I don't think this is the right thing.  The probem is that
the PCI code shouldn't really be using ioremap_page_range if it is
not an ioremap area, but instead directly call into
vmap_range_noflush (or an added back vmap_range to avoid all the
duplication) similar to the vunmap case in vunmap_range.
