I revised BlueLightning CPU patch because I found that there are
BlueLightning CPUs which do not change undefined flag by dividing 5 by
2 like Intel CPUs. After my obtaining test reports on *both* IBM
BlueLightning CPUs and old Intel 486 CPUs that do not support cpuid
instruction, I'll commit into current. If the patch has side effect
on non-IBM CPU, of course, I'll discard it.
