aes-gcm-vaes-avx512.S (originally aes-gcm-avx10-x86_64.S) was designed to support multiple maximum vector lengths, while still utilizing AVX512 / AVX10 features such as the increased number of vector registers. However, the support for multiple maximum vector lengths turned out to not be useful. Support for maximum vector lengths other than 512 bits was removed from the AVX10 specification, which leaves "avoiding overly-eager downclocking" as the only remaining use case for limiting AVX512 / AVX10 code to 256-bit vectors. But this issue has gone away in new CPUs, and the separate VAES+AVX2 code which I ended up having to write anyway provides nearly as good 256-bit support. Therefore, clean up this code to not be written in terms of a generic vector length, but rather just assume 512-bit vectors.

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.
