This # include was added solely for the pseudo-random definitions, which have # nothing to do with the rest of the definitions in this file but are # still there for legacy reasons. # # This patch moves the pseudo-random parts to linux/prandom.h and the # percpu.h include with it, which is now guarded by _LINUX_PRANDOM_H and # protected against recursive inclusion. # # A further cleanup step would be to remove this from # entirely, and make people who use the prandom infrastructure include # just the new header file. That's a bit of a churn patch, but grepping # for "prandom_" and "next_pseudo_random32" "struct rnd_state" should # catch most users. # # But it turns out that that nice cleanup step is fairly painful, because # a _lot_ of code currently seems to depend on the implicit include of # , which can currently come in a lot of ways, including # such fairly core headfers as . # # So the "nice cleanup" part may or may never happen. # # Fixes: 1c9df907da83 ("random: fix circular include dependency on arm64 after addition of percpu.h") # Tested-by: Guenter Roeck # Acked-by: Willy Tarreau # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 c0842fbc1b18c7a044e6ff3e8fa78bfa822c7d1a # < make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # < make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:4295:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:4297:warning: override: reassigning to symbol UML_NET_SLIP .config:4300:warning: override: reassigning to symbol UML_NET_MCAST .config:4302:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 80 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/signal.c: In function 'sig_handler_common': /kisskb/src/arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2976 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/arch/um/os-Linux/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/lib/lz4/lz4hc_compress.c: In function 'LZ4HC_compress_generic': /kisskb/src/lib/lz4/lz4hc_compress.c:579:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ LINK linux ERROR: modpost: "devm_platform_ioremap_resource" [drivers/iio/adc/adi-axi-adc.ko] undefined!
