commit: 171a9bae68c72f2d1260c3825203760856e6793b staging/octeon: Allow test build on !MIPS
date: 10 weeks ago
config: mips-allyesconfig (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
