Merge branch 'acpi-tables'

Merge updates related to the handling of static (data-only) ACPI tables
for 6.16-rc1:

 - Add __nonstring annotations for unterminated strings in the static
   ACPI tables parsing code (Kees Cook).

 - Add support for parsing the MRRM ACPI table and sysfs files to
   describe memory regions listed in it (Tony Luck, Anil Keshavamurthy).

 - Remove an (explicitly) unused header file include from the VIOT ACPI
   table parser file (Andy Shevchenko).

 - Improve logging around acpi_initialize_tables() (Bartosz Szczepanek).

* acpi-tables:
  ACPI: MRRM: Fix default max memory region
  ACPI: tables: Improve logging around acpi_initialize_tables()
  ACPI: VIOT: Remove (explicitly) unused header
  ACPI: Add documentation for exposing MRRM data
  ACPI: MRRM: Add /sys files to describe memory ranges
  ACPI: MRRM: Minimal parse of ACPI MRRM table
  ACPI: tables: Add __nonstring annotations for unterminated strings
