Hi,

This patch set contains various code cleanup and bug fix: init.patch: Since device id covered by each iommu can never overlap, use a global device table instead of allocating private tables for each iommu. Migrate a few functions from pci_amd_iommu.c acpi.patch: Remove device range register access, parse acpi structures to acquire IO topology. detect.patch: Remove pci scanning, parse acpi structures to detect iommu hardware. intr.patch: Add deallocation for interrupt remapping table. misc.patch: Miscellaneous changes to accommodate above modifications.

Thanks, -Wei
