This series focuses on corner case bug fixes and general clarity
improvements to hmm_range_fault().
- 9 bug fixes
- Allow pgmap to track the 'owner' of a DEVICE_PRIVATE - in this case the
owner tells the driver if it can understand the DEVICE_PRIVATE page or
not. Use this to resolve a bug in nouveau where it could touch
DEVICE_PRIVATE pages from other drivers.
- Remove a bunch of dead, redundant or unused code and flags
- Clarity improvements to hmm_range_fault()

Pull hmm updates from Jason Gunthorpe:
"This series focuses on corner case bug fixes and general clarity
improvements to hmm_range_fault(). It arose from a review of
hmm_range_fault() by Christoph, Ralph and myself.
hmm_range_fault() is being used by these 'SVM' style drivers to
non-destructively read the page tables. It is very similar to
get_user_pages() except that the output is an array of PFNs and
per-pfn flags, and it has various modes of reading.
This is necessary before RDMA ODP can be converted, as we don't want
to have weird corner case regressions, which is still a looking
forward item. Ralph has a nice tester for this routine, but it is
waiting for feedback from the selftests maintainers.
Summary:
- 9 bug fixes
- Allow pgmap to track the 'owner' of a DEVICE_PRIVATE - in this case
the owner tells the driver if it can understand the DEVICE_PRIVATE
page or not. Use this to resolve a bug in nouveau where it could
touch DEVICE_PRIVATE pages from other drivers.
- Remove a bunch of dead, redundant or unused code and flags
- Clarity improvements to hmm_range_fault()"
