Except for the what appears to be instability of the irq numbers on
simpler configurations I don't have a problem with it.
I agree that's a bit annoying and I beleive it can be fixed. In
additionm I'd like to look into exposing the domain/HW number -> virq
mapping somewhere in sysfs maybe.
Until we find a solution for the user space side of things we seem to
need the unsigned int irq number for user space. Now I don't want
people mapping back and forth which is why I don't intend to provide a
reverse function.
Ok.
But of course there will be a for_each_irq in the genirq layer so if
people really want to they will be able to go from the linux irq to
an irq_desc. But we don't have to export that generically (except
possibly something for the isa irqs).
Ok.
Ben.
