This time the IOMMU updates are mostly cleanups or fixes. No big new
features or drivers this time. In particular the changes include:
* Bigger cleanup of the Domain<->IOMMU data structures and the
code that manages them in the Intel VT-d driver. This makes
the code easier to understand and maintain, and also easier to
keep the data structures in sync. It is also a preparation
step to make use of default domains from the IOMMU core in the
Intel VT-d driver.
* Fixes for a couple of DMA-API misuses in ARM IOMMU drivers,
namely in the ARM and Tegra SMMU drivers.
* Fix for a potential buffer overflow in the OMAP iommu driver's
debug code
* A couple of smaller fixes and cleanups in various drivers
* One small new feature: Report domain-id usage in the Intel
VT-d driver to easier detect bugs where these are leaked.
