Hi all, After merging the akpm-current tree, today's linux-next build (arm64 randconfig) failed like this: arch/arm64/include/asm/neon-intrinsics.h:33:10: fatal error: arm_neon.h: No such file or directory Also, the nds32 defconfig build failed like this; arch/nds32/include/asm/nds32.h:13:10: fatal error: nds32_intrinsic.h: No such file or directory Presumably caused by commit 6f4266a78a4e ("kbuild: decouple build from userspace headers") -- Cheers, Stephen Rothwell
