v5 cover crypto: aria: implement aria-avx2 and aria-avx512

This patchset is to implement aria-avx2 and aria-avx512. There are some differences between aria-avx, aria-avx2, and aria-avx512, but they are not core logic(s-box, diffusion layer).

ARIA-AVX2
It supports 32way parallel processing using 256bit registers. Like ARIA-AVX, it supports both AES-NI based s-box layer algorithm and GFNI based s-box layer algorithm.
These algorithms are the same as ARIA-AVX except that AES-NI doesn't support 256bit registers, so it is used twice.

ARIA-AVX512
It supports 64way parallel processing using 512bit registers. It supports only GFNI based s-box layer algorithm.

PATCH v5 1/4 crypto: aria: add keystream array into request ctx

avx accelerated aria module used local keystream array. But, keystream array size is too big.
So, it puts the keystream array into request ctx.

PATCH v5 2/4 crypto: aria: do not use magic number offsets of aria_ctx

In reply to Taehee Yoo

aria-avx assembly code accesses members of aria_ctx with magic number offset. If the shape of struct aria_ctx is changed carelessly, aria-avx will not work.
So, we need to ensure accessing members of aria_ctx with correct offset values, not with magic numbers.

It adds ARIA_CTX_enc_key, ARIA_CTX_dec_key, and ARIA_CTX_rounds in the asm-offsets.c So, correct offset definitions will be generated. aria-avx assembly code can access members of aria_ctx safely with these definitions.

PATCH v5 3/4 crypto: aria: implement aria-avx2

In reply to Taehee Yoo

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;

+SYM_FUNC_START(aria_aesni_avx2_encrypt_32way)

Please use SYM_TYPED_FUNC_START (and include <linux/cfi_types.h>) for all assembly functions that are called via indirect function calls. Otherwise the code will crash when built with CONFIG_CFI_CLANG=y.

Okay, I will use SYM_TYPED_FUNC_START for avx2 and avx512 in the v6 patchset.

Thanks a lot!

PATCH v5 4/4 crypto: aria: implement aria-avx512

In reply to Taehee Yoo

aria-avx512 implementation uses AVX512 and GFNI.
It supports 64way parallel processing.
So, byteslicing code is changed to support 64way parallel. And it exports some aria-avx2 functions such as encrypt() and decrypt().

AVX and AVX2 have 16 registers.
They should use memory to store/load state because of lack of registers. But AVX512 supports 32 registers.
So, it doesn't require store/load in the s-box layer.
It means that it can reduce overhead of store/load in the s-box layer. Also code become much simpler.

Benchmark with modprobe tcrypt mode=610 num_mb=8192, i3-12100:

v5:
- Set CRYPTO_ALG_SKCIPHER_REQSIZE_LARGE flag.

v4:
- Add aria_avx512_request_ctx for keystream array.

v3:
- Use ARIA_CTX_enc_key, ARIA_CTX_dec_key, and ARIA_CTX_rounds defines.

v2:
- Add new "add keystream array into struct aria_ctx" patch.
- Use keystream array in the aria_ctx instead of stack memory
