base:   https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next
config: powerpc-defconfig (attached as .config)

        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=powerpc 

Note: the linux-review/Nicholas-Piggin/powerpc-NMI-IPIs/20161109-005049 HEAD ebfcf2d2f068a2e00d385864b5ba9371e15adcef builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
