From cc81d7f37273ccb34db99a1f7ce688953a04289d Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Sat, 12 Jul 2014 12:49:36 +0200 Subject: [PATCH] MIPS: BCM63xx: Append irq line to irq_{stat,mask}* The SMP capable irq controllers have two interrupt output pins which are controlled through separate registers, so make the variables arrays.
