Hi Alexander,
Today's linux-next merge of the kvm-ppc tree got a conflict in
arch/powerpc/kvm/44x_emulate.c between commits from the kvm tree and
the same patches plus another commit from the kvm-ppc tree.
I just used the kvm-ppc tree version.
This happened because

Well, IMHO, guest API != user-space. Maybe we should have a parallel
mechanism to uapi to make the kvm guest header files available.
