The GFNI routines in the AVX version of the ARIA implementation now use
explicit VMOVDQA instructions to load the constant input vectors, which
means they must be 16 byte aligned. So ensure that this is the case, by
dropping the section split and the incorrect .align 8 directive, and
emitting the constants into the 16-byte aligned section instead.
Note that the AVX2 version of this code deviates from this pattern, and
does not require a similar fix, given that it loads these contants as
8-byte memory operands, for which AVX2 permits any alignment.

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 Restructured Text 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.
