From 2d84772bf858b2cb9b3525ceb2387686ea262d50 Mon Sep 17 00:00:00 2001 From: Anatoly Burakov Date: Wed, 11 Apr 2018 13:29:48 +0100 Subject: [PATCH] crypto/qat: use contiguous allocation for DMA memory All hardware drivers should allocate IOVA-contiguous memzones for their hardware resources. Also, remove the weird page alignment code.
