Message-Id: <1193910960937-git-send-email-gcosta@redhat.com> Date: Thu, 1 Nov 2007 06:56:00 -0300 From: Glauber de Oliveira Costa <gcosta@...hat.com> To: linux-kernel@...r.kernel.org Cc: akpm@...ux-foundation.org, glommer@...il.com, tglx@...utronix.de, mingo@...e.hu, Glauber de Oliveira Costa <gcosta@...hat.com> Subject: [PATCH] show right output for cpuinfo in x86_64 smp systems, a regression was introduced a few days after 2.6.23, on its way to 2.6.23. Bisection leads me to commit 92cb7612aee39642d109b8d935ad265e602c0563. The problem is that the output of 'cat /proc/cpuinfo' shows 0 as the id of all cpus of a smp system. As far as I know, this only happens on x86_64 systems. This problem was first noticed by Ravikiran.
