+ *          _Lxx and _Exx GPE methods
+ *          _Qxx EC methods
+ *          _T_x compiler temporary variables
+ *
+ *      2) Predefined names that never actually exist within the AML code:
+ *          Predefined resource descriptor field names
+ *
+ *      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.
