IOMMU Updates for Linux v3.7-rc1 This time the IOMMU updates contain a bunch of fixes and cleanups to various IOMMU drivers and the DMA debug code. New features are the code for IRQ remapping support with the AMD IOMMU (preperation for that was already merged in the last release) and a debugfs interface to export some statistics in the NVidia Tegra IOMMU driver.
