I agree: this is naturally the simplest and most consistent approach.
(And most of all, it is that especially for the kernel.)
In my opinion this would satisfy well the requirements of CPU frequency
scaling in NetBSD. But do we have strong cases in favor of the intermediate
values? As I see it, stepping always to the highest value when in load would
only trade some minor power consumption increase for simplicity.
