Fix it by enforcing the load update through the hierarchy # for unthrottled run queue instances. # # - A documentation fix fot the 'sched_verbose' command line option" # # * tag 'sched-urgent-2021-05-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # sched/fair: Fix unfairness caused by missing load decay # sched: Fix out-of-bound access in uclamp # psi: Fix psi state corruption when schedule() races with cgroup move # sched,doc: sched_debug_verbose cmdline should be sched_verbose # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 9819f682e48c6a7055c5d7a6746411dd3969b0e5 # < make -s -j 120 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- multi_v7_defconfig # < make -s -j 120 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- help # make -s -j 120 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- olddefconfig # make -s -j 120 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- In file included from /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/tm.h:23, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:15, from /kisskb/src/scripts/gcc-plugins/arm_ssp_per_task_plugin.c:3: /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/config/elfos.h:102:21: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] fprintf ((FILE), "%s"HOST_WIDE_INT_PRINT_UNSIGNED"\n",\ ^ /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/config/elfos.h:170:24: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] fprintf ((FILE), ","HOST_WIDE_INT_PRINT_UNSIGNED",%u\n", \ ^ In file included from /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/tm.h:44, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:15, from /kisskb/src/scripts/gcc-plugins/arm_ssp_per_task_plugin.c:3: /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/defaults.h:126:24: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] fprintf ((FILE), ","HOST_WIDE_INT_PRINT_UNSIGNED",%u\n", \ ^ cc1plus: warning: unrecognized command line option '-Wno-format-diag' /kisskb/src/arch/arm/crypto/ghash-ce-glue.c: In function 'ghash_do_update': /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:67:44: warning: passing argument 4 of 'pmull_ghash_update_p64' from incompatible pointer type pmull_ghash_update_p64(blocks, dg, src, key->h, head); ^ /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:45:17: note: expected 'const u64 (*)[2]' but argument is of type 'u64 (*)[2]' asmlinkage void pmull_ghash_update_p64(int blocks, u64 dg[], const char *src, ^ /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:69:43: warning: passing argument 4 of 'pmull_ghash_update_p8' from incompatible pointer type pmull_ghash_update_p8(blocks, dg, src, key->h, head); ^ /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:48:17: note: expected 'const u64 (*)[2]' but argument is of type 'u64 (*)[2]' asmlinkage void pmull_ghash_update_p8(int blocks, u64 dg[], const char *src, ^ /kisskb/src/net/sched/sch_frag.c: In function 'sch_fragment': /kisskb/src/net/sched/sch_frag.c:93:10: warning: missing braces around initializer [-Wmissing-braces] struct rtable sch_frag_rt = { 0 }; ^ /kisskb/src/net/sched/sch_frag.c:93:10: warning: (near initialization for 'sch_frag_rt.dst') [-Wmissing-braces] /kisskb/src/drivers/firmware/qcom_scm-legacy.c: In function 'scm_legacy_call': /kisskb/src/drivers/firmware/qcom_scm-legacy.c:139:9: warning: missing braces around initializer [-Wmissing-braces] struct arm_smccc_args smc = {0}; ^ /kisskb/src/drivers/firmware/qcom_scm-legacy.c:139:9: warning: (near initialization for 'smc.args') [-Wmissing-braces] /kisskb/src/drivers/firmware/qcom_scm-smc.c: In function '__scm_smc_call': /kisskb/src/drivers/firmware/qcom_scm-smc.c:95:9: warning: missing braces around initializer [-Wmissing-braces] struct arm_smccc_args smc = {0}; ^ /kisskb/src/drivers/firmware/qcom_scm-smc.c:95:9: warning: (near initialization for 'smc.args') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 # Build took: 0:02:06.974841
