From cf39047e460e86c4bc060e219f7cf4142eadf97e Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 9 Jun 2025 17:41:28 -0300 Subject: iommu: Remove iommu_ops pgsize_bitmap from simple drivers These drivers just have a constant value for their page size, move it into their domain_alloc_paging function before setting up the geometry.
