From 7fdb5cea9bf288eb6408538fa67f1559f433ab9d Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Thu, 4 Aug 2016 16:42:42 +0800 Subject: ACPICA: Interpreter: Remove temporary code for External() opcode ACPICA commit f2d349f8a11efc0f438ad6903564f3a6755dc6b9 The interpreter should never see this opcode (it is used by disassemblers), so the final implementation is to return an error.
