ACPI: processor: change acpi_processor_eval_pdc interface
acpi_processor_eval_pdc() really only needs a handle and an acpi_object_list * to do its work. No need to pass in a struct acpi_processor *, so let's be more specific about what we want. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
