This adds the CPUFreq driver for mobile AMD Opteron/Athlon64
processors.
+ An acpi interface is available if acpi support has been selected.
+ This is required for multi-socket and other systems but not
necessarily required for UP single socket systems.
For details, take a look at <file:Documentation/cpu-freq/>.
If in doubt, say N.

+ This provides access to the acpi tables for full p-state
functionality. This driver is also required
+ for cpufreq to work with multi-socket and other smp systems.

+ It is safe to say Y here.
default y
