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. ACPICA BZ 762. http://acpica.org/bugzilla/show_bug.cgi?id=762 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
