Subject: [PATCH v2 00/17] [PULL REQUEST] Intel IOMMU updates for Linux v6.4

Hi Joerg,

This includes patches queued for v6.4. They are:

 - Allow the VT-d driver to support non-PRI IOPF
 - Remove PASID supervisor request support
 - Various small and misc cleanups

This series also includes an idxd patch to avoid driver regression after
changes in the IOMMU driver. It has been reviewed and acked by the
maintainers.

The whole series is based on v6.3-rc6 and also available at:
https://github.com/LuBaolu/intel-iommu/commits/vtd-update-for-v6.4

Please pull them for x86/vt-d branch.

Best regards,
Baolu

Change log:
 - v2:
   - Avoid using "fix" wording in the commit message of a cleanup patch,
