[ Upstream commit c67b553a4f4a8bd921e4c9ceae00e111be09c488 ]
aria_aesni_avx_encrypt_16way(), aria_aesni_avx_decrypt_16way(), aria_aesni_avx_ctr_crypt_16way(), aria_aesni_avx_gfni_encrypt_16way(), aria_aesni_avx_gfni_decrypt_16way(), and aria_aesni_avx_gfni_ctr_crypt_16way() are called via indirect function calls. Therefore they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause their type hashes to be emitted when the kernel is built with CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure.
