commit 972523bcefe215b46ffd74fa08b8199cec2fde05
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
Date:   Mon Apr 11 10:03:55 2016 +0100

    x86/pv: Correctly fold vIOPL back into vcpu_guest_context
    
    c/s f71ecb6 "x86: introduce a new VMASSIST for architectural behaviour of
    iopl" shifted the vcpu iopl field by 12, but didn't update the logic which
    reconstructs the guests eflags for migration.
    
    Existing guest kernels set a vIOPL of 1, to prevent them from faulting when
    accessing IO ports.  This bug manifests as a crash after migrate, as the 
vIOPL
    reverts back to the default of 0, and the guest suffers an unexpected #GP
    fault.
