ping on this patch too for pci/host-thunder. Do you think we can mark
this stable for 4.11? Since there is a dependent patch not yet in
stable (b77d537d00, should be added to stable too) there might be
conflicts. But maybe this could be figured out once the patch is
considered for inclusion into stable.
