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  

I can't see how the rest of the patches can go via any other tree
if all the definitions are in the first one.

Andre, can you explain what your plan is?

Well, I don't really have a great solution for that, other than hoping
that 1/5 makes it into Linus' master at some point.

I see that it's a stretch, but pulling 1/5 into 5.11 now would
prepare the stage for the others to go via any tree, into 5.12-rc1?

Or you could maybe take both 1/5 and 5/5 into your kvm-arm tree, and
would hope that a git rebase later would sort this out for you?

But I think you are much more experienced in those kind of issues, so
happy to hear about any other solutions.

for-next/rng is a stable branch, so anybody who wants the first patch can
just pull it (without anything I queue on top).

Will
