From 0d61c3f1449a70fbf70f99648c4075b1e758be4d Mon Sep 17 00:00:00 2001 From: Kai Ye Date: Tue, 5 Jan 2021 14:12:03 +0800 Subject: [PATCH] crypto: hisilicon/qm - SVA bugfixed on Kunpeng920 Kunpeng920 SEC/HPRE/ZIP cannot support running user space SVA and kernel Crypto at the same time. Therefore, the algorithms should not be registered to Crypto as user space SVA is enabled.
