[PATCH] Direct Migration V9: remove_from_swap() to remove swap ptes
Add remove_from_swap remove_from_swap() allows the restoration of the pte entries that existed before page migration occurred for anonymous pages by walking the reverse maps. This reduces swap use and establishes regular pte's without the need for page faults.
