Hi,

This collects a number of pre-existing issues that were reported by
Sashiko while reviewing recent VT-d patches. None of them are
regressions from the patches under review; they are latent problems in
code those patches happened to touch. They are independent of each other
and can be applied in any order.

Thanks,
baolu

Lu Baolu (5):
  iommu/vt-d: Fix shift overflow in qi_desc_dev_iotlb_pasid()
  iommu/vt-d: Clear Present bit before tearing down copied context entry
  iommu/vt-d: Fix iopf_refcount leak on RID domain replacement
  iommu/vt-d: Tear down scalable-mode context on probe failure
  iommu/vt-d: Flush context cache with correct SID when tearing down
    aliases

Queued for iommu/vt-d.
