MAINTAINERS updates in stable trees

I just saw an update to the MAINTAINERS file fly by on stable@ and figured we might want to be grabbing all of those into our stable trees?

Unlike documentation, it's not something the case that it can diverge from the code, and it's also very unlikely that someone wants to keep recieving mails as a result of someone who runs get_maintainers.pl on older kernels after he has removed his name upstream.

Any objections to taking these updates? It'll grow our patch count, but that's one of the rare cases where I don't see a way for it to cause regressions...
