It assists as far as making sure the changes don't cause a
regression for the platform.

It looks like patch 6 will allow me to select ARM_MPU for the MPS3
config (by way of CPU_V7M being enabled). As I'm unable to test
what effect that has here, and I don't know when I'll be able to do
so, please check if not already done so.

Please never provide a branch on top of my for-next, it's an "unstable"
commit in that it's regenerated from several sub-branches (fixes, misc,
devel-stable, and whatever other work I want to include in linux-next.)
