Merge branch 'kvm-ppc-next' of git://git./linux/kernel/git/paulus/powerpc

KVM/PPC update for 4.14

There are various minor fixes and cleanups.  The only new feature is
that we now export information about storage key support to userspace,
so it can advertise it to the guest.

I have pulled in Michael Ellerman's topic/ppc-kvm branch from the
powerpc tree to get a couple of fixes that touch both KVM PPC code and
other PPC code.  That's why there is some arch/powerpc stuff in the
diffstat that isn't arch/powerpc/kvm.
