url:    https://github.com/0day-ci/linux/commits/Jiri-Olsa/kbuild-Unify-options-for-BTF-generation-for-vmlinux-and-modules/20211027-052639
base:   https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master
config: mips-allyesconfig (attached as .config)
compiler: mips-linux-gcc (GCC) 11.2.0

        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # https://github.com/0day-ci/linux/commit/cd9d0571d9b0204fb3c1badf41ca847ba840e40c

        git fetch --no-tags linux-review Jiri-Olsa/kbuild-Unify-options-for-BTF-generation-for-vmlinux-and-modules/20211027-052639
        git checkout cd9d0571d9b0204fb3c1badf41ca847ba840e40c
