    kernel/reboot.c: add orderly_reboot for graceful reboot · 7a54f46b
    Joel Stanley authored
    The kernel has orderly_poweroff which allows the kernel to initiate a
    graceful shutdown of userspace, by running /sbin/poweroff.  This adds
    orderly_reboot that will cause userspace to shut itself down by calling
    /sbin/reboot.
    
    This will be used for shutdown initiated by a system controller on
    platforms that do not use ACPI.
    
    orderly_reboot() should be used when the system wants to allow userspace
    to gracefully shut itself down.  For cases where the system may imminently
    catch on fire, the existing emergency_restart() provides an immediate
    reboot without involving userspace.
