Merge git://git.infradead.org/iommu-2.6
* git://git.infradead.org/iommu-2.6: intel-iommu: Set a more specific taint flag for invalid BIOS DMAR tables intel-iommu: Combine the BIOS DMAR table warning messages panic: Add taint flag TAINT_FIRMWARE_WORKAROUND ('I') 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.
