Subject: [PATCH 6/6] x86: acpi-use-cpu_physical_id (v2)
Date: Fri, 24 Aug 2007 15:27:00 -0700 [thread overview]
Message-ID: <20070824222949.238692000@sgi.com> (raw)
In-Reply-To: 20070824222654.687510000@sgi.com
[-- Attachment #1: acpi-use-cpu_physical_id --]
[-- Type: text/plain, Size: 1396 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.
Signed-off-by: Christoph Lameter <clameter@sgi.com>
Additionally, boot_cpu_id needed to be exported to fix compile errors in
dma code when !CONFIG_SMP.
Signed-off-by: Mike Travis <travis@sgi.com>
