    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 
    Lift this limit before considering whether to query CPUID.7[ECX=0].EBX for
    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 
    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 
    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.

    xen: arm: Correctly handle exception injection from userspace on 64-bit.
    Firstly we must be prepared to propagate traps from 32-bit userspace even 
    64-bit guests, so wrap the existing inject_undef??_exception into
    inject_undef_exception and use that when injecting an undef exception. The
    various other exception cases (aborts etc) already do this.
    Secondly when injecting the trap we must pick the correct exception vector
    depending on whether the source of the trap was 32-bit EL0, 64-bit EL0 or

    xen: arm: handle AArch32 userspace when dumping 64-bit guest state.
    A 64-bit guest can still be in 32-bit mode when running userspace,
    handle this case by dumping the correct 32-bit state.
    Note that on ARM it is not possible to change mode without the help
    of the next exception level, hence there is no way a 64-bit guest can
    be running in 32-bit kernel modes.

    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.
