Let's see if we have all the kinks worked out and full-ppgtt now works reliably on gen7 (Ivybridge, Valleyview/Baytrail and Haswell). If we can let userspace have full control over their own ppgtt, it makes softpinning far more effective, in turn making GPU dispatch far more efficient and more secure (due to better mm segregation).
