Are you rolling or spraying?
In my experience, if your spraying, you don't need to do anything but spray it with your choice of paint. If your rolling it, it may need a couple coats, but that smoke damage will not come through if the paint covers well. The ONLY reason anyone might or should prime over smoke damage is to seal in the smell, otherwise what's the purpose? It doesn't bleed through like nicotine or water damage stains.
