ACPICA commit d115fe2ffdab449d6107d58580c5afd0a81d65fe This change adds the basic low-level infrastructure for the External AML opcode. The interpreter will simply ignore this op, as the op is intended for use by the disassembler only. Note that External() opcode is useful for disassembler, interpreter can simply ignore it and still return exceptions for unknown control methods so the kernel part only includes the grammar definition of External() opcode in order to ignore it but doesn't interpret it.
