- * The acpi_operand_object is used to pass AML operands from the dispatcher
- * to the interpreter, and to keep track of the various handlers such as
- * address space handlers and notify handlers. The object is a constant
- * size in order to allow them to be cached and reused.
- *
- * All variants of the acpi_operand_object are defined with the same
- * sequence of field types, with fields that are not used in a particular
- * variant being named "Reserved". This is not strictly necessary, but
- * may in some circumstances simplify understanding if these structures
- * need to be displayed in a debugger having limited (or no) support for
- * union types. It also simplifies some debug code in Dump_table() which
- * dumps multi-level values: fetching Buffer.Pointer suffices to pick up
- * the value or next level for any of several types.
