    Pull module updates from Jessica Yu:
    
     - Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These
       export types were introduced between 2006 - 2008. All the of the
       unused symbols have been long removed and gpl future symbols were
       converted to gpl quite a long time ago, and I don't believe these
       export types have been used ever since. So, I think it should be safe
       to retire those export types now (Christoph Hellwig)
    
     - Refactor and clean up some aged code cruft in the module loader
       (Christoph Hellwig)
    
     - Build {,module_}kallsyms_on_each_symbol only when livepatching is
       enabled, as it is the only caller (Christoph Hellwig)
    
     - Unexport find_module() and module_mutex and fix the last module
       callers to not rely on these anymore. Make module_mutex internal to
       the module loader (Christoph Hellwig)
    
     - Harden ELF checks on module load and validate ELF structures before
       checking the module signature (Frank van der Linden)
    
     - Fix undefined symbol warning for clang (Fangrui Song)
    
     - Fix smatch warning (Dan Carpenter)
