Merge tag 'libcrypto-tests-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library test updates from Eric Biggers:
"Add KUnit test suites for the Poly1305, SHA-1, SHA-224, SHA-256,
SHA-384, and SHA-512 library functions.

These are the first KUnit tests for lib/crypto/. So in addition to
being useful tests for these specific algorithms, they also establish
some conventions for lib/crypto/ testing going forwards.

The new tests are fairly comprehensive: more comprehensive than the
generic crypto infrastructure's tests. They use a variety of
techniques to check for the types of implementation bugs that tend to
occur in the real world, rather than just naively checking some test
vectors. (Interestingly, poly1305_kunit found a bug in QEMU)

The core test logic is shared by all six algorithms, rather than being
duplicated for each algorithm.

Each algorithm's test suite also optionally includes a benchmark"

This also results in a boot stall when running the code in qemu:loongarch.

Initializing the worker with INIT_WORK_ONSTACK() fixes the problem.
