Simplify the kconfig entry for WIREGUARD: - Drop the selections of the arch-optimized ChaCha20, Poly1305, BLAKE2s, and Curve25519 code. These options no longer exist, as lib/crypto/ now enables the arch-optimized code automatically. - Drop the selection of CRYPTO. This was needed only to make the arch-optimized options visible. lib/crypto/ now handles these options internally, without any dependency on CRYPTO. - Drop the dependency on !KMSAN. This was needed only to avoid selecting arch-optimized code that isn't compatible with KMSAN. lib/crypto/ now handles the !KMSAN dependencies internally. - Add a selection of CRYPTO_LIB_UTILS, since WireGuard directly calls crypto_memneq(). This gets selected indirectly by CRYPTO_LIB_CURVE25519 and CRYPTO_LIB_CHACHA20POLY1305 anyway, but it's best to make this dependency explicit.

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.
