Comment 4 for bug 1439562

Jeremy - I've just had a look at the patches you are proposing. Even though this set only affects powernv, I would really prefer to cherry-pick them from Linus' repo, or at least linux-next. Getting them after they have gone through a thorough review cycle helps prevent conflict carnage in this and later kernels. I'd be willing to add these as an SRU after they have been merged upstream.
