The latest extension detection patch version is v5.
Link: https://lore.kernel.org/lkml/20231114141256.126749-1-cleger@rivosinc.com/
It's still under reviewing.
But I think the checking codes used in this crypto patch series will not change.
We could just wait and rebase when it's merged.

The latest kernel-mode vector patch version is v3.
Link: https://lore.kernel.org/all/20231019154552.23351-1-andy.chiu@sifive.com/
This patch doesn't work with qemu(hit kernel panic when using vector). It's not
clear for the status. Could we still do the reviewing process for the gluing code and
the crypto asm parts?
