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 # Signed-off-by: Valentin Schneider # Tested-by: Guenter Roeck # Tested-by: Bharata B Rao # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20210707183831.2106509-1-valentin.schneider@arm.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 2c669ef6979c370f98d4b876e54f19613c81e075 # < make -s -j 10 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 10 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 10 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 10 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-objdump: mm/kfence/kfence_test.o: File format not recognized /kisskb/src/lib/test_scanf.c: In function 'numbers_list_field_width_val_width': /kisskb/src/lib/test_scanf.c:530:1: warning: the frame size of 2480 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/test_scanf.c: In function 'numbers_list_field_width_typemax': /kisskb/src/lib/test_scanf.c:488:1: warning: the frame size of 2952 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/test_scanf.c: In function 'numbers_list': /kisskb/src/lib/test_scanf.c:437:1: warning: the frame size of 2480 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: mm/kfence/kfence_test.o: unable to initialize decompress status for section .debug_info mm/kfence/kfence_test.o: file not recognized: File format not recognized make[3]: *** [/kisskb/src/scripts/Makefile.modfinal:78: mm/kfence/kfence_test.ko] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.modpost:156: __modpost] Error 2 make[1]: *** [/kisskb/src/Makefile:1762: modules] Error 2 make: *** [Makefile:215: __sub-make] Error 2 Command 'make -s -j 10 ARCH=x86 O=/kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_x86-allmodconfig_x86_64-gcc8 # Build took: 0:36:59.369912
