Thanks for you hint about turbostat. As you most probably understood, I'm individual amateur kernel developer. I could provide some numbers from x86 architecture as Rafael suggested. But unfortunately, I don't have access to more sources/infrastructure. So, I will not be able to provide numbers from different platform(s). I've already provided some benchmarks from x86 (3.10-rc3) and also tested the patch in 3.4.47 kernel (ARM, Nexus 4 phone, ~1000 installations) and in 3.0.80 kernel (ARM, Samsung Galaxy S phone, ~1500 installations). Kindly let me know if "couple of platforms/vendors" is a show stopper for this patch series. If yes, please ignore this patch and accept my apologies for wasting your time. I am just trying to contribute on this project (I believe there is space here for amateur developers). Many thanks to Rafael who helped me and guide me. Thanks to Viresh for his helpful comments and his acknowledgment for the patch.
