commit: ca6cb5447ceca6a87d6b62c9e5d41042c34f7ffa [5640/13335] riscv, bpf: Factor common RISC-V JIT code
config: riscv-randconfig-a001-20200331 (attached as .config)

reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout ca6cb5447ceca6a87d6b62c9e5d41042c34f7ffa
        # save the attached .config to linux build tree
