Subject: mm/damon/paddr: implement damon_folio_mkold()
Date: Fri, 26 Apr 2024 12:52:41 -0700

damon_pa_mkold() receives physical address, get the folio covering the
address, and makes the folio as old.  A following commit will reuse the
internal logic for marking a given folio as old.  To avoid duplication of
the code, split the internal logic.  Also, change the rmap walker
function's name from __damon_pa_mkold() to damon_folio_mkold_one(),
following the change of the caller's name and the naming rule that more
commonly used by other rmap walkers.
