+ *
+ * FUNCTION:    acpi_ut_predefined_bios_error
+ *
+ * PARAMETERS:  module_name     - Caller's module name (for error output)
+ *              line_number     - Caller's line number (for error output)
+ *              pathname        - Full pathname to the node
+ *              node_flags      - From Namespace node for the method/object
+ *              format          - Printf format string + additional args
+ *
+ * RETURN:      None
+ *
+ * DESCRIPTION: BIOS error message for predefined names. Messages
+ *              are only emitted the first time a problem with a particular
+ *              method/object is detected. This prevents a flood of
+ *              messages for methods that are repeatedly evaluated.
