For userspace tools, I'm inclined to agree, but this is just documentation so it shouldn't cause any issues with cross building. But to be clear: I'd still prefer it to be part of the man-pages project, and would only consider it for inclusion in the kernel tree if it was rejected for being too CPU-specific. Will
