[PATCH] x86_64: Fix numa node topology detection for srat based x86_64 boxes
2.6.14-rc2 does not assign cpus to proper nodeids on our em64t numa boxen. Our boxes use acpi srat for parsing the numa information. srat_detect_node() used phys_proc_id[] to get to the cpu's local apic id, but phys_proc_id[] represents the cpu<->initial_apic_id mapping. The following patch fixes this problem. Now apicid_to_node[] is properly indexed with the local apic id.
