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/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 c0842fbc1b18c7a044e6ff3e8fa78bfa822c7d1a # < make -s -j 10 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig KCONFIG_SEED=0x231F8B88 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=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 # < make -s -j 10 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 10 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:3763:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 10 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /bin/sh: 1: zstd: not found cat: write error: Broken pipe make[3]: *** [/kisskb/src/arch/x86/boot/compressed/Makefile:150: arch/x86/boot/compressed/vmlinux.bin.zst] Error 127 make[3]: *** Deleting file 'arch/x86/boot/compressed/vmlinux.bin.zst' make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/arch/x86/boot/Makefile:115: arch/x86/boot/compressed/vmlinux] Error 2 make[1]: *** [arch/x86/Makefile:265: bzImage] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 10 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc8 # Build took: 0:05:13.832056
