Ok, all applied ontop of 4.5-rc1.

You could take a look if everything's still fine and I haven't botched
anything:

http://git.kernel.org/cgit/linux/kernel/git/bp/bp.git/log/?h=tip-mm

I'll let the build bot chew on it and then test it here and send it out
again to everyone on CC so that people don't act surprised.

Thanks for this cleanup, code looks much better now!
