It looks like this was applied on top of 6.2-rc3 if I am reading your logs right but your mainline testing is recent, 6.2-rc5. I think the errors you are seeing here are just existing mainline regressions that were later fixed. > Following build warnings and errors reported. > > sh: > gcc-11-defconfig — FAIL > gcc-11-shx3_defconfig — FAIL > https://qa-reports.linaro.org/~anders.roxell/linux-mainline-patches/build/https___lore_kernel_org_llvm_20221228-drop-qunused-arguments-v2-1-9adbddd20d86_kernel_org/testrun/14221835/suite/build/tests/ > > mainline getting passed. > https://qa-reports.linaro.org/lkft/linux-mainline-master/build/v6.2-rc5/testrun/14298156/suite/build/test/gcc-11-defconfig/history/ > https://qa-reports.linaro.org/lkft/linux-mainline-master/build/v6.2-rc5/testrun/14298156/suite/build/test/gcc-11-shx3_defconfig/history/ > > Build error: > In function 'follow_pmd_mask', > inlined from 'follow_pud_mask' at /builds/linux/mm/gup.c:735:9, > inlined from 'follow_p4d_mask' at /builds/linux/mm/gup.c:752:9, > inlined from 'follow_page_mask' at /builds/linux/mm/gup.c:809:9: > /builds/linux/include/linux/compiler_types.h:358:45: error: call to > '__compiletime_assert_263' declared with attribute error: Unsupported > access size for {READ,WRITE}_ONCE(). > 358 | _compiletime_assert(condition, msg, > __compiletime_assert_, __COUNTER__) I think this was fixed with mainline commit 526970be53d5 ("sh/mm: Fix pmd_t for real"), released in 6.2-rc4. You can see a previous build failing in the same manner: https://qa-reports.linaro.org/lkft/linux-mainline-master/build/v6.2-rc3-9-g5a41237ad1d4/testrun/14056384/suite/build/tests/ > s390: > clang-15-defconfig — FAIL > https://qa-reports.linaro.org/~anders.roxell/linux-mainline-patches/build/https___lore_kernel_org_llvm_20221228-drop-qunused-arguments-v2-1-9adbddd20d86_kernel_org/testrun/14221913/suite/build/tests/ > > mainline getting passed. > https://qa-reports.linaro.org/lkft/linux-mainline-master/build/v6.2-rc5/testrun/14300495/suite/build/test/clang-15-defconfig/history/ > > Build error: > make --silent --keep-going --jobs=8 > O=/home/tuxbuild/.cache/tuxmake/builds/1/build LLVM_IAS=0 ARCH=s390 > CROSS_COMPILE=s390x-linux-gnu- 'HOSTCC=sccache clang' 'CC=sccache > clang' > `.exit.text' referenced in section `__jump_table' of fs/fuse/inode.o: > defined in discarded section `.exit.text' of fs/fuse/inode.o > `.exit.text' referenced in section `__jump_table' of fs/fuse/inode.o: > defined in discarded section `.exit.text' of fs/fuse/inode.o > `.exit.text' referenced in section `__bug_table' of crypto/algboss.o: > defined in discarded section `.exit.text' of crypto/algboss.o > `.exit.text' referenced in section `__bug_table' of drivers/scsi/sd.o: > defined in discarded section `.exit.text' of drivers/scsi/sd.o > `.exit.text' referenced in section `__jump_table' of drivers/md/md.o: > defined in discarded section `.exit.text' of drivers/md/md.o > `.exit.text' referenced in section `__jump_table' of drivers/md/md.o: > defined in discarded section `.exit.text' of drivers/md/md.o > `.exit.text' referenced in section `.altinstructions' of > drivers/md/md.o: defined in discarded section `.exit.text' of > drivers/md/md.o > `.exit.text' referenced in section `.altinstructions' of > drivers/md/md.o: defined in discarded section `.exit.text' of > drivers/md/md.o > `.exit.text' referenced in section `.altinstructions' of > net/iucv/iucv.o: defined in discarded section `.exit.text' of > net/iucv/iucv.o > `.exit.text' referenced in section `__bug_table' of > drivers/s390/cio/qdio_thinint.o: defined in discarded section > `.exit.text' of drivers/s390/cio/qdio_thinint.o > `.exit.text' referenced in section `__bug_table' of > drivers/s390/net/qeth_l3_main.o: defined in discarded section > `.exit.text' of drivers/s390/net/qeth_l3_main.o > `.exit.text' referenced in section `__bug_table' of > drivers/s390/net/qeth_l3_main.o: defined in discarded section > `.exit.text' of drivers/s390/net/qeth_l3_main.o > s390x-linux-gnu-ld: BFD (GNU Binutils for Debian) 2.35.2 assertion > fail ../../bfd/elf64-s390.c:3349 > make[2]: *** [/builds/linux/scripts/Makefile.vmlinux:34: vmlinux] Error 1 This should be fixed with mainline commit a494398bde27 ("s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36"), released in 6.2-rc4 as well. Same as before, visible in mainline at one point without this series: https://qa-reports.linaro.org/lkft/linux-mainline-master/build/v6.2-rc3-9-g5a41237ad1d4/testrun/14057142/suite/build/tests/ > But, > Build and boot pass on arm64, arm, x86_64 and i386. > Build test performed for mips, parisc, riscv, s390, sh, sparc and > powerpc (known build errors for maple_defconfig and cell_defconfig), Good to hear! Please consider retesting this series on top of 6.2-rc5 or testing the current kbuild tree, which has this series applied in it: https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git/log/?h=for-next Cheers, Nathan
