527 | Use unordered stores to access IO memory mappings in device drivers. | ||
528 | Still very experimental. When a driver works on IA64/ppc64/pa-risc it should | ||
529 | work with this option, but it makes the drivers behave differently | ||
530 | from i386. Requires that the driver writer used memory barriers | ||
531 | properly. | ||
