113 * _T_x compiler temporary variables
115 * 2) Predefined names that never actually exist within the AML code:

121 * 4) Some predefined names that are not documented within the ACPI spec.
124 * The main entries in the table each contain the following items:
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.

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
