For the moment, yes.

I'm actually working on some other patches that add the kernel metadata
for memory ranges even if they're not backed by physical memory.  But
_that_ is just for testing and I'll just have to modify whatever you do
here in those patches anyway.

It sounds like you're pretty confident that it has no users, so why
don't you just go ahead and axe it on x86 and config it out completely?
 Folks that need it can just hack it back in.
