17f5b569e0 iommu/amd: Don't use MSI address range for DMA addresses
Reserve the MSI address range in the address allocator so
that MSI addresses are not handed out as dma handles.

403f81d8ee iommu/amd: Move missing parts to drivers/iommu
A few parts of the driver were missing in drivers/iommu.
Move them there to have the complete driver in that
directory.

166e9278a3 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.

ab493a0f0f drivers: iommu: move to a dedicated folder
Create a dedicated folder for iommu drivers, and move the base
iommu implementation over there.

Grouping the various iommu drivers in a single location will help
finding similar problems shared by different platforms, so they
could be solved once, in the iommu framework, instead of solved
differently (or duplicated) in each driver.
