	sm3_neon_transform() is called via indirect function calls. Therefore it needs to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause its type hash 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 call).

2022-11-04	crypto: arm64/sm3 - add NEON assembly implementation	Tianjia Zhang
	This patch adds the NEON acceleration implementation of the SM3 hash algorithm. The main algorithm is based on SM3 NEON accelerated work of the libgcrypt project. Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 326 mode of tcrypt, and compares the performance data of sm3-generic and sm3-ce. The abscissas are blocks of different lengths. The data is tabulated and the unit is Mb/s: update-size \| 16 64 256 1024 2048 4096 8192 ---------------+-------------------------------------------------------- sm3-generic \| 185.24 221.28 301.26 307.43 300.83 308.82 308.91 sm3-neon \| 171.81 220.20 322.94 339.28 334.09 343.61 343.87 sm3-ce \| 227.48 333.48 502.62 527.87 520.45 534.91 535.40 Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
