Subject: [PATCH 08/34] x86/amd-iommu: Remove iommu_flush_domain function
Date: Fri, 27 Nov 2009 14:55:19 +0100	[thread overview]
Message-ID: <1259330145-14865-9-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1259330145-14865-1-git-send-email-joerg.roedel@amd.com>

This iommu_flush_tlb_pde function does essentially the same.
So the iommu_flush_domain function is redundant and can be
removed.
