    libxl: adjust PoD target by memory fudge, too

    PoD guests need to balloon at least as far as required by PoD, or risk
    crashing.  Currently they don't necessarily know what the right value
    is, because our memory accounting is (at the very least) confusing.

    Apply the memory limit fudge factor to the in-hypervisor PoD memory
    target, too.  This will increase the size of the guest's PoD cache by
    the fudge factor LIBXL_MAXMEM_CONSTANT (currently 1Mby).  This ensures
    that even with a slightly-off balloon driver, the guest will be
    stable even under memory pressure.

    There are two call sites of xc_domain_set_pod_target that need fixing:

    The one in libxl_set_memory_target is straightforward.

    The one in xc_hvm_build_x86.c:setup_guest is more awkward.  Simply
    setting the PoD target differently does not work because the various
    amounts of memory during domain construction no longer match up.
    Instead, we adjust the guest memory target in xenstore (but only for
    PoD guests).

    This introduces a 1Mby discrepancy between the balloon target of a PoD
    guest at boot, and the target set by an apparently-equivalent `xl
    mem-set' (or similar) later.  This approach is low-risk for a security
    fix but we need to fix this up properly in xen.git#staging and
    probably also in stable trees.

    This is XSA-153.

    x86: rate-limit logging in do_xen{oprof,pmu}_op()

    Some of the sub-ops are acessible to all guests, and hence should be
    rate-limited. In the xenoprof case, just like for XSA-146, include them
    only in debug builds. Since the vPMU code is rather new, allow them to
    be always present, but downgrade them to (rate limited) guest messages.

    This is CVE-2015-7971 / XSA-152.

    x86/PoD: Eager sweep for zeroed pages

    Based on the contents of a guests physical address space,
    p2m_pod_emergency_sweep() could degrade into a linear memcmp() from 0 to
    max_gfn, which runs non-preemptibly.

    As p2m_pod_emergency_sweep() runs behind the scenes in a number of contexts,
    making it preemptible is not feasible.

    Instead, a different approach is taken.  Recently-populated pages are 
eagerly
    checked for reclaimation, which amortises the p2m_pod_emergency_sweep()
    operation across each p2m_pod_demand_populate() operation.

    Note that in the case that a 2M superpage can't be reclaimed as a superpage,
    it is shattered if 4K pages of zeros can be reclaimed.  This is unfortunate
    but matches the previous behaviour, and is required to avoid regressions
    (domain crash from PoD exhaustion) with VMs configured close to the limit.

    This is CVE-2015-7970 / XSA-150.

    x86: guard against undue super page PTE creation

    When optional super page support got added (commit bd1cd81d64 "x86: PV
    support for hugepages"), two adjustments were missed: mod_l2_entry()
    needs to consider the PSE and RW bits when deciding whether to use the
    fast path, and the PSE bit must not be removed from L2_DISALLOW_MASK
    unconditionally.

    This is CVE-2015-7835 / XSA-148.

    arm: handle races between relinquish_memory and free_domheap_pages

    Primarily this means XENMEM_decrease_reservation from a toolstack
    domain.

    Unlike x86 we have no requirement right now to queue such pages onto
    a separate list, if we hit this race then the other code has already
    fully accepted responsibility for freeing this page and therefore
    there is no more for relinquish_memory to do.

    This is CVE-2015-7814 / XSA-147.

    arm: Support hypercall_create_continuation for multicall

    Multicall for ARM has been supported since commit f0dbdc6 "xen: arm: fully
    implement multicall interface.". Although, if an hypercall in multicall
    requires preemption, it will crash the host:

    Looking to the code, the support of multicall looks valid to me, as we only
