Hi, Andriy.

I tried your patch and see no regression on Xeon 50xx, 55xx, 54xx.
It also improved CPU detection on Xeon 54xx (as well as original
Junk-uk's patch).

It also improved CPU detection on Xen HVM @ Xeon 55xx @ 3 cores:

FreeBSD/SMP: Multiprocessor System Detected: 3 CPUs
FreeBSD/SMP: 1 package(s) x 3 core(s)
 cpu0 (BSP): APIC ID:  0
 cpu1 (AP): APIC ID:  2
 cpu2 (AP): APIC ID:  4
