Going all in on crtc state? I suppose migrating away from private_flags
could easily start in i915 before that. Seems rather independent.

I guess it's __intel_get_crtc_scanline() and:

	vblank = &crtc->base.dev->vblank[drm_crtc_index(&crtc->base)];
	mode = &vblank->hwmode;

	if (mode->private_flags & I915_MODE_FLAG_GET_SCANLINE_FROM_TIMESTAMP)

that gives me the creeps in reviewing all that.

There's also [1] adding new uses for private_flags; I think there were
issues in getting at the right crtc state on some of those paths, but I
forget the exact details. Ideas?

BR,
Jani.
