    x86: fix slow int80 path after XPTI additions
    For the int80 slow path to jump to handle_exception_saved, %r14 needs to
    be set up suitably for XPTI purposes. This is because of the difference
    in nature between the int80 path (which is synchronous WRT guest
    actions) and the exception path which is potentially asynchronous.
    This is XSA-259.

    x86/msr: Correct the emulation behaviour of MSR_PRED_CMD
    Experimentally, the behaviour of reserved bits in MSR_PRED_CMD changed 
    beta and production microcode, and now raises a #GP fault for set reserved
    bits.  The AMD spec for future hardware also specifies this behaviour, and 
    is the more sensible behaviour to implement.

    x86/msr: further correct the emulation behaviour of MSR_PRED_CMD
    Following commit a6aa678fa3 ("x86/msr: Correct the emulation behaviour
    of MSR_PRED_CMD") we may end up writing the low bit with the wrong
    value. While it's unlikely for a guest to want to write zero there, we
    should still permit (this without incurring the overhead of an actual
    barrier). Correcting this right away will also help whenever further
    bits in the MSR might become defined.

    x86/HVM: suppress I/O completion for port output
    We don't break up port requests in case they cross emulation entity
    boundaries, and a write to an I/O port is necessarily the last
    operation of an instruction instance, so there's no need to re-invoke
    the full emulation path upon receiving the result from an external
    In case we want to properly split port accesses in the future, this
    change will need to be reverted, as it would prevent things working
    correctly when e.g. the first part needs to go to an external emulator,
    while the second part is to be handled internally.
    While this addresses the reported problem of Windows paging out the
    buffer underneath an in-process REP OUTS, it does not address the wider
    problem of the re-issued insn (to the insn emulator) being prone to
    raise an exception (#PF) during a replayed, previously successful memory
    access (we only record prior MMIO accesses).
    Leaving aside the problem tried to be worked around here, I think the
    performance aspect alone is a good reason to change the behavior.
    Also take the opportunity and change bool_t -> bool as
    hvm_vcpu_io_need_completion()'s return type.

    x86/pv: Fix up erroneous segments for 32bit syscall entry
    The existing FLAT_KERNEL_SS expands to the correct value, 0xe02b, but is the
    wrong constant to use.  Switch to FLAT_USER_SS32.
    For compat domains however, the reported values are entirely bogus.
    FLAT_USER_SS32 (value 0xe02b) is FLAT_RING3_CS in the 32bit ABI, while
    FLAT_USER_CS32 (value 0xe023) is FLAT_RING1_DS with an RPL of 3.
    The guests SYSCALL callback is invoked with a broken iret frame, and if left
    unmodified by the guest, will fail on the way back out when Xen's iret tries
    to load a code segment into %ss.
    In practice, this is only a problem for 32bit PV guests on AMD hardware, as
    Intel hardware doesn't permit the SYSCALL instruction outside of 64bit mode.
    This appears to have been broken ever since 64bit support was added to Xen,
    and has gone unnoticed because Linux doesn't use SYSCALL in 32bit builds.

    x86/XPTI: reduce .text.entry
    This exposes less code pieces and at the same time reduces the range
    covered from slightly above 3 pages to a little below 2 of them.
    The code being moved is unchanged, except for the removal of trailing
    blanks, insertion of blanks between operands, and a pointless q suffix
    from "retq".
    A few more small pieces could be moved, but it seems better to me to
    leave them where they are to not make it overly hard to follow code

    x86/spec_ctrl: Fix several bugs in SPEC_CTRL_ENTRY_FROM_INTR_IST
    DO_OVERWRITE_RSB clobbers %rax, meaning in practice that the bti_ist_info
    field gets zeroed.  Older versions of this code had the DO_OVERWRITE_RSB
    register selectable, so reintroduce this ability and use it to cause the
    INTR_IST path to use %rdx instead.
    The use of %dl for the %cs.rpl check means that when an IST interrupt hits
    Xen, we try to load 1 into the high 32 bits of MSR_SPEC_CTRL, suffering a 
    fault instead.
    Also, drop an unused label which was a copy/paste mistake.
