Message-ID: <4A9391CD.5020804@kernel.org> Date: Tue, 25 Aug 2009 00:25:01 -0700 From: Yinghai Lu <yinghai@...nel.org> To: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de>, "H. Peter Anvin" <hpa@...or.com> CC: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH] x86: use hard_smp_processor_id to get apic id in identify_cpu and leave phys_proc_id to use initial apic id. otherwise, system with apci id lifting will have wrong apicid in /proc/cpuinfo for 2.6.31 ?
