Subject: [PATCH v2 0/8] iommu/vt-d: Some cleanups

Hi,

This series includes some cleanups in the Intel IOMMU implementation
after the IOMMU core implemented the blocking domain. The cleanup work
is mainly in the attach_dev/device_probe/device_release paths.

Please help to review.

Best regards,
baolu

Change log:
v2:
 - Reorder the patches to make the device_block_translation() work with
   the existing path first.
 - Add a new patch to improve iommu_enable_pci_caps().

v1:
 - https://lore.kernel.org/linux-iommu/20221103055329.633052-1-baolu.lu@linux.intel.com/

Lu Baolu (8):
  iommu/vt-d: Allocate pasid table in device probe path
  iommu/vt-d: Improve iommu_enable_pci_caps()
  iommu/vt-d: Add device_block_translation() helper
  iommu/vt-d: Add blocking domain support
  iommu/vt-d: Fold dmar_remove_one_dev_info() into its caller
  iommu/vt-d: Rename domain_add_dev_info()
  iommu/vt-d: Remove unnecessary domain_context_mapped()
  iommu/vt-d: Use real field for indication of first level
