Omitted-fix: c7bd8a1f45ba ("iommu/apple-dart: Handle DMA_FQ domains in attach_dev()")
             - Apple Dart not supported

Upstream Status: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

Testing: A mix of fio jobs, and various stress-ng io stressors (--hdd, --readahead, --aio, --aiol, --seek,
         --sync_file) run with strict and lazy translation modes on amd, intel, and arm systems. pgtbl_v2
         tested on AMD Genoa host

Conflicts: Should be noted in individual commits. In particular one upstream merge in 6.4, 58390c8ce1bd, had a rather
           messy merge conflict resolution set, so a number of commits have those cleanups added in here.

Summary of Changes

        Rebase through v6.5 with a good portion of v6.6 as well (minus the
	dynamic swiotlb mempool support, per numa dma cma support, and arm
	+ mm tlb invalidate changes). For iommufd changes there are
	backports of the underlying functionality in iommufd, but I have left
	the vfio commits that will eventually make use of it for Alex.
	
Highlights
	* AMD GA Log Overflow refactor and PPR Log support
	* AMD v2 page table support
	* AMD v2 5 level guest page table support
	* Various cleanups and fixes
	* Sync ipmmu-vmsa in preparation for Renesas support  (config not enabled)
	* Continuation of swiotlb rework
	* Continuation of the refactor of core iommu code as part of SVA, iommufd, and pasid support work
	* Continuation of the iommufd prep work (config still not enabled)
	* Support for bounce buffer usage with non cache-line aligned kmallocs on arm64
	* Clean up of in-kernel pasid use for vt-d
	* More cleanup of BUG_ON and warning use in vt-d


        This is based on top of MR !2843 and !3158.
