Moreover, the 'cpu' argument comes from the thread info, which will always be the 'current' CPU. So remove this useless bug check. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

ARM: CPU hotplug: move cpu_killed completion to core code 2010-12-20T15:09:10+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-11-30T11:07:35+00:00 3c030beabf937b1d3b4ecaedfd1fb2f1e2aa0c70 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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
