That patch is a part-2 of a 3-part patch set. In order, this should
have been v10: applied as:

   http://patchwork.ozlabs.org/patch/459804/
   http://patchwork.ozlabs.org/patch/459803/
   http://patchwork.ozlabs.org/patch/459802/

The mail thread for the 3-part patch set was here
   http://www.spinics.net/lists/sparclinux/msg13785.html

I noticed that the existing dates on the iommu commits were also odd:

We have had many discussions of this patch set since March 12,
and the correct version should have been v10, dated something
after Apr 9, and acked by Benjamin Herrenschmidt.
