No need to bounce between core and driver. Just,

	intel_iommu_domain_alloc(IOMMU_DOMAIN_UNMANAGED);

and fully initialize it before return.
If you are going to do that then intel_iommu_domain_alloc() should
fully initialize the domain, not here.
I've also considered what Baolu described, but it requires to do some
extra initialization which is duplicated with iommu_domain_alloc().
So I chose this simple way.

Okay, got you.

Once Jason's paging domain and Robin's bus->iommu_ops retirement series
have landed, the VT-d driver will need some refactoring. Therefore, I'm
fine with you using a simpler approach here. I'll refactor everything
later.

Best regards,
baolu
