        (Bob Moore).
      * Warning on creation of a zero-length opregion (Bob Moore).
      * acpiexec option to dump extra info for memory leaks (Bob Moore).
      * More ACPI error to firmware error conversions (Bob Moore).
      * Debugger fix (Bob Moore).
      * Copyrights update (Bob Moore)
