Robert Shteynfeld has reported a boot # failure. The boot log was not captured but his memory layout is as # follows: # # Early memory node ranges # node 1: [mem 0x0000000000001000-0x0000000000090fff] # node 1: [mem 0x0000000000100000-0x00000000dbdf8fff] # node 1: [mem 0x0000000100000000-0x0000001423ffffff] # node 0: [mem 0x0000001424000000-0x0000002023ffffff] # # This means that node0 starts in the middle of a memory section which is # also in node1. memmap_init_zone tries to initialize padding of a # section even when it is outside of the given pfn range because there are # code paths (e.g. memory hotplug) which assume that the full worth of # memory section is always initialized. # # In this particular case, though, such a range is already intialized and # most likely already managed by the page allocator. Scribbling over # those pages corrupts the internal state and likely blows up when any of # those pages gets used. # # Reported-by: Robert Shteynfeld <robert.shteynfeld@gmail.com> # Fixes: 2830bf6f05fb ("mm, memory_hotplug: initialize struct pages for the full memory section") # Cc: stable@kernel.org # Signed-off-by: Michal Hocko <mhocko@suse.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 4aa9fc2a435abe95a1e8d7f8c7b3d6356514b37a # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x95E793E3 # 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 # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/exceptions-64e.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/exceptions-64e.S:587: Error: unrecognized opcode: `mc_btb_flush' make[3]: * [/kisskb/src/scripts/Makefile.build:367: arch/powerpc/kernel/exceptions-64e.o] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:492: arch/powerpc/kernel] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1043: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:152: sub-make] Error 2 Command 'make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 # Build took: 0:03:10.454638
