RE: 256 apic id for amd64

arch/x86_64/kernel/setup.c

static void __init detect_ht(struct cpuinfo_x86 *c)

                phys_proc_id[cpu] = phys_pkg_id(index_msb);

--->
			  Phy_proc_id[cpu] = cpu_to_node[cpu];
Or
   	      // that is initial apicid
          phys_proc_id[cpu] = c->x86_apicid >> hweight32(c->x86_num_cores -
1);
