Therefore, remove hidden fallback, instead # offer user the possibility to say he wants to use toolchain default. # # Reported-by: Pali Rohár # Signed-off-by: Christophe Leroy # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/3fd60c2d8a28668a42b766b18362a526ef47e757.1670420281.git.christophe.leroy@csgroup.eu # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 f2636eaac7dee1d7d096cc115ff4f5111b0c508c # < make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig # < make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- In function 'setup_lowcore_dat_on', inlined from 'setup_arch' at /kisskb/src/arch/s390/kernel/setup.c:1059:2: /kisskb/src/arch/s390/kernel/setup.c:524:9: warning: 'memcpy' offset [0, 127] is out of the bounds [0, 0] [-Warray-bounds] 524 | memcpy(abs_lc->cregs_save_area, S390_lowcore.cregs_save_area, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 525 | sizeof(abs_lc->cregs_save_area)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-next_s390-defconfig_s390x-gcc11 # Build took: 0:02:50.946808
