I like this patch quite a bit.  For one thing, it fixes the target
dcache for the coming multi-target work :-)

On the whole I would prefer we not add new object-style macros like
this.  (Actually I'd really like it if we got rid of the existing ones
too...)  Writing out the expansion in the few places it is used seems
better to me.

Here you don't need to call address_space_data, since ARG is the dcache
that was passed in.
