IOMMU Updates for Linux 3.5

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.
