eh, not crazy about the idea. x86 has
arch/x86/include/asm/kvm_guest.h, which may be the most appropriate,
or this could be generalized to other architectures as well and
included in include/linux/kvm_host.h.

we can just stick it in arch/arm/kvm/arm.c for now and move later if
need be, no need to create a fuzz.
