This is based on the "next" branch of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git I am not doing changelog here as it is 4 months since last respin and I am sure everybody lost the context anyway, I tried to be as detailed as I could in the very last patch, others are pretty trivial anyway. Please comment. Thanks.
