sh: cpuidle: Migrate off of hwblk API. 2011-11-18T07:13:09+00:00 Paul Mundt lethal@linux-sh.org 2011-11-18T07:13:09+00:00 4be887342c48f3b1e208bac6375c19c57791a3b9 Now that the hwblk API is unused and going away, migrate cpuidle off of it. This is a pretty straightforward migration given that we weren't really making use of the allowed mode overloading in the first place, so simply default to regular sleep mode.

cpuidle: Single/Global registration of idle states 2011-11-07T02:13:58+00:00 Deepthi Dharwar deepthi@linux.vnet.ibm.com 2011-10-28T10:50:42+00:00 46bcfad7a819bd17ac4e831b04405152d59784ab This patch makes the cpuidle_states structure global (single copy) instead of per-cpu. The statistics needed on per-cpu basis by the governor are kept per-cpu. This simplifies the cpuidle subsystem as state registration is done by single cpu only. Having single copy of cpuidle_states saves memory. Rare case of asymmetric C-states can be handled within the cpuidle driver and architectures such as POWER do not have asymmetric C-states. Having single/global registration of all the idle states, dynamic C-state transitions on x86 are handled by the boot cpu. Here, the boot cpu would disable all the devices, re-populate the states and later enable all the devices, irrespective of the cpu that would receive the notification first.
