Kernel prepatch 3.7-rc5

The 3.7 cycle continues with the 3.7-rc5
release. "This is quite a small -rc, I'm happy to say. -rc4 was
already fairly calm, and -rc5 has fewer commits still. And more
importantly, apart from one revert, and a pinctl driver update, it's not
just a fairly small number of commits, they really are mostly
one-liners."
