[PATCH v3] mm/thp: fix __split_huge_pmd_locked() for migration PMD
...ol group accounting assuming the page is mapped.
Also, if the PMD entry is a migration PMD entry, the call to
is_huge_zero_pmd(*pmd) is incorrect because it calls pmd_pfn(pmd) instead
of migration_entry_to_pfn(pmd_to_swp_entry(pmd)).
Fix these problems by checking for a PMD migration entry.

[PATCH v2 0/7] mm/hmm/nouveau: add THP migration to migrate_vma_*
This series adds support for transparent huge page migration to
migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers.
An earlier version was posted previously [1]. This version now
supports splitting a THP midway in the migration process which
led to a number of changes.
The patches apply cleanly to the current linux-mm tree. Since there
are a couple of patches in linux-mm from Dan
