Ok, I'll bite. I've been telling people for ages what the right solution
for this is, but apparently sometimes you need to do it yourself if you

Patch follows to introduce compat_u64. Please redefine your data
structure as
typedef struct drm_radeon_setparam32 {
int param;
compat_u64 value;
} drm_radeon_setparam32_t;
