I missed an interaction with the free page float # count used to ensure we can support atomic allocations. If one type of # chunk has no free pages, but the other has enough to satisfy the free # page float requirement, we will not repopulate the free pages for the # former type of chunk. This led to the sporadically failing atomic # allocations" # # Link: https://lore.kernel.org/linux-mm/20210324190626.564297-1-guro@fb.com/ [1] # Link: https://lore.kernel.org/linux-mm/20210401185158.3275.409509F4@e16-tech.com/ [2] # Link: https://lore.kernel.org/linux-mm/CAL3q7H5RNBjCi708GH7jnczAOe0BLnacT9C+OBgA-Dx9jhB6SQ@mail.gmail.com/ [3] # # * 'for-5.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: # percpu: make pcpu_nr_empty_pop_pages per chunk type # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 52e44129fba5cfc4e351fdb5e45849afc74d9a53 # < make -s -j 80 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- multi_v7_defconfig # < make -s -j 80 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- help # make -s -j 80 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- olddefconfig # make -s -j 80 ARCH=arm O=/kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- In file included from /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/tm.h:23, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:15, from /kisskb/src/scripts/gcc-plugins/arm_ssp_per_task_plugin.c:3: /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/config/elfos.h:102:21: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] fprintf ((FILE), "%s"HOST_WIDE_INT_PRINT_UNSIGNED"\n",\ ^ /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/config/elfos.h:170:24: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] fprintf ((FILE), ","HOST_WIDE_INT_PRINT_UNSIGNED",%u\n", \ ^ In file included from /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/tm.h:44, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:15, from /kisskb/src/scripts/gcc-plugins/arm_ssp_per_task_plugin.c:3: /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/../lib/gcc/arm-linux-gnueabi/4.9.4/plugin/include/defaults.h:126:24: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] fprintf ((FILE), ","HOST_WIDE_INT_PRINT_UNSIGNED",%u\n", \ ^ cc1plus: warning: unrecognized command line option '-Wno-format-diag' /kisskb/src/arch/arm/crypto/ghash-ce-glue.c: In function 'ghash_do_update': /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:67:44: warning: passing argument 4 of 'pmull_ghash_update_p64' from incompatible pointer type pmull_ghash_update_p64(blocks, dg, src, key->h, head); ^ /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:45:17: note: expected 'const u64 (*)[2]' but argument is of type 'u64 (*)[2]' asmlinkage void pmull_ghash_update_p64(int blocks, u64 dg[], const char *src, ^ /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:69:43: warning: passing argument 4 of 'pmull_ghash_update_p8' from incompatible pointer type pmull_ghash_update_p8(blocks, dg, src, key->h, head); ^ /kisskb/src/arch/arm/crypto/ghash-ce-glue.c:48:17: note: expected 'const u64 (*)[2]' but argument is of type 'u64 (*)[2]' asmlinkage void pmull_ghash_update_p8(int blocks, u64 dg[], const char *src, ^ /kisskb/src/drivers/firmware/qcom_scm-smc.c: In function 'scm_smc_call': /kisskb/src/drivers/firmware/qcom_scm-smc.c:94:9: warning: missing braces around initializer [-Wmissing-braces] struct arm_smccc_args smc = {0}; ^ /kisskb/src/drivers/firmware/qcom_scm-smc.c:94:9: warning: (near initialization for 'smc.args') [-Wmissing-braces] /kisskb/src/drivers/firmware/qcom_scm-legacy.c: In function 'scm_legacy_call': /kisskb/src/drivers/firmware/qcom_scm-legacy.c:139:9: warning: missing braces around initializer [-Wmissing-braces] struct arm_smccc_args smc = {0}; ^ /kisskb/src/drivers/firmware/qcom_scm-legacy.c:139:9: warning: (near initialization for 'smc.args') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/linus_multi_v7_defconfig_arm-gcc4.9 # Build took: 0:03:41.179335
