Continue converting drivers to the new interface. Introduce
ops->blocked_domain to hold the global static BLOCKED domain and convert
all drivers supporting BLOCKED to use it.
This makes it trivial for dart and iommufd to convert over to
domain_alloc_paging().
There are six drivers remaining:
drivers/iommu/amd/iommu.c: .domain_alloc = amd_iommu_domain_alloc,
drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c: .domain_alloc =
arm_smmu_domain_alloc,
drivers/iommu/arm/arm-smmu/arm-smmu.c: .domain_alloc =
arm_smmu_domain_alloc,
drivers/iommu/fsl_pamu_domain.c: .domain_alloc = fsl_pamu_domain_alloc,
drivers/iommu/intel/iommu.c: .domain_alloc =
intel_iommu_domain_alloc,
drivers/iommu/virtio-iommu.c: .domain_alloc = viommu_domain_alloc,
The follows the "Make default_domain's mandatory" series
Jason Gunthorpe (8):
iommu: Move IOMMU_DOMAIN_BLOCKED global statics to ops->blocked_domain
iommu/vt-d: Update the definition of the blocking domain
iommu/vt-d: Use ops->blocked_domain
iommufd: Convert to alloc_domain_paging()
iommu/dart: Use static global identity domains
iommu/dart: Move the blocked domain support to a global static
iommu/dart: Convert to domain_alloc_paging()
iommu/dart: Call apple_dart_finalize_domain() as part of
alloc_paging()
