* Fix a KVM SMP guest hang. This is not completely trivial, but just
  small enough to merge it. If this causes any more problems, we can
  revert it and the timebase patch which exposed the underlying issue
  for release.
* Fix a bunch of Coverity issues reported introduced in ppc, mostly in
  powernv code.
* Fix a NetBSD boot bug on mac99 caused by VSX/VMX decodetree rewrite.
* Fix the default CPU selection for older spapr machines.
