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-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 b7a2d47af3a0d58527e3a53ab85f597cd495b7ce # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc8540_ads_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_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-next_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x5252f8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x514d40) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.11.0-rc2-gb7a2d47af3a0 Created: Fri Feb 12 04:15:47 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2657699 Bytes = 2595.41 KiB = 2.53 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.11.0-rc2-gb7a2d47af3a0 Created: Fri Feb 12 04:15:47 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2688226 Bytes = 2625.22 KiB = 2.56 MiB Load Address: 00600000 Entry Point: 006002a4 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_powerpc-gcc4.9 # Build took: 0:00:54.919550
