If there are no further comments, I will send this as a patchset without RFC
later this week.
Since [1] already landed in mmotm, I will pull out the dependency for [2], and
change both devm/HMM code.

[1] https://patchwork.kernel.org/cover/10617699/
[2] https://patchwork.kernel.org/cover/10613425/

Thanks
