funny. not to mention that it was not the only argument I presented but please
tell us explicitly what's your reason to blow out kernel footprint by the code
which can be handled outside the kernel. I'd prefer to see technical reasons a
kind of latencies, etc but not the constant refrain "don't touch cpufreq
interface". Especially considering that proposed improvements _do_ _not_
_change_ the interface.

And just FYI kernel footprint was stated as one of main current issues at least
on the last OLS.
