Hi Folks,
There another feature that we might want to consider in the naming here:

Protection Keys for Supervisor pages is also called PKS. It's also not
entirely impossible that powerpc might want to start using this code at
some point, just like what happened with the userspace protection keys[1].
I don't think it's the end of the world either way, but it might save a
hapless user or kernel developer some confusion if we can avoid
including two "PKS" features in the kernel. I just wanted to make sure
we were aware of the other's existence. :)
