Linux 3.7 rc8

I really didn't want it to come to this, but I was uncomfortable doing
the 3.7 release yesterday due to last-minute issues, and decided to
sleep on it.

And today, I ended up even *less* comfortable about it due to the
resurrection of a kswapd issue, so I decided that I'm going to do
another -rc after all.

Which is not very nice timing-wise, since that means that the next
merge window will run up very close to christmas, but hey, maybe that
will at least convince people to not leave things to the final days of
the merge window, and send me pull requests *early*. That would be
nice.

And because I'm dragging it out for another week, I'm going to be
*very* bitter if anybody sends me pull requests this late in the game
that aren't for major issues. If you send me small irrelevant stuff
that doesn't fix major issues (oopses, security, things like that),
I'm going to curse at you and ignore your pull request. So don't do
it.

The only things I want to see are fixes that people care deeply about.
If it's not critical, or you don't have an actual problem report from
an actual user, just put it in the queue under the christmas tree, and
let it got for 3.8.

(Ok, while writing this I got another pull request that made me go "We
don't really need this". I'll pull that, because technically it came
in before I'd given people this warning, but ...)
