So extend the alignment to 64 bytes # to cover more similar cases. # # [1].https://lore.kernel.org/lkml/20210427090013.GG32408@xsang-OptiPlex-9020/ # [2].https://lore.kernel.org/lkml/20210420030837.GB31773@xsang-OptiPlex-9020/ # Signed-off-by: Feng Tang <feng.tang@intel.com> # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 7bcdcd71f432b553a084a88130800196af36e3b1 # < make -s -j 24 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig arch/arm64/configs/defconfig:1018:warning: override: reassigning to symbol MTK_PMIC_WRAP # < make -s -j 24 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 24 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 24 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- /kisskb/src/arch/arm64/Makefile:25: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum /kisskb/src/arch/arm64/Makefile:33: LSE atomics not supported by binutils Completed OK # rm -rf /kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 # Build took: 0:07:01.698060
