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/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9819f682e48c6a7055c5d7a6746411dd3969b0e5 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /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] INFO: Uncompressed kernel (size 0xe95cd0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xf00000) Image Name: Linux-5.12.0-g9819f682e48c Created: Mon May 10 07:13:06 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6868668 Bytes = 6707.68 KiB = 6.55 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 # Build took: 0:02:32.159126
