Why do you need to bound the size of the string?
It is passed by the user, it is good to be clear about the max size?

This patch removes the implicit domain_crash() from iommu_map(),
unmap_page() and iommu_iotlb_flush() and turns them into straightforward
wrappers that check the existence of the relevant iommu_op and call

This patch modifies the declaration of the entry points to the IOMMU
