Linux 3.18 rc3

Another week, another rc, and things aren't really shrinking the way I
would hope for...

While the patch itself is much smaller than rc2 was (no new filesystem
this rc!), there are actually more commits and more files affected.
It's all over, too.

That said, I don't think there is anything particularly horrible in
here. Lots and lots of small stuff, with drivers accounting for the
bulk of it (both in commits and in lines), but networking and core
kernel showing up too. Nothing particularly stands out.

Shortlog appended for details, please go forth and test.
