From a94e88cdd8057fe8ea84bbb6d9a89a823c7bc49b Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Fri, 4 Apr 2014 12:39:11 +0800 Subject: ACPICA: Tables: Avoid SSDT installation with acpi_gbl_disable_ssdt_table_load. It is reported that when acpi_gbl_disable_ssdt_table_load is specified, user still can see it installed into /sys/firmware/acpi/tables on Linux boxes. This is because the option only stops table "loading", but doesn't stop table "installing", thus it is still in the acpi_gbl_root_table_list. With previous cleanups, it is possible to prevent SSDT installations to make it not such confusing. The global variable is also renamed. Lv Zheng.

OSPMs like Linux trend to include all header files but leave empty stub macros for a feature that is not configured during build. This patch cleans up global variables that are defined in utglobal.c using ACPI_INIT_GLOBAL mechanism. In Linux, such global variables are used by the subsystems external to ACPICA. This patch also cleans up global variables that are defined in utglobal.c using ACPI_GLOBAL mechanism. In Linux, such global variables are not used or should not be used by the subsystems external to ACPICA. External global variables can be redefined by OSPMs using ACPI_INIT_GLOBAL/ACPI_GLOBAL macros. Thus the ACPI_GLOBAL/ACPI_INIT_GLOBAL mechanisms can be used by OSPM to implement stubs for such external globals. This patch doesn't include code for Linux to use this new mechanism, thus no functional changes. Lv Zheng. Signed-off-by: Lv Zheng Signed-off-by: Bob Moore Signed-off-by: Rafael J.

This is the linuxize result of the following commit: Subject: ACPICA: Improve handling of exception code blocks. Split exception codes into three distinct blocks; for the main ASL compiler, Table compiler, and the preprocessor. This allows easy addition of new codes into each block without disturbing the others. Adds one new file, aslmessages.c The iASL changes are not in this patch as iASL currently is not shipped in the kernel. Signed-off-by: Bob Moore Signed-off-by: Lv Zheng Signed-off-by: Rafael J.
