Whoa! This is not how changes to ACPI work! We have to work out what is needed, then the standard has to be updated, then the upstream acpica project, then these files get synced back across from the 'upstream' acpica project... If you need an ACPI table, we need something for DT too. I don't think a well designed paravirt interface shouldn't need this. Wasn't that the whole point of the KVM "vendor specific" services?! The cover-letter message talks of shared memory, which this doesn't describe. Ideally this stuff would be discovered via SMCCC, or a (readonly?) page of that shared memory. That way its the same regardless of ACPI or DT.
