sh: mark end of BUG() implementation as unreachable
When building the sh architecture, the compiler doesn't realize that BUG() doesn't return, so it will complain about functions using BUG() that are marked with the noreturn attribute: lib/string.c: In function 'fortify_panic': >> lib/string.c:986:1: warning: 'noreturn' function does return } ^ Link: http://lkml.kernel.org/r/20170627192050.GA66784@beast Signed-off-by: Kees Cook <keescook@chromium.org> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Rich Felker <dalias@libc.org> Cc: Daniel Micay <danielmicay@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
