Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
198429631a
Provide a version of the core AES transform to the aegis128 SIMD code that does not rely on the special AES instructions, but uses plain NEON instructions instead. This allows the SIMD version of the aegis128 driver to be used on arm64 systems that do not implement those instructions (which are not mandatory in the architecture), such as the Raspberry Pi 3. Since GCC makes a mess of this when using the tbl/tbx intrinsics to perform the sbox substitution, preload the Sbox into v16..v31 in this case and use inline asm to emit the tbl/tbx instructions. Clang does not support this approach, nor does it require it, since it does a much better job at code generation, so there we use the intrinsics as usual.

README
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.
