Linus Torvalds f84a52eef5 - A bunch of improvements, cleanups and fixlets to the SRSO mitigation

machinery and other, general cleanups to the hw mitigations code,
   by Josh Poimboeuf
 
 - Improve the return thunk detection by objtool as it is absolutely
   important that the default return thunk is not used after returns
   have been patched. Future work to detect and report this better is
   pending
 
 - Other misc cleanups and fixes
