Hi, this patch series implements stackable dma_ops on x86. This is useful to be able to fall back to a different dma_ops implementation if one can not handle a particular device (as necessary for example with paravirtualized device passthrough or if a hardware IOMMU only handles a subset of available devices). The patch series is split to change the different iommu implementations in different patches. This should make it easier for the specific maintainers to review the part that changes their code.
