[PATCH 0/3] drm: Add CRTC-id based ioctls for vblank query/event

[Keith Packard]

Here's an updated series for the proposed new IOCTLs. Major changes
since last time:

 * Leave driver API with 32-bit vblank counts
 * Use ktime_t instead of struct timespec.
 * Check for MODESETTING before using modesetting APIs
 * Ensure vblank is running in new get_sequence ioctl

There are other minor changes noted in each patch.
