Add user access API for linux. On 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.
