Message

Rework to unify Huge/LRU/non-LRU folio isolation in do_migrate_range()
and isolate_migratepages_block(), then convert isolate_movable/lru_page()
to folio_isolate_movable/lru(), finally cleanup isolate_moveable/lru_page().

v2:
- rename isolate_movable_folio() to isolate_movable_folio() and address
  the issue about it, per Zi Yan, Vishal Moola
- check hwpoisoned page firstly in do_migrate_range(), which help
  to unify Hugepage/LRU/non-LRU movable folio isolation, suggested by
  Zi Yan
- re-order patches, per Vishal Moola.
