aesbs_setkey() and aesbs_cbc_ctr_setkey() allocate struct crypto_aes_ctx
on the stack. On arm64, the kernel-mode NEON context is also stored on
the stack, causing the combined frame size to exceed 1024 bytes and
triggering -Wframe-larger-than= warnings.
Allocate struct crypto_aes_ctx on the heap instead and use
kfree_sensitive() to ensure the key material is zeroed on free.
Use a goto-based cleanup path to ensure kfree_sensitive() is always
called.

Switch from the old AES library functions (which use struct
crypto_aes_ctx) to the new ones (which use struct aes_enckey). This
eliminates the unnecessary computation and caching of the decryption
round keys. The new AES en/decryption functions are also much faster
and use AES instructions when supported by the CPU.
Note that in addition to the change in the key preparation function and
the key struct type itself, the change in the type of the key struct
results in aes_encrypt() (which is temporarily a type-generic macro)
calling the new encryption function rather than the old one.

Move the ARM64 optimized AES key expansion and single-block AES
en/decryption code into lib/crypto/, wire it up to the AES library API,
and remove the superseded crypto_cipher algorithms.
The result is that both the AES library and crypto_cipher APIs are now
optimized for ARM64, whereas previously only crypto_cipher was (and the
optimizations weren't enabled by default, which this fixes as well).
Note: to see the diff from arch/arm64/crypto/aes-ce-glue.c to

Now that the AES library's performance has been improved, replace
aes_generic.c with a new file aes.c which wraps the AES library.
In preparation for making the AES library actually utilize the kernel's
existing architecture-optimized AES code including AES instructions, set
the driver name to "aes-lib" instead of "aes-generic". This mirrors
what's been done for the hash algorithms. Update testmgr.c accordingly.
Since this removes the crypto_aes_set_key() helper function, add
temporary replacements for it to arch/arm/crypto/aes-cipher-glue.c and
arch/arm64/crypto/aes-cipher-glue.c. This is temporary, as that code
will be migrated into lib/crypto/ in later commits.

The call to sha256() occurs in code that is built when either
CRYPTO_AES_ARM64_CE_BLK or CRYPTO_AES_ARM64_NEON_BLK. The option
CRYPTO_AES_ARM64 is unrelated, notwithstanding its documentation. I'll
be removing CRYPTO_AES_ARM64 soon anyway, but before doing that, fix
where CRYPTO_LIB_SHA256 is selected from.

Instead of crypto_ft_tab and crypto_it_tab from aes_generic.c, use
aes_enc_tab and aes_dec_tab from lib/crypto/aes.c. These contain the
same data in the first 1024 bytes (which is the part that this code
uses), so the result is the same. This will allow aes_generic.c to
eventually be removed.

Migrate the arm64 NEON implementation of NH into lib/crypto/. This
makes the nh() function be optimized on arm64 kernels.
Note: this temporarily makes the adiantum template not utilize the arm64
optimized NH code. This is resolved in a later commit that converts the
adiantum template to use nh() instead of "nhpoly1305".

Commit 9a7c987fb92b ("crypto: arm64/ghash - Use API partial block
handling") made ghash_finup() pass the wrong buffer to
ghash_do_simd_update(). As a result, ghash-neon now produces incorrect
outputs when the message length isn't divisible by 16 bytes. Fix this.
(I didn't notice this earlier because this code is reached only on CPUs
that support NEON but not PMULL. I haven't yet found a way to get
qemu-system-aarch64 to emulate that configuration.)

The ciphertext stealing logic in the AES-XTS implementation creates a
separate ksimd scope to call into the FP/SIMD core routines, and in some
cases (CONFIG_KASAN_STACK is one, but there might be others), the 528
byte kernel mode FP/SIMD buffer that is allocated inside this scope is
not shared with the preceding ksimd scope, resulting in unnecessary
stack bloat.
Considering that
a) the XTS ciphertext stealing logic is never called for block
encryption use cases, and XTS is rarely used for anything else,
b) in the vast majority of cases, the entire input block is processed
during the first iteration of the loop,
we can combine both ksimd scopes into a single one with no practical
impact on how often/how long FP/SIMD is en/disabled, allowing us to
reuse the same stack slot for both FP/SIMD routine calls.

Kernel mode NEON sections are now preemptible on arm64, and so there is
no need to yield it when calling APIs that may sleep.
Also, move the calls to kernel_neon_end() to the same scope as
kernel_neon_begin(). This is needed for a subsequent change where a
stack buffer is allocated transparently and passed to
kernel_neon_begin().
While at it, simplify the logic.

Migrate the arm64 implementation of POLYVAL into lib/crypto/, wiring it
up to the POLYVAL library interface. This makes the POLYVAL library be
properly optimized on arm64.
This drops the arm64 optimizations of polyval in the crypto_shash API.
That's fine, since polyval will be removed from crypto_shash entirely
since it is unneeded there. But even if it comes back, the crypto_shash
API could just be implemented on top of the library API, as usual.
Adjust the names and prototypes of the assembly functions to align more
closely with the rest of the library code.

- Use size_t lengths, to match the library.
- Pass the block size instead of digest size, and add support for the
block size that SHAKE128 uses. This allows the code to be used with
SHAKE128 and SHAKE256, which don't have the concept of a digest size.
SHAKE256 has the same block size as SHA3-256, but SHAKE128 has a
unique block size. Thus, there are now 5 supported block sizes.
Don't bother changing the "glue" code arm64_sha3_update() too much, as
it gets deleted when the SHA-3 code is migrated into lib/crypto/ anyway.
