From: "Luis R. Rodriguez" <redacted> S390 requires its own implementation of pcio_iomap*() calls is because it has its "BAR spaces are not disjunctive on s390 so we need the bar parameter of pci_iomap to find the corresponding device and create the mapping cookie" -- in summary, it has its own lookup/lock solution. It does not include asm-generic/pci_iomap.h Since it currenty maps ioremap_wc() to ioremap_nocache() and that's the architecture default we can easily just map the wc calls to the default calls as well.

I fixed the changelog to explain all this. Also, is there any other architecture that got broken by: 1b3d4200c1e0 PCI: Add pci_iomap_wc() variants ? Thanks, Ingo
