Hi Sasha,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-3.14.y
head: 43ef7e3ec8016449b3b0afdeaee89053687d1680
commit: 017ff97daa4a7892181a4dd315c657108419da0c [1941/4884] kernel: add support for gcc 5
config: mips-allnoconfig (attached as .config)
compiler: mips-linux-gnu-gcc (Debian 5.4.0-6) 5.4.0 20160609
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 017ff97daa4a7892181a4dd315c657108419da0c
# save the attached .config to linux build tree
