This domctl will allow toolstack to read and write some

Can you explain why we would need this on ARM?
What this is meant to say is that the new domctl is not specific to x86
and therefore is available as a common (as opposed to arch-specific)
interface.
I thought you were planning to make this implemented on ARM and was
trying to understanding why :).
If ARM ever needs to access ACPI space from toostack it should be able
to use it (provided that an implementation for that is available in
arch/arm).
Ok. I can't tell whether we would need it in the future. Currently, it
is not necessary.
