base:   https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next
config: powerpc-g5_defconfig (attached as .config)
compiler: powerpc64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=powerpc 

Note: the linux-review/Michael-Ellerman/powerpc-Add-security-feature-flags-for-Spectre-Meltdown/20180327-041008 HEAD 95772a19ac473c1aa27b1e5e038791da104b6a06 builds fine.
      It only hurts bisectibility.
