PM: Introduce Intel PowerClamp Driver
Intel PowerClamp driver performs synchronized idle injection across all online CPUs. The goal is to maintain a given package level C-state ratio. Compared to other throttling methods already exist in the kernel, such as ACPI PAD (taking CPUs offline) and clock modulation, this is often more efficient in terms of performance per watt. Please refer to Documentation/thermal/intel_powerclamp.txt for more details. Signed-off-by:Arjan van de Ven <arjan@linux.intel.com> Signed-off-by:
