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"
