The latest extension detection patch version is v5.

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.

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?
