This replaces the scalar AES cipher that originates in the OpenSSL project with a new implementation that is ~15% (*) faster (on modern cores), and reuses the lookup tables and the key schedule generation routines from the generic C implementation (which is usually compiled in anyway due to networking and other subsystems depending on it). Note that the bit sliced NEON code for AES still depends on the scalar cipher that this patch replaces, so it is not removed entirely yet. * On Cortex-A57, the performance increases from 17.0 to 14.9 cycles per byte for 128-bit keys.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
