Linus Torvalds 6cbf0c704d iomap: make the default iomap functions fail softer ... We used to BUG_ON() for a badly mapped IO port, which is certainly correct, but actually made it harder to debug the case where the ATA drivers had incorrectly mapped a nonconnected ATA port. So make badly mapped ports trigger a WARN_ON(), and throw the IO away instead (and return all ones for reads). For things like broken driver initialization - which is the most likely cause anyway - that should mean that the machine comes up and is usable (at least that was the case for the ATA breakage that triggered this patch). It tends to be a whole lot easier to do a "dmesg" on a working machine than to try to capture logs off a dead one.
