[Benjamin Herrenschmidt]

Hi Linus !

Here are a few powerpc fixes, all aimed at -stable, found in part thanks
to the ramping up of a major distro testing and in part thanks to the LE
guys hitting all sort interesting corner cases.

The most scary are probably the register clobber issues in
csum_partial_copy_generic(), especially since Anton even had a test case
for that thing, which didn't manage to hit the bugs :-)

Another highlight is that memory hotplug should work again with these
fixes.

Oh and the vio modalias one is worse than the cset implies as it upsets
distro installers, so I've been told at least, which is why I'm shooting
it to stable.

Cheers,
Ben.
