Subject: [PATCH] mm/migrate: remove folio_test_movable() and
 folio_movable_ops()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Folios will have nothing to do with movable_ops page migration.  These
functions are now unused, so let's remove them.

Note that __folio_test_movable() and friends will be removed separately
next, after more rework.
