To anyone who follows the kvm-ppc-next branch in my powerpc repository at git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git, I have had to rebase the branch to avoid bisection breakage, so you will need to do git pull -f or the equivalent to throw away the old commits. The new head of the kvm-ppc-next branch is feafd13c96d6. Paul.
