When the hardware signature in the ACPI FACS changes, the OS is supposed

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

ACPICA: Detect FACS even for hardware reduced platforms
arm64: acpi: Honour firmware_signature field of FACS, if it exists

Rafael, how would you like the handle this series? The arm64 part has
been Acked-by Sudeep, so I'm happy with it.
Thanks, Will.
Similar question for Rafael on the guest side of the PSCI SYSTEM_OFF2
series, in particular
https://lore.kernel.org/kvm/20240319130957.1050637-6-dwmw2@xxxxxxxxxxxxx/#Z31kernel:power:hibernate.c
which sets the entering_platform_hibernation flag around the call to
the standard kernel_power_off() function when invoking it for
HIBERNATION_SHUTDOWN.
In both cases, please feel free to route the patches as it is convenient
and add
Acked-by: Rafael J. Wysocki <rafael@xxxxxxxxxx>
to both of them.
