[PATCH 0/3] mm/hmm: fixes for device private page migration

[Ralph Campbell]

Testing the latest linux git tree turned up a few bugs with page
migration to and from ZONE_DEVICE private and anonymous pages.
Hopefully it clarifies how ZONE_DEVICE private struct page uses
the same mapping and index fields from the source anonymous page
mapping.

Patch #3 was sent earlier and this is v2 with an updated change log.
