Nice callchain from hell.. Unfortunately such "code listings" tend to
get out of date very quickly, so I'm not sure it is worth keeping in
the code. What would be really worthile is consolidating the two
different sets of defines (NVIF_VMM_PFNMAP_V0_ vs NVKM_VMM_PFN_)
to make the code a little easier to follow.

I was mainly concerned that this function is using hmm properly,
becuase it sure looks like it is just forming the CPU physical address
into a HW specifi...

[PATCH hmm 0/5] Adjust hmm_range_fault() API
From: Jason Gunthorpe <jgg at mellanox.com>
The API is a bit complicated for the uses we actually have, and
disucssions for simplifying have come up a number of times.
This small series removes the customizable pfn format and simplifies the
return code of hmm_range_fault()
All the drivers are adjusted to process in the simplified format.
I would appreciated tested-by's for the two
