Lu Baolu add43c4fbc iommu/vt-d: Make intel_iommu_drain_pasid_prq() cover faults for RID ... This driver supports page faults on PCI RID since commit <9f831c16c69e> ("iommu/vt-d: Remove the pasid present check in prq_event_thread") by allowing the reporting of page faults with the pasid_present field cleared to the upper layer for further handling. The fundamental assumption here is that the detach or replace operations act as a fence for page faults. This implies that all pending page faults associated with a specific RID or PASID are flushed when a domain is detached or replaced from a device RID or PASID. However, the intel_iommu_drain_pasid_prq() helper does not correctly handle faults for RID. This leads to faults potentially remaining pending in the iommu hardware queue even after the domain is detached, thereby violating the aforementioned assumption. Fix this issue by extending intel_iommu_drain_pasid_prq() to cover faults for RID.
