The patches fix several issues in the AMD IOMMU driver, the NVidia SMMU
driver, and the DMA debug code. The most important fix for the AMD IOMMU
solves a problem with SR-IOV devices where virtual functions did not
work with IOMMU enabled. The NVidia SMMU patch fixes a possible sleep
while spin-lock situation (queued the small fix for v3.5, a better but
more intrusive fix is coming for v3.6). The DMA debug patches fix a
possible data corruption issue due to bool vs. u32 usage.
