coredump: fix the setting of PF_DUMPCORE
Commit 079148b9 ("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. Signed-off-by:Silesh C V <svellattu@mvista.com> Acked-by:
