Pull hmm updates from Jason Gunthorpe: "This is another round of bug fixing and cleanup. This time the focus is on the driver pattern to use mmu notifiers to monitor a VA range. This code is lifted out of many drivers and hmm_mirror directly into the mmu_notifier core and written using the best ideas from all the driver implementations. This removes many bugs from the drivers and has a very pleasing diffstat. More drivers can still be converted, but that is for another cycle. - A shared branch with RDMA reworking the RDMA ODP implementation - New mmu_interval_notifier API. This is focused on the use case of monitoring a VA and simplifies the process for drivers - A common seq-count locking scheme built into the mmu_interval_notifier API usable by drivers that call get_user_pages() or hmm_range_fault() with the VA range - Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen GntDev drivers to the new API. This deletes a lot of wonky driver code. - Two improvements for hmm_range_fault(), from testing done by Ralph" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: mm/hmm: remove hmm_range_dma_map and hmm_range_dma_unmap mm/hmm: make full use of walk_page_range() xen/gntdev: use mmu_interval_notifier_insert mm/hmm: remove hmm_mirror and related drm/amdgpu: Use mmu_interval_notifier instead of hmm_mirror drm/amdgpu: Use mmu_interval_insert instead of hmm_mirror drm/amdgpu: Call find_vma under mmap_sem nouveau: use mmu_interval_notifier instead of hmm_mirror nouveau: use mmu_notifier directly for invalidate_range_start drm/radeon: use mmu_interval_notifier_insert RDMA/hfi1: Use mmu_interval_notifier_insert for user_exp_rcv RDMA/odp: Use mmu_interval_notifier_insert() mm/hmm: define the pre-processor related parts of hmm.h even if disabled mm/hmm: allow hmm_range to be used with a mmu_interval_notifier or hmm_mirror mm/mmu_notifier: add an interval tree notifier mm/mmu_notifier: define the header pre-processor parts even if disabled mm/hmm: allow snapshot of the special zero page

drm/amdgpu: Use mmu_interval_notifier instead of hmm_mirror

2019-11-23T23:56:45Z

Convert the collision-retry lock around hmm_range_fault to use the one now provided by the mmu_interval notifier. Although this driver does not seem to use the collision retry lock that hmm provides correctly, it can still be converted over to use the mmu_interval_notifier api instead of hmm_mirror without too much trouble. This also deletes another place where a driver is associating additional data (struct amdgpu_mn) with a mmu_struct.

drm/amdgpu: user pages array memory leak fix

2019-10-17T21:12:34Z

user_pages array should always be freed after validation regardless if user pages are changed after bo is created because with HMM change parse bo always allocate user pages array to get user pages for userptr bo. v2: remove unused local variable and amend commit v3: add back get user pages in gem_userptr_ioctl, to detect application bug where an userptr VMA is not ananymous memory and reject it.
