kbuild: deb-pkg: improve the usability of source package Improve the source package support in case the dpkg-buildpackage is directly used to build binary packages. For cross-compiling, you can set CROSS_COMPILE via the environment variable, but it is better to set it automatically - set it to ${DEB_HOST_GNU_TYPE}- if we are cross-compiling but not from the top Makefile. The generated source package may be carried to a different build environment, which may have a different compiler installed. Run olddefconfig first to set new CONFIG options to their default values without prompting. Take KERNELRELEASE and KBUILD_BUILD_VERSION from the version field of debian/changelog in case it is updated afterwards. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

kbuild: deb-pkg: set CROSS_COMPILE only when undefined Commit 3ab18a625ce4 ("kbuild: deb-pkg: improve the usability of source package") set needless CROSS_COMPILE. For example, 'make allnoconfig bindeb-pkg' on a x86_64 system will set CROSS_COMPILE=i686-linux-gnu-, where the biarch compiler 'gcc' should work for building the i386 kernel. $ uname -m x86_64 $ make allnoconfig bindeb-pkg >/dev/null dpkg-architecture: warning: specified GNU system type i686-linux-gnu does not match CC system type x86_64-linux-gnu, try setting a correct CC environment variable dpkg-source --before-build . debian/rules binary scripts/Kconfig.include:39: C compiler 'i686-linux-gnu-gcc' not found make[6]: *** [scripts/kconfig/Makefile:77: olddefconfig] Error 1 make[5]: *** [Makefile:693: olddefconfig] Error 2 make[4]: *** [Makefile:358: __build_one_by_one] Error 2 make[3]: *** [debian/rules:7: build-arch] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2 make[2]: *** [scripts/Makefile.package:127: bindeb-pkg] Error 2 make[1]: *** [Makefile:1657: bindeb-pkg] Error 2 make: *** [Makefile:358: __build_one_by_one] Error 2 Check whether CROSS_COMPILE is defined, instead of whether it is non-empty. If you invoke debian/rules via Kbuild, CROSS_COMPILE is always defined in the top Makefile.

kbuild: deb-pkg: do not take KERNELRELEASE from the source version KERNELRELEASE does not need to match the package version in changelog. Rather, it conventially matches what is called 'ABINAME', which is a part of the binary package names. Both are the same by default, but the former might be overridden by KDEB_PKGVERSION. In this case, the resulting package would not boot because /lib/modules/$(uname -r) does not point the module directory. Partially revert 3ab18a625ce4 ("kbuild: deb-pkg: improve the usability of source package").
