gt64xxx: fix crash in gt64120_pci_mapping() The map/unmap code was assymetric - unmap used the local MemoryRegion while map used isa_mmio_init(), which cannot handle dynamic mappings. Fix by using isa_mmio_setup() and the local MemoryRegion. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
