Subject: parisc: pci memory bar assignment fails with 64bit kernels on dino/cujo

From: Thomas Bogendoerfer <[email protected]>

commit 4098116039911e8870d84c975e2ec22dab65a909 upstream.

For 64bit kernels the lmmio_space_offset of the host bridge window isn't set correctly on systems with dino/cujo PCI host bridges. This leads to not assigned memory bars and failing drivers, which need to use these bars.
