I note that linux-next contains "mm: remove the HMM config option" which was present in Christoph's v3 series but wasn't present in v4.

I think we are both caught off guard how big the conflict is! I guess I was distracted - I should have taken a look to see how mergable it all was. It's a large patchset and it appears to be mainly (entirely?) code cleanups. I don't think such material would be appropriate for a late -rc7 merge even if it didn't conflict with lots of other higher priority pending functional changes and fixes!
