tree:   https://kernel.googlesource.com/pub/scm/linux/kernel/git/davem/net-next.git master
head:   2cc2743d8feec87b0bc0c9c1106136852d97f566
commit: 171a9bae68c72f2d1260c3825203760856e6793b [57/138] staging/octeon: Allow test build on !MIPS
config: mips-allmodconfig (attached as .config)
compiler: mips-linux-gcc (GCC) 7.4.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 171a9bae68c72f2d1260c3825203760856e6793b
        # save the attached .config to linux build tree
        GCC_VERSION=7.4.0 make.cross ARCH=mips
