migrate.c really contains two things: the traditional page migration
code implementing aops ->migrate semantics, and migrate_vma and its
callbacks. The first part is broader, the second part is hmm specific
(and should probably have been in a file of its own, given that it is
guarded off CONFIG_MIGRATE_VMA_HELPER). This series only touched the
latter part.
