I think it should not be "linux,..." since the description can
well be OS independent. I don't have a good idea for a generic
name, but it's not very important.

The main missing piece in the generic irqchip code at the moment
is support for the linear irqdomain. Once we have that, a lot of
code can be simplified significantly.
