The https://github.com/torvalds/linux/blob/3e732ebf7316ac83e8562db7e64cc68aec390a18/drivers/cpufreq/Makefile#L6 looks like the module in question wouldn't be built if CONFIG_CPU_FREQ_STAT is unset and according to output below it is indeed for me: ``` $ grep CPU_FREQ_STAT /boot/config-5.1* /boot/config-5.16.14-1-default:# CONFIG_CPU_FREQ_STAT is not set /boot/config-5.16.15-1-default:# CONFIG_CPU_FREQ_STAT is not set /boot/config-5.17.1-1-default:# CONFIG_CPU_FREQ_STAT is not set ```
