Seems kind of sad to fail the fault due to a bad block when we were

Agreed - but how do we do this? clear_pmem needs to be able to clear an
arbitrary number of bytes, but to go through the driver, we'd need to
send down a bio? If only the driver had an rw_bytes like interface that
could be used by anyone... :)
