stion: shall we add PASID as one parameter to make iommu
know which address space to visit?
For live migration, the pasid should not be necessary. But considering
future extension, it may be required.

unsigned long iova, size_t size,

Same comments to patch 5.

Should get correct sid and set it into sdev. Because we execute
'sdev->sid != req->rid' in the loop of prq_event_thread().

In prq_event_thread(), the QI_PGRP_PDP is wrongly set by
'req->pasid_present' which should be replaced to
'req->priv_data_present'.
Fixes: 5b438f4ba315 ("iommu/vt-d: Support page request in scalable mode")

We found a few issues about PRQ. So, two patches are cooked to
fix them. Please have a review. Thanks!
Changes from v1:
- Modify subject of patch 1 to make it more accurate.
- Move get_domain_info() up to the sanity check part in patch 1.
- Remove v1 patch 2 which is not suitable.
