Note that there's a functional change buried in this patch wrt the ilk dmar workaround: We now only idle the gpu while tearing down the dmar mappings, not while clearing the gtt. Keeping the current semantics would have made for some really ugly code and afaik the issue is only with the dmar unmapping that needs a fully idle gpu.
