From 601367d76bd19b7eea2286ae99e5b1cb5d74f38d Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Fri, 20 Nov 2009 16:08:55 +0100 Subject: [PATCH] x86/amd-iommu: Remove iommu_flush_domain function This iommu_flush_tlb_pde function does essentially the same. So the iommu_flush_domain function is redundant and can be removed.
