Linus Torvalds a498d59c46 dma-mapping updates for Linux 6.18:
- refactoring of DMA mapping API to physical addresses as the primary
 interface instead of page+offset parameters; this gets much closer to
 Matthew Wilcox's long term wish for struct-pageless IO to cacheable DRAM and is
 supporting memdesc project which seeks to substantially transform how
 struct page works; an advantage of this approach is the possibility of
 introducing DMA_ATTR_MMIO, which covers existing 'dma_map_resource' flow
 in the common paths, what in turn lets to use recently introduced
 dma_iova_link() API to map PCI P2P MMIO without creating struct page;
 developped by Leon Romanovsky and Jason Gunthorpe
 - minor clean-up by Petr Tesarik and Qianfeng Rong
