Merge tag 'powerpc-4.13-8' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fix from Michael Ellerman:
"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"
