Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull more powerpc updates from Ben Herrenschmidt:
"Here are the remaining bits I was mentioning earlier. Mostly bug
fixes and new selftests from Michael (yay !). He also removed the WSP
platform and A2 core support which were dead before release, so less
clutter.
One little "feature" I snuck in is the doorbell IPI support for
non-virtualized P8 which speeds up IPIs significantly between threads
of a core"
