The "anomalies" need to be investigated.
The patches need to be re-based for onto 3.16RC1 Plus Dirk's patch's (my patch 3 first and on it's own (done and accpeted)).
With the change so that "intel_pstate_get_scaled_busy" is only called once, the C0 stuff should go in there instead.

There have also been anomalies using kernel 3.16 RC1 (before doug mods). The anomalies appear to be less frequent, which is not understood. (I do not have a seperate web page yet.)

Histogram of the time between calls to the intel_pstate driver for run s316rc1_03. The graphs are actually pretty useless because we do not know when a long deferral is due to a truely idle CPU or a mistake.
