From dda7535912255015ecf7264c1d6691a09f8ba487 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 18 Aug 2011 14:46:46 +0200 Subject: [PATCH] m68k/sun3: Convert Sun3/3x to genirq Replace the custom irq handler that masks the irq and calls do_IRQ(), and the unmasking in the individual handlers, by handle_level_irq().
