You could have given a lot more information to that question!

How new a feature is it? Does this mean that this patch must go in before
3.8 releases or is it a fix against a patch that is only in Andrew's tree?
If the patch is only in Andrew's tree, which one is it and should this be
folded in as a fix?

On a semi-related note; is there a plan for backporting highmem support for
the LTSI kernel considering it's aimed at embedded and CMA was highlighted
in their announcment for 3.4 support?
