they are not exported, they can change at any time. The guard
ensures that they are verified at least on every version upgrade.

Adin Scannell fb613020c7 kvm: simplify floating point logic.
This reduces the number of floating point save/restore cycles required (since
we don't need to restore immediately following the switch, this always happens
in a known context) and allows the kernel hooks to capture state. This lets us
remove calls like "Current()".
