This just moves code around -- no code changes in this patch. This
wil let BPF-based tracing link against the SHA256 core code without
depending on the crypto core.

There is a similar standalone code present for SHA-1 or ChaCha20. However,
this code lives in lib/.
Thus, shouldn't the SHA-256 core code be moved to lib/ as well?

What's wrong with lib/sha256.c? It's already there.
That is currently not build under lib/ it is only build as part of
the helper executable which deals with transitioning from one kernel to
the next on kexec, specifically it is used by arch/x86/purgatory/purgatory.c
and also be the s390 purgatory code.
Since the purgatory use is in a separate binary / name space AFAICT, we
could add sha256.o to lib/Makefile and then I could use that, but then the
normal kernel image would have 2 SHA256 implementations.

Hans
