From 3c030beabf937b1d3b4ecaedfd1fb2f1e2aa0c70 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 30 Nov 2010 11:07:35 +0000 Subject: ARM: CPU hotplug: move cpu_killed completion to core code We always need to wait for the dying CPU to reach a safe state before taking it down, irrespective of the requirements of the platform. Move the completion code into the ARM SMP hotplug code rather than having each platform re-implement this.
