    x86: fix information leak on AMD CPUs
    
    The fix for XSA-52 was wrong, and so was the change synchronizing that
    new behavior to the FXRSTOR logic: AMD's manuals explictly state that
    writes to the ES bit are ignored, and it instead gets calculated from
    the exception and mask bits (it gets set whenever there is an unmasked
    exception, and cleared otherwise). Hence we need to follow that model
    in our workaround.
    
    This is CVE-2016-3158 / CVE-2016-3159 / XSA-172.

commit 16ca37fadf4fe13a3987dfec247083bde44a8444
Author: David Vrabel <david.vrabel@xxxxxxxxxx>

    x86/fpu: improve check for XSAVE* not writing FIP/FDP fields
    
    The hardware may not write the FIP/FDP fields with a XSAVE*
    instruction.  e.g., with XSAVEOPT/XSAVES if the state hasn't changed
    or on AMD CPUs when a floating point exception is not pending.  We
    need to identify this case so we can correctly apply the check for
    whether to save/restore FCS/FDS.
    
    By poisoning FIP in the saved state we can check if the hardware
    writes to this field.  The poison value is both: a) non-canonical; and
    b) random with a vanishingly small probability of matching a value
    written by the hardware (1 / (2^63) = 10^-19).
    
    The poison value is fixed and thus knowable by a guest (or guest
    userspace).  This could allow the guest to cause Xen to incorrectly
    detect that the field has not been written.  But: a) this requires the
    FIP register to be a full 64 bits internally which is not the case for
    all current AMD and Intel CPUs; and b) this only allows the guest (or
    a guest userspace process) to corrupt its own state (i.e., it cannot
    affect the state of another guest or another user space process).
    
    This results in smaller code with fewer branches and is more
    understandable.

    Intel confirmed that 64-bit {F,}XRSTOR sign-extend FIP from bit 47.
    While leaving the description above intact, modify the code comment
    accordingly.

    restore p2m_access_t enum order to allow bitmask semantics
    
    Nested hap code assumed implict bitmask semantics of the p2m_access_t
    enum prior to C/S 4c63692d7c38c5ac414fe97f8ef37b66e05abe5c
    
    The change to the enum ordering broke this assumption and caused functional
    problems for the nested hap code. As it may be error prone to audit and find
    all other p2m_access users assuming bitmask semantics, instead restore the
    previous enum order and make it explict that bitmask semantics are to be
    preserved for the read, write and execute access types.

    x86/hvm: add HVM_PARAM_X87_FIP_WIDTH
    
    The HVM parameter HVM_PARAM_X87_FIP_WIDTH to allow tools and the guest
    to adjust the width of the FIP/FDP registers to be saved/restored by
    the hypervisor.  This is in case the hypervisor hueristics do not do
    the right thing.
    
    Add this parameter to the set saved during domain save/migrate.

    x86/fpu: add a per-domain field to set the width of FIP/FDP
    
    The x86 architecture allows either: a) the 64-bit FIP/FDP registers to
    be restored (clearing FCS and FDS); or b) the 32-bit FIP/FDP and
    FCS/FDS registers to be restored (clearing the upper 32-bits).
    
    Add a per-domain field to indicate which of these options a guest
    needs.  The options are: 8, 4 or 0.  Where 0 indicates that the
    hypervisor should automatically guess the FIP width by checking the
    value of FIP/FDP when saving the state (this is the existing
    behaviour).
    
    The FIP width is initially automatic but is set explicitly in the
    following cases:
    
    - 32-bit PV guest: 4
    - Newer CPUs that do not save FCS/FDS: 8
    
    The x87_fip_width field is placed into an existing 1 byte hole in
    struct arch_domain.
