We have three cases to handle:
- EVENT_FLAG_I set: IRQ remapping fault, don't call report_iommu_fault()

This patch makes iommu/amd call report_iommu_fault() when an I/O page

1) It allows device drivers to register a callback to be notified of
I/O page faults, via the iommu_set_fault_handler() API.
This patch makes iommu/amd call report_iommu_fault() when an I/O page
fault occurs, which has two effects:
1) It allows device drivers to register a callback to be notified of
I/O page faults, via the iommu_set_fault_handler() API.
2) It triggers the io_page_fault tracepoint in
