Yes, I haven't seen it, and now that I have I don't like it.

FIQs should be an entirely separate number space from IRQs, as we
may want to totally decouple them from the IRQ stuff (we probably
should have already done this when genirq came along.)

About the only stuff FIQs use is the enable/disable_irq as a short
cut to dealing with the mask registers.
