From de472e4a92f780d02b894001e004f4b4a350ec38 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Fri, 7 Apr 2017 18:59:09 +0800 Subject: [PATCH] memory: provide iommu_replay_all() This is an "global" version of existing memory_region_iommu_replay() - we announce the translations to all the registered notifiers, instead of a specific one.
