Michal Kubecek	03d7a1053c	objtool: Check that module init/exit function is an indirect call target ... Some out-of-tree modules still do not use module_init() / module_exit() macros and simply create functions with magic names init_module() and cleanup_module() instead. As a result, these functions are not recognized as indirect call targets by objtool and such module fails to load into an IBT enabled kernel. This old way is not even documented any more but it is cleaner to issue a warning than to let the module fail on load without obvious reason.

Josh Poimboeuf	a8e35fece4	objtool: Update documentation ... The objtool documentation is very stack validation centric. Broaden the documentation and describe all the features objtool supports.
