This patch introduces the assembly routine to do a by8 AES CBC encryption
in support of the AES CBC multi-buffer implementation.
Encryption of 8 data streams of a key size are done simultaneously.

This patch introduces the data structures and prototypes of functions
needed for doing AES CBC encryption using multi-buffer. Included are
the structures of the multi-buffer AES CBC job, job scheduler in C and
data structure defines in x86 assembly code.

In this patch, the infrastructure needed to support multibuffer
encryption implementation is added:
a) Enhace mcryptd daemon to support blkcipher requests.
b) Update configuration to include multi-buffer encryption build support.
c) Add support to crypto scatterwalk support that can sleep durin
This patch introduces the multi-buffer job manager which is responsible
for submitting scatter-gather buffers from several AES CBC jobs
to the multi-buffer algorithm. The glue code interfaces with the
underlying algorithm that handles 8 data streams of AES CBC encryption
in parallel. AES key expan
This patch implements in-order scheduler for encrypting multiple buffers
in parallel supporting AES CBC encryption with key sizes of
128, 192 and 256 bits. It uses 8 data lanes by taking advantage of the
SIMD instructions with XMM registers.
The multibuffer manager and scheduler is mostly written
In this patch series, we introduce AES CBC encryption that is parallelized
on x86_64 cpu with XMM registers. The multi-buffer technique encrypt 8
data streams in parallel with SIMD instructions. Decryption is handled
as in the existing AESNI Intel CBC implementation which can already
parallelize d

Added entry for sm3-256 to the following tables:
* hash_algo_name
* hash_digest_size
Needed for TPM 2.0 trusted key sealing.
