[PATCH 0/2] iommu/amd: Honor IVINFO[PAsize] for paging domains

[Ankit Soni]

The AMD IOMMU driver hardcodes a 52-bit output address size when it
creates paging domains. This series honors the PAsize reported in ACPI
IVRS IVinfo instead, so maps cannot exceed what firmware or a VM
advertises. Patch 1 moves page-table setup into init_pgtable_params()
after the IVHD walk, with no functional change intended. Patch 2 uses that
helper for PAsize and applies it to paging domains.

Ankit Soni (2):
  iommu/amd: Move page-table setup into init_pgtable_params()
  iommu/amd: Adhere to IVINFO[PAsize] for output address limits
