You can add my Acked-by: Grant Likely <grant.likely at linaro.org> to the
first patch. I've not reviewed out the second or third patches yet.

None of this appears to be in linux-next yet. I've boot tested on
PowerPC, but that isn't the same as an ack by the PowerPC maintainers.
It is probably too late for the whole now since we're after -rc7.
However, if you ask me to, I have absolutely no problem putting the
first patch into my tree for v3.10 merging. I went over the patch
line-by-line and am convinced that it is functionally identical.

Let me know if you need me to do this.
