The patch titled
Subject: mm: set task exit code before complete_vfork_done()
has been removed from the -mm tree. Its filename was
mm-correctly-synchronize-rss-counters-at-exit-exec-set-task-exit-code-before-complete_vfork_done.patch
This patch was dropped because it was folded into mm-correctly-synchronize-rss-counters-at-exit-exec.patch
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

From: Konstantin Khlebnikov <khlebnikov@xxxxxxxxxx>
Subject: mm: set task exit code before complete_vfork_done()
kthread_stop() uses task->vfork_done for synchronization. The exiting
kthread shouldn't do complete_vfork_done() until it sets ->exit_code.
fix for mm-correctly-synchronize-rss-counters-at-exit-exec.patch
