The SHA-3 library now utilizes the same s390 SHA-3 acceleration capabilities as the arch/s390/crypto/ SHA-3 crypto_shash algorithms. Moreover, crypto/sha3.c now uses the SHA-3 library. The result is that all SHA-3 APIs are now s390-accelerated without any need for the old SHA-3 code in arch/s390/crypto/. Remove this superseded code. Also update the s390 defconfig and debug_defconfig files to enable CONFIG_CRYPTO_SHA3 instead of CONFIG_CRYPTO_SHA3_256_S390 and CONFIG_CRYPTO_SHA3_512_S390. This makes it so that the s390-optimized SHA-3 continues to be built when either of these defconfigs is used.

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.
