Message-ID: <20060803183224.GA10797@redhat.com> Mail-Followup-To: Dave Jones , Linux Kernel Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.2.2i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1099 Lines: 27 We have a test that looks for invalid pairings of certain athlon/durons that weren't designed for SMP, and taint accordingly (with 'S') if we find such a configuration. However, this test shouldn't fire if there's only a single CPU present. It's perfectly valid for an SMP kernel to boot on UP hardware for example.
