You also have #ifdef CONFIG_AS_AVX / #endif missing in 'sha256-avx-asm.S', 'sha256-avx2-asm.S', 'sha512-avx-asm.S' and 'sha512-avx2-asm.S'. -Jussi -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
