You're right AFAICS. For governors other than schedutil fixing that would be a matter of adding a !CONFIG_SMP variant of update_load_avg() that will call cpufreq_update_util() and do nothing else. It doesn't matter what is passed via util and max then. In turn, schedutil should probably depend on CONFIG_SMP. Peter?
