Subject: Revert "mm: rename alloc_demote_folio to alloc_migrate_folio"
Date: Mon, 16 Jun 2025 10:23:45 -0700

This reverts commit 8f75267d22bdf8e3baf70f2fa7092d8c2f58da71.

Commit 8f75267d22bd ("mm: rename alloc_demote_folio to
alloc_migrate_folio") was to reflect the fact the function is called for
not only demotion, but also general migrations from
DAMOS_MIGRATE_{HOT,COLD}.  The previous commit made the DAMOS actions to
not use alloc_migrate_folio(), though.  So, demote_folio_list() is the
only caller of alloc_migrate_folio(), and the name could now be rather
confusing.  Revert the renaming commit.
