Good catch, thanks!
After applying 14cebf689a78 ("swiotlb: Reinstate> page-alignment for
mappings >= PAGE_SIZE")
on top of 6.6.33 I no longer have the flood of alignment warnings and
iwlwifi can be used again:

Will, is it OK for me to ask the stable folks to backport 14cebf689a78
("swiotlb: Reinstate> page-alignment for mappings >= PAGE_SIZE")
to 6.6 stable?
Thanks!
