SubjectRe: A simple question about readw, readw and the like
   Date: Thu, 27 Jul 2000 15:12:54 +0200
From: Jamie Lokier <lk@tantalophile.demon.co.uk>

Has anyone considered offsetting the ioremap() return address and
subtracting that offset in readl() et al., to catch bogus drivers
that dereference directly?

I'd guess most drivers are tested only on x86 -- this is one way to
check that they're getting at least one portability issue right.

It would certainly be a good way to spot bugs of this nature, sure.
