Pull hmm updates from Jason Gunthorpe: "This is more cleanup and consolidation of the hmm APIs and the very strongly related mmu_notifier interfaces. Many places across the tree using these interfaces are touched in the process. Beyond that a cleanup to the page walker API and a few memremap related changes round out the series: - General improvement of hmm_range_fault() and related APIs, more documentation, bug fixes from testing, API simplification & consolidation, and unused API removal - Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and make them internal kconfig selects - Hoist a lot of code related to mmu notifier attachment out of drivers by using a refcount get/put attachment idiom and remove the convoluted mmu_notifier_unregister_no_release() and related APIs. - General API improvement for the migrate_vma API and revision of its only user in nouveau - Annotate mmu_notifiers with lockdep and sleeping region debugging Two series unrelated to HMM or mmu_notifiers came along due to dependencies: - Allow pagemap's memremap_pages family of APIs to work without providing a struct device - Make walk_page_range() and related use a constant structure for function pointers" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (75 commits) libnvdimm: Enable unit test infrastructure compile checks mm, notifier: Catch sleeping/blocking for !blockable kernel.h: Add non_block_start/end() drm/radeon: guard against calling an unpaired radeon_mn_unregister() csky: add missing brackets in a macro for tlb.h pagewalk: use lockdep_assert_held for locking validation pagewalk: separate function pointers from iterator data mm: split out a new pagewalk.h header from mm.h mm/mmu_notifiers: annotate with might_sleep() mm/mmu_notifiers: prime lockdep mm/mmu_notifiers: add a lockdep map for invalidate_range_start/end mm/mmu_notifiers: remove the __mmu_notifier_invalidate_range_start/end exports mm/hmm: hmm_range_fault() infinite loop mm/hmm: hmm_range_fault() NULL pointer bug mm/hmm: fix hmm_range_fault()'s handling of swapped out pages mm/mmu_notifiers: remove unregister_no_release RDMA/odp: remove ib_ucontext from ib_umem RDMA/odp: use mmu_notifier_get/put for 'struct ib_ucontext_per_mm' RDMA/mlx5: Use odp instead of mr->umem in pagefault_mr RDMA/mlx5: Use ib_umem_start instead of umem.address ...

amdgpu: don't initialize range->list in amdgpu_hmm_init_range

2019-08-07T17:51:46Z

The list is used to add the range to another list as an entry in the core hmm code, and intended as a private member not exposed to drivers. There is no need to initialize it in a driver.

mm/hmm: replace hmm_update with mmu_notifier_range

2019-07-26T14:10:53Z

The hmm_mirror_ops callback function sync_cpu_device_pagetables() passes a struct hmm_update which is a simplified version of struct mmu_notifier_range. This is unnecessary so replace hmm_update with mmu_notifier_range directly.

drm/amdgpu: Prepare for hmm_range_register API change (v2)

2019-07-08T18:55:00Z

An upcoming change in the hmm_range_register API requires passing in a pointer to an hmm_mirror instead of mm_struct. To access the hmm_mirror we need pass bo instead of ttm to amdgpu_ttm_tt_get_user_pages because mirror is part of amdgpu_mn structure, which is accessible from bo. v2: fix building without CONFIG_HMM_MIRROR (Arnd) Signed-off-by: Philip Yang Signed-off-by: Felix Kuehling Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: use new HMM APIs and helpers

2019-06-11T17:56:01Z

HMM provides new APIs and helps in kernel 5.2-rc1 to simplify driver path. The old hmm APIs are deprecated and will be removed in future. Below are changes in driver: 1. Change hmm_vma_fault to hmm_range_register and hmm_range_fault which supports range with multiple vmas, remove the multiple vmas handle path and data structure. 2. Change hmm_vma_range_done to hmm_range_unregister. 3. Use default flags to avoid pre-fill pfn arrays. 4. Use new hmm_device_ helpers.
