We can fix this with a trick from hpa in the x86 code, we # statically check the type of x and set the type of __gu_val to either # unsigned long or unsigned long long. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 397758385ba96da48a96f82cf3521f994f3a78b3 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_RADIX_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- powernv_defconfig # Added to kconfig CONFIG_PPC_RADIX_MMU=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_RADIX_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig+NO_RADIX_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
