Subject: [PATCH v2 0/2] iommu/vt-d: Some misc tweaks in SVA

This includes some misc tweaks in the VT-d SVA implementation. I will
plan them for v5.12 if no objections.

Change log:
v1->v2:
  - v1:
    https://lore.kernel.org/linux-iommu/20210121014505.1659166-1-baolu.lu@linux.intel.com/
  - Keep the logic of clearing PRO sane
  - Drop the device outstanding PRQ number patch. Need more test and
    will repost later. 

Best regards,
baolu

Lu Baolu (2):
  iommu/vt-d: Clear PRQ overflow only when PRQ is empty
  iommu/vt-d: Use INVALID response code instead of FAILURE
