Please find a rebase of v2 on v6.14-rc2 on this branch:

https://github.com/l1k/linux/commits/doe

A portion of the crypto patches that were part of v2 have landed in v6.13.
So the rebased version has shrunk.

There was a bit of fallout caused by the upstreamed crypto patches
and dealing with that kept me occupied during the v6.13 cycle.
However I'm now back working on the PCI/CMA patches,
specifically the migration to netlink for retrieval of signatures
and measurements as discussed at Plumbers.

Thanks,

Lukas
