Doesn't work very well when you have sun4c_irq.c, sun4m_irq.c,
and sun4d_irq.c sitting right next to them.

Sparc32 is miles away from sparc64 in terms of being easy to make
use generic IRQs.

It's a lot of hard work and testing of which I have to rely upon
helpers to perform.  The sparc arch directory consolidation in no way
makes me want to do that work any more or any less, no matter how many
times I open up irq_64.c :-)
