There are some structs here which use the name 'cpu' for
a 'struct omap_mpu_state_s *', which leads to ugliness
like s->cpu->cpu->env. (We shouldn't be trying to fix that
here, just a passing comment.)

Acked-by: Peter Maydell <peter.maydell@linaro.org>

(For the avoidance of doubt, acked-by for me means "I've
looked at this patch and it looks generally but I have not
tested it or otherwise given it the more detailed scrutiny
I would for a reviewed-by tag".)

Thanks, applied to qom-next:
http://repo.or.cz/w/qemu/afaerber.git/shortlog/refs/heads/qom-next

Now that we have qom-next, we are no longer limited to the concept of
self-contained series so I can try to turn that into s->mpu->cpu->env
the weekend. Not perfect either, but better distinguishable.
