Subject: [PATCH 00/12] RISC-V: provide some accelerated cryptography implementations using vector extensions

This series provides cryptographic implementations using the vector crypto
extensions[1] including:
1. AES cipher
2. AES with CBC/CTR/ECB/XTS block modes
3. ChaCha20 stream cipher
4. GHASH for GCM
5. SHA-224/256 and SHA-384/512 hash
6. SM3 hash
7. SM4 cipher

This patch set is based on Heiko Stuebner's work at:
Link: https://lore.kernel.org/all/20230711153743.1970625-1-heiko@sntech.de/

The implementations reuse the perl-asm scripts from OpenSSL[2] with some
changes adapting for the kernel crypto framework.
The perl-asm scripts generate the opcodes into `.S` files instead of asm
mnemonics. The reason for using opcodes is because the assembler hasn't
supported the vector-crypto extensions yet.

All changes pass the kernel run-time crypto self tests and the extra tests
with vector-crypto-enabled qemu.

This series depend on:
1. kernel 6.6-rc7
Link: https://github.com/torvalds/linux/commit/05d3ef8bba77c1b5f98d941d8b2d4aeab8118ef1
2. support kernel-mode vector
Link: https://lore.kernel.org/all/20230721112855.1006-1-andy.chiu@sifive.com/
3. vector crypto extensions detection
Link: https://lore.kernel.org/lkml/20231017131456.2053396-1-cleger@rivosinc.com/
4. fix the error message:
    alg: skcipher: skipping comparison tests for xts-aes-aesni because
    xts(ecb(aes-generic)) is unavailable
