commit: 167c8216358d558928a38ebbc64d0f6ee239ac3c [3/6] ppc: signal_32 - switch to {COMPAT_,}SYSCALL_DEFINE
config: powerpc-walnut_defconfig (attached as .config)
compiler: powerpc-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
        git checkout 167c8216358d558928a38ebbc64d0f6ee239ac3c
        # save the attached .config to linux build tree
        make.cross ARCH=powerpc
