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

Pull more powerpc updates from Ben Herrenschmidt:
 "Here are the remaining bits I was mentioning earlier.  Mostly bug
  fixes and new selftests from Michael (yay !).  He also removed the WSP
  platform and A2 core support which were dead before release, so less
  clutter.

  One little "feature" I snuck in is the doorbell IPI support for
  non-virtualized P8 which speeds up IPIs significantly between threads
  of a core"
