[dann frazier]

BugLink: https://bugs.launchpad.net/bugs/1841490

All clean cherry-picks from upstream. This series is for Eoan. Disco requires
a couple additional patches - I'll submit a Disco series In-Reply-To this
cover letter as well.

Jeremy Linton (4):
  ACPI/PPTT: Modify node flag detection to find last IDENTICAL
  ACPI/PPTT: Add function to return ACPI 6.3 Identical tokens
  arm_pmu: acpi: spe: Add initial MADT/SPE probing
  perf: arm_spe: Enable ACPI/Platform automatic module loading
