* Sane hardware offers swapping of PCI / ISA I / O space accesses in hardware ;
* less sane hardware forces software to fiddle with this . . .
*
* Regardless , if the host bus endianness mismatches that of PCI / ISA , then
* you can ' t have the numerical value of data and byte addresses within
* multibyte quantities both preserved at the same time . Hence two
* variations of functions : non - prefixed ones that preserve the value
* and prefixed ones that preserve byte addresses . The latters are
* typically used for moving raw data between a peripheral and memory ( cf .
* string I / O functions ) , hence the " _ _ mem_ " prefix .
