Instead of exposing the x86-optimized SHA-512 code via x86-specific crypto_shash algorithms, instead just implement the sha512_blocks() library function. This is much simpler, it makes the SHA-512 (and SHA-384) library functions be x86-optimized, and it fixes the longstanding issue where the x86-optimized SHA-512 code was disabled by default. SHA-512 still remains available through crypto_shash, but individual architectures no longer need to handle it. To match sha512_blocks(), change the type of the nblocks parameter of the assembly functions from int to size_t. The assembly functions actually already treated it as size_t.

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.
