Hi all,

This series of patches are some small fixes for tegra-smmu, mainly
tested Tegra210 with downstream kernel. As we only enabled limited
clients for Tegra210 on mainline tree, I am not sure how critical
these fixes are, so not CCing stable tree.

Nicolin Chen (4):
  memory: tegra: Correct reset value of xusb_hostr
  iommu/tegra-smmu: Do not use PAGE_SHIFT and PAGE_MASK
  iommu/tegra-smmu: Fix iova->phy translation
  iommu/tegra-smmu: Prevent race condition between map and unmap
