Merge branch 'for-next/svm' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux into for-joerg/arm-smmu/updates

Browse source

Pull in core arm64 changes required to enable Shared Virtual Memory
(SVM) using SMMUv3. This brings us increasingly closer to being able to
share page-tables directly between user-space tasks running on the CPU
and their corresponding contexts on coherent devices performing DMA
through the SMMU.
