From e93be88d7ec9d183c1cca51eabe040c051cdb687 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Thu, 10 Jul 2008 08:27:49 +0900 Subject: [PATCH] x86: clean up iommu.h and gart.h This remove lots of duplications in iommu.h and gart.h. The end result of this patch is: - iommu.h is a header file for everyone related with IOMMUs. - gart.h is the private header file. Only pci-gart_64.c and its friends include it.
