From: Joerg Roedel Date: Fri, 20 Nov 2009 15:08:55 +0000 (+0100) Subject: x86/amd-iommu: Remove iommu_flush_domain function X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=601367d76bd1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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.
