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 more fixes for powerpc 3.10.  It's a bit more than I
  would have liked this late in the game but I suppose that's what
  happens with a brand new chip generation coming out.

  A few regression fixes, some last minute fixes for new P8 features
  such as transactional memory,...

  There's also one powerpc KVM patch that I requested that adds two
  missing functions to our in-kernel interrupt controller support which
  is itself a new 3.10 feature.  These are defined by the base
  hypervisor specification.  We didn't implement them originally because
  Linux doesn't use them but they are simple and I'm not comfortable
  having a half-implemented interface in 3.10 and having to deal with
  versionning etc...  later when something starts needing those calls.
  They cannot be emulated in qemu when using in-kernel interrupt
  controller (not enough shared state).

  Just added a last minute patch to fix a typo introducing a breakage in
  our cputable for Power7+ processors, sorry about that, but the
  regression it fixes just hurt me :-)"
