Ok here's feedback already, I haven't had any issues with "random" desktop
freezes since yesterday since I applied the patch

So basically I can now use desktop for the most part without nodma globally
enabled, I will report back if it turns out not to be the case.

With all those 3 patches applied, Rocket League successfully launched 2 times
out of 10, so I could say that 80% of time it will still provoke the SDMA type
hang. Unfortunately this is the only game that I know that provokes the SDMA
hang compared to ring_gfx hangs on Starcraft II and Rise of the Tomb Raider.
