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

Pull more powerpc bits from Ben Herrenschmidt:
 "Here are a few more powerpc bits for this merge window.  The bulk is
  made of two pull requests from Scott and Anatolij that I had missed
  previously (they arrived while I was away).  Since both their branches
  are in -next independently, and the content has been around for a
  little while, they can still go in.

  The rest is mostly bug and regression fixes, a small series of
  cleanups to our pseries cpuidle code (including moving it to the right
  place), and one new cpuidle bakend for the powernv platform.  I also
  wired up the new sched_attr syscalls"
