Subject: mm/mempolicy: convert queue_pages_pte_range() to queue_folios_pte_range()
Date: Mon, 23 Jan 2023 17:22:07 -0800

This function now operates on folios associated with ptes instead of
pages.

This change is in preparation for the conversion of queue_pages_required()
to queue_folio_required() and migrate_page_add() to migrate_folio_add().
