[git pull] Please pull powerpc.git merge branch

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

Hi Linus !

I lied :-) There is a couple more features coming in. Mostly Roland
tracehook stuff which came in a bit late but since the generic bits
are in and he had some powerpc support ready, we felt like it was
something worth having. There's also some SPI bits from Grant who
were around but took some time to be fully acked and some stuff to
expose our cache topology through sysfs that we wanted but took a
bit longer to finish than expected.

The rest is mostly fixes.

It's all in:

git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git merge

(Hopefully no silly non-printable character this time, at least
nothing I manage to spot with evo but who knows...)

Cheers,
Ben.
