There's a newer version:

https://lore.kernel.org/all/20251027095602.1154418-1-aneesh.kumar@xxxxxxxxxx/

This would allow upstreaming at least the three X.509 patches at the
beginning of my CMA series (and Alistair's rSPDM series) and thus
reduce the patch count a little bit.

However I don't know how far along Aneesh's CCA work is.

Note that David Howells' introduction of ML-DSA in v7.0 moves around
a lot of the X.509 code so the three X.509 patches for CMA will no longer
apply cleanly:

https://lore.kernel.org/all/2977832.1770384806@xxxxxxxxxxxxxxxxxxxxxx/

I'll rebase my development branch after v7.0-rc1 is out and Aneesh can
then pick up the latest version from it:
