Pulled into next/drivers, but please try to make the changelogs more readable
in the future. No point listing each small patch here, instead say what you've
done overall and what the major things are. Right now, the merge commit
just duplicates the information like this:

which looks a bit silly. This also seemed like the right place
to add a bugfix that I had in my queue:

    soc: qcom/smem: add HWSPINLOCK dependency
    
    This fixes a build error when smem is enabled without hwspinlock:
