Zenghui Yu a7cefaccca iommu/vt-d: Fix status code for Allocate/Free PASID command ... [ Upstream commit 444d66a23c1f1e4c4d12aed4812681d0ad835d60 ] As per Intel vt-d spec, Rev 3.0 (section 10.4.45 "Virtual Command Response Register"), the status code of "No PASID available" error in response to the Allocate PASID command is 2, not 1. The same for "Invalid PASID" error in response to the Free PASID command. We will otherwise see confusing kernel log under the command failure from guest side. Fix it.
