Ah, ok. I suggested earlier in the series to use xe_ggtt_node_allocated
but I see now this function is removed. Before I can give an RB I'd like
to apply the entire series to a branch to make sure I understand this
change. The mbox as is doesn't apply to drm-tip. Any chance you can
rebase this series?
