From: Deepthi Dharwar Date: Wed, 3 Oct 2012 18:42:10 +0000 (+0000) Subject: cpuidle/powerpc: Fix target residency initialisation in pseries cpuidle X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=817deb05df45577d4037230f2facee486c11d9df;p=openwrt%2Fstaging%2Fblogic.git 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.
