IOMMU Updates for Linux 3.5

Browse source 
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.
