Looks good to me except one thing. I don't see how you are addressing
the problem fixed by commit b8a7857071b477b28d3055e33ff0298fc91f329a
in qemu-kvm. The problem is that mp_state can change in kernel between
call to kvm_cpu_synchronize_state() and vcpu re-entry. In this case old
mp_state will overwrite new one.
