[PATCH 22/22] ARM: SMP: remove smp_mpidr.h
Russell King - ARM Linux

Fri Dec 3 15:26:23 EST 2010
With "ARM: CPU hotplug: remove bug checks in platform_cpu_die()", we
now do not use hard_smp_processor_id(), we no longer need to read the
hardware processor ID. Remove the include providing this function.
