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 directly.

This is based on 5.3.0-rc1 plus Christoph Hellwig's 6 patches
("hmm_range_fault related fixes and legacy API removal v2").
Jason, I believe this is the patch you were requesting.
Doesn't this need revision to include amgpu?
drivers/gpu/drm/amd/amdgpu/amdgpu_mn.c: .sync_cpu_device_pagetables = amdgpu_mn_sync_pagetables_gfx,
drivers/gpu/drm/amd/amdgpu/amdgpu_mn.c: .sync_cpu_device_pagetables = amdgpu_mn_sync_pagetables_hsa,
Thanks,
Jason
Yes. I have added this to v2 which I'll send out with Christoph's 2
patches and the hmm_range.vma removal patch you suggested.
