124  *              _T_x compiler temporary variables

128  *
129  *      3) Predefined names that are implemented within ACPICA:
130  *              _OSI
131  *
132  *      4) Some predefined names that are not documented within the ACPI spec.
133  *              _WDG, _WED

136  *
137  * Name                 - The ACPI reserved name
138  * ParamCount           - Number of arguments to the method
139  * ExpectedBtypes       - Allowed type(s) for the return value.
140  *                        0 means that no return value is expected.
141  *
142  * For methods that return packages, the next entry in the table contains
143  * information about the expected structure of the package. This information
144  * is saved here (rather than in a separate table) in order to minimize the
145  * overall size of the stored data.
