What an obvious filename ;-)

I guess we should put all these header files together into one again,
but that is hard to do without regressing things (I suspect this is
where the mystery power4 stems from as well, fwiw).

The patch looks fine.  Okay for trunk.  Also okay for any backports you
want (after waiting to see if it creates problems on trunk, as usual).

Thanks!
