Modified files:
sys/i386/i386 identcpu.c
Log:
There may exist two kinds of IBM BlueLightning CPU. One is that 5/2
test does not change undefined flag like Cyrix CPUs. Another is that
5/2 test changes undefined flag like Intel CPUs. Latter one could not
be detected and was recognized 486DX CPU. To solve this,
finishidentcpu() calls identblue() when cpu_vendor is null string
(that is, CPUID instruction is not supported) and cpu == CPU_486.
Tests have been done on IBM BlueLightning CPUs, i486SX and i486DX.
