The "inv" (invalidate) instruction is generally less safe than "finv" (flush and invalidate), as it will drop dirty data from the cache. It turns out we have almost no need for "inv" (other than for the older 32-bit architecture in some limited cases), so convert to "finv" where possible and delete the extra "inv" infrastructure.
