The latter is used when # CONFIG_RETPOLINE is selected, and this will fail to build with # a gcc which has -fcf-protection=branch enabled by default. Adding # -fcf-protection=none when building with retpoline enabled # prevents such build failures. # # Signed-off-by: Seth Forshee <seth.forshee@canonical.com> # Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9b2802e2b3b9222cc7703b0a38ae340af79de521 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/kbuild_powernv_defconfig+NO_PERF_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_PERF_EVENTS=n # yes \n \| make -s -j 80 ARCH=powerpc O=/kisskb/build/kbuild_powernv_defconfig+NO_PERF_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=powerpc O=/kisskb/build/kbuild_powernv_defconfig+NO_PERF_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1651:6: note: 'oldval' was declared here int oldval, ret; ^ WARNING: vmlinux.o(.text+0x2fd0): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel() The function start_here_common() references the function __init start_kernel().
