This series looks good to me. While you'd better talk to fuqiang to ask
if he wants to post these or wants to give up. He posted patch to raise
the potention issue and I suggested him to do these during the
discussion. Without consulting him for opinion to take over a discussing
work, it's not suggested, I would say.
