- * every time we wrap ASIDs, not every single time we switch.
- *
- * FIXME: We might improve performance by keeping ASIDs around
- * properly, though since the hypervisor direct-maps VAs to TSB
- * entries, we're likely to have lost at least the executable page
- * mappings by the time we switch back to the original mm.
