3.13.11.6 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Silesh C V <svella...@mvista.com>
commit aed8adb7688d5744cb484226820163af31d2499a upstream.
Commit 079148b919d0 ("coredump: factor out the setting of PF_DUMPCORE")
cleaned up the setting of PF_DUMPCORE by removing it from all the
linux_binfmt->core_dump() and moving it to zap_threads().But this ended
up clearing all the previously set flags. This causes issues during
core generation when tsk->flags is checked again (eg. for PF_USED_MATH
to dump floating point registers). Fix this.
