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
