    [IA64] Fix kernel hangup in kdump on INIT · 2010d7fe

    Fix the problem that kdump on INIT hung up if kdump kernel image is
    not configured.
    
    The kdump_init_notifier() on monarch CPU stops its operation at
    DIE_INIT_MONARCH_LEAVE time if the kdump kernel image is not
    configured. On the other hand, kdump_init_notifier() on non-monarch
    CPUs get into spin because they don't know the fact the monarch stops
    its operation. This is the cause of this problem. To fix this problem,
    we need to check the kdump kernel image at the top of the
    kdump_init_notifier() function.
