The patch titled
Subject: exec: kill the unnecessary mm->def_flags setting in load_elf_binary()
has been removed from the -mm tree. Its filename was
exec-kill-the-unnecessary-mm-def_flags-setting-in-load_elf_binary.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alex Thorlton <athorlton@xxxxxxx>
Subject: exec: kill the unnecessary mm->def_flags setting in load_elf_binary()
load_elf_binary() sets current->mm->def_flags = def_flags and def_flags is
always zero. Not only this looks strange, this is unnecessary because
mm_init() has already set ->def_flags = 0.
