Albert, it looks like I forgot to add you to the CC on this email. 
Sorry! Could you please take a look at this series and tell me what you 
think? If you need a resend just let me know.

Also note that this series is a dependency for PCIe support on 64-bit 
Tegra systems; I guess either Tom Warren would be looking for an ack so 
he can apply the series to the Tegra tree, or perhaps if you just apply 
the whole series, he can base his branch on the branch where you apply this.
