Help text

This determines whether the scaling_cur_freq sysfs attribute returns the last requested frequency or a more precise value based on hardware provided feedback (as architected counters). Given that a more precise frequency can now be provided via the cpuinfo_avg_freq attribute, by enabling this option, scaling_cur_freq maintains the provision of a counter based frequency, for compatibility reasons.
