31 * Note! Normally the Linux I/O macros already take care of
32 * byte-swapping the I/O instructions. However, all accesses using
33 * sOutDW aren't really 32-bit accesses, but should be handled in byte
34 * order. Hence the use of the cpu_to_le32() macro to byte-swap
35 * things to no-op the byte swapping done by the big-endian outl()
