yes I think it should be done, unless Anatolij has a really good reason
these variables are defined all over the place.

I have patches ready to remove allot more of these globals. Yet I have
to test them. (and as this is cross arch / several patches this gona take
some time)

Simon: I intend to remove you cursors stuff from tegra since it is not
used anywhere. What is the intention of the cursor stuff?

The amba driver is scheduled for removal as well since it is not used.
