Merge tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull hmm updates from Jason Gunthorpe: "Ralph has been working on nouveau's use of hmm_range_fault() and migrate_vma() which resulted in this small series. It adds reporting of the page table order from hmm_range_fault() and some optimization of migrate_vma(): - Report the size of the page table mapping out of hmm_range_fault(). This makes it easier to establish a large/huge/etc mapping in the device's page table. - Allow devices to ignore the invalidations during migration in cases where the migration is not going to change pages. For instance migrating pages to a device does not require the device to invalidate pages already in the device. - Update nouveau and hmm_tests to use the above" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: mm/hmm/test: use the new migration invalidation nouveau/svm: use the new migration invalidation mm/notifier: add migration invalidation type mm/migrate: add a flags parameter to migrate_vma nouveau: fix storing invalid ptes nouveau/hmm: support mapping large sysmem pages nouveau: fix mapping 2MB sysmem pages nouveau/hmm: fault one page at a time mm/hmm: add tests for hmm_pfn_to_map_order() mm/hmm: provide the page mapping order in hmm_range_fault()
