Subject: [PATCH 25/28] m68k/sun3: Convert Sun3/3x to genirq
Date: Sun, 11 Sep 2011 13:59:51 +0200 [thread overview]
Message-ID: <1315742394-16036-26-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1315742394-16036-1-git-send-email-geert@linux-m68k.org>
Replace the custom irq handler that masks the irq and calls do_IRQ(), and
the unmasking in the individual handlers, by handle_level_irq().
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
