I’m working on virtio-IOMMU interrupt remapping for Spectrum OS [1],
and am running into a problem.  All of the current interrupt remapping
drivers use __init code during initialization, and I’m not sure how to
plumb the struct virtio_device * into the IOMMU initialization code.

What is the proper way to do this, where “proper” means that it doesn’t
do something disgusting like “stuff the virtio device in a global
variable”?
