Subject: [git pull] IOMMU Updates for Linux v5.3
Hi Linus,
The following changes since commit 6fbc7275c7a9ba97877050335f290341a1fd8dbf:
Linux 5.2-rc7 (2019-06-30 11:25:36 +0800)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v5.3

Merge branches 'x86/vt-d', 'x86/amd', 'arm/smmu', 'arm/omap', 'generic-dma-ops' and 'core' into next (2019-07-04 17:26:48 +0200)
----------------------------------------------------------------
IOMMU Updates for Linux v5.3
Including:
- Patches to make the dma-iommu code more generic so that it can
be used outside of the ARM context with other IOMMU drivers.
Goal is to make use of it on x86 too.
- Generic IOMMU domain support for the Intel VT-d driver. This
driver now makes more use of common IOMMU code to allocate
default domains for the devices it handles.
- An IOMMU fault reporting API to userspace. With that the IOMMU
fault handling can be done in user-space, for example to
forward the faults to a VM.
- Better handling for reserved regions requested by the
firmware. These can be 'relaxed' now, meaning that those don't
prevent a device being attached to a VM.
- Suspend/Resume support for the Renesas IOMMU driver.
- Added support for dumping SVA related fields of the DMAR table
in the Intel VT-d driver via debugfs.
- A pile of smaller fixes and cleanups.
