Yikes. I'll button this up. I'm surprised that I need to import the
namespace of my own module... but I don't have a strong enough
understanding of what all is going on.
Also, allmodconfig never compiles for me, so I can't really test it:
make W=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j$(nproc)
...

I'll try it without cross-compile and see if I have better luck.
