From 6ec70ebfccd31ae3668d99b5703e5c9ce38384b4 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Thu, 25 Apr 2013 00:24:06 +0200
Subject: [PATCH 06/13] MIPS: BCM63XX: append cpu number to irq_{stat,mask}*

For SMP affinity support we need to discrimnate between the registers
for both CPUs.
