Merge tag 'iommu-fixes-5.4-rc1' of git://git.kernel.org/pub/scm/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"
