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-

ping for review.
Let me know if there's anything that needs to be done, thanks!

drm_vblank_count() has a u32 type returning what is a 64-bit vblank count.
The effect of this is when drm_wait_vblank_ioctl() tries to widen the user
space requested vblank sequence using this clipped 32-bit count(when the
value is >= 2^32) as reference, the requested sequence remains a 32-bit
