The addition of SipHash to lib/ predated the existence of the lib/crypto/ directory. Since SipHash is a cryptographic algorithm, move it from the top-level lib/ directory to lib/crypto/. (This does mean HalfSipHash comes with it too, as it's in the same files. But lib/crypto/ still seems like the proper place for both.) Specifically: - Move both siphash.c and siphash_kunit.c. Keep the header <linux/siphash.h> as-is for now. - Drop the dedicated MAINTAINERS entry for SipHash, as per the suggestion from Jason (https://lore.kernel.org/r/asB7QVFMlgKgbje2@zx2c4.com/). The C files now just fold up to the "CRYPTO LIBRARY" entry. Add the header explicitly, as it otherwise would be left unmaintained. - Move the kconfig option that controls the KUnit test. Put "CRYPTO_LIB" in its name and update the prompt and help text to make it consistent with the other crypto library test options. - Enable the KUnit test in lib/crypto/.kunitconfig. - Link to siphash.rst from the appropriate place in libcrypto-hash.rst. - Use obj-y instead of lib-y, for consistency with the fact that currently lib/crypto/ doesn't use kbuild's support for library file goals. We could keep it as lib-y, but virtually every kernel needs SipHash support anyway (with vsprintf, printk, IPv4, IPv6, etc. depending on it) so there is no practical difference in this case.
