intel-iommu: Check for an RMRR which ends before it starts.
intel-iommu: Apply BIOS sanity checks for interrupt remapping too.
intel-iommu: Detect DMAR in hyperspace at probe time.
dmar: Fix build failure without NUMA, warn on bogus RHSA tables and don't abort
iommu: Allocate dma-remapping structures using numa locality info
intr_remap: Allocate intr-remapping table using numa locality info
