Subject: [PATCH 6/6] x86: acpi-use-cpu_physical_id
Date: Wed, 22 Aug 2007 10:21:07 -0700	[thread overview]
Message-ID: <20070822172124.217932000@sgi.com> (raw)
In-Reply-To: <20070822172101.138513000@sgi.com>

[-- Attachment #1: acpi-use-cpu_physical_id --]
[-- Type: text/plain, Size: 1281 bytes --]

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.
