From 8b78cf602fd3bd97c0080edd22fe8fd5d0fa7832 Mon Sep 17 00:00:00 2001 From: Yi Yang Date: Mon, 25 Feb 2008 08:46:12 +0800 Subject: cpuidle: fix cpuidle time and usage overflow cpuidle C-state sysfs node time and usage are very easy to overflow because they are all of unsigned int type, time will overflow within about two hours, usage will take longer time to overflow, but they are increasing for ever. This patch will convert them to unsigned long long.
