#     Pull ACPI updates from Rafael Wysocki:
#      "These eliminate significant AML processing overhead related to using
#       operation regions in system memory, update the ACPICA code in the
#       kernel to upstream revision 20200717 (including a fix to prevent
#       operation region reference counts from overflowing in some cases),
#       remove the last bits of the (long deprecated) ACPI procfs interface
#       and do some assorted cleanups.
#     
#       Specifics:
#     
#        - Eliminate significant AML processing overhead related to using
#          operation regions in system memory by reworking the management of
#          memory mappings in the ACPI code to defer unmap operations (to do
#          them outside of the ACPICA locks, among other things) and making
#          the memory operation reagion handler avoid releasing memory
#          mappings created by it too early (Rafael Wysocki).
#     
#        - Update the ACPICA code in the kernel to upstream revision 20200717:
#     
#            * Prevent operation region reference counts from overflowing in
#              some cases (Erik Kaneda).
#     
#            * Replace one-element array with flexible-array (Gustavo A. R.
#              Silva).
#     
#        - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).
#     
#        - Drop last bits of the ACPI procfs interface (Thomas Renninger).
#     
#        - Drop some redundant checks from the code parsing ACPI tables
#          related to NUMA (Hanjun Guo).
#     
#        - Avoid redundant object evaluation in the ACPI device properties
#          handling code (Heikki Krogerus).
#     
#        - Avoid unecessary memory overhead related to storing the signatures
#          of the ACPI tables recognized by the kernel (Ard Biesheuvel).
#     
#        - Add missing newline characters when printing module parameter
#          values in some places (Xiongfeng Wang).
#     
#        - Update the link to the ACPI specifications in some places (Tiezhu
#          Yang).
#     
#        - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.
#          Silva).
#     
#        - Drop redundant variable initialization from the APEI code (Colin
#          Ian King).
#     
#        - Drop uninitialized_var() from the ACPI PAD driver (Jason Yan).
#     
#        - Replace HTTP links with HTTPS ones in the ACPI code (Alexander A.
#          Klimov)"
