with walk->vma == NULL if the start and end address are not contained

[PATCH 0/2] mm/hmm: two bug fixes for hmm_range_fault()
I have been working on converting Jerome's hmm_dummy driver and self
tests into a stand-alone set of tests to be included in
tools/testing/selftests/vm and came across these two bug fixes in the

[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:

Changes from v1 to v2:
Added AMD GPU to hmm_update removal.
Added 2 patches from Christoph.
Added 2 patches as
