commit 8867a48e058ab04bd269cab12ef4de5ee8ad5b7b
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
Date:   Mon Dec 19 12:05:20 2016 +0000

    x86/hvm: Don't emulate all instructions hitting the #UD intercept
    
    Having the instruction emulator fill in all #UDs when using FEP is unhelpful
    when trying to test emulation behaviour against hardware.
    
    Restrict emulation from the #UD intercept to the cross-vendor case, and 
when a
    postive Forced Emulation Prefix has been identified.
