Linux 3.9 rc8

Yes, I was really hoping (and originally planning) to release 3.9final this weekend, but we had enough issues that I just didn't feelcomfy about it. It was borderline, and none of the issues were huge,and maybe I could have called this just 3.9 and opened the mergewindow, but hey, another week won't hurt.The bulk of the changes here are networking (both core and drivers),but there's arch fixes (sparc, x86, arm, powepc) and random otherstuff. A couple of reverts and some cleanups. The shortlog gives someflavor of the details. Nothing here on its own would have delayed 3.9for me, but I was hoping for a calmer week.Please don't send me pull requests unless it's something reallycritical, and let's aim for a nice calm 3.9 release next weekend, ok?
