When the ARM AES instruction based crypto driver was introduced, there were no known implementations that could benefit from a 4-way interleave, and so a 3-way interleave was used instead. Since we have sufficient space in the SIMD register file, let's switch to a 4-way interleave to align with the 64-bit driver, and to ensure that we can reach optimum performance when running under emulation on high end 64-bit cores.

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.
