I think Yao was agreeing with the patch. I agree with the change
as well, so you can commit that part right away.

I think we should fix gdbarch.h to include frame.h instead, which
effectively means adjusting gdbarch.sh. The solution you chose seems
to be relying on an indirect include, which we really really try
to avoid. Yao's question is a good example of one of the reasons
why we avoid that; but there is also the fact that not everyone
will need frame.h's declarations.

Same here, dcache.h should be the one including target.h.
