Depend on the generic ChaCha library routines instead of pulling in the generic ChaCha skcipher driver, which is more than we need, and makes managing the dependencies between the generic library, generic driver, accelerated library and driver more complicated. While at it, drop the logic to prefer the scalar code on short inputs. Turning the NEON on and off is cheap these days, and one major use case for ChaCha20 is ChaCha20-Poly1305, which is guaranteed to hit the scalar path upon every invocation (when doing the Poly1305 nonce generation) Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
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.
