From 2842e5bf3115193f05dc9dac20f940e7abf44c1a Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Thu, 18 Sep 2008 15:23:43 +0200 Subject: x86: move GART TLB flushing options to generic code The GART currently implements the iommu=[no]fullflush command line parameters which influence its IO/TLB flushing strategy. This patch makes these parameters generic so that they can be used by the AMD IOMMU too.
