[PATCH 3/6] crypto: sha512-mb - submit/flush routines for AVX2
From: Megha Dey
Date: Mon Jun 27 2016 - 13:14:34 EST
From: Megha Dey <megha.dey@xxxxxxxxxxxxxxx>
This patch introduces the routines used to submit and flush buffers
belonging to SHA512 crypto jobs to the SHA512 multibuffer algorithm.
It is implemented mostly in assembly optimized with AVX2 instructions.
