commit: ea8daa7b97842aab8507b5b5b1e3226cf2d514a6 kbuild: Add option to turn incompatible pointer check into error
date: 6 months ago
config: cris-artpec_3_defconfig (attached as .config)
compiler: cris-linux-gcc (GCC) 6.2.0
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 ea8daa7b97842aab8507b5b5b1e3226cf2d514a6
# save the attached .config to linux build tree
