53  * Global Notes:
54  *
55  * October 2005: The following list terms have been optimized (from the
56  * original ASL grammar in the ACPI specification) to force the immediate
57  * reduction of each list item so that the parse stack use doesn't increase on
58  * each list element and possibly overflow on very large lists (>4000 items).
59  * This dramatically reduces use of the parse stack overall.
