  powerpc/mm: Ensure cpumask update is ordered (2017-08-18 13:07:16 +1000)

----------------------------------------------------------------
powerpc fixes for 4.13 #8

Just one fix, to add a barrier in the switch_mm() code to make sure the mm
cpumask update is ordered vs the MMU starting to load translations. As far as we
know no one's actually hit the bug, but that's just luck.

Thanks to:
  Benjamin Herrenschmidt, Nicholas Piggin.
