We're talking about "dev_pagemap related cleanups v4", yes?

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. 
Perhaps something has gone wrong here.

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!
