    This one is for mn10300:

    From: Srivatsa S. Bhat <srivatsa.bhat@linux.vnet.ibm.com>
    Subject: [PATCH] mn10300/CPU hotplug: Add missing call to notify_cpu_starting()

    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.
