[PATCH v3 0/2] mm/hmm: A fix and a selftest

[Dev Jain]

Patch 1 fixes a stale warning present from the time when only migration
softleaf entries were supported at the PMD level.

Patch 2 adds some code into hmm-tests.c which exercises the pagemap path
for PMD device-private entries.

---
Applies on mm-unstable (d17fe8a046a2).

v2->v3:
 - Use MADV_COLLAPSE, use PAGEMAP_PRESENT

v1->v2:
 - Add test

Dev Jain (2):
  fs/proc/task_mmu: do not warn on seeing non-migration pmd entry

    entries
