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/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 4aa9fc2a435abe95a1e8d7f8c7b3d6356514b37a # < make -s -j 48 ARCH=sh O=/kisskb/build/linus_rsk7201_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- rsk7201_defconfig # make -s -j 48 ARCH=sh O=/kisskb/build/linus_rsk7201_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1318:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1321:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1324:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1327:2: warning: #warning syscall statx not implemented [-Wcpp] <stdin>:1333:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1336:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2a/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2a/../../entry-common.S:385: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2a/../../entry-common.S:388: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here /kisskb/src/drivers/sh/clk/cpg.c: In function 'r8': /kisskb/src/drivers/sh/clk/cpg.c:41:2: warning: passing argument 1 of 'ioread8' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:29:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r16': /kisskb/src/drivers/sh/clk/cpg.c:46:2: warning: passing argument 1 of 'ioread16' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:30:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r32': /kisskb/src/drivers/sh/clk/cpg.c:51:2: warning: passing argument 1 of 'ioread32' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:32:21: note: expected 'void ' but argument is of type 'const void ' Image Name: Linux-5.0.0-rc4+ Created: Tue Jan 29 08:31:29 2019 Image Type: SuperH Linux Kernel Image (gzip compressed) Data Size: 1542443 Bytes = 1506.29 KiB = 1.47 MiB Load Address: 08001000 Entry Point: 08002000 Image arch/sh/boot/uImage is ready Completed OK # rm -rf /kisskb/build/linus_rsk7201_defconfig_sh4 # Build took: 0:00:19.264227
