Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the 20210604 upstream
  revision, add preliminary support for the Platform Runtime Mechanism
  (PRM), address issues related to the handling of device dependencies
  in the ACPI device eunmeration code, improve the tracking of ACPI
  power resource states, improve the ACPI support for suspend-to-idle on
  AMD systems, continue the unification of message printing in the ACPI
  code, address assorted issues and clean up the code in a number of
  places.

  Specifics:

   - Update ACPICA code in the kernel to upstrea revision 20210604
     including the following changes:

      - Add defines for the CXL Host Bridge Structureand and add the
        CFMWS structure definition to CEDT (Alison Schofield).
      - iASL: Finish support for the IVRS ACPI table (Bob Moore).
      - iASL: Add support for the SVKL table (Bob Moore).
      - iASL: Add full support for RGRT ACPI table (Bob Moore).
      - iASL: Add support for the BDAT ACPI table (Bob Moore).
      - iASL: add disassembler support for PRMT (Erik Kaneda).
      - Fix memory leak caused by _CID repair function (Erik Kaneda).
      - Add support for PlatformRtMechanism OpRegion (Erik Kaneda).
      - Add PRMT module header to facilitate parsing (Erik Kaneda).
      - Add _PLD panel positions (Fabian Wüthrich).
      - MADT: add Multiprocessor Wakeup Mailbox Structure and the SVKL
        table headers (Kuppuswamy Sathyanarayanan).
      - Use ACPI_FALLTHROUGH (Wei Ming Chen).

   - Add preliminary support for the Platform Runtime Mechanism (PRM) to
     allow the AML interpreter to call PRM functions (Erik Kaneda).

   - Address some issues related to the handling of device dependencies
     reported by _DEP in the ACPI device enumeration code and clean up
     some related pieces of it (Rafael Wysocki).

   - Improve the tracking of states of ACPI power resources (Rafael
     Wysocki).

   - Improve ACPI support for suspend-to-idle on AMD systems (Alex
     Deucher, Mario Limonciello, Pratik Vishwakarma).

   - Continue the unification and cleanup of message printing in the
     ACPI code (Hanjun Guo, Heiner Kallweit).

   - Fix possible buffer overrun issue with the description_show() sysfs
     attribute method (Krzysztof Wilczyński).

   - Improve the acpi_mask_gpe kernel command line parameter handling
     and clean up the core ACPI code related to sysfs (Andy Shevchenko,
     Baokun Li, Clayton Casciato).

   - Postpone bringing devices in the general ACPI PM domain to D0
     during resume from system-wide suspend until they are really needed
     (Dmitry Torokhov).

   - Make the ACPI processor driver fix up C-state latency if not
     ordered (Mario Limonciello).

   - Add support for identifying devices depening on the given one that
     are not its direct descendants with the help of _DEP (Daniel
     Scally).

   - Extend the checks related to ACPI IRQ overrides on x86 in order to
     avoid false-positives (Hui Wang).

   - Add battery DPTF participant for Intel SoCs (Sumeet Pawnikar).

   - Rearrange the ACPI fan driver and device power management code to
     use a common list of device IDs (Rafael Wysocki).

   - Fix clang CFI violation in the ACPI BGRT table parsing code and
     clean it up (Nathan Chancellor).

   - Add GPE-related quirks for some laptops to the EC driver (Chris
     Chiu, Zhang Rui).

   - Make the ACPI PPTT table parsing code populate the cache-id value
     if present in the firmware (James Morse).

   - Remove redundant clearing of context->ret.pointer from
     acpi_run_osc() (Hans de Goede).

   - Add missing acpi_put_table() in acpi_init_fpdt() (Jing Xiangfeng).

   - Make ACPI APEI handle ARM Processor Error CPER records like Memory
     Error ones to avoid user space task lockups (Xiaofei Tan).

   - Stop warning about disabled ACPI in APEI (Jon Hunter).

   - Fix fall-through warning for Clang in the SBSHC driver (Gustavo A.
     R. Silva).

   - Add custom DSDT file as Makefile prerequisite (Richard Fitzgerald).

   - Initialize local variable to avoid garbage being returned (Colin
     Ian King).

   - Simplify assorted pieces of code, address assorted coding style and
     documentation issues and comment typos (Baokun Li, Christophe
     JAILLET, Clayton Casciato, Liu Shixin, Shaokun Zhang, Wei Yongjun,
     Yang Li, Zhen Lei)"
