    ACPI, APEI, EINJ, new parameter to control trigger action · ee49089d
    Chen Gong authored
    Some APEI firmware implementation will access injected address
    specified in param1 to trigger the error when injecting memory
    error, which means if one SRAR error is injected, the crash
    always happens because it is executed in kernel context. This
    new parameter can disable trigger action and control is taken
    over by the user. In this way, an SRAR error can happen in user
    context instead of crashing the system. This function is highly
    depended on BIOS implementation so please ensure you know the
    BIOS trigger procedure before you enable this switch.
    
    v2:
      notrigger should be created together with param1/param2
