    Subject[PATCH v3 2/7] arm64: Support restart through restart notifier call chain
    Date
    The kernel core now supports a notifier call chain to restart
    the system. Call it if arm_pm_restart is not set.

    Signed-off-by: Guenter Roeck <linux@roeck-us.net>
    ---
    v3: Use wrapper function to execute notifier call chain.
    v2: Only call notifier call chain if arm_pm_restart is not set.
    Do not include linux/watchdog.h.
