Pull ACPI updates from Rafael Wysocki:
 "These include a usual ACPICA code update (this time to upstream
  revision 20170728), a fix for a boot crash on some systems with
  Thunderbolt devices connected at boot time, a rework of the handling
  of PCI bridges when setting up device wakeup, new support for Apple
  device properties, support for DMA configurations reported via ACPI on
  ARM64, APEI-related updates, ACPI EC driver updates and assorted minor
  modifications in several places.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20170728
     including:
      * Alias operator handling update (Bob Moore).
      * Deferred resolution of reference package elements (Bob Moore).
      * Support for the _DMA method in walk resources (Bob Moore).
      * Tables handling update and support for deferred table
        verification (Lv Zheng).
      * Update of SMMU models for IORT (Robin Murphy).
      * Compiler and disassembler updates (Alex James, Erik Schmauss,
        Ganapatrao Kulkarni, James Morse).
      * Tools updates (Erik Schmauss, Lv Zheng).
      * Assorted minor fixes and cleanups (Bob Moore, Kees Cook, Lv
        Zheng, Shao Ming).

   - Rework the initialization of non-wakeup GPEs with method handlers
     in order to address a boot crash on some systems with Thunderbolt
     devices connected at boot time where we miss an early hotplug event
     due to a delay in GPE enabling (Rafael Wysocki).

   - Rework the handling of PCI bridges when setting up ACPI-based
     device wakeup in order to avoid disabling wakeup for bridges
     prematurely (Rafael Wysocki).

   - Consolidate Apple DMI checks throughout the tree, add support for
     Apple device properties to the device properties framework and use
     these properties for the handling of I2C and SPI devices on Apple
     systems (Lukas Wunner).

   - Add support for _DMA to the ACPI-based device properties lookup
     code and make it possible to use the information from there to
     configure DMA regions on ARM64 systems (Lorenzo Pieralisi).

   - Fix several issues in the APEI code, add support for exporting the
     BERT error region over sysfs and update APEI MAINTAINERS entry with
     reviewers information (Borislav Petkov, Dongjiu Geng, Loc Ho, Punit
     Agrawal, Tony Luck, Yazen Ghannam).

   - Fix a potential initialization ordering issue in the ACPI EC driver
     and clean it up somewhat (Lv Zheng).

   - Update the ACPI SPCR driver to extend the existing XGENE 8250
     workaround in it to a new platform (m400) and to work around an
     Xgene UART clock issue (Graeme Gregory).

   - Add a new utility function to the ACPI core to support using ACPI
     OEM ID / OEM Table ID / Revision for system identification in
     blacklisting or similar and switch over the existing code already
     using this information to this new interface (Toshi Kani).

   - Fix an xpower PMIC issue related to GPADC reads that always return
     0 without extra pin manipulations (Hans de Goede).

   - Add statements to print debug messages in a couple of places in the
     ACPI core for easier diagnostics (Rafael Wysocki).

   - Clean up the ACPI processor driver slightly (Colin Ian King, Hanjun
     Guo).

   - Clean up the ACPI x86 boot code somewhat (Andy Shevchenko).

   - Add a quirk for Dell OptiPlex 9020M to the ACPI backlight driver
     (Alex Hung).

   - Assorted fixes, cleanups and updates related to ACPI (Amitoj Kaur
     Chawla, Bhumika Goyal, Frank Rowand, Jean Delvare, Punit Agrawal,
     Ronald Tschalär, Sumeet Pawnikar)"
