[merged mm-stable] mm-mlock-drop-dead-code-in-count_mm_mlocked_page_nr.patch removed from -mm tree

[Andrew Morton]

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

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().
