Is there really no way to avoid compat ioctls? was I delusional in
thinking there was?

If you use pointers in your interfaces in any way, no.

And for this drm_radeon_info thing the pointer is "pointless",
you're just returning 32-bit values to the user, just use
a u32 inside of the drm_radeon_info structure for the kernel
to place the result in.

The plan for that was to expand it later, for now 32-bit was all we used.
