It looks like a general review of the 64-bit widening patch is needed.

 * drm_crtc_accurate_vblank_count has a 32-bit return, and uses a 32-bit temporary
 * drm_wait_one_vblank uses a 32-bit temporary.

I looked at every 'u32' in drm_vblank.c; it would be good to have more
eyes check this.

Thanks for finding the first one.
