Subject[git pull] IOMMU Updates for Linux v4.12
Hi Linus,

The following changes since commit 5a7ad1146caa895ad718a534399e38bd2ba721b7:

Linux 4.11-rc8 (2017-04-23 16:53:00 -0700)

are available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v4.12

for you to fetch changes up to 2c0248d68880fc0e783af1048b3367ee5d4412f0:

Merge branches 'arm/exynos', 'arm/omap', 'arm/rockchip', 'arm/mediatek', 'arm/smmu', 'arm/core', 'x86/vt-d', 'x86/amd' and 'core' into next (2017-05-04 18:06:17 +0200)

----------------------------------------------------------------
IOMMU Updates for Linux v4.12

This includes:

* Some code optimizations for the Intel VT-d driver

* Code to switch off a previously enabled Intel IOMMU

* Support for 'struct iommu_device' for OMAP, Rockchip and
Mediatek IOMMUs

* Some header optimizations for IOMMU core code headers and a
few fixes that became necessary in other parts of the kernel
because of that

* ACPI/IORT updates and fixes

* Some Exynos IOMMU optimizations

* Code updates for the IOMMU dma-api code to bring it closer to
use per-cpu iova caches

* New command-line option to set default domain type allocated
by the iommu core code

* Another command line option to allow the Intel IOMMU switched
off in a tboot environment

* ARM/SMMU: TLB sync optimisations for SMMUv2, Support for using
an IDENTITY domain in conjunction with DMA ops, Support for
SMR masking, Support for 16-bit ASIDs (was previously broken)

* Various other small fixes and improvements
