Thanks, Chuck!

I just noticed I made a separate mistake this time around.  For some
reason my pull request only included about the first half of the commits
I had queued up in linux-next.

I have some lame excuse having to do with holiday travel.

Anyway the remainder was just another 20-some bug fixes of various
levels of importance, so I think I'll just send another request for -rc2
tomorrow....
