Exactly. In particular we don't want people to get the wrong idea about
where we are heading, so making it possible to use this code on embedded
systems for me is a reason *not* to take the patch.

People are trying to deploy ACPI-based embedded x86, and most of the 
ACPI/DT integration discussion seems to have been based on the idea that 
this is a worthwhile thing to support. If we're not interested in doing 
so then we should probably make that a whole kernel decision rather than 
a per architecture one.

I agree, thanks for this information.
