From 817deb05df45577d4037230f2facee486c11d9df Mon Sep 17 00:00:00 2001 From: Deepthi Dharwar Date: Wed, 3 Oct 2012 18:42:10 +0000 Subject: [PATCH] cpuidle/powerpc: Fix target residency initialisation in pseries cpuidle Remove the redundant target residency initialisation in pseries_cpuidle_driver_init(). This is currently over-writing the residency time updated as part of the static table, resulting in all the idle states having the same target residency of 100us which is incorrect. This may result in the menu governor making wrong state decisions.
