From 5cdede2408e80f190c5595e592c24e77c1bf44b2 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Mon, 4 Apr 2011 15:55:18 +0200 Subject: PCI: Move ATS declarations in seperate header file This patch moves the relevant declarations from the local header file in drivers/pci to a more accessible locations so that it can be used by the AMD IOMMU driver too. The file is named pci-ats.h because support for the PCI PRI capability will also be added there in a later patch-set.
