[PATCH v4 16/22] iommu/vt-d: report non-recoverable faults to device

Currently, dmar fault IRQ handler does nothing more than rate limited printk, no critical hardware handling need to be done in IRQ context. For some use case such as vIOMMU, it might be useful to report non-recoverable faults outside host IOMMU subsystem. DMAR fault can come from both DMA and
