[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.
