    s390/io: Add pci_iomap_wc() and pci_iomap_wc_range() · ee03c586
    Luis R. Rodriguez authored
    The following commit:
    
      1b3d4200 ("PCI: Add pci_iomap_wc() variants")
    
    Introduced pci_iomap_wc() variants but broke the s390 build,
    because s390 requires its own implementation of pcio_iomap*()
    calls.
    
    The reason for that is that:
    
      "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"
    
    so it has its own lookup/lock solution and 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.
