Mapping # kernel memory is used when code patching with Strict RWX enabled. 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> # 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 ea721ec55c8a4a166373978b9c8ce77374d684d6 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_warp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/warp_defconfig # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_warp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_warp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_warp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1517:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/zstd/compress.c: In function 'ZSTD_compressBlock_doubleFast': /kisskb/src/lib/zstd/compress.c:1393:1: warning: the frame size of 1584 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ INFO: Uncompressed kernel (size 0x6ce16c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.11.0-rc2-pika+ Created: Thu Feb 11 03:33:34 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3521710 Bytes = 3439.17 KiB = 3.36 MiB Load Address: 00700000 Entry Point: 00701498 Completed OK # rm -rf /kisskb/build/powerpc-next_44x_warp_defconfig_powerpc-gcc4.9 # Build took: 0:00:43.753373
