Fix pci_unmap_addr() et al on i386.
commit 788d84bba47ea3eb377f7a3ae4fd1ee84b84877b upstream.
We can run a 32-bit kernel on boxes with an IOMMU, so we need
pci_unmap_addr() etc. to work -- without it, drivers will leak mappings.
To be honest, this whole thing looks like it's more pain than it's
worth; I'm half inclined to remove the no-op #else case altogether.
But this is the minimal fix, which just does the right thing if
CONFIG_DMAR is set.
