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