    Subject[PATCH 12/23] Update sysrq-B to use emergency_restart()

    sysrq calls into the reboot path from an interrupt handler
    we can either push the code do into process context and
    call kernel_restart and get a clean reboot or we can simply
    reboot the machine, and increase our chances of actually
    rebooting. emergency_reboot() seems like the closest match
    to what we have previously done, and what we want.
