Thanks! This mostly looked good to me.

I had actually meant that you would squash my fixes into your patches, 
instead of keeping them as separate ones.

After squashing such changes, it might have been interesting to get 
updated benchmarks in those commit messages (the ones that you have from 
Graviton 3). However in this case, these changes didn't really make much 
difference on out-of-order cores, only on in-order cores, so I guess 
there's not that much value in getting updated benchmarks from Graviton 3 
in this case.

So I went ahead and squashed those patches (and added co-authored-by lines 
where relevant), and pushed them now. Thanks for your contribution!
