    x86: don't change affinity with interrupt unmasked
    With ->startup unmasking the IRQ, setting the affinity afterwards
    without masking the IRQ again is invalid namely for MSI (address and
    data can't be updated atomically and may - at least for MSI-X - be
    cached while unmasked).

    x86_emulate: fix EFLAGS setting of CMPXCHG emulation
    CMPXCHG sets CF, PF, AF, SF, and OF flags according to the results of the
    comparison the rAX with the operand of the instruction.
    rAX must be the first argument of the comparison (a minuend), the operand
    must be the second one (a subtrahend).
    Due to improper order of comparison arguments, CF, PF, AF, SF and OF flags 
    set incorrectly in the case of inequality. Need to swap them.

    x86/hvm: implicitly disable an ioreq server when it is destroyed
    Currently, unless a (non-default) ioreq server is explicitly disabled before
    being destroyed, its gmfns will not be placed back into the p2m but still
    released back into the ioreq_gmfn mask. This is somewhat counter-intuitive
    and easily remedied by this small patch.

    x86/efi: reserve SMBIOS table region when EFI booting
    Some EFI firmware implementations may place the SMBIOS table in RAM
    marked as BootServicesData, which Xen does not consider as reserved.
    When dom0 tries to access the SMBIOS, the region is not contained in the
    initial P2M and it crashes with a page fault. To fix this, reserve the
    SMBIOS region.
    Also, fix the memcmp checks for existence of the SMBIOS.
