Merge tag 'iommu-updates-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull iommu updates for from Joerg Roedel:
 "This time the IOMMU updates are mostly cleanups or fixes.  No big new
  features or drivers this time.  In particular the changes include:

   - Bigger cleanup of the Domain<->IOMMU data structures and the code
     that manages them in the Intel VT-d driver.  This makes the code
     easier to understand and maintain, and also easier to keep the data
     structures in sync.  It is also a preparation step to make use of
     default domains from the IOMMU core in the Intel VT-d driver.

   - Fixes for a couple of DMA-API misuses in ARM IOMMU drivers, namely
     in the ARM and Tegra SMMU drivers.

   - Fix for a potential buffer overflow in the OMAP iommu driver's
     debug code

   - A couple of smaller fixes and cleanups in various drivers

   - One small new feature: Report domain-id usage in the Intel VT-d
     driver to easier detect bugs where these are leaked"
