The VMMCALL instruction doesn't get recognised and isn't processed
by the emulator.
This is seen on an Intel host that tries to execute the VMMCALL
instruction after a guest live migrates from an AMD host.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
