a fix to v5, now *really* fixing the wrong priority of SMCCC vs. RNDR in arch_get_random_seed_long_early(). Apologies for messing this up in v5 and thanks to broonie for being on the watch! Will, Catalin: it would be much appreciated if you could consider taking patch 1/5. This contains the common definitions, and is a prerequisite for every other patch, although they are somewhat independent and likely will need to go through different subsystems. [...]Applied the first patch only to arm64 (for-next/rng), thanks! [1/5] firmware: smccc: Add SMCCC TRNG function call IDs https://git.kernel.org/arm64/c/67c6bb56b649 What's the plan for the rest of the series, and I think the related change over at [1]?Given that Ted seems to have lost interest in /dev/random patches, I was hoping [1] could be taken via the arm64 tree instead. Without this patch, I don't think we should expose the SMCCC RNG interface via arch_get_random_seed(), given how insanely often it will be called in that case.
Ok, let's give that a shot -- I'll additionally pick patches 2 and 4 out of this series, and merge in the /dev/random change on its own branch in case there are any late objections.
