From 8301da53fbc1dff07c96f7ebf32bda331e4775e3 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Wed, 30 Jul 2014 16:04:38 +0200 Subject: [PATCH] iommu/amd: Remove change_pte mmu_notifier call-back All calls to this call-back are wrapped with mmu_notifer_invalidate_range_start()/end(), making this notifier pretty useless, so remove it.
