[PATCH 0/6] cpuidle : per cpu latencies

[Daniel Lezcano <daniel.lezcano@linaro.org>]

Since commit 46bcfad7a819bd17ac4e831b04405152d59784ab,
        cpuidle: Single/Global registration of idle states

we have a single registration for the cpuidle states which makes
sense. But now two new architectures are coming: tegra3 and big.LITTLE.

These architectures have different cpus with different caracteristics
for power saving. High load => powerfull processors, idle => small processors.

That implies different cpu latencies.

This patchset keeps the current behavior as introduced by Deepthi without
breaking the drivers and add the possibility to specify a per cpu states.

 * Tested on intel core 2 duo T9500
 * Tested on vexpress by Lorenzo Pieralsi
 * Tested on tegra3 by Peter De Schrijver

Daniel Lezcano (6):
  acpi : move the acpi_idle_driver variable declaration
  acpi : move cpuidle_device field out of the acpi_processor_power
    structure
  acpi : remove pointless cpuidle device state_count init
  cpuidle : add a pointer for cpuidle_state in the cpuidle_device
  cpuidle : use per cpuidle device cpu states
  cpuidle : add cpuidle_register_states function
