On the walls and optionally on the ceiling if it's high. I was in Studio A at Criteria / Hit Factory earlier this year and the entire ceiling was covered with deep skyline diffusors. The room was surprisingly live, but the liveness had no hint of resonance or emphasizing only some frequencies. This way the engineers can easily adjust the amount of room tone picked up by putting the microphones closer or farther from the performers. The diffusors ensure that the room tone is neutral, not boxy or "small" sounding.
The point of diffusion in a live room is to avoid flutter echo but without adding absorption which would reduce the reverb time. How much diffusion is useful, and where it will work best, depends entirely on the size of the room.
