I already put in these

1)      xen/events: fix unmask_evtchn for PV on HVM guests
2)      xen: missing includes
3)      xen: update xen_add_to_physmap interface
4)      xen: Introduce xen_pfn_t for pfn and mfn types
5)      xen: clear IRQ_NOAUTOEN and IRQ_NOREQUEST
6)      xen: allow privcmd for HVM guests

in my tree as they also impact/help the PVH domains which works for
x86 (Well, not all of them). They are in my stable/for-linus-3.7 git tree
(git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git)
and also in #linux-next.


If it would make reviewing easier, I would recommend you rebase
your tree on top of the stable/for-linus-3.7 and just post them
as it would make the number of patches smaller.

Or alternatively, if the ARM maintainer wishes - just give you
the OK and we can figure out how/who is going to do the git-fu.
