We will want to take a hack limiting the maximum order for compound page allocated to 0 to avoid large multi-page skb allocations consuming too much swiotlb resource (and making performance worse). We have just switched XenServer to 3.10 and we are seeing odd user space crashes in a CentOS 6.4 constructed initrd so I would recommend not switching to 3.10 until we understand what is going on here.
