  panic: Allow warnings to set different taint flags
  intel-iommu: intel_iommu_map_range failed at very end of address space
  intel-iommu: errors with smaller iommu widths
  intel-iommu: Fix boot inside 64bit virtualbox with io-apic disabled
  intel-iommu: use physfn to search drhd for VF
  intel-iommu: Print out iommu seq_id
  intel-iommu: Don't complain that ACPI_DMAR_SCOPE_TYPE_IOAPIC is not supported
  intel-iommu: Avoid global flushes with caching mode.
  intel-iommu: Use correct domain ID when caching mode is enabled
  intel-iommu mistakenly uses offset_pfn when caching mode is enabled
  intel-iommu: use for_each_set_bit()
  intel-iommu: Fix section mismatch dmar_ir_support() uses dmar_tbl.
