Since commit9d7a0ab1c7("crypto: ahash - Handle partial blocks in API"), the recently-added export_core() and import_core() methods in struct shash_alg have effectively become mandatory (even though it is not tested or enforced), since legacy drivers that need a fallback depend on them. Make crypto/sha512.c compatible with these legacy drivers by adding export_core() and import_core() methods to it.

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.
