Merge branch 'for-linus' of git://

Pull powerpc fixes from Michael Ellerman:

  There's nothing too exciting.  The CONFIG_FHANDLE one is annoying, I
  know you love defconfig changes.  But we've had a couple of developers
  waste time debugging boxes that wouldn't boot, only to realise it's
  just that systemd needs CONFIG_FHANDLE and our defconfigs don't have

  The new syscalls seem to be working, I've run the selftests that
  exist, and also let trinity bash on them for a while"
