FYI, applied to
https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git/log/?h=libcrypto-next

Additional reviews and acks would be greatly appreciated, though!

As per Linus's request, I reordered the KUnit tests (patches 4-5) to be last.
I'll try to keep them last as additional non-test patches get applied.

I also adjusted commit titles slightly to match what I'm planning to use for
lib/crypto and lib/crc going forwards:
    
        lib/(crypto|crc): ((algorithm|arch|arch/algorithm):)? Subject

    e.g.

        lib/crypto: sha512: Add KUnit tests for SHA-384 and SHA-512
        lib/crypto: x86: Move arch/x86/lib/crypto/ into lib/crypto/
        lib/crypto: x86/sha512: Migrate optimized SHA-512 code to library
        lib/crypto: Explicitly include <linux/export.h>
