- Use memcpy_sglist to replace null skcipher
- Rename CRYPTO_TESTS to CRYPTO_BENCHMARK
- Flip CRYPTO_MANAGER_DISABLE_TEST into CRYPTO_SELFTESTS
- Hide CRYPTO_MANAGER
- Add delayed freeing of driver crypto_alg structures
Compression:
- Allocate large buffers on first use instead of initialisation in scomp
- Drop destination linearisation buffer in scomp
- Move scomp stream allocation into acomp
- Add acomp scatter-gather walker
- Remove request chaining

- Fix shash documentation to disallow usage in hard IRQs
Algorithms:
- Remove unnecessary SIMD fallback code on x86 and arm/arm64
- Drop avx10_256 xts(aes)/ctr(aes) on x86
- Improve avx-512 optimisations for xts(aes)
- Move chacha arch implementations into lib/crypto
- Move poly1305 into lib/crypto and drop unused Crypto API algorithm
- Disable powerpc/poly1305 as it has no SIMD fallback
- Move sha256 arch implementations into lib/crypto
- Convert deflate to acomp
- Set block size correctly in cbcmac
Drivers:
- Do not use sg_dma_len before mapping in sun8i-ss
- Fix warm-reboot failure by making shutdown do more work in qat
- Add locking in zynqmp-sha
