At present, MSR based Enhanced Speedstep Technology (EST) is handled by
speedstep-centrino.c. The attached patch adds more features to
speedstep-centrino, making it more generic. With these changes, it can
run on SMP systems which supports EST, based on the information provided
by ACPI. The non-ACPI (static table based) driver will still be UP only.
