Introduce a new iommu_domain op to create domains owned by userspace, e.g. through iommufd. These domains have a few different properties compares to kernel owned domains:
- They may be MANAGED domains, but created with special parameters. For instance aperture size changes/number of levels, different IOPTE formats, or other things necessary to make a vIOMMU work
what is *MANAGED* domain?
today we only have the separation between DMA domain and UNMANAGED domain.
soon with Jason's cleanup all domains are called UNMANAGED.
It should be UNMANAGED domain.
