True, but I left that as a future optimization for now, given the size
the patch-set already has. The idea is to add an abstraction around
VMMCALL for the support code of the various hypervisors and just do a
VMGEXIT in that wrapper when in an SEV-ES guest. But again, that is a
separate patch-set.

Regards,

Joerg
