
          add a comment explaining the 1-to-1 pin-groups relation

      drm/i915: kerneldoc for tiling IOCTL and swizzle functions

      Chris rightfully suggested that documenting fences without documenting
      the BO tiling tracking doesn't make much sense, so fix that.

      The important bit to stress here (since it lead to some confusion) is
      the GEM doesn't really care about tiling. Except for a few select cases
      where the kernel needs to manage something that userspace can't take
      care of: Namely the limited number of fences and fixing up swizzling,
      although we still fail at the later.

      v2: Move the low-level tiling/swizzling functions and kerneldoc to
      i915_gem_fence.c and leave only the userspace interface here.
      Suggested by Chris.

      tcp: tso: allow deferring under reordering state

      While doing experiments with reordering resilience, we found
      linux senders were not able to send at full speed under reordering,
      because every incoming SACK was releasing one MSS.

      This patch removes the limitation, as we did for CWR state
      in commit a0ea700e409 ("tcp: tso: allow CA_CWR state in
      tcp_tso_should_defer()")

      Neal Cardwell had a concern about limited transmit so
      Yuchung conducted experiments on GFE and found nothing
      worth adding an extra check on fast path :

        if (icsk->icsk_ca_state == TCP_CA_Disorder &&
            tcp_sk(sk)->reordering == sysctl_tcp_reordering)

      ravb: minimize TX data copying

      Renesas Ethernet AVB controller requires that all data are aligned on 
4-byte
      boundary.  While it's  easily achievable for  the RX  data with  the help 
of
      skb_reserve() (we even align on 128-byte boundary as recommended by the 
manual),
      we  can't  do the same with the TX data, and it always comes  unaligned 
from
      the networking core. Originally we solved it an easy way, copying all 
packet
      to  a  preallocated  aligned buffer; however, it's enough to copy only up 
to
      3 first bytes from each packet, doing the transfer using 2 TX descriptors
      instead of just 1. Here's an implementation of the new  TX algorithm that
      significantly reduces the driver's memory requirements.

      lwtunnel: change prototype of lwtunnel_state_get()

      It saves some lines and simplify a bit the code when the state is 
returning
      by this function. It's also useful to handle a NULL entry.

      To avoid too long lines, I've also renamed lwtunnel_state_get() and
      lwtunnel_state_put() to lwtstate_get() and lwtstate_put().

      net/mlx5e: TX latency optimization to save DMA reads

      A regular TX WQE execution involves two or more DMA reads -
      one to fetch the WQE, and another one per WQE gather entry.

      These DMA reads obviously increase the TX latency.
      There are two mlx5 mechanisms to bypass these DMA reads:
      1) Inline WQE
      2) Blue Flame (BF)

      An inline WQE contains a whole packet, thus saves the DMA read/s
      of the regular WQE gather entry/s. Inline WQE support was already
      added in the previous commit.

      A BF WQE is written directly to the device I/O mapped memory, thus
      enables saving the DMA read that fetches the WQE.

      The BF WQE I/O write must be in cache line granularity, thus uses
      the CPU write combining mechanism.
      A BF WQE I/O write acts also as a TX doorbell for notifying the
      device of new TX WQEs.
      A BF WQE is written to the same I/O mapped address as the regular TX
      doorbell, thus this address is being mapped twice - once by ioremap()
      and once by io_mapping_map_wc().

      While both mechanisms reduce the TX latency, they both consume more CPU
      cycles than a regular WQE:
      - A BF WQE must still be written to host memory, in addition to being
        written directly to the device I/O mapped memory.
      - An inline WQE involves copying the SKB data into it.

      To handle this tradeoff, we introduce here a heuristic algorithm that
      strives to avoid using these two mechanisms in case the TX queue is
      being back-pressured by the device, and limit their usage rate otherwise.

      An inline WQE will always be "Blue Flamed" (written directly to the
      device I/O mapped memory) while a BF WQE may not be inlined (may contain
      gather entries).

      Preliminary testing using netperf UDP_RR shows that the latency goes down
      from 17.5us to 16.9us, while the message rate (tested with pktgen) stays
      the same.

      irqchip/bcm7120-l2: Fix interrupt status for multiple parent IRQs

      Our irq-bcm7120-l2 interrupt controller driver utilizes the same handler
      function for the different parent interrupts it services: UPG_MAIN, 
UPG_BSC for
      instance.

      The problem is that function reads the IRQSTAT register which can combine
      interrupt causes for different parent interrupts, such that we can end-up 
in
      the following situation:

      - CPU takes an interrupt
      - bcm7120_l2_intc_irq_handle() reads IRQSTAT
      - generic_handle_irq() is invoked
      - there are still pending interrupts flagged in IRQSTAT from a different 
parent
      - handle_bad_irq() is invoked for these since they come from a different 
irq_desc/irq

      In order to fix this, make sure that we always mask IRQSTAT with the
      appropriate bits that correspond go the parent interrupt source this is 
coming
      from. To simplify things, associate an unique structure per parent 
interrupt
      handler to avoid multiplying the number of lookups.

      irqchip/bcm7120-l2: Perform suspend/resume even without installed child 
IRQs

      Make use of the new irq_chip_generic suspend/resume callbacks.

      This is required because if there are no installed child IRQs for this
      chip, the irq_chip::irq_{suspend,resume} functions will not be called.
      However, we still need to save/restore the forwarding mask, to enable
      the top-level GIC interrupt; otherwise, we lose UART output after S3
      resume.

      In addition to refactoring the callbacks, we have to self-initialize the
      mask cache, since the genirq core also doesn't initialize this until the
      first child IRQ is installed.

      The original problem report is described in extra detail here:

      genirq: Add chip_[suspend|resume] PM support to irq_chip

      Some (admittedly odd) irqchips perform functions that are not directly
      related to any of their child IRQ lines, and therefore need to perform
      some tasks during suspend/resume regardless of whether there are
      any "installed" interrupts for the irqchip. However, the current
      generic-chip framework does not call the chip's irq_{suspend,resume}
      when there are no interrupts installed (this makes sense, because there
      are no irq_data objects for such a call to be made).

      More specifically, irq-bcm7120-l2 configures both a forwarding mask
      (which affects other top-level GIC IRQs) and a second-level interrupt
      mask (for managing its own child interrupts). The former must be
      saved/restored on suspend/resume, even when there's nothing to do for
      the latter.

      This patch adds a new set of suspend/resume hooks to irq_chip_generic,
      to help represent *chip* suspend/resume, rather than IRQ suspend/resume.
      These callbacks will always be called for an IRQ chip (regardless of the
      installed interrupts) and are based on the per-chip irq_chip_generic
      struct, rather than the per-IRQ irq_data struct.

      The original problem report is described in extra detail here:

      irqchip: Appropriate __init annotation for const data

      Init data marked const should be annotated with __initconst for
      correctness and not __initdata.  And for those already __initconst,
      they should be qualified as const at the compiler level too.
      This also fixes LTO builds that otherwise fail with section mismatch

      irqchip/gic: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND

      The GIC controller doesn't provides any facility to configure the wakeup
      sources. For the same reason, GIC chip implementation can't provide
      irq_set_wake functionality, but that results in the irqchip core
      preventing the systems from entering sleep states like "suspend to RAM".

      The GICv1/v2 controllers support wakeup events. They signal these wakeup
      events even when CPU interface is disabled which means the wakeup
      outputs are always enabled with the required logic in always-on domain.
      An implementation can powerdown the GIC completely, but then the wake-up
      must be relayed to some control logic within the power controller that
      acts as wake-up interrupt controller.

      Setting the IRQCHIP_SKIP_SET_WAKE flags will ensure that the interrupts
      from GIC can work as wakeup interrupts and resume from suspend-to-{idle,
      ram}. The wakeup interrupt sources need to use enable_irq_wake() and the
      irqchip core will then set the IRQD_WAKEUP_STATE flag.

      Also it's always safer to mask all the non wakeup interrupts are masked
      at the chip level when suspending. The irqchip infrastructure can handle
      masking of those interrupts at the chip level. The chip implementation
      just have to indicate that with IRQCHIP_MASK_ON_SUSPEND.

      This patch enables IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so
      that the irqchip core allows and handles the power managemant wake up
      modes.

      net: bcmgenet: Register link_update callback for all MoCA PHYs

      Commit 8d88c6ebb34c ("net: bcmgenet: enable MoCA link state change
      detection") added a fixed PHY link_update callback for MoCA PHYs when
      registered using platform_data exclusively, this change is also
      applicable to systems using Device Tree as their primary configuration
      interface.

      In order for this to work, move the link_update assignment into
      bcmgenet_moca_phy_setup() where we know for sure that we are running on
      a MoCA GENET instance, and do not override phydev->link since this is:

      - properly taken care of by the PHY library by getting the link UP/DOWN
        interrupts
      - this now runs everytime we call bcmgenet_open(), so we need to
        preserve whatever we detected before we went administratively DOWN and
        then UP
      - we need to make sure that MoCA PHYs start with a link DOWN during
        probe in order to force a link transition to occur

      To avoid a forward declaration, move bcmgenet_fixed_phy_link_update()
      above its caller.

      Having every single function check for !IS_ERR(priv->clk) is both
      redundant and error prone, as it turns out, we were doing it for the
      main GENET clock: priv->clk, but not for the Wake-on-LAN or EEE clock,

      tipc: clean up socket layer message reception

      When a message is received in a socket, one of the call chains
      tipc_sk_rcv()->tipc_sk_enqueue()->filter_rcv()(->tipc_sk_proto_rcv())
      or
      tipc_sk_backlog_rcv()->filter_rcv()(->tipc_sk_proto_rcv())
      are followed. At each of these levels we may encounter situations
      where the message may need to be rejected, or a new message
      produced for transfer back to the sender. Despite recent
      improvements, the current code for doing this is perceived
      as awkward and hard to follow.

      Leveraging the two previous commits in this series, we now
      introduce a more uniform handling of such situations. We
      let each of the functions in the chain itself produce/reverse
      the message to be returned to the sender, but also perform the
      actual forwarding. This simplifies the necessary logics within

      tipc: introduce new tipc_sk_respond() function

      Currently, we use the code sequence

      if (msg_reverse())
         tipc_link_xmit_skb()

      at numerous locations in socket.c. The preparation of arguments
      for these calls, as well as the sequence itself, makes the code
      unecessarily complex.

      In this commit, we introduce a new function, tipc_sk_respond(),
      that performs this call combination. We also replace some, but not
      yet all, of these explicit call sequences with calls to the new
      function. Notably, we let the function tipc_sk_proto_rcv() use
      the new function to directly send out PROBE_REPLY messages,
      instead of deferring this to the calling tipc_sk_rcv() function,
      as we do now.

      tipc: let function tipc_msg_reverse() expand header when needed

      The shortest TIPC message header, for cluster local CONNECTED messages,
      is 24 bytes long. With this format, the fields "dest_node" and
      "orig_node" are optimized away, since they in reality are redundant
      in this particular case.

      However, the absence of these fields leads to code inconsistencies
      that are difficult to handle in some cases, especially when we need
      to reverse or reject messages at the socket layer.

      In this commit, we concentrate the handling of the absent fields
      to one place, by letting the function tipc_msg_reverse() reallocate
      the buffer and expand the header to 32 bytes when necessary. This
      means that the socket code now can assume that the two previously
      absent fields are present in the header when a message needs to be
      rejected. This opens up for some further simplifications of the
      socket code.

      intel_idle: allow idle states to be freeze-mode specific

      intel_idle uses a NULL "enter" field in a cpuidle state
      to recognize the invalid entry terminating a variable-length array.

      Linux-4.0 added support for the system-wide "freeze" state
      in cpuidle drivers via the new "enter_freeze" field.

      The natural way to expose a deep idle state for freeze,
      but not for run-time idle is to supply "enter_freeze" without "enter";
      so we update the driver to accept such states.

      ARM: mvebu: Add standby support

      Until now only one Armada XP and one Armada 388 based board supported
      suspend to ram. However, most of the recent mvebu SoCs can support the
      standby mode. Unlike for the suspend to ram, nothing special has to be
      done for these SoCs. This patch allows the system to use the standby
      mode on Armada 370, 38x, 39x and XP SoCs. There are issues with the
      Armada 375, and the support might be added (if possible) in a future
      patch.

      ARM: mvebu: prepare pm-board.c for the introduction of Armada 38x support

      The pm-board.c code contains the board-specific logic to enter suspend
      to RAM. Until now, the code supported only the Armada XP GP board, so
      all functions and symbols were named with armada_xp_gp. However, it
      turns out that the Armada 388 GP also uses the same 3 GPIOs protocol
      to talk to the PIC microcontroller that controls the power supply.

      Since we are going to re-use the same code with no change for Armada
      38x, this commit renames the functions and symbols to use just
      "armada" instead of "armada_xp_gp". Better names can be found if one
      day other boards having a different protocol/mechanism are supported
      in the kernel.

      ARM: move heavy barrier support out of line

      The existing memory barrier macro causes a significant amount of code
      to be inserted inline at every call site.  For example, in
      gpio_set_irq_type(), we have this for mb():

      c0344c08:       f57ff04e        dsb     st
      c0344c0c:       e59f8190        ldr     r8, [pc, #400]  ; c0344da4 
<gpio_set_irq_type+0x230>
      c0344c10:       e3590004        cmp     r9, #4
      c0344c14:       e5983014        ldr     r3, [r8, #20]
      c0344c18:       0a000054        beq     c0344d70 <gpio_set_irq_type+0x1fc>
      c0344c1c:       e3530000        cmp     r3, #0
      c0344c20:       0a000004        beq     c0344c38 <gpio_set_irq_type+0xc4>
      c0344c24:       e50b2030        str     r2, [fp, #-48]  ; 0xffffffd0
      c0344c28:       e50bc034        str     ip, [fp, #-52]  ; 0xffffffcc
      c0344c2c:       e12fff33        blx     r3
      c0344c30:       e51bc034        ldr     ip, [fp, #-52]  ; 0xffffffcc
      c0344c34:       e51b2030        ldr     r2, [fp, #-48]  ; 0xffffffd0
      c0344c38:       e5963004        ldr     r3, [r6, #4]

      Moving the outer_cache_sync() call out of line reduces the impact of
      the barrier:

      c0344968:       f57ff04e        dsb     st
      c034496c:       e35a0004        cmp     sl, #4
      c0344970:       e50b2030        str     r2, [fp, #-48]  ; 0xffffffd0
      c0344974:       0a000044        beq     c0344a8c <gpio_set_irq_type+0x1b8>
      c0344978:       ebf363dd        bl      c001d8f4 <arm_heavy_mb>
      c034497c:       e5953004        ldr     r3, [r5, #4]

      This should reduce the cache footprint of this code.  Overall, this
      results in a reduction of around 20K in the kernel size:

          text    data      bss      dec     hex filename
      10773970  667392 10369656 21811018 14ccf4a ../build/imx6/vmlinux-old
      10754219  667392 10369656 21791267 14c8223 ../build/imx6/vmlinux-new

      Another advantage to this approach is that we can finally resolve the
      issue of SoCs which have their own memory barrier requirements within
      multiplatform kernels (such as OMAP.)  Here, the bus interconnects
      need additional handling to ensure that writes become visible in the
      correct order (eg, between dma_map() operations, writes to DMA
      coherent memory, and MMIO accesses.)

      phy-sun4i-usb: Swap check for disconnect threshold

      Before this commit the code for determining the disconnect threshold was
      checking for "allwinner,sun4i-a10-usb-phy" or 
"allwinner,sun6i-a31-usb-phy"
      assuming that those where the exception and then newer SoCs would use a
      disconnect threshold of 2 like sun7i does. But it turns out that newer
      SoCs use a disconnect threshold of 3 and sun5i and sun7i are the
      exceptions, so check for those instead.

      Here are the settings from the various Allwinner SDK sources:
       sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
       sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
       sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun8i-h3:  USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
       sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);

      sun4i - sun7i.

      Intel Wired LAN Driver Updates 2015-07-23

      This series contains updates to e1000e, igb, ixgbevf, i40e and i40evf.

      Emil extends the reporting of the RSS key and hash table by adding support
      for x550 VFs.

      Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a
      call to pm_qos_remove_request() to cleanup the QoS request made in
      e1000_open().

      Todd updates igb to report unsupported for ethtool coalesce settings
      that are not supported.  Also updated the driver to use the ARRAY_SIZE()
      macro.

      Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf
      which would never change dynamically.  So update the switch() statement
      to have a default case and switch on "new_latency_range" versus the
      current ITR setting.

      Shannon cleans up i40e code, where there were un-needed goto's.  Also
      clean up error status messages that were causing some confusion in
      PHY and FCoE setup error reports.

      Mitch updates the virtual channel interface to prepare for the x722 device
      and other future devices, so that the VF driver can report what its
      capable of supporting to the PF driver.  Updates the i40evf driver to
      handle resets like Core or EMP resets, where the device is reinitialized
      and the VF will not get the same VSI.

      Jesse updates the i40e and i40evf driver to use the kernel BIT() and
      BIT_ULL() macros.

      cpufreq: Remove cpufreq_rwsem

      cpufreq_rwsem was introduced in commit 6eed9404ab3c4 ("cpufreq: Use
      rwsem for protecting critical sections) in order to replace
      try_module_get() on the cpu-freq driver. That try_module_get() worked
      well until the refcount was so heavily used that module removal became
      more or less impossible.

      Though when looking at the various (undocumented) protection
      mechanisms in that code, the randomly sprinkeled around cpufreq_rwsem
      locking sites are superfluous.

      The policy, which is acquired in cpufreq_cpu_get() and released in
      cpufreq_cpu_put() is sufficiently protected already.

        cpufreq_cpu_get(cpu)
          /* Protects against concurrent driver removal */
          read_lock_irqsave(&cpufreq_driver_lock, flags);
          policy = per_cpu(cpufreq_cpu_data, cpu);
          kobject_get(&policy->kobj);
          read_unlock_irqrestore(&cpufreq_driver_lock, flags);

      The reference on the policy serializes versus module unload already:

        cpufreq_unregister_driver()
          subsys_interface_unregister()
            __cpufreq_remove_dev_finish()
              per_cpu(cpufreq_cpu_data) = NULL;
        cpufreq_policy_put_kobj()

      If there is a reference held on the policy, i.e. obtained prior to the
      unregister call, then cpufreq_policy_put_kobj() will wait until that
      reference is dropped. So once subsys_interface_unregister() returns
      there is no policy pointer in flight and no new reference can be
      obtained. So that rwsem protection is useless.

      The other usage of cpufreq_rwsem in show()/store() of the sysfs
      interface is redundant as well because sysfs already does the proper
      kobject_get()/put() pairs.

      That leaves CPU hotplug versus module removal. The current
      down_write() around the write_lock() in cpufreq_unregister_driver() is
      silly at best as it protects actually nothing.

      The trivial solution to this is to prevent hotplug across
      cpufreq_unregister_driver completely.

      toshiba_acpi: Add /dev/toshiba_acpi device

      There were previous attempts to "merge" the toshiba SMM module to the
      toshiba_acpi one, they were trying to imitate what the old toshiba
      module does, however, some models (TOS1900 devices) come with a
      "crippled" implementation and do not provide all the "features" a
      "genuine" Toshiba BIOS does.

      This patch adds a new device called toshiba_acpi, which aim is to
      enable userspace to access the SMM on Toshiba laptops via ACPI calls.

      Creating a new convenience _IOWR command to access the SCI functions
      by opening/closing the SCI internally to avoid buggy BIOS, while at
      the same time providing backwards compatibility.

      Older programs (and new) who wish to access the SMM on newer models
      can do it by pointing their path to /dev/toshiba_acpi (instead of
      /dev/toshiba) as the toshiba.h header was modified to reflect these
      changes as well as adds all the toshiba_acpi paths and command,
      however, it is strongly recommended to use the new IOCTL for any
      SCI command to avoid any buggy BIOS.

      handled TOS620X devices accordingly.

      This patch adapts the code to show the hotkey values of TOS1900
      devices too, and in case some programs are still using that interface,
      hotkeys reporting should now work on these devices.

      Staging: most: add MOST driver's core module

      This patch adds the core module of the MOST driver to the kernel's driver
      staging area. This module is part of the MOST driver and handles the
      configuration interface in sysfs, the buffer management and the data
      routing.

      MOST defines the protocol, hardware and software layers necessary to allow
      for the efficient and low-cost transport of control, real-time and packet
      data using a single medium (physical layer). Media currently in use are
      fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST
      also supports various speed grades up to 150 Mbps.
      For more information on MOST, visit the MOST Cooperation website:
      www.mostcooperation.com.

      Cars continue to evolve into sophisticated consumer electronics platforms,
      increasing the demand for reliable and simple solutions to support audio,
      video and data communications. MOST can be used to connect multiple
      consumer devices via optical or electrical physical layers directly to one
      another or in a network configuration. As a synchronous network, MOST
      provides excellent Quality of Service and seamless connectivity for
      audio/video streaming. Therefore, the driver perfectly fits to the mission
      of Automotive Grade Linux to create open source software solutions for
      automotive applications.

      The driver consists basically of three layers. The hardware layer, the
      core layer and the application layer. The core layer consists of the core
      module only. This module handles the communication flow through all three
      layers, the configuration of the driver, the configuration interface
      representation in sysfs, and the buffer management.
      For each of the other two layers a selection of modules is provided. These
      modules can arbitrarily be combined to meet the needs of the desired
      system architecture. A module of the hardware layer is referred to as an
      HDM (hardware dependent module). Each module of this layer handles exactly
      one of the peripheral interfaces of a network interface controller (e.g.
      USB, MediaLB, I2C). A module of the application layer is referred to as an
      AIM (application interfacing module). The modules of this layer give 
access
      to MOST via one the following ways: character devices, ALSA, Networking or
      V4L2.

      To physically access MOST, an Intelligent Network Interface Controller
      (INIC) is needed. For more information on available controllers visit:
      www.microchip.com

      staging: unisys: visornic - prevent NETDEV WATCHDOG timeouts after IO 
recovery

      After IO partition recovery, it was possible to get into a situation where
      a visornic device would repeatedly report:

          NETDEV WATCHDOG: eth0 (): transmit queue 0 timed out

      The actual problem would affect any visornic device that was rapidly
      transmitting at the same time the IO partition was being recovered. Once
      you hit the problem, the only way to resume use of the nic would be to
      reboot the Linux client partition.

      The problem was caused by chstat.sent_xmit and chstat.got_xmit_done NOT
      getting cleared during IO partition recovery. This is necessary because
      outstanding xmits would essentially be "abandoned" during such recovery.
      These fields are now cleared in virtnic_serverdown_complete().

      `devpriv->ao_timer` is used while an asynchronous command is running on
      the AO subdevice.  It also gets modified by the subdevice's `cmdtest`
      handler for checking new asynchronous commands,
      `usbduxsigma_ao_cmdtest()`, which is not correct as it's allowed to
      check new commands while an old command is still running.  Fix it by
      moving the code which sets up `devpriv->ao_timer` into the subdevice's
      `cmd` handler, `usbduxsigma_ao_cmd()`.

      Note that the removed code in `usbduxsigma_ao_cmdtest()` checked that
      `devpriv->ao_timer` did not end up less that 1, but that could not
      happen due because `cmd->scan_begin_arg` or `cmd->convert_arg` had
      already been range-checked.

      Also note that we tested the `high_speed` variable in the old code, but
      that is currently always 0 and means that we always use "scan" timing
      (`cmd->scan_begin_src == TRIG_TIMER` and `cmd->convert_src == TRIG_NOW`)
      and never "convert" (individual sample) timing (`cmd->scan_begin_src ==
      TRIG_FOLLOW` and `cmd->convert_src == TRIG_TIMER`).  The moved code
      tests `cmd->convert_src` instead to decide whether "scan" or "convert"
      timing is being used, although currently only "scan" timing is
      supported.

      spi: davinci: Set prescale value based on register value

      Within davinci_spi_get_prescale() the prescale has two meanings. First one
      being the calculated prescale value and then at the end translates it to 
the
      prescale value that will be written to the SPI register.

      At first glance this can be confusing especially when comparing the 
minimum
      prescale value against what is seen in the TRM.

      To simplify things make it clear that the calculated prescale value will 
always
      be based on the value that will be written into the SPI register.

      ath10k: extend struct htt_mgmt_tx_dec for qca99x0

      HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
      4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
      rate mgmt frame has to go out in the air. It's an optional parameter,
      setting this field to zero will force firmware to choose auto rate
      and send the frame out.

      Those 4 byte info is missed out in the current code and 10.4 firmware
      ended up reading some junk in those 4 byte and sometime malfunctioning.

      Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
      will not process those four byte. So, adding 4 byte at the end of
      struct htt_mgmt_tx_desc will not create any impact on other chipset.

      ath10k: add support for qca99x0 Rx descriptors

      QCA99X0 chip has an extra 4 bytes in rx_msdu_start,
      20 bytes in rx_msdu_end and 20 bytes in rx_ppdu_end structure
      which are used in htt_rx_desc and HTT Rx ring offset setup.
      This is necessary for correct Rx for QCA99X0 or Rx descriptors
      will be overwritten and corrupted.

      With this patch QCA988X and QCA6174 will have extra 44 bytes

      ath10k: update tx path to support QCA99X0

      Since QCA99X0 uses fragmentation descriptor differently from
      other ones on tx path, we need to handle it separately.

      QCA99X0 is using 48 bits for address and 16 bits for length
      out of 2 dword and each values have to be programmed by frag
      desc base addr + msdu id, so that hardware can retrieve
      corresponding frag data.

      ath10k: delay device access after cold reset

      It is observed that during cold reset pcie access right
      after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
      Data Bus Error and system hard lockup. The reason
      for bus error is that pcie needs some time to get
      back to stable state for any transaction during cold reset. Add
      delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
      to fix this issue. This patch is tested on QCA988X. This is
      also tested on QCA99X0 which is WIP.

      target: Return descriptor format sense data in case the LU spans 64bit

      In case a LU spans 64bit sectors, fixed size sense data information
      field is only 32 bits which means the sector information will be 
truncated.

      Thus, if the LU spans 64bit sectors, use descriptor format sense data to
      correctly report sector information.

      - Add Carrizo support for amdkfd, using the new amdgpu driver as the 
relevant
        kgd. The support includes interfaces with amdgpu both for gfx7 (Kaveri) 
and
        gfx8 (Carrizo). However, gfx7 interface is used for debugging purposes 
only,
        so amdkfd defaults to using radeon when Kaveri is installed.

      I would like to note that no new IOCTLs are being introduced, and there 
is no
      change in the current IOCTLs, as they are suited both for gfx7 and gfx8.

      ARM: OMAP2+: PRCM and hwmod changes for v4.3

      This series adds:

      - I/O wakeup support for AM43xx
      - register lock and unlock support to the hwmod code (needed for the RTC
        IP blocks on some chips)
      - several fixes for sparse warnings and an unnecessary null pointer test
      - a DRA7xx clockdomain configuration workaround, to deal with some

      Since I do not have an AM43xx or DRA7xx device, I can't test on those
      platforms.

      perf: Add PERF_RECORD_SWITCH to indicate context switches

      There are already two events for context switches, namely the tracepoint
      sched:sched_switch and the software event context_switches.
      Unfortunately neither are suitable for use by non-privileged users for
      the purpose of synchronizing hardware trace data (e.g. Intel PT) to the
      context switch.

      Tracepoints are no good at all for non-privileged users because they
      need either CAP_SYS_ADMIN or /proc/sys/kernel/perf_event_paranoid <= -1.

      On the other hand, kernel software events need either CAP_SYS_ADMIN or
      /proc/sys/kernel/perf_event_paranoid <= 1.

      Now many distributions do default perf_event_paranoid to 1 making
      context_switches a contender, except it has another problem (which is
      also shared with sched:sched_switch) which is that it happens before
      perf schedules events out instead of after perf schedules events in.
      Whereas a privileged user can see all the events anyway, a
      non-privileged user only sees events for their own processes, in other
      words they see when their process was scheduled out not when it was
      scheduled in. That presents two problems to use the event:

      1. the information comes too late, so tools have to look ahead in the
         event stream to find out what the current state is

      2. if they are unlucky tracing might have stopped before the
         context-switches event is recorded.

      This new PERF_RECORD_SWITCH event does not have those problems
      and it also has a couple of other small advantages.

      It is easier to use because it is an auxiliary event (like mmap, comm
      and task events) which can be enabled by setting a single bit. It is
      smaller than sched:sched_switch and easier to parse.

      To make the event useful for privileged users also, if the
      context is cpu-wide then the event record will be
      PERF_RECORD_SWITCH_CPU_WIDE which is the same as
      PERF_RECORD_SWITCH except it also provides the next or
      previous pid/tid.

      perf tools: Stop copying kallsyms into the perf.data file header

      Since we now ask libtraceevent, the only user of this payload, to use
      perf's symbol resolution routines, there is no need to carry about
      ~4.5MB per perf.data when we can get it from one of the places the perf
      symbol resolution looks for that symtab (debuginfo, ~/.debug/,
      /proc/kallsyms, --symfs, etc), using the kernel and modules build-ids to
      make sure the right table is used.

      but that can be achieved using the symbol resolving routines we have
      in symbols.c, and that are used elsewhere in tools/perf.

      So, do just like 'perf trace' did and ask libtraceevent to use perf's
      symbol resolution routines.

      The next step is to just skip whatever kallsyms data is embedded in
      older perf.data files and finally to stop storing kallsyms in the perf
      data file, as the 20-bytes build-id stored in perf.data's header is
      enough to find out the right symtab (be it ELF, kcore, kallsyms, etc) to
      use.

      pty: Add debug message for ptmx open

      Opens of /dev/ptmx don't use tty_open() so debug messages are
      not printed for those opens; print a debug message with the
      open count (which must always be 1) if TTY_DEBUG_HANGUP is defined.

      NB: Each tty core source file undefs support for debug messages.
      The relevant source file must be patched/edited to enable these
      messages.

      tools lib traceevent: Allow setting an alternative symbol resolver

      The perf tools have a symbol resolver that includes solving kernel
      symbols using either kallsyms or ELF symtabs, and it also is using
      libtraceevent to format the trace events fields, including via
      subsystem specific plugins, like the "timer" one.

      To solve fields like "timer:hrtimer_start"'s "function", libtraceevent
      needs a way to map from its value to a function name and addr.

      This patch provides a way for tools that already have symbol resolving
      facilities to ask libtraceevent to use it when needing to resolve
      kernel symbols.

      tty/serial: at91: use 32bit writes into TX FIFO when DMA is enabled

      For now this improvement is only used with TX DMA transfers. The data
      width must be set properly when configuring the DMA controller. Also
      the FIFO configuration must be set to match the DMA transfer data
      width:
      TXRDYM (Transmitter Ready Mode) and RXRDYM (Receiver Ready Mode) must
      be set into the FIFO Mode Register. These values are used by the
      USART to trigger the DMA controller. In single data mode they are not
      used and should be reset to 0.
      So the TXRDYM bits are changed to FOUR_DATA; then USART triggers the
      DMA controller when at least 4 data can be written into the TX FIFO
      througth the THR. On the other hand the RXRDYM bits are left unchanged
      to ONE_DATA.

      Atmel eXtended DMA controller allows us to set a different data width
      for each part of a scatter-gather transfer. So when calling
      dmaengine_slave_config() to configure the TX path, we just need to set
      dst_addr_width to the maximum data width. Then DMA writes into THR are
      split into up to two parts. The first part carries the first data to
      be sent and has a length equal to the greatest multiple of 4 (bytes)
      lower than or equal to the total length of the TX DMA transfer. The
      second part carries the trailing data (up to 3 bytes). The first part
      is written by the DMA into THR using 32 bit accesses, whereas 8bit
      accesses are used for the second part.

      tty/serial: at91: add support to FIFOs

      Depending on the hardware, TX and RX FIFOs may be available. The RX
      FIFO can avoid receive overruns, especially when DMA transfers are
      not used to read data from the Receive Holding Register. For heavy
      system load, The CPU is likely not be able to fetch data fast enough
      from the RHR.

      In addition, the RX FIFO can supersede the DMA/PDC to control the RTS
      line when the Hardware Handshaking mode is enabled. Two thresholds
      are to be set for that purpose:
      - When the number of data in the RX FIFO crosses and becomes lower
        than or equal to the low threshold, the RTS line is set to low
        level: the remote peer is requested to send data.
      - When the number of data in the RX FIFO crosses and becomes greater
        than or equal to the high threshold, the RTS line is set to high
        level: the remote peer should stop sending new data.
      - low threshold <= high threshold
      Once these two thresholds are set properly, this new feature is
      enabled by setting the FIFO RTS Control bit of the FIFO Mode Register.

      FIFOs also introduce a new multiple data mode: the USART works either
      in multiple data mode or in single data (legacy) mode.

      If MODE9 bit is set into the Mode Register or if USMODE is set to
      either LIN_MASTER, LIN_SLAVE or LON_MODE, FIFOs operate in single
      data mode. Otherwise, they operate in multiple data mode.

      In this new multiple data mode, accesses to the Receive Holding
      Register or Transmit Holding Register slightly change.

      Since this driver implements neither the 9bit data feature (MODE9 bit
      set into the Mode Register) nor LIN modes, the USART works in
      multiple data mode whenever FIFOs are available and enabled. We also
      assume that data are 8bit wide.

      In single data mode, 32bit access CAN be used to read a single data
      from RHR or write a single data into THR.
      However in multiple data mode, a 32bit access to RHR now allows us to
      read four consecutive data from RX FIFO. Also a 32bit access to THR
      now allows to write four consecutive data into TX FIFO. So we MUST
      use 8bit access whenever only one data have to be read/written at a
      time.

      ARM: at91/dt: add a new DT property to support FIFOs on Atmel USARTs

      This patch adds a new DT property, "atmel,fifo-size", to enable and set
      the maximum number of data the RX and TX FIFOs can store on FIFO capable
      USARTs.

      Please be aware that the VERSION register can not be used to guess the
      size of FIFOs. Indeed, for a given hardware version, the USARTs can be
      integrated on Atmel SoCs with different FIFO sizes. Also the
      "atmel,fifo-size" property is optional as older USARTs don't embed FIFO at
      all.

      Besides, the FIFO size can not be read or guessed from other registers:
      When designing the FIFO feature, no dedicated registers were added to
      store this size. Unsed spaces in the I/O register range are limited and
      better reserved for future usages. Instead, the FIFO size of each
      peripheral is documented in the programmer datasheet.

      Finally, on a given SoC, there can be several instances of USART with
      different FIFO sizes. This explain why we'd rather use a dedicated DT
      property than use the "compatible" property.

      serial: imx: reduce irq-latency after rx overflow

      To prevent problems with interrupt latency, and due to the fact, that
      the error will be counted anyway (icount.overrun), the dev_err is simply
      removed.

      Background:
      If an rx-fifo overflow occurs a dev_err message was called in interrupt
      context. Since dev_err messages are written to console in a synchronous 
way
      (unbuffered), and console may be a serial terminal, this leads to a
      highly increased interrupt-latency (several milliseconds).
      As a result of the high latency more rx-fifo overflows will happen, and
      therefore a feedback loop of errors is created.

      serial: sirf: workaround rx process to avoid possible data loss

      when UART works in DMA mode and left bytes in rx fifo less than
      a dma transfer unit, DMA engine can't transfer the bytes out
      to rx DMA buffer. so it need a way to fetch them out and
      flush them into tty buffer in time.

      in the above case, we want UART switch from DMA mode to PIO mode and
      fetch && flush bytes into tty layer buffer until rxfifo become empty,
      after that done let UART switch from PIO mode back to DMA mode.
      (record as method1)

      method1 result in the next receive result wrong. for example in PIO part
      of method1, we fetched && pushed X1...X3 bytes, when UART rxfifo newly
      received Y1...Y4 bytes, UART trigger a DMA unit transfer, the DMA unit's
      content is X1...X3Y1 and rxfifo fifo status is empty, so X1X2X3 pushed
      twice by PIO way and DMA way also the bytes Y2Y3Y4 missed. add rxfifo
      reset operation before UART switch back to DMA mode would resolve the
      issue. ([method1 + do fifo reset] record as method2)

      before the commit, UART driver use method2. but methd2 have a risk of
      data loss, as if UART's shift register receive a complete byte and
      transfer it into rxfifo before rxfifo reset operation the byte will
      loss.

      UART and USP have the similar bits 
CLEAR_RX_ADDR_EN(uart)/FRADDR_CLR_EN(usp),
      When found UART controller changing I/O to DMA mode, UART controller
      clears the two low bits of read point (rx_fifo_addr[1:0]).
      when enable the bit + method1(record as method3), in above example
      the DMA unit's content is X1...X3Y1 and there are Y2Y3Y4 in rxfifo by
      experiment, we just push bytes in rx DMA buffer.

      BTW, the workaround works only for UART receive DMA channel use SINGLE
      DMA mode.

      The implementation of cris_console_device() is exactly the same as

      serial: 8250_omap: Remove auto-IXON flow control

      OMAP h/w-assisted IXON flow control is borked. The transmitter becomes
      stuck if XON is never received; clearing the fifos or resetting the
      rx flow control bits has no effect.

      Remove auto-IXANY as well, since without auto-IXON, it has no purpose.

      serial: 8250_omap: workaround module disable errata on dra7x SoCs

      Due to Advisory 21 as documented in AM437x errata document,
      UART module cannot be disabled once DMA is used. The only
      workaround is to softreset the module before disabling it.

      DRA7x UARTs are compatible to AM437x UARTs in terms of
      this errata and prescribed workaround.

      Enable usage of workaround for this errata on DRA7x SoCs.

      serial: 8250_omap: workaround errata around idling UART after using DMA

      AM335x, AM437x and DRA7x SoCs have an errata[1] due to which UART
      cannot be idled after it has been used with DMA.

      OMAP3 has a similar sounding errata which has been worked around
      in a2fc36613ac1af2e9 ("ARM: OMAP3: Use manual idle for UARTs
      because of DMA errata"). But the workaround used there does not
      apply to AM335x, AM437x SoCs.

      After using DMA, the UART module on these SoCs must be soft reset
      to go to idle.

      This patch implements that errata workaround. It is expected that
      UART will be used with DMA so no explicit check for DMA usage
      has been added for errata applicability.

      MDR1 register needs to be restored right after soft-reset because
      "UART mode" must be set in that register for module wake-up on AM335x
      to work. As a result, SCR register is now used to determine if
      context was lost during sleep.

      serial: 8250_omap: introduce "ti,am3352-uart" compatible property

      Use of of_machine_is_compatible() for handling AM335x specific
      "DMA kick" quirk in 8250_omap driver makes it ugly to extend the
      quirk for other platforms. Instead use a new compatible.

      The new compatible will also make it easier to take care of
      other quirks on AM335x and like SoCs.

      In order to not break backward DTB compatibility for users of
      8250_omap driver on AM335x based boards, existing use of
      of_machine_is_compatible() has not been removed.

      serial: 8250_omap: fix kernel crash in suspend-to-ram

      omap_device infrastructure has a suspend_noirq hook which
      runtime suspends all devices late in the suspend cycle (see
      _od_suspend_noirq() in arch/arm/mach-omap2/omap_device.c)

      This leads to a NULL pointer exception in 8250_omap driver
      since by the time omap8250_runtime_suspend() is called, 8250_dma
      driver has already set rxchan to NULL via serial8250_release_dma().

      Make an explicit check to see if rxchan is NULL in
      runtime_{suspend|resume} hooks to fix this.

      tty: Convert use of __constant_htons to htons

      In little endian cases, macro htons unfolds to __swab16 which
      provides special case for constants. In big endian cases,
      __constant_htons and htons expand directly to the same expression.
      So, replace __constant_htons with htons with the goal of getting
      rid of the definition of __constant_htons completely.

      The semantic patch that performs this transformation is as follows:

      @@expression x;@@

      - __constant_htons(x)
      + htons(x)

      ACPICA commit 310e0ae1c4730f4dadc80125125099ab76851499

      arg_types in struct acpi_db_method_info is only referenced by 
ACPI_DEBUGGER.

      This patch only affects ACPICA debugger which is only used by a non-kernel
      tool - acpiexec, so Linux kernel is currently not affected by this patch.

      ACPICA: Executer: Add interpreter tracing mode for method tracing facility

      ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b

      The acpi_debug_trace() is the mechanism known as ACPI method tracing that 
is
      used by Linux as ACPICA debugging message reducer. This facility can be
      controlled through Linux ACPI subsystem - /sys/module/acpi/parameters.
      This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace
      logs in the kernel dmesg output.

      This patch enhances acpi_debug_trace() to make it not only a message 
reducer,
      but a real tracer to trace AML interpreter execution. Note that in 
addition
      to the AML tracer enabling, this patch also updates the facility with the
      following enhancements:
      1. Allow a full path to be specified by the acpi_debug_trace() API.
      2. Allow any method rather than just the entrance of 
acpi_evaluate_object()
         to be traced.
      3. All interpreter ACPI_LV_TRACE_POINT messages are collected for
         ACPI_EXECUTER layer.

      The Makefile of drivers/acpi/acpica is also updated to include exdebug.o
      and the duplicated stubs are removed after that.

      Note that since this patch has enhanced the method tracing facility, Linux
      need also be updated after applying this patch. Lv Zheng.

      ACPICA: Dispatcher: Add trace support for interpreter

      ACPICA commit 71299ec8b49054daace0df50268e8e055654ca37

      This patch adds trace point at the following point:
       1. Begin/end of a control method execution;
       2. Begin/end of an opcode execution.

      The trace point feature can be enabled by defining ACPI_DEBUG_OUTPUT
      and specifying a debug level that includes ACPI_LV_TRACDE_POINT and the
      debug layers that include ACPI_PARSER and ACPI_DISPACTCHER.

      In order to make aml_op_name of union acpi_parse_object usable for 
tracer, it is
      enabled for ACPI_DEBUG_OUTPUT in this patch. Lv Zheng.

      ACPICA: Dispatcher: Move stack traversal code to dispatcher

      ACPICA commit c8275e243b58fd4adfc0362bd704af41ed14bc75

      This patch moves parts of acpi_dm_dump_method_info() to the dispatcher

      This patch also makes the new function dependent on ACPI_DEBUG_OUTPUT
      compile-stage definition so that it can be used by the trace facility.

      acpi_dm_dump_method_info() traverses method stack when an exception is
      encountered. Such traversal is needed to support method tracing for the
      exceptions. When an exception is encountered, the end indications of the
      aborted methods should be logged in order not to break the user space
      analysis tool. Lv Zheng.

      ACPICA: Namespace: Add function to directly return normalized full path

      ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea

      This patch adds functions to return normalized full path instead of
      "external path". The external path contains trailing "_" for each
      name segment while the normalized full path doesn't contain the
      trailing "_".

      Currently this function is used by the method tracing users to specify a
      none trailing "_" attached name path. Lv Zheng.

      Note that we need to validate and switch all Linux kernel acpi_get_name()
      users to use the new name type before removing the old name type from

      ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address 
assignments

      ACPICA commit afb52611dbe7403551f93504d3798534f5c343f4

      This patch cleans up the code of assigning the AML address to the
      union acpi_operand_object.

      The idea behind this cleanup is:
      The AML address of the union acpi_operand_object should always be 
determined at
      the point where the object is encountered. It should be started from the
      first byte of the object. For example, the opcode of the object, the name
      string of the user_term object, or the first byte of the packaged object
      (where a pkg_length is prefixed). So it's not cleaner to have it assigned
      here and there in the entire ACPICA source tree.

      There are some special cases for the internal opcodes, before cleaning up
      the internal opcodes, we should also determine the rules for the AML
      addresses of the internal opcodes:
      1. INT_NAMEPATH_OP: the address of the first byte for the name_string.
      2. INT_METHODCALL_OP: the address of the first byte for the name_string.
      3. INT_BYTELIST_OP: the address of the first byte for the byte_data list.
      4. INT_EVAL_SUBTREE_OP: the address of the first byte for the
                              Region/Package/Buffer/bank_field/Field arguments.
      5. INT_NAMEDFIELD_OP: the address to the name_seg.
      6. INT_RESERVEDFIELD_OP: the address to the 0x00 prefix.
      7. INT_ACCESSFIELD_OP: the address to the 0x01 prefix.
      8. INT_CONNECTION_OP: the address to the 0x02 prefix.
      9: INT_EXTACCESSFIELD_OP: the address to the 0x03 prefix.
      10.INT_RETURN_VALUE_OP: the address of the replaced operand.
      11.computational_data: the address to the
                            Byte/Word/Dword/Qword/string_prefix.

      Before cleaning up the internal root scope of the aml_walk, turning it 
into
      the term_list, we need to remember the aml_start address as the "Aml"
      attribute for the union acpi_operand_object created by 
acpi_ps_create_scope_op().

      Finally, we can delete some redundant AML address assignment in psloop.c.

      ACPICA: Parser: Cleanup aml_offset in union acpi_operand_object

      ACPICA commit 61b360074fde2bb8282722579410f5d1fb12f84d

      This patch converts aml_offset in union acpi_operand_object to AML 
address.

      AML offset is actually only used by the debugger, using AML address is 
more
      direct and efficient during the parsing stage so that we don't need to
      calculate the offset during the parsing stage and will not have
      difficulities in converting it into other offset attributes.

      Sometimes, aml_offset is not an indication of the offset from the table
      header but the offset from the entry of a list of terms, which requires
      additional efforts to convert it into an offset from the table header. By
      using AML address directly, there is no such difficulty.
      Thus this patch also deletes a logic in disassembler that is trying to
      convert the aml_offset from
        "offset from the start address of Method/Package/Buffer"
      into the
        "offset from the start address of the ACPI table"
      (Sample code deletion can be seen in acpi_dm_deferred_parse(), but the
      function is not in the Linux kernel). Lv Zheng.

      ACPICA: Parser: Cleanup aml_offset in struct acpi_walk_state

      ACPICA commit d254405814495058276c0c2f9d96794d15a6c91c

      This patch converts aml_offset in struct acpi_walk_state to AML address.

      AML offset is actually only used by the debugger, using AML address is 
more
      direct and efficient during the parsing stage so that we don't need to
      calculate it during the parsing stage.

      On the other hand, we can see several issues in the current parser logic
      around the aml_offset:
      1. union acpi_operand_object.Common.aml_offset is redundantly assigned in
         acpi_ps_parse_loop().
      2. aml_offset is not an indication of the offset from the table header but
         the offset from the entry of a list of objects. Sometimes, it indicates
         an entry for a Method/Package/Buffer, which makes it difficult to be
         reversely calculated to a table header offset.
      3. When being used with method tracers (for example, Linux function 
trace),
         it's better to have AML address logged instead of the AML offset 
because
         the address is the only attribute that can uniquely identify the 
opcode.
      This patch is required to solve the above issues. Lv Zheng.

      iio: fix drivers that consider 0 as a valid IRQ in client->irq

      Since patch "i2c / ACPI: Use 0 to indicate that device does not have
      interrupt assigned" [1], 0 is not a valid i2c client irq anymore, so
      change all driver's checks accordingly.

      The same issue occurs when the device is instantiated via device tree
      with no IRQ, or from the i2c sysfs interface, even before the patch
      above.

      fs: Remove ext3 filesystem driver

      The functionality of ext3 is fully supported by ext4 driver. Major
      distributions (SUSE, RedHat) already use ext4 driver to handle ext3
      filesystems for quite some time. There is some ugliness in mm resulting
      from jbd cleaning buffers in a dirty page without cleaning page dirty
      bit and also support for buffer bouncing in the block layer when stable
      pages are required is there only because of jbd. So let's remove the
      ext3 driver. This saves us some 28k lines of duplicated code.

      Currently when some error happened in ->acquire_dquot(), dqget() just

      run quotaoff and so was generally silently ignored. However
      ->acquire_dquot() can fail because of ENOSPC or EIO in which case user

      ASoC: rl6231: add pll preset table

      Currently, rl6231_pll_calc provide a working PLL parameters for
      given freq_in and freq_out. However, in some cases it is not the
      perfect parameter. For example if freq_in = 19200000 and freq_out
       = 24576000, the calculated parameter will gengrate 24.5647 MHz
      which is not exactly the same as what we need. But the PLL can
      output 24.576 MHz as exactly what we expect if we set the best
      PLL parameter.
      To improve it, we put the best match parameters in a preset table.
      We can search the preset table first, if there is no preset parameter
      for the given freq_in and freq_out, we can still calculate a working
      PLL parameter.

      rtc: st: Update IP layout information to include Clocksource

      Initial submission adding support for this IP only included Watchdog and
      the Real-Time Clock.  Now the third (and final) device is enabled this
      trivial patch is required to update the comment in the RTC driver to
      encompass Clocksource.

      PCI: Call pci_read_bridge_bases() from core instead of arch code

      When we scan a PCI bus, we read PCI-PCI bridge window registers with
      pci_read_bridge_bases() so we can validate the resource hierarchy.  Most
      architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but
      PCI-PCI bridges are not arch-specific, so this doesn't need to be in
      arch-specific code.

      Call pci_read_bridge_bases() directly from the PCI core instead of from
      arch code.

      For alpha and mips, we now call pci_read_bridge_bases() always; previously
      we only called it if PCI_PROBE_ONLY was set.

      Before:
         connSlaveLatency <= ((connSupervisionTimeout / connIntervalMax) - 1)

      After:
         connSlaveLatency <= ((connSupervisionTimeout / (connIntervalMax*2)) - 
1)

      Bluetooth: __l2cap_wait_ack() add defensive timeout

      Add a timeout to prevent the do while loop running in an
      infinite loop. This ensures that the channel will be
      instructed to close within 10 seconds so prevents
      l2cap_sock_shutdown() getting stuck forever.

      Returns -ENOLINK when the timeout is reached. The channel
      will be subequently closed and not all data will be ACK'ed.

      Bluetooth: Make __l2cap_wait_ack more efficient

      Use chan->state instead of chan->conn because waiting
      for ACK's is only possible in the BT_CONNECTED state.
      Also avoids reference to the conn structure so makes
      locking easier.

      Only call __l2cap_wait_ack() when the needed condition
      of chan->unacked_frames > 0 && chan->state == BT_CONNECTED
      is true and convert the while loop to a do while loop.

      __l2cap_wait_ack() change the function prototype to
      pass in the chan variable as chan is already available
      in the calling function l2cap_sock_shutdown(). Avoids
      locking issues.

      Bluetooth: L2CAP ERTM shutdown protect sk and chan

      During execution of l2cap_sock_shutdown() which might
      sleep, the sk and chan structures can be in an unlocked
      condition which potentially allows the structures to be
      freed by other running threads. Therefore, there is a
      possibility of a malfunction or memory reuse after being
      freed.

      Keep the sk and chan structures alive during the
      execution of l2cap_sock_shutdown() by using their
      respective hold and put functions. This allows the structures
      to be freeable at the end of l2cap_sock_shutdown().

      mac802154: cfg: add suspend and resume callbacks

      This patch introduces suspend and resume callbacks to mac802154. When
      doing suspend we calling the stop driver callback which should stop the
      receiving of frames. A transceiver should go into low-power mode then.
      Calling resume will call the start driver callback, which starts receiving
      again and allow to transmit frames.

      This was tested only with the fakelb driver and a qemu vm by doing the
      following commands:

      echo "devices" > /sys/power/pm_test
      echo "freeze" > /sys/power/state

      issues for setting an IPv6 address to a 6LoWPAN interface. The issues
      was solved by modprobe the ipv6 module before. To avoid such user issues
      we try to request the ipv6 module when the 6LoWPAN module is loaded.

      mac802154: add llsec address update workaround

      This patch adds a workaround for using the new nl802154 netlink
      interface with the old ieee802154 netlink interface togehter. The
      nl802154 currently supports no access for llsec layer, currently there
      are users outside which are using both interfaces at the same time. This
      patch adds a necessary call when addresses are updated.

      PCI: designware: Don't complain missing *config* reg space if va_cfg0 is 
set

      Currently on Keystone SoCs, we always complain:

        keystone-pcie 21021000.pcie: missing *config* reg space

      Keystone uses an older version of DesignWare hardware that doesn't have
      ATU support.  So va_cfg0_base and va_cfg1_base are already set up in
      ks_dw_pcie_host_init() before calling dw_pcie_host_init(), and they point
      to the remote config space address va (both same for Keystone).  Add a
      check to avoid this boot noise on Keystone.

      regulator: tps6586x: silence pointer-to-int-cast

      of_regulator_match.driver_data is (void *).  tps6586x uses it to store an
      anonymous enum value (those TPS6586X_ID_ values).

      Later, it tries to extract the ID by casting directly to an int, which is 
a
      no-no ([-Wpointer-to-int-cast]):

      drivers/regulator/tps6586x-regulator.c: In function 
'tps6586x_parse_regulator_dt':

         id = (int)tps6586x_matches[i].driver_data;
              ^

      Instead of casting to int, uintptr_t is better suited for receiving and
      comparing integers extracted from void *.  This is especially true on
      64-bit systems where sizeof(void *) != sizeof(int).

      netfilter: fix possible removal of wrong hook

      nf_unregister_net_hook() uses the nf_hook_ops fields as tuple to look up 
for
      the corresponding hook in the list. However, we may have two hooks with 
exactly
      the same configuration.

      This shouldn't be a problem for nftables since every new chain has an 
unique
      priv field set, but this may still cause us problems in the future, so 
better
      address this problem now by keeping a reference to the original 
nf_hook_ops
      structure to make sure we delete the right hook from 
nf_unregister_net_hook().

      ext4, jbd2: add REQ_FUA flag when recording an error in the superblock

      When an error condition is detected, an error status should be recorded 
into
      superblocks of EXT4 or JBD2. However, the write request is submitted now
      without REQ_FUA flag, even in "barrier=1" mode, which is followed by
      panic() function in "errors=panic" mode. On mobile devices which make
      whole system reset as soon as kernel panic occurs, this write request
      containing an error flag will disappear just from storage cache without
      written to the physical cells. Therefore, when next start, even forever,
      the error flag cannot be shown in both superblocks, and e2fsck cannot fix
      the filesystem problems automatically, unless e2fsck is executed in
      force checking mode.

      This driver fully supports VF drivers using both the 1.0 and 1.1
      versions of the virtual channel API. However, VF drivers using

      Correct this by checking the VFs API version at the time that we

      so we can all get along.

      i40evf: handle big resets

      The most common type of reset that the VF will encounter is a PF reset
      that cascades down into a VF reset for each VF. In this case, the VF
      will always be assigned the same VSI and recovery is fairly simple.

      However, in the case of 'bigger' resets, such as a Core or EMP reset,
      when the device is reinitialized, it's probable that the VF will NOT get
      the same VSI. When this happens, the VF will not be able to recover, as
      it will continue to request resources for its original VSI.

      Add an extra state to the admin queue state machine so that the driver
      can re-request its configuration information at runtime. During reset
      recovery, set this bit in the aq_required field, and fetch the (possibly
      new) configuration information before attempting to bring the driver
      back up. Since the driver doesn't know what kind of reset it has
      encountered, this step is done even for a PF reset, but it doesn't hurt
      anything - it just gets the same VSI back.

      i40e: add VF capabilities to virtual channel interface

      To prepare for the changes coming up in the X722 device and future
      devices, the virtual channel interface has to change slightly. The VF
      driver can now report what its capable of supporting, which then informs
      the PF driver when it sends the configuration information back to the
      VF.

      A 1.1 VF driver on a 1.0 PF driver should not send its capabilities.
      Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect
      or depend upon receiving the VF capabilities.

      All other aspects of the API are unchanged.

      i40e/i40evf: Fix and refactor dynamic ITR code

      This patch changes the switch statement for dynamic interrupt throttling
      and adds a default case. With this patch, we check the latency setting
      instead of the current ITR settings and the included refactor improves
      performance.

      Without this patch, the ITR setting would never change dynamically, and
      there was no default.

      If a device sends its contacts across multiple reports (what Microsoft

      HID: wacom: Perform all event processing as part of report processing

      Since the HID subsystem doesn't provide a way to take action before 
'event'
      is called, we take a cue from hid-multitouch.c and add a pre-process step
      within the 'report' handler that performs the same function.

      ixgbevf: add support for reporting RSS key and hash table for X550

      This patch extends the reporting of the RSS key and hash table by
      adding support for X550 VFs. The difference is that X550 VFs have
      their own registers for RSS key and indirection table, so there is
      no need to query the PF.

      The RSS key and indirection table are stored in the adapter structure
      during the configuration of VFRSSRK and VFRETA which in turn can be
      used in ethtool for reporting.

      The logic for writing VFRETA is also changed to make sure that the
      indirection table is reported correctly.

      In addition this patch adds defines for the VFRETA entries and number
      of VFRSSRK registers as well as some whitespace cleanups.

      crypto: nx - make platform drivers directly register with crypto

      Remove the common 'platform' registration module, and move the crypto
      compression driver registration into each of the pSeries and PowerNV
      platform NX 842 drivers.  Change the nx-842.c code into simple common
      functions that each platform driver uses to perform constraints-based
      buffer changes, i.e. realigning and/or resizing buffers to match the
      driver's hardware requirements.

      The common 'platform' module was my mistake to create - since each
      platform driver will only load/operate when running on its own
      platform (i.e. a pSeries platform or a PowerNV platform), they can
      directly register with the crypto subsystem, using the same alg and
      driver name.  This removes unneeded complexity.

      powerpc: Use hardware RNG for arch_get_random_seed_* not arch_get_random_*

      The hardware RNG on POWER8 and POWER7+ can be relatively slow, since
      it can only supply one 64-bit value per microsecond.  Currently we
      read it in arch_get_random_long(), but that slows down reading from
      /dev/urandom since the code in random.c calls arch_get_random_long()
      for every longword read from /dev/urandom.

      Since the hardware RNG supplies high-quality entropy on every read, it
      matches the semantics of arch_get_random_seed_long() better than those
      of arch_get_random_long().  Therefore this commit makes the code use
      the POWER8/7+ hardware RNG only for arch_get_random_seed_{long,int}
      and not for arch_get_random_{long,int}.

      This won't affect any other PowerPC-based platforms because none of
      them currently support a hardware RNG.  To make it clear that the
      ppc_md function pointer is used for arch_get_random_seed_*, we rename
      it from get_random_long to get_random_seed.

      Fix this issue by introducing a new rtas_get_sensor_fast() function
      that does not use rtas_busy_delay() - and thus can only be used for
      sensors that do not cause a BUSY condition - known as "fast" sensors.

      The EPOW sensor is defined to be "fast" in sPAPR - mpe.

      KVM: svm: handle KVM_X86_QUIRK_CD_NW_CLEARED in svm_get_mt_mask

      We can disable CD unconditionally when there is no assigned device.
      KVM now forces guest PAT to all-writeback in that case, so it makes
      sense to also force CR0.CD=0.

      When there are assigned devices, emulate cache-disabled operation
      through the page tables.  This behavior is consistent with VMX
      microcode, where CD/NW are not touched by vmentry/vmexit.  However,
      keep this dependent on the quirk because OVMF enables the caches
      too late.

      KVM: nVMX: VMX instructions: add checks for #GP/#SS exceptions

      According to Intel SDM several checks must be applied for memory operands
      of VMX instructions.

      Long mode: #GP(0) or #SS(0) depending on the segment must be thrown
      if the memory address is in a non-canonical form.

      Protected mode, checks in chronological order:
      - The segment type must be checked with access type (read or write) taken
      into account.
        For write access: #GP(0) must be generated if the destination operand
                is located in a read-only data segment or any code segment.
        For read access: #GP(0) must be generated if if the source operand is
                located in an execute-only code segment.
      - Usability of the segment must be checked. #GP(0) or #SS(0) depending on 
the
        segment must be thrown if the segment is unusable.
      - Limit check. #GP(0) or #SS(0) depending on the segment must be
        thrown if the memory operand effective address is outside the segment
        limit.

      staging: unisys: Fix improper use of NETDEV_TX_BUSY

      Using NETDEV_TX_BUSY is tricky.  Its meant for situations where the error
      in question is transient and quickly resolved.  But the driver rarely is
      able to know that to a certainty.  And in the case of visornic, it just
      uses it without any care for that, in the hopes that it won't loose 
frames,
      even if the problem is that the skb is somehow malformed for the hardware.
      If we get one of those kinds of skbs, NETDEV_TX_BUSY will just cause us to
      spin, processing the same error over and over.

      Fix it by dropping the frame, stopping the queue where appropriate, and
      returning NETDEV_TX_OK

      As pointed out in a recent review, the num_visornic_open array didn't do
      anything useful, and it exposed a potential race in the visornic code that
      could arise while taking down a net interface while reading from the
      debugfs files. Fix that by removing the array entirely, and just iterating
      over all the registered netdevs in a given namespace, filtering on them
      having visornic ops (to identify which are ours), and having their queues
      not be stopped (identifying that they are up). This should prevent any 
oops
      conditions happening due to changing state in that array, and save us a
      bunch of code too.

      staging/comedi/drivers/usbduxsigma.c: added support for ehci drivers

      urb->interval is deprecated and thus I've changed the driver
      that it now always assumes interval=1 which means every frame
      in USB 1.1 and every uframe in USB 2.0. However we still need
      to have different sampling rates which are still multiples
      of the interval which is now transmitted to the firmware.
      The firmware transmits either zero length packets or none every (u)frame.
      This is checked in the completion handler and any packet
      at zero length is discarded so that comedi again sees the data
      coming in at the interval specified. This also then gives the ADC
      the necessary time to convert. For example 16 channels require
      about 700us and in this period no packet could be transmitted.
      In this case this is padded up to 1ms so that we have then 7 zero
      length packets and one packet with the ADC data.

      The reason for dropping these now rather than later is that now
      we can simply revert the patches in case of unexpected issues as
      we are not dropping any platform data at this point.

      This leaves us with only the following board-*.c files:

      BOARD                   REASON NEEDED
      board-ldp.c             Still used in RMKs boot test system
      board-rx51-*.c          Needs /proc/atags support for user space

      Once we have the n900 legacy user space issues sorted out for
      /proc/atags and system_rev, we can drop the remaining two
      board-*.c files. And then one merge window after that we can
      drop the legacy booting support assuming no unexpected issues
      are found.

      rcu: Don't disable CPU hotplug during OOM notifiers

      RCU's rcu_oom_notify() disables CPU hotplug in order to stabilize the
      list of online CPUs, which it traverses.  However, this is completely
      pointless because smp_call_function_single() will quietly fail if invoked
      on an offline CPU.  Because the count of requests is incremented in the
      rcu_oom_notify_cpu() function that is remotely invoked, everything works
      nicely even in the face of concurrent CPU-hotplug operations.

      Furthermore, in recent kernels, invoking get_online_cpus() from an OOM
      notifier can result in deadlock.  This commit therefore removes the
      call to get_online_cpus() and put_online_cpus() from rcu_oom_notify().

      scripts: Make checkpatch.pl warn on expedited RCU grace periods

      The synchronize_rcu_expedited() and synchronize_sched_expedited()
      expedited-grace-period primitives induce OS jitter, which can degrade

      on any patch adding them.

      Note that this patch does not warn on synchronize_srcu_expedited()
      because it does not induce OS jitter, courtesy of its otherwise
      much-maligned read-side memory barriers.

      rcu: Create a synchronize_rcu_mult()

      There have been several requests for a primitive that waits for
      grace periods for several RCU flavors concurrently, so this
      commit creates it.  This is a variadic macro, and you pass in
      the call_rcu() functions of the flavors of RCU that you wish to
      wait for.

      Note that you cannot pass in call_srcu() for two reasons: (1) This
      would result in a type mismatch and (2) You need to specify which
      srcu_struct you want to use.  Handle this by creating a wrapper
      function for your SRCU domain, for example:

        void call_srcu_mine(struct rcu_head *head, rcu_callback_t func)
        {
                call_srcu(&ss_mine, head, func);
        }

      You can then do something like this:

        synchronize_rcu_mult(call_srcu_mine, call_rcu, call_rcu_sched);

      rcu: Add RCU-sched flavors of get-state and cond-sync

      The get_state_synchronize_rcu() and cond_synchronize_rcu() functions
      allow polling for grace-period completion, with an actual wait for a
      grace period occurring only when cond_synchronize_rcu() is called too
      soon after the corresponding get_state_synchronize_rcu().  However,
      these functions work only for vanilla RCU.  This commit adds the
      get_state_synchronize_sched() and cond_synchronize_sched(), which provide
      the same capability for RCU-sched.

      cpufreq: acpi-cpufreq: Fix up the handling of cpb sysfs attribute

      The cpb sysfs attribute is only exposed by the ACPI cpufreq driver
      after a runtime check.  For this purpose, the driver keeps a NULL
      placeholder in its table of sysfs attributes and replaces the NULL
      with a pointer to an attribute structure if it decides to expose
      cpb.

      That is confusing, so make the driver set the pointer to the cpb
      attribute structure upfront and replace it with NULL if the
      attribute should not be exposed instead.

      PCI: iproc: Add arm64 support

      Add arm64 support to the iProc PCIe driver.

      Note that on arm32, bus->sysdata points to the arm32-specific pci_sys_data
      struct, and pci_sys_data.private_data contains the iproc_pcie pointer.
      For arm64, there's nothing corresponding to pci_sys_data, so we keep the
      iproc_pcie pointer directly in bus->sysdata.

      In addition, arm64 does IRQ mapping in pcibios_add_device(), so it doesn't
      need pci_fixup_irqs() as arm32 does.

      This patch series does several things - it updates the bnx2x FW into
      7.12.30 which both contains some small fixes as well as opening the door
      for several new features for the device - mainly vxlan/geneve offloads
      and vlan filtering offload.
      It then adds a new Multi-function mode [BD] which requires this FW in
      order to operate.

      In addition, this finally rebrands the driver from a 'broadcom' driver
      into a 'qlogic' driver [although it would still reside under Broadcom's
      tree in the kernel].

      in case their device contains a dump of a previous crash.

      bnx2x: Utilize FW 7.12.30

      This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:

       - Packets from a VF with pvid configured which were sent with a
         different vlan were transmitted instead of being discarded.

       - FCoE traffic might not recover after a failue while there's traffic
         to another function.

      In addition, this FW opens the door for the driver to implement several
      new features; Specifically, this enhances the device's support for
      encapsulated packets and will allow vxlan/geneve offloads to be added in
      the future, as well as vlan filtering offload.

      genirq/MSI: Reorginize struct msi_desc to prepare for support of generic 
MSI

      Reorganize struct msi_desc so it could be reused by other MSI
      drivers. We have the following layout now:

      struct msi_desc {
             /* Shared device/bus independent data */
             ...
             union {
                     /* PCI specific data */
             struct {
                    ...
             };
             };
      };

      We need to have anonymous union and a anonymous structure for the PCI
      fields, otherwise we would have to change all instances using these
      fields.

      For non PCI devices we will enforce a proper namespace and a non
      anonymous structure.

      Add helper function msi_desc_to_pci_sysdata() to retrieve sysdata from
      an MSI descriptor. To avoid pulling include/linux/pci.h into
      include/linux/msi.h, msi_desc_to_pci_sysdata() is implemented as a normal
      function instead of an inline function.

      irqchip: omap-intc: Improve IRQ handler

      As it turns out the current IRQ number will *always* be available from
      SIR register which renders the reads of PENDING registers as plain
      unnecessary overhead.

      In order to catch any situation where SIR reads as zero, we're adding
      a WARN() to turn it into a very verbose error and users actually
      report it.

      With this patch average running time of omap_intc_handle_irq() reduced
      from about 28.5us to 19.8us as measured by the kernel function
      profiler.

      Tested with BeagleBoneBlack Rev A5C.

      drm: gc now dead mode_group code

      Two nice things here:
      - drm_dev_register will truly register everything in the right order
        if the driver doesn't have a ->load callback. Before this we had to
        init the primary mode_group after the device nodes where already
        registered.

      - Less things to keep track of when reworking the connector locking,
        yay!

      drm: Stop filtering according to mode_group in getresources

      It's been dead code since forever since mode groups haven't ever been
      implemented. On top of that it's also been non-functional since we
      only ever filtered the getresources ioctl and not any of the others
      nor the mode object lookup code.

      Given overwhelming evidence it looks like this isn't a feature we
      need, hence remove it.

      drm: Roll out drm_for_each_connector more

      Now that we also grab the connection_mutex and so fixed the race with
      atomic modeset we can use the iterator there too.

      The other special case is drm_connector_unplug_all which would have a
      locking inversion with the sysfs store/show functions if we'd grab the
      mode_config.mutex around the unplug. We could just grab
      connection_mutex instead, but that's a bit too much a dirty trick for
      my taste. Also it's only used by udl, which doesn't do any other kind
      of connector hotplugging, so should be race-free. Hence just stick
      with a comment for now.

      drm: Amend connector list locking rules

      Now that dp mst hotplug takes all locks we can amend the locking rules
      for the iterators. This is needed before we can roll these out in the
      atomic code to avoid getting burried in WARNINGs.

      v2: Rebase onto the extracted list locking assert and add a comment to
      explain the rules.

      v3: Fixup German->English translation fail in the comment.

      drm/radeon: Take all modeset locks for DP MST hotplug

      Similar with the i915 take all modeset locks for mst hotplug. This is
      needed to make sure radeon holds both mode_config.mutex and
      mode_config.connection_mutex when updating the connector_list, which
      is the new (interim) locking regime we want for that.

      drm/i915: Take all modeset locks for DP MST hotplug

      While auditing various users of the connector/encoder lists I realized
      that the atomic code is a very prolific user of them. And it only ever
      grabs the mode_config->connection_mutex, but not the
      mode_config->mutex like all the other code walking encoder/connector
      lists.

      The problem is that we can't grab the mode_config.mutex late in atomic
      code since that would lead to locking inversions. And we don't want to
      grab it unconditionally like the legacy set_config modeset path since
      that would render all the fine-grained locking moot.

      Instead just grab more locks in the dp mst hotplug code. Note that
      drm_connector_init (which is the one adding the connector to these
      lists) already uses drm_modeset_lock_all.

      The other reason for grabbing all locks is that the dpms off in the
      unplug function amounts to a modeset, so better to take all required
      locks for that.

      drm: Check locking in drm_for_each_connector

      Because of DP MST connectors can now be hotplugged and we must hold
      the right lock when walking the connector lists.  Enforce this by
      checking the locking in our shiny new list walking macros.

      v2: Extract the locking check into a small static inline helper to
      help readability. This will be more important when we make the
      read list access rules more complicated in later patches. Inspired by
      comments from Chris. Unfortunately, due to header loops around the
      definition of struct drm_device the function interface is a bit funny.

      v3: Encoders aren't hotadded/removed. For each dp mst encoder we
      statically create one fake encoder per pipe so that we can support as
      many mst sinks as the hw can (Dave).

      drm/fbdev-helper: Grab mode_config.mutex in 
drm_fb_helper_single_add_all_connectors

      This is now truly only duct-tape to keep locking checks happy since
      calling this function when hpd or polling are already enabled is a
      bug. The fbdev helper can't cope with hotplug changes yet at this
      point, only after that.

      Otoh a bit more robustness in this function can't hurt, and with this
      fbdev can actually cope with hotplug changes. And it's also more
      consistent with the connector hotadd/remove dp mst needs to do.
      Therefore document this as new official behavior.

      drm/probe-helper: Grab mode_config.mutex in poll_init/enable

      So on first looks this seems superflous since drivers should ensure
      correct ordering to not make this a problem. Otoh ordering constraints
      between hdp, fbdev load and enabling polling are already tricky on
      some hardware and it helps to be more robust.

      But the real goal is to just shut up a locking WARN_ON I'd like to
      add, which means init code gets some additional locks just for
      uniformity.

      v2: Also grab the lock for the public poll_enable, not just poll_init
      which is used for resume, with the same justification.

      ARM: STi: Add code to release secondary cores from holding pen.

      Most upstream devs boot STi platform via JTAG which abuses the
      boot process by setting the PC of secondary cores directly. As
      a consquence, booting STi platforms via u-boot results in only
      the primary core being brought up as the code to manage the
      holding pen is not upstream.

      This patch adds the necessary code to bring the secondary cores
      out of the holding pen. It uses the cpu-release-addr DT property
      to get the address of the holding pen from the bootloader.

      s390/cio: Implement proper Link Incident Record handling

      A hardware problem on a FICON link is reported by the Channel Subsystem
      to the operating system via a Link Incident Record (LIR). In response,
      the operating system should issue a message that enables hardware
      service personnel to identify and repair the failing component.

      Current Linux LIR handling is broken because LIR data is incorrectly
      interpreted and no log message is generated.

      This patch fixes Linux LIR handling by implementing a new log message
      for LIRs indicating a degraded or non-operational link. Also LIRs are
      no longer used to deactivate channel paths because the available data
      does not reliably allow to determine the affected channel path.

      s390/kvm: integrate HANDLE_SIE_INTERCEPT into cleanup_critical

      Currently there are two mechanisms to deal with cleanup work due to
      interrupts. The HANDLE_SIE_INTERCEPT macro is used to undo the changes
      required to enter SIE in sie64a. If the SIE instruction causes a program
      check, or an asynchronous interrupt is received the HANDLE_SIE_INTERCEPT
      code forwards the program execution to sie_exit.

      All the other critical sections in entry.S are handled by the code in
      cleanup_critical that is called by the SWITCH_ASYNC macro.

      Move the sie64a function to the beginning of the critical section and
      add the code from HANDLE_SIE_INTERCEPT to cleanup_critical. Add a special
      case for the sie64a cleanup to the program check handler.

      s390/kvm: fix interrupt race with HANDLE_SIE_INTERCEPT

      The HANDLE_SIE_INTERCEPT macro is used in the interrupt handlers
      and the program check handler to undo a few changes done by sie64a.
      Among them are guest vs host LPP, the gmap ASCE vs kernel ASCE and
      the bit that indicates that SIE is currently running on the CPU.

      There is a race of a voluntary SIE exit vs asynchronous interrupts.
      If the CPU completed the SIE instruction and the TM instruction of
      the LPP macro at the time it receives an interrupt, the interrupt
      handler will run while the LPP, the ASCE and the SIE bit are still
      set up for guest execution. This might result in wrong sampling data,
      but it will not cause data corruption or lockups.

      The critical section in sie64a needs to be enlarged to include all
      instructions that undo the changes required for guest execution.

      s390/kernel: lazy restore fpu registers

      Improve the save and restore behavior of FPU register contents to use the
      vector extension within the kernel.

      The kernel does not use floating-point or vector registers and, therefore,
      saving and restoring the FPU register contents are performed for handling
      signals or switching processes only.  To prepare for using vector
      instructions and vector registers within the kernel, enhance the save
      behavior and implement a lazy restore at return to user space from a
      system call or interrupt.

      To implement the lazy restore, the save_fpu_regs() sets a CPU information
      flag, CIF_FPU, to indicate that the FPU registers must be restored.
      Saving and setting CIF_FPU is performed in an atomic fashion to be
      interrupt-safe.  When the kernel wants to use the vector extension or
      wants to change the FPU register state for a task during signal handling,
      the save_fpu_regs() must be called first.  The CIF_FPU flag is also set at
      process switch.  At return to user space, the FPU state is restored.  In
      particular, the FPU state includes the floating-point or vector register
      contents, as well as, vector-enablement and floating-point control.  The
      FPU state restore and clearing CIF_FPU is also performed in an atomic
      fashion.

      For KVM, the restore of the FPU register state is performed when restoring
      the general-purpose guest registers before the SIE instructions is 
started.
      Because the path towards the SIE instruction is interruptible, the CIF_FPU
      flag must be checked again right before going into SIE.  If set, the guest
      registers must be reloaded again by re-entering the outer SIE loop.  This
      is the same behavior as if the SIE critical section is interrupted.

      s390/kvm: validate the floating-point control before restoring it

      The kvm_arch_vcpu_load() does not validate whether the floating-point
      control (FPC) is valid.  Further, the return code of the restore is not
      checked too.  If the FPC is invalid, the restore fails and the host FPC
      value might remain.  The correct behavior would be to clear the FPC if it
      is not valid.  Hence, validate the FPC value and, optionally, reset the
      value before restoring it.

      ARM: zynq: Set bit 22 in PL310 AuxCtrl register (6395/1)

      This patch is based on the
      commit 1a8e41cd672f ("ARM: 6395/1: VExpress: Set bit 22 in the PL310
      (cache controller) AuxCtlr register")

      Clearing bit 22 in the PL310 Auxiliary Control register (shared
      attribute override enable) has the side effect of transforming Normal
      Shared Non-cacheable reads into Cacheable no-allocate reads.

      Coherent DMA buffers in Linux always have a cacheable alias via the
      kernel linear mapping and the processor can speculatively load cache
      lines into the PL310 controller. With bit 22 cleared, Non-cacheable
      reads would unexpectedly hit such cache lines leading to buffer
      corruption.

      For Zynq, this fix avoids memory inconsistencies between Gigabit
      Ethernet controller (GEM) and CPU when DMA_CMA is disabled.

      x86/build: Fix detection of GCC -mpreferred-stack-boundary support

      As per:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53383

      GCC only allows -mpreferred-stack-boundary=3 on x86_64 if -mno-sse is set.
      That means that cc-option will not detect -mpreferred-stack-boundary=3
      support, because we test for it before setting -mno-sse.

      Fix it by reordering the Makefile bits.

      Compile-tested only.  This should help avoid code generation
      issues such as the one that was worked around in:

        b96fecbfa8c8 ("x86/fpu: Fix boot crash in the early FPU code")

      I'm a bit concerned that we could still have problems on older
      GCC versions given that our asm code does not respect GCC's idea
      of the ABI-required stack alignment.

      ====================
      sfc: support for cascaded multicast filtering

      Recent versions of firmware for SFC9100 adapters add support for filter
       chaining, in which packets matching multiple filters are delivered to all
       filters' recipients, rather than only the highest match-priority filter 
as was
       previously the case.
      This patch series enables this feature and redesigns the filter handling 
code
       to make use of it; in particular, subscribing to a multicast address on 
one
       function no longer prevents traffic to that address reaching another 
function
       which is in promiscuous or allmulti mode.
      If the firmware does not support filter chaining, the driver will fall 
back to
       the old behaviour.

      sfc: support cascaded multicast filters

      If the workaround to support cascaded multicast filters 
("workaround_26807") is
      enabled, the broadcast filter and individual multicast filters are not 
inserted
      when in promiscuous or allmulti mode.

      There is a race while inserting and removing filters when entering and 
leaving
      promiscuous mode.  When changing promiscuous state with cascaded multicast
      filters, the old multicast filters are removed before inserting the new 
filters
      to avoid duplicating packets; this can lead to dropped packets until all
      filters have been inserted.

      The efx_nic:mc_promisc flag is added to record the presence of a multicast
      promiscuous filter; this gives a simple way to tell if the promiscuous 
state is
      changing.

      If a function is in promiscuous mode and another function has a broadcast

       multicast filter inserted, the function in promiscuous mode won't see 
that
       broadcast or multicast traffic.
      Most notably this breaks broadcast, which means ARP doesn't work. Less
       show-stoppingly, a function listening on a multicast address that's also 
in
       promiscuous mode will not see that multicast traffic if another function 
is
       also listening on that multicast address.

      sfc: warn if other functions have been reset by MCFW

      When enabling the workaround for cascaded multicast filters, the MC
       can reset other functions if they have already inserted filters.
       In that case, the workaround has been enabled, but print an info
       message in the log recording that other functions had to be reset.

      As other functions were reset, the MC will have incremented its boot
       count, so also increment the warm_boot_count on the function which
       enabled the workaround, as that function won't have received an MC
       reboot event and does not need to reset.

      sfc: enable cascaded multicast filters in MCFW

      After creating event queue 0, check to see if the workaround is enabled,
       and enable it if necessary.  This will be called during PCI probe and
       also when coming back up after a reset.  The nic_data->workaround_26807
       will be used in the future to control the filter insertion behaviour
       based on this workaround.

      Only the primary PF can enable this workaround, so tolerate an EPERM
       error and continue.  Otherwise, if any step in the checking and enabling
       of the workaround fails, the event queue must be removed.

      We check that workaround is implemented before trying to enable it,
       and store the current workaround setting before trying to change it.

      ext4: implement cgroup writeback support

      For ordered and writeback data modes, all data IOs go through
      ext4_io_submit.  This patch adds cgroup writeback support by invoking
      wbc_init_bio() from io_submit_init_bio() and wbc_account_io() in
      io_submit_add_bh().  Journal data which is written by jbd2 worker is
      left alone by this patch and will always be written out from the root
      cgroup.

      ext4_fill_super() is updated to set MS_CGROUPWB when data mode is
      either ordered or writeback.  In journaled data mode, most IOs become
      synchronous through the journal and enabling cgroup writeback support
      doesn't make much sense or difference.  Journaled data mode is left
      alone.

      Lightly tested with sequential data write workload.  Behaves as
      expected.

      ext4_io_submit_init() takes the pointer to writeback_control to test
      its sync_mode and determine between WRITE and WRITE_SYNC and records
      the result in ->io_op.  This patch makes it record the pointer
      directly and moves the test to ext4_io_submit().

      This doesn't cause any noticeable differences now but having
      writeback_control available throughout IO submission path will be
      depended upon by the planned cgroup writeback support.

      ARM: shmobile: lager: Fix adv7511 IRQ sensing

      The adv7511 IRQ is low level triggered, not falling edge triggered. The
      wrong sense configuration results in no interrupt being triggered at
      all, breaking hotplug detection. Fix it.

      tipc: fix compatibility bug

      In commit d999297c3dbbe7fdd832f7fa4ec84301e170b3e6
      ("tipc: reduce locking scope during packet reception") we introduced
      a new function tipc_link_proto_rcv(). This function contains a bug,
      so that it sometimes by error sends out a non-zero link priority value
      in created protocol messages.

      The bug may lead to an extra link reset at initial link establising
      with older nodes. This will never happen more than once, whereafter
      the link will work as intended.

      We fix this bug in this commit.

      Changes in v5:

      - reworded the commit message for patch 2 to make it clear what it fixes 
and

      Initial cover letter from Stas:

      Hello.

      Currently the link status auto-negotiation is enabled
      for any SGMII link with fixed-link DT binding.
      The regression was reported:
      https://lkml.org/lkml/2015/7/8/865
      Apparently not all HW that implements SGMII protocol, generates the
      inband status for the auto-negotiation to work.
      More details here:
      https://lkml.org/lkml/2015/7/10/206

      The following patches reverts to the old behavior by default,
      which is to not enable the auto-negotiation for fixed-link.
      The new DT property is added that allows to explicitly request
      the auto-negotiation.

      mvneta: use inband status only when explicitly enabled

      The commit 898b2970e2c9 ("mvneta: implement SGMII-based in-band link state
      signaling") implemented the link parameters auto-negotiation 
unconditionally.
      Unfortunately it appears that some HW that implements SGMII protocol,
      doesn't generate the inband status, so it is not possible to 
auto-negotiate
      anything with such HW.

      This patch enables the auto-negotiation only if explicitly requested with
      the 'managed' DT property.

      This patch fixes the following regression:

      of_mdio: add new DT property 'managed' to specify the PHY management type

      Currently the PHY management type is selected by the MAC driver arbitrary.
      The decision is based on the presence of the "fixed-link" node and on a
      will of the driver's authors.
      This caused a regression recently, when mvneta driver suddenly started
      to use the in-band status for auto-negotiation on fixed links.
      It appears the auto-negotiation may not work when expected by the MAC 
driver.
      Sebastien Rannou explains:
      << Yes, I confirm that my HW does not generate an in-band status. AFAIK, 
it's
      a PHY that aggregates 4xSGMIIs to 1xQSGMII ; the MAC side of the PHY (with
      inband status) is connected to the switch through QSGMII, and in this 
context
      we are on the media side of the PHY. >>
      https://lkml.org/lkml/2015/7/10/206

      This patch introduces the new string property 'managed' that allows
      the user to set the management type explicitly.
      The supported values are:
      "auto" - default. Uses either MDIO or nothing, depending on the presence
      of the fixed-link node
      "in-band-status" - use in-band status

      net: phy: fixed_phy: handle link-down case

      fixed_phy_register() currently hardcodes the fixed PHY link to 1, and
      expects to find a "speed" parameter to provide correct information
      towards the fixed PHY consumer.

      In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band
      status auto-negotiation) fixed PHYs, none of these parameters can be
      provided since they will be auto-negotiated, hence, we just provide a
      zero-initialized fixed_phy_status to fixed_phy_register() which makes it
      fail when we call fixed_phy_update_regs() since status.speed = 0 which
      makes us hit the "default" label and error out.

      Without this change, we would also see potentially inconsistent
      speed/duplex parameters for fixed PHYs when the link is DOWN.

      net: dsa: bcm_sf2: Do not override speed settings

      The SF2 driver currently overrides speed settings for its port
      configured using a fixed PHY, this is both unnecessary and incorrect,
      because we keep feedback to the hardware parameters that we read from
      the PHY device, which in the case of a fixed PHY cannot possibly change
      speed.

      This is a required change to allow the fixed PHY code to allow
      registering a PHY with a link configured as DOWN by default and avoid
      some sort of circular dependency where we require the link_update
      callback to run to program the hardware, and we then utilize the fixed
      PHY parameters to program the hardware with the same settings.

      PCI: Add dev_flags bit to access VPD through function 0

      Add a dev_flags bit, PCI_DEV_FLAGS_VPD_REF_F0, to access VPD through
      function 0 to provide VPD access on other functions.  This is for hardware
      devices that provide copies of the same VPD capability registers in
      multiple functions.  Because the kernel expects that each function has its
      own registers, both the locking and the state tracking are affected by VPD
      accesses to different functions.

      On such devices for example, if a VPD write is performed on function 0,
      *any* later attempt to read VPD from any other function of that device 
will
      hang.  This has to do with how the kernel tracks the expected value of the
      F bit per function.

      Concurrent accesses to different functions of the same device can not only
      hang but also corrupt both read and write VPD data.

      When hangs occur, typically the error message:

        vpd r/w failed.  This is likely a firmware bug on this device.

      will be seen.

      Never set this bit on function 0 or there will be an infinite recursion.

      ====================
      Lightweight & flow based encapsulation

      This series combines the work previously posted by Roopa, Robert and
      myself. It's according to what we discussed at NFWS. The motivation
      of this series is to:

       * Consolidate code between OVS and the rest of the kernel and get
         rid of OVS vports and instead represent them as pure net_devices.
       * Introduce a lightweight tunneling mechanism which enables flow
         based encapsulation to improve scalability on both RX and TX.
       * Do the above in an encapsulation unspecific way so that the
         encapsulation type is eventually abstracted away from the user.
       * Use the same forwarding decision for both native forwarding and
         encapsulation thus allowing to switch between native IPv6 and
         UDP encapsulation based on endpoint without requiring additional
         logic

      The fundamental changes introduces in this series are:
       * A new RTA_ENCAP Netlink attribute for routes carrying encapsulation
         instructions. Depending on the specified type, the instructions
         apply to UDP encapsulations, MPLS and possible other in the future.
       * Depending on the encapsulation type, the output function of the
         dst is directly overwritten or the dst merely attaches metadata and
         relies on a subsequent net_device to apply it to the packet. The
         latter is typically used if an inner and outer IP header exist which
         require two subsequent routing lookups to be performed.
       * A new metadata_dst structure which can be attached to skbs to
         carry metadata in between subsystems. This new metadata transport
         is used to provide a single interface for VXLAN, routing and OVS
         to communicate through metadata.

      The OVS interfaces remain as-is but will transparently create a real
      VXLAN net_device in the background. iproute2 is extended with a new
      use cases:

        VXLAN:
        ip route add 40.1.1.1/32 encap vxlan id 10 dst 50.1.1.2 dev vxlan0

        MPLS:
        ip route add 10.1.1.0/30 encap mpls 200 via inet 10.1.1.1 dev swp1

      Performance implications:
        The additional memory allocation in the receive path should have
        performance implications although it is not observable in standard
        throughput tests if GRO is properly done. The correct net_device
        model outweights the additional cost of the allocation. Furthermore,
        this implication can be relaxed by reintroducing a direct unqueued
        path from a software device to a consumer like bridge or OVS if
        needed.

      vxlan: Flow based tunneling

      Allows putting a VXLAN device into a new flow-based mode in which
      skbs with a ip_tunnel_info dst metadata attached will be encapsulated
      according to the instructions stored in there with the VXLAN device
      defaults taken into consideration.

      Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is
      set, the packet processing will populate a ip_tunnel_info struct for
      each packet received and attach it to the skb using the new metadata
      dst.  The metadata structure will contain the outer header and tunnel
      header fields which have been stripped off. Layers further up in the
      stack such as routing, tc or netfitler can later match on these fields
      and perform forwarding. It is the responsibility of upper layers to
      ensure that the flag is set if the metadata is needed. The flag limits
      the additional cost of metadata collecting based on demand.

      This prepares the VXLAN device to be steered by the routing and other
      subsystems which allows to support encapsulation for a large number
      of tunnel endpoints and tunnel ids through a single net_device which
      improves the scalability.

      It also allows for OVS to leverage this mode which in turn allows for
      the removal of the OVS specific VXLAN code.

      Because the skb is currently scrubed in vxlan_rcv(), the attachment of
      the new dst metadata is postponed until after scrubing which requires
      the temporary addition of a new member to vxlan_metadata. This member
      is removed again in a later commit after the indirect VXLAN receive API
      has been removed.

      dst: Metadata destinations

      Introduces a new dst_metadata which enables to carry per packet metadata
      between forwarding and processing elements via the skb->dst pointer.

      The structure is set up to be a union. Thus, each separate type of
      metadata requires its own dst instance. If demand arises to carry
      multiple types of metadata concurrently, metadata dst entries can be
      made stackable.

      The metadata dst entry is refcnt'ed as expected for now but a non
      reference counted use is possible if the reference is forced before
      queueing the skb.

      In order to allow allocating dsts with variable length, the existing
      dst_alloc() is split into a dst_alloc() and dst_init() function. The
      existing dst_init() function to initialize the subsystem is being
      renamed to dst_subsys_init() to make it clear what is what.

      The check before ip_route_input() is changed to ignore metadata dsts
      and drop the dst inside the routing function thus allowing to interpret
      metadata in a later commit.

      ASoC: dapm: Avoid duplicating immutable strings

      When creating a new widget from a template the name string of the template
      is duplicated for the newly created widget. This is necessary because in
      some cases the string might be stored on the stack or other volatile
      memory locations.

      But most of the time the string is static const data, which means it is
      possible to use it directly without having to worry that it might get 
freed
      or changed.

      Use kstrdup_const() to handle duplicating the string. This function is
      capable of detecting whether a string is immutable and if it is returns 
the
      input without duplicating it. This will slightly reduce the runtime memory
      footprint of DAPM and also speed up initialization.

      mtd: m25p80: allow arbitrary OF matching for "jedec,spi-nor"

      When we added the "jedec,spi-nor" compatible string for use in this
      driver, we added it as a modalias option. The modalias can be derived in
      different ways for platform devices vs. device tree (of_*) matching. But
      for device tree matching (the primary target of this identifier string),
      the modalias is determined from the first entry in the 'compatible'
      property. IOW, the following properties would bind to this driver:

        // Option (a), modalias = "spi-nor"
        compatible = "jedec,spi-nor";

        // Option (b), modalias = "spi-nor"
        compatible = "idontknowwhatimdoing,spi-nor";

      But the following would not:

        // Option (c), modalias = "shinynewdevice"
        compatible = "myvendor,shinynewdevice", "jedec,spi-nor";

      So, we'd like to match (a) and (c) (even when we don't have an explicit
      entry for "shinynewdevice"), and we'd rather not allow (b).

      To do this, we
        (1) always (for devices without specific platform data) pass the
            modalias to the spi-nor library;
        (2) rework the spi-nor library to not reject "bad" names, and
            instead just fall back to autodetection; and
        (3) add the .of_match_table to properly catch all "jedec,spi-nor".

      This allows (a) and (c) without warnings, and rejects (b).

      regulator: rk808: make better use of the gpiod API

      The gpiod functions include variants for managed gpiod resources. Use it
      to simplify the remove function.

      As the driver handles a device node without a specification of dvs gpios
      just fine, additionally use the variant of gpiod_get exactly for this
      use case. This makes error checking more strict.

      As a third benefit this patch makes the driver use the flags parameter
      of gpiod_get* which will not be optional any more after 4.2 and so
      prevents a build failure when the respective gpiod commit is merged.

      arm64: dts: Add APM X-Gene PCIe 64-bit prefetchable window

      Add a large window (up to 64GB) for X-Gene PCIe nodes to support devices
      that require huge BARs.

      Each X-Gene PCIe node will now have two memory windows: a 32-bit
      non-prefetchable window and a 64-bit prefetchable window.

      PCI: Restore ACS configuration as part of pci_restore_state()

      Previously we did not restore ACS state after a PCIe reset.  This meant
      that we could not reassign interfaces after a system suspend because the
      D0->D3 transition disabled ACS, and we didn't restore it when going back 
to
      D0.

      Restore ACS configuration in pci_restore_state().

      NVMe: Use CMB for the IO SQes if available

      Some controllers have a controller-side memory buffer available for use
      for submissions, completions, lists, or data.

      If a CMB is available, the entire CMB will be ioremapped and it will
      attempt to map the IO SQes onto the CMB. The queues will be shrunk as
      needed. The CMB will not be used if the queue depth is shrunk below some
      threshold where it may have reduced performance over a larger queue
      in system memory.

      PCI: xilinx: Check for MSI interrupt flag before handling as INTx

      Occasionally both MSI and INTx bits in the interrupt decode register are
      set at once by the Xilinx AXI PCIe Bridge, so the MSI flag in the 
interrupt
      message should be checked to ensure that the correct handler is used.

      If this check is not in place and the interrupt message type is MSI, the
      INTx handler will be used erroneously when both type bits are set.  This
      will also be followed by a second read of the message FIFO, which can
      result in the function returning early and the interrupt decode register
      not being cleared if the FIFO is now empty.

      iwlegacy: convert hex_dump_to_buffer() to %*ph

      There is no need to use hex_dump_to_buffer() in the cases like this:

        hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);      /* len 
<= 16 */
        sprintf("%s\n", outbuf);

      since it maybe easily converted to simple:

        sprintf("%*ph\n", len, buf);

      Note: it seems in the case the output is groupped by 2 bytes and looks 
like a
      typo. Thus, patch changes that to plain byte stream.

      brcmfmac: set wiphy's addresses to provide valid MACs

      Broadcom's firmware requires every BSS to use MAC address with unique
      last few bits. The amount of bits may depend on a particular firmware,
      it was verified to be 2 for BCM43602 one.
      If this condition won't be fulfilled firmware will reject such MAC:
      brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52

      We don't want to simply set addr_mask as it would also disallow using
      locally administrated bit. Instead let's build a list of addresses
      manually enabling 0x2 bit for extra interfaces.

       ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &=

      There's no way for frame ftype/stype to be
      mistreated as the offending 'moredata' flag when
      considering cab queue.

      This could've however theoretically led sometimes
      to increased power consumption on connected
      stations as they would keep their Rx active
      waiting for frames that would never come.

      ath9k: make DMA stop related messages debug-only

      A long time ago, ath9k had issues during reset where the DMA engine
      would stay active and could potentially corrupt memory.
      To debug those issues, the driver would print warnings whenever they
      occur.

      Nowadays, these issues are gone and the primary cause of these messages
      is if the MAC is stuck during reset or busy processing a long
      transmission. This is fairly harmless, yet these messages continue to
      worry users.

      To reduce the number of bogus bug reports, turn these messages into
      debug messages and count their occurence in the "reset" debugfs file.

      mwifiex: usb: Fix double add error when submitting rx urb

      There is an error that can occur where the driver adds the same URB to 
USB submission list twice.
      This happens since mwifiex_usb_submit_rem_rx can submit packets at same 
time as an rx urb complete callback.
      This causes list corruption and is fixed by not setting the skb to NULL 
when submitting an rx packet.

      drm/i915: remove unnecessary null test

      While creating the debugfs file we are setting the inode->i_private to
      dev. That same dev is passed to these functions as private of struct
      seq_file via single_open(). Moreover single_open is setting
      file->private_data->private to dev.
      So at this point it can never be NULL.

      mwifiex: avoid freeing improper pointer in mwifiex_set_wowlan_mef_entry

      mwifiex_set_wowlan_mef_entry attempts to free a passed-in pointer in
      case of an error.  The only caller (mwifiex_set_mef_filter) passes that
      pointer as an offset into allocated memory, so any attempt to free that
      will not be the actual allocated pointer.

      Address this by changing mwifiex_set_wowlan_mef_entry to not do any
      free, and to cause mwifiex_set_mef_filter to do the appropriate free if
      the call to mwifiex_set_wowlan_mef_entry fails.

      KVM: arm64: guest debug, HW assisted debug support

      This adds support for userspace to control the HW debug registers for
      guest debug. In the debug ioctl we copy an IMPDEF registers into a new
      register set called host_debug_state.

      We use the recently introduced vcpu parameter debug_ptr to select which
      register set is copied into the real registers when world switch occurs.

      I've made some helper functions from hw_breakpoint.c more widely
      available for re-use.

      As with single step we need to tweak the guest registers to enable the
      exceptions so we need to save and restore those bits.

      Two new capabilities have been added to the KVM_EXTENSION ioctl to allow
      userspace to query the number of hardware break and watch points
      available on the host hardware.

      KVM: arm64: introduce vcpu->arch.debug_ptr

      This introduces a level of indirection for the debug registers. Instead
      of using the sys_regs[] directly we store registers in a structure in
      the vcpu. The new kvm_arm_reset_debug_ptr() sets the debug ptr to the
      guest context.

      Because we no longer give the sys_regs offset for the sys_reg_desc->reg
      field, but instead the index into a debug-specific struct we need to
      add a number of additional trap functions for each register. Also as the
      generic generic user-space access code no longer works we have
      introduced a new pair of function pointers to the sys_reg_desc structure
      to override the generic code when needed.

      KVM: arm64: re-factor hyp.S debug register code

      This is a pre-cursor to sharing the code with the guest debug support.
      This replaces the big macro that fishes data out of a fixed location
      with a more general helper macro to restore a set of debug registers. It
      uses macro substitution so it can be re-used for debug control and value
      registers. It does however rely on the debug registers being 64 bit
      aligned (as they happen to be in the hyp ABI).

      KVM: arm64: guest debug, add support for single-step

      This adds support for single-stepping the guest. To do this we need to
      manipulate the guests PSTATE.SS and MDSCR_EL1.SS bits to trigger
      stepping. We take care to preserve MDSCR_EL1 and trap access to it to
      ensure we don't affect the apparent state of the guest.

      As we have to enable trapping of all software debug exceptions we
      suppress the ability of the guest to single-step itself. If we didn't we
      would have to deal with the exception arriving while the guest was in
      kernelspace when the guest is expecting to single-step userspace. This
      is something we don't want to unwind in the kernel. Once the host is no
      longer debugging the guest its ability to single-step userspace is
      restored.

      KVM: arm64: guest debug, add SW break point support

      This adds support for SW breakpoints inserted by userspace.

      We do this by trapping all guest software debug exceptions to the
      hypervisor (MDCR_EL2.TDE). The exit handler sets an exit reason of
      KVM_EXIT_DEBUG with the kvm_debug_exit_arch structure holding the
      exception syndrome information.

      It will be up to userspace to extract the PC (via GET_ONE_REG) and
      determine if the debug event was for a breakpoint it inserted. If not
      userspace will need to re-inject the correct exception restart the
      hypervisor to deliver the debug exception to the guest.

      Any other guest software debug exception (e.g. single step or HW
      assisted breakpoints) will cause an error and the VM to be killed. This
      is addressed by later patches which add support for the other debug
      types.

      KVM: arm: introduce kvm_arm_init/setup/clear_debug

      This is a precursor for later patches which will need to do more to
      setup debug state before entering the hyp.S switch code. The existing
      functionality for setting mdcr_el2 has been moved out of hyp.S and now
      uses the value kept in vcpu->arch.mdcr_el2.

      As the assembler used to previously mask and preserve MDCR_EL2.HPMN I've
      had to add a mechanism to save the value of mdcr_el2 as a per-cpu
      variable during the initialisation code. The kernel never sets this
      number so we are assuming the bootcode has set up the correct value
      here.

      This also moves the conditional setting of the TDA bit from the hyp code
      into the C code which is currently used for the lazy debug register
      context switch code.

      x86/boot: Obsolete the MCA sys_desc_table

      The kernel does not support the MCA bus anymroe, so mark sys_desc_table
      as obsolete: remove any reference from the code together with the 
remaining
      of MCA logic.

      x86/selftests, x86/vm86: Improve entry_from_vm86 selftest

      The entry_from_vm86 selftest was very weak.  Improve it: test
      more types of kernel entries from vm86 mode and test them more
      carefully.

      While we're at it, try to improve behavior on non-SEP CPUs.  The
      old code was buggy because I misunderstood the intended
      semantics of #UD in vm86, so I didn't handle a possible signal.

      drivers/video/fbdev/atyfb: Use arch_phys_wc_add() and ioremap_wc()

      This driver uses strong UC for the MMIO region, and ioremap_wc()
      for the framebuffer to whitelist for the WC MTRR that can be
      changed to WC. On PAT systems we don't need the MTRR call so
      just use arch_phys_wc_add() there, this lets us remove all those
      ifdefs. Let's also be consistent and use ioremap_wc() for ATARI
      as well.

      There are a few motivations for this:

        a) Take advantage of PAT when available.

        b) Help bury MTRR code away, MTRR is architecture specific and
           on x86 it is being replaced by PAT.

        c) Help with the goal of eventually using _PAGE_CACHE_UC over
           _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
           de33c442e titled "x86 PAT: fix performance drop for glx,
           use UC minus for ioremap(), ioremap_nocache() and
           pci_mmap_page_range()").

      The conversion done is expressed by the following Coccinelle
      SmPL patch, it additionally required manual intervention to
      address all the ifdeffery and removal of redundant things which
      arch_phys_wc_add() already addresses such as verbose message
      about when MTRR fails and doing nothing when we didn't get an

      drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC

      Replace a WC MTRR call followed by a UC MTRR "hole" call with a
      single WC MTRR call and use strong UC to protect the MMIO region
      and account for the device's architecture and MTRR size
      requirements.

      The atyfb driver relies on two overlapping MTRRs. It does this
      to account for the fact that, on some devices, it has the MMIO
      region bundled together with the framebuffer on the same PCI BAR
      and the hardware requirement on MTRRs on both base and size to
      be powers of two.

      In the worst case, the PCI BAR is of 16 MiB while the MMIO
      region is on the last 4 KiB of the same PCI BAR. If we use just
      one MTRR for WC, we can only end up with an 8 MiB or 16 MiB
      framebuffer. Using a 16 MiB WC framebuffer area is unacceptable
      since we need the MMIO region to not be write-combined. An 8 MiB
      WC framebuffer option does not let use quite a bit of
      framebuffer space, it would reduce the resolution capability of
      the device considerably.

      An alternative is to use many MTRRs but on some systems that
      could mean not having enough MTRRs to cover the framebuffer. The
      current solution is to issue a 16 MiB WC MTRR followed by a 4
      KiB UC MTRR on the last 4 KiB. Its worth mentioning and
      documenting that the current ioremap*() strategy as well: the
      first ioremap() is used only for the MMIO region, a second
      ioremap() call is used for the framebuffer *and* the MMIO
      region, the MMIO region then ends up mmapped twice.

      Two ioremap() calls are used since in some situations the
      framebuffer actually ends up on a separate auxiliary PCI BAR,
      but this is not always true. In the worst case, the PCI BAR is
      shared for both MMIO and the framebuffer. By allowing
      overlapping ioremap() calls, the driver enables two types of
      devices with one simple ioremap() strategy.

      See also:

        2f9e897353fc ("x86/mm/mtrr, pat: Document Write Combining MTRR type 
effects on PAT / non-PAT pages")

      By default, Linux today defaults both pci_mmap_page_range() and
      ioremap_nocache() to use _PAGE_CACHE_MODE_UC_MINUS. On x86,
      ioremap() aliases ioremap_nocache(). The preferred value for
      Linux may soon change, however, the goal is to use
      _PAGE_CACHE_MODE_UC by default in the future.

      We can use ioremap_uc() to set PCD=1, PWT=1 on non-PAT systems
      and use a PAT value of UC for PAT systems. This will ensure the
      same settings are in place regardless of what Linux decides to
      use by default later and to not regress our MTRR strategy since
      the effective memory type will differ depending on the value
      used. Using a WC MTRR on such an area will be nullified. This
      technique can be used to protect the MMIO region in this
      driver's case and address the restrictions of the device's
      architecture as well as restrictions set upon us by powers of 2
      when using MTRRs.

      This allows us to replace the two MTRR calls with a single 16
      MiB WC MTRR and use page-attribute settings for non-PAT and PAT
      entry values for PAT systems to ensure the appropriate effective
      memory type won't have a write-combining effect on the MMIO
      region on both non-PAT and PAT systems. The framebuffer area
      will be sure to get the write-combined effective memory type by
      white-listing it with ioremap_wc().

      We ensure the desired effective memory types are set by:

      0) Using one ioremap_uc() for the MMIO region alone.
         This will set the page attribute settings for the MMIO
         region to PCD=1, PWT=1 for non-PAT systems while using a
         strong UC value on PAT systems.

      1) Fixing the framebuffer ioremapped area to exclude the
         MMIO region and using ioremap_wc() instead to whitelist
         the area we want for write-combining.

      In both cases, an implementation defined (as per 2f9e897353fc)
      effective memory type of WC is used for the framebuffer for
      non-PAT systems.

      drivers/video/fbdev/atyfb: Clarify ioremap() base and length used

      Adjust the ioremap() call for the framebuffer to use the same
      values we later use for the framebuffer. This will make it
      easier to review the next change.

      The size of the framebuffer varies but since this is for PCI we
      *know* this defaults to 0x800000. atyfb_setup_generic() is
      *only* used on PCI probe.

      No functional change.

      x86/mm, asm-generic: Add IOMMU ioremap_uc() variant default

      We currently have no safe way of currently defining architecture
      agnostic IOMMU ioremap_*() variants. The trend is for folks to
      *assume* that ioremap_nocache() should be the default everywhere
      and then add this mapping on each architectures -- this is not
      correct today for a variety of reasons.

      We have two options:

        1) Sit and wait for every architecture in Linux to get a
           an ioremap_*() variant defined before including it upstream.

        2) Gather consensus on a safe architecture agnostic ioremap_*()
           default.

      Approach 1) introduces development latencies, and since 2) will
      take time and work on clarifying semantics the only remaining
      sensible thing to do to avoid issues is returning NULL on
      ioremap_*() variants.

      In order for this to work we must have all architectures declare
      their own ioremap_*() variants as defined. This will take some
      work, do this for ioremp_uc() to set the example as its only
      currently implemented on x86. Document all this.

      We only provide implementation support for ioremap_uc() as the
      other ioremap_*() variants are well defined all over the kernel
      for other architectures already.

      x86/kconfig/32: Rename CONFIG_VM86 and default it to 'n'

      VM86 is entirely broken if ptrace, syscall auditing, or
      NOHZ_FULL is in use.  The code is a big undocumented mess, it's
      a real PITA to test, and it looks like a big chunk of vm86_32.c
      is dead code.  It also plays awful games with the entry asm.

      No one should be using it anyway. Use DOSBOX or KVM instead.

      Let's accelerate its slow death.  Remove it from EXPERT and
      default it to n.  Distros should not enable it.  In the unlikely
      event that some user needs it, they can easily re-enable it.

      While we're at it, rename it to CONFIG_X86_LEGACY_VM86 so that 'make
      oldconfig' users will be prompted again.  I left CONFIG_VM86 as
      an alias to avoid a treewide replacement of the names.  We can
      clean that up once the current asm and vm86 code churn settles
      down.

      locking/spinlocks: Force inlining of spinlock ops

      With both gcc 4.7.2 and 4.9.2, sometimes GCC mysteriously
      doesn't inline very small functions we expect to be inlined.
      See:

          https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66122

      In particular, with this config:

         http://busybox.net/~vda/kernel_config

      there are more than a thousand copies of tiny spinlock-related
      functions:

        $ nm --size-sort vmlinux | grep -iF ' t ' | uniq -c | grep -v '^ *1 ' | 
sort -rn | grep ' spin'
          473 000000000000000b t spin_unlock_irqrestore
          292 000000000000000b t spin_unlock
          215 000000000000000b t spin_lock
          134 000000000000000b t spin_unlock_irq
          130 000000000000000b t spin_unlock_bh
          120 000000000000000b t spin_lock_irq
          106 000000000000000b t spin_lock_bh

      Disassembly:

       ffffffff81004720 <spin_lock>:
       ffffffff81004720:       55                      push   %rbp
       ffffffff81004721:       48 89 e5                mov    %rsp,%rbp
       ffffffff81004724:       e8 f8 4e e2 02          callq <_raw_spin_lock>
       ffffffff81004729:       5d                      pop    %rbp
       ffffffff8100472a:       c3                      retq

      This patch fixes this via s/inline/__always_inline/ in
      spinlock.h. This decreases vmlinux by about 40k:

      x86/entry/syscalls: Wire up 32-bit direct socket calls

      On x86_64, there's no socketcall syscall; instead all of the
      socket calls are real syscalls.  For 32-bit programs, we're
      stuck offering the socketcall syscall, but it would be nice to
      expose the direct calls as well.  This will enable seccomp to
      filter socket calls (for new userspace only, but that's fine for
      some applications) and it will provide a tiny performance boost.

      drm/i915: Add provision to extend Golden context batch

      The Golden batch carries 3D state at the beginning so that HW starts with
      a known state. It is carried as a binary blob which is auto-generated from
      source. The idea was it would be easier to maintain and keep the 
complexity
      out of the kernel which makes sense as we don't really touch it. However 
if
      you really need to update it then you need to update generator source and
      keep the binary blob in sync with it.

      There is a need to patch this in bxt to send one additional command to 
enable
      a feature. A solution was to patch the binary data with some additional
      data structures (included as part of auto-generator source) but it was
      unnecessarily complicated.

      Chris suggested the idea of having a secondary batch and execute two batch
      buffers. It has clear advantages as we needn't touch the base golden 
batch,
      can customize secondary/auxiliary batch depending on Gen and can be 
carried
      in the driver with no dependencies.

      This patch adds support for this auxiliary batch which is inserted at the
      end of golden batch and is completely independent from it. Thanks to Mika
      for the preliminary review.

      v2: Strictly conform to the batch size requirements to cover Gen2 and
      add comments to clarify overflow check in macro (Chris, Mika).

      v3: aux_batch_offset was declared as u64, change it to u32 (Chris)

      sctp: fix src address selection if using secondary address

      This series improves the way SCTP chooses its src address so that the
      choosen one will always belong to the interface being used for output.

      v1->v2:
       - split out the refactoring from the fix itself
       - Doing a full reverse routing as in v1 is not necessary. Only looking
         for the interface that has the address and comparing its number is
         enough.

      sctp: fix src address selection if using secondary addresses

      In short, sctp is likely to incorrectly choose src address if socket is
      bound to secondary addresses. This patch fixes it by adding a new check
      that checks if such src address belongs to the interface that routing
      identified as output.

      This is enough to avoid rp_filter drops on remote peer.

      Details:

      Currently, sctp will do a routing attempt without specifying the src
      address and compare the returned value (preferred source) with the
      addresses that the socket is bound to. When using secondary addresses,
      this will not match.

      Then it will try specifying each of the addresses that the socket is
      bound to and re-routing, checking if that address is valid as src for
      that dst. Thing is, this check alone is weak:

          cache

      Even if you specify an interface:

      # ip r g 192.168.100.193 from 192.168.122.148 oif eth1
      192.168.100.193 from 192.168.122.148 dev eth1
          cache

      Although this would be valid, peers using rp_filter will drop such
      packets as their src doesn't match the routes for that interface.

      drm/i915: Add GuC-related header files

      intel_guc_fwif.h contains the subset of the GuC interface that we
      will need for submission of commands through the GuC. These MUST
      be kept in sync with the definitions used by the GuC firmware, and
      updates to this file will (or should) be autogenerated from the
      source files used to build the firmware. Editing this file is
      therefore not recommended.

      i915_guc_reg.h contains definitions of GuC-related hardware:
      registers, bitmasks, etc. These should match the BSpec.

      sched/idle: Move latency tracing stop/start calls deeper inside the idle 
loop

      Make sure to stop tracing only once we are past a point where
      all latency tracing events have been processed (irqs are not
      enabled again). This has the slight advantage of capturing more
      latency related events in the idle path, but most importantly it
      makes sure that latency tracing doesn't get re-enabled
      inadvertently when new events are coming in.

      This makes the irqsoff latency tracer useful again, as we stop
      capturing CPU sleep time as IRQ latency.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

      New features:

        - Allow filtering out of perf's PID via 'perf record --exclude-perf'. 
(Wang Nan)

        - 'perf trace' now supports syscall groups, like strace, i.e:

            $ trace -e file touch file

          Will expand 'file' into multiple, file related, syscalls. More work 
needed to
          add extra groups for other syscall groups, and also to complement 
what was
          added for the 'file' group, included as a proof of concept. (Arnaldo 
Carvalho de Melo)

        - Add lock_pi stresser to 'perf bench futex', to test the kernel code
          related to FUTEX_(UN)LOCK_PI. (Davidlohr Bueso)

      User visible fixes:

        - Apply --filter to all events in a glob matching, not just the last 
one. (Wang Nan)

      Documentation changes:

        - Document setting '-e pmu/period=N/' in the 'perf record' man page. 
(Kan Liang)

      Infrastructure changes:

        - 'perf probe' code simplifications and movements to separate files. 
(Masami Hiramatsu)

        - Fix makefile generation under 'dash'. (Sergei Trofimovich)

      This register is set via init_intel() at bootup. During resume,
      the secondary CPUs are brought online again and init_intel() is
      callled which re-initializes the register. The boot CPU however
      never reinitializes the register.

      Add a syscore callback to reinitialize the register for the boot CPU.

      ARM: dts: Extend exynos5420-pinctrl nodes using labels instead of paths

      A previously defined Device Tree node, can be extended either by defining
      a node using the same full path or by creating a label for the node and
      referencing to it.

      Using full paths is more error prone since if there was a typo error, a
      new node will be created instead of extending the node as it was desired.
      This will lead to run-time errors that could be hard to detect.

      A mistyped label on the other hand, will cause a dtc compile error which
      makes it easier to detect the mistake since happens at build-time instead.

      The dtc compiler combines all the defined nodes that have the same path
      so a device node definition can be in one file and later be extended in

      That's the case of the Exynos5420 pinctrl device nodes that are defined

      But since the exynos5420.dtsi file includes the exynos5420-pinctrl.dtsi
      before the pinctrl device nodes are actually defined, the definition of
      the pinctrl device nodes happens in exynos5420-pinctrl.dtsi and are
      extended in exynos5420.dtsi.

      That is the opposite of the original intention so even when there is no
      difference in practice, the exynos5420-pinctrl.dtsi include should be
      moved at the end of the exynos5420.dtsi file after the pinctrl device
      nodes have been already defined.

      This will also allow to later change the exynos5420-pinctrl.dtsi file
      to use labels instead of full paths to extend the pinctrl nodes. Since
      keeping the include at the top, would cause a dtc build error due the
      pinctrl labels not being defined yet.

      improve accuracy of timing in test_bpf and add two stress tests:
      - {skb->data[0], get_smp_processor_id} repeated 2k times
      - {skb->data[0], vlan_push} x 68 followed by {skb->data[0], vlan_pop} x 68

      1st test is useful to test performance of JIT implementation of BPF_LD_ABS
      together with BPF_CALL instructions.
      2nd test is stressing skb_vlan_push/pop logic together with skb->data 
access
      via BPF_LD_ABS insn which checks that re-caching of skb->data is done 
correctly.

      In order to call bpf_skb_vlan_push() from test_bpf.ko have to add
      three export_symbol_gpl.

      bpf: introduce bpf_skb_vlan_push/pop() helpers

      Allow eBPF programs attached to TC qdiscs call skb_vlan_push/pop via
      helper functions. These functions may change skb->data/hlen which are
      cached by some JITs to improve performance of ld_abs/ld_ind instructions.
      Therefore JITs need to recognize bpf_skb_vlan_push/pop() calls,
      re-compute header len and re-cache skb->data/hlen back into cpu registers.
      Note, skb->data/hlen are not directly accessible from the programs,
      so any changes to skb->data done either by these helpers or by other
      TC actions are safe.

      eBPF JIT supported by three architectures:
      - arm64 JIT is using bpf_load_pointer() without caching, so it's ok as-is.
      - x64 JIT re-caches skb->data/hlen unconditionally after vlan_push/pop 
calls
        (experiments showed that conditional re-caching is slower).
      - s390 JIT falls back to interpreter for now when bpf_skb_vlan_push() is 
present
        in the program (re-caching is tbd).

      These helpers allow more scalable handling of vlan from the programs.
      Instead of creating thousands of vlan netdevs on top of eth0 and attaching
      TC+ingress+bpf to all of them, the program can be attached to eth0 
directly
      and manipulate vlans as necessary.

      Intel Wired LAN Driver Updates 2015-07-17

      This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
      freescale, siena and dp83640.

      Jacob provides several patches to clarify the intended way to implement
      both SIOCSHWTSTAMP and ethtool's get_ts_info().  It is okay to support
      the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
      filters.

      Alex Duyck provides a igb patch to pull the time stamp from the fragment
      before it gets added to the skb, to avoid a possible issue in which the
      fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
      being pulled after the copybreak check.  Also provides a ixgbevf patch to
      fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
      the advantage that the fragment does not have to be modified after it is
      added to the skb.

      Fan provides patches for ixgbe/ixgbevf to set the receive hash type
      based on receive descriptor RSS type.

      Todd provides a fix for igb where on check for link on any media other
      than copper was not being detected since it was looking on the incorrect
      PHY page (due to the page being used gets switched before the function
      to check link gets executed).

      probed modes"), proper clock-frequency becomes mandatory for
      validating the mode of panel.  The display does not work if there is
      no mode validated. Also, this clock-frequency must be set
      appropriately for getting required frame rate.

      net: bcmgenet: PHY initialization rework

      This patch series reworks how we perform PHY initialization and resets in 
the
      GENET driver. Although this contains mostly fixes, some of the changes 
are a
      bit too intrusive to be backported to 'net' at the moment.

      Some of the motivations behind these changes were to reduce the time 
spent in how
      performing MDIO transactions, since it is better to perform then when we 
have
      interrupts enabled. This reduces the bring-up time of GENET from ~600 
msecs down
      to ~8 msecs, and about the same time for suspend/resume.

      Since I do not currently have a system which is not DT-aware, can you 
(Petri,
      Jaedon) give this a try and confirm things keep working as expected?

      net: bcmgenet: Remove init parameter from bcmgenet_mii_config

      Now that we have reworked the way we perform the PHY initialization, we
      no longer need to differentiate between init time vs. non-init time
      calls, just use a dev_info_once() print to print the PHY type.

      net: bcmgenet: Delay PHY initialization to bcmgenet_open()

      We are currently doing a full PHY initialization and even starting the
      pHY state machine during bcmgenet_mii_init() which is executed in the
      driver's probe function. This is convenient to determine whether we can
      attach to a proper PHY device but comes at the expense of spending up to
      10ms per MDIO transactions (to reach the waitqueue timeout), which slows
      things down.

      This also creates a sitaution where we end-up attaching twice to the
      PHY, which is not quite correct either.

      Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
      its error path accordingly.

      Avoid printing the message "attached PHY at address 1 [...]" every time
      we bring up/down the interface and remove this print since it duplicates
      what the PHY driver already does for us.

      net: bcmgenet: Determine PHY type before scanning MDIO bus

      Our internal GPHY might be powered off before we attempt scanning the
      MDIO bus and bind a driver to it. The way we are currently determining
      whether a PHY is internal or not is done *after* we have successfully
      matched its driver. If the PHY is powered down, it will not respond to
      the MDIO bus, so we will not be able to bind a driver to it.

      Our Device Tree for GENET interfaces specifies a "phy-mode" value:
      "internal" which tells if this internal uses an internal PHY or not.

      If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
      additional manual lookup, and if we find "internal" set the
      corresponding internal variable accordingly.

      Replace all uses of phy_is_internal() with a check against
      priv->internal_phy to avoid having to rely on whether or not
      priv->phydev is set correctly.

      We are currently disabling the GPHY interface during bcmgenet_close(),
      and attempting to power it back on during bcmgenet_open(). This works
      fine for the first time, because we called bcmgenet_mii_config() which
      took care of enabling the interface, however, bcmgenet_power_up() really
      needs to power on the GPHY for correctness.

      This will be particularly important as we want to move

      net: bcmgenet: Remove excessive PHY reset

      We are currently issuing multiple PHY resets during a suspend/resume,

      software reset by calling bcmgenet_mii_reset(). This is both unnecessary
      and can take as long as 10ms per MDIO transactions while we re-apply

      phy_resume() takes care of re-apply our workarounds in case we need any,
      and bcmgenet_power_up() does a PHY hardware reset, all of this is more
      than enough to guarantee that the PHY operates correctly.

      ====================
      stmmac clean up for 4.3 part1

      This patch set continues the conversion of the dwmac glue layers
      to more proper platform drivers. The first part of the patch set
      cleans up stmmac_platform a bit. Refactors code from the common
      probe function and exports two functions that will be used in
      the dwmac-* drivers.

      Second part converts two simple dwmac-* drivers to have their
      own probe function and use the exported functions. This brings
      us closer to point where stmmac_platform is only a library of
      common functions for the dwmac-* drivers to use.

      The plan next is:
       * add probe functions to the rest of the dwmac-* drivers
       * move probe function in stmmac_platform to dwmac-generic
       * remove struct stmmac_of_data and let those drivers
         that actually need match data handle it themselves
       * clean up include/linux/stmmac.h

      Note that this patch set has only been tested on lpc18xx so
      testing on other platforms is greatly appreciated.

      tipc: reduce locking scope during packet reception

      We convert packet/message reception according to the same principle
      we have been using for message sending and timeout handling:

      We move the function tipc_rcv() to node.c, hence handling the initial
      packet reception at the link aggregation level. The function grabs
      the node lock, selects the receiving link, and accesses it via a new
      call tipc_link_rcv(). This function appends buffers to the input
      queue for delivery upwards, but it may also append outgoing packets
      to the xmit queue, just as we do during regular message sending. The
      latter will happen when buffers are forwarded from the link backlog,
      or when retransmission is requested.

      Upon return of this function, and after having released the node lock,
      tipc_rcv() delivers/tranmsits the contents of those queues, but it may
      also perform actions such as link activation or reset, as indicated by
      the return flags from the link.

      This reduces the number of cpu cycles spent inside the node spinlock,
      and reduces contention on that lock.

      tipc: introduce node contact FSM

      The logics for determining when a node is permitted to establish
      and maintain contact with its peer node becomes non-trivial in the
      presence of multiple parallel links that may come and go independently.

      A known failure scenario is that one endpoint registers both its links
      to the peer lost, cleans up it binding table, and prepares for a table
      update once contact is re-establihed, while the other endpoint may
      see its links reset and re-established one by one, hence seeing
      no need to re-synchronize the binding table. To avoid this, a node
      must not allow re-establishing contact until it has confirmation that
      even the peer has lost both links.

      Currently, the mechanism for handling this consists of setting and
      resetting two state flags from different locations in the code. This
      solution is hard to understand and maintain. A closer analysis even
      reveals that it is not completely safe.

      In this commit we do instead introduce an FSM that keeps track of
      the conditions for when the node can establish and maintain links.
      It has six states and four events, and is strictly based on explicit
      knowledge about the own node's and the peer node's contact states.
      Only events leading to state change are shown as edges in the figure
      below.

      tipc: move link supervision timer to node level

      In our effort to move control of the links to the link aggregation
      layer, we move the perodic link supervision timer to struct tipc_node.
      The new timer is shared between all links belonging to the node, thus
      saving resources, while still kicking the FSM on both its pertaining
      links at each expiration.

      The current link timer and corresponding functions are removed.

      tipc: simplify link timer implementation

      We create a second, simpler, link timer function, tipc_link_timeout().
      The new function  makes use of the new FSM function introduced in the
      previous commit, and just like it, takes a buffer queue as parameter.
      It returns an event bit field and potentially a link protocol packet
      to the caller.

      The existing timer function, link_timeout(), is still needed for a
      while, so we redesign it to become a wrapper around the new function.

      tipc: improve link FSM implementation

      The link FSM implementation is currently unnecessarily complex.
      It sometimes checks for conditional state outside the FSM data
      before deciding next state, and often performs actions directly
      inside the FSM logics.

      In this commit, we create a second, simpler FSM implementation,
      that as far as possible acts only on states and events that it is
      strictly defined for, and postpone any actions until it is finished
      with its decisions. It also returns an event flag field and an a
      buffer queue which may potentially contain a protocol message to
      be sent by the caller.

      Unfortunately, we cannot yet make the FSM "clean", in the sense
      that its decisions are only based on FSM state and event, and that
      state changes happen only here. That will have to wait until the
      activate/reset logics has been cleaned up in a future commit.

      We also rename the link states as follows:

      WORKING_WORKING -> TIPC_LINK_WORKING
      WORKING_UNKNOWN -> TIPC_LINK_PROBING
      RESET_UNKNOWN   -> TIPC_LINK_RESETTING
      RESET_RESET     -> TIPC_LINK_ESTABLISHING

      The existing FSM function, link_state_event(), is still needed for
      a while, so we redesign it to make use of the new function.

      tipc: introduce new link protocol msg create function

      As a preparation for later changes, we introduce a new function
      tipc_link_build_proto_msg(). Instead of actually sending the created
      protocol message, it only creates it and adds it to the head of a
      skb queue provided by the caller.

      Since we still need the existing function tipc_link_protocol_xmit()
      for a while, we redesign it to make use of the new function.

      tipc: clean up definitions and usage of link flags

      The status flag LINK_STOPPED is not needed any more, since the
      mechanism for delayed deletion of links has been removed.
      Likewise, LINK_STARTED and LINK_START_EVT are unnecessary,
      because we can just as well start the link timer directly from
      inside tipc_link_create().

      We eliminate these flags in this commit.

      Instead of the above flags, we now introduce three new link modes,
      TIPC_LINK_OPEN, TIPC_LINK_BLOCKED and TIPC_LINK_TUNNEL. The values
      indicate whether, and in the case of TIPC_LINK_TUNNEL, which, messages
      the link is allowed to receive in this state. TIPC_LINK_BLOCKED also
      blocks timer-driven protocol messages to be sent out, and any change
      to the link FSM. Since the modes are mutually exclusive, we convert
      them to state values, and rename the 'flags' field in struct tipc_link
      to 'exec_mode'.

      Finally, we move the #defines for link FSM states and events from link.h
      into enums inside the file link.c, which is the real usage scope of
      these definitions.

      tipc: make media xmit call outside node spinlock context

      Currently, message sending is performed through a deep call chain,
      where the node spinlock is grabbed and held during a significant
      part of the transmission time. This is clearly detrimental to
      overall throughput performance; it would be better if we could send
      the message after the spinlock has been released.

      In this commit, we do instead let the call revert on the stack after
      the buffer chain has been added to the transmission queue, whereafter
      clones of the buffers are transmitted to the device layer outside the
      spinlock scope.

      As a further step in our effort to separate the roles of the node
      and link entities we also move the function tipc_link_xmit() to
      node.c, and rename it to tipc_node_xmit().

      tipc: change sk_buffer handling in tipc_link_xmit()

      When the function tipc_link_xmit() is given a buffer list for
      transmission, it currently consumes the list both when transmission
      is successful and when it fails, except for the special case when
      it encounters link congestion.

      This behavior is inconsistent, and needs to be corrected if we want
      to avoid problems in later commits in this series.

      In this commit, we change this to let the function consume the list
      only when transmission is successful, and leave the list with the
      sender in all other cases. We also modifiy the socket code so that
      it adapts to this change, i.e., purges the list when a non-congestion
      error code is returned.

      tipc: use bearer index when looking up active links

      struct tipc_node currently holds two arrays of link pointers; one,
      indexed by bearer identity, which contains all links irrespective of
      current state, and one two-slot array for the currently active link
      or links. The latter array contains direct pointers into the elements
      of the former. This has the effect that we cannot know the bearer id of
      a link when accessing it via the "active_links[]" array without actually
      dereferencing the pointer, something we want to avoid in some cases.

      In this commit, we do instead store the bearer identity in the
      "active_links" array, and use this as an index to find the right element
      in the overall link entry array. This change should be seen as a
      preparation for the later commits in this series.

      tipc: move link input queue to tipc_node

      At present, the link input queue and the name distributor receive
      queues are fields aggregated in struct tipc_link. This is a hazard,
      because a link might be deleted while a receiving socket still keeps
      reference to one of the queues.

      This commit fixes this bug. However, rather than adding yet another
      reference counter to the critical data path, we move the two queues
      to safe ground inside struct tipc_node, which is already protected, and
      let the link code only handle references to the queues. This is also
      in line with planned later changes in this area.

      This patch uses type unsigned long, instead of long, to format the ip

      ftrace: Fix function_graph duration spacing with 7-digits

      Jungseok Lee noticed the following:

      Currently, row's width of 7-digit duration numbers not aligned with
      other cases like the following example.

       3) $ 3999884 us |      }
       3)               |      finish_task_switch() {
       3)   0.365 us    |        _raw_spin_unlock_irq();
       3)   3.333 us    |      }
       3) $ 3999976 us |    }
       3) $ 3999979 us |  } /* schedule */

      As adding a single white space in case of 7-digit numbers, the format
      could be unified easily as follows.

       3) $ 2237472 us  |      }
       3)               |      finish_task_switch() {
       3)   0.364 us    |        _raw_spin_unlock_irq();
       3)   3.125 us    |      }
       3) $ 2237556 us  |    }
       3) $ 2237559 us  |  } /* schedule */

      Instead of making a special case for 7-digit numbers, the logic
      of the len and the space loop is slightly modified to make the
      two cases have the same format.

      tracing: Clean up stack tracing and fix fentry updates

      Akashi Takahiro was porting the stack tracer to arm64 and found some
      issues with it. One was that it repeats the top function, due to the
      stack frame added by the mcount caller and added by itself. This
      was added when fentry came in, and before fentry created its own stack
      frame. But x86's fentry now creates its own stack frame, and there's
      no need to insert the function again.

      This also cleans up the code a bit, where it doesn't need to do something
      special for fentry, and doesn't include insertion of a duplicate
      entry for the called function being traced.

      Now that events only add time extends after it is committed, in case
      an event comes in before it can discard the allocated event, the time
      extend needs to be stored within the event. If the event is bigger
      than then size needed for the time extend, padding must be added.
      The minimum padding size is 8 bytes. Thus if the event is 12 bytes
      (size of time extend + 4), there will not be enough room to add both

      ring-buffer: Get timestamp after event is allocated

      Move the capturing of the timestamp to after an event is allocated.
      If the event is not a commit (where it is an event that preempted
      another event), then no timestamp is needed, because the delta of
      nested events is always zero.

      If the event starts on a new page, no delta needs to be calculated
      as the full timestamp will be added to the page header, and the
      event will have a delta of zero.

      Now if the event requires a time extend (the delta does not fit
      in the 27 bit delta slot in the header), then the event is discarded,
      the length is extended to hold the TIME_EXTEND event that allows for
      a 59 bit delta, and the commit is tried again.

      If the event can't be discarded (another event came in after it),
      then the TIME_EXTEND is added directly to the allocated event and
      the rest of the event is given padding.

      tracing: Fix for non-continuous cpu ids

      Currently exception occures due to access beyond buffer_iter
      range while using index of cpu bigger than num_possible_cpus().
      Below there is an example for such exception when we use
      cpus 0,1,16,17.

      In order to fix buffer allocation size for non-continuous cpu ids
      we allocate according to the max cpu id and not according to the

      When detecting EEH error on non-existing PE, including the reserved

      Merge branch 'offload_fwd_mark'

      Scott Feldman says:

      ====================
      switchdev: avoid duplicate packet forwarding

      v3:

       - Per Nicolas Dichtel review: remove errant empty union.

      v2:

       - Per davem review: in sk_buff, union fwd_mark with secmark to save space
         since features appear to be mutually exclusive.
       - Per Simon Horman review:
         - fix grammar in switchdev.txt wrt fwd_mark
         - remove some unrelated changes that snuck in

      v1:

      This patchset was previously submitted as RFC.  No changes from the last
      version (v2) sent under RFC.  Including RFC version history here for 
reference.

      RFC v2:

       - s/fwd_mark/offload_fwd_mark
       - use consume_skb rather than kfree_skb when dropping pkt on egress.
       - Use Jiri's suggestion to use ifindex of one of the ports in a group
         as the mark for all the ports in the group.  This can be done with
         no additional storage (no hashtable from v1).  To pull it off, we
         need some simple recursive routines to walk the netdev tree ensuring
         all leaves in the tree (ports) in the same group (e.g. bridge)
         belonging to the same switch device will have the same offload fwd 
mark.
         Maybe someone sees a better design for the recusive routines?  They're
         not too bad, and should cover the stacked driver cases.

      RFC v1:

      With switchdev support for offloading L2/L3 forwarding data path to a
      switch device, we have a general problem where both the device and the
      kernel may forward the packet, resulting in duplicate packets on the wire.
      Anytime a packet is forwarded by the device and a copy is sent to the CPU,
      there is potential for duplicate forwarding, as the kernel may also do a
      forwarding lookup and send the packet on the wire.

      The specific problem this patch series is interested in solving is 
avoiding
      duplicate packets on bridged ports.  There was a previous RFC from Roopa
      (http://marc.info/?l=linux-netdev&m=142687073314252&w=2) to address this
      problem, but didn't solve the problem of mixed ports in the bridge from
      different devices; there was no way to exclude some ports from forwarding
      and include others.  This RFC solves that problem by tagging the 
ingressing
      packet with a unique mark, and then comparing the packet mark with the
      egress port mark, and skip forwarding when there is a match.  For the 
mixed
      ports bridge case, only those ports with matching marks are skipped.

      The switchdev port driver must do two things:

      1) Generate a fwd_mark for each switch port, using some unique key of the
         switch device (and optionally port).  This is done when the port netdev
         is registered or if the port's group membership changes (joins/leaves
         a bridge, for example).

      2) On packet ingress from port, mark the skb with the ingress port's
         fwd_mark.  If the device supports it, it's useful to only mark skbs
         which were already forwarded by the device.  If the device does not
         support such indication, all skbs can be marked, even if they're
         local dst.

      Two new 32-bit fields are added to struct sk_buff and struct netdevice to
      hold the fwd_mark.  I've wrapped these with CONFIG_NET_SWITCHDEV for now. 
I
      tried using skb->mark for this purpose, but ebtables can overwrite the
      skb->mark before the bridge gets it, so that will not work.

      In general, this fwd_mark can be used for any case where a packet is
      forwarded by the device and a copy is sent to the CPU, to avoid the kernel
      re-forwarding the packet.  sFlow is another use-case that comes to mind,
      but I haven't explored the details.

      rocker: add offload_fwd_mark support

      If device flags ingress packet as "fwd offload", mark the
      skb->offlaod_fwd_mark using the ingress port's dev->offlaod_fwd_mark.  
This
      will be the hint to the kernel that this packet has already been forwarded
      by device to egress ports matching skb->offlaod_fwd_mark.

      For rocker, derive port dev->offlaod_fwd_mark based on device switch ID 
and
      port ifindex.  If port is bridged, use the bridge ifindex rather than the
      port ifindex.

      switchdev: add offload_fwd_mark generator helper

      skb->offload_fwd_mark and dev->offload_fwd_mark are 32-bit and should be
      unique for device and may even be unique for a sub-set of ports within
      device, so add switchdev helper function to generate unique marks based on
      port's switch ID and group_ifindex.  group_ifindex would typically be the
      container dev's ifindex, such as the bridge's ifindex.

      The generator uses a global hash table to store offload_fwd_marks hashed 
by
      {switch ID, group_ifindex} key.

      Just before queuing skb for xmit on port, check if skb has been marked by
      switchdev port driver as already fordwarded by device.  If so, drop skb.  
A
      non-zero skb->offload_fwd_mark field is set by the switchdev port
      driver/device on ingress to indicate the skb has already been forwarded by
      the device to egress ports with matching dev->skb_mark.  The switchdev

      ACPI / processor: remove leftover __refdata annotations

      The processor_handler structure does not reference any __init / __exit
      code or data. Therefore the __refdata annotation is not needed. It used
      to be prior to commit fe7bf106ebc2 ("acpi: delete __cpuinit usage from
      all acpi files") due to the __cpuinit annotation of acpi_processor_add().
      But with that commit in place that requirement has gone.

      The same is true for the acpi_cpu_notifier notifier block.
      acpi_cpu_soft_notify() used to be marked __cpuinit but lost its
      annotation in the above mentioned commit as well. Therefore the __refdata
      annotation isn't needed there either.

      Just drop the unneded __refdata annotations to be able to catch future
      section mismatches.

      perf bench futex: Add lock_pi stresser

      Allows a way of measuring low level kernel implementation of 
FUTEX_LOCK_PI and
      FUTEX_UNLOCK_PI.

      The program comes in two flavors:

      (i) single futex (default), all threads contend on the same uaddr.  For 
the
      sake of the benchmark, we call into kernel space even when the lock is
      uncontended.  The kernel will set it to TID, any waters that come in and
      contend for the pi futex will be handled respectively by the kernel.

      (ii) -M option for multiple futexes, each thread deals with its own 
futex. This
      is a trivial scenario and only measures kernel handling of 0->TID 
transition.

      perf record: Allow filtering perf's pid via --exclude-perf

      This patch allows 'perf record' to exclude events issued by perf itself
      by '--exclude-perf' option.

      Before this patch, when doing something like:

       # perf record -a -e syscalls:sys_enter_write <cmd>

      One could easily get result like this:

       # /tmp/perf report --stdio
       ...
        # Overhead  Command  Shared Object       Symbol
        # ........  .......  ..................  ....................
        #
            99.99%  perf     libpthread-2.18.so  [.] __write_nocancel
            0.01%   ls       libc-2.18.so        [.] write
            0.01%   sshd     libc-2.18.so        [.] write
       ...

      Where most events are generated by perf itself.

      A shell trick can be done to filter perf itself out:

       # cat << EOF > ./tmp
       > #!/bin/sh
       > exec perf record -e ... --filter="common_pid != \$\$" -a sleep 10
       > EOF
       # chmod a+x ./tmp
       # ./tmp

      However, doing so is user unfriendly.

      This patch extracts evsel iteration framework introduced by patch 'perf
      record: Apply filter to all events in a glob matching' into
      foreach_evsel_in_last_glob(), and makes exclude_perf() function append
      new filter expression to each evsel selected by a '-e' selector.

      To avoid losing filters if user pass '--filter' after '--exclude-perf',
      this patch uses perf_evsel__append_filter() in both case, instead of
      perf_evsel__set_filter() which removes old filter. As a side effect, now
      it is possible to use multiple '--filter' option for one selector. They
      are combinded with '&&'.

      net/ipv6: update flowi6_oif in ip6_dst_lookup_flow if not set

      Newly created flows don't have flowi6_oif set (at least if the
      associated socket is not interface-bound). This leads to a mismatch in
      __xfrm6_selector_match() for policies which specify an interface in the
      selector (sel->ifindex != 0).

      Backtracing shows this happens in code-paths originating from e.g.
      ip6_datagram_connect(), rawv6_sendmsg() or tcp_v6_connect(). (UDP was
      not tested for.)

      In summary, this patch fixes policy matching on outgoing interface for
      locally generated packets.

      ebpf: add helper to retrieve net_cls's classid cookie

      It would be very useful to retrieve the net_cls's classid from an eBPF
      program to allow for a more fine-grained classification, it could be
      directly used or in conjunction with additional policies. I.e. docker,
      but also tooling such as cgexec, can easily run applications via net_cls
      cgroups:

        cgcreate -g net_cls:/foo
        echo 42 > foo/net_cls.classid
        cgexec -g net_cls:foo <prog>

      Thus, their respecitve classid cookie of foo can then be looked up on
      the egress path to apply further policies. The helper is desigend such
      that a non-zero value returns the cgroup id.

      enic: allow adaptive coalesce setting for msi/legacy intr

      * Allow setting of adaptive coalescing setting for all types of interrupt.

      * In msi & legacy intr, we use single interrupt for rx & tx. In this case
        tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
        Do not display tx_coal values for msi/intx. And do not allow user to set
        this as well.

      * Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
        For other values, driver does not return error. So ethtool succeeds for
        unsupported values. Introduce enic_coalesce_valid() function to validate
        the coalescing values.

      * If user requests for coalesce value greater than what adaptor supports,
        driver uses the max value. We should at least log this.

      Kernel coding conventions frown upon having large nontrivial

      As these functions are re-homed into a .c file, be sure that

      constants.

      svcrdma: Fix send_reply() scatter/gather set-up

      The Linux NFS server returns garbage in the data payload of inline
      NFS/RDMA READ replies. These are READs of under 1000 bytes or so
      where the client has not provided either a reply chunk or a write
      list.

      The NFS server delivers the data payload for an NFS READ reply to
      the transport in an xdr_buf page list. If the NFS client did not
      provide a reply chunk or a write list, send_reply() is supposed to
      set up a separate sge for the page containing the READ data, and
      another sge for XDR padding if needed, then post all of the sges via
      a single SEND Work Request.

      The problem is send_reply() does not advance through the xdr_buf
      when setting up scatter/gather entries for SEND WR. It always calls
      dma_map_xdr with xdr_off set to zero. When there's more than one
      sge, dma_map_xdr() sets up the SEND sge's so they all point to the
      xdr_buf's head.

      The current Linux NFS/RDMA client always provides a reply chunk or
      a write list when performing an NFS READ over RDMA. Therefore, it
      does not exercise this particular case. The Linux server has never
      had to use more than one extra sge for building RPC/RDMA replies
      with a Linux client.

      However, an NFS/RDMA client _is_ allowed to send small NFS READs
      without setting up a write list or reply chunk. The NFS READ reply
      fits entirely within the inline reply buffer in this case. This is
      perhaps a more efficient way of performing NFS READs that the Linux
      NFS/RDMA client may some day adopt.

      NFS/RDMA Release resources in svcrdma when device is removed

      When removing underlying RDMA device, the rmmod will hang forever if there
      are any outstanding NFS/RDMA client mounts. The outstanding NFS/RDMA 
counts
      could also prevent the server from shutting down. Further debugging shows
      that the existing connections are not teared down and resource are not
      released when receiving RDMA_CM_EVENT_DEVICE_REMOVAL event. It seems the
      original code missing svc_xprt_put() in RDMA_CM_EVENT_REMOVAL event 
handler
      thus svc_xprt_free is never invoked to release the existing connection
      resources.

      The patch has been passed removing, adding device back and forth without
      stopping NFS/RDMA service. This will also allow a device to be unplugged
      and swapped out without shutting down NFS service.

      perf record: Apply filter to all events in a glob matching

      There is an old problem in perf's filter applying which first posted at
      Sep. 2014 at https://lkml.org/lkml/2014/9/9/944 that, if passing
      multiple events in a glob matching expression in cmdline then add
      '--filter' after them, the filter will be applied on only the last one.

      For example:

       # dd if=/dev/zero of=/dev/null &
       [1] 464
       # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' 
sleep 0.1
       [ perf record: Woken up 1 times to write data ]
       [ perf record: Captured and wrote 0.239 MB perf.data (2094 samples) ]
       # perf report --stdio | tee
       ...
       # Samples: 2K of event 'syscalls:sys_enter_read'
       # Event count (approx.): 2092
       ...
       # Samples: 2  of event 'syscalls:sys_exit_read'
       # Event count (approx.): 2
       ...

      In this example, filter only applied on 'syscalls:sys_exit_read', and
      there's no way to set filter for ''syscalls:sys_enter_read'.

      This patch adds a 'cmdline_group_boundary' for 'struct evsel', and
      apply filter on all events between two boundary marks.

      After applying this patch:

       # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' 
sleep 0.1
       [ perf record: Woken up 1 times to write data ]
       [ perf record: Captured and wrote 0.031 MB perf.data (3 samples) ]
       # perf report --stdio | tee
       ...
       # Samples: 1  of event 'syscalls:sys_enter_read'
       # Event count (approx.): 1
       ...
       # Samples: 2  of event 'syscalls:sys_exit_read'
       # Event count (approx.): 2
       ...

        rmdir
        stat
        statfs
        symlink
        unlink
        $

      Then, on a quiet desktop, try running this and then moving your mouse to
      see the deluge of mouse related activity:

        # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'

      clk: ux500: Remove clk.h and clkdev.h includes

      Clock provider drivers generally shouldn't include clk.h because
      it's the consumer API. Remove the include here because this is a
      provider driver. Also remove clkdev.h in files that aren't using
      it.

      Now that we have more details about the TIMING_CFG register layout

      regmap: debugfs: Allow writes to cache state settings

      Allow the user to write the cache_only and cache_bypass settings.
      This can be useful for debugging.

      Since this can lead to the hardware getting out-of-sync with the
      cache, at least for the period that the cache state is forced, the
      kernel is tainted and the action is recorded in the kernel log.

      When disabling cache_only through debugfs a cache sync will be performed.

      perf strlist: Allow substitutions from file contents in a given directory

      So, if we have an strlist equal to:

         "file,close"

      And we call it as:

         struct strlist_config *config = { .dirname = "~/strace/groups", };
         struct strlist *slist = strlist__new("file, close", &config);

      And we have:
        $ cat ~/strace/groups/file
        access
        open
        openat
        statfs

      Then the resulting strlist will have these contents:

        [ "access", "open", "openat", "statfs", "close" ]

      This will be used to implement strace syscall groups in 'perf trace',
      but can be used in some other tool, thus being implemented in 'strlist'.

      iio: dht11: Use new function ktime_get_resolution_ns()

      This cleans up the most ugly workaround in this driver. There are no
      functional changes yet in the decoding algorithm, but we improve the
      following things:
       * Get rid of spurious warning messages on systems with fast HRTIMER.
       * If the clock is not fast enough for decoding to work, we give
         up immediately.
       * In that case we return EAGAIN instead of EIO, so it's easier to
         discriminate causes of failure.

      Returning EAGAIN is somewhat controversial: It's technically correct
      as a faster clock might become available. OTOH once all clocks are
      enabled this is a permanent error. There is no ECLOCKTOOSLOW error
      code.

      iio: adc: vf610: Determine sampling frequencies by using minimum sample 
time

      The driver currently does not take into account the minimum sample time
      as per the Figure 6-8 Chapter 9.1.1 12-bit ADC electrical characteristics.
      We set a static amount of cycles instead of considering the sample time
      as a given value, which depends on hardware characteristics.

      Determine sampling frequencies by first reading the device tree property
      node and then calculating the required Long Sample Time Adder (LSTAdder)
      value, based on the ADC clock frequency and sample time value obtained
      from the device tree. This LSTAdder value is then used for calculating
      the sampling frequencies possible.

      In case the sample time property is not specified through the device
      tree, a safe default value of 1000ns is assumed.

      regulator: rk808: fixed the overshoot when adjust voltage

      There is a overshoot in DCDC1/DCDC2, we have 2 method to workaround:
      1st is use dvs pin to switch the voltage between value in BUCKn_ON_VSEL
      and BUCKn_DVS_VSEL. If DVS pin is inactive, the voltage of DCDC1/DCDC2
      are controlled by BUCKn_ON_VSEL, when we pull dvs1/dvs2 pin to active,
      they would be controlled by BUCKn_DVS_VSEL. In this case, the ramp rate
      is same as the value programmed in BUCKn_RATE, and the fastest rate is
      10mv/us.
      2nd method is gradual adjustment, adjust the voltage to a target value
      step by step via i2c, each step is set to 100 mA. If you write the
      voltage directly using an i2c write the rk808 will always ramp as fast
      as it possibly can, about 100mv/us.

      ASoC: ux500: adjust devm usage

      The explicit call to devm_regulator_put in the probe and remove functions
      does not seem to be necessary.  In particular, the functions
      prcmu_qos_remove_requirement and ux500_msp_i2s_cleanup_msp in the remove
      function seem to do nothing that can interfere with devm_regulator_put,
      making it safe to allow devm_regulator_put to occur after the end of the
      remove function.

      Convert the calls to clk_get to devm_clk_get, and remove the corresponding
      calls to clk_put in the probe and remove functions.

      Replace various gotos by direct returns, and drop unneeded labels.

      We check the ATS state (enabled/disabled) and fetch the PCI ATS Invalidate
      Queue Depth in performance-sensitive paths.  It's easy to cache these,
      which removes dependencies on PCI.

      Remember the ATS enabled state.  When enabling, read the queue depth once
      and cache it in the device_domain_info struct.  This is similar to what
      amd_iommu.c does.

      power: reset: at91: add sama5d3 reset function

      This patch introduces a new compatible string: "atmel,sama5d3-rstc" and
      new reset function for sama5d3 and later chips.

      As in sama5d3 or later chips, we don't have to shutdown the DDR
      controller before reset. Shutdown the DDR controller before reset is a
      workaround to avoid DDR signal driving the bus, but since sama5d3 and
      later chips there is no such a conflict.

      So in this patch:
         1. the sama5d3 reset function only need to write the rstc register
      and return.
         2. we can remove the code related with sama5d3 DDR controller as
      we don't use it at all.

      futex: Fault/error injection capabilities

      Although futexes are well known for being a royal pita,
      we really have very little debugging capabilities - except
      for relying on tglx's eye half the time.

      By simply making use of the existing fault-injection machinery,
      we can improve this situation, allowing generating artificial
      uaddress faults and deadlock scenarios. Of course, when this is
      disabled in production systems, the overhead for failure checks
      is practically zero -- so this is very cheap at the same time.
      Future work would be nice to now enhance trinity to make use of
      this.

      There is a special tunable 'ignore-private', which can filter
      out private futexes. Given the tsk->make_it_fail filter and
      this option, pi futexes can be narrowed down pretty closely.

      staging: ozwpan: Fix hrtimer wreckage

      oz_timer_add() modifies the expiry value of an active timer, which
      results in data corruption.

      Use hrtimer_start() and remove the silly conditional.

      While at it use the proper helper function to convert milliseconds to
      ktime.

      This reverts commit 6adfb1ef106bfe4b5ecb8bd75c4d037741d28a48.

      Ironlake RPS code runs under an irqsave spinlock and hence sleeping
      isn't allowed. Not a this long delay while blocking irqs isn't great
      at all, but fixing the locking scheme is a lot more involved.

      So just revert for now.

      drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface

      This patch adds the gfx8 interface file between amdgpu and amdkfd. This
      interface file is currently in use when running on a Carrizo-based
      system.

      The interface itself is represented by a pointer to struct
      kfd_dev. The pointer is located inside amdgpu_device structure.

      All the register accesses that amdkfd need are done using this
      interface. This allows us to avoid direct register accesses in
      amdkfd proper, while also allows us to avoid locking between
      amdkfd and amdgpu.

      The single exception is the doorbells that are used in both of
      the drivers. However, because they are located in separate pci
      bar pages, the danger of sharing registers between the drivers
      is minimal.

      Having said that, we are planning to move the doorbells as well
      to amdgpu.

      This interface file was used for bring-up of amdkfd on amdgpu and for
      debugging purposes. For users who would like to run HSA on Kaveri, please
      use the radeon graphic driver.

      Note: CONFIG_DRM_AMDGPU_CIK must be selected for amdgpu to handle Kaveri.

      drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd interface

      This patch adds an interface file between amdgpu and amdkfd. This
      interface file is H/W agnostic, thus containing functions that
      operate the same for any AMD APU/GPU H/W generation.

      The functions in this interface mirror (some) of the functions in
      radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
      are:

      - amdgpu_amdkfd_init - initialize the amdkfd module
      - amdgpu_amdkfd_load_interface - load the H/W interface according to the
        currently probed device
      - amdgpu_amdkfd_device_probe - probe the device in amdkfd
      - amdgpu_amdkfd_device_init - initialize the device in amdkfd
      - amdgpu_amdkfd_interrupt - call the ISR of amdkfd
      - amdgpu_amdkfd_suspend - suspend callback from amdgpu
      - amdgpu_amdkfd_resume - resume callback from amdgpu

      This patch also modifies the relevant amdgpu files, to use this new
      interface.

      In order to provide a channel name to in kernel consumers add the
      datasheet names for every usable AD channel. Since the channel names
      differ between i.MX23 and i.MX28, we need to separate the channel

      ARM: pxa: transition to dmaengine phase 1

      In order to slowly transition pxa to dmaengine, the legacy code will now
      rely on dmaengine to request a channel.

      This implies that PXA architecture selects DMADEVICES and PXA_DMA,
      which is not pretty. Yet it enables PXA drivers to be ported one by one,
      with part of them using dmaengine, and the other part using the legacy
      code.

      ixgbe: Don't report flow director filter's status

      For two reasons I want to disable this:
      1. Not any part actually check the report status(Alexander Duyck)
      2. To report hash value of a packet to stack,
         RSS -> 32bits hash value
         Perfect match fdir filter -> 13bits hash value
         Hashed-based fdir filter -> 31bits hash value

         fdir filter might hash on masked tuples for IP address,
         so it's still not desirable for usage.

      So for now, just stick to RSS 32bits hash value.

      igb: Pull timestamp from fragment before adding it to skb

      This change makes it so that we pull the timestamp from the fragment 
before
      we add it to the skb.  By doing this we can avoid a possible issue in 
which
      the fragment can possibly be less than IGB_RX_HDR_LEN due to the timestamp
      being pulled after the copybreak check.

      While making this change I realized we could also pull the rest of the
      igb_pull_tail function into igb_add_rx_frag since in the case of igb,
      unlike ixgbe, we are able to unmap the entire buffer before calling
      add_rx_frag so merging the two allows for sharing of code between the two
      merged functions.

      clarify implementation of ethtool's get_ts_info op

      This patch adds some clarification about the intended way to implement
      both SIOCSHWTSTAMP and ethtool's get_ts_info. The HWTSTAMP API has
      several Rx filters which are very specific, as well as more general
      filters. The specific filters really only exist to support some broken
      hardware which can't fully implement the generic filters. This patch
      adds clarification that it is okay to support the specific filters in
      SIOCSHWTSTAMP by upscaling them to the generic filters. In addition,
      update the header for ethtool_ts_info to specify that drivers ought to
      only report the filters they support without upscaling in this manner.

      rcu: Add fastpath bypassing funnel locking

      In the common case, there will be only one expedited grace period in
      the system at a given time, in which case it is not helpful to use
      funnel locking.  This commit therefore adds a fastpath that bypasses
      funnel locking when the root ->exp_funnel_mutex is not held.

      rcu: Rename RCU_GP_DONE_FQS to RCU_GP_DOING_FQS

      The grace-period kthread sleeps waiting to do a force-quiescent-state
      scan, and when awakened sets rsp->gp_state to RCU_GP_DONE_FQS.
      However, this is confusing because the kthread has not done the
      force-quiescent-state, but is instead just starting to do it.  This commit
      therefore renames RCU_GP_DONE_FQS to RCU_GP_DOING_FQS in order to make
      things a bit easier on reviewers.

      rcu: Pull out wait_event*() condition into helper function

      The condition for the wait_event_interruptible_timeout() that waits
      to do the next force-quiescent-state scan is a bit ornate:

        ((gf = READ_ONCE(rsp->gp_flags)) &
         RCU_GP_FLAG_FQS) ||
        (!READ_ONCE(rnp->qsmask) &&

      rcu: Add stall warnings to synchronize_sched_expedited()

      Although synchronize_sched_expedited() historically has no RCU CPU stall
      warnings, the availability of the rcupdate.rcu_expedited boot parameter
      invalidates the old assumption that synchronize_sched()'s stall warnings

      synchronize_sched_expedited().

      rcu: Extend expedited funnel locking to rcu_data structure

      The strictly rcu_node based funnel-locking scheme works well in many
      cases, but systems with CONFIG_RCU_FANOUT_LEAF=64 won't necessarily get
      all that much concurrency.  This commit therefore extends the funnel
      locking into the per-CPU rcu_data structure, providing concurrency equal
      to the number of CPUs.

      rcu: Consolidate last open-coded expedited memory barrier

      One of the requirements on RCU grace periods is that if there is a
      causal chain of operations that starts after one grace period and
      ends before another grace period, then the two grace periods must
      be serialized.  There has been (and might still be) code that relies
      on this, for example, certain types of reference-counting code that
      does a call_rcu() within an RCU callback function.

      This requirement is why there is an smp_mb() at the end of both
      synchronize_sched_expedited() and synchronize_rcu_expedited().
      However, this is the only smp_mb() in these functions, so it would
      be nicer to consolidate it into rcu_exp_gp_seq_end().  This commit
      does just that.

      rcu: Make synchronize_rcu_expedited() use sequence-counter scheme

      Although synchronize_rcu_expedited() uses a sequence-counter scheme, it
      is based on a single increment per grace period, which means that tasks
      piggybacking off of concurrent grace periods may be forced to wait longer
      than necessary.  This commit therefore applies the new sequence-count
      functions developed for synchronize_sched_expedited() to speed things
      up a bit and to consolidate the sequence-counter implementation.

      rcu: Abstract sequence counting from synchronize_sched_expedited()

      This commit creates rcu_exp_gp_seq_start() and rcu_exp_gp_seq_end() to
      bracket an expedited grace period, rcu_exp_gp_seq_snap() to snapshot the
      sequence counter, and rcu_exp_gp_seq_done() to check to see if a full
      expedited grace period has elapsed since the snapshot.  These will be
      applied to synchronize_rcu_expedited().  These are defined in terms of
      underlying rcu_seq_start(), rcu_seq_end(), rcu_seq_snap(), rcu_seq_done(),
      which will be applied to _rcu_barrier().

      One reason that this commit doesn't use the seqcount primitives themselves
      is that the smp_wmb() in those primitive is insufficient due to the fact
      that expedited grace periods do reads as well as writes.  In addition,
      the read-side seqcount primitives detect a potentially partial change,
      where the expedited primitives instead need a guaranteed full change.

      rcu: Make expedited GP CPU stoppage asynchronous

      Sequentially stopping the CPUs slows down expedited grace periods by
      at least a factor of two, based on rcutorture's grace-period-per-second
      rate.  This is a conservative measure because rcutorture uses unusually
      long RCU read-side critical sections and because rcutorture periodically
      quiesces the system in order to test RCU's ability to ramp down to and
      up from the idle state.  This commit therefore replaces the stop_one_cpu()
      with stop_one_cpu_nowait(), using an atomic-counter scheme to determine
      when all CPUs have passed through the stopped state.

      rcu: Rework synchronize_sched_expedited() counter handling

      Now that synchronize_sched_expedited() have a mutex, it can use simpler
      work-already-done detection scheme.  This commit simplifies this scheme
      by using something similar to the sequence-locking counter scheme.
      A counter is incremented before and after each grace period, so that
      the counter is odd in the midst of the grace period and even otherwise.
      So if the counter has advanced to the second even number that is
      greater than or equal to the snapshot, the required grace period has
      already happened.

      rcu: Switch synchronize_sched_expedited() to stop_one_cpu()

      The synchronize_sched_expedited() currently invokes try_stop_cpus(),
      which schedules the stopper kthreads on each online non-idle CPU,
      and waits until all those kthreads are running before letting any
      of them stop.  This is disastrous for real-time workloads, which
      get hit with a preemption that is as long as the longest scheduling
      latency on any CPU, including any non-realtime housekeeping CPUs.
      This commit therefore switches to using stop_one_cpu() on each CPU
      in turn.  This avoids inflicting the worst-case scheduling latency
      on the worst-case CPU onto all other CPUs, and also simplifies the
      code a little bit.

      Follow-up commits will simplify the counter-snapshotting algorithm
      and convert a number of the counters that are now protected by the
      new ->expedited_mutex to non-atomic.

      rcu: Shut up bogus gcc array bounds warning

      Because gcc does not realize a loop would not be entered ever
      (i.e. in case of rcu_num_lvls == 1):

        for (i = 1; i < rcu_num_lvls; i++)
          rsp->level[i] = rsp->level[i - 1] + levelcnt[i - 1];

      some compiler (pre- 5.x?) versions give a bogus warning:

        kernel/rcu/tree.c: In function â??rcu_init_one.isra.55â??:
        kernel/rcu/tree.c:4108:13: warning: array subscript is above array 
bounds [-Warray-bounds]
           rsp->level[i] = rsp->level[i - 1] + rsp->levelcnt[i - 1];
                     ^
      Fix that warning by adding an extra item to rcu_state::level[]
      array. Once the bogus warning is fixed in gcc and kernel drops
      support of older versions, the dummy item may be removed from
      the array.

      pinctrl: add support for Qualcomm Technologies QDF2xxx ARM64 SoCs

      Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs,
      which uses the Qualcomm Technologies TLMM pinctrl/gpio device.  This
      driver is probed via ACPI and uses the pinctrl-msm.c backend driver.

      This driver is intended to be used only an ACPI-enabled system.  As such,
      UEFI will handle all pin control configuration, so this driver does not
      provide pin control functions.  It is effectively a GPIO-only driver.

      regmap: Create a new struct reg_sequence for register sequences

      In order to allow us to start adding extra annotations for sequences
      without bloating register default tables duplicate the structure under
      the new name reg_sequence and update the APIs to use that instead of
      reg_default.

      spi: mpc512x-psc: add support for Freescale MPC5125

      The register layout of the PSC devices differ between MPC5121 and
      MPC5125, but the registers are named nearly identical and their purpose
      is similar enough ("freescale identical") such that substituting
      mpc52xx_psc by mpc5125_psc is nearly enough to make the driver work on
      MPC5125. To keep supporting MPC5121 this patch introduces a cpp
      macro to select the right struct that defines the register layout.

      This driver makes it possible to configure the static memory
      chip selects on the ARM PL172 MultiPort Memory Controller
      from a set of properties in DT. Configuration of dynamic
      memory is not supported and is left to the boot loader.

      The intended usage is to setup timing and configuration for

      are probed by a driver.

      arm64: dts: add Rockchip rk3368 core dtsi and board dts for the r88 board

      In terms of peripherals the rk3368 is quite similar to the rk3288, which
      makes it possible to have a lot basic components working in the first go.
      More to follow once I tracked down all the tiny differences that still
      exist in some parts.

      With these dts files, the R88 board is able to boot from an attached
      usb device and most likely from its emmc too, if the emmc uses a standard
      partition table instead of Rockchip's own one - the emmc itself is
      detected correctly.

      ext4 crypto: check for too-short encrypted file names

      An encrypted file name should never be shorter than an 16 bytes, the
      AES block size.  The 3.10 crypto layer will oops and crash the kernel
      if ciphertext shorter than the block size is passed to it.

      Fortunately, in modern kernels the crypto layer will not crash the
      kernel in this scenario, but nevertheless, it represents a corrupted
      directory, and we should detect it and mark the file system as
      corrupted so that e2fsck can fix this.

      block: make /sys/block/<dev>/queue/discard_max_bytes writeable

      Lots of devices support huge discard sizes these days. Depending
      on how the device handles them internally, huge discards can
      introduce massive latencies (hundreds of msec) on the device side.

      We have a sysfs file, discard_max_bytes, that advertises the max
      hardware supported discard size. Make this writeable, and split
      the settings into a soft and hard limit. This can be set from
      'discard_granularity' and up to the hardware limit.

      Add a new sysfs file, 'discard_max_hw_bytes', that shows the hw
      set limit.

      [media] coda: add macroblock tiling support

      Storing internal frames in macroblock tiled order improves memory
      access patterns by allowing increased burst sizes when transferring
      the uncompressed macroblocks to or from main memory.
      The translation logic only supports a single chroma base address,
      so this is only supported for the chroma interleaved NV12 format.

      Since the rotator used to copy the decoder output into the v4l2
      capture buffers does not seem to support the tiled format correctly,
      only enable it in the encoder for now.

      x86/entry: Fix _TIF_USER_RETURN_NOTIFY check in prepare_exit_to_usermode

      Linus noticed that the early return check was missing
      _TIF_USER_RETURN_NOTIFY.  If the only work flag was
      _TIF_USER_RETURN_NOTIFY, we'd skip user return notifiers.  Fix
      it. (This is the only missing bit.)

      This fixes double faults on a KVM host.  It's the same issue as
      last time, except that this time it's very easy to trigger.
      Apparently no one uses -next as a KVM host.

      ( I'm still not quite sure what it is that KVM does that blows up
        so badly if we miss a user return notifier.  My best guess is that KVM
        lets KERNEL_GS_BASE (i.e. the user's gs base) be negative and fixes
        it up in a user return notifier.  If we actually end up in user mode
        with a negative gs base, we blow up pretty badly. )

      This is already done for one side of the comparison with the expectation
      that the HW counter rolls over at the 16 bit boundary. This is true when

      know the exact wrap-around point for this format just clamp the HW counter
      to the same 16 bits. This should be enough to detect most of the errors

      mac80211: select an AID when creating new mesh STAs

      Instead of using peer link id for AID, generate a new
      AID when creating mesh STAs in the kernel peering manager.
      This enables smaller TIM elements and more closely follows
      the standard, and it also enables mesh to work on drivers
      that require a valid AID when the STA is inserted (ath10k
      firmware has this requirement, for example).

      In the case of userspace-managed stations, we use the AID
      from NL80211_CMD_NEW_STATION.

      mac80211: mesh: separate plid and aid concepts

      According to 802.11-2012 13.3.1, a mesh STA should assign an AID
      upon receipt of a mesh peering open frame rather than using the link
      id of the peer.  Using the peer link id has two potential issues:
      it may not be unique among the peers, and by its nature it is random,
      so the TIM may not compress well.

      In preparation for allocating it properly, use sta->sta.aid, but keep
      the existing behavior of using the plid in the aid we send.

      mac80211: clear local->suspended before calling drv_resume()

      Currently, mac80211 calls drv_resume() on wowlan resume,
      but drops any incoming frame until local->suspended is
      cleared later on.

      This requires the low-level driver to support a new state,
      in which it is expected to fully work (as it was resumed)
      but not passing rx frames yet (as they will be dropped).

      iwlwifi (and probably other drivers as well) has issues
      supporting such mode.

      Since in the wowlan case we already short-circuit
      ieee80211_reconfig, there's nothing that prevents us from
      clearing local->suspend before calling drv_resume(),
      and letting the low-level driver work normally.

      This callback is currently not allowed to sleep, which makes it more
      difficult to implement proper driver methods in mac80211 than it has

      possible for the callback to sleep by doing some asynchronous work
      in cfg80211. This also enables improvements to other drivers, like
      ath6kl, that would like to sleep in this callback.

      While at it, also fix the code to call the driver on the implicit

      mac80211: TDLS: correctly configure SMPS state

      The IEEE802.11-2012 specification is vague regarding SMPS operation during
      TDLS. It does not define a clear way to transition between SMPS states.

      To avoid interop issues, set SMPS to off when TDLS peers are connected.
      Accomplish this by extending the definition of the AUTOMATIC state. If the
      driver forces a state other than OFF, disconnect all TDLS peers.

      While at it, avoid changing the SMPS state of the peer STA. We have no
      way to control it, so try and behave correctly towards it.

      Move the TDLS peer-teardown function to where the rest of the TDLS code
      resides.

      mac80211: enable assoc check for mesh interfaces

      We already set a station to be associated when peering completes, both
      in user space and in the kernel.  Thus we should always have an
      associated sta before sending data frames to that station.

      Failure to check assoc state can cause crashes in the lower-level driver
      due to transmitting unicast data frames before driver sta structures
      (e.g. ampdu state in ath9k) are initialized.  This occurred when
      forwarding in the presence of fixed mesh paths: frames were transmitted
      to stations with whom we hadn't yet completed peering.

      mac80211: mac80211: Check SN for deactivated mpaths

      When processing a PREQ or PREP it's critical to use the incoming SN. If
      that is improperly done routing loops and other types of badness can
      happen. But the code was always processing path messages for deactivated
      paths. This path fixes that so that if we have a valid SN then we use it
      to verify that it is a message we can accept. For reference the relevant
      section of the standard is 13.10.8.4 which doesn't address the deactivated
      path case at all.

      I also included a special case for when our peer reboots or restarts
      networking. This is an important case because without it there can be a
      very long delay before we accept path messages from that peer. It's also a
      simple case and intimately associated with processing messages for
      deactivated paths so I used one patch instead of two.

      mac80211: mesh: don't invalidate SN on discovery failure

      The 2012 spec mentions that path SNs can be invalid when created (see
      section 13.10.8.4 table 13-9) but AFAICT never talks about invalidating
      SNs. Which makes sense: if we have figured out the path to a target at a
      certain SN then we want to remember that fact. Failing to do so can lead
      to routing loops because if we don't have a valid SN then we have no way
      of knowing whether an incoming path message leads to or away from the
      target.

      However currently when discovery fails we zero out mpath->flags which
      clears MESH_PATH_SN_VALID. This patch fixes that so that only the
      discovery relevant flags are cleared.

      mac80211: mesh: add missing case to PERR processing

      When the nexthop is unable to resolve its own nexthop it will send back a
      PERR with a zero target_sn. According to section 13.10.11.4.3 step b in 
the
      2012 standard that perr should be forwarded and the associated mpath->sn
      should be incremented. Neither one of those was happening which is rather
      bad because the originator was not told that packets are black holing.

      mac80211: upgrade BW of TDLS peers when possible

      Define a station chandef, to be used for wider-bw TDLS peers. When both
      peers support the feature, upgrade the channel bandwidth to the maximum
      allowed by both peers and regulatory. Currently widths up to 80MHz are
      supported in the 5GHz band.

      When a TDLS peer connects/disconnects recalculate the channel type of the
      current chanctx.
      Make the chanctx width calculation consider wider-bw TDLS peers and
      similarly fix the max_required_bw calculation for the chanctx min_def.
      Since the sta->bandwidth is calculated only later on, take
      bss_conf.chandef.width as the minimal width for station interface.

      Set the upgraded channel width in the VHT-operation set during TDLS setup.

      mac80211: define TDLS wider BW support bits

      Allow a device to specify support for the TDLS wider-bandwidth feature.
      Indicate this support during TDLS setup in the ext-capab IE and set an
      appropriate station flag when our TDLS peer supports it.
      This feature gives TDLS peers the ability to use a wider channel than
      the base width of the BSS. For instance VHT capable TDLS peers connected
      on a 20MHz channel can extend the channel to 80MHz, if regulatory
      considerations allow it.

      Do not cap the bandwidth of such stations by the current BSS channel width
      in mac80211.

      mac80211: support device/driver PN check for CCMP/GCMP

      When there are multiple RX queues, the PN checks in mac80211 cannot be
      used since packets might be processed out of order on different CPUs.

      Allow the driver to report that the PN has been checked, drivers that
      will use multi-queue RX will have to set this flag.

      For now, the flag is only valid when the frame has been decrypted, in
      theory that restriction doesn't have to be there, but in practice the
      hardware will have decrypted the frame already.

      mac80211: don't store napi struct

      When introducing multiple RX queues, a single NAPI struct will not
      be sufficient. Instead of trying to store multiple, simply change
      the API to have the NAPI struct passed to the RX function. This of
      course means that drivers using rx_irqsafe() cannot use NAPI, but
      that seems a reasonable trade-off, particularly since only two of
      all drivers are currently using it at all.

      While at it, we can now remove the IEEE80211_RX_REORDER_TIMER flag
      again since this code path cannot have a napi struct anyway.

      crypto: poly1305 - Add a SSE2 SIMD variant for x86_64

      Implements an x86_64 assembler driver for the Poly1305 authenticator. This
      single block variant holds the 130-bit integer in 5 32-bit words, but uses
      SSE to do two multiplications/additions in parallel.

      When calling updates with small blocks, the overhead for kernel_fpu_begin/
      kernel_fpu_end() negates the perfmance gain. We therefore use the
      poly1305-generic fallback for small updates.

      For large messages, throughput increases by ~5-10% compared to
      poly1305-generic:

      [media] stk1160: Add frame scaling support

      This commit implements frame decimation for stk1160, which allows
      to support format changes instead of a static frame size.

      The stk1160 supports independent row and column decimation, in two
      different modes:
       * set a number of rows/columns units to skip for each unit sent.
       * set a number of rows/columns units to send for each unit skipped.

      This effectively allows to achieve different frame scaling ratios.

      The unit number can be set to either two row/columns sent/skipped,
      or four row/columns sent/skipped. Since the video format (UYVY)
      has 4-bytes, using a unit number of two row/columns results
      in frame color 'shifting', so set to four row/columns sent/skipped.

      The "function" of the MPP driver was inherited from the GPIO driver, but 
the
      differences between the two hardware blocks makes both the driver and the

      Instead of overloading the "normal" function with various modes this patch
      transposes the pinmux function to represent the three operating modes of 
the
      MPP (digital, analog and current sink). The properties of pin pairing and 
DTEST
      routing is moved to separate properties.

      Merge tag 'gpiod-flags-for-4.3' of git://git.pengutronix.de/git/ukl/linux 
into devel

      The last patch in this series makes the flags parameter for the various
      gpiod_get* functions mandatory and so allows to remove an ugly cpp hack
      introduced in commit 39b2bbe3d715 (gpio: add flags argument to 
gpiod_get*()
      functions) for v3.17-rc1.

      The other nine commits fix the last remaining users of these functions 
that
      don't pass flags yet. (Only etraxfs-uart wasn't fixed; this driver's use 
of the
      gpiod functions needs fixing anyhow.)

      ARM: add basic support for on-demand backtrace of other CPUs

      As we now have generic infrastructure to support backtracing of other
      CPUs in the system on lockups, we can start to implement this for ARM.
      Initially, we add an IPI based implementation, as the GIC code needs
      modification to support the generation of FIQ IPIs, and not all ARM
      platforms have the ability to raise a FIQ in the non-secure world.

      This provides us with a "best efforts" implementation in the absence
      of FIQs.

      nmi: create generic NMI backtrace implementation

      x86s NMI backtrace implementation (for arch_trigger_all_cpu_backtrace())
      is fairly generic in nature - the only architecture specific bits are
      the act of raising the NMI to other CPUs, and reporting the status of
      the NMI handler.

      These are fairly simple to factor out, and produce a generic
      implementation which can be shared between ARM and x86.

      This patch looks for the cleared F01 control register and writes the
      correct value based on interrupt mask computed while scanning the PDT.

      HID: wacom: Properly free inputs if 'wacom_allocate_inputs' fails

      The 'wacom_allocate_inputs' function tries to allocate three input 
devices: one
      each for the pen, touch, and pad. The pointers that are returned by the
      'wacom_allocate_input' calls are temporarily stored to local variables 
where
      they are checked to ensure they're non-null before storing them in the
      'wacom_wac' structure. If an allocation fails,  the 'wacom_free_inputs'
      function is called to reclaim the memory. Unfortunately, 
'wacom_free_inputs' is
      called prior to the pointers being copied, so it is not actually able to 
free
      anything.

      This patch has the calls to 'wacom_allocate_input' store the pointer 
directly
      in the 'wacom_wac' structure where they can be freed. Also, it replaces 
the
      call to 'wacom_free_inputs' with the (more general) 'wacom_clean_inputs' 
and
      removes the no-longer-used function.

      drm/mgag200: remove unneeded variable

      ttm_bo_validate() returns 0 or error. So we can return the value

      acpi-cpufreq: Fix an ACPI perf unregister issue

      As policy->cpu may not be same in acpi_cpufreq_cpu_init() and
      acpi_cpufreq_cpu_exit(). There is a risk that we use different CPU
      to un/register ACPI performance. So 
acpi_processor_unregister_performance()
      may not be able to do the cleanup work. That causes a memory leak. And
      if there will be another acpi_processor_register_performance() call,
      it may also fail thanks to the internal check of pr->performace.

      So add a new struct acpi_cpufreq_data field, acpi_perf_cpu, to fix
      this issue.

       - Based on what we do under such labels

      We follow the first naming convention today and that leads to multiple

      acpi-cpufreq: replace per_cpu with driver_data of policy

      Drivers can store their internal per-policy information in
      policy->driver_data, lets use it.

      we have benefits after this replacing.
      1) memory saving.
      2) policy is shared by several cpus, per_cpu seems not correct. using
      *driver_data* is more reasonable.
      3) fix a memory leak in acpi_cpufreq_cpu_exit. as policy->cpu might
      change during cpu hotplug. So sometimes we cant't free *data*, use
      *driver_data* to fix it.
      4) fix a zero return value of get_cur_freq_on_cpu. Only per_cpu of
      policy->cpu is set to *data*, if we try to get cpufreq on other cpus, we
      get zero instead of correct values. Use *driver_data* to fix it.

      Chained irq handlers usually set up handler data as well. We now have
      a function to set both under irq_desc->lock. Replace the two calls
      with one.

      Search and conversion was done with coccinelle.

      ASoC: rsnd: tidyup data align position

      Sound L/R order of SSI is different from Linux sound data order.
      So current rsnd driver is using DALIGN (= data align) to exchange data
      align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted
      sound volume will be exchanged if user used volume control on DVC.
      Because SSIU which exchanges data align is located after DVC.

        MEM -> SRC -> DVC -> SSI

      This patch exchanges data align SRC if possible

      Renesas sound IP (= SSIU/SRC/CTU/MIX/DVC) have ADINR

      Let's use snd_soc_of_parse_audio_route/prefix.

      regmap: Apply optional delay in multi_reg_write/register_patch

      Add an optional delay_us field in reg_sequence to allow the client to
      specify a delay (in microseconds) to be applied after any given write
      in a sequence of writes.

      We treat a delay in a sequence the same way we treat a page change as
      they are logically similar in that you can coalesce all write before
      a delay (in the same way you can coalesce all writes before a page
      change is needed)

      regmap: Use reg_sequence for multi_reg_write / register_patch

      Separate the functionality using sequences of register writes from the
      functions that take register defaults. This change renames the arguments
      in order to support the extension of reg_sequence to take an optional
      delay to be applied after any given register in a sequence is written.
      This avoids adding an int to all register defaults, which could
      substantially increase memory usage for regmaps with large default tables.

      This also updates all the clients of multi_reg_write/register_patch.

      regulator: 88pm800: Use regulator_nodes/of_match in the descriptor

      This patch is add regulator_nodes/of_match in the regulator
      descriptor for using information from DT instead of specific codes.

      With this patch, driver gets simplified,

        - No need to maintain "struct of_regulator_match" table
          and call of_regulator_match() fn.
        - No need for pm800_regulator_dt_init() fn, as it was only
          used for of_regulator_match().
        - probe() fn got simplified around regulator_config and regulator_desc
          initialization.

      regulator: 88pm800: Update driver to use devm_regulator_register fn

      This patch replaces standard regulator_register with
      devm_regulator_register() fn, as using devm_regulator_register() fn
      simplifies the driver return/exit path.

      As part of this update, patch also cleanups up all unnecessary changes
      which is result of this patch -

        - Remove _remove() fn, as devm_ variant takes care of it.
        - Remove pm800_regulators.regulators[] field, as it was only
          needed during cleanup, so we no longer need this.
          This also saved some amount of memory.

      Input: i8042 - add unmask_kbd_data option

      A big problem with the current i8042 debugging option is that it outputs
      data going to and from the keyboard by default. As a result, many dmesg
      logs uploaded by users will unintentionally contain sensitive information
      such as their password, as such it's probably a good idea not to output
      data coming from the keyboard unless specifically enabled by the user.

      x86/platform/iosf_mbi: Check return value of debugfs_create properly

      The code checks the result of the first debugfs_create call several
      times and fails to check the result of the subsequent calls due to
      missing assigments.

      Add the missing assignments and check only for !res because
      debugfs_create() returns only NULL on error and not an encoded error
      code.

      dmaengine: ioatdma: Ignore IOAT devices under hotplug-capable PCI host 
bridge

      The dmaengine core assumes that async DMA devices will only be removed
      when they not used anymore, or it assumes dma_async_device_unregister()
      will only be called by dma driver exit routines. But this assumption is
      not true for the IOAT driver, which calls dma_async_device_unregister()
      from ioat_remove(). So current IOAT driver doesn't support device
      hot-removal because it may cause system crash to hot-remove an inuse
      IOAT device.

      To support CPU socket hot-removal, all PCI devices, including IOAT
      devices embedded in the socket, will be hot-removed. The idea solution
      is to enhance the dmaengine core and IOAT driver to support hot-removal,
      but that's too hard.

      This patch implements a hack to disable IOAT devices under hotplug-capable
      CPU socket so it won't break socket hot-removal.

      ARM: OMAP2+: Remove legacy booting support for Pandora

      We've been moving all omap2+ based systems to boot in device tree only
      mode for a few years now. Only omap3 has legacy booting support
      remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
      files for booting with device tree.

      This board has support for device tree based booting, and we've been
      printing warnings about the legacy booting being deprecated for a
      few merge cycles now. Let's attempt to remove the legacy booting
      for it.

      The reason for removing the legacy booting support now rather than
      later is we can simply revert this patch if necessary if we run
      into some unexpected issues that are not trivial to fix for the
      device tree based booting.

      pinctrl: sh-pfc: Convert to platform_get_*()

      If the pin function controller (which can be a GPIO controller) is
      instantiated before the interrupt controllers, due to the ordering in
      the DTS, the irq domains for the interrupt controllers referenced by its
      "interrupts-extended" property cannot be found yet:

          irq: no irq domain found for /interrupt-controller@e61c0000 !

      As the sh-pfc driver accesses the platform device's resources directly,
      it cannot find the (optional) IRQ resources, and thinks no interrupts
      are available. This may lead to failures later, when GPIOs are used as
      interupts:

          gpio-keys keyboard: Unable to claim irq 0; error -22
          gpio-keys: probe of keyboard failed with error -22

      To fix this, add support for deferred probing to sh-pfc, by converting
      the driver from direct platform device resource access to using the
      platform_get_resource() and platform_get_irq() helpers.

      Note that while this fixes the root cause worked around by commit
      e4ba0a9bddff3ba5 ("ARM: shmobile: r8a73a4: Move pfc node to work around
      probe ordering bug"), I strongly recommend against reverting the
      workaround now, as this would lead to lots of probe deferrals in drivers
      relying on pinctrl. This may be reconsidered once the DT code starts
      taking into account phandle dependencies during device instantation.

      gpio: rcar: Fine-grained Runtime PM support

      Currently gpio modules are runtime-resumed at probe time. This means the
      gpio module will be active all the time (except during system suspend,
      if not configured as a wake-up source).

      While an R-Car Gen2 gpio module retains pins configured for output at
      the requested level while put in standby mode, gpio registercannot be
      accessed while suspended.  Unfortunately pm_runtime_get_sync() cannot be
      called from all contexts where gpio register access is needed. Hence
      move the Runtime PM handling from probe/remove time to gpio request/free
      time, which is probably the best we can do.

      On r8a7791/koelsch, gpio modules 0, 1, 3, and 4 are now suspended during
      normal use (gpio2 is used for LEDs and regulators, gpio5 for keys, gpio6
      for SD-Card CD & WP, gpio7 for keys and regulators).

      cpufreq: Add cpufreq driver for Tegra124

      Add a new cpufreq driver for Tegra124. Instead of using the PLLX as
      the CPU clocksource, switch immediately to the DFLL. It allows the use
      of higher clock rates, and will automatically scale the CPU voltage as
      well. Besides the CPU clocksource switch, we let the cpufreq-dt driver
      for all the cpufreq operations.

      This driver also relies on the DFLL driver to fill the OPP table for the
      CPU0 device, so that the cpufreq-dt driver knows what frequencies to
      use.

      The DVCO present in the DFLL IP block has a separate reset line,
      exposed via the CAR IP block.  This reset line is asserted upon SoC
      reset.  Unless something (such as the DFLL driver) deasserts this
      line, the DVCO will not oscillate, although reads and writes to the

      clk: tegra: Introduce ability for SoC-specific reset control callbacks

      This patch allows SoC-specific CAR initialization routines to register
      their own reset_assert and reset_deassert callbacks with the common Tegra
      CAR code. If defined, the common code will call these callbacks when a
      reset control with number >= num_periph_banks * 32 is attempted to be 
asserted
      or deasserted respectively. Numbers greater than or equal to 
num_periph_banks * 32
      are used to avoid clashes with low numbers that are automatically mapped 
to
      standard CAR reset lines.

      Each SoC with these special resets should specify the defined reset 
control
      numbers in a device tree header file.

      clk: tegra: Add functions for parsing CVB tables

      Tegra CVB tables encode the relationship between operating voltage
      and optimal frequency as a function of the so-called speedo value.
      The speedo value is written to the on-chip fuses at the factory,
      which allows the voltage-frequency operating points to be calculated
      on an per-chip basis.

      Add utility functions to parse the Tegra-specific tables and export the
      voltage-frequency pairs to the generic OPP framework for other drivers
      to use.

      clk: tegra: Add closed loop support for the DFLL

      With closed loop support, the clock rate of the DFLL can be adjusted.

      The oscillator itself in the DFLL is a free-running oscillator whose
      rate is directly determined the supply voltage. However, the DFLL
      module contains logic to compare the DFLL output rate to a fixed
      reference clock (51 MHz) and make a decision to either lower or raise
      the DFLL supply voltage. The DFLL module can then autonomously change
      the supply voltage by communicating with an off-chip PMIC via either I2C
      or PWM signals. This driver currently supports only I2C.

      Merge branch 'protodown'

      Anuradha Karuppiah says:

      ====================
      net: Introduce protodown flag.

      User space daemons can detect errors in the network that need to be
      notified to the switch device drivers.

      Drivers can react to this error state by doing a phy-down on the
      switch-port which would result in a carrier-off locally and on the 
directly
      connected switch. Doing that would prevent loops and black-holes in the
      network.

      One such use case is the multi-chassis LAG application -

      1. The MLAG application runs on peer switches (say Switch0 and Switch1)
         synchronizing states, forwarding entries etc. between the two
         switches over the peer-link (this is a link directly connecting the
         two switches).
      2. An MLAG election process designates one of the switches as a primary
         (for e.g. Switch0 is primary and Switch1 is secondary).
      3. The peer link plays a critical role in allowing Switch0-Switch1 to
         function as a single LAG partner to the downstream dual-connected
         servers. When the peer-link between the switches goes down we have a
         split-brain situation. Switch0 and Switch1 are no longer in sync and
         are acting independently. This can result in traffic loops and
         traffic black-holing in the network.
      4. To prevent these problems the MLAG application on the secondary
         switch phy-downs the MLAG ports on detecting the peer-link down.
         This will be seen as a carrier down on servers that are
         dual-connected to Switch0 and Switch1.
      5. Specifically a dual-connected server will see a carrier-down on the
         port connected to the MLAG secondary, Switch1, and will stop using
         that port for traffic TX. So traffic black holing is prevented.

      v6 to v7:
         Removed some unnecessary code in response to review comments.

      v5 to v6:
         Replaced proto_flags with a simple proto_down boolean attribute in
         response to Dave's comments.

      v4 to v5:
         Changed the ip link display format for protodown to match the set as
         recommended by Stephen.

      v3 to v4:
         I have moved protodown out of IFF_XXX and introduced a separate
         proto_flags field with IF_PROTOF_DOWN bit being used by apps to notify
         switch port errors. This is in response to Stephen's comments that
         adding a new IFF_XXX may break user space.

         I have used rocker as the sample switch driver. And to test this
         functionality I used the qemu-rocker patch that Scott sent out in
         response to the v3 posting (needed to set link up/down when phy is
         enabled/disabled).

      v1 to v2:
         Based on Dave's suggestion I have moved out aggregating of error bits
         across applications to a user space framework. This patch now simply
         notifies an aggregated error bit to drivers enabling them to handle
         the error gracefully.

      powerpc/powernv: Add poweroff (EPOW, DPO) events support for PowerNV 
platform

      This patch adds support for OPAL EPOW (Environmental and Power Warnings)
      and DPO (Delayed Power Off) events for the PowerNV platform. These events
      are generated on FSP (Flexible Service Processor) based systems. EPOW
      events are generated due to various critical system conditions that
      require system shutdown. A few examples of these conditions are high
      ambient temperature or system running on UPS power with low UPS battery.
      DPO event is generated in response to admin initiated system shutdown
      request. Upon receipt of EPOW and DPO events the host kernel invokes
      orderly_poweroff() for performing graceful system shutdown.

      Intel Wired LAN Driver Updates 2015-07-14

      This series contains updates to i40e and i40evf only.

      Joe Stringer and Jesse Gross add a ndo_features_check function to ensure
      that the i40e driver does not try to offload packets that exceed 80 bytes
      in length.

      Anjali adds additional stats to track flow director ATR and SB current
      state and flow director flush count which will help the need for verbose
      debug logs with respect to flow director.  Also refines an error message
      to avoid confusion, so that it indicates what may have really happened
      when the init_shared_code() call possibly fails.

      Pawel adds new fields to the capabilities structures to handle Flex-10
      device/function capabilities which is needed to support Flex-10 configs.

      Jesse improves the transmit performance by added a prefetch for the
      next transmit descriptor to be used when we know there are more coming.

      Mitch modifies i40evf driver to handle/allow an abundance of vectors.
      Currently the driver only maps transmit and receive queues to a single
      MSI-X vector per queue if there are exactly enough vectors for this, but
      if we have too many vectors, it will fail and allocate queues to vectors
      in a suboptimal manner.  So change the condition check to allow for an
      excess number of vectors and won't use the extras.  Also update the
      driver to just return success if the user attempts to set a port VLAN on
      a VF that already has the same port VLAN configured, instead of going
      through unnecessary filter removals & adds.  Fix the MAC filters for VFs,
      which were being programmed with 0 for the VLAN value when there was no
      VLAN assigned.  Instead, we must use -1 to indicate that no VLAN is in
      use.  Fix the VF disable code, which was not properly cleaning up the VF
      and would leave the VF in an indeterminate state, so fix this by
      notifying the VF and then call the normal VF reset routine.  Fix the
      logic in the driver so that MAC filters are added and removed correctly
      and added a check for the driver's hardware MAC address so that this
      filter does not get removed incorrectly.

      Carolyn removes incorrect #ifdef's which should not have been added in
      the first place and with the #ifdef's removed, make the necessary
      changes in the driver to resolve compile errors.

      Greg updates the admin queue command header defines.

      gianfar: Add Rx S/G

      This patch-set introduces scatter/gather support
      on the Rx side, addressing Rx path performance
      issues in the driver.
      Thanks.

      As an example, two boards connected back-to-back
      were used to measure the throughput, running the
      same kernel 4.1, before and after applying these
      patches.
      The netperf UDP_STREAM results below show that the
      bottleneck lies on the Rx side BEFORE applying the
      patches, and that the Rx throughput is even lower
      with a larger MTU.  AFTER applying the patches the
      Rx bottleneck is gone (Rx throughput matches the
      Tx one) and the RX throughput is not influenced by
      MTU size any longer (as expected).

      gianfar: Add paged allocation and Rx S/G

      The eTSEC h/w is capable of scatter/gather on the receive side
      too if MAXFRM > MRBLR, when the allowed maximum Rx frame size
      is set to be greater than the maximum Rx buffer size (MRBLR).
      It's about time the driver makes use of this h/w capability,
      by supporting fixed buffer sizes and Rx S/G.

      The buffer size given to eTSEC for reception is fixed to
      1536B (must be multiple of 64), which is the same default
      buffer size as before, used to accommodate standard MTU
      (1500B) size frames.  As before, eTSEC can receive frames of
      up to 9600B.  Individual Rx buffers are mapped to page halves
      (page size for eTSEC systems is 4KB).  The skb is built around
      the first buffer of a frame (using build_skb()).  In case the
      frame spans multiple buffers, the trailing buffers are added
      as Rx fragments to the skb.  The last buffer in frame is marked
      by the L status flag.  A mechanism is in place to reuse the pages
      owned by the driver (for Rx) for subsequent receptions.

      Supporting fixed size buffers allows the implementation of Rx S/G,
      which in turn removes the memory pressure issues the driver had
      before when MTU was set for jumbo frame reception.
      Also, in most cases, the Rx path becomes faster due to Rx page
      reusal, since the overhead of allocating new rx buffers is removed
      from the fast path.

      gianfar: Fix and cleanup rxbd status handling

      There are several (long standing) problems about how the status
      field of the rx buffer descriptor (rxbd) is currently handled on
      the error path:
      - too many unnecessary 16bit reads of the two halves of the rxbd
      status field (32bit), also resulting in overuse of endianness
      convesion macros;
      - "bdp->status = RXBD_LARGE" makes no sense, since the "large"
      flag is read only (only eTSEC can write it), and trying to clear
      the other status bits is also error prone in this context
      (most of the rx status bits are read only anyway).

      This is fixed with a single 32bit read of the "status" field,
      and then the appropriate 16bit shifting is applied to access
      the various status bits or the rx frame length. Also corrected
      the use of the RXBD_LARGE flag.

      Additional fix:
      "rx_over_errors" stat is incremented instead of "rx_crc_errors"
      in case of RXBD_OVERRUN occurrence.

      gianfar: Bundle Rx allocation, cleanup

      Use a more common consumer/ producer index design to improve
      rx buffer allocation.  Instead of allocating a single new buffer
      (skb) on each iteration, bundle the allocation of several rx
      buffers at a time.  This also opens the path for further memory
      optimizations.

      Remove useless check of rxq->rfbptr, since this patch touches
      rx pause frame handling code as well.  rxq->rfbptr is always
      initialized as part of Rx BD ring init.

      gpio: altera: use of_mm_gpiochip_remove() to fix memory leak

      This driver calls of_mm_gpiochip_add() to add a memory mapped gpio
      chip.  So, of_mm_gpiochip_remove() should be used when removing it.

      The direct call of gpiochip_remove() misses unmapping the register
      and freeing the label.

      dt-bindings: brcmstb-gpio: document properties for wakeup

      Some brcmstb GPIO controllers can be used to wake from suspend, so use
      the de facto standard property 'wakeup-source' to mark the nodes of
      controllers with that capability.

      Also document interrupts-extended, which will be used for wakeup
      handling because the interrupt parent for the wake IRQ is different
      from the regular IRQ.

      While we're at it, a few more fixes: We don't actually use the
      "interrupt-names" property, so remove it from the listed optional
      properties and from the examples.  And since we're modifying the
      examples, also follow Brian's suggestions to:
      - change #gpio-cells, #interrupt-cells, and brcm,gpio-bank-widths from
        hex to dec
      - use phandles

      rcu: Limit rcu_state::levelcnt[] to RCU_NUM_LVLS items

      Variable rcu_num_lvls is limited by RCU_NUM_LVLS macro.
      In turn, rcu_state::levelcnt[] array is never accessed
      beyond rcu_num_lvls. Thus, rcu_state::levelcnt[] is safe
      to limit to RCU_NUM_LVLS items.

      Since rcu_num_lvls could be changed during boot (as result
      of rcutree.rcu_fanout_leaf kernel parameter update) one might
      assume a new value could overflow the value of RCU_NUM_LVLS.
      However, that is not the case, since leaf-level fanout is only
      permitted to increase, resulting in rcu_num_lvls possibly to
      decrease.

      Currently a condition when RCU tree is unable to accommodate

      rcu: Change return type to bool

      Type-checking coccinelle spatches are being used to locate type mismatches
      between function signatures and return values in this case this produced:
      ./kernel/rcu/srcu.c:271 WARNING: return of wrong type
              int != unsigned long,

      srcu_readers_active() returns an int that is the sum of per_cpu unsigned
      long but the only user is cleanup_srcu_struct() which is using it as a
      boolean (condition) to see if there is any readers rather than actually
      using the approximate number of readers. The theoretically possible
      unsigned long overflow case does not need to be handled explicitly - if
      we had 4G++ readers then something else went wrong a long time ago.

      proposal: change the return type to boolean. The function name is left
                unchanged as it fits the naming expectation for a boolean.

      patch was compile tested for x86_64_defconfig (implies CONFIG_SRCU=y)

      DEBUG_LOCK_ALLOC=y is not a production setting, but it is
      not very unusual either. Many developers routinely

      Apart from being selected by hand, it is also auto-selected by
      PROVE_LOCKING "Lock debugging: prove locking correctness" and
      LOCK_STAT "Lock usage statistics" config options.
      LOCK STAT is necessary for "perf lock" to work.

      I wouldn't spend too much time optimizing it, but this particular
      function has a very large cost in code size: when it is deinlined,
      code size decreases by 830,000 bytes:

      Jonathan writes:

      First round of new drivers, cleanups and functionality for IIO in the 4.3 
cycle.

      Core and tools new stuff
      * Allow explicit flush of hardware fifo by using an non blocking read.
        This is needed to support some of the Android requirements for HW fifo
        devices - also makes sense generally and clarifies a corner of the ABI.
      * Add some missing modifier names.  Mostly these exist for weird and
        wonderful event types, but should still be present in the name array.
      * Update iio_event_monitor to cope with new channel types.
      * generic_buffer gains support for single byte scan elements (no idea
        how this never got implemented before!)

      New device support
      * ROHM rpr0521 light and proximity sensor driver.
      * bmc150 gains bmc156 support.
      * ms5611 gains ms5607 temperature and pressure sensor support.

      Driver functionality
      * inv-mpu - add scale_available attributes to aid userspace in
        configuring these devices.
      * isl29125 - add scale_available attributes.
      * stk8ba50 - sampling frequency control, triggered buffer support.
      * stk8312 - sampling frequency control, triggered buffer support.
      * cc10001 - ensure ADC powered up at probe time if shared by non linux
        running CPUs.
      * bmc150-magn - decouple the buffer and trigger allowing other triggers
        to be used to drive this device's sampling.
      Documentation
      * Add some previously missed *scale_available attributes to the ABI docs.

      Cleanups
      * Clarify some crazy naming in iio_triggered_buffer_setup that seems to
        have somehow ended up backwards (dates back a long way).  Avoid the top
        half and bottom half naming entirely given we are how dealing with a
        handler and a thread in all cases.
      * Tools cleanup including coding style, variable naming improvements, also
        a new sanity check on a full event having been read.
      * stk8ba50 - replace the scale table with a struct for clarity. Also 
suspend
        the sensor if an error occurs in init.
      * hid-sensor-prox - drop uneeded line break.
      * mma9551 - use size in words for word read / write avoiding accidental
        sending of an odd number of bytes.
      * mma9553 - fix code alignment and document the use of a mutex.
      * light/Kconfig - typo fix in commment.
      * cm3323 - don't eat an error value, replace an unneeded local variable 
with
        a generic local variable with the same use, add some blank lines for 
clarity.
      * pressure/Kconfig - typo in Measurement Specialties name.
      * bmc150-accel - actually use a mask definition rather than repeating the
        value inline, code style cleanup.
      * adc/Kconfig - general help description cleanup.
      * ssp_sensors - drop redundant spi driver bus initialization (done in the
        spi core)
      * tmp006 - use genmask rather than hand generated masks.
      * ms5611 - drop IIO_CHAN_INFO_SCALE as this driver provides a processed
        output and as such the read only scale adds nothing useful.
      * kxcjk-1013, adf4350, dummy - drop unwanted blank lines.
      * Drop all owner assignments from i2c_drivers and this is done in the
        i2c core.

      seccomp: add ptrace options for suspend/resume

      This patch is the first step in enabling checkpoint/restore of processes
      with seccomp enabled.

      One of the things CRIU does while dumping tasks is inject code into them
      via ptrace to collect information that is only available to the process
      itself. However, if we are in a seccomp mode where these processes are
      prohibited from making these syscalls, then what CRIU does kills the task.

      This patch adds a new ptrace option, PTRACE_O_SUSPEND_SECCOMP, that 
enables
      a task from the init user namespace which has CAP_SYS_ADMIN and no seccomp
      filters to disable (and re-enable) seccomp filters for another task so 
that
      they can be successfully dumped (and restored). We restrict the set of
      processes that can disable seccomp through ptrace because although today
      ptrace can be used to bypass seccomp, there is some discussion of closing
      this loophole in the future and we would like this patch to not depend on
      that behavior and be future proofed for when it is removed.

      Note that seccomp can be suspended before any filters are actually
      installed; this behavior is useful on criu restore, so that we can suspend
      seccomp, restore the filters, unmap our restore code from the restored
      process' address space, and then resume the task by detaching and have the
      filters resumed as well.

      v2 changes:

      * require that the tracer have no seccomp filters installed
      * drop TIF_NOTSC manipulation from the patch
      * change from ptrace command to a ptrace option and use this ptrace option
        as the flag to check. This means that as soon as the tracer
        detaches/dies, seccomp is re-enabled and as a corrollary that one can 
not
        disable seccomp across PTRACE_ATTACHs.

      v3 changes:

      * get rid of various #ifdefs everywhere
      * report more sensible errors when PTRACE_O_SUSPEND_SECCOMP is incorrectly
        used

      v4 changes:

      * get rid of may_suspend_seccomp() in favor of a capable() check in ptrace
        directly

      v5 changes:

      * check that seccomp is not enabled (or suspended) on the tracer

      netfilter: xtables: don't save/restore jumpstack offset

      In most cases there is no reentrancy into ip/ip6tables.

      For skbs sent by REJECT or SYNPROXY targets, there is one level
      of reentrancy, but its not relevant as those targets issue an absolute
      verdict, i.e. the jumpstack can be clobbered since its not used
      after the target issues absolute verdict (ACCEPT, DROP, STOLEN, etc).

      So the only special case where it is relevant is the TEE target, which
      returns XT_CONTINUE.

      This patch changes ip(6)_do_table to always use the jump stack starting
      from 0.

      When we detect we're operating on an skb sent via TEE (percpu
      nf_skb_duplicated is 1) we switch to an alternate stack to leave
      the original one alone.

      Since there is no TEE support for arptables, it doesn't need to
      test if tee is active.

      The jump stack overflow tests are no longer needed as well --
      since ->stacksize is the largest call depth we cannot exceed it.

      A much better alternative to the external jumpstack would be to just
      declare a jumps[32] stack on the local stack frame, but that would mean
      we'd have to reject iptables rulesets that used to work before.

      Another alternative would be to start rejecting rulesets with a larger
      call depth, e.g. 1000 -- in this case it would be feasible to allocate the
      entire stack in the percpu area which would avoid one dereference.

      This prepares for a TEE like expression in nftables.
      We want to ensure only one duplicate is sent, so both will

      The other use case is detection of recursive call to xtables, but since
      we don't want dependency from nft to xtables core its put into core.c
      instead of the x_tables core.

      netfilter: xtables: compute exact size needed for jumpstack

      The {arp,ip,ip6tables} jump stack is currently sized based
      on the number of user chains.

      However, its rather unlikely that every user defined chain jumps to the
      next, so lets use the existing loop detection logic to also track the
      chain depths.

      The stacksize is then set to the largest chain depth seen.

      netfilter: Per network namespace netfilter hooks.

      - Add a new set of functions for registering and unregistering per
        network namespace hooks.

      - Modify the old global namespace hook functions to use the per
        network namespace hooks in their implementation, so their remains a
        single list that needs to be walked for any hook (this is important
        for keeping the hook priority working and for keeping the code
        walking the hooks simple).

      - Only allow registering the per netdevice hooks in the network
        namespace where the network device lives.

      - Dynamically allocate the structures in the per network namespace
        hook list in nf_register_net_hook, and unregister them in
        nf_unregister_net_hook.

        Dynamic allocate is required somewhere as the number of network
        namespaces are not fixed so we might as well allocate them in the
        registration function.

        The chain of registered hooks on any list is expected to be small so
        the cost of walking that list to find the entry we are unregistering
        should also be small.

        Performing the management of the dynamically allocated list entries
        in the registration and unregistration functions keeps the complexity
        from spreading.

      drm/i915: Invert fastboot check

      Fastboot should only downgrade a modeset if we have a match, not be
      used to upgrade to a full modeset. Otherwise we can only use it in a
      very restricted way: Initial modeset when the request mode is the
      preferred one of the panel and there's still a pfit active. And that
      only works because our mode_from_pipe_config fills in the wrong mode
      (it takes the adjusted mode, not the requested one).

      But we want fast modesets everywhere even after boot-up (especially
      for testing, but not only there). Hence we need to be able to make any
      modeset a fast one, which means we need to invert the logic and
      optionally downgrade a modeset.

      Note that this needs ->connector_changed split out from ->mode_changed
      otherwise it's not going to work (because we might loose a modeset
      because connectors changed but otherwise the config matches). As soon
      as that's merged we can drop the i915.fastboot check from this code.

      Also make sure that we don't accidentally clear any_ms and that we add
      the planes for any kind of modeset.

      Finally rename fastboot to fastset (yeah it's a silly name) since this
      really isn't about booting all that much.

      drm/i915: Clarify logic for initial modeset

      Currently we both set mode->private_flags to some value and also use
      the pipe_config quirk. But since the pipe_config quirk isn't tied to
      the lifetime of the mode object we need to check both.

      Simplify this by only using mode.private_flags and stop using the
      INHERITED_MODE quirk. Also for clarity add an explicit #define for
      that driver priavete mode flag.

      we don't have problems with stale configuration data for the global

      Backmerge fixes since it's getting out of hand again with the massive
      split due to atomic between -next and 4.2-rc. All the bugfixes in
      4.2-rc are addressed already (by converting more towards atomic
      instead of minimal duct-tape) so just always pick the version in next
      for the conflicts in modeset code.

      All the other conflicts are just adjacent lines changed.

      staging: vme_user: allow large read()/write()

      This changes large master transfers to do shorter read/write rather than
      return -EINVAL. User space will now be able to optimistically request a
      large transfer and get at least some data.

      This also removes comments suggesting on how to implement large
      transfers. Current vme_master_* read and write implementations use CPU
      copies that don't produce burst PCI accesses and subsequently no block
      transfer on VME bus. In the end overall performance is quiet low and it
      can't be fixed by doing direct copy to user space. Much easier solution
      would be to just reuse kernel buffer.

      staging: ion: debugfs to shrink pool

      This patch enables debugfs file /sys/kernel/debug/ion/heaps/system_shrink
      to shrink pool and get pool size. This technically enables debugfs
      shrinking for all heaps, not just the system heap although the system heap
      is the only one with a shrinker right now. It is already implemented
      but not complete. This patch completes and enables it.

      Reading the file returns pool size
      in page unit and writing the number of pages shrinks pool.
      It flushes all pages to write zero at the file.

      staging: ion: shrink page-pool by page unit

      This patch shrink page-pool by page unit.

      The system shrinker calls ion_heap_shrink_count() to get nr_to_scan,
      and pass it to ion_heap_shrink_scan().
      The problem is the return value of ion_heap_shrink_count() is the number
      of pages but ion_system_heap_shrink(), which is called by
      ion_heap_shrink_scan(), gets the number of chunk.

      The main root of this is that ion_page_pool_shrink() returns page count
      via ion_page_pool_total() if it have to check pool size. But it frees
      chunks of pages if it have to free pools.

      This patch first fix ion_page_pool_shrink() to count only pages,
      not chunks. And then ion_system_heap_shrink() to work on pages.

      Some quirks search for a HyperTransport capability and use a hard-coded 
TTL
      value of 48 to avoid an infinite loop.

      Move the definition of PCI_FIND_CAP_TTL to pci.h and use it instead of the
      hard-coded TTL values.

      Note that the 6 in the third argument of memset appears to represent
      an ethernet address size (ETH_ALEN).

      ARM: dts: ventana: add UHS-I support for Ventana boards

      UHS-I support is available on Ventana boards with micro-SD sockets 
depending
      on the board revision. To support this pinctl states for 100Mhz and 200MHz
      must be added as well as pinmux of the VSELECT signal. In order to support
      UHS-I the I/O rail of the 4-bit data bus must be switchable between 1.8V
      and 3.3V.

      By adding the no-1-8-v property, which disables UHS-I support, we allow 
the
      bootloader to be in charge of selecting which boards have this capability
      by removing that property if the board model/revision implement the 
support.

      Additionally we will remove NANDF_CS1 here from the nand pinmux group as 
the
      second chip-select is not used on any ventana boards and this is the pad
      that is used for SD3_VELECT.

      staging: unisys: fix random hangs with network stress in visornic

      We learned that it was possible for the core networking code to call
      visornic_xmit() within ISR context, resulting in the need for us to
      use spin_lock_irqsave() / spin_lock_irqrestore() to lock accesses to our
      virtual device channels.

      Without the correct locking added in this patch, random hangs would occur
      on typical kernels while stressing the netork.  When using a kernel with
      CONFIG_DEBUG_SPINLOCK=y, a stackdump would occur at the time of the hang
      reporting:

          BUG: spinlock recursion on CPU#0, vnic_incoming/<pid>

      (see below for more details)

      We considered the possibility of adding a protocol between a visordriver
      and visorbus where the visordriver could specify which type of locking it
      required for its virtual device channels (essentially indicating whether
      or not it was possible for the channel to be accessed in ISR context), but
      decided this extra complexity was NOT needed, and that channel queues
      should always be accessed with the most-stringent locking.  So that is
      what is implemented in this commit.

      Below is an example stackdump illustrating the spinlock recursion that is
      fixed by this commit.  Note that we are first in virtnic_rx() writing to
      the device channel when an APIC timer interrupt occurs.  Within the core
      networking code, net_rx_action() calls process_backlog(), which eventually
      lands up back up in virtnic_xmit() in the code attempting to also write to
      the device channel.

      staging: unisys: fix random memory corruption in visorchannel_write()

      visorchannel_write() and it's user visorbus_write_channel() are
      exported, so all visorbus function drivers (i.e., drivers that call
      visorbus_register_visor_driver()) are potentially affected by the bug.

      Because of pointer-arithmetic rules, the address being written to in the
      affected code was actually at byte offset:

          sizeof(struct channel_header) * offset

      instead of just <offset> bytes as intended.

      The bug could cause some very difficult-to-diagnose symptoms.  The
      particular problem that led me on this chase was a kernel fault that
      would occur during 'insmod visornic' after a previous 'rmmod visornic',
      where we would fault during netdev_register_kobject() within
      pm_runtime_set_memalloc_noio() while traversing a device list, which
      occurred because dev->parent for the visorbus device had become
      corrupted.

      staging: unisys: visornic: prevent erroneous kfree of devdata pointer

      A struct visornic_devdata for each visornic device is actually allocated 
as
      part of alloc_etherdev(), here in visornic_probe():

          netdev = alloc_etherdev(sizeof(struct visornic_devdata));

      But code in devdata_release() was treating devdata as a pointer that 
needed
      to be kfree()d!  This was causing all sorts of weird behavior after doing
      an rmmod of visornic, both because free_netdev() was actually freeing the
      memory used for devdata, and because devdata wasn't pointing to
      dynamically-allocated memory in the first place.

      The kfree(devdata) and the kref that tracked devdata's usage have been
      appropriately deleted.

      staging: unisys: visornic: correctly clean up device on removal

      visornic_remove() is called to logically detach the visornic driver from a
      visorbus-supplied device, which can happen either just prior to a
      visorbus-supplied device disappearing, or as a result of an rmmod of
      visornic.  Prior to this patch, logic was missing to properly clean up for
      this removal, which was fixed via the following changes:

      * A going_away flag is now used to interlock between device destruction 
and
        workqueue operations, protected by priv_lock.  I.e., setting
        going_away=true under lock guarantees that no new work items can get
        queued to the work queues.  going_away=true also short-circuits other
        operations to enable device destruction to proceed.

      * Missing clean-up operations for the workqueues, netdev, debugfs entries,
        and the worker thread were added.

      * Memory referenced from the visornic private devdata struct is now freed
        as part of devdata destruction.

      staging: unisys: visornic: correct obvious double-allocation of workqueues

      Looks like an errant patch fitting caused us to redundantly allocate the
      workqueues at both the beginning and end of visornic_init().  This was
      corrected by removing the allocations at the beginning.

      staging: unisys: add error messages to visornic

      Add error message to genuine rare error paths, and debug messages
      to enable relatively non-verbose tracing of code paths

      You can enable debug messages by including this on the kernel command 
line:

          visornic.dyndbg=+p

      or by this from the command line:

          echo "module visornic +p" > <debugfs>/dynamic_debug/control

      Refer to Documentation/dynamic-debug-howto.txt for more details.

      In addition to the new debug and error messages, a message like the
      following will be logged every time a visornic device is probed, which
      will enable you to map back-and-forth between visorbus device names
      (e.g., "vbus2:dev0") and netdev names (e.g., "eth0"):

          visornic vbus2:dev0: visornic_probe success netdev=eth0

      With this patch and visornic debugging enabled, you should expect to see
      messages like the following in the most-common scenarios:

      * driver loaded:

            visornic_init

      * device probed:

            visornic vbus2:dev0: visornic_probe
            visor_thread_start
            visor_thread_start success

      * network interface configured (ifconfig):

            net eth0: visornic_open
            net eth0: visornic_enable_with_timeout
            net eth0: visornic_enable_with_timeout success
            net eth0: visornic_open success

      staging: unisys: neglect to NULL rcvbuf pointer

      Neglect to NULL rcvbuf pointer array could result in faults later

      This problem would exhibit itself as a fault when when attempting to stop
      any visornic device (i.e., in visornic_disable_with_timeout() or
      visornic_serverdown_complete()) that had never been started (i.e., for
      which init_rcv_bufs() had never been called).  Because the array of rcvbuf
      was never cleared to NULLs, we would mistakenly attempt to call 
kfree_skb()
      on garbage memory.

      Prevent faults in visornic_pause, visornic_resume(), and visornic_remove()

      Prior to this patch, any call to visornic_pause(), visornic_resume(), or
      visornic_remove() would fault, due to dev_set_drvdata() never having been
      called to stash our struct visornic_devdata * into the device's drvdata.
      I.e., all calls to dev_get_drvdata() were returning NULL, meaning a fault
      was soon to follow.

      staging: unisys: visornic: correct visornic_pause

      Correct visornic_pause() to indicate completion asynchronously rather
      than in-line

      Previously, visornic_pause() (called to stop the device due to IOVM 
service
      partition recovery) was calling the passed complete_func() in-line, rather
      than delaying the calling until after the device had actually been 
stopped.

      The behavior has been corrected so that the calling of the complete_func()
      is now delayed until after the stopping of the device has been completed 
in
      visornic_serverdown_complete(), which runs asynchronously via the 
workqueue
      visornic_serverdown_workqueue.

      staging: unisys: prevent faults processing messages

      Prevent faults processing messages for devices that no driver has yet
      registered to handle.

      Previously, code of the form:

          drv = to_visor_driver(dev->device.driver);
          if (!drv)
              goto away;

      was not having the desired intent, because to_visor_driver() was
      essentially returning garbage if its argument was NULL.  The only existing
      case of this is in initiate_chipset_device_pause_resume(), which is called
      during IOVM service partition recovery.  We were thus faulting when IOVM
      service partition recovery was initiated on a bus that had at least one
      device for which no function driver had registered
      (visorbus_register_visor_driver).

      staging: unisys: respond to msgs post device_create

      Fix problem that prevents us from responding to any device message after
      device_create.

      By neglecting to NULL out pending_msg_hdr after the device_create 
response,
      we were effectively preventing any subsequent messages to the device from
      working, because device_epilog() will correctly bail out early if it sees
      that pending_msg_hdr is still set non-NULL, as that is an indicator to 
mean
      that an unanswered message is still outstanding.

      This problem was discovered as part of testing IOVM service partition
      recovery, because device_epilog() was in fact bailing out when it was
      called from my_device_changestate(), which of course prevented us from
      transitioning the device to the paused state.  However, the incorrect
      behavior would occur for ANY subsequent command directed at the device,
      not just for changestate.

      driver for PBLE resource.

      The i40e_remove_pd_bp() is also modified to not free pre-allocated pages 
and
      free only ones which were allocated in i40e_add_pd_table_entry().

      i40evf: don't delete all the filters

      Due to an inverted conditional, the driver was marking all of its MAC
      filters for deletion every time set_rx_mode was called. Depending upon
      the timing of the calls to set_rx_mode and the processing of the admin
      queue, the driver would (accidentally) end up with a varying number of
      functional filters.

      Correct this logic so that MAC filters are added and removed correctly.
      Add a check for the driver's "hardware" MAC address so that this filter
      doesn't get removed incorrectly.

      there was no VLAN assigned. This is incorrect and actually assigns the
      VF to VLAN 0. Instead, we must use -1 to indicate that no VLAN is in
      use. This change programs the filters correctly and gets rid of a bogus
      error message when setting a port VLAN on an active VF.

      i40e: Remove incorrect #ifdef's

      This patch removes some #ifdef's that should not be there. They
      were stopping code that is needed from being compiled in.

      With these #ifdef's removed, changes are needed in the driver
      to fix some compile errors: adding missing parameters to
      the definition of ndo_bridge_setlink and a ndo_dflt_brige_getlink call.

      i40evf: Allow for an abundance of vectors

      The driver currently only maps TX and RX queues to a single MSI-X vector
      per queue pair if there are exactly enough vectors for this.
      Unfortunately, if we have too many vectors it will fail and allocate
      queues to vectors in a suboptimal manner. Change the condition check to
      allow for excess vectors. In this case, the extras just won't be used.

      staging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN

      If the "comedi" module has been loaded with the
      "comedi_num_legacy_minors" module parameter set to a non-zero value,
      some reserved comedi devices get created.  These can be attached to a
      low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
      which checks for the `CAP_SYS_ADMIN` capability.  Of course, the comedi
      device needs to be opened before the ioctl command can be sent.  If the
      comedi device is unattached, `comedi_open()` currently requires the
      `CAP_NET_ADMIN` capability.  It makes more sense to just require the
      `CAP_SYS_ADMIN` capability here, so change it.

      For the curious, commit a8f80e8ff94e ("Networking: use CAP_NET_ADMIN
      when deciding to call request_module") changed this capability from
      `CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
      relevant here.  The original `CAP_SYS_MODULE` capability was due to the
      function having some code to request a module using a "char-major-%i-%i"
      alias, but that was never compiled in and was removed by commit
      f30f2c2d417b ("staging: comedi: remove check for CONFIG_KMOD").

      staging: comedi: cb_pcimdas: add external analog output ranges

      The analog output range is not programmable, but the ranges for each of
      the two analog output channels are settable via jumpers.  These jumper
      settings are not readable by the driver.  The driver
      provides a range table containing all the possible internal ranges
      (+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
      application (although any range selected by the application that differs
      from the jumper settings will not produce the expected voltage output).

      The range table does not cover all possible ranges of the analog output
      channels.  The jumpers also allow an external reference voltage between
      0 and 10V to be used as bipolar or unipolar output range.  Add a couple
      more ranges to the end of the range table to define these two external
      ranges.

      xtensa: fix threadptr reload on return to userspace

      Userspace return code may skip restoring THREADPTR register if there are
      no registers that need to be zeroed. This leads to spurious failures in
      libc NPTL tests.

      Always restore THREADPTR on return to userspace.

      PCI: Add pcie_downstream_port() (true for Root and Switch Downstream 
Ports)

      As used in the PCIe spec, "Downstream Port" includes both Root Ports and
      Switch Downstream Ports.  We sometimes checked for PCI_EXP_TYPE_DOWNSTREAM
      when we should have checked for PCI_EXP_TYPE_ROOT_PORT or
      PCI_EXP_TYPE_DOWNSTREAM.

      For a Root Port without a slot, the effect of this was that using
      pcie_capability_read_word() to read PCI_EXP_SLTSTA returned zero instead 
of
      showing the Presence Detect State bit hardwired to one as the PCIe Spec,
      r3.0, sec 7.8, requires.  (This read is completed in software because
      previous PCIe spec versions didn't require PCI_EXP_SLTSTA to exist at 
all.)

      Nothing in the kernel currently depends on this (pciehp only reads
      PCI_EXP_SLTSTA on ports with slots), so this is a cleanup and not a
      functional change.

      Add a pcie_downstream_port() helper function and use it.

      cgroup: implement the PIDs subsystem

      Adds a new single-purpose PIDs subsystem to limit the number of
      tasks that can be forked inside a cgroup. Essentially this is an
      implementation of RLIMIT_NPROC that applies to a cgroup rather than a
      process tree.

      However, it should be noted that organisational operations (adding and
      removing tasks from a PIDs hierarchy) will *not* be prevented. Rather,
      the number of tasks in the hierarchy cannot exceed the limit through
      forking. This is due to the fact that, in the unified hierarchy, attach
      cannot fail (and it is not possible for a task to overcome its PIDs
      cgroup policy limit by attaching to a child cgroup -- even if migrating
      mid-fork it must be able to fork in the parent first).

      PIDs are fundamentally a global resource, and it is possible to reach
      PID exhaustion inside a cgroup without hitting any reasonable kmemcg
      policy. Once you've hit PID exhaustion, you're only in a marginally
      better state than OOM. This subsystem allows PID exhaustion inside a
      cgroup to be prevented.

      cgroup: allow a cgroup subsystem to reject a fork

      Add a new cgroup subsystem callback can_fork that conditionally
      states whether or not the fork is accepted or rejected by a cgroup
      policy. In addition, add a cancel_fork callback so that if an error
      occurs later in the forking process, any state modified by can_fork can
      be reverted.

      Allow for a private opaque pointer to be passed from cgroup_can_fork to
      cgroup_post_fork, allowing for the fork state to be stored by each
      subsystem separately.

      Also add a tagging system for cgroup_subsys.h to allow for CGROUP_<TAG>
      enumerations to be be defined and used. In addition, explicitly add a
      CGROUP_CANFORK_COUNT macro to make arrays easier to define.

      PCI: Shift PCI_CLASS_NOT_DEFINED consistently with other classes

      The PCI class in dev->class is a three-byte value comprising a base class,
      sub-class, and interface type.  PCI_CLASS_NOT_DEFINED includes the base
      class and sub-class, but not the interface type, so it should be shifted 
to
      make space for the interface.  It happens that PCI_CLASS_NOT_DEFINED is
      zero, so it doesn't matter in the end, but we should still use it
      consistently with other class definitions.

      Treat PCI_CLASS_NOT_DEFINED as a base class/sub-class value that should
      appear in bits 8-23 of dev->class.

      PCI: Revert aeb30016fec3 ("PCI: add Intel USB specific reset method")

      Revert aeb30016fec3 ("PCI: add Intel USB specific reset method").

      We checked for "dev->class == PCI_CLASS_SERIAL_USB", but dev->class
      contains the entire three-byte base class/sub-class/interface, while
      PCI_CLASS_SERIAL_USB is only the two-byte base class/sub-class.

      This error meant that we used the Intel device-specific reset on devices
      with class code 0x000c03 instead of those with class code 0x0c03xx.
      0x000c03 is a reserved value in the 0x00 backwards compatibility base
      class and shouldn't match any devices, so I think 
reset_intel_generic_dev()
      always failed.

      I considered adding a shift, but I can't test it, so it's as likely to
      break something as to fix something.

      PCI: Fix generic NCR 53c810 class code quirk

      In the generic quirk fixup_rev1_53c810(), added by a5312e28c195 ("[PATCH]
      PCI: NCR 53c810 quirk"), we assigned "class = PCI_CLASS_STORAGE_SCSI".  
But
      PCI_CLASS_STORAGE_SCSI is only the two-byte base class/sub-class and needs
      to be shifted to make space for the low-order interface byte.

      Furthermore, we had a similar quirk, pci_fixup_ncr53c810(), for arch/x86,
      which assigned class correctly.  The arch code is linked before the PCI
      core, so arch quirks run before generic quirks.  Therefore, on x86, the 
x86
      arch quirk ran first, and the generic quirk did nothing because it saw 
that
      dev->class was already set.  But on other arches, the generic quirk set 
the
      wrong class code.

      Fix the generic quirk to set the correct class code and remove the
      now-unnecessary x86-specific quirk.

      drm/i915: Readout initial hw mode, v2.

      Atomic requires a mode blob when crtc_state->enable is true, or
      you get a huge warn_on.

      With a few tweaks the mode we read out from hardware could be used
      as the real mode without a modeset, but this requires too much
      testing, so for now force a modeset the first time the mode blob's
      updated.

      This preserves the old behavior, because previously we never set
      the initial mode, which always meant that a modeset happened
      when the mode was first set.

      Changes since v1:
      - Add a description in intel_modeset_readout_hw_state of how the
        recalculation is done.

      drm/i915: Added Programming of the MOCS

      This change adds the programming of the MOCS registers to the gen 9+
      platforms. The set of MOCS configuration entries introduced by this
      patch is intended to be minimal but sufficient to cover the needs of
      current userspace - i.e. a good set of defaults. It is expected to be
      extended in the future to provide further default values or to allow
      userspace to redefine its private MOCS tables based on its demand for
      additional caching configurations. In this setup, userspace should
      only utilize the first N entries, higher entries are reserved for
      future use.

      It creates a fixed register set that is programmed across the different
      engines so that all engines have the same table. This is done as the
      main RCS context only holds the registers for itself and the shared
      L3 values. By trying to keep the registers consistent across the
      different engines it should make the programming for the registers
      consistent.

      v2:
      -'static const' for private data structures and style changes.(Matt 
Turner)
      v3:
      - Make the tables "slightly" more readable. (Damien Lespiau)
      - Updated tables fix performance regression.
      v4:

      - re-privatised mocs code. (Daniel Vetter)
      v5:

      v7 (Francisco Jerez):
      - Don't write L3-specific MOCS_ESC/SCC values into the e/LLC control

        e/LLC-specific defines with LE_ to avoid this kind of confusion in
        the future.
      - Change L3CC WT define back to RESERVED (matches my hardware
        documentation and the original patch, probably a misunderstanding
        of my own previous comment).
      - Drop Android tables, define new minimal tables more suitable for the

      drm/i915: Do not use plane_config in intel_fbdev.c

      Use the atomic state instead, this allows removing plane_config
      from the crtc after the full hw readout is completed.

      The size can be found in the fb, no need for the plane_config.

      drm/i915: Do not update pfit state when toggling crtc enabled.

      There's not much point for calculating the changes for the old
      state. Instead just disable all scalers when disabling. It's
      probably good enough to just disable the crtc_scaler, but just in
      case there's a bug disable all scalers.

      This means intel_atomic_setup_scalers is only called in the crtc
      check function now, so all the transitional code can be removed.

      drm/i915: Only update state on crtc's that are part of the atomic state.

      This is probably hard to hit right now because in most cases all
      atomic locks are taken, but after conversion to atomic this will make
      it more likely to corrupt the crtc->config pointer, resulting in hard
      to find bugs.

      In addition to the regular mux configuration such as mux mode 1,
      2 etc, certain pins of DRA7 require to have "virtual mode" also
      programmed. This allows for predefined delay characteristics to
      be used by the SoC to meet timing characterstics needed for the
      interface.

      Provide easy to use macro to do the same.

      It is important to note that the official TI guidelines recommend
      to do as minimal pin reconfiguration beyond the bootloader given
      the design of the hardware involved which can result in substantial
      glitches which may impair functionality of certain peripherals.

      Most commonly, this is 512MB NAND from the Micron MT29C4G96MAZ family
      but, as discussed [1], several different sized are possible. To
      support different sizes, the last partition should fill to the end of
      the chip (i.e. MTDPART_SIZ_FULL).

      regmap: Silence warning on invalid zero length read

      Zero length reads make no sense in a regmap context and are likely to
      trigger bugs further down the stack so insert an error check, also
      silencing compiler warnings about use of ret in cases where we iterate
      per register.

      drm/gem: rip out drm vma accounting for gem mmaps

      Doesn't really add anything which can't be figured out through
      proc files. And more clearly separates the new gem mmap handling
      code from the old drm maps mmap handling code, which is surely a
      good thing.

      gpio/davinci: Fix race in installing chained irq handler

      Fix a race where a pending interrupt could be received and the handler
      called before the handler's data has been setup, by converting to
      irq_set_chained_handler_and_data().

      crypto: seqiv - Replace seqniv with seqiv

      This patch replaces the seqniv generator with seqiv when the
      underlying algorithm understands the new calling convention.

      This not only makes more sense as now seqiv is solely responsible
      for IV generation rather than also determining how the IV is going
      to be used, it also allows for optimisations in the underlying
      implementation.  For example, the space for the IV could be used
      to add padding for authentication.

      This patch also removes the unnecessary copying of IV to dst
      during seqiv decryption as the IV is part of the AD and not cipher
      text.

      During decryption there is no need to copy the IV to dst because
      it's now part of the AD.

      This patch removes an unncessary check on authsize which would be
      performed by the underlying decrypt call.

      crypto: api - Add instance free function to crypto_type

      Currently the task of freeing an instance is given to the crypto
      template.  However, it has no type information on the instance so
      we have to resort to checking type information at runtime.

      This patch introduces a free function to crypto_type that will be
      used to free an instance.  This can then be used to free an instance
      in a type-safe manner.

      EDAC, mce_amd: Don't emit 'CE' for Deferred error

      Currently, when decoding an MCE, we display 'CE' for a Deferred error, 
like
      this:

      [Hardware Error]: CPU:0 (15:2:0) 
MC4_STATUS[Over|CE|MiscV|-|AddrV|Deferred|-|UECC]: 0xdc04b00095080813

      When the 'UC' bit in the MCx_STATUS register is clear, the error status
      is either a Corrected error or Deferred error as determined by the
      'Deferred' bit. So do not print 'CE' on a deferred error.

      Refer to AMD Error Scope Hierarchy table in a newer BKDG (example:
      49125_15h_Models_30h-3Fh_BKDG.pdf, section "RAS Features").

      clk: st: Fix error paths and allocation style

      The error paths in this file leak memory and mappings and test
      for pointers being valid after dereferencing them. Fix these
      problems and properly free resources on errors. Fix some
      stylistic things too like using sizeof(*ptr) and fitting more
      code on a single line. Note that we don't unregister clocks here.
      That needs a clk_composite_unregister() API that we don't have
      right now.

      bridge: mdb: add vlan support for user entries

      Until now all user mdb entries were added in vlan 0, this patch adds
      support to allow the user to specify the vlan for the entry.
      About the uapi change a hole in struct br_mdb_entry is used so the size
      and offsets are kept the same (verified with pahole and tested with older
      iproute2).

      Example:
      $ bridge mdb
      dev br0 port eth1 grp 239.0.0.1 permanent vlan 2000
      dev br0 port eth1 grp 239.0.0.1 permanent vlan 200

      ebpf: remove self-assignment in interpreter's tail call

      ARG1 = BPF_R1 as it stands, evaluates to regs[BPF_REG_1] = regs[BPF_REG_1]
      and thus has no effect. Add a comment instead, explaining what happens and
      why it's okay to just remove it. Since from user space side, a tail call 
is
      invoked as a pseudo helper function via bpf_tail_call_proto, the verifier
      checks the arguments just like with any other helper function and makes
      sure that the first argument (regs[BPF_REG_1])'s type is ARG_PTR_TO_CTX.

      net: Build IPv6 into kernel by default

      This patch makes the default to build IPv6 into the kernel. IPv6
      now has significant traction and any remaining vestiges of IPv6
      not being provided parity with IPv4 should be swept away. IPv6 is now
      core to the Internet and kernel.

      Points on IPv6 adoption:

      - Per Google statistics, IPv6 usage has reached 7% on the Internet
        and continues to exhibit an exponential growth rate
        https://www.google.com/intl/en/ipv6/statistics.html
      - Just a few days ago ARIN officially depleted its IPv4 pool
      - IPv6 only data centers are being successfully built
        (e.g. at Facebook)

      This patch changes the IPv6 Kconfig for IPV6. Default for CONFIG_IPV6
      is set to "y" and the text has been updated to reflect the maturity of
      IPv6.

      Impact:

      Under some circumstances building modules in to kernel might have a
      performance advantage. In my testing, I did notice a very slight
      improvement.

      This will obviously increase the size of the kernel image. In my
      configuration I see:

      IPv6 as module:

         text    data     bss     dec     hex filename
      9703666 1899288  933888 12536842         bf4c0a vmlinux

      IPv6 built into kernel

        text     data     bss     dec     hex filename
      9436490 1879600  913408 12229498         ba9b7a vmlinux

      Which increases text size by ~270K (2.8% increase in size for me). If
      image size is an issue, presumably for a device which does not do IP
      networking (IMO we should be discouraging IPv4-only devices), IPV6 can
      be disabled or still built as a module.

      selinux: initialize sock security class to default value

      Initialize the security class of sock security structures
      to the generic socket class.  This is similar to what is
      already done in inode_alloc_security for files.  Generally
      the sclass field will later by set by socket_post_create
      or sk_clone or sock_graft, but for protocol implementations
      that fail to call any of these for newly accepted sockets,
      we want some sane default that will yield a legitimate
      avc denied message with non-garbage values for class and
      permission.

      selinux: reduce locking overhead in inode_free_security()

      The inode_free_security() function just took the superblock's isec_lock
      before checking and trying to remove the inode security struct from the
      linked list. In many cases, the list was empty and so the lock taking
      is wasteful as no useful work is done. On multi-socket systems with
      a large number of CPUs, there can also be a fair amount of spinlock
      contention on the isec_lock if many tasks are exiting at the same time.

      This patch changes the code to check the state of the list first before
      taking the lock and attempting to dequeue it. The list_del_init()
      can be called more than once on the same list with no harm as long
      as they are properly serialized. It should not be possible to have
      inode_free_security() called concurrently with list_add(). For better
      safety, however, we use list_empty_careful() here even though it is
      still not completely safe in case that happens.

      selinux: extended permissions for ioctls

      Add extended permissions logic to selinux. Extended permissions
      provides additional permissions in 256 bit increments. Extend the
      generic ioctl permission check to use the extended permissions for
      per-command filtering. Source/target/class sets including the ioctl
      permission may additionally include a set of commands. Example:

      allowxperm <source> <target>:<class> ioctl unpriv_app_socket_cmds
      auditallowxperm <source> <target>:<class> ioctl priv_gpu_cmds

      Where unpriv_app_socket_cmds and priv_gpu_cmds are macros
      representing commonly granted sets of ioctl commands.

      When ioctl commands are omitted only the permissions are checked.
      This feature is intended to provide finer granularity for the ioctl
      permission that may be too imprecise. For example, the same driver
      may use ioctls to provide important and benign functionality such as
      driver version or socket type as well as dangerous capabilities such
      as debugging features, read/write/execute to physical memory or
      access to sensitive data. Per-command filtering provides a mechanism
      to reduce the attack surface of the kernel, and limit applications
      to the subset of commands required.

      The format of the policy binary has been modified to include ioctl
      commands, and the policy version number has been incremented to
      POLICYDB_VERSION_XPERMS_IOCTL=30 to account for the format
      change.

      The extended permissions logic is deliberately generic to allow
      components to be reused e.g. netlink filters

      HID: wacom: remove the extra Pen interface for Wacom Bamboo PAD

      the touch through this current interface.

      Clearing the WACOM_DEVICETYPE_PEN bit removes the extra unused interface

      The UDA134X family extends the rather limited L3 register set by using

      These extra address bits are currently stored in the default register 
cache
      and rely on them remaining constant. While this works it is rather

      regmap: Add better support for devices without readback support

      Currently regmap requires that a reg_read callback is supplied, otherwise 
a
      warning is emitted each time regmap_read() is called. This means a device
      or bus without readback support needs to supply dummy reg_read callback.
      Apart from that regmap_read() will still work fine if a cache is used.

      Remove the warning and let regmap_readable() return false if not reg_read
      callback is supplied. This means a device no longer has to supply a dummy
      callback if it does not support readback and it also doesn't have to have 
a
      readable_reg callback that always returns false since this is now 
implicit.

      drm/i915: Update PM interrupts before updating the freq

      Currently we update the freq before masking the interrupts, which can
      allow new interrupts to occur before the frequency has changed. These
      extra interrupts might waste some cpu cycles. This patch corrects
      this by masking interrupts prior to updating the frequency.

      Note from Chris:
      "Well it won't waste CPU cycles as the interrupt is also masked by the
      threshold limits, but there should be no harm at all in reordering the
      patch so, and it does make a certain amount of sense."

      ARM: OMAP2+: Remove legacy booting support for LogicPD Torpedo

      We've been moving all omap2+ based systems to boot in device tree only
      mode for a few years now. Only omap3 has legacy booting support
      remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
      files for booting with device tree.

      This board has support for device tree based booting, and we've been
      printing warnings about the legacy booting being deprecated for a
      few merge cycles now. Let's attempt to remove the legacy booting
      for it.

      The reason for removing the legacy booting support now rather than
      later is we can simply revert this patch if necessary if we run
      into some unexpected issues that are not trivial to fix for the
      device tree based booting.

      powerpc/iommu: Cleanup setting of DMA base/offset

      Now that the table and the offset can co-exist, we no longer need
      to flip/flop, we can just establish both once at boot time.

      powerpc/iommu: Remove dma_data union

      To support "hybrid" DMA ops in a subsequent patch, we will need both
      a direct DMA offset and an iommu pointer. Those are currently exclusive
      (a union), so change them to be separate fields.

      While there, also type iommu_table_base properly and make exist only
      on CONFIG_PPC64 since it's not referenced on 32-bit at all.

      cxl: use more common format specifier

      A precision of 16 (%.16llx) has the same effect as a field width of 16
      along with passing the 0 flag (%016llx), but the latter is much more
      common in the kernel tree. Update cxl to use that.

      cxl: Add explicit precision specifiers

      C99 says that a precision given as simply '.' with no following digits
      or * should be interpreted as 0. The kernel's printf implementation,
      however, treats this case as if the precision was omitted. C99 also
      says that if both the precision and value are 0, no digits should be
      printed. Even if the kernel followed C99 to the letter, I don't think
      that would be particularly useful in these cases. For consistency with
      most other format strings in the file, use an explicit precision of 16
      and add a 0x prefix.

      jbd2: speedup jbd2_journal_dirty_metadata()

      It is often the case that we mark buffer as having dirty metadata when
      the buffer is already in that state (frequent for bitmaps, inode table
      blocks, superblock). Thus it is unnecessary to contend on grabbing
      journal head reference and bh_state lock. Avoid that by checking whether
      any modification to the buffer is needed before grabbing any locks or
      references.

      [ Note: this is a fixed version of commit 2143c1965a761, which was
        reverted in ebeaa8ddb3663b5 due to a false positive triggering of an

      Input: wdt87xx_i2c - change the sleep time to 2500ms after the sw reset

      The original wait time was 200ms which was enough for the firmware to
      finish loading and boot. After that the firmware will perform
      initialization and touch calibration, which will take about 1.1 second. 
The
      touch calibration will change controller frequency to scan at the most
      optimal frequency and during calibration/frequency switching process we 
may
      run into i2c data errors. To avoid them we extend the sleep to 2500ms 
after
      issuing the sw reset.

      Revert "ipv4: use skb coalescing in defragmentation"

      This reverts commit 3cc4949269e01f39443d0fcfffb5bc6b47878d45.

      There is nothing wrong with coalescing during defragmentation, it
      reduces truesize overhead and simplifies things for the receiving
      socket (no fraglist walk needed).

      However, it also destroys geometry of the original fragments.
      While that doesn't cause any breakage (we make sure to not exceed largest
      original size) ip_do_fragment contains a 'fastpath' that takes advantage
      of a present frag list and results in fragments that (in most cases)
      match what was received.

      In case its needed the coalescing could be done later, when we're sure
      the skb is not forwarded.  But discussion during NFWS resulted in
      'lets just remove this for now'.

      With commit 02b4e2756e01c623cc4dbceae4b07be75252db5b ("ARM: v7 setup
      function should invalidate L1 cache"), the default secondary_startup
      function for ARMv7 CPUs does invalidate the L1 cache, which was the sole
      reason why BCM63xx had to have its own secondary_startup implementation.

      Now that the secondary_startup takes care of this, we can completely
      remove that code.

      irqchip/sirfsoc: Fix generic chip allocation wreckage

      irq_alloc_domain_generic_chips() can only be called once for an
      irqdomain. The sirfsoc init calls it twice and because the return
      value is not checked it does not notice the wreckage.

      The code works by chance because the first call already allocates two
      chips and therefor the second call to sirfsoc_alloc_gc() operates on
      the proper generic chip instance.

      Use a single call and setup the two chips in the obvious correct way.

      irqchip/dw-apb-ictl: Fix generic domain chip wreckage

      The num_ct argument of irq_alloc_domain_generic_chips() tells the core
      code how many chip types (for different control flows,
      e.g. edge/level) should be allocated. It does not control how many
      generic chip instances are created because that's determined from the
      irq domain size and the number of interrupts per chip.

      The dw-apb init abuses the num_ct argument for allocating one or two
      chip types depending on the number of interrupts. That's completely
      wrong because the alternate type is never used.

      This code was obviously never tested on a system which has more than
      32 interrupts as that would have never worked due to the unitialized
      second generic chip instance.

      Hand in the proper num_ct=1 and fixup the chip initialization along
      with the interrupt handler.

      ath9k: DFS - add pulse chirp detection for FCC

      FCC long pulse radar (type 5) requires pulses to be
      checked for chirping. This patch implements chirp
      detection based on the FFT data provided for long
      pulses.

      A chirp is detected when a set of criteria defined
      by FCC pulse characteristics is met, including
      * have at least 4 FFT samples
      * max_bin index moves equidistantly between samples
      * the gradient is within defined range

      The chirp detection has been tested with reference
      radar generating devices and proved to work reliably.

      mac80211 already does provide complete IEs for
      Probe Requests for hw scan and ath10k firmware was
      appending duplicate Supported Rates IEs
      unnecessarily.

      In commit 418ca5992e2f ("ath10k: Make target cpu address to
      CE address conversion chip specific") mask 0x7fff is added
      by mistake instead of 0x7ff. Fix this regression.

      ath10k: fix QCA61X4 boot up

      commit a521ee983d312db7 ("ath10k: Add new reg_address/mask to hw register
      table") broke QCA61x4 support by providing wrong
      fw_indicator_address, which should have been 0x0003a028 instead of 
0x00009028.

      User experience was a failing boot up sequence (crashing device during
      initialization):

      [  181.663874] ath10k_pci 0000:02:00.0: enabling device (0000 -> 0002)

      [  181.689774] ath10k_pci: probe of 0000:02:00.0 failed with error -70

      Fix it by updating the address with correct value.

      ====================
      be2net: patch set

      Hi David, the following patch set has code cleanup patches, minor 
enhancements
      and non-critical fixes. Pls consider applying to the net-next tree. 
Thanks!

      Patch 1 removes duplicate code in be_setup_wol() routine making it simpler
      and more readable.

      Patch 2 fixes the the bridge mode return value for the 
ndo_bridge_getlink()
      call. Instead of just relying on the SRIOV enabled state, the driver now
      queries the FW, for the actual mode of bridge.

      Patch 3 removes code for setting D0 power state as it's already done
      in pci_enable_device()

      Patch 4 fixes a bad return value in be_check_ufi_compatibility() routine
      introduced by an earlier commit.

      Patch 5 fixes a field in udp header being accessed while in network endian
      format.

      Patch 6 fixes the be_mcc_notify() routine to return an error status when
      the FW/HW is in an error state.

      Patch 7 fixes the be_cmd_rx_filter() routine to issue the RX_FILTER cmd
      and not wait for a completion from the FW. If the FW/adapter
      is in an error state, this change helps in not holding up the rtnl_lock
      and keeping bottom halves disabled while the driver timesout waiting for
      a response from the FW.

      Patch 8 fixes the be_cmd_set_loopback() routine to issue the LOOPBACK cmd
      and not wait for the FW completion while spin_lock_bh() is held on the
      mcc_lock. As the cmd is always issued from ethtool in a process context,
      it can sleep till the FW completion is received.

      Patch 9 bumps up the driver version to 10.6.0.3

      be2net: make SET_LOOPBACK_MODE cmd asynchrounous

      The SET_LOOPBACK_MODE command is always issued from ethtool only in a
      process context. So, while waiting for the cmd to complete, the driver
      can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
      by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
      only after the cmd completes while the MCCQ is locked).

      be2net: make the RX_FILTER command asynchronous

      This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues
      this cmd and doesn't wait for a completion from the FW. If the FW/adapter
      is in an error state, this change helps in not holding up the rtnl_lock
      and keeping bottom halves disabled while the driver timesout waiting for
      a response from the FW.

      DocBook: Avoid building man pages repeatedly and inconsistently

      Some kernel-doc sections are included in multiple DocBook files.  This
      means the mandocs target will generate the same manual page multiple
      times with different metadata (author name/address and manual title,
      taken from the including DocBook file).  If it's invoked in a parallel
      build, the output is nondeterminstic.

      For each section that is duplicated, mark the less specific manual's
      inclusion as 'extra' and exclude it during conversion to manual pages.
      Use xmlif for this, as that is bundled with xmlto which we already
      use.

      I would have preferred to use more conventional markup for this, but
      each of the following approaches failed:

      1. Wrap the extra inclusions with a new element and add a template to
         the stylesheet to include/exclude them.  Unfortunately DocBook XSL
         doesn't seem to support foreign elements at an intermediate level
         in the document tree.
      2. Use DocBook profiling.  This works but requires passing an absolute
         path to the profile stylesheet to xmlto, so it's not portable.
      3. Use SGML marked sections.  docbook2x can handle these but xmlto
         chokes on them.

      mnt: fs_fully_visible enforce noexec and nosuid  if !SB_I_NOEXEC

      The filesystems proc and sysfs do not have executable files do not
      have exectuable files today and portions of userspace break if we do
      enforce nosuid and noexec consistency of nosuid and noexec flags
      between previous mounts and new mounts of proc and sysfs.

      Add the code to enforce consistency of the nosuid and noexec flags,
      and use the presence of SB_I_NOEXEC to signal that there is no need to
      bother.

      This results in a completely userspace invisible change that makes it
      clear fs_fully_visible can only skip the enforcement of noexec and
      nosuid because it is known the filesystems in question do not support
      executables.

      vfs: Commit to never having exectuables on proc and sysfs.

      Today proc and sysfs do not contain any executable files.  Several
      applications today mount proc or sysfs without noexec and nosuid and
      then depend on there being no exectuables files on proc or sysfs.
      Having any executable files show on proc or sysfs would cause
      a user space visible regression, and most likely security problems.

      Therefore commit to never allowing executables on proc and sysfs by
      adding a new flag to mark them as filesystems without executables and
      enforce that flag.

      Test the flag where MNT_NOEXEC is tested today, so that the only user
      visible effect will be that exectuables will be treated as if the
      execute bit is cleared.

      The filesystems proc and sysfs do not currently incoporate any
      executable files so this does not result in any user visible effects.

      This makes it unnecessary to vet changes to proc and sysfs tightly for
      adding exectuable files or changes to chattr that would modify
      existing files, as no matter what the individual file say they will
      not be treated as exectuable files by the vfs.

      Not having to vet changes to closely is important as without this we
      are only one proc_create call (or another goof up in the
      implementation of notify_change) from having problematic executables
      on proc.  Those mistakes are all too easy to make and would create
      a situation where there are security issues or the assumptions of
      some program having to be broken (and cause userspace regressions).

      ARM: 8395/1: l2c: Add support for the "arm,shared-override" property

      "CoreLink Level 2 Cache Controller L2C-310", p. 2-15, section 2.3.2
      Shareable attribute" states:

          "The default behavior of the cache controller with respect to the
           shareable attribute is to transform Normal Memory Non-cacheable
           transactions into:
              - cacheable no allocate for reads
              - write through no write allocate for writes."

      Depending on the system architecture, this may cause memory corruption
      in the presence of bus mastering devices (e.g. OHCI). To avoid such
      corruption, the default behavior can be disabled by setting the Shared
      Override bit in the Auxiliary Control register.

      Currently the Shared Override bit can be set only using C code:
        - by calling l2x0_init() directly, which is deprecated,
        - by setting/clearing the bit in the machine_desc.l2c_aux_val/mask
          fields, but using values differing from 0/~0 is also deprecated.

      Hence add support for an "arm,shared-override" device tree property for
      the l2c device node. By specifying this property, affected systems can
      indicate that non-cacheable transactions must not be transformed.
      Then, it's up to the OS to decide. The current behavior is to set the
      "shared attribute override enable" bit, as there may exist kernel linear
      mappings and cacheable aliases for the DMA buffers, even if CMA is
      enabled.

      See also commit 1a8e41cd672f894b ("ARM: 6395/1: VExpress: Set bit 22 in
      the PL310 (cache controller) AuxCtlr register"):

          "Clearing bit 22 in the PL310 Auxiliary Control register (shared
           attribute override enable) has the side effect of transforming
           Normal Shared Non-cacheable reads into Cacheable no-allocate reads.

           Coherent DMA buffers in Linux always have a Cacheable alias via the
           kernel linear mapping and the processor can speculatively load
           cache lines into the PL310 controller. With bit 22 cleared,
           Non-cacheable reads would unexpectedly hit such cache lines leading
           to buffer corruption."

      HID: cp2112: support i2c write-read transfers in hid-cp2112

      cp2112_i2c_xfer() only supports a single i2c_msg.  More than
      one message at a time just returns EIO.  This breaks certain
      important cases.  For example, the at24 eeprom driver generates
      paired write and read messages (for eeprom address and data).

      Since the device doesn't support i2c repeated starts in general,
      but does support a single write-repeated-start-read pair
      (since hardware rev 1), we recognize the latter case and
      implement only that.

      ipv6: Nonlocal bind

      Add support to allow non-local binds similar to how this was done for 
IPv4.
      Non-local binds are very useful in emulating the Internet in a box, etc.

      This add the ip_nonlocal_bind sysctl under ipv6.

      Testing:

      Set up nonlocal binding and receive routing on a host, e.g.:

      ip -6 rule add from ::/0 iif eth0 lookup 200
      ip -6 route add local 2001:0:0:1::/64 dev lo proto kernel scope host 
table 200
      sysctl -w net.ipv6.ip_nonlocal_bind=1

      Set up routing to 2001:0:0:1::/64 on peer to go to first host

      ping6 -I 2001:0:0:1::1 peer-address -- to verify

      inet: simplify timewait refcounting

      Once we realize it should be similar to established and

      tcp: update congestion state first before raising cwnd

      The congestion state and cwnd can be updated in the wrong order.
      For example, upon receiving a dubious ACK, we incorrectly raise
      the cwnd first (tcp_may_raise_cwnd()/tcp_cong_avoid()) because
      the state is still Open, then enter recovery state to reduce cwnd.

      For another example, if the ACK indicates spurious timeout or
      retransmits, we first revert the cwnd reduction and congestion
      state back to Open state.  But we don't raise the cwnd even though
      the ACK does not indicate any congestion.

      To fix this problem we should first call tcp_fastretrans_alert() to
      process the dubious ACK and update the congestion state, then call
      tcp_may_raise_cwnd() that raises cwnd based on the current state.

      tcp: do not slow start when cwnd equals ssthresh

      In the original design slow start is only used to raise cwnd
      when cwnd is stricly below ssthresh. It makes little sense
      to slow start when cwnd == ssthresh: especially
      when hystart has set ssthresh in the initial ramp, or after
      recovery when cwnd resets to ssthresh. Not doing so will
      also help reduce the buffer bloat slightly.

      tcp: v1 always send a quick ack when quickacks are enabled

      V1 of this patch contains Eric Dumazet's suggestion to move the per
      dst RTAX_QUICKACK check into tcp_in_quickack_mode(). Thanks Eric.

      I ran some tests and after setting the "ip route change quickack 1"
      knob there were still many delayed ACKs sent. This occured
      because when icsk_ack.quick=0 the !icsk_ack.pingpong value is
      subsequently ignored as tcp_in_quickack_mode() checks both these
      values. The condition for a quick ack to trigger requires
      that both icsk_ack.quick != 0 and icsk_ack.pingpong=0. Currently
      only icsk_ack.pingpong is controlled by the knob. But the
      icsk_ack.quick value changes dynamically depending on heuristics.
      The crux of the matter is that delayed acks still cannot be entirely
      disabled even with the RTAX_QUICKACK per dst knob enabled. This
      patch ensures that a quick ack is always sent when the RTAX_QUICKACK
      per dst knob is turned on.

      The "ip route change quickack 1" knob was recently added to enable
      quickacks. It was modeled around the TCP_QUICKACK setsockopt() option.
      This issue is that even with "ip route change quickack 1" enabled
      we still see delayed ACKs under some conditions. It would be nice
      to be able to completely disable delayed ACKs.

      Here is an example:

      # netstat -s|grep dela
          3 delayed acks sent

      For all routes enable the knob

      # ip route change quickack 1

      Generate some traffic across a slow link and we still see the delayed
      acks.

      # netstat -s|grep dela
          106 delayed acks sent
          1 delayed acks further delayed because of locked socket

      The issue is that both the "ip route change quickack 1" knob and
      the TCP_QUICKACK option set the icsk_ack.pingpong variable to 0.
      However at the business end in the __tcp_ack_snd_check() routine,
      tcp_in_quickack_mode() checks that both icsk_ack.quick != 0
      and icsk_ack.pingpong=0 in order to trigger a quickack. As
      icsk_ack.quick is determined by heuristics it can be 0. When
      that occurs the icsk_ack.pingpong value is ignored and a delayed
      ACK is sent regardless.

      This patch moves the RTAX_QUICKACK per dst check into the
      tcp_in_quickack_mode() routine which ensures that a quickack is
      always sent when the quickack knob is enabled for that dst.

      In the past frontbuffer was being invalidated on
      set_to_gtt_domain, but it moved to set_domain fixing that case,
      but left this behind and broken in

          drm/i915: Unconditionally do fb tracking invalidate in set_domain

      Note that even before this commit it wasn't perfect since the
      invalidate was omitted if the fbcon was already in the GTT domain,
      which it usually was.

      Since we are also invalidating in other fbdev cases this one
      was masked here. At least until now that I found this corner
      case: On boot with plymouth doing a splash screen
      when returning to the console frontbuffer wans't being invalidated
      causing missed screen updates with PSR enabled.

      So this patch fixes this issue.

          fix commit message indicating the set_domain fix
          as pointed out by Daniel.

      Let's trust VBT when it is set + 1  and use minimum of 4 + 1

      drm/i915: PSR: Remove Low Power HW tracking mask.

      By Spec we should only mask memup and hotplug detection
      for hardware tracking cases. However we always masked
      LPSP because with power well always enabled on audio
      PSR was never being activated and residency was always
      zeroed.

      Apparently audio driver is tying power well management
      and runtime PM for some reason. But with audio runtime
      PM working or with audio completely out of picture
      we should remove this mask, otherwise we have a high
      risk of miss screen updates as faced by Matthew.

      WARNING: With this patch if snd_intel_hda driver is
      running and not releasing power well properly PSR will
      constant Exit and Performance Counter will be 0.

      But the best thing of this patch is that with one more
      HW tracking working the risks of missed blank screen
      are minimized at most.

      This affects just core platforms where PSR exit are also
      helped by HW tracking: Haswell, Broadwell and Skylake
      for now.

      v2: Fix commit message explanation. It has nothing to do
      with runtime PM on i915 as previously advertised.

      regulator: pwm-regulator: Remove obsoleted property

      In "[3d7ef30] regulator: pwm-regulator: Simplify voltage to duty-cycle
      call" we stopped using max_duty_cycle, so we can retire it from device
      data and DT.

      There is no need to deprecate this property, as it hasn't hit Mainline
      yet.

      drm/i915: dirty fb operation flushsing frontbuffer

      Let's do a frontbuffer flush on dirty fb.
      To be used for DIRTYFB drm ioctl.

      This patch solves the biggest PSR known issue, that is
      missed screen updates during boot, mainly when there is a splash
      screen involved like Plymouth.

      Previously PSR was being invalidated by fbdev and Plymounth
      was taking control with PSR yet invalidated and could get screen
      updates normally. However with some atomic modeset changes
      Pymouth modeset over ioctl was now causing frontbuffer flushes
      making PSR gets back to work while it cannot track the
      screen updates and exit properly.

      By adding this flush on dirtyfb we properly track frontbuffer
      writes and properly exit PSR.

      Actually all mmap_wc users should call this dirty callback
      in order to have a proper frontbuffer tracking.

      In the future it can be extended to return 0 if the whole
      screen has being flushed or the number of rects flushed
      as Chris suggested.

      v2: Remove ORIGIN_FB_DIRTY and use ORIGIN_GTT instead since dirty
          callback is just called after few screen updates and not on
          everyone as pointed by Daniel.

      v3: Use flush instead of invalidate since flush means
          invalidate + flush and dirty means drawn had finished and
          it can be flushed.

      v4: Remove PSR from subject since it is purely frontbuffer tracking
          change and that can be useful for FBC as well.

      drm/i915: PSR: Flush means invalidate + flush

      Since flush actually means invalidate + flush we need to force psr
      exit on PSR flush.

      On Core platforms there is no way to disable hw tracking and
      do the pure sw tracking so we simulate it by fully disable psr and
      reschedule a enable back.
      So a good idea is to minimize sequential disable/enable in cases we
      know that HW tracking like when flush has been originated by a flip.
      Also flip had just invalidated it already.

      It also uses origin to minimize the a bit the amount of
      disable/enabled, mainly when flip already had invalidated.

      With this patch in place it is possible to do a flush on dirty areas
      properly in a following patch.

      v2: Remove duplicated exit on HSW+Sprites as pointed out by Paulo.

      power_supply: rt9455_charger: Properly notify userspace about charging 
events

      Charging events this patch refers to are:
      - charger is connected to/disconnected from the power source
      - battery is reconnected to the charger, after it was absent.

      When the charger is connected to/disconnected from the power source, 
CHRVPI
      interrupt occurs and PWR_RDY bit is either set or cleared. PWR_RDY bit is
      updated after 1-2 seconds CHRVPI interrupt has occurred.
      power_supply_changed() should be called after PWR_RDY bit is updated.
      /sys/class/power_supply/rt9455-charger/online file displays the value of
      PWR_RDY bit.
      This way, if the userspace is notified that a charging event has occurred
      and the userspace reads /sys/class/power_supply/rt9455-charger/online 
file,
      this file is properly updated when the userspace reads it.
      This is the reason why power_supply_changed() is called in
      rt9455_pwr_rdy_work_callback(), instead of being called in interrupt
      handler.

      Since no interrupt is triggered when the battery is reconnected to the
      charger, the userspace is never notified that the battery is reconnected.
      This is why power_supply_changed() is called in
      rt9455_max_charging_time_work_callback(), so that the userspace is 
notified
      that the battery is reconnected.

      hv_netvsc: Add support to set MTU reservation from guest side

      When packet encapsulation is in use, the MTU needs to be reduced for
      headroom reservation.
      The existing code takes the updated MTU value only from the host side.
      But vSwitch extensions, such as Open vSwitch, require the flexibility
      to change the MTU to different values from within a guest during the
      lifecycle of a vNIC, when the encapsulation protocol is changed. The
      patch supports this kind of MTU changes.

      net_sched: act: lockless operation

      As mentioned by Alexei last week in Budapest, it is a bit weird
      to take a spinlock in order to drop a packet in a tc filter...

      Lets add percpu infra for tc actions and use it for gact & mirred.

      Before changes, my host with 8 RX queues was handling 5 Mpps with gact,
      and more than 11 Mpps after.

      Mirred change is not yet visible if ifb+qdisc is used, as ifb is
      not yet multi queue enabled, but is a step forward.

      net_sched: act_gact: remove spinlock in fast path

      Final step for gact RCU operation :

      1) Use percpu stats
      2) update lastuse only every clock tick to avoid false sharing
      3) Remove spinlock acquisition, as it is no longer needed.

      Since this is the last contended lock in packet RX when tc gact is used,
      this gives impressive gain.

      My host with 8 RX queues was handling 5 Mpps before the patch,
      and more than 11 Mpps after patch.

      Tested:

      On receiver :

      dev=eth0
      tc qdisc del dev $dev ingress 2>/dev/null
      tc qdisc add dev $dev ingress
      tc filter del dev $dev root pref 10 2>/dev/null
      tc filter del dev $dev pref 10 2>/dev/null
      tc filter add dev $dev est 1sec 4sec parent ffff: protocol ip prio 1 \
        u32 match ip src 7.0.0.0/8 flowid 1:15 action drop

      tcp: reducing lost retransmits in recovery

      This patch series reduces lost retransmits in recovery, in particular
      when dealing with traffic policers. The main problem is that
      slow start in recovery under policing can cause massive lost and
      retransmit storms: any excess sending rate turns into drops. The
      solution is to avoid doing slow start when lost retransmit is
      detected and use packet conservation instead.

      On networks with traffic policers the patches have lowered the
      TCP loss rates by ~20% from Google servers without latency regressions.

      tcp: PRR uses CRB mode by default and SS mode conditionally

      PRR slow start is often too aggressive especially when drops are
      caused by traffic policers. The policers mainly use token bucket
      to enforce the rate so sending (twice) faster than the delivery
      rate causes excessive drops.

      This patch changes PRR to the conservative reduction bound
      (CRB) mode in RFC 6937 by default. CRB follows the packet
      conservation rule to send at most the delivery rate by default.

      But if many packets are lost and the pipe is empty, CRB may take N
      round trips to repair N losses. We conditionally turn on slow start
      mode if all these conditions are made to speed up the recovery:

        1) on the second round or later in recovery
        2) retransmission sent in the previous round is delivered on this ACK
        3) no retransmission is marked lost on this ACK

      By using packet conservation by default, this change reduces the loss
      retransmits signicantly on networks that deploy traffic policers,
      up to 20% reduction of overall loss rate.

      tcp: reduce cwnd if retransmit is lost in CA_Loss

      If the retransmission in CA_Loss is lost again, we should not
      continue to slow start or raise cwnd in congestion avoidance mode.
      Instead we should enter fast recovery and use PRR to reduce cwnd,
      following the principle in RFC5681:

      "... or the loss of a retransmission, should be taken as two
       indications of congestion and, therefore, cwnd (and ssthresh) MUST
       be lowered twice in this case."

      This is especially important to reduce loss when the CA_Loss
      state was caused by a traffic policer dropping the entire inflight.
      The CA_Loss state has a problem where a loss of L packets causes the
      sender to send a burst of L packets. So a policer that's dropping
      most packets in a given RTT can cause a huge retransmit storm. By
      contrast, PRR includes logic to bound the number of outbound packets
      that result from a given ACK. So switching to CA_Recovery on lost
      retransmits in CA_Loss avoids this retransmit storm problem when
      in CA_Loss.

      drm/i915: Update wa_ctx_emit() macro as per kernel coding guidelines

      wa_ctx_emit() depends on the name of a local variable; if the name of that
      variable is changed then we get compile errors. In this case it is 
unlikely
      to be changed as this macro is only used in this set of functions but
      Kernel coding guidelines doesn't recommend doing this. It was my mistake
      as I should have corrected it at the beginning but missed so correct
      this before there are more usages of this macro (Bob Beckett).

      2) macros that depend on having a local variable with a magic name:

         #define FOO(val) bar(index, val)

      might look like a good thing, but it's confusing as hell when one reads 
the
      code and it's prone to breakage from seemingly innocent changes.
      "

      v2: Optimization to avoid multiple evaluation of 'index' in the macro.
      Since we invoke it multiple times, compiler, if it can, should be able to 
coalesce
      them into a single condition and remove multiple WARN_ON checks (Chris).

      HID: i2c-hid: Call device suspend callback before disabling irq

      i2c-hid takes care of requesting and handling IRQs for HID devices
      which in turns might expect them to be always active when working
      in normal conditions. Hence, disabling IRQs before calling the suspend
      callbacks can potentially cause problems since device drivers might
      try to perform operations needing them.

      Fix this by disabling IRQs only after the suspend callbacks had been
      executed.

      Because the cool kids use dev_priv and FBC wants to be cool too.

      We've been historically using struct drm_device on the FBC function
      arguments, but we only really need it for intel_vgpu_active(): we can
      use dev_priv everywhere else. So let's fully switch to dev_priv since
      I'm getting tired of adding "struct drm_device *dev = dev_priv->dev"
      everywhere.

      If I get a NACK here I'll propose the opposite: convert all the
      functions that currently take dev_priv to take dev.

      Audigy has "Analog Capture Boost" mixer control,
      however now this only controls mic level, not
      other analog sources.

      It applies also both to playback and capture,
      so rename it to something more descriptive.

      According to Creative doc

      regulator: pwm-regulator: Don't assign structure attributes right away

      Perhaps this is just personal preference, but ...

      This patch introduces a new local variable to receive and test regulator
      initialisation data.  It simplifies and cleans up the code making it
      that little bit easier to read and maintain.  The local value is assigned
      to the structure attribute when all the others are.  This is the way we
      usually do things.

      Prevents this kind of nonsense:

        this->is->just.silly = fetch_silly_value(&pointer);
        if (!this->is->just.silly) {
                printk("Silly value failed: %d\n", this->is->just.silly);

      regulator: pwm-regulator: Simplify voltage to duty-cycle call

      If we reverse some of the logic and change the formula used,
      we can simplify the function greatly.

      It is intentional that this function is supplied and then re-worked
      within the same patch-set.  The submission in the previous patch is
      the tried and tested (i.e. in real releases) method written by ST.
      This patch contains a simplification provided later.  It looks and
      performs better, but doesn't have the same time-under-test that the
      original method does.  The idea is that we keep some history in
      order to provide an easy way back i.e. revert.

      regulator: pwm-regulator: Add support for continuous-voltage

      The current version of PWM regulator only supports a static table
      approach, where pre-calculated values are supplied by the vendor and
      obtained via DT.  The continuous-voltage method takes min_uV and
      max_uV, and divides the difference between them up into a number of
      slices.  The number of slices depend on how large the duty cycle
      register is.  This information is provided by a DT property.

      As the name alludes, this provides values for a continuous voltage
      range between min_uV and max_uV, which has obvious benefits over
      either limited voltage possibilities, or the requirement to provide
      a large voltage-table.

      ASoC: dpcm: Add checks of playback/capture before dpcm_get_be

      In dpcm_get_be(), it looks for a BE rtd that has the DAI widget
      according to current stream type. Only playback_widgets are searched
      in the case of playback stream and vice versa. However, the DAI widget
      itself can be playback or capture.

      If the DAI widget is capture, but current stream type is playback,
      dpcm_get_be() will always fail to find a rtd, print error messages,
      and continue to the next DAI widget in list. We can just skip this
      DAI widget to further suppress error messages. This happens in a
      special case when 2 codecs are inter-connected, and the 1st codec's
      "capture" widget is used to send data to the 2nd codec during "playback":

      mtk-rt5650-rt5676 sound: ASoC: can't get playback BE for Sub AIF2 Capture
      rt5650_rt5676 Playback: ASoC: no BE found for Sub AIF2 Capture

      Add checks to continue to next DAI widget if current DAI widget's
      direction does not match the stream type.

      Add support to configure Enhanced Transient Response Enable (ETR)
      and Sensitivity Selection based on maximum current i.e. expected
      load on that rail.

      Maxim recommended as:
      - Enable ETR with high sensitivity (75mV/us) for 0 to 9A expected loads,
      - Enable ETR with low sensitivity (150mV/us) for 9A to 12A expected loads.
      - Disable ETR for expected load > 12A.

      These recommendation will be configured for MAX77621 when maximum load
      is provided through regulator constraint for maximum current from 
platform.

      regulator: max8973: add support to configure ETR from DT

      The MAX8973/MAX77621 feature an Enhanced Transient Response(ETR)
      circuit that is enabled through software. The enhanced transient
      response reduces the voltage droop during large load steps by
      temporarily allowing all three phases to fire in unison, slewing
      total inductor current faster than would normally be possible if
      all three phases continued to operate 120deg out of phase. The
      enhanced transient response detector features two selectable
      sensitivity settings, which select the output voltage slew rate
      during load transients that triggers the ETR circuit. The sensitivity
      of the ETR detector is set by the CKADV[1:0] bits in the CONTROL2
      register.

      Add support to configure the ETR through platform data from DT.
      Update the DT binding document accordingly.

      spi: Fix per-page mapping of unaligned vmalloc-ed buffer

      spi_map_buf() processes mapping of vmalloc-ed buffers in a special way,
      making mapping of every page separately. However, if the buffer is not
      aligned to page boundary (e.g. sub-array in a vmalloc-ed array), it
      fills the scatter table with page-size unaligned pieces, that cross
      page boundaries. This is incorrect and can, for example, cause memory
      corruption and various crashes when working with ubifs on spi-nor chips
      (though those drivers are themselves buggy in that they should be
      providing DMAable memory to the SPI framework).

      Fix this by using proper scatter table size and intra-page buffer lengths,
      so that the whole buffer splits into separate scatter table entries on
      page boundaries.

      x86/entry: Remove exception_enter() from most trap handlers

      On 64-bit kernels, we don't need it any more: we handle context
      tracking directly on entry from user mode and exit to user mode.

      On 32-bit kernels, we don't support context tracking at all, so
      these callbacks had no effect.

      Note: this doesn't change do_page_fault().  Before we do that,
      we need to make sure that there is no code that can page fault
      from kernel mode with CONTEXT_USER.  The 32-bit fast system call
      stack argument code is the only offender I'm aware of right now.

      x86/entry: Add new, comprehensible entry and exit handlers written in C

      The current x86 entry and exit code, written in a mixture of assembly and
      C code, is incomprehensible due to being open-coded in a lot of places
      without coherent documentation.

      It appears to work primary by luck and duct tape: i.e. obvious runtime
      failures were fixed on-demand, without re-thinking the design.

      Due to those reasons our confidence level in that code is low, and it is
      very difficult to incrementally improve.

      Add new code written in C, in preparation for simply deleting the old
      entry code.

      prepare_exit_to_usermode() is a new function that will handle all
      slow path exits to user mode.  It is called with IRQs disabled
      and it leaves us in a state in which it is safe to immediately
      return to user mode.  IRQs must not be re-enabled at any point
      after prepare_exit_to_usermode() returns and user mode is actually
      entered. (We can, of course, fail to enter user mode and treat
      that failure as a fresh entry to kernel mode.)

      All callers of do_notify_resume() will be migrated to call
      prepare_exit_to_usermode() instead; prepare_exit_to_usermode() needs
      to do everything that do_notify_resume() does today, but it also
      takes care of scheduling and context tracking.  Unlike
      do_notify_resume(), it does not need to be called in a loop.

      syscall_return_slowpath() is exactly what it sounds like: it will
      be called on any syscall exit slow path. It will replace
      syscall_trace_leave() and it calls prepare_exit_to_usermode() on the
      way out.

      x86/entry: Add enter_from_user_mode() and use it in syscalls

      Changing the x86 context tracking hooks is dangerous because
      there are no good checks that we track our context correctly.
      Add a helper to check that we're actually in CONTEXT_USER when
      we enter from user mode and wire it up for syscall entries.

      Subsequent patches will wire this up for all non-NMI entries as
      well.  NMIs are their own special beast and cannot currently
      switch overall context tracking state.  Instead, they have their
      own special RCU hooks.

      This is a tiny speedup if !CONFIG_CONTEXT_TRACKING (removes a
      branch) and a tiny slowdown if CONFIG_CONTEXT_TRACING (adds a
      layer of indirection).  Eventually, we should fix up the core
      context tracking code to supply a function that does what we
      want (and can be much simpler than user_exit), which will enable
      us to get rid of the extra call.

      x86/traps, context_tracking: Assert that we're in CONTEXT_KERNEL in 
exception entries

      Other than the super-atomic exception entries, all exception
      entries are supposed to switch our context tracking state to
      CONTEXT_KERNEL. Assert that they do.  These assertions appear
      trivial at this point, as exception_enter() is the function
      responsible for switching context, but I'm planning on reworking
      x86's exception context tracking, and these assertions will help
      make sure that all of this code keeps working.

      x86/entry: Move C entry and exit code to arch/x86/entry/common.c

      Once x86 exports its do_signal(), the prototypes will clash.

      Fix the clash and also improve the code a bit: remove the
      unnecessary kern_do_signal() indirection. This allows
      interrupt_end() to share the 'regs' parameter calculation.

      Also remove the unused return code to match x86.

      Minimally build and boot tested.

      x86/entry/64/compat: Fix bad fast syscall arg failure path

      If user code does SYSCALL32 or SYSENTER without a valid stack,
      then our attempt to determine the syscall args will result in a
      failed uaccess fault.  Previously, we would try to recover by
      jumping to the syscall exit code, but we'd run the syscall exit
      work even though we never made it to the syscall entry work.

      Clean it up by treating the failure path as a non-syscall entry
      and exit pair.

      This fixes strace's output when running the syscall_arg_fault
      test. Without this fix, strace would get out of sync and would
      fail to associate syscall entries with syscall exits.

      x86/entry, selftests/x86: Add a test for 32-bit fast syscall arg faults

      This test passes on 4.0 and fails on some newer kernels.
      Fortunately, the failure is likely not a big deal.

      This test will make sure that we don't break it further (e.g. OOPSing)
      as we clean up the entry code and that we eventually fix the
      regression.

      There's arguably no need to preserve the old ABI here --
      anything that makes it into a fast (vDSO) syscall with a bad
      stack is about to crash no matter what we do.

      sched/fair: Clean up the __sched_period() code

      Since commit:

        4bf0b77158 ("sched: remove do_div() from __sched_slice()")

      ... the logic of __sched_period() can be implemented as a single if-else
      without any local variables, so this patch cleans it up with an if-else
      statement, which expresses the function's logic straightforwardly.

      sched/numa: Consider 'imbalance_pct' when comparing loads in 
numa_has_capacity()

      This is consistent with all other load balancing instances where we
      absorb unfairness upto env->imbalance_pct. Absorbing unfairness upto
      env->imbalance_pct allows to pull and retain task to their preferred
      nodes.

      sched/numa: Prefer NUMA hotness over cache hotness

      The current load balancer may not try to prevent a task from moving
      out of a preferred node to a less preferred node. The reason for this
      being:

       - Since sched features NUMA and NUMA_RESIST_LOWER are disabled by
         default, migrate_degrades_locality() always returns false.

       - Even if NUMA_RESIST_LOWER were to be enabled, if its cache hot,
         migrate_degrades_locality() never gets called.

      The above behaviour can mean that tasks can move out of their
      preferred node but they may be eventually be brought back to their
      preferred node by numa balancer (due to higher numa faults).

      To avoid the above, this commit merges migrate_degrades_locality() and
      migrate_improves_locality(). It also replaces 3 sched features NUMA,
      NUMA_FAVOUR_HIGHER and NUMA_RESIST_LOWER by a single sched feature
      NUMA.

      drm: Update plane->fb also for page_flip

      The legacy page_flip driver entry point is the only one left which
      requires drivers to update plane->fb themselves. All the other entry
      hooks will patch things up for the driver as needed since no one seems
      to reliable get this right, see e.g. drm_mode_set_config_internal or
      the plane->fb/old_fb handling in drm_mode_atomic_ioctl.

      Therefore unify things, which allows us to ditch a TODO from
      drm_atomic_helper_page_flip.

      This should also help the atomic transition in i915 since we keep a
      bit of legacy cruft only around because of this special behaviour in
      ->page_flip.

      clk: rockchip: rk3288: add CLK_SET_RATE_PARENT to sclk_mac

      The dwmac ethernet controller on the rk3288 supports phys connected
      via rgmii and rmii. With rgmii phys it is expected that the mac clock
      is provided externally while with rmii phys the clock can be external
      but also generated from the plls. In the later case it of course needs
      be at 50MHz, which gets set from the dwmac_rk driver.
      As most devices use a rgmii phy it never surfaced so far that the mac
      clk mux, doesn't go up one lever to the pll clock in the rmii case with
      internal clock generation, as it is missing the CLK_SET_RATE_PARENT flag,
      and thus will not set the correct frequency in most cases.

      ufs_inode_get{frag,block}(): get rid of 'phys' argument

      Just pass NULL as locked_page in case of first block in the indirect
      chain.  Old calling conventions aside, a reason for having 'phys'
      was that ufs_inode_getfrag() used to be able to do _two_ allocations
      - indirect block and extending/reallocating a tail.  We needed
      locked_page for the latter (it's a data), but we also needed to
      figure out that indirect block is metadata.  So we used to pass
      non-NULL locked_page in all cases *and* used NULL phys as
      indication of being asked to allocate an indirect.

      With tail unpacking taken into a separate function we don't need
      those convolutions anymore.

      __ufs_truncate_blocks(): avoid excessive dirtying of indirect blocks

      There's a case when an indirect block gets dirtied for no good
      reason - when there's a hole starting in the middle of area
      covered by it and spanning past its end, and truncate() is done
      precisely to the beginning of the hole.

      The block is obviously not modified at all - all removals happen
      beyond it.  However, existing code ends up dirtying it just in
      case.  It's trivial to fix and while it's not a real bug by any
      stretch of imagination, it makes the damn thing harder to follow.

      ufs: ufs_trunc_...() has exclusion with everything that might cause 
allocations

        Currently - on lock_ufs(), eventually - on per-inode mutex.
      lock_ufs() used to be mere BKL, which is much weaker, so it needed
      those rechecks.  BKL doesn't provide any exclusion once we lose CPU;
      its blind replacement, OTOH, _does_.  Making that per-filesystem was
      an atrocity, but at least we can simplify life here.  And yes, we
      certainly need to make that sucker per-inode - these days inode.c and
      truncate.c uses are needed only to protect the block pointers.

      after lock_ufs() and held it until just before unlock_ufs(); the third
      one (statfs) could not be called from itself or from other two (remount
      and sync_fs).  Just use ->s_lock in statfs and don't bother with lock_ufs
      at all.

      ufs: don't use lock_ufs() for block pointers tree protection

      * stores to block pointers are under per-inode seqlock (meta_lock) and
      mutex (truncate_mutex)
      * fetches of block pointers are either under truncate_mutex, or wrapped
      into seqretry loop on meta_lock
      * all changes of ->i_size are under truncate_mutex and i_mutex
      * all changes of ->i_lastfrag are under truncate_mutex

      It's similar to what ext2 is doing; the main difference is that unlike
      ext2 we can't rely upon the atomicity of stores into block pointers -
      on UFS2 they are 64bit.  So we can't cut the corner when switching
      a pointer from NULL to non-NULL as we could in ext2_splice_branch()
      and need to use meta_lock on all modifications.

      We use seqlock where ext2 uses rwlock; ext2 could probably also benefit
      from such change...

      Another non-trivial difference is that with UFS we *cannot* have reader
      grab truncate_mutex in case of race - it has to keep retrying.  That
      might be possible to change, but not until we lift tail unpacking
      several levels up in call chain.

      After that commit we do *NOT* hold fs-wide serialization on accesses
      to block pointers anymore.  Moreover, lock_ufs() can become a normal
      mutex now - it's only used on statfs, remount and sync_fs and none
      of those uses are recursive.  As the matter of fact, *now* it can be
      collapsed with ->s_lock, and be eventually replaced with saner
      per-cylinder-group spinlocks, but that's a separate story.

      ASoC: wm0010: Remove redundant spi driver bus initialization

      In ancient times it was necessary to manually initialize the bus
      field of an spi_driver to spi_bus_type. These days this is done in
      spi_register_driver(), so we can drop the manual assignment.

      drm/i915: Don't dereference NULL plane while setting up scalers

      intel_atomic_setup_scalers() dereferences 'plane' before the plane has
      been assigned.  The plane ID assignment doing this dereference is only
      needed for debugging messages later in the function, so just move the
      assignment farther down the function to a point where plane will no
      longer be NULL.

      This was introduced in:

      x86/platform/intel/pmc_atom: Add Cherrytrail PMC interface

      The patch adds CHT PMC interface. This exposes all the South IP
      device power states and S0ix states for CHT. The bit map of
      FUNC_DIS and D3_STS_0 registers for SoCs are consistent. The
      D3_STS_1 and FUNC_DIS_2 registers, however, are not aligned.
      This is fixed by splitting a common mapping on per register basis.

      soc: Mediatek: Add SCPSYS power domain driver

      This adds a power domain driver for the Mediatek SCPSYS unit.

      The System Control Processor System (SCPSYS) has several power
      management related tasks in the system. The tasks include thermal
      measurement, dynamic voltage frequency scaling (DVFS), interrupt
      filter and lowlevel sleep control. The System Power Manager (SPM)
      inside the SCPSYS is for the MTCMOS power domain control.

      For now this driver only adds power domain support, the more
      advanced features are not yet supported. The driver implements
      the generic PM domain device tree bindings, the first user will
      most likely be the Mediatek AFE audio driver.

      x86/platform/intel/pmc_atom: Export accessors to PMC registers

      Export the pmc_atom_read() and pmc_atom_write() accessors to the PMC
      registers. On early initcall stages the functions will return
      -ENODEV, and caller has to wait when it will be available.

      Additionally make absence of debugfs a non-fatal error.

      The patch will be useful for the upcoming fixes regarding to the
      LPSS block found on Intel BayTrail-T and Braswell.

      tools lib api debugfs: Check for tracefs when reporting errors

      Now that we have two mountpoints, one for debugfs and another, for
      tracefs, we end up needing to check permissions for both, so, on
      a system with default config we were always asking the user to
      check the permission of the debugfs mountpoint, even when it was
      already sufficient. Fix it.

      E.g.:

        $ trace -e nanosleep usleep 1
        Error: No permissions to read 
/sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit)
        Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

        $ sudo mount -o remount,mode=755 /sys/kernel/debug
        $ trace -e nanosleep usleep 1
        Error: No permissions to read 
/sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit)
        Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug/tracing'

        $ sudo mount -o remount,mode=755 /sys/kernel/debug/tracing
        $ trace -e nanosleep usleep 1
           0.326 ( 0.061 ms): usleep/11961 nanosleep(rqtp: 0x7ffef1081c50) = 0

      Now when we have requests this deep on call chain, we can mark
      the elsp being submitted when it actually is. Remove temp variable
      and readjust commenting to more closely fit to the code.

      v2: Avoid tmp variable and reduce number of writes (Chris)

      x86/asm/tsc: Save an instruction in DECLARE_ARGS users

      Before, the code to do RDTSC looked like:

        rdtsc
        shl $0x20, %rdx
        mov %eax, %eax
        or  %rdx, %rax

      The "mov %eax, %eax" is required to clear the high 32 bits of RAX.

      By declaring low and high as 64-bit variables, the code is
      simplified to:

        rdtsc
        shl $0x20,%rdx
        or  %rdx,%rax

      Yes, it's a 2-byte instruction that's not on a critical path,
      but there are principles to be upheld.

      Every user of EAX_EDX_RET has been checked. I tried to check
      users of EAX_EDX_ARGS, but there weren't any, so I deleted it to
      be safe.

      ( There's no benefit to making "high" 64 bits, but it was the
        simplest way to proceed. )

      x86/asm/tsc, x86/kvm: Drop open-coded barrier and use rdtsc_ordered() in 
kvmclock

      __pvclock_read_cycles() used to have two barriers, one of which was 
unnecessary,
      which got removed after an initial version of this patch was sent.

      But the barrier is still open-coded unnecessarily - get rid of
      that barrier and clean up the code by just using rdtsc_ordered().

      x86/asm/tsc: Use rdtsc_ordered() in read_tsc() instead of get_cycles()

      There are two logical changes here.  First, this removes a check
      for cpu_has_tsc.  That check is unnecessary, as we don't
      register the TSC as a clocksource on systems that have no TSC.

      Second, it adds a barrier, thus preventing observable
      non-monotonicity.

      I suspect that the missing barrier was never a problem in
      practice because system calls themselves were heavy enough
      barriers to prevent user code from observing time warps due to
      speculation. (Without the corresponding barrier in the vDSO,
      however, non-monotonicity is easy to detect.)

      x86/asm/tsc/sync: Use rdtsc_ordered() in check_tsc_warp() and drop extra 
barriers

      Using get_cycles was unnecessary: check_tsc_warp() is not called
      on TSC-less systems. Replace rdtsc_barrier(); get_cycles() with
      rdtsc_ordered().

      While we're at it, make the somewhat more dangerous change of
      removing barrier_before_rdtsc after RDTSC in the TSC warp check
      code. This should be okay, though -- the vDSO TSC code doesn't
      have that barrier, so, if removing the barrier from the warp
      check would cause us to detect a warp that we otherwise wouldn't
      detect, then we have a genuine bug.

      rdtsc_barrier(); rdtsc() is an unnecessary mouthful and requires
      more thought than should be necessary. Add an rdtsc_ordered()
      helper and replace the trivial call sites with it.

      This should not change generated code. The duplication of the

      x86/asm/tsc: Use the full 64-bit TSC in delay_tsc()

      As a very minor optimization, delay_tsc() was only using the low
      32 bits of the TSC. It's a delay function, so just use the whole
      thing.

      x86/asm/tsc, x86/paravirt: Remove read_tsc() and read_tscp() paravirt 
hooks

      We've had ->read_tsc() and ->read_tscp() paravirt hooks since
      the very beginning of paravirt, i.e.,

        d3561b7fa0fb ("[PATCH] paravirt: header and stubs for 
paravirtualisation").

      AFAICT, the only paravirt guest implementation that ever
      replaced these calls was vmware, and it's gone. Arguably even
      vmware shouldn't have hooked RDTSC -- we fully support systems
      that don't have a TSC at all, so there's no point for a paravirt
      implementation to pretend that we have a TSC but to replace it.

      I also doubt that these hooks actually worked. Calls to rdtscl()
      and rdtscll(), which respected the hooks, were used seemingly
      interchangeably with native_read_tsc(), which did not.

      Just remove them. If anyone ever needs them again, they can try
      to make a case for why they need them.

      Before, on a paravirt config:
        text            data     bss     dec     hex filename
        12618257      1816384 1093632 15528273 ecf151 vmlinux

      After:
        text            data     bss     dec     hex filename
        12617207      1816384 1093632 15527223 eced37 vmlinux

      x86/asm/tsc, kvm: Remove vget_cycles()

      The only caller was KVM's read_tsc(). The only difference
      between vget_cycles() and native_read_tsc() was that
      vget_cycles() returned zero instead of crashing on TSC-less
      systems. KVM already checks vclock_mode() before calling that
      function, so the extra check is unnecessary. Also, KVM
      (host-side) requires the TSC to exist.

        cdc7957d1954 ("x86: move native_read_tsc() offline")

      ... native_read_tsc() was moved out of line, presumably for some
      now-obsolete vDSO-related reason. Undo it.

      The entire rdtsc, shl, or sequence is only 11 bytes, and calls
      via rdtscl() and similar helpers were already inlined.

      It is found that i915 will not reset gpu under execlist mode when
      unload module. that will lead to some issues when unload/load module
      with different submission mode. e.g. from execlist mode to ring
      buffer mode via loading/unloading i915. Because HW is not in a reset
      state and registers are not clean under such condition.

      drm/i915: Update WaFlushCoherentL3CacheLinesAtContextSwitch

      In this WA we need to set GEN8_L3SQCREG4[21:21] and reset it after 
PIPE_CONTROL
      instruction but there is a slight complication as this is applied in WA 
batch
      where the values are only initialized once.
      Dave identified an issue with the current implementation where the 
register value
      is read once at the beginning and it is reused; this patch corrects this 
by saving
      the register value to memory, update register with the bit of our 
interest and
      restore it back with original value.

      This implementation uses MI_LOAD_REGISTER_MEM which is currently only used
      by command parser and was using a default length of 0. This is now updated
      with correct length and moved to appropriate place.

      Make sure we're not going to have weird races in really weird cases
      where a lot of different CRTCs are doing rendering and modesets at the
      same time.

      With this change and the stolen_lock from the previous patch, we can

      patches.

      v2:
       - Rebase (6 months later)
       - Also lock debugfs and stolen.
      v3:
       - Don't lock a single value read (Chris).
       - Replace lockdep assertions with WARNs (Daniel).
       - Improve commit message.
       - Don't forget intel_pre_plane_update() locking.
      v4:

       - Add comment regarding locking dependencies (Chris).
       - Rebase after the stolen code rework.
       - Rebase again after drm-intel-nightly changes.

       - Rebase after the new stolen_lock patch.

      drm/i915: add dev_priv->mm.stolen_lock

      Which should protect dev_priv->mm.stolen usage. This will allow us to

      v2:
        - Rebase after the stolen_remove_node() dev_priv patch move.
        - I realized that after we fixed a few things related to the FBC CFB
          size checks, we're not reallocating the CFB anymore with FBC
          enabled, so we can just move all the locking to i915_gem_stolen.c
          and stop worrying about freezing all the stolen alocations while
          freeing/rellocating the CFB. This allows us to fix the "Too

      drm/i915: add simple wrappers for stolen node insertion/removal

      We want to move the FBC code out of i915_gem_stolen.c, but that code
      directly adds/removes stolen memory nodes. Let's create this
      abstraction, so i915_gme_stolen.c is still in control of all the
      stolen memory handling. The abstraction will also allow us to add
      locking assertions later.

      v2:
        - Add dev_priv as remove_node() argument since we'll need it later
          (Chris).

      locking/qrwlock: Better optimization for interrupt context readers

      The qrwlock is fair in the process context, but becoming unfair when
      in the interrupt context to support use cases like the tasklist_lock.

      The current code isn't that well-documented on what happens when
      in the interrupt context. The rspin_until_writer_unlock() will only
      spin if the writer has gotten the lock. If the writer is still in the
      waiting state, the increment in the reader count will cause the writer
      to remain in the waiting state and the new interrupt context reader
      will get the lock and return immediately. The current code, however,
      does an additional read of the lock value which is not necessary as
      the information has already been there in the fast path. This may
      sometime cause an additional cacheline transfer when the lock is
      highly contended.

      This patch passes the lock value information gotten in the fast path
      to the slow path to eliminate the additional read. It also documents
      the action for the interrupt context readers more clearly.

      If the option -T is used with option --per-thread, then time is still

      perf trace: Use event filters for the event qualifier list

      We use raw_syscalls:sys_{enter,exit} events to show the syscalls, but were
      using a rather lazy/inneficient way to implement our 'strace -e' 
equivalent:
      filter out after reading the events in the ring buffer.

      Deflect more work to the kernel by appending a filter expression for that,
      that, together with the pid list, that is always present, if only to 
filter the
      tracer itself, reduces pressure on the ring buffer and otherwise use
      infrastructure already in place in the kernel to do early filtering.

      If we use it with -v we can see the filter passed to the kernel,
      for instance, for this contrieved case:

        # trace -v -e 
\!open,close,write,poll,recvfrom,select,recvmsg,writev,sendmsg,read,futex,epoll_wait,ioctl,eventfd

      perf evlist: Make perf_evlist__set_filter use perf_evsel__set_filter

      Instead of calling perf_evsel__apply_filter straight away, so that
      we can, in the next patches, expand the filter with more conditions
      before actually calling the ioctl to pass the end result filter to
      the kernel.

      Now we need to call perf_evlist__apply_filters() after the filter
      is completely setup, i.e. do the ioctl calls.

      The perf_evlist__apply_filters() method was already in place, because
      that is the model for the other tools that receives filters in the
      command line: go on setting then in the evsel->filter and only at
      the end, after parsing the whole command line, apply them.

      We get, as a bonus, a more expressive message that states which
      event, if any, failed to have the filter applied to, with an
      error message stating what happened.

      perf evsel: Rename set_filter to apply_filter

      We need to be able to go on constructing a complex filter in multiple
      stages, since we can only set one filter per event.

      For instance, we need to be able, in 'perf trace' to filter by the
      'common_pid' field all the time, if only for the tracer itself, to
      avoid a feedback loop, and, in addition, we may want to filter the
      raw_syscalls:sys_{enter,exit} events by its 'id' filter, when using
      'perf trace -e open,close' or 'perf trace -e !open,close', i.e. when
      we are interested in just a subset of syscalls or when we are not
      interested in it.

      So we will have:

         perf_evsel__set_filter(evsel, char *filter)

             Replaces whatever is in evsel->filter.

         perf_evsel__append_filter(evsel, const char *op, char *filter)

             Appends, using op ("&&" or "||") with what is in evsel->filter.

         perf_evsel__apply_filter(evsel, filter):

              That actually applies a filter, be it the one being
              constructed in evsel->filter, or any other, for tools
              with more specific ways to build the filter, issuing
              the appropriate ioctl for all the evsel fds.

      The same changes will be made to the evlist__{set,apply} variants to
      keep everything consistent.

      The runtime pm resume/suspend will enable/disable pclk (ISI peripheral
      clock).

      We have to call runtime_pm_get_sync()/runtime_pm_put() when we need to
      access ISI registers. In atmel_isi_probe(), remove the isi disable code
      as at that moment ISI peripheral clock is not enable yet.

      Besides, clock_start()/clock_stop() is used to control the mclk, not
      the ISI peripheral clock. So move this to start[stop]_streaming()

      [media] atmel-isi: disable ISI even if it has codec request

      In current code, stop_streaming() will just return if ISI is still
      working in the codec. But this is incorrect, we need to disable ISI even
      it is working on the codec, otherwise stop_streaming() will not work as
      we expected.

      [media] v4l: omap3isp: Fix sub-device power management code

      Commit 813f5c0ac5cc ("media: Change media device link_notify behaviour")
      modified the media controller link setup notification API and updated the
      OMAP3 ISP driver accordingly. As a side effect it introduced a bug by
      turning power on after setting the link instead of before. This results in
      sub-devices not being powered down in some cases when they should be. Fix
      it.

      The async notifier was registered before the v4l2_device was registered 
and
      before the notifier callbacks were set. This could lead to missing the
      bound() and complete() callbacks and to attempting to spin_lock() and
      uninitialised spin lock.

      Also fix unregistering the async notifier in the case of an error --- the
      function may not fail anymore after the notifier is registered.

      [media] v4l2-dv-timings: add support for reduced blanking v2

      Added support for reduced blanking version 2 (RB v2) in cvt timings.
      Standard specifies a fixed vsync pulse of 8 lines to indicate RB v2
      timings. Vertical back porch is fixed at 6 lines and vertical front
      porch is remainder of vertical blanking time.

      For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync
      is fixed at 32. All horizontal timing counts (active pixels, front,
      back porches) can be specified upto a precision of 1.

      RB v2 allows for non standard aspect ratios. In RB v2 vsync does not
      indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt()
      cannot calculate image width from image height. Hence extending the
      v4l2_detect_cvt() to pass image width in case of RB v2.

      gpio: make flags mandatory for gpiod_get functions

      Now that all[1] users of the gpiod_get functions are converted to make
      use of the up to now optional flags parameter, make it mandatory which
      allows to remove some cpp magic.

      [1] all but etraxfs-uart which is broken anyhow and I'm allowed to

      The current documention mentions explicitly that EINVAL should be
      returned if the device is not available, but nx842_OF_upd_status()
      always returns 0. However, nx842_probe() specifically checks for
      non-ENODEV returns from nx842_of_upd() (which in turn calls
      nx842_OF_upd_status()) and emits an extra error in that case. It seems
      like the proper return code of a disabled device is ENODEV.

      drm/i915: Account for CHV/BXT DPLL clock limitations

      CHV/BXT DPLL can't generate frequencies in the 216-240 MHz range.
      Account for that when checking whether the HDMI port clock is valid.
      This is particularly important for BXT since it can otherwise do
      12bpc, and standard 1920x1080p60 CEA modes land right in the middle
      of that range when the clock gets multiplied to account for 12bpc.

      With the extra checks we will now filter out any mode where both
      8bpc and 12bpc clock are within the gap. During modeset we then
      pick whichever mode works, favoring 12bpc if both are possible.

      12bpc isn't supported on CHV so we simply end up filtering out any
      mode where the 8bpc port clock is in the gap.

      ARM: shmobile: R-Car: Get rid of on_off_fn() function pointer

      Simplify the power request code by passing an "on" flag, and picking the
      right status bit and register offset in the innermost function, based on
      this flag.
      This allows to remove the rcar_sysc_pwr_{off,on}() helper functions, and
      the function pointer through which they were called.

      Make sr_bit and reg_offs unsigned while we're at it.

      ARM: shmobile: R-Car: Break infinite loop

      rcar_sysc_update() loops (with interrupts disabled and while holding a
      spinlock) until submitting a power shutoff or resume request fails, or
      until the submitted request was accepted.
      If none of these conditions becomes true, this forms an infinite loop.

      Put a limit on the maximum number of loop iterations, and add a small
      delay to each iteration, to fix this.

      ARM: shmobile: R-Car: Shrink rcar_sysc_ch size

      Shrink the individual fields in struct rcar_sysc_ch, as unsigned long or
      int is overkill:
        - chan_offs contains a register offset relative to a base value
          (< 512),
        - chan_bit and isr_bit contain bit indices (0-31).

      This reduces the size of each instance from 3 (4 on 64-bit) 32-bit words
      to 1 32-bit word.

      The KZM-A9-GT board is sufficiently supported by DT-based and board-less
      SH-Mobile AG5 (sh73a0) multiplatform kernels. Hence remove the legacy

      Lacking areas are:
        - USB (it does't work in legacy, neither),
        - LCDC (the LCDC is wired to the legacy INTC, which is not planned to

      ARM: shmobile: r8a7779: Remove GENPD_FLAG_PM_CLK flag

      The R-Car SYSC PM Domain only manages power domains for the main CPUs
      and for coprocessors. It does not fill in the genpd .{at,de}tach_dev()
      callbacks, and no power management clocks are registered for devices.
      Hence pm_clk_{suspend,resume}() are no-ops, and setting of the
      GENPD_FLAG_PM_CLK flag can be removed.

      Originally the clock handling was copied from the R-Mobile PM Domain
      code, which does manage a clock domain, in addition to device power
      domains.

      ARM: rockchip: fix the CPU soft reset

      We need different orderings when turning a core on and turning a core
      off.  In one case we need to assert reset before turning power off.
      In ther other case we need to turn power on and the deassert reset.

      In general, the correct flow is:

      CPU off:
          reset_control_assert
          regmap_update_bits(pmu, PMU_PWRDN_CON, BIT(pd), BIT(pd))
          wait_for_power_domain_to_turn_off
      CPU on:
          regmap_update_bits(pmu, PMU_PWRDN_CON, BIT(pd), 0)
          wait_for_power_domain_to_turn_on
          reset_control_deassert

      This is needed for stressing CPU up/down, as per:
          cd /sys/devices/system/cpu/
          for i in $(seq 10000); do
              echo "================= $i ============"
              for j in $(seq 100); do
                  while [[ "$(cat cpu1/online)$(cat cpu2/online)$(cat 
cpu3/online)" != "000"" ]]
                      echo 0 > cpu1/online
                      echo 0 > cpu2/online
                      echo 0 > cpu3/online
                  done
                  while [[ "$(cat cpu1/online)$(cat cpu2/online)$(cat 
cpu3/online)" != "111" ]]; do
                      echo 1 > cpu1/online
                      echo 1 > cpu2/online
                      echo 1 > cpu3/online
                  done
              done
          done

      The following is reproducable log:

          <hang>

          Tested by cpu up/down scripts, the results told us need delay more 
time
      before write the sram. The wait time is affected by many aspects
      (e.g: cpu frequency, bootrom frequency, sram frequency, bus speed, ...).

          Although the cpus other than cpu0 will write the sram, the speedy is
      no the same as cpu0, if the cpu0 early wake up, perhaps the other cpus
      can't startup. As we know, the cpu0 can wake up when the cpu1/2/3 write
      the 'sram+4/8' and send the sev.
          Anyway.....
          At the moment, 1ms delay will be happy work for cpu up/down scripts 
test.

      ARM: rockchip: restore dapswjdp after suspend

      In the commit (0ea001d ARM: rockchip: disable dapswjdp during suspend)
      we made the assumption that we didn't need to restore dapswjdp after
      suspend because "the MASKROM will enable it back".

      It turns out that's not a safe assumption.  In some cases (pending
      interrupts) it's possible that the WFI might act as a no-op and the
      MaskROM will never run.  Since we're changing the bit, we should
      restore it ourselves.

      drm: remove redundant code form drm_ioc32.c

      The compat ioctl handler ends up calling access_ok() twice: first
      indirectly inside compat_alloc_user_space() and then after returning
      from that function. This patch fixes issue.

      v2: there were three invalid removals of access_ok() that I've fixed.
      Also went through all the changes couple of times and verified that
      access_ok() is only removed when the buffer is allocated with
      compat_alloc_user_space(). My deepest apologies for this kind of
      sloppiness!

          drm/crtc_helper: Replace open-coded CRTC state helpers

      error handling code was broken, resulting in the first path not being
      checked correctly. Fix this by using the same pattern as in the

      v2: Simplify the cleanup code while at it too.

      v3: After some debugging with John we realized that the above patch
      from Daniel also accidentally removed the if (crtc_state) check. This
      is legal when transitioning to atomic, when the initial state reset
      isn't all wired up yet properly. Reinstate that check to fix the bug
      John has hit.

      drm/i915: Reserve space improvements

      An earlier patch was added to reserve space in the ring buffer for the
      commands issued during 'add_request()'. The initial version was
      pessimistic in the way it handled buffer wrapping and would cause
      premature wraps and thus waste ring space.

      This patch updates the code to better handle the wrap case. It no
      longer enforces that the space being asked for and the reserved space
      are a single contiguous block. Instead, it allows the reserve to be on
      the far end of a wrap operation. It still guarantees that the space is
      available so when the wrap occurs, no wait will happen. Thus the wrap
      cannot fail which is the whole point of the exercise.

      Also fixed a merge failure with some comments from the original patch.

      v2: Incorporated suggestion by David Gordon to move the wrap code
      inside the prepare function and thus allow a single combined
      wait_for_space() call rather than doing one before the wrap and
      another after. This also makes the prepare code much simpler and
      easier to follow.

      v3: Fix for 'effective_size' vs 'size' during ring buffer remainder
      calculations (spotted by Tomas Elf).

      drm: Reject DRI1 hw lock ioctl functions for kms drivers

      I've done some extensive history digging across libdrm, mesa and
      xf86-video-{intel,nouveau,ati}. The only potential user of this with
      kms drivers I could find was ttmtest, which once used drmGetLock
      still. But that mistake was quickly fixed up. Even the intel xvmc
      library (which otherwise was really good with using dri1 stuff in kms
      mode) managed to never take the hw lock for dri2 (and hence kms).

      Hence it should be save to unconditionally disallow this.

      ath10k: configure frag desc memory to target for qca99X0

      Pre qca99X0 chipsets follows the model where dynamically allocate
      memory for frag desc on getting new skb for TX. But, this is not
      going to be the case in qca99X0. It expects frag desc memory to be
      allocated at boot time and let the driver to reuse allocated memory
      after every TX completion. So there won't be any dynamic frag memory
      memory allocation in qca99X0 during data transmission.

      qca99X0 hardware doesn't need fragment desc address to be programmed
      in msdu descriptor for every data transaction. It needs to know only
      starting address of fragment descriptor at the time of the boot.
      During data transmission, qca99X0 hardware can retrieve corresponding
      frag addr by adding programmed frag desc base addr + msdu id.

      Allocate continuous fragment descriptor memory (same size as number of
      descriptor) at the time of target initialization and configure allocated
      dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.

      How this is allocated continuous memory is going to be used is not
      covered in this patch. It just allocates memory and hand over to firmware.
      If we don't do it at init time, qca99X0 will stall when firmware tries
      to do TX.

      ath10k: handle 10.4 firmware wmi swba event

      10.4 firmware swba event payload has space to accommodate upto
      512 client traffic indication info & one p2p noa descriptor.
      It's is not matching with exiting swba event format defined for
      non 10.4 firmware. Non 10.4 firmware swba event format is designed
      to support only upto only 128 client and four p2p notice of absence
      descriptor.

      following changes are done in this patch to enable ath10k to handle
      10.4 firmware swba event,

       - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
         event in 10.4 wmi rx handler.

       - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

       - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
         10.4 swba event.

       - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
         power save state.

      ath10k: enhance swba event handler to adapt different size tim bitmap

      Due to 512 client support in 10.4 firmware, size of tim ie is going
      to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
      what is carried in swba event from 10.4 firmware is bit higher.

      The only bottle neck to reuse existing swba handler
      ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
      with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
      This patch removes such size limitation and makes it more suitable
      to handle swba event which has different size tim bitmap.

      All existing swba event parsing functions are changed to adapt this
      change. Actual support to handle 10.4 swba event is added in next patch.
      Only preparation is made in this patch.

      ath: DFS - limit number of potential PRI sequences

      In the PRI detector, after the current radar pulse
      has been checked agains existing PRI sequences, it
      is considered as part of a new potential sequence.

      Previously, the condition to accept a new sequence
      was to have at least the same number of pulses as
      the longest matching sequence. This was wrong,
      since it led to duplicates of PRI sequences.

      This patch changes the acceptance criteria for new
      potential sequences from 'at least' to 'more than'
      the longest existing.

      Detection performance remains unaffected, while
      the number of PRI sequences accounted at runtime
      (and with it CPU load) is reduced by up to 50%.

      Depending on the platform the port clock fed to the pipe can be the PLL's
      post-divided fast clock rate or a /5 divided version of it. To make this
      more obvious across the platforms calculate this port clock along with
      the rest of the PLL parameters.

      This is also needed by the next patch where we can reuse the CHV helper
      for the BXT PLL HW readout code; so export the corresponding helper.

      While at it also add a more descriptive name to the helpers and a

      drm/i915: Zero unused WM1 watermarks on VLV/CHV

      The hardware supposedly ignores the WM1 watermarks while the PND
      deadline mode is enabled, but clear out the register just in case.
      This is what the other OS does, and it does make register dumps look
      more consistent when we don't have partial WM1 values lingering in
      the registers (some WM1 watermarks already get zeroed when the actually
      used DSPFW registers get written).

      drm/i915: Try to make sure cxsr is disabled around plane enable/disable

      CxSR (or maxfifo on VLV/CHV) blocks somne changes to the plane control
      register (enable bit at least, not quite sure about the rest). So in
      order to have the plane enable/disable when we want we need to first
      kick the hardware out of cxsr.

      Unfortunateloy this requires some extra vblank waits. For the CxSR
      enable after the plane update we should eventually use an async
      vblank worker, but since we don't have that just do sync vblank
      waits. For the disable case we have no choice but to do it
      synchronously.

      drm/i915: Use the memory latency based WM computation on VLV too

      In order to get decnet memory self refresh residency on VLV, flip it
      over to the new CHV way of doing things. VLV doesn't do PM5 or DDR DVFS
      so it's a bit simpler.

      I'm not sure the currently memory latency used for CHV is really
      appropriate for VLV. Some further testing will probably be needed to
      figure that out.

      drm/i915: Compute display FIFO split dynamically for CHV

      Consider which planes are active and compute the FIFO split based on the
      relative data rates. Since we only consider the pipe src width rather
      than the plane width when computing watermarks it seems best to do the
      same when computing the FIFO split as well. This means the only thing we
      actually have to consider for the FIFO splut is the bpp, and we can
      ignore the rest.

      I've just stuffed the logic into the watermark code for now. Eventually
      it'll need to move into the atomic update for the crtc.

      There's also one extra complication I've not yet considered; Some of the
      DSPARB registers contain bits related to multiple pipes. The registers
      are double buffered but apparently they update on the vblank of any
      active pipe. So doing the FIFO reconfiguration properly when multiple
      pipes are active is not going to be fun. But let's ignore that mess for
      now.

      drm/i915: CHV DDR DVFS support and another watermark rewrite

      Turns out the VLV/CHV system agent doesn't understand memory
      latencies, so trying to rely on the PND deadline mechanism is not
      going to fly especially when DDR DVFS is enabled. Currently we try to
      avoid the problems by lying to the system agent about the deadlines
      and setting the FIFO watermarks to 8 cachelines. This however leads to
      bad memory self refresh residency.

      So in order to satosfy everyone we'll just give up on the deadline
      scheme and program the watermarks old school based on the worst case
      memory latency.

      I've modelled this a bit on the ILK+ approach where we compute multiple
      sets of watermarks for each pipe (PM2,PM5,DDR DVFS) and when merge thet
      appropriate one later with the watermarks from other pipes. There isn't
      too much to merge actually since each pipe has a totally independent
      FIFO (well apart from the mess with the partially shared DSPARB
      registers), but still decopuling the pipes from each other seems like a
      good idea.

      Eventually we'll want to perform the watermark update in two phases
      around the plane update to avoid underruns due to the single buffered
      watermark registers. But that's still in limbo for ILK+ too, so I've not
      gone that far yet for VLV/CHV either.

      However a shortcut path on update primary plane function
      to make primary plane invisible by setting DSPCTRL to 0
      was leting IPS enabled while there was no
      other plane enabled on the pipe causing flickerings that we were

      drm/i915/skl: Replace the HDMI DPLL divider computation algorithm

      The HW validation team came back from further testing with a slightly
      changed constraint on the deviation between the DCO frequency and the
      central frequency. Instead of +-4%, it's now +1%/-6%.

      Unfortunately, the previous algorithm didn't quite cope with these new
      constraints, the reason being that it wasn't thorough enough looking at
      the possible divider candidates.

      The new algorithm looks at all dividers, which is definitely a hammer
      approach (we could reduce further the set of dividers to good ones as a
      follow up, at the cost of a bit more complicated code). But, at least,
      we can now satisfy the +1%/+6% rule for all the "Well known" HDMI
      frequencies of my test set (373 entries).

      On that subject, the new code is quite extensively tested in
      intel-gpu-tools (tools/skl_compute_wrpll).

      v2: Fix cycling between central frequencies and dividers (Paulo)
          Properly choose the minimal deviation between postive and negative
          candidates (Paulo).

          On the 373 test frequencies, v2 computes better dividers than v1 (ie
          more even dividers and lower deviation on average):

          v1: average deviation: 206.52
          v2: average deviation: 194.47

      drm/i915/gtt: Pin vma during virtual address allocation

      Dynamic page table allocation might wake the shrinker
      when memory is requested for page table structures.
      As this happens when we try to allocate the virtual address
      during binding, our vma might be among the targets for eviction.
      We should do i915_vma_pin() and do pin early in there like Chris
      suggests but this is interim solution.

      Shield our vma from shrinker by incrementing pin count before
      the virtual address is allocated.

      The proper place to fix this would be in gem, inside of
      i915_vma_pin(). But we don't have that yet so take the short
      cut as a intermediate solution.

      drm/i915/drrs: Restrict buffer tracking to the DRRS pipe

      The current code tracks business across all pipes, but we're only
      really interested in the one pipe DRRS is enabled on. Fairly tiny
      optimization, but something I noticed while reading the code. But it
      might matter a bit when e.g. showing a video or something only on the
      external screen, while the panel is kept static.

      Also regroup the code slightly: First compute new bitmasks, then take
      appropriate actions.

      drm/i915: s/update/compute/ for gmch dpll register functions

      I was momentarily confused until I've double-checked that these
      functions really only compute state and don't update the hardware
      state. They once did that, but since Ander's rework of the dpll
      computation flow that's no longer the case.

      Rename them to avoid further confusion.

      Note that the ilk code already follows the compute_dpll naming scheme
      for computing the actual register value. DDI code goes with _calc_,
      but that is close enough.

      drm/i915: Clear fb_tracking.busy_bits also for synchronous flips

      The current/old frontbuffer might still have gpu frontbuffer rendering
      pending. But once flipped it won't have the corresponding frontbuffer
      bits any more and hence the request retire function won't ever clear
      the corresponding busy bits. The async flip tracking (with the
      flip_prepare and flip_complete functions) already does this, but
      somehow I've forgotten to do this for synchronous flips.

      Note that we don't track outstanding rendering of the new framebuffer
      with busy_bits since all our plane update code waits for previous
      rendering to complete before displaying a new buffer. Hence a new
      buffer will never be busy.

      v2: Drop the spurious inline Ville spotted.

      v3: Don't touch flip_bits in the synchronsou frontbuffer_flip
      function, noticed by Paulo.

      v4: Remove one more inline that slipped through (Paulo).

      drm/i915: Update a bunch of LRC functions to take requests

      A bunch of the low level LRC functions were passing around ringbuf and ctx
      pairs. In a few cases, they took the r/c pair and a request as well. This 
is all
      quite messy and unnecesary. The context_queue() call is especially bad 
since the
      fake request code got removed - it takes a request and three extra things 
that
      must be extracted from the request and then it checks them against what 
it finds
      in the request. Removing all the derivable data makes the code much 
simpler all
      round.

      This patch updates those functions to just take the request structure.

      Note that logical_ring_wait_for_space now takes a request structure but 
already
      had a local request pointer that it uses to scan for something to wait 
on. To
      avoid confusion the local variable has been renamed 'target' (it is 
searching
      for a target request to do something with) and the parameter has been 
called req
      (to guarantee anything accidentally missed gets a compiler error).

      v2: Updated commit message re wait_for_space (Tomas Elf review comment).

      drm/i915: Remove 'faked' request from LRC submission

      The LRC submission code requires a request for tracking purposes. It does 
not
      actually require that request to 'complete' it simply uses it for keeping 
hold
      of reference counts on contexts and such like.

      Previously, the fall back path of polling for space in the ring would 
start by
      submitting any outstanding work that was sat in the buffer. This 
submission was
      not done as part of the request that that work was owned by because that 
would
      lead to complications with the request being submitted twice. Instead, a 
null
      request structure was passed in to the submit call and a fake one was 
created.

      That fall back path has long since been obsoleted and has now been 
removed. Thus
      there is never any need to fake up a request structure. This patch 
removes that
      code. A couple of sanity check warnings are added as well, just in case.

      drm/i915: Move the request/file and request/pid association to creation 
time

      In _i915_add_request(), the request is associated with a userland client.
      Specifically it is linked to the 'file' structure and the current user 
process
      is recorded. One problem here is that the current user process is not
      necessarily the same as when the request was submitted to the driver. 
This is
      especially true when the GPU scheduler arrives and decouples driver 
submission
      from hardware submission. Note also that it is only in the case where the 
add
      request comes from an execbuff call that there is a client to associate. 
Any
      other add request call is kernel only so does not need to do it.

      This patch moves the client association into a separate function. This is 
then
      called from the execbuffer code path itself at a sensible time. It also 
removes
      the now redundant 'file' pointer from the add request parameter list.

      An extra cleanup of the client association is also added to the request 
clean up
      code for the eventuality where the request is killed after association but
      before being submitted (e.g. due to out of memory error somewhere). Once 
the
      submission has happened, the request is on the request list and the 
regular
      request list removal will clear the association. Note that this still 
needs to
      happen at this point in time because the request might be kept floating 
around
      much longer (due to someone holding a reference count) and the client 
should not
      be worrying about this request after it has been retired.

      drm/i915: Update queue_flip() to take a request structure

      Updated the display page flip code to do explicit request creation and
      submission rather than relying on the OLR and just hoping that the request
      actually gets submitted at some random point.

      The sequence is now to create a request, queue the work to the ring, 
assign the
      known request to the flip queue work item then actually submit the work 
and post
      the request.

      Note that every single flip function used to finish with
      '__intel_ring_advance(ring);'. However, immediately after they return 
there is
      now an add request call which will do the advance anyway. Thus the many
      duplicate advance calls have been removed.

      v2: Updated commit message with comment about advance removal.

      v3: The request can now be allocated by the _sync() code earlier on. Thus 
the
      page flip path does not necessarily need to allocate a new request, it 
may be
      able to re-use one.

      drm/i915: Update i915_gem_object_sync() to take a request structure

      The plan is to pass requests around as the basic submission tracking 
structure
      rather than rings and contexts. This patch updates the 
i915_gem_object_sync()
      code path.

      v2: Much more complex patch to share a single request between the sync 
and the
      page flip. The _sync() function now supports lazy allocation of the 
request
      structure. That is, if one is passed in then that will be used. If one is 
not,
      then a request will be allocated and passed back out. Note that the 
_sync() code
      does not necessarily require a request. Thus one will only be created 
until
      certain situations. The reason the lazy allocation must be done within the
      _sync() code itself is because the decision to need one or not is not 
really
      something that code above can second guess (except in the case where one 
is
      definitely not required because no ring is passed in).

      The call chains above _sync() now support passing a request through which 
most
      callers passing in NULL and assuming that no request will be required 
(because
      they also pass in NULL for the ring and therefore can't be generating any 
ring
      code).

      The exeception is intel_crtc_page_flip() which now supports having a 
request
      returned from _sync(). If one is, then that request is shared by the page 
flip
      (if the page flip is of a type to need a request). If _sync() does not 
generate
      a request but the page flip does need one, then the page flip path will 
create
      its own request.

      v3: Updated comment description to be clearer about 'to_req' parameter 
(Tomas
      Elf review request). Rebased onto newer tree that significantly changed 
the
      synchronisation code.

      v4: Updated comments from review feedback (Tomas Elf)

      drm/i915: Update deferred context creation to do explicit request 
management

      In execlist mode, context initialisation is deferred until first use of 
the
      given context. This is because execlist mode has per ring context state 
and thus
      many more context storage objects than legacy mode and many are never 
actually
      used. Previously, the initialisation commands were written to the ring and
      tagged with some random request structure via the OLR. This seemed to be 
causing
      a null pointer deference bug under certain circumstances (BZ:88865).

      This patch adds explicit request creation and submission to the deferred
      initialisation code path. Thus removing any reliance on or randomness 
caused by
      the OLR.

      Note that it should be possible to move the deferred context creation 
until even
      later - when the context is actually switched to rather than when it is 
merely
      validated. This would allow the initialisation to be done within the 
request of
      the work that is wanting to use the context. Hence, the extra request 
that is
      created, used and retired just for the context init could be removed 
completely.
      However, this is left for a follow up patch.

      switch's context. As the context switch now gets the context object from 
the

      drm/i915: Don't tag kernel batches as user batches

      The render state initialisation code does an explicit i915_add_request() 
call to
      commit the init commands. It was passing in the initialisation batch 
buffer to
      add_request() as the batch object parameter. However, the batch object 
entry in
      the request structure (which is all that parameter is used for) is meant 
for
      keeping track of user generated batch buffers for blame tagging during GPU
      hangs.

      This patch clears the batch object parameter so that kernel generated 
batch
      buffers are not tagged as being user generated.

      drm/i915: Split i915_ppgtt_init_hw() in half - generic and per ring

      The i915_gem_init_hw() function calls a bunch of smaller initialisation
      functions. Multiple of which have generic sections and per ring sections. 
This
      means multiple passes are done over the rings. Each pass writes data to 
the ring
      which floats around in that ring's OLR until some random point in the 
future
      when an add_request() is done by some random other piece of code.

      This patch breaks i915_ppgtt_init_hw() in two with the per ring 
initialisation
      now being done in i915_ppgtt_init_ring(). The ring looping is now done at

      drm/i915: Add request to execbuf params and add explicit cleanup

      Rather than just having a local request variable in the execbuff code, the
      request pointer is now stored in the execbuff params structure. Also added
      explicit cleanup of the request (plus wiping the OLR to match) in the 
error
      case. This means that the execbuff code is no longer dependent upon the 
OLR
      keeping track of the request so as to not leak it when things do go 
wrong. Note
      that in the success case, the i915_add_request() at the end of the 
submission
      function will tidy up the request and clear the OLR.

      drm/i915: Merged the many do_execbuf() parameters into a structure

      The do_execbuf() function takes quite a few parameters. The actual set of
      parameters is going to change with the conversion to passing requests 
around.
      Further, it is due to grow massively with the arrival of the GPU 
scheduler.

      This patch simplifies the prototype by passing a parameter structure 
instead.
      Changing the parameter set in the future is then simply a matter of
      adding/removing items to the structure.

      Note that the structure does not contain absolutely everything that is 
passed
      in. This is because the intention is to use this structure more 
extensively
      later in this patch series and more especially in the GPU scheduler that 
is
      coming soon. The latter requires hanging on to the structure as the final
      hardware submission can be delayed until long after the execbuf IOCTL has
      returned to user land. Thus it is unsafe to put anything in the structure 
that
      is local to the IOCTL call itself - such as the 'args' parameter. All 
entries
      must be copies of data or pointers to structures that are reference 
counted in
      some way and guaranteed to exist for the duration of the batch buffer's 
life.

      v2: Rebased to newer tree and updated for changes to the command parser.
      Specifically, a code shuffle has required saving the batch start address 
in the
      params structure.

      drm/i915: Set context in request from creation even in legacy mode

      In execlist mode, the context object pointer is written in to the request
      structure (and reference counted) at the point of request creation. In 
legacy
      mode, this only happens inside i915_add_request().

      This patch updates the legacy code path to match the execlist version. 
This
      allows all the intermediate code between request creation and request 
submission
      to get at the context object given only a request structure. Thus 
negating the
      need to pass context pointers here, there and everywhere.

      v2: Moved the context reference so it does not need to be undone if the
      get_seqno() fails.

      v3: Fixed execlist mode always hitting a warning about invalid 
last_contexts
      (which don't exist in execlist mode).

      Start of explicit request management in the execbuffer code path. This 
patch
      adds a call to allocate a request structure before all the actual 
hardware work
      is done. Thus guaranteeing that all that work is tagged by a known 
request. At
      present, nothing further is done with the request, the rest comes later 
in the
      series.

      The only noticable change is that failure to get a request (e.g. due to 
lack of
      memory) will be caught earlier in the sequence. It now occurs right at 
the start
      before any un-undoable work has been done.

      drm/i915: i915_add_request must not fail

      The i915_add_request() function is called to keep track of work that has 
been
      written to the ring buffer. It adds epilogue commands to track progress 
(seqno
      updates and such), moves the request structure onto the right list and 
other
      such house keeping tasks. However, the work itself has already been 
written to
      the ring and will get executed whether or not the add request call 
succeeds. So
      no matter what goes wrong, there isn't a whole lot of point in failing 
the call.

      At the moment, this is fine(ish). If the add request does bail early on 
and not
      do the housekeeping, the request will still float around in the
      ring->outstanding_lazy_request field and be picked up next time. It means
      multiple pieces of work will be tagged as the same request and driver 
can't
      actually wait for the first piece of work until something else has been
      submitted. But it all sort of hangs together.

      This patch series is all about removing the OLR and guaranteeing that 
each piece
      of work gets its own personal request. That means that there is no more
      'hoovering up of forgotten requests'. If the request does not get tracked 
then
      it will be leaked. Thus the add request call _must_ not fail. The 
previous patch
      should have already ensured that it _will_ not fail by removing the 
potential
      for running out of ring space. This patch enforces the rule by actually 
removing
      the early exit paths and the return code.

      Note that if something does manage to fail and the epilogue commands 
don't get
      written to the ring, the driver will still hang together. The request 
will be
      added to the tracking lists. And as in the old case, any subsequent work 
will
      generate a new seqno which will suffice for marking the old one as 
complete.

      v2: Improved WARNings (Tomas Elf review request).

      drm/i915: Reserve ring buffer space for i915_add_request() commands

      It is a bad idea for i915_add_request() to fail. The work will already 
have been
      send to the ring and will be processed, but there will not be any 
tracking or
      management of that work.

      The only way the add request call can fail is if it can't write its 
epilogue
      commands to the ring (cache flushing, seqno updates, interrupt 
signalling). The
      reasons for that are mostly down to running out of ring buffer space and 
the
      problems associated with trying to get some more. This patch prevents that
      situation from happening in the first place.

      When a request is created, it marks sufficient space as reserved for the
      epilogue commands. Thus guaranteeing that by the time the epilogue is 
written,
      there will be plenty of space for it. Note that a ring_begin() call is 
required
      to actually reserve the space (and do any potential waiting). However, 
that is
      not currently done at request creation time. This is because the 
ring_begin()
      code can allocate a request. Hence calling begin() from the request 
allocation
      code would lead to infinite recursion! Later patches in this series 
remove the
      need for begin() to do the allocate. At that point, it becomes safe for 
the
      allocate to call begin() and really reserve the space.

      Until then, there is a potential for insufficient space to be available 
at the
      point of calling i915_add_request(). However, that would only be in the 
case
      where the request was created and immediately submitted without ever 
calling
      ring_begin() and adding any work to that request. Which should never 
happen. And
      even if it does, and if that request happens to fall down the tiny window 
of
      opportunity for failing due to being out of ring space then does it really
      matter because the request wasn't doing anything in the first place?

      v2: Updated the 'reserved space too small' warning to include the 
offending
      sizes. Added a 'cancel' operation to clean up when a request is 
abandoned. Added
      re-initialisation of tracking state after a buffer wrap to keep the sanity
      checks accurate.

      v3: Incremented the reserved size to accommodate Ironlake (after finally
      managing to run on an ILK system). Also fixed missing wrap code in LRC 
mode.

      v4: Added extra comment and removed duplicate WARN (feedback from Tomas).

      drm/i915/gen8: Add infrastructure to initialize WA batch buffers

      Some of the WA are to be applied during context save but before restore 
and
      some at the end of context save/restore but before executing the 
instructions
      in the ring, WA batch buffers are created for this purpose and these WA 
cannot
      be applied using normal means. Each context has two registers to load the
      offsets of these batch buffers. If they are non-zero, HW understands that 
it
      need to execute these batches.

      v1: In this version two separate ring_buffer objects were used to load WA
      instructions for indirect and per context batch buffers and they were part
      of every context.

      v2: Chris suggested to include additional page in context and use it to 
load
      these WA instead of creating separate objects. This will simplify lot of 
things
      as we need not explicity pin/unpin them. Thomas Daniel further pointed 
that GuC
      is planning to use a similar setup to share data between GuC and driver 
and
      WA batch buffers can probably share that page. However after discussions 
with
      Dave who is implementing GuC changes, he suggested to use an independent 
page
      for the reasons - GuC area might grow and these WA are initialized only 
once and
      are not changed afterwards so we can share them share across all contexts.

      The page is updated with WA during render ring init. This has an 
advantage of
      not adding more special cases to default_context.

      We don't know upfront the number of WA we will applying using these batch 
buffers.
      For this reason the size was fixed earlier but it is not a good idea. To 
fix this,
      the functions that load instructions are modified to report the no of 
commands
      inserted and the size is now calculated after the batch is updated. A 
macro is
      introduced to add commands to these batch buffers which also checks for 
overflow
      and returns error.
      We have a full page dedicated for these WA so that should be sufficient 
for
      good number of WA, anything more means we have major issues.
      The list for Gen8 is small, same for Gen9 also, maybe few more gets added
      going forward but not close to filling entire page. Chris suggested a 
two-pass
      approach but we agreed to go with single page setup as it is a one-off 
routine
      and simpler code wins.

      One additional option is offset field which is helpful if we would like to
      have multiple batches at different offsets within the page and select them
      based on some criteria. This is not a requirement at this point but could
      help in future (Dave).

      Chris provided some helpful macros and suggestions which further 
simplified
      the code, they will also help in reducing code duplication when WA for
      other Gen are added. Add detailed comments explaining restrictions.
      Use do {} while(0) for wa_ctx_emit() macro.

      drm/i915: Remove KMS Kconfig option

      Since we only support modesetting by default (disabling modesetting on
      the command line prevents i915.ko from loading), having a parameter to
      disable modesstting by default is superfluous, i.e. saying
      CONFIG_DRM_I915_KMS=n is equivalent to CONFIG_DRM_I915=n.

      drm/i915: Ignore LVDS presence in VBT flag if the LVDS is enabled by BIOS

      On older gen, pre-Ironlake, parts there is no hardwired pin to report
      the presence of an LVDS panel. Instead, we have to rely on the VBT to
      declare whether the machine has a panel or not. Though notoriously
      unreliable, so far we have erred on the side of false-positives and have
      required a list of machines which end up falsely reporting a panel as
      present. However, we now have reports of false-negatives, machines with
      an LVDS that are being ignored due to the VBT not declaring the panel.
      This patch ignores the VBT setting if the BIOS has already enabled the
      LVDS panel (and on Ironlake+ we also have the hardware presence pin).

      It fixes the Samsung NP680Z5E-X01FR in the bug report, but is likely to
      result in more false-positives, and since we rely on the BIOS to enable
      the panel, there are likely different circumstances where the BIOS will
      not enable that panel (and so we may see the same machine with and
      without a panel all on the whim of the BIOS).

      drm/i915: atomic plane updates in a nutshell

      Now that all planes are added during a modeset we can use the
      calculated changes before disabling a plane, and then either commit
      or force disable a plane before disabling the crtc.

      The code is shared with atomic_begin/flush, except watermark updating
      and vblank evasion are not used.

      This is needed for proper atomic suspend/resume support.

      drm/i915: Handle disabling planes better, v2.

      Read out the initial state, and add a quirk to force add all planes
      to crtc_state->plane_mask during initial commit. This will disable

      The initial plane quirk is temporary, and will go away when hardware

      are removed.

      - Unset state->visible on !primary planes.
      - Do not rely on the plane->crtc pointer in intel_atomic_plane,
        instead assume planes are invisible until modeset.

      Grabbing crtc state from atomic state is a lot more involved,
      and make sure connectors are added before calling this function.

      Move check_digital_port_conflicts to intel_modeset_checks,
      it's only useful to check it on a modeset.

      iio: allow userspace to flush the hwfifo with non-blocking reads

      This patch changes the semantics of non-blocking reads so that a
      hardware fifo flush is triggered if the available data in the device
      buffer is less then the requested size.

      This allows userspace to accurately generate hardware fifo flushes, by
      doing a non-blocking read with a size greater then the sum of the
      device buffer and hardware fifo size.

      drm/i915: Reset request handling for gen8+

      In order for gen8+ hardware to guarantee that no context switch
      takes place during engine reset and that current context is properly
      saved, the driver needs to notify and query hw before commencing
      with reset.

      There are gpu hangs where the engine gets so stuck that it never will
      report to be ready for reset. We could proceed with reset anyway, but
      with some hangs with skl, the forced gpu reset will result in a system
      hang. By inspecting the unreadiness for reset seems to correlate with
      the probable system hang.

      We will only proceed with reset if all engines report that they
      are ready for reset. If root cause for system hang is found and
      can be worked around with another means, we can reconsider if
      we can reinstate full reset for unreadiness case.

      Enable VHT support for IBSS, while mac80211/cfg80211 and
      wpa_supplicant already support this.

      In my test env, qca988x 2x2 I get:

      (udp) ath10k-1 >>>> ath10k-2 (server) -  speed: 419 Mbits/sec
      (tcp) ath10k-1 >>>> ath10k-2 (server) -  speed: 404 Mbits/sec

      During tests I used wpa_supplicant (latest git version), which
      already support IBSS VHT, and choose highest available BW. Also tested 
with
      qca6174.

      drm/i915: Drop the 64k linear scanout alignment on gen2/3

      The docs don't support the 64k linear scanout alignment we impose
      on gen2/3. And it really makes no sense since we have no DSPSURF
      register, so the only thing that the hardware will see is the linear
      offset which will be just pixel aligned anyway.

      There is one case where 64k comes into the picture, and that's FBC.
      The start of the line length buffer corresponds to a 64k aligned
      address of the uncompressed framebuffer. So if the uncompressed fb is
      not 64k aligned, the first actually used entry in the line length
      buffer will not be byte 0. There are 32 extra entries in the line
      length buffer to account for this extra alignment so we shouldn't
      have to worry about it when mapping the uncompressed fb to the GTT.

      drm/i915: Align DSPSURF to 128k on VLV/CHV

      VLV/CHV have problems with 4k aligned linear scanout buffers. The VLV
      docs got updated at some point to say that we need to align them to
      128k, just like we do on gen4.

      So far I've seen the problem manifest when the stride is an odd multiple
      of 512 bytes, and the surface address meets the following pattern
      '(addr & 0xf000) == 0x1000' (also == 0x2000 is problematic on VLV). The
      result is a starcase effect (so some pages get dropped maybe?), with a
      few pages here and there clearly getting scannout out at the wrong 
position.

      I've not actually been able to reproduce this problem on gen4, so it's
      not clear of the issue is any way related to the 128k restrictions
      supposedly inherited from gen4. But let's hope the 128k alignment is
      sufficient to hide it all.

      drm/i915: Actually respect DSPSURF alignment restrictions

      Currently intel_gen4_compute_page_offset() simply picks the closest
      page boundary below the linear offset. That however may not be suitably
      aligned to satisfy any hardware specific restrictions. So let's make
      sure the page boundary we choose is properly aligned.

      Also to play it a bit safer lets split the remaining linear offset into
      x and y values instead of just x. This should make no difference for
      most platforms since we convert the x and y offsets back into a linear
      offset before feeding them to the hardware. HSW+ are different however
      and use x and y offsets even with linear buffers, so they might have
      trouble if either the x or y get too big.

      scripts/package/Makefile: rpmbuild is needed for rpm targets

      Before rpm release 4.1, in 2002, either the rpm command or the
      rpmbuild command could be used in the rpm-pkg or binrpm-pkg targets,
      and the Makefile chose the rpm command if the rpmbuild command wasn't
      found.

      After release 4.1, however, the rpm command could no longer be used in
      place of the rpmbuild command.  As the rpmbuild command is not
      installed by default, this can lead to failures with the rpm-pkg and
      binrpm-pkg targets:

      rpm --define "_builddir ." --target \
          x86_64 -bb ./binkernel.spec
          rpm --target: unknown option
          scripts/package/Makefile:60: recipe for target 'binrpm-pkg' failed

      Change the Makefile to use rpmbuild unconditionally to avoid this.

      Only bit 27 of SCRATCH1 and bit 6 of ROW_CHICKEN3 are allowed to be
      set because of security-sensitive bits we don't want userspace to mess
      with.  On HSW hardware the whitelisted bits control whether atomic
      read-modify-write operations are performed on L3 or on GTI, and when
      set to L3 (which can be 10x-30x better performing than on GTI,
      depending on the application) require great care to avoid a system
      hang, so we currently program them to be handled on GTI by default.

      Beignet can immediately start taking advantage of this change to
      enable L3 atomics.  Mesa should eventually switch to L3 atomics too,
      but a number of non-trivial changes are still required so it will
      continue using GTI atomics for now.

      drm/i915: Extend the parser to check register writes against a mask/value 
pair.

      In some cases it might be unnecessary or dangerous to give userspace
      the right to write arbitrary values to some register, even though it
      might be desirable to give it control of some of its bits.  This patch
      extends the register whitelist entries to contain a mask/value pair in
      addition to the register offset.  For registers with non-zero mask,
      any LRM writes and LRI writes where the bits of the immediate given by
      the mask don't match the specified value will be rejected.

      This will be used in my next patch to grant userspace partial write
      access to some sensitive registers.

      drm/i915: Fix command parser to validate multiple register access with 
the same command.

      Until now the software command checker assumed that commands could
      read or write at most a single register per packet.  This is not
      necessarily the case, MI_LOAD_REGISTER_IMM expects a variable-length
      list of offset/value pairs and writes them in sequence.  The previous
      code would only check whether the first entry was valid, effectively
      allowing userspace to write unrestricted registers of the MMIO space
      by sending a multi-register write with a legal first register, with
      potential security implications on Gen6 and 7 hardware.

      Fix it by extending the drm_i915_cmd_descriptor table to represent
      multi-register access and making validate_cmd() iterate for all
      register offsets present in the command packet.

      CHV. The spec lists both 31 and 63 as "suggested" values, but based on
      feedback from hardware folks we should actually be using 63. Originally
      I picked the 31 basically by flipping a coin.

      Fix resume from suspend on IBM X30

      This patch fixes the resume from suspend-to-ram on the IBM X30
      laptop. The problem is caused by the Bios missing to re-initialize
      the iVCH registers, especially the PLL registers.

      This patch records the iVCH registers during initialization, and
      re-installs this register set when resuming.

      drm/i915: Double the port clock when using double clocked modes with 12bpc

      Currently we're forgetting to double the port clock when using double
      clocked modes with 12bpc on HDMI. We're only accounting for the 1.5x
      factor due to the 12bpc. So further double the 1.5x port clock when we
      have a double clocked mode.

      Unfortunately I don't have any displays that support both 12bpc and
      double clocked modes, so I was unable to test this.

      Check that the DIP is enabled on the right port on IBX and VLV/CHV as

      drm/i915: Disable all infoframes when turning off the HDMI port

      Currently we just disable the GCP infoframe when turning off the port.
      That means if the same transcoder is used on a DP port next, we might
      end up pushing infoframes over DP, which isn't intended. Just disable
      all the infoframes when turning off the port.

      Also protect against two ports stomping on each other on g4x due to
      the single video DIP instance. Now only the first port to enable
      gets to send infoframes.

      Follow the procedure listed in Bspec to toggle the port enable bit off
      and on when enabling HDMI with 12bpc and pixel repeat on IBX. The old
      code didn't actually enable the port before "toggling" the bit back off,
      so the whole workaround was essentially a nop.

      Also take the opportunity to clarify the code by splitting the gmch
      platforms to a separate (much more straightforward) function.

      drm/i915: Send GCP infoframes for deep color HDMI sinks

      GCP infoframes are required to inform the HDMI sink about the color
      depth.

      Send the GCP infoframe whenever the sink supports any deep color modes
      since such sinks must anyway be capable of receiving them. For sinks
      that don't support deep color let's skip the GCP in case it might
      confuse the sink, although HDMI 1.4 spec does say all sinks must be
      capable of reciving them. In theory we could skip the GCP infoframe
      for deep color sinks in 8bpc mode as well since sinks must fall back to
      8bpc whenever GCP isn't received for some time.

      BSpec says we should disable GCP after disabling the port, so do that as
      well.

      aren't able to power-up the ADC, and rely in Linux doing it instead.

      This commit uses the adc-reserved-channels devicetree property to
      distinguish shared usage. In this case, the ADC is powered up at
      probe time.

      If the ADC is used only by the CPU running Linux, power-up/down
      at runtime, only when neeeded.

      drm/i915: get rid of intel_plane_restore in intel_crtc_page_flip

      Use a full atomic call instead. intel_crtc_page_flip will still
      have to live until async updates are allowed.

      This doesn't seem to be a regression from the convert to atomic,
      part 3 patch. During GPU reset it fixes the following warning:

      Revert "drm/i915: Read hw state into an atomic state struct, v2."

      This reverts commit 3bae26eb2991c00670df377cf6c3bc2b0577e82a.

      Seems it introduces regressions for 3 different reasons, oh boy..

      In bug #90868 as I can see the atomic state will be restored on
      resume without the planes being set up properly. Because plane
      setup here requires the atomic state, we'll have to settle
      for committing atomic planes first.

      In bug #90861 the failure appears to affect mostly DP devices,
      and happens because reading out the atomic state prevents a modeset
      on boot, which would require better hw state readout.

      In bug #90874 it's shown that cdclk should be part of the atomic
      state, so only performing a single modeset during resume excarbated
      the issue.

      It's better to fix those issues first, and then commit this patch,
      so do that temporarily.

      This reverts commit 490f400db5d886fc28566af69b02f6497f31be4b.

      We're not ready yet to make it atomic, we calculate some state in
      advance, but without atomic plane support atomic the hw readout will
      fail.

      It's required to revert this commit to revert the atomic hw
      state readout patch.

      This is a small behavioral change because it leaves DVO_2X_MODE

      drm/i915: Calculate haswell plane workaround, v5.

      This needs to be done last after all modesets have been calculated.

      A modeset first disables all crtc's, so any crtc that undergoes a
      modeset counts as inactive.

      If no modeset's done, or > 1 crtc's stay w/a doesn't apply.
      Apply workaround on the first crtc if 1 crtc stays active.
      Apply workaround on the second crtc if no crtc was active.

      Changes since v1:
       - Use intel_crtc->atomic as a place to put hsw_workaround_pipe.
       - Make sure quirk only applies to haswell.
       - Use first loop to iterate over newly enabled crtc's only.
         This increases readability.
      Changes since v2:
       - Move hsw_workaround_pipe back to crtc_state.
      Changes since v3:
       - Return errors from haswell_mode_set_planes_workaround.
      Changes since v4:
      - Clean up commit message.

      This change had to be done after converting suspend/resume to
      use atomic_state so the atomic state is preserved, otherwise
      all transitional state is erased.

      Now all callers of .crtc_enable and .crtc_disable go through
      atomic modeset! :-D

      drm/i915: Read hw state into an atomic state struct, v2.

      To make this work we load the new hardware state into the
      atomic_state, then swap it with the sw state.

      This lets us change the force restore path in setup_hw_state()
      to use a single call to intel_mode_set() to restore all the
      previous state.

      As a nice bonus this kills off encoder->new_encoder,
      connector->new_enabled and crtc->new_enabled. They were used only
      to restore the state after a modeset.

      Changes since v1:
      - Make sure all possible planes are added with their crtc set,
        so they will be turned off on first modeset.

      Solve it by using the newly introduced 
drm_atomic_helper_commit_planes_on_crtc.

      The problem here was that the drm_atomic_helper_commit_planes() helper
      we were using was basically designed to do

          begin_crtc_commit(crtc #1)
          begin_crtc_commit(crtc #2)
          ...
          commit all planes
          finish_crtc_commit(crtc #1)
          finish_crtc_commit(crtc #2)

      The problem here is that since our hardware relies on vblank evasion,
      our CRTC 'begin' function waits until we're out of the danger zone in
      which register writes might wind up straddling the vblank, then disables
      interrupts; our 'finish' function re-enables interrupts after the
      registers have been written.  The expectation is that the operations 
between
      'begin' and 'end' must be performed without sleeping (since interrupts
      are disabled) and should happen as quickly as possible.  By clumping all
      of the 'begin' calls together, we introducing a couple problems:
       * Subsequent 'begin' invocations might sleep (which is illegal)
       * The first 'begin' ensured that we were far enough from the vblank that
         we could write our registers safely and ensure they all fell within
         the same frame.  Adding extra delay waiting for subsequent CRTC's
         wasn't accounted for and could put us back into the 'danger zone' for
         CRTC #1.

      This commit solves the problem by using a new helper that allows an
      order of operations like:

         for each crtc {
              begin_crtc_commit(crtc)  // sleep (maybe), then disable interrupts
              commit planes for this specific CRTC
              end_crtc_commit(crtc)    // reenable interrupts
         }

      so that sleeps will only be performed while interrupts are enabled and
      we can be sure that registers for a CRTC will be written immediately
      once we know we're in the safe zone.

      The crtc->config->base.crtc update may seem unrelated, but the helper
      will use it to obtain the crtc for the state. Without the update it
      will dereference NULL and crash.

      drm/i915: Use crtc_state->active instead of crtc_state->enable

      crtc_state->enable means a crtc is configured, but it may be turned
      off for dpms. Until the commit "use intel_crtc_control everywhere"
      crtc_state->active was not updated on crtc off, but now
      crtc_state->active should be used for tracking whether a crtc is
      scanning out or not.

      A few commits from now dpms will be handled by calling
      intel_set_mode with a different value for crtc_state->active,
      which causes a crtc to turn on or off.

      At this point crtc->active should mirror crtc_state->active,
      so some paranoia from the crtc_disable functions can be removed.

      intel_set_mode_setup_plls still checks for ->enable, because all
      resources that are needed have to be calculated, else
      dpms changes may not succeed.

      drm/i915/bxt: fix DDI PHY vswing scale value setting

      According to bspec the DDI PHY vswing scale value is "don't care" in
      case the scale enable bit [27] is clear. But this doesn't seem to be
      correct. The scale value seems to also matter if the scale mode bit
      [26] is set. So both bit 26 and 27 depend on the value. Setting the
      scale value to 0 while either bit is set results in a failed modeset on
      HDMI (sink reports no signal).

      After reset the scale value is 0x98, but according to the spec we have
      to program it to 0x9a. So for consistency program it always to 0x9a
      regardless of the scale enable bit.

      far as I know) where we boot with display not initialized.

      ARM: OMAP3: dpll3-m2: get rid of obsolete clksel access

      Core DVFS support code is currently referencing clksel functionality, 
which
      is wrong. The m2 divisor has been implemented as a divider clock for a 
long
      time already, so replace the validrate check call with proper

      Core DVFS is currently not supported in the kernel so verifying this patch

      drm/i915/skl: Make sure to break when not finding suitable PLL dividers

      Right now, when finishing the cycle with odd dividers without finding a
      suitable candidate, we end up in an infinite loop. Make sure to break in
      that case.

      deb-pkg: Add device tree blobs to the package

      When building a package with make deb-pkg (say, for arm), the dtb files 
are
      not added to the package. Given that things are still evolving on arm, it
      make sense to have them along with the kernel and modules.

      builddeb: fix stripped module signatures if CONFIG_DEBUG_INFO and 
CONFIG_MODULE_SIG_ALL are set

      If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are
      automatically signed in the result package, as it's for rpm-pkg, 
binrpm-pkg,
      tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO
      is NOT set. In that case deb-package contains signed modules.

      But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with
      debug information. To do that, debug information from all modules
      is copied into separate files by objcopy. And loadable kernel modules are
      stripped afterwards. Stripping removes previously (during modules_install)
      added signatures from loadable kernel modules. Therefore final deb-package
      contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL.

      This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set
      to solve this problem.

      create_package() function tries to resolve used architecture
      for everry package. Split the setting the architecture to a

      This allows using debarch from other parts of script as
