I bet a million to one it "just" needs to be reworked into a hierarchical
interrupt controller with the GPIO at the level below the irqchip adding
level semantics.

I did provide an example of how to do this in the ixp4xx patchset, but
if you don't have the hardware at hand I would not recommend trying
it.

With the goal of getting a better build for ARM32 maintenance I
think this is a lesser evil, so:
