The patch titled Subject: OpenRISC: no need to reset handler if SA_ONESHOT has been removed from the -mm tree. Its filename was openrisc-no-need-to-reset-handler-if-sa_oneshot.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/ ------------------------------------------------------ From: Matt Fleming <matt.fleming@xxxxxxxxx> Subject: OpenRISC: no need to reset handler if SA_ONESHOT get_signal_to_deliver() already resets the signal handler if SA_ONESHOT is set in ka->sa.sa_flags, there's no need to do it again in handle_signal(). Furthermore, because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]) instead of sighand->action[] the original code actually had no effect on signal delivery.
