Several CPU_FREQ options need ACPI_PROCESSOR interfaces to build.

Hmm, it should be optional. Ie, if you don't have ACPI enabled, you should still be able to use these drivers (the k7 one at least), you just won't be able to use the ACPI fallback.

Hm, I see what you mean, but how do we handle source files that call an optional kernel API (depending on CONFIG_xyz)?

IOW, building a cpufreq driver in-kernel that wants to call acpi_processor_register_performance(), where CONFIG_ACPI_PROCESSOR=m, needs to be prevented....
