[PATCH 0/4] crypto: arm64/aes-blk - cleanups and optimizations for XTS/CTS-CBC

[ard.biesheuvel@linaro.org (Ard Biesheuvel)]

Some cleanups and optimizations for the arm64  AES skcipher routines.

Patch #1 fixes the peculiar use of u8 arrays to refer to AES round keys,
which are natively arrays of u32.

Patch #2 partially reverts the use of NEON yield calls, which is not
needed for skciphers.

Patch #3 adds support for cts(cbc(aes)) in the NEON chaining mode handling.

Patch #4 tweaks the XTS handling to remove a literal load from the inner
loop.
