This series stems from [1], which outlined some rather bad bugs in the way we handle live system registers with VHE. As the discussion progressed, I decided to tighten things a bit, and found a couple more bugs in the process. I appreciate this is a bit big for a -rc, but at the same time some of the issues are rather annoying, and I'd like to make sure we address these for good.
