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.
