#     
#     Pull iommu fixes from Joerg Roedel:
#     
#      - Fix a device reference counting bug in the Exynos IOMMU driver.
#     
#      - Lockdep fix for the Intel VT-d driver.
#     
#      - Fix a bug in the AMD IOMMU driver which caused corruption of the IVRS
#        ACPI table and caused IOMMU driver initialization failures in kdump
#        kernels.
