Arguably the kvm and non-kvm implementations will now come from
different commits in git blame. I personally favor keeping the
git blame consistency over bare code movement that doesn't fix
any actual bug.

Also this patch doesn't seem to be strictly needed to reach the
goal of kicking "kvm_ppc.h" out of user emulation.
