[PATCH 0/4] hmm: fixes and documentations

[jglisse@redhat.com]

From: Jérôme Glisse <jglisse@redhat.com>

All patches only impact HMM user, there is no implication outside HMM.

First patch improve documentation to better reflect what HMM is. Second
patch fix #if/#else placement in hmm.h. The third patch add a call on
mm release which helps device driver who use HMM to clean up early when
a process quit. Finaly last patch modify the CPU snapshot and page fault
helper to simplify device driver. The nouveau patchset i posted last
week already depends on all of those patches.

You can find them in a hmm-for-4.17 branch:
