On that note, I've just updated my next branch[1] to include the
patches below.  This is Joerg's last merge to his next branch:

a593472591a5 Merge branches 'iommu/fixes', 'arm/omap', 'arm/exynos', 'x86/amd', 'x86/vt-d' and 'core' into next

Will's pull request:

18b0f1ccdb82 Merge branch 'for-joerg/arm-smmu/updates' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into iommu/arm/smmu

Plus a few iommu and vfio patches that I've pulled from the list since
those.  I'm making more of an effort to use branches than I do for just
vfio such that I can keep things separated for Joerg's return and
provide separate pull requests to Linus for vfio and iommu with a
minimum of sha1 breakage.  I'd ask the other sub-maintainers and
contributors to be extra proactive in providing reviews and pointing
out patches that I'm missing while Joerg is away.  I appreciate any
help in making this as smooth as possible for everyone.  Thanks,

Alex
