-Subject: [PATCH 077/103] objtool: Fix retpoline support for pre-ORC objtool
-
-Objtool 1.0 (pre-ORC) produces the following warning when it encounters
-a retpoline:
-
-  arch/x86/crypto/camellia-aesni-avx2-asm_64.o: warning: objtool: .altinstr_replacement+0xf: return instruction outside of a callable function
-
-That warning is meant to catch GCC bugs and missing ENTRY/ENDPROC
-annotations, neither of which are applicable to alternatives.  Silence
-the warning for alternative instructions, just like objtool 2.0 already
-does.
