From 4202735e8ab6ecfb0381631a0d0b58fefe0bd4e2 Mon Sep 17 00:00:00 2001 From: Deepthi Dharwar Date: Fri, 28 Oct 2011 16:20:33 +0530 Subject: cpuidle: Split cpuidle_state structure and move per-cpu statistics fields This is the first step towards global registration of cpuidle states. The statistics used primarily by the governor are per-cpu and have to be split from rest of the fields inside cpuidle_state, which would be made global i.e. single copy. The driver_data field is also per-cpu and moved.
