    Subject[PATCH 0/3] arch: fix ioport mapping on mips,sh
    Kevin Cernekee reported that recent cleanup
    that replaced pci_iomap with a generic function
    failed to take into account the differences
    in io port handling on mips and sh architectures.

    Rather than revert the changes reintroducing the
    code duplication, this patchset fixes this
    by adding ability for architectures to override
    ioport mapping for pci devices.

    I put this in my tree that feeds into linux-next
    and intend to ask Linus to pull this fix if this
    doesn't cause any issues and there are no objections.

    The patches were tested on x86 and compiled on mips and sh.
    Would appreciate reviews/acks/testing reports.

    Michael S. Tsirkin (3):
    lib: add NO_GENERIC_PCI_IOPORT_MAP
    mips: use the the PCI controller's io_map_base
    sh: use the the PCI channels's io_map_base
