The patch titled
mips: use find_task_by_vpid in system calls
has been removed from the -mm tree. Its filename was
mips-use-find_task_by_vpid-in-system-calls.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: mips: use find_task_by_vpid in system calls
From: Pavel Emelyanov <xemul@xxxxxxxxxx>
There are some places left in mips, that lookup task in initial namespace,
while the code doing so gets the pid from the user space and thus must treat
it as virtual.
