[PATCH 0/2] mm/hmm: two bug fixes for hmm_range_fault()

[Ralph Campbell]

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
process. The tests aren't quite ready to be posted as a patch.
I'm posting the fixes now since I thought they shouldn't wait.
They should probably have a fixes line but with all the HMM changes,
I wasn't sure exactly which commit to use.

These are based on top of Jason's latest hmm branch.
