ACPI: processor: change acpi_processor_set_pdc() interface
When calling _PDC, we really only need the handle to the processor to call the method; we don't look at any other parts of the struct acpi_processor * given to us. In the early path, when we walk the namespace, we are given the handle directly, so just pass it through to acpi_processor_set_pdc() without stuffing it into a wasteful struct acpi_processor allocated on the stack each time This saves 2834 bytes of stack. Update the interface accordingly. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
