Yes, it is separate.  I have put it in a new kvm-ppc-infrastructure
branch, which I have merged into my kvm-ppc-next branch (since there
are some other patches on that branch which are prerequisites for some
patches in kvm-ppc-next).  Michael can pull kvm-ppc-infrastructure
when he wants to.  I'll send a pull request for kvm-ppc-next tomorrow
assuming today's linux-next merge doesn't cause any problems.

Paul.
