Linus Torvalds 6c1b980a7e dma-maping updates for Linux 6.6
- allow dynamic sizing of the swiotlb buffer, to cater for secure
    virtualization workloads that require all I/O to be bounce buffered
    (Petr Tesarik)
  - move a declaration to a header (Arnd Bergmann)
  - check for memory region overlap in dma-contiguous (Binglei Wang)
  - remove the somewhat dangerous runtime swiotlb-xen enablement and
    unexport is_swiotlb_active (Christoph Hellwig, Juergen Gross)
  - per-node CMA improvements (Yajun Deng)
