    Linus Torvalds authored
    Pull objtool updates from Ingo Molnar:
     "Most of the changes are cleanups and reorganization to make the
      objtool code more arch-agnostic. This is in preparation for non-x86
      support.
    
      Other changes:
    
       - KASAN fixes
    
       - Handle unreachable trap after call to noreturn functions better
    
       - Ignore unreachable fake jumps
    
       - Misc smaller fixes & cleanups"
