Merge tag 'iommu-updates-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"The updates are mostly about the x86 IOMMUs this time.
Exceptions are the groundwork for the PAMU IOMMU from Freescale (for a
PPC platform) and an extension to the IOMMU group interface.
On the x86 side this includes a workaround for VT-d to disable
interrupt remapping on broken chipsets. On the AMD-Vi side the most
important new feature is a kernel command-line interface to override
broken information in IVRS ACPI tables and get interrupt remapping
working this way.
Besides that there are small fixes all over the place."
