Thanks for the suggestion.

>From this series, only the two patches below are not present in the
6.6 stable tree:

swiotlb: Enforce page alignment in swiotlb_alloc()
swiotlb: Reinstate page-alignment for mappings >= PAGE_SIZE

I will submit these two to stable and also an additional one:

swiotlb: extend buffer pre-padding to alloc_align_mask if necessary

Thanks,
