In fact I doubt we need a barrier at all...

Yeah, I'm not sure what I was thinking. There's need for a barrier
before the invalidation to make sure that a stale entry doesn't get
re-entered into the TLB, and it's already done before the call. I have
no good explanation for why I added that one.

I'll respin, test and repost the patch tomorrow.
