[Cbe-oss-dev] [PATCH] Implement check_legacy_ioport() on PS3

[David Woodhouse]

It doesn't like it when we poke at legacy I/O ports like the i8042. We
should probably change the _default_ to return -ENODEV, and let any
strange platform which wants to allow unfettered access provide its own
function for that.
