Eric Biggers 70cf3d6fe7 crypto: arm64/ghash - Fix incorrect output from ghash-neon commit `f6a458746f` upstream. Commit `9a7c987fb9` ("crypto: arm64/ghash - Use API partial block handling") made ghash_finup() pass the wrong buffer to ghash_do_simd_update(). As a result, ghash-neon now produces incorrect outputs when the message length isn't divisible by 16 bytes. Fix this. (I didn't notice this earlier because this code is reached only on CPUs that support NEON but not PMULL. I haven't yet found a way to get qemu-system-aarch64 to emulate that configuration.)

README

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.
