Yeah, I thought about it and it's possible (but not so easy). parisc has IOMMU merging helper code and two parisc IOMMUs use it. ia64 sba_iommu is almost identical to parisc code. x86_64 gart, power, and alpha do in their own way. But I think that we can merging helper code useful for all. I'll see what we can have after fixing the mering problem. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
