    Revert "x86/paging: make log-dirty operations preemptible"
    
    This reverts commit 6fbd99d7cc46a91566839e85bffb9bff406adbae.
    
    This fix has been discovered to cause regressions.  Investigations are
    ongoing.

commit 35e7ae5f66f34bd93dff089587da3b3665622eff
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
Date:   Tue Aug 12 16:10:01 2014 +0200

    x86/cpu: undo BIOS CPUID max_leaf limit before querying for features
    
    If IA32_MISC_ENABLE[22] is set by the BIOS, CPUID.0.EAX will be limited to 
3.
    Lift this limit before considering whether to query CPUID.7[ECX=0].EBX for
    features.
    
    Without this change, dom0 is able to see this feature leaf (as the limit was
    subsequently lifted), and will set features appropriately in HVM domain 
cpuid
    policies.
    
    The specific bug XenServer observed was the advertisement of the FSGSBASE
    feature, but an inability to set CR4.FSGSBASE as Xen considered the bit to 
be
    reserved as cpu_has_fsgsbase incorrectly evaluated as false.
    
    This is a regression introduced by c/s 44e24f8567 "x86: don't call
    generic_identify() redundantly" where the redundant call actually resampled
    CPUID.7[ECX=0] properly to obtain the feature flags.

    x86/paging: make log-dirty operations preemptible
    
    Both the freeing and the inspection of the bitmap get done in (nested)
    loops which - besides having a rather high iteration count in general,
    albeit that would be covered by XSA-77 - have the number of non-trivial
    iterations they need to perform (indirectly) controllable by both the
    guest they are for and any domain controlling the guest (including the
    one running qemu for it).
    
    This is CVE-2014-5146 / XSA-97.

commit bba8f285cf5f4248c9057e69aaafee2ec4dd5392
Author: Robert Phillips <robert.phillips@xxxxxxxxxx>
Date:   Tue Aug 12 16:08:10 2014 +0200

    x86/mm/hap: Adjust vram tracking to play nicely with log-dirty.
    
    The previous code assumed the guest would be in one of three mutually 
exclusive
    modes for bookkeeping dirty pages: (1) shadow, (2) hap utilizing the log 
dirty
    bitmap to support functionality such as live migrate, (3) hap utilizing the
    log dirty bitmap to track dirty vram pages.
    Races arose when a guest attempted to track dirty vram while performing live
    migrate.  (The dispatch table managed by paging_log_dirty_init() might 
change
    in the middle of a log dirty or a vram tracking function.)
    
    This change allows hap log dirty and hap vram tracking to be concurrent.
    Vram tracking no longer uses the log dirty bitmap.  Instead it detects
    dirty vram pages by examining their p2m type.  The log dirty bitmap is only
    used by the log dirty code.  Because the two operations use different
    mechanisms, they are no longer mutually exclusive.
