[PATCH 6/6] x86: acpi-use-cpu_physical_id
From: <hidden>
Date: 2007-08-22 18:59:33
Also in:
lkml
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.
