I see them as bits of code that are being moved from KVM to the kernel
core. I think moving those bits outside arch/x86/kvm/ makes this more
clear: people can expect that code living in arch/x86/kvm/ is never
used if CONFIG_KVM was not set.

Because of their location, I thought svm.h and vmx.h had KVM-specific
code. Now I've noticed they are independent from KVM. May I move svm.h
and vmx.h to arch/x86/include/asm, then?
