[PATCH v2 00/15] Consolidate the mmu notifier interval_tree and locking
From: Jason Gunthorpe <jgg at mellanox.com>
8 of the mmu_notifier using drivers (i915_gem, radeon_mn, umem_odp, hfi1,
scif_dma, vhost, gntdev, hmm) drivers are using a common pattern where
they only use invalidate_range_start/end and immediately check the
invalidating range against some driver data structure to tell if the
driver is interested. Half of them use an interval_tree, the others

[PATCH v2 0/7] mm/hmm: more HMM clean up
Here are seven more patches for things I found to clean up.
This was based on top of Christoph's seven patches:
"hmm_range_fault related fixes and legacy API removal v3".
I assume this will go into Jason's tree since there will likely be
more HMM changes in this cycle.
Changes from v1 to v2:
Added AMD GPU to hmm_update removal.
Added 2 patches from Christoph.
Added 2 patches as
