We have platforms where we need to ensure that certain interrupts can't
be requested.

Unfortunately, that was never properly dealt with when genirq came
along, and we're pretty much stuck with this situation: going through
and working out what the restrictions were is a much bigger problem
than it was when genirq first happened.  I don't see how we could
sanely fix this now.

What we should probably at least do is work out a way that we can kill
that ifdef, so we don't have the same hack appearing in many drivers.

according to speedtest.net.
