    [PATCH] Add emergency_restart() · 7c903473
    Eric W. Biederman authored
    When the kernel is working well and we want to restart cleanly
    kernel_restart is the function to use.   But in many instances
    the kernel wants to reboot when thing are expected to be working
    very badly such as from panic or a software watchdog handler.
    
    This patch adds the function emergency_restart() so that
    callers can be clear what semantics they expect when calling
    restart.  emergency_restart() is expected to be callable
    from interrupt context and possibly reliable in even more
    trying circumstances.
    
    This is an initial generic implementation for all architectures.
