This is a well-structured 9-patch series from Thomas Zimmermann that addresses a real semantic problem: `DRM_IOCTL_WAIT_VBLANK` (and the newer `CRTC_GET_SEQUENCE`/`CRTC_QUEUE_SEQUENCE` ioctls) being available on devices that only have software-simulated vblank timers (no hardware vblank interrupt). For such devices, waiting for vblank is meaningless since the timer is not synchronized to any display refresh.
The approach is clean: patch 1 renames the init function to `drmm_vblank_init()` with a flags parameter, patch 2 adds the `DRM_VBLANK_FLAG_SIMULATED` flag and the ioctl filtering, and patches 3-9 convert the known simulated-vblank drivers. The series is logically ordered and easy to bisect.
**Overall: looks good.** A few minor observations below, none blocking.
