Subject: copy_process(): remove the unneeded clear_tsk_thread_flag(TIF_SIGPENDING)
From: Oleg Nesterov <oleg@xxxxxxxxxx>
The forked child can have TIF_SIGPENDING if it was copied from parent's
ti->flags. But this is harmless and actually almost never happens,
because copy_process() can't succeed if signal_pending() == T.
