agd5f drm-next-3.18-wip + patch is still bad.

Bad can be a bit variable, but I would call it as one of the better bads and
the vram usage is closer to a good - pic to follow.

Another observation - On good or bad the demo takes a while to get going.

Time to start of normal rendering on this patched kernel is around 2m5s

If I wiggle the window around while it's loading/stuck = 1m23s
