 116  *          _T_x compiler temporary variables

 119  *          Predefined resource descriptor field names
 120  *
 121  *      3) Predefined names that are implemented within ACPICA:
 122  *          _OSI

 124  *      4) Some predefined names that are not documented within the ACPI spec.
 125  *          _WDG, _WED

 127  * The main entries in the table each contain the following items:
 128  *
 129  * Name                 - The ACPI reserved name
 130  * param_count          - Number of arguments to the method
 131  * expected_btypes      - Allowed type(s) for the return value.
 132  *                        0 means that no return value is expected.
 133  *
 134  * For methods that return packages, the next entry in the table contains
 135  * information about the expected structure of the package. This information
 136  * is saved here (rather than in a separate table) in order to minimize the
 137  * overall size of the stored data.
