commit fe0d67576e335c02becf1cea8e67005509fa90b6

    x86/xstate: Fix array overrun on hardware with LWP
    
    c/s da62246e4c "x86/xsaves: enable xsaves/xrstors/xsavec in xen" introduced
    setup_xstate_features() to allocate and fill xstate_offsets[] and
    xstate_sizes[].
    
    However, fls() casts xfeature_mask to 32bits which truncates LWP out of the
    calculation.  As a result, the arrays are allocated too short, and the cpuid
    infrastructure reads off the end of them when calculating xstate_size for 
the
    guest.
    
    On one test system, this results in 0x3fec83c0 being returned as the maximum
    size of an xsave area, which surprisingly appears not to bother Windows or
    Linux too much.  I suspect they both use current size based on xcr0, which 
Xen
    forwards from real hardware.

    x86/pv: Check that emulate_privileged_op() don't change any unexpected flags
    
    No bits, other than arithmetic ones and the resume flag (which will most
    likely change from 1 to 0), can be changed by the instructions we permit.
    Extend the check to cover other flags.

    x86/emul: Calculate not_64bit during instruction decode
    
    ... rather than repeating "generate_exception_if(mode_64bit(), EXC_UD);" in
    the emulation switch statement.
    
    Bloat-o-meter shows:
    
      add/remove: 0/0 grow/shrink: 1/2 up/down: 8/-495 (-487)
      function                                     old     new   delta

      x86_decode                                  6782    6726     -56
      x86_emulate                                57160   56721    -439
    
    The reason for x86_decode() getting smaller is that this change alters the
    x86_decode_onebyte() switch statement from a chain of if()/else's to a jump
    table.  The jump table adds 250 bytes of data which bloat-o-meter clearly
    can't see.
