Message-Id: <20070720153252.C0AC514E79@wotan.suse.de> Date: Fri, 20 Jul 2007 17:32:52 +0200 (CEST) From: Andi Kleen <ak@...e.de> To: mathieu.desnoyers@...ymtl.ca, andi@...stfloor.org, patches@...-64.org, linux-kernel@...r.kernel.org Subject: [PATCH] [8/11] x86_64: x86_64 - Use non locked version for local_cmpxchg() From: Mathieu Desnoyers <mathieu.desnoyers@...ymtl.ca> x86_64 - Use non locked version for local_cmpxchg() local_cmpxchg() should not use any LOCK prefix. This change probably got lost in the move to cmpxchg.h.
