The patch titled

------------------------------------------------------
From: Kees Cook <keescook@xxxxxxxxxxxx>
Subject: 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
}
