I think you have my Acked-by for this case already (from Aug 20).  And
feel free to copy me on anything you like; my delete key works well :)

I'm OK with merging things through my tree.  It just seemed like there
was a lot of recent Tegra activity that included a few Tegra PCI
changes, and no benefit to trying to split the PCI stuff from the
non-PCI stuff.  Hopefully it will calm down, because I don't have time
to be in the middle of major Tegra stuff.
