Merge tag 'powerpc-4.8-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Ben Herrenschmidt:
"This was meant to be sent early last week, but I has a change pending
on one of the fixes and other things made me forget all about. Ugh.
We have some misc fixes for powerpc 4.8. Some trivial bits and some
regressions, and a trivial cleanup or two that I saw no point in
letting rot in patchwork"
