- fix a bug that corrupts the code by mistakenly rewriting
conditional jumps
- fix another bug generating an incorrect ELF symbol table
during retpoline rewriting"
* tag 'objtool-urgent-2021-06-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
objtool: Only rewrite unconditional retpoline thunk calls
