162 * and locals. The data struct is an array of namespace nodes for
163 * each - this allows RefOf and DeRefOf to work properly for these
164 * special data types.
165 *
166 * NOTES: WalkState fields are initialized to zero by the
167 * ACPI_MEM_CALLOCATE().
168 *
169 * A pseudo-Namespace Node is assigned to each argument and local
170 * so that RefOf() can return a pointer to the Node.
