    [PATCH] x86-64: Allow to run a program when a machine check event is detected · a98f0dd3
    Andi Kleen authored
    When a machine check event is detected (including a AMD RevF threshold
    overflow event) allow to run a "trigger" program. This allows user space
    to react to such events sooner.
    
    The trigger is configured using a new trigger entry in the
    machinecheck sysfs interface. It is currently shared between
    all CPUs.
    
    I also fixed the AMD threshold handler to run the machine
    check polling code immediately to actually log any events
    that might have caused the threshold interrupt.
    
    Also added some documentation for the mce sysfs interface.
