Add a P-state driver for the Intel Sandy bridge processor. In cpufreq terminology this driver implements a scaling driver with an internal governor. When built into the the kernel this driver will be the preferred scaling driver for Sandy bridge processors. In addition to the interfaces provided by the cpufreq subsystem for controlling scaling drivers. The user may control the behavior of the driver via three sysfs files located in "/sys/devices/system/cpu/intel_pstate". max_perf_pct: limits the maximum P state that will be requested by the driver stated as a percentage of the avail performance. min_perf_pct: limits the minimum P state that will be requested by the driver stated as a percentage of the avail performance. no_turbo: limits the driver to selecting P states below the turbo frequency range.
