[PATCH v6 0/6] mm/hmm/test: add self tests for HMM
This series adds new functions to the mmu interval notifier API to
allow device drivers with MMUs to dynamically mirror a process' page
tables based on device faults and invalidation callbacks. The Nouveau
driver is updated to use the extended API and a set of stand alone self
tests is added to help validate and maintain correctness.
The patches are based on linux-5.5.0-rc6 and are for

[PATCH hmm v3 00/14] 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
