      * Support for new Generic Affinity Structure subtable in SRAT
        (Erik Schmauss).
      * New PCC operation region support (Erik Schmauss).
      * Support for GICC statistical profiling for MADT (Erik Schmauss).
      * New Error Disconnect Recover notification support (Erik
        Schmauss).
      * New PPTT Processor Structure Flags fields support (Erik
        Schmauss).
      * ACPI 6.3 HMAT updates (Erik Schmauss).
      * GTDT Revision 3 support (Erik Schmauss).

        (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)

     Shevchenko)

   - Update the MAINTAINERS entry for APEI (Borislav Petkov)

   - Fix and clean up the ACPI EC driver (Rafael Wysocki, Zhang Rui)

   - Fix DMI checks handling in the ACPI backlight driver and add the
     "Lunch Box" chassis-type check to it (Hans de Goede)

   - Add support for using ACPI table overrides included in built-in
     initrd images (Shunyong Yang)

   - Update ACPI device enumeration to treat the PWM2 device as "always
     present" on Lenovo Yoga Book (Yauhen Kharuzhy)

   - Fix up the enumeration of device objects with the PRP0001 device ID
     (Andy Shevchenko)

   - Clean up PPTT parsing error messages (John Garry)

   - Clean up debugfs files creation handling (Greg Kroah-Hartman,
     Rafael Wysocki)

   - Clean up the ACPI DPTF Makefile (Masahiro Yamada)"
