Mika Kuoppala 7b01e260a6 drm/i915: Set sync_seqno properly after seqno wrap ... i915_gem_handle_seqno_wrap() will zero all sync_seqnos but as the wrap can happen inside ring->sync_to(), pre wrap seqno was carried over and overwrote the zeroed sync_seqno. When wrap is handled, all outstanding requests will be retired and objects moved to inactive queue, causing their last_read_seqno to be zero. Use this to update the sync_seqno correctly. RING_SYNC registers after wrap will contain pre wrap values which are >= seqno. So injecting the semaphore wait into ring completes immediately. Original idea for using last_read_seqno from Chris Wilson.
