RFC because it *still* doesn't work, just like v1.

However this time the changes are extremely minimal, and now
I really *really* don't understand why they don't work, because
as far as I can tell the new locking is *identical* with the
current i/o path.

In particular, the actual access happens between _prepare
and _complete, just like before.  Indeed, since this doesn't
work as-is, then I can't believe the atomic path works either.

I have included the TLB_BSWAP stuff just so that the
patch set is self-contained.

I did experiment with qemu_ram_addr_from_host_nofail(), but
an assertion for equality with addr + iotlbentry->addr does
not trigger.  As expected, really, since that's what the i/o
path uses.  One more cleanup for the atomics path...

Ideas?
