Subject: Re: [PATCH] x86_64: store Socket ID in phys_proc_id

Current code store phys_proc_id with init APIC ID, and later will change
to apicid>>bits.

So for the apic id lifted system, for example BSP with apicid 0x10, the
phys_proc_id will be 8.

This patch use initial APIC ID to get Socket ID.

It also removed ht_nodeid calculating, because We already have correct
socket id for sure.
