For some reason I see increased CPU utilization with this patch series (75% -> 85%) with the same rate of requests being handled by the vanilla kernel and a kernel with these patches applied.
I am running a bisect in the series to see what change could possibly cause that, and also digging through system statistics to see whether it might be something as perverse as not mistakenly choosing deeper C-states on one core causing other cores to miss out on turbo mode...
