Not quite. sparc64 is the only user which makes any use of the addresses passed to it, but frv does a little assembler with it, and arm26 does a printk - eh? I'd take that to mean that it never gets called there, but I don't see what prevents it, before or now.

Depends really on what DavidH wants there, not clear to me. I suspect Ian can live without his printk!
