Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.5-20151130' into staging

ppc patch queue for qemu-2.5 20151130

target-ppc and related bugfix patches for qemu-2.5

I don't have the facilities to test the Macintosh and BookE related
patches.  I've sanity checked them (inspection + make check), but I'm
otherwise relying on the submitters.
