Centos 7 is not yet released so it's more easy to get patch in. I don't
know what will be position when the guest is shipped.
I bet they will still want to support 64KB with older Xen (i.e where
64KB grant is not supported).
Anyway, I don't expect to see the 64KB grants support before next year
as my TODO list is already pretty full. So let's talk about it when I
(or someone else) will send an RFC to extend the grant size.
