Thanks for doing this, it all looks reasonable to me. But there is one
thing missing which needs to be done before we can move forward with
this.

There was a discussion about the Kconfig symbol naming used in
mm_struct. Please see the discussion here:

Please update this patch-set to solve this and I will take the series.
