Hi,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-3.10.y
head:   ca1199fccf14540e86f6da955333e31d6fec5f3e
commit: a4a4f1cd733fe5b345db4e8cc19bb8868d562a8a [4/144] compiler-gcc: integrate the various compiler-gcc[345].h files
config: i386-randconfig-s1-201625 (attached as .config)
compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430
reproduce:
        git checkout a4a4f1cd733fe5b345db4e8cc19bb8868d562a8a
        # save the attached .config to linux build tree
        make ARCH=i386
