The system is required to emulate unaligned accesses, even if the hardware does not support it. The resulting trap may or may not be more efficient than the qemu slow path. There are linux kernel patches in flight to allow userspace to query hardware support; we can re-evaluate whether to enable this by default after that. In the meantime, softmmu now matches useronly, where we already assumed that unaligned accesses are supported.
