ARM: CPU hotplug: remove bug checks in platform_cpu_die() 2010-12-20T15:09:10+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-11-30T11:12:30+00:00 bbc81fd4327f9ed4480b05981e38acd48b1d184a platform_cpu_die() is entered from the CPU's own idle thread, which can not be migrated to other CPUs. 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>
