Merge tag 'acpi-5.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull additional ACPI updates from Rafael Wysocki:
 "These close a nasty race condition in the ACPI memory mappings
  management code and an invalid parameter check in a library routing,
  allow GPE 0xFF to be masked via kernel command line, add a new lid
  switch blacklist entry and clean up Kconfig.

  Specifics:

   - Fix locking issue in acpi_os_map_cleanup() leading to a race
     condition that can be harnessed for provoking a kernel panic from
     user space (Francesco Ruggeri)

   - Fix parameter check in acpi_bus_get_private_data() (Vamshi K
     Sthambamkadi)

   - Allow GPE 0xFF to be masked via kernel command line (Yunfeng Ye)

   - Add a new lid switch blacklist entry for Acer Switch 10 SW5-032 to
     the ACPI button driver (Hans de Goede)

   - Clean up Kconfig (Krzysztof Kozlowski)"
