Instead of calculating the tag and returning it to the caller on decryption, use a SIMD compare and min across vector to perform the comparison. This is slightly more efficient, and removes the need on the caller's part to wipe the tag from memory if the decryption failed. While at it, switch to unsigned int when passing cryptlen and assoclen - we don't support input sizes where it matters anyway.

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.
