They can use new function get_irqfunc_irq(), similar to the existing 
method of getting pt_regs for the tiny number of users who need that 
sort of info, when pt_regs was removed.

But after having gone over, literally, every single interrupt handler in 
the kernel, I can safely say that 99.8% never reference that argument, 
and 0.1% that do already have the same information via another route.

That leaves only a few drivers that need it without modification, and 
even fewer drivers that need it after modification.
