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

Pull powerpc fixes from Ben Herrenschmidt:
 "Here's a few powerpc fixes for 3.9, mostly regressions (though not all
  from 3.9 merge window) that we've been hammering into shape over the
  last couple of weeks.  They fix booting on Cell and G5 among other
  things (yes, we've been a bit sloppy with older machines this time
  around)."
