1/*
2 * NSC/Cyrix CPU indexed register access. Must be inlined instead of
3 * macros to ensure correct access ordering
4 * Access order is always 0x22 (=offset), 0x23 (=value)
5 *
6 * When using the old macros a line like
7 * setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
8 * gets expanded to:
9 * do {
10 * outb((CX86_CCR2), 0x22);
11 * outb((({
12 * outb((CX86_CCR2), 0x22);
13 * inb(0x23);
14 * }) | 0x88), 0x23);
15 * } while (0);
16 *
17 * which in fact violates the access order (= 0x22, 0x22, 0x23, 0x23).
