I doubt it is correct to force it on all arches.
They already are volatile; the issue is adding "const".
All io(read|write)* pointers are volatile, IIRC.
No, none are volatile, hence my comment.
[jgarzik@pretzel linux-2.6]$ grep volatile lib/iomap.c include/asm-generic/iomap.h

Maybe you were thinking about writel() and friends, whose implementation
(not prototype!) includes use of volatile.
