bbc81fd432 ARM: CPU hotplug: remove bug checks in platform_cpu_die() 
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.

3c030beabf 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.
