Arnd Bergmann c1ef322491 sparc: Use generic pci_mmap_resource_range() ... The main feature of the sparc-specific implementation of pci_mmap_resource_range() is that it allows mapping the entire PCI I/O space for a PCI host bridge using the /proc/bus/pci interface on a bridge device. The generic implementation cannot do this, but it also appears that this got broken for sparc by commit 9eff02e204 ("PCI: check mmap range of /proc/bus/pci files too"), which enforces that each address is part of a BAR for kernels after 2.6.28. Remove it all, assuming that the corresponding user space code has already been changed to access /dev/ioport instead a long time ago. Add pci_iobar_pfn() to make it possible to map I/O resources. This is adapted from the powerpc version.
