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")

I'm seeing several reports against that patch so I dropped it for now.
