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
