Add iommu fault report mechanism to the IOMMU API, so implementations could report about mmu faults (translation errors, hardware errors, etc..). Fault reports can be used in several ways: - mere logging - reset the device that accessed the faulting address (may be necessary in case the device is a remote processor for example) - implement dynamic PTE/TLB loading A dedicated iommu_set_fault_handler() API has been added to allow users, who are interested to receive such reports, to provide their handler.
