Presumably there are flushes happening via other # paths such as arch_leave_lazy_mmu_mode(), and/or a bit of luck. # # Fix it by reinstating the call to hash__tlb_flush(). # # Fixes: baf1ed24b27d ("powerpc/mm: Remove empty hash__ functions") # Signed-off-by: Michael Ellerman # < /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 37e5bf9657c8af85b91dda79c14eee5b7e0406d7 # < make -s -j 32 ARCH=s390 O=/kisskb/build/powerpc-fixes_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 32 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 32 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig .config:3652:warning: override: reassigning to symbol DEBUG_INFO_BTF # make -s -j 32 ARCH=s390 O=/kisskb/build/powerpc-fixes_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:1061:2: /kisskb/src/arch/s390/kernel/setup.c:526:9: warning: 'memcpy' offset [0, 127] is out of the bounds [0, 0] [-Warray-bounds] 526 | memcpy(abs_lc->cregs_save_area, S390_lowcore.cregs_save_area, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 527 | sizeof(abs_lc->cregs_save_area)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc11 # Build took: 0:04:09.371148
