Merge branch 'intel_idle+acpi'
Merge changes updating the ACPI processor driver in order to export acpi_processor_evaluate_cst() to the code outside of it and adding ACPI support to the intel_idle driver based on that. * intel_idle+acpi: Documentation: admin-guide: PM: Add intel_idle document intel_idle: Use ACPI _CST on server systems intel_idle: Add module parameter to prevent ACPI _CST from being used intel_idle: Allow ACPI _CST to be used for selected known processors cpuidle: Allow idle states to be disabled by default intel_idle: Use ACPI _CST for processor models without C-state tables intel_idle: Refactor intel_idle_cpuidle_driver_init() ACPI: processor: Export acpi_processor_evaluate_cst() ACPI: processor: Make ACPI_PROCESSOR_CSTATE depend on ACPI_PROCESSOR ACPI: processor: Clean up acpi_processor_evaluate_cst() ACPI: processor: Introduce acpi_processor_evaluate_cst() ACPI: processor: Export function to claim _CST control
