With this patch we provide the functionality to initialize the Xen-SWIOTLB late in the bootup cycle - specifically for Xen PCI-frontend. We still will work if the user had supplied 'iommu=soft' on the Linux command line. Note: We cannot depend on after_bootmem to automatically determine whether this is early or not. This is because when PCI IOMMUs are initialized it is after after_bootmem but before a lot of "other" subsystems are initialized.
