So I would hold off this for now. OTOH, it is a good idea to use the same idiom to access ../../../virt/kvm from the arch directories. Can you change x86/PPC/s390/ia64 as well to use $(KVM) instead of $(addprefix)?

On the road to turn KVM/arm64 into something more sensible, change the way we compile the VGIC and arch_timer code by using local Makefiles instead of the very backward method we used before.
