Linux 3.6 rc6

Ok, another week, another -rc.

And as I suspected, the reason -rc5 was so small was that a lot of
people were still getting ready after the Kernel Summit. So -rc6 is a
bit larger, since people were playing catch-up. That said, it's not
*huge* either, and it's not like it looks scary, but it's definitely
not tiny.

Fairly normal statistics: two thirds drivers, with the remaining third
being a mix of architecture updates, filesystems (gfs2 and nfs) and
random core stuff (scheduler, workqueue, stuff like that).

Please do test things out, I'd really like to be able to do the final
3.6 soonish..
