You know, currently make sync would sync header files to userspace from
include/asm-x86/, so kvm.h and kvm_host.h are always synced from there
for any archs. Since some arch-specific stuff for save/restore should be
defined in include/asm-$arch/(kvm.h; kvm_host.h), so ia64 or other archs
should need it when they implement save/restore.
