New pahole (version 1.24) generates by default new BTF_KIND_ENUM64 BTF tag, which is not supported by stable kernel. As a result the kernel with CONFIG_DEBUG_INFO_BTF option will fail to compile with following error: BTFIDS vmlinux FAILED: load BTF from vmlinux: Invalid argument New pahole provides --skip_encoding_btf_enum64 option to skip BTF_KIND_ENUM64 generation and produce BTF supported by stable kernel. Adding this option to scripts/pahole-flags.sh. This change does not have equivalent commit in linus tree, because linus tree has support for BTF_KIND_ENUM64 tag, so it does not need to be disabled.
