Hi Linus,

The following changes since commit 64aa90f26c06e1cb2aacfb98a7d0eccfbd6c1a91:

IOMMU Updates for Linux v3.17

This time with:

* Support for the generic PCI device alias code in x86 IOMMU
drivers

* A new sysfs interface for IOMMUs

* Preparations for hotplug support in the Intel IOMMU driver

* Change the AMD IOMMUv2 driver to not hold references to core
data structures like mm_struct or task_struct. Rely on
mmu_notifers instead.

* Removal of the OMAP IOVMM interface, all users of it are
converted to DMA-API now

* Make the struct iommu_ops const everywhere

* Initial PCI support for the ARM SMMU driver

* There is now a generic device tree binding documented for
ARM IOMMUs

* Various fixes and cleanups all over the place

Also included are some changes to the OMAP code, which are acked by the
maintainer.
