+Subject: [PATCH] x86: Disable AVX Fast Unaligned Load on Hygon 1/2/3
+
+- Performance testing revealed significant memcpy performance degradation
+  when bit_arch_AVX_Fast_Unaligned_Load is enabled on Hygon 3.
+- Hygon confirmed AVX performance issues in certain memory functions.
+- Glibc benchmarks show SSE outperforms AVX for
+  memcpy/memmove/memset/strcmp/strcpy/strlen and so on.
+- Hardware differences primarily in floating-point operations don't justify
+  AVX usage for memory operations.
