Yes, this should be common over architectures.  Anyway, I expect there
to be some discussion until we've reached that point, so for now I'll
rebase patches 5 and 6 to not require this patch, and will send one
to kill the unused x86 implementation.  Whatever is the final outcome
can be implemented on top.
