Thank you for your good work and the benchmark. I hope you will continue
to use it and report some issues. I am going to send a follow up patches
for the DMC and I will add your 'Reported-by'. In the tests I can see
the improvements, but it's worth to consult with you if I understand
the new results correctly.

I think there is still some area for improvements in the devfreq and you
could find the interesting bits to contribute.
