I think that's going to break FBC.
Probably the best thing to do is kill adjusted_x/y and instead replace
them with something better in the fbc code. That something being
essentially plane_state->main.x/y. Though I think they need to get
plumbed through the fbc state_cache, and I think we should kill off the
FBC crtc->base.y usage while we're at it. So maybe we can just compute
the final fence_y_offset in intel_fbc_update_state_cache() and stick
that into the state_cache. Cc:ing Paulo for his thoughts...
