4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
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.
