In menuconfig, if you do not select:
Power management and ACPI options -> CPU Frequency scaling --> CPU Frequency scaling
You do not get a chance to select the various CPUFreq processor drivers either.
So, it seems reasonable to make these processor drivers:
- powernow-k8 - powernow-k7 - acpi-cpufreq
depend upon CONFIG_CPU_FREQ. This change allows us to be smarter with #ifdefs and symbols in generic ACPI header files later on.
