Date: Wed, 2 Jul 2008 18:53:44 -0700 From: Yinghai Lu <yhlu.kernel@...il.com> To: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de>, "H. Peter Anvin" <hpa@...or.com> Cc: LKML <linux-kernel@...r.kernel.org> Subject: [PATCH] x86: move init_cpu_to_node after get_smp_config when acpi=off, cpu_to_apicid is ready after get_smp_config so need to move init_cpu_to_node after it. otherwise, we will get wrong cpu->node mapping. and it will rely on amd_detect_cmp to correct it. but that is too late. setup_per_cpu_data is already called before that. we will get per_cpu_data on wrong node.
