Dang, I can't make it through. The revert on main conflicts with too many files and can't be cherry-picked as it, and if I revert first conflicting areas, the cherry-pick make the PR un-buildable (due to LoongArch modified files I believe). There are 5k commit behind the branch already, which makes the changes quite hard.
