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

Pull more powerpc updates from Ben Herrenschmidt:
 "Here are some more powerpc bits for 3.17, essentially fixes.

  The biggest series, also aimed at -stable, is from Aneesh and is the
  result of weeks and weeks of debugging to find out why the heck or THP
  implementation was occasionally triggering multi-hit errors in our
  level 1 TLB.  It ended up being a combination of issues including
  subtleties as to how we should invalidate those special 'MPSS' pages
  we use to allow the use of 16M pages inside 4K/64K "base page size"
  segments (you really have to love our MMU !)

  Another interesting one in the "OMG" category is the series from
  Michael adding memory barriers to spin_is_locked().  That's also the
  result of many days of debugging to figure out why the semaphore code
  would occasionally crash in ways that made no sense.  It ended up
  being some creative lock stacking that was defeated by the fact that
  our locks allow a load inside the locked section to be re-ordered with
  the load of the lock value itself (I'm still of two mind about whether
  to kill that once and for all by putting a heavier barrier back into
  our lock implementation...).  The fixes come with a long explanation
  in the cset comments, feel free to read it if you feel like having a
  headache today"
