Hi Linus,

this pull-request includes two reverts which I had to do after the merge
window started, because the reverted patches caused issues in
linux-next. But the rest of this was ready before the merge window. With
this in mind:

The following changes since commit 37624b58542fb9f2d9a70e6ea006ef8a5f66c30b:

  Linux 5.1-rc7 (2019-04-28 17:04:13 -0700)

are available in the Git repository at:

----------------------------------------------------------------
IOMMU Updates for Linux v5.2

Including:

	- ATS support for ARM-SMMU-v3.

	- AUX domain support in the IOMMU-API and the Intel VT-d driver.
	  This adds support for multiple DMA address spaces per
	  (PCI-)device. The use-case is to multiplex devices between
	  host and KVM guests in a more flexible way than supported by
	  SR-IOV.

	- The Rest are smaller cleanups and fixes, two of which needed
	  to be reverted after testing in linux-next.
