Yeah, this is the kind of completely unacceptable stuff that I was
_afraid_ I'd get from the hmm tree, but didn't.

It's not just "mm helpers". It's core changes like changing how
do_page_mkwrite() works. With not a single ack or review from any of
the VM people.

Maybe that commit is fine. But there's a whole slew of questionable
core VM changes there, and absolutely none of them look obvious, and
none of them hack acks from any of the VM people.

The hmm tree looked like good cleanups that largely removed broken code.

This looks like it *adds* broken code, or at least adds code that had
absolutely no real review outside of vmware.

I'm not pulling this. Why did you merge it into your tree, when
apparently you were aware of how questionable it is judging by the drm
pull request.
