Merge tag 'acpi-4.18-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull additional ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to upstream revision
  20180531 including one important AML parser fix and updates related to
  the IORT table, make the kernel recognize the "Windows 2017.2" _OSI
  string and update the customized methods documentation.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20180531
     including:
      * AML parser fix to continue loading tables after detecting an AML
        error (Erik Schmauss).
      * AML parser debug option to dump parse trees (Bob Moore).
      * Debugger updates (Bob Moore).
      * Initial bits of Unload () operator deprecation (Bob Moore).
      * Updates related to the IORT table (Robin Murphy).

   - Make Linux respond to the "Windows 2017.2" _OSI string which
     allows native Thunderbolt enumeration to be used on Dell systems
     and was unsafe before recent changes in the PCI subsystem (Mario
     Limonciello)

   - Update the ACPI method customization feature documentation (Erik
     Schmauss)"
