-# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
-# project. The module is, however, dual licensed under OpenSSL and
-# CRYPTOGAMS licenses depending on where you obtain it. For further
-# details see https://www.openssl.org/~appro/cryptogams/.
-# ====================================================================
-#
-# This module implements support for AES instructions as per PowerISA
-# specification version 2.07, first implemented by POWER8 processor.
-# The module is endian-agnostic in sense that it supports both big-
-# and little-endian cases. Data alignment in parallelizable modes is
-# handled with VSX loads and stores, which implies MSR.VSX flag being
-# set. It should also be noted that ISA specification doesn't prohibit
-# alignment exceptions for these instructions on page boundaries.
-# Initially alignment was handled in pure AltiVec/VMX way [when data
-# is aligned programmatically, which in turn guarantees exception-
-# free execution], but it turned to hamper performance when vcipher
-# instructions are interleaved. It's reckoned that eventual
-# misalignment penalties at page boundaries are in average lower
-# than additional overhead in pure AltiVec approach.
-#
-# May 2016
-#
-# Add XTS subroutine, 9x on little- and 12x improvement on big-endian
-# systems were measured.

-####################### WARNING: Here be dragons! #######################
-#
-# This code is written as 'ctr32', based on a 32-bit counter used
-# upstream. The kernel does *not* use a 32-bit counter. The kernel uses
-# a 128-bit counter.
-#
-# This leads to subtle changes from the upstream code: the counter
-# is incremented with vaddu_q_m rather than vaddu_w_m. This occurs in
-# both the bulk (8 blocks at a time) path, and in the individual block
-# path. Be aware of this when doing updates.
-#
-# See:
-# 1d4aa0b4c181 ("crypto: vmx - Fixing AES-CTR counter bug")
-# 009b30ac7444 ("crypto: vmx - CTR: always increment IV as quadword")
