This of course touches two maintainers' areas.  Michael and Paolo, how
do you want to proceed here?  Can this just go through Michael's tree?
Or should I make a topic branch off Linus' tree that you can both
pull, or should I split the patch into two (i.e. everything except the
kvm_book3s_64.h change in the first patch, and the kvm_book3s_64.h
change in the second) and get Michael to put the first one in a topic
branch that I can then pull and apply the second patch onto?

This patch seems separate from the other two (I can't really tell since
there wasn't a cover letter on linuxppc-dev).  Can you place it in a
pull request for both Michael and myself?

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.
