From: Ville Syrjälä <[email protected]> Since commit 4dfd648 ("drm: Use vblank timestamps to guesstimate how many vblanks were missed") the vblank code can cook up a frame counter value based on the vblank timestamps (as long as they're accurate), so there's no longer any need to keep vblank interrupts enabled on gen2 when no one is interested in them. So let's opt into the immediate disable scheme on gen2 as well.
