this is an improved version of the patch I sent several weeks ago to

patches it to work on Intel CPUs on the fly. The big difference is that
this version is cleaned up and should work with every future CPU available.

Avi, I prefer not to fold mpstate into kvm_save_registers() as a hidden

save_registers() is not (seems safer).
