RE: Enable apic ext id to use 256 apic id for AMD64

[YhLu]

Please refer s4882 to change the MB that you support.

nodeid = lapicid() & 0xf;

orm with initial apic id
     nodeid = (cpuid_ebx(1) >> 24) & 0xf;

YhLU,

You change the cpu_init_detected(void) to cpu_init_detected(nodeid),
what should I put in the nodeid? You break EVERY K8 mainboard we
have.
