Merge branch 'core-iommu-for-linus' of git://git./linux/kernel/git/tip/linux-2.6-tip

* 'core-iommu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  iommu/core: Fix build with INTR_REMAP=y && CONFIG_DMAR=n
  iommu/amd: Don't use MSI address range for DMA addresses
  iommu/amd: Move missing parts to drivers/iommu
  iommu: Move iommu Kconfig entries to submenu
  x86/ia64: intel-iommu: move to drivers/iommu/
  x86: amd_iommu: move to drivers/iommu/
  msm: iommu: move to drivers/iommu/
  drivers: iommu: move to a dedicated folder
  x86/amd-iommu: Store device alias as dev_data pointer
  x86/amd-iommu: Search for existind dev_data before allocting a new one
  x86/amd-iommu: Allow dev_data->alias to be NULL
  x86/amd-iommu: Use only dev_data in low-level domain attach/detach functions
  x86/amd-iommu: Use only dev_data for dte and iotlb flushing routines
  x86/amd-iommu: Store ATS state in dev_data
  x86/amd-iommu: Store devid in dev_data
  x86/amd-iommu: Introduce global dev_data_list
  x86/amd-iommu: Remove redundant device_flush_dte() calls
  iommu-api: Add missing header file

Fix up trivial conflicts (independent additions close to each other) in
drivers/Makefile and include/linux/pci.h
