The quilt patch titled
Subject: mm: make mmap_region() internal
has been removed from the -mm tree. Its filename was
mm-make-mmap_region-internal.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

Now that we have removed the one user of mmap_region() outside of mm, make it internal and add it to vma.c so it can be userland tested.

This ensures that all external memory mappings are performed using the appropriate interfaces and allows us to modify memory mapping logic as we see fit.

Additionally expand test stubs to allow for the mmap_region() code to compile and be userland testable.
