Hi, sorry about that. I was away for a month, and forgot about this.

Tested just now. It seems good, GPIO interrupts work under 3.2
with this patch same as they do if I revert the genirq change.

I noticed that something else is broken for me under 3.2 (my FPGA driver
fails to load bitstream) compared with 3.0, but that is also broken with
genirq reverted so I think it's a separate issue and your patch is good.

So,
