Merge branch 'pci/resource'

- Replace sparc pci_mmap_page_range() wrapper.  This still leaves a
  sparc-specific pci_mmap_resource_range(), but it's only one interface
  instead of two (Arnd Bergmann)

- Remove sparc-specific pci_mmap_resource_range() by implementing
  pci_iobar_pfn().  This removes the ability to map the entire PCI I/O
  space using /proc/bus/pci, but we believe that's already been broken
  since v2.6.28 (Arnd Bergmann)

* pci/resource:
  sparc: Use generic pci_mmap_resource_range()
  PCI: Remove pci_mmap_page_range() wrapper
