Delete crypto/sha512_generic.c, which provided "generic" SHA-384 and SHA-512 crypto_shash algorithms. Replace it with crypto/sha512.c which provides SHA-384, SHA-512, HMAC-SHA384, and HMAC-SHA512 crypto_shash algorithms using the corresponding library functions. This is a prerequisite for migrating all the arch-optimized SHA-512 code (which is almost 3000 lines) to lib/crypto/ rather than duplicating it. Since the replacement crypto_shash algorithms are implemented using the (potentially arch-optimized) library functions, give them cra_driver_names ending with "-lib" rather than "-generic". Update crypto/testmgr.c and one odd driver to take this change in driver name into account. Besides these cases which are accounted for, there are no known cases where the cra_driver_name was being depended on. This change does mean that the abstract partial block handling code in crypto/shash.c, which got added in 6.16, no longer gets used. But that's fine; the library has to implement the partial block handling anyway, and it's better to do it in the library since the block size and other properties of the algorithm are all fixed at compile time there, resulting in more streamlined code.

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.
