I thought about that, but then I'd have to edit *every* architecture,
and might need acks from all the maintainers.

I was looking for something that was a total no-op on most architectures.

But if this is preferred, it's not technically difficult at all.

If asm-generic were in the <asm/*.h> search path, it would magically
Just Work, but leftover files from a broken checkout would be a big
potential problem.
