This is not the case here. While it is true that all  CPM  interrupts
share  one  SIU  interrupt,  it  is  IMHO  wrong  to  speak of shared
interrupts - they are just on another interrupt controller. All  that
needs  to  be  done is hiding the details of the interrupt controller
architecture from the user who just wants to  register  an  IRQ  with
either the RT or the Linux part.

I'll be happy to adapt your solution if you come up with a better one.

For every complex problem, there is a solution that is simple,  neat,
