I got some build warnings with W=1:
arch/x86/coco/sev/core.c:
arch/x86/crypto/aria_aesni_avx2_glue.c:
warning: EXPORT_SYMBOL() is used,
but #include <linux/export.h> is missing

arch/x86/crypto/curve25519-x86_64.c:

arch/x86/crypto/serpent_avx_glue.c:
warning: EXPORT_SYMBOL() is used,
but #include <linux/export.h> is missing
arch/x86/crypto/sm4_aesni_avx_glue.c:
warning: EXPORT_SYMBOL() is used,

arch/x86/crypto/twofish_glue.c:
warning: EXPORT_SYMBOL() is used,
but #include <linux/export.h> is missing
arch/x86/crypto/twofish_glue_3way.c:
warning: EXPORT_SYMBOL() is used,
but #include <linux/export.h> is missing
so I fixed these build warnings for x86_64.

Stop wrapping skcipher and aead algorithms with the crypto SIMD helper
(crypto/simd.c). The only purpose of doing so was to work around x86
not always supporting kernel-mode FPU in softirqs. Specifically, if a
hardirq interrupted a task context kernel-mode FPU section and then a
softirqs were run at the end of that hardirq, those softirqs could not
use kernel-mode FPU. This has now been fixed. In combination with the
fact that the skcipher and aead APIs only support task and softirq
contexts, these can now just use kernel-mode FPU unconditionally on x86.
This simplifies the code and improves performance.

The minimum version of binutils for kernel build is currently 2.23 and
it doesn't support GFNI.
So, it fails to build the aria-avx2 if the old binutils is used.
The code using GFNI is an optional part of aria-avx2.
So, it disables GFNI part in it when the old binutils is used.
Fixes: 37d8d3ae7a58 ("crypto: x86/aria - implement aria-avx2")

aria-avx2 implementation uses AVX2, AES-NI, and GFNI.
It supports 32way parallel processing.
So, byteslicing code is changed to support 32way parallel.
And it exports some aria-avx functions such as encrypt() and decrypt().
There are two main logics, s-box layer and diffusion layer.
These codes are the same as aria-avx implementation.
But some instruction are exchanged because they don't support 256bit
registers.
Also, AES-NI doesn't support 256bit register.
So, aesenclast and aesdeclast are used twice like below:
vextracti128 $1, ymm0, xmm6;
vaesenclast xmm7, xmm0, xmm0;
vaesenclast xmm7, xmm6, xmm6;
vinserti128 $1, xmm6, ymm0, ymm0;
