Linus Torvalds 87768582a4 dma-mapping updates for Linux 7.0:
- added support for batched cache sync, what improves performance of
   dma_map/unmap_sg() operations on ARM64 architecture (Barry Song)
 
 - introduced DMA_ATTR_CC_SHARED attribute for explicitly shared memory
   used in confidential computing (Jiri Pirko)
 
 - refactored spaghetti-like code in drivers/of/of_reserved_mem.c and its
   clients (Marek Szyprowski, shared branch with device-tree updates to
   avoid merge conflicts)
 
 - prepared Contiguous Memory Allocator related code for making dma-buf
   drivers modularized (Maxime Ripard)
 
 - added support for benchmarking dma_map_sg() calls to tools/dma utility
