The wiki page point to a linux 3.7 whit linaro patches and xen patches.

It's seems the Arndale support is nearly completed on 3.9. It's a matter
of about ten patches.

I would prefer to stick on linaro tree to avoid to maintain our own
Linux Arndale tree. We can switch to a linux upstream once the Arndale
is fully supported.
