https://lore.kernel.org/linux-iommu/20231020135501.GG3952@nvidia.com/ The conversation above concluded that a hwpt should only enforce cache coherency per device at the stage of its allocation, and it should not be changed or updated in the attach/replace routines.
Add two patches dropping the enforce_cache_coherency calls from attach and replce routines respectively, since they were introduced with two different commits.
