That's 2.5% - a huge difference. Particularly since kernel build times
shouldn't even be that kernel-intensive.

I think there's something else going on than the nops. Same config?
There are likely many other differences between 5.10.19 and 5.12-rc3.

So can you check just plain 5.12-rc3 and then 5.12-rc3 plus x86-nops,
with otherwise identical configuration?
