* 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.
