Ah, that makes sense. Could we have a comment documenting the
rationale, please? Something like:

/* vmload has just updated the content of RAM, bypassing the
 * usual mechanisms that ensure we flush TBs for writes to
 * memory we've translated code from. So we must flush all TBs,
 * which will now be stale.
