ACPICA: acpihelp: Add UUID support, restructure some existing files.
This adds a -u option to acpi_help to display all known ACPI UUIDs. Some existing files in the core code have been restructured. Three new files. [zetalog: changing drivers/acpi/acpica/Makefile accordingly] Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.
