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. -- -keith
