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...
