Merge tag 'iommu-fixes-v3.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
"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."
