   module: potential uninitialized return in module_kallsyms_on_each_symbol() (2021-02-10 16:57:04 +0100)

Modules updates for v5.12

Summary of modules changes for the 5.12 merge window:

- 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)
