Subject: [PATCH 0/7] [PULL REQUEST] Intel IOMMU updates for v6.20

Hi Joerg,

The following changes have been queued for v6.20-rc1. They are about
some non-critical fixes, including:

 - Skip dev-iotlb flush for inaccessible PCIe device
 - Flush cache for PASID table before using it
 - Use right invalidation method for SVA and NESTED domains
 - Ensure atomicity in context and PASID entry updates

These patches are based on v6.19-rc6. Please consider them for the
iommu/vt-d branch.

Best regards,
baolu

  iommu/vt-d: Flush cache for PASID table before using it

Jinhui Guo (2):
  iommu/vt-d: Skip dev-iotlb flush for inaccessible PCIe device without
    scalable mode
  iommu/vt-d: Flush dev-IOTLB only when PCIe device is accessible in
    scalable mode

Lu Baolu (3):
  iommu/vt-d: Clear Present bit before tearing down PASID entry
  iommu/vt-d: Clear Present bit before tearing down context entry
  iommu/vt-d: Fix race condition during PASID entry replacement
