Linville" , Michael Witten , linux-mips@linux-mips.org, linux-kernel@vger.kernel.org, linux-sh@vger.kernel.org, linux-arch@vger.kernel.org commit eab90291d35438bcebf7c3dc85be66d0f24e3002 failed to take into account the PCI controller's io_map_base for mapping IO BARs. This also caused a new warning on mips. Fix this, without re-introducing code duplication, by setting NO_GENERIC_PCI_IOPORT_MAP and supplying a mips-specific __pci_ioport_map.
