There's no reason for it to be there.

Yes, they are, but for a reason.  Having them in there makes it easier to
rework and clean up the core.

So maybe the GTDT code should be there too?

It is a problem.  drivers/acpi/ is not the right place for arch-specific code.

The consolidation of what exactly?

In particular, how does the GTDT code in drivers/acpi/ help to consolidate
anything?

Thanks,
