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-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 7bcdcd71f432b553a084a88130800196af36e3b1 # < make -s -j 10 ARCH=x86 O=/kisskb/build/kbuild_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 10 ARCH=x86 O=/kisskb/build/kbuild_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 10 ARCH=x86 O=/kisskb/build/kbuild_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 10 ARCH=x86 O=/kisskb/build/kbuild_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: File format not recognized /kisskb/src/lib/bitfield_kunit.c: In function 'test_bitfields_constants': /kisskb/src/lib/bitfield_kunit.c:93:1: warning: the frame size of 7432 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info mm/kfence/kfence_test.o: file not recognized: File format not recognized make[3]: * [/kisskb/src/scripts/Makefile.modfinal:78: mm/kfence/kfence_test.ko] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.modpost:156: __modpost] Error 2 make[1]: * [/kisskb/src/Makefile:1754: modules] Error 2 make: *** [Makefile:215: __sub-make] Error 2 Command 'make -s -j 10 ARCH=x86 O=/kisskb/build/kbuild_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/kbuild_x86-allmodconfig_x86_64-gcc8 # Build took: 0:36:30.864211
