AES-CCM (as used in WPA2 CCMP, for instance) typically involves authenticate-only data, and operates on a single network packet, and so the common case is for the authenticate, en/decrypt and finalize SIMD helpers to all be called exactly once in sequence. Since kernel_neon_end() now involves manipulation of the preemption state as well as the softirq mask state, let's reduce the number of times we are forced to call it to only once if we are handling this common case.

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.
