Merge tag 'iommu-updates-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"Not much stuff this time. The only change to the IOMMU core code is
the addition of a handle to the fault handling code. A few updates to
the AMD IOMMU driver to work around new errata. The other patches are
mostly fixes and enhancements to the existing ARM IOMMU drivers and
documentation updates.
A new IOMMU driver for the Exynos platform was also underway but got
merged via the Samsung tree and is not part of this tree."
