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-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 c0842fbc1b18c7a044e6ff3e8fa78bfa822c7d1a # < make -s -j 80 ARCH=arm O=/kisskb/build/linus_viper_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- viper_defconfig # < make -s -j 80 ARCH=arm O=/kisskb/build/linus_viper_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_viper_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_viper_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- Completed OK # rm -rf /kisskb/build/linus_viper_defconfig_arm-gcc4.9 # Build took: 0:00:53.799421
