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

Pull powerpc fixes from Ben Herrenschmidt:
 "Here are 3 bug fixes that should probably go into 3.11 since I'm also
  tagging them for stable.

  Once fixes our old /proc/powerpc/lparcfg file which provides partition
  informations when running under our hypervisor and also acts as a
  user-triggerable Oops when hot :-(

  The other two respectively are a one liner to fix a HVSI protocol
  handshake problem causing the console to fail to show up on a bunch of
  machines until we reach userspace, which I deem annoying enough to
  warrant going to stable, and a nasty gcc miscompile causing us to pass
  virtual instead of physical addresses to the firmware under some
  circumstances"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/hvsi: Increase handshake timeout from 200ms to 400ms.
  powerpc: Work around gcc miscompilation of __pa() on 64-bit
  powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisor
