4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Simon Ser <[email protected]> commit ce90aaf5cde4ce057b297bb6c955caf16ef00ee6 upstream. Fix a seg fault which happens when an input file provided to 'objtool orc generate' doesn't have a '.shstrtab' section (for instance, object files produced by clang don't have this section).
