+ * In linux userspace virtual == user == phys addresses.
+ * Physical addresses also being the same is wrong, but there is no general way
+ * of converting userspace addresses to physical as what appears to be
+ * contiguous in userspace is physically fragmented.
+ * Currently only the DMA memory is special-cased, but its conversion to bus
+ * addresses is done in phys_to_bus.
+ * This is known to break virtio as it is passing phys addresses to the virtual
+ * device.
