v2 for internal review - heavily reworked NET_F_MAC patch, matches recent PR-68875 - reordered to put "clean and reset vqs" before "alloc-irq" to make them slightly simpler patches - other minor cleanups for simpler patches These are some fixes for device providing a MAC address, for allocating irq resources later to support vhost use, and for properly cleaning vq info

Hi, here is the third version of this patch-set. Older versions can be found here: v1: https://lore.kernel.org/lkml/20200407183742.4344-1-joro at 8bytes.org/ (Has some more introductory text) v2: https://lore.kernel.org/lkml/20200414131542.25608-1-joro at 8bytes.org/ Changes v2 -> v3: * Rebased v5.7-rc3 * Added a missing iommu_group_put() as reported by Lu Baolu. * Added a

Hi, here is a patch-set to remove all calls of iommu_group_get_for_dev() from the IOMMU drivers and move the per-device group setup and default domain allocation into the IOMMU core code. This eliminates some ugly back and forth between IOMMU core code and the IOMMU drivers, where the driver called iommu_group_get_for_dev() which itself called back into the driver. The patch-set started as a

This series adds support for transparent huge page migration to migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers. Earlier versions were posted previously [1] and [2]. The patches apply cleanly to the linux-mm 5.10.0-rc2 tree. There are a lot of other THP patches being posted. I don't think there are any semantic conflicts but there may be some merge conflicts depending on

This series adds support for transparent huge page migration to migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers. An earlier version was posted previously [1]. This version now supports splitting a THP midway in the migration process which led to a number of changes. The patches apply cleanly to the current linux-mm tree. Since there are a couple of patches in linux-mm from Dan
