From 7f0c826a437157d2b19662977e9cf3b472cf24a6 Mon Sep 17 00:00:00 2001 From: Lin Ming Date: Thu, 13 Aug 2009 14:03:15 +0800 Subject: ACPICA: Add support for module-level executable AML code Add limited support for executable AML code that exists outside of any control method. This type of code has been illegal since ACPI 2.0. The code must exist in an If/Else/While block. All AML tables are supported, including tables that are dynamically loaded.
