[RESEND PATCH 2/2] mn10300/CPU hotplug: Add missing call tonotify_cpu_starting()

From: Srivatsa S. Bhat
Date: Tue May 15 2012 - 15:03:27 EST


The scheduler depends on receiving the CPU_STARTING notification, without
which we end up into a lot of trouble. So add the missing call to
notify_cpu_starting() in the bringup code.
