x86/ia64: intel-iommu: move to drivers/iommu/
This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Note: to move intel-iommu.c, the declaration of pci_find_upstream_pcie_bridge() has to move from drivers/pci/pci.h to include/linux/pci.h. This is handled in this patch, too. As suggested, also drop DMAR's EXPERIMENTAL tag while we're at it. Compile-tested on x86_64. Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
