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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 4aa9fc2a435abe95a1e8d7f8c7b3d6356514b37a # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- /kisskb/src/arch/mips/boot/dts/xilfpga/nexys4ddr.dts:109.16-112.8: Warning (i2c_bus_reg): /i2c@10A00000/ad7420@4B: I2C bus unit address format error, expected "4b" FIT description: Linux 5.0.0-rc4-g4aa9fc2a435a Created: Tue Jan 29 07:59:14 2019 Image 0 (kernel@0) Description: Linux 5.0.0-rc4-g4aa9fc2a435a Created: Tue Jan 29 07:59:14 2019 Type: Kernel Image Compression: gzip compressed Data Size: 4502220 Bytes = 4396.70 KiB = 4.29 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x808554f0 Hash algo: sha1 Hash value: 22cb918ca25ffc0c0525a0c53fcda1227911213d Image 1 (fdt@boston) Description: img,boston Device Tree Created: Tue Jan 29 07:59:14 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Tue Jan 29 07:59:14 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Tue Jan 29 07:59:14 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 509ce58e44c561d54539e64e9d4b47054e696fc6 Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/linus_mips-defconfig_mipsel # Build took: 0:01:27.297798
