[PATCH v2 0/2] Support clean reboot after hibernate on Arm64

When the hardware signature in the ACPI FACS changes, the OS is supposed
to perform a clean reboot instead of attempting to resume on a changed
platform.

Although these patches have a functional dependency, they could be merged
separately. The second patch just won't *see* a FACS table if the ACPICA
fix isn't present.

v2: Now that the ACPICA patch is merged upstream, note its commit ID

David Woodhouse (2):
      ACPICA: Detect FACS even for hardware reduced platforms
      arm64: acpi: Honour firmware_signature field of FACS, if it exists
