    So a better question would be: What's the purpose of ->stop() call for a policy?
    Stop managing CPUs of that policy? Or even do something on CPUs of a policy
    before CPUs are offlined?

    Probably in the current solution Dirk is doing both these things..

    And so I thought maybe its better not to restrict ->stop() to just
    setpolicy() drivers.
