Merge tag 'powerpc-4.12-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
"Mostly fairly minor, of note are:
- Fix percpu allocations to be NUMA aware
- Limit 4k page size config to 64TB virtual address space
- Avoid needlessly restoring FP and vector registers
Thanks to Aneesh Kumar K.V, Breno Leitao, Christophe Leroy, Frederic
Barrat, Madhavan Srinivasan, Michael Bringmann, Nicholas Piggin,
