Ard Biesheuvel 2fd58d8bb0 crypto: tcrypt - avoid signed overflow in byte count
[ Upstream commit 303fd3e1c771077e32e96e5788817f025f0067e2 ]

The signed long type used for printing the number of bytes processed in
tcrypt benchmarks limits the range to -/+ 2 GiB, which is not sufficient
to cover the performance of common accelerated ciphers such as AES-NI
when benchmarked with sec=1. So switch to u64 instead.

While at it, fix up a missing printk->pr_cont conversion in the AEAD
benchmark.

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.
