This series is posted for posterity. It has been NAK'd by the community since CPU hotplug has been deemed an inappropriate mechanism for power capping.
I spoke with Amit about this last week. What's the plan going forward on really saving power when a CPU isn't being used -- just ensuring the lowest possible idle state is really off?
And are there situations where the hardware requires something like hotplug to actually maximize savings?
Oh, and finally, it seems that patches 1-3 might be useful, regardless of the NAKing of the actual patchset, right?
