Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Pull powerpc fixes from Ben Herrenschmidt:
 "Here are a few powerpc fixes, all aimed at -stable, found in part
  thanks to the ramping up of a major distro testing and in part thanks
  to the LE guys hitting all sort interesting corner cases.

  The most scary are probably the register clobber issues in
  csum_partial_copy_generic(), especially since Anton even had a test
  case for that thing, which didn't manage to hit the bugs :-)

  Another highlight is that memory hotplug should work again with these
  fixes.

  Oh and the vio modalias one is worse than the cset implies as it
  upsets distro installers, so I've been told at least, which is why I'm
  shooting it to stable"
