Linus Torvalds 23022f5456 dma-mapping updates for Linux 6.16:
- new two step DMA mapping API, which is is a first step to a long path
   to provide alternatives to scatterlist and to remove hacks, abuses and
   design mistakes related to scatterlists; this new approach optimizes
   some calls to DMA-IOMMU layer and cache maintenance by batching them,
   reduces memory usage as it is no need to store mapped DMA addresses to
   unmap them, and reduces some function call overhead; it is a combination
   effort of many people, lead and developed by Christoph Hellwig and Leon
   Romanovsky
