Move the list of globals out of iommu and move them to a linked list in the device instead. But that's not the clever part. The clever part is we painstakingly dynamically allocate all of the global objects and track them so we can automatically clean them up when the device is removed, thereby saving quite a bit of pain. Also, by dynamically allocating the memdescs we can skip creating lots of static memory descriptors that may or may not be used for any given target.
