/*
* 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.
