Currently, kheaders_data.tar.xz contains some build scripts as well as headers. None of them is needed in the header archive. For ARCH=x86, this commit excludes the following from the archive: arch/x86/include/asm/Kbuild arch/x86/include/uapi/asm/Kbuild include/asm-generic/Kbuild include/config/auto.conf include/config/kernel.release include/config/tristate.conf include/uapi/asm-generic/Kbuild include/uapi/Kbuild kernel/gen_kheaders.sh This change is actually motivated for the planned header compile-testing because it will generate more build artifacts, which should not be included in the archive.
