	See drivers/net/pcnet32.c for one example of its use.  There are
no #ifdef's like NetBSD uses.  le16_to_cpu() is a no-op on LE machines, so
one uses it directly like 

short x = le16_to_cpu(dev_flag);

	The macros seem to be included via <asm/bitops.h> which then
include <linux/byteorder/big_endian.h> (for example).
