Merge branch 'kvm-ppc-cap-210' into kvm-master
By request of Nick Piggin:
> Patch 3 requires a KVM_CAP_PPC number allocated. QEMU maintainers are
> happy with it (link in changelog) just waiting on KVM upstreaming. Do
> you have objections to the series going to ppc/kvm tree first, or
> another option is you could take patch 3 alone first (it's relatively
> independent of the other 2) and ppc/kvm gets it from you?
