Pull AES-GCM optimizations from Eric Biggers:
"More optimizations and cleanups for the x86_64 AES-GCM code:
- Add a VAES+AVX2 optimized implementation of AES-GCM. This is very
helpful on CPUs that have VAES but not AVX512, such as AMD Zen 3.
- Make the VAES+AVX512 optimized implementation of AES-GCM handle
large amounts of associated data efficiently.
- Remove the "avx10_256" implementation of AES-GCM. It's superseded
by the VAES+AVX2 optimized implementation.
- Rename the "avx10_512" implementation to "avx512"
Overall, this fills in a gap where AES-GCM wasn't fully optimized on
some recent CPUs. It also drops code that won't be as useful as
initially expected due to AVX10/256 being dropped from the AVX10 spec"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
