I now created one big commit which I'm planning to take to
wireless-drivers-next:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next.git/commit/?h=pending&id=80b361279546ca7a57c7e7844c2e23f474f9852d

Please double check that I didn't break anything while squashing the
patches. I tried to be careful, but you never know.
