Is it possible somehow to provide a kind of wrapper/backup function:
trace_power_frequency_cpu(POWER_PSTATE, frequency, cpu);
or another trace interface with eventually some more overhead?
Then it should be easy to support all drivers.
Otherwise you'll for example miss the pcc driver which supports
latest/upcoming Intel CPUs and which does IO based switching which needs not
to run on the cpu that gets switched.
