----------------------------------------------------------------
dma-mapping fixes for Linux 6.9

This has a set of swiotlb alignment fixes for sometimes very long
standing bugs from Will.  We've been discussion them for a while and they
should be solid now.

----------------------------------------------------------------
Nicolin Chen (1):
      iommu/dma: Force swiotlb_max_mapping_size on an untrusted device

Will Deacon (5):
      swiotlb: Fix double-allocation of slots due to broken alignment handling
      swiotlb: Enforce page alignment in swiotlb_alloc()
      swiotlb: Honour dma_alloc_coherent() alignment in swiotlb_alloc()
      swiotlb: Fix alignment checks when both allocation and DMA masks are present
      swiotlb: Reinstate page-alignment for mappings >= PAGE_SIZE
