This makes use of the new "memory registering" feature. The idea is to provide the userspace ability to notify the host kernel about pages which are going to be used for DMA. Having this information, the host kernel can pin them all once per user process, do locked pages accounting (once) and not spent time on doing that in real time with possible failures which cannot be handled nicely in some cases. This adds a prereg memory listener which listens on address_space_memory and notifies a VFIO container about memory which needs to be pinned/unpinned. VFIO MMIO regions (i.e. "skip dump" regions) are skipped. The feature is only enabled for SPAPR IOMMU v2. The host kernel changes are required. Since v2 does not need/support VFIO_IOMMU_ENABLE, this does not call it when v2 is detected and enabled. This enforces guest RAM blocks to be host page size aligned; however this is not new as KVM already requires memory slots to be host page size aligned.
