Hi Andrew,
It's probably a bug fix that unveils the link errors.
tree: git://git.cmpxchg.org/linux-mmotm.git master
head: f1560529a066beae1f8bc50a2139b796c01534f1
commit: e79fde04cef13b9356b75883ffa6e2b18a6f7530 [262/281] linux-next-rejects
config: i386-randconfig-n0-201746 (attached as .config)
compiler: gcc-6 (Debian 6.4.0-9) 6.4.0 20171026
reproduce:
git checkout e79fde04cef13b9356b75883ffa6e2b18a6f7530
# save the attached .config to linux build tree
make ARCH=i386
All errors (new ones prefixed by >>):
