I went over the whole set once again and did not find any real issues. As
the outstanding review comments are addressed, I decided that only broader
exposure can shake out eventually remaining issues. Applied and pushed out,
so it should show up in linux-next soon.

The mm regression seems to be sorted, so there is no immeditate fallout
expected.

Thanks for your patience in reworking this over and over. Thanks to Andy
for putting his entry focssed eyes on it more than once. Great work!

Thanks,
