mm: add folio_get_nontail_page()
Patch series "Convert a couple migrate functions to use folios", v2.
This patchset introduces folio_movable_ops() and converts 3 functions in
mm/migrate.c to use folios. It also introduces folio_get_nontail_page()
for folio conversions which may want to distinguish between head and tail
pages.
This patch (of 4):
folio_get_nontail_page() returns the folio associated with a head page.
This is necessary for folio conversions where the behavior of that
function differs between head pages and tail pages.
