Ok, glad you got that working.

 What about the ACPI changes? I see that these are needed to get a clean build,
and as I understood it, they are supposed to get merged through the
acpica tree.

Right, that is ok to keep in there, we should fix that by adding a Kconfig
dependency for the driver. It looks like it has a CONFIG_ACPI dependency,
so it is currently limited to x86/arm64/ia64, which all have the short
cmpxchg(),
but in reality this driver can only work on x86 and arm64.
