Yes, because I didn't plan for accel to have any core code at this stage. But according to your other comments, this will probably change (unless someone thinks otherwise).

Feel free to add me (or don't) to this entry as you see fit.

Add a new Kconfig for the accel subsystem. The Kconfig currently contains only the basic CONFIG_ACCEL option that will be used to decide whether to compile the accel registration code as part of the drm core functionality. I have taken the liberty to appropriate the dri-devel mailing list and the dri-devel IRC channel for the accel subsystem.
