The quilt patch titled
Subject: mm/mlock: drop dead code in count_mm_mlocked_page_nr()
has been removed from the -mm tree. Its filename was
mm-mlock-drop-dead-code-in-count_mm_mlocked_page_nr.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/mlock: drop dead code in count_mm_mlocked_page_nr()

The check for mm being null has never been needed since the only caller
has always passed in current->mm. Remove the check from
count_mm_mlocked_page_nr().
