crypto: arm64/gcm - use variably sized key struct
Ard Biesheuvel authored

Now that the ghash and gcm drivers are split, we no longer need to allocate
a key struct for the former that carries powers of H that are only used by
the latter. Also, take this opportunity to clean up the code a little bit.

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.
