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.
