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:
commit 90bb7e0e4f1ad8714f39db232ef14c588297346d

which looks a bit silly. This also seemed like the right place
to add a bugfix that I had in my queue:
commit 73ebb85444b0472d90bb70a1a9e6b5df3f92c14c

This fixes a build error when smem is enabled without hwspinlock:

Say y here to enable support for the Qualcomm Shared Memory Manager.
The driver provides an interface to items in a heap shared among all
and I applied that on top.
