[PATCH] mm/hmm: replace hmm_update with mmu_notifier_range
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.

[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

[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

[RFC PATCH 00/13] SVM (share virtual memory) with HMM in nouveau
From: Jérôme Glisse <jglisse at redhat.com>
(mm is cced just to allow exposure of device driver work without ccing
a long list of peoples. I do not think there is anything usefull to
discuss from mm point of view but i might be wrong, so just for the
curious :)).

dev_pagemap related cleanups v4
Hi Dan, Jérôme and Jason,
below is a series that cleans up the dev_pagemap interface so that
it is more easily usable, which removes the need to wrap it in hmm
and thus allowing to kill a lot of code
Note: this series is on top of Linux 5.2-rc6 and has some minor
conflicts with the hmm tree that are easy to resolve.

[PATCH 0/4] HMM tests and minor fixes
These changes are based on Jason's latest hmm branch.
Patch 1 was previously posted here [1] but was dropped from the orginal
series. Hopefully, the tests will reduce concerns about edge conditions.
I'm sure more tests could be usefully added but I thought this was a good
starting point.
