Pull ACPI updates from Rafael Wysocki:
 "These mostly update the ACPICA code in the kernel to upstream revision
  20170531 which covers all of the new material from ACPI 6.2, including
  new tables (WSMT, HMAT, PPTT), new subtables and definition changes
  for some existing tables (BGRT, HEST, SRAT, TPM2, PCCT), new resource
  descriptor macros for pin control, support for new predefined methods
  (_LSI, _LSR, _LSW, _HMA), fixes and cleanups.

  On top of that, an additional ACPICA change from Kees (which also is
  upstream already) switches all of the definitions of function pointer
  structures in ACPICA to use designated initializers so as to make the
  structure layout randomization GCC plugin work with it.

  The rest is a few fixes and cleanups in the EC driver, an xpower PMIC
  driver update, a new backlight blacklist entry, and update of the
  tables configfs interface and a messages formatting cleanup.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision revision
     20170531 (which covers all of the new material from ACPI 6.2)
     including:
      * Support for the PinFunction(), PinConfig(), PinGroup(),
        PinGroupFunction(), and PinGroupConfig() resource descriptors
        (Mika Westerberg).
      * Support for new subtables in HEST and SRAT, new notify value for
        HEST, header support for TPM2 table changes, and BGRT Status
        field update (Bob Moore).
      * Support for new PCCT subtables (David Box).
      * Support for _LSI, _LSR, _LSW, and _HMA as predefined methods
        (Erik Schmauss).
      * Support for the new WSMT, HMAT, and PPTT tables (Lv Zheng).
      * New UUID values for Processor Properties (Bob Moore).
      * New notify values for memory attributes and graceful shutdown
        (Bob Moore).
      * Fix related to the PCAT_COMPAT MADT flag (Janosch Hildebrand).
      * Resource to AML conversion fix for resources containing GPIOs
        (Mika Westerberg).
      * Disassembler-related updates (Bob Moore, David Box, Erik
        Schmauss).
      * Assorted fixes and cleanups (Bob Moore, Erik Schmauss, Lv Zheng,
        Cao Jin).

   - Modify ACPICA to always use designated initializers for function
     pointer structures to make the structure layout randomization GCC
     plugin work with it (Kees Cook).

   - Update the tables configfs interface to unload SSDTs on configfs
     entry removal (Jan Kiszka).

   - Add support for the GPI1 regulator to the xpower PMIC Operation
     Region handler (Hans de Goede).

   - Fix ACPI EC issues related to conflicting EC definitions in the
     ECDT and in the ACPI namespace (Lv Zheng, Carlo Caione, Chris
     Chiu).

   - Fix an interrupt storm issue in the EC driver and make its debug
     output work with dynamic debug as expected (Lv Zheng).

   - Add ACPI backlight quirk for Dell Precision 7510 (Shih-Yuan Lee).

   - Fix whitespace in pr_fmt() to align log entries properly in some
     places in the ACPI subsystem (Vincent Legoll)"
