Hi all We found a warning from objtool: arch/x86/entry/entry_64.o: warning: objtool: .entry.text+0x1d1: unsupported intra-function call and if we enable retpoline in config: arch/x86/entry/entry_64.o: warning: objtool: .entry.text+0x1c1: unsupported intra-function call arch/x86/entry/entry_64.o: warning: objtool: If this is a retpoline, please patch it in with alternatives and annotate it with ANNOTATE_NOSPEC_ALTERNATIVE. I found this issue has been introduced since “x86/speculation: Change FILL_RETURN_BUFFER to work with objtool( commit 8afd1c7da2)”backported in v5.4.217. Comparing with the upstream version(commit 089dd8e53): There is no “ANNOTATE_INTRA_FUNCTION_CALL” in v5.4 for missing dependency patch. When the “ANNOTATE_NOSPEC_ALTERNATIVE” is removed, this issue just occurs. I tried to backport “ANNOTATE_INTRA_FUNCTION_CALL”and its dependency patchs in v5.4, but I met the CFA miss match issue from objtool. So, please help check this issue in v5.4 LTS version.
