Hi Manuel,

I changed the way the GPIO events are passed to userland and
gpio-intr-kqueue won't work anymore.

I'm working in its replacement and I will soon post the patches and
(hopefully) a comprehensive guide to get it working.

There is also an ongoing work to change interrupt support on ARM which
I need to catch up.

Regards,
Luiz
