    Subject[PATCH] copy_process: remove the unneeded clear_tsk_thread_flag(TIF_SIGPENDING)
    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.
