This series renames pmd_mknotpresent() as pmd_mknotvalid(). Before that it drops an existing pmd_mknotpresent() definition from powerpc platform which was never required as it defines it's pmdp_invalidate() through subscribing __HAVE_ARCH_PMDP_INVALIDATE. This does not create any functional change. This rename was suggested by Catalin during a previous discussion while we were trying to change the THP helpers on arm64 platform for migration. https://patchwork.kernel.org/patch/11019637/ This serie...

These patches apply to linux-5.8.0-rc1. Patches 1-3 should probably go into 5.8, the others can be queued for 5.9. Patches 4-6 improve the HMM self tests. Patch 7-8 prepare nouveau for the meat of this series which adds support and testing for compound page mapping of system memory (patches 9-11) and compound page migration to device private memory (patches 12-16). Since these changes are split

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
