From 0f3b3956c4946a6a991974943e3de33ae3d2523f Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 30 Jan 2012 00:23:38 +0200 Subject: [PATCH] mips: use the the PCI controller's io_map_base commit eab90291d35438bcebf7c3dc85be66d0f24e3002 (mips: switch to GENERIC_PCI_IOMAP) 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.
