Normally, I would appreciate this split of the patches, but since
these are material for stable kernels I decided to squash the patches.
I also took the opportunity of updating the commit message a bit and
did a minor cleanup in the code. Please have a look at my next branch
and yell at me if there is something you don't like.
So, applied for next and by adding a stable tag, thanks!
Kind regards
