Your email client seems to set 'Reply-to:' to point to everyone on the 'Cc:' field, but not yourself, which is kind of weird. I've manually fixed it on this reply by moving everyone to the 'Cc:' field and setting you on 'To:'.

It's not that Arm doesn't have ZONE_DEVICE, it's just that the approach used here won't work correctly on an Arm Xen dom0 as-is. This is due to the usage of an identity second stage translation in order to workaround the lack of an IOMMU in some Arm boards. It can be made to work on Arm, but will likely require someone from the Arm side doing that.
