[PATCH v3 0/3] iommu/vt-d: Misc fixes on scalable mode

[Liu Yi L]

Hi Baolu, Joerg, Will,

This patchset aims to fix a bug regards to native SVM usage, and
also several bugs around subdevice (attached to device via auxiliary
manner) tracking and ineffective device_tlb flush.

v2 -> v3:
- Address comments from Baolu Lu against v2
- Rebased to 5.11-rc1
v2: https://lore.kernel.org/linux-iommu/20201223062720.29364-1-yi.l.liu@xxxxxxxxx/

v1 -> v2:
- Use a more recent Fix tag in "iommu/vt-d: Move intel_iommu info from struct intel_svm to struct intel_svm_dev"
- Refined the "iommu/vt-d: Track device aux-attach with subdevice_domain_info"
- Rename "iommu/vt-d: A fix to iommu_flush_dev_iotlb() for aux-domain" to be
  "iommu/vt-d: Fix ineffective devTLB invalidation for subdevices"
- Refined the commit messages
v1: https://lore.kernel.org/linux-iommu/20201220000352.183523-1-yi.l.liu@xxxxxxxxx/
