config: powerpc-allyesconfig (attached as .config)
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 5eeb50de42fd3251845d03c556db012267c72b3f
# save the attached .config to linux build tree
