The quilt patch titled
Subject: mm/mmap: convert do_brk_flags() to use vma_prepare() and vma_complete()
has been removed from the -mm tree. Its filename was
mm-mmap-convert-do_brk_flags-to-use-vma_prepare-and-vma_complete.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
