Make jitterentropy use "sha3-256" instead of "sha3-256-generic", as the ability to explicitly request the generic code is going away. It's not worth providing a special generic API just for jitterentropy. There are many other solutions available to it, such as doing more iterations or using a more effective jitter collection method. Moreover, the status quo is that SHA-3 is quite slow anyway. Currently only arm64 and s390 have architecture-optimized SHA-3 code. I'm not familiar with the performance of the s390 one, but the arm64 one isn't actually that much faster than the generic code anyway. Note that jitterentropy should just use the library API instead of crypto_shash. But that belongs in a separate change later.

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.
