Hi, here is the second version of the patch-set to introduce an explicit TLB-flushing interface to the IOMMU-API. This version changed the interface quite a lot compared to the first version.
This version does not change the semantics of the iommu_map() and iommu_unmap() functions anymore. The reason is that the semantic-change doesn't make sense for iommu_map(), as this path does not require a TLB-flush in almost all cases. And only changing the semantics of the iommu_unmap() path would introduce an asymmetry to the IOMMU-API, which makes it harder to use. This series introduces the new function iommu_unmap_fast() instead, which is allowed to return with dirty TLBs. The three functions for TLB-flushing have not changed compared to the first version of this patch-set. Since the iommu_map()/unmap() functions don't change their semantics anymore, I've also dropped all patches which convert the existing users. Please review.
