+ *
+ * This module validates predefined ACPI objects that appear in the namespace,
+ * at the time they are evaluated (via acpi_evaluate_object). The purpose of this
+ * validation is to detect problems with BIOS-exposed predefined ACPI objects
+ * before the results are returned to the ACPI-related drivers.
+ *
+ * There are several areas that are validated:
+ *
+ * 1) The number of input arguments as defined by the method/object in the
+ * ASL is validated against the ACPI specification.
+ * 2) The type of the return object (if any) is validated against the ACPI
+ * specification.
+ * 3) For returned package objects, the count of package elements is
+ * validated, as well as the type of each package element. Nested
+ * packages are supported.
+ *
+ * For any problems found, a warning message is issued.
