Linus Torvalds 2baa85d692 ACPI updates for 5.9-rc1
- 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).

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).
