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/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9324130f65f68433372472702ee12969340ce1c3 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_powerpc-allnoconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- allnoconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_powerpc-allnoconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_powerpc-allnoconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_powerpc-allnoconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1236:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ Completed OK # rm -rf /kisskb/build/kbuild_powerpc-allnoconfig_powerpc-gcc4.9 # Build took: 0:00:21.745895
