    Subject[PATCH 08/11] ACPI: processor: change acpi_processor_eval_pdc interface
    From
    Date
    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.
