Merge tag 'iommu-updates-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"This time there are not a lot of changes coming from the IOMMU side.
That is partly because I returned from my parental leave late in the
development process and probably partly because everyone was busy with
Spectre and Meltdown mitigation work and didn't find the time for
IOMMU work. So here are the few changes that queued up for this merge
window:
- 5-level page-table support for the Intel IOMMU.
- error reporting improvements for the AMD IOMMU driver
- additional DT bindings for ipmmu-vmsa (Renesas)
- small fixes and cleanups"
