    Subject[PATCH 16/40] microblaze: No need to reset handler if SA_ONESHOT
    Date
    From: Matt Fleming <matt.fleming@intel.com>

    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.
