#     crypto: arm64/chacha - fix hchacha_block_neon() for big endian
#     
#     On big endian arm64 kernels, the xchacha20-neon and xchacha12-neon
#     self-tests fail because hchacha_block_neon() outputs little endian words
#     but the C code expects native endianness.  Fix it to output the words in
#     native endianness (which also makes it match the arm32 version).
#     
#     Fixes: cc7cf991e9eb ("crypto: arm64/chacha20 - add XChaCha20 support")
