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-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 4aa9fc2a435abe95a1e8d7f8c7b3d6356514b37a # < make -s -j 80 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n | make -s -j 80 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1336:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
