It turns out I had misunderstood how the x86_match_cpu() function works.
It evaluates a logical OR of the matching conditions, not logical AND.
This caused the CPU feature checks for AEGIS to pass even if only SSE2
(but not AES-NI) was supported (or vice versa), leading to potential
crashes if something tried to use the registered algs.
This patch switches the checks to a simpler method that is used e.g. in
the Camellia x86 code.
The patch also removes the MODULE_DEVICE_TABLE declarations which
actually seem to cause the modules to be auto-loaded at boot, which is
not desired. The crypto API on-demand module loading is sufficient.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
