+ * DESCRIPTION: Load ACPI/AML table by executing the entire table as a single

+ *
+ * NOTE: The point of this is to execute any module-level code in-place
+ * as the table is parsed. Some AML code depends on this behavior.
+ *
+ * It is a run-time option at this time, but will eventually become
+ * the default.
+ *
+ * Note: This causes the table to only have a single-pass parse.
+ * However, this is compatible with other ACPI implementations.
