Lu Baolu be9e6598ae iommu/vt-d: Handle memory shortage on pasid table allocation ... Pasid table memory allocation could return failure due to memory shortage. Limit the pasid table size to 1MiB because current 8MiB contiguous physical memory allocation can be hard to come by. W/o a PASID table, the device could continue to work with only shared virtual memory impacted. So, let's go ahead with context mapping even the memory allocation for pasid table failed.
