I wouldnt've done even that but only the x86 asm version of
protected_guest.h and left it to other arches to extend it. I don't
like "preempting" use of functionality by other arches and would
leave them to extend stuff themselves, as they see fit, but ok,
ARCH_HAS_PROTECTED_GUEST sounds clean enough to me too, so sure, that's
fine too.
