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?
