Now this is a pretty big patch ...

The big question that enters my mind is *why* is the da850 and
dm365 not using SPARSE_IRQ?

As it happens I'm on an ARM32 crusade to get everyone and its
dog to use, among other things, SPARSE_IRQ.

I would feel *much* *much* better if there was first a patch
to the DaVinci tree to turn on SPARSE_IRQ for this subarch,
and then this patch may look a bit different, maybe smaller
I take it?

Is this totally unattainable?
