In the long term I'd like us to be able to compile the whole (or at least most of) the kernel with one "-combine -fwhole-program" gcc call which should bring the same positive effect plus enables gcc to do additional optimizations.
That's meant as a remark, not against your patch (which is for a lower hanging fruit).
