That means an NMI that happens outside guest code (for example, in the

Hmm, true. The same is true for an NMI that happens between VMSAVE and
STGI but that window is smaller. Anyway, I think we don't need the
busy-wait loop. The NMI should be executed at a well defined point and
we set the cpu_var back to NULL after that point.
The point is not well defined. Considering there are already at least
two implementations svm, I don't want to rely on implementation details.
We could tune the position of the loop so that zero iterations are
executed on the implementations we know about.
