From 707827f3387d9b260d50fa697885a4042cea3bf4 Mon Sep 17 00:00:00 2001 From: Deepthi Dharwar Date: Wed, 30 Nov 2011 02:46:42 +0000 Subject: powerpc/cpuidle: cpuidle driver for pSeries This patch implements a back-end cpuidle driver for pSeries based on pseries_dedicated_idle_loop and pseries_shared_idle_loop routines. The driver is built only if CONFIG_CPU_IDLE is set. This cpuidle driver uses global registration of idle states and not per-cpu.
