Hi Darrick,
[auto build test WARNING on v4.3-rc4 -- if it's inappropriate base, please ignore]
config: sh-titan_defconfig (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
# save the attached .config to linux build tree
make.cross ARCH=sh
Note: it may well be a FALSE warning. FWIW you are at least aware of it now.
