test branch update

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

I've pushed a few more things to my -test branch (in addition to some
-next updates that I may have forgotten to mention yesterday).

So here's the whole lot of stuff that's in there today vs. upstream.

Please give it a spin, it's really only compile tested here (and I
haven't scrubbed the warnings yet in case they show something bad), so
things will simmer there for a couple of days I think before I'm
confident enough to put them into -next.
