 *
 *      3) Predefined names that are implemented within ACPICA:
 *          _OSI
 *
 *      4) Some predefined names that are not documented within the ACPI spec.
 *          _WDG, _WED
 *
 * The main entries in the table each contain the following items:
 *
 * name                 - The ACPI reserved name
 * param_count          - Number of arguments to the method
 * expected_btypes      - Allowed type(s) for the return value.
 *                        0 means that no return value is expected.
 *
 * For methods that return packages, the next entry in the table contains
 * information about the expected structure of the package. This information
 * is saved here (rather than in a separate table) in order to minimize the
 * overall size of the stored data.
 *
 * Note: The additional braces are intended to promote portability.
