RE: [PATCH 07/14] iommufd: Add enforced_cache_coherency to iommufd_hw_pagetable_alloc()

From: Jason Gunthorpe jgg@nvidia.com Sent: Saturday, February 25, 2023 8:28 AM

Logically the HWPT should have the coherency set properly for the device that it is being created for when it is created.

This was happening implicitly if the immediate_attach was set because iommufd_hw_pagetable_attach() does it as the first thing.

Do it unconditionally so !immediate_attach works properly.
