Subject: [PATCH 00/25] [PULL REQUEST] Intel IOMMU updates for Linux v5.20

Hi Joerg,

This includes patches queued for v5.20. It includes:

 - Make intel-iommu.h private
 - Optimize the use of two locks
 - Extend the driver to support large-scale platforms
 - Cleanup some dead code

The whole series is also available at:
https://github.com/LuBaolu/intel-iommu/commits/vtd-update-for-v5.20

Please consider them for v5.20.

[The vt-d branch needs to include below fix patch:
 4140d77a02210 ("iommu/vt-d: Fix RID2PASID setup/teardown failure")
 before applying the patches.]

Best regards,
Baolu
