I did not comment on that because that's someone elses problem.

Probably - I expect Grant would really like to see some patches along
those lines. As I say, someone elses problem.

But what is _our_ problem is what to do with all the ARCH_NR_GPIOs
that we have now, and stop them increasing. There is a trivial solution
to that which I outlined which can be used until GPIO gets something
along your idea - and which doesn't involve me having to argue with
those who think that the kernel should remain as small as possible.
