-/*******************************************************************************
- *
- * FUNCTION: acpi_ps_link_module_code
- *
- * PARAMETERS: parent_op - Parent parser op
- * aml_start - Pointer to the AML
- * aml_length - Length of executable AML
- * owner_id - owner_id of module level code
- *
- * RETURN: None.
- *
- * DESCRIPTION: Wrap the module-level code with a method object and link the
- * object to the global list. Note, the mutex field of the method
- * object is used to link multiple module-level code objects.
- *
- * NOTE: In this legacy option, each block of detected executable AML
- * code that is outside of any control method is wrapped with a temporary
- * control method object and placed on a global list below.
- *
- * This function executes the module-level code for all tables only after
- * all of the tables have been loaded. It is a legacy option and is
- * not compatible with other ACPI implementations. See acpi_ns_load_table.
- *
- * This function will be removed when the legacy option is removed.
- *
