From b675eeb743abaa0b99a35c1fd32fea8e13a17d32 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Tue, 14 Feb 2012 11:40:55 +0000 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.
