As suggested by Chris Riedl, turning ftrace on and off does a # large amount of code patching so is a convenient way to see this kind # of fault. # # Add a selftest to try and trigger this kind of a spurious fault. It # tests for 30 seconds which is usually long enough for the issue to # show up. # # Signed-off-by: Jordan Niethe <jniethe5@gmail.com> # [mpe: Rename it to better reflect what it does, rather than the symptom] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210208032957.1232102-2-jniethe5@gmail.com # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 b7a2d47af3a0d58527e3a53ab85f597cd495b7ce # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x4FCCC028 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:6189:warning: override: reassigning to symbol STANDALONE .config:6193:warning: override: reassigning to symbol PPC64 .config:6194:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:6196:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:6198:warning: override: reassigning to symbol GCC_PLUGINS .config:6201:warning: override: reassigning to symbol UBSAN # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/tty/serial/8250/8250_of.c: In function 'of_platform_serial_probe': /kisskb/src/drivers/tty/serial/8250/8250_of.c:244:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=] 244 \| } \| ^ Completed OK # rm -rf /kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 # Build took: 0:04:58.828847
