Note that this was superfluous # before said commit, as back then the hotplug machinery would invoke # init_idle() via idle_thread_get(), which would have already reset the # CPU's idle task's preempt_count to PREEMPT_ENABLED. # # Get rid of this preempt_count write. # # Fixes: f1a0a376ca0c ("sched/core: Initialize the idle task with preemption disabled") # Reported-by: Bharata B Rao <bharata@linux.ibm.com> # Signed-off-by: Valentin Schneider <valentin.schneider@arm.com> # Tested-by: Guenter Roeck <linux@roeck-us.net> # Tested-by: Bharata B Rao <bharata@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210707183831.2106509-1-valentin.schneider@arm.com # < /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 2c669ef6979c370f98d4b876e54f19613c81e075 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # Added to kconfig CONFIG_CRASH_DUMP=y # Added to kconfig CONFIG_FA_DUMP=y # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4130:warning: override: reassigning to symbol CRASH_DUMP .config:4131:warning: override: reassigning to symbol FA_DUMP # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_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] /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c: In function 'cxgb4_write_partial_sgl': /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c:910:9: warning: missing braces around initializer [-Wmissing-braces] struct ulptx_sge_pair buf[MAX_SKB_FRAGS / 2 + 1] = {0}, *to; ^ /kisskb/src/drivers/net/ethernet/chelsio/cxgb4/sge.c:910:9: warning: (near initialization for 'buf[0]') [-Wmissing-braces] /kisskb/src/fs/btrfs/tree-checker.c: In function 'check_root_item': /kisskb/src/fs/btrfs/tree-checker.c:1071:9: warning: missing braces around initializer [-Wmissing-braces] struct btrfs_root_item ri = { 0 }; ^ /kisskb/src/fs/btrfs/tree-checker.c:1071:9: warning: (near initialization for 'ri.inode') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/powerpc-fixes_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 # Build took: 0:04:06.614247
