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)
