From 2b2612272c77288b2bd53d5831df737cd669cd93 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Mon, 20 Mar 2006 18:37:15 -0600 Subject: [PATCH] [PATCH] powerpc numa: Consolidate assignment of cpus to nodes We can plug the boot cpu into its node independently of whether numa topology is detected. And numa_setup_cpu does the right thing for all cases now, so remove special-casing for non-numa from the cpu hotplug callback.
