tile/CPU hotplug: Add missing call to notify_cpu_starting()
Srivatsa S. Bhat [Thu, 22 Mar 2012 11:29:11 +0000 (16:29 +0530)]
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.
