PowerCap: Add class driver The power capping framework providing a consistent interface between the kernel and user space that allows power capping drivers to expose their settings to user space in a uniform way. The overall design of the framework is described in the documentation added by the previous patch in this series.

intel_rapl: abstract RAPL common code Split intel_rapl.c to intel_rapl_common.c and intel_rapl_msr.c, where intel_rapl_common.c contains the common code that can be used by both MSR and MMIO interface. intel_rapl_msr.c contains the implementation of RAPL MSR interface.

powercap / idle_inject: Add an idle injection framework Initially, the cpu_cooling device for ARM was changed by adding a new policy inserting idle cycles. The intel_powerclamp driver does a similar action. Instead of implementing idle injections privately in the cpu_cooling device, move the idle injection code in a dedicated framework and give the opportunity to other frameworks to make use of it. The framework relies on the smpboot kthreads which handles via its main loop the common code for hotplugging and [un]parking. This code was previously tested with the cpu cooling device and went through several iterations. It results now in split code and API exported in the header file. It was tested with the cpu cooling device with success.
