Hmmm...seems we can remove this knob completely.
Peter,
Do you prefer to keep it or remove it completely ?
I prefer to keep it, the 'we can remove it' is true for all feature bits, they should never be twiddled in normal circumstances, its a debug feature. As such it makes sense to allow disabling the arch cpu-power fiddling.
