[PATCH 0/2] Kill off pgsize_bitmap field from struct iommu_ops

Hi all,

These patches move the pgsize_bitmap field out of iommu_ops and into
the iommu_domain structure, as there are systems containing multiple
instances of a given IOMMU (e.g. the ARM SMMU) with different page size
support on the individual devices.

Once that's done, we can get back to treating the iommu_ops as constant,
since they just contain function pointers.

Comments welcome,

Will
