Subject: Re: [PATCH FOR-4.5] xen: arm64: Handle memory banks which are not 1GB aligned

Ian,
This one seems to workaround the issue with pagetable setup in Xen we
saw earlier here:
http://lists.xen.org/archives/html/xen-devel/2014-10/msg01013.html
However, it's now breaking in Dom0 when trying to parse device tree.
I'll look at this over the weekend. Here is the boot log.
