ACPICA: Remove acpi_gbl_group_module_level_code and only use acpi_gbl_execute_tables_as_methods instead
acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were used to enable different table load behavior. The different table load behaviors are as follows: A.) acpi_gbl_group_module_level_code enabled the legacy approach where ASL if statements are executed after the namespace object has been loaded. B.) acpi_gbl_execute_tables_as_methods is currently used to enable the table load to be a method invocation. This meaning that ASL If statements are executed in-line rather than deferred until after the ACPI namespace has been populated. This is the correct behavior and option A will be removed in the future. We do not support a table load behavior where these variables are assigned the same value. In otherwords, we only support option A or B and do not need acpi_gbl_group_module_level_code to enable A. From now on, acpi_gbl_execute_tables_as_methods == 0 enables option A and acpi_gbl_execute_tables_as_methods == 1 enables option B. Note: option A is expected to be removed in the future and option B will become the only supported table load behavior. Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Rafael J.
