Linus Torvalds 6a8d7fbf1c More ACPI updates for 5.17-rc1 
- Add support for the the Platform Firmware Runtime Update and
    Telemetry (PFRUT) interface based on ACPI to allow certain pieces
    of the platform firmware to be updated without restarting the
    system and to provide a mechanism for collecting platform firmware
    telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).
 
  - Ignore E820 reservations covering PCI host bridge windows on
    sufficiently recent x86 systems to avoid issues with allocating
    PCI BARs on systems where the E820 reservations cover the entire
    PCI host bridge memory window returned by the _CRS object in the
    system's ACPI tables (Hans de Goede).
 
  - Fix and clean up acpi_scan_init() (Rafael Wysocki).
 
  - Add more sanity checking to ACPI SPCR tables parsing (Mark
    Langsdorf).
 
  - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
 
  - Drop unnecessary "static" from the ACPI PCC address space handling
    driver added recently (kernel test robot).

Merge tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more ACPI updates from Rafael Wysocki:
 "The most significant item here is the Platform Firmware Runtime Update
  and Telemetry (PFRUT) support designed to allow certain pieces of the
  platform firmware to be updated on the fly, among other things.

  Also important is the e820 handling change on x86 that should work
  around PCI BAR allocation issues on some systems shipping since 2019.

  The rest is just a handful of assorted fixes and cleanups on top of
  the ACPI material merged previously.

  Specifics:

   - Add support for the the Platform Firmware Runtime Update and
     Telemetry (PFRUT) interface based on ACPI to allow certain pieces
     of the platform firmware to be updated without restarting the
     system and to provide a mechanism for collecting platform firmware
     telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).

   - Ignore E820 reservations covering PCI host bridge windows on
     sufficiently recent x86 systems to avoid issues with allocating PCI
     BARs on systems where the E820 reservations cover the entire PCI
     host bridge memory window returned by the _CRS object in the
     system's ACPI tables (Hans de Goede).

   - Fix and clean up acpi_scan_init() (Rafael Wysocki).

   - Add more sanity checking to ACPI SPCR tables parsing (Mark
     Langsdorf).

   - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).

   - Drop unnecessary "static" from the ACPI PCC address space handling
     driver added recently (kernel test robot)"
