It is. Or was. We use the handler_data field to hold the vcpu
information, but that's also used by the chained interrupt handler to
find out which secondary it is.

But this patch is wrong anyway, as it entirely breaks secondary GICs (I
found out when I merged this with a patch from Jon Hunter fixing some
other related stuff). Took me hours to get an EB up and running!

I have a working version now, which makes this patch irrelevant.

Thanks,
