From b25edc42bfb9602f0503474b2c94701d5536ce60 Mon Sep 17 00:00:00 2001 From: Deepthi Dharwar Date: Fri, 28 Oct 2011 16:20:24 +0530 Subject: cpuidle: Remove CPUIDLE_FLAG_IGNORE and dev->prepare() The cpuidle_device->prepare() mechanism causes updates to the cpuidle_state[].flags, setting and clearing CPUIDLE_FLAG_IGNORE to tell the governor not to chose a state on a per-cpu basis at run-time. State demotion is now handled by the driver and it returns the actual state entered. Hence, this mechanism is not required. Also this removes per-cpu flags from cpuidle_state enabling it to be made global.
