Merge tag 'iommu-fixes-5.4-rc1' of git://git./linux/kernel/git/joro/iommu

Pull iommu fixes from Joerg Roedel:
 "A couple of fixes for the AMD IOMMU driver have piled up:

   - Some fixes for the reworked IO page-table which caused memory leaks
     or did not allow to downgrade mappings under some conditions.

   - Locking fixes to fix a couple of possible races around accessing
     'struct protection_domain'. The races got introduced when the
     dma-ops path became lock-less in the fast-path"
