  16    This function executes installed reset handlers.
  17    It stores the supplied shutdown action type (SD_ACTION_#?) in the
  18    ln_Type field of each reset interrupt structure. Typically this
  19    information is needed by system reset handlers (EFI, ACPI etc.), but
  20    not by peripheral-device reset handlers (USB HCs, NICs etc.).
  21    For improved safety callbacks are called in a Disable()d state.
  22    This function does not need to Enable().
