[merged mm-stable] mm-convert-vma_lookup-to-use-mtree_load.patch removed from -mm tree

[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm: convert vma_lookup() to use mtree_load()
has been removed from the -mm tree.  Its filename was
     mm-convert-vma_lookup-to-use-mtree_load.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

Unlike the rbtree, the Maple Tree will return a NULL if there's nothing at
a particular address.

Since the previous commit dropped the vmacache, it is now possible to
consult the tree directly.
