Commit d290ef93 authored by Linus Torvalds's avatar Linus Torvalds

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)"

* tag 'acpi-4.18-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPICA: Recognize the _OSI string "Windows 2017.2"
  ACPICA: Update version to 20180531
  ACPICA: Interpreter: Begin deprecation of Unload operator
  ACPICA: AML parser: attempt to continue loading table after error
  ACPICA: Debugger: Reduce verbosity for module-level code errors.
  ACPICA: AML Parser: Add debug option to dump parse trees
  ACPICA: Debugger: Add count of namespace nodes after namespace dump
  ACPICA: IORT: Add PMCG node supprt
  ACPICA: IORT: Update for revision D
  ACPI / Documentation: update ACPI customize method feature docs
