/*
* NSC/Cyrix CPU indexed register access. Must be inlined instead of
* macros to ensure correct access ordering
* Access order is always 0x22 (=offset), 0x23 (=value)
*
* When using the old macros a line like
* setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
* gets expanded to:
* do {
* outb((CX86_CCR2), 0x22);
* outb((({
* outb((CX86_CCR2), 0x22);
* inb(0x23);
* }) | 0x88), 0x23);
* } while (0);
*
* which in fact violates the access order (= 0x22, 0x22, 0x23, 0x23).
