So use that as # inspiration, odd coding and all. # # Now the calling convention actually makes sense and works for the # intended purpose. # # Reported-and-tested-by: Kyle Zeng <zengyhkyle@gmail.com> # Acked-by: Eric Dumazet <edumazet@google.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /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 bce9332220bd677d83b19d21502776ad555a0e73 # < make -s -j 160 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- allnoconfig # < make -s -j 160 ARCH=s390 O=/kisskb/build/linus_s390-allnoconfig_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/linus_s390-allnoconfig_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/linus_s390-allnoconfig_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/linus_s390-allnoconfig_s390x-gcc11 # Build took: 0:00:53.305305
