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)
