Right now there are no knobs to disable it, since last time I checked,
people were inclined to
solve that by adding a machine type that does not do irqchip in
kernel, if wanted.

However, since it is probably not going to reach 0.12 anyway, we can
come up with a patch
that fixes msix, and bundle in this series before I actually enable
the irqchip (which is one
of the last patches)
