Did you convert the output formats of 'initial_apicid' and 'apicid'
from hexadecimal to decimal in your testing? It was really coincidental
that if the output values were '39' in hexadecimal for the CPU '39'
in decimal :-).

I noticed they were represented in hexadecimal format in
arch/x86/kernel/cpu/debugfs.c:

    seq_printf(m, "initial_apicid:      %x\n", c->topo.initial_apicid);
    seq_printf(m, "apicid:              %x\n", c->topo.apicid);

Thanks!
