This depends on some other changes, and is being marked as a fix because it removes something no longer needed once the other code is in place. I need to look at the other changes, but if they are going in, they will go in a separate MR.

Summary of Changes

Recent fixes that have landed upstream that touch drivers we support in the IOMMU, and DMAEngine subsystems, including:

  • Some fixes for dumping io page table info when a DMAR fault occurs for Intel.
  • Locking fix for AMD v2 page table invalidation.
  • Fix missed allocation for nested domains in qi batching code which could lead to null pointer dereference.
  • Defer client probing in arm-smmu to avoid of_dma_configure being called prior to driver_bound resulting in null pointer dereference.
  • Implement blocking domain for s390.
  • dmaengine tegra: return correct status when paused.
  • dmaengine dw: select only supported masters for acpi devices.
