 113  *          _T_x compiler temporary variables

 115  *      2) Predefined names that never actually exist within the AML code:
 116  *          Predefined resource descriptor field names
 117  *
 118  *      3) Predefined names that are implemented within ACPICA:
 119  *          _OSI
 120  *
 121  *      4) Some predefined names that are not documented within the ACPI spec.
 122  *          _WDG, _WED
 123  *
 124  * The main entries in the table each contain the following items:
 125  *
 126  * Name                 - The ACPI reserved name
 127  * param_count          - Number of arguments to the method
 128  * expected_btypes      - Allowed type(s) for the return value.
 129  *                        0 means that no return value is expected.
 130  *
 131  * For methods that return packages, the next entry in the table contains
 132  * information about the expected structure of the package. This information
 133  * is saved here (rather than in a separate table) in order to minimize the
 134  * overall size of the stored data.
