There are a number of files which don't quite belong anywhere else, so

elsewhere we can update incrementally but it is preferable that we assign
each file to a section as best we can.

REVIEWERS - let me know if these seem appropriate, I'm eyeballing
this. even if they are not quite best placed a 'best effort' is still
worthwhile so we establish a place to put all mm files, we can always
incrementally update these later.

Probably better to have some section than none ... was just briefly wondering if "CORE" is the right section for some of that. Some of that might be better of in a "MM MISC" section, maybe.

Wondering if there should be a MM DEBUG section. But then, no idea who in their right mind would be willing to maintain that ;)

Smells like reclaim/memcg.

memory hotplug related. Well, one could argue that it's just a memory hotplug user. It's mostly ZONE_DEVICE handling. Wonder if that would be
worth a separate section ...

This contains quite some meat. I wonder if a OOM section would be appropriate (Michal, I'm looking at you :) )
