This default handler allows concepts that on x86 would be handled using NMIs to be realized on ARM. Credit: This patch is a near complete re-write of a patch originally provided by Anton Vorontsov. Today only a couple of small fragments survive, however without Anton's work to build from this patch would not exist.
