Josh Poimboeuf 7631376b2d objtool: Fix retpoline detection in asm code ... [ Upstream commit 1f9a1b74942485a0a29e7c4a9a9f2fe8aea17766 ] The JMP_NOSPEC macro branches to __x86_retpoline_*() rather than the __x86_indirect_thunk_*() wrappers used by C code. Detect jumps to __x86_retpoline_*() as retpoline dynamic jumps. Presumably this doesn't trigger a user-visible bug. I only found it when testing vmlinux.o validation.
