Rob, Are you able to take this patch now for 3.7, or should it be held off until the Tegra PCIe driver is re-written and requires this functionality (in which case I'd expect to take this through the Tegra tree at that time). For reference, it's at http://patchwork.ozlabs.org/patch/173497/. Thanks.
