I thought that both clusters being the same was questionable.

My main purpose with trying to get this merged is so that people using
Juno for general testing and validation will actually have cpuidle
running and so potentially find more bugs.

If we wait until ARM have finished tweaking their firmware and tuning
benchmark runs to get 'optimum' values for their main usecases then I
suspect we'll be waiting a long time ;-)
