iommu/amd: Lock code paths traversing protection_domain->dev_list (2019-09-28

----------------------------------------------------------------
IOMMU Fixes for Linux v5.4-rc1
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.

Andrei Dulea (4):
iommu/amd: Fix pages leak in free_pagetable()
iommu/amd: Fix downgrading default page-sizes in alloc_pte()
iommu/amd: Introduce first_pte_l7() helper
iommu/amd: Unmap all L7 PTEs when downgrading page-sizes
Filippo Sironi (1):
iommu/amd: Wait for completion of IOTLB flush in attach_device
Joerg Roedel (6):
iommu/amd: Remove domain->updated
iommu/amd: Remove amd_iommu_devtable_lock
iommu/amd: Take domain->lock for complete attach/detach path
iommu/amd: Check for busy devices earlier in attach_device()
iommu/amd: Lock dev_data in attach/detach code paths
iommu/amd: Lock code paths traversing protection_domain->dev_list
