Sorry! didn't get that quite well. When you meant "per-group default-domain patch-set", do you mean the patch set that I am working on which changes iommu group default domain dynamically by writing to sysfs file?
If so, they don't use these functions so it should be ok to remove them. If you meant some other patch set, could you please point me to them?

Sai
