[PATCH 6/6] x86: acpi-use-cpu_physical_id

From: travis
Date: Wed Aug 22 2007 - 14:59:34 EST


This is from an earlier message from Christoph Lameter:

processor_core.c currently tries to determine the apicid by special casing
for IA64 and x86. The desired information is readily available via

cpu_physical_id()

on IA64, i386 and x86_64.
