From b54992fe1b4bad7b7488d58b8696e4e8974fdab0 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 15 Nov 2010 14:46:46 +0000 Subject: ARM: SMP: collect IPI and local timer IRQs for /proc/stat The IPI and local timer interrupts weren't being properly accounted for in /proc/stat. Collect them from the irq_stat structure, and return their sum.
