[PATCH 00/14] Minor fixups and refactorings for AMD's io-pgtable code

[Jason Gunthorpe <jgg@nvidia.com>]

This is some preparation for the Generic PT work here:

 https://patch.msgid.link/r/0-v1-01fa10580981+1d-iommu_pt_jgg@nvidia.com

Where this aims to increase the separation between the page table code and
the rest of the driver. Ideally the io_pgtable layer should be completely
self contained and not reach out into the IOMMU driver's
iommu_domain. This doesn't fully get there, but it does enough for now.

Jason Gunthorpe (14):
  iommu/amd: Move allocation of the top table into v1_alloc_pgtable
  iommu/amd: Allocate the page table root using GFP_KERNEL
  iommu/amd: Set the pgsize_bitmap correctly
  iommu/amd: Remove amd_iommu_domain_update() from page table freeing
  iommu/amd: Remove the amd_iommu_domain_set_pt_root() and related
  iommu/amd: Rename struct amd_io_pgtable iopt to pgtbl
  iommu/amd: Remove amd_io_pgtable::pgtbl_cfg
  iommu/amd: Store the nid in io_pgtable_cfg instead of the domain
  iommu/amd: Narrow the use of struct protection_domain to invalidation
  iommu/amd: Remove conditions from domain free paths
  iommu/amd: Fix typo of , instead of ;
  iommu/amd: Remove the confusing dummy iommu_flush_ops tlb ops
  iommu/amd: Correct the reported page sizes from the V1 table
  iommu/amd: Do not set the D bit on AMD v2 table entries
