Linus Torvalds 726e2d0cf2 dma-mapping updates for linux 6.12
- support DMA zones for arm64 systems where memory starts at > 4GB
    (Baruch Siach, Catalin Marinas)
  - support direct calls into dma-iommu and thus obsolete dma_map_ops for
    many common configurations (Leon Romanovsky)
  - add DMA-API tracing (Sean Anderson)
  - remove the not very useful return value from various dma_set_* APIs
    (Christoph Hellwig)
  - misc cleanups and minor optimizations (Chen Y, Yosry Ahmed,
    Christoph Hellwig)

* tag 'dma-mapping-6.12-2024-09-19' of git://git.infradead.org/users/hch/dma-mapping:
  dma-mapping: reflow dma_supported
  dma-mapping: reliably inform about DMA support for IOMMU
  dma-mapping: add tracing for dma-mapping API calls
  dma-mapping: use IOMMU DMA calls for common alloc/free page calls
  dma-direct: optimize page freeing when it is not addressable
  dma-mapping: clearly mark DMA ops as an architecture feature
  vdpa_sim: don't select DMA_OPS
  arm64: mm: keep low RAM dma zone
  dma-mapping: don't return errors from dma_set_max_seg_size
  dma-mapping: don't return errors from dma_set_seg_boundary
  dma-mapping: don't return errors from dma_set_min_align_mask
  scsi: check that busses support the DMA API before setting dma parameters
  arm64: mm: fix DMA zone when dma-ranges is missing
  dma-mapping: direct calls for dma-iommu
  dma-mapping: call ->unmap_page and ->unmap_sg unconditionally
  arm64: support DMA zone above 4GB
  dma-mapping: replace zone_dma_bits by zone_dma_limit
