sha512_transform_ssse3(), sha512_transform_avx(), and
sha512_transform_rorx() 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 (if the compiler didn't happen to optimize out the indirect
calls).
Fixes: ccace936eec7 ("x86: Add types to indirectly called assembly functions")
