Subject: [PATCH 21/27] m68k/apollo: Convert Apollo to genirq
Date: Sun, 30 Oct 2011 13:48:29 +0100 [thread overview]
Message-ID: <1319978915-10933-22-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1319978915-10933-1-git-send-email-geert@linux-m68k.org>
Replace the custom user vector interrupt handler that calls do_IRQ() and
does an EOI by handle_fasteoi_irq().
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
