Anything _relying_ on order-3 pages being available to impress friends/customers is a lie.
BTW, you do understand that on PowerPC right now, an Ethernet frame holds 65536*8 = half a MByte , right ? So any PowerPC host using mlx4 NIC can easily be bringed down, by using a few TCP flows and sending out of order packets. That is in itself quite scary.
