Pull more ACPI updates from Rafael Wysocki:
 "Here are new versions of two ACPICA changes that were deferred
  previously due to a problem they had introduced, two cleanups on top
  of them and the removal of a useless warning message from the ACPI
  core.

  Specifics:

   - Move some Linux-specific functionality to upstream ACPICA and
     update the in-kernel users of it accordingly (Lv Zheng)

   - Drop a useless warning (triggered by the lack of an optional
     object) from the ACPI namespace scanning code (Zhang Rui)"
