It is probably because I patched the wrong map_irq() function,
I am trying to detect which one you are _actually_ using, if
the patch below fails I will patch them all (which is what I
have to do anyway).

Please give this a go - this _has_ to make a difference, it is not
correct to leave map_irq() pointers as __init memory, IRQ routing
for modules can't work.

This works for mainline git too.

If you have another round that fixes all subarches, I will try it on a 
PC164 too.
