[J][PATCH 0/2] In-kernel crypto: SIMD implementation of chacha20 (LP: 1853152)

[frank.heimes at canonical.com]

BugLink: https://bugs.launchpad.net/bugs/1853152

Recent kernel releases provide support for the chacha20 cipher and among
others use it to compute pseudo random numbers for /dev/urandom. Chacha20
is a type of algorithm that can be accelerated using SIMD instructions.
The goal of this item is to use z System SIMD instruction
to implement chacha20.
